Andrus,

I am not familiar with stunnel. If I do not know the class, I used to use two technics:
1. if I know the window caption, then
FindWindow(0,"WINDOW CAPTION") gives the handle, and then GetClassName API gives the class name.
2. often I use the utility API Spy by Derek Nicol, www.dwnldz.cjb.net, derek@dwnldz.cjb.net to see the needed information.

Regards. Though not George, but Yuri.
