For "Visual Studio Team Test" it appears you apply the ExpectedException attribute to the test's method.

Sample from the documentation here: A Unit Testing Walkthrough with Visual Studio Team Test

[TestMethod]
[ExpectedException(typeof(ArgumentException),
    "A userId of null was inappropriately allowed.")]
public void NullUserIdInConstructor()
{
   LogonInfo logonInfo = new LogonInfo(null, "P@ss0word");
}

Not exactly the same as NUnit's Value (or TestCase) attributes, but MSTest has the DataSource attribute, which allows you to do a similar thing.

You can hook it up to database or XML file - it is not as straightforward as NUnit's feature, but it does the job.

What you can do is select everything into a new instance of Course, and afterwards convert them to a List.

var qry = from a in obj.tbCourses
                     select new Course() {
                         Course.Property = a.Property
                         ...
                     };

qry.toList<Course>();

For your property example do:

mvn install "-Dmyproperty=my property from command line"

Note quotes around whole property definition. You'll need them if your property contains spaces.

In case you need it as a Class, you can extend it with dict and use update method:

Class a(dict):
  # some stuff
  self.update(b)

This worked for me:

brew uninstall openssl
brew tap-new $USER/old-openssl
brew extract --version=1.0.2t openssl $USER/old-openssl
brew install [email protected]

Edit: After updating to appcompat-v7:22.1.1 and using AppCompatActivity instead of ActionBarActivity my styles.xml looks like:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Note: This means I am using a Toolbar provided by the framework (NOT included in an XML file).

This worked for me:
styles.xml file:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Update: A quote from Gabriele Mariotti's blog.

With the new Toolbar you can apply a style and a theme. They are different! The style is local to the Toolbar view, for example the background color. The app:theme is instead global to all ui elements inflated in the Toolbar, for example the color of the title and icons.

The parameters that you are passing into the DrawImage method should be the size you want the image on the paper rather than the size of the image itself, the DrawImage command will then take care of the scaling for you. Probably the easiest way is to use the following override of the DrawImage command.

args.Graphics.DrawImage(i, args.MarginBounds);

Note: This will skew the image if the proportions of the image are not the same as the rectangle. Some simple math on the size of the image and paper size will allow you to create a new rectangle that fits in the bounds of the paper without skewing the image.

Here's an example that only uses a Left join and I believe is more efficient than any group by method out there: ExchangeCore Blog

SELECT t1.*
FROM TrainTable t1 LEFT JOIN TrainTable t2
ON (t1.Train = t2.Train AND t1.Time < t2.Time)
WHERE t2.Time IS NULL;

After trying some ways to load the file with no success, I remembered I could use FileInputStream, which worked perfectly.

InputStream is = new FileInputStream("file.txt");

This is another way to read a file into an InputStream, it reads the file from the currently running folder.

Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.

You can also use CSS3 flexbox layout, which is well supported nowadays.

.container {
    display: flex;
    flex-flow: row nowrap;
    justify-content: space-between;
    background:black;
    height:400px;
    width:450px;
}

.left {
    flex: 0 0 300px;
    background:blue;
    height:200px;
}

.right {
    flex: 0 1 100px;
    background:green;
    height:300px;
}

See Example (with legacy styles for maximum compatiblity) & Learn more about flexbox.

Meanwhile, another reason : accidentally deleted the .config file caused the same error message appears:

"Service on local computer started and then stopped. some services stop automatically..."

Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!

import pandas as pd
import numpy as np

df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )

# Create an index list from the set of dates in both data frames
Index = list(set(list(df1.index) + list(df2.index)))
Index.sort()

df3 = pd.DataFrame({'df1': [df1.loc[Date, 'c'] if Date in df1.index else np.nan for Date in Index],\
                'df2': [df2.loc[Date, 'c'] if Date in df2.index else np.nan for Date in Index],},\
                index = Index)

df3

The first argument to a shell script is available as the variable $1, so the simplest implementation would be

if [ "$1" == "-h" ]; then
  echo "Usage: `basename $0` [somestuff]"
  exit 0
fi

But what anubhava said.

I had an old Excel database with "human-readable" dates, like 2010.03.28 20:12:30 Theese dates were in UTC+1 (CET) and needed to convert it to epoch time.

I used the =(A4-DATE(1970;1;1))*86400-3600 formula to convert the dates to epoch time from the A column to B column values. Check your timezone offset and make a math with it. 1 hour is 3600 seconds.

The only thing why i write here an anwser, you can see that this topic is more than 5 years old is that i use the new Excel versions and also red posts in this topic, but they're incorrect. The DATE(1970;1;1). Here the 1970 and the January needs to be separated with ; and not with ,

If you're also experiencing this issue, hope it helps you. Have a nice day :)

I am not clear exactly what your situation requires but the following may get you started. The key here is using ThisWorkbook.Path to get a relative file path:

Sub SaveToRelativePath()
    Dim relativePath As String
    relativePath = ThisWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
    ActiveWorkbook.SaveAs Filename:=relativePath
End Sub

I have the solution for this due to I have a similar problem today.

Supposed you want to open http://google.com from an app running with admin priviliges:

ProcessStartInfo startInfo = new ProcessStartInfo("iexplore.exe", "http://www.google.com/");
Process.Start(startInfo); 

<?php 
include("config.php");
 
 
$id=$_GET['id'];

include("config.php");
if($insert = mysqli_query($con,"update  consumer_closeconnection set close_status='Pending' where id="$id"  "))
            {
?>
<script>
    window.location.href='ConsumerCloseConnection.php';

</script>
<?php
            }
            else
            {
?>
<script>
     window.location.href='ConsumerCloseConnection.php';
</script>
<?php            
    }
?>      

Maybe you could abstract this as a dependency and create an IVirtualPathResolver. This way your service classes wouldn't be bound to System.Web and you could create another implementation if you wanted to reuse your logic in a different UI technology.

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

So in your build.gradle file, add this:

compile 'com.android.support:design:27.1.1'

AndroidX Note: Google is introducing new AndroidX extension libraries to replace the older Support Libraries. To use AndroidX, first make sure you've updated your gradle.properties file, edited build.gradle to set compileSdkVersion to 28 (or higher), and use the following line instead of the previous compile one.

implementation 'com.google.android.material:material:1.0.0'

Next, in your themes.xml or styles.xml or whatever, make sure you set this- it's your app's accent color-- and the color of your FAB unless you override it (see below):

        <item name="colorAccent">@color/floating_action_button_color</item>

In the layout's XML:

<RelativeLayout
 ...
 xmlns:app="http://schemas.android.com/apk/res-auto">

       <android.support.design.widget.FloatingActionButton
            android:id="@+id/myFAB"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_plus_sign"
            app:elevation="4dp"
            ... />

</RelativeLayout>

Or if you are using the AndroidX material library above, you'd instead use this:

<RelativeLayout
 ...
 xmlns:app="http://schemas.android.com/apk/res-auto">

       <com.google.android.material.floatingactionbutton.FloatingActionButton
            android:id="@+id/myFAB"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:srcCompat="@drawable/ic_plus_sign"
            app:elevation="4dp"
            ... />

</RelativeLayout>

You can see more options in the docs (material docs here) (setRippleColor, etc.), but one of note is:

    app:fabSize="mini"

Another interesting one-- to change the background color of just one FAB, add:

    app:backgroundTint="#FF0000"

(for example to change it to red) to the XML above.

Anyway, in code, after the Activity/Fragment's view is inflated....

    FloatingActionButton myFab = (FloatingActionButton)  myView.findViewById(R.id.myFAB);
    myFab.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            doMyThing();
        }
    });

Observations:

• If you have one of those buttons that's on a "seam" splitting two views (using a RelativeLayout, for example) with, say, a negative bottom layout margin to overlap the border, you'll notice an issue: the FAB's size is actually very different on lollipop vs. pre-lollipop. You can actually see this in AS's visual layout editor when you flip between APIs-- it suddenly "puffs out" when you switch to pre-lollipop. The reason for the extra size seems to be that the shadow expands the size of the view in every direction. So you have to account for this when you're adjusting the FAB's margins if it's close to other stuff.

• Here's a way to remove or change the padding if there's too much:

  if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
      RelativeLayout.LayoutParams p = (RelativeLayout.LayoutParams) myFab.getLayoutParams();
      p.setMargins(0, 0, 0, 0); // get rid of margins since shadow area is now the margin
      myFab.setLayoutParams(p);
  }
  

• Also, I was going to programmatically place the FAB on the "seam" between two areas in a RelativeLayout by grabbing the FAB's height, dividing by two, and using that as the margin offset. But myFab.getHeight() returned zero, even after the view was inflated, it seemed. Instead I used a ViewTreeObserver to get the height only after it's laid out and then set the position. See this tip here. It looked like this:

      ViewTreeObserver viewTreeObserver = closeButton.getViewTreeObserver();
      if (viewTreeObserver.isAlive()) {
          viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
              @Override
              public void onGlobalLayout() {
                  if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
                      closeButton.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                  } else {
                      closeButton.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                  }
                  // not sure the above is equivalent, but that's beside the point for this example...
                  RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) closeButton.getLayoutParams();
                  params.setMargins(0, 0, 16, -closeButton.getHeight() / 2); // (int left, int top, int right, int bottom)
                  closeButton.setLayoutParams(params);
              }
          });
      }
  

  Not sure if this is the right way to do it, but it seems to work.

• It seems you can make the shadow-space of the button smaller by decreasing the elevation.

• If you want the FAB on a "seam" you can use layout_anchor and layout_anchorGravity here is an example:

  <android.support.design.widget.FloatingActionButton
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      app:layout_anchor="@id/appbar"
      app:layout_anchorGravity="bottom|right|end"
      android:src="@drawable/ic_discuss"
      android:layout_margin="@dimen/fab_margin"
      android:clickable="true"/>
  

Remember that you can automatically have the button jump out of the way when a Snackbar comes up by wrapping it in a CoordinatorLayout.

