Re: Printing multiple graphs on a page in C++

[User (Legacy)]

I found the following code to work.

 // TODO: Add your control notification handler code here

 int horres, verres, gap;

 long l, t, t2, r, b, b2;

 CDC MyDC;

 HDC hDC;

 CSize size;

 DOCINFO di;

 ::ZeroMemory (&di, sizeof(DOCINFO));

 di.cbSize = sizeof(DOCINFO);

 di.lpszDocName = _T("Sample two graphs per page");

 CPrintDialog dlg(FALSE, PD_USEDEVMODECOPIES | PD_NOPAGENUMS |

PD_HIDEPRINTTOFILE | PD_NOSELECTION, this);

 dlg.GetDefaults();

 hDC = dlg.GetPrinterDC();

 MyDC.Attach(hDC);

 gap = 42;

 /*

default Map Mode, MM_TEXT, pixels

*/

 horres = MyDC.GetDeviceCaps(HORZRES);

 verres = MyDC.GetDeviceCaps(VERTRES);

 l = 2*horres/3;

 t2 = t = gap;

 r = horres;

 b2 = b = (verres / 4);

 m_pChartFX1->Printer->Orientation = ORIENTATION_PORTRAIT;

 m_pChartFX2->Printer->Orientation = ORIENTATION_PORTRAIT;

 if (MyDC.StartDoc(&di) < 0)

  return;

 if (MyDC.StartPage() < 0)

  return;

 m_pChartFX1->Paint((long)hDC, l, t, r, b, CPAINT_PRINT, 0);

// adjust top and bottom for next graph

 t = b + gap;

 b = b2 - t2 + t;

 //  save references for next graph

 t2 = t;

 b2 = b;

 m_pChartFX2->Paint((long)hDC, l, t, r, b, CPAINT_PRINT, 0);

 // adjust top and bottom for next graph

 t = b + gap;

 b = b2 - t2 + t;

 // save references for next graph

 t2 = t;

 b2 = b;

 m_pChartFX3->Paint((long)hDC, l, t, r, b, CPAINT_PRINT, 0);

 // adjust top and bottom for next graph

 t = b + gap;

 b = b2 - t2 + t;

// save references for next graph

 t2 = t;

 b2 = b;

 m_pChartFX4->Paint((long)hDC, l, t, r, b, CPAINT_PRINT, 0);

 MyDC.EndPage();

 MyDC.EndDoc();
