What am I doing wrong. Any ideas ? Is there any other way to erase the background? Thanks Sabetay Perform(WM_ERASEBKGND , (long) Canvas->Handle, NULL); Back to top Sabetay Toros Guest Posted: Tue Jul 19, 2005 1:50 pm    Post subject: Re: WM_ERASEBKGND problem Sabetay Toros wrote: Quote: Hi, I'm sending a WM_ERASEBKGND message like the following but does not erase the background.

Actually it is erasing the background. The problem was with the components Paint function. Even if the Visible property is false it is painting. I'was thinking that if the Visible property is false will not call the Paint function.
