In my case append only this line worked

SetOutputFilter DEFLATE

If you need this procedure for variable fieldnames instead of id this might be helpful:

DROP PROCEDURE IF EXISTS update_auto_increment;
DELIMITER //
CREATE PROCEDURE update_auto_increment (_table VARCHAR(128), _fieldname VARCHAR(128))
BEGIN
    DECLARE _max_stmt VARCHAR(1024);
    DECLARE _stmt VARCHAR(1024);    
    SET @inc := 0;

    SET @MAX_SQL := CONCAT('SELECT IFNULL(MAX(',_fieldname,'), 0) + 1 INTO @inc FROM ', _table);
    PREPARE _max_stmt FROM @MAX_SQL;
    EXECUTE _max_stmt;
    DEALLOCATE PREPARE _max_stmt;

    SET @SQL := CONCAT('ALTER TABLE ', _table, ' AUTO_INCREMENT =  ', @inc);
    PREPARE _stmt FROM @SQL;
    EXECUTE _stmt;
    DEALLOCATE PREPARE _stmt;
END //
DELIMITER ;

CALL update_auto_increment('your_table_name', 'autoincrement_fieldname');

I have Had the same issue and the only Solution i found was open Package manager> Select Microsoft and .Net as Package Source and You will install it..

Bearer token is one or more repetition of alphabet, digit, "-" , "." , "_" , "~" , "+" , "/" followed by 0 or more "=".

RFC 6750 2.1. Authorization Request Header Field (Format is ABNF (Augmented BNF))

The syntax for Bearer credentials is as follows:

     b64token    = 1*( ALPHA / DIGIT /
                       "-" / "." / "_" / "~" / "+" / "/" ) *"="
     credentials = "Bearer" 1*SP b64token

It looks like Base64 but according to Should the token in the header be base64 encoded?, it is not.

Digging a bit deeper in to "HTTP/1.1, part 7: Authentication"**, however, I see that b64token is just an ABNF syntax definition allowing for characters typically used in base64, base64url, etc.. So the b64token doesn't define any encoding or decoding but rather just defines what characters can be used in the part of the Authorization header that will contain the access token.

This fully addresses the first 3 items in the OP question's list. So I'm extending this answer to address the 4th question, about whether the token must be validated, so @mon feel free to remove or edit:

The authorizer is responsible for accepting or rejecting the http request. If the authorizer says the token is valid, it's up to you to decide what this means:

• Does the authorizer have a way of inspecting the URL, identifying the operation, and looking up some role-based access control database to see if it is allowed? If yes and the request comes through, the service can assume it is allowed, and does not need to verify.
• Is the token an all-or-nothing, so if the token is correct, all operations are allowed? Then the service doesn't need to verify.
• Does the token mean "this request is allowed, but here is the UUID for the role, you check whether the operation is allowed". Then it's up to the service to look up that role, and see if the operation is allowed.

This is a complete solution. I've just updated this example code with the information provided in the answer below by @mad. Also check the solution below from @Khobaib explaining how to deal with picasa images.

Update

I've just reviewed my original answer and created a simple Android Studio project you can checkout from github and import directly on your system.

Selecting Multiple Pictures

Since someone requested that information in a comment and it's better to have information gathered.

Set an extra parameter EXTRA_ALLOW_MULTIPLE on the intent:

intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

And in the Result handling check for that parameter:

if (Intent.ACTION_SEND_MULTIPLE.equals(data.getAction()))
        && Intent.hasExtra(Intent.EXTRA_STREAM)) {
    // retrieve a collection of selected images
    ArrayList<Parcelable> list = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
    // iterate over these images
    if( list != null ) {
       for (Parcelable parcel : list) {
         Uri uri = (Uri) parcel;
         // TODO handle the images one by one here
       }
   }
} 

Note that this is only supported by API level 18+.

What's important is which mechanism you are using the send the email. Most modern libraries (i.e. System.Net.Mail) will hide the folding from you. You just put a very long email subject line in without (CR,LF,HTAB). If you start trying to do your own folding all bets are off. It will start reporting errors. So if you are having this issue just filter out the CR,LF,HTAB and let the library do the work for you. You can usually also set the encoding text type as a separate field. No need for iso encoding in the subject line.

For completeness with os.scandir (2x faster over pathlib):

import os
sorted(os.scandir('/tmp/test'), key=lambda d: d.stat().st_mtime)

I took Crystalonics' answer and turned them into extension methods. I hope someone else will find them useful:

public static byte[] SerializeToByteArray(this object obj)
{
    if (obj == null)
    {
        return null;
    }
    var bf = new BinaryFormatter();
    using (var ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

public static T Deserialize<T>(this byte[] byteArray) where T : class
{
    if (byteArray == null)
    {
        return null;
    }
    using (var memStream = new MemoryStream())
    {
        var binForm = new BinaryFormatter();
        memStream.Write(byteArray, 0, byteArray.Length);
        memStream.Seek(0, SeekOrigin.Begin);
        var obj = (T)binForm.Deserialize(memStream);
        return obj;
    }
}

Certainly, how it's done depends on your shell. In Bash, you can use single quotes around the message and can just leave the quote open, which will make Bash prompt for another line, until you close the quote. Like this:

git commit -m 'Message

goes
here'

Alternatively, you can use a "here document" (also known as heredoc):

git commit -F- <<EOF
Message

goes
here
EOF

Using

Dim myarray As Variant

works but

Dim myarray As String

doesn't so I sitck to Variant

Ok, Here's what I found out.

What I didn't understand is that all fragments that are attached to an activity when a config change happens (phone rotates) are recreated and added back to the activity. (which makes sense)

What was happening in the TabListener constructor was the tab was detached if it was found and attached to the activity. See below:

mFragment = mActivity.getFragmentManager().findFragmentByTag(mTag);
    if (mFragment != null && !mFragment.isDetached()) {
        Log.d(TAG, "constructor: detaching fragment " + mTag);
        FragmentTransaction ft = mActivity.getFragmentManager().beginTransaction();
        ft.detach(mFragment);
        ft.commit();
    }

Later in the activity onCreate the previously selected tab was selected from the saved instance state. See below:

if (savedInstanceState != null) {
    bar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
    Log.d(TAG, "FragmentTabs.onCreate tab: " + savedInstanceState.getInt("tab"));
    Log.d(TAG, "FragmentTabs.onCreate number: " + savedInstanceState.getInt("number"));
}

When the tab was selected it would be reattached in the onTabSelected callback.

public void onTabSelected(Tab tab, FragmentTransaction ft) {
    if (mFragment == null) {
        mFragment = Fragment.instantiate(mActivity, mClass.getName(), mArgs);
        Log.d(TAG, "onTabSelected adding fragment " + mTag);
        ft.add(android.R.id.content, mFragment, mTag);
    } else {
        Log.d(TAG, "onTabSelected attaching fragment " + mTag);
        ft.attach(mFragment);
    }
}

The fragment being attached is the second call to the onCreateView and onActivityCreated methods. (The first being when the system is recreating the acitivity and all attached fragments) The first time the onSavedInstanceState Bundle would have saved data but not the second time.

The solution is to not detach the fragment in the TabListener constructor, just leave it attached. (You still need to find it in the FragmentManager by it's tag) Also, in the onTabSelected method I check to see if the fragment is detached before I attach it. Something like this:

public void onTabSelected(Tab tab, FragmentTransaction ft) {
            if (mFragment == null) {
                mFragment = Fragment.instantiate(mActivity, mClass.getName(), mArgs);
                Log.d(TAG, "onTabSelected adding fragment " + mTag);
                ft.add(android.R.id.content, mFragment, mTag);
            } else {

                if(mFragment.isDetached()) {
                    Log.d(TAG, "onTabSelected attaching fragment " + mTag);
                    ft.attach(mFragment);
                } else {
                    Log.d(TAG, "onTabSelected fragment already attached " + mTag);
                }
            }
        }

Try this:

 Select 
    Id, 
    Salt, 
    Password, 
    BannedEndDate, 
    (Select Count(*) 
        From LoginFails 
        Where username = '" + LoginModel.Username + "' And IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "')
 From Users 
 Where username = '" + LoginModel.Username + "'

And I recommend you strongly to use parameters in your query to avoid security risks with sql injection attacks!

Hope that helps!

This is quite simple, and I think it was even shown in the tutorial:

>>> listone = [1,2,3]
>>> listtwo = [4,5,6]
>>>
>>> listone + listtwo
[1, 2, 3, 4, 5, 6]

If you have done this to make sure the user can't close the window:

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

Then you should change your pullThePlug() method to be

public void pullThePlug() {
    // this will make sure WindowListener.windowClosing() et al. will be called.
    WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
    Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);

    // this will hide and dispose the frame, so that the application quits by
    // itself if there is nothing else around. 
    setVisible(false);
    dispose();
    // if you have other similar frames around, you should dispose them, too.

    // finally, call this to really exit. 
    // i/o libraries such as WiiRemoteJ need this. 
    // also, this is what swing does for JFrame.EXIT_ON_CLOSE
    System.exit(0); 
}

I found this to be the only way that plays nice with the WindowListener and JFrame.DO_NOTHING_ON_CLOSE.

CAUSE:

The error is happening because your project folder is owned by the root user.

SOLUTION

Change ownership to the currently signed in user and not the root user. If you only have root as the sole user, create another user with root privileges.

$ sudo chown -R current_user /my/project/directory/

then

$ composer install

I experienced this problem today, but unfortunately none of the suggestions here helped. The only problem was that I didn't see ANY errors.. I literally had to do an strace -p <process_id> on the Apache thread to spot the headers being written and Apache crashing on the next line; Somewhere in my PHP code I was setting a header with over 12KB of data.

The lesson here is that in some cases, Apache crashing with a HTTP error 500 - Premature end of script-failure can be the result of having too long or overflowing HTTP headers.

Debug your headers for length if you have this same problems because most (if not all) web servers have HTTP header limits.

PS: This reply has some info on header sizes.

To solve this without jQuery .each() you'd have to fix your code like this:

var listItems = $("#productList").find("li");
var ind, len, product;

for ( ind = 0, len = listItems.length; ind < len; ind++ ) {
    product = $(listItems[ind]);

    // ...
}

Bugs in your original code:

1. for ... in will also loop through all inherited properties; i.e. you will also get a list of all functions that are defined by jQuery.

2. The loop variable li is not the list item, but the index to the list item. In that case the index is a normal array index (i.e. an integer)

Basically you are save to use .each() as it is more comfortable, but espacially when you are looping bigger arrays the code in this answer will be much faster.

For other alternatives to .each() you can check out this performance comparison: http://jsperf.com/browser-diet-jquery-each-vs-for-loop

Use the return keyword.

From MSDN:

The return statement terminates execution of the method in which it appears and returns control to the calling method. It can also return the value of the optional expression. If the method is of the type void, the return statement can be omitted.

