The various overloads of Runtime.getRuntime().exec(...) take either an array of strings or a single string. The single-string overloads of exec() will tokenise the string into an array of arguments, before passing the string array onto one of the exec() overloads that takes a string array. The ProcessBuilder constructors, on the other hand, only take a varargs array of strings or a List of strings, where each string in the array or list is assumed to be an individual argument. Either way, the arguments obtained are then joined up into a string that is passed to the OS to execute.

So, for example, on Windows,

Runtime.getRuntime().exec("C:\DoStuff.exe -arg1 -arg2");

will run a DoStuff.exe program with the two given arguments. In this case, the command-line gets tokenised and put back together. However,

ProcessBuilder b = new ProcessBuilder("C:\DoStuff.exe -arg1 -arg2");

will fail, unless there happens to be a program whose name is DoStuff.exe -arg1 -arg2 in C:\. This is because there's no tokenisation: the command to run is assumed to have already been tokenised. Instead, you should use

ProcessBuilder b = new ProcessBuilder("C:\DoStuff.exe", "-arg1", "-arg2");

or alternatively

List<String> params = java.util.Arrays.asList("C:\DoStuff.exe", "-arg1", "-arg2");
ProcessBuilder b = new ProcessBuilder(params);

I too can use only Java 6. I used @EvgeniyDorofeev's thread scanner implementation. In my code, after a process finishes, I have to immediately execute two other processes that each compare the redirected output (a diff-based unit test to ensure stdout and stderr are the same as the blessed ones).

The scanner threads don't finish soon enough, even if I waitFor() the process to complete. To make the code work correctly, I have to make sure the threads are joined after the process finishes.

public static int runRedirect (String[] args, String stdout_redirect_to, String stderr_redirect_to) throws IOException, InterruptedException {
    ProcessBuilder b = new ProcessBuilder().command(args);
    Process p = b.start();
    Thread ot = null;
    PrintStream out = null;
    if (stdout_redirect_to != null) {
        out = new PrintStream(new BufferedOutputStream(new FileOutputStream(stdout_redirect_to)));
        ot = inheritIO(p.getInputStream(), out);
        ot.start();
    }
    Thread et = null;
    PrintStream err = null;
    if (stderr_redirect_to != null) {
        err = new PrintStream(new BufferedOutputStream(new FileOutputStream(stderr_redirect_to)));
        et = inheritIO(p.getErrorStream(), err);
        et.start();
    }
    p.waitFor();    // ensure the process finishes before proceeding
    if (ot != null)
        ot.join();  // ensure the thread finishes before proceeding
    if (et != null)
        et.join();  // ensure the thread finishes before proceeding
    int rc = p.exitValue();
    return rc;
}

private static Thread inheritIO (final InputStream src, final PrintStream dest) {
    return new Thread(new Runnable() {
        public void run() {
            Scanner sc = new Scanner(src);
            while (sc.hasNextLine())
                dest.println(sc.nextLine());
            dest.flush();
        }
    });
}

Using JNA, supporting old and new JVM to get process id

public static long getProcessId(Process p){
    long pid = -1;
    try {
      pid = p.pid();
    } catch (NoSuchMethodError e) {
        try
        {
            //for windows
            if (p.getClass().getName().equals("java.lang.Win32Process") || p.getClass().getName().equals("java.lang.ProcessImpl")) {
                Field f = p.getClass().getDeclaredField("handle");
                f.setAccessible(true);              
                long handl = f.getLong(p);
                Kernel32 kernel = Kernel32.INSTANCE;
                WinNT.HANDLE hand = new WinNT.HANDLE();
                hand.setPointer(Pointer.createConstant(handl));
                pid = kernel.GetProcessId(hand);
                f.setAccessible(false);
            }
            //for unix based operating systems
            else if (p.getClass().getName().equals("java.lang.UNIXProcess")) 
            {
                Field f = p.getClass().getDeclaredField("pid");
                f.setAccessible(true);
                pid = f.getLong(p);
                f.setAccessible(false);
            }
        }
        catch(Exception ex)
        {
            pid = -1;
        }
    }        
    return pid;
}

The Runtime.getRuntime().exec() approach is quite troublesome, as you'll find out shortly.

Take a look at the Apache Commons Exec project. It abstracts you way of a lot of the common problems associated with using the Runtime.getRuntime().exec() and ProcessBuilder API.

It's as simple as:

String line = "myCommand.exe";
CommandLine commandLine = CommandLine.parse(line);
DefaultExecutor executor = new DefaultExecutor();
executor.setExitValue(1);
int exitValue = executor.execute(commandLine);

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.

Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)

**

ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
 int returnVal = process.exitValue();
}

The answers on here are specific to using the custom UI Editor. I spent some time creating the interface without that wonderful program, so I am documenting the solution here to help anyone else decide if they need that custom UI editor or not.

I came across the following microsoft help webpage - https://msdn.microsoft.com/en-us/library/office/ff861787.aspx. This shows how to set up the interface manually, but I had some trouble when pointing to my custom add-in code.

To get the buttons to work with your custom macros, setup the macro in your .xlam subs to be called as described in this SO answer - Calling an excel macro from the ribbon. Basically, you'll need to add that "control As IRibbonControl" paramter to any module pointed from your ribbon xml. Also, your ribbon xml should have the onAction="myaddin!mymodule.mysub" syntax to properly call any modules loaded by the add in.

Using those instructions I was able to create an excel add in (.xlam file) that has a custom tab loaded when my VBA gets loaded into Excel along with the add in. The buttons execute code from the add in and the custom tab uninstalls when I remove the add in.

• go to dosbox installation directory (on my machine that is C:\Program Files (x86)\DOSBox-0.74 ) as you see the version number is part of the installation directory name.

• run "DOSBox 0.74 Options.bat"

• the script starts notepad with configuration file: here change

  windowresolution=1600x800

  output=ddraw

(the resolution can't be changed if output=surface - that's the default).

• safe configuration file changes.

An alternative approach would be to extract features (keypoints) using the scale-invariant feature transform (SIFT) or Speeded Up Robust Features (SURF).

You can find a nice OpenCV code example in Java, C++, and Python on this page: Features2D + Homography to find a known object

Both algorithms are invariant to scaling and rotation. Since they work with features, you can also handle occlusion (as long as enough keypoints are visible).

Image source: tutorial example

The processing takes a few hundred ms for SIFT, SURF is bit faster, but it not suitable for real-time applications. ORB uses FAST which is weaker regarding rotation invariance.

The original papers

• SURF: Speeded Up Robust Features
• Distinctive Image Features from Scale-Invariant Keypoints
• ORB: an efficient alternative to SIFT or SURF

I made my own custom imageview with pinch to zoom. There is no limits/borders on Chirag Ravals code, so user can drag the image off the screen. This will fix it.

This is how you can use it in your activity:

CustomImageVIew mImageView = (CustomImageVIew)findViewById(R.id.customImageVIew1);
mImage.setBitmap(your bitmap);

And layout:

<your.package.name.CustomImageVIew
        android:id="@+id/customImageVIew1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginBottom="15dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:layout_marginTop="15dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" 
        android:scaleType="matrix"/> // important

overflow: auto; or overflow: hidden; should do it I think.

From the definition of height:

Applies to: all elements but non-replaced inline elements, table columns, and column groups

An a element is, by default an inline element (and it is non-replaced).

You need to change the display (directly with the display property or indirectly, e.g. with float).

You can use the DATE(Year;Month;Day) to make operations on date:

Examples:

=DATE(2013;3;8 + 30) give the result...  7 april 2013 !
=DATE(2013;3 + 15; 8) give the result... 8 june 2014 !

It's very surprising but it works...

An "em" is a typographical unit of width, the width of a wide-ish letter like "m" pronounced "em". Similarly there is an "en". Similarly "en-dash" and "em-dash" for – and —

-Tim Bray

You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).

Your code could be like:

const myArray = [  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

const myOrderedArray = _.sortBy(myArray, o => o.name)

If you don't mind using functions:

var constant = function(val) {
   return function() {
        return val;
    }
}

This approach gives you functions instead of regular variables, but it guarantees^* that no one can alter the value once it's set.

a = constant(10);

a(); // 10

b = constant(20);

b(); // 20

I personally find this rather pleasant, specially after having gotten used to this pattern from knockout observables.

^{_{*Unless someone redefined the function constant before you called it}}

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

no it doesnt. break is for loops, not ifs.

nested if statements are just terrible. If you can avoid them, avoid them. Can you rewrite your code to be something like

if (c1 && c2) {
    //sequence 1
} else if (c3 && c2) {
   // sequence 3
}

that way you don't need any control logic to 'break out' of the loop.

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

The problem is that chrome.tabs.getSelected is asynchronous. This code below will generally not work as expected. The value of 'tablink' will still be undefined when it is written to the console because getSelected has not yet invoked the callback that resets the value:

var tablink;
chrome.tabs.getSelected(null,function(tab) {
    tablink = tab.url;
});
console.log(tablink);

The solution is to wrap the code where you will be using the value in a function and have that invoked by getSelected. In this way you are guaranteed to always have a value set, because your code will have to wait for the value to be provided before it is executed.

Try something like:

chrome.tabs.getSelected(null, function(tab) {
    myFunction(tab.url);
});

function myFunction(tablink) {
  // do stuff here
  console.log(tablink);
}

Another way in addition to the ones provided here for ES6

module.exports = class TEST{
    constructor(size) {
        this.map = new MAp();
        this.size = size;

    }

    get(key) {
        return this.map.get(key);
    }

    length() {
        return this.map.size;
    }    

}

and include the same as

var TEST= require('./TEST');
var test = new TEST(1);

For me perfectly fork this code.

$('#dom_object_id').on('change paste keyup', function(){
    console.log($("#dom_object_id").val().length)
});

Key event for .on() function is "paste" to get changes dynamically

As previously mentioned - in case of a project, Makefile or otherwise, this is a project configuration issue, where you'll likely need to specify other flags too.

But what about one-off programs, where you would normally just write g++ file.cpp && ./a.out?

Well, I would much like to have some #pragma to turn in on at source level, or maybe a default extension - say .cxx or .C11 or whatever, trigger it by default. But as of today, there is no such feature.

But, as you probably are working in a manual environment (i.e. shell), you can just have an alias in you .bashrc (or whatever):

alias g++11="g++ -std=c++0x"

or, for newer G++ (and when you want to feel "real C++11")

alias g++11="g++ -std=c++11"

You can even alias to g++ itself, if you hate C++03 that much ;)

What is the datatype for column1 in your Hive table? Please note that if your column is STRING it won't be having a NULL value even though your external file does not have any data for that column.

git reset --hard origin/{branchName}

It will delete all untracked files.

The color for your buttons comes from the btn-x classes (e.g., btn-primary, btn-success), so if you want to manually change the colors by writing your own custom css rules, you'll need to change:

/*This is modifying the btn-primary colors but you could create your own .btn-something class as well*/
.btn-primary {
    color: #fff;
    background-color: #0495c9;
    border-color: #357ebd; /*set the color you want here*/
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
    color: #fff;
    background-color: #00b3db;
    border-color: #285e8e; /*set the color you want here*/
}

I was getting the same error when creating a view.

Imagine a select query that executes without issue:

select id
from products

Attempting to create a view from the same query would produce an error:

create view app.foobar as
select id
from products

Msg 207, Level 16, State 1, Procedure foobar, Line 2
Invalid column name 'id'.

For me it turned out to be a scoping issue; note the view is being created in a different schema. Specifying the schema of the products table solved the issue. Ie.. using dbo.products instead of just products.

Spot on!!

You can use below query to remove all the tables from database

EXEC sp_MSforeachtable @command1 = "DROP TABLE ?"

