How can I test for previous instance of the application?

[Helene Day]

I am looking for the equivalent of this VB code:

If App.PrevInstance Then

End if
Thanks,

Helene (I am still learning about .NET)

I don't know for sure what that code does, but if you're trying to make
sure that there's only one instance of the application running, see

I got it...

Function PrevInstance() As Boolean

If
UBound(Diagnostics.Process.GetProcessesByName(Diag nostics.Process.GetCurrent
Process.ProcessName)) > 0 Then

Return True

Else

Return False

End If

End Function

Well, that will tell you if there's another process with the same name.
It's always possible that there will be a completely *different*
process with the same name, of course. The chances of that kind of
clash happening are much lower with a named mutex, however.
