The short answer to 2nd part of the question is simply that CString class doesn't provide a direct typecast conversion by design and what you are doing is kind of cheat.

A longer answer is the following:

The reason you can typcast CString to LPCTSTR is because CString provides this facility by overriding operator=. By design it provides conversion to only LPCTSTR pointer so the string value can't be modified with this pointer.

In other words, it simply doesn't provide an overload operator= to convert the CString into LPSTR for the same reason as above. They don't want to allow altering the string value this way.

So essentially, the trick is to use the operator CString provide and get this:

LPTSTR lptstr = (LPCTSTR) string; // CString provide this operator overload

Now LPTSTR can be further type casted to LPSTR :)

dispinfo.item.pszText = LPTSTR( lpfzfd); // accomplish the cheat :P

The correct way to get LPTSTR from 'CString' is this though (complete example):

CString str = _T("Hello");
LPTSTR lpstr = str.GetBuffer(str.GetAllocLength());
str.ReleaseBuffer(); // you must call this function if you change the string above with the pointer

Again because the GetBuffer() returns LPTSTR for that reason that now you can modify :)

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

npm install serve-index

var express    = require('express')
var serveIndex = require('serve-index')
var path = require('path')
var serveStatic = require('serve-static')
var app = express()
var port = process.env.PORT || 3000;
/**for files */
app.use(serveStatic(path.join(__dirname, 'public')));
/**for directory */
app.use('/', express.static('public'), serveIndex('public', {'icons': true}))

// Listen
app.listen(port,  function () {
  console.log('listening on port:',+ port );
})

Just solved the issue. After digging around for a while longer, I found this SO post which covers the exact same situation. It got me in the right track.

Basically, the XmlSerializer needs to know the default namespace if derived classes are included as extra types. The exact reason why this has to happen is still unknown but, still, serialization is working now.

You can kill Jenkins safely. It will catch SIGTERM and SIGINT and perform an orderly shutdown. However, if Jenkins was in the middle of building something, it will abort the builds and they will show up gray in the status display.

If you want to avoid this, you must put Jenkins into shutdown mode to prevent it from starting new builds and wait until currently running builds are done before killing Jenkins.

You can also use the Jenkins command line interface and tell Jenkins to safe-shutdown, which does the same. You can find more info on Jenkins cli at http://YOURJENKINS/cli

You cannot upload like this.

You need a physical path exactly like in your local

C:/Users/puneet verma/Downloads/

What you can do is create some local path where your server is working. Hence you can store and retrieve the file. If you bought some domain from any websites there will be path to upload the files. You create these variable as static constant and use it based on the server you are working (Local/Website).

Here's a quick-and-dirty technique I have used:

SELECT * FROM Tags
WHERE '|ruby|rails|scruffy|rubyonrails|'
LIKE '%|' + Name + '|%'

So here's the C# code:

string[] tags = new string[] { "ruby", "rails", "scruffy", "rubyonrails" };
const string cmdText = "select * from tags where '|' + @tags + '|' like '%|' + Name + '|%'";

using (SqlCommand cmd = new SqlCommand(cmdText)) {
   cmd.Parameters.AddWithValue("@tags", string.Join("|", tags);
}

Two caveats:

• The performance is terrible. LIKE "%...%" queries are not indexed.
• Make sure you don't have any |, blank, or null tags or this won't work

There are other ways to accomplish this that some people may consider cleaner, so please keep reading.

Since the other question was (possibly wrongfully so?) locked, I will just put this here:

show authors with their commit counts:

git shortlog -nse

find all commits for specific USERNAME:

git log --author=USERNAME --oneline | awk '{print $1}' | xargs git show

1. First download WinBGIm from http://winbgim.codecutter.org/ Extract it.
2. Copy graphics.h and winbgim.h files in include folder of your compiler directory
3. Copy libbgi.a to lib folder of your compiler directory
4. In code::blocks open Settings >> Compiler and debugger >>linker settings click Add button in link libraries part and browse and select libbgi.a file
5. In right part (i.e. other linker options) paste commands -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32

Android studio 4.0.1 Kotlin 1.3.72

Android Navigation architecture component.

The following code works for me:

findNavController().popBackStack()

Maybe these answers above are old but with the new Android Studios 1, you do the following to see the module to run on 1.7 (or 1.6 if you prefer). Click File --> Project Structure. Select the module you want to run and then under "Source Compatibility" and "Target Compatibility", select 1.7. Click "OK".

I had issues with the solution by @HenkHolterman even with the fix by @RobinAndersson.

Reading up on the ISO 8601 standard resolves the issue nicely. Use the first Thursday as the target and not Monday. The code below will work for Week 53 of 2009 as well.

public static DateTime FirstDateOfWeekISO8601(int year, int weekOfYear)
{
    DateTime jan1 = new DateTime(year, 1, 1);
    int daysOffset = DayOfWeek.Thursday - jan1.DayOfWeek;

    // Use first Thursday in January to get first week of the year as
    // it will never be in Week 52/53
    DateTime firstThursday = jan1.AddDays(daysOffset);
    var cal = CultureInfo.CurrentCulture.Calendar;
    int firstWeek = cal.GetWeekOfYear(firstThursday, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);

    var weekNum = weekOfYear;
    // As we're adding days to a date in Week 1,
    // we need to subtract 1 in order to get the right date for week #1
    if (firstWeek == 1)
    {
        weekNum -= 1;
    }

    // Using the first Thursday as starting week ensures that we are starting in the right year
    // then we add number of weeks multiplied with days
    var result = firstThursday.AddDays(weekNum * 7);

    // Subtract 3 days from Thursday to get Monday, which is the first weekday in ISO8601
    return result.AddDays(-3);
}       

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

just trigger a click, it's work for me:

DECLARE @source varbinary(max),  
@encoded_base64 varchar(max),  
@decoded varbinary(max) 
SET @source = CONVERT(varbinary(max), 'welcome') 
-- Convert from varbinary to base64 string 
SET @encoded_base64 = CAST(N'' AS xml).value('xs:base64Binary(sql:variable       
("@source"))', 'varchar(max)') 
  -- Convert back from base64 to varbinary 
   SET @decoded = CAST(N'' AS xml).value('xs:base64Binary(sql:variable             
  ("@encoded_base64"))', 'varbinary(max)') 

 SELECT
  CONVERT(varchar(max), @source) AS [Source varchar], 
   @source AS [Source varbinary], 
     @encoded_base64 AS [Encoded base64], 
     @decoded AS [Decoded varbinary], 
     CONVERT(varchar(max), @decoded) AS [Decoded varchar]

This is usefull for encode and decode.

Suppose i have .config file in console app and now am getting like below.

Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName + "\\YourFolderName\\log4net.config";

You can slecet sent item /email and drag to desktop , it will automatic created new file on desktop. Then you can attach and send it in to new emails.

I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:

s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])

Network connection problems.
Maybe due to the persistent connection timeout.
The best way is to change to another network.

You could use jQuery and an Ajax call to post the specific update back to your server with Javascript.

It would look something like this:

function updatePostID(val, comment)
{

    var args = {};
    args.PostID = val;
    args.Comment = comment;

    $.ajax({
     type: "POST",
     url: controllerActionMethodUrlHere,
     contentType: "application/json; charset=utf-8",
     data: args,
     dataType: "json",
     success: function(msg) 
     {
        // Something afterwards here

     }
    });

}

Please change your project-level build.gradle file in which you have to change your dependencies class path of google-services or build.gradle path.

buildscript {

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

Select just column_name from information schema and put the result of this query into variable. Then test the variable to decide if table needs alteration or not.

P.S. Don't foget to specify TABLE_SCHEMA for COLUMNS table as well.

This one worked fine for me.

  String cc2 = "2202";
  String text2 = String.valueOf(Character.toChars(Integer.parseInt(cc2, 16)));

Now text2 will have ?.

$(document).ready(function(){
$('#userForm').on('submit', function(e){
        e.preventDefault();
//I had an issue that the forms were submitted in geometrical progression after the next submit. 
// This solved the problem.
        e.stopImmediatePropagation();
    // show that something is loading
    $('#response').html("<b>Loading data...</b>");

    // Call ajax for pass data to other place
    $.ajax({
    type: 'POST',
    url: 'somephpfile.php',
    data: $(this).serialize() // getting filed value in serialize form
    })
    .done(function(data){ // if getting done then call.

    // show the response
    $('#response').html(data);

    })
    .fail(function() { // if fail then getting message

    // just in case posting your form failed
    alert( "Posting failed." );

    });

    // to prevent refreshing the whole page page
    return false;

    });

Here I came up with universal method to navigate from any place to root.

1. You create a new Class file with this class, so that it's accessible from anywhere in your project:

   import UIKit
   
   class SharedControllers
   {
       static func navigateToRoot(viewController: UIViewController)
       {
           var nc = viewController.navigationController
   
           // If this is a normal view with NavigationController, then we just pop to root.
           if nc != nil
           {
               nc?.popToRootViewControllerAnimated(true)
               return
           }
   
           // Most likely we are in Modal view, so we will need to search for a view with NavigationController.
           let vc = viewController.presentingViewController
   
           if nc == nil
           {
               nc = viewController.presentingViewController?.navigationController
           }
   
           if nc == nil
           {
               nc = viewController.parentViewController?.navigationController
           }
   
           if vc is UINavigationController && nc == nil
           {
               nc = vc as? UINavigationController
           }
   
           if nc != nil
           {
               viewController.dismissViewControllerAnimated(false, completion:
                   {
                       nc?.popToRootViewControllerAnimated(true)
               })
           }
       }
   }
   

2. Usage from anywhere in your project:

   {
       ...
       SharedControllers.navigateToRoot(self)
       ...
   }
   

Starting from Java 7:

Define a path and the String containing the line separator at the beginning:

Path p = Paths.get("C:\\Users\\first.last\\test.txt");
String s = System.lineSeparator() + "New Line!";

and then you can use one of the following approaches:

1. Using Files.write (small files):

   try {
       Files.write(p, s.getBytes(), StandardOpenOption.APPEND);
   } catch (IOException e) {
       System.err.println(e);
   }
   

2. Using Files.newBufferedWriter(text files):

   try (BufferedWriter writer = Files.newBufferedWriter(p, StandardOpenOption.APPEND)) {
       writer.write(s);
   } catch (IOException ioe) {
       System.err.format("IOException: %s%n", ioe);
   }
   

3. Using Files.newOutputStream (interoperable with java.io APIs):

   try (OutputStream out = new BufferedOutputStream(Files.newOutputStream(p, StandardOpenOption.APPEND))) {
       out.write(s.getBytes());
   } catch (IOException e) {
       System.err.println(e);
   }
   

4. Using Files.newByteChannel (random access files):

   try (SeekableByteChannel sbc = Files.newByteChannel(p, StandardOpenOption.APPEND)) {
       sbc.write(ByteBuffer.wrap(s.getBytes()));
   } catch (IOException e) {
       System.err.println(e);
   }
   

5. Using FileChannel.open (random access files):

   try (FileChannel sbc = FileChannel.open(p, StandardOpenOption.APPEND)) {
       sbc.write(ByteBuffer.wrap(s.getBytes()));
   } catch (IOException e) {
       System.err.println(e);
   }
   

Details about these methods can be found in the Oracle's tutorial.

layout.setBackgroundResource(R.drawable.ready); is correct.
Another way to achieve it is to use the following:

final int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    layout.setBackgroundDrawable(ContextCompat.getDrawable(context, R.drawable.ready) );
} else {
    layout.setBackground(ContextCompat.getDrawable(context, R.drawable.ready));
}

But I think the problem occur because you are trying to load big images.
Here is a good tutorial how to load large bitmaps.