Happy coding !

is_uploaded_file() is great to use, specially for checking whether it is an uploaded file or a local file (for security purposes).

However, if you want to check whether the user uploaded a file, use $_FILES['file']['error'] == UPLOAD_ERR_OK.

See the PHP manual on file upload error messages. If you just want to check for no file, use UPLOAD_ERR_NO_FILE.

I’ve looked on Coursera and other resources such as blogs and textbooks, but I find them either not comprehensive enough or at the other end of the spectrum, too dense with prerequisite computer science terminologies.

The dude in the video have a bunch of lectures on data structures. Don’t mind the silly drawings, or the slight accent at all. You need to understand not just which data structure to select, but some other points to consider when people think about data structures:

I also posted notes on github if you are interested.

If you're in Windows & using MSVC, the MSDN library has sample code that does this.

And here's the code from that link:

#include <windows.h>
#include <tchar.h> 
#include <stdio.h>
#include <strsafe.h>

void ErrorHandler(LPTSTR lpszFunction);

int _tmain(int argc, TCHAR *argv[])
{
   WIN32_FIND_DATA ffd;
   LARGE_INTEGER filesize;
   TCHAR szDir[MAX_PATH];
   size_t length_of_arg;
   HANDLE hFind = INVALID_HANDLE_VALUE;
   DWORD dwError=0;

   // If the directory is not specified as a command-line argument,
   // print usage.

   if(argc != 2)
   {
      _tprintf(TEXT("\nUsage: %s <directory name>\n"), argv[0]);
      return (-1);
   }

   // Check that the input path plus 2 is not longer than MAX_PATH.

   StringCchLength(argv[1], MAX_PATH, &length_of_arg);

   if (length_of_arg > (MAX_PATH - 2))
   {
      _tprintf(TEXT("\nDirectory path is too long.\n"));
      return (-1);
   }

   _tprintf(TEXT("\nTarget directory is %s\n\n"), argv[1]);

   // Prepare string for use with FindFile functions.  First, copy the
   // string to a buffer, then append '\*' to the directory name.

   StringCchCopy(szDir, MAX_PATH, argv[1]);
   StringCchCat(szDir, MAX_PATH, TEXT("\\*"));

   // Find the first file in the directory.

   hFind = FindFirstFile(szDir, &ffd);

   if (INVALID_HANDLE_VALUE == hFind) 
   {
      ErrorHandler(TEXT("FindFirstFile"));
      return dwError;
   } 

   // List all the files in the directory with some info about them.

   do
   {
      if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
      {
         _tprintf(TEXT("  %s   <DIR>\n"), ffd.cFileName);
      }
      else
      {
         filesize.LowPart = ffd.nFileSizeLow;
         filesize.HighPart = ffd.nFileSizeHigh;
         _tprintf(TEXT("  %s   %ld bytes\n"), ffd.cFileName, filesize.QuadPart);
      }
   }
   while (FindNextFile(hFind, &ffd) != 0);

   dwError = GetLastError();
   if (dwError != ERROR_NO_MORE_FILES) 
   {
      ErrorHandler(TEXT("FindFirstFile"));
   }

   FindClose(hFind);
   return dwError;
}


void ErrorHandler(LPTSTR lpszFunction) 
{ 
    // Retrieve the system error message for the last-error code

    LPVOID lpMsgBuf;
    LPVOID lpDisplayBuf;
    DWORD dw = GetLastError(); 

    FormatMessage(
        FORMAT_MESSAGE_ALLOCATE_BUFFER | 
        FORMAT_MESSAGE_FROM_SYSTEM |
        FORMAT_MESSAGE_IGNORE_INSERTS,
        NULL,
        dw,
        MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
        (LPTSTR) &lpMsgBuf,
        0, NULL );

    // Display the error message and exit the process

    lpDisplayBuf = (LPVOID)LocalAlloc(LMEM_ZEROINIT, 
        (lstrlen((LPCTSTR)lpMsgBuf)+lstrlen((LPCTSTR)lpszFunction)+40)*sizeof(TCHAR)); 
    StringCchPrintf((LPTSTR)lpDisplayBuf, 
        LocalSize(lpDisplayBuf) / sizeof(TCHAR),
        TEXT("%s failed with error %d: %s"), 
        lpszFunction, dw, lpMsgBuf); 
    MessageBox(NULL, (LPCTSTR)lpDisplayBuf, TEXT("Error"), MB_OK); 

    LocalFree(lpMsgBuf);
    LocalFree(lpDisplayBuf);
}

To get cell column name as well as cell value :

List<JObject> dataList = new List<JObject>();

for (int i = 0; i < dataTable.Rows.Count; i++)
{
    JObject eachRowObj = new JObject();

    for (int j = 0; j < dataTable.Columns.Count; j++)
    {
        string key = Convert.ToString(dataTable.Columns[j]);
        string value = Convert.ToString(dataTable.Rows[i].ItemArray[j]);

        eachRowObj.Add(key, value);

    }

    dataList.Add(eachRowObj);

}

That's one of the few legitimate jobs for cat:

openssl verify -verbose -CAfile <(cat Intermediate.pem RootCert.pem) UserCert.pem

Update:

As Greg Smethells points out in the comments, this command implicitly trusts Intermediate.pem. I recommend reading the first part of the post Greg references (the second part is specifically about pyOpenSSL and not relevant to this question).

In case the post goes away I'll quote the important paragraphs:

Unfortunately, an "intermediate" cert that is actually a root / self-signed will be treated as a trusted CA when using the recommended command given above:

$ openssl verify -CAfile <(cat geotrust_global_ca.pem rogue_ca.pem) fake_sometechcompany_from_rogue_ca.com.pem fake_sometechcompany_from_rogue_ca.com.pem: OK

It seems openssl will stop verifying the chain as soon as a root certificate is encountered, which may also be Intermediate.pem if it is self-signed. In that case RootCert.pem is not considered. So make sure that Intermediate.pem is coming from a trusted source before relying on the command above.

That's an odd approach with isUserAnswer. Are you really going to send all three choices back to the server where it will loop through each one checking for isUserAnswer == true? If so, you can try this:

http://jsfiddle.net/hgxjv/4/

HTML:

<input type="radio" name="response" value="true" ng-click="setChoiceForQuestion(question1, choice)"/>

JavaScript:

$scope.setChoiceForQuestion = function (q, c) {
    angular.forEach(q.choices, function (c) {
        c.isUserAnswer = false;
    });

    c.isUserAnswer = true;
};

Alternatively, I'd recommend changing your tack:

http://jsfiddle.net/hgxjv/5/

<input type="radio" name="response" value="{{choice.id}}" ng-model="question1.userChoiceId"/>

That way you can just send {{question1.userChoiceId}} back to the server.

there are many ways ,

two best ways for this are

$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
echo json_encode($arr);
//ouputs as
{"a":1,"b":2,"c":3,"d":4,"e":5}


$b = array ('m' => 'monkey', 'foo' => 'bar', 'x' => array ('x', 'y', 'z'));
$results = print_r($b, true); // $results now contains output from print_r

Use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

new webpack.DefinePlugin(definitions)

Example:

plugins: [
  new webpack.DefinePlugin({
    PRODUCTION: JSON.stringify(true)
  })
  //...
]

Usage:

console.log(`Environment is in production: ${PRODUCTION}`);

The above example using sort is close, but in the case of strings simply use SearchString:

files := []string{"Test.conf", "util.go", "Makefile", "misc.go", "main.go"}
target := "Makefile"
sort.Strings(files)
i := sort.SearchStrings(files, target)
if i < len(files) && files[i] == target {
    fmt.Printf("found \"%s\" at files[%d]\n", files[i], i)
}

https://golang.org/pkg/sort/#SearchStrings

In Visual Basic, it should be:

Public Enum Question
    Role = 2
    ProjectFunding = 3
    TotalEmployee = 4
    NumberOfServers = 5
    TopBusinessConcern = 6
End Enum

Private value As Integer = CInt(Question.Role)

1. You can use apachectl -V or apachectl -v. Both of them will return the Apache version information!

You can center a box both vertically and horizontally, using the following technique :

The outher container :

• should have display: table;

The inner container :

• should have display: table-cell;
• should have vertical-align: middle;
• should have text-align: center;

The content box :

• should have display: inline-block;

If you use this technique, just add your table (along with any other content you want to go with it) to the content box.

Postgres allows:

UPDATE dummy
SET customer=subquery.customer,
    address=subquery.address,
    partn=subquery.partn
FROM (SELECT address_id, customer, address, partn
      FROM  /* big hairy SQL */ ...) AS subquery
WHERE dummy.address_id=subquery.address_id;

This syntax is not standard SQL, but it is much more convenient for this type of query than standard SQL. I believe Oracle (at least) accepts something similar.

You can do trickery by using exec() to invoke something that can do HTTP requests, like wget, but you must direct all output from the program to somewhere, like a file or /dev/null, otherwise the PHP process will wait for that output.

If you want to separate the process from the apache thread entirely, try something like (I'm not sure about this, but I hope you get the idea):

exec('bash -c "wget -O (url goes here) > /dev/null 2>&1 &"');

It's not a nice business, and you'll probably want something like a cron job invoking a heartbeat script which polls an actual database event queue to do real asynchronous events.

From a maintainability standpoint, it's much simpler to manage one item in one file, than it is to manage multiple items in possibly multiple files.

Separating your styling will help make your life much easier, especially when job duties are distributed amongst different individuals. Reusability and portability will save you plenty of time down the road.

When using an inline style, that will override any external properties that are set.

The CSS table model is based on the HTML table model http://www.w3.org/TR/CSS21/tables.html

A table is divided into ROWS, and each row contains one or more cells. Cells are children of ROWS, they are NEVER children of columns.

"display: table-column" does NOT provide a mechanism for making columnar layouts (e.g. newspaper pages with multiple columns, where content can flow from one column to the next).

Rather, "table-column" ONLY sets attributes that apply to corresponding cells within the rows of a table. E.g. "The background color of the first cell in each row is green" can be described.

The table itself is always structured the same way it is in HTML.

In HTML (observe that "td"s are inside "tr"s, NOT inside "col"s):

<table ..>
  <col .. />
  <col .. />
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
</table>

Corresponding HTML using CSS table properties (Note that the "column" divs do not contain any contents -- the standard does not allow for contents directly in columns):

.mytable {_x000D_
  display: table;_x000D_
}_x000D_
.myrow {_x000D_
  display: table-row;_x000D_
}_x000D_
.mycell {_x000D_
  display: table-cell;_x000D_
}_x000D_
.column1 {_x000D_
  display: table-column;_x000D_
  background-color: green;_x000D_
}_x000D_
.column2 {_x000D_
  display: table-column;_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 1</div>_x000D_
    <div class="mycell">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 2</div>_x000D_
    <div class="mycell">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

OPTIONAL: both "rows" and "columns" can be styled by assigning multiple classes to each row and cell as follows. This approach gives maximum flexibility in specifying various sets of cells, or individual cells, to be styled:

//Useful css declarations, depending on what you want to affect, include:_x000D_
_x000D_
/* all cells (that have "class=mycell") */_x000D_
.mycell {_x000D_
}_x000D_
_x000D_
/* class row1, wherever it is used */_x000D_
.row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 (if you've put "class=mycell" on each cell) */_x000D_
.row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 */_x000D_
.row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows */_x000D_
.cell1 {_x000D_
}_x000D_
_x000D_
/* row1 inside class mytable (so can have different tables with different styles) */_x000D_
.mytable .row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 of a mytable */_x000D_
.mytable .row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 of a mytable */_x000D_
.mytable .row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows of a mytable */_x000D_
.mytable .cell1 {_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow row1">_x000D_
    <div class="mycell cell1">contents of first cell in row 1</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow row2">_x000D_
    <div class="mycell cell1">contents of first cell in row 2</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

In today's flexible designs, which use <div> for multiple purposes, it is wise to put some class on each div, to help refer to it. Here, what used to be <tr> in HTML became class myrow, and <td> became class mycell. This convention is what makes the above CSS selectors useful.

