hi,

I have problem printing one bmp. Like said in the subject, everything is
perfectly OK on print preview, but then when printed, this image is missing.
What could that be?

void CEldataView::OnPrint( CDC *pDC, CPrintInfo *pInfo )
{
  CEldataDoc* pDoc = theApp.m_pDoc;
  ASSERT_VALID(pDoc);

  int katera_stran;

  if(pInfo->m_nCurPage > (unsigned int)vect_strani_za_tiskanje.GetSize())
    katera_stran = 0; else
  katera_stran = vect_strani_za_tiskanje[pInfo->m_nCurPage-1];

  CDC memDC;
  CBitmap bmp;
  bmp.LoadBitmap(IDB_ELDATA_LOGO);

  memDC.CreateCompatibleDC(pDC);
  memDC.SelectObject(&bmp);

  pDC->StretchBlt(500,200,3*382,3*80,&memDC,0,0,382,80,SRCCOPY);

//other stuff (which does get printed....) .........

ok, I realize now that I'll have to use StretchDIBits(...) instead:

I have trouble using it correctly, would someone please translate this code:

CDC memDC;
CBitmap bmp;
bmp.LoadBitmap(IDB_ELDATA_LOGO);

memDC.CreateCompatibleDC(pDC);
memDC.SelectObject(&bmp);

pDC->StretchBlt(500,200,3*382,3*80,&memDC,0,0,382,80,SRCCOPY);

Into code using StretchDIBits(...) instead of StretchBlt(...)

Please, please, please

Use LoadImage with LR_CREATEDIBSECTION to create a DIB section, instead of
DDB. Then attach to a CBitmap.

To use StretchDIBits, you have to load the bitmap as DIB.

I appologize for clustered postings, but I discovered something (not so?)
new again..

When I do this...
  pDC->SetMapMode(MM_ANISOTROPIC);
  pDC->SetWindowExt(1, 1);
  pDC->SetViewportExt(1, 1);

Is this equal of doing nothing at all?

My problem in the first place was that on some other printer (to which I
don't have access right now) page is printed with scale twice as big as
normal. I couldn't force MM_HIMETRIC to work good on my system, so I tried
MM_ANISOTROPIC like above. Will this fix my problem? I'm suspicious that it
won't, I think I'll have to get MM_HIMETRIC to work. Because thi mapping
mode uses milimeters in printer context and this should work all right for
all printers.

I'm quite desperate and I don't have time for experimenting, because I have
to learn for math exam :(
