CDC: Fonts

[Geoffrey J. Corb]

How do you determine the width of a string (in say, 1/100 inch) using a
variable-width font? My problem is that I have a grid that I print-out that
has cells 3/8" wide. I am trying to print text into these cells, and center
the text within the cell. To do so, I figured I would have to determine the
width of the string and do the math. However, I cannot figure out how to
determine the width of the characters of the string, if the font is not
fixed-width. Currently, using a 9pt. Arial font, I *assume* the characters
to be 1/16" wide, which is accurate for most cases, except "i", "W", "M",
!", etc. etc. etc.

Thanks!

Geoffrey,

Have a look at GetTextExtentPoint32.

Use either the CDC::GetTextExtent() or CDC::GetOutputTextExtent() method.
These methods will return a CSize object containing the height and width of
the string. They simply use different DCs to compute the width. Look them
up in your online help. Also CDC::GetTabbedTextExtent() and
CDC::GetOutputTabbedTextExtent() may be useful. Also you could use the
CDC::DrawText() method and pass in the value DT_CALCRECT as part of the
format flags. This will set the passed-in rectangle to the size of the
string and will not actually draw the string.
