Window handle and close window

Hello everybody,

I try to get a handle on a window which is popped up by a special remote library. The programm stops as long as I have pressed the O.K. button on the window. After this I would get the handle, but this is to late. I want to get the handle when the window pops up. I think threads could solve this problem but they don't exist in VB. Has anyone an idea how can I get the handle? I have to start two functions similary but how does it work?

Thanks and greetings, tksvc ;-)

You can do that using the CreateThread API which uses the AddressOF operator
