Forcing landscape orientation

How can I force Print Preview  to show a particular view in landscape orientation without user intervention?
(and Print to print it, naturally!)

Dllocate a device mode structure (DEVMODE) and indicate that the dvice is in landscape mode.
Print is just working with a print DC in the same way.

If you use MFC ,Use a CPrintDialog:

CPrintDialog PrintDialog(FALSE);
   
 
AfxGetApp()->GetPrinterDeviceDefaults(&PrintDialog.m_pd);

DEVMODE  FAR *lpDevMode  = (DEVMODE  FAR *)  
::GlobalLock(PrintDialog.m_pd.hDevMode);
//set mode
lpDevMode->dmOrientation = DMORIENT_LANDSCAPE;
 
::GlobalUnlock(PrintDialog.m_pd.hDevMode);

Then create a CDC and attach with PrinterDC:
  CDC DC;
  DC.Attach(PrintDialog.GetPrinterDC());
 
//Then set the document info
  DOCINFO di;
  CString strTitle;
  memset (&di,0,sizeof(DOCINFO));
  strTitle.LoadString (AFX_IDS_APP_TITLE);
  di.cbSize = sizeof(DOCINFO);
  di.lpszDocName = strTitle;
  strTitle.Empty();

//start the actual printing
  DC.StartDoc (&di);
  DC.StartPage ();

 
//printing here.....
DC.TextOut();

.......detach latter.

Here is working code to set landscape mode:

PrintDialog.m_pd.hDevMode = ::GlobalAlloc( GHND, sizeof(DEVMODE) );
  DEVMODE * devMode = (DEVMODE *) ::GlobalLock(     PrintDialog.m_pd.hDevMode );
  devMode->dmSize = sizeof(DEVMODE);
  devMode->dmOrientation = DMORIENT_LANDSCAPE;
  devMode->dmFields = DM_ORIENTATION;
  ::GlobalUnlock( devMode );

For Wyn.
The first 7 lines of your 4.40 (first) answer did the trick wonderfully well.
Thanks, Mike Gordon.
