Hello Community,
I need help with this script, i can't seem to use this to switch beteen dll files that contain a form eg. if i use it to open a form from the dll file called "Dll One" then when i click the button again it still opens the form from "Dll One", but i want it to open the form from a dll file called "Dll Two".

(I have uploaded the form)

Please Help...
