SAM_CountRows is sent to a table window that has a dynamic scroll range. Use it to query an application for the number of rows in a table window. The user scrolls to the last row in a table window (by pressing a key such as the End key). Applications process the SAM_CountRows message by returning the number of rows in the table window. Typically, this involves counting the number of rows in a result set. If an application does not process the SAM_CountRows message, SAM_FetchRow messages are used to determine the last row in a table window, namely with a TBL_NoMoreRows return from the message. Processing SAM_CountRows, however, yields better performance. Message Variables hWndForm Handle of the table window. hWndItem Handle of the table window. wParam Unused. IParam Unused. Return The number of rows in the table. Example Table Window: tblEmployee Title: Employees ... Message Actions On SAM_Create Call SqlPrepare ( hSqlPri
