Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.

myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";

One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.

Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?

This should work:

myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;

Swift version of awolf's answer, which worked for me:

public extension UIImage {
    func croppedImage(inRect rect: CGRect) -> UIImage {
        let rad: (Double) -> CGFloat = { deg in
            return CGFloat(deg / 180.0 * .pi)
        }
        var rectTransform: CGAffineTransform
        switch imageOrientation {
        case .left:
            let rotation = CGAffineTransform(rotationAngle: rad(90))
            rectTransform = rotation.translatedBy(x: 0, y: -size.height)
        case .right:
            let rotation = CGAffineTransform(rotationAngle: rad(-90))
            rectTransform = rotation.translatedBy(x: -size.width, y: 0)
        case .down:
            let rotation = CGAffineTransform(rotationAngle: rad(-180))
            rectTransform = rotation.translatedBy(x: -size.width, y: -size.height)
        default:
            rectTransform = .identity
        }
        rectTransform = rectTransform.scaledBy(x: scale, y: scale)
        let transformedRect = rect.applying(rectTransform)
        let imageRef = cgImage!.cropping(to: transformedRect)!
        let result = UIImage(cgImage: imageRef, scale: scale, orientation: imageOrientation)
        return result
    }
}

you can try below code

1- model or view model

public class UploadImage 
{
  public string ImageFile { get; set; }
  public string ImageName { get; set; }
  public string ImageDescription { get; set; }

        var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "images", ImageFile.FileName);
        using (System.IO.Stream stream = new FileStream(path, FileMode.Create))
         {
            await ImageFile.CopyToAsync(stream);
         }
          model.ImageFile = filename;
         _context.Add(model);
         _context.SaveChanges();
         }        

      return RedirectToAction("Index","Home");   
    }

Don't know much VB.NET syntax but here's and idea

Dim source As New Bitmap("C:\image.png") 
Dim target As New Bitmap(size.Width, size.Height, PixelFormat.Format24bppRgb)

Using graphics As Graphics = Graphics.FromImage(target)
    graphics.DrawImage(source, new Size(48, 48)) 
End Using

CodeProject articles discussing and sharing source code for scaling images:

• Two Pass Scaling using Filters
• Matrix Transformation of Images in C#, using .NET GDI+
• Resizing a Photographic image with GDI+ for .NET
• Fast Dyadic Image Scaling with Haar Transform

AFAIK, the only way to do this is with <canvas/>...

DEMO V2: http://jsfiddle.net/xLF38/818/

Note, this will only work with images on the same domain and in browsers that support HTML5 canvas:

function getAverageRGB(imgEl) {

    var blockSize = 5, // only visit every 5 pixels
        defaultRGB = {r:0,g:0,b:0}, // for non-supporting envs
        canvas = document.createElement('canvas'),
        context = canvas.getContext && canvas.getContext('2d'),
        data, width, height,
        i = -4,
        length,
        rgb = {r:0,g:0,b:0},
        count = 0;

    if (!context) {
        return defaultRGB;
    }

    height = canvas.height = imgEl.naturalHeight || imgEl.offsetHeight || imgEl.height;
    width = canvas.width = imgEl.naturalWidth || imgEl.offsetWidth || imgEl.width;

    context.drawImage(imgEl, 0, 0);

    try {
        data = context.getImageData(0, 0, width, height);
    } catch(e) {
        /* security error, img on diff domain */
        return defaultRGB;
    }

    length = data.data.length;

    while ( (i += blockSize * 4) < length ) {
        ++count;
        rgb.r += data.data[i];
        rgb.g += data.data[i+1];
        rgb.b += data.data[i+2];
    }

    // ~~ used to floor values
    rgb.r = ~~(rgb.r/count);
    rgb.g = ~~(rgb.g/count);
    rgb.b = ~~(rgb.b/count);

    return rgb;

}

Create a BufferedImage from file and make it TYPE_INT_RGB

import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class Main{
    public static void main(String args[]){
        try{
            BufferedImage img = new BufferedImage( 
                500, 500, BufferedImage.TYPE_INT_RGB );
            File f = new File("MyFile.png");
            int r = 5;
            int g = 25; 
            int b = 255;
            int col = (r << 16) | (g << 8) | b;
            for(int x = 0; x < 500; x++){
                for(int y = 20; y < 300; y++){
                    img.setRGB(x, y, col);
                }
            }
            ImageIO.write(img, "PNG", f); 
        }
        catch(Exception e){ 
            e.printStackTrace();
        }
    }
}

This paints a big blue streak across the top.

If you want it ARGB, do it like this:

    try{
        BufferedImage img = new BufferedImage( 
            500, 500, BufferedImage.TYPE_INT_ARGB );
        File f = new File("MyFile.png");
        int r = 255;
        int g = 10;
        int b = 57;
        int alpha = 255;
        int col = (alpha << 24) | (r << 16) | (g << 8) | b;
        for(int x = 0; x < 500; x++){
            for(int y = 20; y < 30; y++){
                img.setRGB(x, y, col);
            }
        }
        ImageIO.write(img, "PNG", f);
    }
    catch(Exception e){
        e.printStackTrace();
    }

Open up MyFile.png, it has a red streak across the top.

Have a look at qtlcharts. It allows you to create interactive correlation matrices:

library(qtlcharts)
data(iris)
iris$Species <- NULL
iplotCorr(iris, reorder=TRUE)

It's more impressive when you correlate more variables, like in the package's vignette:

Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:

// Can pass browser type 

if brower.lower() == 'chrome':
    driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
    ch_Options = Options()
    ch_Options.add_argument('--headless')
    ch_Options.add_argument("--disable-gpu")
    driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
    ff_option = FFOption()
    ff_option.add_argument('--headless')
    ff_option.add_argument("--disable-gpu")
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
    driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
    raise Exception('Invalid Browser Type')

You may also need the following directive to be set before the first "sub_filter" for backend-servers with data compression:

proxy_set_header Accept-Encoding "";

Otherwise it may not work. For your example it will look like:

location /admin/ {
    proxy_pass http://localhost:8080/;
    proxy_set_header Accept-Encoding "";
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

This is how it can be done using CASE:

DECLARE @myParam INT;
SET @myParam = 1;

SELECT * 
  FROM MyTable
 WHERE 'T' = CASE @myParam
             WHEN 1 THEN 
                CASE WHEN MyColumn IS NULL THEN 'T' END
             WHEN 2 THEN
                CASE WHEN MyColumn IS NOT NULL THEN 'T' END
             WHEN 3 THEN 'T' END;

I found myself in a similar case, wanting to generate display groups of 3 columns each. However, although I was using bootstrap, I was trying to separate these groups into different parent divs. I also wanted to make something generically useful.

I approached it with 2 ng-repeat as below:

<div ng-repeat="items in quotes" ng-if="!($index % 3)">
  <div ng-repeat="quote in quotes" ng-if="$index <= $parent.$index + 2 && $index >= $parent.$index">
                ... some content ...
  </div>
</div>

This makes it very easy to change to a different number of columns, and separated out into several parent divs.

In my case the json file encoding was a problem

I was generating JSON file in vb .net with following: My.Computer.FileSystem.WriteAllText("newComponent.json", json.Trim, False)

And I tried all suggestions in this post but none helped.

Eventually in Notepad++ noticed that the file created was in UTF-8-BOM

Not sure how it picked up that encoding but after I switched the encoding to UTF-8, it resolved with no other changes.

Hope this helps someone.

begin   
   dbms_output.put_line( 'hello' ||chr(13) || chr(10) || 'world' );
end;

function hasClass(ele,cls) {
    return ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}

function removeClass(ele,cls) {
        if (hasClass(ele,cls)) {
            var reg = new RegExp('(\\s|^)'+cls+'(\\s|$)');
            ele.className=ele.className.replace(reg,' ');
        }
    }

You can use lodash:

@Component({
  selector: 'board',
  template: `
<div *ngFor="let i of range">
{{i}}
</div>
`,
  styleUrls: ['./board.component.css']
})
export class AppComponent implements OnInit {
  range = _.range(8);
}

I didn't test code but it should work.

Nutshell version: it will build the project and install it in your local repository.

This gets the file type as from the last character (so avoids the problem with dots in file names)

Function getFileType(fn As String) As String

''get last instance of "." (full stop) in a filename then returns the part of the filename starting at that dot to the end
Dim strIndex As Integer
Dim x As Integer
Dim myChar As String

strIndex = Len(fn)
For x = 1 To Len(fn)

    myChar = Mid(fn, strIndex, 1)

    If myChar = "." Then
        Exit For
    End If

    strIndex = strIndex - 1

Next x

getFileType = UCase(Mid(fn, strIndex, Len(fn) - x + 1))

End Function

Another worthy optimization is the c_str ( ) member of the STL string classes, which returns an immutable null terminated string that can be passed around as a LPCTSTR, e. g., to a custom function that expects a LPCTSTR. Although I haven't traced through the destructor to confirm it, I suspect that the string class looks after the memory in which it creates the copy.

Starting with @Ravi's answer, I also applied some validation rules for the NPA (Area) Code.

In particular:

• It should start with a 2 (or higher)
• It cannot have "11" as the second and third digits (N11).

There are a couple other restrictions, including reserved blocks (N9X, 37X, 96X) and 555, but I left those out, particularly because the reserved blocks may see future use, and 555 is useful for testing.

This is what I came up with:

^((\+\d{1,2}|1)[\s.-]?)?\(?[2-9](?!11)\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$

Alternately, if you also want to match blank values (if the field isn't required), you can use:

(^((\+\d{1,2}|1)[\s.-]?)?\(?[2-9](?!11)\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$|^$)

My test cases for valid numbers (many from @Francis' answer) are:

18005551234
1 800 555 1234
+1 800 555-1234
+86 800 555 1234
1-800-555-1234
1.800.555.1234
+1.800.555.1234
1 (800) 555-1234
(800)555-1234
(800) 555-1234
(800)5551234
800-555-1234
800.555.1234

My invalid test cases include:

(003) 555-1212     // Area code starts with 0
(103) 555-1212     // Area code starts with 1
(911) 555-1212     // Area code ends with 11
180055512345       // Too many digits
1 800 5555 1234    // Prefix code too long
+1 800 555x1234    // Invalid delimiter
+867 800 555 1234  // Country code too long
1-800-555-1234p    // Invalid character
1 (800)  555-1234  // Too many spaces
800x555x1234       // Invalid delimiter
86 800 555 1212    // Non-NA country code doesn't have +

My regular expression does not include grouping to extract the digit groups, but it can be modified to include those.

You have two ways:

First go to the particular path of Android SDK:

1) Open your command prompt and traverse to the platform-tools directory through it such as

$ cd Frameworks\Android-Sdk\platform-tools

2) Run your adb commands now such as to know that your adb is working properly :

$ adb devices OR adb logcat OR simply adb

Second way is :

1) Right click on your My Computer.

2) Open Environment variables.

3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).

4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.

5) Restart your computer once.

6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.

Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"

Since nobody mentioned it, MATLAB also has the metaclass function, which returns an object with various bits of information about the passed-in entity. These meta.class objects can be useful for tests of inheritance (via common comparison operators).

For example:

>> metaclass(magic(1))

ans = 

  class with properties:

                     Name: 'double'
              Description: ''
      DetailedDescription: ''
                   Hidden: 0
                   Sealed: 0
                 Abstract: 0
              Enumeration: 0
          ConstructOnLoad: 0
         HandleCompatible: 0
          InferiorClasses: {0×1 cell}
        ContainingPackage: [0×0 meta.package]
     RestrictsSubclassing: 0
             PropertyList: [0×1 meta.property]
               MethodList: [272×1 meta.method]
                EventList: [0×1 meta.event]
    EnumerationMemberList: [0×1 meta.EnumeratedValue]
           SuperclassList: [0×1 meta.class]

>> ?containers.Map <= ?handle

ans =

  logical

   1

We can see that class(someObj) is equivalent to the Name field of the result of metaclass(someObj).

You are looking for strongly typed enumerations, a feature available in the C++11 standard. It turns enumerations into classes with scope values.

Using your own code example, it is:

  enum class Days {Saturday, Sunday, Tuesday,Wednesday, Thursday, Friday};
  Days day = Days::Saturday;

  if (day == Days::Saturday)  {
    cout << " Today is Saturday !" << endl;
  }
  //int day2 = Days::Sunday; // Error! invalid

Using :: as accessors to enumerations will fail if targeting a C++ standard prior C++11. But some old compilers doesn't supported it, as well some IDEs just override this option, and set a old C++ std.

