UPDATE

"Run as Aministrator" is just a command, enabling the program to continue some operations that require the Administrator privileges, without displaying the UAC alerts.

Even if your user is a member of administrators group, some applications like yours need the Administrator privileges to continue running, because the application is considered not safe, if it is doing some special operation, like editing a system file or something else. This is the reason why Windows needs the Administrator privilege to execute the application and it notifies you with a UAC alert. Not all applications need an Amnistrator account to run, and some applications, like yours, need the Administrator privileges.

If you execute the application with 'run as administrator' command, you are notifying the system that your application is safe and doing something that requires the administrator privileges, with your confirm.

If you want to avoid this, just disable the UAC on Control Panel.

If you want to go further, read the question Difference between "Run as Administrator" and Windows 7 Administrators Group on Microsoft forum or this SuperUser question.

I've found a way to do this with a single line:

runas /user:DOMAIN\USER2 /savecred "powershell -c start-process -FilePath \"'C:\\PATH\\TO\\YOUR\\EXECUTABLE.EXE'\" -verb runAs"

There are a few tricks going on here.

1: We are telling CMD just to run Powershell as DOMAIN\USER2

2: We are passing the "Start-Process" command to Powershell, using the verb "runAs" to elevate DOMAIN\USER2 to Administrator/Elevated privilege mode.

As a general note, the escape characters in the "FilePath" argument must be present (in other words, the "\ & \\ character combinations), and the single quotation (') must surround the EXE path - this way, CMD interprets the FilePath as a single string, then Powershell uses the single quotation to interpret the FilePath as a single argument.

Using the "RunAs" verb to elevate within Powershell: http://ss64.com/ps/syntax-elevate.html

There is a free GUI Tool ServiceSecurityEditor

Which allows you to edit Windows Service permissions. I have successfully used it to give a non-Administrator user the rights to start and stop a service.

I had used "sc sdset" before I knew about this tool.

ServiceSecurityEditor feels like cheating, it's that easy :)

for me the default search in chrome was locked by smartsputnik.ru. and deleting all the entries in registry and also resetting and reinstalling chrome did not helped . except the below solution.

1. Delete related key from the registry entry- Computer\HKEY_LOCAL_MACCHINE\SOFTWARE\Policies\Google\Chrome
2. Delete file - C:\Windows\System32\GroupPolicy\Machine\registry.pol
3. Restart computer and the problem will be solved

The code posted by Jonathan and Shay Levy did not work for me.

Please find the working code below:

If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{   
#"No Administrative rights, it will display a popup window asking user for Admin rights"

$arguments = "& '" + $myinvocation.mycommand.definition + "'"
Start-Process "$psHome\powershell.exe" -Verb runAs -ArgumentList $arguments

break
}
#"After user clicked Yes on the popup, your file will be reopened with Admin rights"
#"Put your code here"

Assuming the application you are attempting to run in the background is CLI based, you can try calling the scheduled jobs using Hidden Start

Also see: http://www.howtogeek.com/howto/windows/hide-flashing-command-line-and-batch-file-windows-on-startup/

You can embed a manifest file in the EXE file, which will cause Windows (7 or higher) to always run the program as an administrator.

You can find more details in Step 6: Create and Embed an Application Manifest (UAC) (MSDN).

Use psexec -s

The s switch will cause it to run under system account which is the same as running an elevated admin prompt. just used it to enable WinRM remotely.

This is the universal and best solution for this:

If WScript.Arguments.Count <> 1 Then WScript.Quit 1
RunAsAdmin
Main

Sub RunAsAdmin()
    Set Shell = CreateObject("WScript.Shell")
    Set Env = Shell.Environment("VOLATILE")
    If Shell.Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
        Env("CurrentDirectory") = Shell.CurrentDirectory
        ArgsList = ""
        For i = 1 To WScript.Arguments.Count
            ArgsList = ArgsList & """ """ & WScript.Arguments(i - 1)
        Next
        CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & ArgsList & """", , "runas", 5
        WScript.Sleep 100
        Env.Remove("CurrentDirectory")
        WScript.Quit
    End If
    If Env("CurrentDirectory") <> "" Then Shell.CurrentDirectory = Env("CurrentDirectory")
End Sub

Sub Main()
    'Your code here!
End Sub

Advantages:

1) The parameter injection is not possible.
2) The number of arguments does not change after the elevation to administrator and then you can check them before you elevate yourself.
3) You know for real and immediately if the script runs as an administrator. For example, if you call it from a control panel uninstallation entry, the RunAsAdmin function will not run unnecessarily because in that case you are already an administrator. Same thing if you call it from a script already elevated to administrator.
4) The window is kept at its current size and position, as it should be.
5) The current directory doesn't change after obtained administrative privileges.

Disadvantages: Nobody

Solutions that did not work

No: The - create a shortcut [ -> Compatibility -> "run this program as an administrator" ] solution does not work.

This option is greyed out in Windows 7. Even with UAC disabled

No: The runas /env /user:domain\Administrator <program.exe/command you want to execute> is also not sufficient because it will prompt the user for the admin password.

Solution that worked

Yes: Disable UAC -> Create a job using task scheduler, this worked for me.

• Create a job under task scheduler and make it run as a user with administrator permissions.
• Explicitly mark: "Run with highest privileges"
• Disable UAC so there will be no prompt to run this task

You can let the script enable UAC afterwards by editing the registry if you would want. In my case this script is ran only once by creation of a windows virtual machine, where UAC is disabled in the image.

Still looking forward for the best approach for a script run as admin without too much hassle.

For a massive speed increase, use NumPy's where function.

Setup

Create a two-column DataFrame with 100,000 rows with some zeros.

df = pd.DataFrame(np.random.randint(0,3, (100000,2)), columns=list('ab'))

Fast solution with numpy.where

df['b'] = np.where(df.a.values == 0, np.nan, df.b.values)

Timings

%timeit df['b'] = np.where(df.a.values == 0, np.nan, df.b.values)
685 µs ± 6.4 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit df.loc[df['a'] == 0, 'b'] = np.nan
3.11 ms ± 17.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Numpy's where is about 4x faster

Since it's a NodeList, not an Array, you shouldn't really be using brackets or casting to Array. The property way to get the first node is:

document.getElementsByName(id).item(0)

You can just cast that:

var script = <HTMLScriptElement> document.getElementsByName(id).item(0)

Or, extend NodeList:

interface HTMLScriptElementNodeList extends NodeList
{
    item(index: number): HTMLScriptElement;
}
var scripts = <HTMLScriptElementNodeList> document.getElementsByName('script'),
    script = scripts.item(0);

Easiest Way in Passing A Variable-Length 2D Array

Most clean technique for both C & C++ is: pass 2D array like a 1D array, then use as 2D inside the function.

#include <stdio.h>

void func(int row, int col, int* matrix){
    int i, j;
    for(i=0; i<row; i++){
        for(j=0; j<col; j++){
            printf("%d ", *(matrix + i*col + j)); // or better: printf("%d ", *matrix++);
        }
        printf("\n");
    }
}

int main(){
    int matrix[2][3] = { {0, 1, 2}, {3, 4, 5} };
    func(2, 3, matrix[0]);

    return 0;
}

_{Internally, no matter how many dimensions an array has, C/C++ always maintains a 1D array. And so, we can pass any multi-dimensional array like this.}

I looked into this before buying a Mac Mini. The answer is, essentially, no. You pretty much have to buy a Leopard Mac to do iPhone SDK development for apps that run on non-jailbroken iPhones.

Not that it's 100% impossible, but it's 99.99% unreasonable. Like changing light bulbs with your feet.

Not only do you have to be in Xcode, but you have to get certificates into the Keychain manager to be able to have Xcode and the iPhone communicate. And you have to set all kinds of setting in Xcode just right.

        var q = from b in listOfBoxes
                group b by b.Owner into g
                select new
                           {
                               Owner = g.Key,
                               Boxes = g.Count(),
                               TotalWeight = g.Sum(item => item.Weight),
                               TotalVolume = g.Sum(item => item.Volume)
                           };

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

If you're changing the layout of an existing ImageView, you should be able to simply get the current LayoutParams, change the width/height, and set it back:

android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);

I don't know if that's your goal, but if it is, this is probably the easiest solution.

I've changed my code like this and it works:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR UPDATE OR DELETE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

DECLARE
      Operation       NUMBER;
      CustomerCode    CHAR(10 BYTE);
BEGIN

IF DELETING THEN 
  Operation := 3;
  CustomerCode := :old_buffer.field1;
END IF;

IF INSERTING THEN 
  Operation := 1;
  CustomerCode := :new_buffer.field1;
END IF;

IF UPDATING THEN 
  Operation := 2;
  CustomerCode := :new_buffer.field1;
END IF;    

// DO SOMETHING ...

This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine

SELECT author FROM lyrics WHERE author LIKE 'B%';

Make sure you have an index on author, though!

Try this also, that is remove new { } and replace it with string.

<%: Html.TextBoxFor(x => x.Age,"0") %>

Indeed, as has been mentioned above (and elsewhere on SO), in order to convert the string to a date, you need a specific date of the month. From the as.Date() manual page:

If the date string does not specify the date completely, the returned answer may be system-specific. The most common behaviour is to assume that a missing year, month or day is the current one. If it specifies a date incorrectly, reliable implementations will give an error and the date is reported as NA. Unfortunately some common implementations (such as glibc) are unreliable and guess at the intended meaning.

A simple solution would be to paste the date "01" to each date and use strptime() to indicate it as the first day of that month.

For those seeking a little more background on processing dates and times in R:

In R, times use POSIXct and POSIXlt classes and dates use the Date class.

Dates are stored as the number of days since January 1st, 1970 and times are stored as the number of seconds since January 1st, 1970.

