Is a question about M$ Visual C++ appropriate to this group?
I would like to know if there is any function (or whatever) that saves a
bitmap to a file. Something as simple as...
BOOL SaveBitmapToFile(CBitmap & cbmp, CString & filename);
In the program below, I copy the screen to a CBitmap [or I hope to;
I haven't tested it, since I can't write it to a file O:-)], but then
I can't write it to the file :-(

void MyView::OnFileSaveAs()
{
  CWnd *wnd = (CWnd *)this;     // necessary to get the CDC *
  CDC *pDC = this->GetDC();     // get CDC * associated to Window
  CDC pDC1;                     // other CDC
  CBitmap *old_bmp, new_bmp;    // bitmaps using MFC
  BITMAP bmp;                   // bitmap that doesn't use MFC
  if (pDC1.CreateCompatibleDC(pDC) == FALSE)
    return;     // error
  if (new_bmp.CreateCompatibleBitmap(pDC,
                     pDC->GetDeviceCaps(HORZRES),
                     pDC->GetDeviceCaps(VERTRES)) == FALSE)
    return;     // error
/* Select the bitmaps into the compatible DC. */
  if ((old_bmp = pDC1.SelectObject(&new_bmp)) == NULL)
    return;     // error
        /*
         * Copy color data for the entire display into a
         * bitmap that is selected into a compatible DC.
         */
  new_bmp.GetBitmap(&bmp);      // BITMAP is needed to get bm.information
  if (pDC1.BitBlt(0, 0, bmp.bmWidth, bmp.bmHeight,
      pDC, bmp.bmWidth, bmp.bmHeight, SRCCOPY) == FALSE)
    return;     // error
  // Start Dialog to create output file
  static char szFilter[] =
    "BMP File (*.bmp) | *.bmp ||";
  CFileDialog fdlg(FALSE, NULL, NULL, NULL, szFilter);
  CString name;
 if (fdlg.DoModal() == IDOK) {
   name = fdlg.GetPathName();
   SaveBitmapToFile(new_bmp, name);     // How can I do this???
 }
  pDC1.SelectObject(old_bmp);           // restore old object to save memory
