質問 1：
The Orders form has four blocks. The Orders and Order_items block are on the CV_Order content canvas; the inventories block items are on the CV_inventories content canvas; and Control block buttons are on the CV_Buttons toolbar canvas. All buttons have mouse Navigate set to No.
The Order_Items block is a detail of Orders. The inventories block is a detail of Order_Items, showing the stock of the selected product.
There is a button in the Control block with a When-Button-Pressed trigger:
IF GET_CANVAS_PROPERTY(:SYSTEM.cursor_item, item_canvas) = 'CV_ORDER'
THEN
GO_BLOCK ('inventories')
ELSE
GO_BLOCK('orders');
END IF;
When you run the form and click the button, navigation does not occur, and the form displays the runtime error "FRM-41053: Cannot find Canvas: invalid ID." What should you do to correct this problem?
A. Chang the argument to the GO_BLOCK built-ins to uppercase
B. in the first line of code, change the system variable to: SYSTEM.CURSOR_CANVAS.
C. Chang the Mouse Navigator property of the button to yes
D. in the first line of code, change the CV_ORDER to lowercase
E. in the first line of code, change the built-in to GET_ITEM_PROPERTY
F. Change the sequence of blocks in the Object Navigator

質問 3：
You are implementing a JavaBean in a form, the bean has no visible component on the form when invoked, the bean displays an input text where users enter a zip code, the bean has a single method that returns a short weather forecast for that zip code as a character value.
How can you retrieve that value so that you can display it to the user?
A. Use FBEAN.ENABLE_EVENT to register a listener for the bean event. Obtain the value of SYSTEM.CUSTOM_ITEM_EVENT in a When-Custom item Event trigger, and then use that value as an argument to the MESSAGE built in.
B. Use FBEAN.REGISTER_BEAN to register the bean, so that when the user enters a zip code into the bean s input text, the value is automatically displayed in the bean area item.
C. Use FBEAN.ENABLE_EVENT to register a listener for the bean event. Obtain the value of SYSTEM.CUSTOM_EVENT_PARAMETER in a When_Custom-item-Event trigger, and then use that value as an argument to the MESSAGE built-in.
D. Use FBEAN.REGISTER_BEAN as an argument to the MESSAGE built in to invoke the bean's method and return the value as a message displayed to the user.

質問 4：
In the Orders form, users often have a need to return to the first record. Because there are many employee records, it may take a long time for them to scroll up to the first record, so you create a button with the label First Record.
When users click the first Record button, you want to display your own custom message instead of the system message "FRM-40100: At first record." The system message should be displayed in other cases when users attempt to scroll above the first record.
You code the following When-Button-Pressed trigger:
:SYSTEM.mesage_level := '5'
UP;
WHILE FORM_SUCCESS LOOP
UP;
END LOOP;
MESSAGE ('This is the first Order');
The button works perfectly to return to the first record and display your custom message instead of the system message. However, users report that as they continue to use the form after clicking the button, no longer see other helpful messages. For example, the message "FRM 40102: Record must be entered or deleted first" no longer appears when they attempt to scroll past the last record.
How can you resolve this Issue so that all system messages continue to be displayed after the trigger code runs?
A. instead of setting the system message level to 5 in the code, set it to 25.
B. Instead of setting the system message level in the When-Button-Pressed trigger, use an On-Error trigger to customize the message.
C. Set the system message level in a When-New-Form-Instance trigger, so that all system messages appear except when in the scope of the trigger.
D. Add a line of code just after the end of the loop to reset the system message level.
E. instead of setting the system message level to 5 in the code, set it to 50.
F. Add the line of code just before the end of the loop to reset the system message level.
