You may trap following messages to make the event:
WM_SETFOCUS
WM_KILLFOCUS

uhh, I used WM_KILLFOCUS and WM_SETFOCUS, but they didn't work, the code checked out, but when I focused on the thing the WM_SETFOCUS was aimed for, it didnt do jack, even tho i had code in the function. any help?
btw, I checked out all of the different beginner mistakes and the stupid stuff, and i've come to the conclusion that...I have no idea whats going on. except that i dont know how reliable the setfocus is, and maybe i associated it with the wrong object. im trying to use setfocus for a forum. Ill post the code up tommorow...Any suggestions? Cyprus

You may also try to use TWinControl's method of SetFocus or use folleing codes:
in header file:
protected:
void __fastcall WMFocus(TMessage &Message);
BEGIN_MESSAGE_MAP
MESSAGE_HANDLER(WM_SETFOCUS, TMessage , WMFocus)
MESSAGE_HANDLER(WM_KILLFOCUS, TMessage , WMFocus)
END_MESSAGE_MAP(TComponent)


in c file:
void __fastcall TYourComponent::WMFocus(TMessage &Message)
{
if(Message.Msg == WM_SETFOCUS)
//to do on set focus event
else
//to do on kill focus event
}


Happy programming!))
