For me, something like Abdelhak Mouaamou's answer works, tested on API level 16 and 27.

Instead of using popupWindow.getContentView().getParent() and casting the result to View (which crashes on API level 16 cause there it returns a ViewRootImpl object which isn't an instance of View) I just use .getRootView() which returns a view already, so no casting required there.

Hope it helps someone :)

complete working example scrambled together from other stackoverflow posts, just copy-paste it, e.g., in the onClick listener of a button:

// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
if(inflater == null) {
    return;
}
//View popupView = inflater.inflate(R.layout.my_popup_layout, null); // this version gives a warning cause it doesn't like null as argument for the viewRoot, c.f. https://stackoverflow.com/questions/24832497 and https://stackoverflow.com/questions/26404951
View popupView = View.inflate(MyParentActivity.this, R.layout.my_popup_layout, null);

// create the popup window
final PopupWindow popupWindow = new PopupWindow(popupView,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        true // lets taps outside the popup also dismiss it
        );

// do something with the stuff in your popup layout, e.g.:
//((TextView)popupView.findViewById(R.id.textview_popup_helloworld))
//      .setText("hello stackoverflow");

// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            popupWindow.dismiss();
            return true;
        }
});

// show the popup window
// which view you pass in doesn't matter, it is only used for the window token
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
//popupWindow.setOutsideTouchable(false); // doesn't seem to change anything for me

View container = popupWindow.getContentView().getRootView();
if(container != null) {
    WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
    WindowManager.LayoutParams p = (WindowManager.LayoutParams)container.getLayoutParams();
    p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
    p.dimAmount = 0.3f;
    if(wm != null) {
        wm.updateViewLayout(container, p);
    }
}

When the toastr message poped up on the screen of firefox. the below tag was displayed in fire bug.

<div class="toast-message">Invalid Credentials, Please check Password</div>.

I took the screenshot at that time. And did the below changes in selenium java code.

String alertText = "";
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("toast-message")));
WebElement toast1 = driver.findElement(By.className("toast-message"));  
alertText = toast1.getText();
System.out.println( alertText);

And my issue of toastr popup got resolved.

are you done with the layout inflating? maybe you can try this!!

View myPoppyView = pw.getContentView();
Button myBelovedButton = (Button)myPoppyView.findViewById(R.id.my_beloved_button);
//do something with my beloved button? :p

if (isset($_POST['Register']))
    {
        $ErrorArrays = array (); //Empty array for input errors 

        $Input_Username = $_POST['Username'];
        $Input_Password = $_POST['Password'];
        $Input_Confirm = $_POST['ConfirmPass'];
        $Input_Email = $_POST['Email'];

        if (empty($Input_Username))
        {
            $ErrorArrays[] = "Username Is Empty";
        }
        if (empty($Input_Password))
        {
            $ErrorArrays[] = "Password Is Empty";
        }
        if ($Input_Password !== $Input_Confirm)
        {
            $ErrorArrays[] = "Passwords Do Not Match!";
        }
        if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

        if (count($ErrorArrays) == 0)
        {
            // No Errors
        }
        else
        {
            foreach ($ErrorArrays AS $Errors)
            {
                echo "<font color='red'><b>".$Errors."</font></b><br>";
            }
        }
    }

?>

    <form method="POST"> 
        Username: <input type='text' name='Username'> <br>
        Password: <input type='password' name='Password'><br>
        Confirm Password: <input type='password' name='ConfirmPass'><br>
        Email: <input type='text' name='Email'> <br><br>

        <input type='submit' name='Register' value='Register'>


    </form> 

This is a very basic PHP Form validation. This could be put in a try block, but for basic reference, I see this fit following our conversation in the comment box.

What this script will do, is process each of the post elements, and act accordingly, for example:

    if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

This will check:

if $Input_Email is not a valid email. If this is not a valid E-mail, then a message will get added to a empty array.

Further down the script, you will see:

    if (count($ErrorArrays) == 0)
    {
        // No Errors
    }
    else
    {
        foreach ($ErrorArrays AS $Errors)
        {
            echo "<font color='red'><b>".$Errors."</font></b><br>";
        }
    }

Basically. if the array count is not 0, errors have been found. Then the script will print out the errors.

Remember, this is a reference based on our conversation in the comment box, and should be used as such.

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

$(document).ready(function() {
$('.popup').click(function(event) {
    window.open($(this).attr("href"), "popupWindow", "width=600,height=600,scrollbars=yes");
 });
});

I recommend you to create a new UIWindow:

UIWindow *window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
window.rootViewController = viewController;
window.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
window.opaque = NO;
window.windowLevel = UIWindowLevelCFShareCircle;
window.backgroundColor = [UIColor clearColor];

[window makeKeyAndVisible];

Then you can manage your view in an other UIViewController. To remove the windows:

[window removeFromSuperview];
window = nil;

hope that will help!

try adding to tsconfig.json file: "noImplicitAny": false worked for me

Open file /etc/environment with a text editor Add the line JAVA_HOME="[path to your java]" Save and close then run source /etc/environment

all is one option:

> A <- c("A", "B", "C", "D")
> B <- A
> C <- c("A", "C", "C", "E")

> all(A==B)
[1] TRUE
> all(A==C)
[1] FALSE

But you may have to watch out for recycling:

> D <- c("A","B","A","B")
> E <- c("A","B")
> all(D==E)
[1] TRUE
> all(length(D)==length(E)) && all(D==E)
[1] FALSE

The documentation for length says it currently only outputs an integer of length 1, but that it may change in the future, so that's why I wrapped the length test in all.

The solution compliant with the v4 of the framework is to set the proper breakpoint. Rather than using .table-responsive, you should be able to use .table-responsive-sm (to be just responsive on small devices)

You can use any of the available endpoints: table-responsive{-sm|-md|-lg|-xl}

I had a similar issue on a custom CoffeeScript file. I solved it by changing the endline encoding from "Unix/Linux" to "Mac OS Classic"

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

Something like this?

var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
alert(res);

convert to date again:

date = new Date(res);
alert(date)

or alternatively:

date = new Date(res);

// hours part from the timestamp
var hours = date.getHours();

// minutes part from the timestamp
var minutes = date.getMinutes();

// seconds part from the timestamp
var seconds = date.getSeconds();

// will display time in 10:30:23 format
var formattedTime = date + '-' + hours + ':' + minutes + ':' + seconds;
alert(formattedTime)

The most simple solution is to use LINQ and then transform the result to a DataTable

    //data is a DataTable that you want to change
    DataTable result = data.AsEnumerable().Distinct().CopyToDataTable < DataRow > ();

This is valid only for asp.net 4.0 ^ Framework and it needs the reference to System.Data.DataSetExtensions as Ivan Ferrer Villa pointed out

I like Ibu's one but, I think I have a better solution using his idea.

//Fade In.
element.style.opacity = 0;
var Op1 = 0;
var Op2 = 1;
var foo1, foo2;
foo1 = setInterval(Timer1, 20);
function Timer1()
{
    element.style.opacity = Op1;
    Op1 = Op1 + .01;
    console.log(Op1); //Option, but I recommend it for testing purposes.
    if (Op1 > 1)
    {
        clearInterval(foo1);
        foo2 = setInterval(Timer3, 20);
    }
}

This solution uses a additional equation unlike Ibu's solution, which used a multiplicative equation. The way it works is it takes a time increment (t), an opacity increment (o), and a opacity limit (l) in the equation, which is: (T = time of fade in miliseconds) [T = (l/o)*t]. the "20" represents the time increments or intervals (t), the ".01" represents the opacity increments (o), and the 1 represents the opacity limit (l). When you plug the numbers in the equation you get 2000 milliseconds (or 2 seconds). Here is the console log:

Notice how the opacity follows the opacity increment amount of .01 just like in the code. If you use the code Ibu made,

//I made slight edits but keeped the ESSENTIAL stuff in it.
var op = 0.01;  // initial opacity
var timer = setInterval(function () {
    if (op >= 1){
        clearInterval(timer);
    }
    element.style.opacity = op;
    op += op * 0.1;
}, 20);

you will get these numbers (or something similar) in you console log. Here is what I got.

Notice that there is no discernible pattern. If you ran Ibu's code, you would never know how long the fade was. You would have to grab a timer and guess and check 2 seconds. Nonetheless, Ibu's code did make a pretty nice fade in (it probably works for fade out. I don't know because I didn't use a fade out yet). My code will also work for a fade out. Let's just say you wanted 2 seconds for a fade out. You can do that with my code. Here is how it would look:

//Fade out. (Continued from the fade in.
function Timer2()
{
    element.style.opacity = Op2;
    Op2 = Op2 - .01;
    console.log(Op2); //Option, but I recommend it for testing purposes.
    if (Op2 < 0)
    { 
        clearInterval(foo2);
    }
}

All I did was change the opacity to 1 (or fully opaque). I changed the opacity increment to -.01 so it would start turning invisible. Lastly, I changed the opacity limit to 0. When it hits the opacity limit, the timer will stop. Same as the last one, except it used 1 instead of 0. When you run the code, here is what the console log should relatively look like.

In the following post, I documented queries to retrieve TABLE and COLUMN comments from Redshift. https://sqlsylvia.wordpress.com/2017/04/29/redshift-comment-views-documenting-data/

Enjoy!

Table Comments

    SELECT n.nspname AS schema_name
     , pg_get_userbyid(c.relowner) AS table_owner
     , c.relname AS table_name
     , CASE WHEN c.relkind = 'v' THEN 'view' ELSE 'table' END 
       AS table_type
     , d.description AS table_description
     FROM pg_class As c
     LEFT JOIN pg_namespace n ON n.oid = c.relnamespace
     LEFT JOIN pg_tablespace t ON t.oid = c.reltablespace
     LEFT JOIN pg_description As d 
          ON (d.objoid = c.oid AND d.objsubid = 0)
     WHERE c.relkind IN('r', 'v') AND d.description > ''
     ORDER BY n.nspname, c.relname ;

Column Comments

    SELECT n.nspname AS schema_name
     , pg_get_userbyid(c.relowner) AS table_owner
     , c.relname AS table_name
     , a.attname AS column_name
     , d.description AS column_description
    FROM pg_class AS c
    INNER JOIN pg_attribute As a ON c.oid = a.attrelid
    INNER JOIN pg_namespace n ON n.oid = c.relnamespace
    LEFT JOIN pg_tablespace t ON t.oid = c.reltablespace
    LEFT JOIN pg_description As d 
     ON (d.objoid = c.oid AND d.objsubid = a.attnum)
    WHERE c.relkind IN('r', 'v')
     AND a.attname NOT         
     IN ('cmax', 'oid', 'cmin', 'deletexid', 'ctid', 'tableoid','xmax', 'xmin', 'insertxid')
    ORDER BY n.nspname, c.relname, a.attname;

To answer the question about mappings: your provided __iter__ should iterate over the keys of the mapping. The following is a simple example that creates a mapping x -> x * x and works on Python3 extending the ABC mapping.

import collections.abc

class MyMap(collections.abc.Mapping):
    def __init__(self, n):
        self.n = n

    def __getitem__(self, key): # given a key, return it's value
        if 0 <= key < self.n:
            return key * key
        else:
            raise KeyError('Invalid key')

    def __iter__(self): # iterate over all keys
        for x in range(self.n):
            yield x

    def __len__(self):
        return self.n

m = MyMap(5)
for k, v in m.items():
    print(k, '->', v)
# 0 -> 0
# 1 -> 1
# 2 -> 4
# 3 -> 9
# 4 -> 16

As I understand it, this is the default way of using the web driver.

from s in context.shift
where !context.employeeshift.Any(es=>(es.shiftid==s.shiftid)&&(es.empid==57))
select s;

Hope this helps

Well, you essentially create a JDialog, add your text components and make it visible. It might help if you narrow down which specific bit you're having trouble with.

If the above CMD command option is not working and you cannot make it work in any other way then follow this below.

Click on below link

http://adbshell.com/downloads

and download the first link with name ADB Kits ( contains adb.exe and necessary .dll files).

After downloading replace these files with the ones in the path

Android/Sdk/platform-tools/

Now click on adb.exe and it will open cmd and will start the adb server.

Now it will detect the device and no problem. OOOOOllllaaaaa.....

