Const.PM_DataRecordRefresh
The Const.PM_DataRecordRefresh message is sent to a data source to refresh an object.
| Name | Description |
|---|---|
| nWhat = wParam | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType |
| lParam | Unused |
When nWhat = Const.METHOD_Inquire: the return value is TRUE if the refresh operation is available, FALSE otherwise.
When nWhat = Const.METHOD_Execute: the return value is TRUE if the record was successfully refreshed, FALSE otherwise.
When nWhat = Const.METHOD_GetType, the return value is Const.CHILDTYPE_SourceMethod.
DataRecordRefresh will restore the selected record to query state. E.g. The whole record will be repopulated and row flags reset.
This functionality is only implemented on table objects as cTableWindow and cChildTable.
The refresh is done without confirming dirty rowstate.
