Moving form with no border

[Frank McCown]

I've got a form that has no border
(FormBorderStyle.None), and I'd like to move it with the
mouse. My solution is below. Is there a better one?

Private Sub Form1_MouseDown(ByVal sender As Object, ByVal
e As System.Windows.Forms.MouseEventArgs) Handles
MyBase.MouseDown
MouseDownLoc.X = e.X
MouseDownLoc.Y = e.Y
End Sub

Private Sub Form1_MouseMove(ByVal sender As Object, ByVal
e As System.Windows.Forms.MouseEventArgs) Handles
MyBase.MouseMove
If e.Button = MouseButtons.Left Then
Me.Left += e.X - MouseDownLoc.X
Me.Top += e.Y - MouseDownLoc.Y
End If
End Sub

It appears that another method is to use the ReleaseCapture and
SendMessage API functions. I'm wondering if that isn't creating
additional overhead (although very little) since it requires sending
additional messages. Wouldn't my method be more efficient?

Mhm... You try to reimplement something that is already implemented in
Windows...