So, for example:

d <- as.Date("1971-01-01")
unclass(d)  # one year after 1970-01-01
# [1] 365

pct <- Sys.time()  # in POSIXct
unclass(pct)  # number of seconds since 1970-01-01
# [1] 1450276559
plt <- as.POSIXlt(pct)
up <- unclass(plt)  # up is now a list containing the components of time
names(up)
# [1] "sec"    "min"    "hour"   "mday"   "mon"    "year"   "wday"   "yday"   "isdst"  "zone"  
# [11] "gmtoff"
up$hour
# [1] 9

To perform operations on dates and times:

plt - as.POSIXlt(d)
# Time difference of 16420.61 days

And to process dates, you can use strptime() (borrowing these examples from the manual page):

strptime("20/2/06 11:16:16.683", "%d/%m/%y %H:%M:%OS")
# [1] "2006-02-20 11:16:16 EST"

# And in vectorized form:
dates <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
strptime(dates, "%d%b%Y")
# [1] "1960-01-01 EST" "1960-01-02 EST" "1960-03-31 EST" "1960-07-30 EDT"

You can use code like this

The filter is empty string. The filename is AnyName but not blank

        openFileDialog.FileName = "AnyFile";
        openFileDialog.Filter = string.Empty;
        openFileDialog.CheckFileExists = false;
        openFileDialog.CheckPathExists = false;

Replace

List<String> list=Arrays.asList(split);

to

List<String> list = New ArrayList<>();
list.addAll(Arrays.asList(split));

or

List<String> list = new ArrayList<>(Arrays.asList(split));

or

List<String> list = new ArrayList<String>(Arrays.asList(split));

or (Better for Remove elements)

List<String> list = new LinkedList<>(Arrays.asList(split));

If I get your question correctly, you want to also know the names of the files generated inside the temporary directory? If so, try this:

import os
import tempfile

with tempfile.TemporaryDirectory() as tmp_dir:
    # generate some random files in it
     files_in_dir = os.listdir(tmp_dir)

string = "i'm from New York"
string.split(/\s+/).each{ |word,i| word.capitalize! unless i > 0 }.join(' ')
# => I'm from New York

There is a package called yum-utils that builds on YUM and contains a tool called repoquery that can do this.

$ repoquery --help | grep -E "list\ files" 
  -l, --list            list files in this package/group

Combined into one example:

$ repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

On at least one RH system, with rpm v4.8.0, yum v3.2.29, and repoquery v0.0.11, repoquery -l rpm prints nothing.

If you are having this issue, try adding the --installed flag: repoquery --installed -l rpm.

DNF Update:

To use dnf instead of yum-utils, use the following command:

$ dnf repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

Use this code

Environment.Exit(0);

use 0 as the int if you don't want to return anything.

You can disable constraints in Oracle but not indexes. There's a command to make an index ununsable but you have to rebuild the index anyway, so I'd probably just write a script to drop and rebuild the indexes. You can use the user_indexes and user_ind_columns to get all the indexes for a schema or use dbms_metadata:

select dbms_metadata.get_ddl('INDEX', u.index_name) from user_indexes u;

if it's too long for one page, use the longtable package. and if it's too wide for the page, use p{width} in place of l,r, or c for the column specifier. you can also go smaller than \small, i.e. \footnotesize and \tiny. I would consult the setspace package for options on how to remove the double space, though it's probably \singlespace or something like that.

Based on @MarcGravell's answer, here's a version that works in Unity C#.

ObjectsClass foo = this;
foreach(var prop in foo.GetType().GetProperties()) {
    Debug.Log("{0}={1}, " + prop.Name + ", " + prop.GetValue(foo, null));
}

You need to create an instance of the type that expose the Output method:

static void Main(string[] args)
    {
        var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

        var class1Type = DLL.GetType("DLL.Class1");

        //Now you can use reflection or dynamic to call the method. I will show you the dynamic way

        dynamic c = Activator.CreateInstance(class1Type);
        c.Output(@"Hello");

        Console.ReadLine();
     }

I made following changes in web.config to get the SOAP (Request/Response) Envelope. This will output all of the raw SOAP information to the file trace.log.

You need to put the worksheet identifier in your range statements as shown below ...

 Option Explicit
 Dim ws As Worksheet, a As Range

Sub forEachWs()

For Each ws In ActiveWorkbook.Worksheets
Call resizingColumns
Next

End Sub

Sub resizingColumns()
ws.Range("A:A").ColumnWidth = 20.14
ws.Range("B:B").ColumnWidth = 9.71
ws.Range("C:C").ColumnWidth = 35.86
ws.Range("D:D").ColumnWidth = 30.57
ws.Range("E:E").ColumnWidth = 23.57
ws.Range("F:F").ColumnWidth = 21.43
ws.Range("G:G").ColumnWidth = 18.43
ws.Range("H:H").ColumnWidth = 23.86
ws.Range("i:I").ColumnWidth = 27.43
ws.Range("J:J").ColumnWidth = 36.71
ws.Range("K:K").ColumnWidth = 30.29
ws.Range("L:L").ColumnWidth = 31.14
ws.Range("M:M").ColumnWidth = 31
ws.Range("N:N").ColumnWidth = 41.14
ws.Range("O:O").ColumnWidth = 33.86

path = path.substring(0, path.length() - 5);

In my case, i was not able to see logs because there is some text in Filter field, which caused results of console.log to disappear. Once we clear text in Filter field, it should show.

Both function and perform similarly, but still differ in following ways.

Web application:

1. We can't include C# and VB page in single web application.

2. We can set up dependencies between multiple projects.

3. Can not edit individual files after deployment without recompiling.

4. Right choice for enterprise environments where multiple developers work unitedly for creating,testing and deployment.

Web site:

1. Can mix VB and C# page in single website.
2. Can not establish dependencies.
3. Edit individual files after deployment.
4. Right choice when one developer will responsible for creating and managing entire website.

=VLOOKUP(lookup_value,table_array,col_index_num,range_lookup) will solve this issue.

This will search for a value in the first column to the left and return the value in the same row from a specific column.

Q. List the name of each show, and the number of different times it has been held. List the show which has been held most often first.

event_id show_id event_name judge_id
0101    01  Dressage        01
0102    01  Jumping         02
0103    01  Led in          01
0201    02  Led in          02
0301    03  Led in          01
0401    04  Dressage        04
0501    05  Dressage        01
0502    05  Flag and Pole   02

Ans:

select event_name, count(show_id) as held_times from event 
group by event_name 
order by count(show_id) desc

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

If you do this for testing you could use Quickcheck (this is a Java port I've been working on).

import static net.java.quickcheck.generator.PrimitiveGeneratorSamples.*;

TimeUnit anyEnumValue = anyEnumValue(TimeUnit.class); //one value

It supports all primitive types, type composition, collections, different distribution functions, bounds etc. It has support for runners executing multiple values:

import static net.java.quickcheck.generator.PrimitiveGeneratorsIterables.*;

for(TimeUnit timeUnit : someEnumValues(TimeUnit.class)){
    //..test multiple values
}

The advantage of Quickcheck is that you can define tests based on a specification where plain TDD works with scenarios.

To get the content of a directory you can use

$files = Get-ChildItem "C:\Users\gerhardl\Documents\My Received Files\"

Then you can loop over this variable as well:

for ($i=0; $i -lt $files.Count; $i++) {
    $outfile = $files[$i].FullName + "out" 
    Get-Content $files[$i].FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

An even easier way to put this is the foreach loop (thanks to @Soapy and @MarkSchultheiss):

foreach ($f in $files){
    $outfile = $f.FullName + "out" 
    Get-Content $f.FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

It's been a while, but last time I had something similar:

ROLLBACK TRAN

or trying to

COMMIT

what had allready been done free'd everything up so I was able to clear things out and start again.

The accepted answer works pretty good. I wanted more control so I added a couple of functions more to the script:

function unmuteVideo() {
    player.unMute();
    return false;
  }
  function muteVideo() {
    player.mute();
    return false;
  }
  function setVolumeVideo(volume) {
    player.setVolume(volume);
    return false;
  }

And here is the HTML:

<br>
<button type="button" onclick="unmuteVideo();">Unmute Video</button>
<button type="button" onclick="muteVideo();">Mute Video</button>
<br>
<br>
<button type="button" onclick="setVolumeVideo(100);">Volume 100%</button>
<button type="button" onclick="setVolumeVideo(75);">Volume 75%</button>
<button type="button" onclick="setVolumeVideo(50);">Volume 50%</button>
<button type="button" onclick="setVolumeVideo(25);">Volume 25%</button>

Now you have more control of the sound... Check the reference URL for more:

Building on the previous answers, you can leverage the fact that True is -1 and False is 0 and shorten your code like this:

Sub Button167_Click()
  Range("Y12").Value = _
    Abs(Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value > 0)
End Sub

If the checkbox is checked, .Value = 1.

Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value > 0 returns True.

Applying the Abs function converts True to 1.

If the checkbox is unchecked, .Value = -4146.

Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value > 0 returns False.

Applying the Abs function converts False to 0.

Simply use this:

List<string> list = new List<string>() { "single value" };

You can even omit the () braces:

List<string> list = new List<string> { "single value" };

Update: of course this also works for more than one entry:

List<string> list = new List<string> { "value1", "value2", ... };

For me the issue was that I was converting an existing project to maven, created the folder structures according to the documentation and it was showing the 'main' folder as part of the package. I followed the instructions similar to Jon Skeet / JWoodchuck and went into the Java build path, removed all broken build paths, and then added my build path to be 'src/main/java' and 'src/test/java', as well as the resources folders for each, and it resolved the issue.

Waking up an old thread here I see, but I felt the urge to add the "new" .xlsx format.

According to http://filext.com/file-extension/XLSX the extension for .xlsx is application/vnd.openxmlformats-officedocument.spreadsheetml.sheet. It might be a good idea to include it when checking for mime types!

1. Open Postman.
2. Enter URL in the URL bar http://{server:port}/json/metallica/post.
3. Click Headers button and enter Content-Type as header and application/json in value.
4. Select POST from the dropdown next to the URL text box.
5. Select raw from the buttons available below URL text box.
6. Select JSON from the following dropdown.

7. In the textarea available below, post your request object:

   {
    "title" : "test title",
    "singer" : "some singer"
   }
   

8. Hit Send.

9. Refer to screenshot below:

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

Tutorial is not really required for this. Read up on encapsulation

private String myField; //"private" means access to this is restricted

public String getMyField()
{
     //include validation, logic, logging or whatever you like here
    return this.myField;
}
public void setMyField(String value)
{
     //include more logic
     this.myField = value;
}

Like a lot of other languages, you can initialize variables at the class level, the constructor, or a method. It is up to the developer to decide what is best in their particular case. But below are a list of best practices when it comes to deciding.

Class level variables

Usually, you will declare all your variables here that will be used in the rest of you component. You can initialize them if the value doesn't depend on anything else, or use const keyword to create constants if they will not change.

export class TestClass{
    let varA: string = "hello";
}

Constructor

Normally it's best practice to not do anything in the constructor and just use it for classes that will be injected. Most of the time your constructor should look like this:

   constructor(private http: Http, private customService: CustomService) {}

this will automatically create the class level variables, so you will have access to customService.myMethod() without having to do it manually.

NgOnInit

NgOnit is a lifecycle hook provided by the Angular 2 framework. Your component must implement OnInit in order to use it. This lifecycle hook gets called after the constructor is called and all the variables are initialized. The bulk of your initialization should go here. You will have the certainty that Angular has initialized your component correctly and you can start doing any logic you need in OnInit versus doing things when your component hasn't finished loading properly.

Here is an image detailing the order of what gets called:

https://angular.io/docs/ts/latest/guide/lifecycle-hooks.html

TLDR

If you are using Angular 2 framework and need to interact with certain lifecycle events, use the methods provided by the framework for this to avoid problems.

