This script works!

#/bin/bash
if [[ ( "$#" < 1 ) || ( !( "$1" == 1 ) && !( "$1" == 0 ) ) ]] ; then
    echo this script requires a 1 or 0 as first parameter.
else
    echo "first parameter is $1"
    xinput set-prop 12 "Device Enabled" $0
fi

But this also works, and in addition keeps the logic of the OP, since the question is about calculations. Here it is with only arithmetic expressions:

#/bin/bash
if (( $# )) && (( $1 == 0 || $1 == 1 )); then
    echo "first parameter is $1"
    xinput set-prop 12 "Device Enabled" $0
else
    echo this script requires a 1 or 0 as first parameter.
fi

The output is the same¹:

$ ./tmp.sh 
this script requires a 1 or 0 as first parameter.

$ ./tmp.sh 0
first parameter is 0

$ ./tmp.sh 1
first parameter is 1

$ ./tmp.sh 2
this script requires a 1 or 0 as first parameter.

_{[1] the second fails if the first argument is a string}

To get public static void main(String[] args) line in eclipse without typing the whole line type "main" and press Ctrl + space then, you will get the option for the main method select it.

Return ABDeadlineType from repository:

public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {
    List<ABDeadlineType> findAllSummarizedBy();
}

and then convert to DeadlineType. Manually or use mapstruct.

Or call constructor from @Query annotation:

public interface DeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {

    @Query("select new package.DeadlineType(a.id, a.code) from ABDeadlineType a ")
    List<DeadlineType> findAllSummarizedBy();
}

Or use @Projection:

@Projection(name = "deadline", types = { ABDeadlineType.class })
public interface DeadlineType {

    @Value("#{target.id}")
    String getId();

    @Value("#{target.code}")
    String getText();

}

Update: Spring can work without @Projection annotation:

public interface DeadlineType {
    String getId();    
    String getText();
}

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

If you want to apply some condition on form submit then you can use this method

<form onsubmit="return checkEmpData();" method="post" action="process.html">
  <input type="text" border="0" name="submit" />
  <button value="submit">submit</button>
</form>

One thing always keep in mind that method and action attribute write after onsubmit attributes

javascript code

function checkEmpData()
{
  var a = 0;

  if(a != 0)
  {
    return confirm("Do you want to generate attendance?");
  }
   else
   {
      alert('Please Select Employee First');
      return false;
   }  
}

The other case involving print >>obj, "Hello World" is the "print chevron" syntax for the print statement in Python 2 (removed in Python 3, replaced by the file argument of the print() function). Instead of writing to standard output, the output is passed to the obj.write() method. A typical example would be file objects having a write() method. See the answer to a more recent question: Double greater-than sign in Python.

You can use DataFrame.select_dtypes to select string columns and then apply function str.strip.

Notice: Values cannot be types like dicts or lists, because their dtypes is object.

df_obj = df.select_dtypes(['object'])
print (df_obj)
0    a  
1    c  

df[df_obj.columns] = df_obj.apply(lambda x: x.str.strip())
print (df)

   0   1
0  a  10
1  c   5

But if there are only a few columns use str.strip:

df[0] = df[0].str.strip()

They need to be percent-encoded:

> encodeURIComponent('&')
"%26"

So in your case, the URL would look like:

http://www.mysite.com?candy_name=M%26M

Create your own UUID and then store it in the Keychain. Thus it persists even when your app gets uninstalled. In many cases it also persists even if the user migrates between devices (e.g. full backup and restore to another device).

Effectively it becomes a unique user identifier as far as you're concerned. (even better than device identifier).

Example:

I am defining a custom method for creating a UUID as :

- (NSString *)createNewUUID 
{
    CFUUIDRef theUUID = CFUUIDCreate(NULL);
    CFStringRef string = CFUUIDCreateString(NULL, theUUID);
    CFRelease(theUUID);
    return [(NSString *)string autorelease];
}

You can then store it in KEYCHAIN on the very first launch of your app. So that after first launch, we can simply use it from keychain, no need to regenerate it. The main reason for using Keychain to store is: When you set the UUID to the Keychain, it will persist even if the user completely uninstalls the App and then installs it again. . So, this is the permanent way of storing it, which means the key will be unique all the way.

     #import "SSKeychain.h"
     #import <Security/Security.h>

On applictaion launch include the following code :

 // getting the unique key (if present ) from keychain , assuming "your app identifier" as a key
       NSString *retrieveuuid = [SSKeychain passwordForService:@"your app identifier" account:@"user"];
      if (retrieveuuid == nil) { // if this is the first time app lunching , create key for device
        NSString *uuid  = [self createNewUUID];
// save newly created key to Keychain
        [SSKeychain setPassword:uuid forService:@"your app identifier" account:@"user"];
// this is the one time process
}

Download SSKeychain.m and .h file from sskeychain and Drag SSKeychain.m and .h file to your project and add "Security.framework" to your project. To use UUID afterwards simply use :

NSString *retrieveuuid = [SSKeychain passwordForService:@"your app identifier" account:@"user"];

Well, deleting an element from array is basically just set difference with one element.

array_diff( [312, 401, 15, 401, 3], [401] ) // removing 401 returns [312, 15, 3]

It generalizes nicely, you can remove as many elements as you like at the same time, if you want.

Disclaimer: Note that my solution produces a new copy of the array while keeping the old one intact in contrast to the accepted answer which mutates. Pick the one you need.

If you want to check the version of a specific Kafka broker, run this CLI on the broker*

kafka-broker-api-versions.sh --bootstrap-server localhost:9092 --version

where localhost:9092 is the accessible <hostname|IP Address>:<port> this API will check (localhost can be used if it's the same host you're running this command on). Example of output:

2.4.0 (Commit:77a89fcf8d7fa018)

* Apache Kafka comes with a variety of console tools in the ./bin sub-directory of your Kafka download; e.g. ~/kafka/bin/

Jar( Java Archive) contains group of .class files.

1.To create Jar File (Zip File)

 if one .class (say, Demo.class) then use command jar -cvf NameOfJarFile.jar Demo.class (usually it’s not feasible for only one .class file)

 if more than one .class (say, Demo.class , DemoOne.class) then use command jar -cvf NameOfJarFile.jar Demo.class DemoOne.class

 if all .class is to be group (say, Demo.class , DemoOne.class etc) then use command jar -cvf NameOfJarFile.jar *.class

2.To extract Jar File (Unzip File)

    jar -xvf NameOfJarFile.jar

3.To display table of content

    jar -tvf NameOfJarFile.jar

Kotlin one-liner

etxt_userinput.filters = arrayOf<InputFilter>(InputFilter.LengthFilter(100))

where 100 is the maxLength

If you want to extract the hours, minutes and seconds, try this:

String inputDate = "12:00:00";
String[] split = inputDate.split(":");
int hours = Integer.valueOf(split[0]);
int minutes = Integer.valueOf(split[1]);
int seconds = Integer.valueOf(split[2]);

This bookmarlet works in Google sites/Youtube as of Aug 2019 (tested in Chrome and Firefox):

javascript: function enableContextMenu(aggressive = false) { void(document.ondragstart=null); void(document.onselectstart=null); void(document.onclick=null); void(document.onmousedown=null); void(document.onmouseup=null); void(document.body.oncontextmenu=null); enableRightClickLight(document); if (aggressive) { enableRightClick(document); removeContextMenuOnAll("body"); removeContextMenuOnAll("img"); removeContextMenuOnAll("td"); } } function removeContextMenuOnAll(tagName) { var elements = document.getElementsByTagName(tagName); for (var i = 0; i < elements.length; i++) { enableRightClick(elements[i]); } } function enableRightClickLight(el) { el || (el = document); el.addEventListener("contextmenu", bringBackDefault, true); } function enableRightClick(el) { el || (el = document); el.addEventListener("contextmenu", bringBackDefault, true); el.addEventListener("dragstart", bringBackDefault, true); el.addEventListener("selectstart", bringBackDefault, true); el.addEventListener("click", bringBackDefault, true); el.addEventListener("mousedown", bringBackDefault, true); el.addEventListener("mouseup", bringBackDefault, true); } function restoreRightClick(el) { el || (el = document); el.removeEventListener("contextmenu", bringBackDefault, true); el.removeEventListener("dragstart", bringBackDefault, true); el.removeEventListener("selectstart", bringBackDefault, true); el.removeEventListener("click", bringBackDefault, true); el.removeEventListener("mousedown", bringBackDefault, true); el.removeEventListener("mouseup", bringBackDefault, true); } function bringBackDefault(event) { event.returnValue = true; (typeof event.stopPropagation === 'function') && event.stopPropagation(); (typeof event.cancelBubble === 'function') && event.cancelBubble(); } enableContextMenu();

For peskier sites, set/pass aggressive to true (this will disable most event handlers and hence disable interaction with the page):

javascript: function enableContextMenu(aggressive = true) { void(document.ondragstart=null); void(document.onselectstart=null); void(document.onclick=null); void(document.onmousedown=null); void(document.onmouseup=null); void(document.body.oncontextmenu=null); enableRightClickLight(document); if (aggressive) { enableRightClick(document); removeContextMenuOnAll("body"); removeContextMenuOnAll("img"); removeContextMenuOnAll("td"); } } function removeContextMenuOnAll(tagName) { var elements = document.getElementsByTagName(tagName); for (var i = 0; i < elements.length; i++) { enableRightClick(elements[i]); } } function enableRightClickLight(el) { el || (el = document); el.addEventListener("contextmenu", bringBackDefault, true); } function enableRightClick(el) { el || (el = document); el.addEventListener("contextmenu", bringBackDefault, true); el.addEventListener("dragstart", bringBackDefault, true); el.addEventListener("selectstart", bringBackDefault, true); el.addEventListener("click", bringBackDefault, true); el.addEventListener("mousedown", bringBackDefault, true); el.addEventListener("mouseup", bringBackDefault, true); } function restoreRightClick(el) { el || (el = document); el.removeEventListener("contextmenu", bringBackDefault, true); el.removeEventListener("dragstart", bringBackDefault, true); el.removeEventListener("selectstart", bringBackDefault, true); el.removeEventListener("click", bringBackDefault, true); el.removeEventListener("mousedown", bringBackDefault, true); el.removeEventListener("mouseup", bringBackDefault, true); } function bringBackDefault(event) { event.returnValue = true; (typeof event.stopPropagation === 'function') && event.stopPropagation(); (typeof event.cancelBubble === 'function') && event.cancelBubble(); } enableContextMenu();

I ran into a similar issue. To check if SELinux is the problem, one can check its running status with

sestatus

and temporarily disable it with

setenforce 0

This could at least help to narrow down the problem.

Your HTML and the way you call the function from the button look correct.

The problem appears to be in the CapacityCount function. I'm getting this error in my console on Firefox 3.5: "document.all is undefined" on line 759 of bendelcorp.js.

Edit:

Looks like document.all is an IE-only thing and is a nonstandard way of accessing the DOM. If you use document.getElementById(), it should probably work. Example: document.getElementById("RUnits").value instead of document.all.Capacity.RUnits.value

Lots of great answers here but I feel like I can add my own because of simplicity, performance (comparing to resource-related solutions) cross platform (works with Net Core too) and avoidance of any 3rd party tool. Just add this msbuild target to the csproj.

<Target Name="Date" BeforeTargets="CoreCompile">
    <WriteLinesToFile File="$(IntermediateOutputPath)gen.cs" Lines="static partial class Builtin { public static long CompileTime = $([System.DateTime]::UtcNow.Ticks) %3B }" Overwrite="true" />
    <ItemGroup>
        <Compile Include="$(IntermediateOutputPath)gen.cs" />
    </ItemGroup>
</Target>

and now you have Builtin.CompileTime or new DateTime(Builtin.CompileTime, DateTimeKind.Utc) if you need it that way.

