How to make my application DPI-aware?

When a user sets the DPI scaling to draw fonts and windows larger in all displays, I don't want my application to be affected (I don't want my application's fonts and controls get larger)

I tried to use SetProcessDPIAware() function or add a manifest file, but it didn't work. How can I prevent windows (XP, 7 and 8) to change my application's font size?

Current medium-high resolution screens are already causing users to complain "Text is miniscule! Menus are unreadable!" for badly written interfaces. Imagine >300dpi screens, 'coming soon'. It begs the question, why would you want this? - Jongware

You're asking the wrong question. You want it to be DPI-independent. The answer is to size everything in points, and everything relative to that in ems. Avoid DPI and pixels completely.
