You would need also to import the HttpClientModule
from Angular '@angular/common/http'
into your main AppModule for making HTTP requests.
app.module.ts
import { HttpClientModule } from '@angular/common/http';
import { ServiceService } from '../../../services/service.service';
@NgModule({
imports: [
HttpClientModule
],
providers: [
ServiceService
]
})
export class AppModule {...}
If your items in the array are not primitive you can use spread operator to do that.
this.plansCopy = this.plans.map(obj => ({...obj}));

Pod is not started due to problem coming after initialization of POD.
Check and use command to get docker container of pod
docker ps -a | grep private-reg
Output will be information of docker container with id.
See docker logs:
docker logs -f <container id>
If you are using foreignkey then you have to use "on_delete=models.CASCADE" as it will eliminate the complexity developed after deleting the original element from the parent table. As simple as that.
categorie = models.ForeignKey('Categorie', on_delete=models.CASCADE)
There are few mistakes you are doing:
addRow
methodsplice
method to remove an element from an array at particular index.my-item
component, where this can be modified.You can see working code here.
addRow(){
this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
this. itemList.splice(index, 1)
}
That's because abc
is undefined at the moment of the template rendering. You can use safe navigation operator (?
) to "protect" template until HTTP call is completed:
{{abc?.xyz?.name}}
You can read more about safe navigation operator here.
Update:
Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf
directive to overcome this problem:
<div *ngIf="arr && arr.length > 0">
{{arr[0].name}}
</div>
Read more about NgIf
directive here.
You can try the require
function. like this:
<img :src="require(`@/xxx/${name}.png`)" alt class="icon" />
You need add Firebase Gradle buildscript dependency in build.gradle (project-level)
classpath 'com.google.gms:google-services:3.1.0'
and add Firebase plugin for Gradle in app/build.gradle
apply plugin: 'com.google.gms.google-services'
build.gradle will include these new dependencies:
compile 'com.google.firebase:firebase-database:11.0.4'

You could add the default rule with the alter table,
ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP DEFAULT NOW()
then immediately set to null all the current existing rows:
UPDATE mytable SET created_at = NULL
Then from this point on the DEFAULT
will take effect.
I also had this issue. Initially, a proxy was set and work fine. Then I connected to a network where it doesn't go through a proxy. After unsetting proxy pip again get works.
unset http_proxy; unset http_prox; unset HTTP_PROXY; unset HTTPS_PROXY
There is a get method in HashMap:
for (String keys : objectSet.keySet())
{
System.out.println(keys + ":"+ objectSet.get(keys));
}
If you want to be more targeted to the actual child component than you should do the follow. This way, if other child components share the same class name, they won't be affected.

The package @angular/router
has the Resolve
property for routes. So you can easily resolve data before rendering a route view.
See: https://angular.io/docs/ts/latest/api/router/index/Resolve-interface.html
Example from docs as of today, August 28, 2017:
class Backend {
fetchTeam(id: string) {
return 'someTeam';
}
}
@Injectable()
class TeamResolver implements Resolve<Team> {
constructor(private backend: Backend) {}
resolve(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<any>|Promise<any>|any {
return this.backend.fetchTeam(route.params.id);
}
}
@NgModule({
imports: [
RouterModule.forRoot([
{
path: 'team/:id',
component: TeamCmp,
resolve: {
team: TeamResolver
}
}
])
],
providers: [TeamResolver]
})
class AppModule {}
Now your route will not be activated until the data has been resolved and returned.
Accessing Resolved Data In Your Component
To access the resolved data from within your component at runtime, there are two methods. So depending on your needs, you can use either:
route.snapshot.paramMap
which returns a string, or the route.paramMap
which returns an Observable you can .subscribe()
to. Example:
// the no-observable method
this.dataYouResolved= this.route.snapshot.paramMap.get('id');
// console.debug(this.licenseNumber);
// or the observable method
this.route.paramMap
.subscribe((params: ParamMap) => {
// console.log(params);
this.dataYouResolved= params.get('id');
return params.get('dataYouResolved');
// return null
});
console.debug(this.dataYouResolved);
I hope that helps.
The short answer: seems like a totally reasonable approach to the asynchrony problem to me. With a couple caveats.
I had a very similar line of thought when working on a new project we just started at my job. I was a big fan of vanilla Redux's elegant system for updating the store and rerendering components in a way that stays out of the guts of a React component tree. It seemed weird to me to hook into that elegant dispatch
mechanism to handle asynchrony.
I ended up going with a really similar approach to what you have there in a library I factored out of our project, which we called react-redux-controller.
I ended up not going with the exact approach you have above for a couple reasons:
dispatch
itself via lexical scope. This limits the options for refactoring once that connect
statement gets out of hand -- and it's looking pretty unwieldy with just that one update
method. So you need some system for letting you compose those dispatcher functions if you break them up into separate modules.Take together, you have to rig up some system to allow dispatch
and the store to be injected into your dispatching functions, along with the parameters of the event. I know of three reasonable approaches to this dependency injection:
dispatch
middleware approaches, but I assume they're basically the same.connect
, rather than having to work directly with the raw, normalized store.this
context, through a variety of possible mechanisms.Update
It occurs to me that part of this conundrum is a limitation of react-redux. The first argument to connect
gets a state snapshot, but not dispatch. The second argument gets dispatch but not the state. Neither argument gets a thunk that closes over the current state, for being able to see updated state at the time of a continuation/callback.
Here is how to do a quick check to see if n.fn.init[0]
is caused by your DOM-elements not loading in time. Delay your selector function by wrapping it in setTimeout
function like this:
function timeout(){
...your selector function that returns n.fn.init[0] goes here...
}
setTimeout(timeout, 5000)
This will cause your selector function to execute with a 5 second delay, which should be enough for pretty much anything to load.
This is just a coarse hack to check if DOM is ready for your selector function or not. This is not a (permanent) solution.
The preferred ways to check if the DOM is loaded before executing your function are as follows:
1) Wrap your selector function in
$(document).ready(function(){ ... your selector function... };
2) If that doesn't work, use DOMContentLoaded
3) Try window.onload, which waits for all the images to load first, so its least preferred
window.onload = function () { ... your selector function... }
4) If you are waiting for a library to load that loads in several steps or has some sort of delay of its own, then you might need some complicated custom solution. This is what happened to me with "MathJax" library. This question discusses how to check when MathJax library loaded its DOM elements, if it is of any help.
5) Finally, you can stick with hard-coded setTimeout
function, making it maybe 1-3 seconds. This is actually the very least preferred method in my opinion.
This list of fixes is probably far from perfect so everyone is welcome to edit it.
I had the same problem. It worked for me when i removed the private modifier from the Autowired objects.

Your code is missing
@Component({

You can't use directives like routerLink
or router-outlet
without making them known to your component.
While directive names were changed to be case-sensitive in Angular2, elements still use -
in the name like <router-outlet>
to be compatible with the web-components spec which require a -
in the name of custom elements.
register globally
To make ROUTER_DIRECTIVES
globally available, add this provider to bootstrap(...)
:
provide(PLATFORM_DIRECTIVES, {useValue: [ROUTER_DIRECTIVES], multi: true})
then it's no longer necessary to add ROUTER_DIRECTIVES
to each component.
Adding to the accepted answer by Luke West. If you have any entitlements:
The reason must be somewhere else. Using only Spring Boot 1.2.2 out of the box with no configuration, it Just Works. Have a look at this repo - can you get it to break?
https://github.com/konrad-garus/so-yaml
Are you sure the YAML file looks exactly the way you pasted? No extra whitespace, characters, special characters, mis-indentation or something of that sort? Is it possible you have another file elsewhere in the search path that is used instead of the one you're expecting?
Migration files must match the pattern *_*.php
, or else they won't be found. Since users.php
does not match this pattern (it has no underscore), this file will not be found by the migrator.
Ideally, you should be creating your migration files using artisan:
php artisan make:migration create_users_table
This will create the file with the appropriate name, which you can then edit to flesh out your migration. The name will also include the timestamp, to help the migrator determine the order of migrations.
You can also use the --create
or --table
switches to add a little bit more boilerplate to help get you started:
php artisan make:migration create_users_table --create=users
The documentation on migrations can be found here.
Create simple ajax combo with de initial seleted value for select2 4.0.3

$option.removeData(); // remove any caching data that might be associated
input.trigger('change'); // notify JavaScript components of possible changes
});
}
}
};
and the php server side
<?php
if (isset($_GET['getQuery']) && isset($_GET['table']) && isset($_GET['fieldname'])) {
//parametros carga de petición
parse_str(file_get_contents("php://input"), $data);
$data = (object) $data;

recyclerView.removeAllViewsInLayout();
The above line would help you remove all views from the layout.
For you:
@Override
protected void onRestart() {
super.onRestart();
recyclerView.removeAllViewsInLayout(); //removes all the views
//then reload the data
PostCall doPostCall = new PostCall(); //my AsyncTask...
doPostCall.execute();
}
As none of the above options was ideal to me I ended up using map:
this.setState({items: this.state.items.map((item,idx)=> idx!==1 ?item :{...item,name:'new_name'}) })
I was trying to do the same thing in Laravel 5.8 and got an error about calling pluck statically. For my solution I used the following. The collection clearly was called todoStatuses.
<div class="row mb-2">
<label for="status" class="mr-2">Status:</label>
{{ Form::select('status',
$todoStatuses->pluck('status', 'id'),
null,
['placeholder' => 'Status']) }}
</div>
I had a similar issue with Spring Data MongoDB: I had to add the package path to @EnableMongoRepositories
Instead of using Input class you can also use old() helper to make this even shorter.
<option {{ old('name') == $key ? "selected" : "" }} value="{{ $value }}">
I consider state to be for view only information and data that should persist beyond the view state is better stored as props. URL params are useful when you want to be able to link to a page or share the URL deep in to the app but otherwise clutter the address bar.
Take a look at Redux-Persist (if you're using redux) https://github.com/rt2zz/redux-persist
I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
I had this problem today using any of concat, append or merge, and I got around it by adding a helper column sequentially numbered and then doing an outer join
helper=1
for i in df1.index:
df1.loc[i,'helper']=helper
helper=helper+1
for i in df2.index:
df2.loc[i,'helper']=helper
helper=helper+1
df1.merge(df2,on='helper',how='outer')
htmlStr
is string then You need to Date
and Time
variables to string
while (reader.Read())
{
DateTime Date = reader.GetDateTime(0);
DateTime Time = reader.GetDateTime(1);
htmlStr += "<tr><td>" + Date.ToString() + "</td><td>" +
Time.ToString() + "</td></tr>";
}
thought I would update on this.
Found out that adding to the VB Module behind the spreadsheet does not actually register as a Macro.
So here is the solution:
Code
Function LastSavedTimeStamp() As Date
LastSavedTimeStamp = ActiveWorkbook.BuiltinDocumentProperties("Last Save Time")
End Function
Code
=LastSavedTimeStamp()
This error can happen if you instantiate a class that relies on that table, for example in views.py.
If the .htaccess

You can't add reference to table that have already data inside.
Change:
user = models.OneToOneField(User)
to:
user = models.OneToOneField(User, default = "")
do:
python manage.py makemigrations

change again:
user = models.OneToOneField(User)
do migration again:
python manage.py makemigrations
python manage.py migrate
We face this issue but had different reason, here is the reason:
In our project found multiple bean entry with same bean name. 1 in applicationcontext.xml & 1 in dispatcherServlet.xml
Example:
<bean name="dataService" class="com.app.DataServiceImpl">
<bean name="dataService" class="com.app.DataServiceController">
& we are trying to autowired by dataService name.
Solution: we changed the bean name & its solved.
In my case, I was calling this.setState({})
correctly, but I my function wasn't bound to this, so it wasn't working. Adding .bind(this)
to the function call or doing this.foo = this.foo.bind(this)
in the constructor fixed it.
The following worked really well for me. I needed to redraw the datatable with a different subset of the data based on a parameter.
table.ajax.url('NewDataUrl?parameter=' + param).load();
If your data is static, then use this:
table.ajax.url('NewDataUrl').load();
Using Environment class we can get application. Properties values
@Autowired,
private Environment env;
and access using
String password =env.getProperty(your property key);
I ran into this issue when I use djangocms and added a plugin (in my case: djangocms-cascade). Of course I had to add the plugin to the INSTALLED_APPS. But the order is here important.
To place 'cmsplugin_cascade' before 'cms' solved the issue.
This provided a simple solution: Set data in Select2 after insert with AJAX
$("#select2").select2('data', {id: newID, text: newText});
You need a click listener which calls addActivityItem
if less than 2 options exist:
var activities = document.getElementById("activitySelector");
activities.addEventListener("click", function() {
var options = activities.querySelectorAll("option");
var count = options.length;
if(typeof(count) === "undefined" || count < 2)
{
addActivityItem();
}
});
activities.addEventListener("change", function() {
if(activities.value == "addNew")
{
addActivityItem();
}
});
function addActivityItem() {
// ... Code to add item here
}

You basically have 3 options to prevent the PowerShell Console window from closing, that I describe in more detail on my blog post.
PowerShell -NoExit "C:\SomeFolder\SomeScript.ps1"
Read-Host -Prompt "Press Enter to exit"
Global Fix: Change your registry key to always leave the PowerShell Console window open after the script finishes running. Here's the 2 registry keys that would need to be changed:
? Open With ? Windows PowerShell
When you right-click a .ps1 file and choose Open With
Registry Key: HKEY_CLASSES_ROOT\Applications\powershell.exe\shell\open\command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "%1"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "& \"%1\""
? Run with PowerShell
When you right-click a .ps1 file and choose Run with PowerShell (shows up depending on which Windows OS and Updates you have installed).
Registry Key: HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\0\Command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -NoExit "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & \"%1\""
You can download a .reg file from my blog to modify the registry keys for you if you don't want to do it manually.
It sounds like you likely want to use option #2. You could even wrap your whole script in a try block, and only prompt for input if an error occurred, like so:
try
{
# Do your script's stuff
}
catch
{
Write-Error $_.Exception.ToString()
Read-Host -Prompt "The above error occurred. Press Enter to exit."
}

I'm going to make a couple of assumptions in my answer. I'm assuming your data starts in A1 and there are no empty cells in the first column of each row that has data.
This code will:
This is not a fast method but will iterate through each one individually as you suggested is your intention.
Sub iterateThroughAll()
ScreenUpdating = False
Dim wks As Worksheet
Set wks = ActiveSheet
Dim rowRange As Range
Dim colRange As Range
Dim LastCol As Long
Dim LastRow As Long
LastRow = wks.Cells(wks.Rows.Count, "A").End(xlUp).Row
Set rowRange = wks.Range("A1:A" & LastRow)
'Loop through each row
For Each rrow In rowRange
'Find Last column in current row
LastCol = wks.Cells(rrow, wks.Columns.Count).End(xlToLeft).Column
Set colRange = wks.Range(wks.Cells(rrow, 1), wks.Cells(rrow, LastCol))
'Loop through all cells in row up to last col
For Each cell In colRange
'Do something to each cell
Debug.Print (cell.Value)
Next cell
Next rrow
ScreenUpdating = True
End Sub
In the accepted answer you get annoying spacing between the visible rows when the expandable row is hidden. You can get rid of that by adding this to css:
.collapse-row.collapsed + tr {
display: none;
}
'+' is adjacent sibling selector, so if you want your expandable row to be the next row, this selects the next tr following tr named collapse-row.

The res.render stuff will throw an error if you're not using a view engine.
If you just want to serve json replace the res.render('error', { error: err });
lines in your code with:
res.json({ error: err })
PS: People usually also have message in the returned object:
res.status(err.status || 500);
res.json({
message: err.message,
error: err
});

The best solution is to acknowledge the asynchronous nature of the download and design for it.
In other words, decide what your application should look like while the data is downloading. Have the page constructor set up that view, and start the download. When the download completes update the page to display the data.
I have a blog post on asynchronous constructors that you may find useful. Also, some MSDN articles; one on asynchronous data-binding (if you're using MVVM) and another on asynchronous best practices (i.e., you should avoid async void
).
Json.Net prefers to use the default (parameterless) constructor on an object if there is one. If there are multiple constructors and you want Json.Net to use a non-default one, then you can add the [JsonConstructor]
attribute to the constructor that you want Json.Net to call.
[JsonConstructor]
public Result(int? code, string format, Dictionary<string, string> details = null)
{
...
}
It is important that the constructor parameter names match the corresponding property names of the JSON object (ignoring case) for this to work correctly. You do not necessarily have to have a constructor parameter for every property of the object, however. For those JSON object properties that are not covered by the constructor parameters, Json.Net will try to use the public property accessors (or properties/fields marked with [JsonProperty]
) to populate the object after constructing it.
If you do not want to add attributes to your class or don't otherwise control the source code for the class you are trying to deserialize, then another alternative is to create a custom JsonConverter to instantiate and populate your object. For example:
class ResultConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(Result));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
// Load the JSON for the Result into a JObject
JObject jo = JObject.Load(reader);
// Read the properties which will be used as constructor parameters
int? code = (int?)jo["Code"];
string format = (string)jo["Format"];
// Construct the Result object using the non-default constructor
Result result = new Result(code, format);
// (If anything else needs to be populated on the result object, do that here)
// Return the result
return result;
}
public override bool CanWrite
{
get { return false; }
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
Then, add the converter to your serializer settings, and use the settings when you deserialize:
JsonSerializerSettings settings = new JsonSerializerSettings();
settings.Converters.Add(new ResultConverter());
Result result = JsonConvert.DeserializeObject<Result>(jsontext, settings);

// Here the client data from API only have the "name" field
// If we want to use the Client class methods on this data object we need to:
let clientWithType = Object.assign(new Client(), clientData)
clientWithType.displayName()
})
But this method will not work on nested objects, sadly.
In the case you're interested in extremely minor, almost immeasurable performance increases, add a constructor to your Line
class, giving you such:
public class Line
{
public Line(string sku, int qty)
{
this.Sku = sku;
this.Qty = qty;
}
public string Sku { get; set; }
public int Qty { get; set; }
}
Then create a specialized collection class based on List<Line>
with one new method, Add
:
public class LineList : List<Line>
{
public void Add(string sku, int qty)
{
this.Add(new Line(sku, qty));
}
}
Then the code which populates your list gets a bit less verbose by using a collection initializer:
LineList myLines = new LineList
{
{ "ABCD1", 1 },
{ "ABCD2", 1 },
{ "ABCD3", 1 }
};
And, of course, as the other answers state, it's trivial to extract the SKUs into a string array with LINQ:
string[] mySKUsArray = myLines.Select(myLine => myLine.Sku).ToArray();
You need to create a service to be able to share data between controllers.
app.factory('myService', function() {
var savedData = {}
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
});
In your controller A:
myService.set(yourSharedData);
In your controller B:
$scope.desiredLocation = myService.get();
Remember to inject myService in the controllers by passing it as a parameter.
I have an example about this.

You can start with a google sheet set up with a main page and drop down source page like shown below.
You can set up the first column drop down through the normal Data > Validations menu prompts.
Main Page
Drop Down Source Page
After that, you need to set up a script with the name onEdit
. (If you don't use that name, the getActiveRange() will do nothing but return cell A1)
And use the code provided here:
function onEdit() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.getActiveSheet();
var myRange = SpreadsheetApp.getActiveRange();
var dvSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Categories");
var option = new Array();
var startCol = 0;
if(sheet.getName() == "Front Page" && myRange.getColumn() == 1 && myRange.getRow() > 1){
if(myRange.getValue() == "Category 1"){
startCol = 1;
} else if(myRange.getValue() == "Category 2"){
startCol = 2;
} else if(myRange.getValue() == "Category 3"){
startCol = 3;
} else if(myRange.getValue() == "Category 4"){
startCol = 4;
} else {
startCol = 10
}
if(startCol > 0 && startCol < 10){
option = dvSheet.getSheetValues(3,startCol,10,1);
var dv = SpreadsheetApp.newDataValidation();
dv.setAllowInvalid(false);
//dv.setHelpText("Some help text here");
dv.requireValueInList(option, true);
sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).setDataValidation(dv.build());
}
if(startCol == 10){
sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).clearDataValidations();
}
}
}
After that, set up a trigger in the script editor screen by going to Edit > Current Project Triggers. This will bring up a window to have you select various drop downs to eventually end up at this:
You should be good to go after that!

Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js
node_modules/
app/
index.html
server.js
After printing out the __dirname
path, I realized that the __dirname
path was where my server was running (app/
).
So, the answer to your question is this:
If your server.js
file is in the same folder as the files you are trying to render, then
app.use( express.static( path.join( application_root, 'site') ) );
should actually be
app.use(express.static(application_root));
The only time you would want to use the original syntax that you had would be if you had a folder tree like so:
app/
index.html
node_modules
server.js
where index.html
is in the app/
directory, whereas server.js
is in the root directory (i.e. the same level as the app/
directory).
Side note: Intead of calling the path
utility, you can use the syntax application_root + 'site'
to join a path.
Overall, your code could look like:
// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration
//Create server
var app = express();
// Configure server
app.configure( function() {
//Don't change anything here...
//Where to serve static content
app.use( express.static( application_root ) );
//Nothing changes here either...
});
//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});
SQL Server 2005, 2008, 2012 or 2014:
SELECT * FROM information_schema.tables WHERE TABLE_TYPE='BASE TABLE' AND TABLE_SCHEMA = 'dbo'
For more details: How do I get list of all tables in a database using TSQL?
change the code to the following
<%! List eList = (ArrayList)session.getAttribute("empList");%>
....
<table>
<%
for(int i=0; i<eList.length;i++){%>
<tr>
<td><%= ((Employee)eList[i]).getEid() %></td>
<td><%= ((Employee)eList[i]).getEname() %></td>
</tr>
<%}%>
</table>
Query query = session.createQuery("from Employee");
Note: from Employee. here Employee is not your table name it's POJO name.
Easiest way
make a public static method containing viewpager.setAdapter
make adapter and viewpager static
public static void refreshFragments(){
viewPager.setAdapter(adapter);
}
call anywhere, any activity, any fragment.
MainActivity.refreshFragments();
I had to add a .toString
to the item in the values array. Without it, it would only match if the entire cell body matched the searchTerm
.
function foo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('spreadsheet-name');
var r = s.getRange('A:A');
var v = r.getValues();
var searchTerm = 'needle';
for(var i=v.length-1;i>=0;i--) {
if(v[0,i].toString().indexOf(searchTerm) > -1) {
// do something
}
}
};
Almost always use fragments. If you know that the app you are building will remain very small, the extra effort of using fragments may not be worth it, so they can be left out. For larger apps, the complexity introduced is offset by the flexibility fragments provide, making it easier to justify having them in the project. Some people are very opposed to the additional complexity involved with fragments and their lifecycles, so they never use them in their projects. An issue with this approach is that there are several APIs in Android that rely on fragments, such as ViewPager and the Jetpack Navigation library. If you need to use these options in your app, then you must use fragments to get their benefits.
Excerpt From: Kristin Marsicano. “Android Programming: The Big Nerd Ranch Guide, 4th Edition.” Apple Books.
In your configuration you have 2 PropertySourcesPlaceholderConfigurer
instances.
applicationContext.xml
<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
<property name="environment">
<bean class="org.springframework.web.context.support.StandardServletEnvironment"/>
</property>
</bean>
infraContext.xml
<context:property-placeholder location="classpath:context-core.properties"/>
By default a PlaceholderConfigurer
is going to fail-fast, so if a placeholder cannot be resolved it will throw an exception. The instance from the applicationContext.xml
file has no properties and as such will fail on all placeholders.
Solution: Remove the one from applicationContext.xml as it doesn't add anything it only breaks things.
I think this will benefit you Try this I'm using to change the language in my application
String[] districts;
Spinner sp;
......
sp = (Spinner) findViewById(R.id.sp);
districts = getResources().getStringArray(R.array.lang_array);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,districts);
sp.setAdapter(adapter);
sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long arg3) {
// TODO Auto-generated method stub
int index = arg0.getSelectedItemPosition();
Toast.makeText(getBaseContext(), "You select "+districts[index]+" id "+position, Toast.LENGTH_LONG).show();
switch(position){
case 0:
setLocal("fr");
//recreate();
break;
case 1:
setLocal("ar");
//recreate();
break;
case 2:
setLocal("en");
//recreate();
break;
default: //For all other cases, do this
setLocal("en");
//recreate();
break;
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
and this is my String Array
<string-array name="lang_array">
<item>french</item>
<item>arabic</item>
<item>english</item>
</string-array>
All solutions here doesn't really bind the model to the input because you will have to change back the dateAsString
to be saved as date
in your object (in the controller after the form will be submitted).
If you don't need the binding effect, but just to show it in the input,
a simple could be:
<input type="date" value="{{ item.date | date: 'yyyy-MM-dd' }}" id="item_date" />
Then, if you like, in the controller, you can save the edited date in this way:
$scope.item.date = new Date(document.getElementById('item_date').value).getTime();
be aware: in your controller, you have to declare your item
variable as $scope.item
in order for this to work.
This is my solution with swift 5.
To fully control the header section view, you need to use the tableView(:viewForHeaderInsection::) method in your controller, as the previous post showed. However, there is a further step: to improve performance, apple recommend not generate a new view every time but to re-use the header view, just like reuse table cell. This is by method tableView.dequeueReusableHeaderFooterView(withIdentifier: ). But the problem I had is once you start to use this re-use function, the font won't function as expected. Other things like color, alignment all fine but just font. There are some discussions but I made it work like the following.
The problem is tableView.dequeueReusableHeaderFooterView(withIdentifier:) is not like tableView.dequeneReuseCell(:) which always returns a cell. The former will return a nil if no one available. Even if it returns a reuse header view, it is not your original class type, but a UITableHeaderFooterView. So you need to do the judgement and act according in your own code. Basically, if it is nil, get a brand new header view. If not nil, force to cast so you can control.
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let reuse_header = tableView.dequeueReusableHeaderFooterView(withIdentifier: "yourHeaderID")
if (reuse_header == nil) {
let new_sec_header = YourTableHeaderViewClass(reuseIdentifier:"yourHeaderID")
new_section_header.label.text="yourHeaderString"
//do whatever to set color. alignment, etc to the label view property
//note: the label property here should be your custom label view. Not the build-in labelView. This way you have total control.
return new_section_header
}
else {
let new_section_header = reuse_section_header as! yourTableHeaderViewClass
new_sec_header.label.text="yourHeaderString"
//do whatever color, alignment, etc to the label property
return new_sec_header}
}
For run all lines of GridView don't use for
loop, use foreach
loop like:
foreach (GridViewRow row in yourGridName.Rows) //Running all lines of grid
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("chkRow") as CheckBox);
if (chkRow.Checked)
{
//if checked do something
}
}
}
I've spent a good deal of time fighting with Ionic / Angular's $state & $stateParams;
To utilize $state.go() and $stateParams you must have certain things setup and other parameters must not be present.
In my app.config() I've included $stateProvider and defined within it several states:
$stateProvider
.state('home', {
templateUrl: 'home',
controller: 'homeController'
})
.state('view', {
templateUrl: 'overview',
params: ['index', 'anotherKey'],
controller: 'overviewController'
})
The params
key is especially important. As well, notice there are NO url
keys present... utilizing stateParams and URLs do NOT mix. They are mutually exclusive to each other.
In the $state.go() call, define it as such:
$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' })
The index
and anotherKey
$stateParams variables will ONLY be populated if they are first listed in the $stateController params
defining key.
Within the controller, include $stateParams as illustrated:
app.controller('overviewController', function($scope, $stateParams) {
var index = $stateParams.index;
var anotherKey = $stateParams.anotherKey;
});
The passed variables should be available!
If you do not want to define a separate class for nested json , Defining nested json object as JsonNode should work ,for example :
{"id":2,"socket":"0c317829-69bf-43d6-b598-7c0c550635bb","type":"getDashboard","data":{"workstationUuid":"ddec1caa-a97f-4922-833f-632da07ffc11"},"reply":true}
@JsonProperty("data")
private JsonNode data;
Try this:
df.loc[len(df)]=['8/19/2014','Jun','Fly','98765']
Warning: this method works only if there are no "holes" in the index. For example, suppose you have a dataframe with three rows, with indices 0, 1, and 3 (for example, because you deleted row number 2). Then, len(df) = 3, so by the above command does not add a new row - it overrides row number 3.
As others have noted, Mongoose 4
supports this. It is very important to note that you can recurse deeper than one level too, if needed—though it is not noted in the docs:
Project.findOne({name: req.query.name})
.populate({
path: 'threads',
populate: {
path: 'messages',
model: 'Message',
populate: {
path: 'user',
model: 'User'
}
}
})
Try this
$('body').on('change', '#multiid', function() {
// your stuff
})
please check .on()
selector
I assume you want to make modal use as much screen space as possible on phones. I've made a plugin to fix this UX problem of Bootstrap modals on mobile phones, you can check it out here - https://github.com/keaukraine/bootstrap-fs-modal
All you will need to do is to apply modal-fullscreen
class and it will act similar to native screens of iOS/Android.
It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.
In Web API, it's very simple to remember how parameter binding is happening.
POST
simple types, Web API tries to bind it from the URL if you POST
complex type, Web API tries to bind it from the body of
the request (this uses a media-type
formatter).
If you want to bind a complex type from the URL, you'll use [FromUri]
in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.
public IHttpActionResult Put([FromUri] ViewModel data) { ... }
If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.
public IHttpActionResult Put([FromBody] string name) { ... }
as a side note, say you are making a PUT
request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data
parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.
var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});
and your web api action will look something like below.
public IHttpActionResult Put([FromBody] string name){ ... }
This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api
I looked into this as well, and after comparing the SqlDataAdapter.Fill method with the SqlDataReader.Load funcitons, I've found that the SqlDataAdapter.Fill method is more than twice as fast with the result sets I've been using
Used code:

string MediumTableToFill = "select top 1000 * from FooBar";
string SmallTableToFill = "select top 100 * from FooBar";
string TinyTableToFill = "select top 10 * from FooBar";
using (SqlConnection sconn = new SqlConnection("Data Source=.;initial catalog=Foo;persist security info=True; user id=bar;password=foobar;"))
{
// large data set measurements
AdapterFillLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteDataAdapterFillStep);
readerLoadLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteSqlReaderLoadStep);
// medium data set measurements

Results:
10000 rows:
Sql Data Adapter 100 times table fill speed 10000 rows: 11782 milliseconds
Sql Data Reader 100 times table load speed 10000 rows: 26047 milliseconds
1000 rows:
Sql Data Adapter 100 times table fill speed 1000 rows: 984 milliseconds
Sql Data Reader 100 times table load speed 1000 rows: 2031 milliseconds
100 rows:
Sql Data Adapter 100 times table fill speed 100 rows: 125 milliseconds
Sql Data Reader 100 times table load speed 100 rows: 235 milliseconds
10 rows:
Sql Data Adapter 100 times table fill speed 10 rows: 32 milliseconds
Sql Data Reader 100 times table load speed 10 rows: 93 milliseconds
For performance issues, using the SqlDataAdapter.Fill method is far more efficient. So unless you want to shoot yourself in the foot use that. It works faster for small and large data sets.
Very old question, but I tried everything suggested above and still could not get it resolved.
Turns out that, I had after insert/update trigger for the main table which tracked the changes by inserting the record in history table having similar structure. I increased the size in the main table column but forgot to change the size of history table column and that created the problem.
I did similar changes in the other table and error is gone.
If you're using a gridview then use the empty data template: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.emptydatatemplate.aspx

These answer are pretty outdated. Some work in certain situations, but this is in the documentation. https://select2.org/programmatic-control/add-select-clear-items#preselecting-options-in-an-remotely-sourced-ajax-select2
Basically you need create and append the selected options.
// Set up the Select2 control
$('#mySelect2').select2({
ajax: {
url: '/api/students'
}
});
// Fetch the preselected item, and add to the control
var studentSelect = $('#mySelect2');
$.ajax({
type: 'GET',
url: '/api/students/s/' + studentId
}).then(function (data) {
// create the option and append to Select2
var option = new Option(data.full_name, data.id, true, true);
studentSelect.append(option).trigger('change');
// manually trigger the `select2:select` event
studentSelect.trigger({
type: 'select2:select',
params: {
data: data
}
});
});
If you installed gradle with homebrew, then the path is:
/usr/local/Cellar/gradle/X.X/libexec
Where X.X is the version of gradle (currently 2.1)
Untested....but should work.
Dim lastrow as long
lastrow = range("D65000").end(xlup).Row
ActiveCell.FormulaR1C1 = _

Selection.AutoFill Destination:=Range("E2:E" & lastrow)
'Selection.AutoFill Destination:=Range("E2:E"& lastrow)

Only exception being are you sure your Autofill code is perfect...
Directly assign the value to model in data-ng-value
attribute.
Since Angular interpreter doesn't recognize hidden fields as part of ngModel.
<input type="hidden" name="pfuserid" data-ng-value="newPortfolio.UserId = data.Id"/>
Try this
<script type="text/javascript">
function AddItem()
{
// Create an Option object
var opt = document.createElement("option");
// Assign text and value to Option object
opt.text = "New Value";
opt.value = "New Value";
// Add an Option object to Drop Down List Box
document.getElementById('<%=DropDownList.ClientID%>').options.add(opt);
}
<script />
The Value will append to the drop down list.
You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).
This is a good understanding of data-binding. I think you've got that down.
For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.
I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.
I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.
<div rotate-on-click="45"></div>
First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.
function rotate(deg, elem) {
$(elem).css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
}
function addRotateOnClick($elems) {
$elems.each(function(i, elem) {
var deg = 0;
$(elem).click(function() {
deg+= parseInt($(this).attr('rotate-on-click'), 10);
rotate(deg, this);
});
});
}
addRotateOnClick($('[rotate-on-click]'));
app.directive('rotateOnClick', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var deg = 0;
element.bind('click', function() {
deg+= parseInt(attrs.rotateOnClick, 10);
element.css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
});
}
};
});
Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link
function (or compile
function).
Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.
This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?
The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.
Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:
Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.
Here are some things that modern frameworks are providing:
Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.
If you need to destroy a planet and you have a Death Star, use the Death star.
Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.
In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:
<clock></clock>
Done.
Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.
Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.
THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.
Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.
Ok, after the information that your Activity extends ListActivity here's a way to implement OnItemClickListener:
public class newListView extends ListView {
public newListView(Context context) {
super(context);
}
@Override
public void setOnItemClickListener(
android.widget.AdapterView.OnItemClickListener listener) {
super.setOnItemClickListener(listener);
//do something when item is clicked
}
}
By default Entity Framework uses lazy-loading for navigation properties. That's why these properties should be marked as virtual - EF creates proxy class for your entity and overrides navigation properties to allow lazy-loading. E.g. if you have this entity:
public class MemberLoan
{
public string LoandProviderCode { get; set; }
public virtual Membership Membership { get; set; }
}
Entity Framework will return proxy inherited from this entity and provide DbContext instance to this proxy in order to allow lazy loading of membership later:
public class MemberLoanProxy : MemberLoan
{
private CosisEntities db;
private int membershipId;
private Membership membership;
public override Membership Membership
{
get
{
if (membership == null)
membership = db.Memberships.Find(membershipId);
return membership;
}
set { membership = value; }
}
}
So, entity has instance of DbContext which was used for loading entity. That's your problem. You have using
block around CosisEntities usage. Which disposes context before entities are returned. When some code later tries to use lazy-loaded navigation property, it fails, because context is disposed at that moment.
To fix this behavior you can use eager loading of navigation properties which you will need later:
IQueryable<MemberLoan> query = db.MemberLoans.Include(m => m.Membership);
That will pre-load all memberships and lazy-loading will not be used. For details see Loading Related Entities article on MSDN.
One way might be;
<select name="listbox" id="listbox">
@foreach (var item in Model)
{
<option value="@item.UserRoleId">
@item.UserRole
</option>
}
</select>
public static void setListViewHeightBasedOnChildren(ListView listView) {
// ??ListView???Adapter
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()????????
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(0, 0); // ????View ???
totalHeight += listItem.getMeasuredHeight(); // ??????????
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight
+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));
// listView.getDividerHeight()?????????????
// params.height??????ListView?????????
listView.setLayoutParams(params);
}
you can use this code for listview in scrollview
In cell D2 and copied down:
=IF(COUNTIF($A$2:$A$5,C2)=0,"",VLOOKUP(C2,$A$2:$B$5,2,FALSE))
Bootstrap 3 uses the .form-control
class to style form components.
<select class="form-control">
<option value="one">One</option>
<option value="two">Two</option>
<option value="three">Three</option>
<option value="four">Four</option>
<option value="five">Five</option>
</select>
In case that the array contains objects for example if favouriteFoods
is an array of objects of the following:
{
name: 'Sushi',
type: 'Japanese'
}
you can use the following query:
PersonModel.find({"favouriteFoods.name": "Sushi"});
@Corey - It just simply strips out all invalid characters. However, your comment made me think of the answer.
The problem was that many of the fields in my database are nullable. When using SqlBulkCopy, an empty string is not inserted as a null value. So in the case of my fields that are not varchar (bit, int, decimal, datetime, etc) it was trying to insert an empty string, which obviously is not valid for that data type.
The solution was to modify my loop where I validate the values to this (repeated for each datatype that is not string)
//--- convert decimal values
foreach (DataColumn DecCol in DecimalColumns)
{
if(string.IsNullOrEmpty(dr[DecCol].ToString()))
dr[DecCol] = null; //--- this had to be set to null, not empty
else
dr[DecCol] = Helpers.CleanDecimal(dr[DecCol].ToString());
}
After making the adjustments above, everything inserts without issues.
you have to add the property Tables to the DataGridView Data Source
dataGridView1.DataSource = table.Tables[0];
This is the code what I used for the set selected value

try this on an angular framework
why dont you add a "source" column to each of the queries with a static value like
select 'source 1' as Source, column1, column2...
from table1
UNION ALL
select 'source 2' as Source, column1, column2...
from table2
The match between .val('Bruce jones')
and value="Bruce Jones"
is case-sensitive. It looks like you're capitalizing Jones in one but not the other. Either track down where the difference comes from, use id's instead of the name, or call .toLowerCase()
on both.
For me, on Android Studio 4.1, what did the trick was good ole File > Invalidate Cache & Restart
No more Fatal Signals after that. I'm sure it had something to do with the profiler, but can't be certain. I just know restarting AS stopped the crashes on my emulator.
Or you could keep it simple by doing something like this:
alert(angular.equals({}, $scope.items));
Got the same problem in 11 11 19, so sorry for possible necroposting. The only what helped was next solution:
var drop = $('#product_1'); // get our element, **must be unique**;
var settings = drop.attr('data-krajee-select2'); pick krajee attrs of our elem;
var drop_id = drop.attr('id'); // take id
settings = window[settings]; // take previous settings from window;
drop.select2(settings); // initialize select2 element with it;
$('.kv-plugin-loading').remove(); // remove loading animation;
It's, maybe, not so good, nice and precise solution, and maybe I still did not clearly understood, how it works and why, but this was the only, what keeps my select2 dropdowns, gotten by ajax, alive. Hope, this solution will be usefull or may push you in right decision in problem fixing
If I understood you right you want to have sheet1!A1 in sheet2!A1, sheet1!A2 in sheet2!A2,...right?
It might not be the best way but you may type the following
=IF(sheet1!A1<>"",sheet1!A1,"")
and drag it down to the maximum number of rows you expect.
The expression $(document).ready(function() deprecated in jQuery3.
See working fiddle with jQuery 3 here
Take into account I didn't include the showless button.
Here's the code:
JS
$(function () {
x=3;
$('#myList li').slice(0, 3).show();
$('#loadMore').on('click', function (e) {
e.preventDefault();
x = x+5;
$('#myList li').slice(0, x).slideDown();
});
});
CSS
#myList li{display:none;
}
#loadMore {
color:green;
cursor:pointer;
}
#loadMore:hover {
color:black;
}
Thanks it working
here i am done with this by qty field is zero means it shown that cells are in red color
int count = 0;
foreach (DataGridViewRow row in ItemDg.Rows)
{
int qtyEntered = Convert.ToInt16(row.Cells[1].Value);
if (qtyEntered <= 0)
{
ItemDg[0, count].Style.BackColor = Color.Red;//to color the row
ItemDg[1, count].Style.BackColor = Color.Red;
ItemDg[0, count].ReadOnly = true;//qty should not be enter for 0 inventory
}
ItemDg[0, count].Value = "0";//assign a default value to quantity enter
count++;
}
}
this also works
j=0;
for(std::vector<int>::iterator it = myvector.begin() ; it != myvector.end(); ++it){
*it = j++;
}
here's my directive:
mainApp.directive('number', function () {
return {
link: function (scope, el, attr) {
el.bind("keydown keypress", function (event) {
//ignore all characters that are not numbers, except backspace, delete, left arrow and right arrow
if ((event.keyCode < 48 || event.keyCode > 57) && event.keyCode != 8 && event.keyCode != 46 && event.keyCode != 37 && event.keyCode != 39) {
event.preventDefault();
}
});
}
};
});

Hard to copy and paste.
Not true. Enable QuickEdit
, either in the properties of the shortcut, or in the properties of the CMD window (right-click on the title bar), and you can mark text directly. Right-click copies marked text into the clipboard. When no text is marked, a right-click pastes text from the clipboard.
Hard to resize the window.
True. Console2 (see below) does not have this limitation.
Hard to open another window (no menu options do this).
Not true. Use start cmd
or define an alias if that's too much hassle:
doskey nw=start cmd /k $*
Seems to always start in C:\Windows\System32, which is super useless.
Not true. Or rather, not true if you define a start directory in the properties of the shortcut
or by modifying the AutoRun registry value. Shift-right-click on a folder allows you to launch a command prompt in that folder.
Weird scrolling. Sometimes it scrolls down really far into blank space, and you have to scroll up to where the window is actually populated
Never happened to me.
An alternative to plain CMD is Console2, which uses CMD under the hood, but provides a lot more configuration options.
You can simply use the zoom property:
#myContainer{
zoom: 0.5;
-moz-transform: scale(0.5);
}
Where myContainer contains all the elements you're editing. This is supported in all major browsers.
in my case, creating an empty column and setting its accessor worked fine. my accessor filling user's age from dob column. toArray() function worked too.
public function getAgeAttribute()
{
return Carbon::createFromFormat('Y-m-d', $this->attributes['dateofbirth'])->age;
}
$http methods return a promise, which can't be iterated, so you have to attach the results to the scope variable through the callbacks:
$scope.documents = [];
$http.get('/Documents/DocumentsList/' + caseId)
.then(function(result) {
$scope.documents = result.data;
});
Now, since this defines the documents
variable only after the results are fetched, you need to initialise the documents
variable on scope beforehand: $scope.documents = []
. Otherwise, your ng-repeat will choke.
This way, ng-repeat will first return an empty list, because documents
array is empty at first, but as soon as results are received, ng-repeat will run again because the `documents``have changed in the success callback.
Also, you might want to alter you ng-repeat expression to:
<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">
because if your DisplayDocuments()
function is making a call to the server, than this call will be executed many times over, due to the $digest cycles.
this is a simple implementation:
lv.setOnScrollListener(new OnScrollListener() {
private int mLastFirstVisibleItem;
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if(mLastFirstVisibleItem<firstVisibleItem)
{
Log.i("SCROLLING DOWN","TRUE");
}
if(mLastFirstVisibleItem>firstVisibleItem)
{
Log.i("SCROLLING UP","TRUE");
}
mLastFirstVisibleItem=firstVisibleItem;
}
});
and if you need more precision, you can use this custom ListView class:

