A text box is a control that is used to display text
to, or receive text from, the user. It is presented as a rectangular box
that cannot indicate what it is used for. For this reason, a text box is
usually accompanied by a label that indicates its purpose.
To create a text box, on the Toolbox, click the TextBox
button and click the form.
The TextBox control is based on the TextBox
class. This can be used to programmatically create the control. To do
this, declare a pointer to TextBox. Use the new operator to
initialize it with its default constructor.
