What is a patch?

A patch is little more (see below) than a series of instructions: "add this here", "remove that there", "change this third thing to a fourth". That's why git tells you:

The copy of the patch that failed is found in:
c:/.../project2/.git/rebase-apply/patch

You can open that patch in your favorite viewer or editor, open the files-to-be-changed in your favorite editor, and "hand apply" the patch, using what you know (and git does not) to figure out how "add this here" is to be done when the files-to-be-changed now look little or nothing like what they did when they were changed earlier, with those changes delivered to you as a patch.

A little more

A three-way merge introduces that "little more" information than the plain "series of instructions": it tells you what the original version of the file was as well. If your repository has the original version, your git can compare what you did to a file, to what the patch says to do to the file.

As you saw above, if you request the three-way merge, git can't find the "original version" in the other repository, so it can't even attempt the three-way merge. As a result you get no conflict markers, and you must do the patch-application by hand.

Using --reject

When you have to apply the patch by hand, it's still possible that git can apply most of the patch for you automatically and leave only a few pieces to the entity with the ability to reason about the code (or whatever it is that needs patching). Adding --reject tells git to do that, and leave the "inapplicable" parts of the patch in rejection files. If you use this option, you must still hand-apply each failing patch, and figure out what to do with the rejected portions.

Once you have made the required changes, you can git add the modified files and use git am --continue to tell git to commit the changes and move on to the next patch.

What if there's nothing to do?

Since we don't have your code, I can't tell if this is the case, but sometimes, you wind up with one of the patches saying things that amount to, e.g., "fix the spelling of a word on line 42" when the spelling there was already fixed.

In this particular case, you, having looked at the patch and the current code, should say to yourself: "aha, this patch should just be skipped entirely!" That's when you use the other advice git already printed:

If you prefer to skip this patch, run "git am --skip" instead.

If you run git am --skip, git will skip over that patch, so that if there were five patches in the mailbox, it will end up adding just four commits, instead of five (or three instead of five if you skip twice, and so on).

if you just want diff the specified file, you can :

git diff master 766eceb -- connections/ > 000-mysql-connector.patch

I'd agree it is interesting to propose a particular style of working. However, unless I have the chance to set the style, I usually follow what's been done for consistency.

Taking a look at the Linux Kernel Commits, the project that started git if you like, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=bca476139d2ded86be146dae09b06e22548b67f3, they don't follow the 50/72 rule. The first line is 54 characters.

I would say consistency matters. Set up proper means of identifying users who've made commits (user.name, user.email - especially on internal networks. User@OFFICE-1-PC-10293982811111 isn't a useful contact address). Depending on the project, make the appropriate detail available in the commit. It's hard to say what that should be; it might be tasks completed in a development process, then details of what's changed.

I don't believe users should use git one way because certain interfaces to git treat the commits in certain ways.

I should also note there are other ways to find commits. For a start, git diff will tell you what's changed. You can also do things like git log --pretty=format:'%T %cN %ce' to format the options of git log.

If you want to apply it as a commit, use git am.

It is possible but how depends on what you are trying to accomplish. If it's this:

| Left-aligned       Right-aligned | in one cell then you can use floating divs inside the td tag:

<td>
<div style='float: left; text-align: left'>Left-aligned</div>
<div style='float: right; text-align: right'>Right-aligned</div>
</td>

If it's | Left-aligned
                                           Right Aligned |

Then Balon's solution is correct.

If it's: | Left-aligned    |   Right-Aligned |

Then it's:

<td align="left">Left-aligned</td>
<td align="right">Right-Aligned</td>

Thanks everybody, here is the most succinct explanation I found on the MSDN site:

// y = x, unless x is null, in which case y = -1.
int y = x ?? -1;

I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:

multiDexEnabled true

And it worked!

Example

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

And clean the project.

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

UPDATE:

You can use load() method:

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

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

And you can use an IFRAME:

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

This is slower, but will submit independently.

It require to include Content-Type:application/json in web api request header section when not mention any content then by default it is Content-Type:text/plain passes to request.

Recent updates to ggplot (0.9.2+) have overhauled the syntax for themes. Most notably, opts() is now deprecated, having been replaced by theme(). Sandy's answer will still (as of Jan '12) generates a chart, but causes R to throw a bunch of warnings.

Here's updated code reflecting current ggplot syntax:

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

#base ggplot object
p <- ggplot(df, aes(x = a, y = b))

p +
  #plots the points
  geom_point() +

  #theme with white background
  theme_bw() +

  #eliminates background, gridlines, and chart border
  theme(
    plot.background = element_blank(),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank()
  ) +

  #draws x and y axis line
  theme(axis.line = element_line(color = 'black'))

generates:

var encodedStr = 'hello & world';

var parser = new DOMParser;
var dom = parser.parseFromString(
    '<!doctype html><body>' + encodedStr,
    'text/html');
var decodedString = dom.body.textContent;

console.log(decodedString);

I just found this excellent little tutorial. broken link (Cached version)

I also followed Microsoft's tutorial which is nice, but I only needed pipes as well.

As you can see, you don't need configuration files and all that messy stuff.

By the way, he uses both HTTP and pipes. Just remove all code lines related to HTTP, and you'll get a pure pipe example.

I have spent a lot of time looking for solution for this. And finally managed to do this. Don't forget to upvote @Jason Robinson answer because my is based on his.

So first thing, you sholuld know that since Android 7.0 we have to use FileProvider and something called ContentUri, otherwise you will get an annoying error trying to invoke your Intent. This is sample code:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, getUriFromPath(context, "[Your path to save image]"));
startActivityForResult(intent, CAPTURE_IMAGE_RESULT);

Method getUriFromPath(Context, String) basis on user version of Android create FileUri (file://...) or ContentUri (content://...) and there it is:

public Uri getUriFromPath(Context context, String destination) {
    File file =  new File(destination);

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
        return FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
    } else {
        return Uri.fromFile(file);
    }
}

After onActivityResult you can catch that uri where image is saved by camera, but now you have to detect camera rotation, here we will use moddified @Jason Robinson answer:

First we need to create ExifInterface based on Uri

@Nullable
public ExifInterface getExifInterface(Context context, Uri uri) {
    try {
        String path = uri.toString();
        if (path.startsWith("file://")) {
            return new ExifInterface(path);
        }
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            if (path.startsWith("content://")) {
                InputStream inputStream = context.getContentResolver().openInputStream(uri);
                return new ExifInterface(inputStream);
            }
        }
    }
    catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

Above code can be simplified, but i want to show everything. So from FileUri we can create ExifInterface based on String path, but from ContentUri we can't, Android doesn't support that.

In that case we have to use other constructor based on InputStream. Remember this constructor isn't available by default, you have to add additional library:

compile "com.android.support:exifinterface:XX.X.X"

Now we can use getExifInterface method to get our angle:

public float getExifAngle(Context context, Uri uri) {
    try {
        ExifInterface exifInterface = getExifInterface(context, uri);
        if(exifInterface == null) {
            return -1f;
        }

        int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
                ExifInterface.ORIENTATION_UNDEFINED);

        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_90:
                return 90f;
            case ExifInterface.ORIENTATION_ROTATE_180:
                return 180f;
            case ExifInterface.ORIENTATION_ROTATE_270:
                return 270f;
            case ExifInterface.ORIENTATION_NORMAL:
                return 0f;
            case ExifInterface.ORIENTATION_UNDEFINED:
                return -1f;
            default:
                return -1f;
        }
    }
    catch (Exception e) {
        e.printStackTrace();
        return -1f;
    }
}

Now you have Angle to properly rotate you image :).

I end up having similar issue. So I discovered that the Software PostMan can generate code when clicking the "Code" button at upper/left corner. From that we can see what going on "under the hood" and the HTTP call is generated in many code language; curl command, C# RestShart, java, nodeJs, ...

That helped me a lot and instead of using .Net base HttpClient I ended up using RestSharp nuget package.

Hope that can help someone else!

To cross-correlate 1d arrays use numpy.correlate.

For 2d arrays, use scipy.signal.correlate2d.

There is also scipy.stsci.convolve.correlate2d.

There is also matplotlib.pyplot.xcorr which is based on numpy.correlate.

See this post on the SciPy mailing list for some links to different implementations.

Edit: @user333700 added a link to the SciPy ticket for this issue in a comment.

Add the library from File->Right click->New->Module->Import Eclipse ADT project->brows your library->finish Now add in the app gradle setting following code:

Finally add in the setting gradle following code:

As far as I can see dependencies have changed between 2.26-b03 and 2.26-b04 (HK2 was moved to from compile to testCompile)... there might be some change in the jersey dependencies that has not been completed yet (or which lead to a bug).

However, right now the simple solution is to stick to an older version :-)

This worked for me, curly braces are not required.

ng-style="{'background-image':'url(../../../app/img/notification/'+notification.icon+'.png)'}"

notification.icon here is scope variable.

Use Stringutils.split() to split the string by whites paces. For example StringUtils.split("Hello World") returns "Hello" and "World";

In order to solve the mentioned case we use split method like this

String split[]= StringUtils.split("Hello I'm your String");

when we print the split array the output will be :

Hello

I'm

your

String

Actually the minimum amount of Angular to be used (as requested in the original question) is just adding a class to the DOM element when show variable is true, and perform the animation/transition via CSS.

So your minimum Angular code is this:

<div class="box-opener" (click)="show = !show">
    Open/close the box
</div>

<div class="box" [class.opened]="show">
    <!-- Content -->
</div>

With this solution, you need to create CSS rules for the transition, something like this:

.box {
    background-color: #FFCC55;
    max-height: 0px;
    overflow-y: hidden;
    transition: ease-in-out 400ms max-height;
}

.box.opened {
    max-height: 500px;
    transition: ease-in-out 600ms max-height;
}

If you have retro-browser-compatibility issues, just remember to add the vendor prefixes in the transitions.

See the example here

If you are accessing Oracle with JDBC (Java) you can use DatabaseMetadata class. If you are accessing Oracle with ADO.NET you can use a similar approach.

If you are accessing Oracle with ODBC, you can use SQLTables function.

Otherwise, if you just need the information in SQLPlus or similar Oracle client, one of the queries already mentioned will do. For instance:

select TABLE_NAME from user_tables

Here are brief list:

• JQuery with JSON stuff. (http://www.w3schools.com/xml/xml_http.asp)

• $_SESSION - probably best way

• Custom cookie - will not *always* work.

• HTTP headers - some proxy can block it.

• database such MySQL, Postgres or something else such Redis or Memcached (e.g. similar to home-made session, "locked" by IP address)

• APC - similar to database, will not *always* work.

• HTTP_REFERRER

• URL hash parameter , e.g. http://domain.com/page.php#param - you will need some JavaScript to collect the hash. - gmail heavy use this.