The two commands (reset and checkout) are completely different.

checkout X IS NOT reset --hard X

If X is a branch name, checkout X will change the current branch while reset --hard X will not.

The already mentioned "all-or-nothing" approach was the reason I'm usually using Ant instead ... Far more often you get to work on a "legacy" project, that already has a defined structure that you can't change just because Maven wants things otherwise.

Ant on the other hand can be used anytime, no matter the projects disorganization.

Regarding the alternatives, I've read good things about rake.

( Btw, I'm talking about Maven 1, haven't yet looked into Maven 2 )

The name accepted into TR1 (and the draft for the next standard) is std::unordered_map, so if you have that available, it's probably the one you want to use.

Other than that, using it is a lot like using std::map, with the proviso that when/if you traverse the items in an std::map, they come out in the order specified by operator<, but for an unordered_map, the order is generally meaningless.

Try installing the 'Application Development' sub component of IIS as mentioned in this SO

• Click "Start button" in the search box, enter "Turn windows features on or off"
• in the features window, Click: "Internet Information Services"
• Click: "World Wide Web Services"
• Click: "Application Development Features"
• Check (enable) the features. I checked all but CGI.

Try going to Window -> Preferences -> Nodeclipse and unchecking the box that says "find node on PATH...". Then make sure the "Node.js path" below is set to the location of the node.exe file (for me it was C:\Program Files (x86)\nodejs\node.exe).

The easiest option is to make use of the Excel copy/paste.

Public Sub insertRowBelow()
ActiveCell.Offset(1).EntireRow.Insert Shift:=xlDown, CopyOrigin:=xlFormatFromRightOrAbove
ActiveCell.EntireRow.Copy
ActiveCell.Offset(1).EntireRow.PasteSpecial xlPasteFormats
Application.CutCopyMode = False
End Sub

1. Restore Object From File

From Here you can deserialize an object from file in two way.

Solution-1: Read file into a string and deserialize JSON to a type

string json = File.ReadAllText(@"c:\myObj.json");
MyObject myObj = JsonConvert.DeserializeObject<MyObject>(json);

Solution-2: Deserialize JSON directly from a file

using (StreamReader file = File.OpenText(@"c:\myObj.json"))
{
    JsonSerializer serializer = new JsonSerializer();
    MyObject myObj2 = (MyObject)serializer.Deserialize(file, typeof(MyObject));
}

2. Save Object To File

from here you can serialize an object to file in two way.

Solution-1: Serialize JSON to a string and then write string to a file

string json = JsonConvert.SerializeObject(myObj);
File.WriteAllText(@"c:\myObj.json", json);

Solution-2: Serialize JSON directly to a file

using (StreamWriter file = File.CreateText(@"c:\myObj.json"))
{
    JsonSerializer serializer = new JsonSerializer();
    serializer.Serialize(file, myObj);
}

3. Extra

You can download Newtonsoft.Json from NuGet by following command

Install-Package Newtonsoft.Json

The command clang is for C, and the command clang++ is for C++.

You can use command line tool to build the release version. Next to your project folder, i.e.

$ ls
...
Foo.xcodeproj
...

Type the following build command:

$ xcodebuild -configuration Release

In my case the issue was a missing 's' in the HTTP URL. Error was: "HttpHostConnectException: Connect to someendpoint.com:80 [someendpoint.com/127.0.0.1] failed: Connection refused" End point and IP obviously changed to protect the network.

In my case php was upgraded from php7.2.22 to php7.3.9.

so had to downgrade cli php as composer is run on terminal

//checked php version
php -v //was 7.3.9

//changed cli version back to 7.2
sudo update-alternatives --set php /usr/bin/php7.2
sudo update-alternatives --set phar /usr/bin/phar7.2
sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.2
sudo update-alternatives --set phpize /usr/bin/phpize7.2
sudo update-alternatives --set php-config /usr/bin/php-config7.2

//checked php version 
php -v //was 7.2.22

additional info if you are using apache remember to keep both cli and apache in same version. in my case i had to downgrade

//changed web version back to 7.2
sudo a2dismod php7.3
sudo a2enmod php7.2
sudo service apache2 restart

This will work with other versions. so feel free to switch between versions. just replace the version numbers appropriately

I had this problem, and it is super simple to fix.

Get two containers. The inner will be your scrollable container and the outer will obviously house the inner:

#inner_container { width: 102%; overflow: auto; }
#outer_container { overflow: hidden }

It is super simple and should work with any browser.

Clean your variable by removing all the carriage returns:

COMMAND=$(echo $COMMAND|tr -d '\n')

 SELECT id, GROUP_CONCAT(CONCAT_WS(':', Name, CAST(Value AS CHAR(7))) SEPARATOR ',') AS result 
    FROM test GROUP BY id

you must use cast or convert, otherwise will be return BLOB

result is

id         Column
1          A:4,A:5,B:8
2          C:9

you have to handle result once again by program such as python or java

Here is how I made monthly page in similar manner as Fernando:

1. I wrote manually on each page number of the month and named that place as ThisMonth. Note that you can do this only before you make copies of the sheet. After copying Excel doesn't allow you to use same name, but with sheet copy it does it still. This solution works also without naming.
2. I added number of weeks in the month to location C12. Naming is fine also.

3. I made five weeks on every page and on fifth week I made function

     =IF(C12=5,DATE(YEAR(B48),MONTH(B48),DAY(B48)+7),"")
   

   that empties fifth week if this month has only four weeks. C12 holds the number of weeks.

4. ...
5. I created annual Excel, so I had 12 sheets in it: one for each month. In this example name of the sheet is "Month". Note that this solutions works also with the ODS file standard except you need to change all spaces as "_" characters.
6. I renamed first "Month" sheet as "Month (1)" so it follows the same naming principle. You could also name it as "Month1" if you wish, but "January" would require a bit more work.

7. Insert following function on the first day field starting sheet #2:

    =INDIRECT(CONCATENATE("'Month (",ThisMonth-1,")'!B15"))+INDIRECT(CONCATENATE("'Month (",ThisMonth-1,")'!C12"))*7
   

   So in another word, if you fill four or five weeks on the previous sheet, this calculates date correctly and continues from correct date.

You were missing a few important sonar properties, Here is a sample from one of my builds:

sonar.jdbc.dialect=mssql
sonar.projectKey=projectname
sonar.projectName=Project Name
sonar.projectVersion=1.0
sonar.sources=src
sonar.language=java
sonar.binaries=build/classes
sonar.tests=junit
sonar.dynamicAnalysis=reuseReports
sonar.junit.reportsPath=build/test-reports
sonar.java.coveragePlugin=jacoco
sonar.jacoco.reportPath=build/test-reports/jacoco.exec

The error in Jenkins console output can be pretty useful for getting code coverage to work.

Project coverage is set to 0% since there is no directories with classes.
Indicates that you have not set the Sonar.Binaries property correctly

No information about coverage per test
Indicates you have not set the Sonar.Tests property properly

Coverage information was not collected. Perhaps you forget to include debug information into compiled classes? Indicates that the sonar.binaries property was set correctly, but those files were not compiled in debug mode, and they need to be

OR

you can write this down in your program

Private Sub ComboBoxExp_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)Handles MyBase.Load
    AlarmHourSelect.Text = "YOUR DEFAULT VALUE"
    AlarmMinuteSelect.Text = "YOUR DEFAULT VALUE"
End Sub

so when you start your program, the first thing it would do is set it on your assigned default value and later you can easily select your required option from the drop down list. also keeping the DropDownStyle to DropDownList would make it look more cooler.

-Starkternate

I recently came up with a one-line solution that accomplishes exactly this for a JS challenge on Scrimba (below).

ES6+

const getPrimes=num=>Array(num-1).fill().map((e,i)=>2+i).filter((e,i,a)=>a.slice(0,i).every(x=>e%x!==0));

< ES6

function getPrimes(num){return ",".repeat(num).slice(0,-1).split(',').map(function(e,i){return i+1}).filter(function(e){return e>1}).filter(function(x){return ",".repeat(x).slice(0,-1).split(',').map(function(f,j){return j}).filter(function(e){return e>1}).every(function(e){return x%e!==0})})};

This is the logic explained:

1. First, the function builds an array of all numbers leading up to the desired number (in this case, 100) via the .repeat() function using the desired number (100) as the repeater argument and then mapping the array to the indexes+1 to get the range of numbers from 0 to that number (0-100). A bit of string splitting and joining magic going on here. I'm happy to explain this step further if you like.

2. We exclude 0 and 1 from the array as they should not be tested for prime, lest they give a false positive. Neither are prime. We do this using .filter() for only numbers > 1 (= 2).

3. Now, we filter our new array of all integers between 2 and the desired number (100) for only prime numbers. To filter for prime numbers only, we use some of the same magic from our first step. We use .filter() and .repeat() once again to create a new array from 2 to each value from our new array of numbers. For each value's new array, we check to see if any of the numbers = 2 and < that number are factors of the number. We can do this using the .every() method paired with the modulo operator % to check if that number has any remainders when divided by any of those values between 2 and itself. If each value has remainders (x%e!==0), the condition is met for all values from 2 to that number (but not including that number, i.e.: [2,99]) and we can say that number is prime. The filter functions returns all prime numbers to the uppermost return, thereby returning the list of prime values between 2 and the passed value.

As an example, using one of these functions I've added above, returns the following:

getPrimes(100);
// => [2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97]

You can use one of the following.

• $! is the PID of the last backgrounded process.
• kill -0 $PID checks whether it's still running.
• $$ is the PID of the current shell.

You can do it like this:

uint8_t (*matrix_ptr)[10][20] = &l_matrix;

Some addition to previous comments: 'firstboot' won't be available until you run 'mount_root' command.

So here is a full recap of what needs to be done. All manipulations I did on Windows 8.1.

