You can look at the

Process.MainWindowTitle

property of p.

Notepad's title will be Filename.txt - Notepad

If you started the process yourself, you can kill it using the Process.Kill() method.

Note that in many (most?) circumstances, killing all instances of a process isn't really a good user experience since the user may have started instances of that process on their own in addition to the instance your program launched / is attempting to close.

Thanks for your reply and can you provide me a sample code for that. – Jul 15 '11 at 18:18
No actually I am trying to write it to the file and while writing I need to check if the file is opened and then I need to close it and write the text to it. – Jul 15 '11 at 18:25

You could do something as mentioned about using an if statement. Assuming you opened the file called test.

 Dim Process() As Process = System.Diagnostics.Process.GetProcessesByName("notepad")      
    For Each p As Process In Process
        If p.MainWindowTitle.Contains("test") Then
            p.Kill()
        End If
    Next

EDIT:

To check for multiple files

simply add or to the .Contains line

If p.MainWindowTitle.Contains("test") Or ("blahblah") Then
p.kill()

Thanks for your valuable answer and I really thank you for this. — , Jul 15 '11 at 18:28
