Stylus tap position

I have made an application and the only GUI is an icon in tray. Im trying to popup a menu when the user click up to the icon but i can take the position of stylus tap. i dont want to make a tap and hold
Im trying the API GetCursorPos but its return an error that it tell that is unsupported for win mobile
According  the MSDN the LOWORD and HIWORD of event WM_LBUTTONDBLCLK  return the stylus position but the position tha return are wrong. Also im trying to use ClientToScreen API but still are wrong

Pleaze help!

That's the x and y from the click message:
x = LOWORD(lParam);
y = HIWORD(lParam);

It does work.

If you write an application for the system tray, you need Shell_NotifyIcon and you don't convert these coordinates.

here is my code that i use

the function OnTrayIcon from Message uCallbackMessage from NOTIFYICONDATA

LRESULT OnTrayIcon(UINT /*uMsg*/, WPARAM wParam, LPARAM lParam, BOOL& /*bHandled*/)
      {
            // Is this the ID we want?
            if (wParam != m_nid.uID)
                  return 0;
            T* pT = static_cast<T*>(this);
            // Was the right-button clicked?
            
            if (LOWORD(lParam) == WM_LBUTTONUP)
            {
                  // Load the menu
                  CMenu oMenu;
                  if (!oMenu.LoadMenu(m_nid.uID))
                        return 0;
                  // Get the sub-menu
                  CMenuHandle oPopup(oMenu.GetSubMenu(0));
                  // Prepare
                  pT->PrepareMenu(oPopup);
                  // Get the menu position
                  CPoint pos;
                  DWORD messagepos = ::GetMessagePos(); /*Here is my problem i cant take the stylus tap postition.I have already use LOWORD(lParam) and HIWORD(lParam) */
                 
                  pos.x = GET_X_LPARAM(messagepos);
                  pos.y = GET_Y_LPARAM(messagepos);
               

                  
                  // Make app the foreground
                  SetForegroundWindow(pT->m_hWnd);
                  // Set the default menu item
                  /*if (m_nDefault == 0)
                        oPopup.SetMenuDefaultItem(0, TRUE);
                  else
                        oPopup.SetMenuDefaultItem(m_nDefault);*/
                  // Track
                  oPopup.TrackPopupMenu(TPM_LEFTALIGN, pos.x, pos.y, pT->m_hWnd);
                  // BUGFIX: See "PRB: Menus for Notification Icons Don't Work Correctly"
                  pT->PostMessage(WM_NULL);
                  // Done
                  oMenu.DestroyMenu();
            }
 DWORD messagepos = ::GetMessagePos();
  WORD x = LOWORD(messagepos);
  WORD y = HIWORD(messagepos);

or, maybe:

pos = (CPoint(GetMessagePos()));

Use a trace/log utility to check the coordinates. They are correct and the problem can be somewhere in the menu. Check something simple like that:
::TrackPopupMenu(hMenu, 0, pos.x, pos.y, 0, hWnd, NULL);
::PostMessage(hWnd, WM_NULL, 0, 0);


Let's say that the problem is really in the coordinates. But this popup menu should jump in a more or less predefined position. At least for a test, use coordinates valid for your screen. If you will see the menu, so the reason was the coordinates as you suspected.

Hi

there is a great article at CodeProject about Notification Icons http://www.codeproject.com/KB/shell/StealthDialog.aspx 

Why do you need the tapped position, it is always within the Icon size. This notification icon is almost only 26x26 pixels. I dont see a need to track the clicked position for within the icon.
