Printing without the Document/View framework
In order to keep the MFC doc/View feel I recomend providing helper functions OnBeginPrinting, OnEndPrinting and OnPrint similar to the CView versions. A CDC and a CPrintInfo object is passed into each of these functions. You will have to provide these functions yourself. Typically you would undertake any initialisation neessary (such as creating GDI objects) in OnBeginPrinting. Your OnPrint function would be where you do the actual printing/drawing, and your OnEndPrinting function performs any cleanup necessary (such as deleting GDIobjects created in OnBeginPrinting). You can call these functions whatever you want - I've used these names to be consistant with the CView names, and they are only used to show where the various initialisation/printing/cleanup code should be inserted by you.
void CMyDialog::Print()
{
CDC dc;
CPrintDialog printDlg(FALSE);
if (printDlg.DoModal() == IDCANCEL) // Get printer settings from user
return;
dc.Attach(printDlg.GetPrinterDC()); // Attach a printer DC
dc.m_bPrinting = TRUE;
CString strTitle; // Get the application title
strTitle.LoadString(AFX_IDS_APP_TITLE);
DOCINFO di; // Initialise print document details
::ZeroMemory (&di, sizeof (DOCINFO));
di.cbSize = sizeof (DOCINFO);
di.lpszDocName = strTitle;
BOOL bPrintingOK = dc.StartDoc(&di); // Begin a new print job
// Get the printing extents and store in the m_rectDraw field of a
// CPrintInfo object
CPrintInfo Info;
Info.m_rectDraw.SetRect(0,0,
dc.GetDeviceCaps(HORZRES),
dc.GetDeviceCaps(VERTRES));
OnBeginPrinting(&dc, &Info); // Call your "Init printing" funtion
for (UINT page = Info.GetMinPage();
page <= Info.GetMaxPage() && bPrintingOK;
page++)
{
dc.StartPage(); // begin new page
Info.m_nCurPage = page;
OnPrint(&dc, &Info); // Call your "Print page" function
bPrintingOK = (dc.EndPage() > 0); // end page
}
OnEndPrinting(&dc, &Info); // Call your "Clean up" funtion
if (bPrintingOK)
dc.EndDoc(); // end a print job
else
dc.AbortDoc(); // abort job.
dc.Detach(); // detach the printer DC
}
