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