Lst = Com.AskLogDialLst("61795,3278")

STDMETHODIMP CCom::AskLogDialLst(BSTR Lst, BSTR *Result)
{
      AFX_MANAGE_STATE(AfxGetStaticModuleState());

That's not really surprising. That should be

STDMETHODIMP CCom::AskLogDialLst(BSTR Lst, BSTR *Result)
{
    AFX_MANAGE_STATE(AfxGetStaticModuleState());
    *Result = SysAllocString(L"123");
   
    return S_OK;
}

Ok, normally, "123" is content of      char *Resultchr.

If i put *Resultchr as place of "123", it give me error C3861: 'L': identifier not found, even with argument-dependent lookup
