FIX: #Import Does not Include Index Parameter Error from VC5

ID: Q173850

The information in this article applies to:

Collaboration Data Objects (CDO), version 1.1

SYMPTOMS

When using Microsoft Visual C++ 5.0 to import the Olemsg32.dll library, the GetItem declaration (created in the generated TLH and TLI files) in any collection-oriented object, such as Infostores or AddressLists, does not contain any index parameters; thereby, rendering these methods useless from Visual C.

RESOLUTION

The rest of the library is functional, and normally there is an alternative process to achieve the same result. For instance, you might cycle through the collection of items.

Since this was corrected in Collaboration Data Objects (CDO), version 1.2, you should consider upgrading to this version.

STATUS

Microsoft has confirmed this to be a problem in Collaboration Data Objects (CDO), version 1.1. This problem was corrected in Collaboration Data Objects (CDO), version 1.2.

MORE INFORMATION

Here's the pertinent Visual C++ 5.0 code:


    #import <olemsg32.dll> no_namespace

Here are sample declarations from generated TLI demonstrating problem:


   #pragma implementation_key(43)
   inline _variant_t InfoStores::GetItem ( ) {
       VARIANT _result;
       _com_dispatch_propget(this, 0x15, VT_VARIANT, (void*)&_result);
       return _variant_t(_result, false);
   }

-or-


   #pragma implementation_key(66)
   inline _variant_t AddressLists::GetItem ( ) {
       VARIANT _result;
       _com_dispatch_propget(this, 0x15, VT_VARIANT, (void*)&_result);
       return _variant_t(_result, false);
   }
