语法

声明
Public Overridable Sub OnVariableValueChanged ( _
    DtsContainer As DtsContainer, _
    variable As Variable, _
    ByRef fireAgain As Boolean _
)

public virtual void OnVariableValueChanged (
    DtsContainer DtsContainer,
    Variable variable,
    ref bool fireAgain
)

public:
virtual void OnVariableValueChanged (
    DtsContainer^ DtsContainer, 
    Variable^ variable, 
    bool% fireAgain
)

public void OnVariableValueChanged (
    DtsContainer DtsContainer, 
    Variable variable, 
    /** @ref */ boolean fireAgain
)

JScript 不支持由引用传递值类型参数。

参数

  • DtsContainer
    The task.
  • variable
    The variable that has changed.
  • fireAgain
    A Boolean that indicates whether this should continue firing or stop firing. A value of true indicates that it should continue firing.

备注

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.
