Same issue. In my case I solved setting the project as the "StartUp Project".
Look at this awesome new library which is available via gradle :)
build.gradle: compile 'com.apptakk.http_request:http-request:0.1.2'
Usage:
new HttpRequestTask(
new HttpRequest("http://httpbin.org/post", HttpRequest.POST, "{ \"some\": \"data\" }"),
new HttpRequest.Handler() {
@Override
public void response(HttpResponse response) {
if (response.code == 200) {
Log.d(this.getClass().toString(), "Request successful!");
} else {
Log.e(this.getClass().toString(), "Request unsuccessful: " + response);
}
}
}).execute();
This was inspired by using Sets as indexers in Delphi, way back when:
/// Example of using a Boolean indexed property
/// to manipulate a [Flags] enum:
public class BindingFlagsIndexer
{
BindingFlags flags = BindingFlags.Default;
public BindingFlagsIndexer()
{
}
public BindingFlagsIndexer( BindingFlags value )
{
this.flags = value;
}
public bool this[BindingFlags index]
{
get
{
return (this.flags & index) == index;
}
set( bool value )
{
if( value )
this.flags |= index;
else
this.flags &= ~index;
}
}
public BindingFlags Value
{
get
{
return flags;
}
set( BindingFlags value )
{
this.flags = value;
}
}
public static implicit operator BindingFlags( BindingFlagsIndexer src )
{
return src != null ? src.Value : BindingFlags.Default;
}
public static implicit operator BindingFlagsIndexer( BindingFlags src )
{
return new BindingFlagsIndexer( src );
}
}
public static class Class1
{
public static void Example()
{
BindingFlagsIndexer myFlags = new BindingFlagsIndexer();
// Sets the flag(s) passed as the indexer:
myFlags[BindingFlags.ExactBinding] = true;
// Indexer can specify multiple flags at once:
myFlags[BindingFlags.Instance | BindingFlags.Static] = true;
// Get boolean indicating if specified flag(s) are set:
bool flatten = myFlags[BindingFlags.FlattenHierarchy];
// use | to test if multiple flags are set:
bool isProtected = ! myFlags[BindingFlags.Public | BindingFlags.NonPublic];
}
}
I find answer. Thanks all but right answer next:
$("#myModal").on("hidden", function () {
$('#result').html('yes,result');
});
Events here http://bootstrap-ru.com/javascript.php#modals
UPD
For Bootstrap 3.x need use hidden.bs.modal:
$("#myModal").on("hidden.bs.modal", function () {
$('#result').html('yes,result');
});

I dont think you need any complicated script for this. Just use

Simple functionality is not included in Swift, expected because it's included in other languages, can often be quickly coded for reuse. Pro tip for programmers to create a bag of tricks file that contains all this reuse code.
So from my bag of tricks we first need string multiplication for use in indentation.
@inlinable func * (string: String, scalar: Int) -> String {
let array = [String](repeating: string, count: scalar)
return array.joined(separator: "")
}
and then the code to add commas.
extension Int {
@inlinable var withCommas:String {
var i = self
var retValue:[String] = []
while i >= 1000 {
retValue.append(String(format:"%03d",i%1000))
i /= 1000
}
retValue.append("\(i)")
return retValue.reversed().joined(separator: ",")
}
@inlinable func withCommas(_ count:Int = 0) -> String {
let retValue = self.withCommas
let indentation = count - retValue.count
let indent:String = indentation >= 0 ? " " * indentation : ""
return indent + retValue
}
}
I just wrote this last function so I could get the columns to line up.
The @inlinable is great because it takes small functions and reduces their functionality so they run faster.
You can use either the variable version or, to get a fixed column, use the function version. Lengths set less than the needed columns will just expand the field.
Now you have something that is pure Swift and does not rely on some old objective C routine for NSString.

You can reset your branch to the state it was in just before the merge if you find the commit it was on then.
One way is to use git reflog
, it will list all the HEADs you've had.
I find that git reflog --relative-date
is very useful as it shows how long ago each change happened.
Once you find that commit just do a git reset --hard <commit id>
and your branch will be as it was before.
If you have SourceTree, you can look up the <commit id>
there if git reflog
is too overwhelming.
You can loop the array with a for loop and the object properties with for-in loops.
for (var i=0; i<result.length; i++)
for (var name in result[i]) {
console.log("Item name: "+name);
console.log("Source: "+result[i][name].sourceUuid);
console.log("Target: "+result[i][name].targetUuid);
}

Visual Studio 2015 Update 3 does not support the C++17 feature you are looking for (emplace_back()
returning a reference).

I get consistent behaviour for both instances:
>>> ls[0:10]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> ls[10:-1]
[10, 11, 12, 13, 14, 15, 16, 17, 18]
Note, though, that tenth element of the list is at index 9, since the list is 0-indexed. That might be where your hang-up is.
In other words, [0:10]
doesn't go from index 0-10, it effectively goes from 0 to the tenth element (which gets you indexes 0-9, since the 10 is not inclusive at the end of the slice).
It appears from your question that you already have a second set of DNS servers available that reference the development site instead of the live site.
I would suggest that you simply run a standard SOCKS proxy either on that DNS server system or on a low-end spare system and have that system configured to use the development DNS server. You can then tell Firefox to use that proxy instead of downloading pages directly.
Doing it this way, the actual DNS lookups will be done on the proxy machine and not on the machine that's running the web browser.

BLOB A string with a maximum length of 65535 characters.
The MySQL manual says:
The maximum size of a BLOB or TEXT object is determined by its type, but the largest value you actually can transmit between the client and server is determined by the amount of available memory and the size of the communications buffers
I think the first site gets their answers from interpreting the MySQL manual, per http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html

CheckBoxFor
takes a bool
, you're passing a List<CheckBoxes>
to it. You'd need to do:
@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
@Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
@Html.HiddenFor(m => m.EmploymentType[i].Text)
@Html.DisplayFor(m => m.EmploymentType[i].Text)
}
Notice I've added a HiddenFor
for the Text
property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.
Edit, as shown in your comments, your EmploymentType
list is null
when the view is served. You'll need to populate that too, by doing this in your action method:
public ActionResult YourActionMethod()
{
CareerForm model = new CareerForm();
model.EmploymentType = new List<CheckBox>
{
new CheckBox { Text = "Fulltime" },
new CheckBox { Text = "Partly" },
new CheckBox { Text = "Contract" }
};
return View(model);
}

If you want to do it on your own, you're going to be in for a good amount of work. Check out the isNaN()
function. It tells you if it is not a number. You're also going to want to brush up on your regular expressions for validation. If you're using RegEx, you can go without isNaN()
, as you'll be testing for that anyway.

