How to make OS update it's Display Properties->Settings Page

[indranil_m]

Hi,

I developed a small app that changes the Resolution of my desktop, say from 800x600 to 1024x768.
I am in 800x600 mode. I opened OS Display Properties->Settings page which shows under Screen Resolution 8x6. I chage the screen resolution to 10x7 using my app. But I still see in OS Settings page the Screen Resolution shows 8x6. How to make OS update this settings page?
Note: If I close the Display Properties-> Settings page, and re-open it, I can see that Screen Resolution is now 10x7.
But the resolution is not changing dynamically -- which I want to OS to do.

regards,
Indranil

tell your program to restart explorer.exe, that might do the trick...basically you have to force the computer to register current settings again, by just forcing a screen resolution change without consulting the OS, it doesn't know the resolution has been changed. Games do the same thing.
