I have a Windows 10 tablet. The screen automatically rotates if I turn the tablet sideways.
I'd like to be able to trigger screen rotation via code (preferably VB.Net.) Is this possible, and if so, how?
TIA

You may be able to do this with the ChangeDisplaySettingsEx API, by setting the dmDisplayOrientation accordingly. However, I note that the current documentation for the API doesn't mention being able to use DM_DISPLAYORIENTATION, when I feel sure it used to in the past - possibly because some display drivers didn't play the game properly.
Thx. I'm wondering if I can use the same method in VB.Net using "Include" statements?
The only examples are in C++.
There are examples of using it from C#, so those may be a starting point to convert to VB?
The examples don't include accessing "rotation" specifically though (and as you noted, "DISPLAYORIENTATION" also is not mentioned.)
And my ability to successfully translate VS C++ to VB.Net is probably lacking.
Thx
Before getting too far, check if my VidRes program can successfully rotate your display. If it can, then the ChangeDisplaySettingsEx method will work for you.
All it does is to add the DM_DISPLAYORIENTATION flag to dmFields, and for the 90 & 270 degree rotations, swap the dmPelsHeight & dm.dmPelsWidth values before calling ChangeDisplaySettingsEx.
This example in C# looks reasonable to me.