When you parse the JSON representation, it'll become a JavaScript array of objects.
Because of this, you can use the .length
property of the JavaScript array to see how many elements are contained, and use a for
loop to enumerate it.
Consider using System.Windows.Forms.Timer
instead of System.Threading.Timer
for a GUI application, for timers that are based on the Windows message queue instead of on dedicated threads or the thread pool.
In your scenario, for the purpose of periodic updates of UI, it seems particularly appropriate since you don't really have a background work or long calculation to perform. You just want to do periodic small tasks that have to happen on the UI thread anyway.
IANA has registered the official MIME Type for JSON as application/json
.
When asked about why not text/json
, Crockford seems to have said JSON is not really JavaScript nor text and also IANA was more likely to hand out application/*
than text/*
.
More resources:
ExecutorService is newer and more general. A timer is just a thread that periodically runs stuff you have scheduled for it.
An ExecutorService may be a thread pool, or even spread out across other systems in a cluster and do things like one-off batch execution, etc...
Just look at what each offers to decide.
For string operations use StringBuilder or StringBuffer classes for accumulating string data blocks. Do not use +=
operations for string objects. String
class is immutable and you will produce a large amount of string objects upon runtime and it will affect on performance.
Use .append()
method of StringBuilder/StringBuffer class instance instead.
Try below:
import pyodbc
server = 'servername'
database = 'DB'
username = 'UserName'
password = 'Password'
cnxn = pyodbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
cursor.execute('SELECT * FROM Tbl')
for row in cursor:
print('row = %r' % (row,))
You can also try use "doctor" command. It will fix most cases.
npx @react-native-community/cli doctor
Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.
Which leads to the error mentioned in comments above:
Uncaught TypeError: Property 'submit' of object
#<HTMLFormElement>
is not a function
As in the accepted answer above the simplest solution would be to change the name of that control element.
However another solution could be to use dispatchEvent
method on form element:
$("#form_id")[0].dispatchEvent(new Event('submit'));
First thing, define a type or interface for your object, it will make things much more readable:
type Product = { productId: number; price: number; discount: number };
You used a tuple of size one instead of array, it should look like this:
let myarray: Product[];
let priceListMap : Map<number, Product[]> = new Map<number, Product[]>();
So now this works fine:
myarray.push({productId : 1 , price : 100 , discount : 10});
myarray.push({productId : 2 , price : 200 , discount : 20});
myarray.push({productId : 3 , price : 300 , discount : 30});
priceListMap.set(1 , this.myarray);
myarray = null;
I'm aware there are a lot of answers, but I thought I might just provide my implementation of it as well. (Full details can be found on another question I answered).
So, to add a click listener, your inner ViewHolder
class needs to implement View.OnClickListener
. This is because you will set an OnClickListener
to the itemView
parameter of the ViewHolder
's constructor. Let me show you what I mean:
public class ExampleClickViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView text1, text2;
ExampleClickViewHolder(View itemView) {
super(itemView);
// we do this because we want to check when an item has been clicked:
itemView.setOnClickListener(this);
// now, like before, we assign our View variables
title = (TextView) itemView.findViewById(R.id.text1);
subtitle = (TextView) itemView.findViewById(R.id.text2);
}
@Override
public void onClick(View v) {
// The user may not set a click listener for list items, in which case our listener
// will be null, so we need to check for this
if (mOnEntryClickListener != null) {
mOnEntryClickListener.onEntryClick(v, getLayoutPosition());
}
}
}
The only other things you need to add are a custom interface for your Adapter
and a setter method:
private OnEntryClickListener mOnEntryClickListener;
public interface OnEntryClickListener {
void onEntryClick(View view, int position);
}
public void setOnEntryClickListener(OnEntryClickListener onEntryClickListener) {
mOnEntryClickListener = onEntryClickListener;
}
So your new, click-supporting Adapter
is complete.
Now, let's use it...
ExampleClickAdapter clickAdapter = new ExampleClickAdapter(yourObjects);
clickAdapter.setOnEntryClickListener(new ExampleClickAdapter.OnEntryClickListener() {
@Override
public void onEntryClick(View view, int position) {
// stuff that will happen when a list item is clicked
}
});
It's basically how you would set up a normal Adapter
, except that you use your setter method that you created to control what you will do when your user clicks a particular list item.
You can also look through a set of examples I made on this Gist on GitHub:
https://gist.github.com/FarbodSalamat-Zadeh/7646564f48ee708c1582c013e1de4f07
Panel
has an AutoScroll
property. Just set that property to True
and the panel will automatically add a scroll bar when needed.
You're trying to concatenate a string and an integer, which is incorrect.
Change print(numlist.pop(2)+" has been removed")
to any of these:
Explicit int
to str
conversion:
print(str(numlist.pop(2)) + " has been removed")
Use ,
instead of +
:
print(numlist.pop(2), "has been removed")
String formatting:
print("{} has been removed".format(numlist.pop(2)))
I think this is the simplest alias, add to your ~/.gitconfig
[alias]
publish-branch = !git push -u origin $(git rev-parse --abbrev-ref HEAD)
You just run
git publish-branch
and... it publishes the branch
Not the most elegant, but I do (for Python 3):
if hasattr(instance, '__iter__') and not isinstance(instance, (str, bytes)):
...
This allows other iterables (like Django querysets) but excludes strings and bytestrings. I typically use this in functions that accept either a single object ID or a list of object IDs. Sometimes the object IDs can be strings and I don't want to iterate over those character by character. :)
You can't set a number in an arbitrary place in the array without telling the array how big it needs to be. For your example: int[] array = new int[4];
I was having this same problem, and tried all the above solutions with no success. I finally solved the problem by deleting the entire query and creating a new one.
The new one had the exact same settings as the one that didn't work (literally the same query definition as I simply copied the old one).
I have no idea why this solved the problem, but it did.
Just add your modulus (arrayLength) to the negative result of % and you'll be fine.
You have to cast the selected item to your custom class (ComboboxItem) Try this:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ComboBox cmb = (ComboBox)sender;
int selectedIndex = cmb.SelectedIndex;
string selectedText = this.comboBox1.Text;
string selectedValue = ((ComboboxItem)cmb.SelectedItem).Value.ToString();
ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));
}
Well one way to do it would be to just put a class on the "parent" rows and remove all the ids and inline onclick
attributes:
<table id="products">
<thead>
<tr>
<th>Product</th>
<th>Price</th>
<th>Destination</th>
<th>Updated on</th>
</tr>
</thead>
<tbody>
<tr class="parent">
<td>Oranges</td>
<td>100</td>
<td><a href="#">+ On Store</a></td>
<td>22/10</td>
</tr>
<tr>
<td></td>
<td>120</td>
<td>City 1</td>
<td>22/10</td>
</tr>
<tr>
<td></td>
<td>140</td>
<td>City 2</td>
<td>22/10</td>
</tr>
...etc.
</tbody>
</table>
And then have some CSS that hides all non-parents:
tbody tr {
display : none; // default is hidden
}
tr.parent {
display : table-row; // parents are shown
}
tr.open {
display : table-row; // class to be given to "open" child rows
}
That greatly simplifies your html. Note that I've added <thead>
and <tbody>
to your markup to make it easy to hide data rows and ignore heading rows.
With jQuery you can then simply do this:
// when an anchor in the table is clicked
$("#products").on("click","a",function(e) {
// prevent default behaviour
e.preventDefault();
// find all the following TR elements up to the next "parent"
// and toggle their "open" class
$(this).closest("tr").nextUntil(".parent").toggleClass("open");
});
Demo: http://jsfiddle.net/CBLWS/1/
Or, to implement something like that in plain JavaScript, perhaps something like the following:
document.getElementById("products").addEventListener("click", function(e) {
// if clicked item is an anchor
if (e.target.tagName === "A") {
e.preventDefault();
// get reference to anchor's parent TR
var row = e.target.parentNode.parentNode;
// loop through all of the following TRs until the next parent is found
while ((row = nextTr(row)) && !/\bparent\b/.test(row.className))
toggle_it(row);
}
});
function nextTr(row) {
// find next sibling that is an element (skip text nodes, etc.)
while ((row = row.nextSibling) && row.nodeType != 1);
return row;
}
function toggle_it(item){
if (/\bopen\b/.test(item.className)) // if item already has the class
item.className = item.className.replace(/\bopen\b/," "); // remove it
else // otherwise
item.className += " open"; // add it
}
Demo: http://jsfiddle.net/CBLWS/
Either way, put the JavaScript in a <script>
element that is at the end of the body, so that it runs after the table has been parsed.
Paolo's general idea (i.e. effectively changing some part of the request uri) is your best bet. However, I'd suggest using a more static value such as a version number that you update when you have changed your script file so that you can still get the performance gains of caching.
So either something like this:
<script src="/my/js/file.js?version=2.1.3" ></script>
or maybe
<script src="/my/js/file.2.1.3.js" ></script>
I prefer the first option because it means you can maintain the one file instead of having to constantly rename it (which for example maintains consistent version history in your source control). Of course either one (as I've described them) would involve updating your include statements each time, so you may want to come up with a dynamic way of doing it, such as replacing a fixed value with a dynamic one every time you deploy (using Ant or whatever).
Intellisense did not recognized an imported namespace in my case, although I could compile the project successfully. The solution was to uncheck imported namespace on project references tab, save the project, check it again and save the project again.
Maybe not the most efficient way. But you could convert the list into a vector.
#include <list>
#include <vector>
list<Object> myList;
vector<Object> myVector(myList.begin(), myList.end());
Then access the vector using the [x] operator.
auto x = MyVector[0];
You could put that in a helper function:
#include <memory>
#include <vector>
#include <list>
template<class T>
shared_ptr<vector<T>>
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
new vector<string>(List.begin(), List.end()) }
return Vector;
}
Then use the helper funciton like this:
auto MyVector = ListToVector(Object);
auto x = MyVector[0];
Apart from the options already given in other answers, there's a current more active, recent and open-source project called pygubu
.
This is the first description by the author taken from the github repository:
Pygubu is a RAD tool to enable quick & easy development of user interfaces for the python tkinter module.
The user interfaces designed are saved as XML, and by using the pygubu builder these can be loaded by applications dynamically as needed. Pygubu is inspired by Glade.
Pygubu hello world program is an introductory video explaining how to create a first project using Pygubu
.
The following in an image of interface of the last version of pygubu
designer on a OS X Yosemite 10.10.2:
I would definitely give it a try, and contribute to its development.
The answer from Daniel works just perfect. Here is a sample snippet that I added to my build.xml:
<target name="compile">
<mkdir dir="${classes.dir}"/>
<javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false">
<!-- ^^^^^^^^^^^^^^^^^^^^^^^^^ -->
<classpath>
<path id="application" location="${jar.dir}/${ant.project.name}.jar"/>
<path id="junit" location="${lib.dir}/junit-4.9b2.jar"/>
</classpath>
</javac>
</target>
For me I was getting the problem when deploying a geoserver WAR
into tomcat 7
To fix it, I was on Java 7 and upgrading to Java 8.
This is running under a docker container. Tomcat 7.0.75