UPDATE:
getDrawable(int ) deprecated in API level 22

getDrawable(int ) is now deprecated in API level 22. You should use the following code from the support library instead:

ContextCompat.getDrawable(context, R.drawable.ready)

If you refer to the source code of ContextCompat.getDrawable, it gives you something like this:

/**
 * Return a drawable object associated with a particular resource ID.
 * <p>
 * Starting in {@link android.os.Build.VERSION_CODES#LOLLIPOP}, the returned
 * drawable will be styled for the specified Context's theme.
 *
 * @param id The desired resource identifier, as generated by the aapt tool.
 *            This integer encodes the package, type, and resource entry.
 *            The value 0 is an invalid identifier.
 * @return Drawable An object that can be used to draw this resource.
 */
public static final Drawable getDrawable(Context context, int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 21) {
        return ContextCompatApi21.getDrawable(context, id);
    } else {
        return context.getResources().getDrawable(id);
    }
}

More details on ContextCompat

As of API 22, you should use the getDrawable(int, Theme) method instead of getDrawable(int).

UPDATE:
If you are using the support v4 library, the following will be enough for all versions.

ContextCompat.getDrawable(context, R.drawable.ready)

You will need to add the following in your app build.gradle

compile 'com.android.support:support-v4:23.0.0' # or any version above

Or using ResourceCompat, in any API like below:

import android.support.v4.content.res.ResourcesCompat;
ResourcesCompat.getDrawable(getResources(), R.drawable.name_of_drawable, null);

Yes, you can use regular expressions in C#.

Using regular expressions with C#:

using System.Text.RegularExpressions;

string your_String = "Hello@Hello&Hello(Hello)";
string my_String =  Regex.Replace(your_String, @"[^0-9a-zA-Z]+", ",");

There is a bug introduced in 2.6, and affects to 2.7 as well

The upsert used to work correctly on 2.4

https://groups.google.com/forum/#!topic/mongodb-user/UcKvx4p4hnY https://jira.mongodb.org/browse/SERVER-13843

Take a look, it contains some important info

UPDATED:

It doesnt mean upsert does not work. Here is a nice example of how to use it:

User.findByIdAndUpdate(userId, {online: true, $setOnInsert: {username: username, friends: []}}, {upsert: true})
    .populate('friends')
    .exec(function (err, user) {
        if (err) throw err;
        console.log(user);

        // Emit load event

        socket.emit('load', user);
    });

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z] or [0-9-]), OR escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.

(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Great question!

an alternative would be to do something like:

SELECT
   CAST(P0.seconds as bigint) as seconds
FROM
   (
   SELECT
      seconds
   FROM
      TableName
   WHERE
      ISNUMERIC(seconds) = 1
   ) P0

If you just need to do it one-off, navigate to chrome://extensions. Enable Developer Mode at upper right. The ID will be shown in the box for each extension.

Or, if you're working on developing a userscript or extension, purposefully throw an error. Look in the javascript console, and the ID will be there, on the right side of the console, in the line describing the error.

Lastly, you can look in your chrome extensions directory; it stores extensions in directories named by the ID. This is the worst choice, as you'd have extension IDs, and have to read each manifest.json to figure out which ID was the right one. But if you just installed something, you can also just sort by creation date, and the newest extension directory will be the ID you want.

Not really an answer to your question as asked, but thought I'd chip in about your general objective.

There already is a method to generate random file names in .NET.

See System.Path.GetTempFileName and GetRandomFileName.

Alternatively, it is a common practice to use a GUID to name random files.

Here is a solution that creates a section that is expandable using somewhat material design, bootstrap 4.5/5 alpha and entirely non-javascript.

Writing the properties file with multiple comments is not supported. Why ?

PropertyFile.java

public class PropertyFile extends Task {

    /* ========================================================================
     *
     * Instance variables.
     */

    // Use this to prepend a message to the properties file
    private String              comment;

    private Properties          properties;

The ant property file task is backed by a java.util.Properties class which stores comments using the store() method. Only one comment is taken from the task and that is passed on to the Properties class to save into the file.

The way to get around this is to write your own task that is backed by commons properties instead of java.util.Properties. The commons properties file is backed by a property layout which allows settings comments for individual keys in the properties file. Save the properties file with the save() method and modify the new task to accept multiple comments through <comment> elements.

I would use os.chdir like this:

os.chdir("/path/to/change/to")

By the way, if you need to figure out your current path, use os.getcwd().

background is shorthand property for the following:

 - background-color
 - background-image
 - background-repeat
 - background-attachment
 - background-position

You can detailed info on every property here

Properties order

In most of browser implementation (i think maybe older browser could present issues) the order of the properties does not matter, except for:

• background-origin and background-clip: when both of this properties are present, the first one refer to -origin and the second to -clip.

  Example:

  background: content-box green padding-box;
  

  Is equivalent to:

  background-origin: content-box;
  background-color: green;
  background-clip: padding-box;
  

• background-size must always follow background-position and the properties must be separated by /

• if background-position is composed by two numbers, the first one is the horizontal value and the second the vertical value.

The major difference between Spring MVC and Struts is: Spring MVC is loosely coupled framework whereas Struts is tightly coupled. For enterprise Application you need to build your application as loosely coupled as it would make your application more reusable and robust as well as distributed.

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

you will almost never get these codes in practice so this code is pretty much pointless

What is your reason for excluding all transitive dependencies?

If there is a particular artifact (such as commons-logging) which you need to exclude from every dependency, the Version 99 Does Not Exist approach might help.

Update 2012: Don't use this approach. Use maven-enforcer-plugin and exclusions. Version 99 produces bogus dependencies and the Version 99 repository is offline (there are similar mirrors but you can't rely on them to stay online forever either; it's best to use only Maven Central).

You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ] will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ].
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)

In your case, I would use shell form

ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"

For 'replacement' of deprecated ActionBar, I changed the type of my ActionBar-type variables to PagerTabStrip, as per (old code in comment):

// ActionBar bigActionBar;
PagerTabStrip bigActionBar;

A 'replacement' for ~actionBar's .selectTab(tabindex) was to use my associated ViewPager's .setCurrentItem(int) method, like this (old code in comment):

/*
ActionBar.Tab eventTab = bigActionBar.getTabAt(2);
bigActionBar.selectTab(eventTab);
*/
mViewPager.setCurrentItem(2);

Hope this is helpful.

An alternative for the bind() method.

Use the click() method, do something like this:

commentbtn.click({id: 10, name: "João"}, onClickCommentBtn);

function onClickCommentBtn(event)
{
  alert("Id=" + event.data.id + ", Name = " + event.data.name);
}

Or, if you prefer:

commentbtn.click({id: 10, name: "João"},  function (event) {
  alert("Id=" + event.data.id + ", Nome = " + event.data.name);
});

It will show an alert box with the following infos:

Id = 10, Name = João

In your web.config (on the server) add

<system.diagnostics>
 <sources>
  <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
   <listeners>
    <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="C:\logs\Traces.svclog"/>
   </listeners>
  </source>
 </sources>
</system.diagnostics>

enctype='multipart/form-data is an encoding type that allows files to be sent through a POST. Quite simply, without this encoding the files cannot be sent through POST.

If you want to allow a user to upload a file via a form, you must use this enctype.

If you only want to change the font in the TEXTAREA then you only need to change the changeFont() function in the original code to:

function changeFont(_name) {
    document.getElementById("mytextarea").style.fontFamily = _name;
}

Then selecting a font will change on the font only in the TEXTAREA.

A call to Class#getResourceAsStream(String) delegates to the class loader and the resource is searched in the class path. In other words, you current code won't work and you should put abc.txt in WEB-INF/classes, or in WEB-INF/lib if packaged in a jar file.

Or use ServletContext.getResourceAsStream(String) which allows servlet containers to make a resource available to a servlet from any location, without using a class loader. So use this from a Servlet:

this.getServletContext().getResourceAsStream("/WEB-INF/abc.txt") ;

But is there a way I can call getServletContext from my Web Service?

If you are using JAX-WS, then you can get a WebServiceContext injected:

@Resource
private WebServiceContext wsContext;

And then get the ServletContext from it:

ServletContext sContext= wsContext.getMessageContext()
                             .get(MessageContext.SERVLET_CONTEXT));

You can use the output value from stat_summary()

ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) 
+ geom_boxplot() 
+ stat_summary(fun.y=mean, colour="darkred", geom="point", hape=18, size=3,show_guide = FALSE)
+ stat_summary(fun.y=mean, colour="red", geom="text", show_guide = FALSE, 
               vjust=-0.7, aes( label=round(..y.., digits=1)))

If you are running in Android 29 then you have to use scoped storage or for now, you can bypass this issue by using:

android:requestLegacyExternalStorage="true"

in manifest in the application tag.

