推荐答案

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

有关快速说明，请将ToolTip控件放在表单上。

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