If you are using GCC, enable C+11 with -std=c++11 or -std=gnu11 .

Be happy!

I met the same problem and I resolved it by setting CopyLocal to true for the following libs:

System.Web.Http.dll
System.Web.Http.WebHost.dll
System.Net.Http.Formatting.dll

I must to add that I use MVC4 and NET 4

Workaround I ended up using to avoid all the complexity:

var outputFile = Path.GetTempFileName();
info = new System.Diagnostics.ProcessStartInfo("TheProgram.exe", String.Join(" ", args) + " > " + outputFile + " 2>&1");
info.CreateNoWindow = true;
info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
info.UseShellExecute = false;
System.Diagnostics.Process p = System.Diagnostics.Process.Start(info);
p.WaitForExit();
Console.WriteLine(File.ReadAllText(outputFile)); //need the StandardOutput contents

So I create a temp file, redirect both the output and error to it by using > outputfile > 2>&1 and then just read the file after the process has finished.

The other solutions are fine for scenarios where you want to do other stuff with the output, but for simple stuff this avoids a lot of complexity.

I have just found a PHP function "strip_tags()" and its working in my case.

I tried to convert the following HTML :

<p><span style="font-family: 'Verdana','sans-serif'; color: black; font-size: 7.5pt;">&nbsp;</span>Many  practitioners are optimistic that the eyeglass and contact lens  industry will recover from the recent economic storm.

After applying strip_tags() function, I have got the following output :

 Many  practitioners are optimistic that the eyeglass and contact lens  industry will recover from the recent economic storm. Did your practice  feel its affects?  Statistics show revenue notably declined in 2008 and  2009.

"cat".toCharArray()

But if you need strings

"cat".split("")

Edit: which will return an empty first value.

Think of it as the difference between a requirement and a suggestion. For the select element, the user is required to select one of the options you've given. For the datalist element, it is suggested that the user select one of the options you've given, but he can actually enter anything he wants in the input.

Edit 1: So which one you use depends upon your requirements. If the user must enter one of your choices, use the select element. If the use can enter whatever, use the datalist element.

Edit 2: Found this tidbit in the HTML Living Standard: "Each option element that is a descendant of the datalist element...represents a suggestion."

Disclamer

This is just some additional information that might help anyone. I want to make it abundantly clear that what I am describing here is possibly:

• A. not 100% correct and
• B. not safe in terms of network security.

I am not a DBA, but every time I find myself setting up a SQL Server (Express or Full) for testing or what not I run into the connectivity issue. The solution I am describing is more for the person who is just trying to get their job done - consult someone who is knowledgeable in this field when setting up a production server.

For SQL Server 2008 R2 this is what I end up doing:

1. Make sure everything is squared away like in this tutorial which is the same tutorial posted above as a solution by "Dani" as the selected answer to this question.
2. Check and/or set, your firewall settings for the computer that is hosting the SQL Server. If you are using a Windows Server 2008 R2 then use the Server Manager, go to Configuration and then look at "Windows Firewall with Advanced Security". If you are using Windows 7 then go to Control Panel and search for "Firewall" click on "Allow a program through Windows Firewall".
   • Create an inbound rule for port TCP 1433 - allow the connection
   • Create an outbound rule for port TCP 1433 - allow the connection
3. When you are finished with the firewall settings you are going to want to check one more thing. Open up the "SQL Server Configuration Manager" locate: SQL Server Network Configuration - Protocols for SQLEXPRESS (or equivalent) - TCP/IP
   • Double click on TCP/IP
   • Click on the IP Addresses tab
   • Under IP1 set the TCP Port to 1433 if it hasn't been already
   • Under IP All set the TCP Port to 1433 if it hasn't been already
4. Restart SQL Server and SQL Browser (do both just to be on the safe side)

Usually after I do what I mentioned above I don't have a problem anymore. Here is a screenshot of what to look for - for that last step:

Again, if someone with more information about this topic sees a red flag please correct me.

Also, you can try (for Windows 10 Pro) Run Powershell as administrator and type ssh-keygen -t rsa -b 4096 -C "[email protected]"

I believe the kernel raises SIGBUS when an application exhibits data misalignment on the data bus. I think that since most[?] modern compilers for most processors pad / align the data for the programmers, the alignment troubles of yore (at least) mitigated, and hence one does not see SIGBUS too often these days (AFAIK).

Most likely the path you are trying to access does not exist. It seems you are trying to save to a relative location and you do not have an file extension in that string. If you need to use relative paths you can parse the path from ActiveWorkbook.FullName

EDIT: Better syntax would also be

ActiveWorkbook.SaveAs Filename:=myFileName, FileFormat:=xlWorkbookNormal

Here is my version, which provides writelines() and fileno(), too:

class FlushFile(object):
    def __init__(self, fd):
        self.fd = fd

    def write(self, x):
        ret = self.fd.write(x)
        self.fd.flush()
        return ret

    def writelines(self, lines):
        ret = self.writelines(lines)
        self.fd.flush()
        return ret

    def flush(self):
        return self.fd.flush

    def close(self):
        return self.fd.close()

    def fileno(self):
        return self.fd.fileno()

As c-smile mentioned: Just need to remove the apostrophes in the url():

<div style="background-image: url(http://i54.tinypic.com/4zuxif.jpg)"></div>

There's no much point in doing that, because View should be generating html, not the controller. But anyways, you could use Controller.Content method, which gives you ability to specify result html, also content-type and encoding

public ActionResult Index()
{
    return Content("<html></html>");
}

Or you could use the trick built in asp.net-mvc framework - make the action return string directly. It will deliver string contents into users's browser.

public string Index()
{
    return "<html></html>";
}

In fact, for any action result other than ActionResult, framework tries to serialize it into string and write to response.

What about data binding?

@JvmStatic
@BindingAdapter("textHtml")
fun setHtml(textView: TextView, resource: String) {
    val html: Spanned = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Html.fromHtml(resource, Html.FROM_HTML_MODE_COMPACT)
    } else {
        Html.fromHtml(resource)
    }

    textView.movementMethod = LinkMovementMethod.getInstance()
    textView.text = html
}

strings.xml

<string name="text_with_link">&lt;a href=%2$s>%1$s&lt;/a> </string>

in your layout.xml

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:textHtml="@{@string/text_with_link(model.title, model.url)}"
            tools:text="Some text" />

Where title and link in xml is a simple String

Also you can pass multiple arguments to data binding adapter

@JvmStatic
@BindingAdapter(value = ["textLink", "link"], requireAll = true)
fun setHtml(textView: TextView, textLink: String?, link: String?) {
    val resource = String.format(textView.context.getString(R.string.text_with_link, textLink, link))

    val html: Spanned = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Html.fromHtml(resource, Html.FROM_HTML_MODE_COMPACT)
    } else {
        Html.fromHtml(resource)
    }

    textView.movementMethod = LinkMovementMethod.getInstance()
    textView.text = html
}

and in .xml pass arguments separately

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:link="@{model.url}"
            app:textLink="@{model.title}"
            tools:text="Some text" />

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

You can use numpy.tile, e.g. :

v = 7
rows = 3
cols = 5
a = numpy.tile(v, (rows,cols))
a
Out[1]: 
array([[7, 7, 7, 7, 7],
       [7, 7, 7, 7, 7],
       [7, 7, 7, 7, 7]])

Although tile is meant to 'tile' an array (instead of a scalar, as in this case), it will do the job, creating pre-filled arrays of any size and dimension.

Simplest is actually just Age.Max(), you don't need any more code.

From what I saw in Express 4.0 this works for me. This is example of authentication required middleware.

function apiDemandLoggedIn(req, res, next) {

    // if user is authenticated in the session, carry on
    console.log('isAuth', req.isAuthenticated(), req.user);
    if (req.isAuthenticated())
        return next();

    // If not return 401 response which means unauthroized.
    var err = new Error();
    err.status = 401;
    next(err);
}

extending de Almeida's answer I am editing code little bit here. since previous code was hiding gps location icon I did following way which worked better.

I found an .ipa file that I wanted using iTunes and copied it over to my desktop.

After that I changed the extension to .zip and extracted it.

Next I found the Payload folder and moved the application inside to my desktop.

Finally I moved that application to my iPhone simulators applications folder found at:

• HD
• > Applications
• > Xcode.app (right click - Show Package Contents)
• > Contents
• > Developer
• > Platforms
• > iPhoneSimulator.platform
• > SDKs

• > Applications

Hope this helps! (Note: Some apps crash more often than others.)

For those using Laravel 5 you need to set the namespace for the controller within the sub-directory (Laravel 5 is still in development and changes are happening daily)

To get a folder structure like:

Http
----Controllers
    ----Admin
            PostsController.php
    PostsController.php

namespace Admin\PostsController.php file like so:

<?php namespace App\Http\Controller\Admin;

use App\Http\Controllers\Controller;

class PostsController extends Controller {

    //business logic here
}

Then your route for this is:

$router->get('/', 'Admin\PostsController@index');

And lastly, don't for get to do either composer or artisan dump

composer dump-autoload

or

php artisan dump

changing templateUrl: '' to template: '' fixed it

trick that is working here is the id that I have assigned to ImageView "imgView.setId(v)" and after that applying onClickListener to that I am again fetching the id of the view....I have also commented inside the code so that its easy to understand, I hope this may be very useful... Happy Coding... :)

You should override toString() method in your Dog class. which will be called when you use this object in sysout.

If you want to find one element or None use default in next, it won't raise StopIteration if the item was not found in the list:

first_or_default = next((x for x in lst if ...), None)

Seriously, just don't use jQuery for this. disabled is a boolean property of form elements that works perfectly in every major browser since 1997, and there is no possible way it could be simpler or more intuitive to change whether or not a form element is disabled.

The simplest way of getting a reference to the checkbox would be to give it an id. Here's my suggested HTML:

<input type="hidden" name="chk0" value="">
<input type="checkbox" name="chk0" id="chk0_checkbox" value="true" disabled>

And the line of JavaScript to make the check box enabled:

document.getElementById("chk0_checkbox").disabled = false;

If you prefer, you can instead use jQuery to get hold of the checkbox:

$("#chk0_checkbox")[0].disabled = false;

<div class="crop">longlong longlong longlong longlong longlong longlong </div>?

This is one possible approach i can think of

.crop {width:100px;overflow:hidden;height:50px;line-height:50px;}?

This way the long text will still wrap but will not be visible due to overflow set, and by setting line-height same as height we are making sure only one line will ever be displayed.

See demo here and nice overflow property description with interactive examples.

Requirement: Function to find a string in an array.
This is a slight simplification of DevSolar's solution in that it uses the arguments passed rather than copying them.

myarray=('foobar' 'foxbat')

function isInArray() {
  local item=$1
  shift
  for one in $@; do
    if [ $one = $item ]; then
      return 0   # found
    fi
  done
  return 1       # not found
}

var='foobar'
if isInArray $var ${myarray[@]}; then
  echo "$var found in array"
else
  echo "$var not found in array"
fi 

Python:

driver.get(url)
content=driver.page_source
if content.find("text_to_search"): 
    print("text is present in the webpage")

Download the html page and use find()

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

   Private Sub FileMenu_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) handles FileMenu.Click

    Form1.MdiParent = Me
    Form1.Dock = DockStyle.Fill
    Form1.Show()
End Sub

You can use .attr() as a part of however you plan to toggle it:

$("button").attr("aria-expanded","true");

The functionality is indeed similar (apart from the calling semantics, where call-template requires a name attribute and a corresponding names template).

However, the parser will not execute the same way.

From MSDN:

Unlike <xsl:apply-templates>, <xsl:call-template> does not change the current node or the current node-list.

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

You are writing to the file prior to closing your filestream:

using(FileStream fs=new FileStream(path,FileMode.OpenOrCreate))
using (StreamWriter str=new StreamWriter(fs))
{
   str.BaseStream.Seek(0,SeekOrigin.End); 
   str.Write("mytext.txt.........................");
   str.WriteLine(DateTime.Now.ToLongTimeString()+" "+DateTime.Now.ToLongDateString());
   string addtext="this line is added"+Environment.NewLine;

   str.Flush();

}

File.AppendAllText(path,addtext);  //Exception occurrs ??????????
string readtext=File.ReadAllText(path);
Console.WriteLine(readtext);

The above code should work, using the methods you are currently using. You should also look into the using statement and wrap your streams in a using block.

