Answer 1

if   (!menu.LoadMenu(m_ctiTrayIcon.m_tnd.uID))   
return   0; 
if   (!(pMenu   =   menu.GetSubMenu(0)))   
return   0; ::SetMenuDefaultItem(pMenu-> m_hMenu,   0,   TRUE); CPoint   pos; 
GetCursorPos(&pos); 
::SetForegroundWindow(m_ctiTrayIcon.m_tnd.hWnd);     
::TrackPopupMenu(pMenu-> m_hMenu,   0,   pos.x,   pos.y,   
0,   m_ctiTrayIcon.m_tnd.hWnd,   NULL); 
menu.DestroyMenu(); 

Answer 2

SetForegroundWindow主要就是这个函数

Answer 3

在你弹出菜单之前，设置你的窗口为最前窗口，代码如下：POINT   p; 
GetCursorPos(   &   p   ); //   Increase   the   thread   priority   by   invoking   SetForegroundWindow. 
SetForegroundWindow(); //设置窗口在最前面m_Menu.TrackPopupMenu(   TPM_LEFTALIGN   |   TPM_RIGHTBUTTON,   p.x,   p.y,   this   ); 
    4）调用TrackPopupMenu()之前，你必须先调用SetForegroundWindow(   m_hWnd   )，然后调用PostMessage(   m_hWnd,   WM_NULL,   0,   0   )：                   POINT   point; 
                  GetCursorPos(   &point   ); 
                  SetForegroundWindow(   m_hWnd   ); 
                  TrackPopupMenu(   hPopup, 
                        TPM_RIGHTALIGN   |   TPM_LEFTBUTTON   |   TPM_RIGHTBUTTON, 
                        point.x, 
                        point.y, 
                        0, 
                        m_hWnd,   0   ); 
                  PostMessage(   m_hWnd,   WM_NULL,   0,   0   );
