I am writing a graphics program that manipulates images from a large  
image file, which contains up to 16 images. I want to hardcode each
image into a bitmap (of size 256x256x16) and pass it to its private
child window to be displayed. 
I tried using SetProp and GetProp to pass the handle of the bitmap
to the child window, but the bitmap seems to be lost somewhere. The
bitmap, however, can be displayed normally on the parent window.
Does anybody has some idea what has happened ? I would really appreciate
any help.
