XNA程序开发常用到的一些代码汇总

This is the code form the menu system that starts the XNA game.


    var process = Process.Start(info);
    var currentProcess = Process.GetCurrentProcess();
    while (!process.HasExited)
    {
        Thread.Sleep(50);
        if (GetForegroundWindow() == currentProcess.MainWindowHandle)
        {
            Activate(process.MainWindowHandle);
        }
    }

This is the code that sets the XNA game as the foreground window.


        /// <summary>
        /// Sets the window to be foreground
        /// </summary>
        [DllImport("User32")]
        private static extern int SetForegroundWindow(IntPtr hwnd);
 
        /// <summary>
        /// Activate or minimize a window
        /// </summary>
        [DllImportAttribute("User32.DLL")]
        private static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
        private const int SW_SHOW = 5;
        private const int SW_MINIMIZE = 6;
        private const int SW_RESTORE = 9;
 
        /// <summary>
        /// The GetForegroundWindow function returns a handle to the foreground window.
        /// </summary>
        [DllImport("user32.dll")]
        private static extern IntPtr GetForegroundWindow();
 
        private static void Activate(IntPtr windowHandle)
        {
            ShowWindow(windowHandle, SW_RESTORE);
            SetForegroundWindow(windowHandle);
        }
