[DotNetDevelopment] Windows Message Sample Code C#

[Ben]

I have no clue how to implement the sample codes. It uses Windows
Message, how do I go about getting this to work?

Sample code:


        public const Int32 WM_USER = 1024;
        public const Int32 WM_CSKEYBOARD = WM_USER + 192;
        public const Int32 WM_CSKEYBOARDMOVE = WM_USER + 193;
        public const Int32 WM_CSKEYBOARDRESIZE = WM_USER + 197;

        [DllImport("user32.dll", EntryPoint = "FindWindow")]
        private static extern Int32 FindWindow(string _ClassName,
string _WindowName);

        [DllImport("User32.DLL")]
        public static extern Boolean PostMessage(Int32 hWnd, Int32
Msg, Int32 wParam, Int32 lParam);


        Int32 hWnd = FindWindow("TFirstForm", "hvkFirstForm");
        PostMessage(hWnd, WM_CSKEYBOARD, 1, 0 ); // Show
        PostMessage(hWnd, WM_CSKEYBOARD, 2, 0); // Hide
        PostMessage(hWnd, WM_CSKEYBOARDMOVE, 0, 0); // Move to 0, 0
        PostMessage(hWnd, WM_CSKEYBOARDRESIZE, 600, 300); // Resize to
600, 300
