I am using the following code in one of my current projects where i download data from the internet. It is all inside my activity class.
// ---------------------------- START DownloadFileAsync // -----------------------//
class DownloadFileAsync extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
// DIALOG_DOWNLOAD_PROGRESS is defined as 0 at start of class
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
@Override
protected String doInBackground(String... urls) {
try {
String xmlUrl = urls[0];
URL u = new URL(xmlUrl);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
int lengthOfFile = c.getContentLength();
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
long total = 0;
while ((len1 = in.read(buffer)) > 0) {
total += len1; // total = total + len1
publishProgress("" + (int) ((total * 100) / lengthOfFile));
xmlContent += buffer;
}
} catch (Exception e) {
Log.d("Downloader", e.getMessage());
}
return null;
}
protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC", progress[0]);
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
@Override
protected void onPostExecute(String unused) {
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
}
}
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Retrieving latest announcements...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.setMax(100);
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(true);
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}
This is a common problem.
Use this
instead of getApplicationContext()
That should solve your problem
Yes, in API level 26
it's deprecated. Instead, you can use progressBar
.
To create it programmatically:
First get a reference to the root layout
RelativeLayout layout = findViewById(R.id.display); //specify here Root layout Id
or
RelativeLayout layout = findViewById(this);
Then add the progress bar
progressBar = new ProgressBar(youractivity.this, null, android.R.attr.progressBarStyleLarge);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(100, 100);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
layout.addView(progressBar, params);
To show the progress bar
progressBar.setVisibility(View.VISIBLE);
To hide the progress bar
progressBar.setVisibility(View.GONE);
To disable the user interaction you just need to add the following code
getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
To get user interaction back you just need to add the following code
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
Just for future reference, change the android.R.attr.progressBarStyleSmall
to android.R.attr.progressBarStyleHorizontal
.
The code below only works above API level 21
progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
To create it via xml:
<ProgressBar
android:id="@+id/progressbar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:indeterminate="true"
android:max="100"
android:backgroundTint="@color/white"
android:layout_below="@+id/framelauout"
android:indeterminateTint="#1a09d6"
android:layout_marginTop="-7dp"/>
In your activity
progressBar = (ProgressBar) findViewById(R.id.progressbar);
Showing/hiding the progress bar is the same
progressBar.setVisibility(View.VISIBLE); // To show the ProgressBar
progressBar.setVisibility(View.INVISIBLE); // To hide the ProgressBar
Here is a sample image of what it would look like:

I had a hard time making this work too, the solution for me was to use both hyui and konstantin answers,
class ExampleTask extends AsyncTask<String, String, String> {
// Your onPreExecute method.
@Override
protected String doInBackground(String... params) {
// Your code.
if (condition_is_true) {
this.publishProgress("Show the dialog");
}
return "Result";
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
YourActivity.this.runOnUiThread(new Runnable() {
public void run() {
alertDialog.show();
}
});
}
}
A lot of Developers including have hard time at the beginning writing an AsyncTask because of the ambiguity of the parameters. The big reason is we try to memorize the parameters used in the AsyncTask. The key is Don't memorize. If you can visualize what your task really needs to do then writing the AsyncTask with the correct signature would be a piece of cake.
AsyncTask are background task which run in the background thread. It takes an Input, performs Progress and gives Output.
ie
AsyncTask<Input,Progress,Output>
Just figure out what your Input, Progress and Output are and you will be good to go.
For example
How does
doInbackground()
changes withAsyncTask
parameters?
How
doInBackground()
andonPostExecute()
,onProgressUpdate()
are related?
How can You write this in a code?
DownloadTask extends AsyncTask<String,Integer,String>{
@Override
public void onPreExecute(){
}
@Override
public String doInbackGround(String... params)
{
// Download code
int downloadPerc = // calculate that
publish(downloadPerc);
return "Download Success";
}
@Override
public void onPostExecute(String result)
{
super.onPostExecute(result);
}
@Override
public void onProgressUpdate(Integer... params)
{
// show in spinner, access UI elements
}
}
How will you run this Task in Your Activity?
new DownLoadTask().execute("Paradise.mp3");
I sort of agree with leander on this one.
call:
new calc_stanica().execute(stringList.toArray(new String[stringList.size()]));
task:
public class calc_stanica extends AsyncTask<String, Void, ArrayList<String>> {
@Override
protected ArrayList<String> doInBackground(String... args) {
...
}
@Override
protected void onPostExecute(ArrayList<String> result) {
... //do something with the result list here
}
}
Or you could just make the result list a class parameter and replace the ArrayList with a boolean (success/failure);
public class calc_stanica extends AsyncTask<String, Void, Boolean> {
private List<String> resultList;
@Override
protected boolean doInBackground(String... args) {
...
}
@Override
protected void onPostExecute(boolean success) {
... //if successfull, do something with the result list here
}
}
Custom progress with scale!
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:duration="150">
<scale
android:drawable="@drawable/face_no_smile_eyes_off"
android:scaleGravity="center" />
</item>
<item android:duration="150">
<scale
android:drawable="@drawable/face_no_smile_eyes_on"
android:scaleGravity="center" />
</item>
<item android:duration="150">
<scale
android:drawable="@drawable/face_smile_eyes_off"
android:scaleGravity="center" />
</item>
<item android:duration="150">
<scale
android:drawable="@drawable/face_smile_eyes_on"
android:scaleGravity="center" />
</item>
</animation-list>
This is the good way to use dialog
private class YourAsyncTask extends AsyncTask<Void, Void, Void> {
ProgressDialog dialog = new ProgressDialog(IncidentFormActivity.this);
@Override
protected void onPreExecute() {
//set message of the dialog
dialog.setMessage("Loading...");
//show dialog
dialog.show();
super.onPreExecute();
}
protected Void doInBackground(Void... args) {
// do background work here
return null;
}
protected void onPostExecute(Void result) {
// do UI work here
if(dialog != null && dialog.isShowing()){
dialog.dismiss()
}
}
}
You can try this code into your activity
private void startWebView(WebView webView,String url) {
webView.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog;
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
public void onLoadResource (WebView view, String url) {
if (progressDialog == null) {
progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
}
}
public void onPageFinished(WebView view, String url) {
try{
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
}catch(Exception exception){
exception.printStackTrace();
}
}
});
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
Call this method using this way:
startWebView(web_view,"Your Url");
Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.
Thanks :)

You can use Apache Commons Configuration library. The best part of this is, it won't even mess up the properties file and keeps it intact (even comments).
PropertiesConfiguration conf = new PropertiesConfiguration("propFile.properties");
conf.setProperty("key", "value");
conf.save();
Some of the answers above, in regards to linux, are either incomplete, or flat out wrong.
For example, /usr/include/GL/gl.h is not part of mesa-common-dev or has not been for many years.
At any rate, for a more current answer, these two packages are important:
https://mesa.freedesktop.org/archive/mesa-20.1.2.tar.xz
ftp://ftp.freedesktop.org/pub/mesa/glu/glu-9.0.1.tar.xz
The glu.h is part of glu itself:
GL/glu.h
GL/glu_mangle.h
Mesa is evidently significantly larger. Its headers are a bit variable, I suppose, depending on the flags given to meson, but should include these typically:
KHR/khrplatform.h
EGL/eglplatform.h
EGL/eglext.h
EGL/eglextchromium.h
EGL/eglmesaext.h
EGL/egl.h
vulkan/vulkan_intel.h

Hope that helps anyone finding an answer this question in the future; compiling dosbox needs this, for instance, due to SDL opengl.
Use a white space to match all descendants of an element:
div.dropdown * {
color: red;
}
x y
matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.
The asterisk *
matches any element.

Add { } while importing and exporting:
export { ... };
|
import { ... } from './Template';
export → import { ... } from './Template'
export default → import ... from './Template'
Here is a working example:
// ExportExample.js
import React from "react";
function DefaultExport() {
return "This is the default export";
}
function Export1() {
return "Export without default 1";
}
function Export2() {
return "Export without default 2";
}
export default DefaultExport;
export { Export1, Export2 };
// App.js
import React from "react";
import DefaultExport, { Export1, Export2 } from "./ExportExample";
export default function App() {
return (
<>
<strong>
<DefaultExport />
</strong>
<br />
<Export1 />
<br />
<Export2 />
</>
);
}

Small tweak to Luke's answer,
function reloadJs(src) {
src = $('script[src$="' + src + '"]').attr("src");
$('script[src$="' + src + '"]').remove();
$('<script/>').attr('src', src).appendTo('head');
}
and call it like,
reloadJs("myFile.js");
This will not have any path related issues.
There are at least two ways to do it:
Use nowrap attribute inside the "td" tag:
<th nowrap="nowrap">Really long column heading</th>
Use non-breakable spaces between your words:
<th>Really long column heading</th>
You may want to take if from a diffrent side: It seems easier to have a TextView with a drawable on the background:
<TextView
android:id="@+id/text"
android:background="@drawable/rounded_rectangle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
</TextView>
I don't think you need/want the timeout.
onhover (hover) would be defined as the time period while "over" something. IMHO
onmouseover = start...
onmouseout = ...end
For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.
I got the same problem, and the solution is very simple: don't start a new line! Although some of the previous answers can solve the problem, the idea is not stated clearly. The important understanding is, to get rid of the unintended spaces, never start a new line just after your start tag.
The following way is WRONG and will leave a lot of unwanted spaces before your text content:
<textarea>
text content // start with a new line will leave a lot of unwanted spaces
</textarea>
The RIGHT WAY to do it is:
<textarea>text content //put text content right after your start tag, no new line
</textarea>
byte[] byteArray = new byte[102400];
base64String = Base64.encode(byteArray);
That code will encode 102400 bytes, no matter how much data you actually use in the array.
while ((bytesRead = fis.read(byteArray)) != -1)
You need to use the value of bytesRead somewhere.
Also, this may not read the whole file into the array in one go (it only reads as much as is in the I/O buffer), so your loop will probably not work, you may end up with half an image in your array.
I'd use Apache Commons IOUtils here:
Base64.encode(FileUtils.readFileToByteArray(file));
Try figsize

df.plot(figsize=(5,3));
The size in figsize=(5,3)

