Méthode RegisterEvents

Syntaxe

'Déclaration
Public Overridable Sub RegisterEvents
'Utilisation
Dim instance As PipelineComponent

instance.RegisterEvents()

public virtual void RegisterEvents()

public:
virtual void RegisterEvents()

abstract RegisterEvents : unit -> unit 
override RegisterEvents : unit -> unit 

public function RegisterEvents()

Notes

This method is overridden by components that create custom events. Because the custom events declared by a component are not persisted in the package XML, this method is called as the component is loaded into the designer, and at the start of execution.

For more information, see Déclenchement et définition d'événements dans un composant de flux de données.

Exemples

The following example shows a component that overrides this method and creates a custom event using the EventInfos collection.

public override void RegisterEvents()
{
string[] parameters = new string[1]{"Parameter1"};
ushort[] types = new ushort[1]{DtsConvert.VarTypeFromTypeCode(TypeCode.String)};
string[] descriptions = new string [1]{"The first parameter."};

EventInfos.Add("OnPreExecute", "Fires when the PreExecute method runs.", false, ref parameters, ref types, ref descriptions);

}

Public Overrides Sub RegisterEvents() 
 Dim parameters As String() = New String(1) {"Parameter1"} 
 Dim types As System.UInt16() = New System.UInt16(1) {DtsConvert.VarTypeFromTypeCode(TypeCode.String)} 
 Dim descriptions As String() = New String(1) {"The first parameter."} 
 EventInfos.Add("OnPreExecute", "Fires when the PreExecute method runs.", False, parameters, types, descriptions) 
End Sub