The Observable Collection constructor will take an IList or an IEnumerable.
If you find that you are going to do this a lot you can make a simple extension method:
public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
{
return new ObservableCollection<T>(enumerable);
}
I hope this complete example will help you.
This is the TaxiInfo class which holds information about a taxi ride:
namespace Taxi.Models
{
public class TaxiInfo
{
public String Driver { get; set; }
public Double Fare { get; set; }
public Double Distance { get; set; }
public String StartLocation { get; set; }
public String EndLocation { get; set; }
}
}
We also have a convenience model which holds a List of TaxiInfo(s):
namespace Taxi.Models
{
public class TaxiInfoSet
{
public List<TaxiInfo> TaxiInfoList { get; set; }
public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
{
TaxiInfoList = new List<TaxiInfo>();
foreach(var TaxiInfo in TaxiInfos)
{
TaxiInfoList.Add(TaxiInfo);
}
}
}
}
Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:
public ActionResult Index()
{
var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };
return View(new TaxiInfoSet(taxi1,taxi2));
}
The code for the view is as follows:
@model Taxi.Models.TaxiInfoSet
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
@foreach(var TaxiInfo in Model.TaxiInfoList){
<form>
<h1>Cost: [email protected]</h1>
<h2>Distance: @(TaxiInfo.Distance) km</h2>
<p>
Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
</p>
@Html.ActionLink("Home","Booking",TaxiInfo)
</form>
}
The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:
public ActionResult Booking(TaxiInfo Taxi)
{
return View(Taxi);
}
This returns a the following view:
@model Taxi.Models.TaxiInfo
@{
ViewBag.Title = "Booking";
}
<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>
A visual tour:
A nested dict is a dictionary within a dictionary. A very simple thing.
>>> d = {}
>>> d['dict1'] = {}
>>> d['dict1']['innerkey'] = 'value'
>>> d
{'dict1': {'innerkey': 'value'}}
You can also use a defaultdict
from the collections
package to facilitate creating nested dictionaries.
>>> import collections
>>> d = collections.defaultdict(dict)
>>> d['dict1']['innerkey'] = 'value'
>>> d # currently a defaultdict type
defaultdict(<type 'dict'>, {'dict1': {'innerkey': 'value'}})
>>> dict(d) # but is exactly like a normal dictionary.
{'dict1': {'innerkey': 'value'}}
You can populate that however you want.
I would recommend in your code something like the following:
d = {} # can use defaultdict(dict) instead
for row in file_map:
# derive row key from something
# when using defaultdict, we can skip the next step creating a dictionary on row_key
d[row_key] = {}
for idx, col in enumerate(row):
d[row_key][idx] = col
According to your comment:
may be above code is confusing the question. My problem in nutshell: I have 2 files a.csv b.csv, a.csv has 4 columns i j k l, b.csv also has these columns. i is kind of key columns for these csvs'. j k l column is empty in a.csv but populated in b.csv. I want to map values of j k l columns using 'i` as key column from b.csv to a.csv file
My suggestion would be something like this (without using defaultdict):
a_file = "path/to/a.csv"
b_file = "path/to/b.csv"
# read from file a.csv
with open(a_file) as f:
# skip headers
f.next()
# get first colum as keys
keys = (line.split(',')[0] for line in f)
# create empty dictionary:
d = {}
# read from file b.csv
with open(b_file) as f:
# gather headers except first key header
headers = f.next().split(',')[1:]
# iterate lines
for line in f:
# gather the colums
cols = line.strip().split(',')
# check to make sure this key should be mapped.
if cols[0] not in keys:
continue
# add key to dict
d[cols[0]] = dict(
# inner keys are the header names, values are columns
(headers[idx], v) for idx, v in enumerate(cols[1:]))
Please note though, that for parsing csv files there is a csv module.
You can use the EXACT
Function for exact string comparisons.
=IF(EXACT(A1, "ENG"), 1, 0)
This beautiful code here creates a table with each td having array values. Not my code, but it helped me!
var rows = 6, cols = 7;
for(var i = 0; i < rows; i++) {
$('table').append('<tr></tr>');
for(var j = 0; j < cols; j++) {
$('table').find('tr').eq(i).append('<td></td>');
$('table').find('tr').eq(i).find('td').eq(j).attr('data-row', i).attr('data-col', j);
}
}
Moment is great time manipulation library but it's considered as a legacy project, and the team is recommending to use other libraries.
date-fns is one of the best lightweight libraries, it's modular, so you can pick the functions you need and reduce bundle size (issue & statement).
Another common argument against using Moment in modern applications is its size. Moment doesn't work well with modern "tree shaking" algorithms, so it tends to increase the size of web application bundles.
import { format } from 'date-fns' // 21K (gzipped: 5.8K)
import moment from 'moment' // 292.3K (gzipped: 71.6K)
Format date with date-fns
:
// moment.js
moment().format('MM/DD/YYYY');
// => "12/18/2020"
// date-fns
import { format } from 'date-fns'
format(new Date(), 'MM/dd/yyyy');
// => "12/18/2020"

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute
<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>
Inside the controller:
vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
vm.zoneDropdown = $customService.getZone();
}
And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):
<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
<li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
<a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
</li>
</ul>
In HTML, the selected option is represented by the presence of the selected
attribute on the <option>
element like so:
<option ... selected>...</option>
Or if you're HTML/XHTML strict:
<option ... selected="selected">...</option>
Thus, you just have to let JSP/EL print it conditionally. Provided that you've prepared the selected department as follows:
request.setAttribute("selectedDept", selectedDept);
then this should do:
<select name="department">
<c:forEach var="item" items="${dept}">
<option value="${item.key}" ${item.key == selectedDept ? 'selected="selected"' : ''}>${item.value}</option>
</c:forEach>
</select>
Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)
sub myhandler(eventsource)
process(eventsource.value)
end sub
for each cell
cell.setEventHandler(myHandler)
But i dont know the syntax for achieving this in VB/VBA, or if is even possible.
Before every insert action I added below line and solved my issue,
SET SQL_MODE = '';
I'm not sure if this is the best solution,
SET SQL_MODE = ''; INSERT INTO `mytable` ( `field1` , `field2`) VALUES ('value1', 'value2');
If VBA meets the rules for VB Script then it can be called from command line by simply placing it into a text file - in this case there's no need to specifically open Outlook.
I had a need to send automated text messages to myself from the command line, so I used the code below, which is just a compressed version of @Geoff's answer above.
Most mobile phone carriers worldwide provide an email address "version" of your mobile phone number. For example in Canada with Rogers or Chatr Wireless, an email sent to <YourPhoneNumber>
@pcs.rogers.com
will be immediately delivered to your Rogers/Chatr phone as a text message.
* You may need to "authorize" the first message on your phone, and some carriers may charge an additional fee for theses message although as far as I know, all Canadian carriers provide this little-known service for free. Check your carrier's website for details.
There are further instructions and various compiled lists of worldwide carrier's Email-to-Text addresses available online such as this and this and this.
.VBS
extension, such as TextMyself.vbs
. That's all!
Just double-click the file to send a test message, or else run it from a batch file using START
.
Sub SendMessage()
Const EmailToSMSAddy = "[email protected]"
Dim objOutlookRecip
With CreateObject("Outlook.Application").CreateItem(0)
Set objOutlookRecip = .Recipients.Add(EmailToSMSAddy)
objOutlookRecip.Type = 1
.Subject = "The computer needs your attention!"
.Body = "Go see why Windows Command Line is texting you!"
.Save
.Send
End With
End Sub
START x:\mypath\TextMyself.vbs
Of course there are endless possible ways this could be adapted and customized to suit various practical or creative needs.
I have the same problem, and i realize that. When we create adapter and set it to listview, listview will point to object somewhere in memory which adapter hold, data in this object will show in listview.
adapter = new CustomAdapter(data);
listview.setadapter(adapter);
if we create an object for adapter with another data again and notifydatasetchanged():
adapter = new CustomAdapter(anotherdata);
adapter.notifyDataSetChanged();
this will do not affect to data in listview because the list is pointing to different object, this object does not know anything about new object in adapter, and notifyDataSetChanged() affect nothing. So we should change data in object and avoid to create a new object again for adapter
This is probably how you should do it:
void push(std::string&& filename)
{
{
std::lock_guard<std::mutex> lock(qMutex);
q.push(std::move(filename));
}
populatedNotifier.notify_one();
}
bool try_pop(std::string& filename, std::chrono::milliseconds timeout)
{
std::unique_lock<std::mutex> lock(qMutex);
if(!populatedNotifier.wait_for(lock, timeout, [this] { return !q.empty(); }))
return false;
filename = std::move(q.front());
q.pop();
return true;
}
I hope this would provide you with the right solution:
Syntax:
CASE
WHEN search_condition THEN statement_list
[WHEN search_condition THEN statement_list]....
[ELSE statement_list]
END CASE
Implementation:
select id, action_heading,
case when
action_type="Expense" then action_amount
else NULL
end as Expense_amt,
case when
action_type ="Income" then action_amount
else NULL
end as Income_amt
from tbl_transaction;
Here I am using CASE
statement as it is more flexible than if-then-else
. It allows more than one branch. And CASE
statement is standard SQL and works in most databases.
I believe the answer above is incorrect, the proper way to initialize with multiple values would be this...
int[] otherList ={1,2,3,4,5};
so the full answer with the proper initialization would look like this
int[] otherList ={1,2,3,4,5};
arList.addAll(Arrays.asList(otherList));
i found that i had a timer running in the background. when the activity is killed, yet the timer still running. in the timer finish callback i access fragment object to do some work, and here is the bug!!!! the fragment exists but the activity isn't.
if you have service of timer or any background threads, make sure to not access fragments objects.
It is possible to construct a struct inside the function arguments:
function({ .variable = PUT_DATA_HERE });
df[['fips', 'row']] = df['row'].str.split(' ', n=1, expand=True)
There isn't a field initialization syntax like that for objects in JavaScript or TypeScript.
Option 1:
class bar {
// Makes a public field called 'length'
constructor(public length: number) { }
}
bars = [ new bar(1) ];
Option 2:
interface bar {
length: number;
}
bars = [ {length: 1} ];
The java.util.logging
package is standard in Java SE. Its Logger
includes an overloaded log method that accepts Throwable
objects.
It will log stacktraces of exceptions and their cause for you.
For example:
import java.util.logging.Level;
import java.util.logging.Logger;
[...]
Logger logger = Logger.getAnonymousLogger();
Exception e1 = new Exception();
Exception e2 = new Exception(e1);
logger.log(Level.SEVERE, "an exception was thrown", e2);
Will log:
SEVERE: an exception was thrown
java.lang.Exception: java.lang.Exception
at LogStacktrace.main(LogStacktrace.java:21)
Caused by: java.lang.Exception
at LogStacktrace.main(LogStacktrace.java:20)
Internally, this does exactly what @philipp-wendler suggests, by the way.
See the source code for SimpleFormatter.java
. This is just a higher level interface.
Something that sometimes crops up you may/maynot be aware of
Won't always be picked up by by $_POST['delete'] when using IE. Firefox and chrome should work fine though. I use a seperate isntead which solves the problem for IE
As for your not deleting in your code above you appear to be echoing out 2x sets of check boxes both pulling the same data? Is this just a copy + paste mistake or is this actually how your code is?
If its how your code is that'll be the problem as the user could be ticking one checkbox array item but the other one will be unchecked so the php code for delete is getting confused. Either rename the 2nd check box or delete that block of html surely you don't need to display the same list twice ?
re: indexOutOfBoundsException
, your sublist args are the problem; you need to end the sublist at size-1. Being zero-based, the last element of a list is always size-1, there is no element in the size position, hence the error.
If the cart has to be stored as an object and not array (Although I would recommend storing as an []) you can always change the structure to use the ID as the key:
var element = { quantity: quantity };
cart[id] = element;
This allows you to add multiple items to the cart like so:
cart["1"] = { quantity: 5};
cart["2"] = { quantity: 10};
// Cart is now:
// { "1": { quantity: 5 }, "2": { quantity: 10 } }

Check out the library angular-cache if you like $http's built-in caching but want more control. You can use it to seamlessly augment $http cache with time-to-live, periodic purges, and the option of persisting the cache to localStorage so that it's available across sessions.
FWIW, it also provides tools and patterns for making your cache into a more dynamic sort of data-store that you can interact with as POJO's, rather than just the default JSON strings. Can't comment on the utility of that option as yet.
(Then, on top of that, related library angular-data is sort of a replacement for $resource and/or Restangular, and is dependent upon angular-cache.)
Refering to Oliver Gierke's hint:
When the manipulation of the persistance.xml does the trick, then you created a normal java-class instead of a entity-class.
When creating a new entity-class then the entry in the persistance.xml should be set by Netbeans (in my case).
But as mentioned by Oliver Gierke you can add the entry later to the persistance.xml (if you created a normal java-class).
You need to create new Book
objects then put those in a new List
:
List<Book> books_2 = books_1.Select(book => new Book(book.title)).ToList();
Update: Slightly simpler... List<T>
has a method called ConvertAll
that returns a new list:
List<Book> books_2 = books_1.ConvertAll(book => new Book(book.title));
simple query would be, just set a variable to some number you want. then update the column you need by incrementing 1 from that number. for all the rows it'll update each row id by incrementing 1
SET @a = 50000835 ;
UPDATE `civicrm_contact` SET external_identifier = @a:=@a+1
WHERE external_identifier IS NULL;
As an alternative, there's a nice 3rd party library designed just for this use case. Whereby you need to generate headers based on the data being stored in the adapter. They are called Rolodex adapters and are used with ExpandableListViews
. They can easily be customized to behave like a normal list with headers.
Using the OP's Event
objects and knowing the headers are based on the Date
associated with it...the code would look something like this:
The Activity
//There's no need to pre-compute what the headers are. Just pass in your List of objects.
EventDateAdapter adapter = new EventDateAdapter(this, mEvents);
mExpandableListView.setAdapter(adapter);
The Adapter
private class EventDateAdapter extends NFRolodexArrayAdapter<Date, Event> {
public EventDateAdapter(Context activity, Collection<Event> items) {
super(activity, items);
}
@Override
public Date createGroupFor(Event childItem) {
//This is how the adapter determines what the headers are and what child items belong to it
return (Date) childItem.getDate().clone();
}
@Override
public View getChildView(LayoutInflater inflater, int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
//Inflate your view
//Gets the Event data for this view
Event event = getChild(groupPosition, childPosition);
//Fill view with event data
}
@Override
public View getGroupView(LayoutInflater inflater, int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
//Inflate your header view
//Gets the Date for this view
Date date = getGroup(groupPosition);
//Fill view with date data
}
@Override
public boolean hasAutoExpandingGroups() {
//This forces our group views (headers) to always render expanded.
//Even attempting to programmatically collapse a group will not work.
return true;
}
@Override
public boolean isGroupSelectable(int groupPosition) {
//This prevents a user from seeing any touch feedback when a group (header) is clicked.
return false;
}
}
Refer below Code Snip
In HTML Page
<input id="test" type="number" value="0"/>
In Java Script
document.getElementById("test").value=request.responseText;// in case of String
document.getElementById("test").value=new Number(responseText);// in case of Number
Maybe a bit simpler approach with ngInit
and Lodash's debounce
method without the need of custom directive:
Controller:
$scope.items = [1, 2, 3, 4];
$scope.refresh = _.debounce(function() {
// Debounce has timeout and prevents multiple calls, so this will be called
// once the iteration finishes
console.log('we are done');
}, 0);
Template:
<ul>
<li ng-repeat="item in items" ng-init="refresh()">{{item}}</li>
</ul>
There is even simpler pure AngularJS solution using ternary operator:
Template:
<ul>
<li ng-repeat="item in items" ng-init="$last ? doSomething() : null">{{item}}</li>
</ul>
Be aware that ngInit uses pre-link compilation phase - i.e. the expression is invoked before child directives are processed. This means that still an asynchronous processing might be required.
this works too.
df = NULL
for (k in 1:10)
{
x = 1
y = 2
z = 3
df = rbind(df, data.frame(x,y,z))
}
output will look like this
df #enter
x y z #col names
1 2 3
Use the SqlDataAdapter, this would simplify everything.
//Your code to this point
DataTable dt = new DataTable();
using(var cmd = new SqlCommand("usp_GetABCD", sqlcon))
{
using(var da = new SqlDataAdapter(cmd))
{
da.Fill(dt):
}
}
and your DataTable will have the information you are looking for, so long as your stored proceedure returns a data set (cursor).
I'm successfully using the following to update options dynamically:
$control.select2('destroy').empty().select2({data: [{id: 1, text: 'new text'}]});
JQuery:
$(function () {

var email = '[email protected]';
var subject = 'Test';
var emailBody = 'Hi Sample,';
var attach = 'path';
document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody+
"?attach="+attach;
});
});
HTML:
<button class="SendEmail">Send Email</button>
I note you suggested this formula
=IF(ISNUMBER(FIND("RuhrP";F9));LOOKUP(A9;Ruhrpumpen!A$5:A$100;Ruhrpumpen!I$5:I$100);"")
.....but LOOKUP
isn't appropriate here because I assume you want an exact match (LOOKUP won't guarantee that and also data in lookup range has to be sorted), so VLOOKUP
or INDEX/MATCH
would be better....and you can also use IFERROR to avoid the IF function, i.e
=IFERROR(VLOOKUP(A9;Ruhrpumpen!A$5:Z$100;9;0);"")
Note: VLOOKUP always looks up the lookup value (A9) in the first column of the "table array" and returns a value from the nth column of the "table array" where n is defined by col_index_num, in this case 9
INDEX/MATCH is sometimes more flexible because you can explicitly define the lookup column and the return column (and return column can be to the left of the lookup column which can't be the case in VLOOKUP), so that would look like this:
=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH(A9;Ruhrpumpen!A$5:A$100;0));"")
INDEX/MATCH also allows you to more easily return multiple values from different columns, e.g. by using $ signs in front of A9 and the lookup range Ruhrpumpen!A$5:A$100, i.e.
=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH($A9;Ruhrpumpen!$A$5:$A$100;0));"")
this version can be dragged across to get successive values from column I, column J, column K etc.....
This isn't exactly intuitive, but you cannot Redim(VB6 Ref) an array if you dimmed it with dimensions. Exact quote from linked page is:
The ReDim statement is used to size or resize a dynamic array that has already been formally declared using a Private, Public, or Dim statement with empty parentheses (without dimension subscripts).
In other words, instead of dim invoices(10,0)
You should use
Dim invoices()
Redim invoices(10,0)
Then when you ReDim, you'll need to use Redim Preserve (10,row)
Warning: When Redimensioning multi-dimensional arrays, if you want to preserve your values, you can only increase the last dimension. I.E. Redim Preserve (11,row)
or even (11,0)
would fail.
Firstly, null the data source:
this.dataGridView.DataSource = null;
Then clear the rows:
this.dataGridView.Rows.Clear();
Then set the data source to the new list:
this.dataGridView.DataSource = this.GetNewValues();
If you include the library System.Data.Entity
you can use an overload of the Include()
method which takes a lambda expression instead of a string. You can then Select()
over children with Linq expressions rather than string
paths.
return DatabaseContext.Applications
.Include(a => a.Children.Select(c => c.ChildRelationshipType));
This might have changed since the original answer was written, but it looks like you can now use the Models populate function to do this without having to execute an extra findOne. See: http://mongoosejs.com/docs/api.html#model_Model.populate. You'd want to use this inside the save handler just like the findOne is.
List constructor accepts any data structure that implements Collection interface to be used to build a list.
To get all the keys from a hash map to a list:
Map<String, Integer> map = new HashMap<String, Integer>();
List<String> keys = new ArrayList<>(map.keySet());
To get all the values from a hash map to a list:
Map<String, Integer> map = new HashMap<String, Integer>();
List<Integer> values = new ArrayList<>(map.values());
Here is a very good explanation of why using Laravel's Database Seeder is preferable to using Migrations: https://web.archive.org/web/20171018135835/http://laravelbook.com/laravel-database-seeding/
Although, following the instructions on the official documentation is a much better idea because the implementation described at the above link doesn't seem to work and is incomplete. http://laravel.com/docs/migrations#database-seeding
Instead of defining: COLUMN_HEADINGS("columnHeadings")
Try defining it as: COLUMNHEADINGS("columnHeadings")
Then when you call getByName(String name) method
, call it with the upper-cased String like this: getByName(myStringVariable.toUpperCase())
I had the same problem as you, and this worked for me.
You can use something like this scopeValue[field]
, but if your field is in another object you will need another solution.
To solve all kind of situations, you can use this directive:
this.app.directive('dynamicModel', ['$compile', '$parse', function ($compile, $parse) {
return {
restrict: 'A',
terminal: true,
priority: 100000,
link: function (scope, elem) {
var name = $parse(elem.attr('dynamic-model'))(scope);
elem.removeAttr('dynamic-model');
elem.attr('ng-model', name);
$compile(elem)(scope);
}
};
}]);
Html example:
<input dynamic-model="'scopeValue.' + field" type="text">
This is based on Jim's answer,
SELECT
@field_text + SPACE(@pad_length - LEN(@field_text)) AS RightPad
,SPACE(@pad_length - LEN(@field_text)) + @field_text AS LeftPad
Advantages
Disadvantages
If you have two or more selects and use Steve McLenithan's answer, try to replace the first line with:
$('#CHOSENINPUTFIELDID_chosen > div > div input').autocomplete({
not remove suffix: _chosen
public int[] data={31, 29, 47, 48, 23, 30, 21
, 40, 23, 39, 47, 47, 42, 44, 23, 26, 44, 32, 20, 40};
public double median()
{
Arrays.sort(this.data);
double result=0;
int size=this.data.length;
if(size%2==1)
{
result=data[((size-1)/2)+1];
System.out.println(" uneven size : "+result);
}
else
{
int middle_pair_first_index =(size-1)/2;
result=(data[middle_pair_first_index+1]+data[middle_pair_first_index])/2;
System.out.println(" Even size : "+result);
}
return result;
}
At first glance your original attempt seems pretty close. I'm assuming that clockDate is a DateTime fields so try this:
IF (NOT EXISTS(SELECT * FROM Clock WHERE cast(clockDate as date) = '08/10/2012')
AND userName = 'test')
BEGIN
INSERT INTO Clock(clockDate, userName, breakOut)
VALUES(GetDate(), 'test', GetDate())
END
ELSE
BEGIN
UPDATE Clock
SET breakOut = GetDate()
WHERE Cast(clockDate AS Date) = '08/10/2012' AND userName = 'test'
END
Note that getdate gives you the current date. If you are trying to compare to a date (without the time) you need to cast or the time element will cause the compare to fail.
If clockDate is NOT datetime field (just date), then the SQL engine will do it for you - no need to cast on a set/insert statement.
IF (NOT EXISTS(SELECT * FROM Clock WHERE clockDate = '08/10/2012')
AND userName = 'test')
BEGIN
INSERT INTO Clock(clockDate, userName, breakOut)
VALUES(GetDate(), 'test', GetDate())
END
ELSE
BEGIN
UPDATE Clock
SET breakOut = GetDate()
WHERE clockDate = '08/10/2012' AND userName = 'test'
END
As others have pointed out, the merge statement is another way to tackle this same logic. However, in some cases, especially with large data sets, the merge statement can be prohibitively slow, causing a lot of tran log activity. So knowing how to logic it out as shown above is still a valid technique.
This answer will be used as a placeholder for the not fully supported position: sticky
and will be updated over time. It is currently advised to not use the native implementation of this in a production environment.
See this for the current support: https://caniuse.com/#feat=css-sticky
position: sticky
An alternative answer would be using position: sticky
. As described by W3C:
A stickily positioned box is positioned similarly to a relatively positioned box, but the offset is computed with reference to the nearest ancestor with a scrolling box, or the viewport if no ancestor has a scrolling box.
This described exactly the behavior of a relative static header. It would be easy to assign this to the <thead>
or the first <tr>
HTML-tag, as this should be supported according to W3C. However, both Chrome, IE and Edge have problems assigning a sticky position property to these tags. There also seems to be no priority in solving this at the moment.
What does seem to work for a table element is assigning the sticky property to a table-cell. In this case the <th>
cells.
Because a table is not a block-element that respects the static size you assign to it, it is best to use a wrapper element to define the scroll-overflow.

