Ok thanks for help but we have now make a dynamic scroll area so it uses minimal device context space, once again cheers]]> Mon, 20 Aug 2007 16:42:28 +0000 http://forum.codejock.com/forum_posts.asp?TID=7833&PID=25265&title=cxtmemdc-problem#25265 <![CDATA[CXTMemDC problem : Yeah we found that, but on 2000/XP/VISTA...]]> http://forum.codejock.com/forum_posts.asp?TID=7833&PID=25257&title=cxtmemdc-problem#25257 Author: terrym

Yeah we found that, but on 2000/XP/VISTA it is stranger as more inconsistant :)

Hello,

MSDN says

Windows 95/98: The created bitmap cannot exceed 16MB in size.

and nothing about 2000/XP.

We were working on a better solution but just wondered if there was a limited to size of bitmaps that one can allocate, as would be interesting to know :)]]> Mon, 20 Aug 2007 05:47:10 +0000 http://forum.codejock.com/forum_posts.asp?TID=7833&PID=25253&title=cxtmemdc-problem#25253 <![CDATA[CXTMemDC problem : Hello, I don&#039;t think you...]]> http://forum.codejock.com/forum_posts.asp?TID=7833&PID=25245&title=cxtmemdc-problem#25245 Author: Oleg

Hello,
 
I don't think you really need such big bitmap to draw. Think about how to optimize it and create smaller bitmap that only visible on screen.

I am using CXTMemDC to create a very large backbuffer which is 1503 by 15929 (32 bit colour) however it seems to have problems with this size, if I make a bit smaller it is fine ???
 
Is there a limit to the size of the:

m_bitmap.CreateCompatibleBitmap(m_pDC, m_rc.Width(), m_rc.Height());

command that CXTMemDC uses internally, eg. limit on memory, width or height ??
