int UpdateUI (
	[InAttribute] uint dwCompRole,
	[InAttribute] int fImmediateUpdate,
	[InAttribute] uint dwReserved
int UpdateUI (
	/** @attribute InAttribute() */ UInt32 dwCompRole, 
	/** @attribute InAttribute() */ int fImmediateUpdate, 
	/** @attribute InAttribute() */ UInt32 dwReserved
function UpdateUI (
	dwCompRole : uint, 
	fImmediateUpdate : int, 
	dwReserved : uint
) : int



[in] Role of the affected in-place object. For a list of valid dwCompRole values, see OLEROLE.


[in] Flag indicating whether or not an immediate synchronous update should occur. If set to true, the update is synchronous. If set to false, the update occurs at idle time.


[in] Reserved for future use. Must be set to 0.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

COM Signature

From oleipc.idl:

HRESULT IOleInPlaceComponentUIManager::UpdateUI(
   [in] DWORD dwCompRole,
   [in] BOOL fImmediateUpdate,
   [in] DWORD dwReserved

UpdateUI can be called by either the innermost UI active object or by objects that serve as containers to this innermost object. Typically, the update of the user interface occurs at idle time rather than immediately. However, if the fImmediateUpdate parameter is set to true, the update is performed immediately (synchronously).
