CValue::ValueField Union
Reference
#include <xsi_value.h>
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;
