Hi
Does anyone have the code or maybe give me a start on how to detect if my
program is already running if someone tries to run it again while it's already
running? I know I could do this with a dummy file by putting something in the
file while it's running and emptying the file when it's not running, but I was
hoping for something a little more professional. Has anyone done this yet?

You could try something like...

-- Code starts --
If
Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName).Length >
0 Then
' exit application or display message
End If
-- Code ends --

Hope this helps.

This one works too, and I think it's the preferred one. Thanks for
making me aware of that.

Notice that the application name isn't necessarily unique.

Note that this code will detect it self. It should stand .Length > 1.
BTW ProcessName is not necessary unique.
