Hi. Actually i am almost done with my VB project, still have some problems. When i create an exe file, i am able to open any number of instances of my application. But i want only one instance.

So is there any code which will open the existing one instead of opening a new one. Some code which will disable more than 1 instance of the application. Please help me.

Thank you.

Use App.PrevInstance to see if a previous instance is already running.

Private Sub Form_Load()
' See if there is already and instance.
If App.PrevInstance Then
' Activate the previous instance
AppActivate App.Title

' Send a key (here SHIFT-key) to set the
' form from the previous instance to the
' top of the screen.
SendKeys "+", True

' Terminate the new instance
Unload Me
End If
End Sub

Thank you. It did work in the sense it doesnt open a second instance, but it shows an error saying

Runtime error 364
Object was unloaded

What should i do now? If u can tell me, plz do. For your information i wrote it in the splash scrren. I hope thats ok. Anyways Thanx a lot.

Try putting the code in the activate event instead of the load event. Does that help?

Thanx a lot. Writing it in the activate event worked fine without errors. Really.... thank you very much.