If the Problem persists again then do the same... save the folder somewhere.... just replace files... it will detect the device automatically then

forfiles is very useful, for instance, to recursive delete all files older than two days

forfiles /D -2 /P "C:\Temp" /S /C "cmd /c del @path"

For people coming from the future, you can now do this purely in CSS.

.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black; 
  margin: 5rem;
}

/* Tooltip text */
.tooltip .tooltiptext {
  visibility: hidden;
  background-color: black;
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;

  width: 120px;
  bottom: 100%;
  left: 50%;
  margin-left: -60px;

  position: absolute;
  z-index: 1;
}

/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext {
  visibility: visible;
}

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

Beans.xml or file.XML is not placed under proper path. You should add the XML file under the resource folder, if you have a Maven project. src -> main -> java -> resources

I have an amazing solution to achieve this make a BaseActivity like this.

public class BaseActivity extends AppCompatActivity {

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this));


}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
    switch (requestCode) {
        case 1: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                CustomToast.getInstance().setCustomToast("Now you can share the Hack.");

            } else {
                Toast.makeText(this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
            }
        }
    }
}

}

Now yo can call the code to ask for permission like this

 ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

Now every time this happens anywhere whether in your fragment or in any activity the base activity would be called.

Thanks

sys.exit() will do exactly what you want.

import sys
sys.exit("Error message")

Check below code may will help you, Using stroke can make border in edit text and change it's color too as shown below...

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<stroke
    android:width="2dp"
    android:color="@color/secondary" />
<corners
    android:bottomLeftRadius="10dp"
    android:bottomRightRadius="10dp"
    android:topLeftRadius="10dp"
    android:topRightRadius="10dp" />

Add this as background in to edit text. Thanks!

You say you want to delete any column with the title "Percent Margin of Error" so let's try to make this dynamic instead of naming columns directly.

Sub deleteCol()

On Error Resume Next

Dim wbCurrent As Workbook
Dim wsCurrent As Worksheet
Dim nLastCol, i As Integer

Set wbCurrent = ActiveWorkbook
Set wsCurrent = wbCurrent.ActiveSheet
'This next variable will get the column number of the very last column that has data in it, so we can use it in a loop later
nLastCol = wsCurrent.Cells.Find("*", LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

'This loop will go through each column header and delete the column if the header contains "Percent Margin of Error"
For i = nLastCol To 1 Step -1
    If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) > 0 Then
        wsCurrent.Columns(i).Delete Shift:=xlShiftToLeft
    End If
Next i

End Sub

With this you won't need to worry about where you data is pasted/imported to, as long as the column headers are in the first row.

EDIT: And if your headers aren't in the first row, it would be a really simple change. In this part of the code: If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) change the "1" in Cells(1, i) to whatever row your headers are in.

EDIT 2: Changed the For section of the code to account for completely empty columns.

I am using jQuery and the code below working for me,

var iframe = $(window.top.document).find("#iframe_id_here");
iframe.height(iframe.contents().height()+'px' );

For the MVC Controller method, use a nullable boolean type:

public ActionResult Index( string responsables, bool? checkResp) { etc. }

Then if the check box is checked, checkResp will be true. If not, it will be null.

Try to set ENV PATH. Add PHP path in to ENV PATH.

In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll

http://php.net/manual/en/openssl.installation.php

See here:

http://jaanus.com/blog/2012/02/12/debugging-http-on-an-android-phone-or-tablet-with-charles-proxy-for-fun-and-profit/

You would need to install the charles.crt certificate to your device.

Consider using the decorator pattern http://en.wikipedia.org/wiki/Decorator_pattern

You can change the decorator at runtime with one that has different properties when an event occurs.

update TABLENAME
set COLUMNNAME = COLUMNNAME + 1

I think the answers above are missing a simple approach that I've found very useful.

When I have a file that is too large to load in memory, I break up the file into multiple smaller files (either by row or cols)

Example: In case of 30 days worth of trading data of ~30GB size, I break it into a file per day of ~1GB size. I subsequently process each file separately and aggregate results at the end

One of the biggest advantages is that it allows parallel processing of the files (either multiple threads or processes)

The other advantage is that file manipulation (like adding/removing dates in the example) can be accomplished by regular shell commands, which is not be possible in more advanced/complicated file formats

This approach doesn't cover all scenarios, but is very useful in a lot of them

Because python checks in the directories in sequential order starting at the first directory in sys.path list, till it find the .py file it was looking for.

Ideally, the current directory or the directory of the script is the first always the first element in the list, unless you modify it, like you did. From documentation -

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

So, most probably, you had a .py file with the same name as the module you were trying to import from, in the current directory (where the script was being run from).

Also, a thing to note about ImportErrors , lets say the import error says - ImportError: No module named main - it doesn't mean the main.py is overwritten, no if that was overwritten we would not be having issues trying to read it. Its some module above this that got overwritten with a .py or some other file.

Example -

My directory structure looks like -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py

Now From testmain.py , I call from shared import phtest , it works fine.

Now lets say I introduce a shared.py in test directory` , example -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py 
  - shared.py

Now when I try to do from shared import phtest from testmain.py , I will get the error -

ImportError: cannot import name 'phtest'

As you can see above, the file that is causing the issue is shared.py , not phtest.py .

UPDATE

I've just given TouchImageView a new update. It now includes Double Tap Zoom and Fling in addition to Panning and Pinch Zoom. The code below is very dated. You can check out the github project to get the latest code.

USAGE

Place TouchImageView.java in your project. It can then be used the same as ImageView. Example:

TouchImageView img = (TouchImageView) findViewById(R.id.img);

If you are using TouchImageView in xml, then you must provide the full package name, because it is a custom view. Example:

<com.example.touch.TouchImageView
    android:id="@+id/img”
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Note: I've removed my prior answer, which included some very old code and now link straight to the most updated code on github.

ViewPager

If you are interested in putting TouchImageView in a ViewPager, refer to this answer.

var posNum = (num < 0) ? num * -1 : num; // if num is negative multiple by negative one ... 

I find this solution easy to understand.

In MonoDroid here's how (c#)

/// <summary>
/// Graphics support for resizing images
/// </summary>
public static class Graphics
{
    public static Bitmap ScaleDownBitmap(Bitmap originalImage, float maxImageSize, bool filter)
    {
        float ratio = Math.Min((float)maxImageSize / originalImage.Width, (float)maxImageSize / originalImage.Height);
        int width = (int)Math.Round(ratio * (float)originalImage.Width);
        int height =(int) Math.Round(ratio * (float)originalImage.Height);

        Bitmap newBitmap = Bitmap.CreateScaledBitmap(originalImage, width, height, filter);
        return newBitmap;
    }

    public static Bitmap ScaleBitmap(Bitmap originalImage, int wantedWidth, int wantedHeight)
    {
        Bitmap output = Bitmap.CreateBitmap(wantedWidth, wantedHeight, Bitmap.Config.Argb8888);
        Canvas canvas = new Canvas(output);
        Matrix m = new Matrix();
        m.SetScale((float)wantedWidth / originalImage.Width, (float)wantedHeight / originalImage.Height);
        canvas.DrawBitmap(originalImage, m, new Paint());
        return output;
    }

}

This generally (almost always) performs better than a cursor and is simpler:

DECLARE @PractitionerList TABLE(PracticionerID INT)
DECLARE @PracticionerID INT
    
INSERT @PractitionerList(PracticionerID)
SELECT PracticionerID
FROM Practitioner
    
WHILE(1 = 1)
BEGIN
            
    SET @PracticionerID = NULL
    SELECT TOP(1) @PracticionerID = PracticionerID
    FROM @PractitionerList
    
    IF @PracticionerID IS NULL
        BREAK
            
    PRINT 'DO STUFF'
    
    DELETE TOP(1) FROM @PractitionerList
    
END

This is a refresh button method, but it works well in my application. in finish() you kill the instances

public void refresh(View view){          //refresh is onClick name given to the button
    onRestart();
}

@Override
protected void onRestart() {

    // TODO Auto-generated method stub
    super.onRestart();
    Intent i = new Intent(lala.this, lala.class);  //your class
    startActivity(i);
    finish();

}

The gist

In Node.js, __dirname is always the directory in which the currently executing script resides (see this). So if you typed __dirname into /d1/d2/myscript.js, the value would be /d1/d2.

By contrast, . gives you the directory from which you ran the node command in your terminal window (i.e. your working directory) when you use libraries like path and fs. Technically, it starts out as your working directory but can be changed using process.chdir().

The exception is when you use . with require(). The path inside require is always relative to the file containing the call to require.

For example...

Let's say your directory structure is

/dir1
  /dir2
    pathtest.js

and pathtest.js contains

var path = require("path");
console.log(". = %s", path.resolve("."));
console.log("__dirname = %s", path.resolve(__dirname));

and you do

cd /dir1/dir2
node pathtest.js

you get

. = /dir1/dir2
__dirname = /dir1/dir2

Your working directory is /dir1/dir2 so that's what . resolves to. Since pathtest.js is located in /dir1/dir2 that's what __dirname resolves to as well.

However, if you run the script from /dir1

cd /dir1
node dir2/pathtest.js

you get

. = /dir1
__dirname = /dir1/dir2

In that case, your working directory was /dir1 so that's what . resolved to, but __dirname still resolves to /dir1/dir2.

Using . inside require...

If inside dir2/pathtest.js you have a require call into include a file inside dir1 you would always do

require('../thefile')

because the path inside require is always relative to the file in which you are calling it. It has nothing to do with your working directory.

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

You need to use ScriptManager.RegisterStartupScript for Ajax.

Example with updating existent parameters.

Also url_encode used, and possibility to don't specify parameter value

        if ($query) {
            parse_str($query, $queryParams);
            $queryParams[$key] = $value;
            $url = str_replace("?$query", '?' . http_build_query($queryParams), $url);
        } else {
            $url .= '?' . urlencode($key) . '=' . urlencode($value);
        }
        return $url;
    }

Installing libffi-dev and re-installing python3.7 fixed the problem for me.

to cleanly build py 3.7 libffi-dev is required or else later stuff will fail

If using RHEL/Fedora:

yum install libffi-devel

or

sudo dnf install libffi-devel

If using Debian/Ubuntu:

sudo apt-get install libffi-dev

[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*

This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.

If the variables are being generated and not saved to a file you cannot pipe them in into source. The deceptively simple way to do it is this:

some command | xargs

You just need to delete the branch you are on. You can't use git branch -D as this has a safety check against doing this. You can use update-ref to do this.

git update-ref -d HEAD

Do not use rm -rf .git or anything like this as this will completely wipe your entire repository including all other branches as well as the branch that you are trying to reset.

.md is markdown. README.md is used to generate the html summary you see at the bottom of projects. Github has their own flavor of Markdown.

Order of Preference: If you have two files named README and README.md, the file named README.md is preferred, and it will be used to generate github's html summary.

FWIW, Stack Overflow uses local Markdown modifications as well (also see Stack Overflow's C# Markdown Processor)

It's a language abstraction - some languages have both, some one, some neither.

In the case of C++, the code is not run in either the stack or the heap. You can test what happens if you run out of heap memory by repeatingly calling new to allocate memory in a loop without calling delete to free it it. But make a system backup before doing this.

You have to enable curl with php.

You can use the title element as Phrogz indicated. There are also some good tooltips like jQuery's Tipsy http://onehackoranother.com/projects/jquery/tipsy/ (which can be used to replace all title elements), Bob Monteverde's nvd3 or even the Twitter's tooltip from their Bootstrap http://twitter.github.com/bootstrap/

you can do it using the format function, here is a sample:

Format(mydate, "yyyy-MM-dd HH:mm:ss")

Complete instructions on how to do this using the "jQuery-ajaxTransport-XDomainRequest" plugin can be found here: https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest#instructions

This plugin is actively supported, and handles HTML, JSON and XML. The file is also hosted on CDNJS, so you can directly drop the script into your page with no additional setup: http://cdnjs.cloudflare.com/ajax/libs/jquery-ajaxtransport-xdomainrequest/1.0.1/jquery.xdomainrequest.min.js

To give a bit more specific answer. HTML5 allows you to get the geo coordinates, and it does a pretty decent job. Overall the browser support for geolocation is pretty good, all major browsers except ie7 and ie8 (and opera mini). IE9 does the job but is the worst performer. Checkout caniuse.com:

http://caniuse.com/#search=geol

Also you need the approval of your user to access their location, so make sure you check for this and give some decent instructions in case it's turned off. Especially for Iphone turning permissions on for Safari is a bit cumbersome.

