There is no way to do that with OpenGL, you have to calculate it on your own using GDI functions.
GetTextExtent(Ex) might be of some help.

Also remember that an outline font does not have a "pixellength" it's just a set of polylines or triangle(strips/fans), so the length depends on how you display it in OpenGL to.

I think you are correct,but what do mean by "so the length depends on how you display it in OpenGL to",it means the lenght is equal to starting co-ordinates of text to end co-ordinates of text in OpenGL Co-ordinate system after that I have to calculate the pixellenght by pixel mapping?
