I have just signed up for this new board so lets see if can get any replies for this.
I have the following code in Microsoft Visual C++ 6.0
BitBlt(dc->m_hDC, 0, 0, 400, 400, memDC.m_hDC, 0, 0, SRCCOPY);
and it outputs nothing. I belive this is because the memDC does not have a size. If i just paint the tmpDC like this:
BitBlt(dc->m_hDC, 0, 0, 400, 400, bmpDC.m_hDC, 0, 0, SRCCOPY);
it works fine. Do you know i can fix my problem?