Take a look at the ListBox control to allow multi-select.

<asp:ListBox runat="server" ID="lblMultiSelect" SelectionMode="multiple">
            <asp:ListItem Text="opt1" Value="opt1" />
            <asp:ListItem Text="opt2" Value="opt2" />
            <asp:ListItem Text="opt3" Value="opt3" />
</asp:ListBox> 

in the code behind

foreach(ListItem listItem in lblMultiSelect.Items)
    {
       if (listItem.Selected)
       {
          var val = listItem.Value;
          var txt = listItem.Text; 
       }
    }

I had this problem when trying to consume a value returned from a stored procedure.

console.log(result[0]);

would output "[ RowDataPacket { datetime: '2019-11-15 16:37:05' } ]".

I found that

console.log(results[0][0].datetime);

Gave me the value I wanted.

Add:

  <%= csrf_meta_tag %>  and 
  <%= javascript_include_tag :defaults %>  to layouts

Use these link_to tags

 link_to 'Sign out', destroy_user_session_path, :method => :delete

  or

 link_to 'Sign out', '/users/sign_out', :method => :delete

In routes add:

  devise_for :users do
    get '/users/sign_out' => 'devise/sessions#destroy'
  end

1)What is the difference between both the way of creating class objects.

First one is a pointer to a constructed object in heap (by new). Second one is an object that implicitly constructed. (Default constructor)

2)If i am creating object like Example example; how to use that in an singleton class.

It depends on your goals, easiest is put it as a member in class simply.

A sample of a singleton class which has an object from Example class:

class Sample
{

    Example example;

public:

    static inline Sample *getInstance()
    {
        if (!uniqeInstance)
        {
            uniqeInstance = new Sample;
        }
        return uniqeInstance;
    }
private:
    Sample();
    virtual ~Sample();
    Sample(const Sample&);
    Sample &operator=(const Sample &);
    static Sample *uniqeInstance;
};

I would use the property display: table-cell

Here is the link

I have got the solution for my query:

i have done something like this:

cell.innerHTML="<img height=40 width=40 alt='' src='<%=request.getContextPath()%>/writeImage.htm?' onerror='onImgError(this);' onLoad='setDefaultImage(this);'>"

function setDefaultImage(source){
        var badImg = new Image();
        badImg.src = "video.png";
        var cpyImg = new Image();
        cpyImg.src = source.src;

        if(!cpyImg.width)
        {
            source.src = badImg.src;
        }

    }


    function onImgError(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
    } 

This way it's working in all browsers.

If you need to change the value of another field, you can use this:

<input type="hidden" id="mainvalue" name="mainvalue" value="0">
<select onChange="document.getElementById('mainvalue').value = this.value;">
<option value="0">option 1</option>
<option value="1">option 2</option>
</select>

You're passing a type as an argument, not an object. You need to do characterSelection(screen, test); where test is of type SelectionneNonSelectionne.

if you are using Spring version of 3.1 or newer you can specify "produces" in @RequestMapping annotation. Example below works for me out of box. No need of register converter or anything else if you have web mvc enabled (@EnableWebMvc).

@ResponseBody
@RequestMapping(value = "/photo2", method = RequestMethod.GET, produces = MediaType.IMAGE_JPEG_VALUE)
public byte[] testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
    return IOUtils.toByteArray(in);
}

If you meant just ABC as simple value, answer above is the one that works fine.

If you meant concatenation of values of rows that are not selected by your main query, you will need to use a subquery.

Something like this may work:

SELECT t1.col1, 
t1.col2, 
(SELECT GROUP_CONCAT(col2 SEPARATOR '') FROM  Table1 t2 WHERE t2.col1 != 0) as col3 
FROM Table1 t1
WHERE t1.col1 = 0;

Actual syntax maybe a bit off though

I had to do this to get it to work:

$pair = "$($user):$($pass)"
$encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($Pair))
$headers = @{ Authorization = "Basic $encodedCredentials" }
Invoke-WebRequest -Uri $url -Method Get -Headers $headers -OutFile Config.html

It seems like sometime during the second half of 2018 many php packages such as php-mysql and phpmyadmin were removed or changed. I faced that same problem too. So you'll have to download it from another source or find out the new packages

I"m not sure if its too late, but the problem is that, you cannot set the columns in design mode if you are binding at runtime. So if you are binding at runtime, go ahead and remove the columns from the design mode and do it pragmatically

ex..

     if (dt.Rows.Count > 0)
    {
        dataGridViewProjects.DataSource = dt;
        dataGridViewProjects.Columns["Title"].Width = 300;
        dataGridViewProjects.Columns["ID"].Visible = false;
    }

textBox1.Text = "Line1\r\r\Line2";
Solved the problem.

here is a better answer found through Git docs.

This shows what the heroku remote is:

$ git remote get-url heroku

Found it here: https://git-scm.com/docs/git-remote Also in that document is a set-url, if you need to change it.

Use:

<html>
    <head>
        <title>Reload (Refresh) Page Using Jquery</title>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function () {
                $('#reload').click(function() {
                    window.location.reload();
                });
            });
        </script>
    </head>
    <body>
        <button id="reload" >Reload (Refresh) Page Using</button>
    </body>
</html>

for Google Maps v3, you need to trigger the resize event differently:

google.maps.event.trigger(map, "resize");

See the documentation for the resize event (you'll need to search for the word 'resize'): http://code.google.com/apis/maps/documentation/v3/reference.html#event

Update

This answer has been here a long time, so a little demo might be worthwhile & although it uses jQuery, there's no real need to do so.

$(function() {
  var mapOptions = {
    zoom: 8,
    center: new google.maps.LatLng(-34.397, 150.644)
  };
  var map = new google.maps.Map($("#map-canvas")[0], mapOptions);

  // listen for the window resize event & trigger Google Maps to update too
  $(window).resize(function() {
    // (the 'map' here is the result of the created 'var map = ...' above)
    google.maps.event.trigger(map, "resize");
  });
});

html,
body {
  height: 100%;
}
#map-canvas {
  min-width: 200px;
  width: 50%;
  min-height: 200px;
  height: 80%;
  border: 1px solid blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Google Maps resize demo
<div id="map-canvas"></div>

UPDATE 2018-05-22

With a new renderer release in version 3.32 of Maps JavaScript API the resize event is no longer a part of Map class.

The documentation states

When the map is resized, the map center is fixed

• The full-screen control now preserves center.

• There is no longer any need to trigger the resize event manually.

source: https://developers.google.com/maps/documentation/javascript/new-renderer

google.maps.event.trigger(map, "resize"); doesn't have any effect starting from version 3.32

yet another way (my favorite), starting with C# 6

private readonly int MyVal = 5;

public int MyProp => MyVal;

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties#expression-body-definitions

style="column-width:300px;white-space: normal;"

In Python2, input is evaluated, input() is equivalent to eval(raw_input()). When you enter klj, Python tries to evaluate that name and raises an error because that name is not defined.

Use raw_input to get a string from the user in Python2.

Demo 1: klj is not defined:

>>> input()
klj
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'klj' is not defined

Demo 2: klj is defined:

>>> klj = 'hi'
>>> input()
klj
'hi'

Demo 3: getting a string with raw_input:

>>> raw_input()
klj
'klj'

After endless searching and trying the already supplied answers (adding the PUT,DELETE verbs and remove WEBdav) it just didn't work.

I went to IIS logging settings: > View Log Files. In my case W3SVC4 was the folder with the latest date, opened the folder, looked up the latest log file and saw this entry: GET /Rejected-By-UrlScan ~/MYDOMAIN/API/ApiName/UpdateMETHOD

The Update method was listed with verb GET, weird right? So I Googled for Rejected-By-UrlScan and found this link: UrlScan Broke My Blog.

I went to here: %windir%\system32\inetsrv\urlscan\UrlScan.ini

Basically, the UrlScan blocked PUT and DELETE verbs. I opened this INI file, added the PUT and DELETE to the AllowVerbs and removed them from the DenyVerbs listings. I saved the INI file and it worked! So for me these steps were necessary next to the ExtensionlessUrlHandler hints.

Windows Webserver 2008 R2 (64 bit), IIS 7.5. I'm using this in combination with DotNetNuke (DNN) WebAPI. ASP.Net 4.0 My update method:

[HttpPut]
[DnnAuthorize(StaticRoles = "MyRoleNames")]
public HttpResponseMessage UpdateMETHOD(DTO.MyObject myData)

TruncateString

public static string _TruncateString(string input, int charaterlimit)
{
    int characterLimit = charaterlimit;
    string output = input;

    // Check if the string is longer than the allowed amount
    // otherwise do nothing
    if (output.Length > characterLimit && characterLimit > 0)
    {
        // cut the string down to the maximum number of characters
        output = output.Substring(0, characterLimit);
        // Check if the character right after the truncate point was a space
        // if not, we are in the middle of a word and need to remove the rest of it
        if (input.Substring(output.Length, 1) != " ")
        {
            int LastSpace = output.LastIndexOf(" ");

            // if we found a space then, cut back to that space
            if (LastSpace != -1)
            {
                output = output.Substring(0, LastSpace);
            }
        }
        // Finally, add the "..."
        output += "...";
    }
    return output;
}

No, they're not the same. Aside from the escaping on the client-side that it provides, a prepared statement is compiled on the server-side once, and then can be passed different parameters at each execution. Which means you can do:

$sth = $db->prepare("SELECT * FROM table WHERE foo = ?");
$sth->execute(array(1));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

$sth->execute(array(2));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

They generally will give you a performance improvement, although not noticeable on a small scale. Read more on prepared statements (MySQL version).

Suppose we have a collection like below:

{ 
  "_id":"1234"
  "open":"Yes"
  "things":{
             "paper":1234
             "bottle":"Available"
             "bottle_count":40
            } 
}

We want to know if the bottle field is present or not?

Ans:

db.products.find({"things.bottle":{"$exists":true}})

This can also be caused by using an out-of-date pip with a recent wheel file.

I was very confused, because I was installing numpy-1.10.4+mkl-cp27-cp27m-win_amd64.whl (from here), and it is definitely the correct version for my Python installation (Windows 64-bit Python 2.7.11). I got the "not supported wheel on this platform" error.

Upgrading pip with python -m pip install --upgrade pip solved it.

I have never had any luck with any scrollable content placed inside a stackpanel (anything derived from ScrollableContainer. The stackpanel has an odd layout mechanism that confuses child controls when the measure operation is completed and I found the vertical size ends up infinite, therefore not constrained - so it goes beyond the boundaries of the container and ends up clipped. The scrollbar doesn't show because the control thinks it has all the space in the world when it doesn't.

You should always place scrollable content inside a container that can resolve to a known height during its layout operation at runtime so that the scrollbars size appropriately. The parent container up in the visual tree must be able to resolve to an actual height, and this happens in the grid if you set the height of the RowDefinition o to auto or fixed.

This also happens in Silverlight.

If your class2 looks like this having static members

public class2
{
    static int var = 1;

    public static void myMethod()
    {
      // some code

    }
}

Then you can simply call them like

class2.myMethod();
class2.var = 1;

If you want to access non-static members then you would have to instantiate an object.

class2 object = new class2();
object.myMethod();  // non static method
object.var = 1;     // non static variable

List<String> lsColumns = new List<string>();

if(dt.Rows.Count>0)
{
    var count = dt.Rows[0].Table.Columns.Count;

    for (int i = 0; i < count;i++ )
    {
        lsColumns.Add(Convert.ToString(dt.Rows[0][i]));
    }
}

If you're not against using an external dependency from maven central, I wrote gethostname4j to solve this problem for myself. It just uses JNA to call libc's gethostname function (or gets the ComputerName on Windows) and returns it to you as a string.

https://github.com/mattsheppard/gethostname4j

This is what I implemented without using pipe.

component.html

<div *ngFor="let item of filter(itemsList)">

component.ts

@Component({
....
})
export class YourComponent {
  filter(itemList: yourItemType[]): yourItemType[] {
    let result: yourItemType[] = [];
    //your filter logic here
    ...
    ...
    return result;
  }
}

Try this to get the month in number form:

Month(DateAdd("m", -3, Now))

It will give you 12 for December.

So in your case you would use Month(DateAdd("m", -1, Now)) to just subract one month.

