Programs & Examples On #Keyboard events

I am not very good with this but KeyboardEvent => see KeyboardEvent is initialized with initKeyEvent .
Here is an example for emitting event on <input type="text" /> element

document.getElementById("txbox").addEventListener("keypress", function(e) {_x000D_
  alert("Event " + e.type + " emitted!\nKey / Char Code: " + e.keyCode + " / " + e.charCode);_x000D_
}, false);_x000D_
_x000D_
document.getElementById("btn").addEventListener("click", function(e) {_x000D_
  var doc = document.getElementById("txbox");_x000D_
  var kEvent = document.createEvent("KeyboardEvent");_x000D_
  kEvent.initKeyEvent("keypress", true, true, null, false, false, false, false, 74, 74);_x000D_
  doc.dispatchEvent(kEvent);_x000D_
}, false);

<input id="txbox" type="text" value="" />_x000D_
<input id="btn" type="button" value="CLICK TO EMIT KEYPRESS ON TEXTBOX" />

user648852's idea at least for me works great for OS X, here is the code to do it:

#!/usr/bin/env python

import time
from Quartz.CoreGraphics import CGEventCreateKeyboardEvent
from Quartz.CoreGraphics import CGEventPost

# Python releases things automatically, using CFRelease will result in a scary error
#from Quartz.CoreGraphics import CFRelease

I am not sure if intercepting function keys is possible, but I would avoid using function keys all together. Function keys are used by browsers to perform a variety of tasks, some of them quite common. For example, in Firefox on Linux, at least six or seven of the function keys are reserved for use by the browser:

• F1 (Help),
• F3 (Search),
• F5 (Refresh),
• F6 (focus address bar),
• F7 (caret browsing mode),
• F11 (full screen mode), and
• F12 (used by several add-ons, including Firebug)

The worst part is that different browsers on different operating systems use different keys for different things. That's a lot of differences to account for. You should stick to safer, less commonly used key combinations.

That's shorter.

Use this class in your layout :

public class ActionEditText extends EditText
{
    public ActionEditText(Context context)
    {
        super(context);
    }

    public ActionEditText(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public ActionEditText(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
    }

    @Override
    public InputConnection onCreateInputConnection(EditorInfo outAttrs)
    {
        InputConnection conn = super.onCreateInputConnection(outAttrs);
        outAttrs.imeOptions &= ~EditorInfo.IME_FLAG_NO_ENTER_ACTION;
        return conn;
    }

}

In xml:

<com.test.custom.ActionEditText
                android:id="@+id/postED"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:background="@android:color/transparent"
                android:gravity="top|left"
                android:hint="@string/msg_type_message_here"
                android:imeOptions="actionSend"
                android:inputType="textMultiLine"
                android:maxLines="5"
                android:padding="5dip"
                android:scrollbarAlwaysDrawVerticalTrack="true"
                android:textColor="@color/white"
                android:textSize="20sp" />

To produce key events without Windows Forms Context, We can use the following method,

[DllImport("user32.dll")]
public static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, uint dwExtraInfo);

sample code is given below:

const int VK_UP = 0x26; //up key
const int VK_DOWN = 0x28;  //down key
const int VK_LEFT = 0x25;
const int VK_RIGHT = 0x27;
const uint KEYEVENTF_KEYUP = 0x0002;
const uint KEYEVENTF_EXTENDEDKEY = 0x0001;
int press()
{
    //Press the key
    keybd_event((byte)VK_UP, 0, KEYEVENTF_EXTENDEDKEY | 0, 0);
    return 0;
}

List of Virtual Keys are defined here.

A minor extension of Andrea's answer above makes the helper method more useful when you may also want to capture modified enter presses (i.e. ctrl-enter or shift-enter). For example, this variant allows binding like:

$('textarea').enterKey(function() {$(this).closest('form').submit(); }, 'ctrl')

to submit a form when the user presses ctrl-enter with focus on that form's textarea.

$.fn.enterKey = function (fnc, mod) {
    return this.each(function () {
        $(this).keypress(function (ev) {
            var keycode = (ev.keyCode ? ev.keyCode : ev.which);
            if ((keycode == '13' || keycode == '10') && (!mod || ev[mod + 'Key'])) {
                fnc.call(this, ev);
            }
        })
    })
}

There is all you need:

expected bytes, not str

The leading b makes your string binary.

What version of Python do you use? 2.x or 3.x?

Edit: See http://docs.python.org/release/3.0.1/whatsnew/3.0.html#text-vs-data-instead-of-unicode-vs-8-bit for the gory details of strings in Python 3.x

AFAIK you must reformat your String in ISO format to be able to cast it as a Date:

cast(concat(substr(STR_DMY,7,4), '-',
            substr(STR_DMY,1,2), '-',
            substr(STR_DMY,4,2)
           )
     as date
     ) as DT

To display a Date as a String with specific format, then it's the other way around, unless you have Hive 1.2+ and can use date_format()

=> did you check the documentation by the way?

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

If you simply want to check for permissions (rather than request for permissions), I wrote a simple extension like so:

fun BaseActivity.checkPermission(permissionName: String): Boolean {
        return if (Build.VERSION.SDK_INT >= 23) {
            val granted =
                ContextCompat.checkSelfPermission(this, permissionName)
            granted == PackageManager.PERMISSION_GRANTED
        } else {
            val granted =
                PermissionChecker.checkSelfPermission(this, permissionName)
            granted == PermissionChecker.PERMISSION_GRANTED
        }
    }

Now, if I want to check for a permission I can simply pass in a permission like so:

checkPermission(Manifest.permission.READ_CONTACTS)

For UTF-16, the character needs four bytes (two code units) if it starts with 0xD800 or greater; such a character is called a "surrogate pair." More specifically, a surrogate pair has the form:

[0xD800 - 0xDBFF]  [0xDC00 - 0xDFF]

where [...] indicates a two-byte code unit with the given range. Anything <= 0xD7FF is one code unit (two bytes). Anything >= 0xE000 is invalid (except BOM markers, arguably).

See http://unicodebook.readthedocs.io/unicode_encodings.html, section 7.5.

Sending email can be done with Intents which will require no configuration. But then it will require user interaction and the layout will be a bit restricted.

Build and sending a more complex email without user interaction entails building your own client. The first thing is that the Sun Java API for email are unavailable. I have had success leveraging the Apache Mime4j library to build email. All based on the docs at nilvec.

CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.

Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.

I just experienced the same problem using the virtual environment. For me installing the package using python from the venv worked:
.\venv\environment\Scripts\python.exe -m pip install flask-sqlalchemy

document.getElementById('table1').rows[0].cells.length

cells is not a property of a table, rows are. Cells is a property of a row though

You could follow these steps to revert the incorrect commit(s) or to reset your remote branch back to correct HEAD/state.

1. checkout the remote branch to local repo.
   git checkout development

2. copy the commit hash (i.e. id of the commit immediately before the wrong commit) from git log git log -n5

   output:
   

   commit 7cd42475d6f95f5896b6f02e902efab0b70e8038 "Merge branch 'wrong-commit' into 'development'"
   commit f9a734f8f44b0b37ccea769b9a2fd774c0f0c012 "this is a wrong commit"
   commit 3779ab50e72908da92d2cfcd72256d7a09f446ba "this is the correct commit"

3. reset the branch to the commit hash copied in the previous step
   git reset <commit-hash> (i.e. 3779ab50e72908da92d2cfcd72256d7a09f446ba)

4. run the git status to show all the changes that were part of the wrong commit.
5. simply run git reset --hard to revert all those changes.
6. force-push your local branch to remote and notice that your commit history is clean as it was before it got polluted.
   git push -f origin development

The syntax you have there for your function doesn't make sense (why would the return value have a member called arr?).

To find the index, use std::distance and std::find from the <algorithm> header.

int x = std::distance(arr, std::find(arr, arr + 5, 3));

Or you can make it into a more generic function:

template <typename Iter>
size_t index_of(Iter first, Iter last, typename const std::iterator_traits<Iter>::value_type& x)
{
    size_t i = 0;
    while (first != last && *first != x)
      ++first, ++i;
    return i;
}

Here, I'm returning the length of the sequence if the value is not found (which is consistent with the way the STL algorithms return the last iterator). Depending on your taste, you may wish to use some other form of failure reporting.

In your case, you would use it like so:

size_t x = index_of(arr, arr + 5, 3);

Try what's below. It will help you...

You will have to use some sort of network sniffer if you want to get at this sort of data and you're likely to run into the same problem (pulling out the relevant data from the overall network traffic) with those that you do now with Wireshark.

