If a Form has a Button
and I click the Button
do the Form receive the WM_LBUTTONDOWN and WM_LBUTTONUP message first and
then pass it to the Button ???

actually i want to intercept the an user click to a particular Control on a
Form, where should i start working on?

thx

No. WM_LBUTTONDOWN and WM_LBUTTONUP goes to the button only
