Problems dereferencing a variant

[Manny Bonet]

I downloaded some code from MSDN to allow the upload of a
file from an ASP page. I know that .NET can do this in an
easire fashion but converting all the code would just be
too much of a pain in the butt. The code works fine and I
can upload a file however when it processes the form it
does not expose the names (which it stores as a key in a
stl::map and also in a stl::set) of the input items it
loads into the CDictionary class. When I try to
dereference the key in the set I get a failure in the ASP
page. Here is the code;
typedef std::map<CComVariant, CComVariant> OurMap;
typedef std::set<CComVariant> CComVariantList;
OurMap m_map;
CComVariantList m_keys;

This is the function to return the value it works
STDMETHODIMP CDictionary::get_Item(VARIANT *key, VARIANT
*pVal)
{
if ((key->vt & ~VT_BYREF) != VT_BSTR) return
E_POINTER;

CComVariant varKey(*key);

OurMap::iterator theIterator = m_map.find(varKey);

if(theIterator == m_map.end()) {
VariantInit(pVal);
} else {
VariantCopy(pVal, &(*theIterator).second);
}
return S_OK;
}
This is my new function to return the key it does not work.
STDMETHODIMP CDictionary::get_Key(long idx, VARIANT *pVal)
{

//if ((key->vt & ~VT_BYREF) != VT_BSTR) return
E_POINTER;

//CComVariant varKey(*key);

CComVariantList::iterator i;
long j = 0;

for (i = m_keys.begin(); i != m_keys.end(); i++){
j++;
if (j == idx){

CComVariant varI = *i;

varI.Detach(pVal);

}
}

return S_OK;
}

I know that iterating through all of the elements in the
set to find a specific one to return is not the right way
but I don't have time nor the experties to write the
IDispatch Code and enum to allow the collection of keys to
be exposed so you can use a for each on it. can anybody
help?