• Enter Failsafe mode (hold the reset button on boot for a few seconds)
• Assign a static IP address, 192.168.1.2, to your PC. Example of a command: netsh interface ip set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1
• Connect to address 192.168.1.1 from telnet (I use PuTTY) and login/password isn't required).
• Run 'mount_root' (otherwise 'firstboot' won't be available).
• Run 'firstboot' to reset.
• Run 'reboot -f' to reboot.

Now you can enter to the router console from a browser. Also don't forget to return your PC from static to DHCP address assignment. Example: netsh interface ip set address name="Ethernet" source=dhcp

Based on the git documentation the best way is:

1. be sure the actual origin path:

git remote -v

3. Then make the change with:

git remote set-url origin

where url-repository is the same URL that we get from the clone option.

I was getting same kinda error but after copying the ojdbc14.jar into lib folder, no more exception.(copy ojdbc14.jar from somewhere and paste it into lib folder inside WebContent.)

Unlike in C# where you have the Array.IndexOf method, and JavaScript where you have the indexOf method, Java's API (the Array and Arrays classes in particular) have no such method.

This method indexOf (together with its complement lastIndexOf) is defined in the java.util.List interface. Note that indexOf and lastIndexOf are not overloaded and only take an Object as a parameter.

If your array is sorted, you are in luck because the Arrays class defines a series of overloads of the binarySearch method that will find the index of the element you are looking for with best possible performance (O(log n) instead of O(n), the latter being what you can expect from a sequential search done by indexOf). There are four considerations:

1. The array must be sorted either in natural order or in the order of a Comparator that you provide as an argument, or at the very least all elements that are "less than" the key must come before that element in the array and all elements that are "greater than" the key must come after that element in the array;

2. The test you normally do with indexOf to determine if a key is in the array (verify if the return value is not -1) does not hold with binarySearch. You need to verify that the return value is not less than zero since the value returned will indicate the key is not present but the index at which it would be expected if it did exist;

3. If your array contains multiple elements that are equal to the key, what you get from binarySearch is undefined; this is different from indexOf that will return the first occurrence and lastIndexOf that will return the last occurrence.

4. An array of booleans might appear to be sorted if it first contains all falses and then all trues, but this doesn't count. There is no override of the binarySearch method that accepts an array of booleans and you'll have to do something clever there if you want O(log n) performance when detecting where the first true appears in an array, for instance using an array of Booleans and the constants Boolean.FALSE and Boolean.TRUE.

If your array is not sorted and not primitive type, you can use List's indexOf and lastIndexOf methods by invoking the asList method of java.util.Arrays. This method will return an AbstractList interface wrapper around your array. It involves minimal overhead since it does not create a copy of the array. As mentioned, this method is not overloaded so this will only work on arrays of reference types.

If your array is not sorted and the type of the array is primitive, you are out of luck with the Java API. Write your own for loop, or your own static utility method, which will certainly have performance advantages over the asList approach that involves some overhead of an object instantiation. In case you're concerned that writing a brute force for loop that iterates over all of the elements of the array is not an elegant solution, accept that that is exactly what the Java API is doing when you call indexOf. You can make something like this:

public static int indexOfIntArray(int[] array, int key) {
    int returnvalue = -1;
    for (int i = 0; i < array.length; ++i) {
        if (key == array[i]) {
            returnvalue = i;
            break;
        }
    }
    return returnvalue;
}

If you want to avoid writing your own method here, consider using one from a development framework like Guava. There you can find an implementation of indexOf and lastIndexOf.

I'm not sure if this is the most pythonic method ... I had a list of tuples that needed sorting 1st by descending integer values and 2nd alphabetically. This required reversing the integer sort but not the alphabetical sort. Here was my solution: (on the fly in an exam btw, I was not even aware you could 'nest' sorted functions)

a = [('Al', 2),('Bill', 1),('Carol', 2), ('Abel', 3), ('Zeke', 2), ('Chris', 1)]  
b = sorted(sorted(a, key = lambda x : x[0]), key = lambda x : x[1], reverse = True)  
print(b)  
[('Abel', 3), ('Al', 2), ('Carol', 2), ('Zeke', 2), ('Bill', 1), ('Chris', 1)]

It's a syntax for array references - you need to use (&array) to clarify to the compiler that you want a reference to an array, rather than the (invalid) array of references int & array[100];.

EDIT: Some clarification.

void foo(int * x);
void foo(int x[100]);
void foo(int x[]);

These three are different ways of declaring the same function. They're all treated as taking an int * parameter, you can pass any size array to them.

void foo(int (&x)[100]);

This only accepts arrays of 100 integers. You can safely use sizeof on x

void foo(int & x[100]); // error

This is parsed as an "array of references" - which isn't legal.

Use this class for 30 min

        $_SESSION[$key] =$val;
    }
    public static function get($key){
        if(isset($_SESSION[$key])){
            return $_SESSION[$key];
        } else{
            return false;

Just to add to how to use map files. I use chrome for ubuntu and if I go to sources and click on a file, if there is a map file a message comes up telling me that I can view the original file and how to do it.

For the Angular files that I worked with today I click

Ctrl-P and a list of original files comes up in a small window.

I can then browse through the list to view the file that I would like to inspect and check where the issue might be.

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

see this answer also to see an image associated

(whish that the moderator realized this is the same question and instead of deleting my answer, he could mark one of the questions as duplicated to the other)

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

For Laravel 5.3 and above

Check Scott's answer below.

For Laravel 5 up to 5.2

Simply put,

On auth middleware:

// redirect the user to "/login"
// and stores the url being accessed on session
if (Auth::guest()) {
    return redirect()->guest('login');
}
return $next($request);

On login action:

// redirect the user back to the intended page
// or defaultpage if there isn't one
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return redirect()->intended('defaultpage');
}

For Laravel 4 (old answer)

At the time of this answer there was no official support from the framework itself. Nowadays you can use the method pointed out by bgdrl below this method: (I've tried updating his answer, but it seems he won't accept)

On auth filter:

// redirect the user to "/login"
// and stores the url being accessed on session
Route::filter('auth', function() {
    if (Auth::guest()) {
        return Redirect::guest('login');
    }
});

On login action:

// redirect the user back to the intended page
// or defaultpage if there isn't one
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return Redirect::intended('defaultpage');
}

For Laravel 3 (even older answer)

You could implement it like this:

Route::filter('auth', function() {
    // If there's no user authenticated session
    if (Auth::guest()) {
        // Stores current url on session and redirect to login page
        Session::put('redirect', URL::full());
        return Redirect::to('/login');
    }
    if ($redirect = Session::get('redirect')) {
        Session::forget('redirect');
        return Redirect::to($redirect);
    }
});

// on controller
public function get_login()
{
    $this->layout->nest('content', 'auth.login'); 
}

public function post_login()
{
    $credentials = [
        'username' => Input::get('email'),
        'password' => Input::get('password')
    ];

    if (Auth::attempt($credentials)) {
        return Redirect::to('logged_in_homepage_here');
    }

    return Redirect::to('login')->with_input();
}

Storing the redirection on Session has the benefit of persisting it even if the user miss typed his credentials or he doesn't have an account and has to signup.

This also allows for anything else besides Auth to set a redirect on session and it will work magically.

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

I used android.util.base64 that works pretty good without any dependances:

byte[] decodedKey = Base64.decode(encodedPublicKey, Base64.DEFAULT);

Check that the port that SQL Server is using is not being blocked by either your firewall or the VPN.

To pass the value you must included the hidden value value="hiddenValue" in the <input> statement like so:

<input type="hidden" id="thisField" name="inputName" value="hiddenValue">

Then you recuperate the hidden form value in the same way that you recuperate the value of visible input fields, by accessing the parameter of the request object. Here is an example:

This code goes on the page where you want to hide the value.

<form action="anotherPage.jsp" method="GET">
    <input type="hidden" id="thisField" name="inputName" value="hiddenValue">
<input type="submit">   
</form>

Then on the 'anotherPage.jsp' page you recuperate the value by calling the getParameter(String name) method of the implicit request object, as so:

<% String hidden = request.getParameter("inputName"); %>
The Hidden Value is <%=hidden %>

The output of the above script will be:

The Hidden Value is hiddenValue 

You can get the index value with this

foreach ($arr as $key => $val)
{
    $key = (int) $key;
    //With the variable $key you can get access to the current array index
    //You can use $val[$key] to

}

First, you should use any WebSocket or polling mechanics to notify the frontend part about changes that happened. I use Flask-SocketIO wrapper, and very happy with async messaging for my tiny apps.

Nest, you can do all logic which you need in a separate thread(s), and notify the frontend via SocketIO object (Flask holds continuous open connection with every frontend client).

As an example, I just implemented page reload on backend file modifications:

<!doctype html>
<script>
    sio = io()

    sio.on('reload',(info)=>{
        console.log(['sio','reload',info])
        document.location.reload()
    })
</script>

class App(Web, Module):

    def __init__(self, V):
        ## flask module instance
        self.flask = flask
        ## wrapped application instance
        self.app = flask.Flask(self.value)
        self.app.config['SECRET_KEY'] = config.SECRET_KEY
        ## `flask-socketio`
        self.sio = SocketIO(self.app)
        self.watchfiles()

    ## inotify reload files after change via `sio(reload)``
    def watchfiles(self):
        from watchdog.observers import Observer
        from watchdog.events import FileSystemEventHandler
        class Handler(FileSystemEventHandler):
            def __init__(self,sio):
                super().__init__()
                self.sio = sio
            def on_modified(self, event):
                print([self.on_modified,self,event])
                self.sio.emit('reload',[event.src_path,event.event_type,event.is_directory])
        self.observer = Observer()
        self.observer.schedule(Handler(self.sio),path='static',recursive=True)
        self.observer.schedule(Handler(self.sio),path='templates',recursive=True)
        self.observer.start()

Swift 3.0

Convert html to string and font change as per your requirement.

do {

     let str = try NSAttributedString(data: ("I'm a normal text and <b>this is my bold part . </b>And I'm again in the normal text".data(using: String.Encoding.unicode, allowLossyConversion: true)!), options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)

     myLabel.attributedText = str
     myLabel.font =  MONTSERRAT_BOLD(23)
     myLabel.textAlignment = NSTextAlignment.left
} catch {
     print(error)
}

func MONTSERRAT_BOLD(_ size: CGFloat) -> UIFont
{
    return UIFont(name: "MONTSERRAT-BOLD", size: size)!
}

thy this:

@UiThread
    public void logMsg(final String msg) {
        new Handler(Looper.getMainLooper()).post(new Runnable() {
            @Override
            public void run() {
                Log.d("UI thread", "I am the UI thread");


            }
        });
    }

I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

public abstract class ExternalScript extends Script {

    private String source;

    public void setSource(String file) {
        source = file;
    }

    public String getSource() {
        return source;
    }
}

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:

• If source was protected (so accessible by subclasses) then code gets messy: who's changing the variables? When it's an object it then becomes hard when you need to refactor, whereas a method tends to make this step easier.
• If your getter/setter methods aren't getting and setting, then describe them as something else.

Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.

You could also type 'conda list' in a command line. This will print out the installed modules with the version numbers. The path within your file structure will be printed at the top of this list.

We can increase maximum upload file size for WordPress media uploads in 3 different ways.

That's are

1. .htaccess way
2. PHP.INI file method
3. Theme’s Functions.php File

For .htaccess way, add following code,

php_value upload_max_filesize 1024M
php_value post_max_size 1024M
php_value max_execution_time 1000
php_value max_input_time 1000

for PHP.INI file method, add following code,

upload_max_filesize = 1024M
post_max_size = 1024M
max_execution_time = 1000

for Theme’s Functions.php File, add following code,

@ini_set( ‘upload_max_size’ , ’1024M’ );
@ini_set( ‘post_max_size’, ’1024M’);
@ini_set( ‘max_execution_time’, ’1000' );

I think it might be better to keep the binding the entire time, and simply update the data associated with it. I ran into this issue, and found that just calling using the .resetAll() method on the array in which I was keeping my data was the most effective way to do this.

Basically you can start with some global var which contains data to be rendered via the ViewModel:

var myLiveData = ko.observableArray();

It took me a while to realize I couldn't just make myLiveData a normal array -- the ko.oberservableArray part was important.

Then you can go ahead and do whatever you want to myLiveData. For instance, make a $.getJSON call:

$.getJSON("http://foo.bar/data.json?callback=?", function(data) {
    myLiveData.removeAll();
    /* parse the JSON data however you want, get it into myLiveData, as below */
    myLiveData.push(data[0].foo);
    myLiveData.push(data[4].bar);
});

Once you've done this, you can go ahead and apply bindings using your ViewModel as usual:

function MyViewModel() {
    var self = this;
    self.myData = myLiveData;
};
ko.applyBindings(new MyViewModel());

Then in the HTML just use myData as you normally would.

This way, you can just muck with myLiveData from whichever function. For instance, if you want to update every few seconds, just wrap that $.getJSON line in a function and call setInterval on it. You'll never need to remove the binding as long as you remember to keep the myLiveData.removeAll(); line in.

Unless your data is really huge, user's won't even be able to notice the time in between resetting the array and then adding the most-current data back in.

How about Excel Data Reader?

http://exceldatareader.codeplex.com/

I've used in it anger, in a production environment, to pull large amounts of data from a variety of Excel files into SQL Server Compact. It works very well and it's rather robust.

Asynchronous is there for a reason! Throws stone at @mihai

Otherwise, here is the code he used with the asynchronous version:

// Declare variables
var fs = require('fs'),
    obj

// Read the file and send to the callback
fs.readFile('path/to/file', handleFile)

// Write the callback function
function handleFile(err, data) {
    if (err) throw err
    obj = JSON.parse(data)
    // You can now play with your datas
}

Input the following to your Apache configuration:

php_value memory_limit 2048M

I second Dave's idea. I'm not always fond of pivot tables, but in this case they are pretty straightforward to use.

Here are my results:

It was so simple to create it that I have even recorded a macro in case you need to do this with VBA:

Sub Macro2()
'
' Macro2 Macro
'

'
    Range("Table1[[#All],[DATA]]").Select
    ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
        "Table1", Version:=xlPivotTableVersion14).CreatePivotTable TableDestination _
        :="Sheet3!R3C7", TableName:="PivotTable4", DefaultVersion:= _
        xlPivotTableVersion14
    Sheets("Sheet3").Select
    Cells(3, 7).Select
    With ActiveSheet.PivotTables("PivotTable4").PivotFields("DATA")
        .Orientation = xlRowField
        .Position = 1
    End With
    ActiveSheet.PivotTables("PivotTable4").AddDataField ActiveSheet.PivotTables( _
        "PivotTable4").PivotFields("DATA"), "Count of DATA", xlCount
End Sub

UPDATE: if you're searching for a solution in 2020 backed by Kotlin Coroutines, try Coil.

Coil is an acronym for Coroutine Image Loader.

Features

1. Fast: Coil performs a number of optimizations including memory and disk caching, downsampling the image in memory, re-using bitmaps, automatically pausing/cancelling requests, and more.
2. Lightweight: Coil adds ~2000 methods to your APK (for apps that already use OkHttp and Coroutines), which is comparable to Picasso and significantly less than Glide and Fresco.
3. Easy to use: Coil's API leverages Kotlin's language features for simplicity and minimal boilerplate.
4. Modern: Coil is Kotlin-first and uses modern libraries including Coroutines, OkHttp, Okio, and AndroidX Lifecycles.

Gradle Setup:

Coil is available on mavenCentral().

implementation("io.coil-kt:coil:1.0.0")

Quick Start

To load an image into an ImageView, use the load extension function:

// URL
imageView.load("https://www.example.com/image.jpg")

// Resource
imageView.load(R.drawable.image)

// File
imageView.load(File("/path/to/image.jpg"))

or on Background threads

// Coil (suspends the current coroutine; non-blocking and thread safe)
val request = ImageRequest.Builder(context)
    .data(url)
    .size(width, height)
    .build()
val drawable = context.imageLoader.execute(request).drawable

You can also migrate from Picasso/Glide

Full documentation here

you can use this too

.parent:hover * {
   /* ... */
}

I'm very late to the party here, but if you use an IDE like PyCharm, there's an option in 'Edit Configurations' under the 'Run' menu (Run > Edit Configurations) where you can specify a default port. This of course is relevant only if you are debugging/testing through PyCharm.

As previously mentioned, best practice is del(); or pop() if you need to know the value.

An alternate solution is to re-stack only those elements you want:

    a = ['a', 'b', 'c', 'd'] 

    def remove_element(list_,index_):
        clipboard = []
        for i in range(len(list_)):
            if i is not index_:
                clipboard.append(list_[i])
        return clipboard

    print(remove_element(a,2))

    >> ['a', 'b', 'd']

eta: hmm... will not work on negative index values, will ponder and update

I suppose

if index_<0:index_=len(list_)+index_

would patch it... but suddenly this idea seems very brittle. Interesting thought experiment though. Seems there should be a 'proper' way to do this with append() / list comprehension.

pondering

If your column data type is 'text' then you will get an error message as

Msg 8116, Level 16, State 1, Line 2 Argument data type text is invalid for argument 1 of replace function.

In this case you need to cast the text as nvarchar and then replace

SELECT REPLACE(REPLACE(cast(@str as nvarchar(max)), CHAR(13), ''), CHAR(10), '')

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

How about:

function sliceObj(obj) {
  var o = {}
    , keys = [].slice.call(arguments, 1);
  for (var i=0; i<keys.length; i++) {
    if (keys[i] in obj) o[keys[i]] = obj[keys[i]];
  }
  return o;
}

var subset = sliceObj(elmo, 'color', 'height');

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

Yup. Function references are just like any other object reference, you can pass them around to your heart's content.

Here's a more concrete example:

function foo() {
    console.log("Hello from foo!");
}

function caller(f) {
    // Call the given function
    f();
}

function indirectCaller(f) {
    // Call `caller`, who will in turn call `f`
    caller(f);
}

// Do it
indirectCaller(foo); // logs "Hello from foo!"

You can also pass in arguments for foo:

function foo(a, b) {
    console.log(a + " + " + b + " = " + (a + b));
}

function caller(f, v1, v2) {
    // Call the given function
    f(v1, v2);
}

function indirectCaller(f, v1, v2) {
    // Call `caller`, who will in turn call `f`
    caller(f, v1, v2);
}

// Do it
indirectCaller(foo, 1, 2); // logs "1 + 2 = 3"

You can try using my custom view, which has capability to blur the background. It does this by faking taking snapshot of the background and blur it, just like the one in Apple's WWDC code. It is very simple to use.

I also made some improvement over to fake the dynamic blur without losing the performance. The background of my view is a scrollView which scrolls with the view, thus provide the blur effect for the rest of the superview.

See the example and code on my GitHub

When you mark your method as @Transactional, occurrence of any exception inside your method will mark the surrounding TX as roll-back only (even if you catch them). You can use other attributes of @Transactional annotation to prevent it of rolling back like:

@Transactional(rollbackFor=MyException.class, noRollbackFor=MyException2.class)

You almost had it with Not. It should be:

if (-Not (Test-Path C:\Code)) {
    write "it doesn't exist!"
} 

You can also use !: if (!(Test-Path C:\Code)){}

Just for fun, you could also use bitwise exclusive or, though it's not the most readable/understandable method.

if ((test-path C:\code) -bxor 1) {write "it doesn't exist!"}

Hello friends if your getting any not class found exception in hibernate code it is the problem of jar files.here mainly two problems
1.I mean to say your working old version of hibernate may be 3.2 bellow.So if u try above 3.6 it will works fine

2.first checkes database connection.if it database working properly their was a mistake in ur program or jar file.

please check these two prioblems if it also not working you tried to IDE . I am using netbeanside 6.9 version.here hibernate working fine.you dont get any error from class not founnd exception..