PERFORMANCE NOTE: putting class names on each cell, and using the above multi-class selectors, is better performance than using selectors ending with *, such as .row1 * or even .row1 > *. The reason is that selectors are matched last first, so when matching elements are being sought, .row1 * first does *, which matches all elements, and then checks all the ancestors of each element, to find if any ancestor has class row1. This might be slow in a complex document on a slow device. .row1 > * is better, because only the immediate parent is examined. But it is much better still to immediately eliminate most elements, via .row1 .cell1. (.row1 > .cell1 is an even tighter spec, but it is the first step of the search that makes the biggest difference, so it usually isn't worth the clutter, and the extra thought process as to whether it will always be a direct child, of adding the child selector >.)

The key point to take away re performance is that the last item in a selector should be as specific as possible, and should never be *.

I found a way around this after 3-4 hours of googling. I have added the following

<startup selegacyv2runtimeactivationpolicy="true">
  <supportedruntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client" />
</startup>

If this doesn't solve your problem then--> In the Project References Right Click on DLL where you getting error --> Select Properties--> Check the Run-time Version --> If it is v2.0.50727 then we know the problem. The Problem is :- you are having 2.0 Version of respective DLL. Solution is:- You can delete the respective DLL from the Project references and then download the latest version of DLL's from the corresponding website and add the reference of the latest version DLL reference then it will work.

Generally, the "specialized structure" actually IS a sensible current state of an object, with its own methods.

class Some3SpaceThing(object):
  def __init__(self,x):
    self.g(x)
  def g(self,x):
    self.y0 = x + 1
    self.y1 = x * 3
    self.y2 = y0 ** y3

r = Some3SpaceThing( x )
r.y0
r.y1
r.y2

I like to find names for anonymous structures where possible. Meaningful names make things more clear.

-- Update --

As of January 9th, 2015. the solution is now implemented in Rails 5 ActiveRecord's secure token implementation.

-- Rails 4 & 3 --

Just for future reference, creating safe random token and ensuring it's uniqueness for the model (when using Ruby 1.9 and ActiveRecord):

class ModelName < ActiveRecord::Base

  before_create :generate_token

  protected

  def generate_token
    self.token = loop do
      random_token = SecureRandom.urlsafe_base64(nil, false)
      break random_token unless ModelName.exists?(token: random_token)
    end
  end

end

Edit:

@kain suggested, and I agreed, to replace begin...end..while with loop do...break unless...end in this answer because previous implementation might get removed in the future.

Edit 2:

With Rails 4 and concerns, I would recommend moving this to concern.

# app/models/model_name.rb
class ModelName < ActiveRecord::Base
  include Tokenable
end

# app/models/concerns/tokenable.rb
module Tokenable
  extend ActiveSupport::Concern

  included do
    before_create :generate_token
  end

  protected

  def generate_token
    self.token = loop do
      random_token = SecureRandom.urlsafe_base64(nil, false)
      break random_token unless self.class.exists?(token: random_token)
    end
  end
end

In eclipse,

• Install Jaspersoft Studio for eclipse.
• Right click the .jrxml file and select Open with JasperReports Book Editor
• Open the Design tab for the .jrxml file.
• On top of the window you can see the Compile Report icon.

Go to

Settings -> Android SDK -> SDK Tools ->

and make sure you install Google Play Services

 int[][] myNums = { {1, 2, 3, 4, 5, 6, 7}, {5, 6, 7, 8, 9, 10, 11} };
 for (int x = 0; x < myNums.length; ++x) {
    for(int y = 0; y < myNums[i].length; ++y) {
       System.out.print(myNums[x][y]);
    }
 }

Output

1 2 3 4 5 6 7 5 6 7 8 9 10 11

Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>", other links associated with Facebook turns into "on.fb.me/*****". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.

By default, Log4j logs to standard output and that means you should be able to see log messages on your Eclipse's console view. To log to a file you need to use a FileAppender explicitly by defining it in a log4j.properties file in your classpath.

Create the following log4j.properties file in your classpath. This allows you to log your message to both a file as well as your console.

log4j.rootLogger=debug, stdout, file

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=example.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%p %t %c - %m%n

Note: The above creates an example.log in your current working directory (i.e. Eclipse's project directory) so that the same log4j.properties could work with different projects without overwriting each other's logs.

From the CLI the best way is to use grep like:

php -i | grep libxml

You can try this:

select
  count(distinct tag) as tag_count,
  count(distinct (case when entryId > 0 then tag end)) as positive_tag_count
from
  your_table_name;

The first count(distinct...) is easy. The second one, looks somewhat complex, is actually the same as the first one, except that you use case...when clause. In the case...when clause, you filter only positive values. Zeros or negative values would be evaluated as null and won't be included in count.

One thing to note here is that this can be done by reading the table once. When it seems that you have to read the same table twice or more, it can actually be done by reading once, in most of the time. As a result, it will finish the task a lot faster with less I/O.

It is very simple. For example : in you JS controller use this:

$scope.inputngmodel.$valid = false;

or

$scope.inputngmodel.$invalid = true;

or

$scope.formname.inputngmodel.$valid = false;

or

$scope.formname.inputngmodel.$invalid = true;

All works for me for different requirement. Hit up if this solve your problem.

Well, you could argue with the object oriented aspect, the prepared statements, the fact that it becomes a standard, etc. But I know that most of the time, convincing somebody works better with a killer feature. So there it is:

A really nice thing with PDO is you can fetch the data, injecting it automatically in an object. If you don't want to use an ORM (cause it's a just a quick script) but you do like object mapping, it's REALLY cool :

class Student {

    public $id;
    public $first_name;
    public $last_name

    public function getFullName() {
        return $this->first_name.' '.$this->last_name
    }
}

try 
{
    $dbh = new PDO("mysql:host=$hostname;dbname=school", $username, $password)

    $stmt = $dbh->query("SELECT * FROM students");

    /* MAGIC HAPPENS HERE */

    $stmt->setFetchMode(PDO::FETCH_INTO, new Student);


    foreach($stmt as $student)
    {
        echo $student->getFullName().'<br />';
    } 

    $dbh = null;
}
catch(PDOException $e)
{
    echo $e->getMessage();
}

An other approach is to use splice.

The splice() method changes the contents of an array by removing or replacing existing elements and/or adding new elements in place.

N.B : In case you're working with reactive frameworks, it will update the "view", your array "knowing" you've updated it.

Answer :

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

let foundIndex = items.findIndex(element => element.id === item.id)
items.splice(foundIndex, 1, item)

And in case you want to only change a value of an item, you can use find function :

// Retrieve item and assign ref to updatedItem
let updatedItem = items.find((element) => { return element.id === item.id })

// Modify object property
updatedItem.aProp = ds.aProp

Write a function lensort to sort a list of strings based on length.

def lensort(a):
    n = len(a)
    for i in range(n):
        for j in range(i+1,n):
            if len(a[i]) > len(a[j]):
                temp = a[i]
                a[i] = a[j]
                a[j] = temp
    return a
print lensort(["hello","bye","good"])

As noted in other answers, you should avoid the pseudo-typedef antipattern. However, typedefs are still useful even if that is not the way to achieve them. You want to distinguish between different abstract types that have the same Java representation. You don't want to mix up strings that are passwords with those that are street addresses, or integers that represent an offset with those with those that represent an absolute value.

The Checker Framework enables you to define a typedef in a backward-compatible way. I works even for primitive classes such as int and final classes such as String. It has no run-time overhead and does not break equality tests.

Section Type aliases and typedefs in the Checker Framework manual describes several ways to create typedefs, depending on your needs.

You shouldn't be passing anything in to getCountry(). Remove Locale.getDefault():

String locale = context.getResources().getConfiguration().locale.getCountry();

Java array reflection is for cases where you don't have an instance of the Class available to do "instanceof" on. For example, if you're writing some sort of injection framework, that injects values into a new instance of a class, such as JPA does, then you need to use the isArray() functionality.

I blogged about this earlier in December. http://blog.adamsbros.org/2010/12/08/java-array-reflection/

In my case, this was caused by a custom parent component setting the rendering layer type to "Software":

setLayerType(View.LAYER_TYPE_SOFTWARE, null);

Removing this line of did the trick. Or course you need to evaluate why this is there in the first place. In my case it was to support Honeycomb, which is well behind the current minimum SDK for my project.

  CONSTRAINT user_pkey PRIMARY KEY (id)
)

Joel's answer is good for reasons you might have to use C, though there are a few others:

• You must meet industry guidelines, which are easier to prove and test for in C
• You have tools to work with C, but not C++ (think not just about the compiler, but all the support tools, coverage, analysis, etc)
• Your target developers are C gurus
• You're writing drivers, kernels, or other low-level code
• You know the C++ compiler isn't good at optimizing the kind of code you need to write
• Your app not only doesn't lend itself to be object-oriented but would be harder to write in that form

In some cases, though, you might want to use C rather than C++:

• You want the performance of assembler without the trouble of coding in assembler (C++ is, in theory, capable of 'perfect' performance, but the compilers aren't as good at seeing optimizations a good C programmer will see)

• The software you're writing is trivial, or nearly so - whip out the tiny C compiler, write a few lines of code, compile and you're all set - no need to open a huge editor with helpers, no need to write practically empty and useless classes, deal with namespaces, etc. You can do nearly the same thing with a C++ compiler and simply use the C subset, but the C++ compiler is slower, even for tiny programs.

• You need extreme performance or small code size and know the C++ compiler will actually make it harder to accomplish due to the size and performance of the libraries.

You contend that you could just use the C subset and compile with a C++ compiler, but you'll find that if you do that you'll get slightly different results depending on the compiler.

Regardless, if you're doing that, you're using C. Is your question really "Why don't C programmers use C++ compilers?" If it is, then you either don't understand the language differences, or you don't understand the compiler theory.

I like this question because this is an area where there's continuous innovation and there's always a need to have a light server especially when talking about embedded servers in small(er) devices. I think answers fall into two broad groups.

1. Thin-server: server-up static content with minimal processing, context or session processing.
2. Small-server: ostensibly a has many httpD-like server qualities with as small a footprint as you can get away with.

While I might consider HTTP libraries like: Jetty, Apache Http Components, Netty and others to be more like a raw HTTP processing facilities. The labelling is very subjective, and depends on the kinds of thing you've been call-on to deliver for small-sites. I make this distinction in the spirit of the question, particularly the remark about...

• "...without writing code to manually parse HTTP requests and manually format HTTP responses..."

These raw tools let you do that (as described in other answers). They don't really lend themselves to a ready-set-go style of making a light, embedded or mini-server. A mini-server is something that can give you similar functionality to a full-function web server (like say, Tomcat) without bells and whistles, low volume, good performance 99% of the time. A thin-server seems closer to the original phrasing just a bit more than raw perhaps with a limited subset functionality, enough to make you look good 90% of the time. My idea of raw would be makes me look good 75% - 89% of the time without extra design and coding. I think if/when you reach the level of WAR files, we've left the "small" for bonsi servers that looks like everything a big server does smaller.

Thin-server options

• Grizzly
• UniRest (multiple-languages)
• NanoHTTPD (just one file)

Mini-server options:

• Spark Java ... Good things are possible with lots of helper constructs like Filters, Templates, etc.
• MadVoc ... aims to be bonsai and could well be such ;-)

Among the other things to consider, I'd include authentication, validation, internationalisation, using something like FreeMaker or other template tool to render page output. Otherwise managing HTML editing and parameterisation is likely to make working with HTTP look like noughts-n-crosses. Naturally it all depends on how flexible you need to be. If it's a menu-driven FAX machine it can be very simple. The more interactions, the 'thicker' your framework needs to be. Good question, good luck!

