<BR>

<P><FONT COLOR="#FF8000"><B><I>Concept: </I></B></FONT>Text box controls display default values and accept user input. Text box controls enable you to determine how the user enters 
data and responds to questions and controls that you display.

<BR>

<P>When you display a text box on a form, you give the user a chance to accept a default value&#151;the text box's initial Text property&#151;or to change it to something else. The user 
can enter text of any data type&#151;numbers, letters, and special 
characters. He can scroll left and right by using the arrow keys, and he can use the Ins and Del keys to insert and delete text within the text box control.

<BR>

<P>Most of the text 
box's properties work like the label control's properties. Unlike the label, however, the text box properties describe data-entry properties so that the control can deal with user input instead of simple text display. Table 5.3 
describes the property 
values for the text box control.