+ Geos 2.10.2
Using jQuery:
$('#Button').click(function(){
$(this).addClass("active");
});
This way, you don't have to pollute your HTML markup with onclick
handlers.
As of iOS 9.0 there's no way to get the orientation reliably. This is the code I used for an app I design for only portrait mode, so if the app is opened in landscape mode it will still be accurate:
screenHeight = [[UIScreen mainScreen] bounds].size.height;
screenWidth = [[UIScreen mainScreen] bounds].size.width;
if (screenWidth > screenHeight) {
float tempHeight = screenWidth;
screenWidth = screenHeight;
screenHeight = tempHeight;
}
you have to set cellpadding and cellspacing that's it.
<table cellpadding="5" cellspacing="5">
<tr>
<td>One</td>
<td>Two</td>
<td>Three</td>
<td>Four</td>
</tr>
</table>

Use formpost to post your data to action
var inputTag = '<input name="paramName" type="text" value="' + payloadString + '">';
var form = document.createElement("form");
jQuery(form).attr("id", "pdf-form").attr("name", "pdf-form").attr("class", "pdf-form").attr("target", "_blank");
jQuery(form).attr("action", "/Controller/OpenPDF").attr("method", "post").attr("enctype", "multipart/form-data");
jQuery(form).append(inputTag);
document.body.appendChild(form);
form.submit();
document.body.removeChild(form);
return false;
You need to create a form to post your data, append it your dom, post your data and remove the form your document body.
However, form post wouldn't post data to new tab only on EDGE browser. But a get request works as it's just opening new tab with a url containing query string for your action parameters.
It is possible
You just also need to apply the color to 'tbody' element as that's the table body that's been causing our trouble by peeking underneath.table, tbody, tr, th, td{
background-color: rgba(0, 0, 0, 0.0) !important;
}
ALTER TABLE `tbl_celebrity_rows` ADD CONSTRAINT `tbl_celebrity_rows_ibfk_1` FOREIGN KEY (`celebrity_id`)
REFERENCES `tbl_celebrities`(`id`) ON DELETE CASCADE ON UPDATE RESTRICT;
As per François Noël's answer "For those who still can't make this work, make sure that the overflowed element is displayed before using the jQuery function."
I had been working in a bootstrap modal that I repeatedly bring up with account permissions in a div that overflows on the y dimension. My problem was, I was trying to use the jquery .scrollTop(0) function and it would not work no matter how I tried to do it. I had to setup an event for the modal that didn't reset the scrollbar until the modal had stopped animating. The code that finally worked for me is here:
$('#add-modal').on('shown.bs.modal', function (e) {
$('div.border').scrollTop(0);
});
You can also link your .ssh directory between the host and the container, I don't know if this method has any security implications but it may be the easiest method. Something like this should work:
$ sudo docker run -it -v /root/.ssh:/root/.ssh someimage bash
Remember that docker runs with sudo (unless you don't), if this is the case you'll be using the root ssh keys.
As pointed out in a few other answers, you can iterate over all elements in a matrix A
(of any dimension) using a linear index from 1
to numel(A)
in a single for loop. There are also a couple of functions you can use: arrayfun
and cellfun
.
Let's first assume you have a function that you want to apply to each element of A
(called my_func
). You first create a function handle to this function:
fcn = @my_func;
If A
is a matrix (of type double, single, etc.) of arbitrary dimension, you can use arrayfun
to apply my_func
to each element:
outArgs = arrayfun(fcn, A);
If A
is a cell array of arbitrary dimension, you can use cellfun
to apply my_func
to each cell:
outArgs = cellfun(fcn, A);
The function my_func
has to accept A
as an input. If there are any outputs from my_func
, these are placed in outArgs
, which will be the same size/dimension as A
.
One caveat on outputs... if my_func
returns outputs of different sizes and types when it operates on different elements of A
, then outArgs
will have to be made into a cell array. This is done by calling either arrayfun
or cellfun
with an additional parameter/value pair:
outArgs = arrayfun(fcn, A, 'UniformOutput', false);
outArgs = cellfun(fcn, A, 'UniformOutput', false);
I use the following (stripped-down code) in Firefox 69.0 (on Ubuntu) to read a directory and show the image as part of a digital photo frame. The page is made in HTML, CSS, and JavaScript, and it is located on the same machine where I run the browser. The images are located on the same machine as well, so there is no viewing from "outside".
var directory = <path>;
var xmlHttp = new XMLHttpRequest();
xmlHttp.open('GET', directory, false); // false for synchronous request
xmlHttp.send(null);
var ret = xmlHttp.responseText;
var fileList = ret.split('\n');
for (i = 0; i < fileList.length; i++) {
var fileinfo = fileList[i].split(' ');
if (fileinfo[0] == '201:') {
document.write(fileinfo[1] + "<br>");
document.write('<img src=\"' + directory + fileinfo[1] + '\"/>');
}
}
This requires the policy security.fileuri.strict_origin_policy
to be disabled. This means it might not be a solution you want to use. In my case I deemed it ok.
For those who still have this problem (for example to switch from 2.8.0 to 2.10.0), move to the file gradle-wrapper.properties and set distributionUrl like that.
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
I changed 2.8.0 to 2.10.0 and don't forget to Sync after
There's no need for a regular expression but you do want to use string formatting rather than the string concatenation in the accepted answer.
This is probably the most canonical, Pythonic way to truncate the string data
at 75 characters.
>>> data = "saddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddsaddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddsadddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd"
>>> info = "{}..".format(data[:75]) if len(data) > 75 else data
>>> info
'111111111122222222223333333333444444444455555555556666666666777777777788888...'
This is something I always wanted, especially while setting up test fixtures. Finally, I decided to write a simple fluent builder of my own that could build any Map implementation - https://gist.github.com/samshu/b471f5a2925fa9d9b718795d8bbdfe42#file-mapbuilder-java
/**
* @param mapClass Any {@link Map} implementation type. e.g., HashMap.class
*/
public static <K, V> MapBuilder<K, V> builder(@SuppressWarnings("rawtypes") Class<? extends Map> mapClass)
throws InstantiationException,
IllegalAccessException {
return new MapBuilder<K, V>(mapClass);
}
public MapBuilder<K, V> put(K key, V value) {
map.put(key, value);
return this;
}
public Map<K, V> build() {
return map;
}
Way less code than all other solutions:
Objective-C version:
- (UIViewController *)getTopViewController {
UIViewController *topViewController = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
while (topViewController.presentedViewController) topViewController = topViewController.presentedViewController;
return topViewController;
}
Swift 2.0 version: (credit goes to Steve.B)
func getTopViewController() -> UIViewController {
var topViewController = UIApplication.sharedApplication().delegate!.window!!.rootViewController!
while (topViewController.presentedViewController != nil) {
topViewController = topViewController.presentedViewController!
}
return topViewController
}
Works anywhere in your app, even with modals.
If the IN clause is a parameter (either to SP or hot-built SQL), then this can always be done:
SELECT (SELECT COUNT(1)
FROM product_a
WHERE product_id IN (1, 8, 100)
) = (number of commas in product_id as constant)
If the IN clause is a table, then this can always be done:
SELECT (SELECT COUNT(*)
FROM product_a
WHERE product_id IN (SELECT Products
FROM #WorkTable)
) = (SELECT COUNT(*)
FROM #WorkTable)
If the IN clause is complex then either spool it into a table or write it twice.
Here is how I would do it, its an idea not bulletproof design, you need to modify it

