For Visual Studio you'll want to right click on your project in the solution explorer and then click on Properties.

Next open Configuration Properties and then Linker.

Now you want to add the folder you have the Allegro libraries in to Additional Library Directories,

Linker -> Input you'll add the actual library files under Additional Dependencies.

For the Header Files you'll also want to include their directories under C/C++ -> Additional Include Directories.

If there is a dll have a copy of it in your main project folder, and done.

I would recommend putting the Allegro files in the your project folder and then using local references in for the library and header directories.

Doing this will allow you to run the application on other computers without having to install Allergo on the other computer.

This was written for Visual Studio 2008. For 2010 it should be roughly the same.

My advise is: try not to rely on dependencies when you can easily do it with few lines of codes

Here's what you're trying to achieve in 14 lines of code:

fs.isDir = function(dpath) {
    try {
        return fs.lstatSync(dpath).isDirectory();
    } catch(e) {
        return false;
    }
};
fs.mkdirp = function(dirname) {
    dirname = path.normalize(dirname).split(path.sep);
    dirname.forEach((sdir,index)=>{
        var pathInQuestion = dirname.slice(0,index+1).join(path.sep);
        if((!fs.isDir(pathInQuestion)) && pathInQuestion) fs.mkdirSync(pathInQuestion);
    });
};

I no longer work on Android project for a while. Although the below provides some clue to how an android studio project can be configured, but I can't guarantee it works flawlessly.

In principle, IntelliJ respects the build file and will try to use it to configure the IDE project. It's not true in the other way round, IDE changes normally will not affect the build file.

Since most Android projects are built by Gradle, it's always a good idea to understand this tool.

I'd suggest referring to @skyfishjy's answer, as it seems to be more updated than this one.

The below is not updated

Although android studio is based on IntelliJ IDEA, at the same time it relies on gradle to build your apk. As of 0.2.3, these two doesn't play nicely in term of configuring from GUI. As a result, in addition to use the GUI to setup dependencies, it will also require you to edit the build.gradle file manually.

Assuming you have a Test Project > Test structure. The build.gradle file you're looking for is located at TestProject/Test/build.gradle

Look for the dependencies section, and make sure you have

compile 'com.android.support:support-v4:13.0.+'

Below is an example.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

You can also add 3rd party libraries from the maven repository

compile group: 'com.google.code.gson', name: 'gson', version: '2.2.4'

The above snippet will add gson 2.2.4 for you.

In my experiment, it seems that adding the gradle will also setup correct IntelliJ dependencies for you.

I find this Java version manager called Jabba recently and the usage is very similar to version managers of other languages like rvm(ruby), nvm(node), pyenv(python), etc. Also it's cross platform so definitely it can be used on Mac.

After installation, it will create a dir in ~/.jabba to put all the Java versions you install. It "Supports installation of Oracle JDK (default) / Server JRE, Zulu OpenJDK (since 0.3.0), IBM SDK, Java Technology Edition (since 0.6.0) and from custom URLs.".

Basic usage is listed on their Github. A quick summary to start:

curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | bash && . ~/.jabba/jabba.sh

# install Oracle JDK
jabba install 1.8 # "jabba use 1.8" will be called automatically  
jabba install 1.7 # "jabba use 1.7" will be called automatically 

# list all installed JDK's
jabba ls

# switch to a different version of JDK
jabba use 1.8

This method orderBy does not change the input array, you have to assign the result to your array :

var chars = this.state.characters;

chars = _.orderBy(chars, ['name'],['asc']); // Use Lodash to sort array by 'name'

 this.setState({characters: chars})

I am using Idea based Android Studio (some people are talking about eclipse one here)

When I launch the app in the emulator (using the Run App button of Android Studio) AVD shows up but the app does not launch or run.

However when I connect my mobile and launch the app on my mobile the App works (this itself took some time, enabling developer options on mobile and doing the right configuration)

• Because My app is launching on connected mobile, I can say nothing wrong with App.
• There is some problem with AVD integration which I could not figure out so As of now I am working around my problem following way.

1 - I installed the app manually by dragging the APK file on AVD. (APK file is app\build\outputs\apk\debug folder)

2 - Then my AVD was not showing the installed APP list. 3 - I searched my APP using Google bar on AVD and dragged the APP icon on the home screen of AVD.

4 - I can now launch the APP using my APP icon on the home screen of AVD.

That's how I am working around my problem. I will try to debug more on why it does not get installed and launched directly.

I have verified that Run App Icon does install the Application. Installation, not launching, appears to be the problem for me.

Can I control the HTTP headers sent by window.open (cross browser)?

No

If not, can I somehow window.open a page that then issues my request with custom headers inside its popped-up window?

• You can request a URL that triggers a server side program which makes the request with arbitrary headers and then returns the response
• You can run JavaScript (probably saying goodbye to Progressive Enhancement) that uses XHR to make the request with arbitrary headers (assuming the URL fits within the Same Origin Policy) and then process the result in JS.

I need some cunning hacks...

It might help if you described the problem instead of asking if possible solutions would work.

Only one suggestion instead of 9 you can use KeyCodes.TAB.

This turned out way more complex then I first suspected, and I guess that's what intrigued me, I searched every where and all the methods given wouldnt work on Windows 7.

So I have an alternate solution which uses a Visual Basic Script.

The batch creates and executes the script(DayOfWeek.vbs), assigns the scripts output (Monday, Tuesday etc) to a variable (dow), the variable is then checked and another variable (dpwnum) assigned with the days number, afterwards the VBS is deleted hope it helps:

@echo off

REM Create VBS that will get day of week in same directory as batch
echo wscript.echo WeekdayName(Weekday(Date))>>DayOfWeek.vbs

REM Cycle through output to get day of week i.e monday,tuesday etc
for /f "delims=" %%a in ('cscript /nologo DayOfWeek.vbs') do @set dow=%%a

REM delete vbs
del DayOfWeek.vbs

REM Used for testing outputs days name
echo %dow%

REM Case of the days name is important must have a capital letter at start
REM Check days name and assign value depending
IF %dow%==Monday set downum=0
IF %dow%==Tuesday set downum=1
IF %dow%==Wednesday set downum=2
IF %dow%==Thursday set downum=3
IF %dow%==Friday set downum=4
IF %dow%==Saturday set downum=5
IF %dow%==Sunday set downum=6

REM print the days number 0-mon,1-tue ... 6-sun
echo %downum%

REM set a file name using day of week number
set myfile=%downum%.bak

echo %myfile%

pause
exit

EDIT:

Though I turned to VBS, It can be done in pure batch, took me a while to get it working and a lot of searching lol, but this seems to work:

 @echo off
SETLOCAL enabledelayedexpansion
SET /a count=0
FOR /F "skip=1" %%D IN ('wmic path win32_localtime get dayofweek') DO (
    if "!count!" GTR "0" GOTO next
    set dow=%%D
    SET /a count+=1
)
:next
echo %dow%
pause

The only caveat for you on the above batch is that its day of weeks are from 1-7 and not 0-6

Set Jquery in scope

$scope.$ = $;

and call in html

ng-click="$('#novoModelo').modal('show')"

s.replace(u'Â ', '')              # u before string is important

and make your .py file unicode.

This will get the index of the selected option on change:

$('select').change(function(){_x000D_
    console.log($('option:selected',this).index()); _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select name="CCards">_x000D_
<option value="0">Select Saved Payment Method:</option>_x000D_
<option value="1846">test  xxxx1234</option>_x000D_
<option value="1962">test2  xxxx3456</option>_x000D_
</select>

1. Checkout to temporary branch with last commit

   git branch temp HEAD@{1}

2. Reset last commit

   git reset temp

3. Now, you'll have all files your commit as well as previous commit. Check status of all the files.

   git status

4. Reset your commit files from git stage.

   git reset myfile1.js (so on)

5. Reattach this commit

   git commit -C HEAD@{1}

6. Add and commit your files to new commit.

As best coding practices suggests, use setTimeout instead of setInterval.

function foo() {

    // your function code here

    setTimeout(foo, 5000);
}

foo();

Please note that this is NOT a recursive function. The function is not calling itself before it ends, it's calling a setTimeout function that will be later call the same function again.

The embedded code of youtube has autoplay off by default. Simply add autoplay=1at the end of "src" attribute. For example:

<iframe src="http://www.youtube.com/embed/xzvScRnF6MU?autoplay=1" width="960" height="447" frameborder="0" allowfullscreen></iframe>

In order for TypeScript Compiler to use all visible Type Definitions during compilation, types option should be removed completely from compilerOptions field in tsconfig.json file.

This problem arises when there exists some types entries in compilerOptions field, where at the same time jest entry is missing.

So in order to fix the problem, compilerOptions field in your tscongfig.json should either include jest in types area or get rid of types comnpletely:

{
  "compilerOptions": {
    "esModuleInterop": true,
    "target": "es6",
    "module": "commonjs",
    "outDir": "dist",
    "types": ["reflect-metadata", "jest"],  //<--  add jest or remove completely
    "moduleResolution": "node",
    "sourceMap": true
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ]
}

I think I will go for the duck typing approach - "if it walks like a duck, it quacks like a duck, its a duck". This way you will need not worry about if the string is a unicode or ascii.

Here is what I will do:

In [53]: s='somestring'

In [54]: u=u'someunicodestring'

In [55]: d={}

In [56]: for each in s,u,d:
    if hasattr(each, 'keys'):
        print list(set(each.values()))
    elif hasattr(each, 'lower'):
        print [each]
    else:
        print "error"
   ....:         
   ....:         
['somestring']
[u'someunicodestring']
[]

The experts here are welcome to comment on this type of usage of ducktyping, I have been using it but got introduced to the exact concept behind it lately and am very excited about it. So I would like to know if thats an overkill to do.

