Step 8. Add Update Employee Note Logic
The Multi-Line Edit Box is a list control. Its default properties include MaximumLineLength = 4096, MaximumLines = 10,000 and WordWrap = True. Our field xEmployeeNote is a String field, length 4096. Once text has been added by an ADD_ENTRY, the user can extend and change the text. This could include adding sufficient text to exceed 4096 which would need to create a second entry in the table xEmployeeNotes. We will keep this exercise simple, but our code could easily check for a second entry and provide a warning "Not saved" or create a new record in the table xEmployeeNotes.
Always remember to use F2 to open the Features tab for any component. You can then obtain further help for a control by double clicking on a property, event or method.
1.We need to extend the SaveNoteButton.Click event to perform the following:
Assign notes CreateUpdate date field to current date/time
Selectlist xEmployeeNotes
Update fields CreateDate and Note in table xEmployeeNotes with key GUID
Leave loop /* process one entry only */
End Select
- Rebuild list NotesList
Clear NotesList
Select fields NotesList from table xEmployeeNotesByEmployee with key xEmployeeIdentification
Add entry NotesList
End Select
Your code should look like the following:
Evtroutine Handling(#SaveNoteButton.Click)
#xEmployeeNoteCreateUpdate := #xEmployeeNoteCreateUpdate.now
Selectlist Named(#EmployeeNotes)
Update Fields(#xEmployeeNote #xEmployeeNoteCreateUpdate) In_File(xEmployeeNotes) With_Key(#xEmployeeNoteGUID)
Leave
Endselect
Clr_List Named(#NotesList)
Select Fields(#NotesList) From_File(xEmployeeNotesByEmployee) With_Key(#xEmployeeIdentification)
Add_Entry To_List(#NotesList)
Endselect
Endroutine
Note: Your form is designed to handle a single employee and edit a single note. Your updates are using the current form variables for xEmployeeIdentification and xEmployeeNoteGUID.
2. Compile and test the form. Having selected a note for an employee you can now edit or extend the text in the multiline edit box, save the changes and see the employee notes list refreshed.
Note: You will find that the Multiline edit box supports Find (Ctrl+F), GoTo(Ctrl+G), Replace (Ctrl+H) and Print (Ctrl+P) dialogs.
