This code checks for a previous instance of the program. This is not like the App.PrevInstance property. This checks the prevInstance no matter the location of the file, or the name of the app. You don't have to call DestroyWindow to destroy the created window, since when you quit the application, it is self destroyed. This may not work in the VB IDE, because the window is created by VB6.EXE. In this case you can call DestroyWindow in the Form_Unload().

This program checks for a previous instance of
the application. No matter where the exe is
located, it detects it. It is not like the
App.PrevInstance property.
It works by creating a "STATIC" window with a
specific code as the caption.
If the function finds the window containing
the code, then there is another instance
running.
You can change the InstanceCode for any string
you want.
You don't need to call DestroyWindow API, since
the window self destroys when the program is
closed.