In modern browsers (ECMAScript 5) to get all enumerable properties you can do:

Object.keys(obj) (Check the link to get a snippet for backward compatibility on older browsers)

Or to get also non-enumerable properties:

Object.getOwnPropertyNames(obj)

Check ECMAScript 5 compatibility table

Additional info: What is a enumerable attribute?

Most of the answers here are wrong. The right answer is it depends. For example, here are two C functions which walks through a tree. First the recursive one:

static
void mm_scan_black(mm_rc *m, ptr p) {
    SET_COL(p, COL_BLACK);
    P_FOR_EACH_CHILD(p, {
        INC_RC(p_child);
        if (GET_COL(p_child) != COL_BLACK) {
            mm_scan_black(m, p_child);
        }
    });
}

And here is the same function implemented using iteration:

static
void mm_scan_black(mm_rc *m, ptr p) {
    stack *st = m->black_stack;
    SET_COL(p, COL_BLACK);
    st_push(st, p);
    while (st->used != 0) {
        p = st_pop(st);
        P_FOR_EACH_CHILD(p, {
            INC_RC(p_child);
            if (GET_COL(p_child) != COL_BLACK) {
                SET_COL(p_child, COL_BLACK);
                st_push(st, p_child);
            }
        });
    }
}

It's not important to understand the details of the code. Just that p are nodes and that P_FOR_EACH_CHILD does the walking. In the iterative version we need an explicit stack st onto which nodes are pushed and then popped and manipulated.

The recursive function runs much faster than the iterative one. The reason is because in the latter, for each item, a CALL to the function st_push is needed and then another to st_pop.

In the former, you only have the recursive CALL for each node.

Plus, accessing variables on the callstack is incredibly fast. It means you are reading from memory which is likely to always be in the innermost cache. An explicit stack, on the other hand, has to be backed by malloc:ed memory from the heap which is much slower to access.

With careful optimization, such as inlining st_push and st_pop, I can reach roughly parity with the recursive approach. But at least on my computer, the cost of accessing heap memory is bigger than the cost of the recursive call.

But this discussion is mostly moot because recursive tree walking is incorrect. If you have a large enough tree, you will run out of callstack space which is why an iterative algorithm must be used.

I think the previous answer is the best way to do it here is another simple way. just to print the sorted results.

 String path="/tmp";
 String[] dirListing = null;
 File dir = new File(path);
 dirListing = dir.list();
 Arrays.sort(dirListing);
 System.out.println(Arrays.deepToString(dirListing));

In one line and probably faster then arr.indexOf(Math.max.apply(Math, arr)):

var a = [0, 21, 22, 7];_x000D_
var indexOfMaxValue = a.reduce((iMax, x, i, arr) => x > arr[iMax] ? i : iMax, 0);_x000D_
_x000D_
document.write("indexOfMaxValue = " + indexOfMaxValue); // prints "indexOfMaxValue = 2"

Where:

• iMax - the best index so far (the index of the max element so far, on the first iteration iMax = 0 because the second argument to reduce() is 0, we can't omit the second argument to reduce() in our case)
• x - the currently tested element from the array
• i - the currently tested index
• arr - our array ([0, 21, 22, 7])

About the reduce() method (from "JavaScript: The Definitive Guide" by David Flanagan):

reduce() takes two arguments. The first is the function that performs the reduction operation. The task of this reduction function is to somehow combine or reduce two values into a single value, and to return that reduced value.

Functions used with reduce() are different than the functions used with forEach() and map(). The familiar value, index, and array values are passed as the second, third, and fourth arguments. The first argument is the accumulated result of the reduction so far. On the first call to the function, this first argument is the initial value you passed as the second argument to reduce(). On subsequent calls, it is the value returned by the previous invocation of the function.

When you invoke reduce() with no initial value, it uses the first element of the array as the initial value. This means that the first call to the reduction function will have the first and second array elements as its first and second arguments.

If I have understood it correctly, you are trying to convert a String representing a given date, to another type.

Note: (As @Samson Scharfrichter has mentioned)

• the default representation of a date is ISO8601
• a date is stored in binary (not as a string)

There are a few ways to do it. And you are close to the solution. I would use the CAST (which converts to a DATE_TYPE):

SELECT cast('2018-06-05' as date); 

Result: 2018-06-05 DATE_TYPE

or (depending on your pattern)

select cast(to_date(from_unixtime(unix_timestamp('05-06-2018', 'dd-MM-yyyy'))) as date)

Result: 2018-06-05 DATE_TYPE

And if you decide to convert ISO8601 to a date type:

select cast(to_date(from_unixtime(unix_timestamp(regexp_replace('2018-06-05T08:02:59Z', 'T',' ')))) as date);

Result: 2018-06-05 DATE_TYPE

Hive has its own functions, I have written some examples for the sake of illustration of these date- and cast- functions:

I constructed this approach while looking for how to send a message on a recurring schedule. I found the approach where you reference the Inspector property of the created message did not add the signature I wanted (I have more than one account set up in Outlook, with separate signatures.)

The approach below is fairly flexible and still simple.

    Private Sub Add_Signature(ByVal addy as String, ByVal subj as String, ByVal body as String)
       Dim oMsg As MailItem
       Set oMsg = Application.CreateItem(olMailItem)
       oMsg.To = addy
       oMsg.Subject = subj
       oMsg.Body = body
       Dim sig As String
       ' Mysig is the name you gave your signature in the OL Options dialog 
       sig = ReadSignature("Mysig.htm")
       oMsg.HTMLBody = Item.Body & "<p><BR/><BR/></p>" & sig ' oMsg.HTMLBody
       oMsg.Send
       Set oMsg = Nothing
    End Sub

    Private Function ReadSignature(sigName As String) As String
       Dim oFSO, oTextStream, oSig As Object
       Dim appDataDir, sig, sigPath, fileName As String
       appDataDir = Environ("APPDATA") & "\Microsoft\Signatures"
       sigPath = appDataDir & "\" & sigName

       Set oFSO = CreateObject("Scripting.FileSystemObject")
       Set oTextStream = oFSO.OpenTextFile(sigPath)
       sig = oTextStream.ReadAll
       ' fix relative references to images, etc. in sig
       ' by making them absolute paths, OL will find the image
       fileName = Replace(sigName, ".htm", "") & "_files/"
       sig = Replace(sig, fileName, appDataDir & "\" & fileName)
       ReadSignature = sig
    End Function

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();

You can eventually extend the EL language by using the EL Functor, which will allow you to call any Java beans methods, even with parameters...

This can work too:

chmod -R 755 *  // All files and folders to 755.

chmod -R 644 *.*  // All files will be 644.

I had a workaround for this problem. I created dll project with viewer in vs2015 and used this dll in vs2017. Report showing perfectly.

Based on theDunc's answer but written in Swift with Autolayout.

Probably, there is something wrong with the default region while configuring aws. In your case, the URL says "https://s3.us-east-1a.amazonaws.com/"

In your command prompt,

aws configure, enter your keys, Now fix your region from us-east-1a to us-east-1.

Kindly check the syntax according to the CLI you are using. This will be helpful.

1. Open Run in your system.

2. Type %windir%\System32\cliconfg.exe

3. Click on ok button then check that the "TCP/IP Network Protocol Default Value Setup" pop-up is open.

4. Highlight TCP/IP under the Enabled protocols window.

5. Click the Properties button.

6. Enter the new port number, then click OK.

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

Below is an adaptation of previous code for using under PyQt5 and Matplotlib 2.0. There are a number of small changes: structure of PyQt submodules, other submodule from matplotlib, deprecated method has been replaced...

import sys
from PyQt5.QtWidgets import QDialog, QApplication, QPushButton, QVBoxLayout

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
import matplotlib.pyplot as plt

import random

class Window(QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # a figure instance to plot on
        self.figure = plt.figure()

        # this is the Canvas Widget that displays the `figure`
        # it takes the `figure` instance as a parameter to __init__
        self.canvas = FigureCanvas(self.figure)

        # this is the Navigation widget
        # it takes the Canvas widget and a parent
        self.toolbar = NavigationToolbar(self.canvas, self)

        # Just some button connected to `plot` method
        self.button = QPushButton('Plot')
        self.button.clicked.connect(self.plot)

        # set the layout
        layout = QVBoxLayout()
        layout.addWidget(self.toolbar)
        layout.addWidget(self.canvas)
        layout.addWidget(self.button)
        self.setLayout(layout)

    def plot(self):
        ''' plot some random stuff '''
        # random data
        data = [random.random() for i in range(10)]

        # instead of ax.hold(False)
        self.figure.clear()

        # create an axis
        ax = self.figure.add_subplot(111)

        # discards the old graph
        # ax.hold(False) # deprecated, see above

        # plot data
        ax.plot(data, '*-')

        # refresh canvas
        self.canvas.draw()

if __name__ == '__main__':
    app = QApplication(sys.argv)

    main = Window()
    main.show()

    sys.exit(app.exec_())

From the man page:

-d delim The first character of delim is used to terminate the input line, rather than newline.

You are using -d, which will terminate the input line on the comma. It will not read the rest of the line. That's why $y is empty.

I wanted this to work with selects that I added dynamically to the page, so after a lot of experimentation, I ended up giving all the selects that I wanted to do this with the class "fixedwidth", and then added the following CSS:

table#System_table select.fixedwidth { width: 10em; }
table#System_table select.fixedwidth.clicked { width: auto; }

and this code

<!--[if lt IE 9]>
    <script type="text/javascript">
        jQuery(document).ready(function() {
            jQuery(document).on(
              {
                'mouseenter': function(event) {
                    jQuery(this).addClass('clicked');
                    },
                'focusout change blur': function() {
                    jQuery(this).removeClass('clicked');
                    }
              }, 'select.fixedwidth');
        });
    </script>
<![endif]-->

A couple of things to note:

• In spite of the fact that my selects are all in a table, I had to do "on" to the jQuery(document).on instead of to jQuery('table#System_table').on
• In spite of the fact that the jQuery documentation says to use "mouseleave" instead of "blur", I found that in IE7 when I moved the mouse down the drop down list, it would get a mouseleave event but not a blur.

EDIT 2 (final) : According to the bootstrap 4 documentation, class="font-weight-bold" is what you are looking for.

EDIT : You can use class="font-weight-bold" as shown here (Bootstrap 4 alpha).

I kept the original answer below for clarity purposes.

I am posting this answer because this thread seems to have a lot of visitors, yet it had no proper solution to solve this issue. But there will be soon now a way with Bootstrap 4 :

As this GitHub pull request shows, you will just have to use the text-weight-normal, text-weight-bold and text-weight-italic classes.

This can maybe change until the official stable release. At this date of writing, this pull request is not merged yet in the alpha branch.

