Frames were not deprecated in HTML5, but were deprecated in XHTML 1.1 Strict and 2.0, but remained in XHTML Transitional and returned in HTML5. Also here is an interesting article on using CSS to mimic frames without frames. I just tested it in IE 8, FF 3, Opera 11, Safari 5, Chrome 8. I love frames, but they do have their problems, particularly with search engines, bookmarks and printing and with CSS you can create print or display only content. I'm hoping to upgrade Alex's XHTML/CSS frame without frames solution to HTML5/CSS3.

It is possible to debug by writing key word "debugger" to place where you want to debug and just press F5 key to debug JavaScript code.

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

python -c "from os import system; system('clear')"

I usually try to use it like this:

• DEBUG: Information interesting for Developers, when trying to debug a problem.
• INFO: Information interesting for Support staff trying to figure out the context of a given error
• WARN to FATAL: Problems and Errors depending on level of damage.

Usually for normal transition we use,

let next:SecondViewController = SecondViewController()
self.presentViewController(next, animated: true, completion: nil)

But sometimes when using navigation controller, you might face a black screen. In that case, you need to use like,

let next:ThirdViewController = storyboard?.instantiateViewControllerWithIdentifier("ThirdViewController") as! ThirdViewController
self.navigationController?.pushViewController(next, animated: true)

Moreover none of the above solution preserves navigationbar when you call from storyboard or single xib to another xib. If you use nav bar and want to preserve it just like normal push, you have to use,

Let's say, "MyViewController" is identifier for MyViewController

let viewController = MyViewController(nibName: "MyViewController", bundle: nil)
self.navigationController?.pushViewController(viewController, animated: true)

In bash script, what does #!/bin/bash at the 1st line mean ?

In Linux system, we have shell which interprets our UNIX commands. Now there are a number of shell in Unix system. Among them, there is a shell called bash which is very very common Linux and it has a long history. This is a by default shell in Linux.

When you write a script (collection of unix commands and so on) you have a option to specify which shell it can be used. Generally you can specify which shell it wold be by using Shebang(Yes that's what it's name).

So if you #!/bin/bash in the top of your scripts then you are telling your system to use bash as a default shell.

Now coming to your second question :Is there a difference between #!/bin/bash and #!/bin/sh ?

The answer is Yes. When you tell #!/bin/bash then you are telling your environment/ os to use bash as a command interpreter. This is hard coded thing.

Every system has its own shell which the system will use to execute its own system scripts. This system shell can be vary from OS to OS(most of the time it will be bash. Ubuntu recently using dash as default system shell). When you specify #!/bin/sh then system will use it's internal system shell to interpreting your shell scripts.

Visit this link for further information where I have explained this topic.

Hope this will eliminate your confusions...good luck.

For updating a record:

 UPDATE Employees SET [Photo] = (SELECT
 MyImage.* from Openrowset(Bulk
 'C:\photo.bmp', Single_Blob) MyImage)
 where Id = 10

Notes:

• Make sure to add the 'BULKADMIN' Role Permissions for the login you are using.
• Paths are not pointing to your computer when using SQL Server Management Studio. If you start SSMS on your local machine and connect to a SQL Server instance on server X, the file C:\photo.bmp will point to hard drive C: on server X, not your machine!

1. Find the process ID (PID) for the port (e.g.: 8080)

   On Windows:

   netstat -ao | find "8080"
   

   Other Platforms other than windows :

   lsof -i:8080
   

2. Kill the process ID you found (e.g.: 20712)

   On Windows:

   Taskkill /PID  20712 /F
   

   Other Platforms other than windows :

   kill -9 20712   or kill 20712
   

OpenSSL has a horrible documentation with no code examples, but here you are:

#include <openssl/sha.h>

bool simpleSHA256(void* input, unsigned long length, unsigned char* md)
{
    SHA256_CTX context;
    if(!SHA256_Init(&context))
        return false;

    if(!SHA256_Update(&context, (unsigned char*)input, length))
        return false;

    if(!SHA256_Final(md, &context))
        return false;

    return true;
}

Usage:

unsigned char md[SHA256_DIGEST_LENGTH]; // 32 bytes
if(!simpleSHA256(<data buffer>, <data length>, md))
{
    // handle error
}

Afterwards, md will contain the binary SHA-256 message digest. Similar code can be used for the other SHA family members, just replace "256" in the code.

If you have larger data, you of course should feed data chunks as they arrive (multiple SHA256_Update calls).

Edit: The answer below may be satisfactory, but it has some drawbacks:

1. There is a noticeable pause for the running of the script. I'm on a 160 ms latency, and it's enough to be annoying.

2. It works by building a new range each time you edit a given row. This gives an 'invalid contents' to previous entries some of the time

I hope others can clean this up somewhat.

Here's another way to do it, that saves you a ton of range naming:

Three sheets in the worksheet: call them Main, List, and DRange (for dynamic range.) On the Main sheet, column 1 contains a timestamp. This time stamp is modified onEdit.

On List your categories and subcategories are arranged as a simple list. I'm using this for plant inventory at my tree farm, so my list looks like this:

Group   | Genus | Bot_Name
Conifer | Abies | Abies balsamea
Conifer | Abies | Abies concolor
Conifer | Abies | Abies lasiocarpa var bifolia
Conifer | Pinus | Pinus ponderosa
Conifer | Pinus | Pinus sylvestris
Conifer | Pinus | Pinus banksiana
Conifer | Pinus | Pinus cembra
Conifer | Picea | Picea pungens
Conifer | Picea | Picea glauca
Deciduous | Acer | Acer ginnala
Deciduous | Acer | Acer negundo
Deciduous | Salix | Salix discolor
Deciduous | Salix | Salix fragilis
...

Where | indicates separation into columns.
For convenience I also used the headers as names for named ranges.

DRrange A1 has the formula

=Max(Main!A2:A1000)

This returns the most recent timestamp.

A2 to A4 have variations on:

=vlookup($A$1,Inventory!$A$1:$E$1000,2,False) 

with the 2 being incremented for each cell to the right.

On running A2 to A4 will have the currently selected Group, Genus and Species.

Below each of these, is a filter command something like this:

=unique(filter(Bot_Name,REGEXMATCH(Bot_Name,C1)))

These filters will populate a block below with matching entries to the contents of the top cell.

The filters can be modified to suit your needs, and to the format of your list.

Back to Main: Data validation in Main is done using ranges from DRange.

The script I use:

function onEdit(event) {

  //SETTINGS
  var dynamicSheet='DRange'; //sheet where the dynamic range lives
  var tsheet = 'Main'; //the sheet you are monitoring for edits
  var lcol = 2; //left-most column number you are monitoring; A=1, B=2 etc
  var rcol = 5; //right-most column number you are monitoring
  var tcol = 1; //column number in which you wish to populate the timestamp
  //

  var s = event.source.getActiveSheet();
  var sname = s.getName();
  if (sname == tsheet) {
    var r = event.source.getActiveRange();
    var scol = r.getColumn();  //scol is the column number of the edited cell
    if (scol >= lcol && scol <= rcol) {
      s.getRange(r.getRow(), tcol).setValue(new Date());
      for(var looper=scol+1; looper<=rcol; looper++) {
         s.getRange(r.getRow(),looper).setValue(""); //After edit clear the entries to the right
      }
    }
  }
}

I meet this error too when I run a wordpress on my Fedora system.

I googled it, and find a way to fix this.

Maybe this will help you too.

1. check mysql config : my.cnf

    cat /etc/my.cnf | grep tmpdir
   

   I can't see anything in my my.cnf

2. add tmpdir=/tmp to my.cnf under [mysqld]

3. restart web/app and mysql server

   /etc/init.d/mysqld restart

I got the same error message. In my case, it was due to not using quotes.

Although the column was supposed to have only numbers, it was a Varchar column, and one of the rows had a letter in it.

So I was doing this:

select * from mytable where myid = 1234

While I should be doing this:

select * from mytable where myid = '1234'

If the column had all numbers, the conversion would have worked, but not in this case.

Start an export process to create an apk for your app and use your production key. The very last page displays both your SHA1 and MD5 certificate fingerprints

I know it's an old question. But it keeps showing in google first position and all it says it's "install node.js". For a newbie this is not obvious, so all you have to do is go to the node.js website and search for the command for your linux distribution version or any other operating system. Here is the link: https://nodejs.org/en/download/package-manager/

In this page you have to choose your operating system and you'll find your command. Then you just log into your console as a root (using putty for instance) and execute that command.

After that, you log as normal user and go again inside your laravel application folder and run again npm install command, and it should work. Hope it helps.

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

UPDATE(OCT 2017)

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

    <div class="p-1">
      <p>Hello there</p>
    </div>
    <div class="p-1">
      <a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>
      <a href="#" class="btn btn-warning" onclick="changeBack()">Rs</a>

Check out www.connectionstrings.com for a ton of samples of proper connection strings.

In your case, use this:

Server=localhost;Database=employeedetails;Integrated Security=SSPI

Update: obviously, the service account used to run ASP.NET web apps doesn't have access to SQL Server, and judging from that error message, you're probably using "anonymous authentication" on your web site.

So you either need to add this account IIS APPPOOL\ASP.NET V4.0 as a SQL Server login and give that login access to your database, or you need to switch to using "Windows authentication" on your ASP.NET web site so that the calling Windows account will be passed through to SQL Server and used as a login on SQL Server.

Yes, but if you have your structure in a union then you cannot. It is the same as a class.

struct Example
{
   unsigned int mTest;
   Example()
   {
   }
};

Unions will not allow constructors in the structs. You can make a constructor on the union though. This question relates to non-trivial constructors in unions.

I know this is going to be a late answer, however here is the most correct answer.

In MySQL database, change your timestamp default value into CURRENT_TIMESTAMP. If you have old records with the fake value, you will have to manually fix them.

What do you mean by delete? In Python, removing a reference (or a name) can be done with the del keyword, but if there are other names to the same object that object will not be deleted.

--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

compared to:

--> test = 5
--> other is test  # check that both name refer to the exact same object
True
--> del test       # gets rid of test, but the object is still referenced by other
--> print(other)
5

I have written a java example for this case:

Use json.org library to retrieve JSONObjects and JSONArrays. The example below uses blockchain.info's data which can be obtained as JSONObject.

    public class main 
    {
        public static void main(String[] args) throws MalformedURLException, IOException
        {
            JSONObject data = getJSONfromURL("https://blockchain.info/charts/market-price?format=json");
            JSONArray data_array = data.getJSONArray("values");

            for (int i = 0; i < data_array.length(); i++)
            {
                JSONObject price_point = data_array.getJSONObject(i);

                //  Unix time
                int x = price_point.getInt("x");

                //  Bitcoin price at that time
                double y = price_point.getDouble("y");

                //  Do something with x and y.
            }

        }

        public static JSONObject getJSONfromURL(String URL)
        {
            try
            {
                URLConnection uc;
                URL url = new URL(URL);
                uc = url.openConnection();
                uc.setConnectTimeout(10000);
                uc.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
                uc.connect();

                BufferedReader rd = new BufferedReader(
                        new InputStreamReader(uc.getInputStream(), 
                        Charset.forName("UTF-8")));

                StringBuilder sb = new StringBuilder();
                int cp;
                while ((cp = rd.read()) != -1)
                {
                    sb.append((char)cp);
                }

                String jsonText = (sb.toString());            

                return new JSONObject(jsonText.toString());
            } catch (IOException ex)
            {
                return null;
            }
        }
    }

Microsoft has listened to the cry for supporting installers (MSI) in Visual Studio and released the Visual Studio Installer Projects Extension. You can now create installers in Visual Studio 2013; download the extension here from the visualstudiogallery.