Almost assuredly there is something wrong with the content that would be inserted into the genfile. Eclipse is not smart enough to show what the problems are or even indicate that there are problems!

Think about the last edit you made to any of the XML or image content - and try to 'rollback' your changes, manually if necessary.

I find that sometimes Eclipse does not like my file names for whatever reason, and I have to change them.

So add to the resources one by one assuring that it all 'works'. When something breaks, just try changing it a little bit until Eclipse accepts it.

You know it's working when the genfile appears - it will do so automatically if there are no problems.

You need to modify the privileges of the folder you're trying to delete from/save to. Right-click on the containing folder and use the Security tab to permit modify rights for the user your application runs under.

Use the CSS function from jQuery to set styles to your items :

$('#buttonId').css({ "background-color": 'brown'});

Technically possible. You would probably reference employees_ce in deductions and employees_sn. But why don't you merge employees_sn and employees_ce? I see no reason why you have two table. No one to many relationship. And (not in this example) many columns.

If you do two references for one column, an employee must have an entry in both tables.

There's also now this option: http://code.google.com/p/csharp-sqlite/ - a complete port of SQLite to C#.

Go to file "settings.json" and disable the Python pydocstyle:

"python.linting.pydocstyleEnabled": false

Using the snippet provided by Richard, you can encrypt the password before saving it. The preferences API however doesn't provide an easy way to intercept the value and encrypt it - you can block it being saved via an OnPreferenceChange listener, and you theoretically could modify it through a preferenceChangeListener, but that results in an endless loop.

I had earlier suggested adding a "hidden" preference in order to accomplish this. It's definitely not the best way. I'm going to present two other options that I consider to be more viable.

First, the simplest, is in a preferenceChangeListener, you can grab the entered value, encrypt it, and then save it to an alternative preferences file:

  public boolean onPreferenceChange(Preference preference, Object newValue) {
      // get our "secure" shared preferences file.
      SharedPreferences secure = context.getSharedPreferences(
         "SECURE",
         Context.MODE_PRIVATE
      );
      String encryptedText = null;
      // encrypt and set the preference.
      try {
         encryptedText = SimpleCrypto.encrypt(Preferences.SEED,(String)newValue);

         Editor editor = secure.getEditor();
         editor.putString("encryptedPassword",encryptedText);
         editor.commit();
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      // always return false.
      return false; 
   }

The second way, and the way I now prefer, is to create your own custom preference, extending EditTextPreference, @Override'ing the setText() and getText() methods, so that setText() encrypts the password, and getText() returns null.

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

Unfortunately this was a limitation of Firebase Notifications in SDK 9.0.0-9.6.1. When the app is in the background the launcher icon is use from the manifest (with the requisite Android tinting) for messages sent from the console.

With SDK 9.8.0 however, you can override the default! In your AndroidManifest.xml you can set the following fields to customise the icon and color:

<meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/notification_icon" />
<meta-data android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/google_blue" />

Note that if the app is in the foreground (or a data message is sent) you can completely use your own logic to customise the display. You can also always customise the icon if sending the message from the HTTP/XMPP APIs.

Acording to your first code snipet seems ok, but I've got similar behavior caused by bad programing. Have you checked the "options" variable is not null before the put call?

I'm using Struts2 (2.3.3) webapp and use a HashMap for displaying results. When is executed (in a class initialized by an Action class) :

Got this error:

Turns out that npm was installed in the wrong directory so I had to change the “npm config prefix” by running this code:

npm config set prefix /usr/local

Then I reinstalled gulp globally (with the -g param) and it worked properly.

This article is where I found the solution: http://webbb.be/blog/command-not-found-node-npm

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

I know this isn't a 'replacement' WebBrowser control, but I was having some awful rendering issues whilst showing a page that was using BootStrap 3+ for layout etc, and then I found a post that suggested I use the following. Apparently, it's specific to IE and tells it to use the latest variation found on the client machine for rendering (so it won't use IE7, which I believe is the default).

So just put:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

somewhere in the head part of your document.

Obviously, if it's not your document, this won't help - though I personally consider it to be a security hole if you're reading pages not created by yourself through the WebBrowser control - why not just use a web browser!

I was poking around stuff like: int cc = 'cc'; It happens that it's basically a byte-wise copy to an integer. Hence the way to look at it is that 'cc' which is basically 2 c's are copied to lower 2 bytes of the integer cc. If you are looking for a trivia, then

printf("%d %d", 'c', 'cc'); would give:

99 25443

that's because 25443 = 99 + 256*99

So 'cc' is a multi-character constant and not a string.

One way would be to inherit a new class,EntryWithSet, and defining set method that makes use of delete and insert methods of the Entry class objects:

try:                        # In order to be able to import tkinter for
    import tkinter as tk    # either in python 2 or in python 3
except ImportError:
    import Tkinter as tk


class EntryWithSet(tk.Entry):
    """
    A subclass to Entry that has a set method for setting its text to
    a given string, much like a Variable class.
    """

    def __init__(self, master, *args, **kwargs):
        tk.Entry.__init__(self, master, *args, **kwargs)


    def set(self, text_string):
        """
        Sets the object's text to text_string.
        """

        self.delete('0', 'end')
        self.insert('0', text_string)


def on_button_click():
    import random, string
    rand_str = ''.join(random.choice(string.ascii_letters) for _ in range(19))
    entry.set(rand_str)


if __name__ == '__main__':
    root = tk.Tk()
    entry = EntryWithSet(root)
    entry.pack()
    tk.Button(root, text="Set", command=on_button_click).pack()
    tk.mainloop()

use this way in xml

   <TextView
        android:id="@+id/myText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Time is precious, so love now."
        android:gravity="center"
        android:textSize="30dp"
        android:textColor="#fff"
        />

NOT IN returns 0 records when compared against an unknown value

Since NULL is an unknown, a NOT IN query containing a NULL or NULLs in the list of possible values will always return 0 records since there is no way to be sure that the NULL value is not the value being tested.

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

There is a class in iOS 4 which supports sending messages with body and recipents from your application. It works the same as sending mail. You can find the documentation here: link text

types is optional

If you don't know what backend is , you can read this: https://matplotlib.org/tutorials/introductory/usage.html#backends

Some people use matplotlib interactively from the python shell and have plotting windows pop up when they type commands. Some people run Jupyter notebooks and draw inline plots for quick data analysis. Others embed matplotlib into graphical user interfaces like wxpython or pygtk to build rich applications. Some people use matplotlib in batch scripts to generate postscript images from numerical simulations, and still others run web application servers to dynamically serve up graphs. To support all of these use cases, matplotlib can target different outputs, and each of these capabilities is called a backend; the "frontend" is the user facing code, i.e., the plotting code, whereas the "backend" does all the hard work behind-the-scenes to make the figure.

So when you type %matplotlib inline , it activates the inline backend. As discussed in the previous posts :

With this backend, the output of plotting commands is displayed inline within frontends like the Jupyter notebook, directly below the code cell that produced it. The resulting plots will then also be stored in the notebook document.

Try this:

        string searchValue = textBox3.Text;
        int rowIndex = -1;

        dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        try
        {
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                if (row.Cells["peseneli"].Value.ToString().Equals(searchValue))
                {
                    rowIndex = row.Index;
                    dataGridView1.CurrentCell = dataGridView1.Rows[rowIndex].Cells[0];
                    dataGridView1.Rows[dataGridView1.CurrentCell.RowIndex].Selected = true;

                    break;
                }
            }
        }
        catch (Exception exc)
        {
            MessageBox.Show(exc.Message);
        }

You can handle loading the excel file content by writing Java code using Apache POI library (https://poi.apache.org/). The library is developed for working with MS office application data including Excel.

I have recently created the application based on the technology that will help you to load Excel files to the Postgres database. The application is available under http://www.abespalov.com/. The application is tested only for Windows, but should work for Linux as well.

The application automatically creates necessary tables with the same columns as in the Excel files and populate the tables with content. You can export several files in parallel. You can skip the step to convert the files into the CSV format. The application handles the xls and xlsx formats.

Overall application stages are :

1. Load the excel file content. Here is the code depending on file extension:

{

fileExtension = FilenameUtils.getExtension(inputSheetFile.getName());
    if (fileExtension.equalsIgnoreCase("xlsx")) {
        workbook = createWorkbook(openOPCPackage(inputSheetFile));
    } else {
        workbook =     
        createWorkbook(openNPOIFSFileSystemPackage(inputSheetFile));
    }

sheet = workbook.getSheetAt(0);

}

2. Establish Postgres JDBC connection
3. Create a Postgres table
4. Iterate over the sheet and inset rows into the table. Here is a piece of Java code :

{

Iterator<Row> rowIterator = InitInputFilesImpl.sheet.rowIterator();

//skip a header
if (rowIterator.hasNext()) {
    rowIterator.next();
}
while (rowIterator.hasNext()) {
    Row row = (Row) rowIterator.next();
    // inserting rows
}  

}

Here you can find all Java code for the application created for exporting excel to Postgres (https://github.com/palych-piter/Excel2DB).

Use tee --append or tee -a.

echo 'deb blah ... blah' | sudo tee -a /etc/apt/sources.list

Make sure to avoid quotes inside quotes.