So in your case, the usage would be:

private void button1_Click(object sender, EventArgs e)
{
    if (textBox1.Text == "" || textBox2.Text == "" || textBox3.Text == "")
    {
        return; //exit this event
    }
}

I can suggest the following method:

Convert the number to a string ? convert the string into an array of characters ? convert the array of characters into an array of integers

Here comes my code:

public class test {

    public static void main(String[] args) {

        int num1 = 123456; // Example 1
        int num2 = 89786775; // Example 2

        String str1 = Integer.toString(num1); // Converts num1 into String
        String str2 = Integer.toString(num2); // Converts num2 into String

        char[] ch1 = str1.toCharArray(); // Gets str1 into an array of char
        char[] ch2 = str2.toCharArray(); // Gets str2 into an array of char

        int[] t1 = new int[ch1.length]; // Defines t1 for bringing ch1 into it
        int[] t2 = new int[ch2.length]; // Defines t2 for bringing ch2 into it

        for(int i=0;i<ch1.length;i++) // Watch the ASCII table
            t1[i]= (int) ch1[i]-48; // ch1[i] is 48 units more than what we want

        for(int i=0;i<ch2.length;i++) // Watch the ASCII table
            t2[i]= (int) ch2[i]-48; // ch2[i] is 48 units more than what we want
        }
    }

One way would be to just escape the quotes properly:

<input type="button" value="click" id="mybtn"
       onclick="myfunction('/myController/myAction', 
               'myfuncionOnOK(\'/myController2/myAction2\', 
                   \'myParameter2\');',
               'myfuncionOnCancel(\'/myController3/myAction3\', 
                   \'myParameter3\');');">

In this case, though, I think a better way to handle this would be to wrap the two handlers in anonymous functions:

<input type="button" value="click" id="mybtn"
       onclick="myfunction('/myController/myAction', 
                function() { myfuncionOnOK('/myController2/myAction2', 
                             'myParameter2'); },
                function() { myfuncionOnCancel('/myController3/myAction3', 
                             'myParameter3'); });">

And then, you could call them from within myfunction like this:

function myfunction(url, onOK, onCancel)
{
    // Do whatever myfunction would normally do...

    if (okClicked)
    {
        onOK();
    }

    if (cancelClicked)
    {
        onCancel();
    }
}

That's probably not what myfunction would actually look like, but you get the general idea. The point is, if you use anonymous functions, you have a lot more flexibility, and you keep your code a lot cleaner as well.

Remove the width:100%; declarations.

Block elements should take up the whole available width by default.

On linux I have same problem - its not listed in tools.

However there is a small icon:

Vectors and matrices can only be of a single type and cbind and rbind on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.

(Note that in your rbind example, the promotion happens within the c call:

> c(10, "[]", "[[1,2]]")
[1] "10"      "[]"      "[[1,2]]"

If you want a rectangular structure where the columns can be different types, you want a data.frame. Any of the following should get you what you want:

> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
  v1 v2      v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ v1: num  10 20
 $ v2: Factor w/ 1 level "[]": 1 1
 $ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using specifically the data.frame version of cbind)

> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c(10, 20)              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using cbind, but making the first a data.frame so that it combines as data.frames do):

> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c.10..20.              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

PL/SQL is complaining that TRUE is not a valid identifier, or variable. Set up a local variable, set it to TRUE, and pass it into the get_something function.

A slight tangent -- if you want to parse and evaluate an entire expression string which contains (nested!) functions, consider NCalc (http://ncalc.codeplex.com/ and nuget)

Ex. slightly modified from the project documentation:

// the expression to evaluate, e.g. from user input (like a calculator program, hint hint college students)
var exprStr = "10 + MyFunction(3, 6)";
Expression e = new Expression(exprString);

// tell it how to handle your custom function
e.EvaluateFunction += delegate(string name, FunctionArgs args) {
        if (name == "MyFunction")
            args.Result = (int)args.Parameters[0].Evaluate() + (int)args.Parameters[1].Evaluate();
    };

// confirm it worked
Debug.Assert(19 == e.Evaluate());

And within the EvaluateFunction delegate you would call your existing function.

There is no automated uninstaller.

You have to remove Eclipse manually. At least Eclipse does not write anything in the system registry, so deleting some directories and files is enough.

Note: I use Unix style paths in this answer but the locations should be the same on Windows or Unix systems, so ~ refers to the user home directory even on Windows.

Why is there no uninstaller?

According to this discussion about uninstalling Eclipse, the reasoning for not providing an uninstaller is that the Eclipse installer is supposed to just automate a few tasks that in the past had to be done manually (like downloading and extracting Eclipse and adding shortcuts), so they also can be undone manually. There is no entry in "Programs and Features" because the installer does not register anything in the system registry.

How to quickly uninstall Eclipse

Just delete the Eclipse directory and any desktop and start menu shortcuts and be done with it, if you don't mind a few leftover files.

In my opinion this is generally enough and I would stop here, because multiple Eclipse installations can share some files and you don't accidentally want to delete those shared files. You also keep all your projects.

How to completely uninstall Eclipse

If you really want to remove Eclipse without leaving any traces, you have to manually delete

• all desktop and start menu shortcuts
• the installation directory (e.g. ~/eclipse/photon/)
• the p2 bundle pool (which is often shared with other eclipse installations)

The installer has a "Bundle Pools" menu entry which lists the locations of all bundle pools. If you have other Eclipse installations on your system you can use the "Cleanup Agent" to clean up unused bundles. If you don't have any other Eclipse installations you can delete the whole bundle pool directory instead (by default ~/p2/).

If you want to completely remove the Eclipse installer too, delete the installer's executable and the ~/.eclipse/ directory.

Depending on what kind of work you did with Eclipse, there can be more directories that you may want to delete. If you used Maven, then ~/.m2/ contains the Maven cache and settings (shared with Maven CLI and other IDEs). If you develop Eclipse plugins, then there might be JUnit workspaces from test runs, next to you Eclipse workspace. Likewise other build tools and development environments used in Eclipse could have created similar directories.

How to delete all projects

If you want to delete your projects and workspace metadata, you have to delete your workspace(s). The default workspace location is ´~/workspace/´. You can also search for the .metadata directory to get all Eclipse workspaces on your machine.

If you are working with Git projects, these are generally not saved in the workspace but in the ~/git/ directory.

change your

return @str1+'present in the string' ;

to

Have you tried the Generate Scripts (Right click, tasks, generate scripts) option in SQL Management Studio? Does that produce what you mean by a "SQL File"?

As others have said, it will only work when T is constrained to be a reference type. Without any constraints, you can compare with null, but only null - and that comparison will always be false for non-nullable value types.

Instead of calling Equals, it's better to use an IComparer<T> - and if you have no more information, EqualityComparer<T>.Default is a good choice:

public bool Compare<T>(T x, T y)
{
    return EqualityComparer<T>.Default.Equals(x, y);
}

Aside from anything else, this avoids boxing/casting.

Why not using jQuery.parseHTML() http://api.jquery.com/jquery.parsehtml/?

Swift 4.1 and Swift 5. The updatetime method will called after every second and seconds will display on UIlabel.

     var timer: Timer?
     var totalTime = 60
    
     private func startOtpTimer() {
            self.totalTime = 60
            self.timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(updateTimer), userInfo: nil, repeats: true)
        }
    
    @objc func updateTimer() {
            print(self.totalTime)
            self.lblTimer.text = self.timeFormatted(self.totalTime) // will show timer
            if totalTime != 0 {
                totalTime -= 1  // decrease counter timer
            } else {
                if let timer = self.timer { 
                    timer.invalidate()
                    self.timer = nil
                }
            }
        }
    func timeFormatted(_ totalSeconds: Int) -> String {
        let seconds: Int = totalSeconds % 60
        let minutes: Int = (totalSeconds / 60) % 60
        return String(format: "%02d:%02d", minutes, seconds)
    }

Besides its use as a placeholder for unimplemented functions, pass can be useful in filling out an if-else statement ("Explicit is better than implicit.")

def some_silly_transform(n):
    # Even numbers should be divided by 2
    if n % 2 == 0:
        n /= 2
        flag = True
    # Negative odd numbers should return their absolute value
    elif n < 0:
        n = -n
        flag = True
    # Otherwise, number should remain unchanged
    else:
        pass

Of course, in this case, one would probably use return instead of assignment, but in cases where mutation is desired, this works best.

The use of pass here is especially useful to warn future maintainers (including yourself!) not to put redundant steps outside of the conditional statements. In the example above, flag is set in the two specifically mentioned cases, but not in the else-case. Without using pass, a future programmer might move flag = True to outside the condition—thus setting flag in all cases.

Another case is with the boilerplate function often seen at the bottom of a file:

if __name__ == "__main__":
    pass

In some files, it might be nice to leave that there with pass to allow for easier editing later, and to make explicit that nothing is expected to happen when the file is run on its own.

Finally, as mentioned in other answers, it can be useful to do nothing when an exception is caught:

try:
    n[i] = 0
except IndexError:
    pass

I'm not really too clear what you are asking, but using the -f command line option just specifies a file - it doesn't tell make to change directories. If you want to do the work in another directory, you need to cd to the directory:

clean:
    cd gtest-1.4.0 && $(MAKE) clean

Note that each line in Makefile runs in a separate shell, so there is no need to change the directory back.

            nameTranslate.Set(nameTypeNT4, ntUser);
            String userPrincipalName = nameTranslate.Get(nameTypeUserPrincipalName);

            Console.WriteLine(userPrincipalName);

In my case the above suggestions did not work for me. Mine was little different scenario.

When i tried installing bundler using gem install bundler .. But i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

then i tried using sudo gem install bundler then i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
  You don't have write permissions for the /usr/bin directory.

then i tried with sudo gem install bundler -n /usr/local/bin ( Just /usr/bin dint work in my case ).

And then successfully installed bundler

EDIT: I use MacOS, maybe /usr/bin din't work for me for that reason (https://stackoverflow.com/a/34989655/3786657 comment )

I have researched this a little and from what I have found you have four options:

Version 1: Parent div with display as table-cell

If you do not mind using the display:table-cell on your parent div, you can use of the following options:

.area{
    height: 100px;
    width: 100px;
    background: red;
    margin:10px;
    text-align: center;
    display:table-cell;
    vertical-align:middle;
}?

Live DEMO

Version 2: Parent div with display block and content display table-cell

.area{
    height: 100px;
    width: 100px;
    background: red;
    margin:10px;
    text-align: center;
    display:block;
}

.content {
    height: 100px;
    width: 100px;
    display:table-cell;
    vertical-align:middle;    
}?

Live DEMO

Version 3: Parent div floating and content div as display table-cell

.area{
    background: red;
    margin:10px;
    text-align: center;
    display:block;
    float: left;
}

.content {
    display:table-cell;
    vertical-align:middle;
    height: 100px;
    width: 100px;
}?

Live DEMO

Version 4: Parent div position relative with content position absolute

The only problem that I have had with this version is that it seems you will have to create the css for every specific implementation. The reason for this is the content div needs to have the set height that your text will fill and the margin-top will be figured off of that. This issue can be seen in the demo. You can get it to work for every scenario manually by changing the height % of your content div and multiplying it by -.5 to get your margin-top value.

.area{
    position:relative; 
    display:block;
    height:100px;
    width:100px;
    border:1px solid black;
    background:red;
    margin:10px;
}

.content { 
    position:absolute;
    top:50%; 
    height:50%; 
    width:100px;
    margin-top:-25%;
    text-align:center;
}?

The SQL you need is:

Update table set table_column = "test";

The SQL you posted creates a new row rather than updating existing rows.

You could write an extension method (for what it's worth):

public static string EmptyNull(this string str)
{
    return str ?? "";
}

Now this works safely:

string str = null;
string upper = str.EmptyNull().ToUpper();

In my case it is Asp.Net Core 3.1 API. I changed the HTTP GET method from public ActionResult GetValidationRulesForField( GetValidationRulesForFieldDto getValidationRulesForFieldDto) to public ActionResult GetValidationRulesForField([FromQuery] GetValidationRulesForFieldDto getValidationRulesForFieldDto) and its working.