ReSharper is not gonna like it. You can ignore him or add a partial class to the project too but it works anyway.

Single quotes are for a single character. Double quotes are for a string (array of characters). You can use single quotes to build up a string one character at a time, if you like.

char myChar     = 'A';
char myString[] = "Hello Mum";
char myOtherString[] = { 'H','e','l','l','o','\0' };

I recommend php-ffmpeg library.

Extracting image

You can extract a frame at any timecode using the FFMpeg\Media\Video::frame method.

This code returns a FFMpeg\Media\Frame instance corresponding to the second 42. You can pass any FFMpeg\Coordinate\TimeCode as argument, see dedicated documentation below for more information.

$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(42));
$frame->save('image.jpg');

If you want to extract multiple images from the video, you can use the following filter:

$video
    ->filters()
    ->extractMultipleFrames(FFMpeg\Filters\Video\ExtractMultipleFramesFilter::FRAMERATE_EVERY_10SEC, '/path/to/destination/folder/')
    ->synchronize();

$video
    ->save(new FFMpeg\Format\Video\X264(), '/path/to/new/file');

By default, this will save the frames as jpg images.

You are able to override this using setFrameFileType to save the frames in another format:

$frameFileType = 'jpg'; // either 'jpg', 'jpeg' or 'png'
$filter = new ExtractMultipleFramesFilter($frameRate, $destinationFolder);
$filter->setFrameFileType($frameFileType);

$video->addFilter($filter);

Try this command:

Dism.exe /online /enable-feature /featurename:NetFX3 /Source:I:\Sources\sxs /LimitAccess

I: partition of your Windows DVD.

If you want 08:30 ( HH:MM) format then try this,

SELECT EmplID
    , EmplName
    , InTime
    , [TimeOut]
    , [DateVisited]
    ,  RIGHT('0' + CONVERT(varchar(3),DATEDIFF(minute,InTime, TimeOut)/60),2) + ':' +
      RIGHT('0' + CONVERT(varchar(2),DATEDIFF(minute,InTime,TimeOut)%60),2)
      as TotalHours from times Order By EmplID, DateVisited

Apple push will reject a string for a variety of reasons. I tested a variety of scenarios for push delivery, and this was my working fix (in python):

#  Apple rejects push payloads > 256 bytes (truncate msg to < 120 bytes to be safe)
if len(push_str) > 120:
    push_str = push_str[0:120-3] + '...'

# Apple push rejects all quotes, remove them
import re
push_str = re.sub("[\"']", '', push_str)

# Apple push needs to newlines escaped
import MySQLdb
push_str = MySQLdb.escape_string(push_str)

# send it
import APNSWrapper
wrapper = APNSWrapper.APNSNotificationWrapper(certificate=...)
message = APNSWrapper.APNSNotification()
message.token(...)
message.badge(1)
message.alert(push_str)
message.sound("default")
wrapper.append(message)
wrapper.notify()

This is not to check for null, instead this will be helpful in converting an existing object to an empty object(fresh object). I dont know whether this is relevant or not, but I had such a requirement.

@SuppressWarnings({ "unchecked" })
static void emptyObject(Object obj) 
{
    Class c1 = obj.getClass();
    Field[] fields = c1.getDeclaredFields();

    for(Field field : fields)
    {
        try
        {
            if(field.getType().getCanonicalName() == "boolean")
            {
                field.set(obj, false);
            }
            else if(field.getType().getCanonicalName() == "char")
            {
                field.set(obj, '\u0000');
            }
            else if((field.getType().isPrimitive()))
            {
                field.set(obj, 0);
            }
            else
            {
                field.set(obj, null);
            }
        }
        catch(Exception ex)
        {

        }
    }
}

Here is working code for converting an image from a base64 string to an Image object and storing it in a folder with unique file name:

public void SaveImage()
{
    string strm = "R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"; 

    //this is a simple white background image
    var myfilename= string.Format(@"{0}", Guid.NewGuid());

    //Generate unique filename
    string filepath= "~/UserImages/" + myfilename+ ".jpeg";
    var bytess = Convert.FromBase64String(strm);
    using (var imageFile = new FileStream(filepath, FileMode.Create))
    {
        imageFile.Write(bytess, 0, bytess.Length);
        imageFile.Flush();
    }
}

You can add one

public static boolean isNullOrBlank(String param) { 
    return param == null || param.trim().length() == 0;
}

I have

public static boolean isSet(String param) { 
    // doesn't ignore spaces, but does save an object creation.
    return param != null && param.length() != 0; 
}

In SSMS, you can't print new line with select, just using PRINT instead

DECLARE @text NVARCHAR(100)
SET @text = concat(N'This is line 1.', CHAR(10), N'This is line 2.')
PRINT @text

For Android developers who couldn't get it fixed by just closing and rebuilding, Manually uninstall the app on the emulator/device.

UIAlertView is deprecated on iOS 8. Therefore, to create an alert on iOS 8 and above, it is recommended to use UIAlertController:

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"Alert Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    // Enter code here
}];
[alert addAction:defaultAction];

// Present action where needed
[self presentViewController:alert animated:YES completion:nil];

This is how I have implemented it.

You should check that what you are passing to foreach is an array by using the is_array function

If you are not sure it's going to be an array you can always check using the following PHP example code:

if (is_array($variable)) {

  foreach ($variable as $item) {
   //do something
  }
}

I did downgrade the node version from 12 to 10

EDIT

This error occurred with me because I was using node version 12. When I downgrade to version 10.16.5 this error stops. This error happened in my local env, but in prod and staging, it not happens. In prod and staging node version is 10.x so I just do this and I didn't need to update any package in my package.json

The problem with UTF-8 is that it is not the most space efficient encoding. Also, some random binary byte sequences are invalid UTF-8 encoding. So you can't just interpret a random binary byte sequence as some UTF-8 data because it will be invalid UTF-8 encoding. The benefit of this constrain on the UTF-8 encoding is that it makes it robust and possible to locate multi byte chars start and end whatever byte we start looking at.

As a consequence, if encoding a byte value in the range [0..127] would need only one byte in UTF-8 encoding, encoding a byte value in the range [128..255] would require 2 bytes ! Worse than that. In JSON, control chars, " and \ are not allowed to appear in a string. So the binary data would require some transformation to be properly encoded.

Let see. If we assume uniformly distributed random byte values in our binary data then, on average, half of the bytes would be encoded in one bytes and the other half in two bytes. The UTF-8 encoded binary data would have 150% of the initial size.

Base64 encoding grows only to 133% of the initial size. So Base64 encoding is more efficient.

What about using another Base encoding ? In UTF-8, encoding the 128 ASCII values is the most space efficient. In 8 bits you can store 7 bits. So if we cut the binary data in 7 bit chunks to store them in each byte of an UTF-8 encoded string, the encoded data would grow only to 114% of the initial size. Better than Base64. Unfortunately we can't use this easy trick because JSON doesn't allow some ASCII chars. The 33 control characters of ASCII ( [0..31] and 127) and the " and \ must be excluded. This leaves us only 128-35 = 93 chars.

So in theory we could define a Base93 encoding which would grow the encoded size to 8/log2(93) = 8*log10(2)/log10(93) = 122%. But a Base93 encoding would not be as convenient as a Base64 encoding. Base64 requires to cut the input byte sequence in 6bit chunks for which simple bitwise operation works well. Beside 133% is not much more than 122%.

This is why I came independently to the common conclusion that Base64 is indeed the best choice to encode binary data in JSON. My answer presents a justification for it. I agree it isn't very attractive from the performance point of view, but consider also the benefit of using JSON with it's human readable string representation easy to manipulate in all programming languages.

If performance is critical than a pure binary encoding should be considered as replacement of JSON. But with JSON my conclusion is that Base64 is the best.

It's perfect time to try zsh, an (almost) bash superset, with many additional nice features including floating point math. Here is what your example would be like in zsh:

I wrote two using statements inside a try/catch block and I could see the exception was being caught the same way if it's placed within the inner using statement just as ShaneLS example.

     try
     {
       using (var con = new SqlConnection(@"Data Source=..."))
       {
         var cad = "INSERT INTO table VALUES (@r1,@r2,@r3)";

         using (var insertCommand = new SqlCommand(cad, con))
         {
           insertCommand.Parameters.AddWithValue("@r1", atxt);
           insertCommand.Parameters.AddWithValue("@r2", btxt);
           insertCommand.Parameters.AddWithValue("@r3", ctxt);
           con.Open();
           insertCommand.ExecuteNonQuery();
         }
       }
     }
     catch (Exception ex)
     {
       MessageBox.Show("Error: " + ex.Message, "UsingTest", MessageBoxButtons.OK, MessageBoxIcon.Error);
     }

No matter where's the try/catch placed, the exception will be caught without issues.

I had the same. Script been underlined. I added a reference to System.Web.Extensions. Thereafter the Script was no longer underlined. Hope this helps someone.

Well, char (or its wrapper class Character) means a single character, i.e. you can't write 'ab' whereas String is a text consisting of a number of characters and you can think of a string a an array of characters (in fact the String class has a member char[] value).

You could work with plain char arrays but that's quite tedious and thus the String class is there to provide a convenient way for working with texts.

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

I had the very same problem. And as many other posts reported: the padding trick only works for IE.

font-size:0px still shows some small dots.

The only thing that worked for me is doing the opposite

font-size:999px

... but I only had buttons of 25x25 pixels.

Please read this official blog entry on Google developer blog: http://android-developers.blogspot.be/2011/03/identifying-app-installations.html

Conclusion For the vast majority of applications, the requirement is to identify a particular installation, not a physical device. Fortunately, doing so is straightforward.

There are many good reasons for avoiding the attempt to identify a particular device. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices

jQuery transit will probably make your life easier if you are dealing with CSS3 animations through jQuery.

EDIT March 2014 (because my advice has constantly been up and down voted since I posted it)

Let me explain why I was initially hinting towards the plugin above:

Updating the DOM on each step (i.e. $.animate ) is not ideal in terms of performance. It works, but will most probably be slower than pure CSS3 transitions or CSS3 animations.

This is mainly because the browser gets a chance to think ahead if you indicate what the transition is going to look like from start to end.

To do so, you can for example create a CSS class for each state of the transition and only use jQuery to toggle the animation state.

This is generally quite neat as you can tweak you animations alongside the rest of your CSS instead of mixing it up with your business logic:

// initial state
.eye {
   -webkit-transform: rotate(45deg);
   -moz-transform: rotate(45deg);
   transform: rotate(45deg);
   // etc.

   // transition settings
   -webkit-transition: -webkit-transform 1s linear 0.2s;
   -moz-transition: -moz-transform 1s linear 0.2s;
   transition: transform 1s linear 0.2s;
   // etc.
}

// open state    
.eye.open {

   transform: rotate(90deg);
}

// Javascript
$('.eye').on('click', function () { $(this).addClass('open'); });

If any of the transform parameters is dynamic you can of course use the style attribute instead:

$('.eye').on('click', function () { 
    $(this).css({ 
        -webkit-transition: '-webkit-transform 1s ease-in',
        -moz-transition: '-moz-transform 1s ease-in',
        // ...

        // note that jQuery will vendor prefix the transform property automatically
        transform: 'rotate(' + (Math.random()*45+45).toFixed(3) + 'deg)'
    }); 
});

A lot more detailed information on CSS3 transitions on MDN.

HOWEVER There are a few other things to keep in mind and all this can get a bit tricky if you have complex animations, chaining etc. and jQuery Transit just does all the tricky bits under the hood:

$('.eye').transit({ rotate: '90deg'}); // easy huh ?

