I'm a newbie on winapi stuff. Could you explain what do CBLPARAM, CBWPARAM, CBCTLMSG, CBHWND mean ?
I've run into this pseudocode and don't grasp it

Case WM_mousemove
if x>cblparam goto Exit
x=cblparam
 
What you're probably seeing is hungarian notation. It's a system of tacking on the datatype to the front of the variable name. So cblParam is probably a count of bytes to the lParam (which is itself a long value).

I would suggest you pick up a copy of Charles Petzold's book: Programming Windows fifth edition (ISBN: 157231995X).