Ok, after some time, here's what I landed on:

.parent {_x000D_
  position: relative;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
}_x000D_
.image1 {_x000D_
  position: relative;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  border: 1px red solid;_x000D_
}_x000D_
.image2 {_x000D_
  position: absolute;_x000D_
  top: 30px;_x000D_
  left: 30px;_x000D_
  border: 1px green solid;_x000D_
}

<div class="parent">_x000D_
  <img class="image1" src="https://placehold.it/50" />_x000D_
  <img class="image2" src="https://placehold.it/100" />_x000D_
</div>

As the simplest solution. That is:

Create a relative div that is placed in the flow of the page; place the base image first as relative so that the div knows how big it should be; place the overlays as absolutes relative to the upper left of the first image. The trick is to get the relatives and absolutes correct.

Using Document Body:

<body ononline="onlineConditions()" onoffline="offlineConditions()">(...)</body>

Using Javascript Event:

window.addEventListener('load', function() {

  function updateOnlineStatus() {

    var condition = navigator.onLine ? "online" : "offline";
    if( condition == 'online' ){
        console.log( 'condition: online')
    }else{
        console.log( 'condition: offline')
    }

  }

  window.addEventListener('online',  updateOnlineStatus );
  window.addEventListener('offline', updateOnlineStatus );

});

Reference:
Document-Body: ononline Event
Javascript-Event: Online and offline events

Additional Thoughts:
To ship around the "network connection is not the same as internet connection" Problem from the above methods: You can check the internet connection once with ajax on the application start and configure an online/offline mode. Create a reconnect button for the user to go online. And add on each failed ajax request a function that kick the user back into the offline mode.

Haskell: difference between . (dot) and $ (dollar sign)

What is the difference between the dot (.) and the dollar sign ($)?. As I understand it, they are both syntactic sugar for not needing to use parentheses.

They are not syntactic sugar for not needing to use parentheses - they are functions, - infixed, thus we may call them operators.

Compose, (.), and when to use it.

(.) is the compose function. So

result = (f . g) x

is the same as building a function that passes the result of its argument passed to g on to f.

h = \x -> f (g x)
result = h x

Use (.) when you don't have the arguments available to pass to the functions you wish to compose.

Right associative apply, ($), and when to use it

($) is a right-associative apply function with low binding precedence. So it merely calculates the things to the right of it first. Thus,

result = f $ g x

is the same as this, procedurally (which matters since Haskell is evaluated lazily, it will begin to evaluate f first):

h = f
g_x = g x
result = h g_x

or more concisely:

result = f (g x)

Use ($) when you have all the variables to evaluate before you apply the preceding function to the result.

We can see this by reading the source for each function.

Read the Source

Here's the source for (.):

-- | Function composition.
{-# INLINE (.) #-}
-- Make sure it has TWO args only on the left, so that it inlines
-- when applied to two functions, even if there is no final argument
(.)    :: (b -> c) -> (a -> b) -> a -> c
(.) f g = \x -> f (g x)

And here's the source for ($):

-- | Application operator.  This operator is redundant, since ordinary
-- application @(f x)@ means the same as @(f '$' x)@. However, '$' has
-- low, right-associative binding precedence, so it sometimes allows
-- parentheses to be omitted; for example:
--
-- >     f $ g $ h x  =  f (g (h x))
--
-- It is also useful in higher-order situations, such as @'map' ('$' 0) xs@,
-- or @'Data.List.zipWith' ('$') fs xs@.
{-# INLINE ($) #-}
($)                     :: (a -> b) -> a -> b
f $ x                   =  f x

Conclusion

Use composition when you do not need to immediately evaluate the function. Maybe you want to pass the function that results from composition to another function.

Use application when you are supplying all arguments for full evaluation.

So for our example, it would be semantically preferable to do

f $ g x

when we have x (or rather, g's arguments), and do:

f . g

when we don't.

For anyone using Ionic 3 and Angular 5, I had the same error pop up and I didn't find any solutions here. But I did find some steps that worked for me.

Steps to reproduce:

• npm install -g cordova ionic
• ionic start myApp tabs
• cd myApp
• cd node_modules/angular/common (no http module exists).

ionic:(run ionic info from a terminal/cmd prompt), check versions and make sure they're up to date. You can also check the angular versions and packages in the package.json folder in your project.

I checked my dependencies and packages and installed cordova. Restarted atom and the error went away. Hope this helps!

This is the closest thing you can get to a "CONST Dictionary":

public static int GetValueByName(string name)
{
    switch (name)
    {
        case "bob": return 1;
        case "billy": return 2;
        default: return -1;
    }
}

The compiler will be smart enough to build the code as clean as possible.

You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"

In ASP.NET Core, use PasswordHasher<TUser>.
 _{• Namespace: Microsoft.AspNetCore.Identity
 • Assembly: Microsoft.Extensions.Identity.Core.dll (NuGet | Source)}

To hash a password, use HashPassword():

var hashedPassword = new PasswordHasher<object?>().HashPassword(null, password);

To verify a password, use VerifyHashedPassword():

var passwordVerificationResult = new PasswordHasher<object?>().VerifyHashedPassword(null, hashedPassword, password);
switch (passwordVerificationResult)
{
    case PasswordVerificationResult.Failed:
        Console.WriteLine("Password incorrect.");
        break;
    
    case PasswordVerificationResult.Success:
        Console.WriteLine("Password ok.");
        break;
    
    case PasswordVerificationResult.SuccessRehashNeeded:
        Console.WriteLine("Password ok but should be rehashed and updated.");
        break;
    
    default:
        throw new ArgumentOutOfRangeException();
}

Pros:

• Part of the .NET platform. Much safer and trustworthier than building your own crypto algorithm.
• Configurable iteration count and future compatibility (see PasswordHasherOptions).
• Took Timing Attack into consideration when verifying password (source), just like what PHP and Go did.

Cons:

• Hashed password format incompatible with those hashed by other libraries or in other languages.

Solution that work for me :

var editorInstance = CKEDITOR.instances[this.editorId];

            editorInstance.on('focus', function(e) {

                console.log("tadaaa");

            });

Technically, Breadth-first search (BFS) by itself does not let you find the shortest path, simply because BFS is not looking for a shortest path: BFS describes a strategy for searching a graph, but it does not say that you must search for anything in particular.

Dijkstra's algorithm adapts BFS to let you find single-source shortest paths.

In order to retrieve the shortest path from the origin to a node, you need to maintain two items for each node in the graph: its current shortest distance, and the preceding node in the shortest path. Initially all distances are set to infinity, and all predecessors are set to empty. In your example, you set A's distance to zero, and then proceed with the BFS. On each step you check if you can improve the distance of a descendant, i.e. the distance from the origin to the predecessor plus the length of the edge that you are exploring is less than the current best distance for the node in question. If you can improve the distance, set the new shortest path, and remember the predecessor through which that path has been acquired. When the BFS queue is empty, pick a node (in your example, it's E) and traverse its predecessors back to the origin. This would give you the shortest path.

If this sounds a bit confusing, wikipedia has a nice pseudocode section on the topic.

A sub class is a small file of a program that extends from some other class. For example you make a class about cars in general and have basic information that holds true for all cars with your constructors and stuff then you have a class that extends from that on a more specific car or line of cars that would have new variables/methods. I see you already have plenty of examples of code from above by the time I get to post this but I hope this description helps.

There are 2 possibilities. In either case PyGame has to be initialized by pygame.init.

import pygame
pygame.init()

Use either the pygame.font module and create a pygame.font.SysFont or pygame.font.Font object. render() a pygame.Surface with the text and blit the Surface to the screen:

my_font = pygame.font.SysFont(None, 50)
text_surface = myfont.render("Hello world!", True, (255, 0, 0))
screen.blit(text_surface, (10, 10))

Or use the pygame.freetype module. Create a pygame.freetype.SysFont() or pygame.freetype.Font object. render() a pygame.Surface with the text or directly render_to() the text to the screen:

my_ft_font = pygame.freetype.SysFont('Times New Roman', 50)
my_ft_font.render_to(screen, (10, 10), "Hello world!", (255, 0, 0))

See also Text and font

Minimal pygame.font example: repl.it/@Rabbid76/PyGame-Text

import pygame

pygame.init()
window = pygame.display.set_mode((500, 150))
clock = pygame.time.Clock()

font = pygame.font.SysFont(None, 100)
text = font.render('Hello World', True, (255, 0, 0))

background = pygame.Surface(window.get_size())
ts, w, h, c1, c2 = 50, *window.get_size(), (128, 128, 128), (64, 64, 64)
tiles = [((x*ts, y*ts, ts, ts), c1 if (x+y) % 2 == 0 else c2) for x in range((w+ts-1)//ts) for y in range((h+ts-1)//ts)]
for rect, color in tiles:
    pygame.draw.rect(background, color, rect)

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.blit(background, (0, 0))
    window.blit(text, text.get_rect(center = window.get_rect().center))
    pygame.display.flip()

pygame.quit()
exit()

Minimal pygame.freetype example: repl.it/@Rabbid76/PyGame-FreeTypeText

import pygame
import pygame.freetype

pygame.init()
window = pygame.display.set_mode((500, 150))
clock = pygame.time.Clock()

ft_font = pygame.freetype.SysFont('Times New Roman', 80)

background = pygame.Surface(window.get_size())
ts, w, h, c1, c2 = 50, *window.get_size(), (128, 128, 128), (64, 64, 64)
tiles = [((x*ts, y*ts, ts, ts), c1 if (x+y) % 2 == 0 else c2) for x in range((w+ts-1)//ts) for y in range((h+ts-1)//ts)]
for rect, color in tiles:
    pygame.draw.rect(background, color, rect)

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.blit(background, (0, 0))
    text_rect = ft_font.get_rect('Hello World')
    text_rect.center = window.get_rect().center
    ft_font.render_to(window, text_rect.topleft, 'Hello World', (255, 0, 0))
    pygame.display.flip()

pygame.quit()
exit()

I would have to agree a foreach would be a lot easier something like

foreach(AllIntegerIDs allIntegerIDs in integerList)
{
Console.WriteLine("{0}\t{1}\t{2}\t{3}\t{4}\n", allIntegerIDs.m_MessageID,
allIntegerIDs.m_MessageType,
allIntegerIDs.m_ClassID,
allIntegerIDs.m_CategoryID,
allIntegerIDs.m_MessageText);
}

Also I would suggest you add properties to access your information instead of public fields, depending on your .net version you can add it like public int MessageType {get; set;} and get rid of the m_ from your public fields, properties etc as it shouldnt be there.

It's a bit ugly but because the NULLs have a special meaning to you, this is the cleanest way I can think to do it:

SELECT recordid, MIN(startdate),
   CASE WHEN MAX(CASE WHEN enddate IS NULL THEN 1 ELSE 0 END) = 0
        THEN MAX(enddate)
   END
FROM tmp GROUP BY recordid

That is, if any row has a NULL, we want to force that to be the answer. Only if no rows contain a NULL should we return the MIN (or MAX).

Made a jsFiddle just for you that solves this issue. simply set $dirty to true, but with a $timeout 0 so it runs after DOM was loaded.

Find it here: JsFiddle

$timeout(function () {
  $scope.form.uName.$dirty = true;
}, 0);

Laravel's Autoload is a bit different:

1) It will in fact use Composer for some stuff

2) It will call Composer with the optimize flag

3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php

4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.

Virtual methods have an implementation and provide the derived classes with the option of overriding it. Abstract methods do not provide an implementation and force the derived classes to override the method.

