Fonts in OnBeginPrinting & OnPrint

Hello,

I've noticed that the CDC passed to OnBeginPrinting has a different font
than the one passed to OnPrint. Is there any way I can control this since it
has ramifications in my page calculation code. In OnBeginPrinting I walk a
list of strings and use CDC::DrawText() to calculate the rectangles they
draw into, caching them as I go. Later, in OnPrint(), I position the
rectangles and draw the text into them. But because the font changes, the
rectangles aren't accurate anymore so print preview displays things not as
they "should" be. I'd appreciate any suggestions that might get me past this.

Thanks in advance,

Easily fixed....
 Simply select the same font into both device contexts - never rely on the 
default font - I make this a cardinal rule in my own code.

    You mean GetTextExtent(), right?

[Moderator's note: No, he means DrawText().  Read the documentation and
look for the word DT_CALCRECT.]

    Do you  select in the  desired font,  (with which you  calculate the
"extents" in  OnBeginPrinting()) in OnPrint() (or  in OnPrepareDC()...)?
StartPage() (which the framework calls before the call to OnPrepareDC())
_resets_ the  DC attributes to _default_  values. So you need  to modify
the  DC attributes,  (if  you require  non-default  values, that  is...)
before rendering each page...

You have to create the font you want beforehand (or in OnBeginPrinting)
and select the font into the CDC in both places.

How about GetTextExtentPoint32()?, and use CDC::IsPrinting() to
determine what to do....
