I need an example of how to use the WriteMultipleItemValues using C++. A prior thread showed how to use this function using fixed values. I need an example that uses variables that are holding the data to be written.
I have tried using a format such as the following:

CComSafeArray ItemDWArray(12);
ItemDWArray.SetAt(0, CComVariant(*(DWORD*)&m_sTfn1WriteCommandData.sData0));
.........

However, this generates an exception at runtime. I need help.