So, abstract methods have no actual code in them, and subclasses HAVE TO override the method. Virtual methods can have code, which is usually a default implementation of something, and any subclasses CAN override the method using the override modifier and provide a custom implementation.

public abstract class E
{
    public abstract void AbstractMethod(int i);

    public virtual void VirtualMethod(int i)
    {
        // Default implementation which can be overridden by subclasses.
    }
}

public class D : E
{
    public override void AbstractMethod(int i)
    {
        // You HAVE to override this method
    }

Not exactly with HTML5 validation but a little JavaScript can resolve the issue, follow the example below:

<p>Password:</p>
<input name="password" required="required" type="password" id="password" />
<p>Confirm Password:</p>
<input name="password_confirm" required="required" type="password" id="password_confirm" oninput="check(this)" />
<script language='javascript' type='text/javascript'>
    function check(input) {
        if (input.value != document.getElementById('password').value) {
            input.setCustomValidity('Password Must be Matching.');
        } else {
            // input is valid -- reset the error message
            input.setCustomValidity('');
        }
    }
</script>
<br /><br />
<input type="submit" />

Although Pascal's answer was detailed and informative it failed to mention some key information in the assumption that everyone knows how to use phpinfo()

For those that don't:

Navigate to your webservers root folder such as /var/www/

Within this folder create a text file called info.php

Edit the file and type phpinfo()

Navigate to the file such as: http://www.example.com/info.php

Here you will see the php.ini path under Loaded Configuration File:

Make sure you delete info.php when you are done.

If you want Selected.Value being worked you have to do following things:

1. Set DisplayMember
2. Set ValueMember
3. Set DataSource (not use Items.Add, Items.AddRange, DataBinding etc.)

The key point is Set DataSource!

   @{
        List<CategoryModel> CategoryList = CategoryModel.GetCategoryList(UserID);
        IEnumerable<SelectListItem> CategorySelectList = CategoryList.Select(x => new SelectListItem() { Text = x.CategoryName.Trim(), Value = x.CategoryID.Trim() });
    }
    <tr>
        <td>
            <B>Assigned Category:</B>
        </td>
        <td>
            @Html.DropDownList("CategoryList", CategorySelectList, "Select a Category (Optional)")
        </td>
    </tr>

Alternatively, in python 3.6+, you can generate Unicode superscript and copy paste that in your code:

ax1.set_ylabel('Rate (min?¹)')

Rather than Runtime.exec(String command), you need to use the exec(String command, String[] envp, File dir) method signature:

Process p =  Runtime.getRuntime().exec("cmd /c upsert.bat", null, new File("C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert"));

But personally, I'd use ProcessBuilder instead, which is a little more verbose but much easier to use and debug than Runtime.exec().

ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "upsert.bat");
File dir = new File("C:/Program Files/salesforce.com/Data Loader/cliq_process/upsert");
pb.directory(dir);
Process p = pb.start();

It was surprising to see that none of the posts here answered the question. They are either too general, vague, incorrect or do not address the implementation in android.

In MVC, the View layer only knows how to show the user interface (UI). If any data is needed for this, it gets it from the Model layer. But the View does NOT directly ask the model to find the data, it does it through the Controller. So the Controller calls the Model to provide the required data for the View. Once the data is ready, the Controller informs the View that the data is ready to be acquired from the Model. Now the View can get the data from the Model.

This flow can be summarised as below:

It is worth noting that the View can know about the availability of the data in the Model either through Controller -- also known as Passive MVC -- or by observing the data in the Model by registering observables to it, which is Active MVC.

On the implementation part, one of the first things that comes to mind is that what android component should be used for the View? Activity  or Fragment ?

The answer is that it does not matter and both can be used. The View should be able to present the user interface (UI) on the device and respond to the user's interaction with the UI. Both Activity  and Fragment  provide the required methods for this.

In the example app used in this article I have used Activity for the View layer, but Fragment  can also be used.

The complete sample app can be found in the 'mvc' branch of my GitHub repo here.

I have also dealt with the pros and cons of MVC architecture in android through an example here.

For those interested, I have started a series of articles on android app architecture here in which I compare the different architectures, i.e. MVC, MVP, MVVM, for android app development through a complete working app.

this is your html code where you are calling function to convert 24 hour time format to 12 hour with am/pm

<pre id="tests" onClick="tConvert('18:00:00')">_x000D_
  test on click 18:00:00_x000D_
</pre>_x000D_
<span id="rzlt"></span>

now in js code write this tConvert function as it is

 function tConvert (time)_x000D_
  {_x000D_
     _x000D_
   // Check correct time format and split into components_x000D_
   time = time.toString ().match (/^([01]\d|2[0-3])(:)([0-5]\d)(:[0-5]\d)?$/) || [time];_x000D_
_x000D_
    if (time.length > 1) _x000D_
    { // If time format correct_x000D_
        _x000D_
      time = time.slice (1);  // Remove full string match value_x000D_
      time[5] = +time[0] < 12 ? 'AM' : 'PM'; // Set AM/PM_x000D_
      time[0] = +time[0] % 12 || 12; // Adjust hours_x000D_
    }_x000D_
    //return time; // return adjusted time or original string_x000D_
      var tel = document.getElementById ('rzlt');_x000D_
      _x000D_
      tel.innerHTML= time.join ('');_x000D_
  }

converting 18:00:00 to 6:00:00PM working for me

If you just want to have an event when a tab is selected, this is the correct way:

<TabControl>
    <TabItem Selector.Selected="OnTabSelected" />
    <TabItem Selector.Selected="OnTabSelected" />
    <TabItem Selector.Selected="OnTabSelected" />
    <!-- You can also catch the unselected event -->
    <TabItem Selector.Unselected="OnTabUnSelected" />
</TabControl>

And in your code

    private void OnTabSelected(object sender, RoutedEventArgs e)
    {
        var tab = sender as TabItem;
        if (tab != null)
        {
            // this tab is selected!
        }
    }

Try this.

Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.

Use DateTime::diff (aka date_diff):

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);

Or:

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);

You can then get the interval as a integer by calling $interval->days.

Canvases are transparent by default.

Try setting a page background image, and then put a canvas over it. If nothing is drawn on the canvas, you can fully see the page background.

Think of a canvas as like painting on a glass plate.

With small custom synchronization context, sync function can wait for completion of async function, without creating deadlock. Here is small example for WinForms app.

I had the same issue, just opening another terminal with a bash on it worked for me :

create container:

docker run -d mcr.microsoft.com/mssql/server:2019-CTP3.0-ubuntu
containerid=52bbc9b30557

start container:

docker start 52bbc9b30557

start bash to keep container running:

docker exec -it 52bbc9b30557 bash

start process you need:

docker exec -it 52bbc9b30557 /path_to_cool_your_app

Let's not forget our relatively new friend, java-8 stream API. If you need to preprocess list before converting it to a set, it's better to have something like:

list.stream().<here goes some preprocessing>.collect(Collectors.toSet());

I think you are trying to over complicate things. A simple solution is to just style your checkbox by default with the unchecked styles and then add the checked state styles.

input[type="checkbox"] {
  // Unchecked Styles
}
input[type="checkbox"]:checked {
  // Checked Styles
}

I apologize for bringing up an old thread but felt like it could have used a better answer.

EDIT (3/3/2016):

W3C Specs state that :not(:checked) as their example for selecting the unchecked state. However, this is explicitly the unchecked state and will only apply those styles to the unchecked state. This is useful for adding styling that is only needed on the unchecked state and would need removed from the checked state if used on the input[type="checkbox"] selector. See example below for clarification.

input[type="checkbox"] {
  /* Base Styles aka unchecked */
  font-weight: 300; // Will be overwritten by :checked
  font-size: 16px; // Base styling
}
input[type="checkbox"]:not(:checked) {
  /* Explicit Unchecked Styles */
  border: 1px solid #FF0000; // Only apply border to unchecked state
}
input[type="checkbox"]:checked {
  /* Checked Styles */
  font-weight: 900; // Use a bold font when checked
}

Without using :not(:checked) in the example above the :checked selector would have needed to use a border: none; to achieve the same affect.

Use the input[type="checkbox"] for base styling to reduce duplication.

Use the input[type="checkbox"]:not(:checked) for explicit unchecked styles that you do not want to apply to the checked state.

You cat try with below command

cat log|grep -e word1 -e word2

Just wanted to provide a different option for this. In my case, I usually work on my individual branches then merge to master, and the individual commits I do to my local are not that important.

Due to a git hook that checks for the appropriate ticket number on Jira but was case sensitive, I was prevented from pushing my code. Also, the commit was done long ago and I didn't want to count how many commits to go back on the rebase.

So what I did was to create a new branch from latest master and squash all commits from problem branch into a single commit on new branch. It was easier for me and I think it's good idea to have it here as future reference.

From latest master:

git checkout -b new-branch

Then

git merge --squash problem-branch
git commit -m "new message" 

Referece: https://github.com/rotati/wiki/wiki/Git:-Combine-all-messy-commits-into-one-commit-before-merging-to-Master-branch

The data is coming back as the string representation of the JSON and you aren't converting it back to a JavaScript object. Set the dataType to just 'json' to have it converted automatically.

In SQL Server 2016 and above, there is a new feature called Temporal Tables that aims to solve this challenge with minimal effort from developer. The concept of temporal table is similar to Change Data Capture (CDC), with the difference that temporal table has abstracted most of the things that you had to do manually if you were using CDC.

Actually whether there are digits or not is irrelevant. The . (dot) is forbidden if you want to cast to int. Dot can't - logically - be part of Integer definition, so even:

select cast ('7.0' as int)
select cast ('7.' as int)

will fail but both are fine for floats.

Most of the answers dont include the results of ALL promises individually, so in case someone is looking for this particular behaviour, this is a possible solution using recursion.

It follows the style of Promise.all:

• Returns the array of results in the .then() callback.

• If some promise fails, its returned immediately in the .catch() callback.

const promiseEach = (arrayOfTasks) => {_x000D_
  let results = []_x000D_
  return new Promise((resolve, reject) => {_x000D_
    const resolveNext = (arrayOfTasks) => {_x000D_
      // If all tasks are already resolved, return the final array of results_x000D_
      if (arrayOfTasks.length === 0) return resolve(results)_x000D_
_x000D_
      // Extract first promise and solve it_x000D_
      const first = arrayOfTasks.shift()_x000D_
_x000D_
      first().then((res) => {_x000D_
        results.push(res)_x000D_
        resolveNext(arrayOfTasks)_x000D_
      }).catch((err) => {_x000D_
        reject(err)_x000D_
      })_x000D_
    }_x000D_
    resolveNext(arrayOfTasks)_x000D_
  })_x000D_
}_x000D_
_x000D_
// Lets try it _x000D_
_x000D_
const promise = (time, shouldThrowError) => new Promise((resolve, reject) => {_x000D_
  const timeInMs = time * 1000_x000D_
  setTimeout(()=>{_x000D_
    console.log(`Waited ${time} secs`)_x000D_
    if (shouldThrowError) reject(new Error('Promise failed'))_x000D_
    resolve(time)_x000D_
  }, timeInMs)_x000D_
})_x000D_
_x000D_
const tasks = [() => promise(1), () => promise(2)]_x000D_
_x000D_
promiseEach(tasks)_x000D_
  .then((res) => {_x000D_
    console.log(res) // [1, 2]_x000D_
  })_x000D_
  // Oops some promise failed_x000D_
  .catch((error) => {_x000D_
    console.log(error)_x000D_
  })

Note about the tasks array declaration:

In this case is not possible to use the following notation like Promise.all would use:

const tasks = [promise(1), promise(2)]

And we have to use:

const tasks = [() => promise(1), () => promise(2)]

The reason is that JavaScript starts executing the promise immediatelly after its declared. If we use methods like Promise.all, it just checks that the state of all of them is fulfilled or rejected, but doesnt start the exection itself. Using () => promise() we stop the execution until its called.

