Notifies the container that the object is about to be activated in place and that the object is going to replace the container's main menu with an in-place composite menu.
Syntax
HRESULT IOleInPlaceSite::OnUIActivate(); |
Return Value
This method supports the following return values:
| Value | Description |
|---|---|
|
S_OK |
The container allows the in-place activation. |
|
E_UNEXPECTED |
The call to the method unexpectedly failed. |
Notes to Callers
The in-place object calls IOleInPlaceSite::OnUIActivatejust before activating its user interface.
Notes to Implementers
The container should remove any user interface associated with its own activation. If the container is itself an embedded object, it should remove its document-level user interface.
If there is already an object active in place in the same document, the container should call IOleInPlaceObject::UIDeactivatebefore calling OnUIDeactivate.
