Question

Hey, I am using C# to try to send key commands to windows media center in windows 7.

Currently I can send keys like 4 and see the number 4 appears on the windows media center.

The problem is any key combination like Ctrl+p (to pause a movie) does not seem to have any effects on the media center.

Any help would be greatly appreciated. Here is my code snippet.

    // Get a handle to an application window.
    [DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
    public static extern IntPtr FindWindow(string lpClassName,
    string lpWindowName);

    // Activate an application window.
    [DllImport("USER32.DLL")]
    public static extern bool SetForegroundWindow(IntPtr hWnd);


    String HandleClass = "eHome Render Window";
    String HandleWindow = "Windows Media Center";

    private bool SendKeyCommand()
    {
        bool success = true;
        IntPtr PrgHandle = FindWindow(HandleClass, HandleWindow);
        if (PrgHandle == IntPtr.Zero)
        {
            MessageBox.Show(HandleWindow + " is not running");
            return false;
        }
        SetForegroundWindow(PrgHandle);
        SendKeys.SendWait("^p");
        return success;
    }

I was actually able to finally find a solution that worked on this website:

I ended up using his VK Class and Remote Sender Class methods to solve this problem. Windows media center must have lower level key hooks and you must implement a keyup/keydown sending solution to exploited the hooks.

I can finally pause a movie! I will clean up the code and post it later.
