with r55 you have to change
rotationMatrix.multiplySelf( object.matrix );
to
rotationMatrix.multiply( object.matrix );
I'd also like to add that if using the three.js editor don't forget to set the background colour to clear as well in the index.html.
background-color:#00000000
Andrea solution is absolutely right, I will just write another implementation based on the same idea. If you took a look at the THREE.ImageUtils.loadTexture() source you will find it uses the javascript Image object. The $(window).load event is fired after all Images are loaded ! so at that event we can render our scene with the textures already loaded...
CoffeeScript
$(document).ready ->
material = new THREE.MeshLambertMaterial(map: THREE.ImageUtils.loadTexture("crate.gif"))
sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material)
$(window).load ->
renderer.render scene, camera
JavaScript
$(document).ready(function() {
material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("crate.gif") });
sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material);
$(window).load(function() {
renderer.render(scene, camera);
});
});
Thanks...
I started to save this as a function, and call it as needed for whatever reactions require it:
function Remove(){
while(scene.children.length > 0){
scene.remove(scene.children[0]);
}
}
Now you can call the Remove(); function where appropriate.
My crystal ball says that you are loading the model using either file://
or C:/
, which stays true to the error message as they are not http://
So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp
and change the url to http://example.com/path/to/model
Origin is defined in RFC-6454 as
...they have the same
scheme, host, and port. (See Section 4 for full details.)
So even though your file originates from the same host (localhost
), but as long as the scheme is different (http
/ file
), they are treated as different origin.
take a look at the following examples
http://threejs.org/examples/#misc_controls_orbit
http://threejs.org/examples/#misc_controls_trackball
there are other examples for different mouse controls, but both of these allow the camera to rotate around a point and zoom in and out with the mouse wheel, the main difference is OrbitControls enforces the camera up direction, and TrackballControls allows the camera to rotate upside-down.
All you have to do is include the controls in your html document
<script src="js/OrbitControls.js"></script>
and include this line in your source
controls = new THREE.OrbitControls( camera, renderer.domElement );
Pretty much. One small difference though: if the Task
fails, GetResult()
will just throw the exception caused directly, while Task.Result
will throw an AggregateException
. However, what's the point of using either of those when it's async
? The 100x better option is to use await
.
Also, you're not meant to use GetResult()
. It's meant to be for compiler use only, not for you. But if you don't want the annoying AggregateException
, use it.
public bool VailidateEntriesForAccount()
{
if (!(txtMailId.Text.Trim() == string.Empty))
{
if (!IsEmail(txtMailId.Text))
{
Logger.Debug("Entered invalid Email ID's");
MessageBox.Show("Please enter valid Email Id's" );
txtMailId.Focus();
return false;
}
}
}
private bool IsEmail(string strEmail)
{
Regex validateEmail = new Regex("^[\\W]*([\\w+\\-.%]+@[\\w\\-.]+\\.[A-Za-z] {2,4}[\\W]*,{1}[\\W]*)*([\\w+\\-.%]+@[\\w\\-.]+\\.[A-Za-z]{2,4})[\\W]*$");
return validateEmail.IsMatch(strEmail);
}
$('#loginBtn').click(function(e) {
e.preventDefault(); /// it should not have this code or else it wont continue

Looks to be more efficient to add the recognizer directly to the cell as shown here:

I expanded one of the answers, however my functionality is a bit different. In my version, different rows form different groups. And "header" row triggers collapsing/expanding of that particular group. Also, each individual subgroup memorizes state that its in. It might sound a bit confusing, you can test drive my version using jsfiddle. Hope this code snippets will be helpful to someone out there!

First thing, for me ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 worked instead of Ssl3.
Secondly, I had to send the Basic Auth request along with some data (form-urlencoded). Here is the complete sample which worked for me perfectly, after trying many solutions.
Disclaimer: The code below is a mixture of solutions found on this link and some other stackoverflow links, thanks for the useful information.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
String username = "user_name";
String password = "password";
String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(username + ":" + password));
//Form Data
var formData = "var1=val1&var2=val2";
var encodedFormData = Encoding.ASCII.GetBytes(formData);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("THE_URL");
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
request.ContentLength = encodedFormData.Length;
request.Headers.Add("Authorization", "Basic " + encoded);
request.PreAuthenticate = true;
using (var stream = request.GetRequestStream())
{
stream.Write(encodedFormData, 0, encodedFormData.Length);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
Try this:
Open PgAdmin -> Files -> Open pgpass.conf
You would get the path of pgpass.conf
at the bottom of the window.
Go to that location and open this file, you can find your password there.
If the above does not work, you may consider trying this:
1. edit pg_hba.conf to allow trust authorization temporarily
2. Reload the config file (pg_ctl reload)
3. Connect and issue ALTER ROLE / PASSWORD to set the new password
4. edit pg_hba.conf again and restore the previous settings
5. Reload the config file again
I use a combination of add()
and endOf()

//...

if (date < tomorrow) return 'tomorrow'

The asker's original inclination to use str.charCodeAt(i)
appears to be faster than the regular expression alternative. In my test on jsPerf the RegExp option performs 66% slower in Chrome 36 (and slightly slower in Firefox 31).
Here's a cleaned-up version of the original validation code that receives a string and returns true
or false
:
function isAlphaNumeric(str) {
var code, i, len;
for (i = 0, len = str.length; i < len; i++) {
code = str.charCodeAt(i);
if (!(code > 47 && code < 58) && // numeric (0-9)
!(code > 64 && code < 91) && // upper alpha (A-Z)
!(code > 96 && code < 123)) { // lower alpha (a-z)
return false;
}
}
return true;
};
Of course, there may be other considerations, such as readability. A one-line regular expression is definitely prettier to look at. But if you're strictly concerned with speed, you may want to consider this alternative.
I configured the app.config

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.
To solve your requirement, here is the working solution -
First create your ViewModels in following way. PersonModel can have list of RoleModels.
public class PersonModel
{
public List<RoleModel> Roles { get; set; }
public string Name { get; set; }
}
public class RoleModel
{
public string RoleName { get; set;}
public string Description { get; set;}
}
Then have a index action which will be serving basic index view -
public ActionResult Index()
{
return View();
}
Index view will be having following JQuery AJAX POST operation -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
$(function () {
$('#click1').click(function (e) {
var jsonObject = {
"Name" : "Rami",
"Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
};
$.ajax({
url: "@Url.Action("AddUser")",
type: "POST",
data: JSON.stringify(jsonObject),
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (response) {
alert(response.responseText);
},
success: function (response) {
alert(response);
}
});
});
});
</script>
<input type="button" value="click1" id="click1" />
Index action posts to AddUser action -
[HttpPost]
public ActionResult AddUser(PersonModel model)
{
if (model != null)
{
return Json("Success");
}
else
{
return Json("An Error Has occoured");
}
}
So now when the post happens you can get all the posted data in the model parameter of action.
Update:
For asp.net core, to get JSON data as your action parameter you should add the [FromBody]
attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController]
attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)
i think you should link your project in console mode
just press Ctrl+h and in General tab select console.
The characters '<', and '>', are to indicate a place-holder, you should remove them to read:
php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME
The only improvement I can see to your own example is using awk which will reduce the number of processes that are run and the amount of data that is piped between them:
/bin/rm output 2> /dev/null
cols=`head -n 1 input | wc -w`
for (( i=1; i <= $cols; i++))
do
awk '{printf ("%s%s", tab, $'$i'); tab="\t"} END {print ""}' input
done >> output
It might be possible that you have not installed the code in your system. So, please install it first. the command is here -
sudo snap install --classic code

Try this extension method out. Hopefully this could help.
public static class DistinctHelper
{
public static IEnumerable<TSource> DistinctBy<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)
{
var identifiedKeys = new HashSet<TKey>();
return source.Where(element => identifiedKeys.Add(keySelector(element)));
}
}
Usage:
var outputList = sourceList.DistinctBy(x => x.TargetProperty);
In case you had to deal with a lot of subfolders contatining subfolders and other recursive stuff. Small improvment of @Mike L'Angelo:
$mypath = "path_to_folder"
$myacl = Get-Acl $mypath
$myaclentry = "username","FullControl","Allow"
$myaccessrule = New-Object System.Security.AccessControl.FileSystemAccessRule($myaclentry)
$myacl.SetAccessRule($myaccessrule)
Get-ChildItem -Path "$mypath" -Recurse -Force | Set-Acl -AclObject $myacl -Verbose
Verbosity is optional in the last line
if you use external libraries in your program and you try to pack all together in a jar file it's not that simple, because of classpath issues etc.
I'd prefer to use OneJar for this issue.
You're almost correct, just misplaced a few quotes. Wrapping the whole thing in regular quotes will literally give you the string #demo + {this.state.id}
- you need to indicate which are variables and which are string literals. Since anything inside {}
is an inline JSX expression, you can do:
href={"#demo" + this.state.id}
This will use the string literal #demo
and concatenate it to the value of this.state.id
. This can then be applied to all strings. Consider this:
var text = "world";
And this:
{"Hello " + text + " Andrew"}
This will yield:
Hello world Andrew
You can also use ES6 string interpolation/template literals with ` (backticks) and ${expr}
(interpolated expression), which is closer to what you seem to be trying to do:
href={`#demo${this.state.id}`}
This will basically substitute the value of this.state.id
, concatenating it to #demo
. It is equivalent to doing: "#demo" + this.state.id
.
I fixed this problem today.
I hope it helps.
If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents
export JAVA_OPTS="-server -Xmx512m"
For Windows you will need, in setenv.bat, something like
set JAVA_OPTS=-server -Xmx768m
Original answer here
After you run startup.bat
, you can easily confirm the correct settings have been applied provided you have turned @echo
on somewhere in your catatlina.bat
file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"
):
Use a different tool. Something like Wolfram Alpha, Maple, R, Octave, Matlab or any other algebra software package.
As a beginner you should probably not attempt to solve such a non-trivial problem.
Try to pass value a and compare using the equals method like this:
public static void main(String str[]) {
boolean b = str[0].equals("a");
System.out.println(b);
}

