t3bis.Exécute() Syntax
Running a parallel task identified by its description (Description of ParallelTask variable) Hide the details
<Result> = ParallelTaskExecute(<Task description>)
<Result>: ParallelTask variable ParallelTask variable corresponding to the task run. <Task description>: Description of ParallelTask variable Name of the Description of ParallelTask variable that describes the task to be executed. Remarks - The task is saved in the queue of tasks to run.
- <Description of ParallelTask>.Execute is not a blocking function and does not wait for task to be completed.
- Comparison between the different types of copy for the HFSQL context:
| | | | Type of copy | Benefits | Drawbacks |
|---|
| Full copy | Copies: - the extensive connection parameters (connections, physical paths, ...).
- the positions, the filters, ... defined on the data files.
- the queries.
| Memory consumption (on the client and on the server). | | Light copy | Copies the extensive connection parameters (connections, physical paths, ...). No memory consumption on the server. | The records and the current filters are not copied. Therefore, the records must be repositioned by HReadSeek for example. No copy of queries. Memory consumption on the Client computer | | Delayed copy | No memory consumption (on the client and on the server). | Risk: If the extended connection parameters are modified, the last modification will be taken into account. The records and the current filters are not copied. Therefore, the records must be repositioned by HReadSeek for example. No copy of queries. |
In most cases, the delayed copy is recommended provided that you don't change the connection parameters and that you perform the necessary calls to HReadSeek.

Unit examples (WINDEV): Using parallel tasks
[ + ] The parallel tasks are used to speed up the process times and to improve the reactivity of an application. This example presents the functions and types of variables required to use the parallel tasks: - running parallel tasks, - interaction with the controls, - continuation tasks.
