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&gt; obsolete.This method is obsolete,it has been replaced by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

For example:

    BitmapImage bitmap = new BitmapImage();
     
    byte[] buffer = GetHugeByteArray(); // from some external source
    using (MemoryStream stream = new MemoryStream(buffer, false))
    {
        bitmap.BeginInit();
        bitmap.CacheOption = BitmapCacheOption.OnLoad;
        bitmap.StreamSource = stream;
        bitmap.EndInit();
        bitmap.Freeze();
    }

Can you tell me any more about `using`?

**Edit:**

As was discussed in the comments of JaredPar&#39;s post, this question is more concerned with an implementation of `Using` in VS2003.  It was pointed out that `Using` was not introduced until .NET 2.0 (VS2005).  JaredPar posted an equivalent workaround.

I am looking for a way to do daily deployments and keep the database scripts in line with releases. 

Currently, we have a fairly decent way of deploying our source, we have unit code coverage, continuous integration and rollback procedures.  

The problem is keeping the database scripts in line with a release. Everyone seems to try the script out on the test database then run them on live, when the ORM mappings are updated (that is, the changes goes live) then it picks up the new column. 

The first problem is that none of the scripts HAVE to be written anywhere, generally everyone &quot;attempts&quot; to put them into a Subversion folder but some of the lazier people just run the script on live and most of the time no one knows who has done what to the database.

The second issue is that we have 4 test databases and they are ALWAYS out of line and the only way to truly line them back up is to do a restore from the live database. 

I am a big believer that a process like this needs to be simple, straightforward and easy to use in order to help a developer, not hinder them. 

What I am looking for are techniques/ideas that make it EASY for the developer to want to record their database scripts so they can be ran as part of a release procedure. **A process that the developer would want to follow**.

Any stories, use cases or even a link would helpful.

I&#39;ve built the x86 Boost libraries many times, but I can&#39;t seem to build x64 libraries. I start the &quot;Visual Studio 2005 x64 Cross Tools Command Prompt&quot; and run my usual build:

    bjam --toolset=msvc --build-type=complete --build-dir=c:\build install

But it still produces x86 .lib files (I verified this with dumpbin /headers).
What am I doing wrong?

I&#39;ve added a weakly named assembly to my [Visual&amp;nbsp;Studio&amp;nbsp;2005][1] project (which is strongly named). I&#39;m now getting the error:

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:

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 two solutions in my workspace, say A and B.

Solution A is an older project which I finished coding some time ago.
In solution B, I need to use some classes from Solution A. To do so, I add a reference to the dll of one of the projects in solution A.

The problem is when I try to debug. I want to be able to step into A&#39;s code as well. Visual studio is not able to load the code for these classes (&quot;There is no source code available for the current location.&quot;) and I can only view the disassembly, which is not useful.

The only way I know to debug classes from solution A is by running solution B, detach all processes (in the Debug menu item) and attach the process from solution A.

However, this is very inconvenient and I can only debug A OR B at once.

Is there a way to allow stepping into the code of referenced dlls (for which I do have the source code)?


----------
**Solution:** My mistake was that I thought that a project can only be part of a single solution. In fact, a project can be part of any number of solutions.&lt;br/&gt;
When you need to reference the old project, you should simply add the project to the solution. This is done by right clicking the new solution in the Solution Explorer &gt; Add &gt; Existing Project.&lt;br/&gt;
Then, you&#39;ll be able to add the project reference. As others wrote, you should probably completely avoid using dll references to your own code (or other code you might need to change and debug).

A very good reference to how solutions should be designed can be found in [MSDN][1].

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&#39;ve had a *serious* issue with my Visual Studio 2008 setup. I receive the ever-so-useful error &#39;A problem has been encountered while loading the setup components. Canceling setup.&#39; whenever I try to uninstall, reinstall or repair Visual Studio 2008 (team system version). If I can&#39;t resolve this issue I have no choice but to completely wipe my computer and start again which will take all day long! I&#39;ve recently received very strange errors when trying to build projects regarding components running out of memory (despite having ~2gb physical memory free at the time) which has rendered my current VS install useless.

Note I installed VS2005 shell version using the vs_setup.msi file in the SQL Server folder *after* I had installed VS2008, in order to gain access to the SQL Server 2005 Reporting Services designer in Business Intelligence Development Studio (this is inexplicably unavailable in VS2008).

Does anyone have any solutions to this problem?