Install file loader first:

$ npm install file-loader --save-dev

And add this rule in webpack.config.js

           {
                test: /\.(png|jpg|gif)$/,
                use: [{
                    loader: 'file-loader',
                    options: {}
                }]

React Native TextInput provides keyboardType props with following possible values : default number-pad decimal-pad numeric email-address phone-pad

so for your case you can use keyboardType='number-pad' for accepting only numbers. This doesn't include '.'

so,

<TextInput 
  style={styles.textInput}
  keyboardType = 'number-pad'
  onChangeText = {(text)=> this.onChanged(text)}
  value = {this.state.myNumber}
/>

is what you have to use in your case.

for more details please refer the official doc link for TextInput : https://facebook.github.io/react-native/docs/textinput#keyboardtype

Suppose we have a file as Message.cpp or a .c file

Steps 1: Preprocessing (Argument -E )

g++ -E .\Message.cpp > P1

P1 file generated has expanded macros and header file contents and comments are stripped off.

Step 2: Translate Preprocessed file to assembly (Argument -S). This task is done by compiler

g++ -S .\Message.cpp

An assembler (ASM) is generated (Message.s). It has all the assembly code.

Step 3: Translate assembly code to Object code. Note: Message.s was generated in Step2. g++ -c .\Message.s

An Object file with the name Message.o is generated. It is the binary form.

Step 4: Linking the object file. This task is done by linker

g++ .\Message.o -o MessageApp

An exe file MessageApp.exe is generated here.

#include <iostream>
using namespace std;

 //This a sample program
  int main()
{
cout << "Hello" << endl;
 cout << PQR(P,K) ;
getchar();
return 0;
}

The following is slower than the approaches timed here, but we can compute the extra column based on the contents of more than one column, and more than two values can be computed for the extra column.

Simple example using just the "Set" column:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Example with more colours and more columns taken into account:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    elif row["Type"] == "C":
        return "blue"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C   blue

Edit (21/06/2019): Using plydata

It is also possible to use plydata to do this kind of things (this seems even slower than using assign and apply, though).

from plydata import define, if_else

Simple if_else:

df = define(df, color=if_else('Set=="Z"', '"red"', '"green"'))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Nested if_else:

df = define(df, color=if_else(
    'Set=="Z"',
    '"red"',
    if_else('Type=="C"', '"green"', '"blue"')))

print(df)                            

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B   blue
3   Y    C  green

Unless you're worried about performance, use string streams:

#include <sstream>
//..

std::ostringstream ss;
ss << myFloat;
std::string s(ss.str());

If you're okay with Boost, lexical_cast<> is a convenient alternative:

std::string s = boost::lexical_cast<std::string>(myFloat);

Efficient alternatives are e.g. FastFormat or simply the C-style functions.

In my use case we had a similar need for CI CD. We used git flow with develop and master branches. Developers are free to merge their changes directly to develop or via a pull request from a feature branch. However to master we merge only the stable commits from the develop branch in an automated way via Jenkins.

In this case doing cherry-pick is not a good option. However we create a local-branch from the commit-id then merge that local-branch to master and perform mvn clean verify(we use maven). If success then release production version artifact to nexus using maven release plugin with localCheckout=true option and pushChanges=false. Finally when everything is success then push the changes and tag to origin.

A sample code snippet:

Assuming you are on master if done manually. However on jenkins, when you checkout the repo you will be on the default branch(master if configured).

git pull  // Just to pull any changes.
git branch local-<commitd-id> <commit-id>  // Create a branch from the given commit-id
git merge local-<commit-id>  // Merge that local branch to master.
mvn clean verify   // Verify if the code is build able
mvn <any args> release:clean release:prepare release:perform // Release artifacts
git push origin/master  // Push the local changes performed above to origin.
git push origin <tag>  // Push the tag to origin

This will give you a full control with a fearless merge or conflict hell.

Feel free to advise in case there is any better option.

Since I haven't found the correct instructions for doing this in Fedora (EDIT: people pointed in comments that this should also work on CentOS and Suse) (/etc/default/docker isn't used there), I'm adding my answer here:

You have to edit /etc/sysconfig/docker, and add the -g option in the OPTIONS variable. If there's more than one option, make sure you enclose them in "". In my case, that file contained:

OPTIONS=--selinux-enabled

so it would become

OPTIONS="--selinux-enabled -g /mnt"

After a restart (systemctl restart docker) , Docker should use the new directory

More simply you can utilize DropBox for this. The steps basically remain the same. You can do the following-:

1) upload your .ipa to dropBox, Share the link for this .ipa

2) Paste the shared link for .ipa in your manifest.plist file , Upload manifest file in DropBox again share the link for this .plist file

3)paste the link for this Plist in your index.html file with a suitable tag.

Share this index.html file with anybody who can tap on the URL and download. or you can directly hit the URL instead.

If none of the TargetDir or other macros point to the right place, use the ".." directory to go backwards up the folder hierarchy.

ie. Use $(SolutionDir)\..\.. to get your base directory.

For list of all macros, see here:

http://msdn.microsoft.com/en-us/library/c02as0cs.aspx

You can use it in a more compact way as:

var tifs = {1: 'Joe', 2: 'Jane'};
...

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { Object.entries(tifs).map((t,k) => <option key={k} value={t[0]}>{t[1]}</option>) }          
   </select>
)

And another slightly different flavour:

 Object.entries(tifs).map(([key,value],i) => <option key={i} value={key}>{value}</option>)  

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

MonoDevelop, the IDE associated with Mono Project should be enough for C# development on Linux. Now I don't know any good profilers and other tools for C# development on Linux. But then again mind you, that C# is a language more native to windows. You are better developing C# apps for windows than for linux.

EDIT: When you download MonoDevelop from the Ubuntu Software Center, it will contain pretty much everything you need to get started right away (Compiler, Runtime Environment, IDE). If you would like more information, see the following links:

If you want it to be dynamic, so that the value of the variable at the time of the click is used, do the following:

<script language="javascript" type="text/javascript">
var scrt_var = 10; 
</script>
<a href="2.html" onclick="location.href=this.href+'?key='+scrt_var;return false;">Link</a>

Of course, that's the quick and dirty solution. You should really have a script that after DOM load adds an onclick handler to all relevant <a> elements.

IntelliJ IDEA Plugins / GenerateSerialVersionUID https://plugins.jetbrains.com/plugin/?idea&id=185

very nice, very easy to install. you can install that from plugins menu, select install from disk, select the jar file you unpacked in the lib folder. restart, control + ins, and it pops up to generate serial UID from menu. love it. :-)

This is partly based on this earlier answer above by @A Boschman. In that solution, I found that the input size of the image greatly affected the ability of makeImageSpan() to properly center-align the image. Additionally, I found that the solution affected text spacing by creating unnecessary line spacing.

I found BaseImageSpan (from Facebook's Fresco library) to do the job particularly well:

 /**
 * Create an ImageSpan for the given icon drawable. This also sets the image size. Works best
 * with a square icon because of the sizing
 *
 * @param context       The Android Context.
 * @param drawableResId A drawable resource Id.
 * @param size          The desired size (i.e. width and height) of the image icon in pixels.
 *                      Use the lineHeight of the TextView to make the image inline with the
 *                      surrounding text.
 * @return An ImageSpan, aligned with the bottom of the text.
 */
private static BetterImageSpan makeImageSpan(Context context, int drawableResId, int size) {
    final Drawable drawable = context.getResources().getDrawable(drawableResId);
    drawable.mutate();
    drawable.setBounds(0, 0, size, size);
    return new BetterImageSpan(drawable, BetterImageSpan.ALIGN_CENTER);
}

Then supply your betterImageSpan instance to spannable.setSpan() as usual

If you want to select a value based on true / false use

[selected]="opt.selected == true"

 <option *ngFor="let opt of question.options" [value]="opt.key" [selected]="opt.selected == true">{{opt.selected+opt.value}}</option>

Angular 2 - Setting selected value on dropdown list

Instead of requiring explicit imports, the Swift compiler implicitly searches for .swiftmodule files of dependency Swift libraries.

Xcode can build swift modules for you, or refer to the railsware blog for command line instructions for swiftc.

Neither is terribly efficient since both methods have to calculate the string length or scan it each time. Instead, since you calculate the strlen()s of the individual strings anyway, put them in variables and then just strncpy() twice.

There's a workaround to achieve it.

1. First, bind your iframe to a target page with relative url. The browsers will treat the site in iframe the same domain with your website.

2. In your web server, using a rewrite module to redirect request from the relative url to absolute url. If you use IIS, I recommend you check on IIRF module.

BehaviorSubject vs Observable : RxJS has observers and observables, Rxjs offers a multiple classes to use with data streams, and one of them is a BehaviorSubject.

Observables : Observables are lazy collections of multiple values over time.

BehaviorSubject:A Subject that requires an initial value and emits its current value to new subscribers.

