Paramètres

connections
A Connections collection for the task.

variableDispenser
A VariableDispenser object for locking variables.

events
An object that implements the IDTSInfoEvents interface for receiving events.

log
An object that implements the IDTSLogging interface for logging events.

eventInfos
A EventInfos object.

logEntryInfos
A LogEntryInfos object.

refTracker
An ObjectReferenceTracker object.

Notes

The run-time engine calls this method immediately after the task is created, and before validation, execution, or persistence operations. For the Exec80PackageTask and all other stock tasks, this method is used to set the log events of each task. The run-time engine calls InitializeTask immediately after the task is created, and before validation, execution, or persistence operations.

Exemple

Task developers define custom events by overriding the InitializeTask method of the Task base class, and creating a new EventInfo. The following code sample shows the InitializeTask method of a custom task in which two custom events are created and added to the EventInfoscollection.

public override void InitializeTask(Connections connections, VariableDispenser variables, IDTSInfoEvents events, IDTSLogging log, EventInfos eventInfos, LogEntryInfos logEntryInfos, ObjectReferenceTracker refTracker)
{
    this.eventInfos = eventInfos;
    string[] paramNames = new string[1];
    TypeCode[] paramTypes = new TypeCode[1]{TypeCode.Int32};
    string[] paramDescriptions = new string[1];

    paramNames[0] = "InitialValue";
    paramDescriptions[0] = "The value before increment.";

    this.eventInfos.Add("OnBeforeIncrement","Fires before the task increments the value.",true,paramNames,paramTypes,paramDescriptions);
    this.onBeforeIncrement = this.eventInfos["OnBeforeIncrement"];

    paramDescriptions[0] = "The value after increment.";
    this.eventInfos.Add("OnAfterIncrement","Fires after the initial value is updated.",true,paramNames, paramTypes,paramDescriptions);
    this.onAfterIncrement = this.eventInfos["OnAfterIncrement"];
}
