You can use Process.GetProcessesByName(processName) to guess if there is
another instance running.

You can get the process name with
Syetm.Reflection.Assembly.GetExecutingAssembly.GetName.Name.

Dzemo,

See this page on our website, in my opinion the best implementation for
that.

I hope this helps,

Syetm.Reflection.Assembly.GetExecutingAssembly.GetName.Name.

This basically works, but note that the process name is not necessarily
unique.

Hi Cor,

Just curious, if the app crashes with an unhandled exception, is the mutex
released? Isn´t an exception handler needed?

Carlos,

I don't know however I could run this program as often as I did like.

\\\
Public Class myw
Public Shared Sub main()
MessageBox.Show("I am new alive")
Dim owned As Boolean
Dim mut As New System.Threading.Mutex _
(True, "xvcjsdf67AS124#$3", owned)
End
End Sub
End Class
////

I don't know a better method to kill a program