This blog post by Jean-Paul Calderone is commonly given as an answer in #python on Freenode.
Filesystem structure of a Python project
Do:
- name the directory something related to your project. For example, if your project is named "Twisted", name the top-level directory for its source files
Twisted
. When you do releases, you should include a version number suffix:Twisted-2.5
.- create a directory
Twisted/bin
and put your executables there, if you have any. Don't give them a.py
extension, even if they are Python source files. Don't put any code in them except an import of and call to a main function defined somewhere else in your projects. (Slight wrinkle: since on Windows, the interpreter is selected by the file extension, your Windows users actually do want the .py extension. So, when you package for Windows, you may want to add it. Unfortunately there's no easy distutils trick that I know of to automate this process. Considering that on POSIX the .py extension is a only a wart, whereas on Windows the lack is an actual bug, if your userbase includes Windows users, you may want to opt to just have the .py extension everywhere.)- If your project is expressable as a single Python source file, then put it into the directory and name it something related to your project. For example,
Twisted/twisted.py
. If you need multiple source files, create a package instead (Twisted/twisted/
, with an emptyTwisted/twisted/__init__.py
) and place your source files in it. For example,Twisted/twisted/internet.py
.- put your unit tests in a sub-package of your package (note - this means that the single Python source file option above was a trick - you always need at least one other file for your unit tests). For example,
Twisted/twisted/test/
. Of course, make it a package withTwisted/twisted/test/__init__.py
. Place tests in files likeTwisted/twisted/test/test_internet.py
.- add
Twisted/README
andTwisted/setup.py
to explain and install your software, respectively, if you're feeling nice.Don't:
- put your source in a directory called
src
orlib
. This makes it hard to run without installing.- put your tests outside of your Python package. This makes it hard to run the tests against an installed version.
- create a package that only has a
__init__.py
and then put all your code into__init__.py
. Just make a module instead of a package, it's simpler.- try to come up with magical hacks to make Python able to import your module or package without having the user add the directory containing it to their import path (either via PYTHONPATH or some other mechanism). You will not correctly handle all cases and users will get angry at you when your software doesn't work in their environment.
I thought I'd try code this up for fun:
graph = {
'1': ['2', '3', '4'],
'2': ['5', '6'],
'5': ['9', '10'],
'4': ['7', '8'],
'7': ['11', '12']
}
def bfs(graph, forefront, end):
# assumes no cycles
next_forefront = [(node, path + ',' + node) for i, path in forefront if i in graph for node in graph[i]]
for node,path in next_forefront:
if node==end:
return path
else:
return bfs(graph,next_forefront,end)
print bfs(graph,[('1','1')],'11')
# >>>
# 1, 4, 7, 11
If you want cycles you could add this:
for i, j in for_front: # allow cycles, add this code
if i in graph:
del graph[i]
ADD go /usr/local/
will copy the contents of your local go
directory in the /usr/local/
directory of your docker image.
To copy the go
directory itself in /usr/local/
use:
ADD go /usr/local/go
or
COPY go /usr/local/go
Also check this article. Supposedly Microsoft released their Enterprise Library (v4.0) from their patterns and practices where they cover the validation subject but god knows why they didn't included validation for WPF, so the blog post I'm directing you to, explains what the author did to adapt it. Hope this helps!
DEFINITION:: Gradle can be described a structured building mechanism where it provides a developer the tools and flexibility to manage the resources of a project to create builds that are smaller in size
, targeting specific requirements
for certain devices of certain configurations
BASIC CONFIGURATIONS
minimumSdk
maximumSdk
targettedSdk
versionCode
versionName
LIBRARIES:: We can add android libraries or any other third party libraries in addition as per requirements easy which was a tedious task earlier. If the library does not fit for the existing project, The developer is shown a log where the person can find a appropriate solution to make changes to the project so that the library can be added. Its just one line of dependency
GENERATING VARIETIES OF BUILDS
Combining build types with build flavours to get varities of build varients
==================== ====================
| BuildTypes | | ProductFlavours |
-------------------- ====================== --------------------
| Debug,Production | || || | Paid,Free,Demo,Mock|
==================== || || ====================
|| ||
VV VV
=================================================================
| DebugPaid, DebugFree, DebugDemo, DebugMock |
| ProductionPaid, ProductionFree, ProductionDemo, ProductionMock |
=================================================================
REDUCING SIZE
Gradle helps in reducing the size of the generated build by removing the unused resources also unused things from integrated libraries
MANAGING PERMISSIONS
We can Specify certain permissions for certain builds by adding certain permissions in certain scenarios based on requirements
BUILDS FOR CERTAIN DEVICES
We can manage generating build for certain devices that include certain densities and certain api levels. This helps in product deployments in app store according to requirements across multiple types of devices
GOOD REFERENCE
The output of dpkg -s ...
demonstrates that docker-compose
is not installed from a package. Without more information from you there are at least two possibilities:
docker-compose simply isn't installed at all, and you need to install it.
The solution here is simple: install docker-compose
.
docker-compose is installed in your $HOME
directory (or other location not on root's $PATH
).
There are several solution in this case. The easiest is probably to replace:
sudo docker-compose ...
With:
sudo `which docker-compose` ...
This will call sudo
with the full path to docker-compose
.
You could alternatively install docker-compose
into a system-wide directory, such as /usr/local/bin
.
If you're using eclipse you can open default.properties
file in your workspace and change the project target to the new sdk (target=android-8
for 2.2). I accidentally selected the 1.5 sdk for my version and didn't catch it until much later, but updating that and restarting eclipse seemed to have done the trick.
after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:
<Directory "c:/wamp/www"><!-- maybe other url-->
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.4/mod/core.html#options
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# AllowOverride FileInfo AuthConfig Limit
#
AllowOverride All
#
# Controls who can get stuff from this server.
#
# Require all granted
# onlineoffline tag - don't remove
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
Allow from localhost
</Directory>
3- Change to: Deny from none
like this:
<Directory "c:/wamp/www">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

#
# Require all granted

4- Restart Apache
Don't forget restart Apache or all servises!!!
Using dynamic object with JavaScriptSerializer.
JavaScriptSerializer serializer = new JavaScriptSerializer();
dynamic item = serializer.Deserialize<object>("{ \"test\":\"some data\" }");
string test= item["test"];
//test Result = "some data"
Try,
# cat test.sh
#!/bin/bash
/bin/touch file.txt
cron as:
* * * * * /bin/sh /home/myUser/scripts/test.sh
And you can confirm this by:
# tailf /var/log/cron
I think, the difference is in usage patterns.
I would prefer .on
over .click
because the former can use less memory and work for dynamically added elements.
Consider the following html:
<html>
<button id="add">Add new</button>
<div id="container">
<button class="alert">alert!</button>
</div>
</html>
where we add new buttons via
$("button#add").click(function() {
var html = "<button class='alert'>Alert!</button>";
$("button.alert:last").parent().append(html);
});
and want "Alert!" to show an alert. We can use either "click" or "on" for that.
click
$("button.alert").click(function() {
alert(1);
});
with the above, a separate handler gets created for every single element that matches the selector. That means
.on
$("div#container").on('click', 'button.alert', function() {
alert(1);
});
with the above, a single handler for all elements that match your selector, including the ones created dynamically.
.on
As Adrien commented below, another reason to use .on
is namespaced events.
If you add a handler with .on("click", handler)
you normally remove it with .off("click", handler)
which will remove that very handler. Obviously this works only if you have a reference to the function, so what if you don't ? You use namespaces:
$("#element").on("click.someNamespace", function() { console.log("anonymous!"); });
with unbinding via
$("#element").off("click.someNamespace");
If you have this:
<div class="a x">Foo</div>
<div class="b x">Bar</div>
<div class="c x">Baz</div>
And you only want to select the elements which have .x
and (.a
or .b
), you could write:
.x:not(.c) { ... }
but that's convenient only when you have three "sub-classes" and you want to select two of them.
Selecting only one sub-class (for instance .a
): .a.x
Selecting two sub-classes (for instance .a
and .b
): .x:not(.c)
Selecting all three sub-classes: .x

could you try doing JSON.stringify(obj);
Like this
var stringify = JSON.stringify(obj);
fs.writeFileSync('./data.json', stringify , 'utf-8');
If you're using data binding, then you need to use the ContentRendered event.
For the code below, the Header is NULL when the Loaded event is raised. However, Header gets its value when the ContentRendered event is raised.
<MenuItem Header="{Binding NewGame_Name}" Command="{Binding NewGameCommand}" />
In MySql, you can get 10 rows starting from row 20 using:

Location permission privacy change in Android 10 or Android Q.
We have to define additional ACCESS_BACKGROUND_LOCATION
permission if user wants to access their current location in background so user needs to granted permission runtime also in requestPermission()
If we are using lower than Android 10 device then ACCESS_BACKGROUND_LOCATION
permission allow automatically with ACCESS_FINE_LOCATION
or ACCESS_COARSE_LOCATION
permission
This tabular format might be easy to understand what if we don't specify ACCESS_BACKGROUND_LOCATION
in manifest file.