Use MarkDownLog library (you can find it on NuGet)

you can simply use the extension ToMarkdownTable() to any collection, it does all the formatting for you.

 Console.WriteLine(
    yourCollection.Select(s => new
                    {
                        column1 = s.col1,
                        column2 = s.col2,
                        column3 = s.col3,
                        StaticColumn = "X"
                    })
                    .ToMarkdownTable());

Output looks something like this:

Column1  | Column2   | Column3   | StaticColumn   
--------:| ---------:| ---------:| --------------
         |           |           | X              

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

I asked recently about something similar.

If you use flags you can add an extension method to enums to make checking the contained flags easier (see post for detail)

This allows you to do:

[Flags]
public enum PossibleOptions : byte
{
    None = 0,
    OptionOne = 1,
    OptionTwo = 2,
    OptionThree = 4,
    OptionFour = 8,

    //combinations can be in the enum too
    OptionOneAndTwo = OptionOne | OptionTwo,
    OptionOneTwoAndThree = OptionOne | OptionTwo | OptionThree,
    ...
}

Then you can do:

PossibleOptions opt = PossibleOptions.OptionOneTwoAndThree 

if( opt.IsSet( PossibleOptions.OptionOne ) ) {
    //optionOne is one of those set
}

I find this easier to read than the most ways of checking the included flags.

DO NOT EDIT studio.vmoptions ,It may not work.

In gradle.properties file (in app directory) add this :

org.gradle.parallel=true
org.gradle.jvmargs=-Xmx7g -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Hope this gist help https://gist.github.com/imammubin/a587192982ff8db221da14d094df6fb4

MainActivity as Screen Launcher with handler & runnable function, the Runnable run to login page or feed page with base preference login user with firebase.

If you check the info on python.org, you can see this summary:

Version Time (seconds)
Basic loop 3.47
Eliminate dots 2.45
Local variable & no dots 1.79
Using map function 0.54

But you really should read the above article in details to understand the cause of the performance difference.

I also strongly suggest you should time your code by using timeit. At the end of the day, there can be a situation where, for example, you may need to break out of for loop when a condition is met. It could potentially be faster than finding out the result by calling map.

Uncomment the following line : [System.Web.Script.Services.ScriptService]

Service will start working fine.

[WebService(Namespace = "http://tempuri.org/")]

 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

[System.Web.Script.Services.ScriptService]

public class WebService : System.Web.Services.WebService 
{

If you want to do this purely in CSS then you'd have a class that you'd assign to each alternate list item. E.g.

<ul>
    <li class="alternate"><a href="link">Link 1</a></li>
    <li><a href="link">Link 2</a></li>
    <li class="alternate"><a href="link">Link 3</a></li>
    <li><a href="link">Link 4</a></li>
    <li class="alternate"><a href="link">Link 5</a></li>
</ul>

If your list is dynamically generated, this task would be much easier.

If you don't want to have to manually update this content each time, you could use the jQuery library and apply a style alternately to each <li> item in your list:

<ul id="myList">
    <li><a href="link">Link 1</a></li>
    <li><a href="link">Link 2</a></li>
    <li><a href="link">Link 3</a></li>
    <li><a href="link">Link 4</a></li>
    <li><a href="link">Link 5</a></li>
</ul>

And your jQuery code:

$(document).ready(function(){
  $('#myList li:nth-child(odd)').addClass('alternate');
});

I had a similar issue when I checked out a web project from a github repo on my eclipse. src/main/java was directly inside the project root in Package Explorer. My expectation was that src/main/java be visible inside a source folder "Java Resources". There were few things which I did to achieve this.

1. Right click on Project > Build Path > Configure Build Path..
2. Select filter "Java Build Path" and click on Tab "Libraries" Verify your "JRE System Library". If it is not pointing to your latest JDK, then you can click on Edit Button and follow the subsequent dialog boxes to select most appropriate JDK home path in your system.

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

If you are using the hex codes, you can add two more digits at the end of the code to represent the alpha channel:

E.g. half-transparency red:

plot(1:100, main="Example of Plot With Transparency")
lines(1:100 + sin(1:100*2*pi/(20)), col='#FF000088', lwd=4)
mtext("use `col='#FF000088'` for the lines() function")

I'll be using this Live Event from NASA TV as an example:

I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).

Add the permission:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Add receiver and service:

<receiver android:enabled="true" android:name=".BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
<service android:name="Launcher" />

Create class Launcher:

public class Launcher extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        new AsyncTask<Service, Void, Service>() {

            @Override
            protected Service doInBackground(Service... params) {
                Service service = params[0];
                PackageManager pm = service.getPackageManager();
                try {
                    Intent target = pm.getLaunchIntentForPackage("your.package.id");
                    if (target != null) {
                        service.startActivity(target);
                        synchronized (this) {
                            wait(3000);
                        }
                    } else {
                        throw new ActivityNotFoundException();
                    }
                } catch (ActivityNotFoundException | InterruptedException ignored) {
                }
                return service;
            }

            @Override
            protected void onPostExecute(Service service) {
                service.stopSelf();
            }

        }.execute(this);

        return START_STICKY;
    }
}

Create class BootUpReceiver to do action after android reboot.

For example launch MainActivity:

public class BootUpReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent target = new Intent(context, MainActivity.class);  
        target.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(target);  
    }
}

I ran into same issue when running:

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"_

I solved it as

$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home    

$ ls /Library/Java/JavaVirtualMachines/

jdk-11.0.1.jdk      
jdk1.8.0_202.jdk

Change Java to use 1.8

$ export JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home'

Then the same command runs fine

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"

Auto Refresh Workbook for example every 5 sec. Apply to module

Public Sub Refresh()
'refresh
ActiveWorkbook.RefreshAll

alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
    Application.OnTime alertTime, "Refresh"

End Sub

Apply to Workbook on Open

Private Sub Workbook_Open()
alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
Application.OnTime alertTime, "Refresh"
End Sub

:)

The query string that I used to to escape the new line character in JS : LOAD DATA LOCAL INFILE 'Data.csv' INTO TABLE DEMO FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 ROWS;

This involves new ES6 syntax - Template Literals `` and I tried changing '\n' to '\r\n' and worked perfectly in my case.

PS: This example is my query to upload CSV data into mysql DB.

It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.

If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate and colMeans, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.

However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for loop.

> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > 

So in your case, if you just wanted to print the mean of your Tandem object 5 times:

for (ii in 1:5) {     Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL)     TandemMean <- mean(Tandem)     print(TandemMean) } 

As mentioned above, replicate is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.

set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) {     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) }  tandem[1] tandem[100] tandem[20:25] 

...creates this output:

> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { +     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } >  > tandem[1] [[1]] [1] 1.511923  > tandem[100] [[1]] [1] 1.496777  > tandem[20:25] [[1]] [1] 1.500669  [[2]] [1] 1.487552  [[3]] [1] 1.503409  [[4]] [1] 1.501362  [[5]] [1] 1.499728  [[6]] [1] 1.492798  >  

Microsoft recently modified the reflection API rendering most of these answers obsolete. The following should work on modern platforms (including Xamarin.Forms and UWP):

obj.GetType().GetTypeInfo().GetDeclaredMethod("MethodName").Invoke(obj, yourArgsHere);

Or as an extension method:

public static object InvokeMethod<T>(this T obj, string methodName, params object[] args)
{
    var type = typeof(T);
    var method = type.GetTypeInfo().GetDeclaredMethod(methodName);
    return method.Invoke(obj, args);
}

Note:

• If the desired method is in a superclass of obj the T generic must be explicitly set to the type of the superclass.

• If the method is asynchronous you can use await (Task) obj.InvokeMethod(…).

That InvocationTargetException is probably wrapping up your ArrayIndexOutOfBoundsException. There is no telling upfront when using reflection what that method can throw -- so rather than using a throws Exception approach, all the exceptions are being caught and wrapped up in InvocationTargetException.

Generally what's meant by that is a fairly intimate familiarity with one (or probably more) of the .NET languages (C#, VB.NET, etc.) and one (or less probably more) of the .NET stacks (WinForms, ASP.NET, WPF, etc.).

As for a specific "formal definition", I don't think you'll find one beyond that. The job description should be specific about what they're looking for. I wouldn't consider a job listing that asks for a ".NET developer" and provides no more detail than that to be sufficiently descriptive.

Some of the scenarios, object.item would not be loaded or will be undefined.

Use ng-init

<select ng-init="object.item=2" ng-model="object.item"
ng-options="item.id as item.name for item in list"

If you need one item to be left aligned (like a header) but then multiple items right aligned (like 3 images), then you would do something like this:

h1 {
   flex-basis: 100%; // forces this element to take up any remaining space
}

img {
   margin: 0 5px; // small margin between images
   height: 50px; // image width will be in relation to height, in case images are large - optional if images are already the proper size
}

Here's what that will look like (only relavent CSS was included in snippet above)

you can't change the DateTime object, it's immutable. However, you can set it to a new value, for example:

var newDate = oldDate.Date + new TimeSpan(11, 30, 55);

If you use jQuery you can write:

$( _checkbox ).click( function( e ){ /*process event here*/ } )

Luckily git stash pop does not change the stash in the case of a conflict!

So nothing, to worry about, just clean up your code and try it again.

Say your codebase was clean before, you could go back to that state with: git checkout -f
Then do the stuff you forgot, e.g. git merge missing-branch
After that just fire git stash pop again and you get the same stash, that conflicted before.

Keep in mind: The stash is safe, however, uncommitted changes in the working directory are of course not. They can get messed up.

I know this message is old and was a long time ago - but i also had problem with with the exact same error:

the problem I had was relates to the fact the encrypted text was converted to String and to byte[] when trying to DECRYPT it.

    private Key getAesKey() throws Exception {
    return new SecretKeySpec(Arrays.copyOf(key.getBytes("UTF-8"), 16), "AES");
}

private Cipher getMutual() throws Exception {
    Cipher cipher = Cipher.getInstance("AES");
    return cipher;// cipher.doFinal(pass.getBytes());
}

public byte[] getEncryptedPass(String pass) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.ENCRYPT_MODE, getAesKey());
    byte[] encrypted = cipher.doFinal(pass.getBytes("UTF-8"));
    return encrypted;

}

public String getDecryptedPass(byte[] encrypted) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.DECRYPT_MODE, getAesKey());
    String realPass = new String(cipher.doFinal(encrypted));
    return realPass;
}

If you want to change it app wide, you can add the logic to your App Delegate

class AppDelegate: UIResponder, UIApplicationDelegate {

    //... truncated

   func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {

        // set up your background color view
        let colorView = UIView()
        colorView.backgroundColor = UIColor.yellowColor()

        // use UITableViewCell.appearance() to configure 
        // the default appearance of all UITableViewCells in your app
        UITableViewCell.appearance().selectedBackgroundView = colorView

        return true
    }

    //... truncated
}

Since it's an environment variable (alias has a different definition in bash), you need to evaluate it with something like:

cd "${myFold}"

or:

cp "${myFold}/someFile" /somewhere/else

But I actually find it easier, if you just want the ease of switching into that directory, to create a real alias (in one of the bash startup files like .bashrc), so I can save keystrokes:

alias myfold='cd ~/Files/Scripts/Main'

Then you can just use (without the cd):

myfold

To get rid of the definition, you use unalias. The following transcript shows all of these in action:

pax> cd ; pwd ; ls -ald footy
/home/pax
drwxr-xr-x 2 pax pax 4096 Jul 28 11:00 footy

pax> footydir=/home/pax/footy ; cd "$footydir" ; pwd
/home/pax/footy

pax> cd ; pwd
/home/pax

pax> alias footy='cd /home/pax/footy' ; footy ; pwd
/home/pax/footy

pax> unalias footy ; footy
bash: footy: command not found

To generate a number between 10 to 20 inclusive, you can use java.util.Random

int myNumber = new Random().nextInt(11) + 10

This is not your answer and this is an alternate way to process the form submission

$('.signinform').click(function(e) { 
      e.preventDefault();
      $.ajax({
      type: "POST",
      url: 'index.php/user/signin', // target element(s) to be updated with server response 
      dataType:'json',
      success : function(response){ console.log(response); alert(response)}
     });
}); 

You have #include "fun.cpp" in mainfile.cpp so compiling with:

g++ -o hw1 mainfile.cpp

will work, however if you compile by linking these together like

g++ -g -std=c++11 -Wall -pedantic   -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic   -c -o mainfile.o mainfile.cpp

As they mention above, adding #include "fun.hpp" will need to be done or it won't work. However, your case with the funct() function is slightly different than my problem.