I had the same problem. I am using Phonegap and Jquery mobile, for Adroid devices. To resize properly I had to set a timeout:

$(window).bind('orientationchange',function(e) {
  fixOrientation();
});

$(window).bind('resize',function(e) {
  fixOrientation();
});

function fixOrientation() {

    setTimeout(function() {

        var windowWidth = window.innerWidth;

        $('div[data-role="page"]').width(windowWidth);
        $('div[data-role="header"]').width(windowWidth);
        $('div[data-role="content"]').width(windowWidth-30);
        $('div[data-role="footer"]').width(windowWidth);

    },500);
}

Where are you configuring your authenticated URL pattern(s)? I only see one uri in your code.

Do you have multiple configure(HttpSecurity) methods or just one? It looks like you need all your URIs in the one method.

I have a site which requires authentication to access everything so I want to protect /*. However in order to authenticate I obviously want to not protect /login. I also have static assets I'd like to allow access to (so I can make the login page pretty) and a healthcheck page that shouldn't require auth.

In addition I have a resource, /admin, which requires higher privledges than the rest of the site.

The following is working for me.

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests()
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()
        .antMatchers("/static/**").permitAll()
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .and()
            .formLogin().loginPage("/login").failureUrl("/login?error")
                .usernameParameter("username").passwordParameter("password")
        .and()
            .logout().logoutSuccessUrl("/login?logout")
        .and()
            .exceptionHandling().accessDeniedPage("/403")
        .and()
            .csrf();

}

NOTE: This is a first match wins so you may need to play with the order. For example, I originally had /** first:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()

Which caused the site to continually redirect all requests for /login back to /login. Likewise I had /admin/** last:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")

Which resulted in my unprivledged test user "guest" having access to the admin interface (yikes!)

import numpy as np
import scipy.stats


def mean_confidence_interval(data, confidence=0.95):
    a = 1.0 * np.array(data)
    n = len(a)
    m, se = np.mean(a), scipy.stats.sem(a)
    h = se * scipy.stats.t.ppf((1 + confidence) / 2., n-1)
    return m, m-h, m+h

you can calculate like this way.

The solutions given here actually do not take into account multi-byte Unicode characters ("composed characters"), and could result in invalid Unicode strings.

In fact, the iOS header file which contains the declaration of substringToIndex contains the following comment:

Hint: Use with rangeOfComposedCharacterSequencesForRange: to avoid breaking up composed characters

See how to use rangeOfComposedCharacterSequenceAtIndex: to delete the last character correctly.

I suggest creating an additional connection for the second command, would solve it. Try to combine both queries in one query. Create a subquery for the count.

while (dr3.Read())
{
    dados_historico[4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
}

Why override the same value again and again?

if (dr3.Read())
{
    dados_historico[4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
}

Would be enough.

For anyone trying to get this working using the Sysdeo Eclipse Tomcat plugin, try the following steps (I used Sysdeo Tomcat Plugin 3.3.0, Eclipse Kepler, and Tomcat 7.0.53 to construct these steps):

1. Window --> Preferences --> Expand the Tomcat node in the tree --> JVM Settings
2. Under "Append to JVM Parameters", click the "Add" button.
3. In the "New Tomcat JVM parameter" popup, enter -Djava.util.logging.config.file="{TOMCAT_HOME}\conf\logging.properties", where {TOMCAT_HOME} is the path to your Tomcat directory (example: C:\Tomcat\apache-tomcat-7.0.53\conf\logging.properties). Click OK.
4. Under "Append to JVM Parameters", click the "Add" button again.
5. In the "New Tomcat JVM parameter" popup, enter -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager. Click OK.
6. Click OK in the Preferences window.
7. Make the adjustments to the {TOMCAT_HOME}\conf\logging.properties file as specified in the question above.
8. The next time you start Tomcat in Eclipse, you should see the scanned .jars listed in the Eclipse Console instead of the "Enable debug logging for this logger" message. The information should also be logged in {TOMCAT_HOME}\logs\catalina.yyyy-mm-dd.log.

I have faced same problem and resolved it by using following scenario.

1 ) First we have to determine which jar file's source code we want along with version number. For Example "Spring Core » 4.0.6.RELEASE" 2 ) open https://mvnrepository.com/ and search file with name "Spring Core » 4.0.6.RELEASE". 3 ) Now Maven repository will show the the details of that jar file. 4 ) In that details there is one option "View All" just click on that. 5 ) Then we will navigate to URL "https://repo1.maven.org/maven2/org/springframework/spring-core/4.0.6.RELEASE/".

6) there so many options so select and download "spring-core-4.0.6.RELEASE-sources.jar " in our our system and attach same jar file as a source attachment in eclipse.

Maybe

mysql> show processlist;

Assuming that your objects are all of a similar type you could add a method as a category of their base class that calls the function you're using for your criteria. Then create an NSPredicate object that refers to that method.

In some category define your method that uses your function

@implementation BaseClass (SomeCategory)
- (BOOL)myMethod {
    return someComparisonFunction(self, whatever);
}
@end

Then wherever you'll be filtering:

- (NSArray *)myFilteredObjects {
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"myMethod = TRUE"];
    return [myArray filteredArrayUsingPredicate:pred];
}

Of course, if your function only compares against properties reachable from within your class it may just be easier to convert the function's conditions to a predicate string.

I think that this construct: if exists (select... is specific for MS SQL. In MySQL EXISTS predicate tells you whether the subquery finds any rows and it's used like this: SELECT column1 FROM t1 WHERE EXISTS (SELECT * FROM t2);

You can rewrite the above lines of code like this:

DELIMITER $$

CREATE PROCEDURE `checando`(in nombrecillo varchar(30), in contrilla varchar(30), out resultado int)

BEGIN
    DECLARE count_prim INT;
    DECLARE count_sec INT;

    SELECT COUNT(*) INTO count_prim FROM compas WHERE nombre = nombrecillo AND contrasenia = contrilla;
    SELECT COUNT(*) INTO count_sec FROM FROM compas WHERE nombre = nombrecillo;

    if (count_prim > 0) then
        set resultado = 0;
    elseif (count_sec > 0) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
    SELECT resultado;
END

One method I did with mine, is to "Add to Source Control", and select 'Git'.

What you need to be certain is that the service using the DB is not running.

Experienced same issue, running some Java apps, and none of the above options worked, not even restart.

Run a ps aux kill the main service using the DB.

• kill -9 'PID' of the application
• or if the application runs as a service make sure to run the service stop cmd for your OS.

After that the default way to drop a table will work flawlessly.

In my example were issues with

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0
R> 

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

We use a lot of DLL's (> 100) in our project. These DLL's have dependencies on each other and therefore we chose the setup of dynamic linking. However it has the following disadvantages:

• slow startup (> 10 seconds)
• DLL's had to be versioned, since windows loads modules on uniqueness of names. Own written components would otherwise get the wrong version of the DLL (i.e. the one already loaded instead of its own distributed set)
• optimizer can only optimize within DLL boundaries. For example the optimizer tries to place frequently used data and code next to each other, but this will not work across DLL boundaries

Maybe a better setup was to make everything a static library (and therefore you just have one executable). This works only if no code duplication takes place. A test seems to support this assumption, but i couldn't find an official MSDN quote. So for example make 1 exe with:

• exe uses shared_lib1, shared_lib2
• shared_lib1 use shared_lib2
• shared_lib2

The code and variables of shared_lib2 should be present in the final merged executable only once. Can anyone support this question?

This could be caused by a number of reasons, including the driver you are using.

a) Some drivers do not allow nested statements. Depending if your driver supports JDBC 3.0 you should check the third parameter when creating the Statement object. For instance, I had the same problem with the JayBird driver to Firebird, but the code worked fine with the postgres driver. Then I added the third parameter to the createStatement method call and set it to ResultSet.HOLD_CURSORS_OVER_COMMIT, and the code started working fine for Firebird too.

static void testNestedRS() throws SQLException {

    Connection con =null;
    try {
        // GET A CONNECTION
        con = ConexionDesdeArchivo.obtenerConexion("examen-dest");
        String sql1 = "select * from reportes_clasificacion";

        Statement st1 = con.createStatement(
                ResultSet.TYPE_SCROLL_INSENSITIVE,
                ResultSet.CONCUR_READ_ONLY, 
                ResultSet.HOLD_CURSORS_OVER_COMMIT);
        ResultSet rs1 = null;

        try {
            // EXECUTE THE FIRST QRY
            rs1 = st1.executeQuery(sql1);

            while (rs1.next()) {
                // THIS LINE WILL BE PRINTED JUST ONCE ON
                                    // SOME DRIVERS UNLESS YOU CREATE THE STATEMENT 
                // WITH 3 PARAMETERS USING 
                                    // ResultSet.HOLD_CURSORS_OVER_COMMIT
                System.out.println("ST1 Row #: " + rs1.getRow());

                String sql2 = "select * from reportes";
                Statement st2 = con.createStatement(
                        ResultSet.TYPE_SCROLL_INSENSITIVE,
                        ResultSet.CONCUR_READ_ONLY);

                // EXECUTE THE SECOND QRY.  THIS CLOSES THE FIRST 
                // ResultSet ON SOME DRIVERS WITHOUT USING 
                                    // ResultSet.HOLD_CURSORS_OVER_COMMIT

                st2.executeQuery(sql2);

                st2.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            rs1.close();
            st1.close();
        }

    } catch (SQLException e) {

    } finally {
        con.close();

    }

}

b) There could be a bug in your code. Remember that you cannot reuse the Statement object, once you re-execute a query on the same statement object, all the opened resultsets associated with the statement are closed. Make sure you are not closing the statement.

Turn the String into a char[], replace the letter by index, then convert the array back into a String.

String myName = "domanokz";
char[] myNameChars = myName.toCharArray();
myNameChars[4] = 'x';
myName = String.valueOf(myNameChars);

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

From here what I understand DataFrames are:

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects.

And Series are:

Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.).

Series have a name attribute which can be accessed like so:

 In [27]: s = pd.Series(np.random.randn(5), name='something')

 In [28]: s
 Out[28]: 
 0    0.541
 1   -1.175
 2    0.129
 3    0.043
 4   -0.429
 Name: something, dtype: float64

 In [29]: s.name
 Out[29]: 'something'

EDIT: Based on OP's comments, I think OP was looking for something like:

 >>> df = pd.DataFrame(...)
 >>> df.name = 'df' # making a custom attribute that DataFrame doesn't intrinsically have
 >>> print(df.name)
 'df'

You could only write one where clause.

 SELECT table1.f_id  FROM table1
 INNER JOIN table2
 ON table2.f_id = table1.f_id
 where table1.f_com_id = '430' AND      
 table1.f_status = 'Submitted' AND table2.f_type = 'InProcess'

Try giving your Button in your main.xml a more descriptive name such as:

<Button
                android:id="@+id/buttonXYZ"

(use lowercase in your xml files, at least, the first letter)

And then in your MainActivity class, declare it as:

Button buttonXYZ;

In your onCreate(Bundle savedInstanceState) method, define it as:

buttonXYZ = (Button) findViewById(R.id.buttonXYZ);

Also, move the Buttons/TextViews outside and place them before the .setOnClickListener - it makes the code cleaner.

Username = (EditText)findViewById(R.id.Username);
CompanyID = (EditText)findViewById(R.id.CompanyID);

you can use this command :

CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name
  [create_specification] ...

create_specification:
    [DEFAULT] CHARACTER SET [=] charset_name
    | [DEFAULT] COLLATE [=] collation_name

In my case, I don't have Design or Preview tab.

• Configure the android-sdk path to contains no space character
• Restart Android Studio in Admin mode

I just had a problem where a previously working project stopped working with everything that referenced R being posted as errors because R.java was not being generated.

** * CHECK THE CONSOLE VIEW TOO **

I had (using finder) made a backup of the main icon (not even used) so one of the res folders (hdpi) had

icon.png copy of icon.png

Console indicated that "copy of icon.png" was not a valid file name. No errors were flagged anywhere else - no red X in the res folders....

but replacing the spaces with "_" and it is all back to normal....

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

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

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

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

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

And then:

$ mvn compile
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [compile]
[INFO] ------------------------------------------------------------------------

[INFO] [exec:exec {execution: some-execution}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

Note that you can specify a configuration inside an execution.

1) As explained above the insert and remove operations give good performance (O(1)) in LinkedList compared to ArrayList(O(n)). Hence if there is a requirement of frequent addition and deletion in application then LinkedList is a best choice.

