# IOleInPlaceObject::SetObjectRects

Indicates how much of the in-place object is visible.

HRESULT SetObjectRects(

LPCRECT lprcPosRect, | //Pointer to the position of the in-place object
LPCRECT lprcClipRect | //Pointer to the outer rectangle containing the in-place object’s position rectangle
); |

Parameters

lprcPosRect
  [in] Pointer to the rectangle containing the position of the in-place object using the client coordinates of its parent window.
lprcClipRect
  [in] Pointer to the outer rectangle containing the in-place object’s position rectangle (PosRect). This rectangle is relative to the client area of the object’s parent window.

Return Values

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

S_OK
  The operation successfully indicated the rectangle.

Remarks

It is possible for lprcClipRect to change without lprcPosRect changing.

The size of an in-place object’s rectangle is always calculated in pixels. This is different from other OLE object’s visualizations, which are in HIMETRIC.

Note While executing IOleInPlaceObject::SetObjectRects, do not make calls to the Windows PeekMessage or GetMessage functions, or a dialog box. Doing so may cause the system to deadlock. There are further restrictions on which OLE interface methods and functions can be called from within SetObjectRects.

#### Notes to Callers

The container should call IOleInPlaceObject::SetObjectRects whenever the window position of the in-place object and/or the visible part of the in-place object changes.

#### Notes to Implementers

The object must size its in-place window to match the intersection of lprcPosRect and lprcClipRect. The object must also draw its contents into the object’s in-place window so that proper clipping takes place.

The object should compare its width and height with those provided by its container (conveyed through lprcPosRect). If the comparison does not result in a match, the container is applying scaling to the object. The object must then decide whether it should continue the in-place editing in the scale/zoom mode or deactivate.