I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.

Get your response via a regular http-request, using:

• Apache HttpComponents
• the built-in URLConnection con = new URL("http://example.com").openConnection();

The next step is parsing it. Take a look at this article for a choice of parser.

**Don't do this (why?):

Quoting the C99 standard doc that i found online: "Setting the file position indicator to end-of-file, as with fseek(file, 0, SEEK_END), has undefined behavior for a binary stream (because of possible trailing null characters) or for any stream with state-dependent encoding that does not assuredly end in the initial shift state.**

Change the definition to int so that error messages can be transmitted, and then use fseek() and ftell() to determine the file size.

int fsize(char* file) {
  int size;
  FILE* fh;

  fh = fopen(file, "rb"); //binary mode
  if(fh != NULL){
    if( fseek(fh, 0, SEEK_END) ){
      fclose(fh);
      return -1;
    }

    size = ftell(fh);
    fclose(fh);
    return size;
  }

  return -1; //error
}

Assuming your script is something like the below snippet and named testargs.ps1

param ([string]$w)
Write-Output $w

You can call this at the commandline as:

PowerShell.Exe -File C:\scripts\testargs.ps1 "Test String"

This will print "Test String" (w/o quotes) at the console. "Test String" becomes the value of $w in the script.

Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.

The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.

Here is a good article about fluid vs. flex.

The problem is at [System.Web.Services.WebMethod], add [WebMethod(EnableSession = false)] and you could get rid of page life cycle, by default EnableSession is true in Page and making page to come in life though life cycle events..

Please refer below page for more details http://msdn.microsoft.com/en-us/library/system.web.configuration.pagessection.enablesessionstate.aspx

I did it with an ajax post and then returned using a data url:

$(document).ready(function () {
    var exportClick = function () {
        $.ajax({
           url: "/api/test.php",
           type: "POST",
           dataType: "text",
           data: {
              action: "getCSV",
              filter: "name = 'smith'",
           },
           success: function(data) {
              var w = window.open('data:text/csv;charset=utf-8,' + encodeURIComponent(data));
              w.focus();
           },
           error: function () {
              alert('Problem getting data');
           },
        });
    }
});

I had the same issue and used a combination of the above solutions (and added a twist of my own). Note that I had to specify column widths to keep them consistent between header and body.

In my solution, the header and footer stay fixed while the body scrolls.

<div class="table-responsive">
    <table class="table table-striped table-hover table-condensed">
        <thead>
            <tr>
                <th width="25%">First Name</th>
                <th width="13%">Last Name</th>
                <th width="25%" class="text-center">Address</th>
                <th width="25%" class="text-center">City</th>
                <th width="4%" class="text-center">State</th>
                <th width="8%" class="text-center">Zip</th>
            </tr>
        </thead>
    </table>
    <div class="bodycontainer scrollable">
        <table class="table table-hover table-striped table-condensed table-scrollable">
            <tbody>
                <!-- add rows here, specifying same widths as in header, at least on one row -->
            </tbody>
        </table>
    </div>
    <table class="table table-hover table-striped table-condensed">
        <tfoot>
            <!-- add your footer here... -->
        </tfoot>
    </table>
</div>

And then just applied the following CSS:

.bodycontainer { max-height: 450px; width: 100%; margin: 0; overflow-y: auto; }
.table-scrollable { margin: 0; padding: 0; }

I hope this helps someone else.

Generally if you are not sure of what value you will end up returning, you should consider using return-type as super-class of all the return values. In this case, where you need to return String or int, consider returning Object class(which is the base class of all the classes defined in java).

But be careful to have instanceof checks where you are calling this method. Or else you may end up getting ClassCastException.

public static void main(String args[]) {
        Object obj = myMethod(); // i am calling static method from main() which return Object
    if(obj instanceof String){
    // Do something
    }else(obj instance of Integer) {
    //do something else
     }

Following @rsplak answer: actually, using split/join way is faster than using regexp. See the performance test case

So

var result = text.split(' ').join('')

operates faster than

var result = text.replace(/\s+/g, '')

On small texts this is not relevant, but for cases when time is important, e.g. in text analisers, especially when interacting with users, that is important.

On the other hand, \s+ handles wider variety of space characters. Among with \n and \t, it also matches \u00a0 character, and that is what   is turned in, when getting text using textDomNode.nodeValue.

So I think that conclusion in here can be made as follows: if you only need to replace spaces ' ', use split/join. If there can be different symbols of symbol class - use replace(/\s+/g, '')

lubos hasko's method fails for nullables. The method below will work for nullables. I didn't come up with it, though. I found it via Google: http://web.archive.org/web/20101214042641/http://dogaoztuzun.com/post/C-Generic-Type-Conversion.aspx Credit to "Tuna Toksoz"

Usage first:

TConverter.ChangeType<T>(StringValue);  

The class is below.

public static class TConverter
{
    public static T ChangeType<T>(object value)
    {
        return (T)ChangeType(typeof(T), value);
    }

    public static object ChangeType(Type t, object value)
    {
        TypeConverter tc = TypeDescriptor.GetConverter(t);
        return tc.ConvertFrom(value);
    }

    public static void RegisterTypeConverter<T, TC>() where TC : TypeConverter
    {

        TypeDescriptor.AddAttributes(typeof(T), new TypeConverterAttribute(typeof(TC)));
    }
}

OAuth v2 specs indicates:

Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.

My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .

public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
    Iterator<String> keys = json.keys();
    while(keys.hasNext()){
        String key = keys.next();
        String val = null;
        try{
             JSONObject value = json.getJSONObject(key);
             parse(value,out);
        }catch(Exception e){
            val = json.getString(key);
        }

        if(val != null){
            out.put(key,val);
        }
    }
    return out;
}

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

    String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";

    JSONObject object = new JSONObject(json);

    JSONObject info = object.getJSONObject("ipinfo");

    Map<String,String> out = new HashMap<String, String>();

    parse(info,out);

    String latitude = out.get("latitude");
    String longitude = out.get("longitude");
    String city = out.get("city");
    String state = out.get("state");
    String country = out.get("country");
    String postal = out.get("postal_code");

    System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);

    System.out.println("ALL VALUE " + out);

}

Output:

    Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}

Here is a wget script in Python:

# From python cookbook, 2nd edition, page 487
import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print

A StreamReader is for text, not plain bytes. Don't use a StreamReader, and instead read directly from the underlying stream.

Unfortunately there is only the function setColumnWidth(int columnIndex, int width) from class Sheet; in which width is a number of characters in the standard font (first font in the workbook) if your fonts are changing you cannot use it. There is explained how to calculate the width in function of a font size. The formula is:

width = Truncate([{NumOfVisibleChar} * {MaxDigitWidth} + {5PixelPadding}] / {MaxDigitWidth}*256) / 256

You can always use autoSizeColumn(int column, boolean useMergedCells) after inputting the data in your Sheet.

This might work for you:

This is how dynamic languages work. It is not always a good thing though, especially if the documentation is poor - anyone tried to use a poorly documented python framework? Sometimes you have to revert to reading the source.

Here are some strategies to avoid problems with duck typing:

• create a language for your problem domain
• this will help you to name stuff properly
• use types to represent concepts in your domain language
• name function parameters using the domain language vocabulary

Also, one of the most important points:

• keep data as local as possible!

There should only be a few well-defined and documented types being passed around. Anything else should be obvious by looking at the code: Don't have weird parameter types coming from far away that you can't figure out by looking in the vicinity of the code...

Related, (and also related to docstrings), there is a technique in python called doctests. Use that to document how your methods are expected to be used - and have nice unit test coverage at the same time!

I've seen a lot of inadequate answers while trying to figure this one out. General response has been "you are trying to stop something that hasn't started" or "some other program is running on the port you need".

The problem for me turned out to be my firewall. I hadn't even considered this, but port 8005 (the port used for shutdown, thanks mindas), was blocked. I changed it, and now, no more error. Good luck.

In my Notepad++ 7.2.2, the Preferences section it's a bit different.

The option is located at: Settings / Preferences / Language / Replace by space as in the Screenshot.

I will give you a better idea

for(decltype(things.size()) i = 0; i < things.size(); i++){
                   //...
}

decltype is

Inspects the declared type of an entity or the type and value category of an expression.

So, It deduces type of things.size() and i will be a type as same as things.size(). So, i < things.size() will be executed without any warning

Finally below works for me

$("#priceSlider").slider('option',{min: 5, max: 20,value:[6,19]}); $("#priceSlider").slider("refresh");

Syntax problem on your arrays

$array1 = array(
    'a' => 'value1',
    'b' => 'value2',
    'c' => 'value3',
 );

$array2 = array(
    'a' => 'value1',
    'b' => 'value2',
    'c' => 'value3',
 );

$diff = array_diff($array1, $array2);

var_dump($diff); 

I have put the images in a convenient zip file: http://zlab.co.za/lib_help/jquery-ui.css.images.zip

As the readme.txt file in the zip file reads: Place the "images" folder in the same folder where your "jquery-ui.css" file is located.

I hope this helps :)

I think if you use a UNION it will work:

select 'header 1', 'header 2', ...
union
select col1, col2, ... from ...

I don't know of a way to specify the headers with the INTO OUTFILE syntax directly.

Note that Python3 does not read the html code as a string but as a bytearray, so you need to convert it to one with decode.

import urllib.request

fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()

mystr = mybytes.decode("utf8")
fp.close()

print(mystr)

Just for those who want to get $setPristine without having to upgrade to v1.1.x, here is the function I used to simulate the $setPristine function. I was reluctant to use the v1.1.5 because one of the AngularUI components I used is no compatible.

var setPristine = function(form) {
    if (form.$setPristine) {//only supported from v1.1.x
        form.$setPristine();
    } else {
        /*
         *Underscore looping form properties, you can use for loop too like:
         *for(var i in form){ 
         *  var input = form[i]; ...
         */
        _.each(form, function (input) {
            if (input.$dirty) {
                input.$dirty = false;
            }
        });
    }
};

Note that it ONLY makes $dirty fields clean and help changing the 'show error' condition like $scope.myForm.myField.$dirty && $scope.myForm.myField.$invalid.

