**For versions *before* Visual studio 2012:**  
It works when I do this:  
find `include &quot;{[a-zA-Z]+\.h}&quot;`,  
replace with `include &lt;\1&gt;`.  
The most relevant parts for your question are the curly braces `{}` and the back reference `\1`: `\n` references to the n&#39;th group indicated by curly braces in the search expression.

**For versions Visual studio 2012 &amp; up:**  
Starting with VS2012 .NET Framework regular expressions are used. So there it should be:  
find `include &quot;([a-zA-Z]+\.h)&quot;`,  
replace with `include &lt;$1&gt;`.

You need to select both Match Case and Regular Expressions for regex expressions with case.
Else [a-z] won&#39;t work.![enter image description here](https://i.stack.imgur.com/GzQPV.jpg)


It&#39;s also possible with the short version:

Is it possible to `break` from a Groovy `.each{Closure}`, or should I be using a classic loop instead?

I am trying to replace all the `#include &quot;whatever.h&quot;` with `#include &lt;whatever.h&gt;` using find and replace functionality in Visual Studio 2005. I used the regex `\#include \&quot;[a-z\.h]+\&quot;` to find the include statement. But I am wondering how frame the replace regex.

`\#include \&lt;[a-z\.h]+\&gt;` did not work and won&#39;t; it replaces the statement `#include &quot;whatever.h&quot;` with `#include &lt;[a-z.h]+&gt;`. How shall I frame the replace regex to retain `whatever.h` as it is?

I got quite a lot of strings (segments of SQL code, actually) with the following format:

    (&#39;ABCDEFG&#39;, 123542, &#39;XYZ 99,9&#39;)

and i need to split this string, using C#, in order to get:

 - &#39;ABCDEFG&#39;
 - 123542
 - &#39;XYZ 99,9&#39;

I was originally using a simple `Split(&#39;,&#39;)`, but since that comma inside the last parameter is causing havoc in the output i need to use Regex to get it. The problem is that i&#39;m still quite noobish in regular expressions and i can&#39;t seem to crack the pattern mainly because inside that string both numerical and alpha-numerical parameters may exist at any time...

What could i use to split that string according to every comma outside the quotes?
Cheers

I&#39;m trying to use the range pattern `[01-12]` in regex to match two digit mm, but this doesn&#39;t work as expected.

Why doesn&#39;t [01-12] range work as expected?

I m looking for regex which checks for at least 6 characters, regardless of which type of character.

Minimum 6 characters regex expression

I have got a text string like this: 

    test1test

I want to check if it contains at least one digit using a regex.

What would this regex look like?

Regex: Check if string contains at least one digit

Why can&#39;t I match the string

    &quot;1234567-1234567890&quot;

with the given regular expression

    \d{7}-\d{10}

with `egrep` from the shell like this:

    egrep \d{7}-\d{10} file

?

Pattern matching digits does not work in egrep?

We would like to use Visual Studio 2005 to work on a local copy of an SVN repository. This local copy has been checked out by Mac OS X (and updates and commits will only be made under Mac OS X, so no problem there), and as a consequence the line endings are UNIX-style.

We fear that Visual Studio will introduce Windows-style line endings. Is it possible to force Visual Studio to use UNIX line endings?

Configure Visual Studio to use UNIX line endings

    #include &lt;algorithm&gt;
    #include &lt;Windows.h&gt;

    int main()
    {
    	int k = std::min(3, 4);
    	return 0;
    }

What is windows doing if I include Windows.h? I can&#39;t use `std::min` in visual studio 2005. The error message is:

    error C2589: &#39;(&#39; : illegal token on right side of &#39;::&#39;
    error C2059: syntax error : &#39;::&#39;

Why is std::min failing when windows.h is included?

I&#39;m trying to understand why the following code doesn&#39;t issue a warning at the indicated place.

    //from limits.h
    #define UINT_MAX 0xffffffff /* maximum unsigned int value */
    #define INT_MAX  2147483647 /* maximum (signed) int value */
                /* = 0x7fffffff */
    
    int a = INT_MAX;
    //_int64 a = INT_MAX; // makes all warnings go away
    unsigned int b = UINT_MAX;
    bool c = false;
    
    if(a &lt; b) // warning C4018: &#39;&lt;&#39; : signed/unsigned mismatch
        c = true;
    if(a &gt; b) // warning C4018: &#39;&lt;&#39; : signed/unsigned mismatch
        c = true;
    if(a &lt;= b) // warning C4018: &#39;&lt;&#39; : signed/unsigned mismatch
        c = true;
    if(a &gt;= b) // warning C4018: &#39;&lt;&#39; : signed/unsigned mismatch
        c = true;
    if(a == b) // no warning &lt;--- warning expected here
        c = true;
    if(((unsigned int)a) == b) // no warning (as expected)
        c = true;
    if(a == ((int)b)) // no warning (as expected)
        c = true;

I thought it was to do with background promotion, but the last two seem to say otherwise.

