纯Windows API 动态创建弹出菜单CreatePopupMenu 怎么响应?

[zhangwuji155]

	void OnRButtonDown(WPARAM wParam, LPARAM lParam)
	{
		int x = ((int)(short)LOWORD(lParam));
		int y = ((int)(short)HIWORD(lParam));
		POINT p = {x, y};
		ClientToScreen(m_hWnd, &p);

		//HMENU m = LoadMenu((HINSTANCE)GetWindowLong(m_hWnd, GWL_HINSTANCE), MAKEINTRESOURCE(IDR_MENU1));
		HMENU hMainMenu = GetMenu(m_hWnd);
		HMENU m = CreatePopupMenu();
		AppendMenu(m, MF_STRING, 1001, _T("1001"));
		AppendMenu(m, MF_STRING, 1002, _T("1001"));
		AppendMenu(m, MF_STRING, 1003, _T("1003"));
		AppendMenu(hMainMenu, MF_STRING | MF_POPUP, (UINT)m, _T("main"));
		
		TrackPopupMenu(m, TPM_VERTICAL|TPM_VCENTERALIGN|TPM_RETURNCMD, p.x, p.y, 0, m_hWnd, NULL);
	}

菜单可以显示出来,但点了没用,没有触发WM_COMMAND消息

响应WM_COMMAND消息，然后处理wParam和lParam 具体参数意义，请查看MSDN

你有添加和处理WM_COMMAND消息吗？

把参数中的 TPM_RETURNCMD 去掉， 就会有WM_COMMAND消息
