}
};

当然这也很简单，我们只要明白Flash的机制就可以了。后边是Flash播放的一些简单的处理

int APIENTRY _tWinMain(_In_ HINSTANCE hInstance, 
 
                      _In_opt_ HINSTANCE hPrevInstance, 
 
                      _In_ LPTSTR    lpCmdLine, 
 
                      _In_ int       nCmdShow) 
 
 { 
 
     UNREFERENCED_PARAMETER(hPrevInstance); 
 
     UNREFERENCED_PARAMETER(lpCmdLine); 
 
  
 
     // TODO: 在此放置代码。  
 
     HRESULT hr =  CoInitialize(NULL); 
 
     AtlAxWinInit(); 
 
  
 
     MSG msg; 
 
     HACCEL hAccelTable; 
 
  
 
     // 初始化全局字符串  
 
     LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING); 
 
     LoadString(hInstance, IDC_WIN32PROJECT7, szWindowClass, MAX_LOADSTRING); 
 
     MyRegisterClass(hInstance); 
 
  
 
     // 执行应用程序初始化:  
 
     if (!InitInstance (hInstance, nCmdShow)) 
 
     { 
 
         return FALSE; 
 
     } 
 
  
 
     hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_WIN32PROJECT7)); 
 
  
 
     // 主消息循环:  
 
     while (GetMessage(&msg, NULL, 0, 0)) 
 
     { 
 
         if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) 
 
         { 
 
             TranslateMessage(&msg);