 // RxJS v6+
import { BehaviorSubject } from 'rxjs';

const subject = new BehaviorSubject(123);

//two new subscribers will get initial value => output: 123, 123
subject.subscribe(console.log);
subject.subscribe(console.log);

//two subscribers will get new value => output: 456, 456
subject.next(456);

//new subscriber will get latest value (456) => output: 456
subject.subscribe(console.log);

//all three subscribers will get new value => output: 789, 789, 789
subject.next(789);

// output: 123, 123, 456, 456, 456, 789, 789, 789

You can run something like this:

sqlcmd -S MyServer -d myDB -E -Q "select col1, col2, col3 from SomeTable" 
       -o "MyData.csv" -h-1 -s"," -w 700

• -h-1 removes column name headers from the result
  
• -s"," sets the column seperator to ,
  
• -w 700 sets the row width to 700 chars (this will need to be as wide as the longest row or it will wrap to the next line)

You cannot call a function that requires arguments in a template. Write a template tag or filter instead.

The immediate problem is you have is with quoting: by using double quotes ("..."), your variable references are instantly expanded, which is probably not what you want.

Use single quotes instead - strings inside single quotes are not expanded or interpreted in any way by the shell.

(If you want selective expansion inside a string - i.e., expand some variable references, but not others - do use double quotes, but prefix the $ of references you do not want expanded with \; e.g., \$var).

However, you're better off using a single here-doc[ument], which allows you to create multi-line stdin input on the spot, bracketed by two instances of a self-chosen delimiter, the opening one prefixed by <<, and the closing one on a line by itself - starting at the very first column; search for Here Documents in man bash or at http://www.gnu.org/software/bash/manual/html_node/Redirections.html.

If you quote the here-doc delimiter (EOF in the code below), variable references are also not expanded. As @chepner points out, you're free to choose the method of quoting in this case: enclose the delimiter in single quotes or double quotes, or even simply arbitrarily escape one character in the delimiter with \:

echo "creating new script file."

cat <<'EOF'  > "$servfile"
#!/bin/bash
read -p "Please enter a service: " ser
servicetest=`getsebool -a | grep ${ser}` 
if [ $servicetest > /dev/null ]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi
EOF

As @BruceK notes, you can prefix your here-doc delimiter with - (applied to this example: <<-"EOF") in order to have leading tabs stripped, allowing for indentation that makes the actual content of the here-doc easier to discern. Note, however, that this only works with actual tab characters, not leading spaces.

Employing this technique combined with the afterthoughts regarding the script's content below, we get (again, note that actual tab chars. must be used to lead each here-doc content line for them to get stripped):

cat <<-'EOF' > "$servfile"
    #!/bin/bash
    read -p "Please enter a service name: " ser
    if [[ -n $(getsebool -a | grep "${ser}") ]]; then 
      echo "We are now going to work with ${ser}."
    else
      exit 1
    fi
EOF

Finally, note that in bash even normal single- or double-quoted strings can span multiple lines, but you won't get the benefits of tab-stripping or line-block scoping, as everything inside the quotes becomes part of the string.

Thus, note how in the following #!/bin/bash has to follow the opening ' immediately in order to become the first line of output:

echo '#!/bin/bash
read -p "Please enter a service: " ser
servicetest=$(getsebool -a | grep "${ser}")
if [[ -n $servicetest ]]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi' > "$servfile"

Afterthoughts regarding the contents of your script:

• The syntax $(...) is preferred over `...` for command substitution nowadays.
• You should double-quote ${ser} in the grep command, as the command will likely break if the value contains embedded spaces (alternatively, make sure that the valued read contains no spaces or other shell metacharacters).
• Use [[ -n $servicetest ]] to test whether $servicetest is empty (or perform the command substitution directly inside the conditional) - [[ ... ]] - the preferred form in bash - protects you from breaking the conditional if the $servicetest happens to have embedded spaces; there's NEVER a need to suppress stdout output inside a conditional (whether [ ... ] or [[ ... ]], as no stdout output is passed through; thus, the > /dev/null is redundant (that said, with a command substitution inside a conditional, stderr output IS passed through).

Lets say each code is a function and its already written then the following can be used to iter through your coding list and exit the for-loop when a function is executed without error using the "break".

def a(): code a
def b(): code b
def c(): code c
def d(): code d

for func in [a, b, c, d]:  # change list order to change execution order.
   try:
       func()
       break
   except Exception as err:
       print (err)
       continue

I used "Exception " here so you can see any error printed. Turn-off the print if you know what to expect and you're not caring (e.g. in case the code returns two or three list items (i,j = msg.split('.')).

Using the following 1 line command for changing many files name in linux using phrase specificity:

find -type f -name '*.jpg' | rename 's/holiday/honeymoon/'

For all files with the extension ".jpg", if they contain the string "holiday", replace it with "honeymoon". For instance, this command would rename the file "ourholiday001.jpg" to "ourhoneymoon001.jpg".

This example also illustrates how to use the find command to send a list of files (-type f) with the extension .jpg (-name '*.jpg') to rename via a pipe (|). rename then reads its file list from standard input.

I wrote a powershell script to do it.

The advantage is that it prints out a summary of deleted folders, and ignored ones if you specified any subfolder hierarchy to be ignored.

This can happen if disableContentCompression() is set on a pooling manager assigned to your HttpClient, and the target server is trying to use gzip compression.

I had similar problem while installing SQL Server 2005 on Windows 7 Professional and got error SQL server failed to start. I logged in as a Administrator (my user id is administrator) in windows.

SOLUTION

1. Go to services, from control panel -> Administrative Tools

2. Click on properties of "SQL Server (MSSQLSERVER)"

3. Go to Log On Tab, Select "This Account"

4. Enter your windows login detail (administrator and password)

5. Start the service manually, it should work fine..

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

Having a table like this (with a header and a body)

<table id="myTableId">
    <thead>
    </thead>
    <tbody>
   </tbody>
</table>

remove every tr having a parent called tbody inside the #tableId

$('#tableId tbody > tr').remove();

and in reverse if you want to add to your table

$('#tableId tbody').append("<tr><td></td>....</tr>");

This is an equivalent solution to Tim Pietzcker's answer (see also comments of same answer):

^(?!.*filename\.js$).*\.js$

It means, match *.js except *filename.js.

To get to this solution, you can check which patterns the negative lookbehind excludes, and then exclude exactly these patterns with a negative lookahead.

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

Yes. You need to close the resultset, the statement and the connection. If the connection has come from a pool, closing it actually sends it back to the pool for reuse.

You typically have to do this in a finally{} block, such that if an exception is thrown, you still get the chance to close this.

Many frameworks will look after this resource allocation/deallocation issue for you. e.g. Spring's JdbcTemplate. Apache DbUtils has methods to look after closing the resultset/statement/connection whether null or not (and catching exceptions upon closing), which may also help.

I'll try to provide a comprehensive answer here. Much of the points appear in other answers, but I found each answer incomplete, and some incorrect.

First and foremost, objectForKey: is an NSDictionary method, while valueForKey: is a KVC protocol method required of any KVC complaint class - including NSDictionary.

Furthermore, as @dreamlax wrote, documentation hints that NSDictionary implements its valueForKey: method USING its objectForKey: implementation. In other words - [NSDictionary valueForKey:] calls on [NSDictionary objectForKey:].

This implies, that valueForKey: can never be faster than objectForKey: (on the same input key) although thorough testing I've done imply about 5% to 15% difference, over billions of random access to a huge NSDictionary. In normal situations - the difference is negligible.

Next: KVC protocol only works with NSString * keys, hence valueForKey: will only accept an NSString * (or subclass) as key, whilst NSDictionary can work with other kinds of objects as keys - so that the "lower level" objectForKey: accepts any copy-able (NSCopying protocol compliant) object as key.

Last, NSDictionary's implementation of valueForKey: deviates from the standard behavior defined in KVC's documentation, and will NOT emit a NSUnknownKeyException for a key it can't find - unless this is a "special" key - one that begins with '@' - which usually means an "aggregation" function key (e.g. @"@sum, @"@avg"). Instead, it will simply return a nil when a key is not found in the NSDictionary - behaving the same as objectForKey:

Following is some test code to demonstrate and prove my notes.

- (void) dictionaryAccess {
    NSLog(@"Value for Z:%@", [@{@"X":@(10), @"Y":@(20)} valueForKey:@"Z"]); // prints "Value for Z:(null)"

    uint32_t testItemsCount = 1000000;
    // create huge dictionary of numbers
    NSMutableDictionary *d = [NSMutableDictionary dictionaryWithCapacity:testItemsCount];
    for (long i=0; i<testItemsCount; ++i) {
        // make new random key value pair:
        NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
        NSNumber *value = @(arc4random_uniform(testItemsCount));
        [d setObject:value forKey:key];
    }
    // create huge set of random keys for testing.
    NSMutableArray *keys = [NSMutableArray arrayWithCapacity:testItemsCount];
    for (long i=0; i<testItemsCount; ++i) {
        NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
        [keys addObject:key];
    }

    NSDictionary *dict = [d copy];
    NSTimeInterval vtotal = 0.0, ototal = 0.0;

    NSDate *start;
    NSTimeInterval elapsed;

    for (int i = 0; i<10; i++) {

        start = [NSDate date];
        for (NSString *key in keys) {
            id value = [dict valueForKey:key];
        }
        elapsed = [[NSDate date] timeIntervalSinceDate:start];
        vtotal+=elapsed;
        NSLog (@"reading %lu values off dictionary via valueForKey took: %10.4f seconds", keys.count, elapsed);

        start = [NSDate date];
        for (NSString *key in keys) {
            id obj = [dict objectForKey:key];
        }
        elapsed = [[NSDate date] timeIntervalSinceDate:start];
        ototal+=elapsed;
        NSLog (@"reading %lu objects off dictionary via objectForKey took: %10.4f seconds", keys.count, elapsed);
    }

    NSString *slower = (vtotal > ototal) ? @"valueForKey" : @"objectForKey";
    NSString *faster = (vtotal > ototal) ? @"objectForKey" : @"valueForKey";
    NSLog (@"%@ takes %3.1f percent longer then %@", slower, 100.0 * ABS(vtotal-ototal) / MAX(ototal,vtotal), faster);
}

I suppose you're probably using the Decimal() objects from the decimal module? (If you need exactly two digits of precision beyond the decimal point with arbitrarily large numbers, you definitely should be, and that's what your question's title suggests...)