Your server's response allows the request to include three specific non-simple headers:
Access-Control-Allow-Headers:origin, x-requested-with, content-type
but your request has a header not allowed by the server's response:
Access-Control-Request-Headers:access-control-allow-origin, content-type
All non-simple headers sent in a CORS request must be explicitly allowed by the Access-Control-Allow-Headers
response header. The unnecessary Access-Control-Allow-Origin
header sent in your request is not allowed by the server's CORS response. This is exactly what the "...not allowed by Access-Control-Allow-Headers
" error message was trying to tell you.
There is no reason for the request to have this header: it does nothing, because Access-Control-Allow-Origin
is a response header, not a request header.
Solution: Remove the setRequestHeader
call that adds a Access-Control-Allow-Origin
header to your request.
x[r,]
where r is the row you're interested in. Try this, for example:
#Add your data
x <- structure(list(A = c(5, 3.5, 3.25, 4.25, 1.5 ),
B = c(4.25, 4, 4, 4.5, 4.5 ),
C = c(4.5, 2.5, 4, 2.25, 3 )
),
.Names = c("A", "B", "C"),
class = "data.frame",
row.names = c(NA, -5L)
)
#The vector your result should match
y<-c(A=5, B=4.25, C=4.5)
#Test that the items in the row match the vector you wanted
x[1,]==y

By reading your exception , It's sure that you forgot to autowire customerService
You should autowire your customerservice .
make following changes in your controller class
@Controller
public class CustomerController{
@Autowired
private Customerservice customerservice;
......other code......
}
Again your service implementation class
write
@Service
public class CustomerServiceImpl implements CustomerService {
@Autowired
private CustomerDAO customerDAO;
......other code......
.....add transactional methods
}
If you are using hibernate make necessary changes in your applicationcontext xml file(configuration of session factory is needed).
you should autowire sessionFactory set method in your DAO mplementation

It's the "null coalescing operator", added in php 7.0. The definition of how it works is:
It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.
So it's actually just isset()
in a handy operator.
Those two are equivalent1:
$foo = $bar ?? 'something';
$foo = isset($bar) ? $bar : 'something';

And original RFC https://wiki.php.net/rfc/isset_ternary
EDIT: As this answer gets a lot of views, little clarification:
1There is a difference: In case of ??
, the first expression is evaluated only once, as opposed to ? :
, where the expression is first evaluated in the condition section, then the second time in the "answer" section.
if you are using vs code terminal you have to use this command
$env:NODE_ENV="production"
You can also do,
getDefaultProps: ->
firstName: 'Rails'
lastName: 'React'
now access, those constant (default value) using
@props.firstName
@props.lastName
Hope this help!!!.
YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

The short answer is no: MySQL does not allow you to add a WHERE
clause to the TRUNCATE
statement. Here's MySQL's documentation about the TRUNCATE
statement.
But the good news is that you can (somewhat) work around this limitation.
Simple, safe, clean but slow solution using DELETE
First of all, if the table is small enough, simply use the DELETE
statement (it had to be mentioned):
1. LOCK TABLE my_table WRITE;
2. DELETE FROM my_table WHERE my_date<DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. UNLOCK TABLES;
The LOCK
and UNLOCK
statements are not compulsory, but they will speed things up and avoid potential deadlocks.
Unfortunately, this will be very slow if your table is large... and since you are considering using the TRUNCATE
statement, I suppose it's because your table is large.
So here's one way to solve your problem using the TRUNCATE
statement:
Simple, fast, but unsafe solution using TRUNCATE
1. CREATE TABLE my_table_backup AS
SELECT * FROM my_table WHERE my_date>=DATE_SUB(NOW(), INTERVAL 1 MONTH);
2. TRUNCATE my_table;
3. LOCK TABLE my_table WRITE, my_table_backup WRITE;
4. INSERT INTO my_table SELECT * FROM my_table_backup;
5. UNLOCK TABLES;
6. DROP TABLE my_table_backup;
Unfortunately, this solution is a bit unsafe if other processes are inserting records in the table at the same time:
TRUNCATE
statement resets the AUTO-INCREMENT
counter to zero. So any record inserted between steps 2 and 3 will have an ID that will be lower than older IDs and that might even conflict with IDs inserted at step 4 (note that the AUTO-INCREMENT
counter will be back to it's proper value after step 4).Unfortunately, it is not possible to lock the table and truncate it. But we can (somehow) work around that limitation using RENAME
.
Half-simple, fast, safe but noisy solution using TRUNCATE
1. RENAME TABLE my_table TO my_table_work;
2. CREATE TABLE my_table_backup AS
SELECT * FROM my_table_work WHERE my_date>DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. TRUNCATE my_table_work;
4. LOCK TABLE my_table_work WRITE, my_table_backup WRITE;
5. INSERT INTO my_table_work SELECT * FROM my_table_backup;
6. UNLOCK TABLES;
7. RENAME TABLE my_table_work TO my_table;
8. DROP TABLE my_table_backup;
This should be completely safe and quite fast. The only problem is that other processes will see table my_table
disappear for a few seconds. This might lead to errors being displayed in logs everywhere. So it's a safe solution, but it's "noisy".
Disclaimer: I am not a MySQL expert, so these solutions might actually be crappy. The only guarantee I can offer is that they work fine for me. If some expert can comment on these solutions, I would be grateful.
Update: Genymotion's 2.5.1 release (https://www.genymotion.com/#!/release-notes/251#251) seems to have fixed this issue. (thanks for the heads up @Roger!)
For those that may be stumbling upon this a bit later, I resolved this by installing VirtualBox 4.3.28 (https://www.virtualbox.org/wiki/Download_Old_Builds_4_3). The new 5.0.0 and 4.3.30 versions didn't work for me with Genymotion 2.5. None of the above solutions worked :(
It's also worth noting that at the time of writing, Genymotion's FAQ states the following:
However, for performance reasons, we recommend using version 4.3.12
You can use dom-to-image library (I'm the maintainer).
Here's how you could approach your problem:
var parent = document.getElementById('my-node-parent');
var node = document.getElementById('my-node');
var canvas = document.createElement('canvas');
canvas.width = node.scrollWidth;
canvas.height = node.scrollHeight;
domtoimage.toPng(node).then(function (pngDataUrl) {
var img = new Image();
img.onload = function () {
var context = canvas.getContext('2d');
context.translate(canvas.width, 0);
context.scale(-1, 1);
context.drawImage(img, 0, 0);
parent.removeChild(node);
parent.appendChild(canvas);
};
img.src = pngDataUrl;
});
This will append all the functions that are defined in your_module in a list.
result=[]
for i in dir(your_module):
if type(getattr(your_module, i)).__name__ == "function":
result.append(getattr(your_module, i))
I tried this code, to retrieve shared preferences from an activity, and could not get it to work:
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
sharedPreferences.getAll();
Log.d("AddNewRecord", "getAll: " + sharedPreferences.getAll());
Log.d("AddNewRecord", "Size: " + sharedPreferences.getAll().size());
Every time I tried, my preferences returned 0, even though I have 14 preferences saved by the preference activity. I finally found the answer. I added this to the preferences in the onCreate section.
getPreferenceManager().setSharedPreferencesName("defaultPreferences");
After I added this statement, my saved preferences returned as expected. I hope that this helps someone else who may experience the same issue that I did.
The answer is no. Keep in mind that in both cases, mdDate.Kind = DateTimeKind.Unspecified
.
Therefore it may be better to do the following:
DateTime myDate = new DateTime(1, 1, 1, 0, 0, 0, DateTimeKind.Utc);
The myDate.Kind
property is readonly, so it cannot be changed after the constructor is called.
W3C make it clear, on the specification about Button element
Button may be seen as a generic class for all kind of Buttons with no default behavior.

