            重點
             1)取得句柄
                  
            pSystem->InitD3D((HWND)this->Handle.ToPointer());

             2)刷新畫面也跟Qt一樣靠定時器:拖個Timer(注意:默認是Enabled:false,改成true),雙擊下,改下面的函數
                 
                private: System::Void timerRender_Tick(System::Object^  sender, System::EventArgs^  e) {
                             
            if (pSystem)
                             {
                                 pSystem
            ->Render();
                             }
                         }

                   本來我是打Run的主意的
            Application::Run(gcnew MainForm());
            寫個類繼承自Application,然后override這個Run,在其中調用Render(),試了下,編譯出錯
            錯誤    1    error C3246: “EditorApplication”: 無法從“System::Windows::Forms::Application”繼承,因為它已被聲明為“sealed”    f:\Practise\Practise_2005\WorldEditor\WorldEditor.cpp    9    
            Application類不能被繼承!!!

            看了下xoyojank寫的 原創 DirectX in C++/CLI ,也用定時器好了。

            3)項目配置: 公共語言運行庫支持(/clr)    多線程調試 DLL (/MDd)

            這種方式是最好的?

            http://blogs.msdn.com/tmiller/archive/2005/05/05/415008.aspx

            My last post on render loops (hopefully)..
            The most common topic on my blog returns again. This time it will be brief as all I'm going to to do now is show you the render loop the June'05 SDK will be using. A coworker in another group came up with this markedly simple, yet deceptively effective loop for that groups projects. I liked it so much, i'm sharing it with everyone else. =)

            The basic loop (slightly modified from his original version and the version in the new SDK for ease of reading):

            public void MainLoop()
            {
            // Hook the application's idle event
            System.Windows.Forms.Application.Idle += new EventHandler(OnApplicationIdle);
            System.Windows.Forms.Application.Run(myForm);
            }

            private void OnApplicationIdle(object sender, EventArgs e)
            {
            while (AppStillIdle)
            {
            // Render a frame during idle time (no messages are waiting)
            UpdateEnvironment();
            Render3DEnvironment();
            }
            }

            private bool AppStillIdle
            {
            get
            {
            NativeMethods.Message msg;
            return !NativeMethods.PeekMessage(out msg, IntPtr.Zero, 0, 0, 0);
            }
            }


            And the declarations for those two native methods members:

            [StructLayout(LayoutKind.Sequential)]
            public struct Message
            {
            public IntPtr hWnd;
            public WindowMessage msg;
            public IntPtr wParam;
            public IntPtr lParam;
            public uint time;
            public System.Drawing.Point p;
            }

            [System.Security.SuppressUnmanagedCodeSecurity] // We won't use this maliciously
            [DllImport("User32.dll", CharSet=CharSet.Auto)]
            public static extern bool PeekMessage(out Message msg, IntPtr hWnd, uint messageFilterMin, uint messageFilterMax, uint flags);


            ------

            Simple, elegant, effective. No extra allocations, no extra collections, it just works.. The Idle event fires when there's no messages in the queue, and then the handler keeps looping continuously until a message does appear, in which case it stops.. Once all the messages are handled, the idle event is fired again, and the process starts over.

            現在見到這種方式,把控件invalidate了讓其重新繪制。

            Application.Idle += new EventHandler(form.Application_Idle);
            Application.Run(form);

            Invalidator.Shutdown();
            MFramework.Shutdown();
            }

            private void Application_Idle(object sender, EventArgs e)
            {
            if (this.Visible &&
            this.WindowState != FormWindowState.Minimized &&
            Form.ActiveForm == this)
            {
            Invalidator.Instance.Update(true);
            }
            }

            在控件的protected override void OnPaint(PaintEventArgs e)里繪制3D內容。  回復  更多評論

            Application::Idle -= idle;