I was getting this same error, in our case it was caused by a load balancer. We hade to make sure that the persistance was set to Source IP. Otherwise the login form was opened by one server, and processed by the other, which would fail to set the authentication cookie correctly. Maybe this helps someone else

I think I figured out the problem, this input field is part of a reactive form (?), since you have included formControlName. This means that what you are trying to do by disabling the input field with is_edit is not working, e.g your attempt [disabled]="is_edit", which would in other cases work. With your form you need to do something like this:

toggle() {
  let control = this.myForm.get('name')
  control.disabled ? control.enable() : control.disable();
}

and lose the is_edit altogether.

if you want the input field to be disabled as default, you need to set the form control as:

name: [{value: '', disabled:true}]

Here's a plunker

This extension gives you native system blue color.

extension UIColor {

    static var systemBlue: UIColor {
        return UIButton(type: .system).tintColor
    }

}

UPDATE

Please forget what I wrote above, just figured out - there're native extension with predefined system colors we've been looking for, including system blue:

// System colors

extension UIColor {


    /* Some colors that are used by system elements and applications.
     * These return named colors whose values may vary between different contexts and releases.
     * Do not make assumptions about the color spaces or actual colors used.
     */

    ... 

    @available(iOS 7.0, *)
    open class var systemBlue: UIColor { get }
    ... 
}

You can use it directly:

myView.tintColor = .systemBlue

In IE9, it is possible with purely a hack as advised by @Spudley. Since you've customized height and width of the div and select, you need to change div:before css to match yours.

In case if it is IE10 then using below css3 it is possible

select::-ms-expand {
    display: none;
}

However if you're interested in jQuery plugin, try Chosen.js or you can create your own in js.

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

Much easier aproach. Consider a task:

provision:
        ansible-playbook -vvvv \
        -i .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory \
        --private-key=.vagrant/machines/default/virtualbox/private_key \
        --start-at-task="$(AT)" \
        -u vagrant playbook.yml

Now when I want to call it I just run something like:

AT="build assets" make provision

or just:

make provision in this case AT is an empty string

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.

Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.

So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.

Try This

SELECT @PrimaryContactKey = c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey 
    AND i.invckey = @tmp_key

UPDATE tarinvoice SET confirmtocntctkey = @PrimaryContactKey 
WHERE invckey = @tmp_key
FETCH NEXT FROM @get_invckey INTO @tmp_key

You would declare this variable outside of your loop as just a standard TSQL variable.

I should also note that this is how you would do it for any type of select into a variable, not just when dealing with cursors.

Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

For older versions of Hibernate (<5.2):

Assuming the class name is Book:

return (Number) session.createCriteria("Book")
                  .setProjection(Projections.rowCount())
                  .uniqueResult();

It is at least a Number, most likely a Long.

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

I know this might seem to be extremely late.. however it may help someone out there

I wanted to get the AM PM part of the date, so I used what Andy advised:

dateTime.ToString("tt");

I used that part to construct a Path to save my files.. I built my assumptions that I will get either AM or PM and nothing else !!

however when I used a PC that its culture is not English ..( in my case ARABIC) .. my application failed becase the format "tt" returned something new not AM nor PM (? or ?)..

So the fix to this was to ignore the culture by adding the second argument as follow:

dateTime.ToString("tt", CultureInfo.InvariantCulture);

.. of course u have to add : using System.Globalization; on top of ur file I hope that will help someone :)

To the best of my understanding, time.clock() has as much precision as your system will allow it.

Single quotes will not parse PHP variables inside of them. Either use double quotes or use a dot to extend the echo.

$variableName = 'Ralph';
echo 'Hello '.$variableName.'!';

OR

echo "Hello $variableName!";

And in your case:

$i = 1;
echo '<p class="paragraph'.$i.'"></p>';
++i;

OR

$i = 1;
echo "<p class='paragraph$i'></p>";
++i;

I usually put these lines at the beginning of my stored procedure, and then at the end.

It is an "exists" check for #temp tables.

IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
begin
        drop table #MyCoolTempTable
end

Full Example:

CREATE PROCEDURE [dbo].[uspTempTableSuperSafeExample]
AS
BEGIN
    SET NOCOUNT ON;


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    CREATE TABLE #MyCoolTempTable (
        MyCoolTempTableKey INT IDENTITY(1,1),
        MyValue VARCHAR(128)
    )  

    INSERT INTO #MyCoolTempTable (MyValue)
        SELECT LEFT(@@VERSION, 128)
        UNION ALL SELECT TOP 10 LEFT(name, 128) from sysobjects

    SELECT MyCoolTempTableKey, MyValue FROM #MyCoolTempTable


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    SET NOCOUNT OFF;
END

When a log scale is used the number of major ticks can be fixed with the following command

import matplotlib.pyplot as plt

....

plt.locator_params(numticks=12)
plt.show()

The value set to numticks determines the number of axis ticks to be displayed.

Credits to @bgamari's post for introducing the locator_params() function, but the nticks parameter throws an error when a log scale is used.

https://angular.io/guide/user-input - there's a simple example .

As per your code

<$php
     $val = $myService->getValue(); // Makes an API and database call
     echo '<span id="value">'.$val.'</span>';
$>

Now you can get value using DOM, use innerHTML of span id, in this case you don't need to do any call to server, or Ajax or another thing.

Your page will print it using PHP, and you JavaScript will get value using DOM.

result = bytes.fromhex(some_hex_string)

open command prompt and run the following commands (assuming python 2.7):

cd c:\Python27\scripts\
pip install opencv-python

the above works for me for python 2.7 on windows 10 64 bit

If you don't want to modify the manifest file, you can manually store the context in a static variable in your initial activity:

public class App {
    private static Context context;

    public static void setContext(Context cntxt) {
        context = cntxt;
    }

    public static Context getContext() {
        return context;
    }
}

And just set the context when your activity (or activities) start:

// MainActivity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Set Context
    App.setContext(getApplicationContext());

    // Other stuff
}

Note: Like all other answers, this is a potential memory leak.

Here's a great method I recently found on a different stack overflow post regarding multi-dimensional arrays, but the answer works beautifully for single dimensional arrays as well:

# Create an 8 x 5 matrix of 0's:
w, h = 8, 5;
MyMatrix = [ [0 for x in range( w )] for y in range( h ) ]  

# Create an array of objects:
MyList = [ {} for x in range( n ) ]

I love this because you can specify the contents and size dynamically, in one line!

One more for the road:

# Dynamic content initialization:
MyFunkyArray = [ x * a + b for x in range ( n ) ]

The term "clone" is ambiguous (though the Java class library includes a Cloneable interface) and can refer to a deep copy or a shallow copy. Deep/shallow copies are not specifically tied to Java but are a general concept relating to making a copy of an object, and refers to how members of an object are also copied.

As an example, let's say you have a person class:

class Person {
    String name;
    List<String> emailAddresses
}

How do you clone objects of this class? If you are performing a shallow copy, you might copy name and put a reference to emailAddresses in the new object. But if you modified the contents of the emailAddresses list, you would be modifying the list in both copies (since that's how object references work).

A deep copy would mean that you recursively copy every member, so you would need to create a new List for the new Person, and then copy the contents from the old to the new object.

Although the above example is trivial, the differences between deep and shallow copies are significant and have a major impact on any application, especially if you are trying to devise a generic clone method in advance, without knowing how someone might use it later. There are times when you need deep or shallow semantics, or some hybrid where you deep copy some members but not others.

The easiest way to do this would be to use a filter.

You can either filter for any cells in column A that don't have a "-" and copy / paste, or (my more preferred method) filter for all cells that do have a "-" and then select all and delete - Once you remove the filter, you're left with what you need.

Hope this helps.

You can do:

t1<- t1[-4:-6,-7:-9]

This did NOT work in IE8 (yet did in FF):

$("#selectList").append(new Option("option text", "value"));

This DID work:

var o = new Option("option text", "value");
/// jquerify the DOM object 'o' so we can use the html method
$(o).html("option text");
$("#selectList").append(o);

Note that you can also create your own structures using a Map.Entry as the main type, using its basic implementation AbstractMap.SimpleEntry. For instance, if you wanted to have an ordered list of entries, you could write:

List<Map.Entry<String, Integer>> entries = new ArrayList<>();
entries.add(new AbstractMap.SimpleEntry<String, Integer>(myStringValue, myIntValue));

And so on. From there, you have a list of tuples. Very useful when you want ordered tuples and a basic Map is a no-go.

I've used this in the past and it doesn't require a full table scan to see if something exists. It's super fast...

UPDATE TableName SET column=value WHERE column=value
IF @@ROWCOUNT=0
BEGIN
     --Do work
END             

Simplest way I found:

cd my_dir && tar -czvf ../my_dir.tar.gz *

Quote from The Swift Programming Language, which answers your question:

“Swift’s compiler performs four helpful safety-checks to make sure that two-phase initialization is completed without error:”

Safety check 1 “A designated initializer must ensure that all of the “properties introduced by its class are initialized before it delegates up to a superclass initializer.”

Use gettimeofday() to get the time in seconds and microseconds. Combining and rounding to milliseconds is left as an exercise.

I think your code should work just remove one thing from here but it'll do redirection from current page within existing window

<asp:Button ID="btn" runat="Server" Text="SUBMIT" 

 OnClick="btnNewEntry_Click"/>    



protected void btnNewEntry_Click(object sender, EventArgs e)
 {
    Response.Redirect("CMS_1.aspx");
 }

And if u wanna do the this via client side scripting Use this way

<asp:Button ID="BTN" runat="server" Text="Submit" OnClientClick="window.open('Default2.aspx')" />

According to me you should prefer the Client Side Scripting because just to open a new window server side will take a post back and that will be useless..

In VS2015, this worked to turn the Enter key into <br>

myCKEControl.EnterMode = CKEditor.NET.EnterMode.BR

Personally, I don't care if my resulting text only has <br> and not <p>. It renders perfectly fine and it looks the way I want it to. In the end, it works.

The general methodology would be to iterate through the ArrayList, and insert the values into the HashMap. An example is as follows:

HashMap<String, Product> productMap = new HashMap<String, Product>();
for (Product product : productList) {
   productMap.put(product.getProductCode(), product);
}

Its complete installation nightmare, but I'll give one more hope you can avoid building opencv from source:

pip install opencv-contrib-python

Balanced tree is a tree whose height is of order of log(number of elements in the tree).

height = O(log(n))
O, as in asymptotic notation i.e. height should have same or lower asymptotic
growth rate than log(n)
n: number of elements in the tree

The definition given "a tree is balanced of each sub-tree is balanced and the height of the two sub-trees differ by at most one" is followed by AVL trees.

Since, AVL trees are balanced but not all balanced trees are AVL trees, balanced trees don't hold this definition and internal nodes can be unbalanced in them. However, AVL trees require all internal nodes to be balanced.

