Creating Password Controls

You can convert a text box into a password control, where the text the user types is masked with asterisks (*). You can see this in the Textboxes example on the CD-ROM in Figure 15.8. You create a password control by setting a text box's TextMode property to Password, as I've done for the text box under the button in the Textboxes example. In HTML, this becomes an <input> element with the type attribute set to "password":

<input name="TextBox3" type="password" id="TextBox3"
style="height:24px;width:118px;Z-INDEX: 104; LEFT: 101px;
POSITION: absolute; TOP: 146px" />

In code, you can read the text in the password control using the control's Text property, as I do in the Textboxes example, where I transfer the text from the password control to the text box under it, like this:

    Private Sub Button1_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles Button1.Click
        TextBox1.Text = "You clicked the button."
        TextBox2.Text = "You clicked the button."
        TextBox4.Text = TextBox3.Text
    End Sub

You can see the result in Figure 15.8.