To avoid printing data back to the console, redirect the output to /dev/null.

echo 'deb blah ... blah' | sudo tee -a /etc/apt/sources.list > /dev/null

Remember about the (-a/--append) flag! Just tee works like > and will overwrite your file. tee -a works like >> and will write at the end of the file.

class MyClass {
    private $firstField;
    private $secondField;
    private $thirdField;

    public function __get( $name ) {
        if( method_exists( $this , $method = ( 'get' . ucfirst( $name  ) ) ) )
            return $this->$method();
        else
            throw new Exception( 'Can\'t get property ' . $name );
    }

    public function __set( $name , $value ) {
        if( method_exists( $this , $method = ( 'set' . ucfirst( $name  ) ) ) )
            return $this->$method( $value );
        else
            throw new Exception( 'Can\'t set property ' . $name );
    }

    public function __isset( $name )
    {
        return method_exists( $this , 'get' . ucfirst( $name  ) ) 
            || method_exists( $this , 'set' . ucfirst( $name  ) );
    }

    public function getFirstField() {
        return $this->firstField;
    }

    protected function setFirstField($x) {
        $this->firstField = $x;
    }

    private function getSecondField() {
        return $this->secondField;
    }
}

$obj = new MyClass();

echo $obj->firstField; // works
$obj->firstField = 'value'; // works

echo $obj->getFirstField(); // works
$obj->setFirstField( 'value' ); // not works, method is protected

echo $obj->secondField; // works
echo $obj->getSecondField(); // not works, method is private

$obj->secondField = 'value'; // not works, setter not exists

echo $obj->thirdField; // not works, property not exists

isset( $obj->firstField ); // returns true
isset( $obj->secondField ); // returns true
isset( $obj->thirdField ); // returns false

Ready!

Quoted from this post:

The question is about how to make CTRL+SHIFT+U work in Visual Studio Code. Here is how to do it. (Version 1.8.1 or above). You can also choose a different key combination.

File-> Preferences -> Keyboard Shortcuts.

An editor will appear with keybindings.json file. Place the following JSON in there and save.

[
 {
    "key": "ctrl+shift+u",
    "command": "editor.action.transformToUppercase",
    "when": "editorTextFocus"
 },
 {
    "key": "ctrl+shift+l",
    "command": "editor.action.transformToLowercase",
    "when": "editorTextFocus"
 }
]

Now CTRL+SHIFT+U will capitalise selected text, even if multi line. In the same way, CTRL+SHIFT+L will make selected text lowercase.

These commands are built into VS Code, and no extensions are required to make them work.

edit: This only applies if you are in control of the MySQL server... if you're not take a look at Mysql password hashing method old vs new

First check with the SQL query

SHOW VARIABLES LIKE 'old_passwords'

(in the MySQL command line client, HeidiSQL or whatever front end you like) whether the server is set to use the old password schema by default. If this returns old_passwords,Off you just happen to have old password entries in the user table. The MySQL server will use the old authentication routine for these accounts. You can simply set a new password for the account and the new routine will be used.

You can check which routine will be used by taking a look at the mysql.user table (with an account that has access to that table)

SELECT `User`, `Host`, Length(`Password`) FROM mysql.user

This will return 16 for accounts with old passwords and 41 for accounts with new passwords (and 0 for accounts with no password at all, you might want to take care of those as well).
Either use the user management tools of the MySQL front end (if there are any) or

SET PASSWORD FOR 'User'@'Host'=PASSWORD('yourpassword');
FLUSH Privileges;

(replace User and Host with the values you got from the previous query.) Then check the length of the password again. It should be 41 now and your client (e.g. mysqlnd) should be able to connect to the server.

see also the MySQL documentation: * http://dev.mysql.com/doc/refman/5.0/en/old-client.html
* http://dev.mysql.com/doc/refman/5.0/en/password-hashing.html
* http://dev.mysql.com/doc/refman/5.0/en/set-password.html

The resolution for this problem is copying the three xcode/project files in the directory and then creating new directory (Whereever else) and then paste the three files/directories.

I found the answer in the official website

$ vi ~/.profile

# add the following line
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

And now restart the terminal or type source !$ (equivalent to source ~/.profile)

IPython comes with some automatic reloading magic:

%load_ext autoreload
%autoreload 2

It will reload all changed modules every time before executing a new line. The way this works is slightly different than dreload. Some caveats apply, type %autoreload? to see what can go wrong.

If you want to always enable this settings, modify your IPython configuration file ~/.ipython/profile_default/ipython_config.py[1] and appending:

c.InteractiveShellApp.extensions = ['autoreload']     
c.InteractiveShellApp.exec_lines = ['%autoreload 2']

Credit to @Kos via a comment below.

[1] If you don't have the file ~/.ipython/profile_default/ipython_config.py, you need to call ipython profile create first. Or the file may be located at $IPYTHONDIR.

SELECT text 
FROM all_source
where name = 'FGETALGOGROUPKEY'
order by line

alternatively:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY')
from dual;

Note the guidelines for performing work on a UI thread, collected on my blog:

• Don't block the UI thread for more than 50ms at a time.
• You can schedule ~100 continuations on the UI thread per second; 1000 is too much.

There are two techniques you should use:

1) Use ConfigureAwait(false) when you can.

E.g., await MyAsync().ConfigureAwait(false); instead of await MyAsync();.

ConfigureAwait(false) tells the await that you do not need to resume on the current context (in this case, "on the current context" means "on the UI thread"). However, for the rest of that async method (after the ConfigureAwait), you cannot do anything that assumes you're in the current context (e.g., update UI elements).

For more information, see my MSDN article Best Practices in Asynchronous Programming.

2) Use Task.Run to call CPU-bound methods.

You should use Task.Run, but not within any code you want to be reusable (i.e., library code). So you use Task.Run to call the method, not as part of the implementation of the method.

So purely CPU-bound work would look like this:

// Documentation: This method is CPU-bound.
void DoWork();

Which you would call using Task.Run:

await Task.Run(() => DoWork());

Methods that are a mixture of CPU-bound and I/O-bound should have an Async signature with documentation pointing out their CPU-bound nature:

// Documentation: This method is CPU-bound.
Task DoWorkAsync();

Which you would also call using Task.Run (since it is partially CPU-bound):

await Task.Run(() => DoWorkAsync());

This is an older question, but if you simply want to run the simulator from the Xcode 4.5 UI, you can do: Xcode > Open Developer Tool > iOS Simulator.

For both python3 and python2 you can use pyautogui (pip install pyautogui)

from pyautogui import press, typewrite, hotkey

press('a')
typewrite('quick brown fox')
hotkey('ctrl', 'w')

It's also crossplatform with Windows, OSX, and Ubuntu LTS.

The solution is very simple, but took me about 2 hours and half the hair on my head to find it.

Simply wrap your content with a (redundant) div that has display: none and Bob is your uncle.

<div style="display: none">
    <div id="content-div">Some content here</div>
</div>

Voila

In my opinion the best solution.

- (void)didMoveToParentViewController:(UIViewController *)parent
{
    if (![parent isEqual:self.parentViewController]) {
         NSLog(@"Back pressed");
    }
}

But it only works with iOS5+

Use Jquery Method unique.

var UniqueNames= $.unique(data.DATA.map(function (d) {return d.name;}));

alert($.unique(names));

JSFiddle

In case you have ufw enabled, remember add ftp:

> sudo ufw allow ftp

It took me 2 days to realise that I enabled ufw.

In my case I simply forget to add in my fragment mRecyclerView.setAdapter(adapter)

To "call" means to make a reference in your code to a function that is written elsewhere. This function "call" can be made to the standard Python library (stuff that comes installed with Python), third-party libraries (stuff other people wrote that you want to use), or your own code (stuff you wrote). For example:

#!/usr/env python

import os

def foo():
    return "hello world"

print os.getlogin()
print foo()

I created a function called "foo" and called it later on with that print statement. I imported the standard "os" Python library then I called the "getlogin" function within that library.

Quick solution I found was inside the pgAdmin program for windows. Under Tools menu there is a "Query Tool". Inside the Query Tool there is a Graphical Query Builder that can quickly show the database tables details. Good for a basic view

Try $("#divVideo video")[0].load(); after you changed the src attribute.

Another reason this can happen:

The component you are using formControl in is not declared in a module that imports the ReactiveFormsModule.

So check the module that declares the component that throws this error.

The rules of locating classes in an archive file is that the location of the file's package declaration and the location of the file within the archive have to match. Since your class is located in WEB-INF/classes, it thinks the class is not valid to run in the current context.

The only way you can do what you're asking is to repackage the war so the .class file resides in the mypackage directory in the root of the archive rather than the WEB-INF/classes directory. However, if you do that you won't be able to access the file from any of your web classes anymore.

If you want to reuse this class in both the war and outside from the java command line, consider building an executable jar you can run from the command line, then putting that jar in the war file's WEB-INF/lib directory.

Oh my. This is actually so simple!

grouped = df3.groupby(level=0)
df4 = grouped.last()

Follow up edit 2013-10-29 In the case where I have a fairly complex MultiIndex, I think I prefer the groupby approach. Here's simple example for posterity:

import numpy as np
import pandas

# fake index
idx = pandas.MultiIndex.from_tuples([('a', letter) for letter in list('abcde')])

# random data + naming the index levels
df1 = pandas.DataFrame(np.random.normal(size=(5,2)), index=idx, columns=['colA', 'colB'])
df1.index.names = ['iA', 'iB']

# artificially append some duplicate data
df1 = df1.append(df1.select(lambda idx: idx[1] in ['c', 'e']))
df1
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233
#   c   0.275806 -0.078871  # <--- dup 1
#   e  -0.066680  0.607233  # <--- dup 2

and here's the important part

# group the data, using df1.index.names tells pandas to look at the entire index
groups = df1.groupby(level=df1.index.names)  
groups.last() # or .first()
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233

either bin\Iris.exe (no leading slash - because that means start right from the root)
or \Program\bin\Iris.exe (full path)

Another way to accomplish this in a functional component, is to use useEffect and useFunction, like this:

import React, { useEffect } from 'react';

const App = () => {


  useEffect(() => {
    const handleEsc = (event) => {
       if (event.keyCode === 27) {
        console.log('Close')
      }
    };
    window.addEventListener('keydown', handleEsc);

    return () => {
      window.removeEventListener('keydown', handleEsc);
    };
  }, []);

  return(<p>Press ESC to console log "Close"</p>);
}

Instead of console.log, you can use useState to trigger something.