In this example I use a simple <div>
wrapper to define the scroll-overflow done with a static height of 150px
. This can of course be any size. Now that the scrolling box has been defined, the sticky <th>
elements will corespondent "to the nearest ancestor with a scrolling box", which is the div-wrapper.
position: sticky
polyfillNon-supported devices can make use of a polyfill, which implements the behavior through code. An example is stickybits, which resembles the same behavior as the browser's implemented position: sticky
.

Best:
std::string subCondition;
This creates an empty string.
This:
std::string myStr = "";
does a copy initialization - creates a temporary string from ""
, and then uses the copy constructor to create myStr
.
Bonus:
std::string myStr("");
does a direct initialization and uses the string(const char*)
constructor.
To check if a string is empty, just use empty()
.
This very helpful feature is now available starting at version 1.1.2 of AngularJS. It's considered unstable but I have used it (1.1.3) and it works fine.
Basically you can use a function to generate a templateUrl string. The function is passed the route parameters that you can use to build and return the templateUrl string.
var app = angular.module('app',[]);
app.config(
function($routeProvider) {
$routeProvider.
when('/', {templateUrl:'/home'}).
when('/users/:user_id',
{
controller:UserView,
templateUrl: function(params){ return '/users/view/' + params.user_id; }
}
).
otherwise({redirectTo:'/'});
}
);
Many thanks to https://github.com/lrlopez for the pull request.
It will give consistent behavior for add/remove operations. But while iterating you have to explicitly synchronized. Refer this link
Kind of, use the XmlAttribute
instead of XmlElement
, but it won't look like what you want. It will look like the following:
<SomeModel SomeStringElementName="testData">
</SomeModel>
The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.
// TODO: make the class generic so that an int or string can be used.
[Serializable]
public class SerializationClass
{
public SerializationClass(string value)
{
this.Value = value;
}
[XmlAttribute("value")]
public string Value { get; }
}
[Serializable]
public class SomeModel
{
[XmlIgnore]
public string SomeString { get; set; }
[XmlIgnore]
public int SomeInfo { get; set; }
[XmlElement]
public SerializationClass SomeStringElementName
{
get { return new SerializationClass(this.SomeString); }
}
}
If you already have the data "for (Parcelable currentHeadline : allHeadlines)," then why are you doing that in a separate thread?
You should poll the data in a separate thread, and when it's finished gathering it, then call your populateTables method on the UI thread:
private void populateTable() {
runOnUiThread(new Runnable(){
public void run() {
//If there are stories, add them to the table
for (Parcelable currentHeadline : allHeadlines) {
addHeadlineToTable(currentHeadline);
}
try {
dialog.dismiss();
} catch (final Exception ex) {
Log.i("---","Exception in thread");
}
}
});
}
I saw this question a lot when I worked for an address verification company. I'm posting the answer here to make it more accessible to programmers searching around with the same question. The company I was at processed billions of addresses, and we learned a lot in the process.
First, we need to understand a few things about addresses.
This means that regular expressions are out. I've seen it all, from simple regular expressions that match addresses in a very specific format, to this:
/\s+(\d{2,5}\s+)(?![a|p]m\b)(([a-zA-Z|\s+]{1,5}){1,2})?([\s|,|.]+)?(([a-zA-Z|\s+]{1,30}){1,4})(court|ct|street|st|drive|dr|lane|ln|road|rd|blvd)([\s|,|.|;]+)?(([a-zA-Z|\s+]{1,30}){1,2})([\s|,|.]+)?\b(AK|AL|AR|AZ|CA|CO|CT|DC|DE|FL|GA|GU|HI|IA|ID|IL|IN|KS|KY|LA|MA|MD|ME|MI|MN|MO|MS|MT|NC|ND|NE|NH|NJ|NM|NV|NY|OH|OK|OR|PA|RI|SC|SD|TN|TX|UT|VA|VI|VT|WA|WI|WV|WY)([\s|,|.]+)?(\s+\d{5})?([\s|,|.]+)/i
... to this where a 900+ line-class file generates a supermassive regular expression on the fly to match even more. I don't recommend these (for example, here's a fiddle of the above regex, that makes plenty of mistakes). There isn't an easy magic formula to get this to work. In theory and by theory, it's impossible to match addresses with a regular expression.
USPS Publication 28 documents the many formats of addresses that are possible, with all their keywords and variations. Worst of all, addresses are often ambiguous. Words can mean more than one thing ("St" can be "Saint" or "Street"), and there are words that I'm pretty sure they invented. (Who knew that "Stravenue" was a street suffix?)
You'd need some code that really understands addresses, and if that code does exist, it's a trade secret. But you could probably roll your own if you're really into that.
Here are some contrived (but complete) addresses:
1) 102 main street
Anytown, state
2) 400n 600e #2, 52173
3) p.o. #104 60203
Even these are possibly valid:
4) 829 LKSDFJlkjsdflkjsdljf Bkpw 12345
5) 205 1105 14 90210
Obviously, these are not standardized. Punctuation and line break are not guaranteed. Here's what's going on:
Number 1 is complete because it contains a street address and a city and state. With that information, there's enough to identify the address, and it can be considered "deliverable" (with some standardization).
Number 2 is complete because it contains a street address (with secondary/unit number) and a 5-digit ZIP code, which is enough to identify an address.
Number 3 is a complete post office box format, as it contains a ZIP code.
Number 4 is also complete because the ZIP code is unique, meaning that a private entity or corporation has purchased that address space. A unique ZIP code is for high-volume or concentrated delivery spaces. Anything addressed to ZIP code 12345 goes to General Electric in Schenectady, NY. This example won't reach anyone in particular, but the USPS would still deliver it.
Number 5 is also complete, believe it or not. With just those numbers, the full address can be discovered when parsed against a database of all possible addresses. Filling in the missing directionals, secondary designator, and ZIP+4 code is trivial when you see each number as a component. Here's what it looks like, fully expanded and standardized:
205 N 1105 W Apt 14
Beverly Hills CA 90210-5221
In most countries that provide official address data to licensed vendors, the address data itself belongs to the governing agency. In the US, the USPS owns the addresses. The same is true for Canada Post, Royal Mail, and others, though each country enforces or defines ownership a little differently. Knowing this is important since it usually forbids reverse-engineering the address database. You have to be careful how to acquire, store, and use the data.
Google Maps is a common go-to for quick address fixes, but the TOS is rather prohibitive; for example, you can't use their data or APIs without showing a Google Map, and for non-commercial purposes only (unless you pay), and you can't store the data (except for temporary caching). Makes sense. Google's data is some of the best in the world. However, Google Maps does not verify the address. If an address does not exist, it will still show you where the address would be if it did exist (try it on your own street; use a house number that you know doesn't exist). This is useful sometimes, but be aware of that.
Nominatim's usage policy is similarly limiting, especially for high volume and commercial use, and the data is mostly drawn from free sources, so it isn't as well maintained (such as the nature of open projects). However, this may still suit your needs. A great community supports it.
The USPS itself has an API, but it goes down a lot and comes with no guarantees nor support. It might also be hard to use. Some people use it sparingly with no problems. But it's easy to miss that the USPS requires that you use their API only for confirming addresses to ship through them.
Unfortunately, we've conditioned our society to expect addresses to be complicated. There are dozens of good UX articles all over the Internet about this. Still, the fact is, if you have an address form with individual fields, that's what users expect, even though it makes it harder for edge-case addresses that don't fit the format the form is expecting, or maybe the form requires a field it shouldn't. Or users don't know where to put a certain part of their address.
I could go on and on about the bad UX of checkout forms these days, but instead, I'll say that combining the addresses into a single field will be a welcome change -- people will be able to type their address how they see fit, rather than trying to figure out your lengthy form. However, this change will be unexpected and users may find it a little jarring at first. Just be aware of that.
Part of this pain can be alleviated by putting the country field out front, before the address. When they fill out the country field first, you know how to make your form appear. Maybe you have a good way to deal with single-field US addresses, so if they select the United States, you can reduce your form to a single field, otherwise show the component fields. Just things to think about!
The USPS licenses vendors through a process called CASS™ Certification to provide verified addresses to customers. These vendors have access to the USPS database, updated monthly. Their software must conform to rigorous standards to be certified, and they don't often require agreement to such limiting terms as discussed above.
Many CASS-Certified companies can process lists or have APIs: Melissa Data, Experian QAS, and SmartyStreets, to name a few.
(Due to getting flak for "advertising," I've truncated my answer at this point. It's up to you to find a solution that works for you.)
The Truth: Really, folks, I don't work at any of these companies. It's not an advertisement.
You might need to change the line
@RequestMapping(value = "/add", method = RequestMethod.GET)
to
@RequestMapping(value = "/add", method = {RequestMethod.GET,RequestMethod.POST})
The way to do this without use of plugins is to make a subclass of google's OverlayView() method.
https://developers.google.com/maps/documentation/javascript/reference?hl=en#OverlayView
You make a custom function and apply it to the map.
function Label() {
this.setMap(g.map);
};
Now you prototype your subclass and add HTML nodes:
Label.prototype = new google.maps.OverlayView; //subclassing google's overlayView
Label.prototype.onAdd = function() {
this.MySpecialDiv = document.createElement('div');
this.MySpecialDiv.className = 'MyLabel';
this.getPanes().overlayImage.appendChild(this.MySpecialDiv); //attach it to overlay panes so it behaves like markers
}
you also have to implement remove and draw functions as stated in the API docs, or this won't work.
Label.prototype.onRemove = function() {
... // remove your stuff and its events if any
}
Label.prototype.draw = function() {
var position = this.getProjection().fromLatLngToDivPixel(this.get('position')); // translate map latLng coords into DOM px coords for css positioning
var pos = this.get('position');
$('.myLabel')
.css({
'top' : position.y + 'px',
'left' : position.x + 'px'
})
;
}
That's the gist of it, you'll have to do some more work in your specific implementation.
This is stated in comments elsewhere on this page but thought it useful to pull it out into an answer:
When using an adapter, I've found that the spinnerObject.setSelection(INDEX_OF_CATEGORY2)
needs to occur after the setAdapter
call; otherwise, the first item is always the initial selection.
// spinner setup...
spinnerObject.setAdapter(myAdapter);
spinnerObject.setSelection(INDEX_OF_CATEGORY2);
This is confirmed by reviewing the AbsSpinner code for setAdapter
.
One correct way to get selected value would be
var selected_value = $('#fruit_name').val()
And then you should do
if(selected_value) { ... }
A bit late to the party... but this is easily done with some jQuery:
$(window).on('load', function() {
$('input:-webkit-autofill').each(function() {
$(this).after($(this).clone(true).val('')).remove();
});
});
If I understand you correctly you are asking about including nested properties. If so :
.Include(x => x.ApplicationsWithOverrideGroup.NestedProp)
or
.Include("ApplicationsWithOverrideGroup.NestedProp")
or
.Include($"{nameof(ApplicationsWithOverrideGroup)}.{nameof(NestedProp)}")

MakeAllPath Left(PP, InStrRev(PS, "\") - 1)

'
' loop through required folders
'
For LI = 1 To UBound(PathStrArray)
BuildPath = BuildPath & PathStrArray(LI) & "\"
If Dir(BuildPath, vbDirectory) = vbNullString Then MkDir BuildPath
Next LI
End If
' was already there

'MakeAllDir "K:\bil\herb\Jim"
'MakeAllDir "bil\joan\wat" ' default drive
Try this
link_to "+ Service", my_services_new_path(:account_id => acct.id)
it will pass the account_id as you want.

This is not an answer to the OP question but a toy example to illustrate the answer of @ShikharDua above which I found very useful.
While this fragment is trivial, in the actual data I had 1,000s of rows, and many columns, and I wished to be able to group by different columns and then perform the stats below for more than one taget column. So having a reliable method for building the data frame one row at a time was a great convenience. Thank you @ShikharDua !
import pandas as pd
BaseData = pd.DataFrame({ 'Customer' : ['Acme','Mega','Acme','Acme','Mega','Acme'],
'Territory' : ['West','East','South','West','East','South'],
'Product' : ['Econ','Luxe','Econ','Std','Std','Econ']})
BaseData
columns = ['Customer','Num Unique Products', 'List Unique Products']
rows_list=[]
for name, group in BaseData.groupby('Customer'):
RecordtoAdd={} #initialise an empty dict
RecordtoAdd.update({'Customer' : name}) #
RecordtoAdd.update({'Num Unique Products' : len(pd.unique(group['Product']))})
RecordtoAdd.update({'List Unique Products' : pd.unique(group['Product'])})
rows_list.append(RecordtoAdd)
AnalysedData = pd.DataFrame(rows_list)
print('Base Data : \n',BaseData,'\n\n Analysed Data : \n',AnalysedData)
This is my approach:
String[] columnNames = {"id", "Nome", "Sobrenome","Email"};
List<Student> students = _repo.getAll();
Object[][] data = new Object[students.size()][4];
int index = 0;
for(Student s : students) {
data[index][0] = s.getId();
data[index][1] = s.getFirstName();
data[index][2] = s.getLastName();
data[index][3] = s.getEmail();
index++;
}
DefaultTableModel model = new DefaultTableModel(data, columnNames);
table = new JTable(model);
INSERT
INTO Employee
(emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT '001', 'John Doe', '1 River Walk, Green Street', state_id, position_id, manager_id
FROM dual
JOIN state s
ON s.state_name = 'New York'
JOIN positions p
ON p.position_name = 'Sales Executive'
JOIN manager m
ON m.manager_name = 'Barry Green'
Note that but a single spelling mistake (or an extra space) will result in a non-match and nothing will be inserted.
Use this :
private string GetAlbumRSS(SyndicationItem album)
{
string url = "";
foreach (SyndicationElementExtension ext in album.ElementExtensions)
if (ext.OuterName == "itemRSS") url = ext.GetObject<string>();
return (url);
}
protected void Page_Load(object sender, EventArgs e)
{
string albumRSS;
string url = "http://www.SomeSite.com/rss?";
XmlReader r = XmlReader.Create(url);
SyndicationFeed albums = SyndicationFeed.Load(r);
r.Close();
foreach (SyndicationItem album in albums.Items)
{
cell.InnerHtml = cell.InnerHtml +string.Format("<br \'><a href='{0}'>{1}</a>", album.Links[0].Uri, album.Title.Text);
albumRSS = GetAlbumRSS(album);
}
}
You will have to annotate your service with @Service
since you have said I am using annotations for mapping
I think it comes from this line in your XML file:
<context:component-scan base-package="org.assessme.com.controller." />
Replace it by:
<context:component-scan base-package="org.assessme.com." />
It is because your Autowired service is not scanned by Spring since it is not in the right package.
Here's how I did it:
table.getSelectionModel().addListSelectionListener(new ListSelectionListener(){
public void valueChanged(ListSelectionEvent event) {
// do some actions here, for example
// print first column value from selected row
System.out.println(table.getValueAt(table.getSelectedRow(), 0).toString());
}
});
This code reacts on mouse click and item selection from keyboard.
Spring uses an special logic for resolving this kind of circular dependencies with singleton beans. But this won't apply to other scopes. There is no elegant way of breaking this circular dependency, but a clumsy option could be this one:
@Component("bean1")
@Scope("view")
public class Bean1 {
@Autowired
private Bean2 bean2;
@PostConstruct
public void init() {
bean2.setBean1(this);
}
}
@Component("bean2")
@Scope("view")
public class Bean2 {
private Bean1 bean1;
public void setBean1(Bean1 bean1) {
this.bean1 = bean1;
}
}
Anyway, circular dependencies are usually a symptom of bad design. You would think again if there is some better way of defining your class dependencies.
You can also do it with jQuery:
var options = ["1", "2", "3", "4", "5"];
$('#select').empty();
$.each(options, function(i, p) {
$('#select').append($('<option></option>').val(p).html(p));
});
Try like this:
if($user_sam -ne $NULL -and $user_case -ne $NULL)
Empty variables are $null
and then different from "" ([string]::empty
).
These both work fine for me...
<?php
$db = mysql_connect('localhost','user','pass');
mysql_select_db('test_db');
$stmt = "INSERT INTO `test` (`first`,`last`,`whenadded`) VALUES ".
"('{$first}','{$last}','NOW())";
$rslt = mysql_query($stmt);
$stmt = "INSERT INTO `users` (`first`,`last`,`whenadded`) VALUES ".
"('{$first}', '{$last}', CURRENT_TIMESTAMP)";
$rslt = mysql_query($stmt);
?>
Side note: mysql_query() is not the best way to connect to MySQL in current versions of PHP.
$("#MyTableData").on({
mouseenter: function(){
//stuff to do on mouse enter
$(this).css({'color':'red'});
},

$(this).css({'color':'blue'});
}},'tr');
What you've seen is what you get - and it's exactly what you asked for, here:
(ppc, c) => new { productproductcategory = ppc, category = c}
That's a lambda expression returning an anonymous type with those two properties.
In your CategorizedProducts, you just need to go via those properties:
CategorizedProducts catProducts = query.Select(
m => new {
ProdId = m.productproductcategory.product.Id,
CatId = m.category.CatId,
// other assignments
});
.hide{
visibility: hidden
}
<td class="hide"/>
Edit- Just for you
The difference between display and visibility is this.
"display": has many properties or values, but the ones you're focused on are "none" and "block". "none" is like a hide value, and "block" is like show. If you use the "none" value you will totally hide what ever html tag you have applied this css style. If you use "block" you will see the html tag and it's content. very simple.
"visibility": has many values, but we want to know more about the "hidden" and "visible" values. "hidden" will work in the same way as the "block" value for display, but this will hide tag and it's content, but it will not hide the phisical space of that tag. For example, if you have a couple of text lines, then and image (picture) and then a table with three columns and two rows with icons and text. Now if you apply the visibility css with the hidden value to the image, the image will disappear but the space the image was using will remaing in it's place, in other words, you will end with a big space (hole) between the text and the table. Now if you use the "visible" value your target tag and it's elements will be visible again.
I use this function:
function formatcell($data, $num, $fill=" ") {
$data = trim($data);
$data=str_replace(chr(13),' ',$data);
$data=str_replace(chr(10),' ',$data);
// translate UTF8 to English characters
$data = iconv('UTF-8', 'ASCII//TRANSLIT', $data);
$data = preg_replace("/[\'\"\^\~\`]/i", '', $data);
// fill it up with spaces
for ($i = strlen($data); $i < $num; $i++) {
$data .= $fill;
}
// limit string to num characters
$data = substr($data, 0, $num);
return $data;
}
echo formatcell("YES UTF8 String Zürich", 25, 'x'); //YES UTF8 String Zürichxxx
echo formatcell("NON UTF8 String Zurich", 25, 'x'); //NON UTF8 String Zurichxxx
Check out my function in my blog http://www.unexpectedit.com/php/php-handling-non-english-characters-utf8
When programming the NODEMCU card with the Arduino IDE, you need to customize it and you must have selected the correct card.
Open Arduino IDE and go to files and click on the preference in the Arduino IDE.
Add the following link to the Additional Manager URLS section: "http://arduino.esp8266.com/stable/package_esp8266com_index.json" and press the OK button.
Then click Tools> Board Manager. Type "ESP8266" in the text box to search and install the ESP8266 software for Arduino IDE.
You will be successful when you try to program again by selecting the NodeMCU card after these operations. I hope I could help.
This question already had a lot of answers. Unfortunately none worked for me. So for the sake of completenes I add what helped me:
I had multiple images with the same name - so I ordered them in sub folders. And I had the full path to the image file I wanted to show. With a full path imageNamed:
(as used in all solutions above) did not work and was the wrong method.
Instead I now use imageWithContentsOfFile:
like so:
self.myUIImage.image = [UIImage imageWithContentsOfFile:_currentWord.imageFileName];
Don't know, if anyone reads that far?
If so and this one helped you: please vote up. ;-)
I had this same problem and had to refer to the php manual which told me the mysql and mysqli extensions require libmysql.dll to load. I searched for it under C:\windows\system32 (windows 7) and could not find, so I downloaded it here and placed it in my C:\windows\system32. I restarted Apache and everything worked fine. Took me 3 days to figure out, hope it helps.
This happened to me when I tried to update a table whose size on disk was bigger than the available disk space. The solution for me was simply to increase the available disk space.
$(document).on('click', '#submitBtn', function(e){
e.preventDefault();
e.stopImmediatePropagation();
var form = $("#myForm").closest("form");
var formData = new FormData(form[0]);
$.ajax({
type: "POST",
data: formData,
dataType: "json",
url: form.attr('action'),
processData: false,
contentType: false,
success: function(data) {
alert('Sucess! Form data posted with file type of input also!');
}
)};});
By making use of new FormData()
and setting processData: false, contentType:false
in ajax call submission of form with file input worked for me
Using above code I am able to submit form data with file field also through Ajax
$(document).ready ->
$("a[href^='#']").click ->
$(document.body).animate
scrollTop: $($(this).attr("href")).offset().top, 1000
I realise that's not the case here but it might help someone.
Double-check you didn't create the conf file in /etc/apache2/sites-enabled by mistake. You get the same error.
IN completion to above answers, you can also customize your fallbacks for each async call you do, so that each call to the generic ASYNC method will populate different data, depending on the onTaskDone stuff you put there.
Main.FragmentCallback FC= new Main.FragmentCallback(){
@Override
public void onTaskDone(String results) {
localText.setText(results); //example TextView
}
};
new API_CALL(this.getApplicationContext(), "GET",FC).execute("&Books=" + Main.Books + "&args=" + profile_id);
Remind: I used interface on the main activity thats where "Main" comes, like this:
public interface FragmentCallback {
public void onTaskDone(String results);
}
My API post execute looks like this:
@Override
protected void onPostExecute(String results) {
Log.i("TASK Result", results);
mFragmentCallback.onTaskDone(results);
}
The API constructor looks like this:
class API_CALL extends AsyncTask<String,Void,String> {
private Main.FragmentCallback mFragmentCallback;
private Context act;
private String method;
public API_CALL(Context ctx, String api_method,Main.FragmentCallback fragmentCallback) {
act=ctx;
method=api_method;
mFragmentCallback = fragmentCallback;
}
I had the same problem and I fixed it with:
<div id="container" style="width: 100%; height: 100%; position:absolute"></div>
The chart fits perfect to the browser even if I resize it. You can change the percentage according to your needs.
While looking at the same problem, I found an example
<style type="text/css">
#topright {
position: absolute;
right: 0;
top: 0;
display: block;
height: 125px;
width: 125px;
background: url(TRbanner.gif) no-repeat;
text-indent: -999em;
text-decoration: none;
}
</style>
<a id="topright" href="#" title="TopRight">Top Right Link Text</a>
The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)
I was able to solve "ORA-00604: error" by Droping with purge.
DROP TABLE tablename PURGE
{=FIND("cell I want to search","list of words I want to search for")}
{=SUM(FIND($A$1:$A$100&"|";A3))}
this ensures spreadsheet will compare strings like "cellvlaue|" againts "pattern1|", "pattern2|" etc. which sorts out conflicts like pattern1="newly added", pattern2="added" (sum of all cells matching "added" would be too high, including the target values for cells matching "newly added", which would be a logical error)This works:
public class Split
{
public static void main(String...args)
{
String a = "%abcdef&Ghijk%xyz";
String b[] = a.split("%", 2);
System.out.println("Value = "+b[1]);
}
}
The purpose is that you can give a default value if the key is not found, which is very useful
dictionary.get("Name",'harry')
private boolean containsIgnoreCase(List<String> list, String soughtFor) {
for (String current : list) {
if (current.equalsIgnoreCase(soughtFor)) {
return true;
}
}
return false;
}
The second function should have:
var value = document.getElementById(id).value;
Then they are basically the same function.
volatile is a field modifier, while synchronized modifies code blocks and methods. So we can specify three variations of a simple accessor using those two keywords:
int i1; int geti1() {return i1;} volatile int i2; int geti2() {return i2;} int i3; synchronized int geti3() {return i3;}
geti1()
accesses the value currently stored ini1
in the current thread. Threads can have local copies of variables, and the data does not have to be the same as the data held in other threads.In particular, another thread may have updatedi1
in it's thread, but the value in the current thread could be different from that updated value. In fact Java has the idea of a "main" memory, and this is the memory that holds the current "correct" value for variables. Threads can have their own copy of data for variables, and the thread copy can be different from the "main" memory. So in fact, it is possible for the "main" memory to have a value of 1 fori1
, for thread1 to have a value of 2 fori1
and for thread2 to have a value of 3 fori1
if thread1 and thread2 have both updated i1 but those updated value has not yet been propagated to "main" memory or other threads.On the other hand,
geti2()
effectively accesses the value ofi2
from "main" memory. A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory. Effectively, a variable declared volatile must have it's data synchronized across all threads, so that whenever you access or update the variable in any thread, all other threads immediately see the same value. Generally volatile variables have a higher access and update overhead than "plain" variables. Generally threads are allowed to have their own copy of data is for better efficiency.There are two differences between volitile and synchronized.
Firstly synchronized obtains and releases locks on monitors which can force only one thread at a time to execute a code block. That's the fairly well known aspect to synchronized. But synchronized also synchronizes memory. In fact synchronized synchronizes the whole of thread memory with "main" memory. So executing
geti3()
does the following:
- The thread acquires the lock on the monitor for object this .
- The thread memory flushes all its variables, i.e. it has all of its variables effectively read from "main" memory .
- The code block is executed (in this case setting the return value to the current value of i3, which may have just been reset from "main" memory).
- (Any changes to variables would normally now be written out to "main" memory, but for geti3() we have no changes.)
- The thread releases the lock on the monitor for object this.
So where volatile only synchronizes the value of one variable between thread memory and "main" memory, synchronized synchronizes the value of all variables between thread memory and "main" memory, and locks and releases a monitor to boot. Clearly synchronized is likely to have more overhead than volatile.