self.uiTextView.layer.borderWidth = 0.5
self.txtItemShortDes.layer.borderColor = UIColor(red:205.0/255.0, green:205.0/255.0, blue:205.0/255.0, alpha: 1.0).cgColor
(npm install express
while in the project's root directory)
Your project depends on both express
and ejs
, so you should list them both as dependencies in your package.json
.
That way when you run npm install
in you project directory, it'll install both express
and ejs
, so that var express = require('express')
will be the local installation of express (which knows about the ejs
module that you installed locally) rather than the global one, which doesn't.
In general it's a good idea to explicitly list all dependencies in your package.json
even though some of them might already be globally installed, so you don't have these types of issues.
super
is used to call the constructor
, methods
and properties
of parent class.
Now that Powershell is cross platform, I thought I'd throw its way out there, since I find it to be fairly intuitive and extremely simple.
curl -s 'https://api.github.com/users/lambda' | ConvertFrom-Json
ConvertFrom-Json converts the JSON into a Powershell custom object, so you can easily work with the properties from that point forward. If you only wanted the 'id' property for example, you'd just do this:
curl -s 'https://api.github.com/users/lambda' | ConvertFrom-Json | select -ExpandProperty id
If you wanted to invoke the whole thing from within Bash, then you'd have to call it like this:
powershell 'curl -s "https://api.github.com/users/lambda" | ConvertFrom-Json'
Of course there's a pure Powershell way to do it without curl, which would be:
Invoke-WebRequest 'https://api.github.com/users/lambda' | select -ExpandProperty Content | ConvertFrom-Json
Finally, there's also 'ConvertTo-Json' which converts a custom object to JSON just as easily. Here's an example:
(New-Object PsObject -Property @{ Name = "Tester"; SomeList = @('one','two','three')}) | ConvertTo-Json
Which would produce nice JSON like this:
{
"Name": "Tester",
"SomeList": [
"one",
"two",
"three"
]
}
Admittedly, using a Windows shell on Unix is somewhat sacrilegious but Powershell is really good at some things, and parsing JSON and XML are a couple of them. This the GitHub page for the cross platform version https://github.com/PowerShell/PowerShell
If you have no primary key, You can insert if not exist, then do an update. The table must contain at least one entry before using this.
INSERT INTO Test
(id, name)
SELECT
101 as id,
'Bob' as name
FROM Test
WHERE NOT EXISTS(SELECT * FROM Test WHERE id = 101 and name = 'Bob') LIMIT 1;
Update Test SET id='101' WHERE name='Bob';
If you installed postresql on your server then just host: localhost to database.yml, I usually throw it in around where it says pool: 5. Otherwise if it's not localhost definitely tell that app where to find its database.
development:
adapter: postgresql
encoding: unicode
database: kickrstack_development
host: localhost
pool: 5
username: kickrstack
password: secret
Make sure your user credentials are set correctly by creating a database and assigning ownership to your app's user to establish the connection. To create a new user in postgresql 9 run:
sudo -u postgres psql
set the postgresql user password if you haven't, it's just backslash password.
postgres=# \password
Create a new user and password and the user's new database:
postgres=# create user "guy_on_stackoverflow" with password 'keepitonthedl';
postgres=# create database "dcaclab_development" owner "guy_on_stackoverflow";
Now update your database.yml file after you've confirmed creating the database, user, password and set these privileges. Don't forget host: localhost.
W3Schools have a nice article on this subject.
Scripts in <head>
Scripts to be executed when they are called, or when an event is triggered, are placed in functions.
Put your functions in the head section, this way they are all in one place, and they do not interfere with page content.
Scripts in <body>
If you don't want your script to be placed inside a function, or if your script should write page content, it should be placed in the body section.
If the problem still persists,
Put the- mysql-connector-java-5.0.8-bin jar in a place inside your Tomcat->lib->folder (No matter where you've installed your Tomcat). And change your environmental variable (Done by clicking Properties of Mycomputer -Advanced system settings- Environmental variables-And set a new variable name & variable values as the place where your lib file resides.Dont forget to enter a ; at the end of the path)
If still problem persists Try downloading commons-collections-2.0.jar (http://www.docjar.com/jar_detail/commons-collections-2.0.jar.html) and paste the jar in the same place where your mysql jar resides (ie) inside Tomcat-lib.
Clean your project-Stop your server- Finally try to run.
var val = $('input:checkbox:checked, input:radio:checked, \
select option:selected, textarea, input:text',
$('#container')).val();
Comments:
I assume, that there is exactly one form element, that can be either a textarea, input field, select form, a set of radio buttons or a single checkbox (you will have to update my code if you need more checkboxes).
The element in question lives inside an element with ID container
(to remove ambiguences with other elements on the page).
The code will then return the value of the first matching element it finds. Since I use :checked
and so on, this should always be exactly the value of what you're looking for.
I believe referencing this.state
inside of setState()
is discouraged (State Updates May Be Asynchronous).
The docs recommend using setState()
with a callback function so that prevState is passed in at runtime when the update occurs. So this is how it would look:
Using Array.prototype.filter without ES6
removeItem : function(index) {
this.setState(function(prevState){
return { data : prevState.data.filter(function(val, i) {
return i !== index;
})};
});
}
Using Array.prototype.filter with ES6 Arrow Functions
removeItem(index) {
this.setState((prevState) => ({
data: prevState.data.filter((_, i) => i !== index)
}));
}
Using immutability-helper
import update from 'immutability-helper'
...
removeItem(index) {
this.setState((prevState) => ({
data: update(prevState.data, {$splice: [[index, 1]]})
}))
}
Using Spread
function removeItem(index) {
this.setState((prevState) => ({
data: [...prevState.data.slice(0,index), ...prevState.data.slice(index+1)]
}))
}
Note that in each instance, regardless of the technique used, this.setState()
is passed a callback, not an object reference to the old this.state
;
I think that you'll probably have to use $.ajax()
if you want to change the encoding, see the contentType
param below (the success
and error
callbacks assume you have <div id="success"></div>
and <div id="error"></div>
in the html):
$.ajax({
type: "POST",
url: "SomePage.aspx/GetSomeObjects",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: "{id: '" + someId + "'}",
success: function(json) {
$("#success").html("json.length=" + json.length);
itemAddCallback(json);
},
error: function (xhr, textStatus, errorThrown) {
$("#error").html(xhr.responseText);
}
});
I actually just had to do this about an hour ago, what a coincidence!
There is a gmail API now, which lets you send email, read email and create drafts via REST. Unlike the SMTP calls, it is non-blocking which can be a good thing for thread-based webservers sending email in the request thread (like python webservers). The API is also quite powerful.
It's easiest to setup if you have Google Apps administrator rights on the domain, because then you can give blanket permission to your client. Otherwise you have to fiddle with OAuth authentication and permission.
Here is a gist demonstrating it:
I know that there are accepted answer but still, I want to share my scenario that maybe help someone to solve their problem TOOLS
SCENARIO
i was loading the dataset which's in CSV format which was later to be shown on the View
i tried to use the bulk load but I's unable to load as BULK LOAD
was using
FIELDTERMINATOR = ','
and Excel cell was also using ,
however, I also couldn't use Flat file source
directly because I was using Code-First Approach
and doing that only made model in SSMS DB, not in the model from which I had to use the properties later.

From git reset
"pull" or "merge" always leaves the original tip of the current branch in
ORIG_HEAD
.git reset --hard ORIG_HEAD
Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.
git reset --merge ORIG_HEAD
After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "
git reset --hard ORIG_HEAD
" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge
" keeps your local changes.
Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am
' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).In addition, merge always sets '
.git/ORIG_HEAD
' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD
'.
Note: from here
HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.
So HEAD is NOT a synonym for "current branch" everywhere already.
HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).
But it almost always means the "current commit".
It is the commit "git commit
" builds on top of, and "git diff --cached
" and "git status
" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".
HEAD@{5.minutes.ago}
could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".
git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.
Instead of typing four capital letters "
HEAD
", you can say "@
" now,
e.g. "git log @
".
See commit cdfd948
Typing '
HEAD
' is tedious, especially when we can use '@
' instead.The reason for choosing '
@
' is that it follows naturally from theref@op
syntax (e.g.HEAD@{u}
), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD
'.So now we can use '
git show @~1
', and all that goody goodness.Until now '
@
' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.
Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.
On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.
Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.
os.path.exists(path) Returns True if path refers to an existing path. An existing path can be regular files (http://en.wikipedia.org/wiki/Unix_file_types#Regular_file), but also special files (e.g. a directory). So in essence this function returns true if the path provided exists in the filesystem in whatever form (notwithstanding a few exceptions such as broken symlinks).
os.path.isdir(path) in turn will only return true when the path points to a directory
To compare date only with year - month - day and without time for me worked like this:
let order = Calendar.current.compare(self.startDate, to: compareDate!, toGranularity: .day)
switch order {
case .orderedAscending:
print("\(gpsDate) is after \(self.startDate)")
case .orderedDescending:
print("\(gpsDate) is before \(self.startDate)")
default:
print("\(gpsDate) is the same as \(self.startDate)")
}
String s = "<B><G>Test</G></B><C>Test1</C>";
String pattern ="\\<(.+)\\>([^\\<\\>]+)\\<\\/\\1\\>";
int count = 0;
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(s);
while(m.find())
{
System.out.println(m.group(2));
count++;
}
According to the specification, http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf:
A string is a sequence of Unicode code points wrapped with quotation marks (
U+0022
). All characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark (U+0022
), reverse solidus (U+005C
), and the control charactersU+0000
toU+001F
. There are two-character escape sequence representations of some characters.
So you can't pass 0x0A
or 0x0C
codes directly. It is forbidden! The specification suggests to use escape sequences for some well-defined codes from U+0000
to U+001F
:
\f
represents the form feed character (U+000C
).\n
represents the line feed character (U+000A
).As most of programming languages uses \
for quoting, you should escape the escape syntax (double-escape - once for language/platform, once for JSON itself):
jsonStr = "{ \"name\": \"Multi\\nline.\" }";
There is nothing wrong with the idea of modifying an element inside a list while traversing it (don't modify the list itself, that's not recommended), but it can be better expressed like this:
for (int i = 0; i < letters.size(); i++) {
letters.set(i, "D");
}
At the end the whole list will have the letter "D"
as its content. It's not a good idea to use an enhanced for
loop in this case, you're not using the iteration variable for anything, and besides you can't modify the list's contents using the iteration variable.
Notice that the above snippet is not modifying the list's structure - meaning: no elements are added or removed and the lists' size remains constant. Simply replacing one element by another doesn't count as a structural modification. Here's the link to the documentation quoted by @ZouZou in the comments, it states that:
A structural modification is any operation that adds or deletes one or more elements, or explicitly resizes the backing array; merely setting the value of an element is not a structural modification
You need to give the same style of the fixed element and its parent element. One of these examples is created with max widths and in the other example with paddings.