You Can use this -

Suppose we have a list, l = [1,2,3,4,5]

We want to delete last two items in a single statement

del l[3:]

We have output:

l = [1,2,3]

Keep it Simple

For a complete overview of your Spark environment and configuration I found the following code snippets useful:

SparkContext:

for item in sorted(sc._conf.getAll()): print(item)

Hadoop Configuration:

hadoopConf = {}
iterator = sc._jsc.hadoopConfiguration().iterator()
while iterator.hasNext():
    prop = iterator.next()
    hadoopConf[prop.getKey()] = prop.getValue()
for item in sorted(hadoopConf.items()): print(item)

Environment variables:

import os
for item in sorted(os.environ.items()): print(item)

There is charts4j which is a charts and graphs API. It enables developers to programmatically create the charts available in the Google Chart API through a straightforward and intuitive Java API.

Disclaimer: I wrote charts4j. We will be doing another major release in the next few weeks.

Try to delete the maven folder at ~/.m2/repository/org/apache/maven and build your project again to force the maven libraries be downloaded. This worked for me the last time I faced this java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFilteringException.

Well, other languages have reserved words that are instances of types. Python, for instance:

>>> None = 5
  File "<stdin>", line 1
SyntaxError: assignment to None
>>> type(None)
<type 'NoneType'>

This is actually a fairly close comparison because None is typically used for something that hasn't been intialized, but at the same time comparisons such as None == 0 are false.

On the other hand, in plain C, NULL == 0 would return true IIRC because NULL is just a macro returning 0, which is always an invalid address (AFAIK).

Try the following query:

DECLARE @item VARCHAR(MAX) = 'LD-23DSP-1430'

SELECT
SUBSTRING( @item, 0, CHARINDEX('-', @item)) ,
SUBSTRING(
               SUBSTRING( @item, CHARINDEX('-', @item)+1,LEN(@ITEM)) ,
               0 ,
               CHARINDEX('-', SUBSTRING( @item, CHARINDEX('-', @item)+1,LEN(@ITEM)))
              ),
REVERSE(SUBSTRING( REVERSE(@ITEM), 0, CHARINDEX('-', REVERSE(@ITEM))))

I wrote this "C" function, because NSTask is obnoxious..

NSString * runCommand(NSString* c) {

    NSString* outP; FILE *read_fp;  char buffer[BUFSIZ + 1];
    int chars_read; memset(buffer, '\0', sizeof(buffer));
    read_fp = popen(c.UTF8String, "r");
    if (read_fp != NULL) {
        chars_read = fread(buffer, sizeof(char), BUFSIZ, read_fp);
        if (chars_read > 0) outP = $UTF8(buffer);
        pclose(read_fp);
    }   
    return outP;
}

NSLog(@"%@", runCommand(@"ls -la /")); 

total 16751

oh, and for the sake of being complete / unambiguous…

#define $UTF8(A) ((NSString*)[NSS stringWithUTF8String:A])

Years later, C is still a bewildering mess, to me.. and with little faith in my ability to correct my gross shortcomings above - the only olive branch I offer is a rezhuzhed version of @inket's answer that is barest of bones, for my fellow purists / verbosity-haters...

id _system(id cmd) { 
   return !cmd ? nil : ({ NSPipe* pipe; NSTask * task;
  [task = NSTask.new setValuesForKeysWithDictionary:

        @"arguments" : @[@"-c", cmd],
   @"standardOutput" : pipe = NSPipe.pipe}]; [task launch];
  [NSString.alloc initWithData:
     pipe.fileHandleForReading.readDataToEndOfFile
                      encoding:NSUTF8StringEncoding]; });
}

There is only one way from what I am aware.

Have 2 images, first a jpeg with first frame(or whatever you want) of the gif and the actual gif.

Load the page with the jpeg in place and on mouse over replace the jpeg with the gif. You can preload the gifs if you want or if they are of big size show a loading while the gif is loading and then replace the jpeg with it.

If you whant it to bi linear as in have the gif play on mouse over, stop it on mouse out and then resume play from the frame you stopped, then this cannot be done with javascript+gif combo.

The top answer works in the case that you want to examine the state immediately prior to the failed command.

However, the question asks how to examine the state of the failed container itself. In my situation, the failed command is a build that takes several hours, so rewinding prior to the failed command and running it again takes a long time and is not very helpful.

The solution here is to find the container that failed:

$ docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                          PORTS               NAMES
6934ada98de6        42e0228751b3        "/bin/sh -c './utils/"   24 minutes ago      Exited (1) About a minute ago                       sleepy_bell

Commit it to an image:

$ docker commit 6934ada98de6
sha256:7015687976a478e0e94b60fa496d319cdf4ec847bcd612aecf869a72336e6b83

And then run the image [if necessary, running bash]:

$ docker run -it 7015687976a4 [bash -il]

Now you are actually looking at the state of the build at the time that it failed, instead of at the time before running the command that caused the failure.

Further to @Udi post this is what the script tried to do, but did not work with me.

I had to the set the following in the PATH nothing else.

C:\Users\hUTBER\AppData\Local\Programs\Python\Python35
C:\Users\hUTBER\AppData\Local\Programs\Python\Python35\Scripts

Were mine and now python works in the cmd

First check HOME setting, then change HOME and HOMEDRIVE to a existing dir.

c:\git>set HOME
HOME=U:\
HOMEDRIVE=U:
HOMEPATH=\

then change HOME and HOMEDRIVE by

set HOME=c:\tmp
set HOMEDRIVE=C:

There are many examples and also of different types for logging. Take a look at the java.util.logging package.

Example code:

import java.util.logging.Logger;

public class Main {

  private static Logger LOGGER = Logger.getLogger("InfoLogging");

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

Without hard-coding the class name:

import java.util.logging.Logger;

public class Main {
  private static final Logger LOGGER = Logger.getLogger(
    Thread.currentThread().getStackTrace()[0].getClassName() );

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

select inet_server_addr(); gives you the ip address of the server.

You don't need to use arrays.

JSON values can be arrays, objects, or primitives (numbers or strings).

You can write JSON like this:

{ 
    "stuff": {
        "onetype": [
            {"id":1,"name":"John Doe"},
            {"id":2,"name":"Don Joeh"}
        ],
        "othertype": {"id":2,"company":"ACME"}
    }, 
    "otherstuff": {
        "thing": [[1,42],[2,2]]
     }
}

You can use it like this:

obj.stuff.onetype[0].id
obj.stuff.othertype.id
obj.otherstuff.thing[0][1]  //thing is a nested array or a 2-by-2 matrix.
                            //I'm not sure whether you intended to do that.

This is badly formed HTML. You need to either have a single id or space separated classes. Either way if you're new I'd look into jQuery.

<div id="sub1">some text</div>

or

<div class="sub1 sub2 sub3">some text</div>

If you had the following HTML:

<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Some welcome message</div>

jQuery

$(document).ready(function() {
    $('#sub1').hover(
      function() { $('#welcome').show(); },
      function() { $('#welcome').hide(); }
    );
});

Javascript

you'd probably want to include the events on your html:

<div id="sub1" onmouseover="showWelcome();" onmouseout="hideWelcome();">some text</div>

then your javascript would have these two functions

function showWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'block';
}

function hideWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'none';
}

Please note: this javascript doesn't take cross browser issues into consideration. for this you'd need to elaborate on your code, just another reason to use jquery.

Use xsd:include to bring in an XSD from the same or no namespace.

Use xsd:import to bring in an XSD from a different namespace.

mongod --dbpath "c://data/db"

run the above code, this will start the server.

Thanks to @Pax Diablo, @bvmou and @Arachnid for the suggestion of using full datetimes throughout. If I have to accept datetime.time objects from an external source, then this seems to be an alternative add_secs_to_time() function:

def add_secs_to_time(timeval, secs_to_add):
    dummy_date = datetime.date(1, 1, 1)
    full_datetime = datetime.datetime.combine(dummy_date, timeval)
    added_datetime = full_datetime + datetime.timedelta(seconds=secs_to_add)
    return added_datetime.time()

This verbose code can be compressed to this one-liner:

(datetime.datetime.combine(datetime.date(1, 1, 1), timeval) + datetime.timedelta(seconds=secs_to_add)).time()

but I think I'd want to wrap that up in a function for code clarity anyway.

Clone Temporary Table Structure to New Physical Table in SQL Server

we will see how to Clone Temporary Table Structure to New Physical Table in SQL Server.This is applicable for both Azure SQL db and on-premises.

Demo SQL Script

IF OBJECT_ID('TempDB..#TempTable') IS NOT NULL
    DROP TABLE #TempTable;

SELECT 1 AS ID,'Arul' AS Names
INTO
#TempTable;

SELECT * FROM #TempTable;

METHOD 1

SELECT * INTO TempTable1 FROM #TempTable WHERE 1=0;

EXEC SP_HELP TempTable1;

METHOD 2

SELECT TOP 0 * INTO TempTable1 FROM #TempTable;

EXEC SP_HELP TempTable1;

personally i'd rather go with tcpdf which is an ehnanced and mantained version of fpdf.