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

width: 100%

I had to add the CSS class into the asp:DropDownList element

This is what you need!

function onGeneratedRow(columnsResult)
{
    var jsonData = {};
    columnsResult.forEach(function(column) 
    {
        var columnName = column.metadata.colName;
        jsonData[columnName] = column.value;
    });
    viewData.employees.push(jsonData);
 }

If you're using Django installed you can also try filesizeformat:

from django.template.defaultfilters import filesizeformat
filesizeformat(1073741824)

=>

"1.0 GB"

My problem was with Google Chrome cache. I tested this by running my web application on Firefox and I didn't got that error there. So then I decided trying emptying cache of Google Chrome and it worked.

Note that this isn't perfect, since if you had something like, say, <a title=">"> it would break. However, it's about the closest you'd get in non-library Python without a really complex function:

import re

TAG_RE = re.compile(r'<[^>]+>')

def remove_tags(text):
    return TAG_RE.sub('', text)

However, as lvc mentions xml.etree is available in the Python Standard Library, so you could probably just adapt it to serve like your existing lxml version:

def remove_tags(text):
    return ''.join(xml.etree.ElementTree.fromstring(text).itertext())

Use the command as

java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>

The above command will set the mentioned paths to classpath only once for executing the class named TestClass.

If you want to execute more then one classes, then you can follow this

set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"

After this you can execute as many classes as you want just by simply typing

java <your-class-name>

The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)

If you want to set the classpth only once so that it could work for everytime, then do as follows

1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
    a.  Variable Name-     classpath
    b.  Variable Value-    .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.

Remember this will work every time. You don't need to explicitly set the classpath again and again.

NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.

Hope this will help you.

You should do it in componentDidMount and refs callback instead. Something like this

componentDidMount(){
   this.nameInput.focus(); 
}

class App extends React.Component{_x000D_
  componentDidMount(){_x000D_
    this.nameInput.focus();_x000D_
  }_x000D_
  render() {_x000D_
    return(_x000D_
      <div>_x000D_
        <input _x000D_
          defaultValue="Won't focus" _x000D_
        />_x000D_
        <input _x000D_
          ref={(input) => { this.nameInput = input; }} _x000D_
          defaultValue="will focus"_x000D_
        />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
    _x000D_
ReactDOM.render(<App />, document.getElementById('app'));

Add up to Dmitry's answer, if you don't want to handle unique key IDs manually, you can use React.Children.toArray as proposed in the React documentation

React.Children.toArray

Returns the children opaque data structure as a flat array with keys assigned to each child. Useful if you want to manipulate collections of children in your render methods, especially if you want to reorder or slice this.props.children before passing it down.

Note:

React.Children.toArray() changes keys to preserve the semantics of nested arrays when flattening lists of children. That is, toArray prefixes each key in the returned array so that each element’s key is scoped to the input array containing it.

 <div>
    <ul>
      {
        React.Children.toArray(
          this.state.data.map((item, i) => <li>Test</li>)
        )
      }
    </ul>
  </div>

If you need extract the text without the brackets, you can use bash awk

echo " [hola mundo] " | awk -F'[][]' '{print $2}'

result:

hola mundo

without site name

{{Storage::url($photoLink)}}

if you want to add site name to it example to append on api JSON felids

 public function getPhotoFullLinkAttribute()
{
    return env('APP_URL', false).Storage::url($this->attributes['avatar']) ;
}

the mySql blob class has the following function :

blob.getBytes

use it like this:

//(assuming you have a ResultSet named RS)
Blob blob = rs.getBlob("SomeDatabaseField");

int blobLength = (int) blob.length();  
byte[] blobAsBytes = blob.getBytes(1, blobLength);

//release the blob and free up memory. (since JDBC 4.0)
blob.free();

you can use long or double.

You should consider replacing your line breaks with <br/>. In HTML a line break will only stand for new line in your code.

Alternatively you can use some other HTML markups like placing your lines in paragraphs:

<p>Sample line</p>
<p>Another line</p>

or other wrappers like for instance <div>sample</div> with CSS attribute: display: block.

You can also use <pre>. The content of pre will have its HTML styling ignored. In other words it will display pure HTML with normal \n line breaks.

There seems to be many causes for this issue. Recently, I added an activity to test with called NewActivity. This created a file called res/menu/new.xml and gradle did not like that name because new is a reserved word.

gradlew clean

or

"Tools" -> "Android" -> "Sync Project with Gradle Files"

Those are definitely good things to try, but you may have some other issues you need to resolve before you run those commands.

Well, to give some perspective, let me compare node.js with apache.

Apache is a multi-threaded HTTP server, for each and every request that the server receives, it creates a separate thread which handles that request.

Node.js on the other hand is event driven, handling all requests asynchronously from single thread.

When A and B are received on apache, two threads are created which handle requests. Each handling the query separately, each waiting for the query results before serving the page. The page is only served until the query is finished. The query fetch is blocking because the server cannot execute the rest of thread until it receives the result.

In node, c.query is handled asynchronously, which means while c.query fetches the results for A, it jumps to handle c.query for B, and when the results arrive for A arrive it sends back the results to callback which sends the response. Node.js knows to execute callback when fetch finishes.

In my opinion, because it's a single thread model, there is no way to switch from one request to another.

Actually the node server does exactly that for you all the time. To make switches, (the asynchronous behavior) most functions that you would use will have callbacks.

Edit

The SQL query is taken from mysql library. It implements callback style as well as event emitter to queue SQL requests. It does not execute them asynchronously, that is done by the internal libuv threads that provide the abstraction of non-blocking I/O. The following steps happen for making a query :

1. Open a connection to db, connection itself can be made asynchronously.
2. Once db is connected, query is passed on to the server. Queries can be queued.
3. The main event loop gets notified of the completion with callback or event.
4. Main loop executes your callback/eventhandler.

The incoming requests to http server are handled in the similar fashion. The internal thread architecture is something like this:

The C++ threads are the libuv ones which do the asynchronous I/O (disk or network). The main event loop continues to execute after the dispatching the request to thread pool. It can accept more requests as it does not wait or sleep. SQL queries/HTTP requests/file system reads all happen this way.

It means something like this:

std::vector<Movie *> movies;

Then you add to the vector as you read lines:

movies.push_back(new Movie(...));

Remember to delete all of the Movie* objects once you are done with the vector.

You could have the active class be dependent upon a boolean data value:

<th 
  class="initial " 
  v-on="click: myFilter"
  v-class="{active: isActive}">
  <span class="wkday">M</span>
</th>

new Vue({
  el: '#my-container',

  data: {
    isActive: false
  },

  methods: {
    myFilter: function() {
      this.isActive = !this.isActive;
      // some code to filter users
    }
  }
})

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

3. both method work with all browser but when it's automatically work what you want type a code for it? so i think method 1 is better.

For me the simple solution works to set cookies in HttpRequestMessage object.

protected async Task<HttpResponseMessage> SendRequest(HttpRequestMessage requestMessage, CancellationToken cancellationToken = default(CancellationToken))
{
    requestMessage.Headers.Add("Cookie", $"<Cookie Name 1>=<Cookie Value 1>;<Cookie Name 2>=<Cookie Value 2>");

    return await _httpClient.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false);
}

Step 1 :

Create ts : app/_helpers/must-match.validator.ts

import { FormGroup } from '@angular/forms';

export function MustMatch(controlName: string, matchingControlName: string) {
    return (formGroup: FormGroup) => {
        const control = formGroup.controls[controlName];
        const matchingControl = formGroup.controls[matchingControlName];

        if (matchingControl.errors && !matchingControl.errors.mustMatch) { 
            return;
        } 
        if (control.value !== matchingControl.value) {
            matchingControl.setErrors({ mustMatch: true });
        } else {
            matchingControl.setErrors(null);
        }
    }
}

Step 2 :

Use in your component.ts

import { MustMatch } from '../_helpers/must-match.validator'; 

ngOnInit() {
    this.loginForm = this.formbuilder.group({
      Password: ['', [Validators.required, Validators.minLength(6)]], 
      ConfirmPassword: ['', [Validators.required]],
    }, {
      validator: MustMatch('Password', 'ConfirmPassword')
    });
  } 

Step 3 :

Use In View/Html

<input type="password" formControlName="Password" class="form-control" autofocus>
                <div *ngIf="loginForm.controls['Password'].invalid && (loginForm.controls['Password'].dirty || loginForm.controls['Password'].touched)" class="alert alert-danger">
                    <div *ngIf="loginForm.controls['Password'].errors.required">Password Required. </div> 
                    <div *ngIf="loginForm.controls['Password'].errors.minlength">Password must be at least 6 characters</div>
                </div> 


 <input type="password" formControlName="ConfirmPassword" class="form-control" >
                <div *ngIf="loginForm.controls['ConfirmPassword'].invalid && (loginForm.controls['ConfirmPassword'].dirty || loginForm.controls['ConfirmPassword'].touched)" class="alert alert-danger">
                    <div *ngIf="loginForm.controls['ConfirmPassword'].errors.required">ConfirmPassword Required. </div> 
                    <div *ngIf="loginForm.controls['ConfirmPassword'].errors.mustMatch">Your password and confirmation password do not match.</div>
                </div> 

To expand Konamiman's solution (including all relevant null checks), this is what I've been doing:

if (node.Attributes != null)
{
   var nameAttribute = node.Attributes["Name"];
   if (nameAttribute != null) 
      return nameAttribute.Value;

   throw new InvalidOperationException("Node 'Name' not found.");
}

Some OS-specific interfaces:

• Mac OS X: _NSGetExecutablePath() (man 3 dyld)
• Linux: readlink /proc/self/exe
• Solaris: getexecname()
• FreeBSD: sysctl CTL_KERN KERN_PROC KERN_PROC_PATHNAME -1
• FreeBSD if it has procfs: readlink /proc/curproc/file (FreeBSD doesn't have procfs by default)
• NetBSD: readlink /proc/curproc/exe
• DragonFly BSD: readlink /proc/curproc/file
• Windows: GetModuleFileName() with hModule = NULL

There are also third party libraries that can be used to get this information, such as whereami as mentioned in prideout's answer, or if you are using Qt, QCoreApplication::applicationFilePath() as mentioned in the comments.

The portable (but less reliable) method is to use argv[0]. Although it could be set to anything by the calling program, by convention it is set to either a path name of the executable or a name that was found using $PATH.

Some shells, including bash and ksh, set the environment variable "_" to the full path of the executable before it is executed. In that case you can use getenv("_") to get it. However this is unreliable because not all shells do this, and it could be set to anything or be left over from a parent process which did not change it before executing your program.

This work on my side.

ResourceBean resourceBean = initResourceBean();
ResponseEntity<ResourceBean> responseEntity  
    = new ResponseEntity<ResourceBean>(resourceBean, HttpStatus.ACCEPTED);
when(restTemplate.exchange(
    Matchers.anyObject(), 
    Matchers.any(HttpMethod.class),
    Matchers.<HttpEntity> any(), 
    Matchers.<Class<ResourceBean>> any())
 ).thenReturn(responseEntity);

Like this:

int counts[26];
memset(counts, 0, sizeof(counts));
char *p = string;
while (*p) {
    counts[tolower(*p++) - 'a']++;
}

This code assumes that the string is null-terminated, and that it contains only characters a through z or A through Z, inclusive.

To understand how this works, recall that after conversion tolower each letter has a code between a and z, and that the codes are consecutive. As the result, tolower(*p) - 'a' evaluates to a number from 0 to 25, inclusive, representing the letter's sequential number in the alphabet.

This code combines ++ and *p to shorten the program.

It's different in every browser.

Some years ago, what you tried, was right. But nowadays it is regarded as a security risk by browser vendors that one cannot see the browsers address bar (for phishing reasons) and so they (or most of them) made the decision to always show the browser address bar. Which is good in my eyes.

