# IOleInPlaceSite::Scroll

Tells the container to scroll the view of the object by a specified number of pixels.

HRESULT Scroll(

SIZE scrollExtent | //Number of pixels
); |

Parameter

scrollExtent
  [in] Number of pixels by which to scroll in the X and Y directions.

Return Values

This method supports the standard return values E_INVALIDARG and E_UNEXPECTED, as well as the following:

S_OK
  The method successfully executed the view scroll instruction.

Remarks

As a result of scrolling, the object’s visible rectangle can change. If that happens, the container should give the new ClipRect to the object by calling IOleInPlaceObject::SetObjectRects. The intersection of the ClipRect and PosRect rectangles gives the new visible rectangle. See IOleInPlaceSite::GetWindowContext for a discussion of ClipRect and PosRect.

#### Notes to Callers

Called by an active, in-place object when it is asking the container to scroll.