I will update this post once Bootstrap v4 has been released.

#!/usr/bin/python

class BinaryTree:
    def __init__(self, left, right, data):
        self.left = left
        self.right = right
        self.data = data


    def pre_order_traversal(root):
        print(root.data, end=' ')

        if root.left != None:
            pre_order_traversal(root.left)

        if root.right != None:
            pre_order_traversal(root.right)

    def in_order_traversal(root):
        if root.left != None:
            in_order_traversal(root.left)
        print(root.data, end=' ')
        if root.right != None:
            in_order_traversal(root.right)

    def post_order_traversal(root):
        if root.left != None:
            post_order_traversal(root.left)
        if root.right != None:
            post_order_traversal(root.right)
        print(root.data, end=' ')

A square is a rectangle where the width equals the height. If the square sets two different sizes for the width and height it violates the square invariant. This is worked around by introducing side effects. But if the rectangle had a setSize(height, width) with precondition 0 < height and 0 < width. The derived subtype method requires height == width; a stronger precondition (and that violates lsp). This shows that though square is a rectangle it is not a valid subtype because the precondition is strengthened. The work around (in general a bad thing) cause a side effect and this weakens the post condition (which violates lsp). setWidth on the base has post condition 0 < width. The derived weakens it with height == width.

Therefore a resizable square is not a resizable rectangle.

If they are separate class files within the same project, then you do not need to have an 'import' statement. Just use the class straight off. If the files are in separate projects, you need to add a reference to the project first before you can use an 'import' statement on it.

If you just want to search a single file name

Just Ctrl+P, then type and choose your one

If you want to open all files whose name contains a particular string

1. Open search panel
2. Put any common words inside those files
3. in 'files to include', put the search string with *, e.g. *Signaller*

Just had the same problem - app was being installed OK, but won't run from Xcode with the "process launch failed: failed to get the task for process".

Turns out my development certificate expired during the night. Regenerating the certificate and the provisioning profiles solved the problem.

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

Your issue is that you have re-defined list as a variable previously in your code. This means that when you do type(tmpDict[key])==list if will return False because they aren't equal.

That being said, you should instead use isinstance(tmpDict[key], list) when testing the type of something, this won't avoid the problem of overwriting list but is a more Pythonic way of checking the type.

First you should use NestedScrollView instead of ScrollView and put the RecyclerView inside NestedScrollView.

Use Custom layout class to measure the height and width of screen:

public class CustomLinearLayoutManager extends LinearLayoutManager {

public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
    super(context, orientation, reverseLayout);
}

private int[] mMeasuredDimension = new int[2];

@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    final int widthMode = View.MeasureSpec.getMode(widthSpec);
    final int heightMode = View.MeasureSpec.getMode(heightSpec);
    final int widthSize = View.MeasureSpec.getSize(widthSpec);
    final int heightSize = View.MeasureSpec.getSize(heightSpec);
    int width = 0;
    int height = 0;
    for (int i = 0; i < getItemCount(); i++) {
        if (getOrientation() == HORIZONTAL) {
            measureScrapChild(recycler, i,
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    heightSpec,
                    mMeasuredDimension);

            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            measureScrapChild(recycler, i,
                    widthSpec,
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }
    switch (widthMode) {
        case View.MeasureSpec.EXACTLY:
            width = widthSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    switch (heightMode) {
        case View.MeasureSpec.EXACTLY:
            height = heightSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    setMeasuredDimension(width, height);
}

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {
    View view = recycler.getViewForPosition(position);
    recycler.bindViewToPosition(view, position);
    if (view != null) {
        RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
        int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                getPaddingLeft() + getPaddingRight(), p.width);
        int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                getPaddingTop() + getPaddingBottom(), p.height);
        view.measure(childWidthSpec, childHeightSpec);
        measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
        measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
        recycler.recycleView(view);
    }
}
}

And implement below code in the activity/fragment of RecyclerView:

 final CustomLinearLayoutManager layoutManager = new CustomLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);

    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(mAdapter);

    recyclerView.setNestedScrollingEnabled(false); // Disables scrolling for RecyclerView, CustomLinearLayoutManager used instead of MyLinearLayoutManager
    recyclerView.setHasFixedSize(false);

    recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);

            int visibleItemCount = layoutManager.getChildCount();
            int totalItemCount = layoutManager.getItemCount();
            int lastVisibleItemPos = layoutManager.findLastVisibleItemPosition();
            Log.i("getChildCount", String.valueOf(visibleItemCount));
            Log.i("getItemCount", String.valueOf(totalItemCount));
            Log.i("lastVisibleItemPos", String.valueOf(lastVisibleItemPos));
            if ((visibleItemCount + lastVisibleItemPos) >= totalItemCount) {
                Log.i("LOG", "Last Item Reached!");
            }
        }
    });

CODE

$('#montant-total-prevu').on("change", function() {

var taille = $('#montant-total-prevu').val().length;

    if (taille > 9) {

//TODO

}

});

I was having the same error, but had a proper connection string. My problem was that the driver was not being used, therefore was optimized out of the compiled war.

Be sure to import the driver:

import com.microsoft.sqlserver.jdbc.SQLServerDriver;

And then to force it to be included in the final war, you can do something like this:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

That line is in the original question. This will also work:

SQLServerDriver driver = new SQLServerDriver();

In my case i declared a function in COM Control .idl file like

[id(1)] HRESULT MyMethod([in]INT param);

but not declared in my interface .h file like this

STDMETHOD(MyMethod)(INT param);

Problem solved by adding above line into my interface .h file

this might help some one .

No, you cannot do that. I invite you to read a POST definition.

Or this page: HTTP, request methods

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

A primitive quick fix that works.

If you only use OpenFileDialog, you can capture the FileName, SafeFileName, then subtract to get folder path:

exampleFileName = ofd.SafeFileName;
exampleFileNameFull = ofd.FileName;
exampleFileNameFolder = ofd.FileNameFull.Replace(ofd.FileName, "");

adb shell
am start -n com.package.name/com.package.name.ActivityName

Or you can use this directly:

adb shell am start -n com.package.name/com.package.name.ActivityName

You can also specify actions to be filter by your intent-filters:

am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName 

I have this in most Node.JS apps. It also works in the browser.

function log() {
  const now = new Date();
  const currentDate = `[${now.toISOString()}]: `;
  const args = Array.from(arguments);
  args.unshift(currentDate);
  console.log.apply(console, args);
}

@SimonBuchan is correct.

Since git 1.8.2, Resources/** !Resources/**/*.foo works.

As MrFancypants mentioned in the comments, if you are using Jupyter (which you should, since it currently supersedes the older IPython Notebook project), things are a little different. For one, there are no profiles any more.

After installing Jupyter, first check your ~/.jupyter folder to see its content. If no config files were migrated from the default IPython profile (as they weren't in my case), create a new one for Jupyter Notebook:

jupyter notebook --generate-config

This generates ~/.jupyter/jupyter_notebook_config.py file with some helpfully commented possible options. To set the default directory add:

c.NotebookApp.notebook_dir = u'/absolute/path/to/notebook/directory'

As I switch between Linux and OS X, I wanted to use a path relative to my home folder (as they differ – /Users/username and /home/username), so I set something like:

import os
c.NotebookApp.notebook_dir = os.path.expanduser('~/Dropbox/dev/notebook')

Now, whenever I run jupyter notebook, it opens my desired notebook folder. I also version the whole ~/.jupyter folder in my dotfiles repository that I deploy to every new work machine.

As an aside, you can still use the --notebook-dir command line option, so maybe a simple alias would suit your needs better.

jupyter notebook --notebook-dir=/absolute/path/to/notebook/directory

This is a very simple adaptation of the modifyList function by Sarkar. Because it is recursive, it will handle more complex situations than mapply would, and it will handle mismatched name situations by ignoring the items in 'second' that are not in 'first'.

appendList <- function (x, val) 
{
    stopifnot(is.list(x), is.list(val))
    xnames <- names(x)
    for (v in names(val)) {
        x[[v]] <- if (v %in% xnames && is.list(x[[v]]) && is.list(val[[v]])) 
            appendList(x[[v]], val[[v]])
        else c(x[[v]], val[[v]])
    }
    x
}

> appendList(first,second)
$a
[1] 1 2

$b
[1] 2 3

$c
[1] 3 4

You could sort the array first (Ascending by default) and then apply np.flip() (https://docs.scipy.org/doc/numpy/reference/generated/numpy.flip.html)

FYI It works with datetime objects as well.

Example:

    x = np.array([2,3,1,0]) 
    x_sort_asc=np.sort(x) 
    print(x_sort_asc)

    >>> array([0, 1, 2, 3])

    x_sort_desc=np.flip(x_sort_asc) 
    print(x_sort_desc)

    >>> array([3,2,1,0])

I know many others have already answered, but I found following is a simple, yet effective single line answer. Though it doesn't look a lot better than others answers here, but if you read it carefully, it has everything you need to know about the method vs function.

A method is a function that has a defined receiver, in OOP terms, a method is a function on an instance of an object.

This is probably the best solution you'll get. Simple and Easy. I learned it on udemy. Suppose you have two images having image id's id1 and id2 respectively and currently the image view is set as id1 and you want to change it to the other image everytime someone clicks in. So this is the basic code in MainActivity.java File

int clickNum=0;
public void click(View view){
clickNum++;
ImageView a=(ImageView)findViewById(R.id.id1);
ImageView b=(ImageView)findViewById(R.id.id2);
if(clickNum%2==1){
  a.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}
else if(clickNum%2==0){
  b.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}

}

I hope this will surely help

Actually you dont need to call document.getElementById() function to get access to your div.

You can use this object directly by id:

text = test.textContent || test.innerText;
alert(text);

You can also import .svg, .jpg, .png, .ttf, etc. files like:

  ReactDOM.render(
      <img src={require("./svg/kiwi.svg")}/>,
      document.getElementById('root')
  );

That's because object values are passed by reference. You can clone the object like this:

var myArray = [];
var myElement = {
  id: 0,
  value: 0
}

myElement.id =0;
myElement.value=1;
myArray[0] = myElement;

var obj = {};
obj = clone(myElement);
obj.id = 2;
obj.value = 3; 

myArray[1] = obj;

function clone(obj){
  if(obj == null || typeof(obj) != 'object')
    return obj;

  var temp = new obj.constructor(); 
  for(var key in obj)
    temp[key] = clone(obj[key]);

  return temp;
}    

console.log(myArray[0]);
console.log(myArray[1]);

Result:

 - id: 0
 - value: 1
 - id: 2
 - value: 3

The best solution to your problem is probably to first export your dataframe to HTML and then convert it using an HTML-to-image tool. The final appearance could be tweaked via CSS.