2) Search (get method) operations are fast in Arraylist (O(1)) but not in LinkedList (O(n)) so If there are less add and remove operations and more search operations requirement, ArrayList would be your best bet.

There's the more general but perhaps not as helpful to you Wireshark.

Swift 5 another way. Resistant to interaction with UI

I would like to show a solution that is resistant to user interaction with other UI elements during countdown. In the comments I explained what each line of code means.

 var timeToSet = 0
 var timer: Timer?

 ...

 @IBAction func btnWasPressed(_ sender: UIButton) {

      //Setting the countdown time
      timeLeft = timeToSet
      //Disabling any previous timers.
      timer?.invalidate()
      //Initialization of the Timer with interval every 1 second with the function call.
      timer = Timer(timeInterval: 1.0, target: self, selector: #selector(countDown), userInfo: nil, repeats: true)
      //Adding Timer to the current loop
      RunLoop.current.add(timer!, forMode: .common)

  }

 ...

 @objc func countDown() {

     if timeLeft > 0 {
         print(timeLeft)
         timeLeft -= 1
     } else {
         // Timer stopping
         timer?.invalidate()
     }
 }

Python 3 includes an improved super() which allows use like this:

super().__init__(args)

Using Jquery, simply use this function:

<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
}
</script>

Your print button will look like this:

<button id="print" onclick="printContent('id name of your div');" >Print</button>

Edit: If you DO have form data that you need to keep, clone won't copy that, so you'll just need to grab all the form data and replace it after restore as so:

<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
var enteredtext = $('#text').val();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
$('#text').html(enteredtext);
}
</script>
<textarea id="text"></textarea>

IMHO you need to read many links , resources to make an idea about the difference between Runtime vs Compile time because it is a very complex subject . I have list below some of this pictures/links that I am recommend .

Apart from what it is said above I want to add that sometimes a picture worth 1000 words :

1. the order of this two: first is compile time and then you run A compiled program can be opened and run by a user. When an application is running, it is called runtime : compile time and then runtime1 ;

CLR_diag compile time and then runtime2

 from Wiki  

https://en.wikipedia.org/wiki/Run_time https://en.wikipedia.org/wiki/Run_time_(program_lifecycle_phase)

Run time, run-time, or runtime may refer to:

Computing

Run time (program lifecycle phase), the period during which a computer program is executing

Runtime library, a program library designed to implement functions built into a programming language

Runtime system, software designed to support the execution of computer programs

Software execution, the process of performing instructions one by one during the run time phase

List of compilers https://en.wikipedia.org/wiki/List_of_compilers

• search on google and compare runtime errors vs compile errors:

;

3. In my opinion a very important thing to know : 3.1 the difference between build vs compile and the Build Lifecycle https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

3.2 the difference between this 3 things : compile vs build vs runtime

https://www.quora.com/What-is-the-difference-between-build-run-and-compile Fernando Padoan, A developer that's just a bit curious for language design Answered Feb 23 I’m going backwards in relation to other answers:

running is getting some binary executable (or a script, for interpreted languages) to be, well… executed as a new process on the computer; compiling is the process of parsing a program written in some high level language (higher if compared to machine code), checking it’s syntax, semantics, linking libraries, maybe doing some optimization, then creating a binary executable program as an output. This executable may be in the form of machine code, or some kind of byte code — that is, instructions targeting some kind of virtual machine; building usually involves checking and providing dependencies, inspecting code, compiling the code into binary, running automated tests and packaging the resulting binary[ies] and other assets (images, configuration files, libraries, etc.) into some specific format of deployable file. Note that most processes are optional and some depend on the targeted platform you are building for. As an example, packaging a Java application for Tomcat will output a .war file. Building a Win32 executable out of C++ code could just output the .exe program, or could also package it inside a .msi installer.

Change <?php echo $proxy ?> to ' . $proxy . '.

You use <?php when you're outputting HTML by leaving PHP mode with ?>. When you using echo, you have to use concatenation, or wrap your string in double quotes and use interpolation.

It's worth mentioning that specifically for IE, disabled=disabled works for anchor tags:

<a href="contact.html" onclick="unleashTheDragon();" disabled="disabled">Contact</a>

IE treats this as an disabled element and does not trigger click event. However, disabled is not a valid attribute on an anchor tag. Hence this won't work in other browsers. For them pointer-events:none is required in the styling.

UPDATE 1: So adding following rule feels like a cross-browser solution to me

UPDATE 2: For further compatibility, because IE will not form styles for anchor tags with disabled='disabled', so they will still look active. Thus, a:hover{} rule and styling is a good idea:

a[disabled="disabled"] {
        pointer-events: none; /* this is enough for non-IE browsers */
        color: darkgrey;      /* IE */
    }
        /* IE - disable hover effects */   
        a[disabled="disabled"]:hover {
            cursor:default;
            color: darkgrey;
            text-decoration:none;
        }

Working on Chrome, IE11, and IE8.
Of course, above CSS assumes anchor tags are rendered with disabled="disabled"

Do you mean full calendar days, or groups of 24 hours?

For simply 24 hours, assuming you're using Python's datetime, then the timedelta object already has a days property:

days = (a - b).days

For calendar days, you'll need to round a down to the nearest day, and b up to the nearest day, getting rid of the partial day on either side:

roundedA = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
roundedB = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
days = (roundedA - roundedB).days

The simplest and best solution is just to use XMLRoot attribute in your class, in which you wish to deserialize.

Like:

[XmlRoot(ElementName = "YourPreferableNameHere")]
public class MyClass{
...
}

Also, use the following Assembly :

using System.Xml.Serialization;

For Scala 2.11, if getLines doesn't do exactly what you want you can also copy the a file out of the jar to the local file system.

Here's a snippit that reads a binary google .p12 format API key from /resources, writes it to /tmp, and then uses the file path string as an input to a spark-google-spreadsheets write.

In the world of sbt-native-packager and sbt-assembly, copying to local is also useful with scalatest binary file tests. Just pop them out of resources to local, run the tests, and then delete.

import java.io.{File, FileOutputStream}
import java.nio.file.{Files, Paths}

def resourceToLocal(resourcePath: String) = {
  val outPath = "/tmp/" + resourcePath
  if (!Files.exists(Paths.get(outPath))) {
    val resourceFileStream = getClass.getResourceAsStream(s"/${resourcePath}")
    val fos = new FileOutputStream(outPath)
    fos.write(
      Stream.continually(resourceFileStream.read).takeWhile(-1 !=).map(_.toByte).toArray
    )
    fos.close()
  }
  outPath
}

val filePathFromResourcesDirectory = "google-docs-key.p12"
val serviceAccountId = "[something]@drive-integration-[something].iam.gserviceaccount.com"
val googleSheetId = "1nC8Y3a8cvtXhhrpZCNAsP4MBHRm5Uee4xX-rCW3CW_4"
val tabName = "Favorite Cities"

import spark.implicits
val df = Seq(("Brooklyn", "New York"), 
          ("New York City", "New York"), 
          ("San Francisco", "California")).
          toDF("City", "State")

df.write.
  format("com.github.potix2.spark.google.spreadsheets").
  option("serviceAccountId", serviceAccountId).
  option("credentialPath", resourceToLocal(filePathFromResourcesDirectory)).
  save(s"${googleSheetId}/${tabName}")

You may have to extract the jar using a zip application. Hopefully inside you'll find a collection of XML files.

Here is SQL for setting up an example:

CREATE TABLE employee(name varchar, paymentType varchar, amount bigint);

INSERT INTO employee VALUES('Aaron', 'salary', 100);
INSERT INTO employee VALUES('Aaron', 'bonus', 50);
INSERT INTO employee VALUES('Bob', 'salary', 50);
INSERT INTO employee VALUES('Bob', 'bonus', 0);

The Inject class is vulnerable to SQL injection. The query is dynamically pasted together with user input. The intent of the query was to show information about Bob. Either salary or bonus, based on user input. But the malicious user manipulates the input corrupting the query by tacking on the equivalent of an 'or true' to the where clause so that everything is returned, including the information about Aaron which was supposed to be hidden.

import java.sql.*;

public class Inject {

    public static void main(String[] args) throws SQLException {

        String url = "jdbc:postgresql://localhost/postgres?user=user&password=pwd";
        Connection conn = DriverManager.getConnection(url);

        Statement stmt = conn.createStatement();
        String sql = "SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='" + args[0] + "'";
        System.out.println(sql);
        ResultSet rs = stmt.executeQuery(sql);

        while (rs.next()) {
            System.out.println(rs.getString("paymentType") + " " + rs.getLong("amount"));
        }
    }
}

Running this, the first case is with normal usage, and the second with the malicious injection:

c:\temp>java Inject salary
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='salary'
salary 50

c:\temp>java Inject "salary' OR 'a'!='b"
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='salary' OR 'a'!='b'
salary 100
bonus 50
salary 50
bonus 0

You should not build your SQL statements with string concatenation of user input. Not only is it vulnerable to injection, but it has caching implications on the server as well (the statement changes, so less likely to get a SQL statement cache hit whereas the bind example is always running the same statement).

Here is an example of Binding to avoid this kind of injection:

import java.sql.*;

public class Bind {

    public static void main(String[] args) throws SQLException {

        String url = "jdbc:postgresql://localhost/postgres?user=postgres&password=postgres";
        Connection conn = DriverManager.getConnection(url);

        String sql = "SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?";
        System.out.println(sql);

        PreparedStatement stmt = conn.prepareStatement(sql);
        stmt.setString(1, args[0]);

        ResultSet rs = stmt.executeQuery();

        while (rs.next()) {
            System.out.println(rs.getString("paymentType") + " " + rs.getLong("amount"));
        }
    }
}

Running this with the same input as the previous example shows the malicious code does not work because there is no paymentType matching that string:

c:\temp>java Bind salary
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?
salary 50

c:\temp>java Bind "salary' OR 'a'!='b"
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?

I found this method worked for me:

$thisproduct = "my_product_id";
$array=array("$product1", "$product2", "$product3", "$product4");
if (in_array($thisproduct,$array)) {
    echo "Product found";
}

My answer comes from here

You can make a derived class, which will set the timeout property of the base WebRequest class:

using System;
using System.Net;

public class WebDownload : WebClient
{
    /// <summary>
    /// Time in milliseconds
    /// </summary>
    public int Timeout { get; set; }

    public WebDownload() : this(60000) { }

    public WebDownload(int timeout)
    {
        this.Timeout = timeout;
    }

    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address);
        if (request != null)
        {
            request.Timeout = this.Timeout;
        }
        return request;
    }
}

and you can use it just like the base WebClient class.

I wanted to suggest something like Michael Shimmin's but without hardcoding things like the element, or the CSS that is applied to it.

I'm only using jQuery for add/remove class, if you don't want to use jquery, you just need a replacement for add/removeClass

--Javascript

function highlight(el, durationMs) { 
  el = $(el);
  el.addClass('highlighted');
  setTimeout(function() {
    el.removeClass('highlighted')
  }, durationMs || 1000);
}

highlight(document.getElementById('tries'));

--CSS

#tries {
    border: 1px solid gray;
}

#tries.highlighted {
    border: 3px solid red;
}

No external libraries, works on both Python 2.7 and 3.x:

>>> list(set({"a":1, "b": 2}.values()))[0]
1

For aribtrary key just leave out .values()

>>> list(set({"a":1, "b": 2}))[0]
'a'

The accepted answer works, but if:

• you don't know the content's dimensions
• the content is dynamic
• you want to be future proof

use this:

.centered {
  position: fixed; /* or absolute */
  top: 50%;
  left: 50%;
  /* bring your own prefixes */
  transform: translate(-50%, -50%);
}

More information about centering content in this excellent CSS-Tricks article.

.center{
    height: 100vh;
    display: flex;
    justify-content: center;
    align-items: center;
}

Another great guide about flexboxs from CSS Tricks; http://css-tricks.com/snippets/css/a-guide-to-flexbox/

Using a (very) commonly used package is prefered:

im = plt.imread('image.png')

Write the telnet session inside a BAT Dos file and execute.

I'm not sure if I'm answering the question right, but here's a familiar example:

The return type of GetLastError() in Windows is nonzero if there was an error, or zero otherwise. The reverse is usually true of the return value of the function you called.

