[RESOLVED] [02/03] Single Instance application on Vista

[GrimmReaper]

Hello everyone.
I'm used to doing this in VB.NET 2003:

If (UBound(GetProcessesByName(GetCurrentProcess.ProcessName)) > 0) Then
    MessageBox.Show("Already Running!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
    End
End If

Now, the purpose of the above code is to ensure that my application cannot be run twice, ie. a single instance application.
The above code works nicely on XP, but on Vista it produces the following exception:

An unhandled exception of type 'System.InvalidOperationException' occurred in system.dll

Additional information: Couldn't get process information from remote machine.

Any advice on how I can achieve the same effect on Vista too?
