I do not want multiple instances of a vb.net program running concurrently...
How may I detect this ?

Thanks

If you are using VS 2005, this is actually a project setting. You just check
of a checkbox, and you are all done.

If
UBound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)) > 0 Then
       '    MsgBox("Application is already running...",
MsgBoxStyle.Information, Application.ProductName)
           ActivatePrevInstance("frmswitchboard")
end if

Check out code and links at

If you just want to make sure you don't start another instance of an app,
you can use the GetProcessesByName. There can be issues with this, particularly
in a Terminal Server environment however. Search on "Single Instance" for
more information. My write up with a VB solution is available at http://devauthority.com/blogs/jwooley/archive/2005/07/28/318.aspx.

Hi Rob ,,,

this was my solution this is Terminal server safe :-)   and you may use this
optional ( for instance from a config file )

cause sometimes you might want to have your proggy started with multiple
instances in some situations
