Private Const HTCAPTION = 2
Private Const WM_NCLBUTTONDOWN = &HA1

Private Sub Text1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim ncl As Long
Dim rel As Long
If Button = 1 Then
Dim i As Integer

i = ReleaseCapture()
ncl = SendMessage(Text1.hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0)
End If

End Sub
