Page Layout...

MFC 4.1 Windows 95

--

I am investigating the possibility of writing an application to do page
layout for a particular kind of data.

Although I have written a couple of largeish applications using MFC, this
will be the first time that I have had to completely understand the MFC
document/view mechanisms.

The main requirement is that the application should immediately display a
scrollable view sized to the page size and orientation for the user's
default printer. It will show the page in the style of PageMaker/Quark
Xpress with a pasteboard style background.  This would allow the user to see
the entire page and a gray background surrounding the page. Items part on
and part off the "page" would only have the "page" part printed.

My questions are these:

1. How do I *SILENTLY* obtain the page size and orientation for the user's
default printer? 

Currently I am doing the following, which brings up a Page Setup Dialog,
whenever a new document is first created, which is what Quark Xpress does.
It's ugly and baffling to the new user though.

void CMyDoc::InitDocument(BOOL getPageSizeFromUser)
{
  if (getPageSizeFromUser)
  {
  	CPageSetupDialog pageDialog(TRUE);

  	// show the standard page setup dialog
  	pageDialog.DoModal();

  	LPDEVMODE pDevMode = pageDialog.GetDevMode();

  	if (pDevMode)	// this is the user's choice for this doc
  	{
  	  m_sizeDoc = pageDialog.GetPaperSize();
  	  m_Yresolution = pDevMode->dmYResolution;
  	}
  	else  	        // user has made no choice - default
  	{
  	  // default doc size - .001" in 8.5 x 11 page
  	  m_sizeDoc = CSize(8500,11000);

  	  // standard laser 300 dots per inch
  	  m_Yresolution = 300;
  	}
  }
  else
  {
  	...
  }
}

2. Has anyone else done all of this layout manager work?

Can I buy a pre-packaged class that abstracts out all of this?  I have no
real understanding of how hard this is.

Thanks for your time.

David

David,

Use the PSD_RETURNDEFAULT flag with CPageSetupDialog.
-----From: Kostya Sebov 

There's a Win32 bit flag, which sounds like PDS_RETURNDEFAULT, theat suppress UI
when you call CPageSetupDialog::DoModal().

You should combine this flag with corresponding CPageSetupDialog::m_psd
structure member variable somewhere between the construction of the dialog
object and the DoModal call. The rest of your code will work the same way.

Note that when this flaf is set CPageSetupDialog::DoModal returns IDOK in all
cases except there's no default printer, which usually means no printer at all.

Our company develops a line of products that handle PostScript's. I programmad
an application that allows you to scale/shift/orient an Image on the page berfore
it is printed.

Sincerely,

Checkout CPreviewView provided by MFC. You can find almost all answers.
-----From: Roger Onslow/Newcastle/Computer Systems Australia/AU 

BOOL CMyDoc::GetPageSize(CSize& size) {
 CPrintDialog dlg(FALSE);
 if (! ::AfxGetApp()->GetPrinterDeviceDefaults(&dlg.m_pd))  return FALSE;
 // GetPrinterDC returns a HDC so attach it
 HDC hDC = dlg.CreatePrinterDC(); ASSERT(hDC != NULL);
 CDC dc; dc.Attach(hDC);
 // Get the size of the page in mm
 size.cx = dc.GetDeviceCaps(HORZSIZE);
 size.cy = dc.GetDeviceCaps(VERTSIZE);
 // NOTE: use HORZRES/VERTRES for size in pixels
 return TRUE;
}

Talk to Stingray, they may well have something (I don't have any connection 
with them, but have seen ads for their MFC products)

Just do the follwing in your InitDocument() :

	LPDEVMODE pdv;
	CPrintDialog dlg(TRUE);

	dlg.GetDefaults();
	pdv = dlg.GetDevMode();

I think you know what to do next ...
