How can I disable click through on my transparent form?

I'm using this procure to update my form when the user changes the slider. If they enable click-through by checking the checkbox, then click-through becomes active after changing the slider. The problem is that I can't find a way to disable click-through.

    Dim lOldStyle As Long
    Dim bTrans As Byte

    bTrans = sliderTrans.Value
   
    lOldStyle = GetWindowLong(Me.hwnd, GWL_EXSTYLE)

    If Me.chkClickThrough = False Then
        SetWindowLong Me.hwnd, GWL_EXSTYLE, lOldStyle Or WS_EX_LAYERED
    Else
        SetWindowLong Me.hwnd, GWL_EXSTYLE, lOldStyle Or WS_EX_LAYERED Or WS_EX_TRANSPARENT 'Click Through
    End If
   
    SetLayeredWindowAttributes Me.hwnd, 0, bTrans, LWA_ALPHA






If the user users Alt+Tab they can set focus on my application / form. Then if they press F10, it will uncheck click-through and run this code that doesn't work:


    Case vbKeyF10
            Me.chkClickThrough = False
            Dim lOldStyle As Long
            Dim bTrans As Byte
            bTrans = sliderTrans.Value
            lOldStyle = GetWindowLong(Me.hwnd, GWL_EXSTYLE)
            SetWindowLong Me.hwnd, GWL_EXSTYLE, lOldStyle Or WS_EX_LAYERED
   
            SetLayeredWindowAttributes Me.hwnd, 0, bTrans, LWA_ALPHA

If you look at your form in the design view and click inside the form, one option is Tab Order, you can remove access to any of the fields you choose.

I fixed the problem already. Logic bug:

Case vbKeyF10
  Me.chkClickThrough = False
  Dim lOldStyle As Long
  Dim bTrans As Byte
  bTrans = sliderTrans.Value
  lOldStyle = GetWindowLong(Me.hwnd, GWL_EXSTYLE)
  SetWindowLong Me.hwnd, GWL_EXSTYLE, WS_EX_LAYERED   '<----Removed lOldStyle
   
  SetLayeredWindowAttributes Me.hwnd, 0, bTrans, LWA_ALPHA