**P.S.**: I know this isn&#39;t directly related to programming, however I feel this *is* appropriate to SO as it is directly related to my *ability* to program at all!

**Note**: A colleague found a [solution to this problem](#114781), hopefully this should help others with this problem.

What is the difference between Release and Debug modes in Visual Studio?

Using Visual Studio 2005.

Is there anything in the .sln or .vcproj files (or anywhere else) that defines the project type / subtype? 

Edit: What I mean is that when you create a project, you first choose a language (e.g. Visual C#), then a project type (e.g. Windows) and then a subtype (e.g. Console Application).

Where is this information stored within the VS files?






 

How do you tell the Visual Studio project type from an existing Visual Studio project

    	return 0;

I can see the GUID in the &#39;Assembly Information&#39; dialog in under project properties, and at the moment I have just copied it to a const in the code. The GUID will never change, so this is not that bad of a solution, but it would be nice to access it directly. Is there a way to do this?

I do not see dumpbin.exe on my system. I have Visual Studio 2005 on my system. When I type dumpbin on the command line, it says unrecognizable command.

This is driving me crazy. Ever since I installed ReSharper 4, &lt;kbd&gt;F12&lt;/kbd&gt; no longer seems to work. If you look at the all the ReSharper short cuts in the Goto sub menu Declaration doesn&#39;t have any assigned!

The only way I can go to declaration is by using &lt;kbd&gt;Alt&lt;/kbd&gt; and &lt;kbd&gt;`&lt;/kbd&gt; and then selecting Declaration. 

I have tried un-installing and re-installing ReSharper with no luck, I have also, in ReSharper option asked it to use the default Visual Studio Key Bindings but that doesn&#39;t to work either. 

Interestingly, when I do use &lt;kbd&gt;Alt&lt;/kbd&gt; and &lt;kbd&gt;`&lt;/kbd&gt; I actually get two entries for the Declaration option.

Has anyone come across this problem?

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?

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?

Can I exclude a folder or files when I publish a web site in Visual Studio 2005?  I have various resources that I want to keep at hand in the Solution Explorer, such as alternate config files for various environments, but I don&#39;t really want to publish them to the server.  Is there some way to exclude them?  When using other project types, such as a .dll assembly, I can set a file&#39;s Build Action property to &quot;None&quot; and its Copy to Output Directory property to &quot;Do not copy&quot;.  I cannot find any similar settings for files in a web site.

If the IDE does not offer this feature, does anyone have good technique for handling such files?

I have a web application that I&#39;m working on (ASP.NET2.0 with C#, using VS2005). Everything was working fine, and all of a sudden I get the error:

`Error	1	The name &#39;Label1&#39; does not exist in the current context`

and 43 others of the sort for each time that I used a control in my codebehind of the page.

This is only happening for 1 page. And it&#39;s as if the codebehind isn&#39;t recognizing the controls. Another interesting thing is that the intellisense isn&#39;t picking up any of the controls either..

I have tried to  clean the solution file, delete the obj file, exclude the files from the project then re-add them, close VS and restart it, and even restart my computer, but none of these have worked.

I am working on machine with XP Dutch version installed on it. Visual studio 2005 is installed in English. I&#39;m having the annoying problem while debugging that all .NET Framework exception message appear in Dutch, which make them really worthless. I tried to change this to English by setting the regional settings in the control panel to US English and then reinstalling the .NET Framework 2.0 (English version) but apparently this did not solve the problem. Does anyone have an idea?

I think my question was missunderstood, I don&#39;t want to change the current culture of the thread. The problem i&#39;m having is when you are debugging and stepping through the code when suddenly one of those exception windows appears with the exception-message in it.
This exception message appears in Dutch and I would like it to appear English. I hope this clarifies the question.

I coded a Mancala game in Java for a college class this past spring, and I used the [Eclipse][1] IDE to write it.  One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen.  [Notepad++][2], my preferred Notepad replacement, also does this.

Another neat and similar feature in Eclipse was the vertical &quot;error bar&quot; to the right of your code (not sure what to call it).  It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like &quot;variable declared but not used&quot;, and if you select a word, boxes appear in the bar for each occurrence of the word in the document.

A screenshot of these features in action:
 ![screenshot][3]

After a half hour of searching, I&#39;ve determined that Visual Studio cannot do this on its own, so my question is:  does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features?

Being able to highlight the current line your cursor is on would be nice too.  I believe the add-in ReSharper can do this, but I&#39;d prefer to use a free add-in rather than purchase one.
