There might be something weird with the pause key, if you remove that and add a different key, does it work? ]]> RE: Cant Send CTRL+ALT+Pause to a Window https://www.displayfusion.com/Discussions/View/cant-send-ctrlaltpause-to-a-window/?ID=0191611a-10fa-771a-aff2-23c75bf75711#3 Mon, 19 Aug 2024 21:30:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cant-send-ctrlaltpause-to-a-window/?ID=0191611a-10fa-771a-aff2-23c75bf75711#3 DisplayFusion I tried using

Code
Copy
Select All

BFS.Input.SendKeys("%(^({VK_19}))");
but nothing happend.

other than using BFS.Window.Focus(windowHandle); is there a better way to ensure that is the target window getting the keystroke? If I hit the keys on the keyboard it works every time.

Thanks. ]]> RE: Cant Send CTRL+ALT+Pause to a Window https://www.displayfusion.com/Discussions/View/cant-send-ctrlaltpause-to-a-window/?ID=0191611a-10fa-771a-aff2-23c75bf75711#2 Mon, 19 Aug 2024 14:53:26 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cant-send-ctrlaltpause-to-a-window/?ID=0191611a-10fa-771a-aff2-23c75bf75711#2 DisplayFusion Try just running this line:

Code
Copy
Select All

BFS.Input.SendKeys("%(^({VK_19}))");

As a workaround I have modified my saved rdp file and added the value:

Code
Copy
Select All

smart sizing:i:1


With this value set, I can full screen the rdp window by pressing CTRL+ALT+PAUSE on the keyboard.
I am trying to automate this within a custom function but no matter what I have tried, I cannot send these characters to the window.

Function: Send CTRL+ALT+Pause

Code
Copy
Select All

using System;
using System.Drawing;

// The 'windowHandle' parameter will contain the window handle for the:
//   - Active window when run by hotkey
//   - Trigger target when run by a Trigger rule
//   - TitleBar Button owner when run by a TitleBar Button
//   - Jump List owner when run from a Taskbar Jump List
//   - Currently focused window if none of these match
public static class DisplayFusionFunction
{
    public static void Run(IntPtr windowHandle)
    {
        // your code goes here

        // Convert the window handle to hexadecimal
        string windowHandleHex = windowHandle.ToInt64().ToString("X");

        BFS.Window.Focus(windowHandle);

// Press and hold the Ctrl key
BFS.Input.SendKeyDown("Ctrl");
BFS.Input.SendKeyDown("Alt");
// ... perform any operations while Ctrl is held down ...
BFS.Input.SendKeys("{VK_PAUSE}");
// Release the Ctrl key
BFS.Input.SendKeyUp("Ctrl");
BFS.Input.SendKeyUp("Alt");
        
        
        //-- Send the CTRL + PAUSE keystrokes
//        BFS.Input.SendKeys("%^{VK_PAUSE}");
        //BFS.General.Sleep(500);
        //BFS.Input.SendKeys("^%{VK_PAUSE}");
        // ^ ctrl   % alt

        // Use the hexadecimal window handle in GetUserConfirm
        BFS.Dialog.GetUserConfirm("Current Hwnd " + windowHandleHex);

    }
}


As you can see from the above example I have tried both SendKeyDown and SendKeys, but neither are working for me.

Using the AutoIT spy tool I can verify I am setting focus on the correct window handle.

Any ideas as to what I am doing wrong?

Thanks. ]]>