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

Try this

Sub Txt2Col()
    Dim rng As Range

    Set rng = [C7]
    Set rng = Range(rng, Cells(Rows.Count, rng.Column).End(xlUp))

    rng.TextToColumns Destination:=rng, DataType:=xlDelimited, ' rest of your settings

Update: button click event to act on another sheet

Private Sub CommandButton1_Click()
    Dim rng As Range
    Dim sh As Worksheet

    Set sh = Worksheets("Sheet2")
    With sh
        Set rng = .[C7]
        Set rng = .Range(rng, .Cells(.Rows.Count, rng.Column).End(xlUp))

        rng.TextToColumns Destination:=rng, DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote,  _
        ConsecutiveDelimiter:=False, _
        Tab:=False, _
        Semicolon:=False, _
        Comma:=True, 
        Space:=False, 
        Other:=False, _
        FieldInfo:=Array(Array(1, xlGeneralFormat), Array(2, xlGeneralFormat), Array(3, xlGeneralFormat)), _
        TrailingMinusNumbers:=True
    End With
End Sub

Note the .'s (eg .Range) they refer to the With statement object

The way to do this is near the top of the man page

grep -i -A 10 'error data'

this work for me and do not need change any config file

vim --cmd "set encoding=utf8" --cmd "set fileencoding=utf8" fileToOpen

For two way communication with named pipes:

• If you have few processes, you can open two pipes for two directions (processA2ProcessB and processB2ProcessA)
• If you have many processes, you can open in and out pipes for every process (processAin, processAout, processBin, processBout, processCin, processCout etc)
• Or you can go hybrid as always :)

Named pipes are quite easy to implement.

E.g. I implemented a project in C with named pipes, thanks to standart file input-output based communication (fopen, fprintf, fscanf ...) it was so easy and clean (if that is also a consideration).

I even coded them with java (I was serializing and sending objects over them!)

Named pipes has one disadvantage:

• they do not scale on multiple computers like sockets since they rely on filesystem (assuming shared filesystem is not an option)

Same problem as above, but vastly different root. For me, it was that I was hitting an endpoint with an https rewrite rule. Hitting it on http caused the error, worked as expected with https.

Use IsNumeric. It returns true if it's a number or false otherwise.

Public Sub NumTest()
    On Error GoTo MyErrorHandler

    Dim myVar As Variant
    myVar = 11.2 'Or whatever

    Dim finalNumber As Integer
    If IsNumeric(myVar) Then
        finalNumber = CInt(myVar)
    Else
        finalNumber = 0
    End If

    Exit Sub

MyErrorHandler:
    MsgBox "NumTest" & vbCrLf & vbCrLf & "Err = " & Err.Number & _
        vbCrLf & "Description: " & Err.Description
End Sub

You can use a TextFormField instead of TextField, and use the initialValue property. for example

TextFormField(initialValue: "I am smart")

I had encountered the same error with React version 16. This error comes when the Javascript that tries to render the React component is included before the static parent dom element in the html. Fix is same as the accepted answer, i.e. the JavaScript should get included only after the static parent dom element has been defined in the html.

Do it java 8 way in just 1 line:

String.join("", arr);

If you are trying to bind is a Model class, you can add a new readonly property to it like:

public string FormattedPercentage
{
    get
    {
        If(this.Percentage < 50)
            return "0 %";
        else 
            return string.Format("{0} %", this.Percentage)        
     }
}

Otherwise you can use Andrei's or kostas ch. suggestions if you cannot modify the class itself

If you want to return IHttpActionResult you can do it like this:

[HttpGet]
public IHttpActionResult Test()
{
    var stream = new MemoryStream();

    var result = new HttpResponseMessage(HttpStatusCode.OK)
    {
        Content = new ByteArrayContent(stream.GetBuffer())
    };
    result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
    {
        FileName = "test.pdf"
    };
    result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

    var response = ResponseMessage(result);

    return response;
}

Giving an element the attribute readonly will give that element the readonly status. It doesn't matter what value you put after it or if you put any value after it, it will still see it as readonly. Putting readonly="false" won't work.

Suggested is to use the W3C standard, which is readonly="readonly".

Replace:

myBinding.Source = ViewModel.SomeString;

with:

myBinding.Source = ViewModel;

Example:

Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);

Your source should be just ViewModel, the .SomeString part is evaluated from the Path (the Path can be set by the constructor or by the Path property).

Hiding HTML source isn't really possible. Disabling right-click only frustrates users who wish to do something constructive with your content (copy/paste content or forms, or print, for example).

If you're running a server-side scripting language you could obfuscate or minify the HTML, CSS and Javascript. This will make it harder for someone to copy your code or see how you've achieved certain effects.

The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

column of first matrix = row of second matrix

and do not follow the below step

row of first matrix  = column of second matrix

it will throw an error

If you have jQuery, use isPlainObject.

if ($.isPlainObject(my_var)) {}

^{Due to the fact that I answered this in 2014, I have updated my answer to account for more recent versions of ansible.}

Yes, you can do it at the host/inventory level (Which became possible on newer ansible versions) or global level:

inventory:

Add the following.

ansible_ssh_common_args='-o StrictHostKeyChecking=no'

host:

Add the following.

ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

hosts/inventory options will work with connection type ssh and not paramiko. Some people may strongly argue that inventory and hosts is more secure because the scope is more limited.

global:

Ansible User Guide - Host Key Checking

• You can do it either in the /etc/ansible/ansible.cfg or ~/.ansible.cfg file:

  [defaults]
  host_key_checking = False
  

• Or you can setup and env variable (this might not work on newer ansible versions):

  export ANSIBLE_HOST_KEY_CHECKING=False
  

I see most people confused about tf.shape(tensor) and tensor.get_shape() Let's make it clear:

1. tf.shape

tf.shape is used for dynamic shape. If your tensor's shape is changable, use it. An example: a input is an image with changable width and height, we want resize it to half of its size, then we can write something like:
new_height = tf.shape(image)[0] / 2

2. tensor.get_shape

tensor.get_shape is used for fixed shapes, which means the tensor's shape can be deduced in the graph.

Conclusion: tf.shape can be used almost anywhere, but t.get_shape only for shapes can be deduced from graph.

If you want to retrieve the display text of the item, use the GetItemText method:

string text = listBox1.GetItemText(listBox1.SelectedItem);

1. check the list of installed apk's (following command also list the path where it is installed and package name). adb shell pm list packages -f
2. use adb pull /package_path/package name /path_in_pc (package path and package name one can get from above command 1.)

The usage of MAC id is most easier way if the task is about logging the unique id a system.

the change of mac id is though possible, even the change of other ids of a system are also possible is that respective device is replaced.

so, unless what for a unique id is required is not known, we may not be able to find an appropriate solution.

However, the below link is helpful extracting mac addresses. http://www.stratos.me/2008/07/find-mac-address-using-java/

Your code is fine. There's no problem with returning Strings in this manner.

In Java, a String is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String around without worrying that it would disapper on you, or that someone somewhere would modify it.

If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:

public String time_to_string(long t) // time in milliseconds
{
    if (t < 0)
    {
        return "-";
    }
    else
    {
        int secs = (int)(t/1000);
        int mins = secs/60;
        secs = secs - (mins * 60);
        return String.format("%d:%02d", mins, secs);
    }
}

As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans and have replaced the mix of string concatenation and String.format() with a single call to String.format().

Try this in your model:

function order_summary_insert()
    $OrderLines=$this->input->post('orderlines');
    $CustomerName=$this->input->post('customer');
    $data = array(
        'OrderLines'=>$OrderLines,
        'CustomerName'=>$CustomerName
    );

    $this->db->insert('Customer_Orders',$data);
}

Try to use controller just to control the view and models always post your values in model. it makes easy to understand. Your controller will be:

function new_blank_order_summary() {
    $this->sales_model->order_summary_insert($data);
    $this->load->view('sales/new_blank_order_summary');
}

JScript is Microsoft's implementation of the ECMAScript specification. JavaScript is the Mozilla implementation of the specification.

I am assuming that you are making a web app because you refer to Apache and Node. Quick answer - Is it possible - YES. Is it recommended - NO. Node bundles it's own webserver and most websites run on port 80. I am also assuming that there is currently no Apache plugin which is supported by Nodejs and I am not sure if creating a virtual host is the best way to implement this. These are the questions that should be answered by developers who maintain Nodejs like the good folks at Joyent.

Instead of ports, it would be better to evaluate Node's tech stack which is completely different from most others and which is why I love it but it also involves a few compromises that you should be aware of in advance.

Your example looks similar to a CMS or a sharing web app and there are hundreds of out of the box apps available that will run just fine on Apache. Even if you do not like any readymade solution, you could write a webapp in PHP / Java / Python or mix n match it with a couple of ready made apps and they are all designed and supported to run behind a single instance of Apache.

It's time to pause and think about what I just said.

Now you are ready to decide on which techstack you are going to use. If your website will never use any out of the thousands of ready made apps that require Apache, then go for Node otherwise you must first eliminate the assumptions that I have stated earlier.

In the end, your choice of techstack is way more important than any individual component.

I completely agree with @Straseus that it is relatively trivial to use node.js file system api for handling uploads and downloads but think more about what you want from your website in the long run and then choose your techstack.

Learning Node's framework is easier than learning other frameworks but it is not a panacea. With a slightly more effort (which may be a worthwhile endeavor in itself), you can learn any other framework too. We all learn from each other and you will be more productive if you are working as a small team than if you are working alone and your backend technical skills will also develop faster. Therefore, do not discount the skills of other members of your team so cheaply.

This post is about a year old and chances are that you have already decided but I hope that my rant will help the next person who is going through a similar decision.

Thanks for reading.

It's because savefig overrides the facecolor for the background of the figure.

(This is deliberate, actually... The assumption is that you'd probably want to control the background color of the saved figure with the facecolor kwarg to savefig. It's a confusing and inconsistent default, though!)

The easiest workaround is just to do fig.savefig('whatever.png', facecolor=fig.get_facecolor(), edgecolor='none') (I'm specifying the edgecolor here because the default edgecolor for the actual figure is white, which will give you a white border around the saved figure)

Hope that helps!

Adding the jquery*.js file reference twice can also cause the issue. It could be part of your bundle and you might have added to the page too. Hence you need to remove the additional reference like

You should replace your getEnumNameForValue by a call to the name() method.

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

See also:

• ViewParam vs @ManagedProperty(value = "#{param.id}")
• What can <f:metadata>, <f:viewParam> and <f:viewAction> be used for?
• Bookmarkability via View Parameters feature
• How to navigate in JSF? How to make URL reflect current page (and not previous one)

I run a very simple bash script which takes all of 10 seconds to do the job and sends me a mail when done.

#!/bin/bash
sudo service nginx stop
sudo rm -rf /var/cache/nginx/*
sudo service nginx start | mail -s "Nginx Purged" [email protected]
exit 0

Simple to Spit String by Space

    String CurrentString = "First Second Last";
    String[] separated = CurrentString.split(" ");

    for (int i = 0; i < separated.length; i++) {

         if (i == 0) {
             Log.d("FName ** ", "" + separated[0].trim() + "\n ");
         } else if (i == 1) {
             Log.d("MName ** ", "" + separated[1].trim() + "\n ");
         } else if (i == 2) {
             Log.d("LName ** ", "" + separated[2].trim());
         }
     }

You would need to enclose the pattern in a delimiter - typically a slash (/) is used. Try this:

echo preg_replace("/[^0-9]/","",'604-619-5135');

Rather than trying to output to the console, Log will output to LogCat which you can find in Eclipse by going to: Window->Show View->Other…->Android->LogCat

Have a look at the reference for Log.

The benefits of using LogCat are that you can print different colours depending on your log type, e.g.: Log.d prints blue, Log.e prints orange. Also you can filter by log tag, log message, process id and/or by application name. This is really useful when you just want to see your app's logs and keep the other system stuff separate.