The Ctrl+Alt+Down / Ctrl+Alt+Up flips my screen so I overrode that in the Eclipse shortcuts via Window => Preferences => General => Keys. Search for "dupl" to find the Duplicate Lines command. I overrode the default and chose Ctrl+Shift+D. For me, that's easy to remember just like Ctrl+D to delete lines

According to http://caniuse.com/#feat=flexbox:

"IE10 and IE11 default values for flex are 0 0 auto rather than 0 1 auto, as per the draft spec, as of September 2013"

So in plain words, if somewhere in your CSS you have something like this: flex:1 , that is not translated the same way in all browsers. Try changing it to 1 0 0 and I believe you will immediately see that it -kinda- works.

The problem is that this solution will probably mess up firefox, but then you can use some hacks to target only Mozilla and change it back:

@-moz-document url-prefix() {
 #flexible-content{
      flex: 1;
    }
}

Since flexbox is a W3C Candidate and not official, browsers tend to give different results, but I guess that will change in the immediate future.

If someone has a better answer I would like to know!

Tested only on Visual Studio 2010.

Place your cursor within the (), press Ctrl+K, then P.

Now navigate by pressing the  ?  / ?   arrow keys.

You cannot use next() in this scenario, if you look at the documentation it says:
Next() Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling that matches the selector.

so if the second DIV was in the same TD then you could code:

// Won't work in your case
$(obj).next().filter('.class');

$(obj).parents('table').find('.class')

$ pip install django-better-choices

For those who are interested, I have created django-better-choices library, that provides a nice interface to work with Django choices for Python 3.7+. It supports custom parameters, lots of useful features and is very IDE friendly.

You can define your choices as a class:

from django_better_choices import Choices


class PAGE_STATUS(Choices):
    CREATED = 'Created'
    PENDING = Choices.Value('Pending', help_text='This set status to pending')
    ON_HOLD = Choices.Value('On Hold', value='custom_on_hold')

    VALID = Choices.Subset('CREATED', 'ON_HOLD')

    class INTERNAL_STATUS(Choices):
        REVIEW = 'On Review'

    @classmethod
    def get_help_text(cls):
        return tuple(
            value.help_text
            for value in cls.values()
            if hasattr(value, 'help_text')
        )

Then do the following operations and much much more:

print( PAGE_STATUS.CREATED )                # 'created'
print( PAGE_STATUS.ON_HOLD )                # 'custom_on_hold'
print( PAGE_STATUS.PENDING.display )        # 'Pending'
print( PAGE_STATUS.PENDING.help_text )      # 'This set status to pending'

'custom_on_hold' in PAGE_STATUS.VALID       # True
PAGE_STATUS.CREATED in PAGE_STATUS.VALID    # True

PAGE_STATUS.extract('CREATED', 'ON_HOLD')   # ~= PAGE_STATUS.VALID

for value, display in PAGE_STATUS:
    print( value, display )

PAGE_STATUS.get_help_text()
PAGE_STATUS.VALID.get_help_text()

And of course, it is fully supported by Django and Django Migrations:

class Page(models.Model):
    status = models.CharField(choices=PAGE_STATUS, default=PAGE_STATUS.CREATED)

Full documentation here: https://pypi.org/project/django-better-choices/

Many of the other answers are all well but if you want an informational tooltip instead of a fullblown window then do this: after enabling it using @Ahmad's answer then click on the little pin on the upper right corner:

After this the method information will appear on a tooltip like almost every other mainstream IDE.

None of solutions on this page works correctly and universally for all levels and long (wrapped) paragraphs. It’s really tricky to achieve a consistent indentation due to variable size of marker (1., 1.2, 1.10, 1.10.5, …); it can’t be just “faked,” not even with a precomputed margin/padding for each possible indentation level.

I finally figured out a solution that actually works and doesn’t need any JavaScript.

It’s tested on Firefox 32, Chromium 37, IE 9 and Android Browser. Doesn't work on IE 7 and previous.

CSS:

ol {
  list-style-type: none;
  counter-reset: item;
  margin: 0;
  padding: 0;
}

ol > li {
  display: table;
  counter-increment: item;
  margin-bottom: 0.6em;
}

ol > li:before {
  content: counters(item, ".") ". ";
  display: table-cell;
  padding-right: 0.6em;    
}

li ol > li {
  margin: 0;
}

li ol > li:before {
  content: counters(item, ".") " ";
}

Example:

Try it on JSFiddle, fork it on Gist.

I would say that while both are correct mathematically, implementation-wise, first one is better. When computing softmax, the intermediate values may become very large. Dividing two large numbers can be numerically unstable. These notes (from Stanford) mention a normalization trick which is essentially what you are doing.

I have used

tabindex="{{isEditedParaOrder?-1:0}}" 
[style.pointer-events]="isEditedParaOrder ?'none':'auto'" 

in my anchor tag so that they can not move to anchor tag by using tab to use "enter" key and also pointer itself we are setting to 'none' based on property 'isEditedParaO rder' whi

In my case DialogFragment occupied full activity size like a Fragment. The DialogFragment was based on XML-layout, not AlertDialog. My mistake was adding the dialog fragment to FragmentManager as a usual fragment:

fragmentManager?.beginTransaction()?.run {
    replace(R.id.container, MyDialogFragment.newInstance(), MyDialogFragment.TAG)
    addToBackStack(MyDialogFragment.TAG)
}?.commitAllowingStateLoss()

Instead I need to show the dialog fragment:

val dialogFragment = MyDialogFragment.newInstance()
fragmentManager?.let { dialogFragment.show(it, MyDialogFragment.TAG) }

After some editing (I have ViewPager2 in the layout) the dialog fragment became too narrow:

I used the solution of N1hk:

override fun onActivityCreated(savedInstanceState: Bundle?) {
    super.onActivityCreated(savedInstanceState)

    dialog?.window?.attributes?.width = ViewGroup.LayoutParams.MATCH_PARENT
    dialog?.window?.attributes?.height = ViewGroup.LayoutParams.MATCH_PARENT
}

Now it has defined width and height, not full activity size.

I want to say about onCreateView and onCreateDialog. If you have a dialog fragment based on layout, you can use any of these 2 methods.

1. If you use onCreateView, then you should use onActivityCreated to set width.

2. If you use onCreateDialog instead of onCreateView, you can set parameters there. onActivityCreated won't be needed.

   override fun onCreateDialog(savedInstanceState: Bundle?): Dialog { super.onCreateDialog(savedInstanceState)

    val view = activity?.layoutInflater?.inflate(R.layout.your_layout, null)
   
    val dialogBuilder = MaterialAlertDialogBuilder(context!!).apply { // Or AlertDialog.Builder(context!!).apply
        setView(view)
        // setCancelable(false)
    }
   
    view.text_view.text = "Some text"
   
    val dialog = dialogBuilder.create()
    // You can access dialog.window here, if needed.
   
    return dialog
   

   }

If you want to only trigger validation when the input looses focus you can use onBlur

Trivia: React <17 listens to blur event and >=17 listens to focusout event.

On the one hand you could use sp_executesql:

exec sp_executesql N'select @rowcount=count(*) from anytable', 
                    N'@rowcount int output', @rowcount output;

On the other hand you could use a temporary table:

declare @result table ([rowcount] int);
insert into @result ([rowcount])
exec (N'select count(*) from anytable');
declare @rowcount int = (select top (1) [rowcount] from @result);

For some reason no one has mentioned the fact that the bashrc needs to be re-sourced after editing. You can either log out and log back in (like mentioned above) but you can also use the commands: source ~/.bashrc or . ~/.bashrc.

When you #include a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal variable is defined in the source so it will work no matter how it's declared.

Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.

Shift-Alt-J is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.

Invoking the shortcut on a class, method or field declaration will create a Javadoc template:

public int doAction(int i) {
    return i;
}

Pressing Shift-Alt-J on the method declaration gives:

/**
 * @param i
 * @return
 */
public int doAction(int i) {
    return i;
}

public class Factorial {
public static void main(String[] args) {
   int n = 7;
   int result = 1;
   for (int i = 1; i <= n; i++) {
       result = result * i;
   }
   System.out.println("The factorial of 7 is " + result);
}
}

This library makes it simple.

Just Call:

PickImageDialog.on(MainActivity.this, new PickSetup(BuildConfig.APPLICATION_ID));

Then make your Activity implement IPickResult and override this below method.

@Override
public void onPickResult(PickResult r) {
    if (r.getError() == null) {
        imageView.setImageBitmap(r.getBitmap());

        //or

        imageView.setImageURI(r.getUri());
    } else {
        //Handle possible errors
        //TODO: do what you have to do with r.getError();
    }
}

The best way to get number of rows from resultset is using count function query for database access and then rs.getInt(1) method to get number of rows. from my code look it:

    String query = "SELECT COUNT() FROM table";
ResultSet rs = new DatabaseConnection().selectData(query);
rs.getInt(1);

this will return int value number of rows fetched from database. Here DatabaseConnection().selectData() is my code for accessing database. I was also stuck here but then solved...

Adding to Eric's answer, you can also configure this in the csproj file:

<ItemGroup>
    <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
      <_Parameter1>MyTests</_Parameter1>
    </AssemblyAttribute>
</ItemGroup>

Or if you have one test project per project to be tested, you could do something like this in your Directory.Build.props file:

<ItemGroup>
    <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
      <_Parameter1>$(MSBuildProjectName).Test</_Parameter1>
    </AssemblyAttribute>
</ItemGroup>

See: https://stackoverflow.com/a/49978185/1678053
Example: https://github.com/gldraphael/evlog/blob/master/Directory.Build.props#L5-L12

I had an old Excel database with "human-readable" dates, like 2010.03.28 20:12:30 Theese dates were in UTC+1 (CET) and needed to convert it to epoch time.