Other parts of the form object (like the css classes) still need to consider, but this solve my problem: hide error messages.

What about:

 a.sort {|x,y| y[:bar]<=>x[:bar]}

It works!!

irb
>> a = [
?>   { :foo => 'foo', :bar => 2 },
?>   { :foo => 'foo', :bar => 3 },
?>   { :foo => 'foo', :bar => 5 },
?> ]
=> [{:bar=>2, :foo=>"foo"}, {:bar=>3, :foo=>"foo"}, {:bar=>5, :foo=>"foo"}]

>>  a.sort {|x,y| y[:bar]<=>x[:bar]}
=> [{:bar=>5, :foo=>"foo"}, {:bar=>3, :foo=>"foo"}, {:bar=>2, :foo=>"foo"}]

If you want to add a flag to every link, e.g. -fsanitize=address then I would not recommend using CMAKE_*_LINKER_FLAGS. Even with them all set it still doesn't use the flag when linking a framework on OSX, and maybe in other situations. Instead use link_libraries():

add_compile_options("-fsanitize=address")
link_libraries("-fsanitize=address")

This works for everything.

Just do Ctrl + Enter inside the text box

It is not good practice to hard code strings into your layout files/ code. You should add them to a string resource file and then reference them from your layout.

1. This allows you to update every occurrence of the same word in all
   layouts at the same time by just editing your strings.xml file.
2. It is also extremely useful for supporting multiple languages as a separate strings.xml file can be used for each supported language
3. the actual point of having the @string system please read over the localization documentation. It allows you to easily locate text in your app and later have it translated.
4. Strings can be internationalized easily, allowing your application to support multiple languages with a single application package file (APK).

Benefits

• Lets say you used same string in 10 different locations in the code. What if you decide to alter it? Instead of searching for where all it has been used in the project you just change it once and changes are reflected everywhere in the project.
• Strings don’t clutter up your application code, leaving it clear and easy to maintain.

Swift:

let fetchRequest = NSFetchRequest()
fetchRequest.entity = NSEntityDescription.entityForName(entityName, inManagedObjectContext: context)
fetchRequest.includesPropertyValues = false

var error:NSError?
if let results = context.executeFetchRequest(fetchRequest, error: &error) as? [NSManagedObject] {
    for result in results {
        context.deleteObject(result)
    }

    var error:NSError?
    if context.save(&error) {
        // do something after save

    } else if let error = error {
        println(error.userInfo)
    }

} else if let error = error {
    println("error: \(error)")
}

Another way to do this would be to by using map.

>>> a
[1, 2, 3]
>>> b
[4, 5, 6]
>>> for i,j in map(None,a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

One difference in using map compared to zip is, with zip the length of new list is
same as the length of shortest list. For example:

>>> a
[1, 2, 3, 9]
>>> b
[4, 5, 6]
>>> for i,j in zip(a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

Using map on same data:

>>> for i,j in map(None,a,b):
    ...   print i,j
    ...

    1 4
    2 5
    3 6
    9 None

First, array_length should be an integer and not a string:

array_length = len(array_dates)

Second, your for loop should be constructed using range:

for i in range(array_length):  # Use `xrange` for python 2.

Third, i will increment automatically, so delete the following line:

i += 1

Note, one could also just zip the two lists given that they have the same length:

import csv

dates = ['2020-01-01', '2020-01-02', '2020-01-03']
urls = ['www.abc.com', 'www.cnn.com', 'www.nbc.com']

csv_file_patch = '/path/to/filename.csv'

with open(csv_file_patch, 'w') as fout:
    csv_file = csv.writer(fout, delimiter=';', lineterminator='\n')
    result_array = zip(dates, urls)
    csv_file.writerows(result_array)

precision: Its the total number of digits before or after the radix point. EX: 123.456 here precision is 6.

Scale: Its the total number of digits after the radix point. EX: 123.456 here Scaleis 3

If you just need to insert a new row with a data from another row,

    insert into ORDER_ITEM select * from ORDER_ITEM where ITEM_NUMBER =123;

Is the result of getElementsByClassName an Array?

No

If not, what is it?

As with all DOM methods that return multiple elements, it is a NodeList, see https://developer.mozilla.org/en/DOM/document.getElementsByClassName

concat also works nicely with a list comprehension pulled using the "loc" command against an existing dataframe

df = pd.read_csv('./data.csv') # ie; Dataframe pulled from csv file with a "userID" column

review_ids = ['1','2','3'] # ie; ID values to grab from DataFrame

# Gets rows in df where IDs match in the userID column and combines them 

dfa = pd.concat([df.loc[df['userID'] == x] for x in review_ids])

Change these shortcuts in Visual Studio

Tools ? Options ? Environment ? Keyboard

and then change the command

"Edit.FormatDocument" or "Edit.FormatSelection"

assign the same shortcut alt + shift +f as in visual studio code in order to not remember another one and confuse between each other.

You can also define these chars as list of string. Then you can check if the characters is valid for accepted characters with list.Contains(x) method.

Thanks to all for your help - I was off this issue for a couple of days and just came back to it - was able to cobble this together - not the most elegant code, but it works for my purposes - thought I'd share if anyone else encounters this issue:

I had the same problem so I came up with this script that just lists the md5sums of the files in the directory and if it finds a subdirectory it runs again from there, for this to happen the script has to be able to run through the current directory or from a subdirectory if said argument is passed in $1

#!/bin/bash

if [ -z "$1" ] ; then

# loop in current dir
ls | while read line; do
  ecriv=`pwd`"/"$line
if [ -f $ecriv ] ; then
    md5sum "$ecriv"
elif [ -d $ecriv ] ; then
    sh myScript "$line" # call this script again
fi

done


else # if a directory is specified in argument $1

ls "$1" | while read line; do
  ecriv=`pwd`"/$1/"$line

if [ -f $ecriv ] ; then
    md5sum "$ecriv"

elif [ -d $ecriv ] ; then
    sh myScript "$line"
fi

done


fi

For me the easiest way to get it to work, is to put the component.requestFocus(); line, after the setVisible(true); line, at the bottom of your frame or panel constructor.

This probably has something to do with asking for the focus, after all components have been created, because creating a new component, after asking for the focus request, will make your component loose te focus, and make the focus go to your newly created component. At least, that's what I assume.

Also on OS X (El Capitan), been having this same issue all morning.

I was running the command "npm install -g grunt-cli" command from within a directory where my project was.

I tried again from my home directory (i.e. 'cd ~') and it installed as before, except now I can run the grunt command and it is recognised.

I hope this will help.

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

Super easy way is as following. No need to create a function.

<select onchange="window.location = this.options[this.selectedIndex].value">
    <option value="">Switch Language</option>
    <option value="{{ url('/en') }}">English</option>
    <option value="{{ url('/ps') }}">????</option>
    <option value="{{ url('/fa') }}">???</option>
</select>

A simple approach which returns a string with ip-addresses for the interfaces is:

from subprocess import check_output

ips = check_output(['hostname', '--all-ip-addresses'])

for more info see hostname.

One great thing about unit tests is that they serve as documentation for how your code is meant to behave. Good tests are kind of like a reference implementation, and teammates can look at them to see how to integrate their code with yours.

My issue turned out to be in the Publish settings in Visual Studio. My appsettings.json connection string was correct, but the Database connection strings in the publish settings, had integrated security = true.

I use this Function I modified (the Days part) From @Dane answer: https://stackoverflow.com/a/57720/2097023

CREATE FUNCTION dbo.EdadAMD
    (
        @FECHA DATETIME
    )
    RETURNS NVARCHAR(10)
    AS
    BEGIN
        DECLARE

          , @months  INT
          , @days    INT
          , @EdadAMD NVARCHAR(10);

        SELECT @tmpdate = @FECHA;

        SELECT @years = DATEDIFF(yy, @tmpdate, GETDATE()) - CASE
                                          WHEN (MONTH(@FECHA) >    MONTH(GETDATE()))
                                             OR (

It works pretty well.

Merge Array with Push:

const array1 = [2, 7, 4];_x000D_
const array2 = [3, 5,9];_x000D_
array1.push(...array2);_x000D_
console.log(array1)

Using Concat and Spread operator:

const array1 = [1,2];_x000D_
const array2 = [3,4];_x000D_
_x000D_
// Method 1: Concat _x000D_
const combined1 = [].concat(array1, array2);_x000D_
_x000D_
// Method 2: Spread_x000D_
const combined2 = [...array1, ...array2];_x000D_
_x000D_
console.log(combined1);_x000D_
console.log(combined2);

In general, the best practice recommendation is singular, except for those enums that have the [Flags] attribute attached to them, (and which therefore can contain bit fields), which should be plural.

After reading your edited question, I get the feeling you may think the property name or variable name has to be different from the enum type name... It doesn't. The following is perfectly fine...

  public enum Status { New, Edited, Approved, Cancelled, Closed }

  public class Order
  {
      private Status stat;
      public Status Status
      { 
         get { return stat; }
         set { stat = value; }
      }
  }

Late simple example:

from os import path, getcwd, chdir

def print_my_path():
    print('cwd:     {}'.format(getcwd()))
    print('__file__:{}'.format(__file__))
    print('abspath: {}'.format(path.abspath(__file__)))

print_my_path()

chdir('..')

print_my_path()

Under Python-2.*, the second call incorrectly determines the path.abspath(__file__) based on the current directory:

cwd:     C:\codes\py
__file__:cwd_mayhem.py
abspath: C:\codes\py\cwd_mayhem.py
cwd:     C:\codes
__file__:cwd_mayhem.py
abspath: C:\codes\cwd_mayhem.py

As noted by @techtonik, in Python 3.4+, this will work fine since __file__ returns an absolute path.

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

You cannot access a local directory from pl/sql. If you use bfile, you will setup a directory (create directory) on the server where Oracle is running where you will need to put your images.

If you want to insert a handful of images from your local machine, you'll need a client side app to do this. You can write your own, but I typically use Toad for this. In schema browser, click onto the table. Click the data tab, and hit + sign to add a row. Double click the BLOB column, and a wizard opens. The far left icon will load an image into the blob:

SQL Developer has a similar feature. See the "Load" link below:

If you need to pull images over the wire, you can do it using pl/sql, but its not straight forward. First, you'll need to setup ACL list access (for security reasons) to allow a user to pull over the wire. See this article for more on ACL setup.

Assuming ACL is complete, you'd pull the image like this:

declare
    l_url varchar2(4000) := 'http://www.oracleimg.com/us/assets/12_c_navbnr.jpg';
    l_http_request   UTL_HTTP.req;
    l_http_response  UTL_HTTP.resp;
    l_raw RAW(2000);
    l_blob BLOB;
begin
   -- Important: setup ACL access list first!

    DBMS_LOB.createtemporary(l_blob, FALSE);

    l_http_request  := UTL_HTTP.begin_request(l_url);
    l_http_response := UTL_HTTP.get_response(l_http_request);

  -- Copy the response into the BLOB.
  BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 2000);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
  EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
  END;

  insert into my_pics (pic_id, pic) values (102, l_blob);
  commit;

  DBMS_LOB.freetemporary(l_blob); 
end;

Hope that helps.

