Why this code not print anything??

Code:

---

void CMAEC_SoftView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
        // TODO: add customized printing code here
        CBitmap bmpLogo;
        bmpLogo.LoadBitmap(IDB_BITMAP_LOGO);
       
        CDC dcLogo;
        dcLogo.CreateCompatibleDC(pDC);
        dcLogo.SelectObject(&bmpLogo);       

        pDC->BitBlt(0,0,bmpLogo.GetBitmapDimension().cx,bmpLogo.GetBitmapDimension().cy,&dcLogo,0,0,SRCCOPY);       
        dcLogo.DeleteDC();
}

Hello,

Get the bitmap dimension using BITMAP object. For that add the following lines in place of your line containing BitBlt call.

Code:

---

        BITMAP BM;
        bmpLogo.GetBitmap(&BM);
        pDC->BitBlt(0, 0, BM.bmWidth, BM.bmHeight, &dcLogo,0,0,SRCCOPY);

GetBitmapDimension will return the dimension of the bitmap in 0.1 mm units, which may not be the mapping mode of your printer DC.

Thanks Pravin, now I can see a black scuare in the print... some any idea why the result is a black scuare?

Very thanks for your reply.

Because when you print you must use DIB Bitmaps. (Device Independent Bitmaps)

Hi Luz.

And who can I change the resource bitmap to DIB bitmap??

Have a look at this FAQ. Is not the best example of coding but should work.