I used the =(A4-DATE(1970;1;1))*86400-3600 formula to convert the dates to epoch time from the A column to B column values. Check your timezone offset and make a math with it. 1 hour is 3600 seconds.

The only thing why i write here an anwser, you can see that this topic is more than 5 years old is that i use the new Excel versions and also red posts in this topic, but they're incorrect. The DATE(1970;1;1). Here the 1970 and the January needs to be separated with ; and not with ,

If you're also experiencing this issue, hope it helps you. Have a nice day :)

If you need to do many append operations to build a large string, you can use StringIO or cStringIO. The interface is like a file. ie: you write to append text to it.

If you're just appending two strings then just use +.

If you have php installed on your local machine try:

$ php -a
Interactive shell

php > phpinfo();

$gender = $_POST['gender'];
echo $gender;  

it will echoes the selected value.

For iOS 8 above it's really simple:

override func viewDidLoad() {  
    super.viewDidLoad()

    self.tableView.estimatedRowHeight = 80
    self.tableView.rowHeight = UITableView.automaticDimension
}

or

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableView.automaticDimension
}

But for iOS 7, the key is calculate the height after autolayout:

func calculateHeightForConfiguredSizingCell(cell: GSTableViewCell) -> CGFloat {
    cell.setNeedsLayout()
    cell.layoutIfNeeded()
    let height = cell.contentView.systemLayoutSizeFittingSize(UILayoutFittingExpandedSize).height + 1.0
    return height
}

Important

• If multiple lines labels, don't forget set the numberOfLines to 0.

• Don't forget label.preferredMaxLayoutWidth = CGRectGetWidth(tableView.bounds)

The full example code is here.

The below code assumes that the variable 'str' contains your http://.... string. It checks to see if it is https and if true does nothing. However if it is http it replaces http with https.

if (str.indexOf('https') === -1) {
  str = str.replace('http', 'https')
}

Try this:

function funcName() {
    alert("test");
}

var run = setInterval(funcName, 10000)

Since it's a POD struct, you could always memset it to 0 - this might be the easiest way to get the fields initialized (assuming that is appropriate).

If anyone is interested in a no-brainer solution for drawing an image in a custom rect in a context:

 func drawImage(image: UIImage, inRect rect: CGRect, context: CGContext!) {

    //flip coords
    let ty: CGFloat = (rect.origin.y + rect.size.height)
    CGContextTranslateCTM(context, 0, ty)
    CGContextScaleCTM(context, 1.0, -1.0)

    //draw image
    let rect__y_zero = CGRect(origin: CGPoint(x: rect.origin.x, y:0), size: rect.size)
    CGContextDrawImage(context, rect__y_zero, image.CGImage)

    //flip back
    CGContextScaleCTM(context, 1.0, -1.0)
    CGContextTranslateCTM(context, 0, -ty)

}

The image will be scaled to fill the rect.

Have a look at: http://www.javaspecialists.eu/archive/Issue068.html and http://www.javaspecialists.eu/archive/Issue105.html

Do the same tests in your environment and check if newer JDK or your Java implementation do some type of string operation better with String or better with StringBuilder.

There is not a program but you can make a batch file and run a command like that :

powershell "start-process 'C:\Program Files (x86)\IIS Express\iisexpress.exe' -workingdirectory 'C:\Program Files (x86)\IIS Express\' -windowstyle Hidden"

The exception can be caught in the async function.

public async void Foo()
{
    try
    {
        var x = await DoSomethingAsync();
        /* Handle the result, but sometimes an exception might be thrown
           For example, DoSomethingAsync get's data from the network
           and the data is invalid... a ProtocolException might be thrown */
    }
    catch (ProtocolException ex)
    {
          /* The exception will be caught here */
    }
}

public void DoFoo()
{
    Foo();
}

I found the answer to this problem here

Just do

mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

You need "src/Hankees.txt"

Your file is in the source folder which is not counted as the working directory.\

Or you can move the file up to the root directory of your project and just use "Hankees.txt"

You cannot "convert" an existing column into an IDENTITY column - you will have to create a new column as INT IDENTITY:

ALTER TABLE ProductInProduct 
ADD NewId INT IDENTITY (1, 1);

Update:

OK, so there is a way of converting an existing column to IDENTITY. If you absolutely need this - check out this response by Martin Smith with all the gory details.

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

As stated in PostgreSQL docs here:

The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.

Code snippet specifically answering your question:

SELECT field1, field2,
  CASE
    WHEN field1>0 THEN field2/field1
    ELSE 0
  END 
  AS field3
FROM test

1.Set the delegate of your textfield:

 textField.delegate = self

2.Implement the method in your view controller :

// MARK: Text field delegate

extension ViewController: UITextFieldDelegate {
    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        return range.location < maxLength (maxLength can be any maximum length you can define)
    }
}

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

"1" + "2" => "12"
"1" + 2   => 3
1 + "2"   => 3
"a" + 2   => type mismatch

This is simply a subtle source of potential bugs and therefore should be avoided. & always means "string concatenation", even if its arguments are non-strings:

"1" & "2" => "12"
"1" &  2  => "12"
 1  & "2" => "12"
 1  &  2  => "12"
"a" &  2  => "a2"

I know this is an older question with a lot of good answers but I'd like to include a one sentence answer:

Treating a derived type as if it were it's base type.

There are plenty of examples above that show this in action, but I feel this is a good concise answer.

We actually have some notification code in our product that uses TLS to send mail if it is available.

You will need to set the Java Mail properties. You only need the TLS one but you might need SSL if your SMTP server uses SSL.

Properties props = new Properties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");  // If you need to authenticate
// Use the following if you need SSL
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

You can then either pass this to a JavaMail Session or any other session instantiator like Session.getDefaultInstance(props).

After trying every answer I could find here and online, I was still getting errors for some missing headers. When trying to compile pyRFR, I was getting errors about stdexcept not being found, which apparently was not installed in /usr/include with the other headers. However, I found where it was hiding in Mojave and added this to the end of my ~/.bash_profile file:

export CPATH=/Library/Developer/CommandLineTools/usr/include/c++/v1

Having done that, I can now compile pyRFR and other C/C++ programs. According to echo | gcc -E -Wp,-v -, gcc was looking in the old location for these headers (without the /c++/v1), but not the new location, so adding that to CFLAGS fixed it.

In regards to multiple arrays in an object. For instance, you want to record modules for different courses

var course = {
    InfoTech:["Information Systems","Internet Programming","Software Eng"],
    BusComm:["Commercial Law","Accounting","Financial Mng"],
    Tourism:["Travel Destination","Travel Services","Customer Mng"]
};
console.log(course.Tourism[1]);
console.log(course.BusComm);
console.log(course.InfoTech);

http://api.jquery.com/eq/

$("#grid_GridHeader").eq(0)

Another better way of doing it:

:LOOP
timeout /T 1 /NOBREAK 
::pause or sleep x seconds also valid
call myLabel
if not ErrorLevel 1 goto :LOOP

This way you can take care of errors too

My favorite no-conflict-friendly construct:

jQuery(function($) {
  // ...
});

Calling jQuery with a function pointer is a shortcut for $(document).ready(...)

Or as we say in coffeescript:

jQuery ($) ->
  # code here

if( [txtMobile.text length] == 0 )
{
    [Utility showAlertWithTitleAndMessage: AMLocalizedString(@"Invalid Mobile No",nil) message: AMLocalizedString(@"Enter valid Mobile Number",nil)];
}

You override __hash__ if you want special hash-semantics, and __cmp__ or __eq__ in order to make your class usable as a key. Objects who compare equal need to have the same hash value.

Python expects __hash__ to return an integer, returning Banana() is not recommended :)

User defined classes have __hash__ by default that calls id(self), as you noted.

There is some extra tips from the documentation.:

Classes which inherit a __hash__() method from a parent class but change the meaning of __cmp__() or __eq__() such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting __hash__ = None in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checking isinstance(obj, collections.Hashable) (unlike classes which define their own __hash__() to explicitly raise TypeError).

Apache PDFBox also works great for me.

