I have a service that is running on a VM running Windows and I need to determine if the VM window is running full screen. Is this possible?
I have already tried investigating the following without success:
[DllImport("user32.dll")]
static extern IntPtr GetDesktopWindow();
[DllImport("user32.dll", SetLastError = true)]
static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetWindowRect(HandleRef hWnd, out RECT lpRect);
var expStyle = GetWindowLong((IntPtr)5160, (int)GWL.GWL_STYLE);
var result = GetWindowRect(new HandleRef(GetConsoleWindow(), GetDesktopWindow()), out rect);
Hi,
Are you rdp to the VM?
is the VM on hyper-v?
Yes, I'm using the "Remote Desktop Client" to connect from my computer to the VM. MSRDC downloaded from: https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/windowsdesktop#install-the-client
The VM is simply an Azure VM... don't know the underlying host.
My goal is to detect if the user minimizes or changes the size of the VM RDP window. Another alternative is to disable the sizing buttons.
I'm wondering could we define the properties in RDP file so that users cannot change the window size.
Yes, that would be great! Our requirement is to either be able to determine when the window is resized or not allow them to change the size. Thank you!
One more thing to mention; the RDC client doesn't use an RDP file, it uses a URL.
The rdp file is download through Mstsc, after you entered the credentials of the remote computer.
After download, we could modify the values in the rdp file according to this article: Supported Remote Desktop RDP file settings
Thank you so much for your reply. I read through the options of the RDP file and found 2 that could possibly apply:
keyboardhook:i:value and screen mode id:i:value
Do you know if either of these or any of the others prevent the user from minimizing or resizing the remote desktop window?
Thank you.
I think that would be screen mode:
Thank you again!!!
I was able to find the downloaded rdp file in "AppData\Local\rdclientwpf\0201594c-0399-4f6b-9650-66c4c4e4245c>1c4f61a9-430f-469e-a5e6-08d8f73e37d0.rdp".
I made the modification by adding "screen mode id:i:2". When I try to use the RDP file I'm getting the following error:
I assume the order of the settings don't matter. Any idea what might be wrong? The file appears to have hash values at the end.
If you don't modify and connect with rdp file directly, is there any error messages?
Same error.
I also created another non-feed VM in my azure subscription and made the same modification and unfortunately I'm able to minimize the VM window.
Hi,
I also did a test, and found configure the value of screen mode to 1 or 2 , both can minimize the screen. Apologize to waste your time on this.
@Karlie Weng , I'm guessing there is no way to prevent the window from being minimized.
Thank you for all your assistance.

Hello David,
I guess modify rdp file cannot realize this feature. This may still need the help with some code.
You could try post this in Stack Overflow which is an open community for anyone with codes.
Best regards
Karlie