I had some troubles with the code suggested by yboussard. The inner j loop didn't work. Here is the modified code that I use with success.

function reloadScripts(toRefreshList/* list of js to be refresh */, key /* change this key every time you want force a refresh */) {
    var scripts = document.getElementsByTagName('script');
    for(var i = 0; i < scripts.length; i++) {
        var aScript = scripts[i];
        for(var j = 0; j < toRefreshList.length; j++) {
            var toRefresh = toRefreshList[j];
            if(aScript.src && (aScript.src.indexOf(toRefresh) > -1)) {
                new_src = aScript.src.replace(toRefresh, toRefresh + '?k=' + key);
                // console.log('Force refresh on cached script files. From: ' + aScript.src + ' to ' + new_src)
                aScript.src = new_src;
            }
        }
    }
}

Here's what I initially did, which does work, however it seems rather long-winded and ugly (global static anything is never good)

1: App.xaml.cs

public partial class App : Application
{
    // create a new global custom WPF Command
    public static readonly RoutedUICommand LoggedIn = new RoutedUICommand();
}

2: LoginForm.xaml

// bind the global command to a local eventhandler
<CommandBinding Command="client:App.LoggedIn" Executed="OnLoggedIn" />

3: LoginForm.xaml.cs

// implement the local eventhandler in codebehind
private void OnLoggedIn( object sender, ExecutedRoutedEventArgs e )
{
    DialogResult = true;
    Close();
}

4: LoginFormViewModel.cs

// fire the global command from the viewmodel
private void OnRemoteServerReturnedSuccess()
{
    App.LoggedIn.Execute(this, null);
}

I later on then removed all this code, and just had the LoginFormViewModel call the Close method on it's view. It ended up being much nicer and easier to follow. IMHO the point of patterns is to give people an easier way to understand what your app is doing, and in this case, MVVM was making it far harder to understand than if I hadn't used it, and was now an anti-pattern.

While you were looking for a VBA solution, this was my top result on google when looking for a formula solution, so I'll add this for anyone who came here for that like I did:

Excel formula to return the number from a column letter (From @A. Klomp's comment above), where cell A1 holds your column letter(s):

=column(indirect(A1&"1"))

As the indirect function is volatile, it recalculates whenever any cell is changed, so if you have a lot of these it could slow down your workbook. Consider another solution, such as the 'code' function, which gives you the number for an ASCII character, starting with 'A' at 65. Note that to do this you would need to check how many digits are in the column name, and alter the result depending on 'A', 'BB', or 'CCC'.

Excel formula to return the column letter from a number (From this previous question How to convert a column number (eg. 127) into an excel column (eg. AA), answered by @Ian), where A1 holds your column number:

=substitute(address(1,A1,4),"1","")

Note that both of these methods work regardless of how many letters are in the column name.

Hope this helps someone else.

In English:

It's a List of some type that extends the class HasWord, including HasWord

In general the ? in generics means any class. And the extends SomeClass specifies that that object must extend SomeClass (or be that class).

Well, Process Explorer has a suspend option. You can right click a process in the process column and select suspend. Once you are ready to resume it again right click and this time select resume. Process Explorer can be obtained from here:

http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

Simply put these codes at top of your PHP/index file:

error_reporting(E_ALL); // Error/Exception engine, always use E_ALL

ini_set('ignore_repeated_errors', TRUE); // always use TRUE

ini_set('display_errors', FALSE); // Error/Exception display, use FALSE only in production environment or real server. Use TRUE in development environment

ini_set('log_errors', TRUE); // Error/Exception file logging engine.
ini_set('error_log', 'your/path/to/errors.log'); // Logging file path

If you're able to control the xml file, try adding a bit more information to the beginning of the file:

<?xml version="1.0" encoding="UTF-16" standalone="no"?>

Looks to me as MySQL 3.6 gives the following error while MySQL 3.7 no longer errors out. I am yet to find anything in the documentation regarding this fix.

You should use Adaptive hashing like http://en.wikipedia.org/wiki/Bcrypt for securing passwords

For sqlite, it is possible to set a callable to connection.row_factory and change the format of query results to python dictionary object. See the documentation. Here is an example:

import sqlite3, json

def dict_factory(cursor, row):
    d = {}
    for idx, col in enumerate(cursor.description):
        # col[0] is the column name
        d[col[0]] = row[idx]
    return d

def get_data_to_json():
    conn = sqlite3.connect("database.db")
    conn.row_factory = dict_factory
    c = conn.cursor()
    c.execute("SELECT * FROM table")
    rst = c.fetchall() # rst is a list of dict
    return jsonify(rst)

You can accomplish this by using the <datalist> tag in HTML5.

<input type="text" name="product" list="productName"/>
    <datalist id="productName">
        <option value="Pen">Pen</option>
        <option value="Pencil">Pencil</option>
        <option value="Paper">Paper</option>
    </datalist>

If you double click on the input text in the browser a list with the defined option will appear.

You can always pass host as a parameter to the URL helper:

listing_url(listing, host: request.host)

Note, that starting from PostgreSQL 8.4 you can get all information about sequences used in the database via:

SELECT * FROM information_schema.sequences;

Since I'm using a higher version of PostgreSQL (9.1), and was searching for same answer high and low, I added this answer for posterity's sake and for future searchers.

setTimout on 0 is also very useful in the pattern of setting up a deferred promise, which you want to return right away:

myObject.prototype.myMethodDeferred = function() {
    var deferredObject = $.Deferred();
    var that = this;  // Because setTimeout won't work right with this
    setTimeout(function() { 
        return myMethodActualWork.call(that, deferredObject);
    }, 0);
    return deferredObject.promise();
}

There is no difference between both statements above. AS is just a more explicit way of mentioning the alias

I've fixed the issue using this solution.If you are running the application in USB device then close all the virtual device like : genymotion / virtual machine .

The /Date(ms + timezone)/ is a ASP.NET syntax for JSON dates. You might want to use a library like momentjs for parsing such dates. It would come in handy if you need to manipulate or print the dates any time later.

My case was dodgy typing

myApp.factory('Notify',funtion(){

function has a 'c' !

Don't use print ..., if you don't want spaces. Use string concatenation or formatting.

Concatenation:

print 'Value is "' + str(value) + '"'

Formatting:

print 'Value is "{}"'.format(value)

The latter is far more flexible, see the str.format() method documentation and the Formatting String Syntax section.

You'll also come across the older % formatting style:

print 'Value is "%d"' % value
print 'Value is "%d", but math.pi is %.2f' % (value, math.pi)

but this isn't as flexible as the newer str.format() method.

Use the following extensions and just pass the action like:

_frmx.PerformSafely(() => _frmx.Show());
_frmx.PerformSafely(() => _frmx.Location = new Point(x,y));

Extension class:

public static class CrossThreadExtensions
{
    public static void PerformSafely(this Control target, Action action)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action);
        }
        else
        {
            action();
        }
    }

    public static void PerformSafely<T1>(this Control target, Action<T1> action,T1 parameter)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, parameter);
        }
        else
        {
            action(parameter);
        }
    }

    public static void PerformSafely<T1,T2>(this Control target, Action<T1,T2> action, T1 p1,T2 p2)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, p1,p2);
        }
        else
        {
            action(p1,p2);
        }
    }
}

The most correct to copy object is use Object.create:

Object.create(Object.getPrototypeOf(obj), Object.getOwnPropertyDescriptors(obj));

Such a notation will make identically the same object with right prototype and hidden properties.

I found the way to do it. You need to convert Data to NSData:

let characterSet = CharacterSet(charactersIn: "<>")
let nsdataStr = NSData.init(data: deviceToken)
let deviceStr = nsdataStr.description.trimmingCharacters(in: characterSet).replacingOccurrences(of: " ", with: "")
print(deviceStr)

I believe you need to .f file as a parameter, not as a command-single-string. same with the "--domain "+i, which i would split in two elements of the list. Assuming that:

• you have the path set for FORTRAN executable,
• the ~/ is indeed the correct way for the FORTRAN executable

I would change this line:

subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])

to

subprocess.Popen(["FORTRAN", "~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain", i])

If that doesn't work, you should do a os.path.exists() for the .f file, and check that you can launch the FORTRAN executable without any path, and set the path or system path variable accordingly

[EDIT 6-Mar-2017]

As the exception, detailed in the original post, is a python exception from subprocess; it is likely that the WinError 2 is because it cannot find FORTRAN

I highly suggest that you specify full path for your executable:

for i in input:
    exe = r'c:\somedir\fortrandir\fortran.exe'
    fortran_script = r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f'
    subprocess.Popen([exe, fortran_script, "--domain", i])

if you need to convert the forward-slashes to backward-slashes, as suggested in one of the comments, you can do this:

for i in input:
    exe = os.path.normcase(r'c:\somedir\fortrandir\fortran.exe')
    fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[EDIT 7-Mar-2017]

The following line is incorrect:

exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe'

I am not sure why you have ~/ as a prefix for every path, don't do that.

for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe'
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[2nd EDIT 7-Mar-2017]

I do not know this FORTRAN or ftn95.exe, does it need a shell to function properly?, in which case you need to launch as follows:

subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)

You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess command.

<script type="text/javascript">
$(document).ready(function(){    
    //Check if the current URL contains '#'
    if(document.URL.indexOf("#")==-1){
        // Set the URL to whatever it was plus "#".
        url = document.URL+"#";
        location = "#";

        //Reload the page
        location.reload(true);
    }
});
</script>

Due to the if condition the page will reload only once.I faced this problem too and when I search ,I found this nice solution. This works for me fine.

The MOST IMPORTANT THING I didn't understand for quite awhile is that the request MUST contain "callback=JSON_CALLBACK", because AngularJS modifies the request url, substituting a unique identifier for "JSON_CALLBACK". The server response must use the value of the 'callback' parameter instead of hard coding "JSON_CALLBACK":

JSON_CALLBACK(json_response);  // wrong!

Since I was writing my own PHP server script, I thought I knew what function name it wanted and didn't need to pass "callback=JSON_CALLBACK" in the request. Big mistake!

AngularJS replaces "JSON_CALLBACK" in the request with a unique function name (like "callback=angular.callbacks._0"), and the server response must return that value:

angular.callbacks._0(json_response);

Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly mscorlib

Yes, this technically can go wrong when you execute code on .NET 4.0 instead of .NET 4.5. The attribute was moved from System.Core.dll to mscorlib.dll in .NET 4.5. While that sounds like a rather nasty breaking change in a framework version that is supposed to be 100% compatible, a [TypeForwardedTo] attribute is supposed to make this difference unobservable.

As Murphy would have it, every well intended change like this has at least one failure mode that nobody thought of. This appears to go wrong when ILMerge was used to merge several assemblies into one and that tool was used incorrectly. A good feedback article that describes this breakage is here. It links to a blog post that describes the mistake. It is rather a long article, but if I interpret it correctly then the wrong ILMerge command line option causes this problem:

  /targetplatform:"v4,c:\windows\Microsoft.NET\Framework\v4.0.30319"

Which is incorrect. When you install 4.5 on the machine that builds the program then the assemblies in that directory are updated from 4.0 to 4.5 and are no longer suitable to target 4.0. Those assemblies really shouldn't be there anymore but were kept for compat reasons. The proper reference assemblies are the 4.0 reference assemblies, stored elsewhere:

  /targetplatform:"v4,C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0"

So possible workarounds are to fall back to 4.0 on the build machine, install .NET 4.5 on the target machine and the real fix, to rebuild the project from the provided source code, fixing the ILMerge command.