Popular options for HTML-to-image rendering include:

• WeasyPrint
• wkhtmltopdf/wkhtmltoimage

Let us assume we have a dataframe named df. We can generate one with the following code:

import string
import numpy as np
import pandas as pd


np.random.seed(0)  # just to get reproducible results from `np.random`
rows, cols = 5, 10
labels = list(string.ascii_uppercase[:cols])
df = pd.DataFrame(np.random.randint(0, 100, size=(5, 10)), columns=labels)
print(df)
#     A   B   C   D   E   F   G   H   I   J
# 0  44  47  64  67  67   9  83  21  36  87
# 1  70  88  88  12  58  65  39  87  46  88

Using WeasyPrint

This approach uses a pip-installable package, which will allow you to do everything using the Python ecosystem. One shortcoming of weasyprint is that it does not seem to provide a way of adapting the image size to its content. Anyway, removing some background from an image is relatively easy in Python / PIL, and it is implemented in the trim() function below (adapted from here). One also would need to make sure that the image will be large enough, and this can be done with CSS's @page size property.

The code follows:

import weasyprint as wsp
import PIL as pil


def trim(source_filepath, target_filepath=None, background=None):
    if not target_filepath:
        target_filepath = source_filepath
    img = pil.Image.open(source_filepath)
    if background is None:
        background = img.getpixel((0, 0))
    border = pil.Image.new(img.mode, img.size, background)
    diff = pil.ImageChops.difference(img, border)
    bbox = diff.getbbox()
    img = img.crop(bbox) if bbox else img
    img.save(target_filepath)


img_filepath = 'table1.png'
css = wsp.CSS(string='''
@page { size: 2048px 2048px; padding: 0px; margin: 0px; }
table, td, tr, th { border: 1px solid black; }
td, th { padding: 4px 8px; }
''')
html = wsp.HTML(string=df.to_html())
html.write_png(img_filepath, stylesheets=[css])
trim(img_filepath)

Using wkhtmltopdf/wkhtmltoimage

This approach uses an external open source tool and this needs to be installed prior to the generation of the image. There is also a Python package, pdfkit, that serves as a front-end to it (it does not waive you from installing the core software yourself), but I will not use it.

wkhtmltoimage can be simply called using subprocess (or any other similar means of running an external program in Python). One would also need to output to disk the HTML file.

The code follows:

import subprocess


df.to_html('table2.html')
subprocess.call(
    'wkhtmltoimage -f png --width 0 table2.html table2.png', shell=True)

and its aspect could be further tweaked with CSS similarly to the other approach.

One of the possible reasons is when you load jQuery TWICE ,like:

<script src='..../jquery.js'></script>
....
....
....
....
....
<script src='......./jquery.js'></script>

So, check your source code and remove duplicate jQuery load.

Use the hex code for a non-breaking space. Something like this:

.breadcrumbs a:before {
    content: '>\00a0';
}

Lists are for looping, tuples are for structures i.e. "%s %s" %tuple.

Lists are usually homogeneous, tuples are usually heterogeneous.

Lists are for variable length, tuples are for fixed length.

For those who struggle with this error and git bash on Windows, just use PowerShell where -it works perfectly.

You can get ANY view by using the code below

view.rootView.findViewById(R.id.*name_of_the_view*)

EDIT: This works on Kotlin. In Java, you may need to do something like this=

this.getCurrentFocus().getRootView().findViewById(R.id.*name_of_the_view*);

I learned getCurrentFocus() function from: @JFreeman 's answer

Try this:

KeyValuePair<string,int> current = this.recent.SingleOrDefault(r => r.Key.Equals(dialog.FileName) == true);

if (current.Key == null)
    this.recent.Add(new KeyValuePair<string,int>(dialog.FileName,0));

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

This is the main difference between username variable and whoami command:

C:\Users\user.name>echo %username%
user.name

C:\Users\user.name>whoami
domain\user.name

DOMAIN = bios name of the domain (not fqdn)

One recipe that I have used (described here: Co-Director Network Data Files in GEXF and JSON from OpenCorporates Data via Scraperwiki and networkx ) runs as follows:

• generate a network representation using networkx
• export the network as a JSON file
• import that JSON into to d3.js. (networkx can export both the tree and graph/network representations that d3.js can import).

The networkx JSON exporter takes the form:

from networkx.readwrite import json_graph
import json
print json.dumps(json_graph.node_link_data(G))

Alternatively you can export the network as a GEXF XML file and then import this representation into the sigma.js Javascript visualisation library.

from xml.etree.cElementTree import tostring
writer=gf.GEXFWriter(encoding='utf-8',prettyprint=True,version='1.1draft')
writer.add_graph(G)
print tostring(writer.xml)

There is a plugin called show functions which lists all the function definitions in a file. It also allows you to sort the function so can search them easily.

Sometimes this error occurs when the .ts file is not saved. So make sure all files in the project are saved otherwise try to restart the editor.

This code works for me: check this link
This is my code when i stop and start service in activity

case R.id.buttonStart:
  Log.d(TAG, "onClick: starting srvice");
  startService(new Intent(this, MyService.class));
  break;
case R.id.buttonStop:
  Log.d(TAG, "onClick: stopping srvice");
  stopService(new Intent(this, MyService.class));
  break;
}
}
 }

And in service class:

  @Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onCreate");

    player = MediaPlayer.create(this, R.raw.braincandy);
    player.setLooping(false); // Set looping
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onDestroy");
    player.stop();
}

HAPPY CODING!

plt.axis('scaled')

works well for me.

The Mark Dickinson answer, although complete, didn't work with the float(52.15) case. After some tests, there is the solution that I'm using:

import decimal
        
def value_to_decimal(value, decimal_places):
    decimal.getcontext().rounding = decimal.ROUND_HALF_UP  # define rounding method
    return decimal.Decimal(str(float(value))).quantize(decimal.Decimal('1e-{}'.format(decimal_places)))

(The conversion of the 'value' to float and then string is very important, that way, 'value' can be of the type float, decimal, integer or string!)

Hope this helps anyone.

You're all doing too much work:

right(str(100+@x),2)

-- for a function, same idea: 
--
create function zeroPad( @yourNum int, @wid int)
as 
begin
  return right( 1000000+@yourNum), @wid)
end

First you should ask yourself the following question: Do you really need an int?

The purpose of enums is to have a collection of items (constants), that have a meaning in the code without relying on an external value (like an int). Enums in Java can be used as an argument on switch statments and they can safely be compared using "==" equality operator (among others).

Proposal 1 (no int needed) :

Often there is no need for an integer behind it, then simply use this:

private enum DownloadType{
    AUDIO, VIDEO, AUDIO_AND_VIDEO
}

Usage:

DownloadType downloadType = MyObj.getDownloadType();
if (downloadType == DownloadType.AUDIO) {
    //...
}
//or
switch (downloadType) {
  case AUDIO:  //...
          break;
  case VIDEO: //...
          break;
  case AUDIO_AND_VIDEO: //...
          break;
}

Proposal 2 (int needed) :

Nevertheless, sometimes it may be useful to convert an enum to an int (for instance if an external API expects int values). In this case I would advise to mark the methods as conversion methods using the toXxx()-Style. For printing override toString().

private enum DownloadType {
    AUDIO(2), VIDEO(5), AUDIO_AND_VIDEO(11);
    private final int code;

    private DownloadType(int code) {
        this.code = code;
    }

    public int toInt() {
        return code;
    }

    public String toString() {
        //only override toString, if the returned value has a meaning for the
        //human viewing this value 
        return String.valueOf(code);
    }
}

System.out.println(DownloadType.AUDIO.toInt());           //returns 2
System.out.println(DownloadType.AUDIO);                   //returns 2 via `toString/code`
System.out.println(DownloadType.AUDIO.ordinal());         //returns 0
System.out.println(DownloadType.AUDIO.name());            //returns AUDIO
System.out.println(DownloadType.VIDEO.toInt());           //returns 5
System.out.println(DownloadType.VIDEO.ordinal());         //returns 1
System.out.println(DownloadType.AUDIO_AND_VIDEO.toInt()); //returns 11

Summary

• Don't use an Integer together with an enum if you don't have to.
• Don't rely on using ordinal() for getting an integer of an enum, because this value may change, if you change the order (for example by inserting a value). If you are considering to use ordinal() it might be better to use proposal 1.
• Normally don't use int constants instead of enums (like in the accepted answer), because you will loose type-safety.

Yes. If memory serves me, that should work. Our you could use:

DELETE FROM table WHERE id <> 2

According to the documentation you can simply return false; to break:

$(xml).find("strengths").each(function() {

    if (iWantToBreak)
        return false;
});

You can use this OnLoad or during fetch infos from DB

In HTML Add following code:

<div id="divLoading">
<p id="loading">
    <img src="~/images/spinner.gif">
</p>

In CSS add following Code:

#divLoading {
  margin: 0px;
  display: none;
  padding: 0px;
  position: absolute;
  right: 0px;
  top: 0px;
  width: 100%;
  height: 100%;
  background-color: rgb(255, 255, 255);
  z-index: 30001;
  opacity: 0.8;}

#loading {
   position: absolute;
   color: White;
  top: 50%;
  left: 45%;}

if you want to show and hide from JS:

  document.getElementById('divLoading').style.display = 'none'; //Not Visible
  document.getElementById('divLoading').style.display = 'block';//Visible

For a dictionary of strings such as the one you're dealing with, it could be done using only Python's built-in text processing capabilities.

(Note this wouldn't work if the values are something else.)

with open('members.txt') as file:
    mdict={}
    for line in file:
        a, b, c, d = line.strip().split(':')
        mdict[a] = b + ':' + c + ':' + d

a = input('ID: ')
if a not in mdict:
    print('ID {} not found'.format(a))
else:
    b, c, d = mdict[a].split(':')
    d = input('phone: ')
    mdict[a] = b + ':' + c + ':' + d  # update entry
    with open('members.txt', 'w') as file:  # rewrite file
        for id, values in mdict.items():
            file.write(':'.join([id] + values.split(':')) + '\n')

Let me explain backwards:

Consider this...

foo()

... as syntactic sugar for:

foo.__call__()

Where foo can be any object that responds to __call__. When I say any object, I mean it: built-in types, your own classes and their instances.

In the case of built-in types, when you write:

int('10')
unicode(10)

You're essentially doing:

int.__call__('10')
unicode.__call__(10)

That's also why you don't have foo = new int in Python: you just make the class object return an instance of it on __call__. The way Python solves this is very elegant in my opinion.

If you need to search for all element's positions between certain indices, you can state them:

[i for i,x in enumerate([1,2,3,2]) if x==2 & 2<= i <=3] # -> [3]

Take a look at this discussion which handles manually hiding and showing the IME. However, my feeling is that if a focused EditText is not bringing the IME up it is because you are calling AlertDialog.show() in your OnCreate() or some other method which is evoked before the screen is actually presented. Moving it to OnPostResume() should fix it in that case I believe.