If so, the Decimal FAQ section of the docs has a question/answer pair which may be useful for you:

Q. In a fixed-point application with two decimal places, some inputs have many places and need to be rounded. Others are not supposed to have excess digits and need to be validated. What methods should be used?

A. The quantize() method rounds to a fixed number of decimal places. If the Inexact trap is set, it is also useful for validation:

>>> TWOPLACES = Decimal(10) ** -2       # same as Decimal('0.01')
>>> # Round to two places
>>> Decimal('3.214').quantize(TWOPLACES)
Decimal('3.21')
>>> # Validate that a number does not exceed two places
>>> Decimal('3.21').quantize(TWOPLACES, context=Context(traps=[Inexact]))
Decimal('3.21')
>>> Decimal('3.214').quantize(TWOPLACES, context=Context(traps=[Inexact]))
Traceback (most recent call last):
   ...
Inexact: None

The next question reads

Q. Once I have valid two place inputs, how do I maintain that invariant throughout an application?

If you need the answer to that (along with lots of other useful information), see the aforementioned section of the docs. Also, if you keep your Decimals with two digits of precision beyond the decimal point (meaning as much precision as is necessary to keep all digits to the left of the decimal point and two to the right of it and no more...), then converting them to strings with str will work fine:

str(Decimal('10'))
# -> '10'
str(Decimal('10.00'))
# -> '10.00'
str(Decimal('10.000'))
# -> '10.000'

for k, v in mydict.iteritems():
    if v is None:
        mydict[k] = ''

In a more general case, e.g. if you were adding or removing keys, it might not be safe to change the structure of the container you're looping on -- so using items to loop on an independent list copy thereof might be prudent -- but assigning a different value at a given existing index does not incur any problem, so, in Python 2.any, it's better to use iteritems.

In Python3 however the code gives AttributeError: 'dict' object has no attribute 'iteritems' error. Use items() instead of iteritems() here.

Refer to this post.

I had the same issue connecting to a remote machine. but I managed to login as below:

You can get your Button1 location and than increase the Y value every time you click on it.

Public Class Form1
    Dim BtnCoordinate As Point
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim btn As Button = New Button
        BtnCoordinate.Y += Button1.Location.Y + 4
        With btn
            .Location = New Point(BtnCoordinate)
            .Text = TextBox1.Text
            .ForeColor = Color.Black
        End With
        Me.Controls.Add(btn)
        Me.StartPosition = FormStartPosition.CenterScreen
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Button1Coordinate = Button1.Location
    End Sub
End Class

You should be able to match it with: /<primaryAddress>(.+?)<\/primaryAddress>/

The content between the tags will be in the matched group.

There's not a way as of 11/2012, HOWEVER

Highlight Text (In visual Studio.net)

ctrl + k + c, ctrl + k + u

Will comment / uncomment, respectively

And in swift, you don't need to import "QuartzCore/QuartzCore.h"

Just use:

button.layer.borderWidth = 0.8
button.layer.borderColor = (UIColor( red: 0.5, green: 0.5, blue:0, alpha: 1.0 )).cgColor

or

button.layer.borderWidth = 0.8
button.layer.borderColor = UIColor.grayColor().cgColor

As recommended by official documentation, you can use AsyncTask to handle work items shorter than 5ms in duration. If your task take more time, lookout for other alternatives.

HandlerThread is one alternative to Thread or AsyncTask. If you need to update UI from HandlerThread, post a message on UI Thread Looper and UI Thread Handler can handle UI updates.

Example code:

Android: Toast in a thread

There are several ways to do an email from HTML. Typically you see people doing a mailto like so:

<a href="mailto:[email protected]">Click to email</a>

But if you are doing it from a button you may want to look into a javascript solution.

Here is the cool regex style for digit grouping:

thenumber.toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1.");

There's a 3 ways to access the scope inside of the 'setTimeout' function

First,

const self = this
setTimeout(function() {
  self.setState({position:1})
}, 3000)

Second is to use ES6 arrow function, cause arrow function didn't have itself scope(this)

setTimeout(()=> {
   this.setState({position:1})
}, 3000)

Third one is to bind the scope inside of the function

setTimeout(function(){
   this.setState({position:1})
}.bind(this), 3000)

.then(() => new Promise((resolve) => setTimeout(resolve, 15000)))

UPDATE:

when I need sleep in async function I throw in

await new Promise(resolve => setTimeout(resolve, 1000))

If you need to find values for variables other than those standard VS macros, you could do that easily using Process Explorer. Start it, find the process your Visual Studio instance runs in, right click, Properties ? Environment. It lists all those $ vars as key-value pairs:

First, create staticfiles folder. Inside that folder create css, js, and img folder.

settings.py

import os

PROJECT_DIR = os.path.dirname(__file__)

DATABASES = {
    'default': {
         'ENGINE': 'django.db.backends.sqlite3', 
         'NAME': os.path.join(PROJECT_DIR, 'myweblabdev.sqlite'),                        
         'USER': '',
         'PASSWORD': '',
         'HOST': '',                      
         'PORT': '',                     
    }
}

MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')

STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(PROJECT_DIR, 'staticfiles'),
)

main urls.py

from django.conf.urls import patterns, include, url
from django.conf.urls.static import static

from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from myweblab import settings

admin.autodiscover()

urlpatterns = patterns('',
    .......
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns += staticfiles_urlpatterns()

Most terse version I can think of

Len(Trim(TextBox1.Value)) = 0

If you need to do this multiple times, wrap it in a function

Public Function HasContent(text_box as Object) as Boolean
    HasContent = (Len(Trim(text_box.Value)) > 0)
End Function

Usage

PsFile does work on remote machines. If my login account already has access to the remote share, I can just enter:

psfile \\remote-share

(replace "remote-share" with the name of your file server) and it will list every opened document on that share, along with who has it open, and the file ID if I want to force the file closed. For me, this is a really long list, but it can be narrowed down by entering part of a path:

psfile \\remote-share I:\\Human_Resources

This is kind of tricky, since in my case this remote share is mounted as Z: on my local machine, but psfile identifies paths as they are defined on the remote file server, which in my case is I: (yours will be different). I just had to comb through the results of my first psfile run to see some of the paths it returned and then run it again with a partial path to narrow down the results.

Optionally, PsFile will let you specify credentials for the remote share if you need to supply them for access.

Lastly, a little known tip: if someone clicks on a file in Windows Explorer and cuts or copies the file with the intent to paste it somewhere else, that act also places a lock on the file.

Note that time.gmtime maps timestamp 0 to 1970-1-1 00:00:00.

In [61]: import time       
In [63]: time.gmtime(0)
Out[63]: time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)

time.mktime(time.gmtime(0)) gives you a timestamp shifted by an amount that depends on your locale, which in general may not be 0.

In [64]: time.mktime(time.gmtime(0))
Out[64]: 18000.0

The inverse of time.gmtime is calendar.timegm:

In [62]: import calendar    
In [65]: calendar.timegm(time.gmtime(0))
Out[65]: 0

Did you try the || operator ?

Concatenation Operator Documentation from Oracle >>>

Strings between double quotes "" interpolate, meaning they convert escaped characters to printable characters.

Strings between single quotes '' are literal, meaning they are treated exactly as the characters are typed in.

You can have both on the same line:

echo '$clientid $lastname ' . "\r\n";
echo "$clientid $lastname \r\n";

outputs:

https://docs.microsoft.com/en-us/sql/t-sql/statements/set-ansi-nulls-transact-sql

When SET ANSI_NULLS is ON, a SELECT statement that uses WHERE column_name = NULL returns zero rows even if there are null values in column_name. A SELECT statement that uses WHERE column_name <> NULL returns zero rows even if there are nonnull values in column_name.

