It might be easier if somebody just shot me

[Lost User]

Back to my old chestnut of printing from a dialog based app. Got the text printing on a page using CDC::TextOut(), after setting the logical units to physical units using CDC::SetMapMode. What I want to be able to do is select the Font I am using to print, and determine the dimensions of a given string in that font using the same units so I can determine how many lines will fit on a page as well as a line. I can't find any of these functions in the online help, the MDI/SDI printing code generated doesn't help and I can't find any demos lying around the Internet on how to do this correctly from Dialogs. Can somebody help with an answer or a gun (I'm in Australia, if you read the thread in the Lounge earlier in the week you would understand.

Check out GetTextExtentPoint32() API function. I've a strong feeling this is what you need. -Shanker.

I haven't had chance to look at checking the text extent, but I think Shanker has helped there. The following example shows printing a title in centred, bold, 16 point, Times New Roman and then some other text left-aligned, 8 point, Courier New. The example is the message handler for a Print button on a dialog. Hopefully this should help with your font problem :)

void CPrintTestDlg::OnButtonPrint()
{
// Ask the user which printer they want to use
CPrintDialog dlg (FALSE);
if (IDOK != dlg.DoModal())
return;

CWaitCursor wait; // Show a busy cursor while printing

// Get the dialog to create a printer DC for this printer
HDC printerDC = dlg.CreatePrinterDC();

// Create a CDC connected to this HDC
CDC	dc;
dc.Attach( printerDC );

// Determine the printable area of the page
CPoint pt( GetDeviceCaps(dc.m\_hDC, HORZRES),
		   GetDeviceCaps(dc.m\_hDC, VERTRES) );
dc.DPtoLP( &pt );
CRect rectPage( 0, 0, pt.x, pt.y );

// Create the document information
CString strTitle = "Document Title";
DOCINFO docInfo;
docInfo.cbSize = sizeof(DOCINFO);
docInfo.lpszDocName = strTitle; 
docInfo.lpszOutput = 0; 
docInfo.lpszDatatype = 0;

// Start the doc and page
dc.StartDoc( &docInfo );
dc.StartPage( );

lstrcpy (pLogFont->lfFaceName, strFaceName);