I have an idea to use value of id() in logging.
It's cheap to get and it's quite short.
In my case I use tornado and id() would like to have an anchor to group messages scattered and mixed over file by web socket.

Being aware of the transaction (autocommit, explicit and implicit) handling for your database can save you from having to restore data from a backup.

Transactions control data manipulation statement(s) to ensure they are atomic. Being "atomic" means the transaction either occurs, or it does not. The only way to signal the completion of the transaction to database is by using either a COMMIT or ROLLBACK statement (per ANSI-92, which sadly did not include syntax for creating/beginning a transaction so it is vendor specific). COMMIT applies the changes (if any) made within the transaction. ROLLBACK disregards whatever actions took place within the transaction - highly desirable when an UPDATE/DELETE statement does something unintended.

Typically individual DML (Insert, Update, Delete) statements are performed in an autocommit transaction - they are committed as soon as the statement successfully completes. Which means there's no opportunity to roll back the database to the state prior to the statement having been run in cases like yours. When something goes wrong, the only restoration option available is to reconstruct the data from a backup (providing one exists). In MySQL, autocommit is on by default for InnoDB - MyISAM doesn't support transactions. It can be disabled by using:

SET autocommit = 0

An explicit transaction is when statement(s) are wrapped within an explicitly defined transaction code block - for MySQL, that's START TRANSACTION. It also requires an explicitly made COMMIT or ROLLBACK statement at the end of the transaction. Nested transactions is beyond the scope of this topic.

Implicit transactions are slightly different from explicit ones. Implicit transactions do not require explicity defining a transaction. However, like explicit transactions they require a COMMIT or ROLLBACK statement to be supplied.

Conclusion

Explicit transactions are the most ideal solution - they require a statement, COMMIT or ROLLBACK, to finalize the transaction, and what is happening is clearly stated for others to read should there be a need. Implicit transactions are OK if working with the database interactively, but COMMIT statements should only be specified once results have been tested & thoroughly determined to be valid.

That means you should use:

SET autocommit = 0;

START TRANSACTION;
  UPDATE ...;

...and only use COMMIT; when the results are correct.

That said, UPDATE and DELETE statements typically only return the number of rows affected, not specific details. Convert such statements into SELECT statements & review the results to ensure correctness prior to attempting the UPDATE/DELETE statement.

Addendum

DDL (Data Definition Language) statements are automatically committed - they do not require a COMMIT statement. IE: Table, index, stored procedure, database, and view creation or alteration statements.

Using SpringApplication.run(Class<?> primarySource, String... arg) worked for me. E.g.:

@SpringBootApplication
public class YourApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(YourApplication.class, args);

    }
}

It's an extension for the User Controls you have in your project.

A user control is a kind of composite control that works much like an ASP.NET Web page—you can add existing Web server controls and markup to a user control, and define properties and methods for the control. You can then embed them in ASP.NET Web pages, where they act as a unit.

Simply, if you want to have some functionality that will be used on many pages in your project then you should create a User control or Composite control and use it in your pages. It just helps you to keep the same functionality and code in one place. And it makes it reusable.

You're getting that error because the default value current_time is not valid for the type DATETIME. That's what it says, and that's whats going on.

The only field you can use current_time on is a timestamp.

There's also php2xmi. You have to do a bit of manual work, but it generates all the classes, so all you have to do is to drag them into a classdiagram in Umbrello.

Otherwise, generating a diagram with the use of reflection and graphviz, is fairly simple. I have a snippet over here, that you can use as a starting point.

Python's standard library has json and urllib2 modules.

This helped me get to my answer. There are two php.ini files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin folder. When connecting to SQL through sqlsrv_connect function, we are referring to the php.ini file in the apache folder. Add the following (as per your version) to this file:

Instead of using a regular expression, just check if string.length > 25

You can consider shapely:

from shapely.geometry import Point
from shapely.geometry.polygon import Polygon

point = Point(0.5, 0.5)
polygon = Polygon([(0, 0), (0, 1), (1, 1), (1, 0)])
print(polygon.contains(point))

From the methods you've mentioned I've only used the second, path.contains_points, and it works fine. In any case depending on the precision you need for your test I would suggest creating a numpy bool grid with all nodes inside the polygon to be True (False if not). If you are going to make a test for a lot of points this might be faster (although notice this relies you are making a test within a "pixel" tolerance):

from matplotlib import path
import matplotlib.pyplot as plt
import numpy as np

first = -3
size  = (3-first)/100
xv,yv = np.meshgrid(np.linspace(-3,3,100),np.linspace(-3,3,100))
p = path.Path([(0,0), (0, 1), (1, 1), (1, 0)])  # square with legs length 1 and bottom left corner at the origin
flags = p.contains_points(np.hstack((xv.flatten()[:,np.newaxis],yv.flatten()[:,np.newaxis])))
grid = np.zeros((101,101),dtype='bool')
grid[((xv.flatten()-first)/size).astype('int'),((yv.flatten()-first)/size).astype('int')] = flags

xi,yi = np.random.randint(-300,300,100)/100,np.random.randint(-300,300,100)/100
vflag = grid[((xi-first)/size).astype('int'),((yi-first)/size).astype('int')]
plt.imshow(grid.T,origin='lower',interpolation='nearest',cmap='binary')
plt.scatter(((xi-first)/size).astype('int'),((yi-first)/size).astype('int'),c=vflag,cmap='Greens',s=90)
plt.show()

, the results is this:

Each argument passed via command line can be accessed with: Wscript.Arguments.Item(0) Where the zero is the argument number: ie, 0, 1, 2, 3 etc.

So in your code you could have:

strFolder = Wscript.Arguments.Item(0) 

Set FSO = CreateObject("Scripting.FileSystemObject")
Set File = FSO.OpenTextFile(strFolder, 2, True)
File.Write "testing"
File.Close
Set File = Nothing
Set FSO = Nothing
Set workFolder = Nothing

Using wscript.arguments.count, you can error trap in case someone doesn't enter the proper value, etc.

Recommendation from JAVA is to assign to null

From https://docs.oracle.com/cd/E19159-01/819-3681/abebi/index.html

Explicitly assigning a null value to variables that are no longer needed helps the garbage collector to identify the parts of memory that can be safely reclaimed. Although Java provides memory management, it does not prevent memory leaks or using excessive amounts of memory.

An application may induce memory leaks by not releasing object references. Doing so prevents the Java garbage collector from reclaiming those objects, and results in increasing amounts of memory being used. Explicitly nullifying references to variables after their use allows the garbage collector to reclaim memory.

One way to detect memory leaks is to employ profiling tools and take memory snapshots after each transaction. A leak-free application in steady state will show a steady active heap memory after garbage collections.

.MERGE_MSG.swp is open in your git, you just need to delete this .swp file. In my case I used following command and it worked fine.

rm .MERGE_MSG.swp

In dplyr you may use n_distinct to "count the number of unique values":

library(dplyr)
myvec %>%
  group_by(name) %>%
  summarise(n_distinct(order_no))

savefig has its own parameter for facecolor. I think an even easier way than the accepted answer is to set them globally just once, instead of putting facecolor=fig.get_facecolor() every time:

plt.rcParams['axes.facecolor']='red'
plt.rcParams['savefig.facecolor']='red'

If you are using Android Lollipop i.e. SDK 21, then:

CookieManager.getInstance().setAcceptCookie(true);

won't work. You need to use:

CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

I ran into same issue and the above line worked as a charm.

Really fast, really easy:

srand(time(NULL)); // Seed the time
int finalNum = rand()%(max-min+1)+min; // Generate the number, assign to variable.

And that is it. However, this is biased towards the lower end, but if you are using C++ TR1/C++11 you can do it using the random header to avoid that bias like so:

#include <random>

std::mt19937 rng(seed);
std::uniform_int_distribution<int> gen(min, max); // uniform, unbiased

int r = gen(rng);

But you can also remove the bias in normal C++ like this:

int rangeRandomAlg2 (int min, int max){
    int n = max - min + 1;
    int remainder = RAND_MAX % n;
    int x;
    do{
        x = rand();
    }while (x >= RAND_MAX - remainder);
    return min + x % n;
}

and that was gotten from this post.

Or, if none of the above works then you can use following approach as it worked for me.

Imagine this is your button

<button class="btn" onclick="NavigateToPdf(${Id});"></button>

I got the value for ${Id} filled using jquery templates. You can use whatever suits your requirement. In the following function, I am setting window.location.href equal to controller name then action name and then finally parameter. I am able to successfully navigate.

function NavigateToPdf(id) {
    window.location.href = "Link/Pdf/" + id;
}

I hope it helps.

If you are using impdp command example from @sathyajith-bhat response:

impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

you will need to use mandatory parameter directory and create and grant it as:

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

or use one of defined:

select * from DBA_DIRECTORIES;

My ORACLE Express 11g R2 has default named DATA_PUMP_DIR (located at {inst_dir}\app\oracle/admin/xe/dpdump/) you sill need to grant it for your user.

In Ubuntu 16.04 default PHP version is 7.0, if you want to use different version then you need to install PHP package according to PHP version:

• PHP 7.2: sudo apt-get install php7.2-curl
• PHP 7.1: sudo apt-get install php7.1-curl
• PHP 7.0: sudo apt-get install php7.0-curl
• PHP 5.6: sudo apt-get install php5.6-curl

Cat class inherits structure from Animal, Carnivore and Pet to also exhibit Polymorphic behaviorism of a domestic pet.

While the solution of moving the contact_email to parameters.yml is easy, as proposed in other answers, that can easily clutter your parameters file if you deal with many bundles or if you deal with nested blocks of configuration.

• First, I'll answer strictly the question.
• Later, I'll give an approach for getting those configs from services without ever passing via a common space as parameters.

FIRST APPROACH: Separated config block, getting it as a parameter

With an extension (more on extensions here) you can keep this easily "separated" into different blocks in the config.yml and then inject that as a parameter gettable from the controller.

Inside your Extension class inside the DependencyInjection directory write this:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        // The next 2 lines are pretty common to all Extension templates.
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // This is the KEY TO YOUR ANSWER
        $container->setParameter( 'my_nice_project.contact_email', $processedConfig[ 'contact_email' ] );

        // Other stuff like loading services.yml
    }

Then in your config.yml, config_dev.yml and so you can set

my_nice_project:
    contact_email: [email protected]

To be able to process that config.yml inside your MyNiceBundleExtension you'll also need a Configuration class in the same namespace:

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root( 'my_nice_project' );

        $rootNode->children()->scalarNode( 'contact_email' )->end();

        return $treeBuilder;
    }
}

Then you can get the config from your controller, as you desired in your original question, but keeping the parameters.yml clean, and setting it in the config.yml in separated sections:

$recipient = $this->container->getParameter( 'my_nice_project.contact_email' );

SECOND APPROACH: Separated config block, injecting the config into a service

For readers looking for something similar but for getting the config from a service, there is even a nicer way that never clutters the "paramaters" common space and does even not need the container to be passed to the service (passing the whole container is practice to avoid).

This trick above still "injects" into the parameters space your config.

Nevertheless, after loading your definition of the service, you could add a method-call like for example setConfig() that injects that block only to the service.