  $("#select_all").live("click", function(){
            $("input").prop("checked", $(this).prop("checked"));
    }
  });

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

%~dp0 may be a relative path. To convert it to a full path, try something like this:

pushd %~dp0
set script_dir=%CD%
popd

Create a class inherited from JavaScriptConverter. You must then implement three things:

Methods-

1. Serialize
2. Deserialize

Property-

1. SupportedTypes

You can use the JavaScriptConverter class when you need more control over the serialization and deserialization process.

JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.RegisterConverters(new JavaScriptConverter[] { new MyCustomConverter() });

DataObject dataObject = serializer.Deserialize<DataObject>(JsonData);

For Python version 3:

pip install pysqlite3 

If it's not working even when you already have Code Assist enabled, Eclipse's configuration files are probably corrupt. A solution that worked for me (on Eclipse 3.5.2) was to:

1. Close Eclipse.
2. Rename the workspace directory.
3. Start Eclipse. (This creates a new workspace directory.)
4. Import (with copy) the Java projects from the old workspace.

Playing with above answers, this one works for me

I came across over the following post: http://blogs.msdn.com/b/raulperez/archive/2010/03/19/c-intellisense-options.aspx

The issue is that the "IntelliSense" option in c++ is disabled. This link explains about the IntelliSense database configuration and options.

After enabling the database you must close and reopen visual studio for autocomplete use 'ctrl'+'space'

Please DISCARD the tablespace before IMPORT

I got same issue solution is below

1. First you have to drop your database name. if your database is not deleting you have flow me. For Windows system your directory will be C:/xampp/mysql/data/yourdabasefolder remove "yourdabasefolder"

2. Again you have to create new database and import your old sql file. It will be work

in order for this to work:

yourButton.isEnabled = false

you need to create an outlet in addition to your UI button.

For console projects in a step-by-step fashion, you'll have to first add the System.Windows.Forms reference. The following steps work in Visual Studio Community 2013 with .NET 4.5:

1. In Solution Explorer, expand your console project.
2. Right-click References, then click Add Reference...
3. In the Assemblies group, under Framework, select System.Windows.Forms.
4. Click OK.

Then, add the following using statement in with the others at the top of your code:

using System.Windows.Forms;

Then, add either of the following Clipboard.SetText statements to your code:

Clipboard.SetText("hello");
// OR
Clipboard.SetText(helloString);

And lastly, add STAThreadAttribute to your Main method as follows, to avoid a System.Threading.ThreadStateException:

[STAThreadAttribute]
static void Main(string[] args)
{
  // ...
}

I already showed this elsewhere on SO (How to use a variable in the format specifier statement? , not an exact duplicate IMHO), but I think it is worthwhile to place it here. It is possible to use the techniques from other answers for this question to make a simple function

function itoa(i) result(res)
  character(:),allocatable :: res
  integer,intent(in) :: i
  character(range(i)+2) :: tmp
  write(tmp,'(i0)') i
  res = trim(tmp)
end function

which you can use after without worrying about trimming and left-adjusting and without writing to a temporary variable:

OPEN(1, FILE = 'Output'//itoa(i)//'.TXT')

It requires Fortran 2003 because of the allocatable string.

And don't forget the ANT editor

For some reason Ant Editor does not show up in the search results for 'tab' or 'spaces' so can be missed.

• Ant » Editor » Formatter » Use tab character instead of spaces (uncheck it)

While I agree about not adhering blindly to dogmatic rules, does the "lock stealing" scenario seem so eccentric to you? A thread could indeed acquire the lock on your object "externally"(synchronized(theObject) {...}), blocking other threads waiting on synchronized instance methods.

If you don't believe in malicious code, consider that this code could come from third parties (for instance if you develop some sort of application server).

The "accidental" version seems less likely, but as they say, "make something idiot-proof and someone will invent a better idiot".

So I agree with the it-depends-on-what-the-class-does school of thought.

Edit following eljenso's first 3 comments:

I've never experienced the lock stealing problem but here is an imaginary scenario:

Let's say your system is a servlet container, and the object we're considering is the ServletContext implementation. Its getAttribute method must be thread-safe, as context attributes are shared data; so you declare it as synchronized. Let's also imagine that you provide a public hosting service based on your container implementation.

I'm your customer and deploy my "good" servlet on your site. It happens that my code contains a call to getAttribute.

A hacker, disguised as another customer, deploys his malicious servlet on your site. It contains the following code in the init method:

synchronized (this.getServletConfig().getServletContext()) {
   while (true) {}
}

Assuming we share the same servlet context (allowed by the spec as long as the two servlets are on the same virtual host), my call on getAttribute is locked forever. The hacker has achieved a DoS on my servlet.

This attack is not possible if getAttribute is synchronized on a private lock, because 3rd-party code cannot acquire this lock.

I admit that the example is contrived and an oversimplistic view of how a servlet container works, but IMHO it proves the point.

So I would make my design choice based on security consideration: will I have complete control over the code that has access to the instances? What would be the consequence of a thread's holding a lock on an instance indefinitely?

If you're wanting to run the script and end at a prompt (so you can inspect variables, etc), then use:

python -i test.py

That will run the script and then drop you into a Python interpreter.

It is not possible to write exception-safe code under the assumption that "any line can throw". The design of exception-safe code relies critically on certain contracts/guarantees that you are supposed to expect, observe, follow and implement in your code. It is absolutely necessary to have code that is guaranteed to never throw. There are other kinds of exception guarantees out there.

In other words, creating exception-safe code is to a large degree a matter of program design not just a matter of plain coding.

I translated the code sample in this blog post into Python: How to detect when the client closes the connection?, and it works well for me:

from ctypes import (
    CDLL, c_int, POINTER, Structure, c_void_p, c_size_t,
    c_short, c_ssize_t, c_char, ARRAY
)


__all__ = 'is_remote_alive',


class pollfd(Structure):
    _fields_ = (
        ('fd', c_int),
        ('events', c_short),
        ('revents', c_short),
    )


MSG_DONTWAIT = 0x40
MSG_PEEK = 0x02

EPOLLIN = 0x001
EPOLLPRI = 0x002
EPOLLRDNORM = 0x040

libc = CDLL(None)

recv = libc.recv
recv.restype = c_ssize_t
recv.argtypes = c_int, c_void_p, c_size_t, c_int

poll = libc.poll
poll.restype = c_int
poll.argtypes = POINTER(pollfd), c_int, c_int


class IsRemoteAlive:  # not needed, only for debugging
    def __init__(self, alive, msg):
        self.alive = alive
        self.msg = msg

    def __str__(self):
        return self.msg

    def __repr__(self):
        return 'IsRemoteClosed(%r,%r)' % (self.alive, self.msg)

    def __bool__(self):
        return self.alive


def is_remote_alive(fd):
    fileno = getattr(fd, 'fileno', None)
    if fileno is not None:
        if hasattr(fileno, '__call__'):
            fd = fileno()
        else:
            fd = fileno

    p = pollfd(fd=fd, events=EPOLLIN|EPOLLPRI|EPOLLRDNORM, revents=0)
    result = poll(p, 1, 0)
    if not result:
        return IsRemoteAlive(True, 'empty')

    buf = ARRAY(c_char, 1)()
    result = recv(fd, buf, len(buf), MSG_DONTWAIT|MSG_PEEK)
    if result > 0:
        return IsRemoteAlive(True, 'readable')
    elif result == 0:
        return IsRemoteAlive(False, 'closed')
    else:
        return IsRemoteAlive(False, 'errored')

If you have milliseconds in the date string, you can use the following.

select TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')From Dual;

And then convert it to Date with:

select trunc(TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')) From Dual;

It worked for me, hope it will help you as well.

Would like to add:

After update, such as

ALTER TABLE table_name modify column_name tinyint(4) NOT NULL;

If you get

ERROR 1138 (22004): Invalid use of NULL value

Make sure you update the table first to have values in the related column (so it's not null)

find -type f | wc -l

OR (If directory is current directory)

find . -type f | wc -l

foo = [1, 2, 3]
bar = [4, 5, 6]

foo.append(bar) --> [1, 2, 3, [4, 5, 6]]
foo.extend(bar) --> [1, 2, 3, 4, 5, 6]

http://docs.python.org/tutorial/datastructures.html

In my opinion you have two options:

• Just try to convert it to an int, but catch the exception:

  try:
      value = int(value)
  except ValueError:
      pass  # it was a string, not an int.
  

  This is the Ask Forgiveness approach.

• Explicitly test if there are only digits in the string:

  value.isdigit()
  

  str.isdigit() returns True only if all characters in the string are digits (0-9).

  The unicode / Python 3 str type equivalent is unicode.isdecimal() / str.isdecimal(); only Unicode decimals can be converted to integers, as not all digits have an actual integer value (U+00B2 SUPERSCRIPT 2 is a digit, but not a decimal, for example).

  This is often called the Ask Permission approach, or Look Before You Leap.

The latter will not detect all valid int() values, as whitespace and + and - are also allowed in int() values. The first form will happily accept ' +10 ' as a number, the latter won't.

If your expect that the user normally will input an integer, use the first form. It is easier (and faster) to ask for forgiveness rather than for permission in that case.

Well, this question is asked many times before, and the short typical answer is: It cannot be done by pure CSS. It's in the name: Cascading Style Sheets only supports styling in cascading direction, not up.

But in most circumstances where this effect is wished, like in the given example, there still is the possibility to use these cascading characteristics to reach the desired effect. Consider this pseudo markup:

<parent>
    <sibling></sibling>
    <child></child>
</parent>

The trick is to give the sibling the same size and position as the parent and to style the sibling instead of the parent. This will look like the parent is styled!

Now, how to style the sibling?

When the child is hovered, the parent is too, but the sibling is not. The same goes for the sibling. This concludes in three possible CSS selector paths for styling the sibling:

parent sibling { }
parent sibling:hover { }
parent:hover sibling { }

These different paths allow for some nice possibilities. For instance, unleashing this trick on the example in the question results in this fiddle:

div {position: relative}
div:hover {background: salmon}
div p:hover {background: white}
div p {padding-bottom: 26px}
div button {position: absolute; bottom: 0}

Obviously, in most cases this trick depends on the use of absolute positioning to give the sibling the same size as the parent, ánd still let the child appear within the parent.

Sometimes it is necessary to use a more qualified selector path in order to select a specific element, as shown in this fiddle which implements the trick multiple times in a tree menu. Quite nice really.

The accepted answer works great if you just want to use a different context in your partial. However, it doesn't let you reference any of the parent context. To pass in multiple arguments, you need to write your own helper. Here's a working helper for Handlebars 2.0.0 (the other answer works for versions <2.0.0):

Handlebars.registerHelper('renderPartial', function(partialName, options) {
    if (!partialName) {
        console.error('No partial name given.');
        return '';
    }
    var partial = Handlebars.partials[partialName];
    if (!partial) {
        console.error('Couldnt find the compiled partial: ' + partialName);
        return '';
    }
    return new Handlebars.SafeString( partial(options.hash) );
});

Then in your template, you can do something like:

{{renderPartial 'myPartialName' foo=this bar=../bar}}

And in your partial, you'll be able to access those values as context like:

<div id={{bar.id}}>{{foo}}</div>

find /path -type f \( -iname "*.jpg" -o -name "*.jpeg" -o -iname "*gif" \)

                        byte[] byteArray = stream.toByteArray();

                        out=new  FileOutputStream(land.getPath());
                        out.write(byteArray);

From the community documentation:

hibernate.hbm2ddl.auto Automatically validates or exports schema DDL to the database when the SessionFactory is created. With create-drop, the database schema will be dropped when the SessionFactory is closed explicitly.

e.g. validate | update | create | create-drop

So the list of possible options are,

• validate: validate the schema, makes no changes to the database.
• update: update the schema.
• create: creates the schema, destroying previous data.
• create-drop: drop the schema when the SessionFactory is closed explicitly, typically when the application is stopped.
• none: does nothing with the schema, makes no changes to the database

These options seem intended to be developers tools and not to facilitate any production level databases, you may want to have a look at the following question; Hibernate: hbm2ddl.auto=update in production?

You can use the answer suggested by @jombie, and:

• place the interface in a separate file, outside the entity class;
• use native query or not (the choice depended on your needs);
• don't override findAll() method for this purpose but use name of your choice;
• remember to return a List parametrized with your new interface (e.g. List<SmallProject>).

