Only one application should run

[MAK9974]

Hi guys.

I created an application in VB and created executable.

If i run one time its showing the form.
if i am running another time its showing
copy of another form.

What i need to do is, no matter how many times the exe is run (without closing the form), i need to run and show only one form and only one application.

can i do that?
-MAK

If you are using VB then you should be able to make an call to the API try checking out the API tips.

Found it.

If App.PrevInstance = True Then
MsgBox "Already One instance of briefcase is running."
End
End If
