Hi,
Today when i made an application using CBitmapButton?
i met this notification:
uses undefined class 'CBitmapButton'
Visual studio 2005 for pocket pc 2005 isn't supported this class.
What is the purpose of it?
JT
I tried to make a source code for CBitmapButton like below:
I tested, it run and can paste the Bitmap on the button, can
you test and fix the bug ( i test OK with LoadBitmaps )?