I through vnc to understand the X11 more. To specify the display to get a many-displayed program, export DISPLAY=IP:DisplayNum.ScreenNum

For example,

vncserver :2
vncserver -list
echo '$DISPLAY'=$DISPLAY 
export DISPLAY=:2  # export DISPLAY=IP:DisplayNum or export DISPLAY=:DisplayNum for localhost; So that can vnc connect and see the vnc desktop :2 if $DISPLAY is not :2.
echo '$DISPLAY'=$DISPLAY

This property will register an OpenEntityManagerInViewInterceptor, which registers an EntityManager to the current thread, so you will have the same EntityManager until the web request is finished. It has nothing to do with a Hibernate SessionFactory etc.

Firstly you need to create AdminClient bean:

 @Bean
 public AdminClient adminClient(){
   Map<String, Object> configs = new HashMap<>();
   configs.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG,
   StringUtils.arrayToCommaDelimitedString(new Object[]{"your bootstrap server address}));
   return AdminClient.create(configs);
 }

Then, you can use this script:

while (true) {
   Map<String, ConsumerGroupDescription> groupDescriptionMap =
         adminClient.describeConsumerGroups(Collections.singletonList(groupId))
         .all()
         .get(10, TimeUnit.SECONDS);

   ConsumerGroupDescription consumerGroupDescription = groupDescriptionMap.get(groupId);

   log.debug("Kafka consumer group ({}) state: {}",
                groupId,
                consumerGroupDescription.state());

   if (consumerGroupDescription.state().equals(ConsumerGroupState.STABLE)) {
        boolean isReady = true;
        for (MemberDescription member : consumerGroupDescription.members()) {
            if (member.assignment() == null || member.assignment().topicPartitions().isEmpty()) {
            isReady = false;
            }
        }

        if (isReady) {
            break;
           }
        }

        log.debug("Kafka consumer group ({}) is not ready. Waiting...", groupId);
        TimeUnit.SECONDS.sleep(1);
}

This script will check the state of the consumer group every second till the state will be STABLE. Because all consumers assigned to topic partitions, you can conclude that server is running and ready.

Super EASY way to close a Pull Request - LATEST!

1. Navigate to the Original Repository where the pull request has been submitted to.
2. Select the Pull requests tab
3. Select your pull request that you wish to remove. This will open it up.
4. Towards the bottom, just enter a valid comment for closure and press Close Pull Request button

nVarchar2 is a Unicode-only storage.

Though both data types are variable length String datatypes, you can notice the difference in how they store values. Each character is stored in bytes. As we know, not all languages have alphabets with same length, eg, English alphabet needs 1 byte per character, however, languages like Japanese or Chinese need more than 1 byte for storing a character.

When you specify varchar2(10), you are telling the DB that only 10 bytes of data will be stored. But, when you say nVarchar2(10), it means 10 characters will be stored. In this case, you don't have to worry about the number of bytes each character takes.

Divide by 2 to the power of 20, (1024*1024) bytes = 1 megabyte

1024*1024 = 1,048,576   
2^20 = 1,048,576
1,048,576/1,048,576 = 1  

It is the same thing.

You can interactively stash single lines with git stash -p (analogous to git add -p).

It doesn't take a filename, but you could just skip other files with d until you reached the file you want stashed and the stash all changes in there with a.

I would suggest editing the /etc/default/jenkins

vi /etc/default/jenkins

And changing the $JENKINS_HOME variable (around line 23) to

JENKINS_HOME=/home/jenkins

Then restart the Jenkins with usual

/etc/init.d/jenkins start

Cheers!

Global exclusions look like they're being worked on, but until then...

From the Sonatype maven reference (bottom of the page):

Dependency management in a top-level POM is different from just defining a dependency on a widely shared parent POM. For starters, all dependencies are inherited. If mysql-connector-java were listed as a dependency of the top-level parent project, every single project in the hierarchy would have a reference to this dependency. Instead of adding in unnecessary dependencies, using dependencyManagement allows you to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. In other words, the dependencyManagement element is equivalent to an environment variable which allows you to declare a dependency anywhere below a project without specifying a version number.

As an example:

  <dependencies>
    <dependency>
      <groupId>commons-httpclient</groupId>
      <artifactId>commons-httpclient</artifactId>
      <version>3.1</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>3.0.5.RELEASE</version>
    </dependency>
  </dependencies>
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
      <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
    </dependencies>
  </dependencyManagement>

It doesn't make the code less verbose overall, but it does make it less verbose where it counts. If you still want it less verbose you can follow these tips also from the Sonatype reference.

You could try removing any alphanumeric characters and space. And then use -n will give you the line number. Try following:

grep -vn "^[a-zA-Z0-9 ]*$" application.log

Remote update

You need to run

git remote update

or

git remote update <remote> 

Then you can run git branch -r to list the remote branches.

Checkout a new branch

To track a (new) remote branch as a local branch:

git checkout -b <local branch> <remote>/<remote branch>

or (sometimes it doesn't work without the extra remotes/):

git checkout -b <local branch> remotes/<remote>/<remote branch>

Helpful git cheatsheets

• Git Cheat Sheet (My personal favorite)
• Some notes on git
• Git Cheat Sheet (pdf)

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

For me the error occurred due to my browser using a cached version of the js file containing the module. Clearing the cache and reloading the page solved the problem.

Every maven project should stop depending on xerces, they probably don't really. XML APIs and an Impl has been part of Java since 1.4. There is no need to depend on xerces or XML APIs, its like saying you depend on Java or Swing. This is implicit.

If I was boss of a maven repo I'd write a script to recursively remove xerces dependencies and write a read me that says this repo requires Java 1.4.

Anything that actually breaks because it references Xerces directly via org.apache imports needs a code fix to bring it up to Java 1.4 level (and has done since 2002) or solution at JVM level via endorsed libs, not in maven.

You can concatenate the arrays with +, building a new array

let c = a + b
print(c) // [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]

or append one array to the other with += (or append):

a += b

// Or:
a.append(contentsOf: b)  // Swift 3
a.appendContentsOf(b)    // Swift 2
a.extend(b)              // Swift 1.2

print(a) // [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]

First check if there is any connectivity problem and you can reach the SMTP server:

In terminal type:

telnet servername portnumber 

If you receive the 220 response you can reach the SMTP server and there is no connectivity problem but if the connection to the server failed see what's wrong in your network.

If the server needs auth try to authenticate on the server by username and password and see if something goes wrong.

At last see if the server requires encryption and if yes openssl and other stuff are configured correctly.

You can get value by using id for that element in onclick function

function dosomething(){
     var buttonValue = document.getElementById('buttonId').value;
}

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.

Try this

products.sort(function (a, b) {
  return a.title.rendered - b.title.rendered;
});

OR

You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.

Using underscore: (below one is just an example)

import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title'); 

Check out NanoHttpd

NanoHTTPD is a light-weight HTTP server designed for embedding in other applications, released under a Modified BSD licence.

It is being developed at Github and uses Apache Maven for builds & unit testing"

You have multiple options. Two options are the following.

numpy.sum(boolarr)
numpy.count_nonzero(boolarr)

Here's an example:

>>> import numpy as np
>>> boolarr = np.array([[0, 0, 1], [1, 0, 1], [1, 0, 1]], dtype=np.bool)
>>> boolarr
array([[False, False,  True],
       [ True, False,  True],
       [ True, False,  True]], dtype=bool)

>>> np.sum(boolarr)
5

Of course, that is a bool-specific answer. More generally, you can use numpy.count_nonzero.

>>> np.count_nonzero(boolarr)
5

function poll(){
    $("ajax.php", function(data){
        //do stuff  
    }); 
}

setInterval(function(){ poll(); }, 5000);

You will need to change the configure port of either Apache or Nginx. After you do this you will need to restart the reconfigured servers, using the 'service' command you used.

Apache

Edit

sudo subl /etc/apache2/ports.conf 

and change the 80 on the following line to something different :

Listen 80

If you just change the port or add more ports here, you will likely also have to change the VirtualHost statement in

sudo subl /etc/apache2/sites-enabled/000-default.conf

and change the 80 on the following line to something different :

<VirtualHost *:80>

then restart by :

sudo service apache2 restart

Nginx

Edit

/etc/nginx/sites-enabled/default

and change the 80 on the following line :

listen 80;

then restart by :

sudo service nginx restart

I'm using version 4.0.3 of MAMP along with phpmyadmin. The top of /Applications/MAMP/bin/phpMyAdmin/libraries/config.default.php reads:

DO NOT EDIT THIS FILE, EDIT config.inc.php INSTEAD !!!

Changing the following line in /Applications/MAMP/bin/phpMyAdmin/config.inc.php and restarting MAMP worked for me.

$cfg['ExecTimeLimit'] = 0;

df.columnname[1].split('.', 1)

This will split data with the first occurrence of '.' in the string or data frame column value.

This should get you started

 <div class="menuBar">
        <img class="logo" src="logo.jpg"/>
        <div class="nav"> 
            <ul>
                <li>Menu1</li>
                <li>Menu 2</li>
                <li>Menu 3</li>
            </ul> 
        </div>
    </div>



body{
    margin-top:50px;}
.menuBar{
    width:100%;
    height:50px;
    display:block;
    position:absolute;
    top:0;
    left:0;
    }
.logo{
    float:left;
    }
.nav{
    float:right;
    margin-right:10px;}
.nav ul li{
    list-style:none;
    float:left;
    }

To find a particular dropdown box element:

Select gender = new Select(driver.findElement(By.id("gender")));

To get the list of all the elements contained in the dropdown box:

for(int j=1;j<3;j++)
    System.out.println(gender.getOptions().get(j).getText());

To select it through visible text displayed when you click on it:

gender.selectByVisibleText("Male");

To select it by index (starting at 0):

gender.selectByIndex(1);

With a small change of the markup, here's my approach (I've just inserted a span inside the paragraph):

.marquee {
  width: 450px;
  margin: 0 auto;
  overflow: hidden;
  box-sizing: border-box;
}

.marquee span {
  display: inline-block;
  width: max-content;

  padding-left: 100%;
  /* show the marquee just outside the paragraph */
  will-change: transform;
  animation: marquee 15s linear infinite;
}

.marquee span:hover {
  animation-play-state: paused
}


@keyframes marquee {
  0% { transform: translate(0, 0); }
  100% { transform: translate(-100%, 0); }
}


/* Respect user preferences about animations */

@media (prefers-reduced-motion: reduce) {
  .marquee span {
    animation-iteration-count: 1;
    animation-duration: 0.01; 
    /* instead of animation: none, so an animationend event is 
     * still available, if previously attached.
     */
    width: auto;
    padding-left: 0;
  }
}

<p class="marquee">
   <span>
       When I had journeyed half of our life's way, I found myself
       within a shadowed forest, for I had lost the path that 
       does not stray. – (Dante Alighieri, <i>Divine Comedy</i>. 
       1265-1321)
   </span>
   </p>

No hardcoded values — dependent on paragraph width — have been inserted.

