Hi,
additional a guide for HotKeyNet can be found on this website in the software forum (or in my sig ).

From looking at your code, i would say it should work, if you manualy rename you windows to WoW1,WoW2,WoW3.
So for helping you out furthermore it would be nice if you could post the error messages (if there are any) that hkn shows.

Edit: sry, didn'T looked at hkn-site first, you did your problem resolved
