Const.PM_DataSourceUserOrderBy
Applications and the framework send Const.PM_DataSourceUserOrderBy to a data source to set the order by statement to be used for the next populate.
| Name | Description |
|---|---|
| nWhatt = wParam | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType |
| sOrderBy = SalString.FromHandle(nlParam) | Order by statement to use for the next populate of the data source. |
When nWhat = Const.METHOD_Inquire, the return value is TRUE if the sOrderBy is equal to the current order by statement for the data source, FALSE otherwise.
When nWhat = Const.METHOD_Execute, the return value is TRUE.
Const.PM_DataSourceUserOrderBy is used internally in the framework by e.g. the query dialog.
