Editing a SmartDataObject Master

Any modular system must have and enforce strict data-exchange requirements if it is to avoid possible data corruption. Although you can always update your SmartDataObject masters to reflect your changing needs, you must also update any other master objects that share data with them. Furthermore, you must sometimes update all the masters in a specific order if you are to avoid breaking the signatures on which data communication depends. For more information about making data-stream changes successfully, see the "Making Changes to the Data Stream" section in this chapter.

When you are ready to edit a SmartDataObject master, follow these steps:

  1. Choose File Open and select the main source file (for example dExampleSDO.w, not the dExampleSDO_cl.w client-only file). The SmartDataObject appears:
  2. Double-click on the object. The SmartDataObject property sheet dialog box appears:
  3. Choose the Query button to edit the existing query, if necessary. See the "Defining and Editing Queries Using Query Builder" section in this chapter for information about how to use Query Builder.
  4. Click on the Fields button to modify the original fields and their attributes. See the "Selecting Database Fields for Browsing" section in this chapter for information about how to use the Column Editor.
  5. Save your changes.
