I have a problem to SelectObject of Bitmap into memery DC. My code is like,
Code:
HINSTANCE hinstOriginal;
hinstOriginal = ::AfxGetResourceHandle();
::AfxSetResourceHandle(g_hResInstance);
CDC mem;
CBitmap *oldBmp;
CBitmap temp;
BOOL B = temp.LoadBitmap(id); //id is resource id
BITMAP BitMap;
temp.GetBitmap(&BitMap);
mem.CreateCompatibleDC( pPrintDC ); // a printer DC
mem.SetMapMode (pPrintDC->GetMapMode ());
oldBmp = mem.SelectObject(&temp); // this call returns 0 on some PCs!
CPoint size;
size.x = BitMap.bmWidth;
size.y = BitMap.bmHeight;
mem.DPtoLP(&size);
BOOL bret = pGDoc->m_pDC->StretchBlt(m_iX,
m_iY*-1,
m_iWidth,
m_iHeight*-1,
&mem,
0,
0,
size.x,
size.y,
SRCCOPY);
This code works on same PC, but not on others, SelectObject returns 0;
Please help.
Thank you very much.