A command-line process such cmd.exe or mysql.exe will usually read (and execute) whatever you (the user) type in (at the keyboard).

To mimic that, I think you want to use the RedirectStandardInput property: http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandardinput.aspx

There are some well-known programming techniques that will help you to minimize the risk of getting memory leaks at first hand:

• if you have to do your own dynamic memory allocation, write new and delete always pairwise, and make sure the allocation/deallocation code is called pairwise
• avoid dynamic memory allocation if you can. For example, use vector<T> t whereever possible instead of T* t = new T[size]
• use "smart pointers" like boost smart pointers (http://www.boost.org/doc/libs/1_46_1/libs/smart_ptr/smart_ptr.htm)
• my personal favorite: make sure you have understood the concept of ownership of a pointer, and make sure that everywhere where you use pointers, you know which code entity is the owner
• learn which constructors / assignment operators are automatically created by the C++ compiler, and what that means if you have class that owns a pointer (or what that means if you have a class that contains a pointer to an object it does not own).

This is a common issue if the Zookeeper server is not running or no longer running (i.e. it crashed after you started it).

So first, check that you have the Zookeeper server running. A simple way to check is grep the running processes:

# ps -ef | grep zookeeper

(run this a couple of times to see if the same process ID is still there. its possible it keep restarting with a new process ID. Alternatively you can use 'systemctl status zookeeper' if your Linux distro support systemd)

You should see the process running as a java process:

# ps -ef | grep zookeeper
root       492     0  0 00:01 pts/1    00:00:00 java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /root/zookeeper-3.5.0-alpha/bin/../build/classes:/root/zookeeper-3.5.0-alpha/bin/../build/lib/*.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/slf4j-log4j12-1.7.5.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/slf4j-api-1.7.5.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/servlet-api-2.5-20081211.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/netty-3.7.0.Final.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/log4j-1.2.16.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jline-2.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jetty-util-6.1.26.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jetty-6.1.26.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/javacc.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jackson-mapper-asl-1.9.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jackson-core-asl-1.9.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/commons-cli-1.2.jar:/root/zookeeper-3.5.0-alpha/bin/../zookeeper-3.5.0-alpha.jar:/root/zookeeper-3.5.0-alpha/bin/../src/java/lib/*.jar:/root/zookeeper-3.5.0-alpha/bin/../conf: -Xmx1000m -Xmx1000m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /root/zookeeper-3.5.0-alpha/bin/../conf/zoo.cfg

If its not there, then there's likely something in the zookeeper log file indicating the issue.

To find the zookeeper log file, you should first figure out where its configured for logging. In my case I have zookeeper installed under my root directory (not suggesting you install it there):

[root@centos6_zookeeper conf]# pwd
/root/zookeeper-3.5.0-alpha/conf

And you can find the log setting in this file:

[root@centos6_zookeeper conf]# grep "zookeeper.log" log4j.properties 
zookeeper.log.dir=/var/log
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=INFO
zookeeper.log.maxfilesize=256MB
zookeeper.log.maxbackupindex=20

So Zookeeper is configured to log under /var/log.

Then there's usually a zookeeper.log and/or zookeeper.out file which should indicate your startup error.

The globals() function returns a dictionary, where keys are names of objects you can name (and values, by the way, are ids of these objects) The exec() function takes a string and executes it as if you just type it in a python console. So, the code is

for i in list(globals().keys()):
    if(i[0] != '_'):
        exec('del {}'.format(i))

I think the simplest way is that:

type InputEvent = React.ChangeEvent<HTMLInputElement>;
type ButtonEvent = React.MouseEvent<HTMLButtonElement>;

update = (e: InputEvent): void => this.props.login[e.target.name] = e.target.value;
submit = (e:  ButtonEvent): void => {
    this.props.login.logIn();
    e.preventDefault();
}

Are you possibly depending on development versions that obviously change a lot during development?

Instead of incrementing the version of development releases, you could just use a snapshot version that you overwrite when necessary, which means you wouldn't have to change the version tag on every minor change. Something like 1.0-SNAPSHOT...

But maybe you are trying to achieve something else ;)

Had the same issue. Sorted it by defer loading select2

<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.8/js/select2.min.js" defer></script>

It means you're trying to install an app with the same packageName as an app that's already installed on the emulator, but the one you're trying to install has a lower versionCode (integer value for your version number).

You might have installed from a separate copy of the code where the version number was higher than the copy you're working with right now. In either case, either:

• uninstall the currently installed copy

• or open up your phone's Settings > Application Manager to determine the version number for the installed app, and increment your <manifest android:versionCode to be higher in the AndroidManifest.

• or https://stackoverflow.com/a/13772620/632951

df[sapply(df, function(x) all(is.na(x)))] <- NULL

I think this would be easiest one:

test1.ForEach(str => test2.RemoveAll(x=>x.Contains(str)));

JavaScript is what you need. If you are loading iframe when loading the page, insert the test for iframe using the onload event. If iframe is inserted in realtime, then create a callback function on insertion and hook in whatever action you need to take :)

You have two records in your json file, and json.loads() is not able to decode more than one. You need to do it record by record.

See Python json.loads shows ValueError: Extra data

OR you need to reformat your json to contain an array:

{
    "foo" : [
       {"name": "XYZ", "address": "54.7168,94.0215", "country_of_residence": "PQR", "countries": "LMN;PQRST", "date": "28-AUG-2008", "type": null},
       {"name": "OLMS", "address": null, "country_of_residence": null, "countries": "Not identified;No", "date": "23-FEB-2017", "type": null}
    ]
}

would be acceptable again. But there cannot be several top level objects.

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:

SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)

and then run it with

EXECUTE (@SQL_SCRIPT)

It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!

You can't EXEC multiple batches. GO is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC each one after substitution.

I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO; I've done that in ADO.NET code.

And where did I get the word "SERVERNAME" from?

Here's some code that I just tested (and which works):

DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'

DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)

SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'

DECLARE @SQL_SCRIPT VARCHAR(MAX)

SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

The -nc, --no-clobber option isn't the best solution as newer files will not be downloaded. One should use -N instead which will download and overwrite the file only if the server has a newer version, so the correct answer is:

wget -N http://www.example.com/images/misc/pic.png

Then running Wget with -N, with or without -r or -p, the decision as to whether or not to download a newer copy of a file depends on the local and remote timestamp and size of the file. -nc may not be specified at the same time as -N.

-N, --timestamping: Turn on time-stamping.

Angular-ui comes with dialog directive.Use it and set templateurl to whatever page you want to include.That is the most elegant way and i have used it in my project as well. You can pass several other parameters for dialog as per need.

Your pip is a soft link to the same executable file path with pip3. you can use the commands below to check where your pip and pip3 real paths are:

$ ls -l `which pip`
$ ls -l `which pip3`

You may also use the commands below to know more details:

$ pip show pip
$ pip3 show pip

When we install different versions of python, we may create such soft links to

• set default pip to some version.
• make different links for different versions.

It is the same situation with python, python2, python3

You don't need to create the SSH keys on the Jenkins server, nor do you need to store the SSH keys on the Jenkins server's filesystem. This bit of information is crucial in environments where Jenkins servers instances may be created and destroyed frequently.

Generating the SSH Key Pair

On any machine (Windows, Linux, MacOS ...doesn't matter) generate an SSH key pair. Use this article as guide:

• GitHub: Generating a new SSH key and adding it to the ssh-agent (you can skip the section "Adding your SSH key to the ssh-agent")

On the Target Server

On the target server, you will need to place the content of the public key (id_rsa.pub per the above article) into the .ssh/authorized_keys file under the home directory of the user which Jenkins will be using for deployment.

In Jenkins

Using "Publish over SSH" Plugin

Ref: https://plugins.jenkins.io/publish-over-ssh/

Visit: Jenkins > Manage Jenkins > Configure System > Publish over SSH

• If the private key is encrypted, then you will need to enter the passphrase for the key into the "Passphrase" field, otherwise leave it alone.
• Leave the "Path to key" field empty as this will be ignored anyway when you use a pasted key (next step)
• Copy and paste the contents of the private key (id_rsa per the above article) into the "Key" field
• Under "SSH Servers", "Add" a new server configuration for your target server.

Using Stored Global Credentials

Visit: Jenkins > Credentials > System > Global credentials (unrestricted) > Add Credentials

• Kind: "SSH Username with private key"
• Scope: "Global"
• ID: [CREAT A UNIQUE ID FOR THIS KEY]
• Description: [optionally, enter a decription]
• Username: [USERNAME JENKINS WILL USE TO CONNECT TO REMOTE SERVER]
• Private Key: [select "Enter directly"]
• Key: [paste the contents of the private key (id_rsa per the above article)]
• Passphrase: [enter the passphrase for the key, or leave it blank if the key is not encrypted]

I found the issue. This is a firewall message and an error was occurring in the VB script due to wrong data in database, but the error was not logged/caught properly.

I had the same issue and was not satisfied with any of the answers so far since none of them guaranteed unique IDs.

I too wanted to print object IDs for debugging purposed. I knew there must be some way to do it, because in the Eclipse debugger, it specifies unique IDs for each object.

I came up with a solution based on the fact that the "==" operator for objects only returns true if the two objects are actually the same instance.

import java.util.HashMap;
import java.util.Map;

/**
 *  Utility for assigning a unique ID to objects and fetching objects given
 *  a specified ID
 */
public class ObjectIDBank {

    /**Singleton instance*/
    private static ObjectIDBank instance;

    /**Counting value to ensure unique incrementing IDs*/
    private long nextId = 1;

    /** Map from ObjectEntry to the objects corresponding ID*/
    private Map<ObjectEntry, Long> ids = new HashMap<ObjectEntry, Long>();

    /** Map from assigned IDs to their corresponding objects */
    private Map<Long, Object> objects = new HashMap<Long, Object>();

    /**Private constructor to ensure it is only instantiated by the singleton pattern*/
    private ObjectIDBank(){}

    /**Fetches the singleton instance of ObjectIDBank */
    public static ObjectIDBank instance() {
        if(instance == null)
            instance = new ObjectIDBank();

        return instance;
    }

    /** Fetches a unique ID for the specified object. If this method is called multiple
     * times with the same object, it is guaranteed to return the same value. It is also guaranteed
     * to never return the same value for different object instances (until we run out of IDs that can
     * be represented by a long of course)
     * @param obj The object instance for which we want to fetch an ID
     * @return Non zero unique ID or 0 if obj == null
     */
    public long getId(Object obj) {

        if(obj == null)
            return 0;

        ObjectEntry objEntry = new ObjectEntry(obj);

        if(!ids.containsKey(objEntry)) {
            ids.put(objEntry, nextId);
            objects.put(nextId++, obj);
        }

        return ids.get(objEntry);
    }

    /**
     * Fetches the object that has been assigned the specified ID, or null if no object is
     * assigned the given id
     * @param id Id of the object
     * @return The corresponding object or null
     */
    public Object getObject(long id) {
        return objects.get(id);
    }


    /**
     * Wrapper around an Object used as the key for the ids map. The wrapper is needed to
     * ensure that the equals method only returns true if the two objects are the same instance
     * and to ensure that the hash code is always the same for the same instance.
     */
    private class ObjectEntry {
        private Object obj;

        /** Instantiates an ObjectEntry wrapper around the specified object*/
        public ObjectEntry(Object obj) {
            this.obj = obj;
        }


        /** Returns true if and only if the objects contained in this wrapper and the other
         * wrapper are the exact same object (same instance, not just equivalent)*/
        @Override
        public boolean equals(Object other) {
            return obj == ((ObjectEntry)other).obj;
        }


        /**
         * Returns the contained object's identityHashCode. Note that identityHashCode values
         * are not guaranteed to be unique from object to object, but the hash code is guaranteed to
         * not change over time for a given instance of an Object.
         */
        @Override
        public int hashCode() {
            return System.identityHashCode(obj);
        }
    }
}

I believe that this should ensure unique IDs throughout the lifetime of the program. Note, however, that you probably don't want to use this in a production application because it maintains references to all of the objects for which you generate IDs. This means that any objects for which you create an ID will never be garbage collected.