I hope this one helps more

So why is td default set to vertical-align: top;? I really don't know that yet. I would not dare to touch it. Instead add this to your stylesheet. It alters the buttons in the tables.

table .btn{
  vertical-align: top;
}

There is no difference between the two, one is just a shorthand for the second.

The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

<!-- full syntax -->
<a v-on:click="doSomething"></a>
<!-- shorthand -->
<a @click="doSomething"></a>

--- Update Angular 9 and Rxjs 6 Solution

1. Using unsubscribe at ngDestroy lifecycle of Angular Component

class SampleComponent implements OnInit, OnDestroy {
  private subscriptions: Subscription;
  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$.subscribe( ... );
  }

  ngOnDestroy() {
    this.subscriptions.unsubscribe();
  }
}

2. Using takeUntil in Rxjs

class SampleComponent implements OnInit, OnDestroy {
  private unsubscribe$: new Subject<void>;
  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$
    .pipe(takeUntil(this.unsubscribe$))
    .subscribe( ... );
  }

  ngOnDestroy() {
    this.unsubscribe$.next();
    this.unsubscribe$.complete();
  }
}

3. for some action that you call at ngOnInit that just happen only one time when component init.

class SampleComponent implements OnInit {

  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$
    .pipe(take(1))
    .subscribe( ... );
  }
}

We also have async pipe. But, this one use on the template (not in Angular component).

var result = (35.8 / 100) * 10000;

(Thank you jball for this change of order of operations. I didn't consider it).

Version 3.8 or newer:

To show line numbers in the current window, go to Options and click Show Line Numbers.

To show them automatically, go to Options > Configure IDLE > General and check the Show line numbers in new windows box.

Version 3.7 or older:

Unfortunately there is not an option to display line numbers in IDLE although there is an enhancement request open for this.

However, there are a couple of ways to work around this:

1. Under the edit menu there is a go to line option (there is a default shortcut of Alt+G for this).

2. There is a display at the bottom right which tells you your current line number / position on the line:

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

Use system property:

-Duser.timezone=UTC

ActiveSheet.UsedRange.Rows(ActiveSheet.UsedRange.Rows.count).row

ActiveSheet can be replaced with WorkSheets(1) or WorkSheets("name here")

The original form is nearly perfect, you just have to omit prereq after CASE:

SELECT
  CASE
    WHEN prereq IS NULL THEN ' '
    ELSE prereq
  END AS prereq
FROM test;

As you didn't give us very much information, I'm assuming the language you're writing the code in is C#. First of all: Prefer System.Collections.Generic.List over an ArrayList. Secondly: One way would be to loop through every item in the list and check whether it contains "How". Another way would be to use LINQ. Here's a quick example that filters out every item which doesn't contain "How":

var list = new List<string>();
list.AddRange(new string[] {
    "How are you?",
    "How you doing?",
    "Joe",
    "Mike", });

foreach (string str in list.Where(s => s.Contains("How")))
{
    Console.WriteLine(str);
}
Console.ReadLine();

Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.

I hope this answers the intent of the question. Although there are no Booleans in SQL Server, if you have a database that had Boolean types that was translated from Access, the phrase which works in Access was "...WHERE Foo" (Foo is the Boolean column name). It can be replaced by "...WHERE Foo<>0" ... and this works. Good luck!

Actually, it is best if you use a try-with-resources block and Java will close all of the connections for you when you exit the try block.

You should do this with any object that implements AutoClosable.

try (Connection connection = getDatabaseConnection(); Statement statement = connection.createStatement()) {
    String sqlToExecute = "SELECT * FROM persons";
    try (ResultSet resultSet = statement.execute(sqlToExecute)) {
        if (resultSet.next()) {
            System.out.println(resultSet.getString("name");
        }
    }
} catch (SQLException e) {
    System.out.println("Failed to select persons.");
}

The call to getDatabaseConnection is just made up. Replace it with a call that gets you a JDBC SQL connection or a connection from a pool.

You can use the spool command (SQL*Plus documentation, but one of many such commands SQL Developer also supports) to write results straight to disk. Each spool can change the file that's being written to, so you can have several queries writing to different files just by putting spool commands between them:

spool "\path\to\spool1.txt"

select /*csv*/ * from employees;

spool "\path\to\spool2.txt"

select /*csv*/ * from locations;

spool off;

You'd need to run this as a script (F5, or the second button on the command bar above the SQL Worksheet). You might also want to explore some of the formatting options and the set command, though some of those do not translate to SQL Developer.

Since you mentioned CSV in the title I've included a SQL Developer-specific hint that does that formatting for you.

A downside though is that SQL Developer includes the query in the spool file, which you can avoid by having the commands and queries in a script file that you then run as a script.

Cecil Curry has a great answer, however his answer only works for multiline regular expressions. Multiline regular expressions are more rarely used, but they are handy sometimes.

Here is an improvement upon his sed_inplace function that allows it to function with multiline regular expressions if asked to do so.

WARNING: In multiline mode, it will read the entire file in, and then perform the regular expression substitution, so you'll only want to use this mode on small-ish files - don't try to run this on gigabyte-sized files when running in multiline mode.

import re, shutil, tempfile

def sed_inplace(filename, pattern, repl, multiline = False):
    '''
    Perform the pure-Python equivalent of in-place `sed` substitution: e.g.,
    `sed -i -e 's/'${pattern}'/'${repl}' "${filename}"`.
    '''
    re_flags = 0
    if multiline:
        re_flags = re.M

    # For efficiency, precompile the passed regular expression.
    pattern_compiled = re.compile(pattern, re_flags)

    # For portability, NamedTemporaryFile() defaults to mode "w+b" (i.e., binary
    # writing with updating). This is usually a good thing. In this case,
    # however, binary writing imposes non-trivial encoding constraints trivially
    # resolved by switching to text writing. Let's do that.
    with tempfile.NamedTemporaryFile(mode='w', delete=False) as tmp_file:
        with open(filename) as src_file:
            if multiline:
                content = src_file.read()
                tmp_file.write(pattern_compiled.sub(repl, content))
            else:
                for line in src_file:
                    tmp_file.write(pattern_compiled.sub(repl, line))

    # Overwrite the original file with the munged temporary file in a
    # manner preserving file attributes (e.g., permissions).
    shutil.copystat(filename, tmp_file.name)
    shutil.move(tmp_file.name, filename)

from os.path import expanduser
sed_inplace('%s/.gitconfig' % expanduser("~"), r'^(\[user\]$\n[ \t]*name = ).*$(\n[ \t]*email = ).*', r'\1John Doe\[email protected]', multiline=True)

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

Try using an invisible element (or psuedoelement) to force the table-cell to expand.

td:before {
  content: '';
  display: block; 
  width: 5em;
}

JSFiddle: https://jsfiddle.net/cibulka/gf45uxr6/1/

There is a gcc extension which allows lambda templates:

// create the widgets and set the label
base::for_each(_widgets, [] <typename Key_T, typename Widget_T>
                         (boost::fusion::pair<Key_T, Widget_T*>& pair) -> void {
                             pair.second = new Widget_T();
                             pair.second->set_label_str(Key_T::label);
                          }
              );

where _widgets is a std::tuple< fusion::pair<Key_T, Widget_T>... >

Here is the steps I followed to export the .ipa

• Validate the archive
• Click on on distribute the app
• Click the distribution method
• Choose the export in the next screen (The screen shown only if the archive is validated)

If you are reading from a file then you should hear the advice given and just put it into a double.

On the other hand, if you do have, say, a string you could use boost's lexical_cast.

Here is a (very simple) example:

int Foo(std::string anInt)
{
   return lexical_cast<int>(anInt);
}

Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project check alias, in your example it is -alias alias_name, but in config you specified alias mike

If you have not tried the following command

SELECT TOP 10 * FROM big_table ORDER BY id DESC;

I see it's working when I execute the command

SELECT TOP 10 * FROM Customers ORDER BY CustomerId DESC;

in the Try it yourself command window of https://www.w3schools.com/sql/sql_func_last.asp

Yes, you may use an anchor by specifying the id attribute of an element and then linking to it with a hash.

For example (taken from the W3 specification):

You may read more about this in <A href="#section2">Section Two</A>.
...later in the document
<H2 id="section2">Section Two</H2>
...later in the document
<P>Please refer to <A href="#section2">Section Two</A> above
for more details.

You could always just up or downcase the strings first.

string title = "string":
title.ToUpper().Contains("STRING")  // returns true

Oops, just saw that last bit. A case insensitive compare would *probably* do the same anyway, and if performance is not an issue, I don't see a problem with creating uppercase copies and comparing those. I could have sworn that I once saw a case-insensitive compare once...

Actualy you don't need an internet connection to use ip address. Each computer in LAN has an internal IP address you can discover by runing

ipconfig /all

in cmd.

You can use the ip address of the server (probabily something like 192.168.0.x or 10.0.0.x) to access the website remotely.

If you found the ip and still cannot access the website, it means WAMP is not configured to respond to that name ( what did you call me? 192.168.0.3? That's not my name. I'm Localhost ) and you have to modify ....../apache/config/httpd.conf

Boost Test Library is a very good choice especially if you're already using Boost.

// TODO: Include your class to test here.
#define BOOST_TEST_MODULE MyTest
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(MyTestCase)
{
    // To simplify this example test, let's suppose we'll test 'float'.
    // Some test are stupid, but all should pass.
    float x = 9.5f;

    BOOST_CHECK(x != 0.0f);
    BOOST_CHECK_EQUAL((int)x, 9);
    BOOST_CHECK_CLOSE(x, 9.5f, 0.0001f); // Checks differ no more then 0.0001%
}

It supports:

• Automatic or manual tests registration
• Many assertions
• Automatic comparison of collections
• Various output formats (including XML)
• Fixtures / Templates...