simply use..
location.reload(true/false);
If false, the page will be reloaded from cache, else from the server.
var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current date

point 2 and 3 are using in your jquery code...
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.
#include <sys/socket.h>
#include <sys/ioctl.h>

{
struct ifreq s;
int fd = socket(PF_INET, SOCK_DGRAM, IPPROTO_IP);
strcpy(s.ifr_name, "eth0");
if (0 == ioctl(fd, SIOCGIFHWADDR, &s)) {
int i;
for (i = 0; i < 6; ++i)
printf(" %02x", (unsigned char) s.ifr_addr.sa_data[i]);

Similar to Ghommey's answer, but this also supports old versions of IE and Firefox.
window.onbeforeunload = function (e) {
var message = "Your confirmation message goes here.",
e = e || window.event;
// For IE and Firefox
if (e) {
e.returnValue = message;
}
// For Safari
return message;
};
On .Net Core 3.1 we just need to do these:
static void Main(string[] args)
{
var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
}
Using SeriLog will look like:
using Microsoft.Extensions.Configuration;
using Serilog;
using System;
namespace yournamespace
{
class Program
{
static void Main(string[] args)
{
var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(configuration).CreateLogger();
try
{
Log.Information("Starting Program.");
}
catch (Exception ex)
{
Log.Fatal(ex, "Program terminated unexpectedly.");
return;
}
finally
{
Log.CloseAndFlush();
}
}
}
}
And the Serilog appsetings.json section for generating one file daily will look like:
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"System": "Warning"
}
},
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "C:\\Logs\\Program.json",
"rollingInterval": "Day",
"formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact"
}
}
]
}
This:
\d+
should work
Edit, no clue why I added the "+", without it works just as fine.

For html encoding, there's cgi.escape from the standard library:
>> help(cgi.escape)
cgi.escape = escape(s, quote=None)
Replace special characters "&", "<" and ">" to HTML-safe sequences.
If the optional flag quote is true, the quotation mark character (")
is also translated.
For html decoding, I use the following:
import re
from htmlentitydefs import name2codepoint
# for some reason, python 2.5.2 doesn't have this one (apostrophe)
name2codepoint['#39'] = 39
def unescape(s):
"unescape HTML code refs; c.f. http://wiki.python.org/moin/EscapingHtml"
return re.sub('&(%s);' % '|'.join(name2codepoint),
lambda m: unichr(name2codepoint[m.group(1)]), s)
For anything more complicated, I use BeautifulSoup.
I'd do this one of two ways. Since you're setting your start and end dates in your t-sql code, i wouldn't ask for parameters in the stored proc
Option 1
Create Procedure [Test] AS
DECLARE @StartDate varchar(10)
DECLARE @EndDate varchar(10)
Set @StartDate = '201620' --Define start YearWeek
Set @EndDate = (SELECT CAST(DATEPART(YEAR,getdate()) AS varchar(4)) + CAST(DATEPART(WEEK,getdate())-1 AS varchar(2)))
SELECT
*
FROM
(SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)
Option 2
Create Procedure [Test] @StartDate varchar(10),@EndDate varchar(10) AS
SELECT
*
FROM
(SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)
Then run exec test '2016-01-01','2016-01-25'
Inside of VBS you can access parameters with
Wscript.Arguments(0)
Wscript.Arguments(1)
and so on. The number of parameter:
Wscript.Arguments.Count
I think what you are trying to achieve can simply be done like this :
While you are compiling the coffeescript, use the "-b" parameter.
-b
/ --bare
Compile the JavaScript without the top-level function safety wrapper.
So something like this : coffee -b --compile somefile.coffee whatever.js
This will output your code just like in the CoffeeScript.org site.
It seems more elegant combining two classes. You can drop two-lines
class if only one row need see:
.ellipse {_x000D_

display:inline-block;_x000D_
overflow: hidden;_x000D_
text-overflow: ellipsis;_x000D_
}_x000D_
.two-lines {_x000D_

display: -webkit-box;_x000D_
-webkit-box-orient: vertical;_x000D_
white-space: normal;_x000D_
}_x000D_
.width{_x000D_

u can try this code, fastest way to get prime with the less loop posible a number like 1000 will get less than 15 loops
def divisors(integer):
result = []
i = 2
j = integer/2
while(i <= j):
if integer % i == 0:
result.append(i)
if i != integer//i:
result.append(integer//i)
i += 1
j = integer//i
if len(result) > 0:
return sorted(result)
else:
return f"{integer} is prime"
print(divisors(1827))
print(divisors(1025))
print(divisors(27))
See section Attributes from documentation on directives.
observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.
You can use var a= if (a) b else c
in place of the ternary operator.
Another good concept of kotlin is Elvis operater. You don't need to check null every time.
val l = b?.length ?: -1
This will return length if b is not null otherwise it executes right side statement.
My solution was to not use the id of an anchor element: <a id='star_wars'>Place to jump to</a>
. Apparently blazor and other spa frameworks have issues jumping to anchors on the same page. To get around that I had to use document.getElementById('star_wars')
. However this didn't work until I put the id in a paragraph element instead: <p id='star_wars'>Some paragraph<p>
.
Example using bootstrap:
<button class="btn btn-link" onclick="document.getElementById('star_wars').scrollIntoView({behavior:'smooth'})">Star Wars</button>
... lots of other text
<p id="star_wars">Star Wars is an American epic...</p>

JPA doesn't offer any support for derived property so you'll have to use a provider specific extension. As you mentioned, @Formula
is perfect for this when using Hibernate. You can use an SQL fragment:
@Formula("PRICE*1.155")
private float finalPrice;
Or even complex queries on other tables:
@Formula("(select min(o.creation_date) from Orders o where o.customer_id = id)")
private Date firstOrderDate;
Where id
is the id
of the current entity.
The following blog post is worth the read: Hibernate Derived Properties - Performance and Portability.
Without more details, I can't give a more precise answer but the above link should be helpful.
import operator
sortedlist = sorted(reader, key=operator.itemgetter(3), reverse=True)
or use lambda
sortedlist = sorted(reader, key=lambda row: row[3], reverse=True)
To inspect files, run docker run -it <image> /bin/sh
to get an interactive terminal. The list of images can be obtained by docker images
. In contrary to docker exec
this solution works also in case when an image doesn't start (or quits immediately after running).
You can P/Invoke down to the Win32 GetAsyncKeyState to test any key on the keyboard.
You can pass in values from the Keys enum (e.g. Keys.Shift) to this function, so it only requires a couple of lines of code to add it.

It worked for me.
Since JSR 305 (whose goal was to standardize @NonNull
and @Nullable
) has been dormant for several years, I'm afraid there is no good answer. All we can do is to find a pragmatic solution and mine is as follows:
From a purely stylistic standpoint I would like to avoid any reference to IDE, framework or any toolkit except Java itself.
This rules out:
android.support.annotation
edu.umd.cs.findbugs.annotations
org.eclipse.jdt.annotation
org.jetbrains.annotations
org.checkerframework.checker.nullness.qual
lombok.NonNull
Which leaves us with either javax.validation.constraints
or javax.annotation
.
The former comes with JEE. If this is better than javax.annotation
, which might come eventually with JSE or never at all, is a matter of debate.
I personally prefer javax.annotation
because I wouldn't like the JEE dependency.
This leaves us with
javax.annotation
which is also the shortest one.
There is only one syntax which would even be better: java.annotation.Nullable
. As other packages graduated
from javax
to java
in the past, the javax.annotation would
be a step in the right direction.
I was hoping that they all have basically the same trivial implementation, but a detailed analysis showed that this is not true.
First for the similarities:
The @NonNull
annotations all have the line
public @interface NonNull {}
except for
org.jetbrains.annotations
which calls it @NotNull
and has a trivial implementationjavax.annotation
which has a longer implementationjavax.validation.constraints
which also calls it @NotNull
and has an implementationThe @Nullable
annotations all have the line
public @interface Nullable {}
except for (again) the org.jetbrains.annotations
with their trivial implementation.
For the differences:
A striking one is that
javax.annotation
javax.validation.constraints
org.checkerframework.checker.nullness.qual
all have runtime annotations (@Retention(RUNTIME)
), while
android.support.annotation
edu.umd.cs.findbugs.annotations
org.eclipse.jdt.annotation
org.jetbrains.annotations
are only compile time (@Retention(CLASS)
).
As described in this SO answer the impact of runtime annotations is smaller than one might think, but they have the benefit of enabling tools to do runtime checks in addition to the compile time ones.
Another important difference is where in the code the annotations can be used. There are two different approaches. Some packages use JLS 9.6.4.1 style contexts. The following table gives an overview:
FIELD METHOD PARAMETER LOCAL_VARIABLE android.support.annotation X X X edu.umd.cs.findbugs.annotations X X X X org.jetbrains.annotation X X X X lombok X X X X javax.validation.constraints X X X
org.eclipse.jdt.annotation
, javax.annotation
and org.checkerframework.checker.nullness.qual
use the contexts defined in
JLS 4.11, which is in my opinion the right way to do it.
This leaves us with
javax.annotation
org.checkerframework.checker.nullness.qual
in this round.
To help you to compare further details yourself I list the code of every annotation below.
To make comparison easier I removed comments, imports and the @Documented
annotation.
(they all had @Documented
except for the classes from the Android package).
I reordered the lines and @Target
fields and normalized the qualifications.
package android.support.annotation;
@Retention(CLASS)
@Target({FIELD, METHOD, PARAMETER})
public @interface NonNull {}
package edu.umd.cs.findbugs.annotations;
@Retention(CLASS)
@Target({FIELD, METHOD, PARAMETER, LOCAL_VARIABLE})
public @interface NonNull {}
package org.eclipse.jdt.annotation;
@Retention(CLASS)
@Target({ TYPE_USE })
public @interface NonNull {}
package org.jetbrains.annotations;
@Retention(CLASS)
@Target({FIELD, METHOD, PARAMETER, LOCAL_VARIABLE})
public @interface NotNull {String value() default "";}
package javax.annotation;
@TypeQualifier
@Retention(RUNTIME)
public @interface Nonnull {
When when() default When.ALWAYS;
static class Checker implements TypeQualifierValidator<Nonnull> {
public When forConstantValue(Nonnull qualifierqualifierArgument,
Object value) {
if (value == null)
return When.NEVER;
return When.ALWAYS;
}
}
}
package org.checkerframework.checker.nullness.qual;
@Retention(RUNTIME)
@Target({TYPE_USE, TYPE_PARAMETER})
@SubtypeOf(MonotonicNonNull.class)
@ImplicitFor(
types = {
TypeKind.PACKAGE,
TypeKind.INT,
TypeKind.BOOLEAN,
TypeKind.CHAR,
TypeKind.DOUBLE,
TypeKind.FLOAT,
TypeKind.LONG,
TypeKind.SHORT,
TypeKind.BYTE
},
literals = {LiteralKind.STRING}
)
@DefaultQualifierInHierarchy
@DefaultFor({TypeUseLocation.EXCEPTION_PARAMETER})
@DefaultInUncheckedCodeFor({TypeUseLocation.PARAMETER, TypeUseLocation.LOWER_BOUND})
public @interface NonNull {}
For completeness, here are the @Nullable
implementations:
package android.support.annotation;
@Retention(CLASS)
@Target({METHOD, PARAMETER, FIELD})
public @interface Nullable {}
package edu.umd.cs.findbugs.annotations;
@Target({FIELD, METHOD, PARAMETER, LOCAL_VARIABLE})
@Retention(CLASS)
public @interface Nullable {}
package org.eclipse.jdt.annotation;
@Retention(CLASS)
@Target({ TYPE_USE })
public @interface Nullable {}
package org.jetbrains.annotations;
@Retention(CLASS)
@Target({FIELD, METHOD, PARAMETER, LOCAL_VARIABLE})
public @interface Nullable {String value() default "";}
package javax.annotation;
@TypeQualifierNickname
@Nonnull(when = When.UNKNOWN)
@Retention(RUNTIME)
public @interface Nullable {}
package org.checkerframework.checker.nullness.qual;
@Retention(RUNTIME)
@Target({TYPE_USE, TYPE_PARAMETER})
@SubtypeOf({})
@ImplicitFor(
literals = {LiteralKind.NULL},
typeNames = {java.lang.Void.class}
)
@DefaultInUncheckedCodeFor({TypeUseLocation.RETURN, TypeUseLocation.UPPER_BOUND})
public @interface Nullable {}
The following two packages have no @Nullable
, so I list them separately; Lombok has a pretty boring @NonNull
.
In javax.validation.constraints
the @NonNull
is actually a @NotNull
and it has a longish implementation.
package lombok;
@Retention(CLASS)
@Target({FIELD, METHOD, PARAMETER, LOCAL_VARIABLE})
public @interface NonNull {}
package javax.validation.constraints;
@Retention(RUNTIME)
@Target({ FIELD, METHOD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER })
@Constraint(validatedBy = {})
public @interface NotNull {
String message() default "{javax.validation.constraints.NotNull.message}";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default {};
@Target({ METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER })
@Retention(RUNTIME)
@Documented
@interface List {
NotNull[] value();
}
}
From my experience, javax.annotation
is at least supported by Eclipse and the Checker Framework out of the box.
My ideal annotation would be the java.annotation
syntax with the Checker Framework implementation.
If you don't intend to use the Checker Framework the javax.annotation
(JSR-305) is still your best bet for the time being.
If you are willing to buy into the Checker Framework just use
their org.checkerframework.checker.nullness.qual
.

If you're getting an address mismatch error, just allow address mismatches:
I recommend using the short ' instead of ". If you do so, you wont longer have to escape the double quote (\").
In that case you would write
echo '<a href="http://www.whatever.com/'. $param .'">Click Here</a>';
But look onto nicolaas' answer "what you really should do" to learn how to produce cleaner code.
so not sure if this answers your question but the indexOf the items you are adding keep returning -1. Not to familiar with js but it appears the items do that because they are not in the array yet. I made a jsfiddle of a little modified code for you.
this.items = [];
add(1);
add(2);
add(3);
document.write("added items to array");
document.write("<br>");
function add(item) {
//document.write(this.items.indexOf(item));
if(this.items.indexOf(item) <= -1) {
this.items.push(item);
//document.write("Hello World!");
}
}
document.write("array is : " + this.items);
It's a pity to use .NET and not use collections and lambda to save your time and code lines This is an example of how this works: Transform yourDataTable to Enumerable, filter it if you want , according a "FILTER_ROWS_FIELD" column, and if you want, group your data by a "A_GROUP_BY_FIELD". Then get the count, the sum, or whatever you wish. If you want a count and a sum without grouby don't group the data
var groupedData = from b in yourDataTable.AsEnumerable().Where(r=>r.Field<int>("FILTER_ROWS_FIELD").Equals(9999))
group b by b.Field<string>("A_GROUP_BY_FIELD") into g
select new
{
tag = g.Key,
count = g.Count(),
sum = g.Sum(c => c.Field<double>("rvMoney"))
};
Here is a summary.
escape() will not encode @ * _ + - . /
Do not use it.
encodeURI() will not encode A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #
Use it when your input is a complete URL like 'https://searchexample.com/search?q=wiki'
const queryStr = encodeURIComponent(someString)
as @chepner says in his comment you are comparing $i to a fixed string.
To expand and rectify the situation you should use [[ ]] with the regex operator =~
eg:
for i in $(ls);do
if [[ $i =~ .*\.java$ ]];then
echo "I want to do something with the file $i"
fi
done
the regex to the right of =~ is tested against the value of the left hand operator and should not be quoted, ( quoted will not error but will compare against a fixed string and so will most likely fail"
but @chepner 's answer above using glob is a much more efficient mechanism.
Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.
About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003
Introduction to importing and exporting data -- Applies to: Microsoft Access 2010
Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.
<meta charset='utf-8'> overrides the apache default charset (cf /etc/apache2/conf.d/charset)
If this is not enough, then you probably created your original file with iso-8859-1 encoding character set. You have to convert it to the proper character set:
iconv -f ISO-8859-1 -t UTF-8 source_file.php -o new file.php
You can use the TextView for the same purpose, But if you want to use the same with the ImageView then you have to create a class and extends the ImageView then use onDraw() method to paint the text on to the canvas. for more details visit to http://developer.android.com/reference/android/graphics/Canvas.html
Also have a look at BootBox, it's really simple to show alerts and confirm boxes in a bootstrap modal. http://bootboxjs.com/
The implementation is as easy as this:
Normal alert:
bootbox.alert("Hello world!");
Confirm:
bootbox.confirm("Are you sure?", function(result) {
Example.show("Confirm result: "+result);
});
Promt:
bootbox.prompt("What is your name?", function(result) {
if (result === null) {
Example.show("Prompt dismissed");
} else {
Example.show("Hi <b>"+result+"</b>");
}
});
And even custom:
bootbox.dialog("I am a custom dialog", [{
"label" : "Success!",
"class" : "btn-success",
"callback": function() {
Example.show("great success");
}
}, {
"label" : "Danger!",
"class" : "btn-danger",
"callback": function() {
Example.show("uh oh, look out!");
}
}, {
"label" : "Click ME!",
"class" : "btn-primary",
"callback": function() {
Example.show("Primary button");
}
}, {
"label" : "Just a button..."
}]);
Step 1:-
string[] Ids = new string[] { "3", "6", "14" };
string IdsSP = string.Format("'|{0}|'", string.Join("|", Ids));
Step 2:-
@CurrentShipmentStatusIdArray [nvarchar](255) = NULL
Step 3:-
Where @CurrentShipmentStatusIdArray is null or @CurrentShipmentStatusIdArray LIKE '%|' + convert(nvarchar,Shipments.CurrentShipmentStatusId) + '|%'
or
Where @CurrentShipmentStatusIdArray is null or @CurrentShipmentStatusIdArray LIKE '%|' + Shipments.CurrentShipmentStatusId+ '|%'
You can use WordPress predefined function to add script file to WordPress plugin.
wp_enqueue_script( 'script', plugins_url('js/demo_script.js', __FILE__), array('jquery'));
Look at the post which helps you to understand that how easily you can implement jQuery and CSS in WordPress plugin.
It's better, if you use two div containers in HTML .
As Shown Below:
HTML:
<div id="container1">
<div id="container2">
// Content here
</div>
</div>
CSS:
#container1{
height: 100%;
width: 100%;
overflow: hidden;
}
#container2{
height: 100%;
width: 100%;
overflow: auto;
padding-right: 20px;
}
There is nothing wrong with your code. It's the NBC.com doing tricks on you. When NBC.com decides that your browser is not capable of displaying PDF, it simply sends back a webpage regardless what you are requesting, even if it doesn't exist.
You need to trick it back by telling it your browser is capable, something like,
conn.setRequestProperty("User-Agent",
"Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.13) Gecko/2009073021 Firefox/3.0.13");
Well, you can hide it, by removing the entire system menu:
private const int WS_SYSMENU = 0x80000;
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.Style &= ~WS_SYSMENU;
return cp;
}
}
Of course, doing so removes the minimize and maximize buttons.
If you keep the system menu but remove the close item then the close button remains but is disabled.
The final alternative is to paint the non-client area yourself. That's pretty hard to get right.
Alternatively you can create such a function:
function implode_with_quotes(array $data)
{
return sprintf("'%s'", implode("', '", $data));
}
Option 1:
NSString *haystack = @"value:hello World:value";
NSString *haystackPrefix = @"value:";
NSString *haystackSuffix = @":value";
NSRange needleRange = NSMakeRange(haystackPrefix.length,
haystack.length - haystackPrefix.length - haystackSuffix.length);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle); // -> "hello World"
Option 2:
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^value:(.+?):value$" options:0 error:nil];
NSTextCheckingResult *match = [regex firstMatchInString:haystack options:NSAnchoredSearch range:NSMakeRange(0, haystack.length)];
NSRange needleRange = [match rangeAtIndex: 1];
NSString *needle = [haystack substringWithRange:needleRange];
This one might be a bit over the top for your rather trivial case though.
Option 3:
NSString *needle = [haystack componentsSeparatedByString:@":"][1];
This one creates three temporary strings and an array while splitting.
All snippets assume that what's searched for is actually contained in the string.
String clsName = "Ex"; // use fully qualified name
Class cls = Class.forName(clsName);
Object clsInstance = (Object) cls.newInstance();

