This is a part of my program but it doesn't work. When I try to draw text by using 'TextOut', it gives a weird result. ( Very Big "Be" instead of "Bye") Do you know why it happens?

void CTestEmfView::OnLButtonDown(UINT nFlags, CPoint point)
{
      CMetaFileDC *pobjDC = new CMetaFileDC();
      CFileDialog dialog (FALSE, "emf", NULL,
      OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
      "Enhanced meta File(*.emf) | *.emf;||",  NULL);
      if ( dialog.DoModal() == IDOK )
      {
            pobjDC->CreateEnhanced(GetDC(), dialog.GetFileName(), NULL, NULL);
            OnPrepareDC(pobjDC);
            pobjDC->TextOut(0, 0, "Bye");
            HENHMETAFILE hpDC = pobjDC->CloseEnhanced();
            DeleteEnhMetaFile(hpDC);
      }
      CView::OnLButtonDown(nFlags, point);
}

Hi!
Can you create font and select them into the Metafile DC?

Of course, I tried it..(Created Font and selected it. )  but, it doesn't work. So, that's the problem.
I tried this code with visual c++ 6.0 also, and it worked. The difference between my visual c++ 5.0 and 6.0 is I installed visual c++ 5.0 by CD-Rom install Type.. I don't know why it happens.

If u give lpBounds as NULL, the graphics device interface (GDI) computes the dimensions of the smallest rectangle that can enclose the picture drawn by the application.

So set ur client dc as your attribute dc to the metafile dc.


void CTestEmfView::OnLButtonDown(UINT nFlags, CPoint point)
{
      CClientDC dc(this);
    CMetaFileDC *pobjDC = new CMetaFileDC();
    CFileDialog dialog (FALSE, "emf", NULL,
            OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
            "Enhanced meta File(*.emf) | *.emf;||",  NULL);
    if ( dialog.DoModal() == IDOK )
    {
            pobjDC->CreateEnhanced(&dc, dialog.GetFileName(), NULL, NULL);

            pobjDC->SetAttribDC(dc.GetSafeHdc());

            OnPrepareDC(pobjDC);
            pobjDC->TextOut(0, 0, "Bye");
            HENHMETAFILE hpDC = pobjDC->CloseEnhanced();

            pobjDC->ReleaseAttribDC();

            DeleteEnhMetaFile(hpDC);
    }
    CView::OnLButtonDown(nFlags, point);
}