In a Python 2 program that I used for many years there was this line:
ocd[i].namn=unicode(a[:b], 'utf-8')
This did not work in Python 3.
However, the program turned out to work with:
ocd[i].namn=a[:b]
I don't remember why I put unicode there in the first place, but I think it was because the name can contains Swedish letters åäöÅÄÖ. But even they work without "unicode".
Call After would be a better name than the stupid name, callback. When or if condition gets met within a function, call another function, the Call After function, the one received as argument.
Rather than hard-code an inner function within a function, one writes a function to accept an already-written Call After function as argument. The Call After might get called based on state changes detected by code in the function receiving the argument.
If you already use positive and negative button (like I do in my project) you can use Neutral Button to close the dialog.
I also noticed that in Android version >5 the dialog is closed by clicking outside of dialog window but in older version this is not happening.
ad.setNeutralButton("CLOSE", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
// close dialog
}
});
On the latest support library none of the solutions discussed here are necessary anymore. You can play with your Activity
's fragments as you like using the FragmentTransaction
. Just make sure that your fragments can be identified either with an id or tag.
The fragments will be restored automatically as long as you don't try to recreate them on every call to onCreate()
. Instead, you should check if savedInstanceState
is not null and find the old references to the created fragments in this case.
Here is an example:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null) {
myFragment = MyFragment.newInstance();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.my_container, myFragment, MY_FRAGMENT_TAG)
.commit();
} else {
myFragment = (MyFragment) getSupportFragmentManager()
.findFragmentByTag(MY_FRAGMENT_TAG);
}
...
}
Note however that there is currently a bug when restoring the hidden state of a fragment. If you are hiding fragments in your activity, you will need to restore this state manually in this case.
The problem is that if you include fun.cpp in two places in your program, you will end up defining it twice, which isn't valid.
You don't want to include cpp
files. You want to include header files.
The header file should just have the class definition. The corresponding cpp
file, which you will compile separately, will have the function definition.
fun.hpp:
#include <iostream>
class classA {
friend void funct();
public:
classA(int a=1,int b=2):propa(a),propb(b){std::cout<<"constructor\n";}
private:
int propa;
int propb;
void outfun(){
std::cout<<"propa="<<propa<<endl<<"propb="<<propb<< std::endl;
}
};
fun.cpp:
#include "fun.hpp"
using namespace std;
void funct(){
cout<<"enter funct"<<endl;
classA tmp(1,2);
tmp.outfun();
cout<<"exit funct"<<endl;
}
mainfile.cpp:
#include <iostream>
#include "fun.hpp"
using namespace std;
int main(int nargin,char* varargin[]) {
cout<<"call funct"<<endl;
funct();
cout<<"exit main"<<endl;
return 0;
}
Note that it is generally recommended to avoid using namespace std
in header files.
Old question, but still relevant. Here is what worked for me today (6/26/16).
From the bash shell:
lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg
install apt-cyg /bin
Other than the append
function, if by "multiple values" you mean another list, you can simply concatenate them like so.
>>> a = [1,2,3]
>>> b = [4,5,6]
>>> a + b
[1, 2, 3, 4, 5, 6]
I am using Windows and get the same error message. I find another problem which is relevant. I defined OpenCV_DIR in my path at the end of the line. However when I typed "path" in the command line, my OpenCV_DIR was not shown. I found because Windows probably has a limit on how long the path can be, it cut my OpenCV_DIR to be only part of what I defined. So I removed some other part of the path, now it works.
According to my understanding to your question, as an example: you had a style at the beginning in style sheet (ex. background-color: red), then using java script you changed it to another style (ex. background-color: green), now you want to reset the style to its original value in style sheet (background-color: red) without mentioning or even knowing its value (ex. element.style.backgroundColor = 'red')...!
If I'm correct, I have a good solution for you which is using another class name for the element:
steps:
if you want to edit or set a new style, get the element by the new class name and edit the style as desired.
I hope this helps. Regards!
It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:
Access-Control-Allow-Origin:*
or
Access-Control-Allow-Origin:your domain
In Apache config files, the code is like this:
Header set Access-Control-Allow-Origin "*"
In nodejs,the code is like this:
res.setHeader('Access-Control-Allow-Origin','*');
I use Notepad++ and got this error.
In Notepad++ you will see that both the tab and the four spaces are the same, but when you copy your code to Python IDLE you would see the difference and the line with a tab would have more space before it than the others.
To solve the problem, I just deleted the tab before the line then added four spaces.
Using .filter()
also works, and is flexible for id, value, name:
$('input[name="cols"]').filter("[value='Site']").attr('checked', true);
(seen on this blog)
For me it wasn't an angular problem. Was a field of type DateTime in the DB that has a value of (0000-00-00) and my model cannot bind that property correct so I changed to a valid value like (2019-08-12).
I'm using .net core, OData v4 and MySql (EF pomelo connector)
When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.
Since the release of Oracle 12c it is now easier to rearrange columns logically.
Oracle 12c added support for making columns invisible and that feature can be used to rearrange columns logically.
Quote from the documentation on invisible columns:
When you make an invisible column visible, the column is included in the table's column order as the last column.
Create a table:
CREATE TABLE t (
a INT,
b INT,
d INT,
e INT
);
Add a column:
ALTER TABLE t ADD (c INT);
Move the column to the middle:
ALTER TABLE t MODIFY (d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY (d VISIBLE, e VISIBLE);
DESCRIBE t;
Name
----
A
B
C
D
E
I learned about this from an article by Tom Kyte on new features in Oracle 12c.
happens with old node version. use latest version of node like this:
$ nvm use 8.0
$ rm -rf node_modules
$ npm install
$ npm i somemodule
edit: also make sure you save
.
eg: npm install yourmoduleName --save
If using vscodevim extension, ctrl + p won't work so I saw another answer using:
ctrl + shift + p
which opens the command palette. Hit backspace to remove the '>' and then start typing your filename.
This thread says you can't do send private messages to a group of friends on facebook but I found this https://developers.facebook.com/docs/sharing/reference/send-dialog
You could use the below to take multiple inputs separated by a keyword
a,b,c=raw_input("Please enter the age of 3 people in one line using commas\n").split(',')
If you would like to show it in a new window, you could use Tkinter + PIL library, like so:
import tkinter as tk
from PIL import ImageTk, Image
def show_imge(path):
image_window = tk.Tk()
img = ImageTk.PhotoImage(Image.open(path))
panel = tk.Label(image_window, image=img)
panel.pack(side="bottom", fill="both", expand="yes")
image_window.mainloop()
This is a modified example that can be found all over the web.
In case you want to handle intent on opened activity, you can use PendintIntent (Complete steps below):
public class SMSReciver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
try {
if (senderNum.contains("MOB_NUMBER")) {
Toast.makeText(context,"",Toast.LENGTH_SHORT).show();
Intent intentCall = new Intent(context, MainActivity.class);
intentCall.putExtra("message", currentMessage.getMessageBody());
PendingIntent pendingIntent= PendingIntent.getActivity(context, 0, intentCall, PendingIntent.FLAG_UPDATE_CURRENT);
pendingIntent.send();
}
} catch (Exception e) {
}
}
}
} catch (Exception e) {
}
}
}
manifest:
<activity android:name=".MainActivity"
android:launchMode="singleTask"/>
<receiver android:name=".SMSReciver">
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
onNewIntent:
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Toast.makeText(this, "onNewIntent", Toast.LENGTH_SHORT).show();
onSMSReceived(intent.getStringExtra("message"));
}

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />
SELECT *, COUNT(*) FROM my_table
is not what you want, and it's not really valid SQL, you have to group by all the columns that's not an aggregate.
You'd want something like
SELECT somecolumn,someothercolumn, COUNT(*)
FROM my_table
GROUP BY somecolumn,someothercolumn
No trick necessary.
grep --with-filename 'pattern' file
With line numbers:
grep -n --with-filename 'pattern' file
Place this line before the closing script tag,writing from memory:
window.onload = GetTimeZoneOffset;
i think the question is how to call the javascript function on pageload
I would recommend handling the sending of http error codes by using the Boom package.
LocalDate monthstart = LocalDate.of(year,month,1);
LocalDate monthend = monthstart.plusDays(monthstart.lengthOfMonth()-1);
If these strings are currently in the db, you can skip php by using mysql's STR_TO_DATE() function.
I assume the strings use a format like month/day/year
where month
and day
are always 2 digits, and year
is 4 digits.
UPDATE some_table
SET new_column = STR_TO_DATE(old_column, '%m/%d/%Y')
You can support other date formats by using other format specifiers.
A function like that without validating the enum is a trifle dangerous. I suggest using a switch statement. Another advantage is that this can be used for enums that have defined values, for example for flags where the values are 1,2,4,8,16 etc.
Also put all your enum strings together in one array:-
static const char * allEnums[] = {
"Undefined",
"apple",
"orange"
/* etc */
};
define the indices in a header file:-
#define ID_undefined 0
#define ID_fruit_apple 1
#define ID_fruit_orange 2
/* etc */
Doing this makes it easier to produce different versions, for example if you want to make international versions of your program with other languages.
Using a macro, also in the header file:-
#define CASE(type,val) case val: index = ID_##type##_##val; break;
Make a function with a switch statement, this should return a const char *
because the strings static consts:-
const char * FruitString(enum fruit e){
unsigned int index;
switch(e){
CASE(fruit, apple)
CASE(fruit, orange)
CASE(fruit, banana)
/* etc */
default: index = ID_undefined;
}
return allEnums[index];
}
If programming with Windows then the ID_ values can be resource values.
(If using C++ then all the functions can have the same name.
string EnumToString(fruit e);
)
Function for set corner radius programmatically
static void setCornerRadius(GradientDrawable drawable, float topLeft,
float topRight, float bottomRight, float bottomLeft) {
drawable.setCornerRadii(new float[] { topLeft, topLeft, topRight, topRight,
bottomRight, bottomRight, bottomLeft, bottomLeft });
}
static void setCornerRadius(GradientDrawable drawable, float radius) {
drawable.setCornerRadius(radius);
}
Using
GradientDrawable gradientDrawable = new GradientDrawable();
gradientDrawable.setColor(Color.GREEN);
setCornerRadius(gradientDrawable, 20f);
//or setCornerRadius(gradientDrawable, 20f, 40f, 60f, 80f);
view.setBackground(gradientDrawable);
I have learned it is also possible to do this with the exec-maven-plugin if you're doing a "standalone" java app.