system("mkdir -p /tmp/a/b/c")
is the shortest way I can think of (in terms of the length of code, not necessarily execution time).
It's not cross-platform but will work under Linux.
I've been knocking other people's (@datayeah & Vithani Ravi) solutions a bit hard here, so I thought I'd share my own attempt[s] at solving this variable screen density scaling problem or shut up. So I approach this problem from a solid/fixed foundation: I base all my scaling off a fixed (immutable) ratio of 2:1 (height:width). I have a helper class "McGyver" that does all the heavy lifting (and useful code finessing) across my app. This "McGyver" class contains only static methods and static constant class members.
RATIO SCALING METHOD: I scale both width & height independently based on the 2:1 Aspect Ratio. I take width & height input values and divide each by the width & height constants and finally compute an adjustment factor by which to scale the respective width & height input values. The actual code looks as follows:
import 'dart:math';
import 'package:flutter/material.dart';
class McGyver {
static const double _fixedWidth = 410; // Set to an Aspect Ratio of 2:1 (height:width)
static const double _fixedHeight = 820; // Set to an Aspect Ratio of 2:1 (height:width)
// Useful rounding method (@andyw solution -> https://stackoverflow.com/questions/28419255/how-do-you-round-a-double-in-dart-to-a-given-degree-of-precision-after-the-decim/53500405#53500405)
static double roundToDecimals(double val, int decimalPlaces){
double mod = pow(10.0, decimalPlaces);
return ((val * mod).round().toDouble() / mod);
}
// The 'Ratio-Scaled' Widget method (takes any generic widget and returns a "Ratio-Scaled Widget" - "rsWidget")
static Widget rsWidget(BuildContext ctx, Widget inWidget, double percWidth, double percHeight) {
// ---------------------------------------------------------------------------------------------- //
// INFO: Ratio-Scaled "SizedBox" Widget - Scaling based on device's height & width at 2:1 ratio. //
// ---------------------------------------------------------------------------------------------- //
final int _decPlaces = 5;
final double _fixedWidth = McGyver._fixedWidth;
final double _fixedHeight = McGyver._fixedHeight;
Size _scrnSize = MediaQuery.of(ctx).size; // Extracts Device Screen Parameters.
double _scrnWidth = _scrnSize.width.floorToDouble(); // Extracts Device Screen maximum width.
double _scrnHeight = _scrnSize.height.floorToDouble(); // Extracts Device Screen maximum height.
double _rsWidth = 0;
if (_scrnWidth == _fixedWidth) { // If input width matches fixedWidth then do normal scaling.
_rsWidth = McGyver.roundToDecimals((_scrnWidth * (percWidth / 100)), _decPlaces);
} else { // If input width !match fixedWidth then do adjustment factor scaling.
double _scaleRatioWidth = McGyver.roundToDecimals((_scrnWidth / _fixedWidth), _decPlaces);
double _scalerWidth = ((percWidth + log(percWidth + 1)) * pow(1, _scaleRatioWidth)) / 100;
_rsWidth = McGyver.roundToDecimals((_scrnWidth * _scalerWidth), _decPlaces);
}
double _rsHeight = 0;
if (_scrnHeight == _fixedHeight) { // If input height matches fixedHeight then do normal scaling.
_rsHeight = McGyver.roundToDecimals((_scrnHeight * (percHeight / 100)), _decPlaces);
} else { // If input height !match fixedHeight then do adjustment factor scaling.
double _scaleRatioHeight = McGyver.roundToDecimals((_scrnHeight / _fixedHeight), _decPlaces);
double _scalerHeight = ((percHeight + log(percHeight + 1)) * pow(1, _scaleRatioHeight)) / 100;
_rsHeight = McGyver.roundToDecimals((_scrnHeight * _scalerHeight), _decPlaces);
}
// Finally, hand over Ratio-Scaled "SizedBox" widget to method call.
return SizedBox(
width: _rsWidth,
height: _rsHeight,
child: inWidget,
);
}
}
... ... ...
Then you would individually scale your widgets (which for my perfectionist disease is ALL of my UI) with a simple static call to the "rsWidget()" method as follows:
// Step 1: Define your widget however you like (this widget will be supplied as the "inWidget" arg to the "rsWidget" method in Step 2)...
Widget _btnLogin = RaisedButton(color: Colors.blue, elevation: 9.0,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(McGyver.rsDouble(context, ScaleType.width, 2.5))),
child: McGyver.rsText(context, "LOGIN", percFontSize: EzdFonts.button2_5, textColor: Colors.white, fWeight: FontWeight.bold),
onPressed: () { _onTapBtnLogin(_tecUsrId.text, _tecUsrPass.text); }, );
// Step 2: Scale your widget by calling the static "rsWidget" method...
McGyver.rsWidget(context, _btnLogin, 34.5, 10.0) // ...and Bob's your uncle!!
The cool thing is that the "rsWidget()" method returns a widget!! So you can either assign the scaled widget to another variable like _rsBtnLogin
for use all over the place - or you could simply use the full McGyver.rsWidget()
method call in-place inside your build()
method (exactly how you need it to be positioned in the widget tree) and it will work perfectly as it should.
For those more astute coders: you will have noticed that I used two additional ratio-scaled methods McGyver.rsText()
and McGyver.rsDouble()
(not defined in the code above) in my RaisedButton()
- so I basically go crazy with this scaling stuff...because I demand my apps to be absolutely pixel perfect at any scale or screen density!! I ratio-scale my ints, doubles, padding, text (everything that requires UI consistency across devices). I scale my texts based on width only, but specify which axis to use for all other scaling (as was done with the ScaleType.width
enum used for the McGyver.rsDouble()
call in the code example above).
I know this is crazy - and is a lot of work to do on the main thread - but I am hoping somebody will see my attempt here and help me find a better (more light-weight) solution to my screen density 1:1 scaling nightmares.
I have a simpler solution. In your destination page (irc_online.php) add an auto-refresh tag in the header.
Add the following to your Gemfile
ruby '2.3.0'
You convert the hex string to a byte array.
public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
.Where(x => x % 2 == 0)
.Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
.ToArray();
}

And then use WriteAllBytes to write to the file system.
Your problem is that you are relying on the browser to resize your images. Browsers have notoriously poor image scaling algorithms, which will cause the ugly pixelization.
You should resize your images in a graphics program first before you use them on the webpage.
Also, you have a spelling mistake: it should say moz-crisp-edges; however, that won't help you in your case (because that resizing algorithm won't give you a high quality resize: https://developer.mozilla.org/En/CSS/Image-rendering)
The answer I was looking for is at https://unix.stackexchange.com/a/9557/114862.
Using the
-c
flag when the local file is of greater or equal size to the server version will avoid re-downloading.
The mouseenter event differs from mouseover in the way it handles event bubbling. The mouseenter event, only triggers its handler when the mouse enters the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseenter/
The mouseleave event differs from mouseout in the way it handles event bubbling. The mouseleave event, only triggers its handler when the mouse leaves the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseleave/
NOTE : This solution is broken in iOS 8. I will post new solution ASAP.
I am going to answer here using storyboard but it is also possible without storyboard.
Init: Create two UIViewController
in storyboard.
FirstViewController
which is normal and SecondViewController
which will be the popup.
Modal Segue: Put UIButton
in FirstViewController and create a segue on this UIButton
to SecondViewController
as modal segue.
Make Transparent: Now select UIView
(UIView
Which is created by default with UIViewController
) of SecondViewController
and change its background color to clear color.
Make background Dim: Add an UIImageView
in SecondViewController
which covers whole screen and sets its image to some dimmed semi transparent image. You can get a sample from here : UIAlertView
Background Image
Display Design: Now add an UIView
and make any kind of design you want to show. Here is a screenshot of my storyboard
SecondViewController
as popup to ask username and passwordImportant: Now that main step. We want that SecondViewController
doesn't hide FirstViewController completely. We have set clear color but this is not enough. By default it adds black behind model presentation so we have to add one line of code in viewDidLoad of FirstViewController
. You can add it at another place also but it should run before segue.
[self setModalPresentationStyle:UIModalPresentationCurrentContext];
Dismiss: When to dismiss depends on your use case. This is a modal presentation so to dismiss we do what we do for modal presentation:
[self dismissViewControllerAnimated:YES completion:Nil];
Thats all.....
Any kind of suggestion and comment are welcome.
Demo : You can get demo source project from Here : Popup Demo
NEW : Someone have done very nice job on this concept : MZFormSheetController
New : I found one more code to get this kind of function : KLCPopup
iOS 8 Update : I made this method to work with both iOS 7 and iOS 8
+ (void)setPresentationStyleForSelfController:(UIViewController *)selfController presentingController:(UIViewController *)presentingController
{
if (iOSVersion >= 8.0)
{
presentingController.providesPresentationContextTransitionStyle = YES;
presentingController.definesPresentationContext = YES;
[presentingController setModalPresentationStyle:UIModalPresentationOverCurrentContext];
}
else
{
[selfController setModalPresentationStyle:UIModalPresentationCurrentContext];
[selfController.navigationController setModalPresentationStyle:UIModalPresentationCurrentContext];
}
}
Can use this method inside prepareForSegue deligate like this
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
PopUpViewController *popup = segue.destinationViewController;
[self setPresentationStyleForSelfController:self presentingController:popup]
}
My opinion is C# and ASP.NET would be the best of the three for development that is web biased.
I doubt anyone writes new web apps in C or C++ anymore. It was done 10 years ago, and there's likely a lot of legacy code still in use, but they're not particularly well suited, there doesn't appear to be as much (ongoing) tool support, and they probably have a small active community that does web development (except perhaps for web server development). I wrote many website C++ COM objects back in the day, but C# is far more productive that there's no compelling reason to code C or C++ (in this context) unless you need to.
I do still write C++ if necessary, but it's typically for a small problem domain. e.g. communicating from C# via P/Invoke to old C-style dll's - doing some things that are downright clumsy in C# were a breeze to create a C++ COM object as a bridge.
The nice thing with C# is that you can also easily transfer into writing Windows and Console apps and stay in C#. With Mono you're also not limited to Windows (although you may be limited to which libraries you use).
Anyways this is all from a web-biased perspective. If you asked about embedded devices I'd say C or C++. You could argue none of these are suited for web development, but C#/ASP.NET is pretty slick, it works well, there are heaps of online resources, a huge community, and free dev tools.
So from a real-world perspective, picking only one of C#, C++ and C as requested, as a general rule, you're better to stick with C#.
READ AT LEAST THE FIRST PARA HERE!
I know this is 3 years too late, but Matt's (accepted) answer is incomplete and will eventually get you into trouble. The key here is that, if you choose to use multipart/form-data
, the boundary must not appear in the file data that the server eventually receives.
This is not a problem for application/x-www-form-urlencoded
, because there is no boundary. x-www-form-urlencoded
can also always handle binary data, by the simple expedient of turning one arbitrary byte into three 7BIT
bytes. Inefficient, but it works (and note that the comment about not being able to send filenames as well as binary data is incorrect; you just send it as another key/value pair).
The problem with multipart/form-data
is that the boundary separator must not be present in the file data (see RFC 2388; section 5.2 also includes a rather lame excuse for not having a proper aggregate MIME type that avoids this problem).
So, at first sight, multipart/form-data
is of no value whatsoever in any file upload, binary or otherwise. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.
The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64
(do not use raw binary). In base64 3 arbitrary bytes are encoded into four 7-bit characters, where the output character set is [A-Za-z0-9+/=]
(i.e. alphanumerics, '+', '/' or '='). =
is a special case, and may only appear at the end of the encoded output, as a single =
or a double ==
. Now, choose your boundary as a 7-bit ASCII string which cannot appear in base64
output. Many choices you see on the net fail this test - the MDN forms docs, for example, use "blob" as a boundary when sending binary data - not good. However, something like "!blob!" will never appear in base64
output.
I did the following using Python 3:
from sys import stderr
def print_err(*args, **kwargs):
print(*args, file=stderr, **kwargs)
So now I'm able to add keyword arguments, for example, to avoid carriage return:
print_err("Error: end of the file reached. The word ", end='')
print_err(word, "was not found")
You could do this with a post build event. Set the files to no action on compile, then in the macro copy the files to the directory you want.
Here's a post build Macro that I think will work by copying all files in a directory called Configuration to the root build folder:
copy $(ProjectDir)Configuration\* $(ProjectDir)$(OutDir)
The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.
Also, I didn't understand when the accepted answer said "it defaults to node server.js
". I think the documentation clarifies the default behavior:
npm-start
Start a package
Synopsis
npm start [-- <args>]
Description
This runs an arbitrary command specified in the package's "
start
" property of its "scripts
" object. If no "start
" property is specified on the "scripts
" object, it will runnode server.js
.
In summary, running npm start
could do one of two things:
npm start {command_name}
: Run an arbitrary command (i.e. if such command is specified in the start
property of package.json's scripts
object)npm start
: Else if no start
property exists (or no command_name
is passed): Run node server.js
, (which may not be appropriate, for example the OP doesn't have server.js
; the OP runs node
app.js
)package.json
in the directory where you run npm start
, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'
Update: Starting with Android SDK Manager version 21, the solution is to edit C:\Users\.android\avd\.avd\config.ini and change the value
hw.ramSize=1024 to
hw.ramSize=1024MB
OR
hw.ramSize=512MB
I'd say
chunks = [data[x:x+100] for x in range(0, len(data), 100)]
If you are using python 2.x instead of 3.x, you can be more memory-efficient by using xrange()
, changing the above code to:
chunks = [data[x:x+100] for x in xrange(0, len(data), 100)]
In my case, I kept ignoring the instructions that very explicitly tell you to use a terminal on Mac OS, because it looked like it was unzipping correctly:
On Linux or Mac OS X you can unzip ngrok from a terminal with the following command. On Windows, just double click ngrok.zip to extract it.
unzip /path/to/ngrok.zip
However, as soon as I tried running the above command in my terminal, it worked perfectly fine!
yes, but you need to open the global search panel. to do so, press the binoculars icon on the top right corner of the IDE.
you can even filter searches by function identifiers, method scopes an etc...
Some numpy functions for how to control the rounding: rint, floor,trunc, ceil. depending how u wish to round the floats, up, down, or to the nearest int.
>>> x = np.array([[1.0,2.3],[1.3,2.9]])
>>> x
array([[ 1. , 2.3],
[ 1.3, 2.9]])
>>> y = np.trunc(x)
>>> y
array([[ 1., 2.],
[ 1., 2.]])
>>> z = np.ceil(x)
>>> z
array([[ 1., 3.],
[ 2., 3.]])
>>> t = np.floor(x)
>>> t
array([[ 1., 2.],
[ 1., 2.]])
>>> a = np.rint(x)
>>> a
array([[ 1., 2.],
[ 1., 3.]])
To make one of this in to int, or one of the other types in numpy, astype (as answered by BrenBern):
a.astype(int)
array([[1, 2],
[1, 3]])
>>> y.astype(int)
array([[1, 2],
[1, 2]])
It is simple actually, like C programming you just need to pass the array indices on the right hand side while declaration. But yeah the syntax will be like [0:3] for 4 elements.
reg a[0:3];
This will create a 1D of array of single bit. Similarly 2D array can be created like this:
reg [0:3][0:2];
Now in C suppose you create a 2D array of int, then it will internally create a 2D array of 32 bits. But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with C, you can't store 5-bits in every element of 2D array in C). So to create a 2D array, in which every individual element can hold 5 bit value, you should write this:
reg [0:4] a [0:3][0:2];
copied from: https://android.stackexchange.com/questions/12962/flush-clear-dns-cache
Addresses are cached for 600 seconds (10 minutes) by default. Failed lookups are cached for 10 seconds. From everything I've seen, there's nothing built in to flush the cache. This is apparently a reported bug http://code.google.com/p/android/issues/detail?id=7904 in Android because of the way it stores DNS cache. Clearing the browser cache doesn't touch the DNS, the "hard reset" clears it.
Also, look at your perfmon counters. They can tell you where a lot of that cpu time is being spent. Here's a link to the most common counters to use:
Adding the following method to your repository should allow you to call $repo->getCourseCount()
from your Controller.
/**

*/
public function getCourseCount()
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb
->select('count(course.id)')
->from('CRMPicco\Component\Course\Model\Course', 'course')
;
$query = $qb->getQuery();
return $query->getSingleScalarResult();
}
In reference to your comment after Ian Henry's answer, I'm not quite 100% sure I understand what you are asking.
If it is about getting double quote marks added into a string, you can concatenate the double quotes into your string, for example:
String theFirst = "Java Programming";
String ROM = "\"" + theFirst + "\"";
Or, if you want to do it with one String variable, it would be:
String ROM = "Java Programming";
ROM = "\"" + ROM + "\"";
Of course, this actually replaces the original ROM, since Java Strings are immutable.
If you are wanting to do something like turn the variable name into a String, you can't do that in Java, AFAIK.

The NuGet documentation provides instructions on how to accomplish this and I just followed them successfully for Visual Studio 2015 & Visual Studio 2017 against VSTS (Azure-hosted TFS). Everything is fully updated as of Nov 2016 Aug 2018.
I recommend you follow NuGet's instructions but just to recap what I did:
packages
folder is not committed to TFS. If it is, get it out of there..sln
file exists in unless otherwise specified (NuGet's instructions aren't completely clear on this)..nuget
folder. You can use Windows Explorer to name it .nuget.
for it to successfully save as .nuget
(it automatically removes the last period) but directly trying to name it .nuget
may not work (you may get an error or it may change the name, depending on your version of Windows).
Or name the directory nuget, and open the parent directory in command line prompt. type. ren nuget .nugetNuGet.config
file and add the following contents and save it:NuGet.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
<add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>
.sln
's folder and create a new text file and name it .tfignore
(if using Windows Explorer, use the same trick as above and name it .tfignore.
).tfignore:
# Ignore the NuGet packages folder in the root of the repository.
# If needed, prefix 'packages' with additional folder names if it's
# not in the same folder as .tfignore.
packages
# include package target files which may be required for msbuild,
# again prefixing the folder name as needed.
!packages/*.targets
.tfignore
file and .nuget
folder to all of my various solutions and committed them and I no longer have the packages
folder trying to sneak into my source control repo!While not mine, I have found this .tfignore
template by sirkirby to be handy. The example in my answer covers the Nuget packages
folder but this template includes some other things as well as provides additional examples that can be useful if you wish to customize this further.

In bash 4.3, the '-v' test for set variables was introduced. At the same time, 'nameref' declaration was added. These two features together with the indirection operator (!) enable a simplified version of the previous example:
get_value()
{
declare -n var_name=$1
if [[ -v var_name ]]
then
echo "${var_name}"
else
echo "variable with name <${!var_name}> is not set"
fi
}
test=123
get_value test
123
test="\$(echo \"something nasty\")"
get_value test
$(echo "something nasty")
unset test
get_value test
variable with name <test> is not set
As this approach eliminates the need for 'eval', it is safer. This code checked under bash 5.0.3(1).