To my mind, the first `==` comparison is just as much a signed/unsigned mismatch as the others?

I am using Visual Studio 2005. After taking code from version control first, 
 the c#.net application runs correctly. But, after doing some modifications, when I build I am getting the following error:

&gt;Error	383	Unable to copy file &quot;..\root\leaf\Bin\Debug\test.Resources.xml&quot; to
    &quot;Bin\Debug\test.Resources.xml&quot;. Access to the path &#39;Bin\Debug\test.Resources.xml&#39; is
    denied.	li.rollmodel

Does anybody know why this issue is occurring?

**Edit** I can see that my entire project source code folder is Read-only, and I am not able to remove the read-only property.

First, can anybody tell me how to remove the Read-only property for this folder? I have tried removing it but the read-only property persists. I tried from the version-control side also and that did not work, either.

I have used the following namespace to connect my project to the sql server:

    using System.Configuration;

and also used 

    string str=System.Configuration.ConfigurationSettings.AppSettings[&quot;myconnection&quot;];
    SqlConnection oconnection = new SqlConnection(str);
    oconnection.Open();

when I run the program ,an error has been occurred and show the message 

&gt; &#39;System.Configuration.ConfigurationSettings.AppSettings&#39; is
&gt; obsolete.This method is obsolete,it has been replaced by
&gt; &#39;System.Configuration!
&gt; System.Configuration.ConfigurationManager.AppSettings &#39;

 but I have no found ConfigurationManager in that namespace and for `oconnection.Open();` the message is 

&gt; InvalidOperationException

was unhandled.

What can I do?

configurationManager does not exist in the namespace System.Configuration

I would like to search multiple files via eclipse for the following 2 lines:

    private String description;
    
and replace them with these two:

    private String description;

Any ideas on where Im going wrong im sure its a simple fix.

How can I automatically replace all instances of multiple spaces, with a single space, in Javascript?

I&#39;ve tried chaining some `s.replace` but this doesn&#39;t seem optimal.

I&#39;m using jQuery as well, in case it&#39;s a builtin functionality.

I am writing a script for customising a configuration file. I want to replace multiple instances of strings within this file, and I tried using PowerShell to do the job.

It works fine for a single replace, but doing multiple replaces is very slow because each time it has to parse the whole file again, and this file is very large. The script looks like this:

    $original_file = &#39;path\filename.abc&#39;
    $destination_file =  &#39;path\filename.abc.new&#39;
    (Get-Content $original_file) | Foreach-Object {
        $_ -replace &#39;something1&#39;, &#39;something1new&#39;
        } | Set-Content $destination_file

I want something like this, but I don&#39;t know how to write it:

    $original_file = &#39;path\filename.abc&#39;
    $destination_file =  &#39;path\filename.abc.new&#39;
    (Get-Content $original_file) | Foreach-Object {
        $_ -replace &#39;something1&#39;, &#39;something1aa&#39;
        $_ -replace &#39;something2&#39;, &#39;something2bb&#39;
        $_ -replace &#39;something3&#39;, &#39;something3cc&#39;
        $_ -replace &#39;something4&#39;, &#39;something4dd&#39;
        $_ -replace &#39;something5&#39;, &#39;something5dsf&#39;
        $_ -replace &#39;something6&#39;, &#39;something6dfsfds&#39;
        } | Set-Content $destination_file


How to replace multiple strings in a file using PowerShell

I have a very large numpy array (containing up to a million elements) like the one below:

    [0,1,6,5,1,2,7,6,2,3,8,7,3,4,9,8,5,6,11,10,6,7,12,11,7,
    8,13,12,8,9,14,13,10,11,16,15,11,12,17,16,12,13,18,17,13,
    14,19,18,15,16,21,20,16,17,22,21,17,18,23,22,18,19,24,23]

and a small dictionary map for replacing some of the elements in the above array

    {4: 0, 9: 5, 14: 10, 19: 15, 20: 0, 21: 1, 22: 2, 23: 3, 24: 0}

I would like to replace some of the elements according to the map above. The numpy array is really large, and only a small subset of the elements (occurring as keys in the dictionary) will be replaced with the corresponding values. What is the fastest way to do this?