Since I'm using this for debug purposes, I'm not too concerned with the memory being freed.

You could modify this to allow clearing Objects or removing individual objects if freeing memory is a concern.

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

>>> a=[]
>>> a.append([1,2])
>>> a
[[1, 2]]
>>> a=[]
>>> a+=[1,2]
>>> a
[1, 2]

See that append adds a single element to the list, which may be anything. +=[] joins the lists.

With java 8, we can do like below to check if one list contains any element of other list

boolean var = lis1.stream().filter(element -> list2.contains(element)).findFirst().isPresent();

$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

Personally I don't find the standard diagramming technique very helpful - the arrows always seem to point the wrong way for me. (They generally point towards the "parent" of each commit, which ends up being backwards in time, which is weird).

To explain it in words:

• When you rebase your branch onto their branch, you tell Git to make it look as though you checked out their branch cleanly, then did all your work starting from there. That makes a clean, conceptually simple package of changes that someone can review. You can repeat this process again when there are new changes on their branch, and you will always end up with a clean set of changes "on the tip" of their branch.
• When you merge their branch into your branch, you tie the two branch histories together at this point. If you do this again later with more changes, you begin to create an interleaved thread of histories: some of their changes, some of my changes, some of their changes. Some people find this messy or undesirable.

For reasons I don't understand, GUI tools for Git have never made much of an effort to present merge histories more cleanly, abstracting out the individual merges. So if you want a "clean history", you need to use rebase.

I seem to recall having read blog posts from programmers who only use rebase and others that never use rebase.

Example

I'll try explaining this with a just-words example. Let's say other people on your project are working on the user interface, and you're writing documentation. Without rebase, your history might look something like:

Write tutorial
Merge remote-tracking branch 'origin/master' into fixdocs
Bigger buttons
Drop down list
Extend README
Merge remote-tracking branch 'origin/master' into fixdocs
Make window larger
Fix a mistake in howto.md

That is, merges and UI commits in the middle of your documentation commits.

If you rebased your code onto master instead of merging it, it would look like this:

Write tutorial
Extend README
Fix a mistake in howto.md
Bigger buttons
Drop down list
Make window larger

All of your commits are at the top (newest), followed by the rest of the master branch.

(Disclaimer: I'm the author of the "10 things I hate about Git" post referred to in another answer)

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

>>> def func(a, *args, **kwargs):
...   print 'a %s, args %s, kwargs %s' % (a, args, kwargs)
... 
>>> func('one', 'two', 'three', four='four', five='five')
a one, args ('two', 'three'), kwargs {'four': 'four', 'five': 'five'}

>>> def anotherfunct(beta, *args):
...   print 'beta %s, args %s' % (beta, args)
... 
>>> def func(a, *args, **kwargs):
...   anotherfunct(a, *args)
... 
>>> func('one', 'two', 'three', four='four', five='five')
beta one, args ('two', 'three')
>>> 

You can specify a formatter and use lstart, like this command:

ps -eo pid,lstart,cmd

The above command will output all processes, with formatters to get PID, command run, and date+time started.

Example (from Debian/Jessie command line)

$ ps -eo pid,lstart,cmd
  PID CMD                                          STARTED
    1 Tue Jun  7 01:29:38 2016 /sbin/init                  
    2 Tue Jun  7 01:29:38 2016 [kthreadd]                  
    3 Tue Jun  7 01:29:38 2016 [ksoftirqd/0]               
    5 Tue Jun  7 01:29:38 2016 [kworker/0:0H]              
    7 Tue Jun  7 01:29:38 2016 [rcu_sched]                 
    8 Tue Jun  7 01:29:38 2016 [rcu_bh]                    
    9 Tue Jun  7 01:29:38 2016 [migration/0]               
   10 Tue Jun  7 01:29:38 2016 [kdevtmpfs]                 
   11 Tue Jun  7 01:29:38 2016 [netns]                     
  277 Tue Jun  7 01:29:38 2016 [writeback]                 
  279 Tue Jun  7 01:29:38 2016 [crypto]                    
      ...

You can read ps's manpage or check Opengroup's page for the other formatters.

Use the Nlog http://nlog-project.org/. It is free and allows to write to file, database, event log and other 20+ targets. The other logging framework is log4net - http://logging.apache.org/log4net/ (ported from java Log4j project). Its also free.

Best practices are to use common logging - http://commons.apache.org/logging/ So you can later change NLog or log4net to other logging framework.

If you want to change the bar/line color and the hint text color of the TextInputLayout (what the accent color normally is), then just create this style:

<style name="MyStyle">
    <item name="colorAccent">@color/your_color</item>
</style>

Then apply it to your TextInputLayout as a theme:

<android.support.design.widget.TextInputLayout
    ...
    app:theme="@style/MyStyle" />

This basically sets a theme (not style) to one view (as opposed to the whole activity).

You could use dplyr::filter() and negate a grepl() match:

library(dplyr)

df %>% 
  filter(!grepl('REVERSE', Name))

Or with dplyr::filter() and negating a stringr::str_detect() match:

library(stringr)

df %>% 
  filter(!str_detect(Name, 'REVERSE'))

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

None of these answers achieved what I was looking for, so I wound up writing something myself. I wanted to pinch-zoom an image on my website using my MacBookPro trackpad. The following code (which requires jQuery) seems to work in Chrome and Edge, at least. Maybe this will be of use to someone else.

function setupImageEnlargement(el)
{
    // "el" represents the image element, such as the results of document.getElementByd('image-id')
    var img = $(el);
    $(window, 'html', 'body').bind('scroll touchmove mousewheel', function(e)
    {
        //TODO: need to limit this to when the mouse is over the image in question

        //TODO: behavior not the same in Safari and FF, but seems to work in Edge and Chrome

        if (typeof e.originalEvent != 'undefined' && e.originalEvent != null
            && e.originalEvent.wheelDelta != 'undefined' && e.originalEvent.wheelDelta != null)
        {
            e.preventDefault();
            e.stopPropagation();
            console.log(e);
            if (e.originalEvent.wheelDelta > 0)
            {
                // zooming
                var newW = 1.1 * parseFloat(img.width());
                var newH = 1.1 * parseFloat(img.height());
                if (newW < el.naturalWidth && newH < el.naturalHeight)
                {
                    // Go ahead and zoom the image
                    //console.log('zooming the image');
                    img.css(

                    });
                }
                else
                {
                    // Make image as big as it gets
                    //console.log('making it as big as it gets');
                    img.css(
                    {
                        "width": el.naturalWidth + 'px',
                        "height": el.naturalHeight + 'px',
                        "max-width": el.naturalWidth + 'px',
                        "max-height": el.naturalHeight + 'px'

                // If your image is normally 100% width, you may need to change these values on resize.
                var origW = parseFloat(img.attr('data-startwidth'));
                var origH = parseFloat(img.attr('data-startheight'));

                    // This restores the image to its original size. You may want
                    //to do this differently, like by removing the css instead of defining it.
                    img.css(
                    {
                        "width": origW + 'px',

            }
        }
    });
}

Andreas, I've also been looking for an "email-to-id" ellegant solution and couldn't find one. However, as you said, screen scraping is not such a bad idea in this case, because emails are unique and you either get a single match or none. As long as Facebook don't change their search page drastically, the following will do the trick:

final static String USER_SEARCH_QUERY = "http://www.facebook.com/search.php?init=s:email&q=%s&type=users";
final static String USER_URL_PREFIX = "http://www.facebook.com/profile.php?id=";

public static String emailToID(String email)
{
    try
    {
        String html = getHTML(String.format(USER_SEARCH_QUERY, email));
        if (html != null)
        {
            int i = html.indexOf(USER_URL_PREFIX) + USER_URL_PREFIX.length();
            if (i > 0)
            {
                StringBuilder sb = new StringBuilder();
                char c;
                while (Character.isDigit(c = html.charAt(i++)))
                    sb.append(c);
                if (sb.length() > 0)
                    return sb.toString();
            }
        }
    } catch (Exception e)
    {
        e.printStackTrace();
    }
    return null;
}

private static String getHTML(String htmlUrl) throws MalformedURLException, IOException
{
    StringBuilder response = new StringBuilder();
    URL url = new URL(htmlUrl);
    HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
    httpConn.setRequestMethod("GET");
    if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK)
    {
        BufferedReader input = new BufferedReader(new InputStreamReader(httpConn.getInputStream()), 8192);
        String strLine = null;
        while ((strLine = input.readLine()) != null)
            response.append(strLine);
        input.close();
    }
    return (response.length() == 0) ? null : response.toString();
}

If you have Login in a seperate folder within your project make sure that where you are using it you do:

using FootballLeagueSystem.[Whatever folder you are using]

The res.header('Access-Control-Allow-Origin', '*'); wouldn't work with Autorization header. Just enable pre-flight request, using cors library:

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.options('*', cors())

You could do this with the CSS3 :target selector.

menu:hover block {
    visibility: visible;
}

block:target {
    visibility:hidden;
}

Once you've got expandtab on as per the other answers, the extremely convenient way to convert existing files according to your new settings is:

:retab

It will work on the current buffer.

In my case I got the error as

node_modules/@types/es6-promise/index.d.ts(11,15): error TS2300: Duplicate identifier 'Promise'.

And I had @types/es6-promise on my package.json but my tsconfig was already with target: "es6". So I guess there was a conflict with Promise when compiling.

Removing @types/es6-promise from my package.json file solved the issue.

Here is a quick and simple solution using PowerShell:

powershell.exe -nologo -noprofile -command "& { $shell = New-Object -COM Shell.Application; $target = $shell.NameSpace('C:\extractToThisDirectory'); $zip = $shell.NameSpace('C:\extractThis.zip'); $target.CopyHere($zip.Items(), 16); }"

This uses the built-in extract functionality of the Explorer and will also show the typical extract progress window. The second parameter 16 to CopyHere answers all questions with yes.

Application.SetOption "Auto compact", False '(mentioned above) Use this with a button caption: "DB Not Compact On Close"

Write code to toggle the caption with "DB Compact On Close" along with Application.SetOption "Auto compact", True

AutoCompact can be set by means of the button or by code, ex: after importing large temp tables.

The start up form can have code that turns off Auto Compact, so that it doesn't run every time.

This way, you are not trying to fight Access.

Maybe try this? It seems the problem is solved after remove all the handlers in my case.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

logging.basicConfig(filename='output.log', level=logging.INFO)

It is possible to download a file using XHR request. You can use angular $http to load the file and then use Blob feature of HTML5 to make browser save it. There is a library that can help you with saving: FileSaver.js.

arr.0
arr.1

etc.

Using Apache Commons IO.

import org.apache.commons.io.FileUtils;

//...

String contents = FileUtils.readFileToString(new File("/path/to/the/file"), "UTF-8")

You can see de javadoc for the method for details.

Here is the utility I wrote to generate a simple setup.py file (template) with useful comments and links. I hope, it will be useful.

Installation

sudo pip install setup-py-cli

Usage

To generate setup.py file just type in the terminal.

setup-py

Now setup.py file should occur in the current directory.

Generated setup.py

from distutils.core import setup
from setuptools import find_packages
import os


# User-friendly description from README.md
current_directory = os.path.dirname(os.path.abspath(__file__))
try:
    with open(os.path.join(current_directory, 'README.md'), encoding='utf-8') as f:
        long_description = f.read()
except Exception:
    long_description = ''

setup(
    # Name of the package
    name=<name of current directory>,

    # Packages to include into the distribution
    packages=find_packages('.'), 

    # Start with a small number and increase it with every change you make
    # https://semver.org
    version='1.0.0',

    # Chose a license from here: https://help.github.com/articles/licensing-a-repository
    # For example: MIT
    license='',

    # Short description of your library
    description='',

    # Long description of your library
    long_description = long_description,
    long_description_context_type = 'text/markdown',

    # Your name
    author='', 

    # Your email
    author_email='',     

    # Either the link to your github or to your website
    url='',

    # Link from which the project can be downloaded
    download_url='',

    # List of keyword arguments
    keywords=[],

    # List of packages to install with this one
    install_requires=[],

    # https://pypi.org/classifiers/
    classifiers=[]  
)

Content of the generated setup.py:

• automatically fulfilled package name based on the name of the current directory.
• some basic fields to fulfill.
• clarifying comments and links to useful resources.
• automatically inserted description from README.md or an empty string if there is no README.md.