Eager Loading When you are sure that want to get multiple entities at a time, for example you have to show user, and user details at the same page, then you should go with eager loading. Eager loading makes single hit on database and load the related entities.

Lazy loading When you have to show users only at the page, and by clicking on users you need to show user details then you need to go with lazy loading. Lazy loading make multiple hits, to get load the related entities when you bind/iterate related entities.

When you start using switch statements within your views, that usually indicate that you can further re-factor your code. Business logic is not meant for views, I would rather suggest you to do the switch statement within your controller and then pass the switch statements outcome to the view.

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

I recommend using the ValueProvider property of the controller, much in the way that UpdateModel/TryUpdateModel do to extract the route, query, and form parameters required. This will keep your method signatures from potentially growing very large and being subject to frequent change. It also makes it a little easier to test since you can supply a ValueProvider to the controller during unit tests.

I think you want this?

Column Name to Column Number

Sub Sample()
    ColName = "C"
    Debug.Print Range(ColName & 1).Column
End Sub

Edit: Also including the reverse of what you want

Column Number to Column Name

Sub Sample()
    ColNo = 3
    Debug.Print Split(Cells(, ColNo).Address, "$")(1)
End Sub

FOLLOW UP

Like if i have salary field at the very top lets say at cell C(1,1) now if i alter the file and shift salary column to some other place say F(1,1) then i will have to modify the code so i want the code to check for Salary and find the column number and then do rest of the operations according to that column number.

In such a case I would recommend using .FIND See this example below

Option Explicit

Sub Sample()
    Dim strSearch As String
    Dim aCell As Range

    strSearch = "Salary"

    Set aCell = Sheet1.Rows(1).Find(What:=strSearch, LookIn:=xlValues, _
    LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
    MatchCase:=False, SearchFormat:=False)

    If Not aCell Is Nothing Then
        MsgBox "Value Found in Cell " & aCell.Address & _
        " and the Cell Column Number is " & aCell.Column
    End If
End Sub

SNAPSHOT

Here is a VB.Net example if you are trying to retrieve the value of a variable from within a page loaded in a WebBrowser control.

Step 1) Add a COM reference in your project to Microsoft HTML Object Library

Step 2) Next, add this VB.Net code to your Form1 to import the mshtml library:
Imports mshtml

Step 3) Add this VB.Net code above your "Public Class Form1" line:
<System.Runtime.InteropServices.ComVisibleAttribute(True)>

Step 4) Add a WebBrowser control to your project

Step 5) Add this VB.Net code to your Form1_Load function:
WebBrowser1.ObjectForScripting = Me

Step 6) Add this VB.Net sub which will inject a function "CallbackGetVar" into the web page's Javascript:

Public Sub InjectCallbackGetVar(ByRef wb As WebBrowser)
    Dim head As HtmlElement
    Dim script As HtmlElement
    Dim domElement As IHTMLScriptElement

    head = wb.Document.GetElementsByTagName("head")(0)
    script = wb.Document.CreateElement("script")
    domElement = script.DomElement
    domElement.type = "text/javascript"
    domElement.text = "function CallbackGetVar(myVar) { window.external.Callback_GetVar(eval(myVar)); }"
    head.AppendChild(script)
End Sub

Step 7) Add the following VB.Net sub which the Javascript will then look for when invoked:

Public Sub Callback_GetVar(ByVal vVar As String)
    Debug.Print(vVar)
End Sub

Step 8) Finally, to invoke the Javascript callback, add this VB.Net code when a button is pressed, or wherever you like:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    WebBrowser1.Document.InvokeScript("CallbackGetVar", New Object() {"NameOfVarToRetrieve"})
End Sub

Step 9) If it surprises you that this works, you may want to read up on the Javascript "eval" function, used in Step 6, which is what makes this possible. It will take a string and determine whether a variable exists with that name and, if so, returns the value of that variable.

Your code was compiled with Java Version 1.8 while it is being executed with Java Version 1.7 or below.

In your case it seems that two different Java installations are used, the newer to compile and the older to execute your code.

Try recompiling your code with Java 1.7 or upgrade your Java Plugin.

    $('#div2').show();

$('#showdiv3').click(function(){
    $('div[id^=div]').hide();
    $('#div3').show();

$('#showdiv4').click(function(){
    $('div[id^=div]').hide();
    $('#div4').show();

});

You don't need regex for this

>>> s = "Username: How are you today?"

You can use the split method to split the string on the ':' character

>>> s.split(':')
['Username', ' How are you today?']

And slice out element [0] to get the first part of the string

>>> s.split(':')[0]
'Username'

why we have to use globals to get variable name... we can use simply like below.

    $variableName = "ajaxmint";

    echo getVarName('$variableName');

    function getVarName($name) {
        return str_replace('$','',$name);
    }

This is a much easier way to do it within Hive's SQL:

set hive.execution.engine=tez;
set hive.merge.tezfiles=true;
set hive.exec.compress.output=false;

INSERT OVERWRITE DIRECTORY '/tmp/job/'
ROW FORMAT DELIMITED
FIELDS TERMINATED by ','
NULL DEFINED AS ''
STORED AS TEXTFILE
SELECT * from table;

Electricity went down and got this error. Solution was to double click your .ppk (Putty Private Key) and enter your password.

There is no built-in PHP now() function, but you can do it using date().

Example

function now() {
    return date('Y-m-d H:i:s');
}

You can use date_default_timezone_set() if you need to change timezone.

Otherwise you can make use of Carbon - A simple PHP API extension for DateTime.

this part :

"Your new price is: $"(float(price)

asks python to call this string:

"Your new price is: $"

just like you would a function: function( some_args) which will ALWAYS trigger the error:

TypeError: 'str' object is not callable

Consider the following:

1. Variables are pointers to values in memory.
2. Reassigning a variable merely points that pointer at a new value.
3. Reassigning a variable will never affect other variables that were pointing at that same object

So, forget about "pass by reference/value" don't get hung up on "pass by reference/value" because:

1. The terms are only used to describe the behavior of a language, not necessarily the actual underlying implementation. As a result of this abstraction, critical details that are essential for a decent explanation are lost, which inevitably leads to the current situation where a single term doesn't adequately describe the actual behavior and supplementary info has to be provided
2. These concepts were not originally defined with the intent of describing javascript in particular and so I don't feel compelled to use them when they only add to the confusion.

To answer your question: pointers are passed.

// code
var obj = {
    name: 'Fred',
    num: 1
};

// illustration
               'Fred'
              /
             /
(obj) ---- {}
             \
              \
               1

// code
obj.name = 'George';


// illustration
                 'Fred'


(obj) ---- {} ----- 'George'
             \
              \
               1

// code
obj = {};

// illustration
                 'Fred'


(obj)      {} ----- 'George'
  |          \
  |           \
 { }            1

// code
var obj = {
    text: 'Hello world!'
};

/* function parameters get their own pointer to 
 * the arguments that are passed in, just like any other variable */
someFunc(obj);


// illustration
(caller scope)        (someFunc scope)
           \             /
            \           /
             \         /
              \       /
               \     /
                 { }
                  |
                  |
                  |
            'Hello world'

Some final comments:

• It's tempting to think that primitives are enforced by special rules while objects are not, but primitives are simply the end of the pointer chain.
• As a final example, consider why a common attempt to clear an array doesn't work as expected.

var a = [1,2];
var b = a;

a = [];
console.log(b); // [1,2]
// doesn't work because `b` is still pointing at the original array

Yes.

This is so that you can control how the class is instantiated. If you make the constructor private, and then create a visible constructor method that returns instances of the class, you can do things like limit the number of creations (typically, guarantee there is exactly one instance) or recycle instances or other construction-related tasks.

Doing new x() never returns null, but using the factory pattern, you can return null, or even return different subtypes.

You might use it also for a class which has no instance members or properties, just static ones - as in a utility function class.

I wanted to see a benchmark result of functions mentioned in answers including unutbu's.

Also want to point out that numpy doc recommend to use arr.reshape(-1) in case view is preferable. (even though ravel is tad faster in the following result)

TL;DR: np.ravel is the most performant (by very small amount).

Benchmark

Functions:

• np.ravel: returns view, if possible
• np.reshape(-1): returns view, if possible
• np.flatten: returns copy
• np.flat: returns numpy.flatiter. similar to iterable

numpy version: '1.18.0'

Execution times on different ndarray sizes

+-------------+----------+-----------+-----------+-------------+
|  function   |   10x10  |  100x100  | 1000x1000 | 10000x10000 |
+-------------+----------+-----------+-----------+-------------+
| ravel       | 0.002073 |  0.002123 |  0.002153 |    0.002077 |
| reshape(-1) | 0.002612 |  0.002635 |  0.002674 |    0.002701 |
| flatten     | 0.000810 |  0.007467 |  0.587538 |  107.321913 |
| flat        | 0.000337 |  0.000255 |  0.000227 |    0.000216 |
+-------------+----------+-----------+-----------+-------------+

Conclusion

ravel and reshape(-1)'s execution time was consistent and independent from ndarray size. However, ravel is tad faster, but reshape provides flexibility in reshaping size. (maybe that's why numpy doc recommend to use it instead. Or there could be some cases where reshape returns view and ravel doesn't).
If you are dealing with large size ndarray, using flatten can cause a performance issue. Recommend not to use it. Unless you need a copy of the data to do something else.

Used code

import timeit
setup = '''
import numpy as np
nd = np.random.randint(10, size=(10, 10))
'''

timeit.timeit('nd = np.reshape(nd, -1)', setup=setup, number=1000)
timeit.timeit('nd = np.ravel(nd)', setup=setup, number=1000)
timeit.timeit('nd = nd.flatten()', setup=setup, number=1000)
timeit.timeit('nd.flat', setup=setup, number=1000)

put your javascript at the bottom of the page (ie after the element getting defined..)

For macOS/OS X, you can use the subprocess module and call 'cls' from the shell:

import subprocess as sp
sp.call('cls', shell=True)

To prevent '0' from showing on top of the window, replace the 2nd line with:

tmp = sp.call('cls', shell=True)

For Linux, you must replace cls command with clear

tmp = sp.call('clear', shell=True)

I solve it by close safari inspector. Refer to my post. I also found sound sometimes when I run my app for testing, then I open safari with auto inspector on, after this, I do some action in my app then this issue triggered.

Note :- Certainly in python-3x you need to use Range function It works to generate numbers on demand, standard method to use Range function to make a list of consecutive numbers is

x=list(range(10))
#"list"_will_make_all_numbers_generated_by_range_in_a_list
#number_in_range_(10)_is_an_option_you_can_change_as_you_want
print (x)
#Output_is_ [0,1,2,3,4,5,6,7,8,9]

Also if you want to make an function to generate a list of consecutive numbers by using Range function watch this code !

def  consecutive_numbers(n) :
    list=[i for i in range(n)]
    return (list)
print(consecutive_numbers(10))

Good Luck!

To get the current path from within the JSP file you can simply do one of the following:

<%= request.getContextPath() %>
<%= request.getRequestURI() %>
<%= request.getRequestURL() %>

var listItems= "";
var jsonData = jsonObj.d;
    for (var i = 0; i < jsonData.Table.length; i++){
      listItems+= "<option value='" + jsonData.Table[i].stateid + "'>" + jsonData.Table[i].statename + "</option>";
    }
    $("#<%=DLState.ClientID%>").html(listItems);

Example

   <html>
    <head></head>
    <body>
      <select id="DLState">
      </select>
    </body>
    </html>

    /*javascript*/
    var jsonList = {"Table" : [{"stateid" : "2","statename" : "Tamilnadu"},
                {"stateid" : "3","statename" : "Karnataka"},
                {"stateid" : "4","statename" : "Andaman and Nicobar"},
                 {"stateid" : "5","statename" : "Andhra Pradesh"},
                 {"stateid" : "6","statename" : "Arunachal Pradesh"}]}

    $(document).ready(function(){
      var listItems= "";
      for (var i = 0; i < jsonList.Table.length; i++){
        listItems+= "<option value='" + jsonList.Table[i].stateid + "'>" + jsonList.Table[i].statename + "</option>";
      }
      $("#DLState").html(listItems);
    });

Combination of all the answers

Here is what I have arrived at after a read of all the answers presented here as well what some Airgram has done in their SDKs - A utility that I have open sourced on Github:

https://github.com/mankum93/UriUtilsAndroid/tree/master/app/src/main/java/com/androiduriutils

Usage

As simple as calling, UriUtils.getDisplayNameSize(). It provides both the name and size of the content.

