Hi there,

	In our project we are extensively using  bitmap buttons. We have =
provided hot keys 	for all buttons such as Alt-c for Cancel. For each =
bitmap button, there is a static field
	which will explain the functionality of the button and it's hot key. So =
the text in=20
	the static control will expalin the hot key and when the key is pressed =
it will go=20
	to the specific button message handler.

	V have impelmented it in following way..

	We are using AutoLoad function for loading bitmap button. So in the =
button caption
	and bitmap name we are preceding & before the actual character such as=20
	&CANCEL for cancel button. and for static controls , instead of using=20
	SetWindowText we are using DrawText after getting device context of the =
static
	control for setting the text alongwith the hot keys like "&Cancel".=20

	This implementation works. But it's behaviour is very unpredictable. =
Sometime it=20
	gives GPF in user.exe or gives assertion in wincore.cpp line 208. This =
also works
	for the views and dialogs which do not have accelerators.=20

	So will somebidy help me ?? Am I doing anything wrong?? Is there any =
other better
	solution ??