I can't comment on the previous answers since I haven't tried them. However I know the following strategy works for me. It is a bit less elegant but gets the job done. It also doesn't require breaking code into chunks like some other approaches seem to do. In my case, that was not an option, because my code had recursive calls to the logic that was being looped; i.e., there was no practical way to just hop out of the loop, then be able to resume in some way by using global vars to preserve current state since those globals could be changed by references to them in a subsequent recursed call. So I needed a straight-forward way that would not offer a chance for the code to compromise the data state integrity.

Assuming the "stop script?" dialog is coming up during a for() loop executuion after a number of iterations (in my case, about 8-10), and messing with the registry is no option, here was the fix (for me, anyway):

var anarray = [];
var array_member = null;
var counter = 0; // Could also be initialized to the max desired value you want, if
                 // planning on counting downward.

function func_a()
{
 // some code
 // optionally, set 'counter' to some desired value.
 ...
 anarray = { populate array with objects to be processed that would have been
             processed by a for() }
 // 'anarry' is going to be reduced in size iteratively.  Therefore, if you need
 //  to maintain an orig. copy of it, create one, something like 'anarraycopy'.
 //  If you need only a shallow copy, use 'anarraycopy = anarray.slice(0);'
 //  A deep copy, depending on what kind of objects you have in the array, may be
 //  necessary.  The strategy for a deep copy will vary and is not discussed here.
 //  If you need merely to record the array's orig. size, set a local or
 //  global var equal to 'anarray.length;', depending on your needs.
 // - or -
 // plan to use 'counter' as if it was 'i' in a for(), as in
 // for(i=0; i < x; i++ {...}

   ...

   // Using 50 for example only.  Could be 100, etc. Good practice is to pick something
   // other than 0 due to Javascript engine processing; a 0 value is all but useless
   // since it takes time for Javascript to do anything. 50 seems to be good value to
   // use. It could be though that what value to use does  depend on how much time it
   // takes the code in func_c() to execute, so some profiling and knowing what the 
   // most likely deployed user base is going to be using might help. At the same 
   // time, this may make no difference.  Not entirely sure myself.  Also, 
   // using "'func_b()'" instead of just "func_b()" is critical.  I've found that the
   // callback will not occur unless you have the function in single-quotes.

   setTimeout('func_b()', 50);

  //  No more code after this.  function func_a() is now done.  It's important not to
  //  put any more code in after this point since setTimeout() does not act like
  //  Thread.sleep() in Java.  Processing just continues, and that is the problem
  //  you're trying to get around.

} // func_a()


function func_b()
{
 if( anarray.length == 0 )
 {
   // possibly do something here, relevant to your purposes
   return;
 }
//  -or- 
if( counter == x ) // 'x' is some value you want to go to.  It'll likely either
                   // be 0 (when counting down) or the max desired value you
                   // have for x if counting upward.
{
  // possibly do something here, relevant to your purposes
  return;
}

array_member = anarray[0];
anarray.splice(0,1); // Reduces 'anarray' by one member, the one at anarray[0].
                     // The one that was at anarray[1] is now at
                     // anarray[0] so will be used at the next iteration of func_b().

func_c();

setTimeout('func_b()', 50);

} // func_b()


function func_c()
{
  counter++; // If not using 'anarray'.  Possibly you would use
             // 'counter--' if you set 'counter' to the highest value
             // desired and are working your way backwards.

  // Here is where you have the code that would have been executed
  // in the for() loop.  Breaking out of it or doing a 'continue'
  // equivalent can be done with using 'return;' or canceling 
  // processing entirely can be done by setting a global var
  // to indicate the process is cancelled, then doing a 'return;', as in
  // 'bCancelOut = true; return;'.  Then in func_b() you would be evaluating
  // bCancelOut at the top to see if it was true.  If so, you'd just exit from
  // func_b() with a 'return;'

} // func_c()

print(platform.python_version())

This prints something like

I wanted to add my experience on that. Indeed EF, when you add an object to the context, it changes the state of all the children and related entities to Added. Although there is a small exception in the rule here: if the children/related entities are being tracked by the same context, EF does understand that these entities exist and doesn't add them. The problem happens when for example, you load the children/related entities from some other context or a web ui etc and then yes, EF doesn't know anything about these entities and goes and adds all of them. To avoid that, just get the keys of the entities and find them (e.g. context.Students.FirstOrDefault(s => s.Name == "Alice")) in the same context in which you want to do the addition.

I realize my opinion is probably not the popular one, but I guess I have a hard time jumping on the Linq-y band wagon. It's nifty. It's condensed. I get that and I'm not opposed to using it where it's appropriate. Maybe it's just me, but I feel like people have stopped thinking about creating utility functions to accomplish what they want and instead prefer to litter their code with (sometimes) excessively long lines of Linq code for the sake of creating a dense 1-liner.

I'm not saying that any of the Linq answers that people have provided here are bad, but I guess I feel like there is the potential that these single lines of code can start to grow longer and more obscure as you need to handle various situations. What if your array is null? What if you want a delimited string instead of just purely concatenated? What if some of the integers in your array are double-digit and you want to pad each value with leading zeros so that the string for each element is the same length as the rest?

Taking one of the provided answers as an example:

        result = arr.Aggregate(string.Empty, (s, i) => s + i.ToString());

If I need to worry about the array being null, now it becomes this:

        result = (arr == null) ? null : arr.Aggregate(string.Empty, (s, i) => s + i.ToString());

If I want a comma-delimited string, now it becomes this:

        result = (arr == null) ? null : arr.Skip(1).Aggregate(arr[0].ToString(), (s, i) => s + "," + i.ToString());

This is still not too bad, but I think it's not obvious at a glance what this line of code is doing.

Of course, there's nothing stopping you from throwing this line of code into your own utility function so that you don't have that long mess mixed in with your application logic, especially if you're doing it in multiple places:

    public static string ToStringLinqy<T>(this T[] array, string delimiter)
    {
        // edit: let's replace this with a "better" version using a StringBuilder
        //return (array == null) ? null : (array.Length == 0) ? string.Empty : array.Skip(1).Aggregate(array[0].ToString(), (s, i) => s + "," + i.ToString());
        return (array == null) ? null : (array.Length == 0) ? string.Empty : array.Skip(1).Aggregate(new StringBuilder(array[0].ToString()), (s, i) => s.Append(delimiter).Append(i), s => s.ToString());
    }

But if you're going to put it into a utility function anyway, do you really need it to be condensed down into a 1-liner? In that case why not throw in a few extra lines for clarity and take advantage of a StringBuilder so that you're not doing repeated concatenation operations:

    public static string ToStringNonLinqy<T>(this T[] array, string delimiter)
    {
        if (array != null)
        {
            // edit: replaced my previous implementation to use StringBuilder
            if (array.Length > 0)
            {
                StringBuilder builder = new StringBuilder();

                builder.Append(array[0]);
                for (int i = 1; i < array.Length; i++)
                {
                    builder.Append(delimiter);
                    builder.Append(array[i]);
                }

                return builder.ToString()
            }
            else
            {
                return string.Empty;
            }
        }
        else
        {
            return null;
        }
    }

And if you're really so concerned about performance, you could even turn it into a hybrid function that decides whether to do string.Join or to use a StringBuilder depending on how many elements are in the array (this is a micro-optimization, not worth doing in my opinion and possibly more harmful than beneficial, but I'm using it as an example for this problem):

    public static string ToString<T>(this T[] array, string delimiter)
    {
        if (array != null)
        {
            // determine if the length of the array is greater than the performance threshold for using a stringbuilder
            // 10 is just an arbitrary threshold value I've chosen
            if (array.Length < 10)
            {
                // assumption is that for arrays of less than 10 elements
                // this code would be more efficient than a StringBuilder.
                // Note: this is a crazy/pointless micro-optimization.  Don't do this.
                string[] values = new string[array.Length];

                for (int i = 0; i < values.Length; i++)
                    values[i] = array[i].ToString();

                return string.Join(delimiter, values);
            }
            else
            {
                // for arrays of length 10 or longer, use a StringBuilder
                StringBuilder sb = new StringBuilder();

                sb.Append(array[0]);
                for (int i = 1; i < array.Length; i++)
                {
                    sb.Append(delimiter);
                    sb.Append(array[i]);
                }

                return sb.ToString();
            }
        }
        else
        {
            return null;
        }
    }

For this example, the performance impact is probably not worth caring about, but the point is that if you are in a situation where you actually do need to be concerned with the performance of your operations, whatever they are, then it will most likely be easier and more readable to handle that within a utility function than using a complex Linq expression.

That utility function still looks kind of clunky. Now let's ditch the hybrid stuff and do this:

    // convert an enumeration of one type into an enumeration of another type
    public static IEnumerable<TOut> Convert<TIn, TOut>(this IEnumerable<TIn> input, Func<TIn, TOut> conversion)
    {
        foreach (TIn value in input)
        {
            yield return conversion(value);
        }
    }

    // concatenate the strings in an enumeration separated by the specified delimiter
    public static string Delimit<T>(this IEnumerable<T> input, string delimiter)
    {
        IEnumerator<T> enumerator = input.GetEnumerator();

        if (enumerator.MoveNext())
        {
            StringBuilder builder = new StringBuilder();

            // start off with the first element
            builder.Append(enumerator.Current);

            // append the remaining elements separated by the delimiter
            while (enumerator.MoveNext())
            {
                builder.Append(delimiter);
                builder.Append(enumerator.Current);
            }

            return builder.ToString();
        }
        else
        {
            return string.Empty;
        }
    }

    // concatenate all elements
    public static string ToString<T>(this IEnumerable<T> input)
    {
        return ToString(input, string.Empty);
    }

    // concatenate all elements separated by a delimiter
    public static string ToString<T>(this IEnumerable<T> input, string delimiter)
    {
        return input.Delimit(delimiter);
    }

    // concatenate all elements, each one left-padded to a minimum length
    public static string ToString<T>(this IEnumerable<T> input, int minLength, char paddingChar)

        return input.Convert(i => i.ToString().PadLeft(minLength, paddingChar)).Delimit(string.Empty);
    }

Now we have separate and fairly compact utility functions, each of which are arguable useful on their own.

Ultimately, my point is not that you shouldn't use Linq, but rather just to say don't forget about the benefits of creating your own utility functions, even if they are small and perhaps only contain a single line that returns the result from a line of Linq code. If nothing else, you'll be able to keep your application code even more condensed than you could achieve with a line of Linq code, and if you are using it in multiple places, then using a utility function makes it easier to adjust your output in case you need to change it later.

For this problem, I'd rather just write something like this in my application code:

        int[] arr = { 0, 1, 2, 3, 0, 1 };

        // 012301
        result = arr.ToString<int>();

        // comma-separated values
        // 0,1,2,3,0,1
        result = arr.ToString(",");

        // left-padded to 2 digits
        // 000102030001
        result = arr.ToString(2, '0');

const fs = require('fs');

check in the function like below,

if(fs.existsSync(<path_that_need_to_be_checked>)){
  // enter the code to excecute after the folder is there.
}
else{
  // Below code to create the folder, if its not there
  fs.mkdir('<folder_name>', cb function);
}

Order of magnitude: zero.

In other words, you won't see your throughput cut in half, or anything like it, when you add TLS. Answers to the "duplicate" question focus heavily on application performance, and how that compares to SSL overhead. This question specifically excludes application processing, and seeks to compare non-SSL to SSL only. While it makes sense to take a global view of performance when optimizing, that is not what this question is asking.

The main overhead of SSL is the handshake. That's where the expensive asymmetric cryptography happens. After negotiation, relatively efficient symmetric ciphers are used. That's why it can be very helpful to enable SSL sessions for your HTTPS service, where many connections are made. For a long-lived connection, this "end-effect" isn't as significant, and sessions aren't as useful.

Here's an interesting anecdote. When Google switched Gmail to use HTTPS, no additional resources were required; no network hardware, no new hosts. It only increased CPU load by about 1%.

In case you want to replace values in place, you can update your original list with values from a list comprehension by assigning to the whole slice of the original.

data = [*range(11)] # [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
id_before = id(data)
data[:] = [x if x % 2 else None for x in data]
data
# Out: [None, 1, None, 3, None, 5, None, 7, None, 9, None]
id_before == id(data)  # check if list is still the same
# Out: True

If you have multiple names pointing to the original list, for example you wrote data2=data before changing the list and you skip the slice notation for assigning to data, data will rebind to point to the newly created list while data2 still points to the original unchanged list.

data = [*range(11)] # [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
data2 = data
id_before = id(data)
data = [x if x % 2 else None for x in data]  # no [:] here
data
# Out: [None, 1, None, 3, None, 5, None, 7, None, 9, None]
id_before == id(data)  # check if list is still the same
# Out: False
data2
# Out: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Note: This is no recommendation for generally preferring one over the other (changing list in place or not), but behavior you should be aware of.

