在线结贴，关于托盘菜单的问题！

Question

右键单击托盘后，弹出一菜单，关闭不了，只有选择某一项或在程序窗口内单击鼠标是才能关闭菜单，为什么会这样？
下面是部分程序：
else if(lParam==WM_RBUTTONDOWN)//鼠标右键单击弹出菜单
{ 
CMenu menu;
menu.LoadMenu(IDR_APP_MENU); //载入事先定义的菜单

CMenu* pMenu=menu.GetSubMenu(0);
CPoint pos;
GetCursorPos(&pos);
pMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,pos.x,pos.y,AfxGetMainWnd(),NULL);
::PostMessage( m_hWnd, WM_NULL, 0, 0 );
pMenu->DestroyMenu();
}

Answer 1

将AfxGetMainWnd()改为NULL或者GetDesktopWindow()试试。

Answer 2

pMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,pos.x,pos.y,AfxGetMainWnd(),NULL);
::PostMessage( m_hWnd, WM_NULL, 0, 0 );
 ~~~~~~~~~~~~::SendMessage看看
pMenu->DestroyMenu();

Answer 3

改为this也不行。有没有例子可以参考呢？

Answer 4

case WM_RBUTTONDOWN:
POINT point;
               HMENU hMenu, hSubMenu;
               // Get mouse position
               GetCursorPos(&point);
               // Popup context menu
               hMenu = LoadMenu(hInst, MAKEINTRESOURCE(IDR_MYMENU));
               hSubMenu = GetSubMenu(hMenu, 0);
               SetMenuDefaultItem(hSubMenu, IDM_DEFAULTCMD, FALSE);
               SetForegroundWindow(hMainDlg);         // Per KB Article Q135788
               TrackPopupMenu(hSubMenu,
                  TPM_LEFTBUTTON|TPM_RIGHTBUTTON|TPM_LEFTALIGN,
                  point.x, point.y, 0, hWnd, NULL);
               PostMessage(hMainDlg, WM_NULL, 0, 0);   // Per KB Article Q135788
               DestroyMenu(hMenu);

Answer 5

终于找到了例子：VCKBASE 上的Helptip
在GetCursorPos(&pos);侯加
::SetForegroundWindow(nid.hWnd); //nid为托盘结构体
谢谢大家的参与！
