RFI: Win32 API or WMI means of manipulating multiple video displays/monitors.

I think ultramon let's you set up different profiles like this and switch between them.

Ralf Maximus:

There are two classes inside the .zip: Monitors.cls is the main control structure & procedures, while Monitor.cls is the object definition for the collection.  Reading thru the code suggests it does not accept new values; it's just providing data about the video configuration.  So in that regard it's not helpful, but still it might yield a clue.  The API calls utilized are:


Basically upon initialization you end up with a collection of individual Monitor objects, one for each enumerated display.  You can determine just about everything from individual height + width to the total desktop real estate available.

I did not include a referenced file, MonitorPickerForm, as it's a simple graphical display showing the orientation/position/size of each monitor object, similar to your screenshot but cheesier.  Since you're not planning to compile this I figured it's not important.

Wish it was more,

Aye, that it does.

Is there anything UltraMon doesn't do?  Oh yeah... get along with nVidia Desktop Manager. 

Yeah, Ultramon will let you do it as easily as double-clicking on the systray icon (if you configure it for that action).  Plus you get a lot of other really nice multimonitor functions to boot.

My laptop actually handles this automatically when I plug/unplug the monitor signal cable.

Thanks Ralf, but I got the stuff I need to retrieve the info. I need the info to set it. But thanks to you guy mentioning UltraMon, I now have another place to look for help. UltraMon has a freely downloadable SDK with a help file and sample code. They require a licensing fee if you use their COM controls, but maybe I can find the few API calls I need in there somewhere.

If it is OK with you Mouser, maybe you can contact them and see if we can get a license that allows us to release Donationware (like Coding Snacks) at no cost.