After generation of woff files, you have to define font-family, which can be used later in all your css styles. Below is the code to define font families (for normal, bold, bold-italic, italic) typefaces. It is assumed, that there are 4 *.woff files (for mentioned typefaces), placed in fonts
subdirectory.
In CSS code:
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font.woff") format('woff');
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-bold.woff") format('woff');
font-weight: bold;
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-boldoblique.woff") format('woff');
font-weight: bold;
font-style: italic;
}
@font-face {
font-family: "myfont";
src: url("fonts/awesome-font-oblique.woff") format('woff');
font-style: italic;
}
After having that definitions, you can just write, for example,
In HTML code:
<div class="mydiv">
<b>this will be written with awesome-font-bold.woff</b>
<br/>
<b><i>this will be written with awesome-font-boldoblique.woff</i></b>
<br/>
<i>this will be written with awesome-font-oblique.woff</i>
<br/>
this will be written with awesome-font.woff
</div>
In CSS code:
.mydiv {
font-family: myfont
}
The good tool for generation woff files, which can be included in CSS stylesheets is located here. Not all woff files work correctly under latest Firefox versions, and this generator produces 'correct' fonts.
bundle install mysql --force
helped me. It reinstalled dependencies which ware gone as a result of brew uninstall mysql
.
I my case the error was a result of me not assigning my return value to a variable. The following caused the error message:
return new JavaScriptSerializer().Serialize("hello");
I changed it to:
string H = "hello";
return new JavaScriptSerializer().Serialize(H);
Without the variable JSON is unable to properly format the data.
You can't according to the PHP manual:
Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.
This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.
But you can work around it by also setting $_COOKIE
when you call setcookie()
:
if(!isset($_COOKIE['lg'])) {
setcookie('lg', 'ro');
$_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];
String.prototype.startsWith = function(needle)

Did you forget to join some tables? If not then you probably need to use some aliases.
To delete the last element of the lists, you could use:
def deleteLast(self):
if self.Ans:
del self.Ans[-1]
if self.masses:
del self.masses[-1]

This is finally what did it for me (and triggers a disposition):

_x000D_
var element = document.getElementById("clickbind");_x000D_
element.addEventListener("click", onClick);
_x000D_

And for those of the KnockoutJS inclination, a little binding:
ko.bindingHandlers.generatePDF = {
init: function(element) {
function onClick() {
var pdf = new jsPDF('p', 'pt', 'letter');
pdf.canvas.height = 72 * 11;
pdf.canvas.width = 72 * 8.5;

pdf.save('test.pdf');
};
element.addEventListener("click", onClick);
}
};
See the Java Persistence book: Identity and Sequencing
The relevant part for your question is the No Primary Key section:
Sometimes your object or table has no primary key. The best solution in this case is normally to add a generated id to the object and table. If you do not have this option, sometimes there is a column or set of columns in the table that make up a unique value. You can use this unique set of columns as your id in JPA. The JPA
Id
does not always have to match the database table primary key constraint, nor is a primary key or a unique constraint required.If your table truly has no unique columns, then use all of the columns as the id. Typically when this occurs the data is read-only, so even if the table allows duplicate rows with the same values, the objects will be the same anyway, so it does not matter that JPA thinks they are the same object. The issue with allowing updates and deletes is that there is no way to uniquely identify the object's row, so all of the matching rows will be updated or deleted.
If your object does not have an id, but its' table does, this is fine. Make the object an
Embeddable
object, embeddable objects do not have ids. You will need aEntity
that contains thisEmbeddable
to persist and query it.
Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.
Simple code example for observing display:none switching:
// Start observing visbility of element. On change, the
// the callback is called with Boolean visibility as
// argument:
function respondToVisibility(element, callback) {
var options = {
root: document.documentElement,
};
var observer = new IntersectionObserver((entries, observer) => {
entries.forEach(entry => {
callback(entry.intersectionRatio > 0);
});
}, options);
observer.observe(element);
}

I also got the following error when I run a command with PHP
, I did the solution like that:
C:\xampp\php
to your PATH Environment Variable.Very important note: restart command prompt
After inspecting an SSIS Package(due to a SQL Server executing commands really slow), that was set up in a client of ours about 5-4 years before the time of me writing this, I found out that there were the below tasks: 1) insert data from an XML file into a table called [Importbarcdes].
2) merge command on an another target table, using as source the above mentioned table.
3) "delete from [Importbarcodes]", to clear the table of the row that was inserted after the XML file was read by the task of the SSIS Package.
After a quick inspection all statements(SELECT, UPDATE, DELETE etc.) on the table ImportBarcodes that had only 1 row, took about 2 minutes to execute.
Extended Events showed a whole lot PAGEIOLATCH_EX wait notifications.
No indexes were present of the table and no triggers were registered.
Upon close inspection of the properties of the table, in the Storage Tab and under general section, the Data Space field showed more than 6 GIGABYTES of space allocated in pages.
What happened:
The query ran for a good portion of time each day for the last 4 years, inserting and deleting data in the table, leaving unused pagefiles behind with out freeing them up.
So, that was the main reason of the wait events that were captured by the Extended Events Session and the slowly executed commands upon the table.
Running ALTER TABLE ImportBarcodes REBUILD
fixed the issue freeing up all the unused space. TRUNCATE TABLE ImportBarcodes
did a similar thing, with the only difference of deleting all pagefiles and data.
You can do this in jquery by setting the attribute disabled to 'disabled'.
$(this).prop('disabled', true);
I have made a simple example http://jsfiddle.net/4gnXL/2/
The above answers are good and you can do it in a simple way also.
You can use the recursive method calls.
func vibrateTheDeviceContinuously() throws {
// Added concurrent queue for next & Vibrate device
DispatchQueue.global(qos: .utility).async {
//Vibrate the device
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
self.incrementalCount += 1
usleep(800000) // if you don't want, remove this line.
do {
if let isKeepBuzzing = self.iShouldKeepBuzzing , isKeepBuzzing == true {
try self.vibrateTheDeviceContinuously()
}
else {
return
}
} catch {
//Exception handle
print("exception")
}
}
}
To stop the device vibration use the following line.
self.iShouldKeepBuzzing = false
I also have the problem but now solved
$cfg['Servers'][$i]['user'] = 'admin';
- I change the user name from 'root' to 'admin'
Use grep and regular expressions, for example if you want 4 minutes interval of logs:
grep "31/Mar/2002:19:3[1-5]" logfile
will return all logs lines between 19:31 and 19:35 on 31/Mar/2002. Supposing you need the last 5 days starting from today 27/Sep/2011 you may use the following:
grep "2[3-7]/Sep/2011" logfile
In case the OP wants to squash the 2 commits specified into 1, here is an alternate way to do it without rebasing
git checkout HEAD^ # go to the first commit you want squashed
git reset --soft HEAD^ # go to the second one but keep the tree and index the same
git commit --amend -C HEAD@{1} # use the message from first commit (omit this to change)
git checkout HEAD@{3} -- . # get the tree from the commit you did not want to touch
git add -A # add everything
git commit -C HEAD@{3} # commit again using the message from that commit
The @{N)
syntax is handy to know as it will allow you to reference the history of where your references were. In this case it's HEAD which represents your current commit.
Use below if you need to empty Angular 2+ FormArray.
public emptyFormArray(formArray:FormArray) {
for (let i = formArray.controls.length - 1; i >= 0; i--) {
formArray.removeAt(i);
}
}
Can you use boost?
samm$ cat split.cc
#include <boost/algorithm/string/classification.hpp>

boost::split( tokens, split_me, boost::is_any_of(" ") );
std::cout << tokens.size() << " tokens" << std::endl;
BOOST_FOREACH( const std::string& i, tokens ) {
std::cout << "'" << i << "'" << std::endl;
}
}
sample execution:
samm$ ./a.out