Here is the link to the repository. Fill free to enhance the solution.

first create file name it as footer.xml put this code inside it.

<?xml version="1.0" encoding="utf-8"?>

then create header.xml and put this code inside it.:

happy coding :)

The space before the = is interpreted as part of the name, and the space after it (as well as the quotation marks) are interpreted as part of the value. So the variable you’ve created can be referenced with %location %. If that’s not what you want, remove the extra space(s) in the definition.

Simple way in Java

public void resize(String inputImagePath,
            String outputImagePath, int scaledWidth, int scaledHeight)
            throws IOException {
        // reads input image
        File inputFile = new File(inputImagePath);
        BufferedImage inputImage = ImageIO.read(inputFile);
 
        // creates output image
        BufferedImage outputImage = new BufferedImage(scaledWidth,
                scaledHeight, inputImage.getType());
 
        // scales the input image to the output image
        Graphics2D g2d = outputImage.createGraphics();
        g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
        g2d.dispose();
 
        // extracts extension of output file
        String formatName = outputImagePath.substring(outputImagePath
                .lastIndexOf(".") + 1);
 
        // writes to output file
        ImageIO.write(outputImage, formatName, new File(outputImagePath));
    }

$q = "SHOW TABLES";
$res = mysql_query($q, $con);
if ($res)
while ( $row = mysql_fetch_array($res, MYSQL_ASSOC) )
{
    foreach( $row as $key => $value )
    {
        if ( $value = BTABLE )  // BTABLE IS A DEFINED NAME OF TABLE
            echo "exist";
        else
            echo "not exist";
    }
}

shell_exec returns all of the output stream as a string. exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

See

• http://php.net/manual/en/function.shell-exec.php
• http://php.net/manual/en/function.exec.php

I call *args "star args" or "varargs" and **kwargs "keyword args".

If you named your class with the keyword in Java, your program wouldn't be recognized that it had the main method.

I have used this small snippet. Might be slower but works every time.

for i in 'find . -type f -name "*.jar"'; do
    jar tvf $i | grep "com.foo.bar.MyClass.clss";
    if [ $? -eq 0 ]; then echo $i; fi;
done

Based on acheron55 answer I posted a possible implementation here.
Here is a brief summery of it:

All you have to do, is to keep track of the path through which the target has been reached. A simple way to do it, is to push into the Queue the whole path used to reach a node, rather than the node itself.
The benefit of doing so is that when the target has been reached the queue holds the path used to reach it.
This is also applicable to cyclic graphs, where a node can have more than one parent.

Here is a function that is part of the helpRFunctions package that will return a list of all of the various data types in your data frame, as well as the specific variable names associated with that type.

install.package('devtools') # Only needed if you dont have this installed.
library(devtools)
install_github('adam-m-mcelhinney/helpRFunctions')
library(helpRFunctions)
my.data <- data.frame(y=rnorm(5), 
                  x1=c(1:5), 
                  x2=c(TRUE, TRUE, FALSE, FALSE, FALSE),
                  X3=letters[1:5])
t <- list.df.var.types(my.data)
t$factor
t$integer
t$logical
t$numeric

You could then do something like var(my.data[t$numeric]).

Hope this is helpful!

You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

Does '%' mean either "mod" or "rem" in C?

In C, % is the remainder¹.

..., the result of the / operator is the algebraic quotient with any fractional part discarded ... (This is often called "truncation toward zero".) C11dr §6.5.5 6

The operands of the % operator shall have integer type. C11dr §6.5.5 2

The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder ... C11dr §6.5.5 5

What's the difference between “mod” and “remainder”?

C does not define "mod", such as the integer modulus function used in Euclidean division or other modulo. "Euclidean mod" differs from C's a%b operation when a is negative.

 // a % b
 7 %  3 -->  1  
 7 % -3 -->  1  
-7 %  3 --> -1  
-7 % -3 --> -1   

Modulo as Euclidean division

 7 modulo  3 -->  1  
 7 modulo -3 -->  1  
-7 modulo  3 -->  2  
-7 modulo -3 -->  2   

Candidate modulo code:

int modulo_Euclidean(int a, int b) {
  int m = a % b;
  if (m < 0) {
    // m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
    m = (b < 0) ? m - b : m + b;
  }
  return m;
}

Note about floating point: double fmod(double x, double y), even though called "fmod", it is not the same as Euclidean division "mod", but similar to C integer remainder:

The fmod functions compute the floating-point remainder of x/y. C11dr §7.12.10.1 2

fmod( 7,  3) -->  1.0  
fmod( 7, -3) -->  1.0  
fmod(-7,  3) --> -1.0  
fmod(-7, -3) --> -1.0   

Disambiguation: C also has a similar named function double modf(double value, double *iptr) which breaks the argument value into integral and fractional parts, each of which has the same type and sign as the argument. This has little to do with the "mod" discussion here except name similarity.

[Edit Dec 2020]

For those who want proper functionality in all cases, an improved modulo_Euclidean() that 1) detects mod(x,0) and 2) a good and no UB result with modulo_Euclidean2(INT_MIN, -1). Inspired by 4 different implementations of modulo with fully defined behavior.

int modulo_Euclidean2(int a, int b) {
  if (b == 0) TBD_Code(); // perhaps return -1 to indicate failure?
  if (b == -1) return 0; // This test needed to prevent UB of `INT_MIN % -1`.
  int m = a % b;
  if (m < 0) {
    // m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
    m = (b < 0) ? m - b : m + b;
  }
  return m;
}

¹ Prior to C99, C's definition of % was still the remainder from division, yet then / allowed negative quotients to round down rather than "truncation toward zero". See Why do you get different values for integer division in C89?. Thus with some pre-C99 compilation, % code can act just like the Euclidean division "mod". The above modulo_Euclidean() will work with this alternate old-school remainder too.

Check the Variables section in the Go template docs. A range may declare two variables, separated by a comma. The following should work:

{{ range $key, $value := . }}
   <li><strong>{{ $key }}</strong>: {{ $value }}</li>
{{ end }}

I had the same problem today. I tested for four things, some of them already mentioned here:

1. Are there any values in your child column that don't exist in the parent column (besides NULL, if the child column is nullable)

2. Do child and parent columns have the same datatype?

3. Is there an index on the parent column you are referencing? MySQL seems to require this for performance reasons (http://dev.mysql.com/doc/refman/5.5/en/create-table-foreign-keys.html)

4. And this one solved it for me: Do both tables have identical collation?

I had one table in UTF-8 and the other in iso-something. That didn't work. After changing the iso-table to UTF-8 collation the constraints could be added without problems. In my case, phpMyAdmin didn't even show the child table in iso-encoding in the dropdown for creating the foreign key constraint.

Simple method:

public boolean isBlank(String value) {
    return (value == null || value.equals("") || value.equals("null") || value.trim().equals(""));
}


public boolean isOnlyNumber(String value) {
    boolean ret = false;
    if (!isBlank(value)) {
        ret = value.matches("^[0-9]+$");
    }
    return ret;
}

Including more than one reference to Jquery library is the reason for the error Only Include one reference to the Jquery library and that will resolve the issue

For Active Directory users, an alternative way to do this would be -- assuming all your groups are stored in OU=Groups,DC=CorpDir,DC=QA,DC=CorpName -- to use the query (&(objectCategory=group)(CN=GroupCN)). This will work well for all groups with less than 1500 members. If you want to list all members of a large AD group, the same query will work, but you'll have to use ranged retrieval to fetch all the members, 1500 records at a time.

The key to performing ranged retrievals is to specify the range in the attributes using this syntax: attribute;range=low-high. So to fetch all members of an AD Group with 3000 members, first run the above query asking for the member;range=0-1499 attribute to be returned, then for the member;range=1500-2999 attribute.

You can use jQuery click instead of using onclick attribute, Try the following:

$('table').on('click', 'input[type="button"]', function(e){
   $(this).closest('tr').remove()
})

Demo

private void buttonHook_Click(object sender, EventArgs e)
{
    // Hooks only into specified Keys (here "A" and "B").
    // (***) Use this constructor

    _globalKeyboardHook = new GlobalKeyboardHook(new Keys[] { Keys.A, Keys.B });

    // Hooks into all keys.
    // (***) Or this - not both

    _globalKeyboardHook = new GlobalKeyboardHook();
    _globalKeyboardHook.KeyboardPressed += OnKeyPressed;
}

And then is working fine.

You don't need pip for installing Beautiful Soup - you can just download it and run python setup.py install from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH - if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install)

However, you really should install pip - see How to install pip on Windows for how to do that best (via @MartijnPieters comment)

Use a for..in loop to enumerate an object's properties, but be careful. The enumeration will return properties not just of the object being enumerated, but also from the prototypes of any parent objects.

var myObject = {foo: 'bar'};

for (var name in myObject) {
  alert(name);
}

// results in a single alert of 'foo'

Object.prototype.baz = 'quux';

for (var name in myObject) {
  alert(name);
}

// results in two alerts, one for 'foo' and one for 'baz'

To avoid including inherited properties in your enumeration, check hasOwnProperty():

for (var name in myObject) {
  if (myObject.hasOwnProperty(name)) {
    alert(name);
  }
}

Edit: I disagree with JasonBunting's statement that we don't need to worry about enumerating inherited properties. There is danger in enumerating over inherited properties that you aren't expecting, because it can change the behavior of your code.

It doesn't matter whether this problem exists in other languages; the fact is it exists, and JavaScript is particularly vulnerable since modifications to an object's prototype affects child objects even if the modification takes place after instantiation.

This is why JavaScript provides hasOwnProperty(), and this is why you should use it in order to ensure that third party code (or any other code that might modify a prototype) doesn't break yours. Apart from adding a few extra bytes of code, there is no downside to using hasOwnProperty().

Almost 5 years after only the direct HTML formatting works for images on GitHub and other markdown options still prevent images from loading when specifying some custom sizes even with the wrong dimensions. I prefer to specify the desired width and get the height calculated automatically, for example,

<img src="https://github.com/your_image.png" alt="Your image title" width="250"/>

I had the same problem but it only occurred on the published website on Godaddy. It was no problem in my local host.

The error came from an aspx.cs (code behind file) where I tried to assign a value to a label. It appeared that from within the code behind, that the label Text appears to be null. So all I did with change all my Label Text properties in the ASPX file from Text="" to Text=" ".

The problem disappeared. I don’t know why the error happens from the hosted version but not on my localhost and don’t have time to figure out why. But it works fine now.

As per W3C: DOM permits programs and scripts to dynamically access and update the content, structure and style of XML or HTML documents.

DOM is composed of:

• set of objects/elements
• a structure of how these objects/elements can be combined
• and an interface to access and modify them

Use svn merge:

svn merge -c -[rev num that deleted the file] http://<path to repository>

So an example:

svn merge -c -12345 https://svn.mysite.com/svn/repo/project/trunk
             ^ The negative is important

For TortoiseSVN (I think...)

• Right click in Explorer, go to TortoiseSVN -> Merge...
• Make sure "Merge a range of revisions" is selected, click Next
• In the "Revision range to merge" textbox, specify the revision that removed the file
• Check the "Reverse merge" checkbox, click Next
• Click Merge

That is completely untested, however.

Edited by OP: This works on my version of TortoiseSVN (the old kind without the next button)

• Go to the folder that stuff was delated from
• Right click in Explorer, go to TortoiseSVN -> Merge...
• in the From section enter the revision that did the delete
• in the To section enter the revision before the delete.
• Click "merge"
• commit

The trick is to merge backwards. Kudos to sean.bright for pointing me in the right direction!

Edit: We are using different versions. The method I described worked perfectly with my version of TortoiseSVN.

Also of note is that if there were multiple changes in the commit you are reverse merging, you'll want to revert those other changes once the merge is done before you commit. If you don't, those extra changes will also be reversed.