The animation applies the CSS3 transform property (use prefixes where needed) so it performs well.

If you need to insert a delay just once at the beginning then also set an animation-delay. If you need instead to insert a small delay at every loop then try to play with an higher padding-left (e.g. 150%)

IEnumerable is an interface, instead of looking for how to create an interface instance, create an implementation that matches the interface: create a list or an array.

IEnumerable<string> myStrings = new [] { "first item", "second item" };
IEnumerable<string> myStrings = new List<string> { "first item", "second item" };

For the CTRL+C case, you can use this:

// Tell the system console to handle CTRL+C by calling our method that
// gracefully shuts down.
Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);


static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
            Console.WriteLine("Shutting down...");
            // Cleanup here
            System.Threading.Thread.Sleep(750);
}

If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

Your data is already an object. No need to parse it. The javascript interpreter has already parsed it for you.

var cur_ques_details ={"ques_id":15,"ques_title":"jlkjlkjlkjljl"};
document.write(cur_ques_details['ques_title']);

actually , this has turned out to be couple of javascript changes in the code. calling of javascript method with ; at the end. placing script tags in body instead of head. and interestingly even change the text displayed (please "click") to something that is not an event. so Please rate etc.

turned debugger on safari, it didnot give much information or even errors at times.

The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.

By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.

The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.

Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float

Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.

If you want to keep the float, for whatever reason, you can use clear on the 2nd div to reset the floating properties of elements before that element.
clear has 5 valid values: none | left | right | both | inherit. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element

Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...

<div id="wrapper">
    <div id="inner1"></div>
    <div id="inner2"></div>
</div>

CSS is

#wrapper{
    margin-left:auto;
    margin-right:auto;
    height:auto; // this is not needed, as parent container, this div will size automaticly
    width:auto; // this is not needed, as parent container, this div will size automaticly
}

/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
    border: 1px solid black;
}

Try this:

git init  
git remote add origin your_repo.git  
git remote -v  
git status  

Actually, the simplest thing (in GNU sed, at least) is to use a different separator for the sed substitution (s) command. So, instead of s/pattern/'$mypath'/ being expanded to s/pattern//my/path/, which will of course confuse the s command, use s!pattern!'$mypath'!, which will be expanded to s!pattern!/my/path!. I’ve used the bang (!) character (or use anything you like) which avoids the usual, but-by-no-means-your-only-choice forward slash as the separator.

A more public way is by calling get_form in Admin classes. It also works for non-database fields too. For example here i have a field called '_terminal_list' on the form that can be used in special cases for choosing several terminal items from get_list(request), then filtering based on request.user:

class ChangeKeyValueForm(forms.ModelForm):  
    _terminal_list = forms.ModelMultipleChoiceField( 
queryset=Terminal.objects.all() )

    class Meta:
        model = ChangeKeyValue
        fields = ['_terminal_list', 'param_path', 'param_value', 'scheduled_time',  ] 

class ChangeKeyValueAdmin(admin.ModelAdmin):
    form = ChangeKeyValueForm
    list_display = ('terminal','task_list', 'plugin','last_update_time')
    list_per_page =16

    def get_form(self, request, obj = None, **kwargs):
        form = super(ChangeKeyValueAdmin, self).get_form(request, **kwargs)
        qs, filterargs = Terminal.get_list(request)
        form.base_fields['_terminal_list'].queryset = qs
        return form

I did all of the suggested stuff here and my code still did not work because I was using curl

If you are using curl in the php file, curl seems to reject all ssl traffic by default. A quick-fix that worked for me was to add:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

before calling:

 curl_exec():

in the php file.

I believe that this disables all verification of SSL certificates.

The idea of mapping an function to array of data comes from functional programming. You shouldn't think about array_map as a foreach loop that calls a function on each element of the array (even though that's how it's implemented). It should be thought of as applying the function to each element in the array independently.

In theory such things as function mapping can be done in parallel since the function being applied to the data should ONLY affect the data and NOT the global state. This is because an array_map could choose any order in which to apply the function to the items in (even though in PHP it doesn't).

array_walk on the other hand it the exact opposite approach to handling arrays of data. Instead of handling each item separately, it uses a state (&$userdata) and can edit the item in place (much like a foreach loop). Since each time an item has the $funcname applied to it, it could change the global state of the program and therefor requires a single correct way of processing the items.

Back in PHP land, array_map and array_walk are almost identical except array_walk gives you more control over the iteration of data and is normally used to "change" the data in-place vs returning a new "changed" array.

array_filter is really an application of array_walk (or array_reduce) and it more-or-less just provided for convenience.

RESTful API (Route):

rtr.route('/testing')
.get((req, res)=>{
    res.render('test')
})
.post((req, res, next)=>{
       res.render('test')
})

AJAX Code:

$(function(){
$('#anyid').on('click', function(e){
    e.preventDefault()
    $.ajax({
        url: '/testing',
        method: 'GET',
        contentType: 'application/json',
        success: function(res){
            console.log('GET Request')
        }
    })
})

$('#anyid').on('submit', function(e){
    e.preventDefault()
    $.ajax({
        url: '/testing',
        method: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({
            info: "put data here to pass in JSON format."
        }),
        success: function(res){
            console.log('POST Request')
        }
    })
})
})

Try running

lsof | grep /mnt/data

That should list any process that is accessing /mnt/data that would prevent it from being unmounted.

You can use the FileStream.Write(byte[] array, int offset, int count) method to write it out.

If your array name is "myArray" the code would be.

myStream.Write(myArray, 0, myArray.count);

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

http://docs.python.org/2/howto/unicode.html

To exclude the lines that contain any of the strings in $arrayOfStringsNotInterestedIn, you should use:

(Get-Content $FileName) -notmatch [String]::Join('|',$arrayofStringsNotInterestedIn)

The code proposed by Chris only works if $arrayofStringsNotInterestedIn contains the full lines you want to exclude.

Using a supposed name property as the map key:

for (Product p: productList) { s.put(p.getName(), p); }

Found the solution here

Lets say you have span1 as <span id='span1'>my text</span>
text change events can be captured with:

$(document).ready(function(){
    $("#span1").on('DOMSubtreeModified',function(){
         // text change handler
     });

 });
 

I assume your game has a main loop, and all your sprites are in a list called sprites.

In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event.

while ... # your main loop
  # get all events
  ev = pygame.event.get()

  # proceed events
  for event in ev:

    # handle MOUSEBUTTONUP
    if event.type == pygame.MOUSEBUTTONUP:
      pos = pygame.mouse.get_pos()

      # get a list of all sprites that are under the mouse cursor
      clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
      # do something with the clicked sprites...

So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().

Pygame does not offer event driven programming, as e.g. cocos2d does.

Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.

if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
  print ("You have opened a chest!")

You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.

handled = False

while ... // your loop

  if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
    print ("You have opened a chest!")
    handled = pygame.mouse.get_pressed()[0]

Of course you can subclass Sprite and add a method called is_clicked like this:

class MySprite(Sprite):
  ...

  def is_clicked(self):
    return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())

So, it's better to use the first approach IMHO.

For query: SELECT * FROM (SELECT id, product FROM product) as product you can use:

$sub_query_from = '(SELECT id, product FROM product ) as product';
$this->db->select();
$this->db->from($sub_query_from);
$query = $this->db->get()

Please notice, that in sub_query_from string you must use spaces between ... product ) as...

For Asp.Net core you better use

<partial name="_MyPartialView" model="MyModel" />

So for example

@foreach (var item in Model)
{
   <partial name="_MyItemView" model="item" />
}

This will give a generator of working days, of course without holidays, stop is datetime.datetime object. If you need holidays just make additional argument with list of holidays and check with 'IFology' ;-)

def workingdays(stop, start=datetime.date.today()):
    while start != stop:
        if start.weekday() < 5:
            yield start
        start += datetime.timedelta(1)

Later on you can count them like

workdays = workingdays(datetime.datetime(2015, 8, 8))
len(list(workdays))

Yes. You just have to use the RAISE_APPLICATION_ERROR function. If you also want to name your exception, you'll need to use the EXCEPTION_INIT pragma in order to associate the error number to the named exception. Something like

  3    PRAGMA EXCEPTION_INIT( ex_custom, -20001 );

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Another way is to pass a reference of your setter from the parent as a prop to the child component, similar to how they do it in React. Say, you have a method updateValue on the parent to update the value, you could instantiate the child component like so: <child :updateValue="updateValue"></child>. Then on the child you will have a corresponding prop: props: {updateValue: Function}, and in the template call the method when the input changes: <input @input="updateValue($event.target.value)">.

\d+

\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"

Assuming your "states" collection is like:

{"name" : "Spain", "cities" : [ { "name" : "Madrid" }, { "name" : null } ] }
{"name" : "France" }

The query to find states with null cities would be:

db.states.find({"cities.name" : {"$eq" : null, "$exists" : true}});

It is a common mistake to query for nulls as:

db.states.find({"cities.name" : null});

because this query will return all documents lacking the key (in our example it will return Spain and France). So, unless you are sure the key is always present you must check that the key exists as in the first query.

If you are specifically looking for getting the difference between two files, then this might help:

with open('first_file', 'r') as file1:
    with open('second_file', 'r') as file2:
        difference = set(file1).difference(file2)

difference.discard('\n')

with open('diff.txt', 'w') as file_out:
    for line in difference:
        file_out.write(line)

TL;DR: Use StandardError instead for general exception catching. When the original exception is re-raised (e.g. when rescuing to log the exception only), rescuing Exception is probably okay.

Exception is the root of Ruby's exception hierarchy, so when you rescue Exception you rescue from everything, including subclasses such as SyntaxError, LoadError, and Interrupt.

Rescuing Interrupt prevents the user from using CTRLC to exit the program.

Rescuing SignalException prevents the program from responding correctly to signals. It will be unkillable except by kill -9.

Rescuing SyntaxError means that evals that fail will do so silently.

All of these can be shown by running this program, and trying to CTRLC or kill it:

loop do
  begin
    sleep 1
    eval "djsakru3924r9eiuorwju3498 += 5u84fior8u8t4ruyf8ihiure"
  rescue Exception
    puts "I refuse to fail or be stopped!"
  end
end

Rescuing from Exception isn't even the default. Doing

begin
  # iceberg!
rescue
  # lifeboats
end

does not rescue from Exception, it rescues from StandardError. You should generally specify something more specific than the default StandardError, but rescuing from Exception broadens the scope rather than narrowing it, and can have catastrophic results and make bug-hunting extremely difficult.