A catch-block in a try statement needs to catch exactly the exception that the code inside the try {}-block can throw (or a super class of that).

try {
    //do something that throws ExceptionA, e.g.
    throw new ExceptionA("I am Exception Alpha!");
}
catch(ExceptionA e) {
    //do something to handle the exception, e.g.
    System.out.println("Message: " + e.getMessage());
}

What you are trying to do is this:

try {
    throw new ExceptionB("I am Exception Bravo!");
}
catch(ExceptionA e) {
    System.out.println("Message: " + e.getMessage());
}

This will lead to an compiler error, because your java knows that you are trying to catch an exception that will NEVER EVER EVER occur. Thus you would get: exception ExceptionA is never thrown in body of corresponding try statement.

You need to manually delete the children. the <condition> is the same for both queries.

DELETE FROM child
FROM cTable AS child
INNER JOIN table AS parent ON child.ParentId = parent.ParentId
WHERE <condition>;

DELETE FROM parent
FROM table AS parent
WHERE <condition>;

The limit of requests in .Net can be configured from two properties together:

The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:

/*jshint -W106 */
save_state(id);
/*jshint +W106 */

Not sure if this is the most efficient way, but:

>>> ''.join(c for c in "abc123def456" if c.isdigit())
'123456'

The ''.join part means to combine all the resulting characters together without any characters in between. Then the rest of it is a list comprehension, where (as you can probably guess) we only take the parts of the string that match the condition isdigit.

You want to replace it, not strip it:

s = s.replace(',', '')

This code has language support. I had used them in Android App.

String[] mons = new DateFormatSymbols().getShortMonths();//Jan,Feb,Mar,... 

String[] months = new DateFormatSymbols().getMonths();//January,Februaty,March,...

You can get that error if you have an object with the same name as the schema. For example:

create sequence s2;

begin
  s2.a;
end;
/

ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

When you refer to S2.MY_FUNC2 the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2 there is no confusion, so it works.

The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.

It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.

select owner, object_type, object_name
from all_objects
where object_name = 'S2';

Javascript is a multi-paradigm language that supports procedural, object-oriented (prototype-based) and functional programming styles.

Here is an article discussing how to do OO in Javascript.

I was facing the same issue in bitbucket, and this worked for me:

line1

line2

Same problem for me on apache http client 4.5.5 adding default header

Connection: close

resolve the problem

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

You can use this:

r'[a-z]+(?:-[a-z]+)*' 

You can let the user set a read-only property by providing it through the constructor:

public class Person
{
    public Person(int id)
    {
        this.Id = id;
    }

    public string Name { get;  set; }
    public int Id { get; private set; }
    public int Age { get; set; }
}

I think the best place to look is the Super POM.

As an example, at the time of writing, the linked reference shows some of the properties between lines 32 - 48.

The interpretation of this is to follow the XPath as a . delimited property.

So, for example:

${project.build.testOutputDirectory} == ${project.build.directory}/test-classes

And:

${project.build.directory} == ${project.basedir}/target

Thus combining them, we find:

${project.build.testOutputDirectory} == ${project.basedir}/target/test-classes

(To reference the resources directory(s), see this stackoverflow question)

<project>
    <modelVersion>4.0.0</modelVersion>
    .
    .
    .
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>
        <finalName>${project.artifactId}-${project.version}</finalName>
        <testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <scriptSourceDirectory>src/main/scripts</scriptSourceDirectory>

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.

get_or_create() returns a tuple:

customer.source, created  = Source.objects.get_or_create(name="Website")

• created ? has a boolean value, is created or not.

• customer.source ? has an object of get_or_create() method.

Most of the other answers seem to be db specific.

General SQL query should be as follows:

select
   sal 
from
   emp a 
where
   N = (
      select
         count(distinct sal) 
      from
         emp b 
      where
         a.sal <= b.sal
   )
where
   N = any value

and this query should be able to work on any database.

What you expect is the synchronous (blocking) type request.

var it_works = false;

jQuery.ajax({
  type: "POST",
  url: 'some_file.php',
  success: function (data) {
    it_works = true;
  }, 
  async: false // <- this turns it into synchronous
});?

// Execution is BLOCKED until request finishes.

// it_works is available
alert(it_works);

Requests are asynchronous (non-blocking) by default which means that the browser won't wait for them to be completed in order to continue its work. That's why your alert got wrong result.

Now, with jQuery.ajax you can optionally set the request to be synchronous, which means that the script will only continue to run after the request is finished.

The RECOMMENDED way, however, is to refactor your code so that the data would be passed to a callback function as soon as the request is finished. This is preferred because blocking execution means blocking the UI which is unacceptable. Do it this way:

$.post("some_file.php", '', function(data) {
    iDependOnMyParameter(data);
});

function iDependOnMyParameter(param) {
    // You should do your work here that depends on the result of the request!
    alert(param)
}

// All code here should be INDEPENDENT of the result of your AJAX request
// ...

Asynchronous programming is slightly more complicated because the consequence of making a request is encapsulated in a function instead of following the request statement. But the realtime behavior that the user experiences can be significantly better because they will not see a sluggish server or sluggish network cause the browser to act as though it had crashed. Synchronous programming is disrespectful and should not be employed in applications which are used by people.

Maven

The Answer by Bhesh Gurung is correct… unless your NetBeans project is Maven based.

Dependency

Under Maven, you add a "dependency". A dependency is a description of a library (its name & version number) you want to use from your code.

Or a dependency could be a description of a library which another library needs ("depends on"). Maven automatically handles this chain, libraries that need other libraries that then need other libraries and so on. For the mathematical-minded, perhaps the phrase "Maven resolves the transitive dependencies" makes sense.

Repository

Maven gets this related-ness information, and the libraries themselves from a Maven repository. A repository is basically an online database and collection of download files (the dependency library).

Easy to Use

Adding a dependency to a Maven-based project is really quite easy. That is the whole point to Maven, to make managing dependent libraries easy and to make building them into your project easy. To get started with adding a dependency, see this Question, Adding dependencies in Maven Netbeans and my Answer with screenshot.

There are two file in C:\Program Files\Android\Android Studio\bin. studio and studio64. I was running studio while my system is 64 bit. when I ran studio64 it worked. My system variable are

JAVA_HOME = C:\Program Files\Java\jdk-10.0.2;.;
JDK_HOME = C:\Program Files\Java\jdk-10.0.2;.;
PATH = C:\Program Files\Android\Android Studio\jre\jre\bin;.;

I think this code should work fine

while ($personCount < 10) {
$result = $personCount . "people ';
$personCount++;
}
// do not understand why do you need the (+) with the result.
echo $result;

i have made a simple program, where you have 2 txt field you take input form the user and add them to make it simpler to understand please find the code below.

@IBOutlet weak var result: UILabel!
@IBOutlet weak var one: UITextField!
@IBOutlet weak var two: UITextField!

@IBAction func add(sender: AnyObject) {        
    let count = Int(one.text!)
    let cal = Int(two.text!)
    let sum = count! + cal!
    result.text = "Sum is \(sum)"
}

hope this helps.

Here a complete example :

Suppose we have a Person class like :

public class Person
{
    protected String fname;
    protected String lname;

    public Person()
    {

    }

    public Person(String fname, String lname)
    {
        this.fname = fname;
        this.lname = lname;
    }

    public boolean equals(Object objet)
    {
        if(objet instanceof Person)
        {
            Person p = (Person) objet;
            return (p.getFname().equals(this.fname)) && p.getLname().equals(this.lname));
        }
        else return super.equals(objet);
    }

    @Override
    public String toString()
    {
        return "Person(fname : " + getFname + ", lname : " + getLname + ")";
    }

    /** Getters and Setters **/
}

Now we create a comparator :

import java.util.Comparator;

public class ComparePerson implements Comparator<Person>
{
    @Override
    public int compare(Person p1, Person p2)
    {
        if(p1.getFname().equalsIgnoreCase(p2.getFname()))
        {
            return p1.getLname().compareTo(p2.getLname());
        }
        return p1.getFname().compareTo(p2.getFname());
    }
}

Finally suppose we have a group of persons :

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class Group
{
    protected List<Person> listPersons;

    public Group()
    {
        this.listPersons = new ArrayList<Person>();
    }

    public Group(List<Person> listPersons)
    {
        this.listPersons = listPersons;
    }

    public void order(boolean asc)
    {
        Comparator<Person> comp = asc ? new ComparePerson() : Collections.reverseOrder(new ComparePerson());
        Collections.sort(this.listPersons, comp);
    }

    public void display()
    {
        for(Person p : this.listPersons)
        {
            System.out.println(p);
        }
    }

    /** Getters and Setters **/
}

Now we try this :

import java.util.ArrayList;
import java.util.List;

public class App
{
    public static void main(String[] args)
    {
        Group g = new Group();
        List listPersons = new ArrayList<Person>();
        g.setListPersons(listPersons);

        Person p;

        p = new Person("A", "B");
        listPersons.add(p);

        p = new Person("C", "D");
        listPersons.add(p);

        /** you can add Person as many as you want **/

        g.display();

        g.order(true);
        g.display();

        g.order(false);
        g.display();
    }
}

hey I think that you just copy your compiled class files and copy the jre folder and make the following as the content of the batch file and save all together any windows machine and just double click

@echo
setpath d:\jre
d:
cd myprogfolder
java myprogram

Use JSON.stringify:

> JSON.stringify({ asd: 'bla' });
'{"asd":"bla"}'

You can use the Tanuki wrapper to spawn a process with POSIX spawn instead of fork. http://wrapper.tanukisoftware.com/doc/english/child-exec.html

The WrapperManager.exec() function is an alternative to the Java-Runtime.exec() which has the disadvantage to use the fork() method, which can become on some platforms very memory expensive to create a new process.

try this:

.test {
    position:absolute;
    background:blue;
    width:200px;
    height:200px;
    top:40px;
    transition:left 1s linear;
    left: 0;
}

The problem is that your ApplicationUser inherits from IdentityUser, which is defined like this:

IdentityUser : IdentityUser<string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUser
....
public virtual ICollection<TRole> Roles { get; private set; }
public virtual ICollection<TClaim> Claims { get; private set; }
public virtual ICollection<TLogin> Logins { get; private set; }

and their primary keys are mapped in the method OnModelCreating of the class IdentityDbContext:

modelBuilder.Entity<TUserRole>()
            .HasKey(r => new {r.UserId, r.RoleId})
            .ToTable("AspNetUserRoles");

modelBuilder.Entity<TUserLogin>()
            .HasKey(l => new {l.LoginProvider, l.ProviderKey, l.UserId})
            .ToTable("AspNetUserLogins");

and as your DXContext doesn't derive from it, those keys don't get defined.

If you dig into the sources of Microsoft.AspNet.Identity.EntityFramework, you will understand everything.

I came across this situation some time ago, and I found three possible solutions (maybe there are more):

1. Use separate DbContexts against two different databases or the same database but different tables.
2. Merge your DXContext with ApplicationDbContext and use one database.
3. Use separate DbContexts against the same table and manage their migrations accordingly.

Option 1: See update the bottom.

