        texto.Text = txtTexto.Text
        texto.ForeColor = Color.Black
        texto.BackColor = Color.SeaShell
        texto.Location = New System.Drawing.Point(txtTexto.Location.X, txtTexto.Location.Y - 26)
        Me.Controls.Add(texto)
 
    End Sub
 
    Private Sub txtTexto_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtTexto.MouseLeave
