How do I get my vb.net application to record touch screen events from Windows Mobile when it's not in focus?

I have a small program in Windows Mobile using VB.net that has a form (Form1) and and 2 list boxes (Listbox1, Listbox2). What I want to do is simply capture the X and Y coordinates of the stylus on touch screen events, and then put the X and Y coordinate values in their respective list boxes. Can this be done?

If at all possible I would like to find any examples, tutorials etc that show how to do this when the application is 1) in focus; and 2) not in focus. At minimum I would like to know how this is done while my form is in focus....but my main objective is to do this when my program is not in focus.

handle  MouseDown event which is fired with MouseEventArgs - these have X,Y coordinates where the stylus is tapped on the screen

oops, misread your question, so above is true when the window is in focus

Here is some code I found that runs error-free...but the code doesn't return anything yet...  how can I tap into it to get the x y values out... will this work for me? Where do I put my statement to return the coordinates? Thanks....

Private Shared Sub mouse_event(dwFlags As MOUSEEVENTF, dx As Integer, dy As Integer, dwData As Integer, dwExtraInfo As Integer)
End Sub

    MOVE = &H1
    ' mouse move
    LEFTDOWN = &H2
    ' left button down
    LEFTUP = &H4
    'left button up
    'right button down
    RIGHTUP = &H10
    'right button up
    'middle button down
    MIDDLEUP = &H40
    ' middle button up
    WHEEL = &H800
    'wheel button rolled
    VIRTUALDESK = &H4000
    ' map to entrire virtual desktop
    ABSOLUTE = &H8000
    ' absolute move
    TOUCH = &H100000
    ' absolute move
End Enum

Friend Shared Sub SendTap(x As Integer, y As Integer)
    mouse_event(MOUSEEVENTF.LEFTDOWN Or MOUSEEVENTF.ABSOLUTE, CInt(((65535 / Screen.PrimaryScreen.Bounds.Width) * x)), CInt(((65535 / Screen.PrimaryScreen.Bounds.Height) * y)), 0, 0)
    mouse_event(MOUSEEVENTF.LEFTUP, 0, 0, 0, 0)
End Sub