PS: I wrote an article about it that may help you getting started: C++ Unit Testing Framework: A Boost Test Tutorial

When I go to the control panel of my webhost, open up phpMyAdmin, and click on "Show MySQL runtime information", I get:

This MySQL server has been running for 53 days, 15 hours, 28 minutes and 53 seconds. It started up on Oct 24, 2008 at 04:03 AM.

Query statistics: Since its startup, 3,444,378,344 queries have been sent to the server.

Total 3,444 M
per hour 2.68 M
per minute 44.59 k
per second 743.13

That's an average of 743 mySQL queries every single second for the past 53 days!

I don't know about you, but to me that's fast! Very fast!!

Java has evolved since this issue was first brought up. You can match all manner of unicode space characters by using the \p{Zs} group.

Thus if you wanted to replace one or more exotic spaces with a plain space you could do this:

String txt = "whatever my string is";
txt.replaceAll("\\p{Zs}+", " ")

Also worth knowing, if you've used the trim() string function you should take a look at the (relatively new) strip(), stripLeading(), and stripTrailing() functions on strings. The can help you trim off all sorts of squirrely white space characters. For more information on what what space is included, see Java's Character.isWhitespace() function.

For people that need the title set statically. This can be done in the AndroidManifest.xml

<activity
    android:name=".ActivityName"
    android:label="Title Text" >
</activity>

In my case, I had renamed the project and changed it's folder structure. I found that updating the RootNameSpace and AssemblyName in the .csproj file where the error was being thrown resolved the error. If you have modified paths of your project I'd recommend checking this as well.

<RootNamespace>Company.Product.WebAPI</RootNamespace>
<AssemblyName>Company.Product.WebAPI</AssemblyName>

Canvas text support is actually pretty good - you can control font, size, color, horizontal alignment, vertical alignment, and you can also get text metrics to get the text width in pixels. In addition, you can also use canvas transforms to rotate, stretch and even invert text.

Delegate are essentially inline Action's or Func<T>. You can declare a delegate outside the scope of a method which you are running or using a lambda expression(=>); because you run the delegate within a method, you run it on the thread which is being run for the current window/application which is the bit in bold.

Lambda example

int AddFiveToNumber(int number)
{
  var d = (int i => i + 5);
  d.Invoke(number);
}

What about @Primary?

Indicates that a bean should be given preference when multiple candidates are qualified to autowire a single-valued dependency. If exactly one 'primary' bean exists among the candidates, it will be the autowired value. This annotation is semantically equivalent to the <bean> element's primary attribute in Spring XML.

@Primary
public class HibernateDeviceDao implements DeviceDao

Or if you want your Jdbc version to be used by default:

<bean id="jdbcDeviceDao" primary="true" class="com.initech.service.dao.jdbc.JdbcDeviceDao">

@Primary is also great for integration testing when you can easily replace production bean with stubbed version by annotating it.

If you want the time as well, just go with

datetime.datetime.now().__str__()

You are human, and therefore you understand what the term "10 < x < 20" suppose to mean. The computer doesn't have this intuition, so it reads it as: "(10 < x) < 20".

For example, if x = 15, it will calculate:

(10 < x) => TRUE

"TRUE < 20" => ???

In C programming, it will be worse, since there are no True\False values. If x = 5, the calculation will be:

10 < x => 0 (the value of False)

0 < 20 => non-0 number (True)

and therefore "10 < 5 < 20" will return True! :S

http://docs.notepad-plus-plus.org/index.php/Inserting_Variable_Text

Notepad++ comes equipped with a Edit -> Column "Alt+C" Editor which can work on a rectangular selection in two different ways: Coledit.png inserting some fixed text on every line including and following the current line, at the column of the insertion point (aka caret). Initially selected text is left untouched. As the picture illustrates, a linear series of numbers can be inserted in the same manner. The starting value and increment are to be provided. Left padding with zeroes is an option, and the number may be entered in base 2, 8, 10 or 16 - this is how the computed values will be displayed too, padding being based on the largest.

The new jQuery UI version will not allow you to call UI methods on dialog which is not initialized. As a workaround, you can use the below check to see if the dialog is alive.

if (modalDialogObj.hasClass('ui-dialog-content')) {
    // call UI methods like modalDialogObj.dialog('isOpen')
} else {
    // it is not initialized yet
}

Use extended procedure xp_cmdshell to run a shell command. I used it to print output to a file:

exec xp_cmdshell 'echo "mytextoutput" >> c:\debuginfo.txt'

This creates the file debuginfo.txt if it does not exist. Then it adds the text "mytextoutput" (without quotation marks) to the file. Any call to the function will write an additional line.

You may need to enable this db-server property first (default = disabled), which I realize may not be to the liking of dba's for production environments though.

var = False
if not var: print 'learnt stuff'

In addition to specifying the path (as Jimmy mentioned) you can also force Bundler to use a local gem for your environment only by using the following configuration option:

$ bundle config local.GEM_NAME /path/to/local/git/repository

This is extremely helpful if you're developing two gems or a gem and a rails app side-by-side.

Note though, that this only works when you're already using git for your dependency, for example:

# In Gemfile
gem 'rack', :github => 'rack/rack', :branch => 'master'

# In your terminal
$ bundle config local.rack ~/Work/git/rack

As seen on the docs.

select NVL ((select 'Y' from  dual where exists
   (select  1 from sales where sales_type = 'Accessories')),'N') as rec_exists
from dual

1.Dual table will return 'Y' if record exists in sales_type table 2.Dual table will return null if no record exists in sales_type table and NVL will convert that to 'N'

If you have installed the Portable version of Chrome, or have it installed in a custom directory - the extensions won't be available in directory referenced in above answers.

Try right-clicking on Chrome's shortcut & Check the "Target" directory. From there, navigate to one directory above and you should be able to see the User Data folder and then can use the answers mentioned above

Just coerce the StatusCode to int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.

On linux, create file in /etc/default/locale with the following contents

LANG=en.utf8

and then use the source command to export this variable by running

source /etc/default/locale

The source command sets the variable permanently.

I have this issue from time-to-time and often it's because the project wasn't marked as a java project. You can change this by going to the properties for the project > Project Facets > and selecting java. You may then need to properly configure that project, but this is probably part of the problem

Use grep to match any line that has nothing between the start anchor (^) and the end anchor ($):

grep -v '^$' infile.txt > outfile.txt

If you want to remove lines with only whitespace, you can still use grep. I am using Perl regular expressions in this example, but here are other ways:

grep -P -v '^\s*$' infile.txt > outfile.txt

or, without Perl regular expressions:

grep -v '^[[:space:]]*$' infile.txt > outfile.txt

You want DateTime.Today.AddDays(1).

This might help someone like me that finds this answer when searching for solutions to how Rails handles the class loading ... I found that I had to define a module whose name matched my filename appropriately, rather than just defining a class:

In file lib/development_mail_interceptor.rb (Yes, I'm using code from a Railscast :))

module DevelopmentMailInterceptor
  class DevelopmentMailInterceptor
    def self.delivering_email(message)
      message.subject = "intercepted for: #{message.to} #{message.subject}"
      message.to = "[email protected]"
    end
  end
end

works, but it doesn't load if I hadn't put the class inside a module.

I would just do this in C++ with a text file and extract the tokens. Why? I am not a linux terminal expert like the others.
To set it up I would do this in Linux..

ffmpeg -i 2>&1 | grep "" > mytext.txt

and then run some C++ app to get the data needed. Maybe extract all the important values and reformat it for further processing by using tokens. I will just have to work on my own solution and people will just make fun of me because I am a linux newbie and I do not like scripting too much.

If you use multiple users at android, verify that the app is uninstalled everywhere.

I am not familiar with Axios, but as far as I know in javascript and ajax there is an option

withCredentials: true

This will automatically send the cookie to the client-side. As an example, this scenario is also generated with passportjs, which sets a cookie on the server

In xml there is option

android:spinnerMode="dialog"

use this for Dialog mode

This Error can also occur if you slice a negative point and pass it to the array. So check if you did

In case of fixed length of desired substring I would use substr() with negative argument for its short and readable syntax

"xxx_456".substr(-3)

For now it is compatible with common browsers and not yet strictly deprecated.

Every ComboBoxItem instance has PreviewMouseDown event. If you will subscribe your custom handler on this event on every ComboBoxItem you will have opportunity to handle every click on the dropdown list.

// Subscribe on ComboBoxItem-s events.
comboBox.Items.Cast<ComboBoxItem>().ToList().ForEach(i => i.PreviewMouseDown += ComboBoxItem_PreviewMouseDown);

private void ComboBoxItem_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
     // your handler logic...         
}

Right click on the particular element (e.g. div, table, td) and select the copy as html.

Another option is to apply a transform to the control. However, it will scale down everything including the control borders.

segmentedControl.transform = CGAffineTransformMakeScale(.6f, .6f);

Run the following query in the mysql console:

SHOW CREATE TABLE momento_distribution

Check for the line that looks something like

CONSTRAINT `momento_distribution_FK_1` FOREIGN KEY (`momento_id`) REFERENCES `momento` (`id`)

It may be different, I just put a guess as to what it could be. If you have a foreign key on both 'momento_id' & 'momento_idmember', you will get two foreign key names. The next step is to delete the foreign keys. Run the following queries:

ALTER TABLE momento_distribution DROP FOREIGN KEY momento_distribution_FK_1
ALTER TABLE momento_distribution DROP FOREIGN KEY momento_distribution_FK_2

Be sure to change the foreign key name to what you got from the CREATE TABLE query. Now you don't have any foreign keys so you can easily remove the primary key. Try the following:

ALTER TABLE  `momento_distribution` DROP PRIMARY KEY

Add the required column as follows:

ALTER TABLE  `momento_distribution` ADD  `id` INT( 11 ) NOT NULL  PRIMARY KEY AUTO_INCREMENT FIRST

This query also adds numbers so you won't need to depend on @rowid. Now you need to add the foreign key back to the earlier columns. For that, first make these indexes:

ALTER TABLE  `momento_distribution` ADD INDEX (  `momento_id` )
ALTER TABLE  `momento_distribution` ADD INDEX (  `momento_idmember` )

Now add the foreign keys. Change the Reference Table/column as you need:

ALTER TABLE  `momento_distribution` ADD FOREIGN KEY ( `momento_id`) REFERENCES  `momento` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT 
ALTER TABLE  `momento_distribution` ADD FOREIGN KEY ( `momento_idmember`) REFERENCES  `member` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT 

Hope that helps. If you get any errors, please edit the question with the structure of the reference tables & the error code(s) that you are getting.

