命名空間： Microsoft.SqlServer.Dts.Runtime
組件： Microsoft.SqlServer.ManagedDTS (在 Microsoft.SqlServer.ManagedDTS.dll 中)
語法
'宣告
Public Overridable Sub OnVariableValueChanged ( _
DtsContainer As DtsContainer, _
variable As Variable, _
ByRef fireAgain As Boolean _
)
'用途
Dim instance As DefaultEvents
Dim DtsContainer As DtsContainer
Dim variable As Variable
Dim fireAgain As Boolean
instance.OnVariableValueChanged(DtsContainer, _
variable, fireAgain)
public virtual void OnVariableValueChanged(
DtsContainer DtsContainer,
Variable variable,
ref bool fireAgain
)
public:
virtual void OnVariableValueChanged(
DtsContainer^ DtsContainer,
Variable^ variable,
bool% fireAgain
)
abstract OnVariableValueChanged :
DtsContainer:DtsContainer *
variable:Variable *
fireAgain:bool byref -> unit
override OnVariableValueChanged :
DtsContainer:DtsContainer *
variable:Variable *
fireAgain:bool byref -> unit
public function OnVariableValueChanged(
DtsContainer : DtsContainer,
variable : Variable,
fireAgain : boolean
)
參數
- DtsContainer
型別：Microsoft.SqlServer.Dts.Runtime.DtsContainer
The task.
- variable
型別：Microsoft.SqlServer.Dts.Runtime.Variable
The variable that has changed.
- fireAgain
型別：System.Boolean%
A Boolean that indicates whether this should continue firing or stop firing. A value of true indicates that it should continue firing.
實作
IDTSEvents.OnVariableValueChanged(DtsContainer, Variable, Boolean%)
備註
This event is called by variables whenever their value is changed. OnVariableValueChanged should not be called by tasks, because it is raised by the run-time engine by the variables. If a task calls OnVariableValueChanged, the method will return success but no event handler will be executed.
