SaveHistory method

  • 项目

Saves the state of a component.

Syntax

HRESULT retVal = object.SaveHistory(pStream);

Parameters

  • pStream [in]
    Type: IStream

    A pointer to the stream in which the object saves its persistent state.

Remarks

The container calls IPersistHistory::SaveHistory to request that the component save its state.

The component should never add a reference to the supplied stream. The stream is not cached by the component.
