If the font is not installed into windows then you can force windows to load the font by dropping it's file into your game/program folder and using the following two functions to load/unload the file so that you can access the font you want
function LoadFont(FontFile as string)
load dll "gdi32.dll", 1
result = call dll(1, "AddFontResourceA", FontFile)
delete dll 1
endfunction result
function UnloadFont(FontFile as string)
load dll "gdi32.dll", 1
call dll 1, "RemoveFontResourceA", FontFile
delete dll 1
endfunction
Warning: If your program ends without you calling the UnloadFont function then you will be unable to remove or move the font file until you reboot windows.
