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()
주의
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.

예
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