You are trying to access an XLS file. However, you are using XSSFWorkbook and XSSFSheet class objects. These classes are mainly used for XLSX files.

For XLS file: HSSFWorkbook & HSSFSheet
For XLSX file: XSSFSheet & XSSFSheet

So in place of XSSFWorkbook use HSSFWorkbook and in place of XSSFSheet use HSSFSheet.

So your code should look like this after the changes are made:

HSSFWorkbook workbook = new HSSFWorkbook(file);

HSSFSheet sheet = workbook.getSheetAt(0);

This should accomplish what you want to do. I just tested it on a sheet of mine; let me know if this doesn't work. LTrim is if you only have leading spaces; the Trim function can be used as well as it takes care of leading and trailing spaces. Replace the range of cells in the area I have as "A1:C50" and also make sure to change "Sheet1" to the name of the sheet you're working on.

Dim cell As Range, areaToTrim As Range
Set areaToTrim = Sheet1.Range("A1:C50")
For Each cell In areaToTrim
    cell.Value = LTrim(cell.Value)
Next cell

It's about Shebang

$latlng='{"lat":29.5345741,"lng":75.0342196}';
$latlng=json_decode($latlng,TRUE); // array
echo "Lat=".$latlng['lat'];
echo '<br/>';
echo "Lng=".$latlng['lng'];
echo '<br/>';



$latlng2='{"lat":29.5345741,"lng":75.0342196}';
$latlng2=json_decode($latlng2); // object
echo "Lat=".$latlng2->lat;
echo '<br/>';
echo "Lng=".$latlng2->lng;
echo '<br/>';

The solution is very simple and worked for me.

Try this :

git pull --rebase <url>

then

git push -u origin master

Have a look and see if the the JDK is at:

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

For what it's worth, for Gecko-based browsers you can't condition this thing off of :visited due to the resulting privacy leaks. See http://hacks.mozilla.org/2010/03/privacy-related-changes-coming-to-css-vistited/

I was getting this when the app deployed. In my case, I chose "This is a full trust application" on the project security tab, and that fixed it.

To find all the matching strings, use String's scan method.

str = "A 54mpl3 string w1th 7 numb3rs scatter36 ar0und"
str.scan(/\d+/)
#=> ["54", "3", "1", "7", "3", "36", "0"]

If you want, MatchData, which is the type of the object returned by the Regexp match method, use:

str.to_enum(:scan, /\d+/).map { Regexp.last_match }
#=> [#<MatchData "54">, #<MatchData "3">, #<MatchData "1">, #<MatchData "7">, #<MatchData "3">, #<MatchData "36">, #<MatchData "0">]

The benefit of using MatchData is that you can use methods like offset:

match_datas = str.to_enum(:scan, /\d+/).map { Regexp.last_match }
match_datas[0].offset(0)
#=> [2, 4]
match_datas[1].offset(0)
#=> [7, 8]

See these questions if you'd like to know more:

• "How do I get the match data for all occurrences of a Ruby regular expression in a string?"
• "Ruby regular expression matching enumerator with named capture support"
• "How to find out the starting point for each match in ruby"

Reading about special variables $&, $', $1, $2 in Ruby will be helpful too.

Randomly assigns Alpha, Numeric, Caps and Special per character then validates the password. If it doesn't contain each of the above, randomly assigns a new character from the missing element to a random existing character then recursively validates until a password is formed:

function createPassword(length) {
    var alpha = "abcdefghijklmnopqrstuvwxyz";
    var caps = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    var numeric = "0123456789";
    var special = "!$^&*-=+_?";

    var options = [alpha, caps, numeric, special];

    var password = "";
    var passwordArray = Array(length);

    for (i = 0; i < length; i++) {
        var currentOption = options[Math.floor(Math.random() * options.length)];
        var randomChar = currentOption.charAt(Math.floor(Math.random() * currentOption.length));
        password += randomChar;
        passwordArray.push(randomChar);
    }

    checkPassword();

    function checkPassword() {
        var missingValueArray = [];
        var containsAll = true;

        options.forEach(function (e, i, a) {
            var hasValue = false;
            passwordArray.forEach(function (e1, i1, a1) {
                if (e.indexOf(e1) > -1) {
                    hasValue = true;
                }
            });

            if (!hasValue) {
                missingValueArray = a;
                containsAll = false;
            }
        });

        if (!containsAll) {
            passwordArray[Math.floor(Math.random() * passwordArray.length)] = missingValueArray.charAt(Math.floor(Math.random() * missingValueArray.length));
            password = "";
            passwordArray.forEach(function (e, i, a) {
                password += e;
            });
            checkPassword();
        }
    }

    return password;
}

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

COALESCE is more modern function that is a part of ANSI-92 standard.

NVL is Oracle specific, it was introduced in 80's before there were any standards.

In case of two values, they are synonyms.

However, they are implemented differently.

NVL always evaluates both arguments, while COALESCE usually stops evaluation whenever it finds the first non-NULL (there are some exceptions, such as sequence NEXTVAL):

SELECT  SUM(val)
FROM    (
        SELECT  NVL(1, LENGTH(RAWTOHEX(SYS_GUID()))) AS val
        FROM    dual
        CONNECT BY
                level <= 10000
        )

This runs for almost 0.5 seconds, since it generates SYS_GUID()'s, despite 1 being not a NULL.

SELECT  SUM(val)
FROM    (
        SELECT  COALESCE(1, LENGTH(RAWTOHEX(SYS_GUID()))) AS val
        FROM    dual
        CONNECT BY
                level <= 10000
        )

This understands that 1 is not a NULL and does not evaluate the second argument.

SYS_GUID's are not generated and the query is instant.

select MY_SEQ_NAME.currval from DUAL;

Keep in mind that it only works if you ran select MY_SEQ_NAME.nextval from DUAL; in the current sessions.

you could also use this:

public static class Extensions
 {

        public static string RemovePrefix(this string o, string prefix)
        {
            if (prefix == null) return o;
            return !o.StartsWith(prefix) ? o : o.Remove(0, prefix.Length);
        }

        public static string RemoveSuffix(this string o, string suffix)
        {
            if(suffix == null) return o;
            return !o.EndsWith(suffix) ? o : o.Remove(o.Length - suffix.Length, suffix.Length);
        }

    }

I am adding this A because I got caught with a bizarre version of this which really had me scratching my head for about a hour until I spotted the root cause. My load was failing because of multiple repeats of this format

<path>/linit.o:(.rodata1.libs+0x50): multiple definition of `lua_lib_BASE'
<path>/linit.o:(.rodata1.libs+0x50): first defined here

I turned out to be a bug in my Makefile magic where I had a list of C files and using vpath etc., so the compiles would pick them up from the correct directory in hierarchy. However one C file was repeated in the list, at the end of one line and the start of the next so the gcc load generated by the make had the .o file twice on the command line. Durrrrh. The multiple definitions were from multiple occurances of the same file. The linker ignored duplicates apart from static initialisers!

When you define a variable outside the scope of a function, that variable's value is actually written into your executable file. This means you can only use a constant value. Since you don't know everything about the runtime environment at compile time (which classes are available, what is their structure, etc.), you cannot create objective c objects until runtime, with the exception of constant strings, which are given a specific structure and guaranteed to stay that way. What you should do is initialize the variable to nil and use +initialize to create your image. initialize is a class method which will be called before any other method is called on your class.

Example:

NSImage *imageSegment = nil;
+ (void)initialize {
    if(!imageSegment)
        imageSegment = [[NSImage alloc] initWithContentsOfFile:@"/User/asd.jpg"];
}
- (id)init {
    self = [super init];
    if (self) {
        // Initialization code here.
    }

    return self;
}

In XCode 7.3 I encountered the same question, I 've made the mistake because: Name in (info.plist -->Bundle identifier) is not the same as (target-->build settings -->packaging-->Product bundle identifier). Just make the same, that solved the problem.

C-style variadic functions are supported in C++.

However, most C++ libraries use an alternative idiom e.g. whereas the 'c' printf function takes variable arguments the c++ cout object uses << overloading which addresses type safety and ADTs (perhaps at the cost of implementation simplicity).

I also had a similar requirement where I need to import .png images. I have stored these images in public folder. So the following approach worked for me.

<img src={process.env.PUBLIC_URL + './Images/image1.png'} alt="Image1"></img> 

In addition to the above I have tried using require as well and it also worked for me. I have included the images inside the Images folder in src directory.

<img src={require('./Images/image1.png')}  alt="Image1"/>

As simple as this...

setSize(220, 400);
setLocationRelativeTo(null);  

or if you are using a frame then set the frame to

frame.setSize(220, 400);
frame.setLocationRelativeTo(null);  

For clarification, from the docs:

If the component is null, or the GraphicsConfiguration associated with this component is null, the window is placed in the center of the screen.

Something that really needs to be pointed out is that there are really two aspects to this question - the theoretical aspect and the implementations aspect.

First, let's look at the theoretical aspect. You need to understand what a process is conceptually to understand the difference between a process and a thread and what's shared between them.

We have the following from section 2.2.2 The Classical Thread Model in Modern Operating Systems 3e by Tanenbaum:

The process model is based on two independent concepts: resource grouping and execution. Sometimes it is use­ful to separate them; this is where threads come in....

He continues:

One way of looking at a process is that it is a way to group related resources together. A process has an address space containing program text and data, as well as other resources. These resource may include open files, child processes, pending alarms, signal handlers, accounting information, and more. By putting them together in the form of a process, they can be managed more easily. The other concept a process has is a thread of execution, usually shortened to just thread. The thread has a program counter that keeps track of which instruc­tion to execute next. It has registers, which hold its current working variables. It has a stack, which contains the execution history, with one frame for each proce­dure called but not yet returned from. Although a thread must execute in some process, the thread and its process are different concepts and can be treated sepa­rately. Processes are used to group resources together; threads are the entities scheduled for execution on the CPU.

Further down he provides the following table:

Per process items             | Per thread items
------------------------------|-----------------
Address space                 | Program counter
Global variables              | Registers
Open files                    | Stack
Child processes               | State
Pending alarms                |
Signals and signal handlers   |
Accounting information        |

The above is what you need for threads to work. As others have pointed out, things like segments are OS dependant implementation details.

Note that reversing the whole string (either with the rbegin()/rend() range constructor or with std::reverse) and comparing it with the input would perform unnecessary work.

