SalBoolean WizardPrevious( SalNumber nWhat, SalString sStep )
The WizardPrevious hook method is called by the framework when the user selects the Previous button. Applications should override this method to add extra checks to see if the Previous operation is available, or extra statements to be executed when the user chooses Previous.
| Name | Description | SalNumber nWhat | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute. | SalString sStep | Name of the previous step - the step that will be activated after this method returns. |
|---|
When nWhat = Const.METHOD_Inquire: applications should return TRUE if the Previous operation is available, FALSE otherwise.
When nWhat = Const.METHOD_Execute: applications should return TRUE if the Previous operation was successfully performed, FALSE otherwise.
If standard behavior is desired, there is no need to override this method.