I'm surprised that I didn't see any mention of Java's Executor framework for this question's answers. One of the main selling points of the Executor framework is so that you don't have do deal with low level threads. Instead, you're dealing with the higher level of abstraction of ExecutorServices. So, instead of manually starting a thread, just execute the executor that wraps a Runnable. Using the single thread executor, the Runnable instance you create will internally be wrapped and executed as a thread.

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
// ...

ExecutorService threadExecutor = Executors.newSingleThreadExecutor();
try {
  threadExecutor.execute(
    new Runnable() {
      @Override
      public void run() {
        System.out.println("blah");
      }
    }
  );
} finally {
    threadExecutor.shutdownNow();
}

For convenience, see the code on JDoodle.

Im using PHP-FPM or multiple php version in my server. On my case i update mysqli value since there is not mysql default socket parameter :

Even, I was looking for the same regex but I wanted to include the all special character and blank spaces too. So here is the regex for that:

^[A-Za-z0-9\s$&+,:;=?@#|'<>.^*()%!-]{0,10}$

I faced a similar issue during work with Ubuntu 16.04 by using Docker. In my case that was a problem with Composer, but error message (and thus the problem) was the same.

Because of minimalist Docker-oriented base image I had missing ca-certificates package and simple apt-get install ca-certificates helped me.

Any checkout of a commit that is not the name of one of your branches will get you a detached HEAD. A SHA1 which represents the tip of a branch still gives a detached HEAD. Only a checkout of a local branch name avoids that mode.

See committing with a detached HEAD

When HEAD is detached, commits work like normal, except no named branch gets updated. (You can think of this as an anonymous branch.)

For example, if you checkout a "remote branch" without tracking it first, you can end up with a detached HEAD.

See git: switch branch without detaching head

Meaning: git checkout origin/main (or origin/master in the old days) would result in:

Note: switching to 'origin/main'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at a1b2c3d My commit message

That is why you should not use git checkout anymore, but the new git switch command.

With git switch, the same attempt to "checkout" (switch to) a remote branch would fail immediately:

git switch origin/main
fatal: a branch is expected, got remote branch 'origin/main'

To add more on git switch:

With Git 2.23 (August 2019), you don't have to use the confusing git checkout command anymore.

git switch can also checkout a branch, and get a detach HEAD, except:

• it has an explicit --detach option

To check out commit HEAD~3 for temporary inspection or experiment without creating a new branch:

git switch --detach HEAD~3
HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits'

• it cannot detached by mistake a remote tracking branch

See:

C:\Users\vonc\arepo>git checkout origin/master
Note: switching to 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

Vs. using the new git switch command:

C:\Users\vonc\arepo>git switch origin/master
fatal: a branch is expected, got remote branch 'origin/master'

If you wanted to create a new local branch tracking a remote branch:

git switch <branch> 

If <branch> is not found but there does exist a tracking branch in exactly one remote (call it <remote>) with a matching name, treat as equivalent to

git switch -c <branch> --track <remote>/<branch>

No more mistake!
No more unwanted detached HEAD!

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

Thanks for all the helpful suggestions. I finally made sure that there are no warnings in my code, but again was getting this warning from sqlite3:

Assuming signed overflow does not occur when assuming that (X - c) <= X is always true

which I fixed by adding the following CFLAG:

You can do this:

@Override
protected Dialog onCreateDialog(int id) {
    String messageDialog;
    String valueOK;
    String valueCancel;
    String titleDialog;
    switch (id) {

    case id:
        titleDialog = itemTitle;
        messageDialog = itemDescription
        valueOK = "OK";            
        return new AlertDialog.Builder(HomeView.this).setTitle(titleDialog).setPositiveButton(valueOK, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                Log.d(this.getClass().getName(), "AlertItem");
            }
        }).setMessage(messageDialog).create(); 

and then call to

showDialog(numbreOfItem);

I found the above link incredibly helpful as it corrected my C# classes by generating them from the JSON that was actually returned.

Then I called :

and everything worked as expected.

Heres what worked for me, had a similar problem on my new laptop which had windows 10.

• Search for "Turn windows features on or off"
• Check "Internet Information Services"
• Check "World Wide Web Services"
• Check "Application Development Features"
• Enable all items under this

try again, now it should work.

I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
Start-Process Notepad.exe -Credential $credential

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

you can even do this by numpy

import numpy as np
np.array(your_list,dtype=float)

this return np array of your list as float

you also can set 'dtype' as int

You can use iconv command under Unix (also available on Windows as libiconv).

After saving as CSV under Excel in the command line put:

iconv -f cp1250 -t utf-8 file-encoded-cp1250.csv > file-encoded-utf8.csv

(remember to replace cp1250 with your encoding).

Works fast and great for big files like post codes database, which cannot be imported to GoogleDocs (400.000 cells limit).

Use type="application/javascript"

In case of HTML5, the type attribute is obsolete, you may remove it. Note: that it defaults to "text/javascript" according to w3.org, so I would suggest to add the "application/javascript" instead of removing it.

http://www.w3.org/TR/html5/scripting-1.html#attr-script-type
The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".

Use "application/javascript", because "text/javascript" is obsolete:

RFC 4329: http://www.rfc-editor.org/rfc/rfc4329.txt

3. Deployed Scripting Media Types and Compatibility

   Various unregistered media types have been used in an ad-hoc fashion to label and exchange programs written in ECMAScript and JavaScript. These include:

   +-----------------------------------------------------+ | text/javascript | text/ecmascript | | text/javascript1.0 | text/javascript1.1 | | text/javascript1.2 | text/javascript1.3 | | text/javascript1.4 | text/javascript1.5 | | text/jscript | text/livescript | | text/x-javascript | text/x-ecmascript | | application/x-javascript | application/x-ecmascript | | application/javascript | application/ecmascript | +-----------------------------------------------------+

Use of the "text" top-level type for this kind of content is known to be problematic. This document thus defines text/javascript and text/
ecmascript but marks them as "obsolete". Use of experimental and
unregistered media types, as listed in part above, is discouraged.
The media types,

  * application/javascript
  * application/ecmascript

which are also defined in this document, are intended for common use and should be used instead.

This document defines equivalent processing requirements for the
types text/javascript, text/ecmascript, and application/javascript.
Use of and support for the media type application/ecmascript is
considerably less widespread than for other media types defined in
this document. Using that to its advantage, this document defines
stricter processing rules for this type to foster more interoperable
processing.

x-javascript is experimental, don't use it.

As Chris said before me, just an a should override. For example:

a { color:red; }
a:hover { color:blue; }
.nav a { color:green; }

In this instance the .nav a would ALWAYS be green, the :hover wouldn't apply to it.

If there's some other rule affecting it, you COULD use !important, but you shouldn't. It's a bad habit to fall into.

.nav a { color:green !important; } /*I'm a bad person and shouldn't use !important */

Then it'll always be green, irrelevant of any other rule.

Although above answers are correct but to make it simple for newbies, all you need to do is set margin, left and right. following code will do it provided that width is set and position is absolute:

margin: 0 auto;
left: 0;
right: 0;

Let's break down your examples one by one.

@media (max-width:632px)

This one is saying for a window with a max-width of 632px that you want to apply these styles. At that size you would be talking about anything smaller than a desktop screen in most cases.

@media screen and (max-width:632px)

This one is saying for a device with a screen and a window with max-width of 632px apply the style. This is almost identical to the above except you are specifying screen as opposed to the other available media types the most common other one being print.

@media only screen and (max-width:632px)

Here is a quote straight from W3C to explain this one.

The keyword ‘only’ can also be used to hide style sheets from older user agents. User agents must process media queries starting with ‘only’ as if the ‘only’ keyword was not present.

As there is no such media type as "only", the style sheet should be ignored by older browsers.

Here's the link to that quote that is shown in example 9 on that page.

Hopefully this sheds some light on media queries.

EDIT:

Be sure to check out @hybrids excellent answer on how the only keyword is really handled.

You can put the img tag in a div tag and do both, but I would recommend against scaling images in the browser. It does a lousy job most of the time because browsers have very simplistic scaling algorithms. Better to do your scaling in Photoshop or ImageMagick first, then serve it up to the client nice and pretty.

It should be pretty obvious from your question that you're actually just asking about the difference between git merge and git rebase.

So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:

- o - o - o - H - A - B - C (master)
               \
                P - Q - R (origin/master)

If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:

- o - o - o - H - A - B - C - X (master)
               \             /
                P - Q - R --- (origin/master)

If on the other hand you did the appropriate rebase, you'd end up with this:

- o - o - o - H - P - Q - R - A' - B' - C' (master)
                          |
                          (origin/master)

The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R), instead of where you originally committed (H). You should never use the rebase approach if someone else has already pulled from your master branch.

Finally, note that you can actually set up git pull for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase to true. You can also do this for a single pull using git pull --rebase.

If you don't want to change your database schema (and I would not for this simple query) you can just combine them in the filter like this: WHERE (Address1 + Address2) LIKE '%searchstring%'

There is a "3 of 9" control on CodeProject: Barcode .NET Control

There are two operators in Python for the "not equal" condition -

a.) != If values of the two operands are not equal, then the condition becomes true. (a != b) is true.

b.) <> If values of the two operands are not equal, then the condition becomes true. (a <> b) is true. This is similar to the != operator.

Some of us are referring to use from which is not good at the performance:

function getArrayViaFrom(input) {_x000D_
  console.time('Execution Time');_x000D_
  let output = Array.from(Array(input), (value, i) => (i + 1).toString())_x000D_
  console.timeEnd('Execution Time');_x000D_
_x000D_
  return output;_x000D_
}_x000D_
_x000D_
function getArrayViaFor(input) {_x000D_
  console.time('Execution Time 1');_x000D_
  var output = [];_x000D_
  for (var i = 1; i <= input; i++) {_x000D_
    output.push(i.toString());_x000D_
  }_x000D_
  console.timeEnd('Execution Time 1');_x000D_
_x000D_
  return output;_x000D_
}_x000D_
_x000D_
console.log(getArrayViaFrom(10)) // Takes 10x more than for that is 0.220ms_x000D_
console.log(getArrayViaFor(10))  // Takes 10x less than From that is 0.020ms

Think that JavaScriptDevelopmentTools might do it. Although, I have eclipse indigo, and I'm pretty sure it does that kind of thing automatically.

Do you need a type attribute at all? If you're using HTML5, no. Otherwise, yes. HTML 4.01 and XHTML 1.0 specifies the type attribute as required while HTML5 has it as optional, defaulting to text/javascript. HTML5 is now widely implemented, so if you use the HTML5 doctype, <script>...</script> is valid and a good choice.

As to what should go in the type attribute, the MIME type application/javascript registered in 2006 is intended to replace text/javascript and is supported by current versions of all the major browsers (including Internet Explorer 9). A quote from the relevant RFC:

This document thus defines text/javascript and text/ecmascript but marks them as "obsolete". Use of experimental and unregistered media types, as listed in part above, is discouraged. The media types,

  * application/javascript
  * application/ecmascript

which are also defined in this document, are intended for common use and should be used instead.

However, IE up to and including version 8 doesn't execute script inside a <script> element with a type attribute of either application/javascript or application/ecmascript, so if you need to support old IE, you're stuck with text/javascript.