It's sufficient to compare the first half of the string with the latter half, in reverse:

#include <string>
#include <algorithm>
#include <iostream>
int main()
{
    std::string s;
    std::cin >> s;
    if( equal(s.begin(), s.begin() + s.size()/2, s.rbegin()) )
        std::cout << "is a palindrome.\n";
    else
        std::cout << "is NOT a palindrome.\n";
}

Try using following command. I haven't tried it but I think it should work.

openssl pkcs8 -topk8 -inform PEM -outform DER -in filename -out filename -nocrypt

Wunderbart's post worked for me combined with statler's improvements. Adding a few more comments and syntax cleanup, and also passing back the orientation value and I have the following code feel free to use. Just call readImageFile() function below and you get back the transformed image and the original orientation.

const JpegOrientation = [
    "NOT_JPEG",
    "NORMAL",
    "FLIP-HORIZ",
    "ROT180",
    "FLIP-HORIZ-ROT180",
    "FLIP-HORIZ-ROT270",
    "ROT270",
    "FLIP-HORIZ-ROT90",
    "ROT90"
];


//Provided a image file, determines the orientation of the file based on the EXIF information.
//Calls the "callback" function with an index into the JpegOrientation array. 
//If the image is not a JPEG, returns 0. If  the orientation value cannot be read (corrupted file?) return -1.
function getOrientation(file, callback) {

        }
        
        const length = view.byteLength;
        let offset = 2;
        while (offset < length) {
            
            if (view.getUint16(offset+2, false) <= 8)   //unknown?

Try this: Same as @Nathan-white answer above with minor tweaks.

/* For removing autocomplete highlight color in chrome (note: use this at bottom of your css file). */

Just provide the jQuery val function with an array of values:

var values = "Test,Prof,Off";
$('#strings').val(values.split(','));

And to get the selected values in the same format:

values = $('#strings').val();

From Perl HowTo, the most common ways to execute external commands from Perl are:

• my $files = `ls -la` — captures the output of the command in $files
• system "touch ~/foo" — if you don't want to capture the command's output
• exec "vim ~/foo" — if you don't want to return to the script after executing the command
• open(my $file, '|-', "grep foo"); print $file "foo\nbar" — if you want to pipe input into the command

As other people have commented above, using TRUNC will prevent the use of indexes (if there was an index on TIME_CREATED). To avoid that problem, the query can be structured as

SELECT EMP_NAME, DEPT
FROM EMPLOYEE

gcc -I/path -L/path

• -I /path path to include, gcc will find .h files in this path

• -L /path contains library files, .a, .so

Try this:

NSDictionary *textAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [UIColor whiteColor],NSForegroundColorAttributeName,
                                [UIColor whiteColor],NSBackgroundColorAttributeName,nil];
self.navigationController.navigationBar.titleTextAttributes = textAttributes;

From the terminal (osx) I usually use

cordova plugin -l | xargs cordova plugins rm

Pipe, pipe everything!

To expand a bit: this command will loop through the results of cordova plugin -l and feed it to cordova plugins rm.

xargs is one of those commands that you wonder why you didn't know about before. See this tut.

Assuming the application you are attempting to run in the background is CLI based, you can try calling the scheduled jobs using Hidden Start

Try adding root path.

You can solve this by unchecking contextswitchdeadlock from

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

Its undefined because, console.log(response) runs before doCall(urlToCall); is finished. You have to pass in a callback function aswell, that runs when your request is done.

First, your function. Pass it a callback:

function doCall(urlToCall, callback) {
    urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {                              
        var statusCode = response.statusCode;
        finalData = getResponseJson(statusCode, data.toString());
        return callback(finalData);
    });
}

Now:

var urlToCall = "http://myUrlToCall";
doCall(urlToCall, function(response){
    // Here you have access to your variable
    console.log(response);
})

@Rodrigo, posted a good resource in the comments. Read about callbacks in node and how they work. Remember, it is asynchronous code.

Please verify that the required plug-ins are enabled in Settings | Plugins, most likely you've disabled several of them, that's why you don't see all the facet options.

For the step by step tutorial, see: Creating a simple Web application and deploying it to Tomcat.

You can also set it by code, for example:

process.env.NODE_ENV = 'test';

you should try this:

./ refers to the current working directory, except in the require() function. When using require(), it translates ./ to the directory of the current file called. __dirname is always the directory of the current file.

For example, with the following file structure

/home/user/dir/files/config.json

{
  "hello": "world"
}

/home/user/dir/files/somefile.txt

text file

/home/user/dir/dir.js

var fs = require('fs');

console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));

If I cd into /home/user/dir and run node dir.js I will get

{ hello: 'world' }
text file

But when I run the same script from /home/user/ I get

{ hello: 'world' }

Error: ENOENT, no such file or directory './files/somefile.txt'
    at Object.openSync (fs.js:228:18)
    at Object.readFileSync (fs.js:119:15)
    at Object.<anonymous> (/home/user/dir/dir.js:4:16)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)
    at Array.0 (module.js:470:10)
    at EventEmitter._tickCallback (node.js:192:40)

Using ./ worked with require but not for fs.readFileSync. That's because for fs.readFileSync, ./ translates into the cwd (in this case /home/user/). And /home/user/files/somefile.txt does not exist.

Sometimes it is just easier to start over... I apologize if there is any typo, I haven't had the time to test it thoroughly.

movdir = r"C:\Scans"

        old_name = os.path.join( os.path.abspath(root), filename )

        # Separate base from extension
        base, extension = os.path.splitext(filename)

        # Initial new name
        new_name = os.path.join(basedir, base, filename)

        # If folder basedir/base does not exist... You don't want to create it?
        if not os.path.exists(os.path.join(basedir, base)):
            print os.path.join(basedir,base), "not found" 
            continue    # Next filename
        elif not os.path.exists(new_name):  # folder exists, file does not
            shutil.copy(old_name, new_name)
        else:  # folder exists, file exists as well

                   shutil.copy(old_name, new_name)
                   print "Copied", old_name, "as", new_name

clazz.isAssignableFrom(Foo.class) will be true whenever the class represented by the clazz object is a superclass or superinterface of Foo.

clazz.isInstance(obj) will be true whenever the object obj is an instance of the class clazz.

That is:

clazz.isAssignableFrom(obj.getClass()) == clazz.isInstance(obj)

is always true so long as clazz and obj are nonnull.

Since Java 11 you can do it even simpler:

import java.nio.file.Files;

Files.readString(Path path);
Files.readString?(Path path, Charset cs)

Source: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/Files.html#readString(java.nio.file.Path)

You can put <project> in "Where:" box to search from the current Sublime project from the Find in Files menu.

This is more useful than searching from the root folder for when your project is including or excluding particular folders or file extensions.

• Abstract Class contains only declare the method's signature, they can't define the implementation.
• Abstraction class are defined using the keyword abstract .
• Abstract Class is not possible to implement multiple inheritance.
• Latest version of PHP 5 has introduces abstract classes and methods.
• Classes defined as abstract , we are unable to create the object ( may not instantiated )

Create a scope property called selectedIndex, and an itemClicked function:

function MyController ($scope) {
  $scope.collection = ["Item 1", "Item 2"];

  $scope.selectedIndex = 0; // Whatever the default selected index is, use -1 for no selection

  $scope.itemClicked = function ($index) {
    $scope.selectedIndex = $index;
  };
}

Then my template would look something like this:

<div>
      <span ng-repeat="item in collection"
             ng-class="{ 'selected-class-name': $index == selectedIndex }"
             ng-click="itemClicked($index)"> {{ item }} </span>
</div>

Just for reference $index is a magic variable available within ng-repeat directives.

You can use this same sample within a directive and template as well.

I know this question is quite old, but I was looking for a solution to this problem too. The accepted solution is for WinForms not WPF which I think many who come here are looking for.

For anyone looking for a WPF solution, here is a great approach (via Oskar's answer here):

private void myListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DependencyObject obj = (DependencyObject)e.OriginalSource;

    while (obj != null && obj != myListBox)
    {
        if (obj.GetType() == typeof(ListBoxItem))
        {
             // Do something
             break;
         }
         obj = VisualTreeHelper.GetParent(obj);
    }
}

Basically, you walk up the VisualTree until you've either found a parent item that is a ListBoxItem, or you ascend up to the actual ListBox (and therefore did not click a ListBoxItem).

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

Like this:

void * p = (void *)0x28ff44;

Or if you want it as a char *:

char * p = (char *)0x28ff44;

...etc.

If you're pointing to something you really, really aren't meant to change, add a const:

const void * p = (const void *)0x28ff44;
const char * p = (const char *)0x28ff44;

...since I figure this must be some kind of "well-known address" and those are typically (though by no means always) read-only.

$total = count($_FILES['txt_gallery']['name']);
            $filename_arr = [];
            $filename_arr1 = [];
            for( $i=0 ; $i < $total ; $i++ ) {
              $tmpFilePath = $_FILES['txt_gallery']['tmp_name'][$i];
              if ($tmpFilePath != ""){
                $newFilePath = "../uploaded/" .date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
                $newFilePath1 = date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
                if(move_uploaded_file($tmpFilePath, $newFilePath)) {
                  $filename_arr[] = $newFilePath;
                  $filename_arr1[] = $newFilePath1;

                }
              }
            }
            $file_names = implode(',', $filename_arr1);
            var_dump($file_names); exit;

For those who use Postgre 9.5+(I believe most of you do), there is a quite simple and clean solution

ALTER TABLE if exists <tablename> add if not exists <columnname> <columntype>

Thanks to duncan answer, I end up with this:

marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())

Here are a few alternatives:

In [28]: df.query('Col2 != Col2') # Using the fact that: np.nan != np.nan
Out[28]:
   Col1  Col2  Col3
1     0   NaN   0.0

In [29]: df[np.isnan(df.Col2)]
Out[29]:
   Col1  Col2  Col3
1     0   NaN   0.0

If the contents of the list are primitive data types, you can use a comprehension

new_list = [i for i in old_list]

You can nest it for multidimensional lists like:

new_grid = [[i for i in row] for row in grid]

I use GNU Cash and it uses Open Financial Exchange (ofx) http://www.ofx.net/ to download complete transactions and balances from each account of each bank.

Let me emphasize that again, you get a huge list of transactions with OFX into the GNU Cash. Depending on the account type these transactions can be very detailed description of your transactions (purchases+paycheques), investments, interests, etc.

In my case, even though I have Chase debit card I had to choose Chase Credit to make it work. But Chase wants you to enable this OFX feature by logging into your online banking and enable Quicken/MS Money/etc. somewhere in your profile or preferences. Don't call Chase customer support because they know nothing about it.

This service for OFX and GNU Cash is free. I have heard that they charge $10 a month for other platforms.

OFX can download transactions from 348 banks so far. http://www.ofxhome.com/index.php/home/directory

Actualy, OFX also supports making bill payments, stop a check, intrabank and interbank transfers etc. It is quite extensive. See it here: http://ofx.net/AboutOFX/ServicesSupported.aspx

Check out all their awesome documentation!

Here is where they discuss the Warning Message.