For Developer certificate, you need to create a developer .mobileprovision profile and install add it to your XCode. In case you want to distribute the app using an adhoc distribution profile you will require AdHoc Distribution certificate and private key installed in your keychain.
If you have not created the cert, here are steps to create it. Incase it has already been created by someone in your team, ask him to share the cert and private key. If that someone is no longer in your team then you can revoke the cert from developer account and create new.
I know it is a bit picky, but all the answers so far are not quite right.
The point of path.join() is to eliminate the need for the caller to know which directory separator to use (making code platform agnostic).
Technically the correct answer would be something like:
var path = require("path");
fs.readFile(path.join(__dirname, '..', '..', 'foo.bar'));
I would have added this as a comment to Alex Wayne's answer but not enough rep yet!
EDIT: as per user1767586's observation
def train_val_test_split(X, y, train_size, val_size, test_size):
X_train_val, X_test, y_train_val, y_test = train_test_split(X, y, test_size = test_size)
relative_train_size = train_size / (val_size + train_size)
X_train, X_val, y_train, y_val = train_test_split(X_train_val, y_train_val,
train_size = relative_train_size, test_size = 1-relative_train_size)
return X_train, X_val, X_test, y_train, y_val, y_test
Here we split data 2 times with sklearn's train_test_split
For DB2:
`VALUES('Hello world')`
You can do multiple "rows" as well:
`VALUES('Hello world'),('Goodbye world');`
You can even use them in joins as long as the types match:
VALUES(1,'Hello world')
UNION ALL
VALUES(2,'Goodbye world');
Try doing this, there's no special character to concatenate in bash :
mystring="${arg1}12${arg2}endoffile"
If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile
(I guess that's not what you asked) like in the following example :
mystring="$arg112$arg2endoffile"
The brackets are delimiters for the variables when needed. When not needed, you can use it or not.
bash
> 3.1)
$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile
To use session variables, it's necessary to start the session by using the session_start
function, this will allow you to store your data in the global variable $_SESSION
in a productive way.
so your code will finally look like this :
<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>
<?php
// starting the session
session_start();
if (isset($_POST['Submit'])) {
$_SESSION['picturenum'] = $_POST['picturenum'];
}
?>
<strong><?php echo $_SESSION['picturenum'];?></strong>
to make it easy to use and to avoid forgetting it again, you can create a session_file.php
which you will want to be included in all your codes and will start the session for you:
session_start.php
<?php
session_start();
?>
and then include it wherever you like :
<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>
<?php
// including the session file
require_once("session_start.php");
if (isset($_POST['Submit'])) {
$_SESSION['picturenum'] = $_POST['picturenum'];
}
?>
that way it is more portable and easy to maintain in the future.
other remarks
if you are using Apache version 2 or newer, be careful. instead of
<?
to open php's tags, use
<?php
, otherwise your code will not be interpreted
variables names in php are case-sensitive, instead of write $_session, write $_SESSION in capital letters
good work!
The properties center
, bounds
and frame
are interlocked: changing one will update the others, so use them however you want. For example, instead of modifying the x/y params of frame
to recenter a view, just update the center
property.
You should create the media
dir appended to what getLocalPath()
returns.
This is preferred approach in most cases:
File.open(yourfile, 'w') { |file| file.write("your text") }
When a block is passed to File.open
, the File object will be automatically closed when the block terminates.
If you don't pass a block to File.open
, you have to make sure that file is correctly closed and the content was written to file.
begin
file = File.open("/tmp/some_file", "w")
file.write("your text")
rescue IOError => e
#some error occur, dir not writable etc.
ensure
file.close unless file.nil?
end
You can find it in documentation:
static VALUE rb_io_s_open(int argc, VALUE *argv, VALUE klass)
{
VALUE io = rb_class_new_instance(argc, argv, klass);
if (rb_block_given_p()) {
return rb_ensure(rb_yield, io, io_close, io);
}
return io;
}
Get-Member
is a cmdlet for listing the members of a .NET object
. This has nothing to do with user/group membership. You can get the current user's group membership like so:
PS> [System.Security.Principal.WindowsIdentity]::GetCurrent().Groups |
Format-Table -auto
BinaryLength AccountDomainSid Value

If you need access to arbitrary users' group info then @tiagoinu suggestion of using the Quest AD cmdlets is a better way to go.
I just first increased the
"index.number_of_replicas"
by 1 (wait until nodes are synced) then decreased it by 1 afterwards, which effectively removes the unassigned shards and cluster is Green again without the risk of losing any data.
I believe there are better ways but this is easier for me.
Hope this helps.
With Jeffrey Fox's interpretation about no-cache
, i've tested under chrome 52.0.2743.116 m, the result shows that no-cache
has the same behavior as must-revalidate
, they all will NOT use local cache when server is unreachable, and, they all will use cache while tap browser's Back/Forward button when server is unreachable.
As above, i think max-age=0, must-revalidate
is identical to no-cache
, at least in implementation.
You can use the recode
function from dplyr
.
df <- iris %>%
mutate(Species = recode(Species, setosa = "SETOSA",
versicolor = "VERSICOLOR",
virginica = "VIRGINICA"
)
)
A const
to a pointer indicates a "read-only" memory location. Whereas the ones without const
are a read-write memory areas. So, you "cannot" convert a const
(read-only location) to a normal(read-write) location.
The alternate is to copy the data to a different read-write location and pass this pointer to the required function. You may use strdup()
to perform this action.
When you extract a single row from a data frame you get a one-row data frame. Convert it to a numeric vector:
as.numeric(df[1,])
As @Roland suggests, unlist(df[1,])
will convert the one-row data frame to a numeric vector without dropping the names. Therefore unname(unlist(df[1,]))
is another, slightly more explicit way to get to the same result.
As @Josh comments below, if you have a not-completely-numeric (alphabetic, factor, mixed ...) data frame, you need as.character(df[1,])
instead.
The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content
StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();
To navigate through the all inputs
foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
string value = HttpContext.Current.Request.Form[key];
}
The above answers are good, but in half of these you won't be getting 404 as your HTTP status code returned and in other half, you won't be able to have a custom template render. The best way to have a custom error page (404's) in Expressjs is
app.use(function(req, res, next){
res.status(404).render('404_error_template', {title: "Sorry, page not found"});
});
Place this code at the end of all your URL mappings.
You called an incorrect method of String class, try:
int tmpInt = 10;
String tmpStr10 = String.valueOf(tmpInt);
You can also do:
int tmpInt = 10;
String tmpStr10 = Integer.toString(tmpInt);
In the Edge browser as of build 20.10240.16384.0 you can hide the address bar by setting location=no in the window.open features.
I have tried all the solutions here and none of them have worked yet. A workaround that is working is to Click Connect, enter the server name, select Options, Connection Properties tab. Set the "Network protocol" to "Named Pipes". This allows users to remote connect using their network credentials. I'll post an update when I get a fix.
In rails 4.2 the above methods didn't work.

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:
Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();
This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.
It was a limitation of the technology at the time it was created. My answer copied over from Programmers.SE:
From one of the original HTML drafts:
NOTE: In the initial design for forms, multi-line text fields were supported by the Input element with TYPE=TEXT. Unfortunately, this causes problems for fields with long text values. SGML's default (Reference Quantity Set) limits the length of attribute literals to only 240 characters. The HTML 2.0 SGML declaration increases the limit to 1024 characters.
I have used sub-query and it worked great!

DISTINCT is not a function that applies only to some columns. It's a query modifier that applies to all columns in the select-list.
That is, DISTINCT reduces rows only if all columns are identical to the columns of another row.
DISTINCT must follow immediately after SELECT (along with other query modifiers, like SQL_CALC_FOUND_ROWS). Then following the query modifiers, you can list columns.
RIGHT: SELECT DISTINCT foo, ticket_id FROM table...
Output a row for each distinct pairing of values across ticket_id and foo.
WRONG: SELECT foo, DISTINCT ticket_id FROM table...
If there are three distinct values of ticket_id, would this return only three rows? What if there are six distinct values of foo? Which three values of the six possible values of foo should be output?
It's ambiguous as written.
Here's a slightly less complicated answer:
NSString *myString = @"abcdefg";
NSString *mySmallerString = [myString substringToIndex:4];

In case you happen to use additional stuff like dependsOnMethods
, you may want to define the entire @Test flow in your testng.xml file. AFAIK, the order defined in your suite XML file (testng.xml) will override all other ordering strategies.
Use Object.keys
:
var foo = {_x000D_
'alpha': 'puffin',_x000D_
'beta': 'beagle'_x000D_
};_x000D_
_x000D_
var keys = Object.keys(foo);_x000D_
console.log(keys) // ['alpha', 'beta'] _x000D_
// (or maybe some other order, keys are unordered).
_x000D_
This is an ES5 feature. This means it works in all modern browsers but will not work in legacy browsers.
The ES5-shim has a implementation of Object.keys

You may need administrator privileges for step 5. What you do here thus depends on your operating system. For example in Ubuntu you would say sudo python setup.py install
EDIT- thanks to kwatford (see first comment)
To bypass the need for administrator privileges during step 5 above you may be able to make use of the --user flag. In this way you can install the package only for the current user.
The docs say:
Files will be installed into subdirectories of site.USER_BASE (written as userbase hereafter). This scheme installs pure Python modules and extension modules in the same location (also known as site.USER_SITE). Here are the values for UNIX, including Mac OS X:

(with a trailing dash) to ignore leading tabs (but not leading spaces).
For example this:
if [ some test ]; then
cat <<- xx
line1
line2
xx
fi
Outputs indented text without the leading whitespace:
line1
line2
The error usually means that the port you are trying to open is being already used by another application. Try using netstat to see which ports are open and then use an available port.
Also check if you are binding to the right ip address (I am assuming it would be localhost)
ng serve works for serving our application for development purposes. What about for production? If we look into our package.json file, we can see that there are scripts we can use:
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build --prod",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
The build script uses the Angular CLI's ng build with the --prod flag. Let's try that now. We can do it one of two ways:
# using the npm scripts
npm run build
# using the cli directly
ng build --prod
This time we are given four files instead of the five. The --prod flag tells Angular to make our application much smaller in size.
method 1 <input type="text" onclick="this.disabled=false;" disabled>
<hr>
method 2 <input type="text" onclick="this.removeAttribute('disabled');" disabled>
<hr>
method 3 <input type="text" onclick="this.removeAttribute('readonly');" readonly>
code of the previous answers don't seem to work in inline mode, but there is a workaround: method 3.
select distinct a.FirstName, a.LastName, v.District from AddTbl a inner join ValTbl v on a.LastName = v.LastName order by a.FirstName;
hope this helps
Here's an updated example using Angular 4 (also compatible with Angular 5 - 8)
Routes with home route protected by AuthGuard
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './login/index';
import { HomeComponent } from './home/index';
import { AuthGuard } from './_guards/index';
const appRoutes: Routes = [
{ path: 'login', component: LoginComponent },
// home route protected by auth guard
{ path: '', component: HomeComponent, canActivate: [AuthGuard] },
// otherwise redirect to home
{ path: '**', redirectTo: '' }
];
export const routing = RouterModule.forRoot(appRoutes);
AuthGuard redirects to login page if user isn't logged in
Updated to pass original url in query params to login page
import { Injectable } from '@angular/core';
import { Router, CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
@Injectable()
export class AuthGuard implements CanActivate {
constructor(private router: Router) { }
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
if (localStorage.getItem('currentUser')) {
// logged in so return true
return true;
}
// not logged in so redirect to login page with the return url
this.router.navigate(['/login'], { queryParams: { returnUrl: state.url }});
return false;
}
}

The kind() function from Agave.JS will return:
It works on all JS objects and primitives, regardless of how they were created, and doesn't have any surprises. Examples:
kind(37) === 'Number'
kind(3.14) === 'Number'
kind(Math.LN2) === 'Number'
kind(Infinity) === 'Number'
kind(Number(1)) === 'Number'
kind(new Number(1)) === 'Number'
kind(NaN) === 'NaN'
kind('') === 'String'
kind('bla') === 'String'
kind(String("abc")) === 'String'
kind(new String("abc")) === 'String'
kind(true) === 'Boolean'
kind(false) === 'Boolean'
kind(new Boolean(true)) === 'Boolean'
kind([1, 2, 4]) === 'Array'
kind(new Array(1, 2, 3)) === 'Array'
kind({a:1}) === 'Object'
kind(new Object()) === 'Object'
kind(new Date()) === 'Date'
kind(function(){}) === 'Function'
kind(new Function("console.log(arguments)")) === 'Function'
kind(Math.sin) === 'Function'
kind(undefined) === 'undefined'
kind(null) === 'null'
This is similar to some of the above answers, but with this, you can specify if you want to remove rows with a percentage of missing values greater-than or equal-to a given percent (with the argument pct
)
drop_rows_all_na <- function(x, pct=1) x[!rowSums(is.na(x)) >= ncol(x)*pct,]
Where x
is a dataframe and pct
is the threshold of NA
-filled data you want to get rid of.
pct = 1
means remove rows that have 100% of its values NA
.
pct = .5
means remome rows that have at least half its values NA
Quick & dirty:
function getObjName(obj) {
return (wrap={obj}) && eval('for(p in obj){p}') && (wrap=null);
}
CONVERT
style 103 is dd/mm/yyyy. Then use the REPLACE
function to eliminate the slashes.
SELECT REPLACE(CONVERT(CHAR(10), [MyDateTime], 103), '/', '')
In case you don't want to get mad with spaces in arguments and want to use variables try this:
objshell.run "cscript ""99 Writelog.vbs"" /r:" & r & " /f:""" & wscript.scriptname & """ /c:""" & c & ""
where
r=123
c="Whatever comment you like"
You are trying to access a member of a structure, but in something that is not a structure. For example:
struct {
int a;
int b;
} foo;
int fum;
fum.d = 5;
see the picture. but I have to type enough chars to post the picture.:)
U can try java.util.Date
library like this way-
int no_of_day_to_add = 1;
Date today = new Date();
Date tomorrow = new Date( today.getYear(), today.getMonth(), today.getDate() + no_of_day_to_add );
Change value of no_of_day_to_add
as you want.
I have set value of no_of_day_to_add
to 1
because u wanted only one day to add.
More can be found in this documentation.
The build context menu has a Cancel build in Visual Studio 2013.
Try:
<xsl:value-of select="count(preceding-sibling::*) + 1" />
Edit - had a brain freeze there, position() is more straightforward!
Why you make it so hard to understand?
function table_exist($table){
$pTableExist = mysql_query("show tables like '".$table."'");
if ($rTableExist = mysql_fetch_array($pTableExist)) {
return "Yes";
}else{
return "No";
}
}
I think i am understanding your question. This filters things that are in the column labels or the row labels. The last 2 sections of the code is what you want but im pasting everything so that you can see exactly how It runs start to finish with everything thats defined etc. I definitely took some of this code from other sites fyi.
Near the end of the code, the "WardClinic_Category" is a column of my data and in the column label of the pivot table. Same for the IVUDDCIndicator (its a column in my data but in the row label of the pivot table).
Hope this helps others...i found it very difficult to find code that did this the "proper way" rather than using code similar to the macro recorder.

I had problem like this, but with several "actions". My solution looks like this:
<form method="POST" th:object="${searchRequest}" action="searchRequest" >
<input type="text" th:field="*{name}"/>
<input type="submit" value="find" th:value="find" />
</form>
...
<form method="POST" th:object="${commodity}" >
<input type="text" th:field="*{description}"/>
<input type="submit" value="add" />
</form>
And controller
@Controller
@RequestMapping("/goods")
public class GoodsController {
@RequestMapping(value = "add", method = GET)
public String showGoodsForm(Model model){
model.addAttribute(new Commodity());
model.addAttribute("searchRequest", new SearchRequest());
return "goodsForm";
}
@RequestMapping(value = "add", method = POST)
public ModelAndView processAddCommodities(
@Valid Commodity commodity,
Errors errors) {
if (errors.hasErrors()) {
ModelAndView model = new ModelAndView("goodsForm");
model.addObject("searchRequest", new SearchRequest());
return model;
}
ModelAndView model = new ModelAndView("redirect:/goods/" + commodity.getName());
model.addObject(new Commodity());
model.addObject("searchRequest", new SearchRequest());
return model;
}
@RequestMapping(value="searchRequest", method=POST)
public String processFindCommodity(SearchRequest commodity, Model model) {
...
return "catalog";
}
I'm sure - here is not "best practice", but it is works without "Neither BindingResult nor plain target object for bean name available as request attribute".
To rename file using refactoring (which also updates all occurrences of name in other scripts):
See "PHP Developer User Guide > Tasks > Using Refactoring > Renaming Files".
When you see "import: command not found" on the very first import, it is caused by the parser not using the character encoding matching your py file. Especially when you are not using ASCII encoding in your py file.
The way to get it right is to specify the correct encoding on top of your py file to match your file character encoding.
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import os
no... Once u have executed the statement anotherList.addAll(list) and after that if u change some list data it does not carry to another list
I've created some solution to make any-color themes, maybe this can be useful for somebody. API 9+
1. first create "res/values-v9/" and put there this file: styles.xml and regular "res/values" folder will be used with your styles.
2. put this code in your res/values/styles.xml:
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#000</item>
<item name="colorPrimaryDark">#000</item>
<item name="colorAccent">#000</item>
<item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>
</style>
<style name="AppThemeDarkActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#000</item>
<item name="colorPrimaryDark">#000</item>
<item name="colorAccent">#000</item>
<item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>
</style>
<style name="WindowAnimationTransition">
<item name="android:windowEnterAnimation">@android:anim/fade_in</item>
<item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>
</resources>
3. in to AndroidManifest:
<application android:theme="@style/AppThemeDarkActionBar">
4. create a new class with name "ThemeColors.java"
public class ThemeColors {
private static final String NAME = "ThemeColors", KEY = "color";
@ColorInt
public int color;
public ThemeColors(Context context) {
SharedPreferences sharedPreferences = context.getSharedPreferences(NAME, Context.MODE_PRIVATE);
String stringColor = sharedPreferences.getString(KEY, "004bff");
color = Color.parseColor("#" + stringColor);
if (isLightActionBar()) context.setTheme(R.style.AppTheme);
context.setTheme(context.getResources().getIdentifier("T_" + stringColor, "style", context.getPackageName()));
}
public static void setNewThemeColor(Activity activity, int red, int green, int blue) {
int colorStep = 15;
red = Math.round(red / colorStep) * colorStep;
green = Math.round(green / colorStep) * colorStep;
blue = Math.round(blue / colorStep) * colorStep;
String stringColor = Integer.toHexString(Color.rgb(red, green, blue)).substring(2);
SharedPreferences.Editor editor = activity.getSharedPreferences(NAME, Context.MODE_PRIVATE).edit();
editor.putString(KEY, stringColor);
editor.apply();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) activity.recreate();
else {
Intent i = activity.getPackageManager().getLaunchIntentForPackage(activity.getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
activity.startActivity(i);
}
}
private boolean isLightActionBar() {// Checking if title text color will be black
int rgb = (Color.red(color) + Color.green(color) + Color.blue(color)) / 3;
return rgb > 210;
}
}
5. MainActivity:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new ThemeColors(this);
setContentView(R.layout.activity_main);
}
public void buttonClick(View view){
int red= new Random().nextInt(255);
int green= new Random().nextInt(255);
int blue= new Random().nextInt(255);
ThemeColors.setNewThemeColor(MainActivity.this, red, green, blue);
}
}
To change color, just replace Random with your RGB, Hope this helps.
There is a complete example: ColorTest.zip
Setting the -fx-text-fill
works for me.
See below:
if (passed) {
resultInfo.setText("Passed!");
resultInfo.setStyle("-fx-text-fill: green; -fx-font-size: 16px;");
} else {
resultInfo.setText("Failed!");
resultInfo.setStyle("-fx-text-fill: red; -fx-font-size: 16px;");
}
You should use 'zip' function. Here is an example how your own zip function can look like
def custom_zip(seq1, seq2):
it1 = iter(seq1)
it2 = iter(seq2)
while True:
yield next(it1), next(it2)
You can use CSS to do it for example
<style>
html{
width:100%;
height:100%;
}
body{
width:100%;
height:100%;
background-color:#DDD;
}
</style>
I would suggest using a different approach. Add a button on the webpage that will copy the content of the table to the clipboard, with TAB chars between columns and newlines between rows. This way the "paste" function in Excel should work correctly and your web application will also work with many browsers and on many operating systems (linux, mac, mobile) and users will be able to use the data also with other spreadsheets or word processing programs.
The only tricky part is to copy to the clipboard because many browsers are security obsessed on this. A solution is to prepare the data already selected in a textarea, and show it to the user in a modal dialog box where you tell the user to copy the text (some will need to type Ctrl-C, others Command-c, others will use a "long touch" or a popup menu).
It would be nicer to have a standard copy-to-clipboard function that possibly requests a user confirmation... but this is not the case, unfortunately.
Since 9.6 this is a lot easier as it introduced the function pg_blocking_pids()
to find the sessions that are blocking another session.
So you can use something like this:
select pid,
usename,
pg_blocking_pids(pid) as blocked_by,
query as blocked_query
from pg_stat_activity
where cardinality(pg_blocking_pids(pid)) > 0;
What do you want to fade? The background
or color
attribute?
Currently you're changing the background color, but telling it to transition the color property. You can use all
to transition all properties.
.clicker {
-moz-transition: all .2s ease-in;
-o-transition: all .2s ease-in;
-webkit-transition: all .2s ease-in;
transition: all .2s ease-in;
background: #f5f5f5;
padding: 20px;
}
.clicker:hover {
background: #eee;
}
Otherwise just use transition: background .2s ease-in
.
You should be able to find your command with a ps
variant like:
ps -ef
ps -fubob # if your job's user ID is bob.
Then, once located, it should be a simple matter to use kill
to kill the process (permissions permitting).
If you're talking about getting rid of jobs in the at
queue (that aren't running yet), you can use atq
to list them and atrm
to get rid of them.
Best solution you have ever see.