Linux user here: I tried the convert
command-line utility (for PDF to PNG) and I was not happy with the results. I found this to be easier, with a better result:
pdftk file.pdf cat 3 output page3.pdf
GIMP
Resolution
from 100

or 600 pixel/in
GIMP
export as PNG (change file extension to .png)Edit:
Added picture, as requested in the Comments
. Convert command used:
convert -density 300 -trim struct2vec.pdf -quality 100 struct2vec.png
GIMP

I have not used GIMP on the command line (re: my comment, below).
As written, your function accepts only two ranges as arguments.
To allow for a variable number of ranges to be used in the function, you need to declare a ParamArray variant array in your argument list. Then, you can process each of the ranges in the array in turn.
For example,
Function myAdd(Arg1 As Range, ParamArray Args2() As Variant) As Double
Dim elem As Variant
Dim i As Long
For Each elem In Arg1
myAdd = myAdd + elem.Value
Next elem
For i = LBound(Args2) To UBound(Args2)
For Each elem In Args2(i)
myAdd = myAdd + elem.Value
Next elem
Next i
End Function
This function could then be used in the worksheet to add multiple ranges.
For your function, there is the question of which of the ranges (or cells) that can passed to the function are 'Sessions' and which are 'Customers'.
The easiest case to deal with would be if you decided that the first range is Sessions and any subsequent ranges are Customers.
Function calculateIt(Sessions As Range, ParamArray Customers() As Variant) As Double
'This function accepts a single Sessions range and one or more Customers
'ranges
Dim i As Long
Dim sessElem As Variant
Dim custElem As Variant
For Each sessElem In Sessions
'do something with sessElem.Value, the value of each
'cell in the single range Sessions
Debug.Print "sessElem: " & sessElem.Value
Next sessElem
'loop through each of the one or more ranges in Customers()
For i = LBound(Customers) To UBound(Customers)
'loop through the cells in the range Customers(i)
For Each custElem In Customers(i)
'do something with custElem.Value, the value of
'each cell in the range Customers(i)
Debug.Print "custElem: " & custElem.Value
Next custElem
Next i
End Function
If you want to include any number of Sessions ranges and any number of Customers range, then you will have to include an argument that will tell the function so that it can separate the Sessions ranges from the Customers range.
This argument could be set up as the first, numeric, argument to the function that would identify how many of the following arguments are Sessions ranges, with the remaining arguments implicitly being Customers ranges. The function's signature would then be:
Function calculateIt(numOfSessionRanges, ParamAray Args() As Variant)
Or it could be a "guard" argument that separates the Sessions ranges from the Customers ranges. Then, your code would have to test each argument to see if it was the guard. The function would look like:
Function calculateIt(ParamArray Args() As Variant)
Perhaps with a call something like:
calculateIt(sessRange1,sessRange2,...,"|",custRange1,custRange2,...)
The program logic might then be along the lines of:
Function calculateIt(ParamArray Args() As Variant) As Double
...
'loop through Args
IsSessionArg = True
For i = lbound(Args) to UBound(Args)
'only need to check for the type of the argument
If TypeName(Args(i)) = "String" Then
IsSessionArg = False
ElseIf IsSessionArg Then
'process Args(i) as Session range
Else
'process Args(i) as Customer range
End if
Next i
calculateIt = <somevalue>
End Function
The simplest way to connect is through an OdbcConnection using code like this
using System.Data.Odbc;
using(OdbcConnection myConnection = new OdbcConnection())
{
myConnection.ConnectionString = myConnectionString;
myConnection.Open();
//execute queries, etc
}
where myConnectionString is something like this
myConnectionString = @"Driver={Microsoft Access Driver (*.mdb)};" +
"Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;
In alternative you could create a DSN and then use that DSN in your connection string
now your connectionString could be written in this way
myConnectionString = "DSN=myDSN;"
I have had this problem several times and it can be usually resolved with a clean and rebuild as answered by many before me. But this time this would not fix it.
I use my cordova app to build 2 seperate apps that share majority of the same codebase and it drives off the config.xml. I could not build in end up because i had a space in my id.
com.company AppName
instead of:
com.company.AppName
If anyone is in there config as regular as me. This could be your problem, I also have 3 versions of each app. Live / Demo / Test - These all have different ids.
com.company.AppName.Test
Easy mistake to make, but even easier to overlook. Spent loads of time rebuilding, checking plugins, versioning etc. Where I should have checked my config. First Stop Next Time!
Radio buttons are,
<input type="radio" id="radio_1" class="radioButtons" name="radioButton" value="1">
<input type="radio" id="radio_2" class="radioButtons" name="radioButton" value="2">
to check on click,
$('.radioButtons').click(function(){
if($("#radio_1")[0].checked){
//logic here
}
});
Methods and variables that are not declared as static are known as instance methods and instance variables. To refer to instance methods and variables, you must instantiate the class first means you should create an object of that class first.For static you don't need to instantiate the class u can access the methods and variables with the class name using period sign which is in (.)
for example:
Person.staticMethod(); //accessing static method.
for non-static method you must instantiate the class.
Person person1 = new Person(); //instantiating
person1.nonStaticMethod(); //accessing non-static method.
I use this super easy solution with clearfix
, which doesn't have any side effects.
Here is an example on AngularJS:
<div ng-repeat-start="item in list">
<div class="col-lg-4 col-md-6 col-sm-12 col-xs-12"></div>
</div>
<div ng-repeat-end>
<div ng-if="$index % 3 == 2" class="clearfix visible-lg"></div>
<div ng-if="$index % 2 == 1" class="clearfix visible-md"></div>
</div>
And one more example on PHP:
<?php foreach ($list as $i => $item): ?>
<div class="col-lg-4 col-md-6 col-sm-12 col-xs-12"></div>
<div class="clearfix visible-md"></div>
<?php if ($i % 2 === 1): ?>
<div class="clearfix visible-lg"></div>
<?php endif; ?>
<?php endforeach; ?>
You kill a session like this:
Session.Abandon()
If, however, you just want to empty the session, use:
Session.Clear()
You can simply use BeginInvokeOnMainThread(). It invokes an Action on the device main (UI) thread.
Device.BeginInvokeOnMainThread(() => { displayToast("text to display"); });
It is simple and works perfectly for me!
EDIT : Works if you're using C# Xamarin
Clang's document on Objective-C Automatic Reference Counting (ARC) explains the ownership qualifiers and modifiers clearly:
There are four ownership qualifiers:
- __autoreleasing
- __strong
- __*unsafe_unretained*
- __weak
A type is nontrivially ownership-qualified if it is qualified with __autoreleasing, __strong, or __weak.
Then there are six ownership modifiers for declared property:
- assign implies __*unsafe_unretained* ownership.
- copy implies __strong ownership, as well as the usual behavior of copy semantics on the setter.
- retain implies __strong ownership.
- strong implies __strong ownership.
- *unsafe_unretained* implies __*unsafe_unretained* ownership.
- weak implies __weak ownership.
With the exception of weak, these modifiers are available in non-ARC modes.
Semantics wise, the ownership qualifiers have different meaning in the five managed operations: Reading, Assignment, Initialization, Destruction and Moving, in which most of times we only care about the difference in Assignment operation.
Assignment occurs when evaluating an assignment operator. The semantics vary based on the qualification:
- For __strong objects, the new pointee is first retained; second, the lvalue is loaded with primitive semantics; third, the new pointee is stored into the lvalue with primitive semantics; and finally, the old pointee is released. This is not performed atomically; external synchronization must be used to make this safe in the face of concurrent loads and stores.
- For __weak objects, the lvalue is updated to point to the new pointee, unless the new pointee is an object currently undergoing deallocation, in which case the lvalue is updated to a null pointer. This must execute atomically with respect to other assignments to the object, to reads from the object, and to the final release of the new pointee.
- For __*unsafe_unretained* objects, the new pointee is stored into the lvalue using primitive semantics.
- For __autoreleasing objects, the new pointee is retained, autoreleased, and stored into the lvalue using primitive semantics.
The other difference in Reading, Init, Destruction and Moving, please refer to Section 4.2 Semantics in the document.
How you loop through an array, depends on the presence of new line characters. With new line characters separating the array elements, the array can be referred to as "$array"
, otherwise it should be referred to as "${array[@]}"
. The following script will make it clear:
#!/bin/bash
mkdir temp
mkdir temp/aaa
mkdir temp/bbb
mkdir temp/ccc
array=$(ls temp)
array1=(aaa bbb ccc)
array2=$(echo -e "aaa\nbbb\nccc")
echo '$array'
echo "$array"
echo
for dirname in "$array"; do
echo "$dirname"
done
echo
for dirname in "${array[@]}"; do
echo "$dirname"
done
echo
echo '$array1'
echo "$array1"
echo
for dirname in "$array1"; do
echo "$dirname"
done
echo
for dirname in "${array1[@]}"; do
echo "$dirname"
done
echo
echo '$array2'
echo "$array2"
echo
for dirname in "$array2"; do
echo "$dirname"
done
echo
for dirname in "${array2[@]}"; do
echo "$dirname"
done
rmdir temp/aaa
rmdir temp/bbb
rmdir temp/ccc
rmdir temp

If you don't reference the imageBytes to carry bytes in the stream, the method won't return anything. Make sure you reference imageBytes = m.ToArray();
public static byte[] SerializeImage() {
MemoryStream m;
string PicPath = pathToImage";
byte[] imageBytes;
using (Image image = Image.FromFile(PicPath)) {
using ( m = new MemoryStream()) {
image.Save(m, image.RawFormat);
imageBytes = new byte[m.Length];
//Very Important
imageBytes = m.ToArray();
}//end using
}//end using
return imageBytes;
}//SerializeImage
A more simplified version of the above and presuming you're not using custom indexes...
$len = count($array);
foreach ($array as $index => $item) {
if ($index == 0) {
// first
} else if ($index == $len - 1) {
// last
}
}
Version 2 - Because I have come to loathe using the else unless necessary.
$len = count($array);
foreach ($array as $index => $item) {
if ($index == 0) {
// first
// do something
continue;
}
if ($index == $len - 1) {
// last
// do something
continue;
}
}
Besides convenience in insertions and deletions, the memory representation of linked list is different than the arrays. There is no restriction on the number of elements in a linked list, while in the arrays, you have to specify the total number of elements. Check this article.
Function FileExists(fullFileName As String) As Boolean
FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End Function
Works very well, almost, at my site. If I call it with "" the empty string, Dir returns "connection.odc"!! Would be great if you guys could share your result.
Anyway, I do like this:
Function FileExists(fullFileName As String) As Boolean
If fullFileName = "" Then
FileExists = False
Else
FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End If
End Function
HTML5 introduced a file upload api that allows you to monitor the progress of file uploads but for older browsers there's plupload a framework that specifically made to monitor file uploads and give information about them. plus it has plenty of callbacks so it can work across all browsers

If its a 32 bit COM/Active X, use version 32 bit of cscript.exe/wscript.exe located in C:\Windows\SysWOW64\
This will work:
if 'A' in df:
But for clarity, I'd probably write it as:
if 'A' in df.columns:
To get the correct orientation on app start you have to check it in viewDidLayoutSubviews()
. Other methods described here won't work.
Here's an example how to do it:
var mFirstStart = true
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if (mFirstStart) {
mFirstStart = false
detectOrientation()
}
}
func detectOrientation() {
if UIDevice.current.orientation.isLandscape {
print("Landscape")
// do your stuff here for landscape
} else {
print("Portrait")
// do your stuff here for portrait
}
}
override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
detectOrientation()
}
This will work always, on app first start, and if rotating while the app is running.
I had the same error, but in Ubuntu 14.04 inside Windows 10 (Bash on Ubuntu on Windows). All I did to overcome the error was to update the Creators update, which then allowed me to install 16.04 version of Ubuntu bash and then after installing newest version of node (by this steps) I installed also the newest version of npm and then the nodemon started to work properly.
Probably the shortest way to do this is:
if(EmpName == null) { /* DO SOMETHING */ };
Here is proof:

return false;_x000D_
}_x000D_
_x000D_
var log = (t,a) => console.log(`${t} -> ${check(a)}`);_x000D_

And here are more details about ==
(source here)
BONUS: reason why ===
is more clear than ==
(look on agc answer)
Consider using a subquery:
from p in context.ParentTable
let cCount =
(
from c in context.ChildTable
where p.ParentId == c.ChildParentId
select c
).Count()
select new { ParentId = p.Key, Count = cCount } ;
If the query types are connected by an association, this simplifies to:
from p in context.ParentTable
let cCount = p.Children.Count()
select new { ParentId = p.Key, Count = cCount } ;

There are several examples on DZone Snippets if you want to roll your own that works with a Collection. For example:
public static String join(AbstractCollection<String> s, String delimiter) {
if (s == null || s.isEmpty()) return "";
Iterator<String> iter = s.iterator();
StringBuilder builder = new StringBuilder(iter.next());
while( iter.hasNext() )
{
builder.append(delimiter).append(iter.next());
}
return builder.toString();
}
EDIT: I would appreciate it if you do not downvote this answer further. This answer is wrong, but I would rather retain it as a historical note. While it is arguable whether the pytz interface is error-prone, it can do things that dateutil.tz cannot do, especially regarding daylight-saving in the past or in the future. I have honestly recorded my experience in an article "Time zones in Python".
If you are on a Unix-like platform, I would suggest you avoid pytz and look just at /usr/share/zoneinfo. dateutil.tz can utilize the information there.
The following piece of code shows the problem pytz can give. I was shocked when I first found it out. (Interestingly enough, the pytz installed by yum on CentOS 7 does not exhibit this problem.)
import pytz
import dateutil.tz
from datetime import datetime
print((datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('Asia/Shanghai'))
- datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('UTC')))
.total_seconds())
print((datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.gettz('Asia/Shanghai'))
- datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.tzutc()))
.total_seconds())
-29160.0
-28800.0
I.e. the timezone created by pytz is for the true local time, instead of the standard local time people observe. Shanghai conforms to +0800, not +0806 as suggested by pytz:
pytz.timezone('Asia/Shanghai')
<DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD>
EDIT: Thanks to Mark Ransom's comment and downvote, now I know I am using pytz the wrong way. In summary, you are not supposed to pass the result of pytz.timezone(…)
to datetime
, but should pass the datetime
to its localize
method.
Despite his argument (and my bad for not reading the pytz documentation more carefully), I am going to keep this answer. I was answering the question in one way (how to enumerate the supported timezones, though not with pytz), because I believed pytz did not provide a correct solution. Though my belief was wrong, this answer is still providing some information, IMHO, which is potentially useful to people interested in this question. Pytz's correct way of doing things is counter-intuitive. Heck, if the tzinfo created by pytz should not be directly used by datetime
, it should be a different type. The pytz interface is simply badly designed. The link provided by Mark shows that many people, not just me, have been misled by the pytz interface.
I was looking for a way to prevent all body scrolling when there's a popup with a scrollable area (a "shopping cart" popdown that has a scrollable view of your cart).
I wrote a far more elegant solution using minimal javascript to just toggle the class "noscroll" on your body when you have a popup or div that you'd like to scroll (and not "overscroll" the whole page body).
while desktop browsers observe overflow:hidden -- iOS seems to ignore that unless you set the position to fixed... which causes the whole page to be a strange width, so you have to set the position and width manually as well. use this css:
.noscroll {
overflow: hidden;
position: fixed;
top: 0;
left: 0;
width: 100%;
}
and this jquery:
/* fade in/out cart popup, add/remove .noscroll from body */
$('a.cart').click(function() {
$('nav > ul.cart').fadeToggle(100, 'linear');
if ($('nav > ul.cart').is(":visible")) {
$('body').toggleClass('noscroll');
} else {
$('body').removeClass('noscroll');
}
});
/* close all popup menus when you click the page... */
$('body').click(function () {
$('nav > ul').fadeOut(100, 'linear');
$('body').removeClass('noscroll');
});
/* ... but prevent clicks in the popup from closing the popup */
$('nav > ul').click(function(event){
event.stopPropagation();
});

Nobody answered with regular for

$keys = array_keys($array);
for($i=0; $i < count($keys); ++$i) {
echo $keys[$i] . ' ' . $array[$keys[$i]] . "\n";
}

Why not use the s3path
package which makes it as convenient as working with pathlib
? If you must however use boto3
:
boto3.resource
This builds upon the answer by itz-azhar to apply an optional limit
. It is obviously substantially simpler to use than the boto3.client
version.
import logging
from typing import List, Optional
import boto3
from boto3_type_annotations.s3 import ObjectSummary # pip install boto3_type_annotations
log = logging.getLogger(__name__)
_S3_RESOURCE = boto3.resource("s3")
def s3_list(bucket_name: str, prefix: str, *, limit: Optional[int] = None) -> List[ObjectSummary]:
"""Return a list of S3 object summaries."""
# Ref: https://stackoverflow.com/a/57718002/
return list(_S3_RESOURCE.Bucket(bucket_name).objects.limit(count=limit).filter(Prefix=prefix))
if __name__ == "__main__":
s3_list("noaa-gefs-pds", "gefs.20190828/12/pgrb2a", limit=10_000)
boto3.client
This uses list_objects_v2
and builds upon the answer by CpILL to allow retrieving more than 1000 objects.
import logging
from typing import cast, List
import boto3
log = logging.getLogger(__name__)
_S3_CLIENT = boto3.client("s3")
def s3_list(bucket_name: str, prefix: str, *, limit: int = cast(int, float("inf"))) -> List[dict]:
"""Return a list of S3 object summaries."""
# Ref: https://stackoverflow.com/a/57718002/
contents: List[dict] = []
continuation_token = None
if limit <= 0:
return contents
while True:
max_keys = min(1000, limit - len(contents))
request_kwargs = {"Bucket": bucket_name, "Prefix": prefix, "MaxKeys": max_keys}
if continuation_token:
log.info( # type: ignore
"Listing %s objects in s3://%s/%s using continuation token ending with %s with %s objects listed thus far.",
max_keys, bucket_name, prefix, continuation_token[-6:], len(contents)) # pylint: disable=unsubscriptable-object
response = _S3_CLIENT.list_objects_v2(**request_kwargs, ContinuationToken=continuation_token)
else:
log.info("Listing %s objects in s3://%s/%s with %s objects listed thus far.", max_keys, bucket_name, prefix, len(contents))
response = _S3_CLIENT.list_objects_v2(**request_kwargs)
assert response["ResponseMetadata"]["HTTPStatusCode"] == 200
contents.extend(response["Contents"])
is_truncated = response["IsTruncated"]
if (not is_truncated) or (len(contents) >= limit):
break
continuation_token = response["NextContinuationToken"]
assert len(contents) <= limit
log.info("Returning %s objects from s3://%s/%s.", len(contents), bucket_name, prefix)
return contents
if __name__ == "__main__":
s3_list("noaa-gefs-pds", "gefs.20190828/12/pgrb2a", limit=10_000)
Or use awk
instead:
awk '/null/ { counter++; printf("%s%s%i\n",$0, " - Line number: ", NR)} END {print "Total null count: " counter}' file
For anyone looking to style child elements of a :host
here is an example of how to use ::ng-deep
:host::ng-deep <child element>
e.g :host::ng-deep span { color: red; }
As others said /deep/
is deprecated
The other answers that suggest keeping a reference to the activity in onAttach are just suggesting a bandaid to the real problem. When getActivity returns null it means that the Fragment is not attached to the Activity. Most commonly this happens when the Activity has gone away due to rotation or the Activity being finished but the Fragment still has some kind of callback listener registered. When the listener gets called if you need to do something with the Activity but the Activity is gone there isn't much you can do. In your code you should just check getActivity() != null
and if it's not there then don't do anything. If you keep a reference to the Activity that is gone you are preventing the Activity from being garbage collected. Any UI things you might try to do won't be seen by the user. I can imagine some situations where in the callback listener you want to have a Context for something non-UI related, in those cases it probably makes more sense to get the Application context. Note that the only reason that the onAttach
trick isn't a big memory leak is because normally after the callback listener executes it won't be needed anymore and can be garbage collected along with the Fragment, all its View's and the Activity context. If you setRetainInstance(true)
there is a bigger chance of a memory leak because the Activity field will also be retained but after rotation that could be the previous Activity not the current one.
Some times you may make silly mistakes like writing insert query on the same .sql file (in the same workspace/tab) so once you execute the insert query where your create query was written just above and already executed, it will again start executing along with the insert query.
This is the reason why we are getting the object name (table name) exists already, since it's getting executed for the second time.
So go to a separate tab to write the insert or drop or whatever queries you are about to execute.
Or else use comment lines preceding all queries in the same workspace like
CREATE -- …
-- Insert query
INSERT INTO -- …
I had the same issue to connect to local system.
I checked in the services list (Run->Services.msc->Enter) wampmysqld64 was stopped.
Restarted it. and was able to login.
You have to override the bootstrap default by being a bit more specific. Try this for a black background:
html body {
background-color: rgba(0,0,0,1.00);
}
For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
This works for me as a "simplified" version of previous posted answers.
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] init];
backButton.title = @"Go Back";
self.navigationItem.backBarButtonItem = backButton;
Remember to put the code inside the parent view controller (e.g. the view that has your table view or UITableViewController), not the child or detail view (e.g. UIViewController).
You can easily localize the back button string like this:
backButton.title = NSLocalizedString(@"Back Title", nil);
for (Int32 i = 1; i < dt_pattern.Rows.Count - 1; i++){
double yATmax = ToDouble(dt_pattern.Rows[i]["Ampl"].ToString()) + AT;
}
if you want to get around the + 1 issue
For those who created rating bar programmatically and want set small rating bar instead of default big rating bar
private LinearLayout generateRatingView(float value){ LinearLayout linearLayoutRating=new LinearLayout(getContext()); linearLayoutRating.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT)); linearLayoutRating.setGravity(Gravity.CENTER); RatingBar ratingBar = new RatingBar(getContext(),null, android.R.attr.ratingBarStyleSmall); ratingBar.setEnabled(false); ratingBar.setStepSize(Float.parseFloat("0.5"));//for enabling half star ratingBar.setNumStars(5); ratingBar.setRating(value); linearLayoutRating.addView(ratingBar); return linearLayoutRating; }
The feedback you get on the interactive interpreter uses repr
too. When you type in an expression (let it be expr
), the interpreter basically does result = expr; if result is not None: print repr(result)
. So the second line in your example is formatting the string foo
into the representation you want ('foo'
). And then the interpreter creates the repr
esentation of that, leaving you with double quotes.
Why when I combine %r with double-quote and single quote escapes and print them out, it prints it the way I'd write it in my .py file but not the way I'd like to see it?
I'm not sure what you're asking here. The text single ' and double " quotes
, when run through repr
, includes escapes for one kind of quote. Of course it does, otherwise it wouldn't be a valid string literal by Python rules. That's precisely what you asked for by calling repr
.
Also note that the eval(repr(x)) == x
analogy isn't meant literal. It's an approximation and holds true for most (all?) built-in types, but the main thing is that you get a fairly good idea of the type and logical "value" from looking the the repr
output.
Maven kept your files on cache, and don't retry to download them. You can simply manually 'help' him by deleting the .m2
directory, and then our friend will download everything over the old dependencies.
Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.
Pandas is a library for handling data in Python, preferred by many Data Scientists.
Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.
In your case:
import pandas
def create_dictionary(filename):
my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
# Here you can delete the dataframe columns you don't want!
del my_data['B']
del my_data['D']
# ...
# Now you transform the DataFrame to a list of dictionaries
list_of_dicts = [item for item in my_data.T.to_dict().values()]
return list_of_dicts
# Usage:
x = create_dictionary("myfile.csv")
You'll need to reload the table on the UI
thread via:
//swift 2.3
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.tableView.reloadData()
})
//swift 5
DispatchQueue.main.async{
self.tableView.reloadData()
}
Follow up:
An easier alternative to the connection.start()
approach is to instead use NSURLConnection.sendAsynchronousRequest(...)
//NSOperationQueue.mainQueue() is the main thread
NSURLConnection.sendAsynchronousRequest(NSURLRequest(URL: url), queue: NSOperationQueue.mainQueue()) { (response, data, error) -> Void in
//check error
var jsonError: NSError?
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: &jsonError)
//check jsonError
self.collectionView?.reloadData()
}
This doesn't allow you the flexibility of tracking the bytes though, for example you might want to calculate the progress of the download via bytesDownloaded/bytesNeeded
Add the class constraint as the first constraint to your generic type.
static T FindThing<T>(IList collection, int id) where T : class, IThing, new()
Much simpler and straight-forward one; with option to deep flatten;
const flatReduce = (arr, deep) => {
return arr.reduce((acc, cur) => {
return acc.concat(Array.isArray(cur) && deep ? flatReduce(cur, deep) : cur);
}, []);
};
console.log(flatReduce([1, 2, [3], [4, [5]]], false)); // => 1,2,3,4,[5]
console.log(flatReduce([1, 2, [3], [4, [5, [6, 7, 8]]]], true)); // => 1,2,3,4,5,6,7,8
This will search text in all the td's inside each tr and show/hide tr's based on search text
$.each($(".table tbody").find("tr"), function () {
if ($(this).text().toLowerCase().replace(/\s+/g, '').indexOf(searchText.replace(/\s+/g, '').toLowerCase()) == -1)
$(this).hide();
else
$(this).show();
});
Wikipedia explains it better then I could