The reason not to use ICloneable is not because it doesn't have a generic interface. The reason not to use it is because it's vague. It doesn't make clear whether you're getting a shallow or a deep copy; that's up to the implementer.

Yes, MemberwiseClone makes a shallow copy, but the opposite of MemberwiseClone isn't Clone; it would be, perhaps, DeepClone, which doesn't exist. When you use an object through its ICloneable interface, you can't know which kind of cloning the underlying object performs. (And XML comments won't make it clear, because you'll get the interface comments rather than the ones on the object's Clone method.)

What I usually do is simply make a Copy method that does exactly what I want.

Pass by pointer is the only way you could pass "by reference" in C, so you still see it used quite a bit.

The NULL pointer is a handy convention for saying a parameter is unused or not valid, so use a pointer in that case.

References can't be updated once they're set, so use a pointer if you ever need to reassign it.

Prefer a reference in every case where there isn't a good reason not to. Make it const if you can.

In my case the only way I could keep using GetGroups() without any expcetion was adding the user (USER_WITH_PERMISSION) to the group which has permission to read the AD (Active Directory). It's extremely essential to construct the PrincipalContext passing this user and password.

var pc = new PrincipalContext(ContextType.Domain, domain, "USER_WITH_PERMISSION", "PASS");
var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, userName);
var groups = user.GetGroups();

Steps you may follow inside Active Directory to get it working:

1. Into Active Directory create a group (or take one) and under secutiry tab add "Windows Authorization Access Group"
2. Click on "Advanced" button
3. Select "Windows Authorization Access Group" and click on "View"
4. Check "Read tokenGroupsGlobalAndUniversal"
5. Locate the desired user and add to the group you created (taken) from the first step

If you can create a numbers table, that contains numbers from 1 to the maximum fields to split, you could use a solution like this:

select
  tablename.id,
  SUBSTRING_INDEX(SUBSTRING_INDEX(tablename.name, ',', numbers.n), ',', -1) name
from
  numbers inner join tablename
  on CHAR_LENGTH(tablename.name)
     -CHAR_LENGTH(REPLACE(tablename.name, ',', ''))>=numbers.n-1
order by
  id, n

Please see fiddle here.

If you cannot create a table, then a solution can be this:

select
  tablename.id,
  SUBSTRING_INDEX(SUBSTRING_INDEX(tablename.name, ',', numbers.n), ',', -1) name
from
  (select 1 n union all
   select 2 union all select 3 union all
   select 4 union all select 5) numbers INNER JOIN tablename
  on CHAR_LENGTH(tablename.name)
     -CHAR_LENGTH(REPLACE(tablename.name, ',', ''))>=numbers.n-1
order by
  id, n

an example fiddle is here.

I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).

What I did to get this working on my machine is to:

• followed instructions on Oracle JDK7 Mac OS X Port for general installation
• in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
• select Platform Settings > SDKs, press "+" (plus) sign to add new SDK
• select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from "lib" directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
• you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)

It is bad practice to perform network operations on the main thread, which is why you are seeing the NetworkOnMainThreadException. It is prevented by the policy. If you really must do it for testing, put the following in your OnCreate:

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
 StrictMode.setThreadPolicy(policy); 

Please remember that is is very bad practice to do this, and should ideally move your network code to an AsyncTask or a Thread.

Yes, it is important if your item will be used as a key in a dictionary, or HashSet<T>, etc - since this is used (in the absence of a custom IEqualityComparer<T>) to group items into buckets. If the hash-code for two items does not match, they may never be considered equal (Equals will simply never be called).

The GetHashCode() method should reflect the Equals logic; the rules are:

• if two things are equal (Equals(...) == true) then they must return the same value for GetHashCode()
• if the GetHashCode() is equal, it is not necessary for them to be the same; this is a collision, and Equals will be called to see if it is a real equality or not.

In this case, it looks like "return FooId;" is a suitable GetHashCode() implementation. If you are testing multiple properties, it is common to combine them using code like below, to reduce diagonal collisions (i.e. so that new Foo(3,5) has a different hash-code to new Foo(5,3)):

unchecked // only needed if you're compiling with arithmetic checks enabled
{ // (the default compiler behaviour is *disabled*, so most folks won't need this)
    int hash = 13;
    hash = (hash * 7) + field1.GetHashCode();
    hash = (hash * 7) + field2.GetHashCode();
    ...
    return hash;
}

Oh - for convenience, you might also consider providing == and != operators when overriding Equals and GetHashCode.

A demonstration of what happens when you get this wrong is here.

Simply like that:

arr.join("")

I worked a little with RecyclerView and still prefer ListView.

1. Sure, both of them use ViewHolders, so this is not an advantage.

2. A RecyclerView is more difficult in coding.

3. A RecyclerView doesn't contain a header and footer, so it's a minus.

4. A ListView doesn't require to make a ViewHolder. In cases where you want to have a list with sections or subheaders it would be a good idea to make independent items (without a ViewHolder), it's easier and doesn't require separate classes.

From Git documentation starting from version 2.0:

To add content for the whole tree, run:

git add --all :/

or

git add -A :/

To restrict the command to the current directory, run:

git add --all .

or

git add -A .

I solved the same problem following this example:

This example uses the jQuery JavaScript library.

First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML :

<img src="/images/loading.gif" id="loading-indicator" style="display:none" />

And the following to your CSS file:

#loading-indicator {
  position: absolute;
  left: 10px;
  top: 10px;
}

Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:

$(document).ajaxSend(function(event, request, settings) {
    $('#loading-indicator').show();
});

$(document).ajaxComplete(function(event, request, settings) {
    $('#loading-indicator').hide();
});

This solution is from the following link. How to display an animated icon during Ajax request processing

As an echo to @Bactisme's response, the way one would go about retrieving the current timestamp (in milliseconds, for example) is:

msec := time.Now().UnixNano() / 1000000

Resource: https://gobyexample.com/epoch

first up on create your jsp file : and write the text field which you want
for ex:

after that create your servlet class:

public class test{

protected void doGet(paramter , paramter){

String name  = request.getparameter("name");
 }

}

bellow are cause above “org.xml.sax.SAXParseException: Content is not allowed in prolog” exception.

1. First check the file path of schema.xsd and file.xml.
2. The encoding in your XML and XSD (or DTD) should be same.
   XML file header: <?xml version='1.0' encoding='utf-8'?>
   XSD file header: <?xml version='1.0' encoding='utf-8'?>
3. if anything comes before the XML document type declaration.i.e: hello<?xml version='1.0' encoding='utf-16'?>

        <table id="table_id" class="table table-hover">
          <thead>
            <tr>
             ...
             ...
            </tr>
          </thead>
        </table>

use this command to clear the body of that table: $("#table_id tbody").empty()

I use jquery to load the table content dynamically, and use this command to clear the body when doing the refreshing.

hope this helps you.

As I understand, you want the average value for each id at each pass. The solution is

SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;

defaultOrder contain a array where key is a column name and value is a SORT_DESC or SORT_ASC that's why below code not working.

$dataProvider = new ActiveDataProvider([
        'query' => $query,
        'sort' => ['defaultOrder'=>'topic_order asc']
    ]);

Correct Way

$dataProvider = new ActiveDataProvider([
    'query' => $query,
    'sort' => [
        'defaultOrder' => [
            'topic_order' => SORT_ASC,
        ]
    ],
]);

Note: If a query already specifies the orderBy clause, the new ordering instructions given by end users (through the sort configuration) will be appended to the existing orderBy clause. Any existing limit and offset clauses will be overwritten by the pagination request from end users (through the pagination configuration).

You can detail learn from Yii2 Guide of Data Provider

Sorting By passing Sort object in query

 $sort = new Sort([
        'attributes' => [
            'age',
            'name' => [
                'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
                'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
                'default' => SORT_DESC,
                'label' => 'Name',
            ],
        ],
    ]);

    $models = Article::find()
        ->where(['status' => 1])
        ->orderBy($sort->orders)
        ->all();

"What does if __name__==“__main__”: do?" has already been answered.

Having a main() function allows you to call its functionality if you import the module. The main (no pun intended) benefit of this (IMHO) is that you can unit test it.

A very simple method would be to use the extract method to select all the digits. Simply supply it the regular expression '\d+' which extracts any number of digits.

df['result'] = df.result.str.extract(r'(\d+)', expand=True).astype(int)
df

    time  result
1  09:00      52
2  10:00      62
3  11:00      44
4  12:00      30
5  13:00     110

Note: dplyr now contains the distinct function for this purpose.

Original answer below:

library(dplyr)
set.seed(123)
df <- data.frame(
  x = sample(0:1, 10, replace = T),
  y = sample(0:1, 10, replace = T),
  z = 1:10
)

One approach would be to group, and then only keep the first row:

df %>% group_by(x, y) %>% filter(row_number(z) == 1)

## Source: local data frame [3 x 3]
## Groups: x, y
## 
##   x y z
## 1 0 1 1
## 2 1 0 2
## 3 1 1 4

(In dplyr 0.2 you won't need the dummy z variable and will just be able to write row_number() == 1)

I've also been thinking about adding a slice() function that would work like:

df %>% group_by(x, y) %>% slice(from = 1, to = 1)

Or maybe a variation of unique() that would let you select which variables to use:

df %>% unique(x, y)

This originally answered a supplemental question about the wisdom of downloading jQuery versus accessing it via a CDN, which is no longer present...

To answer the thing about Google. I have moved over to accessing JQuery and most other of these sorts of libraries via the corresponding CDN in my sites.

As more people do this means that it's more likely to be cached on user's machines, so my vote goes for good idea.

In the five years since I first offered this, it has become common wisdom.

