"field of text box", textboxes to not have "fields" so your first question makes no sense.
"to ovoid an wrong type of data", it's called "defensive programming". It is up to you to use the appropriate controls and data validation to prevent this scenario.

VB

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    'Set up a quick description
    ToolTip1.SetToolTip(TextBox1, "Enter a positive number")
    'TO activate
    TextBox1.Enabled = True
    'To Select the control
    TextBox1.Focus()
    'TO deactivat
    TextBox1.Enabled = False

End Sub

For the quick description, place the ToolTip control onto your form.