Note: Only works with a content:// Uri

Here is a glimpse on the code:

     * @return The Display name and size for content. In case of non-determination, display name
     * would be null and content size would be {@link #CONTENT_SIZE_INVALID}
     */
    @NonNull
    public static DisplayNameAndSize getDisplayNameSize(@NonNull Context context, @NonNull Uri contentUri){

        final String scheme = contentUri.getScheme();
        if(scheme == null || !scheme.equals(ContentResolver.SCHEME_CONTENT)){
            throw new RuntimeException("Only scheme content:// is accepted");
        }

        final DisplayNameAndSize displayNameAndSize = new DisplayNameAndSize();
        displayNameAndSize.size = CONTENT_SIZE_INVALID;

        String[] projection = new String[]{MediaStore.Images.Media.DATA, OpenableColumns.DISPLAY_NAME, OpenableColumns.SIZE};
        Cursor cursor = context.getContentResolver().query(contentUri, projection, null, null, null);
        try {
            if (cursor != null && cursor.moveToFirst()) {

                // Try extracting content size

                int sizeIndex = cursor.getColumnIndex(OpenableColumns.SIZE);
                if (sizeIndex != -1) {
                    displayNameAndSize.size = cursor.getLong(sizeIndex);
                }

                // Try extracting display name
                String name = null;

                // Strategy: The column name is NOT guaranteed to be indexed by DISPLAY_NAME
                // so, we try two methods
                int nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
                if (nameIndex != -1) {
                    name = cursor.getString(nameIndex);
                }

                if (nameIndex == -1 || name == null) {
                    nameIndex = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
                    if (nameIndex != -1) {
                        name = cursor.getString(nameIndex);
                    }
                }
                displayNameAndSize.displayName = name;
            }
        }
        finally {
            if(cursor != null){
                cursor.close();
            }
        }

        // We tried querying the ContentResolver...didn't work out
        // Try extracting the last path segment
        if(displayNameAndSize.displayName == null){
            displayNameAndSize.displayName = contentUri.getLastPathSegment();
        }

        return displayNameAndSize;
    }
}

Now both these methods fail at times when the log file is empty (has no content), yet the file size is not zero (2 bytes).

Actually, I think you will find that the file is NOT empty. Rather I think that you will find that those two characters are a CR and a NL; i.e. the file consists of one line that is empty.

If you want to test if a file is either empty or has a single empty line then a simple, relatively efficient way is:

try (BufferedReader br = new BufferedReader(FileReader(fileName))) {
    String line = br.readLine();
    if (line == null || 
        (line.length() == 0 && br.readLine() == null)) {
        System.out.println("NO ERRORS!");
    } else {
        System.out.println("SOME ERRORS!");
    }
}

Can we do this more efficiently? Possibly. It depends on how often you have to deal with the three different cases:

• a completely empty file
• a file consisting of a single empty line
• a file with a non-empty line, or multiple lines.

You can probably do better by using Files.length() and / or reading just the first two bytes. However, the problems include:

• If you both test the file size AND read the first few bytes then you are making 2 syscalls.
• The actual line termination sequence could be CR, NL or CR NL, depending on the platform. (I know you say this is for Windows, but what happens if you need to port your application? Or if someone sends you a non-Windows file?)
• It would be nice to avoid setting up stream / reader stack, but the file's character encoding could map CR and NL to something other than the bytes 0x0d and 0x0a. (For example ... UTF-16)
• Then there's the annoying habit of some Windows utilities have putting BOM markers into UTF-8 encoded files. (This would even mess up the simple version above!)

All of this means that the most efficient possible solution is going to be rather complicated.

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

Here you go:

>>> data = """a,b,c
d,e,f
g,h,i
j,k,l"""
>>> data.split()  # split automatically splits through \n and space
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
>>> 

Same applies for guard statements. The same error message lead me to this post and answer (thanks @nhgrif).

The code: Print the last name of the person only if the middle name is less than four characters.

func greetByMiddleName(name: (first: String, middle: String?, last: String?)) {
    guard let Name = name.last where name.middle?.characters.count < 4 else {
        print("Hi there)")
        return
    }
    print("Hey \(Name)!")
}

Until I declared last as an optional parameter I was seeing the same error.

A better regex to use to check if a string is HTML is:

/^/

For example:

/^/.test('') // true
/^/.test('foo bar baz') //true
/^/.test('<p>fizz buzz</p>') //true

In fact, it's so good, that it'll return true for every string passed to it, which is because every string is HTML. Seriously, even if it's poorly formatted or invalid, it's still HTML.

If what you're looking for is the presence of HTML elements, rather than simply any text content, you could use something along the lines of:

/<\/?[a-z][\s\S]*>/i.test()

It won't help you parse the HTML in any way, but it will certainly flag the string as containing HTML elements.

It's a ProgressDialog, with setIndeterminate(true).

From http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog

ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", 
                    "Loading. Please wait...", true);

An indeterminate progress bar doesn't actually show a bar, it shows a spinning activity circle thing. I'm sure you know what I mean :)

Here is a way to call controller's function from outside of it:

angular.element(document.getElementById('yourControllerElementID')).scope().get();

where get() is a function from your controller.

You can switch

document.getElementById('yourControllerElementID')` 

to

$('#yourControllerElementID')

If you are using jQuery.

Also, if your function means changing anything on your View, you should call

angular.element(document.getElementById('yourControllerElementID')).scope().$apply();

to apply the changes.

One more thing, you should note is that scopes are initialized after the page is loaded, so calling methods from outside of scope should always be done after the page is loaded. Else you will not get to the scope at all.

UPDATE:

With the latest versions of angular, you should use

angular.element(document.getElementById('yourControllerElementID')).injector().??get('$rootScope')

And yes, this is, in fact, a bad practice, but sometimes you just need things done quick and dirty.

This is the self-invoking anonymous function. It is executed while it is defined. Which means this function is defined and invokes itself immediate after the definition.

And the explanation of the syntax is: The function within the first () parenthesis is the function which has no name and by the next (); parenthesis you can understand that it is called at the time it is defined. And you can pass any argument in this second () parenthesis which will be grabbed in the function which is in the first parenthesis. See this example:

(function(obj){
    // Do something with this obj
})(object);

Here the 'object' you are passing will be accessible within the function by 'obj', as you are grabbing it in the function signature.

Try giving your table an ID and then using !important to set border to none in CSS. If JavaScript is tampering with your table then that should get around it.

<table id="mytable"
...

table#mytable,
table#mytable td
{
    border: none !important;
}

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...

From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.

Just to close this

foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
    //textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

Changes to this

foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
    //textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
    textBox3.Text += string.Format("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

This normally works for me:

if ($("#r1").is(":checked")) {}

date -j -f "%Y-%m-%d" "2010-10-02" "+%s"

If you're using Bash, you can also do the following if, let's say, you want to remove the directory /home/wrong/dir/ from your PATH variable:

PATH=`echo $PATH | sed -e 's/:\/home\/wrong\/dir\/$//'`

System.out.println and Log.d both go to LogCat, not the Console.

Why don't you put your results into a vector? That way you don't have to know the size before hand.

"%.2f" does not return a clean float. It returns a string representing this float with two decimals.

my_list = [0.30000000000000004, 0.5, 0.20000000000000001]
my_formatted_list = [ '%.2f' % elem for elem in my_list ]

returns:

['0.30', '0.50', '0.20']

Also, don't call your variable list. This is a reserved word for list creation. Use some other name, for example my_list.

If you want to obtain [0.30, 0.5, 0.20] (or at least the floats that are the closest possible), you can try this:

my_rounded_list = [ round(elem, 2) for elem in my_list ]

returns:

[0.29999999999999999, 0.5, 0.20000000000000001]

This works for mysql version 5.5.32

ALTER TABLE  `tablename` ADD UNIQUE (`column1` ,`column2`);

You cannot get stdout to print unbuffered to a pipe (unless you can rewrite the program that prints to stdout), so here is my solution:

Redirect stdout to sterr, which is not buffered. '<cmd> 1>&2' should do it. Open the process as follows: myproc = subprocess.Popen('<cmd> 1>&2', stderr=subprocess.PIPE)
You cannot distinguish from stdout or stderr, but you get all output immediately.

Hope this helps anyone tackling this problem.

There is no work-around for this aside from ditching the select element.

Below example will help to find the specific folder in the current directory. This example only search current direct and it'll search sub directory available in the current directory

then 
   echo "TRUE"
else

Trivial to use and you have full control on the layout since you can use razor views with data from your Model and ViewBag container.

I developed a SaaS version on Azure. It makes it even easier to use it from WebApi or any .Net app, service, Azure website, Azure webjob, whatever runs .Net.

Here is a literal pure Python translation of the Welford's algorithm implementation from http://www.johndcook.com/standard_deviation.html:

https://github.com/liyanage/python-modules/blob/master/running_stats.py

import math

class RunningStats:

    def __init__(self):
        self.n = 0
        self.old_m = 0
        self.new_m = 0
        self.old_s = 0
        self.new_s = 0

    def clear(self):
        self.n = 0

    def push(self, x):
        self.n += 1

        if self.n == 1:
            self.old_m = self.new_m = x
            self.old_s = 0
        else:
            self.new_m = self.old_m + (x - self.old_m) / self.n
            self.new_s = self.old_s + (x - self.old_m) * (x - self.new_m)

            self.old_m = self.new_m
            self.old_s = self.new_s

    def mean(self):
        return self.new_m if self.n else 0.0

    def variance(self):
        return self.new_s / (self.n - 1) if self.n > 1 else 0.0

    def standard_deviation(self):
        return math.sqrt(self.variance())

Usage:

rs = RunningStats()
rs.push(17.0)
rs.push(19.0)
rs.push(24.0)

mean = rs.mean()
variance = rs.variance()
stdev = rs.standard_deviation()

print(f'Mean: {mean}, Variance: {variance}, Std. Dev.: {stdev}')

allow_url_fopen is generally set to On. If it is not On, then you can try two things.

1. Create an .htaccess file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.

   php_value allow_url_fopen On
   

2. Create a php.ini file (for update server php5.ini) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:

   allow_url_fopen = On;
   

I have personally tested the above solutions; they worked for me.

A native javascript implementation of WunderBart's answer.

function onClick() {

  // create invisible dummy input to receive the focus first
  const fakeInput = document.createElement('input')
  fakeInput.setAttribute('type', 'text')
  fakeInput.style.position = 'absolute'
  fakeInput.style.opacity = 0
  fakeInput.style.height = 0
  fakeInput.style.fontSize = '16px' // disable auto zoom

  // you may need to append to another element depending on the browser's auto 
  // zoom/scroll behavior
  document.body.prepend(fakeInput)

  // focus so that subsequent async focus will work
  fakeInput.focus()

  setTimeout(() => {

    // now we can focus on the target input
    targetInput.focus()

    // cleanup
    fakeInput.remove()
    
  }, 1000)

}

I know that I have this problem over and over when I deploy my application on a new server because I'm using this driver to connect to a Excel file. So here it is what I'm doing lately.

