How to drag and move winform with the mouse

I know how to drag and drop winform by adding the following code

Protected Overrides Sub WndProc(ByRef m As Message)
    If (((m.Msg = 163) And ClientRectangle.Contains(PointToClient(New Point(m.LParam.ToInt32)))) And (m.WParam.ToInt32 = 2)) Then
        m.WParam = CType(1, IntPtr)
    End If
    MyBase.WndProc(m)
    If ((m.Msg = 132) And (m.Result.ToInt32 = 1)) Then
        m.Result = CType(2, IntPtr)
    End If
End Sub

But after adding the panel to winform, I can not “drag and move” the winform within this area of ​​the panel. Any idea on how to “drag and drop” inside the panel? I mean the mouse point, click, hold and move inside this panel, and winform will follow the mouse movement until I release the mouse button.

Update: solution to my problem.

'Add these to your form class
Private MouseIsDown As Boolean = False
Private MouseIsDownLoc As Point = Nothing

'This is the MouseMove event of your panel
Private Sub panel_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs) Handles Panel3.MouseMove
    If e.Button = MouseButtons.Left Then
        If MouseIsDown = False Then
            MouseIsDown = True
            MouseIsDownLoc = New Point(e.X, e.Y)
        End If

        Me.Location = New Point(Me.Location.X + e.X - MouseIsDownLoc.X, Me.Location.Y + e.Y - MouseIsDownLoc.Y)
    End If
End Sub

'And the MouseUp event of your panel
Private Sub panel_MouseUp(ByVal sender As Object, ByVal e As MouseEventArgs) Handles Panel3.MouseUp
    MouseIsDown = False
End Sub
