| Result | True : Succès, False : Erreur de création de la tâche |

Exemple :
function doExecuteMyTask:string;
var inst:TTaskFormController; myCallBack:myCallBackTask; aReason:string;
begin
// Instance of the call which must be called after execution of the task
// Just need to retreive the EventID of the call back
myCallBack := myCallBackTask.Create;
inst := TTaskFormController.Create;
// Previously configured parameters
inst.TaskParameters := myProcessusParameters;
// In the case the task generate a document (for example a report)
// We want to generate a document and to attach it to the main object
// (The main object may be any persistent object)
inst.DocumentAttachOID := mainObject.InstanceOID;
// We want to generate an event to execute asynchronously a call back
inst.TaskEventID := myCallBack.EventID;
// We want to retreive the log entry for this task
inst.TaskReference := InstanceOID;
// Execute asynchronously
inst.ExecuteAsTask(aReason);
end;
