>>Hello.

>>I am trying to figure out how many characters of a given font will print in a given page and printer. The EnumForms function of WinApi provides the width in thousandths of a millimiter for a given form and printer. The FONTMETRIC(6,,,) function of VFP gives the width of a character in pixels. In order to connect them I need the number of pixels that will be printed per unit of width. How can I get that?