SET foreign_key_checks = 0; DELETE FROM yourtable; SET foreign_key_checks = 1;

(Updated - Thanks to the people who commented)

Modern Versions of PostgreSQL

Suppose you have a table named test1, to which you want to add an auto-incrementing, primary-key id (surrogate) column. The following command should be sufficient in recent versions of PostgreSQL:

   ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

Older Versions of PostgreSQL

In old versions of PostgreSQL (prior to 8.x?) you had to do all the dirty work. The following sequence of commands should do the trick:

  ALTER TABLE test1 ADD COLUMN id INTEGER;
  CREATE SEQUENCE test_id_seq OWNED BY test1.id;
  ALTER TABLE test ALTER COLUMN id SET DEFAULT nextval('test_id_seq');
  UPDATE test1 SET id = nextval('test_id_seq');

Again, in recent versions of Postgres this is roughly equivalent to the single command above.

change User Account Control setting via control panel

step 1 -: Go to control panel

step 2-: select 'user Accounts'

step 3-: select 'User Accounts' (Control Panel\User Accounts\User Accounts)

step 4 -: select 'Change User Account Control settings'

step 5 -: Drag the slider down to Never notify and after click ok.

pgcrypto Extension

As of Postgres 9.4, the pgcrypto module includes the gen_random_uuid() function. This function generates one of the random-number based Version 4 type of UUID.

Get contrib modules, if not already available.

sudo apt-get install postgresql-contrib-9.4

Use pgcrypto module.

CREATE EXTENSION "pgcrypto";

The gen_random_uuid() function should now available;

Example usage.

INSERT INTO items VALUES( gen_random_uuid(), 54.321, 31, 'desc 1', 31.94 ) ;

Quote from Postgres doc on uuid-ossp module.

Note: If you only need randomly-generated (version 4) UUIDs, consider using the gen_random_uuid() function from the pgcrypto module instead.

You can use the commandArgs function to get all the options that were passed by Rscript to the actual R interpreter and search them for --file=. If your script was launched from the path or if it was launched with a full path, the script.name below will start with a '/'. Otherwise, it must be relative to the cwd and you can concat the two paths to get the full path.

Edit: it sounds like you'd only need the script.name above and to strip off the final component of the path. I've removed the unneeded cwd() sample and cleaned up the main script and posted my other.R. Just save off this script and the other.R script into the same directory, chmod +x them, and run the main script.

main.R:

#!/usr/bin/env Rscript
initial.options <- commandArgs(trailingOnly = FALSE)
file.arg.name <- "--file="
script.name <- sub(file.arg.name, "", initial.options[grep(file.arg.name, initial.options)])
script.basename <- dirname(script.name)
other.name <- file.path(script.basename, "other.R")
print(paste("Sourcing",other.name,"from",script.name))
source(other.name)

other.R:

print("hello")

output:

burner@firefighter:~$ main.R
[1] "Sourcing /home/burner/bin/other.R from /home/burner/bin/main.R"
[1] "hello"
burner@firefighter:~$ bin/main.R
[1] "Sourcing bin/other.R from bin/main.R"
[1] "hello"
burner@firefighter:~$ cd bin
burner@firefighter:~/bin$ main.R
[1] "Sourcing ./other.R from ./main.R"
[1] "hello"

This is what I believe dehmann is looking for.

Otherwise you prob want the get method:

Load a new web page in the current browser window. This is done using an
HTTP GET operation, and the method will block until the load is complete.

Navigate allows you to work with browser history as far as i understand it.

It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.

As none of these approaches worked for me, I simply did a:

mysqldump [...] | grep -v "LOCK TABLE" | mysql [...]

It will exclude both LOCK TABLE <x> and UNLOCK TABLES commands.

Note: Hopefully your data doesn't contain that string in it!

In Django 3.x, the accepted answer won't work because render_to_response has been removed completely as well as some more changes have been made since the version the accepted answer worked for.

Some other answers are also there but I'm presenting a little cleaner answer:

In your main urls.py file:

handler404 = 'yourapp.views.handler404'
handler500 = 'yourapp.views.handler500'

In yourapp/views.py file:

def handler404(request, exception):
    context = {}
    response = render(request, "pages/errors/404.html", context=context)
    response.status_code = 404
    return response


def handler500(request):
    context = {}
    response = render(request, "pages/errors/500.html", context=context)
    response.status_code = 500
    return response

Ensure that you have imported render() in yourapp/views.py file:

from django.shortcuts import render

Side note: render_to_response() was deprecated in Django 2.x and it has been completely removed in verision 3.x.

If you set the cookie to expire in the past, the browser will remove it. See setcookie() delete example at php.net

Simply drag a ContextMenu or ContextMenuStrip component into your form and visually design it, then assign it to the ContextMenu or ContextMenuStrip property of your desired control.

You can add to the system-path at runtime:

import sys
sys.path.insert(0, 'path/to/your/py_file')

import py_file

This is by far the easiest way to do it.

Well I can see two solutions here:

1) Follow the Docs-Tkinter install for Python (for Windows):

Tkinter (and, since Python 3.1, ttk) are included with all standard Python distributions. It is important that you use a version of Python supporting Tk 8.5 or greater, and ttk. We recommend installing the "ActivePython" distribution from ActiveState, which includes everything you'll need.

In your web browser, go to Activestate.com, and follow along the links to download the Community Edition of ActivePython for Windows. Make sure you're downloading a 3.1 or newer version, not a 2.x version.

Run the installer, and follow along. You'll end up with a fresh install of ActivePython, located in, e.g. C:\python32. From a Windows command prompt, or the Start Menu's "Run..." command, you should then be able to run a Python shell via:

% C:\python32\python

This should give you the Python command prompt. From the prompt, enter these two commands:

>>> import tkinter
>>> tkinter._test()

This should pop up a small window; the first line at the top of the window should say "This is Tcl/Tk version 8.5"; make sure it is not 8.4!

2) Uninstall 64-bit Python and install 32 bit Python.

You can try this

 SELECT tbl.* FROM (SELECT * FROM table ORDER BY timestamp DESC) as tbl
 GROUP BY tbl.m_id  

Sort and Lock Table is the only solution I have seen which does work on other browsers than IE. (although this "locked column css" might do the trick as well). Required code block below.

Generic Table Sort

Basic Concept: A table can be sorted by clicking on the title of any
column in the table, toggling between ascending and descending sorts.


Assumptions:

* The first row of the table contains column titles that are "clicked"
  to sort the table

* The images 'desc.gif','asc.gif','none.gif','sorting.gif' exist

* The img tag is in each column of the the title row to represent the
  sort graphic.

* The CSS classes 'alternateRow' and 'sortedColumn' exist so we can
  have alternating colors for each row and a highlight the sorted
  column.  Something like the <style> definition below, but with the
  background colors set to whatever you want.

   <style>
   tr.alternateRow {
     background-color: #E0F1E0;
   }

   td.sortedColumn {
     background-color: #E0F1E0;
   }

   tr.alternateRow td.sortedColumn {
     background-color: #c5e5c5;
   }
   </style>

ADD go /usr/local/

will copy the contents of your local go directory in the /usr/local/ directory of your docker image.

To copy the go directory itself in /usr/local/ use:

ADD go /usr/local/go

or

COPY go /usr/local/go

i Change the format of file to *.XLSX this change compress my file and reduce file size of 15%

If you use an observable instead of a primitive value, the select will not raise change events on initial binding. You can continue to bind to the change event, rather than subscribing directly to the observable.

In case this happens to someone. I built my own library to use with a third party code. While I was building it to deliver, I accidentally left my iPhone 4S plugged in, and so Xcode built my library only for the plugged architecture instead of following the project settings. Remove any plugged in devices and rebuilt the library, link it, and you should be all right.

Hope it helps.

It's my code: Work for me

 var jsonData = request.body;
    var jsonParsed = JSON.parse(JSON.stringify(jsonData));

    // message_body = {
    //   "phone": "5511995001920",
    //   "body": "WhatsApp API on chat-api.com works good"
    // }

    axios.post(whatsapp_url, jsonParsed,validateStatus = true)
    .then((res) => {
      // console.log(`statusCode: ${res.statusCode}`)

            console.log(res.data)
        console.log(res.status);

        // var jsonData = res.body;
        // var jsonParsed = JSON.parse(JSON.stringify(jsonData));

        response.json("ok")
    })
    .catch((error) => {
      console.error(error)
        response.json("error")
    })

Try this:

SELECT * 
  FROM  (
        SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast 
        FROM users 
    ) a
WHERE firstlast = "Bob Michael Jones"

If your model is really "responsible" for the constants you should stick them there. You can create class methods to access them without creating a new object instance:

class Card < ActiveRecord::Base
  def self.colours
    ['white', 'blue']
  end
end

# accessible like this
Card.colours

Alternatively, you can create class variables and an accessor. This is however discouraged as class variables might act kind of surprising with inheritance and in multi-thread environments.

class Card < ActiveRecord::Base
  @@colours = ['white', 'blue'].freeze
  cattr_reader :colours
end

# accessible the same as above
Card.colours

The two options above allow you to change the returned array on each invocation of the accessor method if required. If you have true a truly unchangeable constant, you can also define it on the model class:

class Card < ActiveRecord::Base
  COLOURS = ['white', 'blue'].freeze
end

# accessible as
Card::COLOURS

You could also create global constants which are accessible from everywhere in an initializer like in the following example. This is probably the best place, if your colours are really global and used in more than one model context.

# put this into config/initializers/my_constants.rb
COLOURS = ['white', 'blue'].freeze

# accessible as a top-level constant this time
COLOURS

Note: when we define constants above, often we want to freeze the array. That prevents other code from later (inadvertently) modifying the array by e.g. adding a new element. Once an object is frozen, it can't be changed anymore.

If your project has a CMake configuration it's pretty straight forward to setup VSCode, e.g. setup tasks.json like below:

{
    "version": "0.1.0",
    "command": "sh",
    "isShellCommand": true,
    "args": ["-c"],
    "showOutput": "always",
    "suppressTaskName": true,
    "options": {
        "cwd": "${workspaceRoot}/build"
    },
    "tasks": [
        {
            "taskName": "cmake",
            "args": ["cmake ."]
        },
        {
            "taskName": "make",
            "args" : ["make"],
            "isBuildCommand": true,
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": "absolute",
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

This assumes that there is a folder build in the root of the workspace with a CMake configuration.

There's also a CMake integration extension that adds a "CMake build" command to VScode.

PS! The problemMatcher is setup for clang-builds. To use GCC I believe you need to change fileLocation to relative, but I haven't tested this.