You can pipe grep
result to head
in conjunction with stdbuf.
Note, that in order to ensure stopping after Nth match, you need to using stdbuf
to make sure grep
don't buffer its output:
stdbuf -oL grep -rl 'pattern' * | head -n1
stdbuf -oL grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -n1
stdbuf -oL grep -nH -m 1 -R "django.conf.urls.defaults" * | head -n1
As soon as head
consumes 1 line, it terminated and grep
will receive SIGPIPE
because it still output something to pipe while head
was gone.
This assumed that no file names contain newline.
XCode does come with a simulator for the iPad and iPhone.

As the question indicates this applies to a migration in a development type environment that has not yet been released.
This issue can be solved in these steps: restore your database to the last good migration, delete the bad migration from your Entity Framework project, generate a new migration and apply it to the database. Note: Judging from the comments these exact commands may no longer be applicable if you are using EF Core.
Step 1: Restore to a previous migration
If you haven't yet applied your migration you can skip this part. To restore your database schema to a previous point issue the Update-Database command with -TargetMigration option specify the last good migration. If your entity framework code resides in a different project in your solution, you may need to use the '-Project' option or switch the default project in the package manager console.
Update-Database –TargetMigration: <name of last good migration>
To get the name of the last good migration use the 'Get-Migrations' command to retrieve a list of the migration names that have been applied to your database.
PM> Get-Migrations
Retrieving migrations that have been applied to the target database.
201508242303096_Bad_Migration
201508211842590_The_Migration_applied_before_it
201508211440252_And_another
This list shows the most recent applied migrations first. Pick the migration that occurs in the list after the one you want to downgrade to, ie the one applied before the one you want to downgrade. Now issue an Update-Database.
Update-Database –TargetMigration: "<the migration applied before it>"
All migrations applied after the one specified will be down-graded in order starting with the latest migration applied first.
Step 2: Delete your migration from the project
remove-migration name_of_bad_migration
If the remove-migration
command is not available in your version of Entity Framework, delete the files of the unwanted migration your EF project 'Migrations' folder manually. At this point, you are free to create a new migration and apply it to the database.
Step 3: Add your new migration
add-migration my_new_migration
Step 4: Apply your migration to the database
update-database
You first need to create a table in your database in which you will be importing the CSV file. After the table is created, follow the steps below.
• Log into your database using SQL Server Management Studio
• Right click on your database and select Tasks -> Import Data...
• Click the Next >
button
• For the Data Source, select Flat File Source
. Then use the Browse button to select the CSV file. Spend some time configuring how you want the data to be imported before clicking on the Next >
button.
• For the Destination, select the correct database provider (e.g. for SQL Server 2012, you can use SQL Server Native Client 11.0). Enter the Server name. Check the Use SQL Server Authentication
radio button. Enter the User name, Password, and Database before clicking on the Next >
button.
• On the Select Source Tables and Views window, you can Edit Mappings before clicking on the Next >
button.
• Check the Run immediately
check box and click on the Next >
button.
• Click on the Finish
button to run the package.
The above was found on this website (I have used it and tested):
document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';
Your container does not have a height.
Add height: 200px;
to the containers css and the kitty will stay inside.
None of the above worked for me, the only one working was
insert into tableName
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1
The nullif is used since it is not possible to pass null in the select statement otherwise.
Use sh, it'll make things a lot easier:
import sh
print sh.swfdump("/tmp/filename.swf", "-d")
Using AOP/AspectJ and @Loggable
annotation from jcabi-aspects you can do it easy and compact:
@Loggable(Loggable.DEBUG)
public String getSomeResult() {
// return some value
}
Every call to this method will be sent to SLF4J logging facility with DEBUG
logging level. And every log message will include execution time.
Great answers! I guess the answer to my question was "no" I was not missing some obvious solution. Here is the function I will use that condenses the good ideas expressed in the answers.
def int2base(x,b,alphabet='0123456789abcdefghijklmnopqrstuvwxyz'):
'convert an integer to its string representation in a given base'
if b<2 or b>len(alphabet):
if b==64: # assume base64 rather than raise error
alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
else:
raise AssertionError("int2base base out of range")
if isinstance(x,complex): # return a tuple
return ( int2base(x.real,b,alphabet) , int2base(x.imag,b,alphabet) )
if x<=0:
if x==0:
return alphabet[0]
else:
return '-' + int2base(-x,b,alphabet)
# else x is non-negative real
rets=''
while x>0:
x,idx = divmod(x,b)
rets = alphabet[idx] + rets
return rets
Running the following experiment the pythonic way:
[s + mystring for s in mylist]
seems to be ~35% faster than the obvious use of a for loop like this:
i = 0
for s in mylist:
mylist[i] = s+mystring
i = i + 1
Experiment
import random
import string
import time
mystring = '/test/'
l = []
ref_list = []
for i in xrange( 10**6 ):
ref_list.append( ''.join(random.choice(string.ascii_lowercase) for i in range(10)) )
for numOfElements in [5, 10, 15 ]:
l = ref_list*numOfElements
print 'Number of elements:', len(l)
l1 = list( l )
l2 = list( l )
# Method A
start_time = time.time()
l2 = [s + mystring for s in l2]
stop_time = time.time()
dt1 = stop_time - start_time
del l2
#~ print "Method A: %s seconds" % (dt1)
# Method B
start_time = time.time()
i = 0
for s in l1:
l1[i] = s+mystring
i = i + 1
stop_time = time.time()
dt0 = stop_time - start_time
del l1
del l
#~ print "Method B: %s seconds" % (dt0)
print 'Method A is %.1f%% faster than Method B' % ((1 - dt1/dt0)*100)
Results
Number of elements: 5000000
Method A is 38.4% faster than Method B
Number of elements: 10000000
Method A is 33.8% faster than Method B
Number of elements: 15000000
Method A is 35.5% faster than Method B

Use this convertor , It doesn't fail at all: Services_Json
// create a new instance of Services_JSON
$json = new Services_JSON();
// convert a complexe value to JSON notation, and send it to the browser
$value = array('foo', 'bar', array(1, 2, 'baz'), array(3, array(4)));
$output = $json->encode($value);
print($output);
// prints: ["foo","bar",[1,2,"baz"],[3,[4]]]
// accept incoming POST data, assumed to be in JSON notation
$input = file_get_contents('php://input', 1000000);
$value = $json->decode($input);
// if you want to convert json to php arrays:
$json = new Services_JSON(SERVICES_JSON_LOOSE_TYPE);
If you need to do this with the pathlib
module, you can use pathlib.Path.open()
to open the file and print the text from read()
:
from pathlib import Path
fpath = Path("somefile.txt")
with fpath.open() as f:
print(f.read())
Or simply call pathlib.Path.read_text()
:
from pathlib import Path
fpath = Path("somefile.txt")
print(fpath.read_text())
With Me I had the library ticked under Eclipse>Project Properties>Android what I just did was uncheck the ticked library.
To find a very long list of words in big files, it can be more efficient to use egrep:
remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B
Just add overflow:hidden
in the first div
style. That should be enough.
Try setting 'clientCredentialType' to 'Windows' instead of 'Ntlm'.
I think that this is what the server is expecting - i.e. when it says the server expects "Negotiate,NTLM", that actually means Windows Auth, where it will try to use Kerberos if available, or fall back to NTLM if not (hence the 'negotiate')
I'm basing this on somewhat reading between the lines of: Selecting a Credential Type
The method len() returns the number of elements in the list.
list1, list2 = [123, 'xyz', 'zara'], [456, 'abc']
print "First list length : ", len(list1)
print "Second list length : ", len(list2)
When we run above program, it produces the following result -
First list length : 3 Second list length : 2
%cd%
will give you the path of the directory from where the script is running.
Just run:
echo %cd%
If you're creating multiple maps in a loop, if a single map DOM element doesn't exist, it breaks all of them. First, check to make sure the DOM element exists before creating a new Map object.
[...]
for( var i = 0; i <= self.multiple_maps; i++ ) {
var map_element = document.getElementById( 'map' + '-' + i.toString() );
// Element doesn't exist, don't create map!
if( null === map_element ) {
continue;
}
var map = new google.maps.Map( map_element, myOptions);
}
[...]

