SynchroHFSQL (Property) In french: SynchroHFSQL
The SynchroHFSQL property is used to: - get the refresh mode of a Table control based on a data file linked to an HFSQL Client/Server data file.
- specify the refresh mode of a Table control based on a data file linked to an HFSQL Client/Server data file.
Remark: This property is equivalent to the option "Synchronize the display" found in the "Content" tab of the description window of Table control: // Defines the refresh mode of Table control TABLE_Customer.SynchroHFSQL = syncModification // Modify the HFSQL Client/Server file linked to the control CUSTOMER.ZC = 34980 HModify(CUSTOMER) // The Table control will be automatically refreshed if this customer is visible in the control
Syntax
Getting the refresh mode of a Table control based on a data file linked to an HFSQL Client/Server data file Hide the details
<Result> = <Table control based on a data file>.SynchroHFSQL
<Result>: Integer constant Current refresh mode: | | syncAddition | Synchronization when adding a record into the data file. | syncNone | No synchronization is performed. | syncModification | Synchronization when modifying a record in the data file | syncDeletion | Synchronization when deleting a record from the data file |
<Table control based on a data file>: Control name Name of the Table control based on a data file to be used.
Changing the refresh mode of a Table control linked to an HFSQL Client/Server data file Hide the details
<Table control based on a data file>.SynchroHFSQL = <New mode>
<Table control based on a data file>: Control name Name of the Table control based on a data file to be used. <New mode>: Integer constant (or combination of constants) New refresh mode: | | syncAddition | Synchronization when adding a record into the data file. | syncNone | No synchronization is performed. | syncModification | Synchronization when modifying a record in the data file Caution: Only the rows displayed by the Table control (which means the visible rows) can be automatically modified when modifying the linked HFSQL file. | syncDeletion | Synchronization when deleting a record from the data file |
Remark: The syncAddition, syncModification and syncDeletion constants can be combined. Caution: Increasing the number of supported cases increases the server load. Remarks - This property is ignored for:
- Table controls linked to an HFSQL Classic data file,
- Table controls that handle data files via a Native Connector (also called Native Access),
- Table controls populated programmatically, etc.
- Caution: Enabling this feature increases the server load when displaying the Table control or when elements are moved within the control.
- The modifications performed in the data file can come from the same application, from another application on the same computer or from another application on another computer.