String + Format

Warning: Browser support for parsing strings is inconsistent. Because there is no specification on which formats should be supported, what works in some browsers will not work in other browsers.

For consistent results parsing anything other than ISO 8601 strings, you should use String + Format.

moment("12-25-1995", "MM-DD-YYYY");

String + Formats (multiple formats)

If you have more than one format, check out their String + Formats (with an 's').

If you don't know the exact format of an input string, but know it could be one of many, you can use an array of formats.

moment("12-25-1995", ["MM-DD-YYYY", "YYYY-MM-DD"]);

Please checkout the documentation for anything more specific.

Timezone

Checkout Parsing in Zone, the equivalent documentation for timezones.

The moment.tz constructor takes all the same arguments as the moment constructor, but uses the last argument as a time zone identifier.

var b = moment.tz("May 12th 2014 8PM", "MMM Do YYYY hA", "America/Toronto");

EDIT

//...
var dateFormat = "YYYY-M-D H:m"; //<-------- This part will get rid of the warning.

You need add parameter errors='coerce' to function to_numeric:

ID = pd.to_numeric(ID, errors='coerce')

If ID is column:

df.ID = pd.to_numeric(df.ID, errors='coerce')

but non numeric are converted to NaN, so all values are float.

For int need convert NaN to some value e.g. 0 and then cast to int:

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)

Sample:

df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
              ID
0  4806105017087
1  4806105017087
2       CN414149

print (pd.to_numeric(df.ID, errors='coerce'))
0    4.806105e+12
1    4.806105e+12
2             NaN
Name: ID, dtype: float64

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
              ID
0  4806105017087
1  4806105017087
2              0

EDIT: If use pandas 0.25+ then is possible use integer_na:

df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
              ID
0  4806105017087
1  4806105017087
2            NaN

With current HTML5 it should be possible to calculate the md5 hash of a binary file, But I think the step before that would be to convert the banary data BlobBuilder to a String, I am trying to do this step: but have not been successful.

Here is the code I tried: Converting a BlobBuilder to string, in HTML5 Javascript

PostgreSQL does not support IF NOT EXISTS for CREATE DATABASE statement. It is supported only in CREATE SCHEMA. Moreover CREATE DATABASE cannot be issued in transaction therefore it cannot be in DO block with exception catching.

When CREATE SCHEMA IF NOT EXISTS is issued and schema already exists then notice (not error) with duplicate object information is raised.

To solve these problems you need to use dblink extension which opens a new connection to database server and execute query without entering into transaction. You can reuse connection parameters with supplying empty string.

Below is PL/pgSQL code which fully simulates CREATE DATABASE IF NOT EXISTS with same behavior like in CREATE SCHEMA IF NOT EXISTS. It calls CREATE DATABASE via dblink, catch duplicate_database exception (which is issued when database already exists) and converts it into notice with propagating errcode. String message has appended , skipping in the same way how it does CREATE SCHEMA IF NOT EXISTS.

CREATE EXTENSION IF NOT EXISTS dblink;

DO $$
BEGIN
PERFORM dblink_exec('', 'CREATE DATABASE testdb');
EXCEPTION WHEN duplicate_database THEN RAISE NOTICE '%, skipping', SQLERRM USING ERRCODE = SQLSTATE;
END
$$;

This solution is without any race condition like in other answers, where database can be created by external process (or other instance of same script) between checking if database exists and its own creation.

Moreover when CREATE DATABASE fails with other error than database already exists then this error is propagated as error and not silently discarded. There is only catch for duplicate_database error. So it really behaves as IF NOT EXISTS should.

You can put this code into own function, call it directly or from transaction. Just rollback (restore dropped database) would not work.

I had (have) a similar problem in a Java application. I wrote a JDBC driver wrapper around the Oracle driver so all output is sent to a log file.

phpinfo(32) contains everything PHP able to know about particular client, and there is no [windows] computer name

You could also try to include md5-hash-sums or similar do determine whether there are any differences at all. Then, only compare files which have different hashes...

• Make sure the file exists: use os.listdir() to see the list of files in the current working directory
• Make sure you're in the directory you think you're in with os.getcwd() (if you launch your code from an IDE, you may well be in a different directory)
• You can then either:
  • Call os.chdir(dir), dir being the folder where the file is located, then open the file with just its name like you were doing.
  • Specify an absolute path to the file in your open call.
• Remember to use a raw string if your path uses backslashes, like so: dir = r'C:\Python32'
  • If you don't use raw-string, you have to escape every backslash: 'C:\\User\\Bob\\...'
  • Forward-slashes also work on Windows 'C:/Python32' and do not need to be escaped.

Let me clarify how Python finds files:

• An absolute path is a path that starts with your computer's root directory, for example 'C:\Python\scripts..' if you're on Windows.
• A relative path is a path that does not start with your computer's root directory, and is instead relative to something called the working directory. You can view Python's current working directory by calling os.getcwd().

If you try to do open('sortedLists.yaml'), Python will see that you are passing it a relative path, so it will search for the file inside the current working directory. Calling os.chdir will change the current working directory.

Example: Let's say file.txt is found in C:\Folder.

To open it, you can do:

os.chdir(r'C:\Folder')
open('file.txt') #relative path, looks inside the current working directory

or

open(r'C:\Folder\file.txt') #full path

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

To create a component as part of a module you should

1. ng g module newModule to generate a module,
2. cd newModule to change directory into the newModule folder
3. ng g component newComponent to create a component as a child of the module.

UPDATE: Angular 9

Now it doesn't matter what folder you are in when generating the component.

1. ng g module NewMoudle to generate a module.
2. ng g component new-module/new-component to create NewComponent.

Note: When the Angular CLI sees new-module/new-component, it understands and translates the case to match new-module -> NewModule and new-component -> NewComponent. It can get confusing in the beginning, so easy way is to match the names in #2 with the folder names for the module and component.

I faced same issue & it resolved by

ENTRYPOINT ["sh", "/docker-entrypoint.sh"]

For the Dockerfile in the original question it should be like:

ENTRYPOINT ["sh", "/usr/src/app/docker-entrypoint.sh"]

Try this:

SELECT CONVERT(DATE, STUFF(STUFF('01012020', 5, 0, '-'), 3, 0, '-'), 103);

It works with SQL Server 2016.

Also works in ubuntu with Ctrl+E

Well you just remove the desired item from the list using the remove() method of your ArrayAdapter.

A possible way to do that would be:

Object toRemove = arrayAdapter.getItem([POSITION]);
arrayAdapter.remove(toRemove);

Another way would be to modify the ArrayList and call notifyDataSetChanged() on the ArrayAdapter.

arrayList.remove([INDEX]);
arrayAdapter.notifyDataSetChanged();

If you're hosting the page and the iframe on the same domain you can listen for the iframe's Window.DOMContentLoaded event. You have to wait for the original page to fire DOMContentLoaded first, then attach a DOMContentLoaded event listener on the iframe's Window.

Given you have an iframe as follows,

<iframe id="iframe-id" name="iframe-name" src="..."></iframe>

the next snippet will allow you to hook into the iframe's DOMContentLoaded event:

document.addEventListener('DOMContentLoaded', function () {
    var iframeWindow = frames['iframe-name'];
    // var iframeWindow = document.querySelector('#iframe-id').contentWindow
    // var iframeWindow = document.getElementById('iframe-id').contentWindow

    iframeWindow.addEventListener('DOMContentLoaded', function () {
        console.log('iframe DOM is loaded!');
    });
});

Built-in base64, zlib, and rot13 codecs

Strings have encode and decode methods. Usually this is used for converting str to unicode and vice versa, e.g. with u = s.encode('utf8'). But there are some other handy builtin codecs. Compression and decompression with zlib (and bz2) is available without an explicit import:

>>> s = 'a' * 100
>>> s.encode('zlib')
'x\x9cKL\xa4=\x00\x00zG%\xe5'

Similarly you can encode and decode base64:

>>> 'Hello world'.encode('base64')
'SGVsbG8gd29ybGQ=\n'
>>> 'SGVsbG8gd29ybGQ=\n'.decode('base64')
'Hello world'

And, of course, you can rot13:

>>> 'Secret message'.encode('rot13')
'Frperg zrffntr'

Both T1 and T2 can refer to a class containing this variable.
You can then make this variable volatile, and this means that
Changes to that variable are immediately visible in both threads.

See this article for more info.

Volatile variables share the visibility features of synchronized but none of the atomicity features. This means that threads will automatically see the most up-to-date value for volatile variables. They can be used to provide thread safety, but only in a very restricted set of cases: those that do not impose constraints between multiple variables or between a variable's current value and its future values.

And note the pros/cons of using volatile vs more complex means of sharing state.

Why should you need manipulations with packages.config or .csproj files?
The error explicitly says: Use NuGet Package Restore to download them.
Use it accordingly this instruction: https://docs.microsoft.com/en-us/nuget/consume-packages/package-restore-troubleshooting:

Quick solution for Visual Studio users
1.Select the Tools > NuGet Package Manager > Package Manager Settings menu command.
2.Set both options under Package Restore.
3.Select OK.
4.Build your project again.

This is the best code example:

<a_x000D_
 style="color:blue;text-decoration: underline;background: white;"_x000D_
 href="http://aashwin.com/index.php/education/library/"_x000D_
 onmouseover="this.style.color='#0F0'"_x000D_
 onmouseout="this.style.color='#00F'">_x000D_
   Library_x000D_
</a>

Moderator Suggestion: Keep your separation of concerns.

HTML

<a_x000D_
 style="color:blue;text-decoration: underline;background: white;"_x000D_
 href="http://aashwin.com/index.php/education/library/"_x000D_
 class="lib-link">_x000D_
   Library_x000D_
</a>

JS

const libLink = document.getElementsByClassName("lib-link")[0];_x000D_
// The array 0 assumes there is only one of these links,_x000D_
// you would have to loop or use event delegation for multiples_x000D_
// but we won't go into that here_x000D_
libLink.onmouseover = function () {_x000D_
  this.style.color='#0F0'_x000D_
}_x000D_
libLink.onmouseout = function () {_x000D_
  this.style.color='#00F'_x000D_
}

In the Documentation it says there are no import statements in Swift.

Simply use:

let primNumber = PrimeNumberModel()

Thank you for your answer Shereef.

I solved it a little bit differently.

I changed the code of the ViewPager class of the android support library. The method setCurrentItem(int)

changes the page with animation. This method calls an internal method that requires the index and a flag enabling smooth scrolling. This flag is boolean smoothScroll. Extending this method with a second parameter boolean smoothScroll solved it for me. Calling this method setCurrentItem(int index, boolean smoothScroll) allowed me to make it scroll indefinitely.

