Step 3 Create the Command Handler Logic

Step 3. Create the Command Handler Logic

VFW054 – Edit Text in a Memo / Edit Box

The Brief Notes command handler is an instance list command. These means it should begin by retrieving the instance list current entry, so that it can restore notes for this employee.

1.  Create an uExecute method routine with an Options(*redefine) parameter. This routine needs to do the following:

a.  Invoke the ancestor uExecute method

b.  Invoke the List Manager GetCurrentItem method to retrieve AKey1 (contains EMPNO)

c.  Clear the Memo box

d.  Select all iiiEmpNotes records for this EMPNO and iiiNteType = G

e.  Add entries to Memo box

     Your code should look like the following:

Mthroutine Name(uExecute) Options(*redefine)
#com_ancestor.uExecute
#avlistmanager.getCurrentInstance Akey1(#empno)
Clr_List Named(#MEMO_1)
#iiiNTETYP := G
Select Fields(#MEMO_1) From_File(iiiEmpNotes) With_Key(#empno #iiiNteType)
Add_Entry To_List(#MEMO_1)
Endselect
Endroutine

2.  In this step you will add logic to handle the Save button click event.

     The Memo box has a Modified property, which your save logic can test to determine whether the notes data needs to be saved. Modify your uExecute routine so that the memo box Modified property is set to false, before clearing the Memo box. For example:

#MEMO_1.modified := false

     Remember you can find out more about any component's properties, event and methods by using the F2 Feature Help.

     Create a Click event handling routine for the Save push button. Add logic to perform the following:

If the Memo box Modified property is true – perform

Change iiiNTETYPE to G

Delete all records from iiiEmpNotes for this employee and Note Type.

Read all items in the Memo box using SELECTLIST

Insert new records to iiiEmpNotes

     Your code should look like the following:

Evtroutine Handling(#PHBN_SAVE.Click)
If (#MEMO_1.modified)
#iiiNteType := G
Delete From_File(iiiEmpNotes) With_Key(#empno #iiiNteType)
Selectlist Named(#MEMO_1)
Insert Fields(#iiiNTELNE #iiiNteType #iiiNTESQN #iiiLneCnt #empno) To_File(iiiEMPNOTE)
Endselect
Endif
Endroutine

3.  Create a Click event handling routine for the Delete button. Add logic to delete all entries for this employee with iiiNTETYPE = G.

     Clear the memo box.

     Your code should look like the following:

Evtroutine Handling(#PHBN_DLT.Click)
#iiiNteType := G
Delete From_File(iiiEmpNotes) With_Key(#empno #iiiNteType)
Clr_List Named(#MEMO_1)
Endroutine

4.  Compile your component.

5.  Execute the Framework as Designer and open the properties dialog for the Employees business object.

6.  Select the Commands Enabled tab, select the Brief Notes action and define its Windows command handler as iiiVFW08.

7.  Save and Restart the Framework as an end user.

8.  Test the Brief Notes command handler.

9.  Using standard Windows shortcuts (Copy = Ctrl+C, Paste = Ctrl+V), copy text from a portion of the LANSA Online Guides and paste it into employee brief notes.
