'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

  • 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.
