Thanks

Hi Doug,
Would greatly appreciate it if you (or anyone) could provide a little insight about what I'm missing.
The goal is to have sockets in TestStand waiting for the Notifications to be set by CVI code. 
Environment:  Windows XP, TestStand 4.1, and LabWindows CVI 8.5.
For starters to see what works, I created a Notification named "HOLD" inside a sequence and
passed "ThisContext" to a function (SetNotify) in a CVI dll.
Upon execution of   Hr = TS_EngineGetSyncManager (seqContextCVI, &ErrInfo, "HOLD", &SyncMgrObj)
Hr is set to {0x80004002 = "No such interface supported"}
Here is my test code:
void __declspec(dllexport) __cdecl  SetNotify (CAObjHandle seqContextCVI)
   ERRORINFO      ErrInfo;
   CAObjHandle      hDataPropObj;
   CAObjHandle      hSyncMgr;   
   LPUNKNOWN    SyncMgrObj;
   VARIANT            SyncMgrVar;
   HRESULT           Hr;
    Hr = TS_EngineGetSyncManager (seqContextCVI, &ErrInfo, "HOLD", &SyncMgrObj);
    SyncMgrVar = CA_VariantIUnknown (SyncMgrObj);  
    CA_VariantConvertToType (&SyncMgrVar, CAVT_OBJHANDLE, &hSyncMgr);
     Hr = TSSyncLib_INotificationSetEx (hSyncMgr, NULL, hContext, hDataPropObj, VFALSE, VFALSE);