For e.g

DECLARE @TempVariable VARCHAR(10)
SET @TempVariable = NULL

SET ANSI_NULLS ON
SELECT 'NO ROWS IF SET ANSI_NULLS ON' where    @TempVariable = NULL
-- IF ANSI_NULLS ON , RETURNS ZERO ROWS


SET ANSI_NULLS OFF
SELECT 'THERE WILL BE A ROW IF ANSI_NULLS OFF' where    @TempVariable =NULL
-- IF ANSI_NULLS OFF , THERE WILL BE ROW !

As clarified in your comment, Spacemoses, you stated an example: WHERE (Note is null) ^ (ID is null). I do not see why you chose to accept any answer given here as answering that. If i needed an xor for that, i think i'd have to use the AND/OR equivalent logic:

WHERE (Note is null and ID is not null) OR (Note is not null and ID is null)

That is equivalent to:

WHERE (Note is null) XOR (ID is null)

when 'XOR' is not available.

If none of the other answers work for you, it may be because you are binding the ContentProperty of a control in the OnLoad function, which means this won't work:

private void UserControl_Load(object sender, RoutedEventArgs e)
{
  Bind.SetBindingElement(labelName, String.Format("{0:0.00}", PropertyName), Label.ContentProperty) 
}

The solution is simple: there is a ContentStringFormat property in the xaml. So when you create the label do this:

//if you want the decimal places definite
<Label Content="0" Name="labelName" ContentStringFormat="0.00"/>

Or

//if you want the decimal places to be optional
<Label Content="0" Name="labelName" ContentStringFormat="0.##"/>

Extension methods I commonly use to solve this problem:

public static string RemoveAfter(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(0, index);
        }
        return value;
    }

    public static string RemoveBefore(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(index + 1);
        }
        return value;
    }

You can link libraries from cdn (Content delivery network):

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

Or link libraries locally, add css files in the css folder and jquery in js folder. You have to keep both folders in the laravel public folder then you can link like below:

<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">
<script src="{{asset('js/jquery.min.js')}}"></script>

or else

{{ HTML::style('css/style.css') }}
{{ HTML::script('js/functions.js') }}

If you link js files and css files locally (like in the last two examples) you need to add js and css files to the js and css folders which are in public\js or public\css not in resources\assets.

You could call an mWebView.reload(); That's what it does

span.login-text {
    font-size: 22px;
    display:table;
    margin-left: auto;
    margin-right: auto;
}

<span class="login-text">Welcome To .....CMP</span>

For me it worked very well. try this also

Add following line

GlobalConfiguration.Configure(WebApiConfig.Register);

in Application_Start() function in Global.ascx.cs file.

You can use range quantifier {min,max} to specify minimum of 1 digit and maximum of 6 digits as:

^[0-9]{1,6}$

Explanation:

^     : Start anchor
[0-9] : Character class to match one of the 10 digits
{1,6} : Range quantifier. Minimum 1 repetition and maximum 6.
$     : End anchor

Why did your regex not work ?

You were almost close on the regex:

^[0-9][0-9]\?[0-9]\?[0-9]\?[0-9]\?[0-9]\?$

Since you had escaped the ? by preceding it with the \, the ? was no more acting as a regex meta-character ( for 0 or 1 repetitions) but was being treated literally.

To fix it just remove the \ and you are there.

See it on rubular.

The quantifier based regex is shorter, more readable and can easily be extended to any number of digits.

Your second regex:

^[0-999999]$

is equivalent to:

^[0-9]$

which matches strings with exactly one digit. They are equivalent because a character class [aaaab] is same as [ab].

if you want the color to change when you have simply add the :hover pseudo

div.e:hover {
    background-color:red;
}

Or you can use the ItemDataBound event in the code behind.

I encountered this error when I use Mysql Cluster, I do not know this question is from a cluster usage or not. As the error is exactly the same, so give my solution here. Getting this error because the data nodes suddenly crash. But when the nodes crash, you can still get the correct result using cmd:

ndb_mgm -e 'ALL REPORT MEMORYUSAGE'

And the mysqld also works correctly.So at first, I can not understand what is wrong. And about 5 mins later, ndb_mgm result shows no data node working. Then I realize the problem. So, try to restart all the data nodes, then the mysql server is back and everything is OK.

But one thing is weird to me, after I lost mysql server for some queries, when I use cmd like show tables, I can still get the return info like 33 rows in set (5.57 sec), but no table info is displayed.

As @Izabela Orlowska pointed out: In my case the problem occurred due to some files that could not be found inside the gradle cache folder. (Windows OS)

The default gradle path was inside my user folder. the path contained umlauts and a space. I moved the gradle folder by setting GRADLE_HOME and GRADLE_USER_HOME environment variable to some newly created folder without umlauts or spaces in path. This fixed the problem for me.

List<string> items = new List<string>();

items.Find(p => p == "blah");

or

items.Find(p => p.Contains("b"));

but this allows you to define what you are looking for via a match predicate...

I guess if you are talking linqToSql then:

example looking for Account...

DataContext dc = new DataContext();

Account item = dc.Accounts.FirstOrDefault(p => p.id == 5);

If you need to make sure that there is only 1 item (throws exception when more than 1)

DataContext dc = new DataContext();

Account item = dc.Accounts.SingleOrDefault(p => p.id == 5);

In Xcode 9 there is a new "Actual Size" option. In the Simulator to the Window menu and choose Scale > Actual Size to trigger it. This takes into account your current screen resolution to ensure the on-screen device matches the physical dimensions of a real device.

Use Excel Online (Google Sheets).. And install Power Tools for Google Sheets.. Then in Google Sheets go to Addons tab and start Power Tools. Then choose Randomize from Power Tools menu. Select Shuffle. Then select choices of your test in excel sheet. Then select Cells in each row and click Shuffle from Power Tools menu. This will shuffle each row's selected cells independently from one another.

Rather than provide a theoretical definition, which are beautifully summarized here already, I'll give a simple example:

Assume the run time of f(i) is O(1). Below is a code fragment whose asymptotic runtime is T(n). It always calls the function f(...) n times. Both the lower and the upper bound is n.

for(int i=0; i<n; i++){
    f(i);
}

The second code fragment below has the asymptotic runtime of O(n). It calls the function f(...) at most n times. The upper bound is n, but the lower bound could be O(1) or O(log(n)), depending on what happens inside f2(i).

for(int i=0; i<n; i++){
    if( f2(i) ) break;
    f(i);
}

Random random = new Random();

double NextDouble(double minimum, double maximum)
{  

    return random.NextDouble()*random.Next(minimum,maximum);

}

if (str.match(/[a-z]/i)) {
    // alphabet letters found
}

From the docs:

The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.

Also:

Lexicographical ordering for strings uses the Unicode code point number to order individual characters.

or on Python 2:

Lexicographical ordering for strings uses the ASCII ordering for individual characters.

As an example:

>>> 'abc' > 'bac'
False
>>> ord('a'), ord('b')
(97, 98)

The result False is returned as soon as a is found to be less than b. The further items are not compared (as you can see for the second items: b > a is True).

In my case, with letsencrypt https, this was caused by using cert.pem instead of fullchain.pem as the certificate file on the requested server. See this thread for details.

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

I made this function for my needs.

Feel free to use it. Works great on mobile devices.

function detectswipe(el,func) {
  swipe_det = new Object();
  swipe_det.sX = 0; swipe_det.sY = 0; swipe_det.eX = 0; swipe_det.eY = 0;
  var min_x = 30;  //min x swipe for horizontal swipe
  var max_x = 30;  //max x difference for vertical swipe
  var min_y = 50;  //min y swipe for vertical swipe
  var max_y = 60;  //max y difference for horizontal swipe
  var direc = "";
  ele = document.getElementById(el);
  ele.addEventListener('touchstart',function(e){
    var t = e.touches[0];
    swipe_det.sX = t.screenX; 
    swipe_det.sY = t.screenY;
  },false);
  ele.addEventListener('touchmove',function(e){
    e.preventDefault();
    var t = e.touches[0];
    swipe_det.eX = t.screenX; 
    swipe_det.eY = t.screenY;    
  },false);
  ele.addEventListener('touchend',function(e){
    //horizontal detection
    if ((((swipe_det.eX - min_x > swipe_det.sX) || (swipe_det.eX + min_x < swipe_det.sX)) && ((swipe_det.eY < swipe_det.sY + max_y) && (swipe_det.sY > swipe_det.eY - max_y) && (swipe_det.eX > 0)))) {
      if(swipe_det.eX > swipe_det.sX) direc = "r";
      else direc = "l";
    }
    //vertical detection
    else if ((((swipe_det.eY - min_y > swipe_det.sY) || (swipe_det.eY + min_y < swipe_det.sY)) && ((swipe_det.eX < swipe_det.sX + max_x) && (swipe_det.sX > swipe_det.eX - max_x) && (swipe_det.eY > 0)))) {
      if(swipe_det.eY > swipe_det.sY) direc = "d";
      else direc = "u";
    }

    if (direc != "") {
      if(typeof func == 'function') func(el,direc);
    }
    direc = "";
    swipe_det.sX = 0; swipe_det.sY = 0; swipe_det.eX = 0; swipe_det.eY = 0;
  },false);  
}

function myfunction(el,d) {
  alert("you swiped on element with id '"+el+"' to "+d+" direction");
}

To use the function just use it like

detectswipe('an_element_id',myfunction);

detectswipe('an_other_element_id',my_other_function);

If a swipe is detected the function "myfunction" is called with parameter element-id and "l,r,u,d" (left,right,up,down).

