Exercise – Day 2

Event Rule Exercise:

Learning Objectives:

Create conditional If/Then/Else statements Create assignments Create Event Rule Logic to hid and show controls based on

condition Use Event Rules to perform calculation Use System Functions Place Check Boxes and assign DD Item to those Check Boxes. Put

logic behind those Check Boxes

Steps to complete the exercise1. Display Monthly and annual salary controls only if the

address book record is for an employee. 2. On an Add, the Employee tab on the form should initially

appear like this:

3. If the user enters Search Type of E, the form should display the Monthly Salary and Annual Salary controls:

4. If a Monthly salary is entered, the annual salary should be calculated automatically:

Hint: This logic needs to occur on multiple events

5. On work with Address Book Form, put logic on an appropriate event, which will put a ‘Yellow’ color on all the lines on Grid that have a search type ‘E’ on it.

Hint: Choose appropriate SYSTEM FUNCTION from available functions in the Grid System Functions Option

CHECK BOX EXERCISE

6. Put two CHECK BOXES on Work With Addresses form as shown on the above picture.

7. Attach both check boxes to DD Item (EV01)8. Give appropriate descriptions to the Check Boxes. Such as

Display City and Display Region9. Put logic so that when ‘Display City’ check box is CHECKED,

the column CITY displays on the Grid. Otherwise it should be hidden10. Similarly when ‘Display Region’ Check Box is CHECKED, the

columns REGION displays on the Grid. Otherwise it should be hidden

Hint: Choose System Function “HIDE/SHOW GRID COLUMNS” to hide or show the Grid Columns

RADIO BUTTON EXERCISE

1. Insert two Radio Buttons on W5501001B (Address Book Revisions) form

2. Associate both the Radio Buttons with database item ACTIVEYN3. Change the title and value for each radio button

a. Active = Yb. Inactive = N

4. Create a Group Box around the radio buttons5. Save and Exit 6. Run the application to test

NOTE: Refer to the screenshot on next page

1. Create a new Headerless Detail form in P5501001 application (Phone Numbers Revisions)

2. Attach Business View V5501023. Add Address Number as a Form control

a. Address Number should have a FILTER option of ‘=’b. Disable this control

4. Create a group box around Address Number5. Add the following grid columns and give appropriate descriptions to

columnsa. AR1 (Area Code)b. PH1 (Phone Number)c. PHTP (Phone Type)d. LNID (Line Number)

6. Set grid properties to “AUTOMATICALLY FIND ON ENTRY”7. Add “DELETE” button on toolbar8. Set form properties to “END FORM ON ADD”9. Set logical tab sequence10.Test the form11.Save the form

Form Interconnect

1. Go to P5501001 and choose work with Address Book form2. Go to Menu/Tool bar3. Add a Row Exit from Class Options4. Add a User Defined from Class Options and name it “Phones”5. Go to Event Rules Window6. Connect P5501001/W5501001A form to P5501001/W5501001E form7. Pass Address Number value into the data structure (Think which

address number value should be passed in. Is it going to be FC or GC?)

8. Save and close9. Go back to W5501001E form and assign the FC Address Number to FI

Address Number. Choose an appropriate event to do this.10.Save and close11.Test your application. Try to add records in your application. Come

back and see if those records exist.

Using Event Rule Variables for Automatic Line Numbering

Business Purpose:In the address book application, the phones screen requires line

numbers. Up to this point, when we added phone number, we entered the associated line numbers manually. This time, we will add logic so that Line ID field will automatically fetch next nember.

Steps to Complete

1. Focus on W5501001E (Phone Numbers) application2. Create a variable LNID (Scope of the variable should be Form)3. In the Name box, change the User Name to

LineNumberCounter_LNID4. Initialize variable on the appropriate event5. To initialize variable, create following assignment

a. VA frm_LineNumberCounterLNID = 06. Next, as each line is retrieved from the database, check to see if the

Line Number of that record is greater than the value of the variable. If it is greater, assign the value of the Line Number to the variable. This ensures that the variable will always be equal to the highest line number in the table before it is incremented by 1 for the final line in the grid. Use appropriate event. Hint of the code at the end of the Document.

7. Finally, increment the variable by 1 and assign the new value to the next available line. Use the appropriate event. Hint of the code at the end of the Document.

8. Disable the Line Number control in the grid.9. Save and Exit the application. Test the application

Create a Message Box Form

1. Go into the design of P5501001 and insert a new Message form from form type and call it “Confirm Delete”

2. Type the following statement on the Event Rules Title“You are about to delete phone numbers. Are you sure?”

3. Attach ‘Yes’ and ‘No’ push buttons to the form4. Go to W5501001E (Phone Numbers Inquiry) form and on the ‘Delete’

Button, call this Message box form. 5. Save and close the application6. Test the application

f Search & Select Form

Learning Objectives

Create a Search and Select form Understand why Search and Select forms usually have their own

business views Attach the Search and Select form to a data dictionary item Test the form

1. Create a new Business View V550103 (Class Address Book – Search & Select)

2. Attach F5501010 to this Business View

3. Show following columnsa. AN8b. AT1c. ALPH

4. Create a new application P550100S (Class Address Book Search & Select)

5. Choose search and select form from form types after you go into the design

6. Attach Business View V5501037. Add Alpha Name and Search Type as Form Controls

a. Alpha Name should have ‘>=’ filter and Wildcard should be set to ‘Yes’

b. Search Type should have Filter option of = and Set Wildcard to ‘Yes’

c. Align search type and alpha named. Add associated description to Search Typee. Create group box around alpha name and search type

8. Add the following grid columnsa. Address Numberb. Alpha Namec. Search Type

9. Sort grid by Address Number10. Set appropriate tab sequence11. Set the form as ENTRY POINT in form properties12. Save and Exit13. Run the application from Fast Path

Note: This application must be checked in so that the Search and Select form is available for the Data Dictionary Item that it needs to get attached to. As this can’t be done on demo, we may not be able to test it successfully. But this should give you an idea of how to create a search and select form.

HINTS

HINT STEP 6: Use the form event GRID RECORD IS FETCHED Put following logic

If BC Line Number is greater that VA frm_LineCounterNumber_LNID

VA frm_LineCounterNumber_LNID = BC Line NumberEnd If

HINT STEP 7 Use the grid event Add Last Entry Row to Grid Use the following logic

Va frm_LineCounterNumber_LNID = [VA frm_LineCounterNumber_LNID]+1

GC LineNumber=VA frm_LineCounterNumber_LNID
