用法
Dim instance As IDTSComponentEvents

Dim eventText As String
Dim arguments As Object()
Dim subComponent As String
Dim fireAgain As Boolean
instance.FireCustomEvent(eventName, eventText, _
arguments, subComponent, fireAgain)

string eventName,
string eventText,
ref Object[] arguments,
string subComponent,
ref bool fireAgain
)
void FireCustomEvent(
String^ eventName,
String^ eventText,
array<Object^>^% arguments,
String^ subComponent,
bool% fireAgain
)
abstract FireCustomEvent :

subComponent:string *
fireAgain:bool byref -> unit
function FireCustomEvent(
eventName : String,
eventText : String,
arguments : Object[],
subComponent : String,
fireAgain : boolean
)
参数
- eventName
类型：System.String
The name of the event to raise.
- eventText
类型：System.String
The text describing the event.
- arguments
类型：array<System.Object[]%
An array of arguments to pass to the event.
- subComponent
类型：System.String
A String that contains more detail about the event source.
- fireAgain
类型：System.Boolean%
A Boolean that indicates this should continue firing or stop firing. A value of true indicates that it should continue firing.
注释
Because firing of an event may be expensive, the run-time engine provides a mechanism for suppressing events that you are not interested in. Every event firing method has a FireAgain parameter. If the value of this variable is false, then after the method returns, the caller will not fire this event again for the duration of the current execution.
Several of the events have a subComponent parameter that allows for even greater granularity in event source identification.