_{I (UlysseBN) made a new version of this script based on this one which use more modern JavaScript, it looks like it behaves better on some cases. If you think it should rather be an edit of this answer let me know, if you are the original author and you end up editing, I'll delete my answer.}

In my case i had

<android.support.design.widget.NavigationView...

and in app config:

implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.appcompat:appcompat:1.1.0'

So I changed the XML to:

com.google.android.material.navigation.NavigationView...

Scott Murray wrote a great explanation of this^[1]. For instance, for the code snippet:

svg.append("g")
    .attr("class", "axis")
    .attr("transform", "translate(0," + h + ")")
    .call(xAxis);

He explains using the following:

Note that we use attr() to apply transform as an attribute of g. SVG transforms are quite powerful, and can accept several different kinds of transform definitions, including scales and rotations. But we are keeping it simple here with only a translation transform, which simply pushes the whole g group over and down by some amount.

Translation transforms are specified with the easy syntax of translate(x,y), where x and y are, obviously, the number of horizontal and vertical pixels by which to translate the element.

The solution found here helped us to update master to a previous commit that had already been pushed:

git checkout master
git reset --hard e3f1e37
git push --force origin e3f1e37:master

The key difference from the accepted answer is the commit hash "e3f1e37:" before master in the push command.

If anyone else is having a nullptr on the searchview variable, I found out that the item setup is a tiny bit different:

old:

android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView"

new:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="androidx.appcompat.widget.SearchView"

pre-android x:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

You can also use .reverse(). It's a native array function

<div ng-repeat="friend in friends.reverse()">{{friend.name}}</div>

For Sublime Text Editor

Indentation Error generally occurs when the code contains a mix of both tabs and spaces for indentation. I have got a very nice solution to correct it, just open your code in a sublime text editor and find 'Tab Size' in the bottom right corner of Sublime Text Editor and click it. Now select either

'Convert Indentation to Spaces'

OR

'Convert Indentation to Tabs'

Your code will work in either case.

Additionally, if you want Sublime text to do it automatically for you for every code you can update the Preference settings as below:-

Sublime Text menu > Preferences > Settings - Syntax Specific :

Python.sublime-settings

{
    "tab_size": 4,
    "translate_tabs_to_spaces": true
}

You could make it into a module and expose your inner function by returning it in an Object.

function outer() { 
    function inner() {
        console.log("hi");
    }
    return {
        inner: inner
    };
}
var foo = outer();
foo.inner();

Check the GridView1.SelectedRow is not null:

if (GridView1.SelectedRow == null) return;
string DeleteThis = GridView1.SelectedRow.Cells[0].Text;

A previous answer using LPAD() is optimal. However, in the event you want to do special or advanced processing, here is a method that allows more iterative control over the padding. Also serves as an example using other constructs to achieve the same thing.

UPDATE
    mytable
SET
    mycolumn = CONCAT(
        REPEAT(
            "0",
            8 - LENGTH(mycolumn)
        ),
        mycolumn
    )
WHERE
    LENGTH(mycolumn) < 8;

Several of the above suggestions count the number of LINES in the csv file. But some CSV files will contain quoted strings which themselves contain newline characters. MS CSV files usually delimit records with \r\n, but use \n alone within quoted strings.

For a file like this, counting lines of text (as delimited by newline) in the file will give too large a result. So for an accurate count you need to use csv.reader to read the records.

In my case i use imgur and use the direct link this way.

![img](http://i.imgur.com/yourfilename.png)

SELECT  host_name
FROM    v$instance

You can use like bellow:

(( var0 = var1<98?9:21 ))

the same as

if [ "$var1" -lt 98 ]; then
   var0=9
else
   var0=21
fi

extends

condition?result-if-true:result-if-false

I found the interested thing on the book "Advanced Bash-Scripting Guide"

In Place of using this

MsgBox(json.SelectToken("Venue").SelectToken("ID"))

You can also use

MsgBox(json.SelectToken("Venue.ID"))

if you need a simple solution for this see:

new Date('1993-01-20'.split('-')); 

For complex select with ORDER BY I use the following:

SELECT * FROM (
    SELECT 'Column name #1', 'Column name #2', 'Column name ##'
    UNION ALL
    (
        // complex SELECT statement with WHERE, ORDER BY, GROUP BY etc.
    )
) resulting_set
INTO OUTFILE '/path/to/file';

look at sysinternals for a variety of tools to help you achieve that goal. psService for example would restart a service on a remote machine.

the "file://" url protocol can only be used to locate files in the file system of the local machine. since this html code is interpreted by a browser, the "local machine" is the machine that is running the browser.

if you are getting file not found errors, i suspect it is because the file is not found. however, it could also be a security limitation of the browser. some browsers will not let you reference a filesystem file from a non-filesystem html page. you could try using the file path from the command line on the machine running the browser to confirm that this is a browser limitation and not a legitimate missing file.

Thomas, I think your wrapper code, or just the condition itself, is the cleanest way to do what you want to do in java, which is convert "1" to the Boolean True value. Actually, comparing to "0" and taking the inverse would match the C behavior of treating 0 as false and everything else as true.

Boolean intStringToBoolean(numericBooleanValueString) {
  return !"0".equals(numericBooleanValueString);
}

    foreach (GridViewRow row in GridView1.Rows)
    {
        CheckBox chkbox = (CheckBox)row.FindControl("CheckBox1");
        if (chkbox.Checked == true)
        {
            // Your Code
        }
    }

Caching, sometime you have to calculate the same value lots of time so by storing the last set of inputs to a method and the result you can speed the code up. By using Thread Local Storage you avoid having to think about locking.

Just to make things even worse, in some situations, no-cache can't be used, but no-store can:

df.columns.values also give us the column names

The way I cam across this question was when I tried doing something similar where I was defining a function and it was being called with the array like others pointed out

You could do something like this however for this scenarios its less elegant compared to Sven's method.

sapply(a, function(x) afunc(x))

afunc<-function(a){
  if (a>0){
    a/sum(a)
  }
  else 1
}

ARIA does not change functionality, it only changes the presented roles/properties to screen reader users. WebAIM’s WAVE toolbar identifies ARIA roles on the page.

It seems like what you're looking for is a variant on the CSS Holy Grail Layout, but in two columns. Check out the resources at this answer for more information.

In my case, this error was caused by an identical server instance already running background.

The weird thing is when I started my server without notice there's one running already, the console didn't show anything like 'something is using port xxx'. I could even upload something to the server. So, it took me quite long to locate this problem.

What's more, after closing all the applications I can imagine, I still could not find the process which is using this port in my Mac's activity monitor. I have to use lsof to trace. The culprit was not surprising - it's a node process. However, with the PID shown in the terminal, I found the port number in the monitor is different from the one used by my server.

All in all, kill all the node processes may solve this problem directly.

I have explained use of various CURL options required for CURL PROXY.

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

Others have given you the answer about appendChild.

Calling document.write() on a page that is not open (e.g. has finished loading) first calls document.open() which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.

Here's what the official naming conventions document prescribes:

Packages

The prefix of a unique package name is always written in all-lowercase ASCII letters and should be one of the top-level domain names, currently com, edu, gov, mil, net, org, or one of the English two-letter codes identifying countries as specified in ISO Standard 3166, 1981.

Subsequent components of the package name vary according to an organization's own internal naming conventions. Such conventions might specify that certain directory name components be division, department, project, machine, or login names.

Examples

• com.sun.eng
• com.apple.quicktime.v2
• edu.cmu.cs.bovik.cheese

References

• java.sun.com - Code Conventions/Naming

Note that in particular, anything following the top-level domain prefix isn't specified by the above document. The JLS also agrees with this by giving the following examples:

• com.sun.sunsoft.DOE
• gov.whitehouse.socks.mousefinder
• com.JavaSoft.jag.Oak
• org.npr.pledge.driver
• uk.ac.city.rugby.game

The following excerpt is also relevant:

In some cases, the internet domain name may not be a valid package name. Here are some suggested conventions for dealing with these situations:

• If the domain name contains a hyphen, or any other special character not allowed in an identifier, convert it into an underscore.
• If any of the resulting package name components are keywords then append underscore to them.
• If any of the resulting package name components start with a digit, or any other character that is not allowed as an initial character of an identifier, have an underscore prefixed to the component.

