void OnSliderPositionChanged( 
   int Id,
   double Value
)

void OnSliderPositionChanged( 
&   int Id,
&   double Value
) 

Parameters

Id

ID of slider control

Value

Value indicating the new position of the slider

Although Value is declared as a double, the value of a slider is always a long. When this method is called, Value can be cast to a long.

If IPropertyManagerPageSlider::Style is set to swPropMgrPageSliderStyle_NotifyWhileTracking, then you can use:

• IPropertyManagerPage2Handler7::OnSliderPositionChanged to receive notifications every time the position of the slider changes because the slider is being dragged.
  
  NOTE: This might result in numerous calls to the handler, which is fine if the add-in responds quickly to each call. However, if the add-in responds slowly, then a performance bottleneck might occur.
   

• IPropertyManagerPage2Handler7::OnSliderTrackingCompleted to receive one notification when dragging of the slider is completed.