Try this:

try
{
    throw new InvalidEmployeeTypeException();
    input.nextLine();
}
catch(InvalidEmployeeTypeException ex)
{
      //do error handling
}

continue;

the task is: get ?and? remove element from list

p.stream().collect( Collectors.collectingAndThen( Collector.of(
    ArrayDeque::new,
    (a, producer) -> {
      if( producer.getPod().equals( pod ) )
        a.addLast( producer );
    },
    (a1, a2) -> {
      return( a1 );
    },
    rslt -> rslt.pollFirst()
  ),
  (e) -> {
    if( e != null )
      p.remove( e );  // remove
    return( e );    // get
  } ) );

Little unrelated but I will still put it here, For other practical purposes shell variables can be used as -

value=10
jq  '."key" = "'"$value"'"' file.json

<%# (string)Eval("gender") =="M" ? "Male" :"Female"%>

How to delete only the content of file in python

There is several ways of set the logical size of a file to 0, depending how you access that file:

To empty an open file:

def deleteContent(pfile):
    pfile.seek(0)
    pfile.truncate()

To empty a open file whose file descriptor is known:

def deleteContent(fd):
    os.ftruncate(fd, 0)
    os.lseek(fd, 0, os.SEEK_SET)

To empty a closed file (whose name is known)

def deleteContent(fName):
    with open(fName, "w"):
        pass

I have a temporary file with some content [...] I need to reuse that file

That being said, in the general case it is probably not efficient nor desirable to reuse a temporary file. Unless you have very specific needs, you should think about using tempfile.TemporaryFile and a context manager to almost transparently create/use/delete your temporary files:

import tempfile

with tempfile.TemporaryFile() as temp:
     # do whatever you want with `temp`

# <- `tempfile` guarantees the file being both closed *and* deleted
#     on exit of the context manager

We can also use

return $this->db->count_all('table_name');  

or

$this->db->from('table_name');
return $this->db->count_all_result();

or

return $this->db->count_all_result('table_name');

or

$query = $this->db->query('select * from tab');  
return $query->num_rows();

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

You can do this simply Mysql DATE_FORMAT() function in GROUP BY. You may want to add an extra column for added clarity in some cases such as where records span several years then same month occurs in different years.Here so many option you can customize this. Please read this befor starting. Hope it should be very helpful for you. Here is sample query for your understanding

SELECT
    COUNT(id),
    DATE_FORMAT(record_date, '%Y-%m-%d') AS DAY,
    DATE_FORMAT(record_date, '%Y-%m') AS MONTH,
    DATE_FORMAT(record_date, '%Y') AS YEAR

FROM
    stats
WHERE
    YEAR = 2009
GROUP BY
    DATE_FORMAT(record_date, '%Y-%m-%d ');

Enjoy this :) Without cast each value individually.

SELECT ...,
  IsCoursedBased = CAST(
      CASE WHEN fc.CourseId is not null THEN 1 ELSE 0 END
    AS BIT
  )
FROM fc

Anyone can use underscore _ (its Okay)

No one should use hypen - (its Bad practice)

No one should use capital letters inside package names (Bad practice)

NOTE: Here "Bad Practice" is meant for technically you are allowed to use that, but conventionally its not in good manners to write.

How do I check whether a file exists, without using the try statement?

In 2016, this is still arguably the easiest way to check if both a file exists and if it is a file:

import os
os.path.isfile('./file.txt')    # Returns True if exists, else False

isfile is actually just a helper method that internally uses os.stat and stat.S_ISREG(mode) underneath. This os.stat is a lower-level method that will provide you with detailed information about files, directories, sockets, buffers, and more. More about os.stat here

Note: However, this approach will not lock the file in any way and therefore your code can become vulnerable to "time of check to time of use" (TOCTTOU) bugs.

So raising exceptions is considered to be an acceptable, and Pythonic, approach for flow control in your program. And one should consider handling missing files with IOErrors, rather than if statements (just an advice).

Use:

ImageView image = (ImageView) findViewById(R.id.image);
image.setAlpha(150); // Value: [0-255]. Where 0 is fully transparent
                     // and 255 is fully opaque. Set the value according
                     // to your choice, and you can also use seekbar to
                     // maintain the transparency.

Run a jar file and specify a class path like this:

java -cp <jar_name.jar:libs/*> com.test.App

jar_name.jar is the full name of the JAR you want to execute

libs/* is a path to your dependency JARs

com.test.App is the fully qualified name of the class from the JAR that has the main(String[]) method

The jar and dependent jar should have execute permissions.

Your select statement is returning a sequence of anonymous type , not a sequence of DataRows. CopyToDataTable() is only available on IEnumerable<T> where T is or derives from DataRow. You can select r the row object to call CopyToDataTable on it.

var query = from r in matrix.AsEnumerable()
                where r.Field<string>("c_to") == c_to &&
                      r.Field<string>("p_to") == p_to
                 select r;

DataTable conversions = query.CopyToDataTable();

You can also implement CopyToDataTable Where the Generic Type T Is Not a DataRow.

I think my code (tested) is more "educated", assuming the simpler the better.

'Function to sort an array decscending
Function SORT(Rango As Range) As Variant
    Dim check As Boolean
    check = True

Be careful if you have spaces in your string variables and you check for existence. Be sure to quote them properly.

if [ ! "${somepath}" ] || [ ! "${otherstring}" ] || [ ! "${barstring}" ] ; then

You can use iconSize like this:

    floatingActionButton: FloatingActionButton(
      onPressed: () {
        // Add your onPressed code here
      },
      child: IconButton(
        icon: isPlaying
            ? Icon(
                Icons.pause_circle_outline,
              )
            : Icon(
                Icons.play_circle_outline,
              ),
              iconSize: 40,
              
        onPressed: () {
          setState(() {
            isPlaying = !isPlaying;
          });
        },
       
      ),
    ),

Make the div of id="childdivimag" a span instead, and wrap that in an a element. As the span and img are in-line elements by default this remains valid, whereas a div is a block level element, and therefore invalid mark-up when contained within an a.

You were right regarding how you want to generate salt i.e. its nothing but a random number. For this particular case it would protect your system from possible Dictionary attacks. Now, for the second problem what you could do is instead of using UTF-8 encoding you may want to use Base64. Here, is a sample for generating a hash. I am using Apache Common Codecs for doing the base64 encoding you may select one of your own

public byte[] generateSalt() {
        SecureRandom random = new SecureRandom();
        byte bytes[] = new byte[20];
        random.nextBytes(bytes);
        return bytes;
    }

public String bytetoString(byte[] input) {
        return org.apache.commons.codec.binary.Base64.encodeBase64String(input);
    }

public byte[] getHashWithSalt(String input, HashingTechqniue technique, byte[] salt) throws NoSuchAlgorithmException {
        MessageDigest digest = MessageDigest.getInstance(technique.value);
        digest.reset();
        digest.update(salt);
        byte[] hashedBytes = digest.digest(stringToByte(input));
        return hashedBytes;
    }
public byte[] stringToByte(String input) {
        if (Base64.isBase64(input)) {
            return Base64.decodeBase64(input);

        } else {
            return Base64.encodeBase64(input.getBytes());
        }
    }

Here is some additional reference of the standard practice in password hashing directly from OWASP

The JPA specification says the following about persist().

If X is a detached object, the EntityExistsException may be thrown when the persist operation is invoked, or the EntityExistsException or another PersistenceException may be thrown at flush or commit time.

So using persist() would be suitable when the object ought not to be a detached object. You might prefer to have the code throw the PersistenceException so it fails fast.

Although the specification is unclear, persist() might set the @GeneratedValue @Id for an object. merge() however must have an object with the @Id already generated.

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

Welcome to bash. It's an old, dark and mysterious thing, capable of great magic. :-)

The option you're asking about is for the find command though, not for bash. From your command line, you can man find to see the options.

The one you're looking for is -o for "or":

  list="$(find /home/user/Desktop -name '*.bmp' -o -name '*.txt')"

That said ... Don't do this. Storage like this may work for simple filenames, but as soon as you have to deal with special characters, like spaces and newlines, all bets are off. See ParsingLs for details.

$ touch 'one.txt' 'two three.txt' 'foo.bmp'
$ list="$(find . -name \*.txt -o -name \*.bmp -type f)"
$ for file in $list; do if [ ! -f "$file" ]; then echo "MISSING: $file"; fi; done
MISSING: ./two
MISSING: three.txt

Pathname expansion (globbing) provides a much better/safer way to keep track of files. Then you can also use bash arrays:

$ a=( *.txt *.bmp )
$ declare -p a
declare -a a=([0]="one.txt" [1]="two three.txt" [2]="foo.bmp")
$ for file in "${a[@]}"; do ls -l "$file"; done
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 one.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 two three.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 foo.bmp

The Bash FAQ has lots of other excellent tips about programming in bash.

Like the docs say, think about it this way. If you were to do an application like a book reader, you will not want to load all the fragments into memory at once. You would like to load and destroy Fragments as the user reads. In this case you will use FragmentStatePagerAdapter. If you are just displaying 3 "tabs" that do not contain a lot of heavy data (like Bitmaps), then FragmentPagerAdapter might suit you well. Also, keep in mind that ViewPager by default will load 3 fragments into memory. The first Adapter you mention might destroy View hierarchy and re load it when needed, the second Adapter only saves the state of the Fragment and completely destroys it, if the user then comes back to that page, the state is retrieved.

With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.

You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/

You can use DECIMAL or NUMERIC both are same

The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL, so the following remarks about DECIMAL apply equally to NUMERIC. : MySQL

i.e. DECIMAL(10,2)

Good read

You don't need complicated calculations. It can be done just by using OnGestureListener interface from GestureDetector class.

