I have seen
SubclassDlgItem()
at http://functionx.com/visualc/controls/bmpbtn.htm

It mentioned "The suggestion is to "subclass" your button class so the messages sent to the bitmap button would be applied effectively."
I am not very clear with this statement...thus I go and find msdn
http://msdn.microsoft.com/en-us/library/0wx11zk9(VS.80).aspx
but still not very clear.

My question is what will be different if we include SubclassDlgItem() , and leave out SubclassDlgItem() ?
