Const.PM_DataSourceHitCount
Applications and the framework send the Const.PM_DataSourceHitCount message to a data source to get the number of records that match a certain query condition (where-statement).
| Name | Description |
|---|---|
| nWhat = wParam | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType |
| sWhere = SalNumberToHString( lParam ) | Optional where statement. If no where statement is supplied, the current where statement is used. |
When nWhat = Const.METHOD_Inquire, TRUE is returned.
When nWhat = Const.METHOD_Execute, the return value is the number of records matching the query condition.
The Const.PM_DataSourceHitCount message is the message sent by the query dialog when the user presses the Count Hits button.
