As backgroud, a lot of windows related functions (also in API's) come in two tastes, so you're able to use them when you do/don't use unicode. You can set this in the project menu, project properties.

Also directx/windows application functions can have a ...ex version and a version without ex in the name. Mostly the one without ex does things for you based on some standard/ assumptions, the version with "ex" in the name gives you more control over different parameters the function needs/ uses.