Here is an example - accepting no parameters and returning nothing.

class CallbackTest
{
    public myCallback: {(): void;};

    public doWork(): void
    {
        //doing some work...
        this.myCallback(); //calling callback
    }
}

var test = new CallbackTest();
test.myCallback = () => alert("done");
test.doWork();

If you want to accept a parameter, you can add that too:

public myCallback: {(msg: string): void;};

And if you want to return a value, you can add that also:

public myCallback: {(msg: string): number;};

For those who may stumble across this post, you need to set

I had the same problem, I think in Chart.js 2.x.x the approach is slightly different like below.

ticks: {
    callback: function(label, index, labels) {
        return label/1000+'k';
    }
}

More in details

var options = {
    scales: {
        yAxes: [
            {
                ticks: {
                    callback: function(label, index, labels) {
                        return label/1000+'k';
                    }
                },
                scaleLabel: {
                    display: true,
                    labelString: '1k = 1000'
                }
            }
        ]
    }
}

Add this line in viewDidLoad() method.

 txtFieldName.autocapitalizationType = UITextAutocapitalizationType.words

Always try to use interface reference in Collection, this adds more flexibility.
What is the problem with the below code?

List<Map<String,List<String>>> list = new ArrayList<Map<String,List<String>>>();//This is the final list you need
Map<String, List<String>> map1 = new HashMap<String, List<String>>();//This is one instance of the  map you want to store in the above list.
List<String> arraylist1 = new ArrayList<String>();
arraylist1.add("Text1");//And so on..
map1.put("key1",arraylist1);
//And so on...
list.add(map1);//In this way you can add.

You can easily do it like the above.

While there is no denying that jQuery is a powerful tool, it is a really bad idea to use it for such a trivial operation as "get an element's attribute value".

Judging by the current accepted answer, I am going to assume that you were able to add an ID attribute to your element and use that to select it.

With that in mind, here are two pieces of code. First, the code given to you in the Accepted Answer:

$("#ID").attr("name");

And second, the Vanilla JS version of it:

document.getElementById('ID').getAttribute("name");

My results:

• jQuery: 300k operations / second
• JavaScript: 11,000k operations / second

You can test for yourself here. The "plain JavaScript" vesion is over 35 times faster than the jQuery version.

Now, that's just for one operation, over time you will have more and more stuff going on in your code. Perhaps for something particularly advanced, the optimal "pure JavaScript" solution would take one second to run. The jQuery version might take 30 seconds to a whole minute! That's huge! People aren't going to sit around for that. Even the browser will get bored and offer you the option to kill the webpage for taking too long!

As I said, jQuery is a powerful tool, but it should not be considered the answer to everything.

Use nvm to upgrade node as per the project requirement..

install nvm through homebrew.. brew update brew install nvm mkdir ~/.nvm nano ~/.bash_profile

In your .bash_profile file (you may be using an other file, according to your shell), add the following :

export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

source ~/.bash_profile echo $NVM_DIR

Here you've got a very detailed explanation of their differences

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

You can pass custom http headers with RestTemplate exchange method as below.

HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(new MediaType[] { MediaType.APPLICATION_JSON }));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("X-TP-DeviceID", "your value");

HttpEntity<RestRequest> entityReq = new HttpEntity<RestRequest>(request, headers);

RestTemplate template = new RestTemplate();

ResponseEntity<RestResponse> respEntity = template
    .exchange("RestSvcUrl", HttpMethod.POST, entityReq, RestResponse.class);

EDIT : Below is the updated code. This link has several ways of calling rest service with examples

RestTemplate restTemplate = new RestTemplate();

HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("X-TP-DeviceID", "your value");

HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);

ResponseEntity<Mall[]> respEntity = restTemplate.exchange(url, HttpMethod.POST, entity, Mall[].class);

Mall[] resp = respEntity.getBody();

Instead of doing recursion, the parts of the code with checkNextID(ID + 18) and similar could be replaced with ID+=18, and then if you remove all instances of return 0, then it should do the same thing but as a simple loop. You should then put a return 0 at the end and make your variables non-global.

the :checked pseudo-class initially applies to such elements that have the HTML4 selected and checked attributes

So, this CSS works, although styling the color is not possible in every browser:

option:checked { color: red; }

An example of this in action, hiding the currently selected item from the drop down list.

option:checked { display:none; }

<select>_x000D_
    <option>A</option>_x000D_
    <option>B</option>_x000D_
    <option>C</option>_x000D_
</select>

To style the currently selected option in the closed dropdown as well, you could try reversing the logic:

select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */

Sorry to post answer for very old thread. my answer may help other in future.

string[] TobeDistinct = {"Name","City","State"};
DataTable dtDistinct = GetDistinctRecords(DTwithDuplicate, TobeDistinct);

    //Following function will return Distinct records for Name, City and State column.
    public static DataTable GetDistinctRecords(DataTable dt, string[] Columns)
       {
           DataTable dtUniqRecords = new DataTable();
           dtUniqRecords = dt.DefaultView.ToTable(true, Columns);
           return dtUniqRecords;
       }

#include guards are the standard way of doing this. #pragma once is not, meaning that not all compilers support it.

Evidence that std::unordered_map uses a hash map in GCC stdlibc++ 6.4

This was mentioned at: https://stackoverflow.com/a/3578247/895245 but in the following answer: What data structure is inside std::map in C++? I have given further evidence of such for the GCC stdlibc++ 6.4 implementation by:

• GDB step debugging into the class
• performance characteristic analysis

Here is a preview of the performance characteristic graph described in that answer:

How to use a custom class and hash function with unordered_map

This answer nails it: C++ unordered_map using a custom class type as the key

Excerpt: equality:

struct Key
{
  std::string first;
  std::string second;
  int         third;

  bool operator==(const Key &other) const
  { return (first == other.first
            && second == other.second
            && third == other.third);
  }
};

Hash function:

namespace std {

  template <>
  struct hash<Key>
  {
    std::size_t operator()(const Key& k) const
    {
      using std::size_t;
      using std::hash;
      using std::string;

      // Compute individual hash values for first,
      // second and third and combine them using XOR
      // and bit shifting:

      return ((hash<string>()(k.first)
               ^ (hash<string>()(k.second) << 1)) >> 1)
               ^ (hash<int>()(k.third) << 1);
    }
  };

}

You will always only get an indent error if there is actually an indent error. Double check that your final line is indented the same was as the other lines -- either with spaces or with tabs. Most likely, some of the lines had spaces (or tabs) and the other line had tabs (or spaces).

Trust in the error message -- if it says something specific, assume it to be true and figure out why.

go to your cpanel and search "ini editor". You'll get "Multiphp INI Editor" There you select your wordpress directory and put upload_max_filesize = 256M post_max_size = 256M memory_limit = 256M

<?php
$url=parse_url("http://domain.com/site/gallery/1?user=12#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
?>

This is should work

You can set a callback function for the onSubmit event of the form and check the contents of each field. If it contains nothing you can then fill it with the string "empty":

<form name="my_form" action="validate.php" onsubmit="check()">
    <input type="text" name="text1" />
    <input type="submit" value="submit" />
</form>

and in your js:

function check() {
    if(document.forms["my_form"]["text1"].value == "")
        document.forms["my_form"]["text1"].value = "empty";
}

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

Arrow functions => best ES6 feature so far. They are a tremendously powerful addition to ES6, that I use constantly.

Wait, you can't use arrow function everywhere in your code, its not going to work in all cases like this where arrow functions are not usable. Without a doubt, the arrow function is a great addition it brings code simplicity.

But you can’t use an arrow function when a dynamic context is required: defining methods, create objects with constructors, get the target from this when handling events.

Arrow functions should NOT be used because:

1. They do not have this

   It uses “lexical scoping” to figure out what the value of “this” should be. In simple word lexical scoping it uses “this” from the inside the function’s body.

2. They do not have arguments

   Arrow functions don’t have an arguments object. But the same functionality can be achieved using rest parameters.

   let sum = (...args) => args.reduce((x, y) => x + y, 0) sum(3, 3, 1) // output - 7 `

3. They cannot be used with new

   Arrow functions can't be construtors because they do not have a prototype property.

When to use arrow function and when not:

1. Don't use to add function as a property in object literal because we can not access this.
2. Function expressions are best for object methods. Arrow functions are best for callbacks or methods like map, reduce, or forEach.
3. Use function declarations for functions you’d call by name (because they’re hoisted).
4. Use arrow functions for callbacks (because they tend to be terser).

By their nature, a small sample of random numbers doesn't have to be uniformly distributed. They're random, after all. I agree that if a random number generator is generating numbers that consistently appear to be grouped, then there is probably something wrong with it.

But keep in mind that randomness isn't necessarily uniform.

Edit: I added "small sample" to clarify.

This link should satisfy your curiosity.

Basically (forgetting your third example which is bad), the different between 1 and 2 is that 1 allocates space for a pointer to the array.

But in the code, you can manipulate them as pointers all the same -- only thing, you cannot reallocate the second.

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

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

DataTable conversions = query.CopyToDataTable();

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

test -e will test whether a file exists or not. The test command returns a zero value if the test succeeds or 1 otherwise.

Test can be written either as test -e or using []

[ -e "$file_name" ] && grep "poet" $file_name

Unless you actually need the output of grep you can test the return value as grep will return 1 if there are no matches and zero if there are any.

