how to find width of font?

I'm using directx to draw my string开发者_Python百科, directx uses GDI to draw the string..

I'm using DrawText to draw my string. I need a way to find the width of the string.

Any idea ?

You mean this DrawText? If so, it has a DT_CALCRECT flag that allows you to calculate the size of the text to draw.

DrawText can calculate it for you. See the DT_CALCRECT flag:
