Why this code not print anything??

[juanpast]

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.

	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.

Regards,
Pravin.

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.
