Comments
This method gives classes derived from SECOwnerDrawButton the chance to initialize the screen and memory DCs before any drawing takes place. All drawing is done to a memory (off screen) DC to reduce flicker. If there was a problem creating the memory DC, then pMemDC will be the same as pScreenDC.See Also