Inside onFling method you can detect all four directions like this:

MyGestureListener.java:

import android.util.Log;
import android.view.GestureDetector;
import android.view.MotionEvent;

public class MyGestureListener implements GestureDetector.OnGestureListener{

    private static final long VELOCITY_THRESHOLD = 3000;

    @Override
    public boolean onDown(final MotionEvent e){ return false; }

    @Override
    public void onShowPress(final MotionEvent e){ }

    @Override
    public boolean onSingleTapUp(final MotionEvent e){ return false; }

    @Override
    public boolean onScroll(final MotionEvent e1, final MotionEvent e2, final float distanceX,
                        final float distanceY){ return false; }

    @Override
    public void onLongPress(final MotionEvent e){ }

    @Override
    public boolean onFling(final MotionEvent e1, final MotionEvent e2,
                       final float velocityX,
                       final float velocityY){

        if(Math.abs(velocityX) < VELOCITY_THRESHOLD 
                    && Math.abs(velocityY) < VELOCITY_THRESHOLD){
            return false;//if the fling is not fast enough then it's just like drag
        }

        //if velocity in X direction is higher than velocity in Y direction,
        //then the fling is horizontal, else->vertical
        if(Math.abs(velocityX) > Math.abs(velocityY)){
            if(velocityX >= 0){
                Log.i("TAG", "swipe right");
            }else{//if velocityX is negative, then it's towards left
                Log.i("TAG", "swipe left");
            }
        }else{
            if(velocityY >= 0){
                Log.i("TAG", "swipe down");
            }else{
                Log.i("TAG", "swipe up");
            }
        }

        return true;
    }
}

usage:

GestureDetector mDetector = new GestureDetector(MainActivity.this, new MyGestureListener());

view.setOnTouchListener(new View.OnTouchListener(){
    @Override
    public boolean onTouch(final View v, final MotionEvent event){
        return mDetector.onTouchEvent(event);
    }
});

Set up a trap (you can trap several signals with one handler):

signal (SIGQUIT, my_handler);
signal (SIGINT, my_handler);

Handle the signal however you want, but be aware of limitations and gotchas:

void my_handler (int sig)
{
  /* Your code here. */
}

Are you referring to the server side or the client side?

For a client, you would want to adjust the sendTimeout attribute of a binding element. For a service, you would want to adjust the receiveTimeout attribute of a binding elemnent.

<system.serviceModel>
  <bindings>
    <netTcpBinding>
      <binding name="longTimeoutBinding"
        receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <security mode="None"/>
      </binding>
    </netTcpBinding>
  </bindings>

  <services>
    <service name="longTimeoutService"
      behaviorConfiguration="longTimeoutBehavior">
      <endpoint address="net.tcp://localhost/longtimeout/"
        binding="netTcpBinding" bindingConfiguration="longTimeoutBinding" />
    </service>
....

Of course, you have to map your desired endpoint to that particular binding.

To extend @hobbeshunter's answer if you want to take only index.html you can also use CopyPlugin, The main motivation to use this method over using other packages is because it's a nightmare to add many packages for every single type and config it etc. The easiest way is to use CopyPlugin for everything:

npm install copy-webpack-plugin --save-dev

Then

const CopyPlugin = require('copy-webpack-plugin');

module.exports = {
  plugins: [
    new CopyPlugin([
      { from: 'static', to: 'static' },
      { from: 'index.html', to: 'index.html', toType: 'file'},
    ]),
  ],

As you can see it copy the whole static folder along with all of it's content into dist folder. No css or file or any other plugins needed.

While this method doesn't suit for everything, it would get the job done simply & quickly.

Sample to execute an SQL string within the stored procedure:

(I'm using this to compare the number of entries on each table as first check for a regression test, within a cursor loop)

select @SqlQuery1 = N'select @CountResult1 = (select isnull(count(*),0) from ' + @DatabaseFirst+'.dbo.'+@ObjectName + ')'

execute sp_executesql    @SqlQuery1 , N'@CountResult1 int OUTPUT',     @CountResult1 = @CountResult1 output;

Before MySQL 5.7.6 this works from the command line:

mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('$w0rdf1sh');"

I don't have a mysql install to test on but I think in your case it would be

mysql -e "UPDATE mysql.user SET Password=PASSWORD('$w0rdf1sh') WHERE User='tate256';"

If you have installed, for example, php 5.4 it could be switched in the following way to php 5.5:

WCF = Windows Communication Foundation is used to build service-oriented applications. WPF = Windows Presentation Foundation is used to write platform-independent applications.

To fully comply with RSpec ~> 3.1 syntax and rubocop-rspec's default option for rule RSpec/MessageSpies, here's what you can do with spy:

Message expectations put an example's expectation at the start, before you've invoked the code-under-test. Many developers prefer using an arrange-act-assert (or given-when-then) pattern for structuring tests. Spies are an alternate type of test double that support this pattern by allowing you to expect that a message has been received after the fact, using have_received.

# arrange.
invitation = spy('invitation')

# act.
invitation.deliver("[email protected]")

# assert.
expect(invitation).to have_received(:deliver).with("[email protected]")

If you don't use rubocop-rspec or using non-default option. You may, of course, use RSpec 3 default with expect.

dbl = double("Some Collaborator")
expect(dbl).to receive(:foo).with("[email protected]")

Looks like PILlow may have changed tostring() to tobytes(). When trying to extract RGBA pixels to get them into an OpenGL texture, the following worked for me (within the glTexImage2D call which I omit for brevity).

from PIL import Image
img = Image.open("mandrill.png").rotate(180).transpose(Image.FLIP_LEFT_RIGHT)

# use img.convert("RGBA").tobytes() as texels

Hardware wise the Quadro and GeForce cards are often idential. Indeed it is sometimes possible to convert some models from GeForce into Quadro by simply uploading new firmware and changing a couple resistor jumpers.

The difference is in the intended market and hence cost.

Quadro cards are intended for CAD. High end CAD software still uses OpenGL, whereas games and lower end CAD software use Direct3D (aka DirectX).

Quadro cards simply have firmware that is optimised for OpenGL. In the early days OpenGL was better and faster than Direct3D but now there is little difference. Gaming cards only support a very limited set of OpenGL, hence they don't run it very well.

CAD companies, e.g. Dassault with SolidWorks actively push high end cards by offering no support for DirectX with any level of performance.

Other CAD companies such as Altium, with Altium Designer, made the decision that forcing their customers to buy more expensive cards is not worthwhile when Direct3D is as good (if not better these days) than OpenGL.

Because of the cost, there are often other differences in the hardware, such as less use of overclocking, more memory etc, but these have relatively minor effects compared with the firmware support.

The GroupBox has a Validated event for this purpose, if you are using WinForms.

private void grpBox_Validated(object sender, EventArgs e)
    {
        GroupBox g = sender as GroupBox;
        var a = from RadioButton r in g.Controls
                 where r.Checked == true select r.Name;
        strChecked = a.First();
     }

The original conio.h was implemented by Borland, so its not a part of the C Standard Library nor is defined by POSIX.

But here is an implementation for Linux that uses ncurses to do the job.

The following CSS will right-align both the arrow and the options:

select { text-align-last: right; }_x000D_
option { direction: rtl; }

<!-- example usage -->_x000D_
Choose one: <select>_x000D_
  <option>The first option</option>_x000D_
  <option>A second, fairly long option</option>_x000D_
  <option>Last</option>_x000D_
</select>

Inside the component, create a computed function

computed:{
  myState:function(){
    return this.$store.state.my_state; // return the state value in `my_state`
  }
}

Now the computed function name can be watched, like

watch:{
  myState:function(newVal,oldVal){
    // this function will trigger when ever the value of `my_state` changes
  }
}

The changes made in the vuex state my_state will reflect in the computed function myState and trigger the watch function.

If the state my_state is having nested data, then the handler option will help more

watch:{
  myState:{
    handler:function(newVal,oldVal){
      // this function will trigger when ever the value of `my_state` changes
    },
    deep:true
  }
}

This will watch all the nested values in the store my_state.

1.) Create a sequence of numbers 'seq' from 1 to 1000, and fix the width '-w' (width is determined by length of ending number, in this case 4 digits for 1000).

2.) Also, select which numbers you want using 'sed -n' (in this case, we select numbers 1-100).

3.) 'echo' out each number. Numbers are stored in the variable 'i', accessed using the '$'.

Pros: This code is pretty clean.

Cons: 'seq' isn't native to all Linux systems (as I understand)

for i in `seq -w 1 1000 | sed -n '1,100p'`; 
do 
    echo $i; 
done

{{ wpis.entry.lastChangeDate|date:"SHORT_DATETIME_FORMAT" }}

Adding to the accepted answer, I would say that implementing a correct multi producers / multi consumers queue is difficult (easier since C++11, though)

I would suggest you to try the (very good) lock free boost library, the "queue" structure will do what you want, with wait-free/lock-free guarantees and without the need for a C++11 compiler.

I am adding this answer now because the lock-free library is quite new to boost (since 1.53 I believe)

On thing to remember here is that the default param must be the last param in the function definition.

Following code will not compile:

void fun(int first, int second = 10, int third);

Following code will compile:

void fun(int first, int second, int third = 10);

From the documentation,

bool array_walk ( array &$array , callback $funcname [, mixed $userdata ] ) <-return bool

array_walk takes an array and a function F and modifies it by replacing every element x with F(x).

array array_map ( callback $callback , array $arr1 [, array $... ] )<-return array

array_map does the exact same thing except that instead of modifying in-place it will return a new array with the transformed elements.

array array_filter ( array $input [, callback $callback ] )<-return array

array_filter with function F, instead of transforming the elements, will remove any elements for which F(x) is not true

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt

.

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

After some investigation between the pro and cons, the company I was involved with also decided to go for TFS. Not because GIT isn't a good version control system, but most importantly for the fully integrated ALM solution that TFS delivers. If only the version control feature was important, the choice may probably have been GIT. The steep GIT learning curve for regular developers may however not be underestimated.

See a detailed explanation in my blog post TFS as a true cross-technology platform.

The for attribute of the <label> tag should be equal to the id attribute of the related element to bind them together.

If you really need to use a secure foreach interface to iterate an object and make it reusable and clean with a npm module, then use this, https://www.npmjs.com/package/foreach-object

Ex:

import each from 'foreach-object';
   
const object = {
   firstName: 'Arosha',
   lastName: 'Sum',
   country: 'Australia'
};
   
each(object, (value, key, object) => {
   console.log(key + ': ' + value);
});
   
// Console log output will be:
//      firstName: Arosha
//      lastName: Sum
//      country: Australia

Though @chrisb's accepted answer does answer the question, I would like to add to it the following.

