Refresh rates

[radagastX]

My current resolution is set to 800x600, 16bit.
In a game that im making, i change the resolution to 640x480, 16bit.

The problem lies in changing the resolution back to the original 800x600, 16bit. The refresh rate gets all screwed up when changing back.

I need to know how to access the refresh rate. Whats the API call?

I believe you must just pass 0 with it as the refresh rate. That lets windows sort it out based on the default (Display -> Settings -> Advanced)
