CValue::ValueField Union Reference

## Detailed Description

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.

Example:
  Demonstrates the CValue extractor methods

              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;
