Compatibility with version 12: For backward compatibility with version 12, you also have the ability to define a task via the HScheduledTask structure. This task will run the specified stored procedure (or will perform a database backup).
Example
MyTask is hScheduledTask
MyTask.Description = "Scheduled backup " + CR + ...
DateToString(DateSys(), maskSystemDate) + " at "+ TimeToString(TimeSys(), "HH:MM:SS")
MyTask.Month = "*"
MyTask.DayOfWeek = "*"
MyTask.DayOfMonth = "*"
MyTask.Hour = EDT_Time.Hour
MyTask.Minute = EDT_Time.Minute
MyTask.NumberExecution = 1
MyTask.Procédure = "HBackup"
Add(MyTask.Parameter, gsNameCSDatabase + "/LOG_TASKSFIC")
Add(MyTask.Parameter, gsNameCSDatabase + ".ScheduledBackup")
Add(MyTask.Parameter, True)
Add(MyTask.Parameter, MyTask.Description)
nID is int = HAddTask(gsCSConnection, MyTask)

<Stored procedure>: WLanguage procedure

To add a task, you must have:
  • the corresponding rights (hRightsManageTask constant) on the server,
  • the rights to connect (hRightsConnection or hRightsEncryptedConnection) to each relevant database,
  • the rights to run the command linked to the scheduled task.
The task will be run with the account of user who created the task.
