Sandeep,

 

I just read your mail and recalled that I had such similar problem before and Peter helped me to write a piece of code which can make the connection between reference ports. Thanks God that I can retrieve it from the VSS history. Here is the code and how to use it, hope it could give you some help.

 

bool CInvoke::UpdateSubscribe(CBuilderObject *pubPort,CBuilderModel *eventType, CBuilderConnection *subscribe)

{ 

      CBuilderObject *subPort = subscribe->GetDestination();

      CComponentType *subCom = GetComponent(subPort);

 

      const CBuilderModel *sprocessor = GetProcess(subCom)->GetParent();

 

      if(sprocessor!= receptacleProcess->GetParent()) return false;

      

      CBuilderModelReference *subCom_ref = NULL;

      CBuilderModelReference *event_ref = NULL;

      

      if(!shortcutMap.Lookup(eventType, event_ref))

      {

            event_ref = MakeNewEventChRef(eventType);

            shortcutMap[eventType] = event_ref;

      }

      if(!shortcutMap.Lookup(subCom, subCom_ref))     return false;

 

      MakeNewConnection("Subscribe",event_ref,subCom_ref,eventType,subPort);

      return true;

}

 

template<class SrcCls, class DstCls> 

void CInvoke::MakeNewConnection(CString connType, SrcCls *srcObj, DstCls *dstObj, CBuilderObject *srcPort,CBuilderObject *dstPort)

{

      CComPtr<IMgaSimpleConnection> mgaConn;

      CComPtr<IMgaFCOs> srcrefs, dstrefs;

 

      srcrefs.CoCreateInstance(OLESTR("Mga.MgaFCOs"));

      dstrefs.CoCreateInstance(OLESTR("Mga.MgaFCOs"));

      COMTHROW(srcrefs->Append(srcObj->GetIObject()));

      COMTHROW(dstrefs->Append(dstObj->GetIObject()));

 

      CComPtr <IMgaModel> mgaIM = newIM->GetIModel();

      CComPtr <IMgaMetaModel> metaIM;

      COMTHROW(newIM->GetMeta().QueryInterface(&metaIM));

      CComBSTR connMetaName(connType);

      CComPtr <IMgaMetaRole> metaConnRole;

      COMTHROW(metaIM->get_RoleByName(connMetaName, &metaConnRole));

      CComPtr<IMgaFCO> mgaSimpleConn;

      COMTHROW(mgaIM->CreateSimpleConn(metaConnRole, srcPort->GetIObject(),

                        dstPort->GetIObject(), srcrefs, dstrefs, &mgaSimpleConn));

}

Thanks Endre, 

I traced thru the CreateNewConnection function, and what I could tell was that a call to CreateCollection (which is a function on the IFCO interface) was not doing what it should have done, even though the result reported was success. I could not quite figure out how else to create such a collection. I looked in your code and saw that you use "CreateInstance" function, however there is no such function for the CComPtr class which BON uses.

 

Anyhow for the time-being I fixed my problem by using instances, instead of references, since no brave GME soul responded till yet.

 

Thanks

Sandeep

I had this problem with UDM,I think the connection itself is between 

atoms/models and when setting up the connection you have to provide the 

list of reference ports, through the connection is established.

 

I have the following code snipplet in UDM:

 

IMgaSimpleConnectionPtr conn; //the connection

IMgaFCOsPtr src_references;         //the list of references through the 

connecting source

IMgaFCOsPtr dst_references;         //the list of references through the 

connecting destination

 

COMTHROW(conn->SetSrc(src_references, self));

COMTHROW(conn->SetDst(dst_references, self));

 

 

This is not BON code, but that should be similar.

 

 

Hope this helps,

Endre