My efforts in WSL have been unsuccessful.
For those running on Windows Subsystem for Linux (WSL) there seems to be an open issue at this time for missing core dump files.
The comments indicate that
This is a known issue that we are aware of, it is something we are investigating.
This is a development storage
part of Tomas M answer for Chrome. We must add listener
window.addEventListener("storage", (e)=> { console.log(e) } );
Load/save item in storage not runt this event - we MUST trigger it manually by
window.dispatchEvent( new Event('storage') ); // THIS IS IMPORTANT ON CHROME
and now, all open tab-s will receive event
If you need a CakePHP Docker Container with MySQL, I have created a Docker image for that purpose! No need to worry about setting it up. It just works!
Here's how I installed in Ubuntu-based image:
https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker/blob/master/Dockerfile#L8
RUN docker-php-ext-install mysql mysqli pdo pdo_mysql
Building and running your application is just a 2 step process (considering you are in the current directory of the app):
$ docker build -t myCakePhpApp .
$ docker run -ti myCakePhpApp
onmouseover="$('.play-detail').stop().animate({'height': '84px'},'300');"
onmouseout="$('.play-detail').stop().animate({'height': '44px'},'300');"
Just put two stops -- one onmouseover and one onmouseout.
i use php5.6
code:
$person = ["name"=>"mohammed", "age"=>30];
$person['addr'] = "Sudan";

You will have to pass a context
object to it. Either this
if you have a reference to the class in an activty, or getApplicationContext()
public class MyActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
RegularClass regularClass = new RegularClass(this);
}
}
Then you can use it in the constructor (or set it to an instance variable):
public class RegularClass(){
private Context context;
public RegularClass(Context current){
this.context = current;
}
public findResource(){
context.getResources().getXml(R.xml.samplexml);
}
}
Where the constructor accepts Context
as a parameter
Yes, you are using it incorrectly, Series.replace()
is not inplace operation by default, it returns the replaced dataframe/series, you need to assign it back to your dataFrame/Series for its effect to occur. Or if you need to do it inplace, you need to specify the inplace
keyword argument as True
Example -
data['sex'].replace(0, 'Female',inplace=True)
data['sex'].replace(1, 'Male',inplace=True)
Also, you can combine the above into a single replace
function call by using list
for both to_replace
argument as well as value
argument , Example -
data['sex'].replace([0,1],['Female','Male'],inplace=True)
Example/Demo -
In [10]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])
In [11]: data['sex'].replace([0,1],['Female','Male'],inplace=True)
In [12]: data
Out[12]:
sex split
0 Male 0
1 Female 1
2 Male 0
3 Female 1
You can also use a dictionary, Example -
In [15]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])
In [16]: data['sex'].replace({0:'Female',1:'Male'},inplace=True)
In [17]: data
Out[17]:
sex split
0 Male 0
1 Female 1
2 Male 0
3 Female 1
May be you are trying to attach a function when table rows are clicked.

==
does a numeric comparison: it converts both arguments to a number and then compares them. As long as $str1
and $str2
both evaluate to 0 as numbers, the condition will be satisfied.
eq
does a string comparison: the two arguments must match lexically (case-sensitive) for the condition to be satisfied.
"foo" == "bar"; # True, both strings evaluate to 0.
"foo" eq "bar"; # False, the strings are not equivalent.
"Foo" eq "foo"; # False, the F characters are different cases.
"foo" eq "foo"; # True, both strings match exactly.
The POST/GET with 204 seems fine in the first sight and will also work.
Documentation says, 2xx -- This class of status codes indicates the action requested by the client was received, understood, accepted, and processed successfully. whereas 4xx -- The 4xx class of status code is intended for situations in which the client seems to have erred.
Since, the request was successfully received, understood and processed on server. The result was that the resource was not found. So, in this case this was not an error on the client side or the client has not erred.
Hence this should be a series 2xx code and not 4xx. Sending 204 (No Content) in this case will be better than a 404 or 410 response.
in a windows form app, you can simply use Application.StartupPath
but for DLLs and console apps the code is much harder to remember...

w
for write
r+

It's a horrible thing to do, as everybody else has said, but if you really are intent on doing it, use this code, and put a load of returns at the top of the page's source:

document.onclick=function(event){
if (event.button == 2) {
alert('Right Click Message');
return false;
}
}
}

Since filter
returns a QuerySet
, you can use count to check how many results were returned. This is assuming you don't actually need the results.
num_results = User.objects.filter(email = cleaned_info['username']).count()
After looking at the documentation though, it's better to just call len on your filter if you are planning on using the results later, as you'll only be making one sql query:
A count() call performs a SELECT COUNT(*) behind the scenes, so you should always use count() rather than loading all of the record into Python objects and calling len() on the result (unless you need to load the objects into memory anyway, in which case len() will be faster).
num_results = len(user_object)
There's no way to use CSS for this purpose. My advice is to include a javascript code where you assign or change the css class applied to the inputs. Something like that :
function change_input() {_x000D_
$('#id_input1')_x000D_
.toggleClass('class_disabled')_x000D_
.toggleClass('class_enabled');_x000D_
_x000D_
$('.class_disabled').attr('disabled', '');_x000D_
$('.class_enabled').removeAttr('disabled', '');_x000D_
}
_x000D_
.class_disabled { background-color : #FF0000; }_x000D_
.class_enabled { background-color : #00FF00; }
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>_x000D_
<form> _x000D_
Input: <input id="id_input1" class="class_enabled" /> _x000D_
<input type="button" value="Toggle" onclick="change_input()";/> _x000D_
</form>
_x000D_
For future reference,
I have encountered the same problem -- pylab was not showing under ipython. The problem was fixed by changing ipython's config file {ipython_config.py}. In the config file
c.InteractiveShellApp.pylab = 'auto'
I changed 'auto' to 'qt' and now I see graphs
You might also consider adding "
.
For example for %i in (*.wav) do opusenc "%~ni.wav" "%~ni.opus"
is very good idea.
If d is a dictionary, then d.get(k, v)
means, give me the value of k in d, unless k isn't there, in which case give me v. It's being used here to get the current count of the character, which should start at 0 if the character hasn't been encountered before.
This topic is strongly related with the built-in bind
function and introduced in ECMAScript 6 Arrow Functions. It was really annoying, because for every new "class" (function actually) method we wanted to use, we had to bind
this in order to have access to the scope.
JavaScript by default doesn't set its scope of this
on functions (it doesn't set the context on this
). By default you have to explicitly say which context you want to have.
The arrow functions automatically gets so-called lexical scope (have access to variable's definition in its containing block). When using arrow functions it automatically binds this
to the place where the arrow function was defined in the first place, and the context of this arrow functions is its containing block.
See how it works in practice on the simplest examples below.
Before Arrow Functions (no lexical scope by default):
const programming = {
language: "JavaScript",
getLanguage: function() {
return this.language;
}
}
const globalScope = programming.getLanguage;
console.log(globalScope()); // Output: undefined
const localScope = programming.getLanguage.bind(programming);
console.log(localScope()); // Output: "JavaScript"
With arrow functions (lexical scope by default):
const programming = {
language: "JavaScript",
getLanguage: function() {
return this.language;
}
}
const arrowFunction = () => {
console.log(programming.getLanguage());
}
arrowFunction(); // Output: "JavaScript"
You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.
Also, remove the onclick="alert()"
from your submit. This is the cause for your first undefined
message.
<?php
$posted = false;
if( $_POST ) {
$posted = true;
// Database stuff here...
// $result = mysql_query( ... )
$result = $_POST['name'] == "danny"; // Dummy result
}
?>
<html>
<head></head>
<body>
<?php
if( $posted ) {
if( $result )
echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
else

How is this different from the following?
This line of code here:
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));
constructs a new String object (i.e. a copy of oldString
), while this line of code:
String newString = oldString;
declares a new variable of type java.lang.String
and initializes it to refer to the same String object as the variable oldString
.
Is there any scenario in which the two lines will have different outputs?
Absolutely:
String newString = oldString;
boolean isSameInstance = newString == oldString; // isSameInstance == true
vs.
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));
// isSameInstance == false (in most cases)
boolean isSameInstance = newString == oldString;
a_horse_with_no_name (see comment) is right of course. The equivalent of
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));
is
String newString = new String(oldString);
minus the subtle difference wrt the encoding that Peter Lawrey explains in his answer.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.
I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.
# Enable TCP/IP
Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable
# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433
# Modify TCP/IP properties to enable an IP address
$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }
# Restart SQL Server
Restart-Service 'MSSQL$SQLEXPRESS'
Well,
If you mark all involved classes as serializable you can :
public static List<T> CloneList<T>(List<T> oldList)
{
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream();
formatter.Serialize(stream, oldList);
stream.Position = 0;
return (List<T>)formatter.Deserialize(stream);
}
Source:
That's not possible. localhost
always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.
If you want to access it e.g. in a browser, connect to it using the local IP instead:
http://192.168.180.1:8000
This is just an example of course, you can find out the actual IP by issuing an ifconfig
command on a shell in the guest operating system.
It's really easy to specify your own decimal separator. Just took me about 2 hours to figure it out :D.
You see that you were using the current ou other culture that you specify right? Well, the only thing the parser needs is an IFormatProvider. If you give it the
CultureInfo.CurrentCulture.NumberFormat
as a formatter, it will format the double according to your current culture's NumberDecimalSeparator
. What I did was just to create a new instance of the NumberFormatInfo
class and set it's NumberDecimalSeparator
property to whichever separator string I wanted. Complete code below:
double value = 2.3d;
NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = "-";
string x = value.ToString(nfi);
The result? "2-3"
encodeURIComponent/decodeURIComponent() is almost always the pair you want to use, for concatenating together and splitting apart text strings in URI parts.
encodeURI in less common, and misleadingly named: it should really be called fixBrokenURI. It takes something that's nearly a URI, but has invalid characters such as spaces in it, and turns it into a real URI. It has a valid use in fixing up invalid URIs from user input, and it can also be used to turn an IRI (URI with bare Unicode characters in) into a plain URI (using %-escaped UTF-8 to encode the non-ASCII).
decodeURI decodes the same characters as decodeURIComponent except for a few special ones. It is provided to be an inverse of encodeURI, but you still can't count on it to return the same as you originally put in — see eg. decodeURI(encodeURI('%20 '));
.
Where encodeURI should really be named fixBrokenURI(), decodeURI() could equally be called potentiallyBreakMyPreviouslyWorkingURI(). I can think of no valid use for it anywhere; avoid.
Just for completeness (and this is not at all recommended):
int length;
try
{
length = str.getBytes("UTF-16BE").length / 2
}
catch (UnsupportedEncodingException e)
{
throw new AssertionError("Cannot happen: UTF-16BE is always a supported encoding");
}
This works because a char
is a UTF-16 code unit, and str.length()
returns the number of such code units. Each UTF-16 code unit takes up 2 bytes, so we divide by 2. Additionally, there is no byte order mark written with UTF-16BE.