Do note that this failure mode isn't exclusive to ILMerge, it is just a very common case. Any other scenario where these 4.5 assemblies are used as reference assemblies in a project that targets 4.0 is liable to fail the same way. Judging from other questions, another common failure mode is in build servers that were setup without using a valid VS license. And overlooking that the multi-targeting packs are a free download.

Using the reference assemblies in the c:\program files (x86) subdirectory is a rock hard requirement. Starting at .NET 4.0, already important to avoid accidentally taking a dependency on a class or method that was added in the 4.01, 4.02 and 4.03 releases. But absolutely essential now that 4.5 is released.

If the answers that involve tables or setting line-height don't work for you, you can experiment with wrapping the p element in a div and style its positioning relative to the height of the parent div.

.parent-div{_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.text-div{_x000D_
  position: relative;_x000D_
  top: 50%;_x000D_
  transform: translateY(-50%);_x000D_
}_x000D_
_x000D_
p.event_desc{_x000D_
  font: bold 12px "Helvetica Neue", Helvetica, Arial, sans-serif;_x000D_
  color: white;_x000D_
  text-align: center;_x000D_
}

<div class="parent-div">_x000D_
  <div class="text-div">_x000D_
   <p class="event_desc">_x000D_
    MY TEXT_x000D_
   </p>_x000D_
  </div>_x000D_
</div>

I created an open-source tool for making this easy. Enter the strings you want and you'll instantly get the mailto:

JPA will use all properties of the class, unless you specifically mark them with @Transient:

@Transient
private String agencyName;

The @Column annotation is purely optional, and is there to let you override the auto-generated column name. Furthermore, the length attribute of @Column is only used when auto-generating table definitions, it has no effect on the runtime.

In Entity Framework 6.1+ you can use this attribute on your model:

[Index(IsUnique=true)]

You can find it in this namespace:

using System.ComponentModel.DataAnnotations.Schema;

If your model field is a string, make sure it is not set to nvarchar(MAX) in SQL Server or you will see this error with Entity Framework Code First:

Column 'x' in table 'dbo.y' is of a type that is invalid for use as a key column in an index.

The reason is because of this:

SQL Server retains the 900-byte limit for the maximum total size of all index key columns."

(from: http://msdn.microsoft.com/en-us/library/ms191241.aspx )

You can solve this by setting a maximum string length on your model:

[StringLength(450)]

Your model will look like this now in EF CF 6.1+:

public class User
{
   public int UserId{get;set;}
   [StringLength(450)]
   [Index(IsUnique=true)]
   public string UserName{get;set;}
}

Update:

if you use Fluent:

  public class UserMap : EntityTypeConfiguration<User>
  {
    public UserMap()
    {
      // ....
      Property(x => x.Name).IsRequired().HasMaxLength(450).HasColumnAnnotation("Index", new IndexAnnotation(new[] { new IndexAttribute("Index") { IsUnique = true } }));
    }
  }

and use in your modelBuilder:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
  // ...
  modelBuilder.Configurations.Add(new UserMap());
  // ...
}

2021 Answer

Instead of using document.getElementById() you can now use document.querySelector() for different cases

more info from another StackOverflow answer:

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

EXAMPLE:

document.querySelector('input[name="myInput"]').value = 'Whatever you want!';

or

let myInput = document.querySelector('input[name="myInput"]');
myInput.value = 'Whatever you want!';

Test:

document.querySelector('input[name="myInput"]').value = 'Whatever you want!';

<input type="text" name="myInput" id="myInput" placeholder="Your text">

Or you can simply update without using join like this:

Update t1 set  t1.Description = t2.Description from @tbl2 t2,tbl1 t1
where t1.ID= t2.ID

rm !(textfile.txt|backup.tar.gz|script.php|database.sql|info.txt)

The extglob (Extended Pattern Matching) needs to be enabled in BASH (if it's not enabled):

shopt -s extglob

For all the python3 and pip3 users out there:

curl https://bootstrap.pypa.io/get-pip.py | sudo python3

and then assume you want to install pandas

pip3 install pandas --user

#include <stdbool.h>

For someone like me here to copy and paste.

WITH UpdateList_view AS (
  SELECT TOP 1  * from TX_Master_PCBA 
  WHERE SERIAL_NO IN ('0500030309') 
  ORDER BY TIMESTAMP2 DESC 
)

update UpdateList_view 
set TIMESTAMP2 = '2013-12-12 15:40:31.593'

How about:

import pandas as pd
#List with all words
words=[]

#Code for adding words
words.append('test')


#When Input equals blank:
pd.Series(words).nunique()

It returns how many unique values are in a list

Better example is here

 try {
   myDB = this.openOrCreateDatabase("DatabaseName", MODE_PRIVATE, null);

   /* Create a Table in the Database. */
   myDB.execSQL("CREATE TABLE IF NOT EXISTS "
     + TableName
     + " (Field1 VARCHAR, Field2 INT(3));");

   /* Insert data to a Table*/
   myDB.execSQL("INSERT INTO "
     + TableName
     + " (Field1, Field2)"
     + " VALUES ('Saranga', 22);");

   /*retrieve data from database */
   Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);

   int Column1 = c.getColumnIndex("Field1");
   int Column2 = c.getColumnIndex("Field2");

   // Check if our result was valid.
   c.moveToFirst();
   if (c != null) {
    // Loop through all Results
    do {
     String Name = c.getString(Column1);
     int Age = c.getInt(Column2);
     Data =Data +Name+"/"+Age+"\n";
    }while(c.moveToNext());
   }

1 - Make a selector file "show_password_selector.xml"

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/pwd_hide"
          android:state_selected="true"/>
    <item android:drawable="@drawable/pwd_show"
          android:state_selected="false" />
 </selector>

2 - Aet "show_password_selector" file into imageview.

<ImageView
    android:id="@+id/iv_pwd"
    android:layout_width="@dimen/_35sdp"
    android:layout_height="@dimen/_25sdp"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="@dimen/_15sdp"
    android:src="@drawable/show_password_selector" />

3 - Put below code in java file.

iv_new_pwd.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (iv_new_pwd.isSelected()) {
            iv_new_pwd.setSelected(false);
            Log.d("mytag", "in case 1");
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT);
        } else {
            Log.d("mytag", "in case 1");
            iv_new_pwd.setSelected(true);
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        }
    }
});

Any kind of data your computer stores and processes is in its most basic representation a row of bits. The way those bits are interpreted is done through data types. Data types can be primitive or complex. Primitive data types are - for instance - int or double. They have a specific length and a specific way of being interpreted. In the case of an integer, usually the first bit is used for the sign, the others are used for the value.

Complex data types can be combinations of primitive and other complex data types and are called "Class" in Java.

You can define the complex data type PeopleName consisting of two Strings called first and last name. Each String in Java is another complex data type. Strings in return are (probably) implemented using the primitive data type char for which Java knows how many bits they take to store and how to interpret them.

When you create an instance of a data type, you get an object and your computers reserves some memory for it and remembers its location and the name of that instance. An instance of PeopleName in memory will take up the space of the two String variables plus a bit more for bookkeeping. An integer takes up 32 bits in Java.

Complex data types can have methods assigned to them. Methods can perform actions on their arguments or on the instance of the data type you call this method from. If you have two instances of PeopleName called p1 and p2 and you call a method p1.getFirstName(), it usually returns the first name of the first person but not the second person's.

 /**
 * Usage "foo baz".insertInside(4, 0, "bar ") ==> "foo bar baz"
 */
String.prototype.insertInside = function(start, delCount, newSubStr) {
    return this.slice(0, start) + newSubStr + this.slice(start + Math.abs(delCount));
};


 $('textarea').bind("keydown keypress", function (event) {
   var val = $(this).val();
   var indexOf = $(this).prop('selectionStart');
   if(event.which === 13) {
       val = val.insertInside(indexOf, 0,  "<br>\n");
       $(this).val(val);
       $(this).focus();
    }
})

For jquery-ui-dragable with jquery-ui-touch-punch I fixed it similar to Iván Rodríguez, but with one more event override for touchmove:

jQuery.event.special.touchstart = {
    setup: function( _, ns, handle ) {
        this.addEventListener('touchstart', handle, { passive: !ns.includes('noPreventDefault') });
    }
};
jQuery.event.special.touchmove = {
    setup: function( _, ns, handle ) {
        this.addEventListener('touchmove', handle, { passive: !ns.includes('noPreventDefault') });
    }
};

Your attempt at an athlete class seems to be dealing with a group of athletes, which is a design fault.

Define a class to represent a single athlete, with fields that represent the athlete's attributes:

public class Athlete {
    private final String name;
    private final String country;
    private List<Performance> performances = new ArrayList<Performance>();
    // other fields as required

    public Athlete (String name, String country) {
        this.name = name;
        this.country = country;
    }
    // getters omitted

    public List<Performance> getPerformances() {
        return performances;
    }

    public Performance perform(Dive dive) {
        // not sure what your intention is here, but something like this:
        Performance p = new Performance(dive, this);
        // add new performance to list
        performances.add(p);
        return p;
    }
}

Then your main method would use ti like this:

public class Assignment1 {
    public static void main(String[] args) {
        String[] name = {"Art", "Dan", "Jen"};
        String[] country = {"Canada", "Germant", "USA"};
        Dive[] dive = new Dive[]{new Dive("somersault"), new Dive("foo"), new Dive("bar")};
        for (int i = 0; i < name.length; i++) {
            Athlete athlete = new Athlete(name[i], country[i]);
            Performance performance = athlete.perform(dive[i]);   
            // do something with athlete and/or performance
        }
    }
}

It would make sense for CSS to have a way to simply add an additional style (in the head section of your page, for example, which would override the linked style sheet) such as this:

<head>
<style>
#elementId select {
    /* turn all styles off (no way to do this) */
}
</style>
</head>

and turn off all previously applied styles, but there is no way to do this. You will have to override the height attribute and set it to a new value in the head section of your pages.

<head>
<style>
#elementId select {
    height:1.5em;
}
</style>
</head>

TL;DR

Either change the collation of one (or both) of the strings so that they match, or else add a COLLATE clause to your expression.

1. What is this "collation" stuff anyway?

   As documented under Character Sets and Collations in General:

   A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. Let's make the distinction clear with an example of an imaginary character set.

   Suppose that we have an alphabet with four letters: “A”, “B”, “a”, “b”. We give each letter a number: “A” = 0, “B” = 1, “a” = 2, “b” = 3. The letter “A” is a symbol, the number 0 is the encoding for “A”, and the combination of all four letters and their encodings is a character set.

   Suppose that we want to compare two string values, “A” and “B”. The simplest way to do this is to look at the encodings: 0 for “A” and 1 for “B”. Because 0 is less than 1, we say “A” is less than “B”. What we've just done is apply a collation to our character set. The collation is a set of rules (only one rule in this case): “compare the encodings.” We call this simplest of all possible collations a binary collation.

   But what if we want to say that the lowercase and uppercase letters are equivalent? Then we would have at least two rules: (1) treat the lowercase letters “a” and “b” as equivalent to “A” and “B”; (2) then compare the encodings. We call this a case-insensitive collation. It is a little more complex than a binary collation.

   In real life, most character sets have many characters: not just “A” and “B” but whole alphabets, sometimes multiple alphabets or eastern writing systems with thousands of characters, along with many special symbols and punctuation marks. Also in real life, most collations have many rules, not just for whether to distinguish lettercase, but also for whether to distinguish accents (an “accent” is a mark attached to a character as in German “Ö”), and for multiple-character mappings (such as the rule that “Ö” = “OE” in one of the two German collations).

