IOleInPlaceSite::GetWindowContext method

Enables an in-place object to retrieve the window interfaces that form the window object hierarchy, and the position in the parent window where the object's in-place activation window should be located.

Syntax


HRESULT GetWindowContext(
  [out]      IOleInPlaceFrame **ppFrame,
  [out]      IOleInPlaceUIWindow **ppDoc,
  [out]      LPRECT lprcPosRect,
  [out]      LPRECT lprcClipRect,
  [in, out]  LPOLEINPLACEFRAMEINFO lpFrameInfo
);

Parameters

ppFrame [out]

A pointer to an IOleInPlaceFrame pointer variable that receives the interface pointer to the frame. If an error occurs, the implementation must set ppFrame to NULL.

ppDoc [out]

A pointer to an IOleInPlaceUIWindow pointer variable that receives the interface pointer to the document window. If the document window is the same as the frame window, ppDoc is set to NULL. In this case, the object can only use ppFrame or border negotiation. If an error is returned, the implementation must set ppDoc to NULL.

lprcPosRect [out]

A pointer to a RECT structure for the rectangle containing the position of the in-place object in the client coordinates of its parent window. If an error is returned, this parameter must be set to NULL.

lprcClipRect [out]

A pointer to a RECT structure for the outer rectangle containing the in-place object's position rectangle (lprcPosRect). This rectangle is relative to the client area of the object's parent window. If an error is returned, this parameter must be set to NULL.

lpFrameInfo [in, out]

A pointer to an OLEINPLACEFRAMEINFO structure the container is to fill in with appropriate data. If an error is returned, this parameter must be set to NULL.

Return value

This method returns S_OK on success. Other possible return values include the following.

Return codeDescription
E_INVALIDARG

One or more of the supplied pointers is invalid.

E_UNEXPECTED

An unexpected error has occurred.

 

Remarks

The OLEINPLACEFRAMEINFO structure provides data needed by OLE to dispatch keystroke accelerators to a container frame while an object is active in place.

When an object is activated, it calls GetWindowContext from its container. The container returns the handle to its in-place accelerator table through the OLEINPLACEFRAMEINFO structure. Before calling GetWindowContext, the object must provide the size of the OLEINPLACEFRAMEINFO structure by filling in the cb member, pointed to by lpFrameInfo.
