1, in the resources of the icon to import a favorite icons, the ID named Idr_mainframe, the previous idr_mainframe icon removed;

2, in their own dialog header file defined a variable notifyicondata m_nid, about the structure of the specific information can be consulted MSDN;

3. Add the message response function OnInitDialog () and add the following code to the function, so that when the program starts, it displays its own application icon in the tray.

1   //---------------------------Tray Display---------------------------------//2 3M_nid.cbsize = (DWORD)sizeof(notifyicondata);4 5M_nid.hwnd = This-m_hwnd;6 7M_nid.uid =Idr_mainframe;8 9M_nid.uflags = Nif_icon | Nif_message |Nif_tip;Ten  OneM_nid.ucallbackmessage = Wm_showtask;//Custom message name A  -M_nid.hicon =LoadIcon (AfxGetInstanceHandle (), Makeintresource (Idr_mainframe)); -  thestrcpy (M_nid.sztip,"Server Programs");//Informational Cue bar is "server program", VS2008 Unicode Encoding with wcscpy_s () function -  -Shell_NotifyIcon (Nim_add, &m_nid);//Add an icon to the tray area

Compile at this time, will report Wm_showtask's mistake, because this message wants to define itself.

4. Declare the message function prototype in the dialog header file

LRESULT Onshowtask (WPARAM WPARAM, LPARAM LPARAM);

5. Message mapping in the dialog source file

On_message (Wm_showtask,onshowtask)

6, add a custom message response code in the dialog source file, left-click the pop-up application main window and right-click the pop-up menu.

1 LRESULT cserverdlg::onshowtask (WPARAM WPARAM, LPARAM LPARAM)2     {3            if(WParam! =idr_mainframe)4                   return 1;5            Switch(LParam)6            {7             CaseWm_rbuttonup://pop-up menu when right-click8                   {                9Lppoint Lpoint =NewTagpoint;Ten:: GetCursorPos (Lpoint);//Get mouse position One CMenu menu; AMenu. CreatePopupMenu ();//declaring a pop-up menu -Menu. AppendMenu (mf_string, Wm_destroy,"Close"); -Menu. TrackPopupMenu (Tpm_leftalign, lpoint->x, Lpoint->y, This); theHMENU HMENU =menu. Detach (); - menu. DestroyMenu (); - Delete lpoint; -                   } +                    Break; -             CaseWM_LBUTTONDBLCLK://left-click Processing +                   { A                           This->showwindow (SW_SHOWNORMAL);//Show main Window at                   } -  -                    Break; -            } -            return 0; -}

7, add OnSize message response function, handle the operation when minimizing.

 1  void  cserverdlg::onsize (UINT NType, int  cx,  CY)  2   { 3   Cdialog::onsize (NType, CX, CY);  4  if  (nType == size_minimized)  5   { 6  ShowWindow (sw_hide); //  7   8< /span>} 

8. Add the message response function when closing the window, remove the application icon from the Tray

1 BOOL Cserverdlg::D estroywindow () 2       3            // Remove icon in pallet area 4            Shell_NotifyIcon (Nim_delete, &M_nid);              5            return CDialog::D Estroywindow (); 6     }