   Further examples are given under Examples of the Effect of Collation.

2. Okay, but how does MySQL decide which collation to use for a given expression?

   As documented under Collation of Expressions:

   In the great majority of statements, it is obvious what collation MySQL uses to resolve a comparison operation. For example, in the following cases, it should be clear that the collation is the collation of column charset_name:

   SELECT x FROM T ORDER BY x;
   SELECT x FROM T WHERE x = x;
   SELECT DISTINCT x FROM T;
   

   However, with multiple operands, there can be ambiguity. For example:

   SELECT x FROM T WHERE x = 'Y';
   

   Should the comparison use the collation of the column x, or of the string literal 'Y'? Both x and 'Y' have collations, so which collation takes precedence?

   Standard SQL resolves such questions using what used to be called “coercibility” rules.

   [ deletia ]

   MySQL uses coercibility values with the following rules to resolve ambiguities:

   • Use the collation with the lowest coercibility value.

   • If both sides have the same coercibility, then:

     • If both sides are Unicode, or both sides are not Unicode, it is an error.

     • If one of the sides has a Unicode character set, and another side has a non-Unicode character set, the side with Unicode character set wins, and automatic character set conversion is applied to the non-Unicode side. For example, the following statement does not return an error:

       SELECT CONCAT(utf8_column, latin1_column) FROM t1;
       

       It returns a result that has a character set of utf8 and the same collation as utf8_column. Values of latin1_column are automatically converted to utf8 before concatenating.

     • For an operation with operands from the same character set but that mix a _bin collation and a _ci or _cs collation, the _bin collation is used. This is similar to how operations that mix nonbinary and binary strings evaluate the operands as binary strings, except that it is for collations rather than data types.

3. So what is an "illegal mix of collations"?

   An "illegal mix of collations" occurs when an expression compares two strings of different collations but of equal coercibility and the coercibility rules cannot help to resolve the conflict. It is the situation described under the third bullet-point in the above quotation.

   The particular error given in the question, Illegal mix of collations (latin1_general_cs,IMPLICIT) and (latin1_general_ci,IMPLICIT) for operation '=', tells us that there was an equality comparison between two non-Unicode strings of equal coercibility. It furthermore tells us that the collations were not given explicitly in the statement but rather were implied from the strings' sources (such as column metadata).

4. That's all very well, but how does one resolve such errors?

   As the manual extracts quoted above suggest, this problem can be resolved in a number of ways, of which two are sensible and to be recommended:

   • Change the collation of one (or both) of the strings so that they match and there is no longer any ambiguity.

     How this can be done depends upon from where the string has come: Literal expressions take the collation specified in the collation_connection system variable; values from tables take the collation specified in their column metadata.

   • Force one string to not be coercible.

     I omitted the following quote from the above:

     MySQL assigns coercibility values as follows:

     • An explicit COLLATE clause has a coercibility of 0. (Not coercible at all.)

     • The concatenation of two strings with different collations has a coercibility of 1.

     • The collation of a column or a stored routine parameter or local variable has a coercibility of 2.

     • A “system constant” (the string returned by functions such as USER() or VERSION()) has a coercibility of 3.

     • The collation of a literal has a coercibility of 4.

     • NULL or an expression that is derived from NULL has a coercibility of 5.

     Thus simply adding a COLLATE clause to one of the strings used in the comparison will force use of that collation.

   Whilst the others would be terribly bad practice if they were deployed merely to resolve this error:

   • Force one (or both) of the strings to have some other coercibility value so that one takes precedence.

     Use of CONCAT() or CONCAT_WS() would result in a string with a coercibility of 1; and (if in a stored routine) use of parameters/local variables would result in strings with a coercibility of 2.

   • Change the encodings of one (or both) of the strings so that one is Unicode and the other is not.

     This could be done via transcoding with CONVERT(expr USING transcoding_name); or via changing the underlying character set of the data (e.g. modifying the column, changing character_set_connection for literal values, or sending them from the client in a different encoding and changing character_set_client / adding a character set introducer). Note that changing encoding will lead to other problems if some desired characters cannot be encoded in the new character set.

   • Change the encodings of one (or both) of the strings so that they are both the same and change one string to use the relevant _bin collation.

     Methods for changing encodings and collations have been detailed above. This approach would be of little use if one actually needs to apply more advanced collation rules than are offered by the _bin collation.

You can make master point at 1258f0d0aae this way:

git checkout master
git reset --hard 1258f0d0aae

But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.

Also, the git reset --hard command will throw away any uncommitted changes (i.e. those just in your working tree or the index).

You can also force an update to a branch with:

git branch -f master 1258f0d0aae

... but git won't let you do that if you're on master at the time.

I had the same confusion. After some tinkering based on many of the answers above, I can finally see the differences. In my humble opinion, the distinction is best demonstrated with a flex container that satisfies the following two conditions:

1. The flex container itself has a height constraint (e.g., min-height: 60rem) and thus can become too tall for its content
2. The child items enclosed in the container have uneven heights

Condition 1 helps me understand what content means relative to its parent container. When the content is flush with the container, we will not be able to see any positioning effects coming from align-content. It is only when we have extra space along the cross axis, we start to see its effect: It aligns the content relative to the boundaries of the parent container.

Condition 2 helps me visualize the effects of align-items: it aligns items relative to each other.

Here is a code example. Raw materials come from Wes Bos' CSS Grid tutorial (21. Flexbox vs. CSS Grid)

• Example HTML:

  <div class="flex-container">
    <div class="item">Short</div>
    <div class="item">Longerrrrrrrrrrrrrr</div>
    <div class="item"></div>
    <div class="item" id="tall">This is Many Words</div>
    <div class="item">Lorem, ipsum.</div>
    <div class="item">10</div>
    <div class="item">Snickers</div>
    <div class="item">Wes Is Cool</div>
    <div class="item">Short</div>
  </div>

• Example CSS:

.flex-container {
  display: flex;
  /*dictates a min-height*/
  min-height: 60rem;
  flex-flow: row wrap;
  border: 5px solid white;
  justify-content: center;
  align-items: center;
  align-content: flex-start;
 }

#tall {
  /*intentionally made tall*/
  min-height: 30rem;
}

.item {
  margin: 10px;
  max-height: 10rem;
}

Example 1: Let's narrow the viewport so that the content is flush with the container. This is when align-content: flex-start; has no effects since the entire content block is tightly fit inside the container (no extra room for repositioning!)

Also, note the 2nd row--see how the items are center aligned among themselves.

Example 2: As we widen the viewport, we no longer have enough content to fill the entire container. Now we start to see the effects of align-content: flex-start;--it aligns the content relative to the top edge of the container.

These examples are based on flexbox, but the same principles are applicable to CSS grid. Hope this helps :)

Here is a part of code I use to direct my server.js file to angular dist folder, which was created after npm build

// Create link to Angular build directory
var distDir = __dirname + "/dist/";
app.use(express.static(distDir));

I fixed it by changing "/dist/" to "./dist/"

You can also access fields using a simillar manner:

var obj=new MyObject();
FieldInfo fi = obj.GetType().
  GetField("Name", BindingFlags.NonPublic | BindingFlags.Instance);
fi.SetValue(obj,value)

With reflection everything can be an open book:) In my example we are binding to a private instance level field.

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

When you need to accept a function as argument which takes no arguments and returns no result (void), in my opinion it is still best to have something like

  public interface Thunk { void apply(); }

somewhere in your code. In my functional programming courses the word 'thunk' was used to describe such functions. Why it isn't in java.util.function is beyond my comprehension.

In other cases I find that even when java.util.function does have something that matches the signature I want - it still doesn't always feel right when the naming of the interface doesn't match the use of the function in my code. I guess it's a similar point that is made elsewhere here regarding 'Runnable' - which is a term associated with the Thread class - so while it may have he signature I need, it is still likely to confuse the reader.

You can try this one it is short

SystemClock.sleep(7000);

WARNING: Never, ever, do this on a UI thread.

Use this to sleep eg. background thread.

Full solution for your problem will be: This is available API 1

findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View button) {
                button.setBackgroundResource(R.drawable.avatar_dead);
                final long changeTime = 1000L;
                button.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        button.setBackgroundResource(R.drawable.avatar_small);
                    }
                }, changeTime);
            }
        });

Without creating tmp Handler. Also this solution is better than @tronman because we do not retain view by Handler. Also we don't have problem with Handler created at bad thread ;)

Documentation

public static void sleep (long ms)

Added in API level 1

Waits a given number of milliseconds (of uptimeMillis) before returning. Similar to sleep(long), but does not throw InterruptedException; interrupt() events are deferred until the next interruptible operation. Does not return until at least the specified number of milliseconds has elapsed.

Parameters

ms to sleep before returning, in milliseconds of uptime.

Code for postDelayed from View class:

/**
 * <p>Causes the Runnable to be added to the message queue, to be run
 * after the specified amount of time elapses.
 * The runnable will be run on the user interface thread.</p>
 *
 * @param action The Runnable that will be executed.
 * @param delayMillis The delay (in milliseconds) until the Runnable
 *        will be executed.
 *
 * @return true if the Runnable was successfully placed in to the
 *         message queue.  Returns false on failure, usually because the
 *         looper processing the message queue is exiting.  Note that a

document.getElementById("elementID").scrollIntoView();

Same thing, but wrapping it in a function:

function scrollIntoView(eleID) {
   var e = document.getElementById(eleID);
   if (!!e && e.scrollIntoView) {
       e.scrollIntoView();
   }
}

This even works in an IFrame on an iPhone.

Example of using getElementById: http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_document_getelementbyid

In IE 5.5+, you can use the contentWindow property:

iframe.height = iframe.contentWindow.document.scrollHeight;

In Netscape 6 (assuming firefox as well), contentDocument property:

iframe.height = iframe.contentDocument.scrollHeight

I think list comprehension is one of the cleanest ways that doesn't need any additional imports:

>>> d={"foo": 1, "bar": 2, "baz": 3}
>>> a = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a
[1, 2, 3]

Of if you want the values as individual variables then use multiple-assignment:

>>> a,b,c = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a,b,c
(1, 2, 3)

I have used RxPY which has some nice threading functions to solve this in a fairly clean manner. No queues, and I have provided a function that runs on the main thread after completion of the background thread. Here is a working example:

import rx
from rx.scheduler import ThreadPoolScheduler
import time
import tkinter as tk

class UI:
   def __init__(self):
      self.root = tk.Tk()
      self.pool_scheduler = ThreadPoolScheduler(1) # thread pool with 1 worker thread
      self.button = tk.Button(text="Do Task", command=self.do_task).pack()

   def do_task(self):
      rx.empty().subscribe(
         on_completed=self.long_running_task, 
         scheduler=self.pool_scheduler
      )

   def long_running_task(self):
      # your long running task here... eg:
      time.sleep(3)
      # if you want a callback on the main thread:
      self.root.after(5, self.on_task_complete)

   def on_task_complete(self):
       pass # runs on main thread

if __name__ == "__main__":
    ui = UI()
    ui.root.mainloop()

Another way to use this construct which might be cleaner (depending on preference):

tk.Button(text="Do Task", command=self.button_clicked).pack()

...

def button_clicked(self):

   def do_task(_):
      time.sleep(3) # runs on background thread
             
   def on_task_done():
      pass # runs on main thread

   rx.just(1).subscribe(
      on_next=do_task, 
      on_completed=lambda: self.root.after(5, on_task_done), 
      scheduler=self.pool_scheduler
   )

for the former (3.1) for nn in (00..99) ; do ... works but for nn in (000..999) ; do ... does not work both will work on version 4.1 ; haven't tested printf behaviour (bash --version gave the version info)

This can be done in java 8 using Stream.

import java.util.stream.Stream;

String[] stringList = {"Red", "Orange", "Yellow", "Green", "Blue", "Violet", "Orange", "Blue"};

boolean contains = Stream.of(stringList).anyMatch(x -> x.equals(say.getText());

If what you want is to show with an alert() the content of an array of objects, i recomend you to define in the object the method toString() so with a simple alert(MyArray); the full content of the array will be shown in the alert.

