Creating a bitmapped button...???

Hi all, I''ve used Ms Visual Studio 6 to create a dialog. On the dialog I placed some buttons, but I want to display bitmaps on the buttons (I already checked the "bitmap" checkbox). I found some tutorials but they all use MFC :-(. Can somebody explain me how to do this ?? Oh yeah, I would like to change the bitmaps "on the fly". Another thing, does someone know what kind of button I have to use, if I want to have the same "effect" as the bold, italic,...buttons in Word ??? You know, a button that stays "pushed" until you "unpush" it :-) Thanks !!