I recommend Navicat strongly. What I found particularly excellent are it's import functions - you can import almost any data format (Access, Excel, DBF, Lotus ...), define a mapping between the source and destination which can be saved and is repeatable (I even keep my mappings under version control).
I have tried SQLMaestro and found it buggy (particularly for data import); PGAdmin is limited.
with Apache PDFBox it goes like this:
PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
PDFTextStripper stripper = new PDFTextStripper();
String text = stripper.getText(document);
System.out.println("Text:" + text);
}
document.close();
I agree with several of the points I've read in this post and I've incorporated them into my solution to solve the exact same issue as the original posting.
That said, the comments I appreciated are:
"unless you are using .NET 1.0 or 1.1, use List<T>
instead of ArrayList
. "
"Also, add the item(s) to be deleted to a new list. Then go through and delete those items." .. in my case I just created a new List and the populated it with the valid data values.
e.g.
private List<string> managedLocationIDList = new List<string>();
string managedLocationIDs = ";1321;1235;;" // user input, should be semicolon seperated list of values
managedLocationIDList.AddRange(managedLocationIDs.Split(new char[] { ';' }));
List<string> checkLocationIDs = new List<string>();
// Remove any duplicate ID's and cleanup the string holding the list if ID's
Functions helper = new Functions();
checkLocationIDs = helper.ParseList(managedLocationIDList);
...
public List<string> ParseList(List<string> checkList)
{
List<string> verifiedList = new List<string>();
foreach (string listItem in checkList)
if (!verifiedList.Contains(listItem.Trim()) && listItem != string.Empty)
verifiedList.Add(listItem.Trim());
verifiedList.Sort();
return verifiedList;
}
You can try one simple solution for MySQL:
SELECT DISTINCT city FROM station WHERE city REGEXP "^[aeiou].*[aeiou]$";
Simply use :
mapA.equals(mapB);
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings
I think it is worth mentioning that you don't generally need to use the whole agent string, unless perhaps you find a reason where you need to tailor the website to a specific model.
You can check for iPhone, iPad and iPod in the agent string and cover all your bases.
if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
appleMobileDevice = true;
}
else {
appleMobileDevice = false;
}
The selected answer is correct but if you prefer to do this sort of thing in Interface Builder you can do this:
You could just give the first cell (therefore column) a width and have the rest default to auto
table {_x000D_
table-layout: fixed;_x000D_
border-collapse: collapse;_x000D_
width: 100%;_x000D_
}_x000D_
td {_x000D_
border: 1px solid #000;_x000D_
width: 150px;_x000D_
}_x000D_
td+td {_x000D_
width: auto;_x000D_
}
_x000D_

<td>150px</td>_x000D_
<td>equal</td>_x000D_
<td>equal</td>_x000D_
</tr>_x000D_
</table>
_x000D_
or alternatively the "proper way" to get column widths might be to use the col
element itself
table {_x000D_
table-layout: fixed;_x000D_
border-collapse: collapse;_x000D_
width: 100%;_x000D_
}_x000D_