Here is an example:

//-------------------------------------------------------------------
// Defininf the Point object
function Point(CoordenadaX, CoordenadaY) {
    // Sets the point coordinates depending on the parameters defined
    switch (arguments.length) {
        case 0:
            this.x = null;
            this.y = null;
            break;
        case 1:
            this.x = CoordenadaX;
            this.y = null;
            break;
        case 2:
            this.x = CoordenadaX;
            this.y = CoordenadaY;
            break;
    }
    // This adds the toString Method to the point object so the 
    // point can be printed using alert();
    this.toString = function() {
        return " (" + this.x + "," + this.y + ") ";
    };
 }

Then if you have an array of points:

var MyArray = [];
MyArray.push ( new Point(5,6) );
MyArray.push ( new Point(7,9) );

You can print simply calling:

alert(MyArray);

Hope this helps!

It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:

If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.

So I think in your example, the server should return a 416 since it's not a valid byte range for that file.

plt.autoscale() worked for me.

It's not too pretty, but if you have to implement only very few radio buttons for the entire site, something like this might also be an option:

<%=Html.RadioButtonFor(m => m.Gender,"Male",Model.Gender=="Male" ? new { @checked = "checked" } : null)%>

You can do it with a simple jquery code.

$('#Mymodal').modal('hide');

As suggested by A Star, I always use something along the lines of:

DATE(NOW()) - INTERVAL 1 MONTH

Similarly you can do:

NOW() + INTERVAL 5 MINUTE
"2013-01-01 00:00:00" + INTERVAL 10 DAY

and so on. Much easier than typing DATE_ADD or DATE_SUB all the time :)!

You've pretty much nailed it, however Mustache templates can also be compiled.

Mustache is missing helpers and the more advanced blocks because it strives to be logicless. Handlebars' custom helpers can be very useful, but often end up introducing logic into your templates.

Mustache has many different compilers (JavaScript, Ruby, Python, C, etc.). Handlebars began in JavaScript, now there are projects like django-handlebars, handlebars.java, handlebars-ruby, lightncandy (PHP), and handlebars-objc.

iTerm2 - an alternative to Terminal - has an option to use configurable system-wide hotkey to show/hide (initially set to Alt+Space, disabled by default)

Also I had an issue because I was versioning the application in IIS level like below:

If doing this then the configuration at the Configure method should append the version number like below:

app.UseSwaggerUI(options =>
{
    options.SwaggerEndpoint("/1.0/swagger/V1/swagger.json", "Static Data Service");
});

Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.

That's why you can't use something 'not hashable' as a dict key, like a list:

>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable

You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

To pass XML content, you need to wrap the content in a Reader, and unmarshal that instead:

JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

StringReader reader = new StringReader("xml string here");
Person person = (Person) unmarshaller.unmarshal(reader);

In Laravel 8.6, the following works for me in a controller:

$id = auth()->user()->id;

If you are using sass as style preprocessor, you can switch back to native Sass compiler for dev dependency by:

npm install node-sass --save-dev

So that you can keep using /deep/ for development.

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

For example:

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

works, while:

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

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

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

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

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

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

This works for me at runtime too:

UltraPictureBox1.Image = My.Resources.MyPicture

No strings involved and if I change the name it is automatically updated by refactoring.

Although @ruakh gave a good answer, I will add some alternatives for completeness:

You could in fact use even var Omega = 'Ω' in JavaScript, but only if your JavaScript code is:

• inside an event attribute, as in onclick="var Omega = '&#937'; alert(Omega)" or
• in a script element inside an XHTML (or XHTML + XML) document served with an XML content type.

In these cases, the code will be first (before getting passed to the JavaScript interpreter) be parsed by an HTML parser so that character references like Ω are recognized. The restrictions make this an impractical approach in most cases.

You can also enter the O character as such, as in var Omega = 'O', but then the character encoding must allow that, the encoding must be properly declared, and you need software that let you enter such characters. This is a clean solution and quite feasible if you use UTF-8 encoding for everything and are prepared to deal with the issues created by it. Source code will be readable, and reading it, you immediately see the character itself, instead of code notations. On the other hand, it may cause surprises if other people start working with your code.

Using the \u notation, as in var Omega = '\u03A9', works independently of character encoding, and it is in practice almost universal. It can however be as such used only up to U+FFFF, i.e. up to \uffff, but most characters that most people ever heard of fall into that area. (If you need “higher” characters, you need to use either surrogate pairs or one of the two approaches above.)

You can also construct a character using the String.fromCharCode() method, passing as a parameter the Unicode number, in decimal as in var Omega = String.fromCharCode(937) or in hexadecimal as in var Omega = String.fromCharCode(0x3A9). This works up to U+FFFF. This approach can be used even when you have the Unicode number in a variable.

replace('regex', 'replacement');
replaceAll('regex', 'replacement');

In your example,

String hi = "Hello World!"
String no_o = hi.replaceAll("o", "");

Use this to list Grantee too and remove (PG_monitor and Public) for Postgres PaaS Azure.

SELECT grantee,table_catalog, table_schema, table_name, privilege_type
FROM   information_schema.table_privileges 
WHERE  grantee not in ('pg_monitor','PUBLIC');

I'll cover each point separately.

1. Some evil code may steal your lock (very popular this one, also has an "accidentally" variant)

   I'm more worried about accidentally. What it amounts to is that this use of this is part of your class' exposed interface, and should be documented. Sometimes the ability of other code to use your lock is desired. This is true of things like Collections.synchronizedMap (see the javadoc).

2. All synchronized methods within the same class use the exact same lock, which reduces throughput

   This is overly simplistic thinking; just getting rid of synchronized(this) won't solve the problem. Proper synchronization for throughput will take more thought.

3. You are (unnecessarily) exposing too much information

   This is a variant of #1. Use of synchronized(this) is part of your interface. If you don't want/need this exposed, don't do it.

Can't you set the Loglevel in httpd.conf to debug? (I'm using FreeBSD)

ee usr/local/etc/apache22/httpd.conf

change loglevel :

'LogLevel: Control the number of messages logged to the error_log. Possible values include: debug, info, notice, warn, error, crit, alert, emerg.'

Try changing to debug and re-checking the error log after that.

While Tats_innit's answer has a nice touch to it, I had to do it a bit differently since I have more than one progress bar on the page.

here's my solution:

JSfiddle: http://jsfiddle.net/vacNJ/

HTML (example):

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="60"></div>
</div>

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="50"></div>
</div>

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="40"></div>
</div>

?

JavaScript:

setTimeout(function(){

    $('.progress .bar').each(function() {
        var me = $(this);
        var perc = me.attr("data-percentage");

        var current_perc = 0;

        var progress = setInterval(function() {
            if (current_perc>=perc) {
                clearInterval(progress);
            } else {
                current_perc +=1;
                me.css('width', (current_perc)+'%');
            }

            me.text((current_perc)+'%');

        }, 50);

    });

},300);

@Tats_innit: Using setInterval() to dynamically recalc the progress is a nice solution, thx mate! ;)

EDIT:

A friend of mine wrote a nice jquery plugin for custom twitter bootstrap progress bars. Here's a demo: http://minddust.github.com/bootstrap-progressbar/

Here's the Github repo: https://github.com/minddust/bootstrap-progressbar

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

The easiest way to do it is to use the End method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.

Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")

If you can't use End, then you would have to use a loop.

Dim start_cell As Range, end_cell As Range

Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell

Do Until IsEmpty(end_cell.Offset(1, 0))
    Set end_cell = end_cell.Offset(1, 0)
Loop

Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")

Just want to reiterate this will work in pandas >= 0.9.1:

In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]: 
                           ID

I'm creating an issue about detecting integer overflows also.

EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247

Update as it helps others:

To have all columns as str, one can do this (from the comment):

pd.read_csv('sample.csv', dtype = str)

To have most or selective columns as str, one can do this:

# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str'  for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)

If you can not use it directly and if you encounter this error: Blocked a frame with origin "http://www..com" from accessing a cross-origin frame. You can use postMessage() instead of using the function directly.

JPQL mostly is case-insensitive. One of the things that is case-sensitive is Java entity names. Change your query to:

"SELECT r FROM FooBar r"

You could use the following query:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 
            ON table1.id IN (table2.user_one, table2.user_two)
WHERE   table2.user_one IS NULL;

Although, depending on your indexes on table2 you may find that two joins performs better:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 AS t1
            ON table1.id = t1.user_one
        LEFT JOIN table2 AS t2
            ON table1.id = t2.user_two
WHERE   t1.user_one IS NULL
AND     t2.user_two IS NULL;

If you are currently using the MongoDB 3.3 Repository (as officially currently suggested by MongoDB website) you should take in consideration that the package name used for version 3.3 is:

mongodb-org-unstable

Then the proper installation command for this version will be:

sudo apt-get install -y mongodb-org-unstable

Considering this, I will rather suggest to use the current latest stable version (v3.2) until the v3.3 becomes stable, the commands to install it are listed below:

Download the v3.2 Repository key:

wget -qO - https://www.mongodb.org/static/pgp/server-3.2.asc | sudo apt-key add -

If you work with Ubuntu 12.04 or Mint 13 add the following repository:

echo "deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

If you work with Ubuntu 14.04 or Mint 17 add the following repository:

echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

If you work with Ubuntu 16.04 or Mint 18 add the following repository:

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

Update the package list and install mongo:

sudo apt-get update
sudo apt-get install -y mongodb-org

I've had a hard fight with this problem for months, and the only solution that worked for me is this:

var landingUrl = "http://www.ytopic.es"; //URL complete
$window.location.href = landingUrl;

One thing you can do is this:

$(this)[0].value = "Something";

This allows jQuery to return the javascript object for that element, and you can bypass jQuery Functions.

In my case, Git is using Windows to store credentials.

All you have to do is remove the stored credentials stored in your Windows account:

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

The results = 'hide' option doesn't prevent other messages to be printed. To hide them, the following options are useful:

• {r, error=FALSE}
• {r, warning=FALSE}
• {r, message=FALSE}

In every case, the corresponding warning, error or message will be printed to the console instead.

Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.

One use case for optimistic locking is to have your application use the database to allow one of your threads / hosts to 'claim' a task. This is a technique that has come in handy for me on a regular basis.

The best example I can think of is for a task queue implemented using a database, with multiple threads claiming tasks concurrently. If a task has status 'Available', 'Claimed', 'Completed', a db query can say something like "Set status='Claimed' where status='Available'. If multiple threads try to change the status in this way, all but the first thread will fail because of dirty data.

Note that this is a use case involving only optimistic locking. So as an alternative to saying "Optimistic locking is used when you don't expect many collisions", it can also be used where you expect collisions but want exactly one transaction to succeed.

Valgrind one-liner:

valgrind --tool=massif --pages-as-heap=yes --massif-out-file=massif.out ./test.sh; grep mem_heap_B massif.out | sed -e 's/mem_heap_B=\(.*\)/\1/' | sort -g | tail -n 1

Note use of --pages-as-heap to measure all memory in a process. More info here: http://valgrind.org/docs/manual/ms-manual.html

This will slow down your command significantly.

