SendMailTask.InitializeTask 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);
override this.InitializeTask : Microsoft.SqlServer.Dts.Runtime.Connections * Microsoft.SqlServer.Dts.Runtime.VariableDispenser * Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents * Microsoft.SqlServer.Dts.Runtime.IDTSLogging * Microsoft.SqlServer.Dts.Runtime.EventInfos * Microsoft.SqlServer.Dts.Runtime.LogEntryInfos * Microsoft.SqlServer.Dts.Runtime.ObjectReferenceTracker -> unit
Public Overrides Sub InitializeTask (connections As Connections, variableDispenser As VariableDispenser, events As IDTSInfoEvents, log As IDTSLogging, eventInfos As EventInfos, logEntryInfos As LogEntryInfos, refTracker As ObjectReferenceTracker)

Parameters

connections
Connections

A collection of connections used by the task.

variableDispenser
VariableDispenser

A P:Microsoft.SqlServer.Dts.Runtime.DtsContainer.VariableDispenser object for locking variables.

events
IDTSInfoEvents

An object implementing the T:Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents interface.

log
IDTSLogging

An object implementing the T:Microsoft.SqlServer.Dts.Runtime.IDTSLogging interface.

eventInfos
EventInfos

A collection containing events to be raised during execution of the task.

logEntryInfos
LogEntryInfos

A collection of log entries.

refTracker
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, where 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 SendMailTask and all other stock tasks, this method is used to set the log events of each task.

The SSIS runtime calls InitializeTask immediately after the task is created, before validation, execution, or persistence operations.