if objFolderItem
is Nothing when you call
objFolder.GetDetailsOf(objFolderItem, i)
the string returned is the name of the property, rather than its (undefined) value
e.g. when i=3
it returns "Date modified"

For JDK 1.3 or earlier :
-Xnoagent -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006
For JDK 1.4
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006
For newer JDK :
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=6006
Please change the port number based on your needs.
From java technotes
From 5.0 onwards the -agentlib:jdwp option is used to load and specify options to the JDWP agent. For releases prior to 5.0, the -Xdebug and -Xrunjdwp options are used (the 5.0 implementation also supports the -Xdebug and -Xrunjdwp options but the newer -agentlib:jdwp option is preferable as the JDWP agent in 5.0 uses the JVM TI interface to the VM rather than the older JVMDI interface)
One more thing to note, from JVM Tool interface documentation:
JVM TI was introduced at JDK 5.0. JVM TI replaces the Java Virtual Machine Profiler Interface (JVMPI) and the Java Virtual Machine Debug Interface (JVMDI) which, as of JDK 6, are no longer provided.

The output looks correct to me:
Invalid JavaScript code: sun.org.mozilla.javascript.internal.EvaluatorException: missing } after property list (<Unknown source>) in <Unknown source>; at line number 1
I think Invalid Javascript code: ..
is the start of the exception message.
Normally the stacktrace isn't returned with the message:
try {
throw new RuntimeException("hu?\ntrace-line1\ntrace-line2");
} catch (Exception e) {
System.out.println(e.getMessage()); // prints "hu?"
}
So maybe the code you are calling catches an exception and rethrows a ScriptException
. In this case maybe e.getCause().getMessage()
can help you.
It is to mark the parameter as optional.
One instance where it is almost necessary to call GC.Collect() is when automating Microsoft Office through Interop. COM objects for Office don't like to automatically release and can result in the instances of the Office product taking up very large amounts of memory. I'm not sure if this is an issue or by design. There's lots of posts about this topic around the internet so I won't go into too much detail.
When programming using Interop, every single COM object should be manually released, usually though the use of Marshal.ReleseComObject(). In addition, calling Garbage Collection manually can help "clean up" a bit. Calling the following code when you're done with Interop objects seems to help quite a bit:
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
In my personal experience, using a combination of ReleaseComObject and manually calling garbage collection greatly reduces the memory usage of Office products, specifically Excel.
You can use java.util.regex.Pattern with the CASE_INSENSITIVE flag for case insensitive matching:
Pattern.compile(Pattern.quote(strptrn), Pattern.CASE_INSENSITIVE).matcher(str1).find();

In NodeJS if you know the ID
, the looping through the array is very slow compared to object[ID]
.
const uniqueString = require('unique-string');
const obj = {};
const arr = [];
var seeking;
//create data
for(var i=0;i<1000000;i++){
var getUnique = `${uniqueString()}`;
if(i===888555) seeking = getUnique;
arr.push(getUnique);
obj[getUnique] = true;
}
//retrieve item from array
console.time('arrTimer');
for(var x=0;x<arr.length;x++){
if(arr[x]===seeking){
console.log('Array result:');
console.timeEnd('arrTimer');
break;
}
}
//retrieve item from object
console.time('objTimer');
var hasKey = !!obj[seeking];
console.log('Object result:');
console.timeEnd('objTimer');
And the results:
Array result:
arrTimer: 12.857ms
Object result:
objTimer: 0.051ms
Even if the seeking ID is the first one in the array/object:
Array result:
arrTimer: 2.975ms
Object result:
objTimer: 0.068ms

I think you probably want to use a token list for this purpose:
to set up the token list

to assign the name:

It took me more than 4 hours to fix this problem. I followed the guide from http://docs.phonegap.com/en/2.1.0/guide_getting-started_android_index.md.html#Getting%20Started%20with%20Android
I'm using Android Studio (Eclipse with ADT could not work properly because of the build problem).
Solution that worked for me:
I put the /assets/www/index.html under app/src/main/assets directory. (take care AndroidStudio has different perspectives like Project or Android)
use super.loadUrl("file:///android_asset/www/index.html"); instead of super.loadUrl("file:///android_assets/www/index.html"); (no s)

You will get something like this
LocalDate.parse(
"23-Mar-2017" ,
DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US )
)
The Question and other Answers are now outdated, using troublesome old date-time classes that are now legacy, supplanted by the java.time classes.
You seem to be dealing with date-only values. So do not use a date-time class. Instead use LocalDate
. The LocalDate
class represents a date-only value without time-of-day and without time zone.
Specify a Locale
to determine (a) the human language for translation of name of day, name of month, and such, and (b) the cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.
Parse a string.
String input = "23-Mar-2017" ;
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US ) ;
LocalDate ld = LocalDate.parse( input , f );
Generate a string.
String output = ld.format( f );
If you were given numbers rather than text for the year, month, and day-of-month, use LocalDate.of
.
LocalDate ld = LocalDate.of( 2017 , 3 , 23 ); // ( year , month 1-12 , day-of-month )
See this code run live at IdeOne.com.
input: 23-Mar-2017
ld.toString(): 2017-03-23
output: 23-Mar-2017
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Using a JDBC driver compliant with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings nor java.sql.* classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
The following sample looks recursively for your search string
in the *.xml
and *.js
files located somewhere inside the folders path1
, path2
and path3
.
grep -r --include=*.xml --include=*.js "your search string" path1 path2 path3
So you can search in a subset of the files for many directories, just providing the paths at the end.
select previous, Present, previous-Present as Difference from tablename

