During testing, you received comments that the default functionality of the [Commit] key can cause an error message to be displayed if there are no changes to save when it was activated.
You decide to provide a button for users to validate the form and issue a commit if necessary. To implement this, you write a form-level procedure called
VALIDATE_AND_COMMIT.
The same functionality must be provided when the user chooses File > Save from the menu or presses the [Commit] key.
Which should you use?

A. The When-Button-Pressed trigger with the code
DO_KEY('COMMIT_FORM');
A form-level Key-Commit trigger with the code
DO_KEY('COMMIT_FORM');
validate_and_commit;

B. The When-Button-Pressed trigger with the code
DO_KEY('COMMIT_FORM');
A form-level Key-Commit trigger with the code
validate_and_commit;

C. The When-Button-Pressed trigger with the code
DO_KEY(commit;);
A form-level Key-Commit trigger with the code
validate_and_commit;

D. The When-Button-Pressed trigger with the code
DO_KEY('[COMMIT]');
A form-level Key-Commit trigger with the code
DO_KEY('validate_and_commit');

E. The When-Button-Pressed trigger with the code
validate_and_commit;
A form-level Key-Commit trigger with the code
DO_KEY('COMMIT_FORM');

문제8
An application is accessed through the Summit form, which can open the Customers form and the Orders form. The Customers form can also open the Orders form, and the Orders form can open the Customers form. What should you do to ensure that forms are closed in the proper order so that the session closes down when the last form is exited?

A. You should make sure that the Summit form that started the session is the last one closed by coding its Key-Exit trigger to exit only if no other forms are open.

B. You should keep track of the order of the opening of forms in a global record group.
Then in the Key-Exit trigger for each form, you should
allow only the last form that was opened to be closed.

C. You do not need to do anything because Forms keeps track of the forms that are opened internally and does not allow the user to close them in the wrong order.

D. You do not need to do anything. No matter which form is closed last, the session will close properly.

정답: D

문제9
In the Orders form you define five LOVs, and you create one button to be used to display any of the LOVs.
The button is enabled only when the user navigates to a field with an attached LOV. If the user supplies only part of the required input data, the LOVs use that input as search criteria to automatically reduce the LOV contents. If the LOVs hold only one value that can possibly match user-supplied input, then the LOVs auto-complete the input field and are not displayed. Which built-in and properties should you use to display the LOVs?

A. Use the List_Values(RESTRICT) built-in, and set the Mouse Navigate property value to NO.

B. Use the List_Values(NO_RESTRICT) built-in, and set the Mouse Navigate property value to NO.

C. Use the Show_LOV built-in, and set the Mouse Navigate property value to NO.

D. Use the List_Values(RESTRICT) built-in, and set the Mouse Navigate property value to YES.

E. Use the Show_LOV built-in, and set the Mouse Navigate property value to YES.

F. Use the List_Values(NO_RESTRICT) built-in, and set the Mouse Navigate property value to YES.

문제10
You are running a form in debug mode and you begin to step through the code of a lengthy subprogram. After stepping through a few lines of its code, you realize that the error comes not from the code in that particular subprogram but from code that is executed after it. At this point, how can you immediately jump to the next line of code after the call to the subprogram?

A. Click Step Over to step over the execution of the subprogram.

B. Click Step Out to resume stepping through code after the subprogram is called.

C. You cannot do this in the same debug session. Click Stop, set a breakpoint immediately after the subprogram code is called, and run the form in debug mode again.

D. Open the Stack panel, select the previous stack frame, and click Go.
