detect 2nd instance

[Doug Bell]

Hi
can anyone point me in the right direction of detecting if an application is
running so that if a 2nd instance is started it can check and self
terminate?

Thanks

Hi Doug,

If Process.GetProcessesByName
(Process.GetCurrentProcess.ProcessName).Length > 1 Then
MessageBox.Show("Another Instance of this process is already running")
Application.Exit()
End If

Vijrag.

There's a nice solution for this in Chris Sells' book Windows Form
Porgramming in {C#|VN.NET}. You can get the code from his web site at
http://www.sellsbrothers.com/writing/wfbook/.