Option 2: You will end up with a DbContext like this one:

public class DXContext : IdentityDbContext<User, Role,
    int, UserLogin, UserRole, UserClaim>//: DbContext
{
    public DXContext()
        : base("name=DXContext")
    {
        Database.SetInitializer<DXContext>(null);// Remove default initializer
        Configuration.ProxyCreationEnabled = false;
        Configuration.LazyLoadingEnabled = false;
    }

    public static DXContext Create()
    {
        return new DXContext();
    }

    //Identity and Authorization
    public DbSet<UserLogin> UserLogins { get; set; }
    public DbSet<UserClaim> UserClaims { get; set; }
    public DbSet<UserRole> UserRoles { get; set; }
    
    // ... your custom DbSets
    public DbSet<RoleOperation> RoleOperations { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();

        // Configure Asp Net Identity Tables
        modelBuilder.Entity<User>().ToTable("User");
        modelBuilder.Entity<User>().Property(u => u.PasswordHash).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.Stamp).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.PhoneNumber).HasMaxLength(50);

        modelBuilder.Entity<Role>().ToTable("Role");
        modelBuilder.Entity<UserRole>().ToTable("UserRole");
        modelBuilder.Entity<UserLogin>().ToTable("UserLogin");
        modelBuilder.Entity<UserClaim>().ToTable("UserClaim");
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimType).HasMaxLength(150);
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimValue).HasMaxLength(500);
    }
}

Option 3: You will have one DbContext equal to the option 2. Let's name it IdentityContext. And you will have another DbContext called DXContext:

public class DXContext : DbContext
{        
    public DXContext()
        : base("name=DXContext") // connection string in the application configuration file.
    {
        Database.SetInitializer<DXContext>(null); // Remove default initializer
        Configuration.LazyLoadingEnabled = false;
        Configuration.ProxyCreationEnabled = false;
    }

    // Domain Model
    public DbSet<User> Users { get; set; }
    // ... other custom DbSets
    
    public static DXContext Create()
    {
        return new DXContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        // IMPORTANT: we are mapping the entity User to the same table as the entity ApplicationUser
        modelBuilder.Entity<User>().ToTable("User"); 
    }

    public DbQuery<T> Query<T>() where T : class
    {
        return Set<T>().AsNoTracking();
    }
}

where User is:

public class User
{
    public int Id { get; set; }

    [Required, StringLength(100)]
    public string Name { get; set; }

    [Required, StringLength(128)]
    public string SomeOtherColumn { get; set; }
}

With this solution, I'm mapping the entity User to the same table as the entity ApplicationUser.

Then, using Code First Migrations you'll need to generate the migrations for the IdentityContext and THEN for the DXContext, following this great post from Shailendra Chauhan: Code First Migrations with Multiple Data Contexts

You'll have to modify the migration generated for DXContext. Something like this depending on which properties are shared between ApplicationUser and User:

        //CreateTable(
        //    "dbo.User",
        //    c => new
        //        {
        //            Id = c.Int(nullable: false, identity: true),
        //            Name = c.String(nullable: false, maxLength: 100),
        //            SomeOtherColumn = c.String(nullable: false, maxLength: 128),
        //        })
        //    .PrimaryKey(t => t.Id);
        AddColumn("dbo.User", "SomeOtherColumn", c => c.String(nullable: false, maxLength: 128));

and then running the migrations in order (first the Identity migrations) from the global.asax or any other place of your application using this custom class:

public static class DXDatabaseMigrator
{
    public static string ExecuteMigrations()
    {
        return string.Format("Identity migrations: {0}. DX migrations: {1}.", ExecuteIdentityMigrations(),
            ExecuteDXMigrations());
    }

    private static string ExecuteIdentityMigrations()
    {
        IdentityMigrationConfiguration configuration = new IdentityMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string ExecuteDXMigrations()
    {
        DXMigrationConfiguration configuration = new DXMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string RunMigrations(DbMigrationsConfiguration configuration)
    {
        List<string> pendingMigrations;
        try
        {
            DbMigrator migrator = new DbMigrator(configuration);
            pendingMigrations = migrator.GetPendingMigrations().ToList(); // Just to be able to log which migrations were executed

            if (pendingMigrations.Any())                
                    migrator.Update();     
        }
        catch (Exception e)
        {
            ExceptionManager.LogException(e);
            return e.Message;
        }
        return !pendingMigrations.Any() ? "None" : string.Join(", ", pendingMigrations);
    }
}

This way, my n-tier cross-cutting entities don't end up inheriting from AspNetIdentity classes, and therefore I don't have to import this framework in every project where I use them.

Sorry for the extensive post. I hope it could offer some guidance on this. I have already used options 2 and 3 in production environments.

UPDATE: Expand Option 1

For the last two projects I have used the 1st option: having an AspNetUser class that derives from IdentityUser, and a separate custom class called AppUser. In my case, the DbContexts are IdentityContext and DomainContext respectively. And I defined the Id of the AppUser like this:

public class AppUser : TrackableEntity
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
    // This Id is equal to the Id in the AspNetUser table and it's manually set.
    public override int Id { get; set; }

(TrackableEntity is the custom abstract base class that I use in the overridden SaveChanges method of my DomainContext context)

I first create the AspNetUser and then the AppUser. The drawback with this approach is that you have ensured that your "CreateUser" functionality is transactional (remember that there will be two DbContexts calling SaveChanges separately). Using TransactionScope didn't work for me for some reason, so I ended up doing something ugly but that works for me:

        IdentityResult identityResult = UserManager.Create(aspNetUser, model.Password);

        if (!identityResult.Succeeded)
            throw new TechnicalException("User creation didn't succeed", new LogObjectException(result));

        AppUser appUser;
        try
        {
            appUser = RegisterInAppUserTable(model, aspNetUser);
        }
        catch (Exception)
        {
            // Roll back
            UserManager.Delete(aspNetUser);
            throw;
        }

(Please, if somebody comes with a better way of doing this part I appreciate commenting or proposing an edit to this answer)

The benefits are that you don't have to modify the migrations and you can use any crazy inheritance hierarchy over the AppUser without messing with the AspNetUser. And actually, I use Automatic Migrations for my IdentityContext (the context that derives from IdentityDbContext):

public sealed class IdentityMigrationConfiguration : DbMigrationsConfiguration<IdentityContext>
{
    public IdentityMigrationConfiguration()
    {
        AutomaticMigrationsEnabled = true;
        AutomaticMigrationDataLossAllowed = false;
    }

    protected override void Seed(IdentityContext context)
    {
    }
}

This approach also has the benefit of avoiding to have your n-tier cross-cutting entities inheriting from AspNetIdentity classes.

One issue I've had, and it was horribly tricky, was that the OCI call to describe a column attributes behaves diffrently depending on Oracle versions. Describing a simple NUMBER column created without any prec or scale returns differenlty on 9i, 1Og and 11g

@glglgl already explained why what you were trying to do was not working. Actually, if you are really aiming at defining a variable in a header, you can trick using some preprocessor directives:

file1.c:

#include <stdio.h>

#define DEFINE_I
#include "global.h"

int main()
{
    printf("%d\n",i);
    foo();
    return 0;
}

file2.c:

#include <stdio.h>
#include "global.h"

void foo()
{
    i = 54;
    printf("%d\n",i);
}

global.h:

#ifdef DEFINE_I
int i = 42;
#else
extern int i;
#endif

void foo();

In this situation, i is only defined in the compilation unit where you defined DEFINE_I and is declared everywhere else. The linker does not complain.

I have seen this a couple of times before where an enum was declared in a header, and just below was a definition of a char** containing the corresponding labels. I do understand why the author preferred to have that definition in the header instead of putting it into a specific source file, but I am not sure whether the implementation is so elegant.

When you run composer update, composer generates a file called composer.lock which lists all your packages and the currently installed versions. This allows you to later run composer install, which will install the packages listed in that file, recreating the environment that you were last using.

It appears from your log that some of the versions of packages that are listed in your composer.lock file are no longer available. Thus, when you run composer install, it complains and fails. This is usually no big deal - just run composer update and it will attempt to build a set of packages that work together and write a new composer.lock file.

However, you're running into a different problem. It appears that, in your composer.json file, the original developer has added some pre- or post- update actions that are failing, specifically a php artisan migrate command. This can be avoided by running the following: composer update --no-scripts

This will run the composer update but will skip over the scripts added to the file. You should be able to successfully run the update this way.

However, this does not solve the problem long-term. There are two problems:

1. A migration is for database changes, not random stuff like compiling assets. Go through the migrations and remove that code from there.

2. Assets should not be compiled each time you run composer update. Remove that step from the composer.json file.

From what I've read, best practice seems to be compiling assets on an as-needed basis during development (ie. when you're making changes to your LESS files - ideally using a tool like gulp.js) and before deployment.

DECLARE @str AS VARCHAR(50)
SET @str = 'PONIES!!...pon1es!!...p0n1es!!'

IF PATINDEX('%[0-9]%', @str) > 0
   PRINT 'YES, The string has numbers'
ELSE
   PRINT 'NO, The string does not have numbers' 

Here is simple code for calculator so you can consider this
import java.util.*;
import java.util.Scanner;
public class Hello {
    public static void main(String[] args)
    {
        System.out.println("Enter first and second number:");
        Scanner inp= new Scanner(System.in);
        int num1,num2;
        num1 = inp.nextInt();
        num2 = inp.nextInt();
        int ans;
        System.out.println("Enter your selection: 1 for Addition, 2 for substraction 3 for Multiplication and 4 for division:");
        int choose;
        choose = inp.nextInt();
        switch (choose){
        case 1:
            System.out.println(add( num1,num2));
            break;
        case 2:
            System.out.println(sub( num1,num2));
            break;      
        case 3:
            System.out.println(mult( num1,num2));
            break;
        case 4:
            System.out.println(div( num1,num2));
            break;
            default:
                System.out.println("Illigal Operation");


        }



    }
    public static int add(int x, int y)
    {
        int result = x + y;
        return result;
    }
    public static int sub(int x, int y)
    {
        int result = x-y;
        return result;
    }
    public static int mult(int x, int y)
    {
        int result = x*y;
        return result;
    }
    public static int div(int x, int y)
    {
        int result = x/y;
        return result;
    }

}

To display the item number on the repeater you can use the Container.ItemIndex property.

<asp:repeater id="rptRepeater" runat="server">
    <itemtemplate>
        Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
    </itemtemplate>
    <separatortemplate>
        <br />
    </separatortemplate>
</asp:repeater>

1. First, check existing mode(s) are using the following command in your terminal:

   $ mysql -u root -p -e "SHOW VARIABLES LIKE 'sql_mode';"

   or

   mysql> show variables like 'sql_mode';

   You would see an output like below

   

2. Disable mode(s) via my.cnf: In this case, you need to remove NO_ZERO_IN_DATE, NO_ZERO_DATE modes

   Open my.cnf file (Generally you could find my.cnf file located in /etc/my.cnf or /etc/mysql/my.cnf)

   Update modes in my.cnf under [mysqld] heading

   sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

   Here I have omitted NO_ZERO_IN_DATE, NO_ZERO_DATE modes

3. Restart mysql server

   $ /etc/init.d/mysql restart

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

The raw_input() function reads a line from input (i.e. the user) and returns a string

Python v3.x as raw_input() was renamed to input()

PEP 3111: raw_input() was renamed to input(). That is, the new input() function reads a line from sys.stdin and returns it with the trailing newline stripped. It raises EOFError if the input is terminated prematurely. To get the old behavior of input(), use eval(input()).

Ref: Docs Python 3

TLDR for people comming from c++

It's just overloaded operator of ( ) parentheses

So in scala:

class X {
   def apply(param1: Int, param2: Int, param3: Int) : Int = {
     // Do something
   }
}

Is same as this in c++:

class X {
   int operator()(int param1, int param2, int param3) {
      // do something
   }
};

I'm surprised nobody mentioned this. You can tether via Bluetooth, and separate them by ten+ meters(or less with obstacles). You've got a real bad connection. No microwave, no elevator, no software needed.

