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;
}