Usage with the command line tool:

javar -jar pdfbox-app-2.0.19.jar PDFToImage -quality 1.0  -dpi 150 -prefix out_dir/page -format png

if your sqlite row has a unique id or other equivatent, you can use where clause, like this

update .... where id = {here is your unique row id}

I know it may be repeated answer but for any one want to load list of checkboxes with selectall checkbox into angular form i follow this example: Select all/deselect all checkbox using angular 2+

it work fine but just need to add

[ngModelOptions]="{standalone: true}" 

the final HTML should be like this:

<ul>
    <li><input type="checkbox" [(ngModel)]="selectedAll" (change)="selectAll();"/></li>
    <li *ngFor="let n of names">
    <input type="checkbox" [(ngModel)]="n.selected" (change)="checkIfAllSelected();">{{n.name}}
    </li>
  </ul>

TypeScript

  selectAll() {
    for (var i = 0; i < this.names.length; i++) {
      this.names[i].selected = this.selectedAll;
    }
  }
  checkIfAllSelected() {
    this.selectedAll = this.names.every(function(item:any) {
        return item.selected == true;
      })
  }

hope this help thnx

Check if the scrollable element is already scrolled to the top when trying to scroll up or to the bottom when trying to scroll down and then preventing the default action to stop the entire page from moving.

var touchStartEvent;
$('.scrollable').on({
    touchstart: function(e) {
        touchStartEvent = e;
    },
    touchmove: function(e) {
        if ((e.originalEvent.pageY > touchStartEvent.originalEvent.pageY && this.scrollTop == 0) ||
            (e.originalEvent.pageY < touchStartEvent.originalEvent.pageY && this.scrollTop + this.offsetHeight >= this.scrollHeight))
            e.preventDefault();
    }

At the point you are calling your function, the rest of the page has not rendered and so the element is not in existence at that point. Try calling your function on window.onload maybe. Something like this:

    <script type="text/javascript">
        window.onload = function(){
           var refButton = document.getElementById("btnButton");

            refButton.onclick = function() {
                alert('I am clicked!');
            }
        };
    </script>
</head>
<body>
    <form id="form1">
    <div>
        <input id="btnButton" type="button" value="Click me"/>
    </div>

Be careful using the answer provide by @DevNG. Arrays.asList() returns internal implementation of ArrayList that doesn't implement some useful methods like add(), delete(), etc. If you call them an UnsupportedOperationException will be thrown. In order to get real ArrayList instance you need to write something like this:

List<Video> = new ArrayList<>(Arrays.asList(videoArray));

import java.util.Scanner;

public class Shift {

    public static void main(String[] args) {

        Scanner input = new Scanner (System.in);
        int array[] = new int [5];
        int array1[] = new int [5];
        int i, temp;

        for (i=0; i<5; i++) {
            System.out.printf("Enter array[%d]: \n", i);
            array[i] = input.nextInt(); //Taking input in the array
        }

        System.out.println("\nEntered datas are: \n");
        for (i=0; i<5; i++) {
            System.out.printf("array[%d] = %d\n", i, array[i]); //This will show the data you entered (Not the shifting one)
        }

        temp = array[4]; //We declared the variable "temp" and put the last number of the array there...

        System.out.println("\nAfter Shifting: \n");

        for(i=3; i>=0; i--) {
            array1[i+1] = array[i]; //New array is "array1" & Old array is "array". When array[4] then the value of array[3] will be assigned in it and this goes on..
            array1[0] = temp; //Finally the value of last array which was assigned in temp goes to the first of the new array
        }


        for (i=0; i<5; i++) {
            System.out.printf("array[%d] = %d\n", i, array1[i]);
        }

        input.close();

    }

}

One way to do this is to insert a dummy column with the sums in order to sort:

In [10]: sum_B_over_A = df.groupby('A').sum().B

In [11]: sum_B_over_A
Out[11]: 
A
bar    0.253652
baz   -2.829711
foo    0.551376
Name: B

in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)

In [13]: df
Out[13]: 
     A         B      C  sum_B_over_A
0  foo  1.624345  False      0.551376
1  bar -0.611756   True      0.253652
2  baz -0.528172  False     -2.829711
3  foo -1.072969   True      0.551376
4  bar  0.865408  False      0.253652
5  baz -2.301539   True     -2.829711

In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]: 
     A         B      C   sum_B_over_A
5  baz -2.301539   True      -2.829711
2  baz -0.528172  False      -2.829711
1  bar -0.611756   True       0.253652
4  bar  0.865408  False       0.253652
3  foo -1.072969   True       0.551376
0  foo  1.624345  False       0.551376

and maybe you would drop the dummy row:

In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]: 
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,

css:

header.sticky {
  font-size: 24px;
  line-height: 48px;
  height: 48px;
  background: #efc47D;
  text-align: left;
  padding-left: 20px;
}

JS:

$(window).scroll(function() {
 if ($(this).scrollTop() > 100){  
    $('header').addClass("sticky");
  }
  else{
    $('header').removeClass("sticky");
  }
});

you can use following code.

 StringBuilder strScript = new StringBuilder();
 strScript.Append("alert('your Message goes here');");
 Page.ClientScript.RegisterStartupScript(this.GetType(),"Script", strScript.ToString(), true);

If you just want to execute the shell command in your c program, you could use,

   #include <stdlib.h>

   int system(const char *command);

In your case,

system("pwd");

The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.

What do you mean by this? You should be able to find the mentioned packages in /bin/

sudo find / -executable -name pwd
sudo find / -executable -name echo

See Stack Overflow question sed edit file in place

It would be a good option here, if:

1. To modify a large file, it's impossible to use cat.

2. Install Vim is not allowed or takes too long. My situation is using the MySQL 5.7 image when I want to change the my.cnf file, there is no vim, vi, and Vim install takes too long (China Great Firewall). sed is provided in the image, and it's quite simple. My usage is like

   sed -i /s/testtobechanged/textwanted/g filename

   Use man sed or look for other tutorials for more complex usage.

Another approach when you have many updates would be to use COALESCE:

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = COALESCE(@ABC, [ABC]),
    [ABCD] = COALESCE(@ABCD, [ABCD])

I did

msgbox "TEXT HERE",3,"TITLE HERE"
If Yes=true then
(result)

else
msgbox "Closing..."

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

    jQuery.preloadImage=function(src,onSuccess,onError)
    {
        var img = new Image()
        img.src=src;
        var error=false;
        img.onerror=function(){
            error=true;
            if(onError)onError.call(img);
        }
        if(error==false)    
        setTimeout(function(){
            if(img.height>0&&img.width>0){ 
                if(onSuccess)onSuccess.call(img);
                return img;
            }   else {
                setTimeout(arguments.callee,5);
            }   
        },0);
        return img; 
    }

    jQuery.preloadImages=function(arrayOfImages){
        jQuery.each(arrayOfImages,function(){
            jQuery.preloadImage(this);
        })
    }
 // example   
    jQuery.preloadImage(
        'img/someimage.jpg',
        function(){
            /*complete
            this.width!=0 == true
            */
        },
        function(){
            /*error*/
        }
    )

Like that:

class Zoo {
    AnimalClass: typeof Animal;

    constructor(AnimalClass: typeof Animal ) {
        this.AnimalClass = AnimalClass
        let Hector = new AnimalClass();
    }
}

Or just:

class Zoo {
    constructor(public AnimalClass: typeof Animal ) {
        let Hector = new AnimalClass();
    }
}

typeof Class is the type of the class constructor. It's preferable to the custom constructor type declaration because it processes static class members properly.

Here's the relevant part of TypeScript docs. Search for the typeof. As a part of a TypeScript type annotation, it means "give me the type of the symbol called Animal" which is the type of the class constructor function in our case.

Here is another approach using CSS transform: skew(45deg) to produce the cut corner effect. The shape itself involves three elements (1 real and 2 pseudo-elements) as follows:

• The main container div element has overflow: hidden and produces the left border.
• The :before pseudo-element which is 20% the height of the parent container and has a skew transform applied to it. This element prodcues the border on the top and cut (slanted) border on the right side.
• The :after pseudo-element which is 80% the height of the parent (basically, remaining height) and produces the bottom border, the remaining portion of the right border.

The output produced is responsive, produces a transparent cut at the top and supports transparent backgrounds.

The below is another method to produce the cut corner effect by using linear-gradient background images. A combination of 3 gradient images (given below) is used:

• One linear gradient (angled towards bottom left) to produce the cut corner effect. This gradient has a fixed 25px x 25px size.
• One linear gradient to provide a solid color to the left of the triangle that causes the cut effect. A gradient is used even though it produces a solid color because we can control size, position of background only when images or gradients are used. This gradient is positioned at -25px on X-axis (basically meaning it would end before the place where the cut is present).
• Another gradient similar to the above which again produces a solid color but is positioned at 25px down on the Y-axis (again to leave out the cut area).

The output produced is responsive, produces transparent cut and doesn't require any extra elements (real or pseudo). The drawback is that this approach would work only when the background (fill) is a solid color and it is very difficult to produce borders (but still possible as seen in the snippet).

An alternative way is using raw SQL mode with SQLAlchemy, I use SQLAlchemy 0.9.8, python 2.7, MySQL 5.X, and MySQL-Python as connector, in this case, a tuple is needed. My code listed below:

id_list = [1, 2, 3, 4, 5] # in most case we have an integer list or set
s = text('SELECT id, content FROM myTable WHERE id IN :id_list')
conn = engine.connect() # get a mysql connection
rs = conn.execute(s, id_list=tuple(id_list)).fetchall()

Hope everything works for you.

I found a solution to the problem.

There is an issue reported about gradle build problems, it is not the same, but the solution seems to solve the mergeResourceDebug issues too. (issue here https://code.google.com/p/android/issues/detail?id=56158). In the comments it is stated that the solution is solved in Gradle 0.4.3.

To use Gradle 0.4.3, the build.gradle file needs to be updated manually. (Updating Android Studio does not change the build file)

Here is what I changed In build.gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:0.4.3'
}

Since changing this, I have not seen any more mergeDebugResource issues when running my project. Hope this helps!

Edit: to stay up to date with Gradle you can change the version number to 0.4.+

Use a scalar-valued UDF, not a table-value one, then you can use it in a SELECT as you want.

you can try these:

document.getElementById("RootNode").onclick = function(){/*do something*/};

or

$('#RootNode').click(function(){/*do something*/});

or

$(document).on("click", "#RootNode", function(){/*do something*/});

There is a point for the first two method which is, it matters where in your page DOM, you should put them, the whole DOM should be loaded, to be able to find the, which is usually it gets solved if you wrap them in a window.onload or DOMReady event, like:

//in Vanilla JavaScript
window.addEventListener("load", function(){
     document.getElementById("RootNode").onclick = function(){/*do something*/};
});
//for jQuery
$(document).ready(function(){
    $('#RootNode').click(function(){/*do something*/});
});

the mremote option offers more automation and almost replicates the vmware workstation graphical experience plus major benefits: NO DPI (guest resolution) hassle no copy pose hassle Automation = starting vms and suspending them automatically plus more if you look deeper

In addition to the line.separator property, if you are using java 1.5 or later and the String.format (or other formatting methods) you can use %n as in

Calendar c = ...;
String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY%n", c); 
//Note `%n` at end of line                                  ^^

String s2 = String.format("Use %%n as a platform independent newline.%n"); 
//         %% becomes %        ^^
//                                        and `%n` becomes newline   ^^

See the Java 1.8 API for Formatter for more details.