If you have a situation where you do want to rescue from StandardError and you need a variable with the exception, you can use this form:

begin
  # iceberg!
rescue => e
  # lifeboats
end

which is equivalent to:

begin
  # iceberg!
rescue StandardError => e
  # lifeboats
end

One of the few common cases where it’s sane to rescue from Exception is for logging/reporting purposes, in which case you should immediately re-raise the exception:

begin
  # iceberg?
rescue Exception => e
  # do some logging
  raise # not enough lifeboats ;)
end

I know the OP is asking for a mysql answer but since I found the other answers not working for me,

• Most of them fail with order by
• Or they are simply very inefficient and make your query very slow for a fat table

So to save time for others like me, just index the row after retrieving them from database

example in PHP:

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1;
}

example in PHP using offset and limit for paging:

$limit = 20; //page size
$offset = 3; //page number

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1+($limit*($offset-1));
}

     @Override
     public String toString() {
          return String.format("%15s /n %15d /n %15s /n %15s", name, age, Occupation, status);
     }

Why not just use all Lambda syntax?

database.Stores.Where(s => s.CompanyID == curCompany.ID)
               .Select(s => new SelectListItem
                   {
                       Value = s.Name,
                       Text = s.ID
                   });

I suggest you take the other way around approach.

Instead of extending the existing enumeration, create a larger one and create a subset of it. For exemple if you had an enumeration called PET and you wanted to extend it to ANIMAL you should do this instead:

public enum ANIMAL {
    WOLF,CAT, DOG
} 
EnumSet<ANIMAL> pets = EnumSet.of(ANIMAL.CAT, ANIMAL.DOG);

Be careful, pets is not an immutable collections, you might want to use Guava or Java9 for more safety.

If I understand correctly, you want to have one class implement multiple of those interfaces with different input/output parameters? This will not work in Java, because the generics are implemented via erasure.

The problem with the Java generics is that the generics are in fact nothing but compiler magic. At runtime, the classes do not keep any information about the types used for generic stuff (class type parameters, method type parameters, interface type parameters). Therefore, even though you could have overloads of specific methods, you cannot bind those to multiple interface implementations which differ in their generic type parameters only.

In general, I can see why you think that this code has a smell. However, in order to provide you with a better solution, it would be necessary to know a little more about your requirements. Why do you want to use a generic interface in the first place?

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, it can tell if one of the Runnables passed along by the Choreographer.post* apis doesn't finish in one frame's time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message "The application may be doing too much work on its main thread." could be misleading.

Put them in brackets []:

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

To achieve a generic solution, why not do this:

$(':reset').live('click', function(){
    var $r = $(this);
    setTimeout(function(){ 
        $r.closest('form').find('.select2-offscreen').trigger('change'); 
    }, 10);
});

This way: You'll not have to make a new logic for each select2 on your application.

And, you don't have to know the default value (which, by the way, does not have to be "" or even the first option)

Finally, setting the value to :selected would not always achieve a true reset, since the current selected might well have been set programmatically on the client, whereas the default action of the form select is to return input element values to the server-sent ones.

EDIT: Alternatively, considering the deprecated status of live, we could replace the first line with this:

$('form:has(:reset)').on('click', ':reset', function(){

or better still:

$('form:has(:reset)').on('reset', function(){

PS: I personally feel that resetting on reset, as well as triggering blur and focus events attached to the original select, are some of the most conspicuous "missing" features in select2!

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

The CORS issue should be fixed in the backend. Temporary workaround uses this option.

1. Go to C:\Program Files\Google\Chrome\Application

2. Open command prompt

3. Execute the command chrome.exe --disable-web-security --user-data-dir="c:/ChromeDevSession"

Using the above option, you can able to open new chrome without security. this chrome will not throw any cors issue.

Here's my 2 cents: I had the same problem and I tried using Notepad++ to convert to UTF-8 no BOM, and also the old "copy to MS notepad then back again" trick, all to no avail. My problem was solved by making sure all files (and 'included' files) were the same file system; I had some files that were Windows format and some that had been copied off a remote Linux server, so were in UNIX format.

One division is

• scripting = dynamically interpreted
• normal = compiled

A dynamically interpreted language is interpreted at runtime whereas a compiled language is compiled before execution.

I should add that as Jörg has pointed out, the interpreted / compiled distinction is not a feature of the language, but of the execution engine.

You might also be interested in this explanation of Type system, which is related and focuses more on the language aspect, instead of the execution engine. Most scripting languages are dynamically typed, whereas "normal" languages are mostly statically typed.

In general the division of statically vs dynamically typed languages is better defined and has more implications on the usability of the language.

I found this question while looking for a way to have fine grained flow control to break from a specific block of code. The solution I settled on wasn't mentioned...

Using labels with the break keyword

From: about_break

A Break statement can include a label that lets you exit embedded loops. A label can specify any loop keyword, such as Foreach, For, or While, in a script.

Here's a simple example

:myLabel for($i = 1; $i -le 2; $i++) {
        Write-Host "Iteration: $i"
        break myLabel
}

Write-Host "After for loop"

# Results:
# Iteration: 1
# After for loop

And then a more complicated example that shows the results with nested labels and breaking each one.

:outerLabel for($outer = 1; $outer -le 2; $outer++) {

    :innerLabel for($inner = 1; $inner -le 2; $inner++) {
        Write-Host "Outer: $outer / Inner: $inner"
        #break innerLabel
        #break outerLabel
    }

    Write-Host "After Inner Loop"
}

Write-Host "After Outer Loop"

# Both breaks commented out
# Outer: 1 / Inner: 1
# Outer: 1 / Inner: 2
# After Inner Loop
# Outer: 2 / Inner: 1
# Outer: 2 / Inner: 2
# After Inner Loop
# After Outer Loop

# break innerLabel Results
# Outer: 1 / Inner: 1
# After Inner Loop
# Outer: 2 / Inner: 1
# After Inner Loop
# After Outer Loop

# break outerLabel Results
# Outer: 1 / Inner: 1
# After Outer Loop

You can also adapt it to work in other situations by wrapping blocks of code in loops that will only execute once.

:myLabel do {
    1..2 | % {

        Write-Host "Iteration: $_"
        break myLabel

    }
} while ($false)

Write-Host "After do while loop"

# Results:
# Iteration: 1
# After do while loop

You don't need an IIF() at all here. The comparisons return true or false anyway.

Also, since this row visibility is on a group row, make sure you use the same aggregate function on the fields as you use in the fields in the row. So if your group row shows sums, then you'd put this in the Hidden property.

=Sum(Fields!OpeningStock.Value) = 0 And
Sum(Fields!GrossDispatched.Value) = 0 And 
Sum(Fields!TransferOutToMW.Value) = 0 And
Sum(Fields!TransferOutToDW.Value) = 0 And
Sum(Fields!TransferOutToOW.Value) = 0 And
Sum(Fields!NetDispatched.Value) = 0 And
Sum(Fields!QtySold.Value) = 0 And
Sum(Fields!StockAdjustment.Value) = 0 And
Sum(Fields!ClosingStock.Value) = 0

But with the above version, if one record has value 1 and one has value -1 and all others are zero then sum is also zero and the row could be hidden. If that's not what you want you could write a more complex expression:

=Sum(
    IIF(
        Fields!OpeningStock.Value=0 AND
        Fields!GrossDispatched.Value=0 AND
        Fields!TransferOutToMW.Value=0 AND
        Fields!TransferOutToDW.Value=0 AND 
        Fields!TransferOutToOW.Value=0 AND
        Fields!NetDispatched.Value=0 AND
        Fields!QtySold.Value=0 AND
        Fields!StockAdjustment.Value=0 AND
        Fields!ClosingStock.Value=0,
        0,
        1
    )
) = 0

This is essentially a fancy way of counting the number of rows in which any field is not zero. If every field is zero for every row in the group then the expression returns true and the row is hidden.

Using MAMP I changed the host=localhost to host=127.0.0.1. But a new issue came "connection refused"

Solved this by putting 'port' => '8889', in 'Datasources' => [

// This allows us to resize the image. It prevents skewed images and 
// also vertically long images caused by trying to maintain the aspect

    FullsizeImage.RotateFlip(System.Drawing.RotateFlipType.Rotate180FlipNone);

    int NewHeight = FullsizeImage.Height * NewWidth / FullsizeImage.Width;
    if (NewHeight > MaxHeight)

        // Resize with height instead
        NewWidth = FullsizeImage.Width * MaxHeight / FullsizeImage.Height;

    }

The non-greedy ? works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .. You need to tell them explicitly that you want to match line-breaks too with .

For example,

<img\s.*?>

works fine!

Check the results here.

Also, read about how dot behaves in various regex flavours.

String host = <host name>
String port = <port>
String service = <service name>
String dbName = <db schema>+"."+service
String url = "jdbc:oracle:thin:@"+host+":"+"port"+"/"+dbName

An interesting example is you can continuously see a counter/stop-watch running in separate thread. Also showing GPS-Location. While main activity User Interface Thread is already there.

Excerpt:

try {    
    cnt++; scnt++;
    now=System.currentTimeMillis();
    r=rand.nextInt(6); r++;    
    loc=lm.getLastKnownLocation(best);    

    if(loc!=null) { 
        lat=loc.getLatitude();
        lng=loc.getLongitude(); 
    }    

    Thread.sleep(100); 
    handler.sendMessage(handler.obtainMessage());
} catch (InterruptedException e) {   
    Toast.makeText(this, "Error="+e.toString(), Toast.LENGTH_LONG).show();
}

Generally git pull is enough, but I'm not sure what layout you have chosen (or has github chosen for you).

People have already answered pretty nicely for the scenario where you need bigrams or trigrams but if you need everygram for the sentence in that case you can use nltk.util.everygrams

>>> from nltk.util import everygrams

>>> message = "who let the dogs out"

>>> msg_split = message.split()

>>> list(everygrams(msg_split))
[('who',), ('let',), ('the',), ('dogs',), ('out',), ('who', 'let'), ('let', 'the'), ('the', 'dogs'), ('dogs', 'out'), ('who', 'let', 'the'), ('let', 'the', 'dogs'), ('the', 'dogs', 'out'), ('who', 'let', 'the', 'dogs'), ('let', 'the', 'dogs', 'out'), ('who', 'let', 'the', 'dogs', 'out')]

Incase you have a limit like in case of trigrams where the max length should be 3 then you can use max_len param to specify it.

