Comentários
For the ExecuteSQLTask and all other stock tasks, this method is used to set the log events of each task.
The run-time engine calls this method immediately after the task is created and before it performs validation, execution, or persistence operations.
Exemplos
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 EventInfos collection.
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"];
}