HTML:

<button onclick="scrollToTop(1000);"></button>

1# JavaScript (linear):

function scrollToTop (duration) {
    // cancel if already on top
    if (document.scrollingElement.scrollTop === 0) return;

    const totalScrollDistance = document.scrollingElement.scrollTop;
    let scrollY = totalScrollDistance, oldTimestamp = null;

    function step (newTimestamp) {
        if (oldTimestamp !== null) {
            // if duration is 0 scrollY will be -Infinity
            scrollY -= totalScrollDistance * (newTimestamp - oldTimestamp) / duration;
            if (scrollY <= 0) return document.scrollingElement.scrollTop = 0;
            document.scrollingElement.scrollTop = scrollY;
        }
        oldTimestamp = newTimestamp;
        window.requestAnimationFrame(step);
    }
    window.requestAnimationFrame(step);
}

2# JavaScript (ease in and out):

function scrollToTop (duration) {
    // cancel if already on top
    if (document.scrollingElement.scrollTop === 0) return;

    const cosParameter = document.scrollingElement.scrollTop / 2;
    let scrollCount = 0, oldTimestamp = null;

    function step (newTimestamp) {
        if (oldTimestamp !== null) {
            // if duration is 0 scrollCount will be Infinity
            scrollCount += Math.PI * (newTimestamp - oldTimestamp) / duration;
            if (scrollCount >= Math.PI) return document.scrollingElement.scrollTop = 0;
            document.scrollingElement.scrollTop = cosParameter + cosParameter * Math.cos(scrollCount);
        }
        oldTimestamp = newTimestamp;
        window.requestAnimationFrame(step);
    }
    window.requestAnimationFrame(step);
}
/* 
  Explanation:
  - pi is the length/end point of the cosinus intervall (see below)
  - newTimestamp indicates the current time when callbacks queued by requestAnimationFrame begin to fire.
    (for more information see https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame)
  - newTimestamp - oldTimestamp equals the delta time

    a * cos (bx + c) + d                        | c translates along the x axis = 0
  = a * cos (bx) + d                            | d translates along the y axis = 1 -> only positive y values

  = cosParameter + cosParameter * (cos bx)  | b stretches along the x axis = scrollCount = Math.PI / (scrollDuration / (newTimestamp - oldTimestamp))
  = cosParameter + cosParameter * (cos scrollCount * x)

Note:

• Duration in milliseconds (1000ms = 1s)
• Second script uses the cos function. Example curve:

I had to do the same thing and this is what I wrote.I made it more flexible in my case as I had multiple group of check boxes to check.

// param: reqNum number of checkboxes to select
$.fn.checkboxValidate = function(reqNum){
    var fields = this.serializeArray();
    return (fields.length < reqNum) ? 'invalid' : 'valid';
}

then you can pass this function to check multiple group of checkboxes with multiple rules.

// helper function to create error
function err(msg){
    alert("Please select a " + msg + " preference.");
}

$('#reg').submit(function(e){
    //needs at lease 2 checkboxes to be selected
    if($("input.region, input.music").checkboxValidate(2) == 'invalid'){
        err("Region and Music");
    } 
});

There is no sudo command in case of windows and also there is no need to put any $. For installing Angular CLI through node.js command prompt in windows, I just wrote npm install -g @angular/cli and then pressed Enter. It worked fine.

Based on my own testing and the OP's comments, I think at some point they goofed on the casing of the branch name.

First, I believe the OP is on a case insensitive operating system like OS X or Windows. Then they did something like this...

$ git checkout -b SQLMigration/ReportFixes
Switched to a new branch 'SQLMigration/ReportFixes'

$ git push origin SqlMigration/ReportFixes
fatal: SqlMigration/ReportFixes cannot be resolved to branch.

Note the casing difference. Also note the error is very different from if you just typo the name.

$ git push origin SQLMigration/ReportFixme
error: src refspec SQLMigration/ReportFixme does not match any.
error: failed to push some refs to '[email protected]:schwern/testing123.git'

Because Github uses the filesystem to store branch names, it tries to open .git/refs/heads/SqlMigration/ReportFixes. Because the filesystem is case insensitive it successfully opens .git/refs/heads/SqlMigration/ReportFixes but gets confused when it tries to compare the branch names case-sensitively and they don't match.

How they got into a state where the local branch is SQLMigration/ReportFixes and the remote branch is SqlMigration/ReportFixes I'm not sure. I don't believe Github messed with the remote branch name. Simplest explanation is someone else with push access changed the remote branch name. Otherwise, at some point they did something which managed to create the remote with the typo. If they check their shell history, perhaps with history | grep -i sqlmigration/reportfixes they might be able to find a command where they mistyped the casing.

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

Check on yourCheckBox.Value ?

You need to escape the backslash \:

println yourString.replace("\\", "/")

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html

use Jquery or something here is example

of it http://riderdesign.com/articles/Check-username-availability-with-JQuery-and-ASP.NET.aspx i hope i will help you more

$sql="SELECT tot_visit FROM visitors WHERE date = DATE(NOW()) - 1 into @s                
$conn->query($sql);
$sql = "INSERT INTO visitors (nbvisit_day,date,tot_visit) VALUES (1,CURRENT_DATE,@s+1)";
$conn->query($sql);

While ireport does not officially support java8, there is a fairly simple way to make ireport (tested with ireport 5.1) work with Java 8. The problem is actually in netbeans. There is a very simple patch, assuming you don't care about the improved security in Java 8:

http://hg.netbeans.org/jet-main/diff/3238e03c676f/openide.util/src/org/openide/util/WeakListenerImpl.java

I didn't even use the exact netbeans source used by ireport. I just downloaded the latest WeakListenerImpl.java in full from the above repository, and compiled it in the ireport directory with platform9/lib/org-openide-util.jar in the compiler classpath

cd blah/blah/iReport-5.1.0
wget http://hg.netbeans.org/jet-main/raw-file/3238e03c676f/openide.util/src/org/openide/util/WeakListenerImpl.java
javac -d . -cp platform9/lib/org-openide-util.jar WeakListenerImpl.java
zip -r platform9/lib/org-openide-util.jar org

I am avoiding running eclipse just to edit jasper reports as long as I can. The netbeans based ireport is so much lighter weight. Running Eclipse is like using emacs.

What you can do is create a new column over on the right side of your spreadsheet that you'll use to compute a value you can base your shading on.

Let's say your new column is column D, and the value you want to look at is in column A starting in row 2.

In cell D2 put: =MOD(IF(ROW()=2,0,IF(A2=A1,D1, D1+1)), 2)

Fill that down as far as you need, (then hide the column if you want).

Now highlight your entire data set - this selection of cells will be the ones that get shaded in the next step.

From the Home tab, click Conditional Formatting, then New Rule.

Select Use a formula to determine which cells to format.

In "Format values where this formula is true" put =$D2=1

Click the Format button, click the Fill tab, then choose the color you want to shade with.

If you have a problem in Android Studio and you have installed Android N, change the Android rendering version with an older one and the problem will disappear.

We can use ls and many other Linux commands in Windows cmd. Just follow these steps.

Steps:

1) Install Git in your computer - https://git-scm.com/downloads.

2) After installing Git, go to the folder in which Git is installed. Mostly it will be in C drive and then Program Files Folder.

3) In Program Files folder, you will find the folder named Git, find the bin folder which is inside usr folder in the Git folder.

In my case, the location for bin folder was - C:\Program Files\Git\usr\bin

4) Add this location (C:\Program Files\Git\usr\bin) in path variable, in system environment variables.

5) You are done. Restart cmd and try to run ls and other Linux commands.

Try this :

var name = $("#txtname").val();
alert(name);

Seen a lot of recommendations to use a ConcurrentDictionary, but no solid examples of it, so I'm going to throw my hat into this solution race. I'm not a thread-safe developer, so if this code isn't solid, please speak up for the sake of those who follow after.

public static class XmlSerializerHelper
{
    private static readonly ConcurrentDictionary<Type, XmlSerializer> TypeSerializers = new ConcurrentDictionary<Type, XmlSerializer>();

    public static XmlSerializer GetSerializer(Type type)
    {
        return TypeSerializers.GetOrAdd(type,
        t =>
        {
            var importer = new XmlReflectionImporter();
            var mapping = importer.ImportTypeMapping(t, null, null);
            return new XmlSerializer(mapping);
        });
    }
}

I've seen other posts involving ConcurrentDictionary and Lazy loading the value. I'm not sure if that's relevant here or not, but here's the code for that:

private static readonly ConcurrentDictionary<Type, Lazy<XmlSerializer>> TypeSerializers = new ConcurrentDictionary<Type, Lazy<XmlSerializer>>();

public static XmlSerializer GetSerializer(Type type)
{
    return TypeSerializers.GetOrAdd(type,
    t =>
    {
        var importer = new XmlReflectionImporter();
        var mapping = importer.ImportTypeMapping(t, null, null);
        var lazyResult = new Lazy<XmlSerializer>(() => new XmlSerializer(mapping), LazyThreadSafetyMode.ExecutionAndPublication);
        return lazyResult;
    }).Value;
}

Try PDFMiner. It can extract text from PDF files as HTML, SGML or "Tagged PDF" format.

The Tagged PDF format seems to be the cleanest, and stripping out the XML tags leaves just the bare text.

A Python 3 version is available under:

Always use tax_query to get posts/products from a particular category or any other taxonomy. You can also get the products using ID/slug of particular taxonomy...

$the_query = new WP_Query( array(
    'post_type' => 'product',
    'tax_query' => array(
        array (
            'taxonomy' => 'product_cat',
            'field' => 'slug',
            'terms' => 'accessories',
        )
    ),
) );

while ( $the_query->have_posts() ) :
    $the_query->the_post();
    the_title(); echo "<br>";
endwhile;


wp_reset_postdata();

Assign a new Image object to your PictureBox's Image property. To load an Image from a file, you may use the Image.FromFile method. In your particular case, assuming the current directory is one under bin, this should load the image bin/Pics/image1.jpg, for example:

pictureBox1.Image = Image.FromFile("../Pics/image1.jpg");

Additionally, if these images are static and to be used only as resources in your application, resources would be a much better fit than files.

You can use following code snippet for get the HttpClient instance without ssl certification checking.

private HttpClient getSSLHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

        LogLoader.serverLog.trace("In getSSLHttpClient()");

        SSLContext context = SSLContext.getInstance("SSL");

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        context.init(null, new TrustManager[] { tm }, null);

        HttpClientBuilder builder = HttpClientBuilder.create();
        SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context);
        builder.setSSLSocketFactory(sslConnectionFactory);

        PlainConnectionSocketFactory plainConnectionSocketFactory = new PlainConnectionSocketFactory();
        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("https", sslConnectionFactory).register("http", plainConnectionSocketFactory).build();

        PoolingHttpClientConnectionManager ccm = new PoolingHttpClientConnectionManager(registry);
        ccm.setMaxTotal(BaseConstant.CONNECTION_POOL_SIZE);
        ccm.setDefaultMaxPerRoute(BaseConstant.CONNECTION_POOL_SIZE);
        builder.setConnectionManager((HttpClientConnectionManager) ccm);

        builder.disableRedirectHandling();

        LogLoader.serverLog.trace("Out getSSLHttpClient()");

        return builder.build();
    }

For this, you need to declare the variable as global. However, a global variable is also accessible from outside the module by using module_name.var_name. Add this as the first line of your module:

global __DBNAME__

Using Accept header is really easy to get the format json or xml from the REST service.

This is my Controller, take a look produces section.

@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
    public UIProperty getProperties() {
        return uiProperty;
    }

In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE

HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);

HttpEntity entity = new HttpEntity(headers);

RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();

Edit 01:

In order to work with application/xml, add this dependency

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>

If your log4j.properties or log4j.xml file not found under src/main/resources use this PropertyConfigurator.configure("log4j.xml");

   PropertyConfigurator.configure("log4j.xml");
   Logger logger = LoggerFactory.getLogger(MyClass.class);
   logger.error(message);

I had buildToolsVersion "27.0.1", upgrading it to 27.0.2 fixed the issue.

Also, my android support deps were at version 27.0.2 so they were not aligned to the buildToolsVersion

This will do it if you only want the first "B" value, you can sub a cell address for "B" if you want to make it more generic.

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(B2:B6)="B",0)),1)

To use this based on two columns, just concatenate inside the match:

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(A2:A6&B2:B6)=("3"&"B"),0)),1)

The idea is that the response body gives you a page that links you to the thing:

201 Created

The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location field is received, by the effective request URI.

This means that you would include a Location in the response header that gives the URL of where you can find the newly created thing:

HTTP/1.1 201 Created
Date: Sat, 02 Apr 2016 12:22:40 GMT
Location: http://stackoverflow.com/a/36373586/12597

Response body

They then go on to mention what you should include in the response body:

The 201 response payload typically describes and links to the resource(s) created.

For the human using the browser, you give them something they can look at, and click, to get to their newly created resource:

      "http://stackoverflow.com/a/36373586/12597"
   ]
}

The response is entirely up to you; it's arbitrarily what you'd like.

Cache friendly

Finally there's the optimization that I can pre-cache the created resource (because I already have the content; I just uploaded it). The server can return a date or ETag which I can store with the content I just uploaded:

See Section 7.2 for a discussion of the meaning and purpose of validator header fields, such as ETag and Last-Modified, in a 201 response.