>>> list(everygrams(msg_split, max_len=2))
[('who',), ('let',), ('the',), ('dogs',), ('out',), ('who', 'let'), ('let', 'the'), ('the', 'dogs'), ('dogs', 'out')]

You can just modify the max_len param to achieve whatever gram i.e four gram, five gram, six or even hundred gram.

The previous mentioned solutions can be modified to implement the above mentioned solution but this solution is much straight forward than that.

For further reading click here

And when you just need a specific gram like bigram or trigram etc you can use the nltk.util.ngrams as mentioned in M.A.Hassan's answer.

$(window).scroll(function () {

        var ControlDivTop = $('#cs_controlDivFix');

        $(window).scroll(function () {
            if ($(this).scrollTop() > 50) {
               ControlDivTop.stop().animate({ 'top': ($(this).scrollTop() - 62) + "px" }, 600);
            } else {
              ControlDivTop.stop().animate({ 'top': ($(this).scrollTop()) + "px" },600);
            }
        });
    });

I had this same issue, and running script in robomongo (Robo 3T 1.1.1) also doesn't allow to copy values and there was no export option either. The best way I could achieve this is to use mongoexport, if mongodb is installed on your local, you can use mongoexport to connect to database on any server and extract data

To connect to Data on remote server, and csv output file, run the following mongoexport in your command line

mongoexport --host HOSTNAME --port PORT --username USERNAME --password "PASSWORD" --collection COLLECTION_NAME --db DATABASE_NAME --out OUTPUTFILE.csv --type=csv --fieldFile fields.txt

fieldFile: helps to extract the desired columns, ex: contents of fields.txt can be just:

userId

to only extract values of the column 'userId'

Data on remote server, json output file:

mongoexport --host HOST_NAME --port PORT --username USERNAME --password "PASSWORD" --collection COLECTION_NAME --db DATABASE_NAME --out OUTPUT.json

this extracts all fields into the json file

data on localhost (mongodb should be running on localhost)

mongoexport --db DATABASE_NAME --collection COLLECTION --out OUTPUT.json

Reference: https://docs.mongodb.com/manual/reference/program/mongoexport/#use

FWIW,

Poor mans security folder (to protect a public shared folder from little prying eyes ;) )

mkdir -p {0..9}/{0..9}/{0..9}/{0..9}

Now you can put your files in a pin numbered folder. Not exactly waterproof, but it's a barrier for the youngest.

To answer the question first we need to take a look at the purpose of a dictionary and underlying technology.

Dictionary is the list of KeyValuePair<Tkey, Tvalue> where each value is represented by its unique key. Let's say we have a list of your favorite foods. Each value (food name) is represented by its unique key (a position = how much you like this food).

Example code:

Dictionary<int, string> myDietFavorites = new Dictionary<int, string>()
{
    { 1, "Burger"},
    { 2, "Fries"},
    { 3, "Donuts"}
};

Let's say you want to stay healthy, you've changed your mind and you want to replace your favorite "Burger" with salad. Your list is still a list of your favorites, you won't change the nature of the list. Your favorite will remain number one on the list, only it's value will change. This is when you call this:

/*your key stays 1, you only replace the value assigned to this key
  you alter existing record in your dictionary*/
myDietFavorites[1] = "Salad";

But don't forget you're the programmer, and from now on you finishes your sentences with ; you refuse to use emojis because they would throw compilation error and all list of favorites is 0 index based.

Your diet changed too! So you alter your list again:

/*you don't want to replace Salad, you want to add this new fancy 0
  position to your list. It wasn't there before so you can either define it*/
myDietFavorites[0] = "Pizza";

/*or Add it*/
myDietFavorites.Add(0, "Pizza");

There are two possibilities with defining, you either want to give a new definition for something not existent before or you want to change definition which already exists.

Add method allows you to add a record but only under one condition: key for this definition may not exist in your dictionary.

Now we are going to look under the hood. When you are making a dictionary your compiler make a reservation for the bucket (spaces in memory to store your records). Bucket don't store keys in the way you define them. Each key is hashed before going to the bucket (defined by Microsoft), worth mention that value part stays unchanged.

I'll use the CRC32 hashing algorithm to simplify my example. When you defining:

myDietFavorites[0] = "Pizza";

What is going to the bucket is db2dc565 "Pizza" (simplified).

When you alter the value in with:

myDietFavorites[0] = "Spaghetti";

You hash your 0 which is again db2dc565 then you look up this value in your bucket to find if it's there. If it's there you simply rewrite the value assigned to the key. If it's not there you'll place your value in the bucket.

When you calling Add function on your dictionary like:

myDietFavorite.Add(0, "Chocolate");

You hash your 0 to compare it's value to ones in the bucket. You may place it in the bucket only if it's not there.

It's crucial to know how it works especially if you work with dictionaries of string or char type of key. It's case sensitive because of undergoing hashing. So for example "name" != "Name". Let's use our CRC32 to depict this.

Value for "name" is: e04112b1 Value for "Name" is: 1107fb5b

Dang this is hard. Here is what I did to reject/delete/replace my ios build before it was released. The app was approved how ever I found found a bug I wanted to fix before releasing

1. I set release to "manual" and saved
2. I tried to create and app release
3. got an error message something like "you can only have one release at a time"
4. where the save button was there was not an option to cancel release
5. the version of the app is not marked "developer rejected" with a red dot

To replace the bad build I did the following

1. if you click on the "+ version or platform" to create a new version you will not be be able to create a new iOS version
2. you need to upload a new build
3. in your rejected app, select the new build
4. save
5. submit for review

If you use Wordpress you can just use the wordpress build in function with the video id provided wp_get_attachment_metadata($videoID):

wp_get_attachment_metadata($videoID);

helped me a lot. thats why i'm posting it, although its just for wordpress users.

If you want to upload videos programatically, check the YouTube Data API for PHP

Try this:

foreach (Item item in myItemsList)
{
  if (SkipCondition) continue;
  // More stuff here
}

What is a CSS map file?

It is a JSON format file that links the CSS file to its source files, normally, files written in preprocessors (i.e., Less, Sass, Stylus, etc.), this is in order do a live debug to the source files from the web browser.

What is CSS preprocessor? Examples: Sass, Less, Stylus

It is a CSS generator tool that uses programming power to generate CSS robustly and quickly.

This is another trick.

In main 'Makefile' define SRCDIR for each source dir and include 'makef.mk' for each value of SRCDIR. In each source dir put file 'files.mk' with list of source files and compile options for some of them. In main 'Makefile' one can define compile options and exclude files for each value of SRCDIR.

You templatize your class based on an 'unsigned int'.

Example:

template <unsigned int N>
class MyArray
{
    public:
    private:
        double    data[N]; // Use N as the size of the array
};

int main()
{
    MyArray<2>     a1;
    MyArray<2>     a2;

    MyArray<4>     b1;

    a1 = a2;  // OK The arrays are the same size.
    a1 = b1;  // FAIL because the size of the array is part of the
              //      template and thus the type, a1 and b1 are different types.
              //      Thus this is a COMPILE time failure.
 }

Simple Solution. No Jquery

<img id="output" src="" width="100" height="100">_x000D_
_x000D_
<input name="photo" type="file" accept="image/*" onchange="document.getElementById('output').src = window.URL.createObjectURL(this.files[0])">

If your UIBarButtonItem is already allocated like in a storyboard. (printBtn)

    let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
    btn.setImage(UIImage(named: Constants.ImageName.print)?.withRenderingMode(.alwaysTemplate), for: .normal)
    btn.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handlePrintPress(tapGesture:))))
    printBtn.customView = btn

1) Instead of PreparedStatement use Statement

2) After executing query in ResultSet, extract values with the help of rs.getString() as :

Statement st=cn.createStatement();
ResultSet rs=st.executeQuery(sql);
while(rs.next())
{
    rs.getString(1); //or rs.getString("column name");
}

You don't need to do it one at a time. Just do a test for any that are not alpha-numeric. If one is found, the validation fails.

function validateCode(){
    var TCode = document.getElementById('TCode').value;
    if( /[^a-zA-Z0-9]/.test( TCode ) ) {
       alert('Input is not alphanumeric');
       return false;
    }
    return true;     
 }

If there's at least one match of a non alpha numeric, it will return false.

Try this :

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
  $(document).ready(function () {
            var simpleText = "hello_world";
            var finalSplitText = simpleText.split("_");
            var splitText = finalSplitText[0];
            $("#target").text(splitText);
        });
</script>

<body>
<a id="target" href = test.html></a>
</body>
</html>

BufferedWriter out = null;

try {
    FileWriter fstream = new FileWriter("out.txt", true); //true tells to append data.
    out = new BufferedWriter(fstream);
    out.write("\nsue");
}

catch (IOException e) {
    System.err.println("Error: " + e.getMessage());
}

finally {
    if(out != null) {
        out.close();
    }
}

To use getSingleResult on a TypedQuery you can use

query.setFirstResult(0);
query.setMaxResults(1);
result = query.getSingleResult();

The API Demos in the Android SDK have an example that does just that.

It's under DIALOG_TEXT_ENTRY. They have a layout, inflate it with a LayoutInflater, and use that as the View.

EDIT: What I had linked to in my original answer is stale. Here is a mirror.

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.

O(1) means Random Access. In any Random Access Memory, the time taken to access any element at any location is the same. Here time can be any integer, but the only thing to remember is time taken to retrieve the element at (n-1)th or nth location will be same(ie constant).

Whereas O(n) is dependent on the size of n.

First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function

function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
    $databaseConnectionQuery =  mysqli_connect($serverName, $userName, $password, $databaseName);
    if($databaseConnectionQuery === false)
    {
        die("ERROR: Could not connect. " . mysqli_connect_error());
        return false;
    }

    $resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
    $fetchFields = mysqli_fetch_fields($resultQuery);
    $fetchValues = mysqli_fetch_fields($resultQuery);

    if (mysqli_num_rows($resultQuery) > 0) 
    {           

        echo "<table class='table'>";
        echo "<tr>";
        foreach ($fetchFields as $fetchedField)
         {          
            echo "<td>";
            echo "<b>" . $fetchedField->name . "<b></a>";
            echo "</td>";
        }       
        echo "</tr>";
        while($totalRows = mysqli_fetch_array($resultQuery)) 
        {           
            echo "<tr>";                                
            for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
            {           
                echo "<td>";
                echo $totalRows[$eachRecord];
                echo "</td>";               
            }
            echo "<td><a href=''><button>Edit</button></a></td>";
            echo "<td><a href=''><button>Delete</button></a></td>";
            echo "</tr>";           
        } 
        echo "</table>";        

    } 
    else
    {
      echo "No Records Found in";
    }
}

All set now Pass the arguments as For Example

$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;

Here

localhost indicates Name of the host,

root indicates the username for database

root@123 indicates the password for the database

$queryStatment for generating Query

hope it helps