In order to escape single- and double-quotes, you have to double them up:

$value = 'This is a quote, "I said, 'Hi'"';

$value = str_replace( "'", "''", $value ); 

$value = str_replace( '"', '""', $value );

$query = "INSERT INTO TableName ( TextFieldName ) VALUES ( '$value' ) ";

etc...

            children: [
              Text(
                'BoTToM',
                textAlign: TextAlign.center,
                style: TextStyle(fontSize: 33),
              ),
            ],
          ),
        ),
      ],
    );
  }

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

For me, I had to add:

git config --global --unset http.proxy

Basically, you can run:

git config --global -l 

to get the list of all proxy defined, and then use "--unset" to disable them

    String filepath="/tmp/employee.csv";
    FileWriter sw = new FileWriter(new File(filepath));
    CSVWriter writer = new CSVWriter(sw);
    writer.writeAll(allRows);

    String[] header= new String[]{"ErrorMessage"};
    writer.writeNext(header);

    List<String[]> errorData = new ArrayList<String[]>();
    for(int i=0;i<1;i++){
        String[] data = new String[]{"ErrorMessage"+i};
        errorData.add(data);
    }
    writer.writeAll(errorData);

    writer.close();

If you use CocoaPods try to run:

pod deintegrate
pod update

If inserting 'too much data' fails due to the max_allowed_packet setting of the database server, the following warning is raised:

SQLSTATE[08S01]: Communication link failure: 1153 Got a packet bigger than 
'max_allowed_packet' bytes

If this warning is catched as exception (due to the set error handler), the database connection is (probably) lost but the application doesn't know about this (failing inserts can have several causes). The next query in line, which can be as simple as:

SELECT 1 FROM DUAL

Will then fail with the error this SO-question started:

Error while sending QUERY packet. PID=18486

Simple test script to reproduce my explanation, try it with and without the error handler to see the difference in impact:

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
    // error was suppressed with the @-operator
    if (0 === error_reporting()) {
        return false;
    }

    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try
{
    // $oDb is instance of PDO
    var_dump($oDb->query('SELECT 1 FROM DUAL'));

    $oStatement = $oDb->prepare('INSERT INTO `test` (`id`, `message`) VALUES (NULL, :message);');
    $oStatement->bindParam(':message', $largetext, PDO::PARAM_STR);
    var_dump($oStatement->execute());
}
catch(Exception $e)
{
    $e->getMessage();
}
var_dump($oDb->query('SELECT 2 FROM DUAL'));

My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.

It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:

• sudo yum install php php-mysql
• vim /etc/httpd/conf/httpd.conf add something like
• DirectoryIndex index.php index.phtml index.html index.htm to serve php index files also and then restart apache

Don't forget to restart Apache server to take effect - systemctl restart httpd.service

I hope this helps. I first thought my issue was Apache directives, so I post my solution here.

At my last job we ran statistics once a week. If I remember correctly, we scheduled them on a Thursday night, and on Friday the DBAs were very careful to monitor the longest running queries for anything unexpected. (Friday was picked because it was often just after a code release, and tended to be a fairly low traffic day.) When they saw a bad query they would find a better query plan and save that one so it wouldn't change again unexpectedly. (Oracle has tools to do this for you automatically, you tell it the query to optimize and it does.)

Many organizations avoid running statistics out of fear of bad query plans popping up unexpectedly. But this usually means that their query plans get worse and worse over time. And when they do run statistics then they encounter a number of problems. The resulting scramble to fix those issues confirms their fears about the dangers of running statistics. But if they ran statistics regularly, used the monitoring tools as they are supposed to, and fixed issues as they came up then they would have fewer headaches, and they wouldn't encounter them all at once.

If you just want the list, then you should ask here: http://unix.stackexchange.com

The answer is: cd / && find -name *.js

If you want to implement this, you have to specify the language.

For anyone else arriving at this question:

I was performing the most simple jQuery, trying to hide an element:

('#fileselection').hide();

and I was getting the same type of error, "Uncaught TypeError: Object #fileselection has no method 'hide'

Of course, now it is obvious, but I just left off the jQuery indicator '$'. The code should have been:

$('#fileselection').hide();

This fixes the no-brainer problem. I hope this helps someone save a few minutes debugging!

private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivity(intent);
this.finish();

And then you can fetch it like this:

imageUri = Uri.parse(extras.getString("imageUri"));

You can use the familiar Matplotlib style calling a figure and subplot, but you simply need to specify the current axis using plt.gca(). An example:

plt.figure(1)
plt.subplot(2,2,1)
df.A.plot() #no need to specify for first axis
plt.subplot(2,2,2)
df.B.plot(ax=plt.gca())
plt.subplot(2,2,3)
df.C.plot(ax=plt.gca())

etc...

echo '\x12\x02'

will not be interpreted, and will literally write the string \x12\x02 (and append a newline) to the specified serial port. Instead use

echo -n ^R^B

which you can construct on the command line by typing CtrlVCtrlR and CtrlVCtrlB. Or it is easier to use an editor to type into a script file.

The stty command should work, unless another program is interfering. A common culprit is gpsd which looks for GPS devices being plugged in.

WARNING: This answer is useful if you have problems with JAVA_HOME environmental variable and the direction of that. If you do not have this problem, you should not try this solution.

If you have this error and you tried with flutter doctor --android-licenses or sdkmanager --licenses and you got a problem with your JAVA_HOME environmental variable, then you have to read this.

I have a MacOS Catalina ant I could resolve this problem successfully with the next steps:

1. Open your terminal
2. Type: open -e .bash_profile (You should see almost two environmental variables: flutter and JAVA_HOME)
3. Save JAVA_HOME environmental variable written there in a textEdit file if you wish and DELETE the JAVA_HOME environmental variable. Save the bash_profile.
4. Go to terminal again and run source $HOME/.bash_profile
5. Try again flutter doctor and you shouldn't see the same error any more.

Please, let me know if you have doubts.

Trust me, you ain't gonna need it...

It should be this way:

h2.myClass looks for h2 with class myClass. But you actually want to apply style for h2 inside .myClass so you can use descendant selector .myClass h2.

h2 {
    color: red;
}

.myClass {
    color: green;
}

.myClass h2 {
    color: blue;
}

This ref will give you some basic idea about the selectors and have a look at descendant selectors

.NET Core is the current version of .NET that you should be using right now (more features , fixed bugs , etc.)

Xamarin is a platform that provides solutions for cross platform mobile problems coded in C# , so that you don't need to use Swift separately for IOS and the same goes for Android.

Copy from php.net sample for inclusive range:

$begin = new DateTime( '2012-08-01' );
$end = new DateTime( '2012-08-31' );
$end = $end->modify( '+1 day' ); 

$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);

foreach($daterange as $date){
    echo $date->format("Ymd") . "<br>";
}

Yes, you can even change it by triggering an event

<input type='text' name='pass'  onclick="(this.type='password')" />


<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">

Have you tried adding a magic comment in the script where you use non-ASCII chars? It should go on top of the script.

#!/bin/env ruby
# encoding: utf-8

It worked for me like a charm.

Sorry to bump an old question but the answer is to count the character length of the cell and not its value.

CellCount = Cells(Row, 10).Value
If Len(CellCount) <= "13" Then
'do something
End If

hope that helps. Cheers

You can remove a column directly in a rails console by typing:
ActiveRecord::Base.remove_column :table_name, :column_name

success only fires if the AJAX call is successful, i.e. ultimately returns a HTTP 200 status. error fires if it fails and complete when the request finishes, regardless of success.

In jQuery 1.8 on the jqXHR object (returned by $.ajax) success was replaced with done, error with fail and complete with always.

However you should still be able to initialise the AJAX request with the old syntax. So these do similar things:

// set success action before making the request
$.ajax({
  url: '...',
  success: function(){
    alert('AJAX successful');
  }
});

// set success action just after starting the request
var jqxhr = $.ajax( "..." )
  .done(function() { alert("success"); });

This change is for compatibility with jQuery 1.5's deferred object. Deferred (and now Promise, which has full native browser support in Chrome and FX) allow you to chain asynchronous actions:

$.ajax("parent").
    done(function(p) { return $.ajax("child/" + p.id); }).
    done(someOtherDeferredFunction).
    done(function(c) { alert("success: " + c.name); });

This chain of functions is easier to maintain than a nested pyramid of callbacks you get with success.

However, please note that done is now deprecated in favour of the Promise syntax that uses then instead:

$.ajax("parent").
    then(function(p) { return $.ajax("child/" + p.id); }).
    then(someOtherDeferredFunction).
    then(function(c) { alert("success: " + c.name); }).
    catch(function(err) { alert("error: " + err.message); });

This is worth adopting because async and await extend promises improved syntax (and error handling):

try {
    var p = await $.ajax("parent");
    var x = await $.ajax("child/" + p.id);
    var c = await someOtherDeferredFunction(x);
    alert("success: " + c.name);
}
catch(err) { 
    alert("error: " + err.message); 
}

Here is a simple HTML and JavaScript solution I prefer:

//js function to allow only checking of one weekday checkbox at a time:

function checkOnlyOne(b){

var x = document.getElementsByClassName('daychecks');
var i;

for (i = 0; i < x.length; i++) {
  if(x[i].value != b) x[i].checked = false;
}
}


Day of the week:
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Monday" />Mon&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Tuesday" />Tue&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Wednesday" />Wed&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Thursday" />Thu&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Friday" />Fri&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Saturday" />Sat&nbsp;&nbsp;&nbsp;
<input class="daychecks" onclick="checkOnlyOne(this.value);" type="checkbox" name="reoccur_weekday" value="Sunday" />Sun&nbsp;&nbsp;&nbsp;<br /><br />

Interesting info about MSCorlib:

• The .NET 2.0 assembly will reference and use the 2.0 mscorlib.The .NET 1.1 assembly will reference the 1.1 mscorlib but will use the 2.0 mscorlib at runtime (due to hard-coded version redirects in theruntime itself)
• In GAC there is only one version of mscorlib, you dont find 1.1 version on GAC even if you have 1.1 framework installed on your machine. It would be good if somebody can explain why MSCorlib 2.0 alone is in GAC whereas 1.x version live inside framework folder
• Is it possible to force a different runtime to be loaded by the application by making a config setting in your app / web.config? you won’t be able to choose the CLR version by settings in the ConfigurationFile – at that point, a CLR will already be running, and there can only be one per process. Immediately after the CLR is chosen the MSCorlib appropriate for that CLR is loaded.

If you maintain two layouts, all UI thread should be terminated.

If you use AsynTask, then you can easily call .cancel() method inside onDestroy() method of current activity.

@Override
protected void onDestroy (){
    removeDialog(DIALOG_LOGIN_ID); // remove loading dialog
    if (loginTask != null){
        if (loginTask.getStatus() != AsyncTask.Status.FINISHED)
            loginTask.cancel(true); //cancel AsyncTask
    }
    super.onDestroy();
}

For AsyncTask, read more in "Cancelling a task" section at here.

Update: Added condition to check status, as it can be only cancelled if it is in running state. Also note that the AsyncTask can only be executed one time.

Other option is to use ArrayUtils.toArray in org.apache.commons.lang3

ArrayUtils.toArray("elem1","elem2")

In newer versions of typescript you can use:

type Customers = Record<string, Customer>

In older versions you can use:

var map: { [email: string]: Customer; } = { };
map['[email protected]'] = new Customer(); // OK
map[14] = new Customer(); // Not OK, 14 is not a string
map['[email protected]'] = 'x'; // Not OK, 'x' is not a customer

You can also make an interface if you don't want to type that whole type annotation out every time:

interface StringToCustomerMap {
    [email: string]: Customer;
}

var map: StringToCustomerMap = { };
// Equivalent to first line of above

To disable the resize property, use the following CSS property:

resize: none;

• You can either apply this as an inline style property like so:

  <textarea style="resize: none;"></textarea>
  

• or in between <style>...</style> element tags like so:

  textarea {
      resize: none;
  }