And ETag s are purely arbitrary values. Having them be different when a resource changes (and caches need to be updated) is all that matters. The ETag is usually a hash (e.g. SHA2). But it can be a database rowversion, or an incrementing revision number. Anything that will change when the thing changes.

I made a full demostration that works in every browser with the full source code of the solution of this problem: Coordinates of a mouse click on Canvas in Javascript. To try the demo, copy the code and paste it into a text editor. Then save it as example.html and, finally, open the file with a browser.

Yes, this is possible. One of the main pros for using Swing is the ease with which the abstract controls can be created and manipulates.

Here is a quick and dirty way to extend the existing JButton class to draw a circle to the right of the text.

package test;

import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Graphics;

import javax.swing.JButton;
import javax.swing.JFrame;

public class MyButton extends JButton {

    private static final long serialVersionUID = 1L;

    private Color circleColor = Color.BLACK;

    public MyButton(String label) {
        super(label);
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        Dimension originalSize = super.getPreferredSize();
        int gap = (int) (originalSize.height * 0.2);
        int x = originalSize.width + gap;
        int y = gap;
        int diameter = originalSize.height - (gap * 2);

        g.setColor(circleColor);
        g.fillOval(x, y, diameter, diameter);
    }

    @Override
    public Dimension getPreferredSize() {
        Dimension size = super.getPreferredSize();
        size.width += size.height;
        return size;
    }

    /*Test the button*/
    public static void main(String[] args) {
        MyButton button = new MyButton("Hello, World!");

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);

        Container contentPane = frame.getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(button);

        frame.setVisible(true);
    }

}

Note that by overriding paintComponent that the contents of the button can be changed, but that the border is painted by the paintBorder method. The getPreferredSize method also needs to be managed in order to dynamically support changes to the content. Care needs to be taken when measuring font metrics and image dimensions.

For creating a control that you can rely on, the above code is not the correct approach. Dimensions and colours are dynamic in Swing and are dependent on the look and feel being used. Even the default Metal look has changed across JRE versions. It would be better to implement AbstractButton and conform to the guidelines set out by the Swing API. A good starting point is to look at the javax.swing.LookAndFeel and javax.swing.UIManager classes.

http://docs.oracle.com/javase/8/docs/api/javax/swing/LookAndFeel.html

Understanding the anatomy of LookAndFeel is useful for writing controls: Creating a Custom Look and Feel

Here is a prototype to convert a number to a readable string respecting the new international standards.

There are two ways to represent big numbers: You could either display them in multiples of 1000 = 10 3 (base 10) or 1024 = 2 10 (base 2). If you divide by 1000, you probably use the SI prefix names, if you divide by 1024, you probably use the IEC prefix names. The problem starts with dividing by 1024. Many applications use the SI prefix names for it and some use the IEC prefix names. The current situation is a mess. If you see SI prefix names you do not know whether the number is divided by 1000 or 1024

https://wiki.ubuntu.com/UnitsPolicy

http://en.wikipedia.org/wiki/Template:Quantities_of_bytes

Object.defineProperty(Number.prototype,'fileSize',{value:function(a,b,c,d){
 return (a=a?[1e3,'k','B']:[1024,'K','iB'],b=Math,c=b.log,
 d=c(this)/c(a[0])|0,this/b.pow(a[0],d)).toFixed(2)
 +' '+(d?(a[1]+'MGTPEZY')[--d]+a[2]:'Bytes');
},writable:false,enumerable:false});

This function contains no loop, and so it's probably faster than some other functions.

Usage:

IEC prefix

console.log((186457865).fileSize()); // default IEC (power 1024)
//177.82 MiB
//KiB,MiB,GiB,TiB,PiB,EiB,ZiB,YiB

SI prefix

console.log((186457865).fileSize(1)); //1,true for SI (power 1000)
//186.46 MB 
//kB,MB,GB,TB,PB,EB,ZB,YB

i set the IEC as default because i always used binary mode to calculate the size of a file... using the power of 1024

If you just want one of them in a short oneliner function:

SI

function fileSizeSI(a,b,c,d,e){
 return (b=Math,c=b.log,d=1e3,e=c(a)/c(d)|0,a/b.pow(d,e)).toFixed(2)
 +' '+(e?'kMGTPEZY'[--e]+'B':'Bytes')
}
//kB,MB,GB,TB,PB,EB,ZB,YB

IEC

function fileSizeIEC(a,b,c,d,e){
 return (b=Math,c=b.log,d=1024,e=c(a)/c(d)|0,a/b.pow(d,e)).toFixed(2)
 +' '+(e?'KMGTPEZY'[--e]+'iB':'Bytes')
}
//KiB,MiB,GiB,TiB,PiB,EiB,ZiB,YiB

Usage:

console.log(fileSizeIEC(7412834521));

if you have some questions about the functions just ask

The accepted answer explained the problem well enough. However, the more Numpythonic approach for applying multiple conditions is to use numpy logical functions. In this case, you can use np.logical_and:

np.where(np.logical_and(np.greater_equal(dists,r),np.greater_equal(dists,r + dr)))

If your problem is like the following while using Google Chrome:

[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]

Then create a batch file by following these steps:

Open notepad in Desktop.

1. Just copy and paste the followings in your currently opened notepad file:

start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit

1. Note: In the previous line, Replace the full absolute address with your location of chrome installation. [To find it...Right click your short cut of chrome.exe link or icon and Click on Properties and copy-paste the target link][Remember : start to files in one line, & exit in another line by pressing enter]
2. Save the file as fileName.bat [Very important: .bat]
3. If you want to change the file later then right-click on the .bat file and click on edit. After modifying, save the file.

This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.

Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.

int random(int min, int max) //range : [min, max]
{
   static bool first = true;
   if (first) 
   {  
      srand( time(NULL) ); //seeding for the first time only!
      first = false;
   }
   return min + rand() % (( max + 1 ) - min);
}

You can try to get the list of all elements with class = "content" by using find_elements_by_class_name:

a = driver.find_elements_by_class_name("content")

Then you can click on the link that you are looking for.

All you need to do is annotate a method that returns a DataSource with @Bean. A complete working example follows.

@Bean
public DataSource dataSource() {
    DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
        dataSourceBuilder.url(dbUrl);
        dataSourceBuilder.username(username);
        dataSourceBuilder.password(password);
        return dataSourceBuilder.build();   
}

Using netsh with connectaddress=127.0.0.1 did not work for me.

Despite looking everywhere on the internet I could not find the solution which solved this for me, which was to use connectaddress=127.x.x.x (i.e. any 127. ipv4 address, just not 127.0.0.1) as this appears to link back to localhost just the same but without the restriction, so that the loopback works in netsh.

Do you want it to match "(b)"? Do as Zitrax and Paolo have suggested. Do you want it to match "b"? Do

>>> x = "a (b) c (d) e"
>>> re.search(r"\((.*?)\)", x).group(1)
'b'

I have tried these methods and find that they dont work for my needs. In my case, I needed to inject json rendered server side into the main template of the page, so when it loads and angular inits, the data is already there and doesnt have to be retrieved (large dataset).

The easiest solution that I have found is to do the following:

In your angular code outside of the app, module and controller definitions add in a global javascript value - this definition MUST come before the angular stuff is defined.

Example:

'use strict';

//my data variable that I need access to.
var data = null;

angular.module('sample', [])

Then in your controller:

.controller('SampleApp', function ($scope, $location) {

$scope.availableList = [];

$scope.init = function () {
    $scope.availableList = data;
}

Finally, you have to init everything (order matters):

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
  <script src="/path/to/your/angular/js/sample.js"></script>
  <script type="text/javascript">
      data = <?= json_encode($cproducts); ?>
  </script>

Finally initialize your controller and init function.

  <div ng-app="samplerrelations" ng-controller="SamplerApp" ng-init="init();">

By doing this you will now have access to whatever data you stuffed into the global variable.

You can use the AND or OR operators, depending on what you want the search to return.

SELECT title FROM pages WHERE my_col LIKE %$param1% AND another_col LIKE %$param2%;

Both clauses have to match for a record to be returned. Alternatively:

SELECT title FROM pages WHERE my_col LIKE %$param1% OR another_col LIKE %$param2%;

If either clause matches then the record will be returned.

For more about what you can do with MySQL SELECT queries, try the documentation.

This is worked for me

$('<div>We failed</div>')
    .dialog(
    {
        title: 'Error',
        close: function(event, ui)
        {
            $(this).dialog("close");
            $(this).remove();
        }
    });

Cheers!

PS: I had a somewhat similar problem and the above approach solved it.

Having a table with a foreign key to itself does make sense to me.

You can then use a common table expression in SQL or the connect by prior statement in Oracle to build your tree.

The configuration way

IPython has profiles for configuration, located at ~/.ipython/profile_*. The default profile is called profile_default. Within this folder there are two primary configuration files:

• ipython_config.py
• ipython_kernel_config.py

Add the inline option for matplotlib to ipython_kernel_config.py:

c = get_config()
# ... Any other configurables you want to set
c.InteractiveShellApp.matplotlib = "inline"

matplotlib vs. pylab

Usage of %pylab to get inline plotting is discouraged.

It introduces all sorts of gunk into your namespace that you just don't need.

%matplotlib on the other hand enables inline plotting without injecting your namespace. You'll need to do explicit calls to get matplotlib and numpy imported.

import matplotlib.pyplot as plt
import numpy as np

The small price of typing out your imports explicitly should be completely overcome by the fact that you now have reproducible code.

It's just the method. You're not missing anything. The official documentation shows that you can use list unpacking to supply several paths:

s = "c:/,home,foo,bar,some.txt".split(",")
os.path.join(*s)

Note the *s intead of just s in os.path.join(*s). Using the asterisk will trigger the unpacking of the list, which means that each list argument will be supplied to the function as a separate argument.

Say the table is user(id, user_name, user_email).

You can use this query:

INSERT INTO user (SELECT NULL,user_name, user_email FROM user WHERE id = 1)

Vlookup is good if the reference values (column A, sheet 1) are in ascending order. Another option is Index and Match, which can be used no matter the order (As long as the values in column a, sheet 1 are unique)

This is what you would put in column B on sheet 2

=INDEX(Sheet1!A$1:B$6,MATCH(A1,Sheet1!A$1:A$6),2)

Setting Sheet1!A$1:B$6 and Sheet1!A$1:A$6 as named ranges makes it a little more user friendly.

If you're looking for a solution that seems to be more "by the book" and methodologically designed (using a BroadcastReceiver), you better have a look at the following link: http://www.hrupin.com/2011/10/how-to-finish-all-activities-in-your-android-application-through-simple-call.

A slight change is required in the proposed implementation that appears in that link - you should use the sendStickyBroadcast(Intent) method (don't forget to add the BROADCAST_STICKY permission to your manifest) rather than sendBroadcast(Intent), in order to enable your paused activities to be able to receive the broadcast and process it, and this means that you should also remove that sticky broadcast while restarting your application by calling the removeStickyBroadcast(Intent) method in your opening Activity's onCreate() method.

Although the above mentioned startActivity(...) based solutions, at first glance - seem to be very nice, elegant, short, fast and easy to implement - they feel a bit "wrong" (to start an activity - with all the possible overhead and resources that may be required and involved in it, just in order to kill it?...)

This question has been asked and answered many times:

Read file from serial port using Java

Reading serial port in Java

Reading file from serial port in Java

Is there Java library or framework for accessing Serial ports?

Java Serial Communication on Windows

to reference a few.

Personally I recommend SerialPort from http://serialio.com - it's not free, but it's well worth the developer (no royalties) licensing fee for any commercial project. Sadly, it is no longer royalty free to deploy, and SerialIO.com seems to have remade themselves as a hardware seller; I had to search for information on SerialPort.

From personal experience, I strongly recommend against the Sun, IBM and RxTx implementations, all of which were unstable in 24/7 use. Refer to my answers on some of the aforementioned questions for details. To be perfectly fair, RxTx may have come a long way since I tried it, though the Sun and IBM implementations were essentially abandoned, even back then.

A newer free option that looks promising and may be worth trying is jSSC (Java Simple Serial Connector), as suggested by @Jodes comment.
