Explanation:
C: You can use the attachable PL/SQL libraries to implement a flexible message function formessages
that are displayed programmatically by the built-in routines MESSAGE orCHANGE_ALERT_MESSAGE,
or by assigning a message to a display item from a triggeror procedure.
D: Creating Calculated Items
Change the Item Type to Display Item.
Set the Calculation Mode property to Formula.
Set the Formula property to the required formula.
Incorrect answers:
B: Display items and text items are fairly similar and share many of the same properties. The biggest
difference between the two is that a user can navigate to a text item and change its value. This is not
possible with a display item. As its name implies, it merely displays information.
Note: Display items do not allow any user interaction - they merely display data and never accept
cursor focus.
Use a display item for the following situations:
* Null-canvas fields
* Context fields
* Fields that act as titles or prompts

Question 3

An LOV must be displayed several times in your form; therefore, good performance when displaying
LOV is essential. In a When-New-Form-instance trigger, you want to save the ID of the LOV in a global
variable so that you can use it in any code to display the LOV.
Which built-in would you use to get the ID of the LOV?

  • A. SHOW_LOV

List of Values(LOV) are used either when a selected list is too long and hence would not be
appropriate for a drop down, but needs a search form to select the value.
Steps to create LOV functionality:
* Click on the LOV icon in the object navigator and choose a manual/automatic wizard. This will
create a record group.
* Open a search form in the Dialog Page
* Select values inside this form.
* Return selected values to the original page.

Question 7

Customers log in to your Orders application by using their customer ID, which is saved as a global
variable. When the Orders form first comes up, you want it to be populated with the customer's
orders, and you do not want customers to be able to query for another customer's orders.
You code the following triggers:
When-New Form instance on the Orders form:
GO_BLOCK('orders');
EXECUTE_QUERY;
You also have a button in the Control block labeled Query Orders with a When-Button Pressed trigger
that has the same code as the When New-Form instance trigger.
To test the form, you run it and log in a Customer 104. When you click Query Orders, all orders are
shown, not just those for Customer 104.
What is the best way to correct this issue to ensure that the customer can never query another
customer's orders?

  • A. Delete the Key-Exeqry trigger and add the its first line after the call to GO_BLOCK in the When- New-Form-instance trigger.
  • B. Change the last line of the When-Button-Pressed code to: DO_KEY ('EXECUTE_QUERY');
  • C. Delete the Key-Exqry trigger and put its code in an On-Select trigger.
  • D. Delete the Key-Exqry trigger and put its code in a Pre-Query trigger.

Question 8

The Orders form, whose properties have not been changed from the default, has two non-base table
text items to display the sales representative's first and last names.
You want to ensure that entries made in these Items correspond to an existing employee, so you
write a When-Validate-Item trigger for the Sales_Rep_First_Name text item:
SELECT LAST_NAME Into :last_name FROM employees
WHERE first_name = :first_name;
EXCEPTION
WHEN NO_DATA_FOUND THEN
MESSAGE ('There is no sales rep by this name');
When you test the form and enter a first name that does not exist in the database, the message that
you specified appears, but the cursor goes to the Sales_Rep_Last_Name item. You want the cursor to
remain in the Sales_Rep__First Name item until a correct first name is entered.
Also, as you continue to test the form, at times, the cursor does not leave the Sales_Rep_First_Name
item after you enter a name, but no error message appears.
Which two things can you do to correct these problems?

  • A. Add the code to handle the FORM_TRIGGER_FAILURE exception.
  • B. Raise the FORM_TRIGGER_FAILURE exception.
  • C. Add code to handle the TOO_MANY_ROWS exception.
  • D. Raise the TOO_MANY_ROWS exception.
  • E. Code an On-Error trigger.
  • F. Code an On-Message trigger.
  • G. Write a When-Validate-Item trigger for the Sales_Rep_Last_Name item.
  • H. Move the code to a form-level When-Validate-Item trigger.
  • I. Change the form's validation Unit property to Record.

Question 14

You have been assigned to maintain a Forms application that was designed by a developer who has
left the company.
The CV_Tools canvas contains several buttons. There is limited space on the canvas, but the first
button is not quite wide enough to display its complete label. In the Layout Editor, you widen the
button slightly and find that the width of all the buttons increases so that they now overlap each
other.
What could have caused this problem?

  • A. The buttons inherit their properties from the same property class.
  • B. The buttons were created by dragging them from an object group.
  • C. The buttons were created by using a Smart Class.
  • D. All other buttons were subclassed from the first button.
  • E. All other buttons were copied from the first button.
  • F. The first button was subclassed from another button.
  • G. The first button was copied from another button.

Explanation:
D (not F): With subclassing you can make an exact copy, and then alter the properties of some
objects if desired. If you change the parent class, the changes also apply to the properties of the
subclassed object that you have not altered. However, any properties that you override remain
overridden. This provides a powerful object inheritance model.
Incorrect answers:
A: A property class is a named object that contains a list of properties and their settings. You can use
property classes to increase productivity and improve network performance.
Here are some of the uses of a property class:
* It increases productivity by setting standard or frequently used values for common properties and
associates them with several form builder objects.
* It defines standard properties not just for one particular object but also for several at a time. This
results in increased productivity, because it eliminates the time spent on setting identical properties
for several objects.
* It improves network performance by increasing the efficiency of message diffing.
C: A SmartClass is a special member of an Object Library. It can be used to easily subclass existing
objects in a form using the SmartClass option from the right mouse button popup menu.
E, G: When you copy an object, a separate, unique version of that object is created in the target
module. Any objects owned by the copied object also get copied. Changes made to a copied object in
the source module do not affect the copied object in the target module.

Question 15

You have a form with a single multi-record block. During a session, a user performs an insert and
clicks Save
What is the behavior of the record being inserted violates a database constraint?

  • A. The record is posted to the database but not committed. The form redisplays the record with an error message so that the user can correct the data. Navigation to another record cannot occur until the correct data is committed or the new record is deleted. If the user exits the form without correcting the entry, a database rollback is performed.
  • B. The record is committed to the database. The form redisplays the record with an error message so that the user can correct the data. The user is unable to exit the form or move to another record until the correct data is committed of the new record is deleted.
  • C. A database rollback is performed. The form redisplays the record with an error message so that the user can correct the entry. The user is able to navigate to another record or exit the form.
  • D. A database rollback is performed. The form redisplays the record with an error message so that an correct the entry. Navigation to another record cannot occur until the correct data is committed or the record is deleted.
