Setting my Display Resolution

Question

Hi,

I'm a C# developer and I have to change my display resolution regularly.

There are plenty of examples on how to read the current display resolutions: SystemInformation.PrimaryMonitorSize

I found the ChangeDisplaySettingsEx Function

Is the only way to do this in C# is with PInvoke???

It seems odd to me that it is very easy to get this information out, but difficult to set it...

Answer 1

You'll have to make a PInvoke call to ChangedisplaySetting.

Here's a link that has some sample code, http://www.xtremedotnettalk.com/printthread.php?t=73184.

Answer 2

I also recommend that you check out Jared Parsons PInvoke Toolkit. You can download it here:

http://www.codeplex.com/clrinterop/Release/ProjectReleases.aspx?ReleaseId=14120

It makes adding pinvoke signatures to your code a breeze. It doesn't always pick the right interop types, but it's usually pretty close, and even if you have to make some changes its still usually quicker than translating everything by hand.

Answer 3

Simple answer: Yes. You should use PInvoke.
