VC 创建托盘，托盘tooltip。右键托盘菜单，点击别的地方会隐藏掉的问题。

托盘上的菜单右键弹出后，然后再别的地方，比如桌面，菜单无法隐藏掉，一直在托盘上，除非操作下菜单才能隐藏掉，只需要加上一句话

::SetForegroundWindow(m_nid.hWnd); 

就可以解决这个问题。

下面是托盘创建

class CXXXDlg
{

private:
NOTIFYICONDATA     m_trayid;        //作为托盘ID
};

//创建托盘
void CXXXDlg::CreateTray(HICON icon)
{
	m_trayid.cbSize = (DWORD)sizeof(NOTIFYICONDATA);
	m_trayid.hWnd = this->m_hWnd;
	m_trayid.uID = 128;
	m_trayid.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
	m_trayid.uCallbackMessage = UM_SHOW_THIRDBIND;
	m_trayid.hIcon = icon;

	wcscpy_s(m_trayid.szTip, _T("我是托盘"));
	Shell_NotifyIcon(NIM_ADD, &m_trayid);
}

//显示托盘tooltip
void CXXXDlg::ShowTrayTooltip()
{
    m_trayid.cbSize=sizeof(NOTIFYICONDATA);
    m_trayid.uFlags = NIF_INFO;
    m_trayid.uVersion = NOTIFYICON_VERSION;
    m_trayid.uTimeout = 5000;
    m_trayid.dwInfoFlags = NIIF_INFO;
    wcscpy_s(m_trayid.szInfoTitle, L"提示" );                  //气泡标题
    wcscpy_s(m_trayid.szInfo, L"我是托盘tooltip");             //气泡内容
    Shell_NotifyIcon( NIM_MODIFY, &m_trayid);
}

LRESULT   CXXXDlg::onShowTask(WPARAM    wParam,LPARAM    lParam)   //托盘响应消息     
{     
    if(wParam !=128)      
        return    1; 

    switch(lParam)       
    { 
    case    WM_RBUTTONUP:      
        {   

            ::SetForegroundWindow(m_nid.hWnd);                    //点击别的地方，托盘隐藏
            LPPOINT    lpoint=new    tagPOINT;     
            ::GetCursorPos(lpoint); 
            m_menu.GetSubMenu(0)->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON | TPM_RIGHTBUTTON, lpoint->x, lpoint->y, this); 
            delete   lpoint;
            break;
        }      
    case   WM_LBUTTONDBLCLK:   
        {     
            this->ShowWindow(SW_SHOW);
            SetForegroundWindow();
        }   
        break;     
    } 
    return    0;  
}
