SetUIHandler method

Sets the IDocHostUIHandler interface for MSHTML.

Syntax

HRESULT retVal = object.SetUIHandler(pUIHandler);

Parameters

• pUIHandler [in]
  Type: IDocHostUIHandler

  A pointer to the host's IDocHostUIHandler interface.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

MSHTML releases its previous IDocHostUIHandler interface (if one is present) and calls the pUIHandler AddRef method.

Note   When you call ICustomDoc::SetUIHandler, MSHTML also uses your implementation of the IOleCommandTarget interface to handle commands, such as Save As. If you do not handle the call to Exec, MSHTML uses its own handler.