In here:
if (ValidationUtils.isNullOrEmpty(lastName)) {
registrationErrors.add(ValidationErrors.LAST_NAME);
}
if (!ValidationUtils.isEmailValid(email)) {
registrationErrors.add(ValidationErrors.EMAIL);
}
you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do
if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
registrationErrors.add(ValidationErrors.EMAIL);
}
or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.
Hopefully this is helpful to anyone coming looking for a universal/isomorphic solution, since the checksum issue is what led me here in the first place.
As said above, I've created a simple utility to sequentially create a new id. Since the IDs keep incrementing on the server, and start over from 0 in the client, I decided to reset the increment each the SSR starts.
// utility to generate ids
let current = 0
export default function generateId (prefix) {
return `${prefix || 'id'}-${current++}`
}
export function resetIdCounter () { current = 0 }
And then in the root component's constructor or componentWillMount, call the reset. This essentially resets the JS scope for the server in each server render. In the client it doesn't (and shouldn't) have any effect.
This answer is not the direct answer for the question. But it should help you figure out which solution fits best for your problem.
When analysing the problem you should activate the debug option -vv
Then rsync will output which files are included or excluded by which pattern:
building file list ...
[sender] hiding file FILE1 because of pattern FILE1*
[sender] showing file FILE2 because of pattern *
For me I was using expired auth keys. Generated new ones and boom.
Objective-C is a more perfect superset of C. In C and Objective-C implicit casting from void*
to a struct pointer is allowed.
Foo* bar = malloc(sizeof(Foo));
C++ will not compile unless the void
pointer is explicitly cast:
Foo* bar = (Foo*)malloc(sizeof(Foo));
The relevance of this to every day programming is zero, just a fun trivia fact.
AFAIK you can simply use
iVal = rs.getInt("ID_PARENT");
if (rs.wasNull()) {
// do somthing interesting to handle this situation
}
even if it is NULL.
In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that +
returned a non-const value, and you could write:
(a + b).expensive();
In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.
In summary, there is a rationale for this practice, but it is essentially obsolete.
I came across this question, but in order to make it work for my case (using dragover on a DOM-element (not being canvas in my case)), I found that you only have have to use offsetX
and offsetY
on the dragover-mouse event.
onDragOver(event){
var x = event.offsetX;
var y = event.offsetY;
}
I solved my problem using entire address where my code is: Before:
if(!exists("foo", mode="function")) source("utils.r")
After:
if(!exists("foo", mode="function")) source("C:/tests/utils.r")
I had the exact same problem when manually compiling through the command line, my solution was I didn't include the -sourcepath directory so that way all the subdirectory java files would be compiled too!
Why parentheses?
Here is the quote from the book programming in scala.
Another important idea illustrated by this example will give you insight into why arrays are accessed with parentheses in Scala. Scala has fewer special cases than Java. Arrays are simply instances of classes like any other class in Scala. When you apply parentheses surrounding one or more values to a variable, Scala will transform the code into an invocation of a method named apply on that variable. So greetStrings(i) gets transformed into greetStrings.apply(i). Thus accessing an element of an array in Scala is simply a method call like any other. This principle is not restricted to arrays: any application of an object to some arguments in parentheses will be transformed to an apply method call. Of course this will compile only if that type of object actually defines an apply method. So it's not a special case; it's a general rule.
Here are a few examples how to pull certain element (first elem in this case) using functional programming style.
// Create a multdimension Array
scala> val a = Array.ofDim[String](2, 3)
a: Array[Array[String]] = Array(Array(null, null, null), Array(null, null, null))
scala> a(0) = Array("1","2","3")
scala> a(1) = Array("4", "5", "6")
scala> a
Array[Array[String]] = Array(Array(1, 2, 3), Array(4, 5, 6))
// 1. paratheses
scala> a.map(_(0))
Array[String] = Array(1, 4)
// 2. apply
scala> a.map(_.apply(0))
Array[String] = Array(1, 4)
// 3. function literal
scala> a.map(a => a(0))
Array[String] = Array(1, 4)
// 4. lift
scala> a.map(_.lift(0))
Array[Option[String]] = Array(Some(1), Some(4))
// 5. head or last
scala> a.map(_.head)
Array[String] = Array(1, 4)
Regarding the PHP comment 'No, PHP wouldn't like it'. Actually, PHP would keep on chugging unless you set some very restrictive (for PHP) exception/error levels, (and maybe not even then).
What WILL happen by default is that an access to a non existing variable/out of bounds array element 'unsets' your value that you're assigning to. NO, that is NOT null. PHP has a Perl/C lineage, from what I understand. So there are: unset and non existing variables, values which ARE set but are NULL, Boolean False values, then everything else that standard langauges have. You have to test for those separately, OR choose the RIGHT evaluation built in function/syntax.
This is a short asynchronous function to use without requiring third party libs
Array.prototype.each = function (iterator, callback) {
var iterate = function () {
pointer++;
if (pointer >= this.length) {
callback();
return;
}
iterator.call(iterator, this[pointer], iterate, pointer);
}.bind(this),
pointer = -1;
iterate(this);
};
This is indeed rather odd.
If aSourceDictionary
were a dictionary, I don't believe it is possible for your code to fail in the manner you describe.
This leads to two hypotheses:
The code you're actually running is not identical to the code in your question (perhaps an earlier or later version?)
aSourceDictionary
is in fact not a dictionary, but is some other structure (for example, a list).
An orthodox way to achieve it, is by defining a new function:
public static String join(String joinStr, String... strings) {
if (strings == null || strings.length == 0) {
return "";
} else if (strings.length == 1) {
return strings[0];
} else {
StringBuilder sb = new StringBuilder(strings.length * 1 + strings[0].length());
sb.append(strings[0]);
for (int i = 1; i < strings.length; i++) {
sb.append(joinStr).append(strings[i]);
}
return sb.toString();
}
}
Sample:
String[] array = new String[] { "7, 7, 7", "Bill", "Bob", "Steve",
"[Bill]", "1,2,3", "Apple ][","~,~" };
String joined;
joined = join(" and ","7, 7, 7", "Bill", "Bob", "Steve", "[Bill]", "1,2,3", "Apple ][","~,~");
joined = join(" and ", array); // same result
System.out.println(joined);
Output:
7, 7, 7 and Bill and Bob and Steve and [Bill] and 1,2,3 and Apple ][ and ~,~
Making a small adjustment to Tor Valamo's solution to fix the problem noticed by Dominic Rodger, you could use:
// Remove anything which isn't a word, whitespace, number
// or any of the following caracters -_~,;[]().
// If you don't need to handle multi-byte characters
// you can use preg_replace rather than mb_ereg_replace
// Thanks @Lukasz Rysiak!
$file = mb_ereg_replace("([^\w\s\d\-_~,;\[\]\(\).])", '', $file);
// Remove any runs of periods (thanks falstro!)
$file = mb_ereg_replace("([\.]{2,})", '', $file);
Removing ./
from source path should resolve your issue:
COPY test.json /home/test.json
COPY test.py /home/test.py
My solution is a mix of several answers here.
I checked the build server, and Windows7/NET4.0 SDK was already installed, so I did find the path:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets`
However, on this line:
<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" />
$(MSBuildExtensionsPath) expands to C:\Program Files\MSBuild which does not have the path.
Therefore what I did was to create a symlink, using this command:
mklink /J "C:\Program Files\MSBuild\Microsoft\VisualStudio" "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio"
This way the $(MSBuildExtensionsPath) expands to a valid path, and no changes are needed in the app itself, only in the build server (perhaps one could create the symlink every build, to make sure this step is not lost and is "documented").
Percent encoding. Replace the hash with %23

Javascript is pretty good at manipulating css.
document.body.style.cursor = *cursor-url*;
//OR
var elementToChange = document.getElementsByTagName("body")[0];
elementToChange.style.cursor = "url('cursor url with protocol'), auto";
or with jquery:
$("html").css("cursor: url('cursor url with protocol'), auto");
Firefox will not work unless you specify a default cursor after the imaged one!
Also remember that IE6 only supports .cur and .ani cursors.
If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:
// in plain js
document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
// in jquery
$('#parentOfElementToBeRedrawn').hide().show(0);

I had an issue with connected repository. What's how I fixed:
I deleted manually .git folder under my project folder, run git init and then it all worked.
your build classpath is correct, which is why you can compile. the classpath for your JUnit needs to be checked. go to the Run menu and choose 'open run dialog.' in there you should see a tree on the left with JUnit as an option. open that node and find and select your test. on the right pane you will see a tab for classpath. take a look to ensure that your class that the test is trying to instantiate would be found.
edit:
this seems to be an issue with maven and its behavior after a release changed the default Eclipse output folders. i have seen solutions described where
mvn clean test
does the trick or with the first three, there were reports of the issue recurring. the last looks best to me, but if it doesnt work, please try the others.
Here's a method if you want to do it for just one specific file:
RewriteRule ^about$ about.php [L]
Ref: http://css-tricks.com/snippets/htaccess/remove-file-extention-from-urls/
<script type="text/javascript">
jQuery(document).ready(function($) {
var url = window.location.pathname,
urlRegExp = new RegExp(url.replace(/\/$/,'') + "$");
$("#navbar li a").each(function() {//alert('dsfgsdgfd');
if(urlRegExp.test(this.href.replace(/\/$/,''))){
$(this).addClass("active");}
});
});
</script>
You can fix NullReferenceException in a clean way using Null-conditional Operators in c#6 and write less code to handle null checks.
It's used to test for null before performing a member access (?.) or index (?[) operation.
Example
var name = p?.Spouse?.FirstName;
is equivalent to:
if (p != null)
{
if (p.Spouse != null)
{
name = p.Spouse.FirstName;
}
}
The result is that the name will be null when p is null or when p.Spouse is null.
Otherwise, the variable name will be assigned the value of the p.Spouse.FirstName.