References

• JLS 6.1 Package Names

Event though ,oment.js does not provide such functionality, if you come here and you are already using moment.js, try this:

function formatDuration(ms) {
  var duration = moment.duration(ms);
  return Math.floor(duration.asHours()) + moment.utc(duration.asMilliseconds()).format(":mm:ss");
}

You will get something like x:xx:xx.

In the case you may want to skip the hour, when the duration is only < 60minutes.

function formatDuration(ms) {
  var duration = moment.duration(ms);
  if (duration.asHours() > 1) {
    return Math.floor(duration.asHours()) + moment.utc(duration.asMilliseconds()).format(":mm:ss");
  } else {
    return moment.utc(duration.asMilliseconds()).format("mm:ss");
  }
}

This workaround in moment was introduced in this Issue.

I tried everything in the previous answer and couldn't find a .vimrc file, so I had to make one.

I copied the example file, cp vimrc_example.vim ~/.vimrc.

I had to create the file, copying from /usr/share/vim/vim74/vimrc_example.vim to ~/.vimrc. Those were the instructions in the vimrc_example file.

My solution is for Unix for other operating systems. According to the Vim documentation, your destination path should be as follows:

    For Unix and OS/2   : ~/.vimrc
    For Amiga           : s:.vimrc
    For MS-DOS and Win32: $VIM\_vimrc
    For OpenVMS         : sys$login:.vimrc

I tried this:

android:backgroundTint:"@color/mycolor"

instead of changing background property. This does not remove the material effect.

Be careful with the "Range(...)" without first qualifying a Worksheet because it will use the currently Active worksheet to make the copy from. It's best to fully qualify both sheets. Please give this a shot (please change "Sheet1" with the copy worksheet):

No, this is not possible. However, one could do something like this:

List<Integer> temp = new ArrayList<Integer>();
temp.add(Integer.valueOf(0));
temp.add(Integer.valueOf(2));
temp.add(Integer.valueOf(3));
temp.add(Integer.valueOf(4));
List<Integer> immutable = Collections.unmodifiableList(temp);

This requires using wrappers, and is a List, not an array, but is the closest you will get.

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

I was going out of my mind when a rule was being ignored while others weren't. Run your CSS through a validator and look for parsing errors.

I accidentally used // for a comment instead of /* */ causing odd behavior. My IDE said nothing about it. I hope it helps someone.

I'm not quite sure what you're attempting to use the div for, but this is an example with some random text.

Mr_Green gave the correct instructions when he said to add overflow-y: auto as that restricts it to vertical scrolling. This is a JSFiddle example:

JSFiddle

If you don't need the change to animate then you don't need to use any special plugins - I'd just use the native JavaScript window.scrollTo() method -- passing in 0, 0 will scroll the page to the top left instantly.

window.scrollTo(xCoord, yCoord);

Parameters

• xCoord is the pixel along the horizontal axis.
• yCoord is the pixel along the vertical axis.

This was impossible in 2008, but it's becoming possible soon (hopefully)!

According to The W3C CSS3 specification, you can have full control over any number, glyph, or other symbol generated before a list item with the ::marker pseudo-element. To apply this to the most voted answer's solution:

<ul>
  <li>item #1</li>
  <li>item #2</li>
  <li>item #3</li>
</ul>

li::marker {
  color: red; /* bullet color */
}
li {
  color: black /* text color */
}

Note, though, that as of July 2016, this solution is only a part of the W3C Working Draft and does not work in any major browsers, yet.

• Gecko (Firefox, Iceweasel, etc.): Click "(vote)" on this bug
• Trident (IE, Windows web views): Click "I can too" under "X User(s) can reproduce this bug"

• Webkit (Safari, Steam, WebOS, etc.): CC yourself to this bug

Works for me, has nothing to do with PHP 5.3. Just like many such options it cannot be overriden via ini_set() when safe_mode is enabled. Check your updated php.ini (and better yet: change the memory_limit there too).

Add something like this to lib/__init__.py

from .helperclass import Helper

now you can import it directly:

from lib import Helper

For the example you gave, use default values:

class City:
    def __init__(self, name="Default City Name"):
        ...
    ...

In general, you have two options:

1) Do if-elif blocks based on the type:

def __init__(self, name):
    if isinstance(name, str):
        ...
    elif isinstance(name, City):
        ...
    ...

2) Use duck typing --- that is, assume the user of your class is intelligent enough to use it correctly. This is typically the preferred option.

For reference, the solution is:

UPDATE mysql.user SET host = '10.0.0.%' WHERE host = 'internalfoo' AND user != 'root';
UPDATE mysql.db SET host = '10.0.0.%' WHERE host = 'internalfoo' AND user != 'root';

In order to wrap text in the code editor in IntelliJ IDEA 2020.1 community follow these steps:

Ctrl + Shift + "A" OR Help -> Find Action
Enter: "wrap" into the text box
Toggle: View | Active Editor Soft-Wrap "ON"

footerText {
    line-height: 20px;
}

you don't need to start playing with position or even layout of other elements... use this simple solution

try this:

<IfModule mod_headers.c>
     Header set Access-Control-Allow-Credentials true
     Header set Access-Control-Allow-Origin "your domain"
     Header set Access-Control-Allow-Headers "X-Requested-With"
</IfModule>

It's preferable to allow a list of know trusted host.

Update (2017/01/05):

GitHub has published an update that allows you now to search within commit messages from within their UI. See blog post for more information.

I had the same question and contacted someone GitHub yesterday:

Since they switched their search engine to Elasticsearch it's not possible to search for commit messages using the GitHub UI. But that feature is on the team's wishlist.

Unfortunately there's no release date for that function right now.

You can make two applications listen for the same port on the same network interface.

There can only be one listening socket for the specified network interface and port, but that socket can be shared between several applications.

If you have a listening socket in an application process and you fork that process, the socket will be inherited, so technically there will be now two processes listening the same port.

Check out from dateutil.relativedelta import * for adding a specific amount of time to a date, you can continue to use timedelta for the simple stuff i.e.

use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)

or you can start using relativedelta

use_date = use_date+relativedelta(months=+1)

use_date = use_date+relativedelta(years=+1)

for the last day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)

Right now this will provide 29/02/2016

for the penultimate day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)

last Friday of the next month:

use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))

2nd Tuesday of next month:

new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))

As @mrroot5 points out dateutil's rrule functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.

from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)

#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)

#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
    print(ld)

#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
    print(tuesday)

This is by no means an exhaustive list of what is available. Documentation is available here: https://dateutil.readthedocs.org/en/latest/

One point: you have to set NumberFormat property BEFORE loading the value into the cell. I had a nine digit number that still displayed as 9.14E+08 when the NumberFormat was set after the cell was loaded. Setting the property before loading the value made the number appear as I wanted, as straight text.

OR:

Could you try an autofit first:

Excel_Obj.Columns("A:V").EntireColumn.AutoFit

use the following code,

    iv.setImageResource(getResources().getIdentifier("apple", "drawable", getPackageName()));

Regarding apply vs map:

pool.apply(f, args): f is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args).

pool.map(f, iterable): This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.

An old post but thought i would share an answer for anyone looking. And because when you use absolute things can go wrong. What I would do is

HTML

<div id="parentDiv"></div>
<div class="childDiv"></div>

The Css

parentDiv{

}
childDiv{
    height:40px;
    margin-top:-20px;
}

And that would just sit that bottom div back up into the parent div. safe for most browsers too

As you noted, -Dmaven.test.skip=true skips compiling the tests. More to the point, it skips building the test artifacts. A common practice for large projects is to have testing utilities and base classes shared among modules in the same project.

This is accomplished by having a module require a test-jar of a previously built module:

<dependency>
  <groupId>org.myproject.mygroup</groupId>
  <artifactId>common</artifactId>
  <version>1.0</version>
  <type>test-jar</type>
  <scope>test</scope>
</dependency>

If -Dmaven.test.skip=true (or simply -Dmaven.test.skip) is specified, the test-jars aren't built, and any module that relies on them will fail its build.

In contrast, when you use -DskipTests, Maven does not run the tests, but it does compile them and build the test-jar, making it available for the subsequent modules.

You should always use following syntax to rethrow an exception, else you'll stomp the stack trace:

throw;

If you print the trace resulting from "throw ex", you'll see that it ends on that statement and not at the real source of the exception.

Basically, it should be deemed a criminal offense to use "throw ex".

Add the key "View Controller-based status bar appearance" from the dropdownlist as a row in info.plist. Something like this:

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.

If your GridView is databond, make an index column in the resultset you retrive like this:

select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]

In the command control you want to use make the value of CommandArgument property equal to the row index of the DataSet table RowIndex like this:

<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />

Use the OnRowCommand event to fire on clicking the link button like this:

<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">

Finally the code behind you can then do whatever you like when the event is triggered like this:

protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
    if(pnlMsgBody.Visible == false)
    {
        pnlMsgBody.Visible = true;
    }
    else
    {
        pnlMsgBody.Visible = false;
    }
}

The other answers are fine. However, you can also pass Collectors.toList() as parameter to Stream.collect() to return the elements as an ArrayList.

