Hi to all, I am subclassing an EDIT Control. But the WM_CREATE is not fired in Subclassed Procedure EditProc. What is wrong, i am unable to find. I had tried WM_NCCREATE also, but failed.
pls help.. http://www.barakasoft.com/script/Forums/Images/smiley_frown.gif http://www.barakasoft.com/script/Forums/Images/smiley_confused.gif
