VC实现动态菜单的创建方法

//------------------ code begin ----------------//在类中定义的变量：// 双击托盘图标时对应的菜单项 id.UINT m_nDClickMenuItemId;// 弹出菜单句柄.m_hMenu m_hMenu;///动态创建右键菜单项.///@param item_text 菜单项文本字符串,以逗号分隔.///@param dbclick_id 双击托盘图标对应的菜单项id.// 调用示例:// create_menu("显示/隐藏,退出", 40001);BOOL CTrayIconMenu::create_menu(char* item_text, unsigned int dbclick_id){  m_nDClickMenuItemId = dbclick_id;  // 动态创建弹出菜单  m_hMenu = ::CreatePopupMenu();  if (m_hMenu == NULL) {    return 0;  }  int i=0;  int msgid=40001;  // 第一项菜单项的消息id.  BOOL ret = 0;  char * pText = ::strtok(item_text, ",");  while( pText != NULL )  {    ret = ::AppendMenu(m_hMenu, MF_ENABLED | MF_STRING, msgid + i, pText);    pText = ::strtok( NULL, "," );    i++;  }  return 1;}///响应消息显示菜单.LRESULT CTrayIconMenu::on_msg(WPARAM wid, LPARAM event){  // 一些其他处理代码...  POINT mouse;  ::GetCursorPos(&mouse);  // hWnd 为应用程序主窗口句柄.  if (event == WM_RBUTTONUP)  {    ::SetForegroundWindow(hWnd);    ::TrackPopupMenu(m_hMenu, 0, mouse.x, mouse.y, 0, hWnd, NULL);  }  return 1;}//------------------ code end ----------------
