Changing screen resolution by program

[manjut19]

Hello Experts,

I have made a Win32 GDI Application which runs only in 1024*768 Resolution.
When the application runs on any other resolution, drawings gets disturbed,So i want to restrict the resolution to 1024*768 through program.How to set the resolution to this pixel ,Can i use ChangeDisplaySetting() function to set to a specific pixel?

Why don't you want to fix your code to draw correctly in any other resolution instead?

Can i use ChangeDisplaySetting() function to set to a specific pixel?

Why don't you want to try it?
Note however, that it only changes the settings of the default display device! To change the settings of a specified display device, use the ChangeDisplaySettingsEx function.

The majority of people won't like your program if it messes around with the desktop resolution.
it'll also look bad on any LCD screen that doesn't have 1024x768 as native resolution.
it could cause problems if the screen doesn't even support that resolution.


As victor said... Fix your app to work properly in any resolution
if you really need to enforce a resolution, you could consider fullscreen directX, but then you can't use the GDI.

For one thing, 1024x768 is so yesterday. Any store bought computer out there doesn't run that low of resolution.

As others have mentioned, changing a user's resolution is a bad idea.

It's much better (and more professional) to fix your program so it runs under different resolutions.