A simple method I use to get the nth data or drop the nth row is the following:

df1 = df[df.index % 3 != 0]  # Excludes every 3rd row starting from 0
df2 = df[df.index % 3 == 0]  # Selects every 3rd raw starting from 0

This arithmetic based sampling has the ability to enable even more complex row-selections.

This assumes, of course, that you have an index column of ordered, consecutive, integers starting at 0.

Hugogi Raudel has came up with an interesting way to to achieve this by CSS. suppose here is our HTML markup:

<ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li> 
  <li>6</li>
  <li>7</li>
  <li>8</li>
  <li>9</li>
</ul>

You can achieve a 3-row column using this CSS code:

li:nth-child(3n+2){
  margin: 120px 0 0 -110px;
}

li:nth-child(3n+3) {
  margin: 230px 0 0 -110px;
}

And here is the end result:

What we are doing here is adding a appropriate margin for each item in the row. This approach limitation is that you have to determine the column row count. it's not going to be dynamic. I'm sure it has use cases so I included this solution here.

• Here is a live demo: http://codepen.io/HugoGiraudel/pen/DoAIB
• You can read more on this in Hugo's blog post

Answering the headline of the question (what attracted people here) and ignoring that the example used anonymous types....

This solution will also work for non-anonymous types. It should not be needed for anonymous types.

Helper class:

/// <summary>
/// Allow IEqualityComparer to be configured within a lambda expression.
/// From https://stackoverflow.com/questions/98033/wrap-a-delegate-in-an-iequalitycomparer
/// </summary>
/// <typeparam name="T"></typeparam>
public class LambdaEqualityComparer<T> : IEqualityComparer<T>
{
    readonly Func<T, T, bool> _comparer;
    readonly Func<T, int> _hash;

    /// <summary>
    /// Simplest constructor, provide a conversion to string for type T to use as a comparison key (GetHashCode() and Equals().

    /// </summary>

    public LambdaEqualityComparer(Func<T, string> toString)
        : this((t1, t2) => toString(t1) == toString(t2), t => toString(t).GetHashCode())
    {
    }

    /// <summary>
    /// Constructor.  Assumes T.GetHashCode() is accurate.
    /// </summary>
    /// <param name="comparer"></param>
    public LambdaEqualityComparer(Func<T, T, bool> comparer)
        : this(comparer, t => t.GetHashCode())
    {
    }

    /// <summary>
    /// Constructor, provide a equality comparer and a hash.
    /// </summary>
    /// <param name="comparer"></param>
    /// <param name="hash"></param>
    public LambdaEqualityComparer(Func<T, T, bool> comparer, Func<T, int> hash)
    {
        _comparer = comparer;
        _hash = hash;
    }

    public bool Equals(T x, T y)
    {
        return _comparer(x, y);
    }

    public int GetHashCode(T obj)
    {
        return _hash(obj);
    }    
}

Simplest usage:

List<Product> products = duplicatedProducts.Distinct(
    new LambdaEqualityComparer<Product>(p =>
        String.Format("{0}{1}{2}{3}",
            p.ProductId,
            p.ProductName,
            p.CategoryId,
            p.CategoryName))
        ).ToList();

The simplest (but not that efficient) usage is to map to a string representation so that custom hashing is avoided. Equal strings already have equal hash codes.

Reference:
Wrap a delegate in an IEqualityComparer

So, this is an old post, however I think I can contribute something to it.

You can always do something like this:

package com.dyna.test;  

import java.io.File;  
import java.lang.reflect.Constructor;  

public class DynamicClass{  

  @SuppressWarnings("unchecked")  
  public Object castDynamicClass(String className, String value){  
    Class<?> dynamicClass;  

    try  
    {  
      //We get the actual .class object associated with the specified name  
      dynamicClass = Class.forName(className);  



    /* We get the constructor that received only 
     a String as a parameter, since the value to be used is a String, but we could
easily change this to be "dynamic" as well, getting the Constructor signature from
the same datasource we get the values from */ 


      Constructor<?> cons =  
        (Constructor<?>) dynamicClass.getConstructor(new Class<?>[]{String.class});  

      /*We generate our object, without knowing until runtime 
 what type it will be, and we place it in an Object as 
 any Java object extends the Object class) */  
      Object object = (Object) cons.newInstance(new Object[]{value});  

      return object;  
    }  
    catch (Exception e)  
    {  
      e.printStackTrace();  
    }  
    return null;  
  }  

  public static void main(String[] args)  
  {   
    DynamicClass dynaClass = new DynamicClass();  

    /* 
 We specify the type of class that should be used to represent 
 the value "3.0", in this case a Double. Both these parameters 
 you can get from a file, or a network stream for example. */  
    System.out.println(dynaClass.castDynamicClass("java.lang.Double", "3.0"));  

    /* 
We specify a different value and type, and it will work as 
 expected, printing 3.0 in the above case and the test path in the one below, as the Double.toString() and 
 File.toString() would do. */  
    System.out.println(dynaClass.castDynamicClass("java.io.File", "C:\\testpath"));  
  }  

Of course, this is not really dynamic casting, as in other languages (Python for example), because java is a statically typed lang. However, this can solve some fringe cases where you actually need to load some data in different ways, depending on some identifier. Also, the part where you get a constructor with a String parameter could be probably made more flexible, by having that parameter passed from the same data source. I.e. from a file, you get the constructor signature you want to use, and the list of values to be used, that way you pair up, say, the first parameter is a String, with the first object, casting it as a String, next object is an Integer, etc, but somehwere along the execution of your program, you get now a File object first, then a Double, etc.

In this way, you can account for those cases, and make a somewhat "dynamic" casting on-the-fly.

Hope this helps anyone as this keeps turning up in Google searches.

Is just this:

int strcmp(char *str1, char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

if you want more fast, you can add "register " before type, like this: register char

then, like this:

int strcmp(register char *str1, register char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

this way, if possible, the register of the ALU are used.

var_dump($obj); 

If you want more info you can use a ReflectionClass:

http://www.phpro.org/manual/language.oop5.reflection.html

You cannot use primitive types in HashMap. int, or double don't work. You have to use its enclosing type. for an example

Map<String,Integer> m = new HashMap<String,Integer>();

Now both are objects, so this will work.

// simple example using the concept of setInterval

$(document).ready(function(){
var g = $('.jumping');
function blink(){
  g.animate({ 'left':'50px' 
  }).animate({
     'left':'20px'
        },1000)
}
setInterval(blink,1500);
});

Typically sites that do this by loading content via ajax and listening to the readystatechanged event to update the DOM with a loading GIF or the content.

How are you currently loading your content?

The code would be similar to this:

function load(url) {
    // display loading image here...
    document.getElementById('loadingImg').visible = true;
    // request your data...
    var req = new XMLHttpRequest();
    req.open("POST", url, true);

    req.onreadystatechange = function () {
        if (req.readyState == 4 && req.status == 200) {
            // content is loaded...hide the gif and display the content...
            if (req.responseText) {
                document.getElementById('content').innerHTML = req.responseText;
                document.getElementById('loadingImg').visible = false;
            }
        }
    };
    request.send(vars);
}

There are plenty of 3rd party javascript libraries that may make your life easier, but the above is really all you need.

To me the first answer by Rikus Khan was almost what I needed. It wasn't enough to go to ,e.g. General > Editors > Text editors and click Restore Defaults. I had to choose every single subcategory, namely: Accessibility, Annotations, Hyperlinking, etc., and manually restore their defaults as well. Apparently restoring defaults doesn't propagate down the tree.

The problem I had was the underscoring of warnings and errors in Java editor changed to highliting (after importing RainbowDrops.epf, recommended by the MoonRise UI Theme) and didn't want to revert when changing syntax coloring and other related options. This option itself is located in the aforementioned Annotations > Errors and Warnings.

The best way for accomplishing this operation in Laravel 3 seems to be the use of the Fluent interface to truncate the table as shown below

DB::query("TRUNCATE TABLE mytable");

Go to:

Settings -> Preferences You will see a dialog box. There click the Backup / Auto-completion tab where you can set the auto complete option :)

Apache

1. Run cmd as administrator
2. Go to the Apache bin directory, for example, C:\xampp\apache\bin
3. Run: httpd.exe -k install more information
4. Restart the computer, or run the service manually (from services.msc)

MySQL

1. Run cmd as administrator
2. Go to the MySQL bin directory, for example, C:\xampp\mysql\bin
3. Run: mysqld.exe --install more information
4. Restart the computer, or run the service manually (from services.msc)

Due to some problem my adb.exe, was lost. My space of work suffered an electrical energy interruption, after that, I could not run or compile android programs.

Adb.exe is a file which should be located in your [android directory]/sdk/platform-tools. In my case, the file dissapeared, however the platform-tools was ther. My solution was as follows:

• I changed the name directory of [android directory]/sdk/platform-tools towards platform-tools_OLD, in order to hide it for android studio without erase it.
• In [android directory]/sdk there is a file SDK Manager.exe, ... I launched it.
• A window of "Android SDK Manager" is shown, then, in the Tools folder I chose "Android SDK Platform Tools" and then, Install packages.
• Enter to Android Studio

This was well for me

You could try this

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),FALSE, TRUE)

-or-

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),"FALSE", "File found in row "   & MATCH(<single column I value>,<entire column E range>,0))

you could replace <single column I value> and <entire column E range> with named ranged. That'd probably be the easiest.

Just drag that formula all the way down the length of your I column in whatever column you want.

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

why do that to yourself?

jQuery:

$("#element").fadeOut();
$("#element").fadeIn();

I think that's easier.

If your app is written in TypeScript, try

(global as any).logger = // ...

or

Object.assign(global, { logger: // ... })

However, I will do it only when React Native's __DEV__ in testing environment.

i think you problem is not the selector file.

you have to add

<imagebutton ..
    android:clickable="true"
/>

to your image buttons.

by default the onClick is handled at the listitem level (parent). and the imageButtons dont recieve the onClick.

when you add the above attribute the image button will receive the event and the selector will be used.

check this POST which explains the same for checkbox.

I think my code its what everyone need:

ping -w 5000 -t -l 4000 -4 localhost|cmd /q /v /c "(pause&pause)>nul &for /l %a in () do (for /f "delims=*" %a in ('powershell get-date -format "{ddd dd-MMM-yyyy HH:mm:ss}"') do (set datax=%a) && set /p "data=" && echo([!datax!] - !data!)&ping -n 2 localhost>nul"

to display:

note: code to be used inside a command line, and you must have powershell preinstalled on os.