There's a Windows Server 2008 R2, I install the Access drivers for a x64 bit machine and I get rid of this message, which makes me very happy just to bump into another.

This one here below works splendidly on my dev machine but on server gives me an error even after installing the latest ODBC drivers, which I think this is the problem, but this is how I solved it.

private const string OledbProviderString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\OlsonWindows.xls;Extended Properties=\"Excel 8.0;HDR=YES\"";

I replace with the new provider like this below:

private const string OledbProviderString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xlsx;Extended Properties='Excel 12.0;HDR=YES;';";

But as I do this, there's one thing you should notice. Using the .xlsx file extension and Excel version is 12.0.

After I get into this error message Error: "Could Not Find Installable ISAM", I decide to change the things a little bit like below:

private const string OledbProviderString =      @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xls;Extended Properties='Excel 8.0;HDR=YES;';"; 

and yes, I'm done with that nasty thing, but here I got another message The Microsoft Access database engine cannot open or write to the file 'time_zone'. It is already opened exclusively by another user, or you need permission to view and write its data. which tells me I'm not far away from solving it.

Maybe there's another process that opened the file meanwhile and all that I have to do is a restart and all will take start smoothly running as expected.

In my case it is similar to @Michael Easter: I got a problem in a job due to lack of disk space. I cleared some space, restarted Jenkins but still the problem persisted.

The solution was to go to Jenkins -> Manage Jenkins -> Manage Nodes and just Click on the button to update the status.

I was using spring boot 1.5.10 and tries to exclude logback, the given solution above did not work well, I use configurations instead

configurations.all {
    exclude group: "org.springframework.boot", module:"spring-boot-starter-logging"
}

i received this message for an application on iis 7.5 with a classic app pool assigned to .net 2.0. i needed to go to Handler Mappings and add two script maps, both were the same with except for the name. one name was svc-ISAPI-2.0-64, the other was svc-ISAPI-2.0. The request path was .svc. And the Executable was %SystemRoot%\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll. i restarted iis and all was happy

I had the same issue. I wanted to send data via POST. I used the following code:

    URL url = new URL("http://example.com/getval.php");
    Map<String,Object> params = new LinkedHashMap<>();
    params.put("param1", param1);
    params.put("param2", param2);

    StringBuilder postData = new StringBuilder();
    for (Map.Entry<String,Object> param : params.entrySet()) {
        if (postData.length() != 0) postData.append('&');
        postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
        postData.append('=');
        postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
    }
    String urlParameters = postData.toString();
    URLConnection conn = url.openConnection();

    conn.setDoOutput(true);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(urlParameters);
    writer.flush();

    String result = "";
    String line;
    BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));

    while ((line = reader.readLine()) != null) {
        result += line;
    }
    writer.close();
    reader.close()
    System.out.println(result);

I used Jsoup for parse:

    Document doc = Jsoup.parseBodyFragment(value);
    Iterator<Element> opts = doc.select("option").iterator();
    for (;opts.hasNext();) {
        Element item = opts.next();
        if (item.hasAttr("value")) {
            System.out.println(item.attr("value"));
        }
    }

CSS

:active denotes the interaction state (so for a button will be applied during press), :focus may be a better choice here. However, the styling will be lost once another element gains focus.

The final potential alternative using CSS would be to use :target, assuming the items being clicked are setting routes (e.g. anchors) within the page- however this can be interrupted if you are using routing (e.g. Angular), however this doesnt seem the case here.

.active:active {_x000D_
  color: red;_x000D_
}_x000D_
.focus:focus {_x000D_
  color: red;_x000D_
}_x000D_
:target {_x000D_
  color: red;_x000D_
}

<button class='active'>Active</button>_x000D_
<button class='focus'>Focus</button>_x000D_
<a href='#target1' id='target1' class='target'>Target 1</a>_x000D_
<a href='#target2' id='target2' class='target'>Target 2</a>_x000D_
<a href='#target3' id='target3' class='target'>Target 3</a>

Javascript / jQuery

As such, there is no way in CSS to absolutely toggle a styled state- if none of the above work for you, you will either need to combine with a change in your HTML (e.g. based on a checkbox) or programatically apply/remove a class using e.g. jQuery

$('button').on('click', function(){_x000D_
    $('button').removeClass('selected');_x000D_
    $(this).addClass('selected');_x000D_
});

button.selected{_x000D_
  color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<button>Item</button><button>Item</button><button>Item</button>_x000D_
  

AMG - Sorry all, was having a blond moment. The field "Additional" was added to the database after I had initially designed the database.

I updated all my code to use this new field, however I forgot to update the actual datareader code that was making the call to select the database fields, therefore it wasn't calling "Additional"

A very simple and elegant solution to this is provided by W3C. Simply use the margin:0 auto declaration as follows:

.top_image img { margin:0 auto; }

More information and examples from W3C.

If you are using springboot then jackson is added by default,

So the version of jackson you are adding manualy is probably conflicting with the one spring boot adds,

Try to delete the jackson dependencies from your pom,

If you need to override the version spring boots add, then you need to exclude it first and then add your own

I have a char array:

char* name = "hello";

No, you have a character pointer to a string literal. In many usages you could add the const modifier, depending on whether you are more interested in what name points to, or the string value, "hello". You shouldn't attempt to modify the literal ("hello"), because bad things can happen.

The major thing to convey is that C does not have a proper (or first-class) string type. "Strings" are typically arrays of chars (characters) with a terminating null ('\0' or decimal 0) character to signify end of a string, or pointers to arrays of characters.

I would suggest reading Character Arrays, section 1.9 in The C Programming Language (page 28 second edition). I strongly recommend reading this small book ( <300 pages), in order to learn C.

Further to your question, sections 6 - Arrays and Pointers and section 8 - Characters and Strings of the C FAQ might help. Question 6.5, and 8.4 might be good places to start.

I hope that helps you to understand why your excerpt doesn't work. Others have outlined what changes are needed to make it work. Basically you need an char array (an array of characters) big enough to store the entire string with a terminating (ending) '\0' character. Then you can use the standard C library function strcpy (or better yet strncpy) to copy the "Hello" into it, and then you want to concatenate using the standard C library strcat (or better yet strncat) function. You will want to include the string.h header file to declare the functions declarations.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main( int argc, char *argv[] )
{
    char filename[128];
    char* name = "hello";
    char* extension = ".txt";

    if (sizeof(filename) < strlen(name) + 1 ) { /* +1 is for null character */
        fprintf(stderr, "Name '%s' is too long\n", name);
        return EXIT_FAILURE;
    }
    strncpy(filename, name, sizeof(filename));

    if (sizeof(filename) < (strlen(filename) + strlen(extension) + 1) ) {
        fprintf(stderr, "Final size of filename is too long!\n");
        return EXIT_FAILURE;
    }
    strncat(filename, extension, (sizeof(filename) - strlen(filename)) );
    printf("Filename is %s\n", filename);

    return EXIT_SUCCESS;
}

You could use a regex, yes, but a simple string.Replace() will probably suffice.

 myString = myString.Replace("\r\n", string.Empty);

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

In my case I needed a lower JRE, so I had to tell IntelliJ to use a different one in "Platform Settings"

• Platform Settings > SDKs ( ⌘+; )
• Click the + button to add a new SDK (or rename and load an existing one)
• Choose the /Contents/Home directory from the appropriate SDK
  (i.e. /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home)

This answer is for MacOs Catalina user or zsh users as your Mac now uses zsh as the default login shell and interactive shell.

If you follow along with the docs of React Native Setting up the development environment guide. Then do the following.

Firstly check if local.properties file exists or not. If the file does not exist then create and add the following line.

sdk.dir=/Users/<youcomputername>/Library/Android/sdk

After doing the above changes now do the following.

1. Open ~/.zshrc using a code-editor. In my case I use vim

vim ~/.zshrc

2. Add the following line for the path.

export ANDROID_HOME="/Users/<yourcomputername>/Library/Android/sdk"
export PATH=$ANDROID_HOME/emulator:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/tools/bin:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH

Make sure to add the above line correctly else it will give you a weird error.

4. Save the changes and close the editor.

5. Finally, now compile your changes

source ~/.zshrc

I get this working in my case. I hope this helps you.

To set your ImageView equal to half the screen, you need to add the following to your XML for the ImageView:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:scaleType="fitXY"
    android:adjustViewBounds="true"/>

To then set the height equal to this width, you need to do it in code. In the getView method of your GridView adapter, set the ImageView height equal to its measured width:

mImageView.getLayoutParams().height = mImageView.getMeasuredWidth();

There is no public API for this yet. see Sun Bug 4244896, Sun Bug 4250622

As a workaround:

Runtime.exec(...)

returns an Object of type

java.lang.Process

The Process class is abstract, and what you get back is some subclass of Process which is designed for your operating system. For example on Macs, it returns java.lang.UnixProcess which has a private field called pid. Using Reflection you can easily get the value of this field. This is admittedly a hack, but it might help. What do you need the PID for anyway?

Try below code,

Intent intent = new Intent(ManageProfileActivity.this, LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                Intent.FLAG_ACTIVITY_CLEAR_TASK| 
                Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Override the default input onChange behavior (call the function only when control loss focus and value was change)

NOTE: ngChange is not similar to the classic onChange event it firing the event while the value is changing This directive stores the value of the element when it gets the focus
On blurs it checks whether the new value has changed and if so it fires the event

@param {String} - function name to be invoke when the "onChange" should be fired

@example < input my-on-change="myFunc" ng-model="model">

angular.module('app', []).directive('myOnChange', function () { 
    return {
        restrict: 'A',
        require: 'ngModel',
        scope: {
            myOnChange: '='
        },
        link: function (scope, elm, attr) {
            if (attr.type === 'radio' || attr.type === 'checkbox') {
                return;
            }
            // store value when get focus
            elm.bind('focus', function () {
                scope.value = elm.val();

            });

            // execute the event when loose focus and value was change
            elm.bind('blur', function () {
                var currentValue = elm.val();
                if (scope.value !== currentValue) {
                    if (scope.myOnChange) {
                        scope.myOnChange();
                    }
                }
            });
        }
    };
});

1. Java provides lot of things with proper implementation lot of complexity can be avoided. This returns ms_MY.

   String key = "ms-MY";
   Locale locale = new Locale.Builder().setLanguageTag(key).build();
   

2. Apache Commons has LocaleUtils to help parse a string representation. This will return en_US

   String str = "en-US";
   Locale locale =  LocaleUtils.toLocale(str);
   System.out.println(locale.toString());
   

3. You can also use locale constructors.

   // Construct a locale from a language code.(eg: en)
   new Locale(String language)
   // Construct a locale from language and country.(eg: en and US)
   new Locale(String language, String country)
   // Construct a locale from language, country and variant.
   new Locale(String language, String country, String variant)
   

Please check this LocaleUtils and this Locale to explore more methods.

Okay, I have refined my regular expression based on the solution you came up with (which erroneously matches strings that start with 'test').

^((?!foo).)*$

This regular expression will match only strings that do not contain foo. The first lookahead will deny strings beginning with 'foo', and the second will make sure that foo isn't found elsewhere in the string.

To solve a similar problem, I'm using groupby:

print(f"Distinct entries: {len(df.groupby(['col1', 'col2']))}")

Whether that's appropriate will depend on what you want to do with the result, though (in my case, I just wanted the equivalent of COUNT DISTINCT as shown).

Adding libraries with resources To add a Support Library with resources (such as v7 appcompat for action bar) to your application project:

Using Eclipse

Create a library project based on the support library code:

• Make sure you have downloaded the Android Support Library using the SDK Manager.

• Create a library project and ensure the required JAR files are included in the project's build path:

• Select File > Import.

• Select Existing Android Code Into Workspace and click Next.

• Browse to the SDK installation directory and then to the Support Library folder. For example, if you are adding the appcompat project, browse to /extras/android/support/v7/appcompat/.

