simulating mouse click on the warcraft3 button using win api
===

I wonder if it possible to get handle of any button of the warcraft 3 game? Tried to get it via spy++ and Control Viewer but there only main WC3 window is availible.  
So any ideas or suggestions?  
  
I'm trying to simulate click on the button. I think it is possible to do this using coordinates of the button, but i'm not sure if it possible to calculate such a coordinates for all the screen resolutions. If I mistaken somewhere - please, correct me!
  
Thanks everybody in advance!
