在内存dc里绘制图标怎么用bitblt传出来?

Question

CClientDC dc(this);
CDC dc1;dc1.CreateCompatibleDC(&dc); 
HICON hicon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_ICON1));
DrawIcon(dc1.m_hDC,0,0,hicon); 
GetDC()->BitBlt(0,0,32,32,&dc1,0,0,SRCCOPY);
结果没画出来
是不是不支持图标的传送啊?怎么才能传出来?

Answer 1

CClientDC dc(this);
CDC dc1;
HBITMAP hBitmap;dc1.CreateCompatibleDC(&dc); 
hBitmap = ::CreateCompatibleBitmap(dc1.m_hDC,32,32);
::SelectObject(dc1.m_hDC,hBitmap);HICON hicon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_ICON1));
DrawIcon(dc1.m_hDC,0,0,hicon); 
GetDC()->BitBlt(0,0,32,32,&dc1,0,0,SRCCOPY);::DeleteObject(hBitmap);

Answer 2

strchblt好像是这个函数会好些

Answer 3

就是，，直接DrawIcon就可以了

Answer 4

直接DrawIcon就可以了，也很快

Answer 5

dc.BitBlt(0,0,32,32,&dc1,0,0,SRCCOPY);
这样也可以啊 !