I usually use SchemaSpy to do this, but recently I found a really simple article on sqlfairy that just uses the dump file to create the structure graph
I was struggling from this for a while, tried almost all the solutions here but could not get rid of debugging info in TF 1.14
, I have tried following multiple solutions:
import os
import logging
import sys
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' # FATAL
stderr = sys.stderr
sys.stderr = open(os.devnull, 'w')
import tensorflow as tf
tf.get_logger().setLevel(tf.compat.v1.logging.FATAL)
tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.ERROR)
logging.getLogger('tensorflow').setLevel(tf.compat.v1.logging.FATAL)
sys.stderr = stderr
import absl.logging
logging.root.removeHandler(absl.logging._absl_handler)
absl.logging._warn_preinit_stderr = False
The debugging info still showed up, what finally helped was restarting my pc (actually restarting the kernel should work). So if somebody has similar problem, try restart kernel after you set your environment vars, simple but might not come in mind.
you can use AlertDialog
as ProgressDialog
refer below code for the ProgressDialog
. This function you need to call whenever you show a progress dialog.
Code:
public void setProgressDialog() {
int llPadding = 30;
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setPadding(llPadding, llPadding, llPadding, llPadding);
ll.setGravity(Gravity.CENTER);
LinearLayout.LayoutParams llParam = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
llParam.gravity = Gravity.CENTER;
ll.setLayoutParams(llParam);
ProgressBar progressBar = new ProgressBar(this);
progressBar.setIndeterminate(true);
progressBar.setPadding(0, 0, llPadding, 0);
progressBar.setLayoutParams(llParam);
llParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
llParam.gravity = Gravity.CENTER;
TextView tvText = new TextView(this);
tvText.setText("Loading ...");
tvText.setTextColor(Color.parseColor("#000000"));
tvText.setTextSize(20);
tvText.setLayoutParams(llParam);
ll.addView(progressBar);
ll.addView(tvText);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true);
builder.setView(ll);
AlertDialog dialog = builder.create();
dialog.show();
Window window = dialog.getWindow();
if (window != null) {
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.copyFrom(dialog.getWindow().getAttributes());
layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT;
layoutParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
dialog.getWindow().setAttributes(layoutParams);
}
}
Output:
try this code
Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(photo, CAMERA_PIC_REQUEST);
This works in all browsers:
window.location.href = '...';
If you wanted to change the page without it reflecting in the browser back history, you can do:
window.location.replace('...');
Another solution which works in Python 2 and 3:
#foo.py
import sys
class Foo(object):
pass
def print_classes():
current_module = sys.modules[__name__]
for key in dir(current_module):
if isinstance( getattr(current_module, key), type ):
print(key)
# test.py
import foo
foo.print_classes()
I faced the error "TypeError: 'NoneType' object is not callable " but for a different issue. With the above clues, i was able to debug and got it right! The issue that i faced was : I had the custome Library written and my file wasnt recognizing it although i had mentioned it
example:
Library ../../../libraries/customlibraries/ExtendedWaitKeywords.py
the keywords from my custom library were recognized and that error was resolved only after specifying the complete path, as it was not getting the callable function.
array = array.uniq
uniq
removes all duplicate elements and retains all unique elements in the array.
This is one of many beauties of the Ruby language.
Not for entire application or particular class.
CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture
at all.
Sample code to change cultures for current thread:
CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;
For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:
(3.3).ToString(new CultureInfo("fr-FR"))
Let's take an example:
TABLE NAME=EMPLOYEE
And I want to change the column EMPLOYEE_NAME
to NOT NULL
. This query can be used for the task:
ALTER TABLE EMPLOYEE MODIFY EMPLOYEE.EMPLOYEE_NAME datatype NOT NULL;
Same thing you can implement in Python-
import requests,json
def get_media_id(media_url):
url = 'https://api.instagram.com/oembed/?callback=&url=' + media_url
response = requests.get(url).json()
print(response['media_id'])
get_media_id('MEDIA_URL')
You can find NLTK version simply by doing:
In [1]: import nltk
In [2]: nltk.__version__
Out[2]: '3.2.5'
And similarly for scikit-learn,
In [3]: import sklearn
In [4]: sklearn.__version__
Out[4]: '0.19.0'
I'm using python3 here.
from https://git-scm.com/book/en/v2/Git-Tools-Advanced-Merging
This will basically do a fake merge. It will record a new merge commit with both branches as parents, but it will not even look at the branch you’re merging in. It will simply record as the result of the merge the exact code in your current branch.
$ git merge -s ours mundo
Merge made by the 'ours' strategy.
$ git diff HEAD HEAD~
You can see that there is no difference between the branch we were on and the result of the merge.
This can often be useful to basically trick Git into thinking that a branch is already merged when doing a merge later on. For example, say you branched off a release branch and have done some work on it that you will want to merge back into your master branch at some point. In the meantime some bugfix on master needs to be backported into your release branch. You can merge the bugfix branch into the release branch and also merge -s ours the same branch into your master branch (even though the fix is already there) so when you later merge the release branch again, there are no conflicts from the bugfix.
A situation I've found to be useful if I want master to reflect the changes of a new topic branch. I've noticed that -Xtheirs doesn't merge without conflicts in some circumstances... e.g.
$ git merge -Xtheirs topicFoo
CONFLICT (modify/delete): js/search.js deleted in HEAD and modified in topicFoo. Version topicFoo of js/search.js left in tree.
In this case the solution I found was
$ git checkout topicFoo
from topicFoo, first merge in master using the -s ours strategy, this will create the fake commit that is just the state of topicFoo. $ git merge -s ours master
check the created merge commit
$ git log
now checkout the master branch
$ git checkout master
merge the topic branch back but this time use the -Xtheirs recursive strategy, this will now present you with a master branch with the state of topicFoo.
$ git merge -X theirs topicFoo
There's a couple of other tricks that Postgres offers for string matching (if that happens to be your DB):
ILIKE, which is a case insensitive LIKE match:
select * from people where name ilike 'JOHN'
Matches:
And if you want to get really mad you can use regular expressions:
select * from people where name ~ 'John.*'
Matches:
I tried all the above with v 1.8.13 to no avail.
What worked for me (on macOS) was to use the doxywizard->Expert tag to fill the USE_MD_FILE_AS_MAINPAGE
setting.
It made the following changes to my Doxyfile:
USE_MDFILE_AS_MAINPAGE = ../README.md
...
INPUT = ../README.md \
../sdk/include \
../sdk/src
Note the line termination for INPUT
, I had just been using space as a separator as specified in the documentation. AFAICT this is the only change between the not-working and working version of the Doxyfile.
Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.
A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt
and jshint
.
These lines add more meaning
Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.
Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:
There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.
Please Note that grunt plugin is also an npm package.
Question-1
When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json
It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.
Question-2
When should I ever install packages explicitly like that without adding them to the file that manages dependencies
It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request
, then you have two options:
OR
npm install --save request
--save
options adds the dependency to package.json file as well. If you don't specify --save
option, it will only download the package but the json file will be unaffected.
You can do this either way, there will not be a substantial difference.
Which SQL was not specified, SQL 2005 / 2008
SELECT yourfields from yourTable WHERE yourfieldWithDate > dateadd(dd,-1,getdate())
If you are on the 2008 increased accuracy date types, then use the new sysdatetime() function instead, equally if using UTC times internally swap to the UTC calls.
This Code works well for me calling oracle stored procedure
Add references by right clicking on your project name in solution explorer >Add Reference >.Net then Add namespaces.
using System.Data.OracleClient;
using System.Data;
then paste this code in event Handler
string str = "User ID=username;Password=password;Data Source=Test";
OracleConnection conn = new OracleConnection(str);
OracleCommand cmd = new OracleCommand("stored_procedure_name", conn);
cmd.CommandType = CommandType.StoredProcedure;
--Ad parameter list--
cmd.Parameters.Add("parameter_name", "varchar2").Value = value;
....
conn.Open();
cmd.ExecuteNonQuery();
And its Done...Happy Coding with C#
instanceof
is used to check if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.
If you put "\n" in a string in the xml file, it's taken as "\\n"
So , I did :
text = text.Replace("\\\n", "\n"); ( text is taken from resX file)
And then I get a line jump on the screen
Instanceof is very fast. It boils down to a bytecode that is used for class reference comparison. Try a few million instanceofs in a loop and see for yourself.
You can use
#pragma GCC push_options
#pragma GCC optimize ("O0")
your code
#pragma GCC pop_options
to disable optimizations since GCC 4.4.
See the GCC documentation if you need more details.
Since already there are many answers for the question but none of them shows the breakdown of Inversion Control term I see an opportunity to give a more concise and useful answer.
Inversion of Control is a pattern that implements the Dependency Inversion Principle (DIP). DIP states the following: 1. High-level modules should not depend on low-level modules. Both should depend on abstractions (e.g. interfaces). 2. Abstractions should not depend on details. Details (concrete implementations) should depend on abstractions.
There are three types of Inversion of Control:
Interface Inversion Providers shouldn’t define an interface. Instead, the consumer should define the interface and providers must implement it. Interface Inversion allows eliminating the necessity to modify the consumer each time when a new provider added.
Flow Inversion Changes control of the flow. For example, you have a console application where you asked to enter many parameters and after each entered parameter you are forced to press Enter. You can apply Flow Inversion here and implement a desktop application where the user can choose the sequence of parameters’ entering, the user can edit parameters, and at the final step, the user needs to press Enter only once.
Creation Inversion It can be implemented by the following patterns: Factory Pattern, Service Locator, and Dependency Injection. Creation Inversion helps to eliminate dependencies between types moving the process of dependency objects creation outside of the type that uses these dependency objects. Why dependencies are bad? Here are a couple of examples: direct creation of a new object in your code makes testing harder; it is impossible to change references in assemblies without recompilation (OCP principle violation); you can’t easily replace a desktop-UI by a web-UI.
You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file
.
Instead of
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);
Use
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);
Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.
try this , it works 100 % : add columns and rows programatically : you need to create item class at first :
public class Item
{
public int Num { get; set; }
public string Start { get; set; }
public string Finich { get; set; }
}
private void generate_columns()
{
DataGridTextColumn c1 = new DataGridTextColumn();
c1.Header = "Num";
c1.Binding = new Binding("Num");
c1.Width = 110;
dataGrid1.Columns.Add(c1);
DataGridTextColumn c2 = new DataGridTextColumn();
c2.Header = "Start";
c2.Width = 110;
c2.Binding = new Binding("Start");
dataGrid1.Columns.Add(c2);
DataGridTextColumn c3 = new DataGridTextColumn();
c3.Header = "Finich";
c3.Width = 110;
c3.Binding = new Binding("Finich");
dataGrid1.Columns.Add(c3);
dataGrid1.Items.Add(new Item() { Num = 1, Start = "2012, 8, 15", Finich = "2012, 9, 15" });
dataGrid1.Items.Add(new Item() { Num = 2, Start = "2012, 12, 15", Finich = "2013, 2, 1" });
dataGrid1.Items.Add(new Item() { Num = 3, Start = "2012, 8, 1", Finich = "2012, 11, 15" });
}
The npm view <pkg> version
prints the last version by release date. That might very well be an hotfix release for a older stable branch at times.
The solution is to list all versions and fetch the last one by version number
$ npm view <pkg> versions --json | jq -r '.[-1]'
Or with awk instead of jq:
$ npm view <pkg> --json | awk '/"$/{print gensub("[ \"]", "", "G")}'
There is nothing bad or better, It just depends on the precedence of operators. Since ||
has higher precedence than or
, so ||
is mostly used.

To speed up this procedure, make sure you don't use SELECT *
, but only select what you really need. Use SELECT *
only during development when you try to find out what you need to use, because then the query will take much longer to complete.