It's an array of the parameters/arguments (hence args) that you send to the program. For example ping 172.16.0.1 -t -4

These arguments are passed to the program as an array of strings.

Much similar to @Gustavo Baiocchi Costa but offset is being calculated with another intermediate Substring.

int innerTextStart = input.IndexOf("(") + 1;
int innerTextLength = input.Substring(start).IndexOf(")");
string output = input.Substring(innerTextStart, innerTextLength);

I believe this line in the web.config will set the max upload size:

Here is the snippet worked in my case

final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
    buildAlertMessageNoGps();
}

`

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

In order to get CurrentUserId in Asp.net Identity 2.0, at first import Microsoft.AspNet.Identity:

C#:

using Microsoft.AspNet.Identity;

VB.NET:

Imports Microsoft.AspNet.Identity

And then call User.Identity.GetUserId() everywhere you want:

strCurrentUserId = User.Identity.GetUserId()

This method returns current user id as defined datatype for userid in database (the default is String).

        newImageView.contentMode = .scaleAspectFit
        newImageView.isUserInteractionEnabled = true
        let tap = UITapGestureRecognizer(target: self, action: #selector(dismissFullscreenImage))
        newImageView.addGestureRecognizer(tap)
        self.view.addSubview(newImageView)

        self.navigationController?.isNavigationBarHidden = true
        self.tabBarController?.tabBar.isHidden = true

    }

It's Tested And Working Properly

weights.reshape(a, b) will return a new tensor with the same data as weights with size (a, b) as in it copies the data to another part of memory.

weights.resize_(a, b) returns the same tensor with a different shape. However, if the new shape results in fewer elements than the original tensor, some elements will be removed from the tensor (but not from memory). If the new shape results in more elements than the original tensor, new elements will be uninitialized in memory.

weights.view(a, b) will return a new tensor with the same data as weights with size (a, b)

I had this issue for an app that was strongly named then had to change it in order to reference a non-strongly named assembly, so I unchecked 'Sign the assembly' in the project properties Signing section but it still complained. I figured it had to be an artifact somewhere causing the problem since I did everything else correctly and it was just that. I found and removed the line: [assembly: AssemblyKeyFile("yourkeyfilename.snk")] from its assemblyInfo.cs file. Then no build complaints after that.

C has a boolean type: bool (at least for the last 10(!) years)

Include stdbool.h and true/false will work as expected.

I had the same issue and I fixed it as below.

1. install yarn npm install --save-dev yarn
2. install jest-cli npm install --save-dev jest-cli
3. add this to the package.json "jest-coverage": "yarn run jest -- --coverage"

After you write the tests, run the command npm run jest-coverage. This will create a coverage folder in the root directory. /coverage/icov-report/index.html has the HTML view of the code coverage.

In your case you can just do:

    var res = from element in list
              group element by element.F1
                  into groups

hope it will work. Thanks

That's how GROUP BY works. It takes several rows and turns them into one row. Because of this, it has to know what to do with all the combined rows where there have different values for some columns (fields). This is why you have two options for every field you want to SELECT : Either include it in the GROUP BY clause, or use it in an aggregate function so the system knows how you want to combine the field.

For example, let's say you have this table:

Name | OrderNumber
------------------
John | 1
John | 2

If you say GROUP BY Name, how will it know which OrderNumber to show in the result? So you either include OrderNumber in group by, which will result in these two rows. Or, you use an aggregate function to show how to handle the OrderNumbers. For example, MAX(OrderNumber), which means the result is John | 2 or SUM(OrderNumber) which means the result is John | 3.

Using Chrome 15.0.865.0 dev. There's an "Event Listeners" section on the Elements panel:

And an "Event Listeners Breakpoints" on the Scripts panel. Use a Mouse -> click breakpoint and then "step into next function call" while keeping an eye on the call stack to see what userland function handles the event. Ideally, you'd replace the minified version of jQuery with an unminified one so that you don't have to step in all the time, and use step over when possible.

We can use a simple lightweight String.Format string operation library for Typescript.

String.Format():

var id = image.GetId()
String.Format("image_{0}.jpg", id)
output: "image_2db5da20-1c5d-4f1a-8fd4-b41e34c8c5b5.jpg";

String Format for specifiers:

var value = String.Format("{0:L}", "APPLE"); //output "apple"

value = String.Format("{0:U}", "apple"); // output "APPLE"

value = String.Format("{0:d}", "2017-01-23 00:00"); //output "23.01.2017"


value = String.Format("{0:s}", "21.03.2017 22:15:01") //output "2017-03-21T22:15:01"

value = String.Format("{0:n}", 1000000);
//output "1.000.000"

value = String.Format("{0:00}", 1);
//output "01"

String Format for Objects including specifiers:

var fruit = new Fruit();
fruit.type = "apple";
fruit.color = "RED";
fruit.shippingDate = new Date(2018, 1, 1);
fruit.amount = 10000;

String.Format("the {type:U} is {color:L} shipped on {shippingDate:s} with an amount of {amount:n}", fruit);
// output: the APPLE is red shipped on 2018-01-01 with an amount of 10.000

• firewall of the server must be set-up to enable incomming connections on port 3306
• you must have a user in MySQL who is allowed to connect from % (any host) (see manual for details)

The current problem is the first one, but right after you resolve it you will likely get the second one.

I like this one: it - vec.begin(), because to me it clearly says "distance from beginning". With iterators we're used to thinking in terms of arithmetic, so the - sign is the clearest indicator here.

From RMS's GDB debugger tutorial:

prompt > myprogram
Segmentation fault (core dumped)
prompt > gdb myprogram
...
(gdb) core core.pid
...

Make sure your file really is a core image -- check it using file.

As Filburt says; but also note that it's usually better to write

test="not(Count = 'N/A')"

If there's exactly one Count element they mean the same thing, but if there's no Count, or if there are several, then the meanings are different.

Since this answer seems to have become popular, but may be a little cryptic to some readers, let me expand it.

The "=" and "!=" operator in XPath can compare two sets of values. In general, if A and B are sets of values, then "=" returns true if there is any pair of values from A and B that are equal, while "!=" returns true if there is any pair that are unequal.

In the common case where A selects zero-or-one nodes, and B is a constant (say "NA"), this means that not(A = "NA") returns true if A is either absent, or has a value not equal to "NA". By contrast, A != "NA" returns true if A is present and not equal to "NA". Usually you want the "absent" case to be treated as "not equal", which means that not(A = "NA") is the appropriate formulation.

I had a terrible time getting global modules to work. Eventually, I explicitly added C:\Users\yourusername\AppData\Roaming\npm to the PATH variable under System Variables. I also needed to have this variable come before the nodejs path variable in the list.

I am running Windows 10.

just to go File -> Sync Project with Gradle files then it solves problem.

I'm probably late but this worked for me:

1. Open your build.xml file located in your project's directory.
2. Copy and Paste the following code in the main project tag : <target name="build" />

I would take Jon's suggestion and use Ant, since this is a pretty complex task.

However, if you are determined to get it all in one line in the Terminal, on Linux you could use the find command. But I don't recommend this at all, since there's no guarantee that, say, Foo.java will be compiled after Bar.java, even though Foo uses Bar. An example would be:

find . -type f -name "*.java" -exec javac {} \;

If all of your classes haven't been compiled yet, if there's one main harness or driver class (basically the one containing your main method), compiling that main class individually should compile most of project, even if they are in different folders, since Javac will try to the best of its abilities to resolve dependency issues.

Probably your problem is that for Docker that has been installed from default Ubuntu repository, the package name is docker.io

Or package name may be something like docker-ce. Try running

dpkg -l | grep -i docker

to identify what installed package you have

So you need to change package name in commands from https://stackoverflow.com/a/31313851/2340159 to match package name. For example, for docker.io it would be:

sudo apt-get purge -y docker.io
sudo apt-get autoremove -y --purge docker.io
sudo apt-get autoclean

It adds:

The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following command:

sudo rm -rf /var/lib/docker

Remove docker from apparmor.d:

sudo rm /etc/apparmor.d/docker

Remove docker group:

sudo groupdel docker

Put the date in single quotes and move the parenthesis (after the 'yes') to the end:

INSERT INTO custorder 
  VALUES ('Kevin', 'yes' , STR_TO_DATE('1-01-2012', '%d-%m-%Y') ) ;
                        ^                                     ^
---parenthesis removed--|                and added here ------|

But you can always use dates without STR_TO_DATE() function, just use the (Y-m-d) '20120101' or '2012-01-01' format. Check the MySQL docs: Date and Time Literals

INSERT INTO custorder 
  VALUES ('Kevin', 'yes', '2012-01-01') ;

Yes, it's perfectly ok.but avoid doing it without a reason. For example I used it to declare global site rules seperately than indivual pages when my javascript files were generated dynamically but if you just keep doing it over and over it will make it hard to read.

Also you can not access some methods from another jQuery(function(){}); call so that's another reason you don't wanna do that.

With the old window.onload though you will replace the old one every time you specified a function.