An <iframe> background can be changed like this:

<iframe allowtransparency="true" style="background: #FFFFFF;" 
    src="http://zingaya.com/widget/9d043c064dc241068881f045f9d8c151" 
    frameborder="0" height="184" width="100%">
</iframe>

I don't think it's possible to change the background of the page that you have loaded in the iframe.

Some view have there own double tap recognizers built in (MKMapView being an example). To get around this you will need to implement UIGestureRecognizerDelegate method shouldRecognizeSimultaneouslyWithGestureRecognizer and return YES:

First implement your double and single recognizers:

// setup gesture recognizers
UITapGestureRecognizer* singleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                                action:@selector(mapViewTapped:)];
singleTapRecognizer.delegate = self;
singleTapRecognizer.numberOfTapsRequired = 1;


UITapGestureRecognizer* doubleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                                      action:@selector(mapViewDoubleTapped:)];
doubleTapRecognizer.delegate = self;    // this allows
doubleTapRecognizer.numberOfTapsRequired = 2;
[singleTapRecognizer requireGestureRecognizerToFail:doubleTapRecognizer];

And then implement:

#pragma mark UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer {  return YES; }

I also found the apache commons IOUtils class , so :

InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString));

declare @locationType varchar(50);
declare @locationID int;

SELECT column1, column2
FROM viewWhatever
WHERE
@locationID = 
  CASE @locationType
      WHEN 'location' THEN account_location
      WHEN 'area' THEN xxx_location_area 
      WHEN 'division' THEN xxx_location_division 
  END

Keep the java script code inside the body tag

<body> 
   <script type="text/javascript">
   </script>
</body>

Alias to move one tag to a different commit.

In your sample, to move commit with hash e2ea1639 do: git tagm v0.1 e2ea1639.

For pushed tags, use git tagmp v0.1 e2ea1639.

Both alias keeps you original date and message. If you use git tag -d you lost your original message.

Save them on your .gitconfig file

# Return date of tag. (To use in another alias)
tag-date = "!git show $1 | awk '{ if ($1 == \"Date:\") { print substr($0, index($0,$3)) }}' | tail -2 | head -1 #"

# Show tag message
tag-message = "!git show $1 | awk -v capture=0 '{ if(capture) message=message\"\\n\"$0}; BEGIN {message=\"\"}; { if ($1 == \"Date:\" && length(message)==0 ) {capture=1}; if ($1 == \"commit\" ) {capture=0}  }; END { print message }' | sed '$ d' | cat -s #"

### Move tag. Use: git tagm <tagname> <newcommit> 
tagm = "!GIT_TAG_MESSAGE=$(git tag-message $1) && GIT_COMMITTER_DATE=$(git tag-date $1) && git tag-message $1 && git tag -d $1 && git tag -a $1 $2 -m \"$GIT_TAG_MESSAGE\" #"

### Move pushed tag. Use: git tagmp <tagname> <newcommit> 
tagmp = "!git tagm $1 $2 && git push --delete origin $1 && git push origin $1 #"

Here is a good example on how to do a command if a file does or does not exist:

if exist C:\myprogram\sync\data.handler echo Now Exiting && Exit
if not exist C:\myprogram\html\data.sql Exit

We will take those three files and put it in a temporary place. After deleting the folder, it will restore those three files.

xcopy "test" "C:\temp"
xcopy "test2" "C:\temp"
del C:\myprogram\sync\
xcopy "C:\temp" "test"
xcopy "C:\temp" "test2"
del "c:\temp"

Use the XCOPY command:

xcopy "C:\myprogram\html\data.sql"  /c /d /h /e /i /y  "C:\myprogram\sync\"

I will explain what the /c /d /h /e /i /y means:

  /C           Continues copying even if errors occur.
  /D:m-d-y     Copies files changed on or after the specified date.
               If no date is given, copies only those files whose
               source time is newer than the destination time.
  /H           Copies hidden and system files also.
  /E           Copies directories and subdirectories, including empty ones.
               Same as /S /E. May be used to modify /T.
  /T           Creates directory structure, but does not copy files. Does not
               include empty directories or subdirectories. /T /E includes
  /I           If destination does not exist and copying more than one file,
               assumes that destination must be a directory.
  /Y           Suppresses prompting to confirm you want to overwrite an
               existing destination file.

Call other batch file with option sync.bat myprogram.ini.

I am not sure what you mean by this, but if you just want to open both of these files you just put the path of the file like

Path/sync.bat
Path/myprogram.ini

If it was in the Bash environment it was easy for me, but I do not know how to test if a file or folder exists and if it is a file or folder.

You are using a batch file. You mentioned earlier you have to create a .bat file to use this:

I have to create a .BAT file that does this:

Try the following regex:

This will match every character that is not (^) in the interval 0-9.

Demo.

$(selectedDOM).find();

function looking for all dom objects inside the selected DOM. i.e.

<div id="mainDiv">
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <div id="innerDiv">
         <a href="#">link</a>
         <p>Paragraph 3</p>
    </div>
</div>

here if you write;

$("#mainDiv").find("p");

you will get tree p elements together. On the other side,

$("#mainDiv").children("p");

Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.

The expression between the <%= %> is evaluated before the c:if tag is evaluated. So, supposing that |request.isUserInRole| returns |true|, your example would be evaluated to this first:

<c:if test="true">
    <li>user</li>
</c:if>

and then the c:if tag would be executed.

Start a timer in the constructor of your class. The interval is in milliseconds so 5*60 seconds = 300 seconds = 300000 milliseconds.

static void Main(string[] args)
{
    System.Timers.Timer timer = new System.Timers.Timer();
    timer.Interval = 300000;
    timer.Elapsed += timer_Elapsed;
    timer.Start();
}

Then call GetData() in the timer_Elapsed event like this:

static void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    //YourCode
}

Many outdated, over-complicated and weird answers here. The reason is that the documentation is inadequate and the simple solution is to just use basicConfig() and set it as follows:

logging.basicConfig(datefmt='%Y-%m-%d %H:%M:%S', format='{asctime}.{msecs:0<3.0f} {name} {threadName} {levelname}: {message}', style='{')

The trick here was that you have to also set the datefmt argument, as the default messes it up and is not what is (currently) shown in the how-to python docs. So rather look here.

An alternative and possibly cleaner way, would have been to override the default_msec_format variable with:

formatter = logging.Formatter('%(asctime)s')
formatter.default_msec_format = '%s.%03d'

However, that did not work for unknown reasons.

_{PS. I am using Python 3.8.}

If you want to authenticate against a user name and password and without an authorization cookie, the MVC4 Authorize attribute won't work out of the box. However, you can add the following helper method to your controller to accept basic authentication headers. Call it from the beginning of your controller's methods.

void EnsureAuthenticated(string role)
{
    string[] parts = UTF8Encoding.UTF8.GetString(Convert.FromBase64String(Request.Headers.Authorization.Parameter)).Split(':');
    if (parts.Length != 2 || !Membership.ValidateUser(parts[0], parts[1]))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "No account with that username and password"));
    if (role != null && !Roles.IsUserInRole(parts[0], role))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "An administrator account is required"));
}

From the client side, this helper creates a HttpClient with the authentication header in place:

static HttpClient CreateBasicAuthenticationHttpClient(string userName, string password)
{
    var client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(userName + ':' + password)));
    return client;
}

1. Open SQL Server Configuration Manager, and then expand SQL Server 2012 Network Configuration.
2. Click Protocols for InstanceName, and then make sure TCP/IP is enabled in the right panel and double-click TCP/IP.
3. On the Protocol tab, notice the value of the Listen All item.
4. Click the IP Addresses tab: If the value of Listen All is yes, the TCP/IP port number for this instance of SQL Server 2012 is the value of the TCP Dynamic Ports item under IPAll. If the value of Listen All is no, the TCP/IP port number for this instance of SQL Server 2012 is the value of the TCP Dynamic Ports item for a specific IP address.
5. Make sure the TCP Port is 1433.
6. Click OK.

If there are any more questions, please let me know.

OpenSSL provides a passwd command that can encrypt but doesn't decrypt as it only does hashes. You could also download something like aesutil so you can use a capable and well-known symmetric encryption routine.

For example:

#!/bin/sh    
# using aesutil
SALT=$(mkrand 15) # mkrand generates a 15-character random passwd
MYENCPASS="i/b9pkcpQAPy7BzH2JlqHVoJc2mNTBM=" # echo "passwd" | aes -e -b -B -p $SALT 
MYPASS=$(echo "$MYENCPASS" | aes -d -b -p $SALT)

# and usage
serverControl.sh -u admin -p $MYPASS -c shutdown

There is one additional thing you may need to know: If the host or subdomain part of the url contain an underscore, IE9 (have not tested other versions) cannot write cookies.

So be careful about that. :-)

It is a bug in Eclipse. I had exactly the same problem, also on Ubuntu with Eclipse Java EE Juno.

Here is the workaround that worked for me:

1. Close Eclipse
2. In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings delete the following two files:
   • org.eclipse.wst.server.core.prefs
   • org.eclipse.jst.server.tomcat.core.prefs
3. Restart Eclipse

Since C++11 you can use std::chrono:

• get current system time: std::chrono::system_clock::now()
• get time since epoch: .time_since_epoch()
• translate the underlying unit to milliseconds: duration_cast<milliseconds>(d)
• translate std::chrono::milliseconds to integer (uint64_t to avoid overflow)

#include <chrono>
#include <cstdint>
#include <iostream>

uint64_t timeSinceEpochMillisec() {
  using namespace std::chrono;
  return duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();
}

int main() {
  std::cout << timeSinceEpochMillisec() << std::endl;
  return 0;
}

There are lot of different Timers in the .NET BCL:

• System.Timers.Timer
• System.Threading.Timer
• System.Windows.Forms.Timer
• System.Web.UI.Timer
• System.Windows.Threading.DispatcherTimer

When to use which?

• System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Windows.Forms.Timer (.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.
• System.Web.UI.Timer (.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
• System.Windows.Threading.DispatcherTimer, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.

Some of them needs explicit Start call to begin ticking (for example System.Timers, System.Windows.Forms). And an explicit Stop to finish ticking.

using TimersTimer = System.Timers.Timer;

static void Main(string[] args)
{
    var timer = new TimersTimer(1000);
    timer.Elapsed += (s, e) => Console.WriteLine("Beep");
    Thread.Sleep(1000); //1 second delay
    timer.Start();
    Console.ReadLine();
    timer.Stop();

}

While on the other hand there are some Timers (like: System.Threading) where you don't need explicit Start and Stop calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.

So, the following two versions will work in the same way:

using ThreadingTimer = System.Threading.Timer;

static void Main(string[] args)
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
    Console.ReadLine();
}

using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
    StartTimer();
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

But if your timer disposed then it will stop ticking obviously.

using ThreadingTimer = System.Threading.Timer; 

static void Main(string[] args)
{
    StartTimer();
    GC.Collect(0);
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

Slightly changed to David Murdoch's code for generic library

Function HasByName(cSheetName As String, _ 
                   Optional oWorkBook As Excel.Workbook) As Boolean

    HasByName = False
    Dim wb

    If oWorkBook Is Nothing Then
        Set oWorkBook = ThisWorkbook
    End If

    For Each wb In oWorkBook.Worksheets
        If wb.Name = cSheetName Then
            HasByName = True
            Exit Function
        End If
    Next wb
End Function

You can Use KeyPress instead of KeyUp or KeyDown its more efficient and here's how to handle

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == (char)Keys.Enter)
        {
            e.Handled = true;
            button1.PerformClick();
        }
    }

hope it works

If you don't mind including a utility library, lodash library has _.pad, _.padLeft and _.padRight functions.

This is a different answer, but this might help to help people who are trying to save data and then read it again.
There is hickle which is faster than pickle and easier.
I tried to save and read it in pickle dump but while reading there were lot of problems and wasted an hour and still didn't find solution though I was working on my own data to create a chat bot.

vec_x and vec_y are numpy arrays:

data=[vec_x,vec_y]
hkl.dump( data, 'new_data_file.hkl' )

Then you just read it and perform the operations:

data2 = hkl.load( 'new_data_file.hkl' )
