Hi, You need to type cast the expression to float like the following: float aspectRatio = (float)1280 / 1024; MessageBox.Show(aspectRatio.ToString()); Or float aspectRatio = (float)1280 / 500; MessageBox.Show(aspectRatio.ToString()); This will fix the issue. Regards, John Adams ComponentOne LLC

That would be why :) Knew it had to be something stupid. Thanks mate.

This is an example of what I've done, just in case anybody else needs something similar in the future. Cheers for your help guys. FileCopyTest.zip[^]

I was going to do that (retrieve the file types' icon and then just add my image to it) but I've never played with OwnerDraw before and thought I'd give it a go. This is only a personal project so I've got the time to learn a few new bits.