• Click Finish to import the project. For the v7 appcompat project, you should now see a new project titled android-support-v7-appcompat.

• In the new library project, expand the libs/ folder, right-click each .jar file and select Build

• Path > Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path.

• Right-click the library project folder and select Build Path > Configure Build Path.

• In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.

• Uncheck Android Dependencies.

• Click OK to complete the changes.

• You now have a library project for your selected Support Library that you can use with one or more application projects.

• Add the library to your application project:

• In the Project Explorer, right-click your project and select Properties.

• In the category panel on the left side of the dialog, select Android.

• In the Library pane, click the Add button.

• Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.

• In the properties window, click OK.

For me the UnicodeWriter class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row() interface.

For example:

csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

works, while:

csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

will throw AttributeError: 'int' object has no attribute 'encode'.

As UnicodeWriter obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:

def to_utf8(lst):
    return [unicode(elem).encode('utf-8') for elem in lst]

...
csv_writer.writerow(to_utf8(row))

Or we can even monkey-patch csv_writer to add a write_utf8_row function - the exercise is left to the reader.

This is because your $JAVA_HOME is not set. If you are using a Mac:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home" in .bash_profile

The canvas element provides a toDataURL method which returns a data: URL that includes the base64-encoded image data in a given format. For example:

var jpegUrl = canvas.toDataURL("image/jpeg");
var pngUrl = canvas.toDataURL(); // PNG is the default

Although the return value is not just the base64 encoded binary data, it's a simple matter to trim off the scheme and the file type to get just the data you want.

The toDataURL method will fail if the browser thinks you've drawn to the canvas any data that was loaded from a different origin, so this approach will only work if your image files are loaded from the same server as the HTML page whose script is performing this operation.

For more information see the MDN docs on the canvas API, which includes details on toDataURL, and the Wikipedia article on the data: URI scheme, which includes details on the format of the URI you'll receive from this call.

I personally prefer using char(1) with values 'Y' and 'N' for databases that don't have a native type for boolean. Letters are more user frendly than numbers which assume that those reading it will now that 1 corresponds to true and 0 corresponds to false.

'Y' and 'N' also maps nicely when using (N)Hibernate.

By default, cin reads from the input discarding any spaces. So, all you have to do is to use a do while loop to read the input more than one time:

do {
   cout<<"Enter a number, or numbers separated by a space, between 1 and 1000."<<endl;
   cin >> num;

   // reset your variables

   // your function stuff (calculations)
}
while (true); // or some condition

Probably the simplest way is to use the InputBox method of the Microsoft.VisualBasic.Interaction class:

[void][Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')

$title = 'Demographics'
$msg   = 'Enter your demographics:'

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title)

The simplest solution is to add this CSS to the children:

.your-child {
    pointer-events: none;
}

For me it was because I hadn't set an active class on any of the slides.

keytool is a tool to manage (public/private) security keys and certificates and store them in a Java KeyStore file (stored_file_name.jks).
It is provided with any standard JDK/JRE distributions.
You can find it under the following folder %JAVA_HOME%\bin.

You can also do it by creating a string column with the year and month as follows:

df['date'] = df.index
df['year-month'] = df['date'].apply(lambda x: str(x.year) + ' ' + str(x.month))
grouped = df.groupby('year-month')

However this doesn't preserve the order when you loop over the groups, e.g.

for name, group in grouped:
    print(name)

Will give:

2007 11
2007 12
2008 1
2008 10
2008 11
2008 12

So then, if you want to preserve the order, you must do as suggested by @Q-man above:

grouped = df.groupby([df.index.year, df.index.month])

This will preserve the order in the above loop:

(2007, 11)
(2007, 12)
(2008, 1)
(2008, 2)
(2008, 3)
(2008, 4)
(2008, 5)
(2008, 6)
(2008, 7)
(2008, 8)
(2008, 9)
(2008, 10)

Several years late to the party but I want to both sort on 2 criteria and use reverse=True. In case someone else wants to know how, you can wrap your criteria (functions) in parenthesis:

s = sorted(my_list, key=lambda i: ( criteria_1(i), criteria_2(i) ), reverse=True)

I realize this is a very old question, but I don't see one crucial aspect mentioned in any of the answers: inlining into query plan.

Functions can be...

1. Scalar:

   CREATE FUNCTION ... RETURNS scalar_type AS BEGIN ... END

2. Multi-statement table-valued:

   CREATE FUNCTION ... RETURNS @r TABLE(...) AS BEGIN ... END

3. Inline table-valued:

   CREATE FUNCTION ... RETURNS TABLE AS RETURN SELECT ...

The third kind (inline table-valued) are treated by the query optimizer essentially as (parametrized) views, which means that referencing the function from your query is similar to copy-pasting the function's SQL body (without actually copy-pasting), leading to the following benefits:

• The query planner can optimize the inline function's execution just as it would any other sub-query (e.g. eliminate unused columns, push predicates down, pick different JOIN strategies etc.).
• Combining several inline function doesn't require materializing the result from the first one before feeding it to the next.

The above can lead to potentially significant performance savings, especially when combining multiple levels of functions.

NOTE: Looks like SQL Server 2019 will introduce some form of scalar function inlining as well.

For users that want better formatting,

import time
start_time = time.time()
# your script
elapsed_time = time.time() - start_time
time.strftime("%H:%M:%S", time.gmtime(elapsed_time))

will print out, for 2 seconds:

'00:00:02'

and for 7 minutes one second:

'00:07:01'

note that the minimum time unit with gmtime is seconds. If you need microseconds consider the following:

import datetime
start = datetime.datetime.now()
# some code
end = datetime.datetime.now()
elapsed = end - start
print(elapsed)
# or
print(elapsed.seconds,":",elapsed.microseconds) 

strftime documentation

There's a few ways to do this depending on how you want to hold the value.

You can use basic string formatting, e.g

'Your Meal Price is %.2f' %  mealPrice

You can modify the 2 to whatever precision you need.

However, since you're dealing with money you should look into the decimal module which has a cool method named quantize which is exactly for working with monetary applications. You can use it like so:

from decimal import Decimal, ROUND_DOWN
mealPrice = Decimal(str(mealPrice)).quantize(Decimal('.01'), rounding=ROUND_DOWN)

Note that the rounding attribute is purely optional as well.

To make sure the event always only fires once, you can use Jquery .one() . JQuery one ensures that your event handler only called once. Additionally, you can subscribe your event handler with one to allow further clicks when you have finished the processing of the current click operation.

<div id="testDiv">
  <button class="testClass">Test Button</button>
</div>

…

var subscribeClickEvent = function() {$("#testDiv").one("click", ".testClass", clickHandler);};

function clickHandler() {
  //... perform the tasks  
  alert("you clicked the button");
  //... subscribe the click handler again when the processing of current click operation is complete  
  subscribeClickEvent();
}

subscribeClickEvent();

If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:

inputElement.onchange = function(event) {
   var fileList = inputElement.files;
   //TODO do something with fileList.  
}

See this MDN article for more info on the FileList type.

Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files property in non-File API browsers.

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

In case you want to be fully bomb prove, this is what I would advice:

@('Apples', 'Apples ', 'APPLES', 'Banana') | 
    Sort-Object -Property @{Expression={$_.Trim()}} -Unique

Output:

Apples
Banana

This uses the Property parameter to first Trim() the strings, so extra spaces are removed and then selects only the -Unique values.

I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):

aptitude install debian-archive-keyring

In case it is some other keyring you need, check out

apt-cache search keyring | grep debian

My squeeze system shows all these:

debian-archive-keyring       - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring   - GnuPG archive keys of the Debian Edu archive
debian-keyring               - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring     - GnuPG archive keys for the emdebian repository

Use this to experiment with mailto form elements and link encoding.

You can enter subject, body (i.e. content), etc. into the form, hit the button and see the mailto html link that you can paste into your page.

You can even specify elements that are rarely known and used: cc, bcc, from emails.

I think the problem is, that you're trying to set width to an inline element which I'm not sure is possible. In general Li is block and this would work.

I know this is really late, but posting it anyway just in case it helps others. Here is a function I came up with that seems to do a good job of counting differences in months between two dates. It is admittedly a great deal raunchier than Mr.Crowder's, but provides more accurate results by stepping through the date object. It is in AS3 but you should just be able to drop the strong typing and you'll have JS. Feel free to make it nicer looking anyone out there!

    function countMonths ( startDate:Date, endDate:Date ):int
    {
        var stepDate:Date = new Date;
        stepDate.time = startDate.time;
        var monthCount:int;

        while( stepDate.time <= endDate.time ) { 
            stepDate.month += 1;
            monthCount += 1;
        }           

        if ( stepDate != endDate ) { 
            monthCount -= 1;
        }

        return monthCount;
    }

You can use backslash to quote "funny" characters in your jQuery selectors:

$('#input\\[23\\]')

For attribute values, you can use quotes:

$('input[name="weirdName[23]"]')

Now, I'm a little confused by your example; what exactly does your HTML look like? Where does the string "inputName" show up, in particular?

edit fixed bogosity; thanks @Dancrumb

When I had this problem, I had included the mail-api.jar in my maven pom file. That's the API specification only. The fix is to replace this:

<!-- DO NOT USE - it's just the API, not an implementation -->
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>

with the reference implementation of that api:

<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>

I know it has sun in the package name, but that's the latest version. I learned this from https://stackoverflow.com/a/28935760/1128668

The three most used and well supported jQuery grid plugins today are SlickGrid, jqGrid and DataTables. See http://wiki.jqueryui.com/Grid-OtherGrids for more info.

Update: You can find Material Design icons here.

It's important to point out that install and install:install are different things, install is a phase, in which maven do more than just install current project modules artifacs to local repository, it check remote repository first. On the other hand, install:install is a goal, it just build your current project and install all it's artifacts to local repository (e.g. into the .m2 directory).

Use the same function (cor) on a data frame, e.g.:

> cor(VADeaths)
             Rural Male Rural Female Urban Male Urban Female
Rural Male    1.0000000    0.9979869  0.9841907    0.9934646
Rural Female  0.9979869    1.0000000  0.9739053    0.9867310
Urban Male    0.9841907    0.9739053  1.0000000    0.9918262
Urban Female  0.9934646    0.9867310  0.9918262    1.0000000

Or, on a data frame also holding discrete variables, (also sometimes referred to as factors), try something like the following:

Here's more versions of the same that produce slightly different results:

glob.iglob()

import glob
for f in glob.iglob("/mydir/*/*.txt"): # generator, search immediate subdirectories 
    print f

glob.glob1()

print glob.glob1("/mydir", "*.tx?")  # literal_directory, basename_pattern

fnmatch.filter()

import fnmatch, os
print fnmatch.filter(os.listdir("/mydir"), "*.tx?") # include dot-files

Technically, you can use StackTrace, but this is very slow and will not give you the answers you expect a lot of the time. This is because during release builds optimizations can occur that will remove certain method calls. Hence you can't be sure in release whether stacktrace is "correct" or not.

Really, there isn't any foolproof or fast way of doing this in C#. You should really be asking yourself why you need this and how you can architect your application, so you can do what you want without knowing which method called it.

I had this same problem and after trying a variety of things like changing the path variables I went to java.com on a whim and downloaded java, installed, and lo and behold the sdk manager worked after that.

Calculator SOAP service test from SoapUI, Online SoapClient Calculator

Generate the SoapMessage object form the input SoapEnvelopeXML and SoapDataXml.

SoapEnvelopeXML

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <tem:Add xmlns:tem="http://tempuri.org/">
         <tem:intA>3</tem:intA>
         <tem:intB>4</tem:intB>
      </tem:Add>
   </soapenv:Body>
</soapenv:Envelope>

use the following code to get SoapMessage Object.

