Parameters to CreateFont() have not effect

I’ve been trying to do outline font rendering on Windows and I’ve looked at nehe’s excellent tutorial and the superbible’s on the subject. When I put similar code into my project, I found I could not change the font height or width with the first two parameters of the API call CreateFont. (Superbible uses CreateFontIndirect.) Then I went back to the tutorials and found that changing variables in them has no effect either. Anyone know what is going on? (By the way, changing the font name–the last parameter–DOES work.)
