GetSpellingSuggestions fails with custom dictionary

[Chris Hinton]

I am running into an issue with the GetSpellingSuggestions method. If I call
it without specifying a custom dictionary, the call works find and returns a
list of words as expected. However, if I provide the path to a custom
dictionary it fails with an HR of 0x800a239d (which I can find no reference
to anywhere).

Here is the code that displays the error... If I make the 'dictionary'
variant vtMissing, the GetSpellingSuggestions works perfectly. Anybody have
any suggestions (pun intented)...

STDMETHODIMP CSpellChecker::GetSpellingSuggestions
(
BSTR word,
BSTR customDictionary,
ISpellingSuggestions **suggestions
){
HRESULT returnValue;
MSWord::_ApplicationPtr spellChecker = _Module.getMSWordApplication();

if( NULL == spellChecker )
{
returnValue = E_UNEXPECTED;
}
else if( NULL == word ||
NULL == suggestions )
{
returnValue = E_POINTER;
}
else
{
try
{
_variant_t ignoreUppercase( m_ignoreUppercase );
_variant_t dictionary = validateCustomDictionary(
customDictionary ) ? _variant_t(customDictionary) : vtMissing;

MSWord::SpellingSuggestionsPtr sug =
spellChecker->GetSpellingSuggestions( word, &dictionary, &ignoreUppercase );

CSpellingSuggestions * cSug = new CComObject<CSpellingSuggestions>;

cSug->SetSuggestions( sug );

*suggestions = cSug;
(*suggestions)->AddRef();

returnValue = S_OK;
}
catch( const _com_error & e )
{
_bstr_t message( e.ErrorMessage() );
_bstr_t desc( e.Description() );
OutputDebugString( e.ErrorMessage() );
OutputDebugString( "\n" );

returnValue = E_FAIL;
}
}

return( returnValue );
}

Just a little follow up information. Elsewhere, I have a call to
CheckSpelling that works perfectly well with the custom dictionary parameter.
That is, it does not flag words that are in my custom dictionary as
misspelled.

This code works without error:
_variant_t ignoreUppercase( m_ignoreUppercase );
_variant_t dictionary = validateCustomDictionary( customDictionary ) ?
customDictionary : vtMissing;
*returnValue = spellChecker->CheckSpelling( word, &dictionary,
&ignoreUppercase );