Here is a full example:

Please consider that only the center page is shown. Moreover did I store the pages seperately, allowing me to handle them with more ease.

private class Page {
  View page;
  List<..> data;
}
// page for predecessor, current, and successor
Page[] pages = new Page[3];




mDayPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
        }

        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

        @Override
        public void onPageScrollStateChanged(int state) {

            if (state == ViewPager.SCROLL_STATE_IDLE) {

                if (mFocusedPage == 0) {
                    // move some stuff from the 
                                            // center to the right here
                    moveStuff(pages[1], pages[2]);

                    // move stuff from the left to the center 
                    moveStuff(pages[0], pages[1]);
                    // retrieve new stuff and insert it to the left page
                    insertStuff(pages[0]);
                }
                else if (mFocusedPage == 2) {


                    // move stuff from the center to the left page
                    moveStuff(pages[1], pages[0]); 
                    // move stuff from the right to the center page
                    moveStuff(pages[2], pages[1]); 
                    // retrieve stuff and insert it to the right page
                                            insertStuff(pages[2]);
                }

                // go back to the center allowing to scroll indefinitely
                mDayPager.setCurrentItem(1, false);
            }
        }
    });

However, without Jon Willis Code I wouldn't have solved it myself.

EDIT: here is a blogpost about this:

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

If You need sth different than AUTO_INCREMENT you can still use triggers.

Since you can never depend on exact comparisons when dealing with floating point computations (such as these ways of calculating the square root), a less error-prone implementation would be

import math

def is_square(integer):
    root = math.sqrt(integer)
    return integer == int(root + 0.5) ** 2

Imagine integer is 9. math.sqrt(9) could be 3.0, but it could also be something like 2.99999 or 3.00001, so squaring the result right off isn't reliable. Knowing that int takes the floor value, increasing the float value by 0.5 first means we'll get the value we're looking for if we're in a range where float still has a fine enough resolution to represent numbers near the one for which we are looking.

This should work <input type="text" id="datepicker">

var dateToday = new Date();
$("#datepicker").datepicker({
    minDate: dateToday,
    onSelect: function(selectedDate) {
    var option = this.id == "datepicker" ? "minDate" : "maxDate",
    instance = $(this).data("datepicker"),
    date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
    dates.not(this).datepicker("option", option, date);
    }
});

Usually you can double click the .py file in Windows explorer to run it. If this doesn't work, you can create a batch file in the same directory with the following contents:

C:\python23\python YOURSCRIPTNAME.py

Then double click that batch file. Or, you can simply run that line in the command prompt while your working directory is the location of your script.

SELECT ... HAVING ... is a good start. Not many developers seem to understand how to use it.

In Python 3.x the process might hang because the output is a byte array instead of a string. Make sure you decode it into a string.

Starting from Python 3.6 you can do it using the parameter encoding in Popen Constructor. The complete example:

process = subprocess.Popen(
    'my_command',
    stdout=subprocess.PIPE,
    stderr=subprocess.STDOUT,
    shell=True,
    encoding='utf-8',
    errors='replace'
)

while True:
    realtime_output = process.stdout.readline()

    if realtime_output == '' and process.poll() is not None:
        break

    if realtime_output:
        print(realtime_output.strip(), flush=True)

Note that this code redirects stderr to stdout and handles output errors.

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

from HERE

int a[20];
int length;
length = sizeof(a) / sizeof(int);

and you can use another way to make your code not be hard-coded to int

Say if you have an array array

you just need to:

int len = sizeof(array) / sizeof(array[0]);

The standard Web Storage, does not say anything about the restoring any of these. So there won't be any standard way to do it. You have to go through the way the browsers implement these, or find a way to backup these before you delete them.

An sql sum of column_name's unique values and sorted by the frequency:

SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name ORDER BY 2 DESC;

My minimalistic solution should work for random numbers in range [min, max). Use srand(time(NULL)) before invoking the function.

int range_rand(int min_num, int max_num) {
    if (min_num >= max_num) {
        fprintf(stderr, "min_num is greater or equal than max_num!\n"); 
    }
    return min_num + (rand() % (max_num - min_num));
} 

I'm very late to answer it. But, I would like to share one example, which I only thought of today. If I told you to cut a piece of paper with dimensions 5m by 5m, then surely you would do that. But suppose I ask you to cut 1000 pieces of paper of the same dimensions. In this case, you won't do the measuring 1000 times; obviously, you would make a frame of 5m by 5m, and then with the help of it you would be able to cut 1000 pieces of paper in less time. So, what you did was make a framework which would do a specific type of task. Instead of performing the same type of task again and again for the same type of applications, you create a framework having all those facilities together in one nice packet, hence providing the abstraction for your application and more importantly many applications.

You want to put the ISNULL inside of the COUNT function, not outside:

Not GOOD: ISNULL(COUNT(field), 0)

GOOD: COUNT(ISNULL(field, 0))

For example :

In MainActivity :

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra(OtherActivity.KEY_EXTRA, yourDataObject);
startActivity(intent);

In OtherActivity :

public static final String KEY_EXTRA = "com.example.yourapp.KEY_BOOK";

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  String yourDataObject = null;

  if (getIntent().hasExtra(KEY_EXTRA)) {
      yourDataObject = getIntent().getStringExtra(KEY_EXTRA);
  } else {
      throw new IllegalArgumentException("Activity cannot find  extras " + KEY_EXTRA);
  }
  // do stuff
}

only css, quite simple I find it:

.checkmark {_x000D_
      display: inline-block;_x000D_
      transform: rotate(45deg);_x000D_
      height: 25px;_x000D_
      width: 12px;_x000D_
      margin-left: 60%; _x000D_
      border-bottom: 7px solid #78b13f;_x000D_
      border-right: 7px solid #78b13f;_x000D_
    }

<div class="checkmark"></div>

While this isn't possible with the video itself, you could use a canvas to draw the frames of the video except for pixels in a color range or whatever. It would take some javascript and such of course. See Video Puzzle (apparently broken at the moment), Exploding Video, and Realtime Video -> ASCII

How about this,

$("body").bind("ajaxSend", function(elm, xhr, s){
   if (s.type == "POST") {
      xhr.setRequestHeader('X-CSRF-Token', getCSRFTokenValue());
   }

To pass CSRF as parameter,

        $.ajax({
            type: "POST",
            url: "file",
            data: { CSRF: getCSRFTokenValue()}
        })
        .done(function( msg ) {
            alert( "Data: " + msg );
        });

Here how I solved it using Cookies:

First of all, inside the website main script:

var browserWindowSize = getCookie("_browserWindowSize");
var newSize = $(window).width() + "," + $(window).height();
var reloadForCookieRefresh = false;

if (browserWindowSize == undefined || browserWindowSize == null || newSize != browserWindowSize) {
    setCookie("_browserWindowSize", newSize, 30);
    reloadForCookieRefresh = true;
}

if (reloadForCookieRefresh)
    window.location.reload();

function setCookie(name, value, days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "") + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

And inside MVC action filter:

public class SetCurrentRequestDataFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // currentRequestService is registered per web request using IoC
        var currentRequestService = iocResolver.Resolve<ICurrentRequestService>();

        if (filterContext.HttpContext.Request.Cookies.AllKeys.Contains("_browserWindowSize"))
        {
            var browserWindowSize = filterContext.HttpContext.Request.Cookies.Get("_browserWindowSize").Value.Split(',');
            currentRequestService.browserWindowWidth = int.Parse(browserWindowSize[0]);
            currentRequestService.browserWindowHeight = int.Parse(browserWindowSize[1]);
        }

    }
}

An eclipse specific alternative limited to the java.library.path JVM parameter allows to set it for a specific source folder rather than for the whole jdk as proposed in another response:

1. select the source folder in which the program to start resides (usually source/test/java)
2. type alt enter to open Properties page for that folder
3. select native in the left panel
4. Edit the native path. The path can be absolute or relative to the workspace, the second being more change resilient.

For those interested on detail on why maven argline tag should be preferred to the systemProperties one, look, for example:

Pick up native JNI files in Maven test (lwjgl)

Ok, I THINK I understand what you want now, and let me clarify to confirm before the query. You want 1 record for each user. For each user, you want their BEST POINTS score record. Of the best points per user, you want the one with the best average time. Once you have all users "best" values, you want the final results sorted with best points first... Almost like ranking of a competition.

So now the query. If the above statement is accurate, you need to start with getting the best point/average time per person and assigning a "Rank" to that entry. This is easily done using MySQL @ variables. Then, just include a HAVING clause to only keep those records ranked 1 for each person. Finally apply the order by of best points and shortest average time.

select
      U.UserName,
      PreSortedPerUser.Point,
      PreSortedPerUser.Avg_Time,
      @UserRank := if( @lastUserID = PreSortedPerUser.User_ID, @UserRank +1, 1 ) FinalRank,
      @lastUserID := PreSortedPerUser.User_ID
   from
      ( select
              S.user_id,
              S.point,
              S.avg_time
           from
              Scores S
           order by
              S.user_id,
              S.point DESC,
              S.Avg_Time ) PreSortedPerUser
         JOIN Users U
            on PreSortedPerUser.user_ID = U.ID,
      ( select @lastUserID := 0,
               @UserRank := 0 ) sqlvars 
   having
      FinalRank = 1
   order by
      Point Desc,
      Avg_Time

Results as handled by SQLFiddle

Note, due to the inline @variables needed to get the answer, there are the two extra columns at the end of each row. These are just "left-over" and can be ignored in any actual output presentation you are trying to do... OR, you can wrap the entire thing above one more level to just get the few columns you want like

select 
      PQ.UserName,
      PQ.Point,
      PQ.Avg_Time
   from
      ( entire query above pasted here ) as PQ

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

SELECT TO_CHAR(created_at, 'YYYY-MM-DD') FROM table; //converts any date format to YYYY-MM-DD

(?<=\[).+?(?=\])

Will capture content without brackets

• (?<=\[) - positive lookbehind for [

• .*? - non greedy match for the content

• (?=\]) - positive lookahead for ]

EDIT: for nested brackets the below regex should work:

(\[(?:\[??[^\[]*?\]))

Use an abstract class instead. So, you would have something like:

public bool Foo<T>() where T : CBase;

//Parent/Children[@  Attribute='value']/@Attribute

This is the case which can be used where element is having 2 attribute and we can get the one attribute with the help of another one.

If you are using SPs and if the sps have multiple Select statements (within if conditions) all those selects needs to be handled with unique field names.

