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;
