hi, I have read the gui tutorial on this site(developing a gui using c++ and dx..) but there is something I didnt understand bout the textboxes. its written that I have to draw "caret" according to the lenght of my text, but some characters are wider than others how can I predict how much pixel I have to go "right".I mean these two strings wont be taking the same space. "iiiiii" "oooooo"

sorry for my ignorance but I didn't understand what you mean. I googled "CALLCRECT directx" but i couldn't find anything.