border: 1px solid #000;_x000D_
}_x000D_
.wide {_x000D_

Since your example happens to be object-oriented, you could make the following change to achieve a similar result:
class PassByReference:
def __init__(self):
self.variable = 'Original'
self.change('variable')
print(self.variable)
def change(self, var):
setattr(self, var, 'Changed')
# o.variable will equal 'Changed'
o = PassByReference()
assert o.variable == 'Changed'
.input:focus {
outline: none !important;
border:1px solid red;
box-shadow: 0 0 10px #719ECE;
}
This structure (function() {})();
is called IIFE (Immediately Invoked Function Expression), it will be executed immediately, when the interpreter will reach this line. So when you're writing these rows:
(function($) {
// do something
})(jQuery);
this means, that the interpreter will invoke the function immediately, and will pass jQuery
as a parameter, which will be used inside the function as $
.
Convert numbers to words:
Here is an example in which numbers have been converted into words using the dictionary.
string = input("Enter a string: ")
my_dict = {'0': 'zero', '1': 'one', '2': 'two', '3': 'three', '4': 'four', '5': 'five', '6': 'six', '7': 'seven', '8': 'eight', '9': 'nine'}
for item in string:
if item in my_dict.keys():
string = string.replace(item, my_dict[item])
print(string)
Here is an alternative way if the data frame just contains numbers.
apply(as.matrix.noquote(SFI),2,as.numeric)
_x000D_
but the most reliable way of converting a data frame to a matrix is using data.matrix()
function.
It seems like JEP should do the job
You need to pass optimized: false
.
E.g.
var img = { url: 'img/puff.svg', scaledSide: new google.maps.Size(5, 5) };
new google.maps.Marker({position: this.mapOptions.center, map: this.map, icon: img, optimized: false,});
Without passing optimized: false
, my svg appeared as a static image.
If you have it in a string, you can use .split()
to separate them.
>>> for string in ('Mike 18', 'Kevin 35', 'Angel 56'):
... l = string.split()
... print repr(l[0]), repr(int(l[1]))
...
'Mike' 18
'Kevin' 35
'Angel' 56
>>>
If you're using JQuery you can do:
$('#elementid').click();
After weeks of research. I came up with the following code. I believe this is the bare minimum needed to make a secure connection with SSL to a web server.
#include <stdio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>
#include <openssl/bio.h>
#define APIKEY "YOUR_API_KEY"
#define HOST "YOUR_WEB_SERVER_URI"
#define PORT "443"
int main() {
//
// Initialize the variables
//
BIO* bio;
SSL* ssl;
SSL_CTX* ctx;
//
// Registers the SSL/TLS ciphers and digests.
//
// Basically start the security layer.
//
SSL_library_init();
//
// Creates a new SSL_CTX object as a framework to establish TLS/SSL
// or DTLS enabled connections
//
ctx = SSL_CTX_new(SSLv23_client_method());
//
// -> Error check
//
if (ctx == NULL)
{
printf("Ctx is null\n");
}
//
// Creates a new BIO chain consisting of an SSL BIO
//
bio = BIO_new_ssl_connect(ctx);
//
// Use the variable from the beginning of the file to create a
// string that contains the URL to the site that you want to connect
// to while also specifying the port.
//
BIO_set_conn_hostname(bio, HOST ":" PORT);
//
// Attempts to connect the supplied BIO
//
if(BIO_do_connect(bio) <= 0)
{
printf("Failed connection\n");
return 1;
}
else
{
printf("Connected\n");
}
//
// The bare minimum to make a HTTP request.
//
char* write_buf = "POST / HTTP/1.1\r\n"
"Host: " HOST "\r\n"
"Authorization: Basic " APIKEY "\r\n"
"Connection: close\r\n"
"\r\n";
//
// Attempts to write len bytes from buf to BIO
//
if(BIO_write(bio, write_buf, strlen(write_buf)) <= 0)
{
//
// Handle failed writes here
//
if(!BIO_should_retry(bio))
{
// Not worth implementing, but worth knowing.
}
//
// -> Let us know about the failed writes
//
printf("Failed write\n");
}
//
// Variables used to read the response from the server
//
int size;
char buf[1024];
//
// Read the response message
//
for(;;)
{
//
// Get chunks of the response 1023 at the time.
//
size = BIO_read(bio, buf, 1023);
//
// If no more data, then exit the loop
//
if(size <= 0)
{
break;
}
//
// Terminate the string with a 0, to let know C when the string
// ends.
//
buf[size] = 0;
//
// -> Print out the response
//
printf("%s", buf);
}
//
// Clean after ourselves
//
BIO_free_all(bio);
SSL_CTX_free(ctx);
return 0;
}
The code above will explain in details how to establish a TLS connection with a remote server.
Important note: this code doesn't check if the public key was signed by a valid authority. Meaning I don't use root certificates for validation. Don't forget to implement this check otherwise you won't know if you are connecting the right website
When it comes to the request itself. It is nothing more then writing the HTTP request by hand.
You can also find under this link an explanation how to instal openSSL in your system, and how to compile the code so it uses the secure library.
Another possibility is that you are missing an .npmrc
file if you are pulling any packages that are not publicly available.
You will need to add an .npmrc
file at the root directory and add the private/internal registry inside of the .npmrc
file like this:
registry=http://private.package.source/secret/npm-packages/
You can do this using the query builder. Just use SELECT instead of TABLE and GET.
DB::select('select * from user where name = ?',['Jhon']);
Notes: 1. Multiple question marks are allowed. 2. The second parameter must be an array, even if there is only one parameter. 3. Laravel will automatically clean parameters, so you don't have to.
Further info here: http://laravel.com/docs/5.0/database#running-queries
Hmmmmmm, turns out that still returns a standard class for me when I don't use a where clause. I found this helped:
foreach($results as $result)
{
print_r(get_object_vars($result));
}
However, get_object_vars isn't recursive, so don't use it on $results.
The normal method to send a file upload is POST, thus also post_max_size
should be 16 Mb or more.
Incidentally, also memory_limit
plays a role. It should be bigger than 16Mb, but since the default value is 128Mb, you won't see this problem. Example php.ini
configuration:
post_max_size = 16M
upload_max_filesize = 16M
memory_limit = 128M
Change these value in php.ini
if you've access to it, otherwise you can try to change them in an .htaccess
file.
php_value upload_max_filesize 16M
php_value post_max_size 16M
This will work only if the AllowOverride
settings permit it. Otherwise, you've to ask to your hosting company.
Alternatively via Project Settings:
Depending on how your build is set up, this may be the way to go.
There's another reason unserialize()
failed because you improperly put serialized data into the database see Official Explanation here. Since serialize()
returns binary data and php variables don't care encoding methods, so that putting it into TEXT, VARCHAR() will cause this error.
Solution: store serialized data into BLOB in your table.
Simply use
android:drawableTint="@color/primary_color"
in Your XML file. Replace primary_color to custom color
anUnicode.encode('encoding') results in a string object and can be called on a unicode object
aString.decode('encoding') results in an unicode object and can be called on a string, encoded in given encoding.
Some more explanations:
You can create some unicode object, which doesn't have any encoding set. The way it is stored by Python in memory is none of your concern. You can search it, split it and call any string manipulating function you like.
But there comes a time, when you'd like to print your unicode object to console or into some text file. So you have to encode it (for example - in UTF-8), you call encode('utf-8') and you get a string with '\u<someNumber>' inside, which is perfectly printable.
Then, again - you'd like to do the opposite - read string encoded in UTF-8 and treat it as an Unicode, so the \u360 would be one character, not 5. Then you decode a string (with selected encoding) and get brand new object of the unicode type.
Just as a side note - you can select some pervert encoding, like 'zip', 'base64', 'rot' and some of them will convert from string to string, but I believe the most common case is one that involves UTF-8/UTF-16 and string.
Unfortunately, the best thing I have seen is the jquery.combobox, but it doesn't really look like something I'd really want to use in my web applications. I think there are some usability issues with this control, but as a user I don't think I'd know to start typing for the dropdownlist to turn into a textbox.
I much prefer the Combo Dropdown Box, but it still has some features that I'd want and it's still in alpha. The only think I don't like about this other than its being alpha... is that once I type in the combobox, the original dropdownlist items disappear. However, maybe there is a setting for this... or maybe it could be added fairly easily.
Those are the only two options that I know of. Good luck in your search. I'd love to hear if you find one or if the second option works out for you.
Your JDK version: Java 8
Your JRE version: Java 9
Here your JRE version is different than the JDK version that's the case. Here you can compile all the java classes using JDK version 1.8. If you want to compile only one java class just change the *.java
into <yourclassname>.java
javac -source 1.8 -target 1.8 *.java
source: The version that your source code requires to compile.
target: The oldest JRE version you want to support.
You can use FormData to submit your data by a POST request. Here is a simple example:
var myFormData = new FormData();
myFormData.append('pictureFile', pictureInput.files[0]);
$.ajax({
url: 'upload.php',
type: 'POST',
processData: false, // important
contentType: false, // important
dataType : 'json',
data: myFormData
});
You don't have to use a form to make an ajax request, as long as you know your request setting (like url, method and parameters data).
Well it depends, if you want to bind datas, there shouldn't be any formatting in it, otherwise you can bind-html
and do description.replace(/\\n/g, '<br>')
not sure it's what you want though.
These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.
But if you have to send non-ASCII text or large binary data, the form-data is for that.
You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.
Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.
Refer to this link for further reading: Forms in HTML documents
When dealing with marker clusters this one worked for me.
var infowindow = null;
google.maps.event.addListener(marker, "click", function () {
if (infowindow) {
infowindow.close();
}
var markerMap = this.getMap();
infowindow = this.info;
this.info.open(markerMap, this);
});
That is because FirstOrDefault
can return null
causing your following .Value
to cause the exception. You need to change it to something like:
var myThing = things.FirstOrDefault(t => t.Id == idToFind);
if(myThing == null)
return; // we failed to find what we wanted
var displayName = myThing.DisplayName;
https://turbo.net/ offers a browser sandbox in which containerised virtual machines run browser sessions for you. I tried it with Safari on my Windows development machine and it seems to work very well.
No import is necessary as long as you declare both a.go
and b.go
to be in the same package. Then, you can use go run
to recognize multiple files with:
$ go run a.go b.go
align-content
align-content
controls the cross-axis (i.e. vertical direction if the flex-direction
is row
, and horizontal if the flex-direction
is column
) positioning of multiple lines relative to each other.
(Think lines of a paragraph being vertically spread out, stacked toward the top, stacked toward the bottom. This is under a flex-direction
row paradigm).
align-items
align-items
controls the cross-axis of an individual line of flex elements.
(Think how an individual line of a paragraph is aligned, if it contains some normal text and some taller text like math equations. In that case, will it be the bottom, top, or center of each type of text in a line that will be aligned?)
I used this tutorial to create my maven web project http://crunchify.com/how-to-create-dynamic-web-project-using-maven-in-eclipse/ and eclipse did not create src/main/java folder for me. When i tired to create the source folder src/main/java eclipse did not let me. So i created the folder outside eclipse in the project directly and then src/main/java appeared in eclipse.
try to find your log file with suffix ".err", there should be more info. It might be in:
/usr/local/var/mysql/your_computer_name.local.err
It's probably problem with permissions
check if any mysql instance is running
ps -ef | grep mysql
if yes, you should stop it, or kill the process
kill -9 PID
where PID
is the number displayed next to username on output of previous command
check ownership of /usr/local/var/mysql/
ls -laF /usr/local/var/mysql/
if it is owner by root
you should change it mysql
or your_user
sudo chown -R mysql /usr/local/var/mysql/
You would define a constructor in an abstract class if you are in one of these situations:
Note that:
In any case, don't forget that if you don't define a constructor, then the compiler will automatically generate one for you (this one is public, has no argument, and does nothing).
Set this in your XML code, It works.
android:focusableInTouchMode="false"
If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.
Check host entries in your host file
%windir%/system32/drivers/etc/hosts
Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.
Try either of the following
Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861