Well, the reason to use the pointer would be exactly the same that the reason to use pointers in C allocated with malloc: if you want your object to live longer than your variable!

It is even highly recommended to NOT use the new operator if you can avoid it. Especially if you use exceptions. In general it is much safer to let the compiler free your objects.

You just need to replace all image network paths to byte strings in HTML string. For this first you required HtmlAgilityPack to convert Html string to Html document. https://www.nuget.org/packages/HtmlAgilityPack

Find Below code to convert each image src network path(or local path) to byte sting. It will definitely display all images with network path(or local path) in IE,chrome and firefox.

string encodedHtmlString = Emailmodel.DtEmailFields.Rows[0]["Body"].ToString();

        // Decode the encoded string.
        StringWriter myWriter = new StringWriter();
        HttpUtility.HtmlDecode(encodedHtmlString, myWriter);
        string DecodedHtmlString = myWriter.ToString();

        //find and replace each img src with byte string
         HtmlDocument document = new HtmlDocument();
         document.LoadHtml(DecodedHtmlString);
         document.DocumentNode.Descendants("img")
          .Where(e =>
        {
            string src = e.GetAttributeValue("src", null) ?? "";
            return !string.IsNullOrEmpty(src);//&& src.StartsWith("data:image");
        })
        .ToList()
                    .ForEach(x =>
                    {
                        string currentSrcValue = x.GetAttributeValue("src", null);                                
                        string filePath = Path.GetDirectoryName(currentSrcValue) + "\\";
                        string filename = Path.GetFileName(currentSrcValue);
                        string contenttype = "image/" + Path.GetExtension(filename).Replace(".", "");
                        FileStream fs = new FileStream(filePath + filename, FileMode.Open, FileAccess.Read);
                        BinaryReader br = new BinaryReader(fs);
                        Byte[] bytes = br.ReadBytes((Int32)fs.Length);

I find it hard to remember the exact git config or git branch arguments as in mipadi's and Casey's answers, so I use these 2 commands to add the upstream reference:

git pull origin master
git push -u origin master

This will add the same info to your .git/config, but I find it easier to remember.

I got his error when i was trying to access UILabel. I forgot to connect the UILabel to IBOutlet in Storyboard and that was causing the app to crash with this error!!

A loose analogy is, "Meteor is to Node as Rails is to Ruby." It's a large, opinionated framework that uses Node on the server. Node itself is just a low-level framework providing functions for sending and receiving HTTP requests and performing other I/O.

Meteor is radically ambitious: By default, every page it serves is actually a Handlebars template that's kept in sync with the server. Try the Leaderboard example: You create a template that simply says "List the names and scores," and every time any client changes a name or score, the page updates with the new data—not just for that client, but for everyone viewing the page.

Another difference: While Node itself is stable and widely used in production, Meteor is in a "preview" state. There are serious bugs, and certain things that don't fit with Meteor's data-centric conceptual model (such as animations) are very hard to do.

If you love playing with new technologies, give Meteor a spin. If you want a more traditional, stable web framework built on Node, take a look at Express.

For a start, your answer variable should be of type char, not char*.

As for the if statement:

if (answer == ('Y' || 'y'))

This is first evaluating 'Y' || 'y' which, in Boolean logic (and for ASCII) is true since both of them are "true" (non-zero). In other words, you'd only get the if statement to fire if you'd somehow entered CTRLA (again, for ASCII, and where a true values equates to 1)^*a.

You could use the more correct:

if ((answer == 'Y') || (answer == 'y'))

but you really should be using:

if (toupper(answer) == 'Y')

since that's the more portable way to achieve the same end.

^*a You may be wondering why I'm putting in all sorts of conditionals for my statements. While the vast majority of C implementations use ASCII and certain known values, it's not necessarily mandated by the ISO standards. I know for a fact that at least one compiler still uses EBCDIC so I don't like making unwarranted assumptions.

For SpreadSheetGear users (a C# framework for interacting easier with spreadsheets) try this:

workbook.Worksheets[0].Cells["B1:B4"].HorizontalAlignment = HAlign.Center;. This will align all the cells in your sheet from B1 to B4 (column 2- row 1 through 4).

Use replaceFirst function of String class. There are so many variants of replace function that you can use.

Following the instructions laid out in Facebook's extending page tokens documentation I was able to get a page access token that does not expire.

I suggest using the Graph API Explorer for all of these steps except where otherwise stated.

0. Create Facebook App

If you already have an app, skip to step 1.

1. Go to My Apps.
2. Click "+ Add a New App".
3. Setup a website app.

You don't need to change its permissions or anything. You just need an app that wont go away before you're done with your access token.

1. Get User Short-Lived Access Token

1. Go to the Graph API Explorer.
2. Select the application you want to get the access token for (in the "Application" drop-down menu, not the "My Apps" menu).
3. Click "Get Token" > "Get User Access Token".
4. In the pop-up, under the "Extended Permissions" tab, check "manage_pages".
5. Click "Get Access Token".
6. Grant access from a Facebook account that has access to manage the target page. Note that if this user loses access the final, never-expiring access token will likely stop working.

The token that appears in the "Access Token" field is your short-lived access token.

2. Generate Long-Lived Access Token

Following these instructions from the Facebook docs, make a GET request to

https://graph.facebook.com/v2.10/oauth/access_token?grant_type=fb_exchange_token&client_id={app_id}&client_secret={app_secret}&fb_exchange_token={short_lived_token}

entering in your app's ID and secret and the short-lived token generated in the previous step.

You cannot use the Graph API Explorer. For some reason it gets stuck on this request. I think it's because the response isn't JSON, but a query string. Since it's a GET request, you can just go to the URL in your browser.

The response should look like this:

{"access_token":"ABC123","token_type":"bearer","expires_in":5183791}

"ABC123" will be your long-lived access token. You can put it into the Access Token Debugger to verify. Under "Expires" it should have something like "2 months".

3. Get User ID

Using the long-lived access token, make a GET request to

https://graph.facebook.com/v2.10/me?access_token={long_lived_access_token}

The id field is your account ID. You'll need it for the next step.

4. Get Permanent Page Access Token

Make a GET request to

https://graph.facebook.com/v2.10/{account_id}/accounts?access_token={long_lived_access_token}

The JSON response should have a data field under which is an array of items the user has access to. Find the item for the page you want the permanent access token from. The access_token field should have your permanent access token. Copy it and test it in the Access Token Debugger. Under "Expires" it should say "Never".

The path will only be set for the administrator account. Therefore it is important to launch command prompt as administrator, if you are not already.

Its boils down to this: math.h is from C and was created over 10 years ago. In math.h, due to its primitive nature, the abs() function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs(). When C++ was created it took math.h and made it cmath. cmath is essentially math.h but improved for C++. It improved things like having to distinguish between fabs() and abs, and just made abs() for both doubles and integer types. In summary either: Use math.h and use abs() for integers, fabs() for doubles or use cmath and just have abs for everything (easier and recommended)

Hope this helps anyone who is having the same problem!

After Windows 10 XAMPP now I installed LAMPP (XAMPP) on Ubuntu. Windows XAMPP had a lot less to configure compare to MAC (iOS) but now with Linux Ubuntu I had a few more since there are more going in Linux (a good thing).

I confused and activated mysqli.dll (and mysql.dll: erase "#" in /etc/php/7.2/cli/php.ini

I started to get the PHP Warning: PHP Startup: Unable to load dynamic library message related to dll. I commented out mysql(and i).dll in the same file but the message didn't go away up until I commented out " " in /opt/lampp/etc/php.ini.

Looks like XAMPP reads php.ini file from /etc/php/7.2/cli and makes modification in php.ini of /opt/lampp/etc. (;extension=php_pdo_mysql.dll after ";" restarted Apache and no more any message.

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

There are several different methods you have to use for different browsers. Libraries like jQuery give you a cross-browser interface that handles it all for you, though.

In line with billjamesdev answer, here is another approach to validate an URL without using a RegEx:

From Apache Commons Validator lib, look at class UrlValidator. Some example code:

Construct a UrlValidator with valid schemes of "http", and "https".

String[] schemes = {"http","https"}.
UrlValidator urlValidator = new UrlValidator(schemes);
if (urlValidator.isValid("ftp://foo.bar.com/")) {
   System.out.println("url is valid");
} else {
   System.out.println("url is invalid");
}

prints "url is invalid"

If instead the default constructor is used.

UrlValidator urlValidator = new UrlValidator();
if (urlValidator.isValid("ftp://foo.bar.com/")) {
   System.out.println("url is valid");
} else {
   System.out.println("url is invalid");
}

prints out "url is valid"

This expression will force the first letter to be alphabetic and the remaining characters to be alphanumeric or any of the following special characters: @,#,%,&,*

^[A-Za-z][A-Za-z0-9@#%&*]*$

I had the same error and the problem is that I had not correctly installed Composer.

I am using Windows and I installed Composer-Setup.exe from getcomposer.org and when you have more than one version of PHP installed you must select the version that you are running at this point of the installation

The answer above is now obsolete with Unity 5 or newer. Use this instead!

GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);

I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...

    public float playerSpeed;  //allows us to be able to change speed in Unity
public Vector2 jumpHeight;

// Use this for initialization
void Start () {

}
// Update is called once per frame
void Update ()
{
    transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f);  //makes player run

    if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space))  //makes player jump
    {
        GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);

This makes it to where you can edit the jump height in Unity itself without having to go back to the script.

Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)

The field identifiers are indeed C initializer syntax. In C++ just give the values in the correct order without the field names. Unfortunately this means you need to give them all (actually you can omit trailing zero-valued fields and the result will be the same):

address temp_address = { 0, 0, "Hamilton", "Ontario", 0 }; 

In addition to max, you can also sort:

>>> lis
[(101, 153), (255, 827), (361, 961)]
>>> sorted(lis,key=lambda x: x[1], reverse=True)[0]
(361, 961)

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

I was getting this error when I try to capture image or take image from gallery what works for me is to remove both

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

and

android:screenOrientation="portrait"
