CComControlBase::FireViewChange
Call this method to tell the container to redraw the control, or notify the registered advise sinks that the control's view has changed.
HRESULT FireViewChange( );
Return Value
One of the standard HRESULT values.
Remarks
If the control is active (the control class data member CComControlBase::m_bInPlaceActive is TRUE), notifies the container that you want to redraw the entire control. If the control is inactive, notifies the control's registered advise sinks (through the control class data member CComControlBase::m_spAdviseSink) that the control's view has changed.
Example
STDMETHODIMP CMyControl::put_Shape(int newVal)
{
// store newVal in m_nShape user-defined member
m_nShape = newVal;
// notify container to redraw control
FireViewChange();
return S_OK;
}
