Module 19: Validation

 

Validation

01. The validation unit for the Orders form is set to Item. This master-detail form contains an Order block and a multi record Order Items block. Why might you want to create a When-Validate-Record trigger on the Orders block in this form?                                                                                                                                         

A. To check that all required items in the Orders block have values.                                                             

B. To check that all required items in the Order Items block have values.                                                               

C. To check that the shipping data for is not earlier than the order date.                                                               

D. To perform some logic whenever a user navigates to a different record in the queried block.

Answer: C

02. You are testing a form. How can you programmatically disable validation during testing?                                                                                                                                                                                                               

A. You cannot programmatically disable validation in a form.                                                                             

B. Use the SET_FORM_PROPERTY built-in to set the VALIDATION property.                                                                   

C. Use the SET_FORM_PROPERTY built-in to set the VALIDATION_UNIT property.                                                               

D. Use the SET_FORM_PROPERTY built-in to set the DEFER_REQUIRED_ENFORCEMENT property.                                                   

E. Use the CLEAR_FORM, CLEAR_BLOCK, and EXIT_FORM built-ins with the NO_VALIDATE argument.  

Answer: B

03. Which built-in can you use to programmatically set the validation status for all records in a block?                                                                                                                                                                             

A. SET_BLOCK_PROPERTY                                                                                                                    

B. SET_RECORD_PROPERTY                                                                                                                   

C. SET_ITEM_PROPERTY                                                                                                                     

D. You cannot use a built-in; you must set a system variable instead.                                                                   

E. You cannot programmatically set the validation status because it is controlled by Forms internal processing.

Answer: E
