The Property SynchroHFSQL allows to:
  • find out the refresh mode of a browsing Table control linked to a HFSQL Client/Server data file.
  • specify the refresh mode of a browsing Table control linked to a 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:
Synchronizing the display
Example
// Defines the refresh mode of Table control
TABLE_Client.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

Finding out the refresh mode of a browsing Table control linked to a HFSQL Client/Server data file. Hide the details

<Result> = <Browsing Table control>.SynchroHFSQL
<Result>: Integer constant
Current refresh mode:
syncAdditionSynchronization when adding a record into the data file.
syncNoneNo synchronization is performed.
syncModificationSynchronization when modifying a record in the data file
syncDeletionSynchronization when deleting a record from the data file
<Browsing Table control>: Control name

<New mode>: Integer constant (or combination of constants)
New refresh mode:
syncAdditionSynchronization when adding a record into the data file.
syncNoneNo synchronization is performed.
syncModificationSynchronization 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.
syncDeletionSynchronization 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

    • the browsing tables linked to a HFSQL Classic file,
    • the browsing tables that handle files via a Native Connector (also called Native Access),
    • the memory tables, ...
  • Caution: Enabling this feature increases the server load when displaying the Table control or when moving in 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.
