ANSWER: I have talked to my guiding angels, and my spiritual teachers for this problem, they all failed to provide a solution. They all suggest that unless I am provided with the source code I would have no clue about this problem :).

Answer change this:
Private Sub btn_child_form1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_child_form1.Click
Dim chld_frm2 As New Child_Form2()
chld_frm2.MdiParent = Parent_Form
chld_frm2.Show()
End Sub
End Class
To this:
Private Sub btn_child_form1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_child_form1.Click
Dim chld_frm2 As New Child_Form2()
chld_frm2.MdiParent = Me.MdiParent
chld_frm2.Show()
End Sub
End Class
