This union is used for storing the value described by the CValue::m_t data member. Instead of accessing the value stored in CValue::m_u directly, it is strongly recommended to use the extractor methods defined by CValue.
CValue val((short)255); // good but not recommended short wrong = val.sval; // right way to do it short good = (short)val; CComAPIHandler uitoolkit; uitoolkit.CreateInstance( L"XSI.UIToolkit"); CValue dispVal = uitoolkit.GetRef(); // wrong way of accessing a COM object from a CValue, could return // an invalid pointer IDispatch* pDisp = dispVal.pval; // this is the right way to do it IDispatch* pDisp = (IDispatch*)(CValue::siPtrType)dispVal;