Here's an answer regarding the XML configuration, note that if you don't give the file appender a ConversionPattern
it will create 0 byte file and not write anything:

Close android studio and open it again. Then try compiling the same code. I was getting the same error and it worked for me. Hope it helps.
You can pass the authorised keys in to your container using a shared folder and set permissions using a docker file like this:
FROM ubuntu:16.04
RUN apt-get install -y openssh-server
RUN mkdir /var/run/sshd
EXPOSE 22
RUN cp /root/auth/id_rsa.pub /root/.ssh/authorized_keys
RUN rm -f /root/auth
RUN chmod 700 /root/.ssh
RUN chmod 400 /root/.ssh/authorized_keys
RUN chown root. /root/.ssh/authorized_keys
CMD /usr/sbin/sshd -D
And your docker run contains something like the following to share an auth directory on the host (holding the authorised_keys) with the container then open up the ssh port which will be accessable through port 7001 on the host.
-d -v /home/thatsme/dockerfiles/auth:/root/auth -–publish=127.0.0.1:7001:22
You may want to look at https://github.com/jpetazzo/nsenter which appears to be another way to open a shell on a container and execute commands within a container.
You can use inline styling to limit the height:
<img src="" class="img-responsive" alt="" style="max-height: 400px;">
I was getting this error for lots of entities when I was migrating down from an EF7 model to an EF6 version. I didn't want to have to go through each entity one at a time, so I used:
builder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
builder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
This property exists : TreeView.SelectedItem
But it is readonly, so you cannot assign it through a binding, only retrieve it
For the benefit of anyone who might believe e.g. that doing aset.add()
in a loop would have performance competitive with doing aset.update()
, here's an example of how you can test your beliefs quickly before going public:
>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 294 usec per loop
>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 950 usec per loop
>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 458 usec per loop
>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 598 usec per loop
>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 1.89 msec per loop
>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 891 usec per loop
Looks like the cost per item of the loop approach is over THREE times that of the update
approach.
Using |= set()
costs about 1.5x what update
does but half of what adding each individual item in a loop does.
I have a similar problem and as I'm newbie, here are some facts for somebody to comment:
I'm sending form data to Google sheet this way (scriptURL is https://script.google.com/macros/s/AKfy..., showSuccess() is showing a simple image):
fetch(scriptURL, {method: 'POST', body: new FormData(form)})
.then(response => showSuccess())
.catch(error => alert('Error! ' + error.message))
Executed in Edge my HTML doesn't show error and Network tab reports this 3 requests: Executed in Chrome my HTML (index.htm) shows Failed to fetch error and Network tab reports this 2 requests: The value in the second column is blocked:other and there is also an error in Console tab:
GET https://script.googleusercontent.com/macros/echo?user_content_key=D-ABF... net::ERR_BLOCKED_BY_CLIENT
In order to suspend installed Chrome extensions, I executed my code in an Incognito window and there is no error message and Network tab reports this 2 requests:
My guess is that something (extension?) prevents Chrome to read the request's answer (the GET request is blocked).
If all of the above doesn't work for you:
window.location.reload();
This for some reason refreshed my iframe instead of the whole script. Maybe because it is placed in the frame itself, while all those getElemntById solutions work when you try to refresh a frame from another frame?
Or I don't understand this fully and talk gibberish, anyways this worked for me like a charm :)

Here is solution implemented with ES6
const toggleClass = (el, className) => el.classList.toggle(className);
usage example
toggleClass(document.querySelector('div.active'), 'active'); // The div container will not have the 'active' class anymore
Try underscore-cli:
cat myfile.json | underscore print --color
It's a pretty nifty tool that can elegantly do a lot of manipulation of structured data, execute js snippets, fill templates, etc. It's ridiculously well documented, polished, and ready for serious use. And I wrote it. :)
This is partly based on this earlier answer above by @A Boschman. In that solution, I found that the input size of the image greatly affected the ability of makeImageSpan()
to properly center-align the image. Additionally, I found that the solution affected text spacing by creating unnecessary line spacing.
I found BaseImageSpan (from Facebook's Fresco library) to do the job particularly well:
/**
* Create an ImageSpan for the given icon drawable. This also sets the image size. Works best
* with a square icon because of the sizing
*
* @param context The Android Context.
* @param drawableResId A drawable resource Id.
* @param size The desired size (i.e. width and height) of the image icon in pixels.
* Use the lineHeight of the TextView to make the image inline with the
* surrounding text.
* @return An ImageSpan, aligned with the bottom of the text.
*/
private static BetterImageSpan makeImageSpan(Context context, int drawableResId, int size) {
final Drawable drawable = context.getResources().getDrawable(drawableResId);
drawable.mutate();
drawable.setBounds(0, 0, size, size);
return new BetterImageSpan(drawable, BetterImageSpan.ALIGN_CENTER);
}
Then supply your betterImageSpan instance to spannable.setSpan()
as usual

2018 update:
For AdMob users, this causes AdMob version 12.0.0 (currently last version). It wrongly requests READ_PHONE_STATE permission, so even if your app doesn't require READ_PHONE_STATE permission in manifest, you won't be able to update your app in the Google Play Console (it will tell you to create a privacy policy page for your app, because your app requires this permission).
See this: https://developers.google.com/android/guides/releases#march_20_2018_-_version_1200
Also, they wrote they will publish an update to 12.0.1 fixing this soon.
Maybe worth mentioning that when I had this problem I followed bia.migueis's advice - move everything out of the plugins folder - and the workspace would open again, minus a lot of my configuration. But then after that, I copied/overwrote all the original files back into the plugins folder and opened the workspace again: it still worked and the settings I'd had before seemed to be intact.
If you want to DUMP your inserts into an .sql file:
cd
to the location which you want to .sql
file to be locatedpg_dump --column-inserts --data-only --table=<table> <database> > my_dump.sql
Note the > my_dump.sql
command. This will put everything into a sql file named my_dump
function _settimezone($time,$defaultzone,$newzone)
{
$date = new DateTime($time, new DateTimeZone($defaultzone));
$date->setTimezone(new DateTimeZone($newzone));
$result=$date->format('Y-m-d H:i:s');
return $result;
}
$defaultzone="UTC";
$newzone="America/New_York";
$time="2011-01-01 15:00:00";
$newtime=_settimezone($time,$defaultzone,$newzone);
Be aware of that if you use nested transactions, a ROLLBACK operation rolls back all the nested transactions including the outer-most one.
This might, with usage in combination with TRY/CATCH, result in the error you described. See more here.
Start Task Manager, click on the Processes tab, right-click on wscript.exe and select End Process, and confirm in the dialog that follows. This will terminate the wscript.exe that is executing your script.
I would be very concerned about putting the load of sending e-mails on my database server (small though it may be). I might suggest one of these alternatives:
Try this:
string callbackurl = Request.Url.Host != "localhost"
? Request.Url.Host : Request.Url.Authority;
This will work for local as well as production environment. Because the local uses url with port no that is possible using Url.Host.
For latest laravel version also check your version because I was also facing this error but after update latest php version, I got rid from this error.
Maybe some AJAX page content injection could be used as an alternative, though I still can't get around why your teacher would refuse to rid the website of frames.
Additionally, is there any specific reason you personally want to us HTML5?
But if not, I believe <iframe>
s are still around.
A cute piece of numerical weirdness may be observed if one converts 9999999.4999999999 to a float
and back to a double
. The result is reported as 10000000, even though that value is obviously closer to 9999999, and even though 9999999.499999999 correctly rounds to 9999999.
For SQL 2008 and newer, a more concise method, coding-wise, to detect index existence is by using the INDEXPROPERTY
built-in function:
INDEXPROPERTY ( object_ID , index_or_statistics_name , property )
The simplest usage is with the IndexID
property:
If IndexProperty(Object_Id('MyTable'), 'MyIndex', 'IndexID') Is Null
If the index exists, the above will return its ID; if it doesn't, it will return NULL
.
Try something like this (use this.url to get the url):
$.ajax({
url: 'http://www.example.org',
data: {'a':1,'b':2,'c':3},
dataType: 'xml',
complete : function(){
alert(this.url)
},
success: function(xml){
}
});

Just using special Closure
// declare and implement:
def eachWithBreak = { list, Closure c ->
boolean bBreak = false
list.each() { it ->
if (bBreak) return
bBreak = c(it)
}
}
def list = [1,2,3,4,5,6]
eachWithBreak list, { it ->
if (it > 3) return true // break 'eachWithBreak'
println it
return false // next it
}
Nowadays you can also use lazy_eval
function from lazyeval
package.

Take an extension from the file and see if it is in the set of extensions:
>>> import os
>>> extensions = set(['.mp3','.avi'])
>>> file_name = 'test.mp3'
>>> extension = os.path.splitext(file_name)[1]
>>> extension in extensions
True
Using a set because time complexity for lookups in sets is O(1) (docs).
Actually openssl
command is a better tool than curl
for checking and debugging SSL. Here is an example with openssl
:
openssl s_client -showcerts -connect stackoverflow.com:443 < /dev/null
and < /dev/null
is for adding EOL to the STDIN
otherwise it hangs on the Terminal.
But if you liked, you can wrap some useful openssl
commands with curl
(as I did with curly) and make it more human readable like so:
# check if SSL is valid
>>> curly --ssl valid -d stackoverflow.com
Verify return code: 0 (ok)
issuer=C = US
O = Let's Encrypt
CN = R3
subject=CN = *.stackexchange.com

# check how many days it will be valid

Your code makes no sense, maybe because it's out of context.
If you mean code like this:
$('a').click(function () {
callFunction();
return false;
});
The return false will return false to the click-event. That tells the browser to stop following events, like follow a link. It has nothing to do with the previous function call. Javascript runs from top to bottom more or less, so a line cannot affect a previous line.
Gimp can be used to convert SVGs with primitives (e.g. rects, circles, etc.) into a single path which can be used within HTML5.
.svg
file with any tool of choice e.g. Illustrator. Don't worry if the SVG output is messy for now, Gimp will clean it upCheck both the Import Paths and Merge imported paths options
<path d="copy this text here" />
It is useful to know that enums
are just like the other classes with Constant
fields and a private constructor
.
For example,
public enum Weekday
{
MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
}
The compiler compiles it as follows;
class Weekday extends Enum
{
public static final Weekday MONDAY = new Weekday( "MONDAY", 0 );
public static final Weekday TUESDAY = new Weekday( "TUESDAY ", 1 );
public static final Weekday WEDNESDAY= new Weekday( "WEDNESDAY", 2 );
public static final Weekday THURSDAY= new Weekday( "THURSDAY", 3 );
public static final Weekday FRIDAY= new Weekday( "FRIDAY", 4 );
public static final Weekday SATURDAY= new Weekday( "SATURDAY", 5 );
public static final Weekday SUNDAY= new Weekday( "SUNDAY", 6 );
private Weekday( String s, int i )
{
super( s, i );
}
// other methods...
}
function arrUnique(arr) {
var cleaned = [];
arr.forEach(function(itm) {
var unique = true;
cleaned.forEach(function(itm2) {
if (_.isEqual(itm, itm2)) unique = false;
});
if (unique) cleaned.push(itm);
});
return cleaned;
}
var standardsList = arrUnique(standardsList);
This will return
var standardsList = [
{"Grade": "Math K", "Domain": "Counting & Cardinality"},
{"Grade": "Math K", "Domain": "Geometry"},
{"Grade": "Math 1", "Domain": "Counting & Cardinality"},
{"Grade": "Math 1", "Domain": "Orders of Operation"},
{"Grade": "Math 2", "Domain": "Geometry"}
];
Which is exactly what you asked for ?
SOLUTION for: mongoengine + marshmallow
If you use mongoengine
and marshamallow
then this solution might be applicable for you.
Basically, I imported String
field from marshmallow, and I overwritten default Schema id
to be String
encoded.
from marshmallow import Schema
from marshmallow.fields import String
class FrontendUserSchema(Schema):
id = String()
class Meta:
fields = ("id", "email")
What you're doing is valid for the current session (limited to the terminal that you're working in). You need to persist those changes. Consider adding commands in steps 1-3 above to your ${HOME}/.bashrc
.
All variables are cached so the loop and keyup event doesn't have to create a jQuery object everytime it runs.
var $input = $('input:text'),
$register = $('#register');
$register.attr('disabled', true);
$input.keyup(function() {
var trigger = false;
$input.each(function() {
if (!$(this).val()) {
trigger = true;
}
});
trigger ? $register.attr('disabled', true) : $register.removeAttr('disabled');
});

Lots of hate for the Convert class here... Just to balance a little bit, there is one advantage for Convert - if you are handed an object,
Convert.ToDouble(o);
can just return the value easily if o is already a Double (or an int or anything readily castable).
Using Double.Parse or Double.TryParse is great if you already have it in a string, but
Double.Parse(o.ToString());
has to go make the string to be parsed first and depending on your input that could be more expensive.
Only static functions are called with class name.
classname::Staicfunction();
Non static functions have to be called using objects.
classname obj;
obj.Somefunction();
This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.
Here are 4 items, with their index
0 1 2 3
K C A E
You want to move K to between A and E -- you might think position 3. You have be careful about your indexing here, because after the remove, all the indexes get updated.
So you remove item 0 first, leaving
0 1 2
C A E
Then you insert at 3
0 1 2 3
C A E K
To get the correct result, you should have used index 2. To make things consistent, you will need to send to (indexToMoveTo-1) if indexToMoveTo > indexToMove
, e.g.
bool moveUp = (listInstance.IndexOf(itemToMoveTo) > indexToMove);
listInstance.Remove(itemToMove);
listInstance.Insert(indexToMoveTo, moveUp ? (itemToMoveTo - 1) : itemToMoveTo);
This may be related to your problem. Note my code is untested!
EDIT: Alternatively, you could Sort
with a custom comparer (IComparer
) if that's applicable to your situation.
For shortened Hex code
int red = colorString.charAt(1) == '0' ? 0 : 255;
int blue = colorString.charAt(2) == '0' ? 0 : 255;
int green = colorString.charAt(3) == '0' ? 0 : 255;
Color.rgb(red, green,blue);
There is a very elegant solution to this problem, just configure your site via web.config:
<system.webServer>
<httpErrors errorMode="DetailedLocalOnly" existingResponse="PassThrough"/>
</system.webServer>
I tried to avoid too much custom CSS and after reading some other examples I merged the ideas there and got this solution:
<div class="form-group has-feedback has-clear">
<input type="text" class="form-control" ng-model="ctrl.searchService.searchTerm" ng-change="ctrl.search()" placeholder="Suche"/>
<a class="glyphicon glyphicon-remove-sign form-control-feedback form-control-clear" ng-click="ctrl.clearSearch()" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></a>
</div>
As I don't use bootstrap's JavaScript, just the CSS together with Angular, I don't need the classes has-clear and form-control-clear, and I implemented the clear function in my AngularJS controller. With bootstrap's JavaScript this might be possible without own JavaScript.
Base on lonesomeday's answer, I create a jpost
that wraps certain parameters.
$.extend({
jpost: function(url, body) {
return $.ajax({
type: 'POST',
url: url,
data: JSON.stringify(body),
contentType: "application/json",
dataType: 'json'
});
}
});
Usage:
$.jpost('/form/', { name: 'Jonh' }).then(res => {
console.log(res);
});
plt.hist(hmag, 30, range=[6.5, 12.5], facecolor='gray', align='mid')
Native Documents (in which I have an interest) makes a viewer (and editor) specifically for Word documents (both legacy binary .doc and modern docx formats). It does so without lossy conversion to HTML. Here's how to get started https://github.com/NativeDocuments/nd-WordFileEditor/blob/master/README.md
You can truncate all information after the month using date_trunc(text, timestamp)
:
select date_trunc('month',created_at)::date as date
from orders
order by date DESC;
created_at = '2019-12-16 18:28:13'
Output 1:
date_trunc('day',created_at)
// 2019-12-16 00:00:00
Output 2:
date_trunc('day',created_at)::date
// 2019-12-16
Output 3:
date_trunc('month',created_at)::date
// 2019-12-01
Output 4:
date_trunc('year',created_at)::date
// 2019-01-01
This helped me to call API that was using cookie authentication. I have passed authorization in header like this:
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
complete code:
// utility method to read the cookie value:
public static string ReadCookie(string cookieName)
{
var cookies = HttpContext.Current.Request.Cookies;
var cookie = cookies.Get(cookieName);
if (cookie != null)
return cookie.Value;
return null;
}
// using statements where you are creating your webclient
using System.Web.Script.Serialization;
using System.Net;
using System.IO;
// WebClient:
var requestUrl = "<API_url>";
var postRequest = new ClassRoom { name = "kushal seth" };
using (var webClient = new WebClient()) {
JavaScriptSerializer serializer = new JavaScriptSerializer();
byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = requestData.Length;
request.ContentType = "application/json";
request.Expect = "application/json";
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
request.GetRequestStream().Write(requestData, 0, requestData.Length);
using (var response = (HttpWebResponse)request.GetResponse()) {
var reader = new StreamReader(response.GetResponseStream());
var objText = reader.ReadToEnd(); // objText will have the value
}
}
Well, you can create an empty 1-D array using the explicit Array constructor:
a = new Array(9)
To create an array of arrays, I think that you'll have to write a nested loop as Marc described.
In most cases you won't find an Xand, Xor, nor, nand Logical operator in programming, but fear not in most cases you can simulate it with the other operators.
Since you didn't state any particular language. I won't do any specific language either. For my examples we'll use the following variables.
A = 3
B = 5
C = 7
and for code I'll put it in the code tag to make it easier to see what I did, I'll also follow the logic through the process to show what the end result will be.
NAND
Also known as Not And, can easily be simulated by using a Not operator, (normally indicated as ! )
You can do the following
if(!((A>B) && (B<C)))
if (!(F&&T))
if(!(F))
If(T)
In our example above it will be true, since both sides were not true. Thus giving us the desired result
NOR
Also known as Not OR, just like NAND we can simulate it with the not operator.
if(!((A>B) || (B<C)))
if (!(F||T))
if(!(T))
if(F)
Again this will give us the desired outcomes
XOR
Xor or Exlcusive OR only will be true when one is TRUE but the Other is FALSE
If (!(A > C && B > A) && (A > C || B > A) )
If (!(F && T) && (F || T) )
If (!(F) && (T) )
If (T && T )
If (T)
So that is an example of it working for just 1 or the other being true, I'll show if both are true it will be false.
If ( !(A < C && B > A) && (A < C || B > A) )
If ( !(T && T) && (T ||T) )
If ( !(T) && (T) )
If ( F && T )
If (F)
And both false
If (!(A > C && B < A) && (A > C || B < A) )
If (!(F && F) && (F || F) )
If (!(F) && (F) )
If (T && F )
If (F)
XAND
And finally our Exclusive And, this will only return true if both are sides are false, or if both are true. Of course You could just call this a Not XOR (NXOR)
Both True
If ( (A < C && B > A) || !(A < C || B > A) )
If ((T&&T) || !(T||T))
IF (T || !T)
If (T || F)
IF (T)
Both False
If ( (A > C && B < A) || !(A > C || B < A) )
If ( (F && F) || !(F ||F))
If ( F || !F)
If ( F || T)
If (T)
And lastly 1 true and the other one false.
If ((A > C && B > A) || !(A > C || B > A) )
If ((F && T) || ! (F || T) )
If (F||!(T))
If (F||F)
If (F)
Or if you want to go the NXOR route...
If (!(!(A > C && B > A) && (A > C || B > A)))
If (!(!(F && T) && (F || T)) )
If (!(!(F) && (T)) )
If (!(T && T) )
If (!(T))
If (F)
Of course everyone else's solutions probably state this as well, I am putting my own answer in here because the top answer didn't seem to understand that not all languages support XOR or XAND for example C uses ^ for XOR and XAND isn't even supported.
So I provided some examples of how to simulate it with the basic operators in the event your language doesn't support XOR or XAND as their own operators like Php if ($a XOR $B)
.
As for Xnot what is that? Exclusive not? so not not? I don't know how that would look in a logic gate, I think it doesn't exist. Since Not just inverts the output from a 1 to a 0 and 0 to a 1.
Anyway hope that helps.
For WEB API 2.0:
I had to use Request.Content.Headers
instead of Request.Headers
and then i declared an extestion as below
/// <summary>
/// Returns an individual HTTP Header value
/// </summary>
/// <param name="headers"></param>
/// <param name="key"></param>
/// <returns></returns>
public static string GetHeader(this HttpContentHeaders headers, string key, string defaultValue)
{
IEnumerable<string> keys = null;
if (!headers.TryGetValues(key, out keys))
return defaultValue;
return keys.First();
}
And then i invoked it by this way.
var headerValue = Request.Content.Headers.GetHeader("custom-header-key", "default-value");
I hope it might be helpful
I am also facing the same issue and got the resolution after a day :
The exception is coming because System needs Geckodriver to run the Selenium test case. You can try this code under the main Method in Java
System.setProperty("webdriver.gecko.driver","path of/geckodriver.exe");
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);
For more information You can go to this https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver link.
Please let me know if the issue doesn't get resolved.
There is also an 'E' status
E = File existed before update
This can happen if you have manually created a folder that would have been created by performing an update.
If you do know the maximal length of a line, you can do
def getLastLine(fname, maxLineLength=80):
fp=file(fname, "rb")
fp.seek(-maxLineLength-1, 2) # 2 means "from the end of the file"
return fp.readlines()[-1]
This works on my windows machine. But I do not know what happens on other platforms if you open a text file in binary mode. The binary mode is needed if you want to use seek().
I am running CentOS 5.6 as my development environment and the following worked for me.
su -
pecl install ssh2
echo "extension=ssh2.so" > /etc/php.d/ssh2.ini
/etc/init.d/httpd restart
I had the same problem and my solution was:
Go to "Turn Windows features on or off" > Internet Information Services > World Wide Web Services > Application Development Features >Enable ASP.NET 4.5
