Selecting text to clipboard from current active window.

I have a VB app that I have registered a hotkey with so that when i select Control & 1 my task is launched.The hotkey is working fine but I am unable to find how code my task to copy the selected highlighted text to the clipboard from the CURRENT active window.
I understand that ClipBoard.SetText Screen.ActiveControl.SelText can be used to capture the selected text from a form - but how do I get it to capture the selected text of the active window - whether it be highlighted text from a word document, web page or whatever text I have currently highlighted in any application currently.

Below is the code I am using ..

---- Codes in a BAS module
Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As Long, ByVal id As Long, ByVal fsModifiers As Long, ByVal vk As Long) As Long
Public Declare Function UnregisterHotKey Lib "user32" (ByVal hwnd As Long, ByVal id As Long) As Long
Public Declare Function GlobalAddAtom Lib "kernel32" Alias "GlobalAddAtomA" (ByVal lpString As String) As Integer
Public Declare Function GlobalDeleteAtom Lib "kernel32" (ByVal nAtom As Integer) As Integer
Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _
    (ByVal hwnd As Long, _
     ByVal nIndex As Long, _
     ByVal dwNewLong As Long) As Long
Declare Function BringWindowToTop Lib "user32" (ByVal hwnd As Long) As Long
Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Declare Function SetFocus Lib "user32" (ByVal hwnd As Long) As Long
Declare Function SetForegroundWindow Lib "user32" (ByVal hwnd As Long) As Long

Public Const SW_NORMAL = 1
Public Const GWL_WNDPROC = -4
Public Const WM_HOTKEY = &H312
Public Const MOD_ALT = &H1
Public Const MOD_CONTROL = &H2
Public Const MOD_SHIFT = &H4

Public lpPrevWndProc As Long
Public AtomID As Integer

Public Sub SubClass(ByVal hwnd As Long)
    lpPrevWndProc = SetWindowLong(hwnd, GWL_WNDPROC, AddressOf WindowProc)
End Sub

Public Sub UnSubClass(ByVal hwnd As Long)
    Dim lngReturnValue As Long
    If lpPrevWndProc Then _
        Call SetWindowLong(hwnd, GWL_WNDPROC, lpPrevWndProc)
End Sub

Function WindowProc(ByVal hwnd As Long, _
                    ByVal uMsg As Long, _
                    ByVal wParam As Long, _
                    ByVal lParam As Long) As Long
       
    If uMsg = WM_HOTKEY Then
        ClipBoard.SetText Screen.ActiveControl.SelText  'hotkey code
    End If
    WindowProc = CallWindowProc(lpPrevWndProc, hwnd, uMsg, wParam, lParam)

End Function

----Code in Form module
Private Sub Form_Load()
     AtomID = GlobalAddAtom("Atom1")
     Call RegisterHotKey(hwnd, AtomID, MOD_CONTROL, vbKey1)
     SubClass Me.hwnd
End Sub
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
    UnSubClass Me.hwnd
    Call UnregisterHotKey(hwnd, AtomID)
    Call GlobalDeleteAtom(AtomID)
End Sub

So to summarize my issue - I can copy selected text from a visual basic form into the clipboard but how do I copy the selected highlighted text from the screen from any application where I have selected text to the clipboard using my hotkey.

Many thanks in advance.