Microsoft Identity has extension methods which call async methods synchronously. For example there is GenerateUserIdentityAsync() method and equal CreateIdentity()

If you look at UserManagerExtensions.CreateIdentity() it look like this:

 public static ClaimsIdentity CreateIdentity<TUser, TKey>(this UserManager<TUser, TKey> manager, TUser user,
        string authenticationType)
        where TKey : IEquatable<TKey>
        where TUser : class, IUser<TKey>
    {
        if (manager == null)
        {
            throw new ArgumentNullException("manager");
        }
        return AsyncHelper.RunSync(() => manager.CreateIdentityAsync(user, authenticationType));
    }

Now lets see what AsyncHelper.RunSync does

  public static TResult RunSync<TResult>(Func<Task<TResult>> func)
    {
        var cultureUi = CultureInfo.CurrentUICulture;
        var culture = CultureInfo.CurrentCulture;
        return _myTaskFactory.StartNew(() =>
        {
            Thread.CurrentThread.CurrentCulture = culture;
            Thread.CurrentThread.CurrentUICulture = cultureUi;
            return func();
        }).Unwrap().GetAwaiter().GetResult();
    }

So, this is your wrapper for async method. And please don't read data from Result - it will potentially block your code in ASP.

There is another way - which is suspicious for me, but you can consider it too

  Result r = null;

            YourAsyncMethod()
                .ContinueWith(t =>
                {
                    r = t.Result;
                })
                .Wait();

My solution :

select h.hostid, sum(ifnull(h.A,0)) as A, sum(ifnull(h.B,0)) as B, sum(ifnull(h.C,0)) as  C from (
select
hostid,
case when itemName = 'A' then itemvalue end as A,
case when itemName = 'B' then itemvalue end as B,
case when itemName = 'C' then itemvalue end as C
  from history 
) h group by hostid

It produces the expected results in the submitted case.

I see a couple of issues.

First:

ser.read() is only going to return 1 byte at a time.

If you specify a count

ser.read(5)

it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)

If you know that your input is always properly terminated with EOL characters, better way is to use

ser.readline()

That will continue to read characters until an EOL is received.

Second:

Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.

Get rid of the

for line in ser.read():

and just say:

line = ser.readline()

UPDATE: Use Dependabot - https://dependabot.com/docker/

BLUF: finding the right insertion point for monitoring changes to a container is the challenge. It would be great if DockerHub would solve this. (Repository Links have been mentioned but note when setting them up on DockerHub - "Trigger a build in this repository whenever the base image is updated on Docker Hub. Only works for non-official images.")

While trying to solve this myself I saw several recommendations for webhooks so I wanted to elaborate on a couple of solutions I have used.

1. Use microbadger.com to track changes in a container and use it's notification webhook feature to trigger an action. I set this up with zapier.com (but you can use any customizable webhook service) to create a new issue in my github repository that uses Alpine as a base image.

   • Pros: You can review the changes reported by microbadger in github before taking action.
   • Cons: Microbadger doesn't let you track a specific tag. Looks like it only tracks 'latest'.

2. Track the RSS feed for git commits to an upstream container. ex. https://github.com/gliderlabs/docker-alpine/commits/rootfs/library-3.8/x86_64. I used zapier.com to monitor this feed and to trigger an automatic build of my container in Travis-CI anytime something is committed. This is a little extreme but you can change the trigger to do other things like open an issue in your git repository for manual intervention.

   • Pros: Closer to an automated pipline. The Travis-CI build just checks to see if your container has issues with whatever was committed to the base image repository. It's up to you if your CI service takes any further action.
   • Cons: Tracking the commit feed isn't perfect. Lots of things get committed to the repository that don't affect the build of the base image. Doesn't take in to account any issues with frequency/number of commits and any API throttling.

I think you should look at this link ... you can make a mixed key using several identifiers such as mac+os+hostname+cpu id+motherboard serial number.

You can use insert to specify where you want to new column to be. In this case, I use 0 to place the new column at the left.

df.insert(0, 'Name', 'abc')

  Name        Date  Open  High  Low  Close
0  abc  01-01-2015   565   600  400    450

Note: This is some explanation and pseudocode as to how to implement a very trivial server that can handle incoming and outcoming WebSocket messages as per the definitive framing format. It does not include the handshaking process. Furthermore, this answer has been made for educational purposes; it is not a full-featured implementation.

Specification (RFC 6455)

Sending messages

(In other words, server → browser)

The frames you're sending need to be formatted according to the WebSocket framing format. For sending messages, this format is as follows:

• one byte which contains the type of data (and some additional info which is out of scope for a trivial server)
• one byte which contains the length
• either two or eight bytes if the length does not fit in the second byte (the second byte is then a code saying how many bytes are used for the length)
• the actual (raw) data

The first byte will be 1000 0001 (or 129) for a text frame.

The second byte has its first bit set to 0 because we're not encoding the data (encoding from server to client is not mandatory).

It is necessary to determine the length of the raw data so as to send the length bytes correctly:

• if 0 <= length <= 125, you don't need additional bytes
• if 126 <= length <= 65535, you need two additional bytes and the second byte is 126
• if length >= 65536, you need eight additional bytes, and the second byte is 127

The length has to be sliced into separate bytes, which means you'll need to bit-shift to the right (with an amount of eight bits), and then only retain the last eight bits by doing AND 1111 1111 (which is 255).

After the length byte(s) comes the raw data.

This leads to the following pseudocode:

bytesFormatted[0] = 129

indexStartRawData = -1 // it doesn't matter what value is
                       // set here - it will be set now:

if bytesRaw.length <= 125
    bytesFormatted[1] = bytesRaw.length

    indexStartRawData = 2

else if bytesRaw.length >= 126 and bytesRaw.length <= 65535
    bytesFormatted[1] = 126
    bytesFormatted[2] = ( bytesRaw.length >> 8 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length      ) AND 255

    indexStartRawData = 4

else
    bytesFormatted[1] = 127
    bytesFormatted[2] = ( bytesRaw.length >> 56 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length >> 48 ) AND 255
    bytesFormatted[4] = ( bytesRaw.length >> 40 ) AND 255
    bytesFormatted[5] = ( bytesRaw.length >> 32 ) AND 255
    bytesFormatted[6] = ( bytesRaw.length >> 24 ) AND 255
    bytesFormatted[7] = ( bytesRaw.length >> 16 ) AND 255
    bytesFormatted[8] = ( bytesRaw.length >>  8 ) AND 255
    bytesFormatted[9] = ( bytesRaw.length       ) AND 255

    indexStartRawData = 10

// put raw data at the correct index
bytesFormatted.put(bytesRaw, indexStartRawData)


// now send bytesFormatted (e.g. write it to the socket stream)

Receiving messages

(In other words, browser → server)

The frames you obtain are in the following format:

• one byte which contains the type of data
• one byte which contains the length
• either two or eight additional bytes if the length did not fit in the second byte
• four bytes which are the masks (= decoding keys)
• the actual data

The first byte usually does not matter - if you're just sending text you are only using the text type. It will be 1000 0001 (or 129) in that case.

The second byte and the additional two or eight bytes need some parsing, because you need to know how many bytes are used for the length (you need to know where the real data starts). The length itself is usually not necessary since you have the data already.

The first bit of the second byte is always 1 which means the data is masked (= encoded). Messages from the client to the server are always masked. You need to remove that first bit by doing secondByte AND 0111 1111. There are two cases in which the resulting byte does not represent the length because it did not fit in the second byte:

• a second byte of 0111 1110, or 126, means the following two bytes are used for the length
• a second byte of 0111 1111, or 127, means the following eight bytes are used for the length

The four mask bytes are used for decoding the actual data that has been sent. The algorithm for decoding is as follows:

decodedByte = encodedByte XOR masks[encodedByteIndex MOD 4]

where encodedByte is the original byte in the data, encodedByteIndex is the index (offset) of the byte counting from the first byte of the real data, which has index 0. masks is an array containing of the four mask bytes.

This leads to the following pseudocode for decoding:

secondByte = bytes[1]

length = secondByte AND 127 // may not be the actual length in the two special cases

indexFirstMask = 2          // if not a special case

if length == 126            // if a special case, change indexFirstMask
    indexFirstMask = 4

else if length == 127       // ditto
    indexFirstMask = 10

masks = bytes.slice(indexFirstMask, 4) // four bytes starting from indexFirstMask

indexFirstDataByte = indexFirstMask + 4 // four bytes further

decoded = new array

decoded.length = bytes.length - indexFirstDataByte // length of real data

for i = indexFirstDataByte, j = 0; i < bytes.length; i++, j++
    decoded[j] = bytes[i] XOR masks[j MOD 4]


// now use "decoded" to interpret the received data

Java Strings are immutable.

In your first example, you are changing the reference to the String, thus assigning it the value of two other Strings combined: str + " Morning".

On the contrary, a StringBuilder or StringBuffer can be modified through its methods.

Kinda late.But it just takes a bit of math.

.content {
  margin-top: 50px;
  background: #777;
  padding: 30px;
  padding-bottom: 0;
  font-size: 11px;
  border: 1px dotted #222;
}

.bottom-content {
  background: #999;
  width: 100%; /* you need this for it to work */
  margin-left: -30px; /* will touch very left side */
  padding-right: 60px; /* will touch very right side */
}

<div class='content'>

  <p>A paragraph</p>
  <p>Another paragraph.</p>
  <p>No more content</p>


  <div class='bottom-content'>
      I want this div to ignore padding.
  </div>

I don't have Windows so I didn't test this in IE.

In A1 of your new sheet, put this:

=OFFSET(Sheet1!$A$1,(ROW()-1)*7,0)

... and copy down. If you start somewhere other than row 1, change ROW() to ROW(A1) or some other cell on row 1, then copy down again.

If you want to copy the nth line but multiple columns, use the formula:

=OFFSET(Sheet1!A$1,(ROW()-1)*7,0)

This can be copied right too.

$num_result = mysql_query("SELECT count(*) as total_count from Students ") or exit(mysql_error());
$row = mysql_fetch_object($num_result);
echo $row->total_count;

We have multiple volumes per drive (some are mounted on subdirectories on the drive). This code shows a list of the mount points and volume labels. Obviously you can also extract free space and so on:

gwmi win32_volume|where-object {$_.filesystem -match "ntfs"}|sort {$_.name} |foreach-object {
  echo "$(echo $_.name) [$(echo $_.label)]"
}

To post form data with fetch api, try this code it works for me ^_^

function card(fileUri) {
let body = new FormData();
let formData = new FormData();
formData.append('file', fileUri);

fetch("http://X.X.X.X:PORT/upload",
  {
      body: formData,
      method: "post"
  });
 }

Assuming a list like below - and assuming some of the options were selected ... (this is a multi select, but this will also work on a single select.

<select multiple='multiple' id='selectListName'> 
    <option>1</option> 
    <option>2</option> 
    <option>3</option> 
    <option>4</option>
</select>

In some function called based on some event, the following code would clear all selected options.

$("#selectListName").prop('selectedIndex', -1);

Use gettimeofday() or better clock_gettime()

This was an old question, but existing answers ignore the serious issue of throwing away any custom attributes when you regenerate the model. I am adding a more detailed answer to cover the current options available.