update:
double angle = 20.3034;
DecimalFormat df = new DecimalFormat("#.00");
String angleFormated = df.format(angle);
System.out.println(angleFormated); //output 20.30
Your code wasn't using the decimalformat correctly
The 0 in the pattern means an obligatory digit, the # means optional digit.
update 2: check bellow answer
If you want 0.2677
formatted as 0.27
you should use new DecimalFormat("0.00");
otherwise it will be .27
On a Mac you can can select the text that you are after then press: cmd + ctrl + G
This will select every instance of your selected text within the same document. If you now start typing to replace your original highlighted text, you will replace all of the other occurrences at the same time.
Try to make pairs of numbers from the set. The first + the last; the second + the one before last. It means n-1 + 1; n-2 + 2. The result is always n. And since you are adding two numbers together, there are only (n-1)/2 pairs that can be made from (n-1) numbers.
So it is like (N-1)/2 * N.
This works both with headless

from selenium.webdriver import Firefox, FirefoxOptions

I use for(;/*ever*/;)
.
It is easy to read and it takes a bit longer to type (due to the shifts for the asterisks), indicating I should be really careful when using this type of loop. The green text that shows up in the conditional is also a pretty odd sight—another indication this construct is frowned upon unless absolutely necessary.
Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?
you can use $(this).offset()

I create a library RMMapper (https://github.com/roomorama/RMMapper) to help save custom object into NSUserDefaults easier and more convenient, because implementing encodeWithCoder and initWithCoder is super boring!
To mark a class as archivable, just use: #import "NSObject+RMArchivable.h"
To save a custom object into NSUserDefaults:
#import "NSUserDefaults+RMSaveCustomObject.h"
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
[defaults rm_setCustomObject:user forKey:@"SAVED_DATA"];
To get custom obj from NSUserDefaults:
user = [defaults rm_customObjectForKey:@"SAVED_DATA"];
Just make sure that the controller name is the same as yours DeliveryController if you renamed it (it will not change automatically!). if you rename the project name too you should delete the reference to this project from the Bin folder. Don't forget to specify the method get or post.
If the object is actually a Boolean
instance, then just cast it:
boolean di = (Boolean) someObject;
The explicit cast will do the conversion to Boolean
, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:
boolean di = ((Boolean) someObject).booleanValue();
If someObject
doesn't refer to a Boolean value though, what do you want the code to do?

>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)
Must it be an Eclipse plug-in? I use doxygen, just supply your code folder, it handles the rest.

You need slightly different error handling for powershell functions and for calling exe's, and you need to be sure to tell the caller of your script that it has failed. Building on top of Exec
from the library Psake, a script that has the structure below will stop on all errors, and is usable as a base template for most scripts.
Set-StrictMode -Version latest
$ErrorActionPreference = "Stop"
# Taken from psake https://github.com/psake/psake
<#
.SYNOPSIS
This is a helper function that runs a scriptblock and checks the PS variable $lastexitcode
to see if an error occcured. If an error is detected then an exception is thrown.
This function allows you to run command-line programs without having to
explicitly check the $lastexitcode variable.
.EXAMPLE
exec { svn info $repository_trunk } "Error executing SVN. Please verify SVN command-line client is installed"
#>
function Exec
{
[CmdletBinding()]
param(
[Parameter(Position=0,Mandatory=1)][scriptblock]$cmd,
[Parameter(Position=1,Mandatory=0)][string]$errorMessage = ("Error executing command {0}" -f $cmd)
)
& $cmd
if ($lastexitcode -ne 0) {
throw ("Exec: " + $errorMessage)
}
}
Try {
# Put all your stuff inside here!
# powershell functions called as normal and try..catch reports errors
New-Object System.Net.WebClient
# call exe's and check their exit code using Exec
Exec { setup.exe }
} Catch {
# tell the caller it has all gone wrong
$host.SetShouldExit(-1)
throw
}
The instanceof
operator does not need explicit null
checks, as it does not throw a NullPointerException
if the operand is null
.
At run time, the result of the instanceof
operator is true if the value of the relational expression is not null
and the reference could be cast to the reference type without raising a class cast exception.
If the operand is null
, the instanceof
operator returns false
and hence, explicit null checks are not required.
Consider the below example,
public static void main(String[] args) {
if(lista != null && lista instanceof ArrayList) { //Violation
System.out.println("In if block");
}
else {
System.out.println("In else block");
}
}
The correct usage of instanceof
is as shown below,
public static void main(String[] args) {
if(lista instanceof ArrayList){ //Correct way
System.out.println("In if block");
}
else {
System.out.println("In else block");
}
}
It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.
All answers are great, but they are talking about adding extension method to a specific type of enum.
What if you want to add a method to all enums like returning an int of current value instead of explicit casting?
public static class EnumExtensions
{
public static int ToInt<T>(this T soure) where T : IConvertible//enum
{
if (!typeof(T).IsEnum)
throw new ArgumentException("T must be an enumerated type");
return (int) (IConvertible) soure;
}
//ShawnFeatherly funtion (above answer) but as extention method
public static int Count<T>(this T soure) where T : IConvertible//enum
{
if (!typeof(T).IsEnum)
throw new ArgumentException("T must be an enumerated type");
return Enum.GetNames(typeof(T)).Length;
}
}
The trick behind IConvertible
is its Inheritance Hierarchy see MDSN
Thanks to ShawnFeatherly for his answer
Try autoplay="autoplay"
instead of the "true"
value. That's the documented way to enable autoplay. That sounds weirdly redundant, I know.
It should put java in your path, probably in /usr/bin/java. The easiest way to find it is to open a term and type "which java".
Twine is an open-source tool for telling interactive, nonlinear stories. It generates a single html with multiples pages. Maybe it is not the right tool for you but it could be useful for someone else looking for something similar.
I use fetchObject() here a small example using Symfony 4.4
<?php
use Doctrine\DBAL\Driver\Connection;
class MyController{
public function index($username){
$queryBuilder = $connection->createQueryBuilder();
$queryBuilder
->select('id', 'name')
->from('app_user')
->where('name = ?')
->setParameter(0, $username)
->setMaxResults(1);
$stmUser = $queryBuilder->execute();
dump($stmUser->fetchObject());
//get_class_methods($stmUser) -> to see all methods
}
}
Response:
{
"id": "2", "name":"myuser"
}
This error
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown.
occurs when creating a docker image from base image eg. scratch
. This is because the resulting image does not have a shell to execute the image. If your use:
ENV EXECUTABLE hello
cmd [$EXECUTABLE]
in your docker file, docker uses /bin/sh to parse the input string. and hence the error. Inspecting on the image, your will find:
$docker inspect <image-name>
"Entrypoint": [
"/bin/sh",
"-c",
"[$HM_APP]"
]
This means that the ENTRYPOINT or CMD arguments will be parsed using /bin/sh -c. The solution that worked for me is to parse the command as a JSON array of string e.g.
cmd ["hello"]
and inspecting the image again:
"Entrypoint": [
"hello"
]
This removes the dependence on /bin/sh the docker app can now execute the binary file. Example:
FROM scratch
# Environmental variables
# Copy files
ADD . /
# Home dir
WORKDIR /bin
EXPOSE 8083
ENTRYPOINT ["hospitalms"]
Hope this helps someone in future.

