It seems the project was created by a Professional or Ultimate version of Visual Studio and you're using the Express version?

I'm using the express edition on Visual Studio 2008.
And I'm using windows XP Professional SP2

Yes, I gathered that from your screenshot. Was the project also created in VS2008 Express?

lol, that error happens when I try to create a new project, not to open an existing one. Well it happens also when I try to open an existing one!

Just to confirm, are you running VS2008 Express or VS2008 Express Web Developer Edition? The latter doesn't support creating WPF applications.

lol, I'm using only VS2008 Express Edition, not the other one. And I used to create WPF applications, but I don't know what has happened.

Open visual studio command prompt and type in devenv /resetsettings. This will reset VS to factory settings.
Note however, this will reset all VS settings and you might lose all of them.

It showed me that this command doesn't exist.
Actually, I've searched the C: directory (System directory) for devenv, but found nothing.
Please help me!

It's not included in the path of the normal command prompt, it is included in the "visual studio command prompt", conveniently located in the start-menu.
It's also not a command, but the name of the application that you are using as an IDE to write applications. It's located in the "Program Files" folder, under "Microsoft Visual Studio N/Common7/IDE".

Stop panicking; a quick Google-search would have revealed both the location of the app as well as all possible switches.

Firstly, I'm not that idiot so that I don't know the difference between command prompt and VS command prompt that comes with VC++.
Secondly, can't you read that I've searched the whole C: directory for that file?

I wouldn't have asked that question from the first place if I didn't try to Google for its answer.

Open up your start menu and locate Visual Studio; right click on it and select Properties from the context menu - this opens up a window which contains the full path to devenv.exe.

The directory for Visual C# 2008 was C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE and there's no devenv file in it.
BTW, I didn't download the whole package, but only Visual C# 2008 Express Edition!

Aight, that one should accept "devenv" as a command.

Aw, in that case you'd have to install Visual Studio.

Have you tried creating the application in a location other than the temporary directory?

Can you please explain how to do it? Maybe that's my solution. Damn, I'm so tired of searching for a week!

When you do File New Solution, the dialog that appears has a directory to create it in at the bottom. Set it to a sensible directory; for instance I always use d:\dev.

Thank you all for trying to help, but thank God I've solved the problem by going to this directory with CMD:
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE
and typed this in CMD:
VCSExpress.exe /ResetSkipPkgs
And there was no devenv.exe files but this file
Thank you again!

I am creating a new tab onclick of a menu item at run time.....and in this tab i have to add a datagridview..and there is text box and execute button outside this tab...
when i write any query and press execute then the result should be displayed on dridview..bt the problem is i m creating gridview at run time while user clicks an new query tab on menu...so problem is how to take reference of this gridview when i m doing coding on execute button...Like...Here i Have create that tabpage.

You don't seem to have added the DataGridView to the Controls of the TabPage.
What I have done in the past is derive a custom TabPage that has a DataGridView already on it and which accepts a DataTable in its constructor.
public partial class tpDataTable : System.Windows.Forms.TabPage
{
private System.Windows.Forms.DataGridView dataGridView1;
private System.ComponentModel.IContainer components = null ;
public tpDataTable
(
System.Data.DataTable Table
)
{
InitializeComponent() ;
this.dataGridView1.DataSource = Table ;
...
this.tcResults.TabPages.Add ( new tpDataTable ( dt ) ) ;