For example, in the Extension class:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // Do not add a paramater now, just continue reading the services.
        $loader = new YamlFileLoader( $container, new FileLocator( __DIR__ . '/../Resources/config' ) );
        $loader->load( 'services.yml' );

        // Once the services definition are read, get your service and add a method call to setConfig()
        $sillyServiceDefintion = $container->getDefinition( 'my.niceproject.sillymanager' );
        $sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'contact_email' ] ) );
    }
}

Then in your services.yml you define your service as usual, without any absolute change:

services:
    my.niceproject.sillymanager:
        class: My\NiceProjectBundle\Model\SillyManager
        arguments: []

And then in your SillyManager class, just add the method:

class SillyManager
{
    private $contact_email;

    public function setConfig( $newConfigContactEmail )
    {
        $this->contact_email = $newConfigContactEmail;
    }
}

Note that this also works for arrays instead of scalar values! Imagine that you configure a rabbit queue and need host, user and password:

my_nice_project:
    amqp:
        host: 192.168.33.55
        user: guest
        password: guest

Of course you need to change your Tree, but then you can do:

$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'amqp' ] ) );

and then in the service do:

class SillyManager
{
    private $host;
    private $user;
    private $password;

    public function setConfig( $config )
    {
        $this->host = $config[ 'host' ];
        $this->user = $config[ 'user' ];
        $this->password = $config[ 'password' ];
    }
}

Hope this helps!

For MYSQL

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

you can use the following code

         Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                pic = new File(Environment.getExternalStorageDirectory(),
                        mApp.getPreference().getString(Common.u_id, "") + ".jpg");

                picUri = Uri.fromFile(pic);

                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, picUri);

                cameraIntent.putExtra("return-data", true);
                startActivityForResult(cameraIntent, PHOTO);

This will try the subdir if the file doesn't exist in the root. Needed this as I moved a basic .html website that expects to be ran at the root level and pushed it to a subdir. Only works if all files are flat (no .htaccess trickery in the subdir possible). Useful for linked things like css and js files.

# Internal Redirect to subdir if file is found there.
RewriteEngine on
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI} !-s
RewriteCond %{DOCUMENT_ROOT}/subdir/%{REQUEST_URI} -s
RewriteRule ^(.*)$ /subdir/$1 [L]

You can add the directories for your build process like:

    ...
   <resources>
     <resource>
       <directory>src/bootstrap</directory>
     </resource>
   </resources>
   ...

The src/main/java is the default path which is not needed to be mentioned in the pom.xml

Just came across this and I've implemented Nathan's solution:

add the line (changing the values as required):

export JAVA_OPTS="-Xms512M -Xmx1024M"

to /usr/share/tomcat7/bin/setenv.sh

If that file doesn't exists then create it and

chown root:root it
chmod 755 it

And then restart tomcat and check it with

ps aux | grep logging

Which should just pick up the instance and show the java parms

I've had a few cranberry-vodkas tonight so I might be missing something...Is setting the range necessary? Why not use:

Activeworkbook.Sheets("Game").Range("A1").value = "Subtotal"

Does this fail as well?

Looks like you tried something similar:

'Worksheets("Game").Range("A1") = "Asdf"

However, Worksheets is a collection, so you can't reference "Game". I think you need to use the Sheets object instead.

There are a couple of improvements to be made on the existing answers.

Firstly the UIKeyboardWillChangeFrameNotification is probably the best notification as it handles changes that aren't just show/hide but changes due to keyboard changes (language, using 3rd party keyboards etc.) and rotations too (but note comment below indicating the keyboard will hide should also be handled to support hardware keyboard connection).

Secondly the animation parameters can be pulled from the notification to ensure that animations are properly together.

There are probably options to clean up this code a bit more especially if you are comfortable with force unwrapping the dictionary code.

 class MyViewController: UIViewController {

   // This constraint ties an element at zero points from the bottom layout guide
   @IBOutlet var keyboardHeightLayoutConstraint: NSLayoutConstraint?
 
   override func viewDidLoad() {
     super.viewDidLoad()
     NotificationCenter.default.addObserver(self,
       selector: #selector(self.keyboardNotification(notification:)),
       name: UIResponder.keyboardWillChangeFrameNotification,
       object: nil)
   }
 
   deinit {
     NotificationCenter.default.removeObserver(self)
   }
 
   @objc func keyboardNotification(notification: NSNotification) {
     guard let userInfo = notification.userInfo else { return }

     let endFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue
     let endFrameY = endFrame?.origin.y ?? 0
     let duration:TimeInterval = (userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? NSNumber)?.doubleValue ?? 0
     let animationCurveRawNSN = userInfo[UIResponder.keyboardAnimationCurveUserInfoKey] as? NSNumber
     let animationCurveRaw = animationCurveRawNSN?.uintValue ?? UIView.AnimationOptions.curveEaseInOut.rawValue
     let animationCurve:UIView.AnimationOptions = UIView.AnimationOptions(rawValue: animationCurveRaw)

     if endFrameY >= UIScreen.main.bounds.size.height {
       self.keyboardHeightLayoutConstraint?.constant = 0.0
     } else {
       self.keyboardHeightLayoutConstraint?.constant = endFrame?.size.height ?? 0.0
     }

     UIView.animate(
       withDuration: duration,
       delay: TimeInterval(0),
       options: animationCurve,
       animations: { self.view.layoutIfNeeded() },
       completion: nil)
   }
}

I had the same problem and finally figured out, that it was the Logitech SetPoint Software.

Deinstalled it - and the error is gone.

If you are lazy, and have a lot of RAM, create a sieve of Eratosthenes which is practically a giant array from which you kicked all numbers that are not prime. From then on every prime "probability" test will be super quick. The upper limit for this solution for fast results is the amount of you RAM. The upper limit for this solution for superslow results is your hard disk's capacity.

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

You're currently trying to remove the exact string [] - two square brackets with nothing between them. Instead, you want to remove all [ and separately remove all ].

Personally I would avoid using replaceAll here as it introduces more confusion due to the regex part - I'd use:

String replaced = original.replace("[", "").replace("]", "");

Only use the methods which take regular expressions if you really want to do full pattern matching. When you just want to replace all occurrences of a fixed string, replace is simpler to read and understand.

(There are alternative approaches which use the regular expression form and really match patterns, but I think the above code is significantly simpler.)

Simply, you use ADB, as follows:

adb install <path to apk>

The pixel width and height of your page will depend on orientation as well as the meta viewport tag, if specified. Here are the results of running jquery's $(window).width() and $(window).height() on iPad 1 browser.

When page has no meta viewport tag:

• Portrait: 980x1208
• Landscape: 980x661

When page has either of these two meta tags:

<meta name="viewport" content="initial-scale=1,user-scalable=no,maximum-scale=1,width=device-width">

<meta name="viewport" content="initial-scale=1,user-scalable=no,maximum-scale=1">

If i is the int, then

char c = i;

makes it a char. You might want to add a check that the value is <128 if it comes from an untrusted source. This is best done with isascii from <ctype.h>, if available on your system (see @Steve Jessop's comment to this answer).

You get that error because you don't have the public key of the person who signed the message.

gpg should have given you a message containing the ID of the key that was used to sign it. Obtain the public key from the person who encrypted the file and import it into your keyring (gpg2 --import key.asc); you should be able to verify the signature after that.

If the sender submitted its public key to a keyserver (for instance, https://pgp.mit.edu/), then you may be able to import the key directly from the keyserver:

gpg2 --keyserver https://pgp.mit.edu/ --search-keys <sender_name_or_address>

since Authenticity Token is so important, and in Rails 3.0+ you can use

 <%= token_tag nil %>

to create

<input name="authenticity_token" type="hidden" value="token_value">

anywhere

You are checking it the array index contains a string "undefined", you should either use the typeof operator:

typeof predQuery[preId] == 'undefined'

Or use the undefined global property:

predQuery[preId] === undefined

The first way is safer, because the undefined global property is writable, and it can be changed to any other value.

The problem here is that I don't know what is expected. With your current setup, invoking the plugin on the command line would just work:

$ mvn exec:exec
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [exec:exec]
[INFO] ------------------------------------------------------------------------
[INFO] [exec:exec {execution: default-cli}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

The global configuration is used, the hostname command is executed (laptop is my hostname). In other words, the plugin works as expected.

Now, if you want a plugin to get executed as part of the build, you have to bind a goal on a specific phase. For example, to bind it on compile:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
      <execution>
        <id>some-execution</id>
        <phase>compile</phase>
        <goals>
          <goal>exec</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <executable>hostname</executable>
    </configuration>
  </plugin>

And then:

$ mvn compile
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [compile]
[INFO] ------------------------------------------------------------------------
[INFO] [resources:resources {execution: default-resources}]
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] skip non existing resourceDirectory /home/pascal/Projects/Q3491937/src/main/resources
[INFO] [compiler:compile {execution: default-compile}]
[INFO] Nothing to compile - all classes are up to date
[INFO] [exec:exec {execution: some-execution}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

Note that you can specify a configuration inside an execution.

The photos property is an optional array and must be unwrapped before accessing its elements (the same as you do to get the count property of the array):

for var i = 0; i < userPhotos!.count ; ++i {
    let url = userPhotos![i].url
}

Just in case you use a Fragment layout with a ViewPager (TabLayout), you can easily ask for the current (in front) fragment by ViewPager.getCurrentItem() method. It will give you the page index.

Mapping from page index to fragment[class] should be easy as you did the mapping in your FragmentPagerAdapter derived Adapter already.

int i = pager.getCurrentItem();

You may register for page change notifications by

ViewPager pager = (ViewPager) findViewById(R.id.container);
pager.addOnPageChangeListener(this);

Of course you must implement interface ViewPager.OnPageChangeListener

public class MainActivity 
    extends AppCompatActivity
    implements ViewPager.OnPageChangeListener
{
    public void onPageSelected (int position)
    {
        // we get notified here when user scrolls/switches Fragment in ViewPager -- so
        // we know which one is in front.
        Toast toast = Toast.makeText(this, "current page " + String.valueOf(position), Toast.LENGTH_LONG);
        toast.show();
    }

    public void onPageScrolled (int position, float positionOffset, int positionOffsetPixels) {
    }

    public void onPageScrollStateChanged (int state) {
    }
}

My answer here might be a little off the question. But as a newbie to Android Apps I was just facing exactly this problem and did not find an answer anywhere. So worked out above solution and posting it here -- perhaps someone finds it useful.

Edit: You might combine this method with LiveData on which the fragments subscribe. Further on, if you give your Fragments a page index as constructor argument, you can make a simple amIvisible() function in your fragment class.

In MainActivity:

private final MutableLiveData<Integer> current_page_ld = new MutableLiveData<>();
public LiveData<Integer> getCurrentPageIdx() { return current_page_ld; }

public void onPageSelected(int position) {
    current_page_ld.setValue(position);
}

public class MyPagerAdapter extends FragmentPagerAdapter
{
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page: But only on first
        // creation -- not on restore state !!!
        // see: https://stackoverflow.com/a/35677363/3290848
        switch (position) {
            case 0:
                return MyFragment.newInstance(0);
            case 1:
                return OtherFragment.newInstance(1);
            case 2:
                return XYFragment.newInstance(2);
        }
        return null;
    }
}

In Fragment:

    public static MyFragment newInstance(int index) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putInt("idx", index);
        fragment.setArguments(args);
        return fragment;
    }

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mPageIndex = getArguments().getInt(ARG_PARAM1);
        }
        ...
    }
    
    public void onAttach(Context context)
    {
        super.onAttach(context);
        MyActivity mActivity = (MyActivity)context;

        mActivity.getCurrentPageIdx().observe(this, new Observer<Integer>() {
            @Override
            public void onChanged(Integer data) {
                if (data == mPageIndex) {
                    // have focus
                } else {
                    // not in front
                }
            }
        });
    }

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.
