When Controls overlap

[Zmcpherson]

Alright my goal is to test to see if the user has dragged a label over a button. I have add event handlers for MouseMove and ButtonEnter, the trick is that i dont want the buttonEnter sub to fire unless the user is actually dragging a label.

Dim dragging As Boolean = False
 
   Public Sub Label_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
        Static lOffset As Point
        lbl = DirectCast(sender, Label)
        If e.Button = MouseButtons.None Then
            lOffset = New Point(e.Location)
            dragging = False
        ElseIf e.Button = MouseButtons.Left Then
            lbl.Location = lbl.Location + e.Location - lOffset
            dragging = True
        End If
    End Sub
 
    Private Sub Button_MouseEnter(sender As System.Object, e As System.EventArgs)
        If dragging = True Then
            MsgBox("This is a Test")
        End If
    End Sub

I thought would work but because the user is dragging the label the mouse never actually enters the button field.

I also tried doing lbl.location = button.location... but unless the label and the buttons are the exactly the same size in exactly the same location then the event wont trigger.

Is there an easy solution to this?