MessageFactory messageFactory = MessageFactory.newInstance();
    MimeHeaders headers = new MimeHeaders();
    ByteArrayInputStream xmlByteStream = new ByteArrayInputStream(SoapEnvelopeXML.getBytes());
SOAPMessage soapMsg = messageFactory.createMessage(headers, xmlByteStream);

SoapDataXml

<tem:Add xmlns:tem="http://tempuri.org/">
    <tem:intA>3</tem:intA>
    <tem:intB>4</tem:intB>
</tem:Add>

use below code to get SoapMessage Object.

public static SOAPMessage getSOAPMessagefromDataXML(String saopBodyXML) throws Exception {
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    dbFactory.setNamespaceAware(true);
    dbFactory.setIgnoringComments(true);
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    InputSource ips = new org.xml.sax.InputSource(new StringReader(saopBodyXML));
    Document docBody = dBuilder.parse(ips);
    System.out.println("Data Document: "+docBody.getDocumentElement());
    
    MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
    SOAPMessage soapMsg = messageFactory.createMessage();
    
    SOAPBody soapBody = soapMsg.getSOAPPart().getEnvelope().getBody();
    soapBody.addDocument(docBody);
    
    return soapMsg;
}

By getting the SoapMessage Object. It is clear that the Soap XML is valid. Then prepare to hit the service to get response. It can be done in many ways.

1. Using Client Code Generated form WSDL.

java.net.URL endpointURL = new java.net.URL(endPointUrl);
javax.xml.rpc.Service service = new org.apache.axis.client.Service();
((org.apache.axis.client.Service) service).setTypeMappingVersion("1.2");
CalculatorSoap12Stub obj_axis = new CalculatorSoap12Stub(endpointURL, service);
int add = obj_axis.add(10, 20);
System.out.println("Response: "+ add);

2. Using javax.xml.soap.SOAPConnection.

public static void getSOAPConnection(SOAPMessage soapMsg) throws Exception {
    System.out.println("===== SOAPConnection =====");
    MimeHeaders headers = soapMsg.getMimeHeaders(); // new MimeHeaders();
    headers.addHeader("SoapBinding",   serverDetails.get("SoapBinding") );
    headers.addHeader("MethodName",    serverDetails.get("MethodName") );
    headers.addHeader("SOAPAction",    serverDetails.get("SOAPAction") );
    headers.addHeader("Content-Type",  serverDetails.get("Content-Type"));
    headers.addHeader("Accept-Encoding", serverDetails.get("Accept-Encoding"));
    if (soapMsg.saveRequired()) {
        soapMsg.saveChanges();
    }
    
    SOAPConnectionFactory newInstance = SOAPConnectionFactory.newInstance();
    javax.xml.soap.SOAPConnection connection = newInstance.createConnection();
    SOAPMessage soapMsgResponse = connection.call(soapMsg, getURL( serverDetails.get("SoapServerURI"), 5*1000 ));
    
    getSOAPXMLasString(soapMsgResponse);
}

3. Form HTTP Connection Classes org.apache.commons.httpclient.

public static void getHttpConnection(SOAPMessage soapMsg) throws SOAPException, IOException {
    System.out.println("===== HttpClient =====");
    HttpClient httpClient = new HttpClient();
    HttpConnectionManagerParams params = httpClient.getHttpConnectionManager().getParams();
    params.setConnectionTimeout(3 * 1000); // Connection timed out
    params.setSoTimeout(3 * 1000);         // Request timed out
    params.setParameter("http.useragent", "Web Service Test Client");

    PostMethod methodPost = new PostMethod( serverDetails.get("SoapServerURI") );
    methodPost.setRequestBody( getSOAPXMLasString(soapMsg) );
    methodPost.setRequestHeader("Content-Type", serverDetails.get("Content-Type") );
    methodPost.setRequestHeader("SoapBinding",  serverDetails.get("SoapBinding") );
    methodPost.setRequestHeader("MethodName",   serverDetails.get("MethodName") );
    methodPost.setRequestHeader("SOAPAction",   serverDetails.get("SOAPAction") );

    methodPost.setRequestHeader("Accept-Encoding", serverDetails.get("Accept-Encoding"));

    try {
        int returnCode = httpClient.executeMethod(methodPost);
        if (returnCode == HttpStatus.SC_NOT_IMPLEMENTED) {
            System.out.println("The Post method is not implemented by this URI");
            methodPost.getResponseBodyAsString();
        } else {
            BufferedReader br = new BufferedReader(new InputStreamReader(methodPost.getResponseBodyAsStream()));
            String readLine;
            while (((readLine = br.readLine()) != null)) {
                System.out.println(readLine);
            }
            br.close();
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        methodPost.releaseConnection();
    }
}

public static void accessResource_AppachePOST(SOAPMessage soapMsg) throws Exception {
    System.out.println("===== HttpClientBuilder =====");
    CloseableHttpClient httpClient = HttpClientBuilder.create().build();
    URIBuilder builder = new URIBuilder( serverDetails.get("SoapServerURI") );

A different base R alternative would be to first order by id and stopSequence, split them based on id and for every id we select only the first and last index and subset the dataframe using those indices.

df[sapply(with(df, split(order(id, stopSequence), id)), function(x) 
                   c(x[1], x[length(x)])), ]


#  id stopId stopSequence
#1  1      a            1
#3  1      c            3
#5  2      b            1
#6  2      c            4
#8  3      b            1
#7  3      a            3

Or similar using by

df[unlist(with(df, by(order(id, stopSequence), id, function(x) 
                   c(x[1], x[length(x)])))), ]

Packages and stored procedures in Oracle execute by default using the rights of the package/procedure OWNER, not the currently logged on user.

So if you call a package that creates a user for example, its the package owner, not the calling user that needs create user privilege. The caller just needs to have execute permission on the package.

If you would prefer that the package should be run using the calling user's permissions, then when creating the package you need to specify AUTHID CURRENT_USER

Oracle documentation "Invoker Rights vs Definer Rights" has more information http://docs.oracle.com/cd/A97630_01/appdev.920/a96624/08_subs.htm#18575

Hope this helps.

Use it for anonymous types - that's what it's there for. Anything else is a use too far. Like many people who grew up on C, I'm used to looking at the left of the declaration for the type. I don't look at the right side unless I have to. Using var for any old declaration makes me do that all the time, which I personally find uncomfortable.

Those saying 'it doesn't matter, use what you're happy with' are not seeing the whole picture. Everyone will pick up other people's code at one point or another and have to deal with whatever decisions they made at the time they wrote it. It's bad enough having to deal with radically different naming conventions, or - the classic gripe - bracing styles, without adding the whole 'var or not' thing into the mix. The worst case will be where one programmer didn't use var and then along comes a maintainer who loves it, and extends the code using it. So now you have an unholy mess.

Standards are a good thing precisely because they mean you're that much more likely to be able to pick up random code and be able to grok it quickly. The more things that are different, the harder that gets. And moving to the 'var everywhere' style makes a big difference.

I don't mind dynamic typing, and I don't mind implict typing - in languages that are designed for them. I quite like Python. But C# was designed as a statically explicitly-typed language and that's how it should stay. Breaking the rules for anonymous types was bad enough; letting people take that still further and break the idioms of the language even more is something I'm not happy with. Now that the genie is out of the bottle, it'll never go back in. C# will become balkanised into camps. Not good.

If there are up to 10 strings then you should use a list in order to iterate through all values.

{% set list1 = variable1.split(';') %}
{% for list in list1 %}
<p>{{ list }}</p>
{% endfor %}

Using figure environment and .set_clim()

Could be easier and safer this alternative if you have multiple plots:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )
data1 = np.clip(data,0,6)
data2 = np.clip(data,-6,0)
vmin = np.min(np.array([data,data1,data2]))
vmax = np.max(np.array([data,data1,data2]))

fig = plt.figure()
ax = fig.add_subplot(131)
mesh = ax.pcolormesh(data, cmap = cm)
mesh.set_clim(vmin,vmax)
ax1 = fig.add_subplot(132)
mesh1 = ax1.pcolormesh(data1, cmap = cm)
mesh1.set_clim(vmin,vmax)
ax2 = fig.add_subplot(133)
mesh2 = ax2.pcolormesh(data2, cmap = cm)
mesh2.set_clim(vmin,vmax)
# Visualizing colorbar part -start
fig.colorbar(mesh,ax=ax)
fig.colorbar(mesh1,ax=ax1)
fig.colorbar(mesh2,ax=ax2)
fig.tight_layout()
# Visualizing colorbar part -end

plt.show()

A single colorbar

The best alternative is then to use a single color bar for the entire plot. There are different ways to do that, this tutorial is very useful for understanding the best option. I prefer this solution that you can simply copy and paste instead of the previous visualizing colorbar part of the code.

fig.subplots_adjust(bottom=0.1, top=0.9, left=0.1, right=0.8,
                    wspace=0.4, hspace=0.1)
cb_ax = fig.add_axes([0.83, 0.1, 0.02, 0.8])
cbar = fig.colorbar(mesh, cax=cb_ax)

P.S.

I would suggest using pcolormesh instead of pcolor because it is faster (more infos here ).

Below is one of the way by which you can achieve that, may not be an ideal way to do.

Have one method accepting both types of request, then check what type of request you received, is it of type "GET" or "POST", once you come to know that, do respective actions and the call one method which does common task for both request Methods ie GET and POST.

@RequestMapping(value = "/books")
public ModelAndView listBooks(HttpServletRequest request){
     //handle both get and post request here
     // first check request type and do respective actions needed for get and post.

    if(GET REQUEST){

     //WORK RELATED TO GET

    }else if(POST REQUEST){

      //WORK RELATED TO POST

    }

    commonMethod(param1, param2....);
}

Quote from xlsxwriter module documentation:

This module cannot be used to modify or write to an existing Excel XLSX file.

If you want to modify existing xlsx workbook, consider using openpyxl module.

See also:

• Modify an existing Excel file using Openpyxl in Python
• Use openpyxl to edit a Excel2007 file (.xlsx) without changing its own styles?

Since the question refers to a single element, this code might be more suitable:

// Checks CSS content for display:[none|block], ignores visibility:[true|false]
$(element).is(":visible");

// The same works with hidden
$(element).is(":hidden");

It is the same as twernt's suggestion, but applied to a single element; and it matches the algorithm recommended in the jQuery FAQ.

We use jQuery's is() to check the selected element with another element, selector or any jQuery object. This method traverses along the DOM elements to find a match, which satisfies the passed parameter. It will return true if there is a match, otherwise return false.

Here is a simple solution in C++11 which gives you satisfying resolution.

#include <iostream>
#include <chrono>

class Timer
{
public:
    Timer() : beg_(clock_::now()) {}
    void reset() { beg_ = clock_::now(); }
    double elapsed() const { 
        return std::chrono::duration_cast<second_>
            (clock_::now() - beg_).count(); }

private:
    typedef std::chrono::high_resolution_clock clock_;
    typedef std::chrono::duration<double, std::ratio<1> > second_;
    std::chrono::time_point<clock_> beg_;
};

Or on *nix, for c++03

#include <iostream>
#include <ctime>

class Timer
{
public:
    Timer() { clock_gettime(CLOCK_REALTIME, &beg_); }

    double elapsed() {
        clock_gettime(CLOCK_REALTIME, &end_);
        return end_.tv_sec - beg_.tv_sec +
            (end_.tv_nsec - beg_.tv_nsec) / 1000000000.;
    }

    void reset() { clock_gettime(CLOCK_REALTIME, &beg_); }

private:
    timespec beg_, end_;
};

Here is the example usage:

int main()
{
    Timer tmr;
    double t = tmr.elapsed();
    std::cout << t << std::endl;

    tmr.reset();
    t = tmr.elapsed();
    std::cout << t << std::endl;

    return 0;
}