You could pass the messages as explicit URL parameter (appropriately encoded), or store the messages into session (cookie) variable before redirecting and then get the variable before rendering the template. For example:

from flask import session, url_for

def do_baz():
    messages = json.dumps({"main":"Condition failed on page baz"})
    session['messages'] = messages
    return redirect(url_for('.do_foo', messages=messages))

@app.route('/foo')
def do_foo():
    messages = request.args['messages']  # counterpart for url_for()
    messages = session['messages']       # counterpart for session
    return render_template("foo.html", messages=json.loads(messages))

(encoding the session variable might not be necessary, flask may be handling it for you, but can't recall the details)

Or you could probably just use Flask Message Flashing if you just need to show simple messages.

performSelector:withObject:withObject:

You might also want to mention that this method is only for passing maximum 2 arguments, and it cannot be delayed. (such as performSelector:withObject:afterDelay:).

kinda weird that apple only supports 2 objects to be send and didnt make it more generic.

Was facing a similar issue yesterday with our CI server. The app extension could not be signed with the error

Code Sign error: No matching provisioning profiles found: No provisioning profiles with a valid signing identity (i.e. certificate and private key pair) matching the bundle identifier XXX were found.

Note: I had created my provisioning profiles myself from Developer portal (not managed by Xcode).

The error was that I had created the provisioning profiles using the Distribution certificate, but the build settings were set to use the developer certificate. Changing it to use Distribution certificate solved the issue.

Summary: Match the certificate used for creating the provisioning profile in build settings too.

Setting remote repository URL worked for me:

git remote set-url origin https://github.com/path-to-repo/MyRepo.git

Depending on what you want to achieve with the removed scroll you could just fix the element that you want to remove scroll from (on click, or whatever other trigger you'd like to temporarily deactivate scroll)

I was searching around for a "temp no scroll" solution and for my needs, this solved it

make a class

.fixed{
    position: fixed;
}

then with Jquery

var someTrigger = $('#trigger'); //a trigger button
var contentContainer = $('#content'); //element I want to temporarily remove scroll from

contentContainer.addClass('notfixed'); //make sure that the element has the "notfixed" class

//Something to trigger the fixed positioning. In this case we chose a button.
someTrigger.on('click', function(){

    if(contentContainer.hasClass('notfixed')){
        contentContainer.removeClass('notfixed').addClass('fixed');

    }else if(contentContainer.hasClass('fixed')){
        contentContainer.removeClass('fixed').addClass('notfixed');
    };
});

I found that this was a simple enough solution that works well on all browsers, and also makes for simple use on portable devices (i.e. iPhones, tablets etc). Since the element is temporarily fixed, there is no scroll :)

NOTE! Depending on the placement of your "contentContainer" element you might need to adjust it from the left. Which can easily be done by adding a css left value to that element when the fixed class is active

contentContainer.css({
    'left': $(window).width() - contentContainer.width()/2 //This would result in a value that is the windows entire width minus the element we want to "center" divided by two (since it's only pushed from one side)
});

if you want to know the install version of Xcode as well as Swift language current version:

Use below simple command by using Terminal:

1. To get install Xcode Version

 xcodebuild -version

2. To get install Swift language Version

swift --version

Sometimes, you only need this code.

 httpClient.DefaultRequestHeaders.Add("token", token);

Every method (other than a constructor) must have a return type.

public double diameter(){...

-u: disabled by default. When activated, an error message is displayed when using an unconfigured variable.

-v: inactive by default. After activation, the original content of the information will be displayed (without variable resolution) before the information is output.

-x: inactive by default. If activated, the command content will be displayed before the command is run (after variable resolution, there is a ++ symbol).

Compare the following differences:

/ # set -v && echo $HOME
/root
/ # set +v && echo $HOME
set +v && echo $HOME
/root

/ # set -x && echo $HOME
+ echo /root
/root
/ # set +x && echo $HOME
+ set +x
/root

/ # set -u && echo $NOSET
/bin/sh: NOSET: parameter not set
/ # set +u && echo $NOSET

An elegant way to implement this would be to make an extension method, like this:

public static class Extensions
{
    public static List<string> GetSelectedItems(this CheckBoxList cbl)
    {
        var result = new List<string>();

        foreach (ListItem item in cbl.Items)
            if (item.Selected)
                result.Add(item.Value);

        return result;
    }
}

I can then use something like this to compose a string will all values separated by ';':

string.Join(";", cbl.GetSelectedItems());

print(os.path.join(os.path.dirname(__file__))) 

You can also use this way

You can safeguard yourself either of these two ways:

function myFunc(thing) {
    if (thing && thing.foo && thing.foo.bar) {
        // safe to use thing.foo.bar here
    }
}

function myFunc(thing) {
    try {
        var x = thing.foo.bar;
        // do something with x
    } catch(e) {
        // do whatever you want when thing.foo.bar didn't work
    }
}

In the first example, you explicitly check all the possible elements of the variable you're referencing to make sure it's safe before using it so you don't get any unplanned reference exceptions.

In the second example, you just put an exception handler around it. You just access thing.foo.bar assuming it exists. If it does exist, then the code runs normally. If it doesn't exist, then it will throw an exception which you will catch and ignore. The end result is the same. If thing.foo.bar exists, your code using it executes. If it doesn't exist that code does not execute. In all cases, the function runs normally.

The if statement is faster to execute. The exception can be simpler to code and use in complex cases where there may be many possible things to protect against and your code is structured so that throwing an exception and handling it is a clean way to skip execution when some piece of data does not exist. Exceptions are a bit slower when the exception is thrown.

Typically for dynamic lists of items, you use a std::vector.

Generally I use memset or a loop for raw memory dynamic allocation, depending on how variable I anticipate that area of code to be in the future.

You can use standard "ant notation" to exclude directories relative.
This works for me and excludes any .git or node_module directories:

tar -cvf myFile.tar --exclude=**/.git/* --exclude=**/node_modules/*  -T /data/txt/myInputFile.txt 2> /data/txt/myTarLogFile.txt

myInputFile.txt contains:

/dev2/java
/dev2/javascript

Additionally, for our Android friends (API Level 8):

import android.util.Base64

...

Base64.encodeToString(bytes, Base64.DEFAULT);

I think the fastest way is to use grid system with fractions. So your container have 100vw, which is 100% of the window width and 100vh which is 100% of the window height.

Using fractions or 'fr' you can choose the width you like. the sum of the fractions equals to 100%, in this example 4fr. So the first part will be 1fr (25%) and the seconf is 3fr (75%)

More about fr units here.

.container{
  width: 100vw;
  height:100vh; 
  display: grid;
  grid-template-columns: 1fr 3fr;
}

/*You don't need this*/
.div1{
  background-color: yellow;
}

.div2{
  background-color: red;
}

<div class='container'>
  <div class='div1'>This is div 1</div>
  <div class='div2'>This is div 2</div>
</div>

For Unity3D users ...

• VSCode is incredibly faster than VS. Files open instantly from Unity. VS is very slow. VSCode launches instantly. VS takes forever to launch.

• VS can literally compile code, build apps and so on, it's a huge IDE like Unity itself or XCode. VSCode is indeed "just" a full-featured text editor. VSCode is NOT a compiler (far less a huge, build-everything system that can literally create apps and software of all types): VSCode is literally "just a text editor".

• With VSCode, you DO need to install the "Visual Studio Code" package. (Not to be confused with the "Visual Studio" package.) (It seems to me that VS works fine without the VS package, but, with VS Code, you must install Unity's VSCode package.)

• When you first download and install VSCode, simply open any C# file on your machine. It will instantly prompt you to install the needed C# package. This is harmless and easy.

• Unfortunately VSCode generally has only one window! You cannot, really, easily drag files to separate windows. If this is important to you, you may need to go with VS.

• The biggest problem with VS is that the overall concept of settings and preferences are absolutely horrible. In VS, it is all-but impossible to change the font, etc. In contrast, VSCode has FANTASTIC preferences - dead simple, never a problem.

• As far as I can see, every single feature in VS which you use in Unity is present in VSCode. (So, code coloring, jump to definitions, it understands/autocompletes every single thing in Unity, it opens from Unity, double clicking something in the Unity console opens the file to that line, etc etc)

• If you are used to VS. And you want to change to VSCode. It's always hard changing editors, they are so intimate, but it's pretty similar; you won't have a big heartache.

In short if you're a VS for Unity3D user,

and you're going to try VSCode...

1. VSCode is on the order of 19 trillion times faster in every way. It will blow your mind.

2. It does seem to have every feature.

3. Basically VS is the world's biggest IDE and application building system: VSCode is just an editor. (Indeed, that's exactly what you want with Unity, since Unity itself is the IDE.)

4. Don't forget to just click to install the relevant Unity package.

If I'm not mistaken, there is no reason whatsoever to use VS with Unity.

Unity is an IDE so you just need a text editor, and that is what VSCode is. VSCode is hugely better in both speed and preferences. The only possible problem - multiple-windows are a bit clunky in VSCode!

That horrible "double copy" problem in VS ... solved!

If you are using VS with Unity. There is an infuriating problem where often VS will try to open twice, that is you will end up with two or more copies of VS running. Nobody has ever been able to fix this or figure out what the hell causes it. Fortunately, this problem never happens with VSCode.

Installing VSCode on a Mac - unbelievably easy.

There are no installers, etc etc etc. On the download page, you download a zipped Mac app. Put it in the Applications folder and you're done.

Meta files ...

To keep the "Explorer" list of files on the left tidy, in the Unity case:

Hi - I want to write a test to establish that an Exception is not raised in a given circumstance.

That's the default assumption -- exceptions are not raised.

If you say nothing else, that's assumed in every single test.

You don't have to actually write an any assertion for that.

A pool of threads means that all your threads are running, all the time – in other words, the thread function never returns. To give the threads something meaningful to do, you have to design a system of inter-thread communication, both for the purpose of telling the thread that there's something to do, as well as for communicating the actual work data.

Typically this will involve some kind of concurrent data structure, and each thread would presumably sleep on some kind of condition variable, which would be notified when there's work to do. Upon receiving the notification, one or several of the threads wake up, recover a task from the concurrent data structure, process it, and store the result in an analogous fashion.

The thread would then go on to check whether there's even more work to do, and if not go back to sleep.

The upshot is that you have to design all this yourself, since there isn't a natural notion of "work" that's universally applicable. It's quite a bit of work, and there are some subtle issues you have to get right. (You can program in Go if you like a system which takes care of thread management for you behind the scenes.)

