Showing the form below the textbox
===

Hello I'm working on something for my thesis using Visual Basic 2005 I want the for to show below the textbox but I can get the exactly location of the textbox using Drawing Points.

Here's my code right now:

    Dim x As Integer = Me.txtStockQUnit.Location.X + Me.Location.X + Me.grpMonitoring.Location.X
    Dim y As Integer = Me.txtStockQUnit.Height + Me.txtStockQUnit.Location.Y + Me.Location.Y + Me.grpMonitoring.Location.Y
    My.Forms.frmQuantityUnitDropListGrid.Location = New Point(x, y)
    My.Forms.frmQuantityUnitDropListGrid.ShowDialog()