Found this snippet on http://www.java2s.com/Code/VBA-Excel-Access-Word/Excel/Checksvaluesinarange10rowsby5columns.htm It seems to be quite useful as a function to illustrate the means to check values in cells in an ordered fashion.
Just imagine it as being a 2d Array of sorts and apply the same logic to loop through cells.
E-mail addresses are very difficult to verify correctly with a mere regex. Here is a pretty scary regex that supposedly implements RFC822, chapter 6, the specification of valid e-mail addresses.
Not really an answer, but maybe related to what you're trying to accomplish.
Using .multiply() (ufunc multiply)
a_1 = np.array([1.0, 2.0, 3.0])
a_2 = np.array([[1., 2.], [3., 4.]])
b = 2.0
np.multiply(a_1,b)
# array([2., 4., 6.])
np.multiply(a_2,b)
# array([[2., 4.],[6., 8.]])
I was looking for a good option for IE10 and below CSS styling (but it would work for IE8 only as well) and I came up with this idea:
<!--[if lt IE 10]><div class="column IE10-fix"><![endif]-->
<!--[if !lt IE 10]><!--><div class="column"><!--<![endif]-->
I declare my div or whatever you want with an extra class, this allows me to have extra CSS in the same stylesheet in a very readable manner.
It's W3C valid and not a weird CSS hack.
The urls are different.
http://localhost/AccountSvc/DataInquiry.asmx
vs.
/acctinqsvc/portfolioinquiry.asmx
Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.
You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx
, and specify the desired method/operation in the SOAPAction header.
The SOAPAction header values are different.
http://localhost/AccountSvc/DataInquiry.asmx/ + methodName
vs.
http://tempuri.org/GetMyName
You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl
There should be a <soap:operation>
tag underneath the <wsdl:operation>
tag that matches the operation you are attempting to execute, which appears to be GetMyName
.
There is no XML declaration in the request body that includes your SOAP XML.
You specify text/xml
in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii
, but there's no telling if you aren't specifying them!
The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8
Hope that helps!
DBCC SHRINKDATABASE
works for me, but this is its full syntax:
DBCC SHRINKDATABASE ( database_name, [target_percent], [truncate] )
where target_percent
is the desired percentage of free space left in the database file after the database has been shrunk.
And truncate
parameter can be:
NOTRUNCATE
Causes the freed file space to be retained in the database files. If not specified, the freed file space is released to the operating system.
TRUNCATEONLY
Causes any unused space in the data files to be released to the operating system and shrinks the file to the last allocated extent, reducing the file size without moving any data. No attempt is made to relocate rows to unallocated pages. target_percent is ignored when TRUNCATEONLY is used.
...and yes no_one is right, shrinking datbase is not very good practice becasue for example :
shrink on data files are excellent ways to introduce significant logical fragmentation, becasue it moves pages from the end of the allocated range of a database file to somewhere at the front of the file...
shrink database can have a lot of consequence on database, server.... think a lot about it before you do it!
on the web there are a lot of blogs and articles about it.
This is the closer I could get to the one liner this should be if the Android API was any smart:
new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();
Internally, .bind
maps directly to .on
in the current version of jQuery. (The same goes for .live
.) So there is a tiny but practically insignificant performance hit if you use .bind
instead.
However, .bind
may be removed from future versions at any time. There is no reason to keep using .bind
and every reason to prefer .on
instead.
The solution without div
is used a pseudo element like ::after
into first td
in row with min-height
. Save your HTML clean.
table tr td:first-child::after {
content: "";
display: inline-block;
vertical-align: top;
min-height: 60px;
}
On most (see details below) browsers, editing the placeholder in javascript allows multiline placeholder. As it has been said, it's not compliant with the specification and you shouldn't expect it to work in the future (edit: it does work).
This example replaces all multiline textarea's placeholder.
var textAreas = document.getElementsByTagName('textarea');
Array.prototype.forEach.call(textAreas, function(elem) {
elem.placeholder = elem.placeholder.replace(/\\n/g, '\n');
});

placeholder="Hello, \nThis is multiline example \n\nHave Fun"
rows="5" cols="35"></textarea>

JsFiddle snippet.
Expected resultBased on comments it seems some browser accepts this hack and others don't.
This is the results of tests I ran (with browsertshots and browserstack)
Fused with theses statistics, this means that it works on about 88.7% of currently (Oct 2015) used browsers.
Update: Today, it works on at least 94.4% of currently (July 2018) used browsers.
I don't know about javax.media.j3d, so I might be mistaken, but you usually want to investigate whether there is a memory leak. Well, as others note, if it was 64MB and you are doing something with 3d, maybe it's obviously too small...
But if I were you, I'll set up a profiler or visualvm, and let your application run for extended time (days, weeks...). Then look at the heap allocation history, and make sure it's not a memory leak.
If you use a profiler, like JProfiler or the one that comes with NetBeans IDE etc., you can see what object is being accumulating, and then track down what's going on.. Well, almost always something is incorrectly not removed from a collection...
Just setting the return value to the function name is still not exactly the same as the Java (or other) return
statement, because in java, return
exits the function, like this:
public int test(int x) {
if (x == 1) {
return 1; // exits immediately
}
// still here? return 0 as default.
return 0;
}
In VB, the exact equivalent takes two lines if you are not setting the return value at the end of your function. So, in VB the exact corollary would look like this:
Public Function test(ByVal x As Integer) As Integer
If x = 1 Then
test = 1 ' does not exit immediately. You must manually terminate...
Exit Function ' to exit
End If
' Still here? return 0 as default.
test = 0
' no need for an Exit Function because we're about to exit anyway.
End Function
Since this is the case, it's also nice to know that you can use the return variable like any other variable in the method. Like this:
Public Function test(ByVal x As Integer) As Integer
test = x ' <-- set the return value
If test <> 1 Then ' Test the currently set return value
test = 0 ' Reset the return value to a *new* value
End If
End Function
Or, the extreme example of how the return variable works (but not necessarily a good example of how you should actually code)—the one that will keep you up at night:
Public Function test(ByVal x As Integer) As Integer
test = x ' <-- set the return value
If test > 0 Then
' RECURSIVE CALL...WITH THE RETURN VALUE AS AN ARGUMENT,
' AND THE RESULT RESETTING THE RETURN VALUE.
test = test(test - 1)
End If
End Function
Solution that worked for me for Excel Interop:
myWorksheet.Columns[j].NumberFormat = "@"; // column as a text
myWorksheet.Cells[i + 2, j].NumberFormat = "@"; // cell as a text
This code should run before putting data to Excel. Column and row numbers are 1-based.
A bit more details. Whereas accepted response with reference for SpreadsheetGear looks almost correct, I had two concerns about it:
Cprcrack's answer works very well for API levels 19 and under. Just a minor addition to cprcrack's onShowCustomView
will get it working on API level 21+
if (Build.VERSION.SDK_INT >= 21) {
videoViewContainer.setBackgroundColor(Color.BLACK);
((ViewGroup) webView.getParent()).addView(videoViewContainer);
webView.scrollTo(0,0); // centers full screen view
} else {
activityNonVideoView.setVisibility(View.INVISIBLE);
ViewGroup.LayoutParams vg = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
activityVideoView.addView(videoViewContainer,vg);
activityVideoView.setVisibility(View.VISIBLE);
}
You will also need to reflect the changes in onHideCustomView
For me general solution :)

I like to do this witch i think is cleaner :
1 - Add the model to namespace:
use App\Employee;
2 - then you can do :
$employees = Employee::get();
or maybe somthing like this:
$employee = Employee::where('name', 'John')->first();
You just need to add a /A
behind the line.
Example:
get-childitem C:\temp\ -exclude *.svn-base,".svn" -recurse | foreach ($_) {remove-item $_.fullname} /a