You have 3 options:

• Add a [DisplayName("Name goes here")] attribute to the data model class. The downside is that this is thrown away whenever you regenerate the data models.
• Add a string parameter to your Html.LabelFor. e.g. @Html.LabelFor(model => model.SomekingStatus, "My New Label", new { @class = "control-label"}) Reference: https://msdn.microsoft.com/en-us/library/system.web.mvc.html.labelextensions.labelfor(v=vs.118).aspx The downside to this is that you must repeat the label in every view.
• Third option. Use a meta-data class attached to the data class (details follow).

Option 3 - Add a Meta-Data Class:

Microsoft allows for decorating properties on an Entity Framework class, without modifying the existing class! This by having meta-data classes that attach to your database classes (effectively a sideways extension of your EF class). This allow attributes to be added to the associated class and not to the class itself so the changes are not lost when you regenerate the data models.

For example, if your data class is MyModel with a SomekingStatus property, you could do it like this:

First declare a partial class of the same name (and using the same namespace), which allows you to add a class attribute without being overridden:

[MetadataType(typeof(MyModelMetaData))]
public partial class MyModel
{
}

All generated data model classes are partial classes, which allow you to add extra properties and methods by simply creating more classes of the same name (this is very handy and I often use it e.g. to provide formatted string versions of other field types in the model).

Step 2: add a metatadata class referenced by your new partial class:

public class MyModelMetaData
{
    // Apply DisplayNameAttribute (or any other attributes)
    [DisplayName("My New Label")]
    public string SomekingStatus;
}

Reference: https://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.metadatatypeattribute(v=vs.110).aspx

Notes:

• From memory, if you start using a metadata class, it may ignore existing attributes on the actual class ([required] etc) so you may need to duplicate those in the Meta-data class.
• This does not operate by magic and will not just work with any classes. The code that looks for UI decoration attributes is designed to look for a meta-data class first.

Had the same problem.

I just ran the query and checked:

firefox: 18

.squaredcorners {
    -moz-appearance: none;
}

\s means "one space", and \s+ means "one or more spaces".

But, because you're using the /g flag (replace all occurrences) and replacing with the empty string, your two expressions have the same effect.

For Each is much faster than for I=1 to X, for some reason. Just try to go through the same dictionary,

once with for each Dkey in dDict,

and once with for Dkey = lbound(dDict.keys) to ubound(dDict.keys)

=>You will notice a huge difference, even though you are going through the same construct.

I was facing the same issue, after trying most of the methods mentioned above I couldn't get the solution. In my case the issue of because of Github changing the name of master to main branch.

Go to Setting -> go to GitHub Pages section and change the branch to main:

as posted by @randymohan, with using statements instead

public static void WriteLog(string strLog)
{
    string logFilePath = @"C:\Logs\Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";
    FileInfo logFileInfo = new FileInfo(logFilePath);
    DirectoryInfo logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
    if (!logDirInfo.Exists) logDirInfo.Create();
    using (FileStream fileStream = new FileStream(logFilePath, FileMode.Append))
    {
        using (StreamWriter log = new StreamWriter(fileStream))
        {
            log.WriteLine(strLog);

}

Standard approach:

from collections import defaultdict

words = "apple banana apple strawberry banana lemon"
words = words.split()
result = defaultdict(int)
for word in words:
    result[word] += 1

print result

Groupby oneliner:

from itertools import groupby

words = "apple banana apple strawberry banana lemon"
words = words.split()

result = dict((key, len(list(group))) for key, group in groupby(sorted(words)))
print result

There is the Jquery alert plugin

$.alerts.okButton = ' Yes ';
$.alerts.cancelButton = ' No ';

Boris Zbarsky (Mozilla), who probably knows more about the innards of Gecko than anyone else, provided at http://lists.w3.org/Archives/Public/public-html/2009Apr/0195.html the pseudocode repeated below to describe what Gecko based browsers do:

Regarding a NodeJS implementation, I have added a custom expiryTime field in the object I save in the HASH. Then after a specific period time, I clear the expired HASH entries by using the following code:

client.hgetall(HASH_NAME, function(err, reply) {
    if (reply) {
        Object.keys(reply).forEach(key => {
            if (reply[key] && JSON.parse(reply[key]).expiryTime < (new Date).getTime()) {
                client.hdel(HASH_NAME, key);
            }
        })
    }
});

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/

Use element.outerHTML to get full representation of element, including outer tags and attributes.

From my recent experience, JsonReader#setLenient basically makes the parser very tolerant, even to allow malformed JSON data.

But for certain data retrieved from your trusted RESTful API(s), this error might be caused by trailing white spaces. In such cases, simply trim the data would avoid the error:

String trimmed = result1.trim();

Then gson.fromJson(trimmed, T) might work. Surely this only covers a special case, so YMMV.

I know this doesn't meet the helper function requirement, but the way I've done this is using jQuery's $.each() method

var loginForm = $('.login').serializeArray();
var loginFormObject = {};
$.each(loginForm,
    function(i, v) {
        loginFormObject[v.name] = v.value;
    });

Then I can pass loginFormObject to my backend, or you could create a userobject and save() it in backbone as well.

As an alternative to James McNellis answer, I always try to use enumeration for the bool type instead of macros: typedef enum bool {false=0; true=1;} bool;. It is safer b/c it lets the compiler do type checking and eliminates macro expansion races

Did a little research on this, it appears that you are looping from 1 to 2147483647, in increments of 1.

(1, 1, 2147483647): The firs number is the starting number, the next number is the step, and the last number is the end number.

Edited To Add

It appears that the loop runs to completion regardless of any test conditions. I tested

FOR /L %%F IN (1, 1, 5) DO SET %%F=6

And it ran very quickly.

Second Edit

Since this is the only line in the batch file, you might try the EXIT command:

FOR /L %%F IN (1, 1, 2147483647) DO @IF NOT EXIST %%F EXIT

However, this will also close the DOS prompt window.

You can use routerLink which is an alternative of href for angular 2.** Use routerLink as below in html

<a routerLink="/dashboard">My Link</a>

and make sure you register your routerLink in modules.ts or router.ts like this

const routes: Routes = [
  { path: 'dashboard', component: DashboardComponent }
]

Use $ne instead of $not

http://docs.mongodb.org/manual/reference/operator/ne/#op._S_ne

db.collections.find({"name": {$ne: ""}});

Try this in your constructor

MainActivity maniActivity = (MainActivity)context;
EditText firstName = (EditText) maniActivity.findViewById(R.id.display_name);

Although the prior answer by brunsgaard is an efficient encoding, it works only for unsigned integers. This one builds upon it to work for both signed and unsigned integers.

def int_to_bytes(i: int, *, signed: bool = False) -> bytes:
    length = ((i + ((i * signed) < 0)).bit_length() + 7 + signed) // 8
    return i.to_bytes(length, byteorder='big', signed=signed)

def bytes_to_int(b: bytes, *, signed: bool = False) -> int:
    return int.from_bytes(b, byteorder='big', signed=signed)

# Test unsigned:
for i in range(1025):
    assert i == bytes_to_int(int_to_bytes(i))

# Test signed:
for i in range(-1024, 1025):
    assert i == bytes_to_int(int_to_bytes(i, signed=True), signed=True)

For the encoder, (i + ((i * signed) < 0)).bit_length() is used instead of just i.bit_length() because the latter leads to an inefficient encoding of -128, -32768, etc.

Use <br> tags

<div class="container">

If anyone is looking into this, I've been trying different options and the following approach yields very good results. The following are the steps to get a working example:

1. Add .NET Wrapper for tesseract to your project. It can be added via NuGet package Install-Package Tesseract(https://github.com/charlesw/tesseract).
2. Go to the Downloads section of the official Tesseract project (https://code.google.com/p/tesseract-ocr/ EDIT: It's now located here: https://github.com/tesseract-ocr/langdata).
3. Download the preferred language data, example: tesseract-ocr-3.02.eng.tar.gz English language data for Tesseract 3.02.
4. Create tessdata directory in your project and place the language data files in it.
5. Go to Properties of the newly added files and set them to copy on build.
6. Add a reference to System.Drawing.
7. From .NET Wrapper repository, in the Samples directory copy the sample phototest.tif file into your project directory and set it to copy on build.
8. Create the following two files in your project (just to get started):

Program.cs

using System;
using Tesseract;
using System.Diagnostics;

namespace ConsoleApplication
{
    class Program
    {
        public static void Main(string[] args)
        {
            var testImagePath = "./phototest.tif";
            if (args.Length > 0)
            {
                testImagePath = args[0];
            }

            try
            {
                var logger = new FormattedConsoleLogger();
                var resultPrinter = new ResultPrinter(logger);
                using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
                {
                    using (var img = Pix.LoadFromFile(testImagePath))
                    {
                        using (logger.Begin("Process image"))
                        {
                            var i = 1;
                            using (var page = engine.Process(img))
                            {
                                var text = page.GetText();
                                logger.Log("Text: {0}", text);
                                logger.Log("Mean confidence: {0}", page.GetMeanConfidence());

                                using (var iter = page.GetIterator())
                                {
                                    iter.Begin();
                                    do
                                    {
                                        if (i % 2 == 0)
                                        {
                                            using (logger.Begin("Line {0}", i))
                                            {
                                                do
                                                {

                                                    {
                                                        if (iter.IsAtBeginningOf(PageIteratorLevel.Block))

                                                        }
                                                        if (iter.IsAtBeginningOf(PageIteratorLevel.Para))
                                                        {
                                                            logger.Log("New paragraph");
                                                        }
                                                        if (iter.IsAtBeginningOf(PageIteratorLevel.TextLine))
                                                        {
                                                            logger.Log("New line");

I used the Debug "app" button
and my problem was solved

Perhaps I didn't see the answer, but this is how I do it.

1. .Net Core --> Properties --> launchSettings.json

You need to have change these values

"windowsAuthentication": true, // needs to be true
"anonymousAuthentication": false,  // needs to be false 

Startup.cs --> ConfigureServices(...)

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

MVC or Web Api Controller

private readonly IHttpContextAccessor _httpContextAccessor;
//constructor then
_httpContextAccessor = httpContextAccessor;

Controller method:

string userName = _httpContextAccessor.HttpContext.User.Identity.Name;

Result is userName e.g. = Domain\username

str = "/folderA/folderB/folderC/folderD/"
print str.split("/")[-2]

The error for me was that the project did not have any branches created, and my role was developer, so I could not create any branch, request that they give me the pertinent permissions and everything in order now!

I know you asked about C#, but if you're willing to use any .Net language then I highly recommend Visual Basic for this exact problem. Visual Basic has a feature called XML Literals that will allow you to write code like this.

Module Module1

    Sub Main()

        Dim myTitle = "Hello HTML"
        Dim myHTML = <html>
                         <head>
                             <title><%= myTitle %></title>
                         </head>
                         <body>
                             <h1>Welcome</h1>
                             <table>
                                 <tr><th>ID</th><th>Name</th></tr>
                                 <tr><td>1</td><td>CouldBeAVariable</td></tr>
                             </table>
                         </body>
                     </html>

        Console.WriteLine(myHTML)
    End Sub

End Module

This allows you to write straight HTML with expression holes in the old ASP style and makes your code super readable. Unfortunately this feature is not in C#, but you could write a single module in VB and add it as a reference to your C# project.

Writing in Visual Studio also allows proper indentation for most XML Literals and expression wholes. Indentation for the expression holes is better in VS2010.
