Program already running

[Guest]

How would one check to see if a program is already running? I don't want my
app to be launched more than once.

Thanks,
Mark

How would one check to see if a program is already running? I don't want
my
app to be launched more than once.

How do I make sure that only one instance of my application runs at a time?

#Region "Previous Existance (FUNCTION)"

Private Function PrevInstance() As Boolean
If
UBound(System.Diagnostics.Process.GetProcessesByName(System.Diagnostics.Proc
ess.GetCurrentProcess.ProcessName)) > 0 Then
Return True
Else
Return False
End If
End Function

#End Region

Usage:
--------

If PrevInstance() = True Then
MessageBox.Show("Application is already running")
End ' Must call end & not 'Application.Exit()' here
End If