Here the defination of Rendersection from MSDN
In layout pages, renders the content of a named section.MSDN
In _layout.cs page put
@RenderSection("Bottom",false)
Here render the content of bootom section and specifies false
boolean property to specify whether the section is required or not.
@section Bottom{
This message form bottom.
}
That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.
Two or three ways (depends what you want), say we are at Current Date is (in tsql code) -
DECLARE @myCurrentDate datetime = '11Apr2014 10:02:25 AM'
(BTW - did you mean 11April2014 or 04Nov2014 in your original post? hard to tell, as datetime is culture biased. In Israel 11/04/2015 means 11April2014. I know in the USA 11/04/2014 it means 04Nov2014. tommatoes tomatos I guess)
SELECT @myCurrentDate + 360
- by default datetime calculations followed by + (some integer), just add that in days. So you would get 2015-04-06 10:02:25.000
- not exactly what you wanted, but rather just a ball park figure for a close date next year.
SELECT DateADD(DAY, 365, @myCurrentDate)
or DateADD(dd, 365, @myCurrentDate)
will give you '2015-04-11 10:02:25.000'. These two are syntatic sugar (exacly the same). This is what you wanted, I should think. But it's still wrong, because if the date was a "3 out of 4" year (say DECLARE @myCurrentDate datetime = '11Apr2011 10:02:25 AM'
) you would get '2012-04-10 10:02:25.000'. because 2012 had 366 days, remember? (29Feb2012 consumes an "extra" day. Almost every fourth year has 29Feb).
So what I think you meant was
SELECT DateADD(year, 1, @myCurrentDate)
which gives 2015-04-11 10:02:25.000
.
or better yet
SELECT DateADD(year, 1, DateADD(day, DateDiff(day, 0, @myCurrentDate), 0))
which gives you 2015-04-11 00:00:00.000
(because datetime also has time, right?). Subtle, ah?
Change the window name in your two different calls:
function popitup(url,windowName) {
newwindow=window.open(url,windowName,'height=200,width=150');
if (window.focus) {newwindow.focus()}
return false;
}
windowName must be unique when you open a new window with same url otherwise the same window will be refreshed.
Unfortunately, no approached mentioned here worked for me. I have to register couple PFX in a docker container and I need to pass the password via command line.
So I re-developed the
sn.exe -i <infile> <container>
command in C# using the RSACryptoServiceProvider. The source and the app are on GitHub in
the SnInstallPfx project.
The SnInstallPfx app accepts a PFX key and its password. It computes the key container name (VS_KEY_*) automatically (borrowed from MSBuild source code) and installs it to the strong name CSP.
Usage:
SnInstallPfx.exe <pfx_infile> <pfx_password>
// or pass a container name if the default is not what you need (e.g. C++)
SnInstallPfx.exe <pfx_infile> <pfx_password> <container_name>
With .Net WebRequest:
public static string GetPublicIP()
{
string url = "http://checkip.dyndns.org";
System.Net.WebRequest req = System.Net.WebRequest.Create(url);
System.Net.WebResponse resp = req.GetResponse();
System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream());
string response = sr.ReadToEnd().Trim();
string[] a = response.Split(':');
string a2 = a[1].Substring(1);
string[] a3 = a2.Split('<');
string a4 = a3[0];
return a4;
}
Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.
The configuration and the access to the Connection string looks all right to me. I would always add a providername
<connectionStrings>
<add name="Dbconnection"
connectionString="Server=localhost; Database=OnlineShopping;
Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
Value for network.proxy.http_port
should be integer (no quotes should be used) and network.proxy.type
should be set as 1 (ProxyType.MANUAL
, Manual proxy settings)
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.type", 1);
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", 3128);
WebDriver driver = new FirefoxDriver(profile);
I had this requirement recently and used other posts from this question to create this script:

Probably way too late but this is another option:
$('body').popover({
selector: '[rel=popover]',
trigger: 'hover',
html: true,
content: function () {
return $(this).parents('.row').first().find('.metaContainer').html();
}
});
It works far better this way (preserving responsiveness):
<!-- somewhere deep start -->
<div class="row">
<div class="center-block col-md-4" style="float: none; background-color: grey">
Hi there!
</div>
</div>
<!-- somewhere deep end -->
Use a non-consuming regular expression.
The typical (i.e. Perl/Java) notation is:
(?=
expr)
This means "match expr but after that continue matching at the original match-point."
You can do as many of these as you want, and this will be an "and." Example:
(?=match this expression)(?=match this too)(?=oh, and this)
You can even add capture groups inside the non-consuming expressions if you need to save some of the data therein.
The ^M is typically caused by the Windows operator newlines, and translated onto Unix looks like a ^M. The command dos2unix should remove them nicely
dos2unix [options] [-c convmode] [-o file ...] [-n infile outfile ...]
You can do this with far less code:
function callPlayer(func, args) {
var i = 0,
iframes = document.getElementsByTagName('iframe'),
src = '';
for (i = 0; i < iframes.length; i += 1) {
src = iframes[i].getAttribute('src');
if (src && src.indexOf('youtube.com/embed') !== -1) {
iframes[i].contentWindow.postMessage(JSON.stringify({
'event': 'command',
'func': func,
'args': args || []
}), '*');
}
}
}
Working example: http://jsfiddle.net/kmturley/g6P5H/296/
Swift 5
Swift 5: Check using canOpneURL
if valid then it's open.
guard let url = URL(string: "https://iosdevcenters.blogspot.com/") else {
return
}
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
Transform the sets into arrays, flatten them and finally the constructor will uniqify.
const union = (...sets) => new Set(sets.map(s => [...s]).flat());
You can use the DATE(Year;Month;Day) to make operations on date:
Examples:
=DATE(2013;3;8 + 30) give the result... 7 april 2013 !
=DATE(2013;3 + 15; 8) give the result... 8 june 2014 !
It's very surprising but it works...
Try this How to move a full Git repository
Create a local repository in the temp-dir directory using:
git clone temp-dir
Go into the temp-dir directory.
To see a list of the different branches in ORI do:
git branch -a
Checkout all the branches that you want to copy from ORI to NEW using:
git checkout branch-name
Now fetch all the tags from ORI using:
git fetch --tags
Before doing the next step make sure to check your local tags and branches using the following commands:
git tag
git branch -a
Now clear the link to the ORI repository with the following command:
git remote rm origin
Now link your local repository to your newly created NEW repository using the following command:
git remote add origin <url to NEW repo>
Now push all your branches and tags with these commands:
git push origin --all
git push --tags
You now have a full copy from your ORI repo.

df['A'] = df['A'].apply(str)
Convert the whole frame
In [21]: df.applymap(str)
Out[21]:
A B
0 0 1
1 2 3
2 4 5
3 6 7
4 8 9
In [22]: df.applymap(str).iloc[0,0]
Out[22]: '0'
df = df.applymap(str)
I found simple way, it using shift()
function waitReq(id)
{
jQuery.ajax(
{
type: 'POST',
url: ajaxurl,
data:
{
"page": id
},
success: function(resp)
{
...........
// check array length if not "0" continue to use next array value
if(ids.length)
{
waitReq(ids.shift()); // 2
)
},
error: function(resp)
{
....................
if(ids.length)
{
waitReq(ids.shift());
)
}
});
}
var ids = [1, 2, 3, 4, 5];
// shift() = delete first array value (then print)
waitReq(ids.shift()); // print 1

select *
from
(
( select * from TableInSchema1
minus
select * from TableInSchema2)
union all
( select * from TableInSchema2
minus
select * from TableInSchema1)
)
should do the trick if you want to solve this with a query
You're missing a required space between the bracket and -e
:
#!/bin/bash
if [ -e x.txt ]
then
echo "ok"
else
echo "nok"
fi
It's just more convenient to reason about in many cases.
Basically, we could think of a range as an interval between start
and end
. If start <= end
, the length of the interval between them is end - start
. If len
was actually defined as the length, you'd have:
len(range(start, end)) == start - end
However, we count the integers included in the range instead of measuring the length of the interval. To keep the above property true, we should include one of the endpoints and exclude the other.
Adding the step
parameter is like introducing a unit of length. In that case, you'd expect
len(range(start, end, step)) == (start - end) / step
for length. To get the count, you just use integer division.
I see in your code that you are trying to pass an ARRAY to POST action. In that case follow below working code -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
function submitForm() {
var roles = ["role1", "role2", "role3"];
jQuery.ajax({
type: "POST",
url: "@Url.Action("AddUser")",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(roles),
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});
}
</script>
<input type="button" value="Click" onclick="submitForm()"/>
And the controller action is going to be -
public ActionResult AddUser(List<String> Roles)
{
return null;
}
Then when you click on the button -
This didn't exist when the question was asked, but ES2015 introduced array destructuring, allowing you to write it as follows:
let a = 1, b = 2;
// a: 1, b: 2
[a, b] = [b, a];
// a: 2, b: 1
I'm using a little helper method:
public static int QueryString(string paramName, int defaultValue)
{
int value;
if (!int.TryParse(Request.QueryString[paramName], out value))
return defaultValue;
return value;
}
This method allows me to read values from the query string in the following way:
int id = QueryString("id", 0);
Here is simple solution..
<tr style='cursor: pointer; cursor: hand;' onclick="window.location='google.com';"></tr>
if you want to route to another page
this.$router.push({path: '/pagename'})
if you want to route with params
this.$router.push({path: '/pagename', param: {param1: 'value1', param2: value2})
This will be helpful for the right bottom rounded button
HTML :
<a class="fixedButton" href>
<div class="roundedFixedBtn"><i class="fa fa-phone"></i></div>
</a>
CSS:
.fixedButton{
position: fixed;
bottom: 0px;
right: 0px;
padding: 20px;
}
.roundedFixedBtn{
height: 60px;
line-height: 80px;
width: 60px;
font-size: 2em;
font-weight: bold;
border-radius: 50%;
background-color: #4CAF50;
color: white;
text-align: center;
cursor: pointer;
}
