convert an ole stdfont to a logfont structure:
with tlf
sfont = myfont.name
temp = strconv(sfont, vbfromunicode)
for ichar = 1 to len(sfont)
.lffacename(ichar – 1) = temp(ichar – 1)
next ichar
based on the win32sdk documentation:
.lfitalic = myfont.italic
lfweight = iif(myfont.bold, fw_bold, fw_normal)
.lfwidth = fontwidth
.lfheight = fontheight
.lfunderline = fontunderline
.lfstrikeout = fontstrikethrough
.lfcharset = myfont.charset
end with
hfnt = createfontindirect(tlf) convert the logfont into a font handle
test the font out:
hfntold = selectobject(hdc, hfnt)
drawtext hdc, mystr, -1, tr, dt_calcrect
offsetrect tr, 32, 32
drawtext hdc, mystr, -1, tr, 0&
selectobject hdc, hfntold
remember to delete the font when finished
deleteobject hfnt