There are several ways to do plots in R; lattice
is one of them, and always a reasonable solution, +1 to @agstudy. If you want to do this in base graphics, you could try the following:
Reasonstats <- read.table(text="Category Reason Species
Decline Genuine 24
Improved Genuine 16
Improved Misclassified 85
Decline Misclassified 41
Decline Taxonomic 2
Improved Taxonomic 7
Decline Unclear 41
Improved Unclear 117", header=T)
ReasonstatsDec <- Reasonstats[which(Reasonstats$Category=="Decline"),]
ReasonstatsImp <- Reasonstats[which(Reasonstats$Category=="Improved"),]
Reasonstats3 <- cbind(ReasonstatsImp[,3], ReasonstatsDec[,3])
colnames(Reasonstats3) <- c("Improved", "Decline")
rownames(Reasonstats3) <- ReasonstatsImp$Reason
windows()
barplot(t(Reasonstats3), beside=TRUE, ylab="number of species",
cex.names=0.8, las=2, ylim=c(0,120), col=c("darkblue","red"))
box(bty="l")
Here's what I did: I created a matrix with two columns (because your data were in columns) where the columns were the species counts for Decline
and for Improved
. Then I made those categories the column names. I also made the Reason
s the row names. The barplot()
function can operate over this matrix, but wants the data in rows rather than columns, so I fed it a transposed version of the matrix. Lastly, I deleted some of your arguments to your barplot()
function call that were no longer needed. In other words, the problem was that your data weren't set up the way barplot()
wants for your intended output.
A query string is an array of parameters sent to a web page.
This url: http://page.asp?x=1&y=hello
Request.QueryString[0] is the same as
Request.QueryString["x"] and holds a string value "1"
Request.QueryString[1] is the same as
Request.QueryString["y"] and holds a string value "hello"
You don't need to wrap it in a list with [..]
, just provide the subselection of the columns index:
df.drop(df.columns[[1, 69]], axis=1, inplace=True)
as the index object is already regarded as list-like.
The other solutions didn't work for me. Maybe the old DOCTYPE in the project I am working on prevents HTML5 options.
My solution:
<form id="form_1" action="result.php" method="post"
onsubmit="sendForm(this.id);return false">
<input type="hidden" name="something" value="1">
</form>
js:
function sendForm(form_id){
var form = $('#'+form_id);
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: $(form).serialize(),
success: function(result) {
console.log(result)
}
});
}
Both FetchType.LAZY
and FetchType.EAGER
are used to define the default fetch plan.
Unfortunately, you can only override the default fetch plan for LAZY fetching. EAGER fetching is less flexible and can lead to many performance issues.
My advice is to restrain the urge of making your associations EAGER because fetching is a query-time responsibility. So all your queries should use the fetch directive to only retrieve what's necessary for the current business case.
// set
$_SESSION['test'] = 1;
// destroy
unset($_SESSION['test']);
There isn't currently a better way to do it than Ctrl+C in the terminal.
We're thinking about how to have an explicit shutdown, but there's some tension between the notebook as a single-user application, where the user is free to stop it, and as a multi-user server, where only an admin should be able to stop it. We haven't quite worked out how to handle the differences yet.
(For future readers, this is the situation with 0.12 released and 0.13 in development.)
Update December 2017
The IPython Notebook has become the Jupyter Notebook. A recent version has added a jupyter notebook stop
shell command which will shut down a server running on that system. You can pass the port number at the command line if it's not the default port 8888.
You can also use nbmanager, a desktop application which can show running servers and shut them down.
Finally, we are working on adding:
Remove @ResponseBody annotation from your use parameters in method. Like this;
@Autowired
ProjectService projectService;
@RequestMapping(path = "/add", method = RequestMethod.POST)
public ResponseEntity<Project> createNewProject(Project newProject){
Project project = projectService.save(newProject);
return new ResponseEntity<Project>(project,HttpStatus.CREATED);
}
Do this:
<video style="display:block; margin: 0 auto;" controls>....</video>
Works perfect! :D
Put this code in your .htaccess file
RewriteEngine On
ErrorDocument 404 /404.php
where 404.php

This is how I solve my problem:
parseFloat(parseFloat(floatString).toFixed(2));

set pagesize 0;
set linesize 150;

spool off;
exit;

Looks like the script executes before the DOM loads. Try loading the script asynchronously.
<script src="yourcode.js" async></script>
Try this
$('#D25,#E37,#E31,#F37,#E16,#E40,#F16,#F40,#E41,#F41').bind('DOMNodeInserted DOMNodeRemoved',function(){
// your code;
});
Do not use this. This may crash the page.
$('mydiv').bind("DOMSubtreeModified",function(){
alert('changed');
});
What you have coded is not a LinkedList, at least not one that I recognize. For this assignment, you want to create two classes:
LinkNode
LinkedList
A LinkNode
has one member field for the data it contains, and a LinkNode
reference to the next LinkNode
in the LinkedList
. Yes, it's a self referential data structure. A LinkedList
just has a special LinkNode
reference that refers to the first item in the list.
When you add an item in the LinkedList
, you traverse all the LinkNode's
until you reach the last one. This LinkNode's
next should be null. You then construct a new LinkNode
here, set it's value, and add it to the LinkedList
.
public class LinkNode {
String data;
LinkNode next;
public LinkNode(String item) {
data = item;
}
}
public class LinkedList {
LinkNode head;
public LinkedList(String item) {
head = new LinkNode(item);
}
public void add(String item) {
//pseudo code: while next isn't null, walk the list
//once you reach the end, create a new LinkNode and add the item to it. Then
//set the last LinkNode's next to this new LinkNode
}
}
If you want to check if a string contains substring or not using regex, the closest you can do is by using find() -
private static final validPattern = "\\bstores\\b.*\\bstore\\b.*\\bproduct\\b"
Pattern pattern = Pattern.compile(validPattern);
Matcher matcher = pattern.matcher(inputString);
System.out.print(matcher.find()); // should print true or false.
Note the difference between matches() and find(), matches() return true if the whole string matches the given pattern. find() tries to find a substring that matches the pattern in a given input string. Also by using find() you don't have to add extra matching like - (?s).* at the beginning and .* at the end of your regex pattern.