In general terms you can test if a string is non-empty using [ "string" ] which will return 0 if non-empty and 1 if empty

I've encountered problem when launching Python script from Java, script was producing too much output to standard out and everything went bad.

    <script type="text/javascript">
<!-- 
function newPage(num) {
var url=new Array();
url[0]="http://www.htmlforums.com";
url[1]="http://www.codingforums.com.";
url[2]="http://www.w3schools.com";
url[3]="http://www.webmasterworld.com";
window.location=url[num];``
}
// -->
</script>
</head>
<body>
<form action="#">
<div id="container">
<input class="butts" type="button" value="htmlforums" onclick="newPage(0)"/>
<input class="butts" type="button" value="codingforums" onclick="newPage(1)"/>
<input class="butts" type="button" value="w3schools" onclick="newPage(2)"/>
<input class="butts" type="button" value="webmasterworld" onclick="newPage(3)"/>
</div>
</form>
</body>

Here's the other way, it's simpler than the other one.

<input id="inp" type="button" value="Home Page" onclick="location.href='AdminPage.jsp';" />

It's simpler.

I changed scrollable div to be with absolute position, and everything works for me

div.sidebar {
    overflow: hidden;
    background-color: green;
    padding: 5px;
    position: fixed;
    right: 20px;
    width: 40%;
    top: 30px;
    padding: 20px;
    bottom: 30%;
}
div#fixed {
    background: #76a7dc;
    color: #fff;
    height: 30px;
}

div#scrollable {
    overflow-y: scroll;
    background: lightblue;

    position: absolute;
    top:55px; 
    left:20px;
    right:20px;
    bottom:10px;
}

DEMO with two scrollable divs

"Am i doing it right?Is there better/smarter way to achieve the output this code gave me?"

Generally speaking, yes, you're doing it right. Tkinter has no native scrollable container other than the canvas. As you can see, it's really not that difficult to set up. As your example shows, it only takes 5 or 6 lines of code to make it work -- depending on how you count lines.

"Why must i use grid method?(i tried place method, but none of the labels appear on the canvas?)"

You ask about why you must use grid. There is no requirement to use grid. Place, grid and pack can all be used. It's simply that some are more naturally suited to particular types of problems. In this case it looks like you're creating an actual grid -- rows and columns of labels -- so grid is the natural choice.

"What so special about using anchor='nw' when creating window on canvas?"

The anchor tells you what part of the window is positioned at the coordinates you give. By default, the center of the window will be placed at the coordinate. In the case of your code above, you want the upper left ("northwest") corner to be at the coordinate.

At first you need to add semi colon (;) after quantity INT NOT NULL) then remove ** from ,genre,quantity)**. to insert a value with numeric data type like int, decimal, float, etc you don't need to add single quote.

public static class JsonSerializer

    public static string Serialize<T>(this T data)
    {
        try
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
            var stream = new MemoryStream();
            serializer.WriteObject(stream, data);
            string jsonData = Encoding.UTF8.GetString(stream.ToArray(), 0, (int)stream.Length);
            stream.Close();
            return jsonData;
        }
        catch
        {
            return "";
        }
    }

    {
        try
        {
            DataContractJsonSerializer slzr = new DataContractJsonSerializer(typeof(T));
            var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonData));
            T data = (T)slzr.ReadObject(stream);
            stream.Close();
            return data;
        }
        catch
        {
            return default(T);
        }
    }
}

I just want to point out to all the people saying, "That's not the point of SecureString", that many of the people asking this question might be in an application where, for whatever reason, justified or not, they are not particularly concerned about having a temporary copy of the password sit on the heap as a GC-able string, but they have to use an API that only accepts SecureString objects. So, you have an app where you don't care whether the password is on the heap, maybe it's internal-use only and the password is only there because it's required by the underlying network protocols, and you find that that string where the password is stored cannot be used to e.g. set up a remote PowerShell Runspace -- but there is no easy, straight-forward one-liner to create that SecureString that you need. It's a minor inconvenience -- but probably worth it to ensure that the applications that really do need SecureString don't tempt the authors to use System.String or System.Char[] intermediaries. :-)

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

data.Select(x=>x.Name).Distinct().Select(x => new SelectListItem { Text = x });

By default git diff is used to show the changes which is not added to the list of git updated files. But if you want to show the changes which is added or stagged then you need to provide extra options that will let git know that you are interested in stagged or added files diff .

$ git diff          # Default Use
$ git diff --cached # Can be used to show difference after adding the files 
$ git diff --staged # Same as 'git diff --cached' mostly used with latest version of git 

Example

$ git diff 
diff --git a/x/y/z.js  b/x/y/z.js index 98fc22b..0359d84 100644
--- a/x/y/z.js 
+++ b/x/y/z.js @@ -43,7 +43,7 @@ var a = function (tooltip) {

         else
             res = 2;

$ git add x/y/z.js
$ git diff
$

Once you added the files , you can't use default of 'git diff' .You have to do like this:-

$ git diff --cached
diff --git a/x/y/z.js  b/x/y/z.js index 98fc22b..0359d84 100644

They are not different from the point of view of JVM. Immutable objects don't have methods that can change the instance variables. And the instance variables are private; therefore you can't change it after you create it. A famous example would be String. You don't have methods like setString, or setCharAt. And s1 = s1 + "w" will create a new string, with the original one abandoned. That's my understanding.

To fetch only one distinct record from duplicate column of two rows you can use "rowid" column which is maintained by oracle itself as Primary key,so first try

"select rowid,RequestID,CreatedDate,HistoryStatus  from temptable;"

and then you can fetch second row only by it's value of 'rowid' column by using in SELECT statement.

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

Use apaches startup debug tool from command:

httpd.exe -e warn

1. press Win+R
2. type cmd and press enter
3. goto directory which contains your apache httpd.exe file. for example if your wamp is installed in e:\wamp type cd /d e:\wamp\bin\apache\ApacheX.X.X\bin in cmd and press enter.
4. type httpd.exe -e warn (or httpd.exe -e debug for more details) to see error message about problem which is prohibiting apache to start.

This worked for me:

list.stream().distinct().collect(Collectors.toList());

You need to implement equals, of course

What you need is xml comments - basically, they follow this syntax (as vaguely described by Solmead):

C#

///<summary>
///This is a description of my function.
///</summary>
string myFunction() {
     return "blah";
}

VB

'''<summary>
'''This is a description of my function.
'''</summary>
Function myFunction() As String
    Return "blah"
End Function

In Netbeans please delete current you create the jar file and on the project explore of Netbeans please clean and build 2 or 3 times and right the project folder in project explore and build the jar file.

This will replace all ? with ':

UPDATE dbo.authors    
SET    city = replace(city, '?', '''')
WHERE city LIKE '%?%'

If you need to update more than one column, you can either change city each time you execute to a different column name, or list the columns like so:

UPDATE dbo.authors    
SET    city = replace(city, '?', '''')
      ,columnA = replace(columnA, '?', '''')
WHERE city LIKE '%?%'
OR columnA LIKE '%?%'

Make sure you have selected the correct version of Visual Studio. This is trickier than it seems because Visual Studio 2015 is actually Visual Studio 14, and similarly Visual Studio 2012 is Visual Studio 11. I had incorrectly selected Visual Studio 15 which is actually Visual Studio 2017, when I had 2015 installed.

use

pattern.compile("\"");
String s= p.toString()+"yourcontent"+p.toString();

will give result as yourcontent as is

Here are step by step instructions for you to find out:

1. If you're using any version of Windows, do Ctrl - Shift - Esc of open Task Manager.
2. Open GitHub, and look into Task Manager.
3. There should be something like this:
4. Right click the row called GitHub, and select "Open file location".
5. A window should pop up, showing you where the file is.

There you go!

You can do this with any application, not just GitHub.

Combine JS & CSS :

button{
  /* 1st state */
}

button:hover{
  /* hover state */
}

button:active{
  /* click state */
}

button.active{
  /* after click state */
}


jQuery('button').click(function(){
   jQuery(this).toggleClass('active');
});

#!/bin/bash
tot=$(wc -c /proc/$$/fd/255 | awk '/ /{print $1}')
now() {
echo $(( 100* ($(awk '/^pos:/{print $2}' < /proc/$$/fdinfo/255)-166) / (tot-166) )) "%"
}
now;
now;
now;
now;
now;
now;
now;
now;
now;

output:

0 %
12 %
25 %
37 %
50 %
62 %
75 %
87 %
100 %

note: if instead of 255 you put 1 you will monitor the standard in...with 2 the standard out (but you must modify the source to set "tot" to the projected output file size)

A JavaScript accordion does the trick.

This fiddle by W3Schools makes a simple task even more simple using nothing but javascript, which i partially reproduce below.

<head>
<style>
button.accordion {
    background-color: #eee;
    color: #444;
    font-size: 15px;
    cursor: pointer;
}

button.accordion.active, button.accordion:hover {
    background-color: #ddd; 
}

div.panel {
    padding: 0 18px;
    display: none;
    background-color: white;
}

div.panel.show {
    display: block;
}
</style>
</head><body>
<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
    this.classList.toggle("active");
    this.nextElementSibling.classList.toggle("show");
  }
}
</script>
...
<button class="accordion">Section 1</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
</div>
...
<button class="accordion">Table</button>
<div class="panel">
  <p><table name="detail_table">...</table></p>
</div>
...
<button class="accordion"><table name="button_table">...</table></button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
  <table name="detail_table">...</table>
  <img src=...></img>
</div>
...
</body></html>

if using php, don't forget to convert " to '. You can also use tables of data inside the button and it will still work.

If you need only one upper case and special character then this should work:

@"^(?=.{8,}$)(?=[^A-Z]*[A-Z][^A-Z]*$)\w*\W\w*$"

A quick note: Assume.assumeTrue(condition) ignores rest of the steps but passes the test. To fail the test, use org.junit.Assert.fail() inside the conditional statement. Works same like Assume.assumeTrue() but fails the test.
