[out] HWND *phwnd
);

Return value
This method returns S_OK on success. Other possible return values include the following.
| Return code | Description |

Remarks
Five types of windows comprise the windows hierarchy. When a object is active in place, it has access to some or all of these windows.
| Window | Description |
|---|---|
| Frame | The outermost main window where the container application's main menu resides. |
| Document | The window that displays the compound document containing the embedded object to the user. |
| Pane | The subwindow of the document window that contains the object's view. Applicable only for applications with split-pane windows. |
| Parent | The container window that contains that object's view. The object application installs its window as a child of this window. |
| In-place | The window containing the active in-place object. The object application creates this window and installs it as a child of its hatch window, which is a child of the container's parent window. |
Each type of window has a different role in the in-place activation architecture. However, it is not necessary to employ a separate physical window for each type. Many container applications use the same window for their frame, document, pane, and parent windows.