System.out.println( list.stream().map( e -> e.toString() ).collect( toList() ) );

The slick-slide has inner wrapping div which you can use to create spacing between slides without breaking the design:

.slick-list {margin: 0 -5px;}
.slick-slide>div {padding: 0 5px;}

In jQuery you can do like this.

function random_no(){_x000D_
     var ran=Math.random();_x000D_
     jQuery('#random_no_container').html(ran);_x000D_
}_x000D_
           _x000D_
window.setInterval(function(){_x000D_
       /// call your function here_x000D_
      random_no();_x000D_
}, 6000);  // Change Interval here to test. For eg: 5000 for 5 sec

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="random_no_container">_x000D_
      Hello. Here you can see random numbers after every 6 sec_x000D_
</div>

Unfortunately, it's not completely portable. It's usually integral, but it can be any "integer or real-floating type".

See Should my constructors use "initialization lists" or "assignment"?

Briefly: in your specific case, it does not change anything. But:

• for class/struct members with constructors, it may be more efficient to use option 1.
• only option 1 allows you to initialize reference members.
• only option 1 allows you to initialize const members
• only option 1 allows you to initialize base classes using their constructor
• only option 2 allows you to initialize array or structs that do not have a constructor.

My guess for why option 2 is more common is that option 1 is not well-known, neither are its advantages. Option 2's syntax feels more natural to the new C++ programmer.

In this scenario, create another shared module in that import all the component which is being used in multiple module.

In shared component. declare those component. And then import shared module in appmodule as well as in other module where you want to access. It will work 100% , I did this and got it working.

@NgModule({
    declarations: [HeaderComponent, NavigatorComponent],
    imports: [
        CommonModule, BrowserModule,
        AppRoutingModule,
        BrowserAnimationsModule,
        FormsModule,
    ] 
})
export class SharedmoduleModule { }
const routes: Routes = [
{
    path: 'Parent-child-relationship',
    children: [
         { path: '', component: HeaderComponent },
         { path: '', component: ParrentChildComponent }
    ]
}];
@NgModule({
    declarations: [ParrentChildComponent, HeaderComponent],
    imports: [ RouterModule.forRoot(routes), CommonModule, SharedmoduleModule ],
    exports: [RouterModule]
})
export class TutorialModule {
}
imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    FormsModule,
    MatInputModule,
    MatButtonModule,
    MatSelectModule,
    MatIconModule,
    SharedmoduleModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

in priciple it's the same idea as @Landeeyos. anyhow, expanding on that response: a bit late to the party but here are my two cents:

scenario:

I have a unique case of adding some (roughly 28 text files) predefined, template files with my WPF application. So, the idea is that everytime this app is to be installed, these template, text files will be readily available for usage. anyhow, what I did was that made a seperate library to hold the files by adding a resource.resx. Then I added all those files to this resource file (if you double click a .resx file, its designer gets opened in visual studio). I had set the Access Modifier to public for all. Also, each file was marked as an embedded resource via the Build Action of each text file (you can get that by looking at its properties). let's call this bibliothek1.dll i referenced this above library (bibliothek1.dll) in another library (call it bibliothek2.dll) and then consumed this second library in mf wpf app.

actual fun:

        // embedded resource file name <i>with out extension</i>(this is vital!) 

        string fileWithoutExt = Path.GetFileNameWithoutExtension(fileName);

        // is required in the next step

        // without specifying the culture
        string wildFile = IamAResourceFile.ResourceManager.GetString(fileWithoutExt);
        Console.Write(wildFile);

        // with culture
        string culturedFile = IamAResourceFile.ResourceManager.GetString(fileWithoutExt, CultureInfo.InvariantCulture);
        Console.Write(culturedFile);

I hope it helps someone, some day, somewhere!

In your flask code, you should ideally specify the MIME type as often as possible, as well:

return html_page_str, 200, {'ContentType':'text/html'}

return json.dumps({'success':True}), 200, {'ContentType':'application/json'}

...etc

document.getElementById('id').value

Heap just guarantees that elements on higher levels are greater (for max-heap) or smaller (for min-heap) than elements on lower levels, whereas BST guarantees order (from "left" to "right"). If you want sorted elements, go with BST.

For anyone else and just an addition to Robert, If your nav has flex display value, you can float the element that you need to the right, by adding this to its css

{
    margin-left: auto;
}

As mentioned above by Vadim Use Jenkins "Project-based Matrix Authorization Strategy" under "Manage Jenkins" => "Configure System". Don't forget to add your admin user there and give all permissions. Now add the restricted user there and give overall read access. Then go to the configuration page of each project, you now have "Enable project-based security" option. Now add each user you want to authorize.

I heard Jeff/Joel talk about this on the podcast today (episode 34, 2008-12-16 (MP3, 31 MB), 1 h 03 min 38 secs - 1 h 06 min 45 secs), and I thought I recalled Stack Overflow was using LINQ to SQL, but maybe it was ditched. Here's the same thing in LINQ to SQL.

var inValues = new [] { "ruby","rails","scruffy","rubyonrails" };

var results = from tag in Tags
              where inValues.Contains(tag.Name)
              select tag;

That's it. And, yes, LINQ already looks backwards enough, but the Contains clause seems extra backwards to me. When I had to do a similar query for a project at work, I naturally tried to do this the wrong way by doing a join between the local array and the SQL Server table, figuring the LINQ to SQL translator would be smart enough to handle the translation somehow. It didn't, but it did provide an error message that was descriptive and pointed me towards using Contains.

Anyway, if you run this in the highly recommended LINQPad, and run this query, you can view the actual SQL that the SQL LINQ provider generated. It'll show you each of the values getting parameterized into an IN clause.

The Zeus editor has support for C/C++ and it also has a form of intellisensing.

It does its intellisensing using the tags information produced by ctags:

alt text http://www.zeusedit.com/images/_lookmain.jpg

DateTime dt = DateTime.Now;

String.Format("{0:dd-MM-yyyy}", dt);

simple as this myObj.name = value;

you shoud do like this form your code

DataGridView.DataSource = yourlist;

DataGridView.DataBind();

myControl.Left = (this.ClientSize.Width - myControl.Width) / 2 ;
myControl.Top = (this.ClientSize.Height - myControl.Height) / 2;

The following sets up the situation I had, using table variables.

DECLARE @Object_Table TABLE
(
    Id INT NOT NULL PRIMARY KEY
)

DECLARE @Link_Table TABLE
(
    ObjectId INT NOT NULL,
    DataId INT NOT NULL
)

DECLARE @Data_Table TABLE
(
    Id INT NOT NULL Identity(1,1),
    Data VARCHAR(50) NOT NULL
)

-- create two objects '1' and '2'
INSERT INTO @Object_Table (Id) VALUES (1)
INSERT INTO @Object_Table (Id) VALUES (2)

-- create some data
INSERT INTO @Data_Table (Data) VALUES ('Data One')
INSERT INTO @Data_Table (Data) VALUES ('Data Two')

-- link all data to first object
INSERT INTO @Link_Table (ObjectId, DataId)
SELECT Objects.Id, Data.Id
FROM @Object_Table AS Objects, @Data_Table AS Data
WHERE Objects.Id = 1

Thanks to another answer that pointed me towards the OUTPUT clause I can demonstrate a solution:

-- now I want to copy the data from from object 1 to object 2 without looping
INSERT INTO @Data_Table (Data)
OUTPUT 2, INSERTED.Id INTO @Link_Table (ObjectId, DataId)
SELECT Data.Data
FROM @Data_Table AS Data INNER JOIN @Link_Table AS Link ON Data.Id = Link.DataId
                INNER JOIN @Object_Table AS Objects ON Link.ObjectId = Objects.Id 
WHERE Objects.Id = 1

It turns out however that it is not that simple in real life because of the following error

the OUTPUT INTO clause cannot be on either side of a (primary key, foreign key) relationship

I can still OUTPUT INTO a temp table and then finish with normal insert. So I can avoid my loop but I cannot avoid the temp table.

For me, I go to \eclipse\configuration.settings\org.eclipse.core.net.prefs set the property systemProxiesEnabled to true manually and restart eclipse.

I ran across this error recently using a javascript library which changes the parameters of a function based on conditions.

You can test an object to see if it has the function. I would only do this in scenarios where you don't control what is getting passed to you.

if( param.indexOf != undefined ) {
   // we have a string or other object that 
   // happens to have a function named indexOf
}

You can test this in your browser console:

> (3).indexOf == undefined;
true

> "".indexOf == undefined;
false

It's part of the ES6 module system, described here. There is a helpful example in that documentation, also:

If a module defines a default export:

export default function() { console.log("hello!") }

then you can import that default export by omitting the curly braces:

import foo from "foo";
foo(); // hello!

Update: As of June 2015, the module system is defined in §15.2 and the export syntax in particular is defined in §15.2.3 of the ECMAScript 2015 specification.
