SalNumber DataSourceIsDirty( SalNumber nWhat )
Applications and the framework call the DataSourceIsDirty method to check if any changes have been to a data source, or to ask the user to save the changes.
| Name | Description |
|---|---|
| SalNumber nWhat | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType. |
When nWhat = Const.METHOD_Inquire: the return value is TRUE if any changes have been made in the data source.
When nWhat = Const.METHOD_Execute: the return value is TRUE if the changes where saved successfully, or the user choose not to save the changes. Otherwise the return value is FALSE.
When nWhat = Const.METHOD_GetType, the return value is Const.CHILDTYPE_SourceMethod.
DataSourceIsDirty is called automatically by the framework when a data source receives the Const.PM_DataSourceIsDirty message.