The best solution is to override the click functionality:
public void _click(WebElement element){
boolean flag = false;
while(true) {
try{
element.click();
flag=true;
}
catch (Exception e){
flag = false;
}
if(flag)
{
try{
element.click();
}
catch (Exception e){
System.out.printf("Element: " +element+ " has beed clicked, Selenium exception triggered: " + e.getMessage());
}
break;
}
}
}
function my_get_tags_sitemap(){
if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
$unlinkTags = get_option('cb2_unlinkTags');
echo '<div class="tags"><h2>Tags</h2>';
$ret = []; // here you need to add array which you call inside implode function
if($unlinkTags)
{
$tags = get_tags();
foreach ($tags as $tag){
$ret[]= $tag->name;
}
//ERROR OCCURS HERE
echo implode(', ', $ret);
}
else
{
wp_tag_cloud('separator=, &smallest=11&largest=11');
}
echo '</div>';
}
Add the following code within the constructor like so:
public Calculator() {
initComponents();
//the code to be added this.setIconImage(newImageIcon(getClass().getResource("color.png")).getImage()); }
Change "color.png" to the file name of the picture you want to insert. Drag and drop this picture onto the package (under Source Packages) of your project.
Run your project.
You can extend the string type to include the inset method:
String.prototype.append = function (index,value) {_x000D_
return this.slice(0,index) + value + this.slice(index);_x000D_
};_x000D_
_x000D_
var s = "New string";_x000D_
alert(s.append(4,"complete "));
_x000D_
Then you can call the function:
My templatized inline in-place find-and-replace:
template<class T>
int inline findAndReplace(T& source, const T& find, const T& replace)
{
int num=0;
typename T::size_t fLen = find.size();
typename T::size_t rLen = replace.size();
for (T::size_t pos=0; (pos=source.find(find, pos))!=T::npos; pos+=rLen)
{
num++;
source.replace(pos, fLen, replace);
}
return num;
}
It returns a count of the number of items substituted (for use if you want to successively run this, etc). To use it:
std::string str = "one two three";
int n = findAndReplace(str, "one", "1");
I would like to provide a different perspective on what "git pull --rebase" actually means, because it seems to get lost sometimes.
If you've ever used Subversion (or CVS), you may be used to the behavior of "svn update". If you have changes to commit and the commit fails because changes have been made upstream, you "svn update". Subversion proceeds by merging upstream changes with yours, potentially resulting in conflicts.
What Subversion just did, was essentially "pull --rebase". The act of re-formulating your local changes to be relative to the newer version is the "rebasing" part of it. If you had done "svn diff" prior to the failed commit attempt, and compare the resulting diff with the output of "svn diff" afterwards, the difference between the two diffs is what the rebasing operation did.
The major difference between Git and Subversion in this case is that in Subversion, "your" changes only exist as non-committed changes in your working copy, while in Git you have actual commits locally. In other words, in Git you have forked the history; your history and the upstream history has diverged, but you have a common ancestor.
In my opinion, in the normal case of having your local branch simply reflecting the upstream branch and doing continuous development on it, the right thing to do is always "--rebase", because that is what you are semantically actually doing. You and others are hacking away at the intended linear history of a branch. The fact that someone else happened to push slightly prior to your attempted push is irrelevant, and it seems counter-productive for each such accident of timing to result in merges in the history.
If you actually feel the need for something to be a branch for whatever reason, that is a different concern in my opinion. But unless you have a specific and active desire to represent your changes in the form of a merge, the default behavior should, in my opinion, be "git pull --rebase".
Please consider other people that need to observe and understand the history of your project. Do you want the history littered with hundreds of merges all over the place, or do you want only the select few merges that represent real merges of intentional divergent development efforts?
This will do:
/^(apple|banana)$/
to exclude from captured strings (e.g. $1
,$2
):
(?:apple|banana)
My version for a directive that uses jqplot to plot the data once it becomes available:
app.directive('lineChart', function() {
$.jqplot.config.enablePlugins = true;
return function(scope, element, attrs) {
scope.$watch(attrs.lineChart, function(newValue, oldValue) {
if (newValue) {
// alert(scope.$eval(attrs.lineChart));
var plot = $.jqplot(element[0].id, scope.$eval(attrs.lineChart), scope.$eval(attrs.options));
}
});
}
});
When you start in Cygwin you are in the "/home/Administrator" zone, so put your a.exe file there.
Then at the prompt run:
cd a.exe
It will be read in by Cygwin and you will be asked to install it.
you can test this:
let newString = test.stringByReplacingOccurrencesOfString(" ", withString: "+", options: nil, range: nil)
I found this to work flawlessly if you want to share whole screen.
@IBAction func shareButton(_ sender: Any) {
let bounds = UIScreen.main.bounds
UIGraphicsBeginImageContextWithOptions(bounds.size, true, 0.0)
self.view.drawHierarchy(in: bounds, afterScreenUpdates: false)
let img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
let activityViewController = UIActivityViewController(activityItems: [img!], applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
self.present(activityViewController, animated: true, completion: nil)
}
git commit --amend --date="now"
@Limp, your answer is right, just use .nextLine() while reading the input. Sample code:
do {
try {
System.out.println("Enter first num: ");
n1 = Integer.parseInt(input.nextLine());
System.out.println("Enter second num: ");
n2 = Integer.parseInt(input.nextLine());
nQuotient = n1 / n2;
bError = false;
} catch (Exception e) {
System.out.println("Error!");
}
} while (bError);
System.out.printf("%d/%d = %d", n1, n2, nQuotient);
Read the description of why this problem was caused in the link below. Look for the answer I posted for the detail in this thread. Java Homework user input issue
Ok, I will briefly describe it. When you read input using nextInt(), you just read the number part but the ENDLINE character was still on the stream. That was the main cause. Now look at the code above, all I did is read the whole line and parse it , it still throws the exception and work the way you were expecting it to work. Rest of your code works fine.
With React Functional way
import React, { useEffect } from "react";
import ReactDOM from "react-dom";
import Button from "@material-ui/core/Button";
const App = () => {
const saySomething = (something) => {
console.log(something);
};
useEffect(() => {
saySomething("from useEffect");
});
const handleClick = (e) => {
saySomething("element clicked");
};
return (
<Button variant="contained" color="primary" onClick={handleClick}>
Hello World
</Button>
);
};
ReactDOM.render(<App />, document.querySelector("#app"));
There is no standard assert
in JavaScript itself. Perhaps you're using some library that provides one; for instance, if you're using Node.js, perhaps you're using the assertion module. (Browsers and other environments that offer a console implementing the Console API provide console.assert
.)
The usual meaning of an assert
function is to throw an error if the expression passed into the function is false; this is part of the general concept of assertion checking. Usually assertions (as they're called) are used only in "testing" or "debug" builds and stripped out of production code.
Suppose you had a function that was supposed to always accept a string. You'd want to know if someone called that function with something that wasn't a string (without having a type checking layer like TypeScript or Flow). So you might do:
assert(typeof argumentName === "string");
...where assert
would throw an error if the condition were false.
A very simple version would look like this:
function assert(condition, message) {
if (!condition) {
throw message || "Assertion failed";
}
}
Better yet, make use of the Error
object, which has the advantage of collecting a stack trace and such:
function assert(condition, message) {
if (!condition) {
throw new Error(message || "Assertion failed");
}
}
You can use array_intersect()
.
$result = !empty(array_intersect($people, $criminals));
In case you want to write fallback code, decoding from base64 has been present in iOS since the very beginning by caveat of NSURL
:
NSURL *URL = [NSURL URLWithString:
[NSString stringWithFormat:@"data:application/octet-stream;base64,%@",
base64String]];
return [NSData dataWithContentsOfURL:URL];
Use the URI
class.
Create a new URI
with your existing String
to "break it up" to parts, and instantiate another one to assemble the modified url:
URI u = new URI("http://[email protected]&name=John#fragment");
// Modify the query: append your new parameter
StringBuilder sb = new StringBuilder(u.getQuery() == null ? "" : u.getQuery());
if (sb.length() > 0)
sb.append('&');
sb.append(URLEncoder.encode("paramName", "UTF-8"));
sb.append('=');
sb.append(URLEncoder.encode("paramValue", "UTF-8"));
// Build the new url with the modified query:
URI u2 = new URI(u.getScheme(), u.getAuthority(), u.getPath(),
sb.toString(), u.getFragment());
You can use another overload of the DropDownList
method. Pick the one you need and pass in
a object with your html attributes.
@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })
I usually use numpy sum over the logical condition column:
>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)
2
This seems to me slightly shorter than the solution presented above
The rules for new
are analogous to what happens when you initialize an object with automatic storage duration (although, because of vexing parse, the syntax can be slightly different).
If I say:
int my_int; // default-initialize ? indeterminate (non-class type)
Then my_int
has an indeterminate value, since it is a non-class type. Alternatively, I can value-initialize my_int
(which, for non-class types, zero-initializes) like this:
int my_int{}; // value-initialize ? zero-initialize (non-class type)
(Of course, I can't use ()
because that would be a function declaration, but int()
works the same as int{}
to construct a temporary.)
Whereas, for class types:
Thing my_thing; // default-initialize ? default ctor (class type)
Thing my_thing{}; // value-initialize ? default-initialize ? default ctor (class type)
The default constructor is called to create a Thing
, no exceptions.
So, the rules are more or less:
{}
) or default-initialized (without {}
). (There is some additional prior zeroing behavior with value-initialization, but the default constructor is always given the final say.){}
used?
These rules translate precisely to new
syntax, with the added rule that ()
can be substituted for {}
because new
is never parsed as a function declaration. So:
int* my_new_int = new int; // default-initialize ? indeterminate (non-class type)
Thing* my_new_thing = new Thing; // default-initialize ? default ctor (class type)
int* my_new_zeroed_int = new int(); // value-initialize ? zero-initialize (non-class type)
my_new_zeroed_int = new int{}; // ditto
my_new_thing = new Thing(); // value-initialize ? default-initialize ? default ctor (class type)
(This answer incorporates conceptual changes in C++11 that the top answer currently does not; notably, a new scalar or POD instance that would end up an with indeterminate value is now technically now default-initialized (which, for POD types, technically calls a trivial default constructor). While this does not cause much practical change in behavior, it does simplify the rules somewhat.)
This works on SQL Server 2000.
use master
select count(*) From sysxlogins WHERE NAME = 'myUsername'
on SQL 2005, change the 2nd line to
select count(*) From syslogins WHERE NAME = 'myUsername'
I'm not sure about SQL 2008, but I'm guessing that it will be the same as SQL 2005 and if not, this should give you an idea of where t start looking.
I had this error in Windows 10. I followed these three steps and it solved my problem:
Install nbconvert
pip install nbconvert
Install pandoc
https://pandoc.org/installing.html
Also it is good to update libraries:
pip install jupyter --upgrade
pip install --upgrade --user nbconvert
If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:
width = 12
height = 12
plt.figure(figsize=(width, height))
One simple approach I have used is conditional rendering:
@(Model.ExpireDate == null ?
@Html.TextBoxFor(m => m.ExpireDate, new { @disabled = "disabled" }) :
@Html.TextBoxFor(m => m.ExpireDate)
)
I faced the same problem.
Just removed the server from configuration and added it back after restarting eclipse by adding it to the server runtime environment.
Careful - append()
will append HTML, and you may run into cross-site-scripting problems if you use it all the time and a user makes you append('<script>alert("Hello")</script>')
.
Use text()
to replace element content with text, or append(document.createTextNode(x))
to append a text node.
The single-step answer to the first question is to use something like:
update TBL set CLM = CLM + 1 where key = 'KEY'
That's very much a single-instruction way of doing it.
As for the second question, you shouldn't need to resort to DBMS-specific SQL gymnastics (like UPSERT
) to get the result you want. There's a standard method to do update-or-insert that doesn't require a specific DBMS.
try:
insert into TBL (key,val) values ('xyz',0)
catch:
do nothing
update TBL set val = val + 1 where key = 'xyz'
That is, you try to do the creation first. If it's already there, ignore the error. Otherwise you create it with a 0 value.
Then do the update which will work correctly whether or not:
It's not a single instruction and yet, surprisingly enough, it's how we've been doing it successfully for a long long time.