As Faizan describes in their answer here:

First of all read the Json File from your assests file using below code.

and then you can simply read this string return by this function as

public String loadJSONFromAsset() {
    String json = null;
    try {
        InputStream is = getActivity().getAssets().open("yourfilename.json");
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();
        json = new String(buffer, "UTF-8");
    } catch (IOException ex) {
        ex.printStackTrace();
        return null;
    }
    return json;
}

and use this method like that

    try {
        JSONObject obj = new JSONObject(loadJSONFromAsset());
        JSONArray m_jArry = obj.getJSONArray("formules");
        ArrayList<HashMap<String, String>> formList = new ArrayList<HashMap<String, String>>();
        HashMap<String, String> m_li;

        for (int i = 0; i < m_jArry.length(); i++) {
            JSONObject jo_inside = m_jArry.getJSONObject(i);
            Log.d("Details-->", jo_inside.getString("formule"));
            String formula_value = jo_inside.getString("formule");
            String url_value = jo_inside.getString("url");

            //Add your values in your `ArrayList` as below:
            m_li = new HashMap<String, String>();
            m_li.put("formule", formula_value);
            m_li.put("url", url_value);

            formList.add(m_li);
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

Undefined offset means there's an empty array key for example:

$a = array('Felix','Jon','Java');

// This will result in an "Undefined offset" because the size of the array
// is three (3), thus, 0,1,2 without 3
echo $a[3];

You can solve the problem using a loop (while):

$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
    // Increase count by 1, thus, $i=1
    $i++;

    $groupname[$i] = base64_decode(base64_decode($row['groupname']));

    // Set the first position of the array to null or empty
    $groupname[0] = "";
}

var filtered = projects;
foreach (var tag in filteredTags) {
  filtered = filtered.Where(p => p.Tags.Contains(tag))
}

The nice thing with this approach is that you can refine search results incrementally.

With your example:

<input type="checkbox" id="c2" name="c2" value="DE039230952"/>

Replace $$ with document.querySelectorAll in the examples:

$$('input') //Every input
$$('[id]') //Every element with id
$$('[id="c2"]') //Every element with id="c2"
$$('input,[id]') //Every input + every element with id
$$('input[id]') //Every input including id
$$('input[id="c2"]') //Every input including id="c2"
$$('input#c2') //Every input including id="c2" (same as above)
$$('input#c2[value="DE039230952"]') //Every input including id="c2" and value="DE039230952"
$$('input#c2[value^="DE039"]') //Every input including id="c2" and value has content starting with DE039
$$('input#c2[value$="0952"]') //Every input including id="c2" and value has content ending with 0952
$$('input#c2[value*="39230"]') //Every input including id="c2" and value has content including 39230

Use the examples directly with:

const $$ = document.querySelectorAll.bind(document);

Some additions:

$$(.) //The same as $([class])
$$(div > input) //div is parent tag to input
document.querySelector() //equals to $$()[0] or $()

set objExcel = CreateObject("Excel.Application")
objExcel.Application.DisplayAlerts = False
set objWorkbook=objExcel.workbooks.add()
objExcel.cells(1,1).value = "Test value"
objExcel.cells(1,2).value = "Test data"
objWorkbook.Saveas "c:\testXLS.xls"
objWorkbook.Close
objExcel.workbooks.close
objExcel.quit
set objExcel = nothing `

To show:

50x50 pixels

<img src="//graph.facebook.com/{{fid}}/picture">

200 pixels width

<img src="//graph.facebook.com/{{fid}}/picture?type=large">

To save (using PHP)

NOTE: Don't use this. See @Foreever's comment below.

$img = file_get_contents('https://graph.facebook.com/'.$fid.'/picture?type=large');
$file = dirname(__file__).'/avatar/'.$fid.'.jpg';
file_put_contents($file, $img);

Where $fid is your user id on Facebook.

NOTE: In case of images marked as "18+" you will need a valid access_token from a 18+ user:

<img src="//graph.facebook.com/{{fid}}/picture?access_token={{access_token}}">

UPDATE 2015:

Graph API v2.0 can't be queried using usernames, you should use userId always.

The children property returns an array of elements, like so:

parent = document.querySelector('.parent');
children = parent.children; // [<div class="child1">]

There are alternatives to querySelector, like document.getElementsByClassName('parent')[0] if you so desire.

Edit: Now that I think about it, you could just use querySelectorAll to get decendents of parent having a class name of child1:

children = document.querySelectorAll('.parent .child1');

The difference between qS and qSA is that the latter returns all elements matching the selector, while the former only returns the first such element.

Also the Pear packages:

http://pear.php.net/package/Mail_Mime http://pear.php.net/package/Mail http://pear.php.net/package/Mail_Queue

sob.

PS: DO NOT use mail() to send those 5000 emails. In addition to what everyone else said, it is extremely inefficient since mail() creates a separate socket per email set, even to the same MTA.

treeset is an ordered set, but you can't access via an items index, just iterate through or go to beginning/end.

export class ClassName extends Component{
      constructor(props){
        super(props);
        this.state = {
          id:parseInt(props.match.params.id,10)
        }
    }
     render(){
        return(
          //Code
          {this.state.id}
        );
}

Perhaps $('#fruit').val(); is not returning an array and you need something like:

$("#fruit").val() || []

http://docs.jquery.com/Attributes/val

You can also check if any process is using this file and show a list of programs you must close to continue like an installer does.

public static string GetFileProcessName(string filePath)
{
    Process[] procs = Process.GetProcesses();
    string fileName = Path.GetFileName(filePath);

    foreach (Process proc in procs)
    {
        if (proc.MainWindowHandle != new IntPtr(0) && !proc.HasExited)
        {
            ProcessModule[] arr = new ProcessModule[proc.Modules.Count];

            foreach (ProcessModule pm in proc.Modules)
            {
                if (pm.ModuleName == fileName)
                    return proc.ProcessName;
            }
        }
    }

    return null;
}

I came up with the following which takes account of rubbish passed in and file_get_contents failing....

function get_lonlat(  $addr  ) {
    try {
            $coordinates = @file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($addr) . '&sensor=true');
            $e=json_decode($coordinates);
            // call to google api failed so has ZERO_RESULTS -- i.e. rubbish address...
            if ( isset($e->status)) { if ( $e->status == 'ZERO_RESULTS' ) {echo '1:'; $err_res=true; } else {echo '2:'; $err_res=false; } } else { echo '3:'; $err_res=false; }
            // $coordinates is false if file_get_contents has failed so create a blank array with Longitude/Latitude.
            if ( $coordinates == false   ||  $err_res ==  true  ) {
                $a = array( 'lat'=>0,'lng'=>0);
                $coordinates  = new stdClass();
                foreach (  $a  as $key => $value)
                {
                    $coordinates->$key = $value;
                }
            } else {
                // call to google ok so just return longitude/latitude.
                $coordinates = $e;

                $coordinates  =  $coordinates->results[0]->geometry->location;
            }

            return $coordinates;
    }
    catch (Exception $e) {
    }

then to get the cords: where $pc is the postcode or address.... $address = get_lonlat( $pc ); $l1 = $address->lat; $l2 = $address->lng;

I'm just learning docker and this got me as well. I stopped the container with that name already and therefore I thought I could run a new container with that name.

Not the case. Just because the container is stopped, doesn't mean it can't be started again, and it keeps all the same parameters that it was created with (including the name).

when I ran docker ps -a that's when I saw all the dummy test containers I created while I was playing around.

No problem, since I don't want those any more I just did docker rm containername at which point my new container was allowed to run with the old name.

Ah, and now that I finish writing this answer, I see Slawosz's comment on Walt Howard's answer above suggesting the use of docker ps -a

This is not memory address This is classname@hashcode
Which is the default implementation of Object.toString()

public String toString() {
    return getClass().getName() + "@" + Integer.toHexString(hashCode());
}

where

Class name = full qualified name or absolute name (ie package name followed by class name) hashcode = hexadecimal format (System.identityHashCode(obj) or obj.hashCode() will give you hashcode in decimal format).

Hint:
The confusion root cause is that the default implementation of Object.hashCode() use the internal address of the object into an integer

This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.

And of course, some classes can override both default implementations either for toString() or hashCode()

If you need the default implementation value of hashcode() for a object which overriding it,
You can use the following method System.identityHashCode(Object x)

You can override ggplots default scales by modifying scale_x_continuous and/or scale_y_continuous. For example:

library(ggplot2)
dat <- data.frame(x = rnorm(100), y = rnorm(100))

ggplot(dat, aes(x,y)) +
  geom_point()

Gives you this:

And overriding the scales can give you something like this:

ggplot(dat, aes(x,y)) +
  geom_point() +
  scale_x_continuous(breaks = round(seq(min(dat$x), max(dat$x), by = 0.5),1)) +
  scale_y_continuous(breaks = round(seq(min(dat$y), max(dat$y), by = 0.5),1))

If you want to simply "zoom" in on a specific part of a plot, look at xlim() and ylim() respectively. Good insight can also be found here to understand the other arguments as well.

There is a computer vision package called HALCON from MVTec whose demos could give you good algorithm ideas. There is plenty of examples similar to your problem that you could run in demo mode and then look at the operators in the code and see how to implement them from existing OpenCV operators.

I have used this package to quickly prototype complex algorithms for problems like this and then find how to implement them using existing OpenCV features. In particular for your case you could try to implement in OpenCV the functionality embedded in the operator find_scaled_shape_model. Some operators point to the scientific paper regarding algorithm implementation which can help to find out how to do something similar in OpenCV. Hope this helps...

I had the same problem and I ended up finding out that this seems to be a known bug in DALI (Eclipse Java Persistence Tools) since at least eclipse 3.8 which could cause the save action in the java editor to be extremly slow.

Since this hasn't been fully resolved in Kepler (20130614-0229) yet and because I don't need JPT/DALI in my eclipse I ended up manually removing the org.eclipse.jpt features and plugins.

What I did was:

1.) exit eclipse

2.) go to my eclipse install directory

cd eclipse

and execute these steps:

*nix:

mkdir disabled
mkdir disabled/features disabled/plugins

mv plugins/org.eclipse.jpt.* disabled/plugins
mv features/org.eclipse.jpt.* disabled/features

windows:

mkdir disabled
mkdir disabled\features 
mkdir disabled\plugins

move plugins\org.eclipse.jpt.* disabled\plugins
for /D /R %D in (features\org.eclipse.jpt.*) do move %D disabled\features

3.) Restart eclipse.

After startup and on first use eclipse may warn you that you need to reconfigure your content-assist. Do this in your preferences dialog.

Done.

After uninstalling DALI/JPT my eclipse feels good again. No more blocked UI and waiting for seconds when saving a file.

Dictionaries are for look ups. It makes sense to ask if an entry exists or not. Lists are usually iterated. It isn't common to ask if L[10] exists but rather if the length of L is 11.

Angular JS does this way.

msie = parseInt((/msie (\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
if (isNaN(msie)) {
  msie = parseInt((/trident\/.*; rv:(\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
}

msie will be positive number if its IE and NaN for other browser like chrome,firefox.

why ?

As of Internet Explorer 11, the user-agent string has changed significantly.

for guys still looking into this issue one thing u need to know is there are different GACutils out there , so u need to make sure that ur using correct GACUTIL to deploy the DLL to correct GAC

for eg: if my dll was complied in 3.5 .net framework and my OS version was 64 bit windows it would be in below location

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\x64

Struggled for 4 stupid days to figure this out
