70-306 Developing and Implementing Windows-based Applications with Microsoft Visual Basic .NET Training Boot Camp

Demo Question 8.

You are creating a data entry form that will be used by your CKParcelEx to search for parcel information. The form contains text boxes to accept each customer's name, package tracking number, customer's telephone number, customer's address and priority type. Your application will query a Microsoft SQL Server database at the time that the package tracking number is entered. If a record is found in the database with a matching tracking number, then the form will automatically enter the customer's name, customer's telephone number and customer's address; in this case, you do not want the user to be able to tab to these text boxes. However, the user should be able to select the text boxes and edit the data if necessary. Which of the following actions will prevent the user from tabbing to these text boxes while allowing the data to be edited? (Select the best choice.)

A. setting the TabIndex property of each text box to 0
B. setting the TabStop property of each text box to False
C. setting the AcceptsTab property of each text box to False
D. setting the Enabled property of each text box to False


Display Answer

Answer: B The TabStop property of a control can be set to False to prevent the control from receiving focus when the TAB key is used. The control can still receive focus when a user clicks the control. Setting the Enabled property to False prevents a control from receiving focus, but it also prevents the data inside of the control from being edited. Setting the TabIndex property of a control to 0 sets that control to receive focus first. Setting the AcceptsTab property to False causes focus to move to the next control rather than inserting a tab character when the TAB key is pressed in a multiline text box.
