FileSystemTask.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker) FileSystemTask.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker) Method

Definition

Initializes the properties associated with the task. This method is called by the runtime and is not used in code.

public:
 override void InitializeTask(Microsoft::SqlServer::Dts::Runtime::Connections ^ connections, Microsoft::SqlServer::Dts::Runtime::VariableDispenser ^ variableDispenser, Microsoft::SqlServer::Dts::Runtime::IDTSInfoEvents ^ events, Microsoft::SqlServer::Dts::Runtime::IDTSLogging ^ log, Microsoft::SqlServer::Dts::Runtime::EventInfos ^ eventInfos, Microsoft::SqlServer::Dts::Runtime::LogEntryInfos ^ logEntryInfos, Microsoft::SqlServer::Dts::Runtime::ObjectReferenceTracker ^ refTracker);
public override void InitializeTask (Microsoft.SqlServer.Dts.Runtime.Connections connections, Microsoft.SqlServer.Dts.Runtime.VariableDispenser variableDispenser, Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents events, Microsoft.SqlServer.Dts.Runtime.IDTSLogging log, Microsoft.SqlServer.Dts.Runtime.EventInfos eventInfos, Microsoft.SqlServer.Dts.Runtime.LogEntryInfos logEntryInfos, Microsoft.SqlServer.Dts.Runtime.ObjectReferenceTracker refTracker);
Parameters
connections
Connections Connections

A collection of connections used by the task.

variableDispenser
VariableDispenser VariableDispenser

A VariableDispenser object for locking variables.

events
IDTSInfoEvents IDTSInfoEvents

An object that implements the IDTSInfoEvents interface for raising events (errors, warnings, and so on) during persistence.

log
IDTSLogging IDTSLogging

An object that implements the IDTSLogging interface.

logEntryInfos
LogEntryInfos LogEntryInfos

TheLogEntryInfos collection used by the task.

refTracker
ObjectReferenceTracker ObjectReferenceTracker

An object reference tracker.

Examples

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"];  
}  

Remarks

For the FileSystemTask and all other stock tasks, use this method to set the log events of each task.
