This piece of code from working routine, I use KeyPress event
to drop on to next textbox, i.e.:
Private Sub txtRoof_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtRoof.KeyPress
If Char.IsNumber(e.KeyChar) = False And Microsoft.VisualBasic.AscW(e.KeyChar) <> 46 Then
If e.KeyChar = CChar(DSep) Then
e.Handled = True
ElseIf Microsoft.VisualBasic.AscW(e.KeyChar) = 13 Then
Me.txtGrunt.Select()'' next box selected, so you can add any text string here
'' something like
-------------'' Me.txtGrunt.Text=txtRoof.Text ''-------------------
e.Handled = False
Else
e.Handled = True
End If
End If
End Sub
