I need to retrieve the System Font Size so I can scale the app to fit the screen. I have used GetSystemMetrics to find out the resolution of the screen and scaled accordingly but by using Large Fonts a screen can change its displayable area. I have coded for any screen size - the customer is using 1024*768 which is fine but they use Large Fonts which is 125% of normal fonts and so makes the app run out of the displayable area and having to scroll down and across to get to the OK button is not to good.

Any Help please
