Hi,

To make transient subscription I use the following code(VC++):

CComPtr     pCat;
CComPtr              pDispCol, pDispSub;
CComQIPtr   pCatCol;
CComQIPtr     pCatObj;
long                            nRetval;

hr = CoCreateInstance(__uuidof(COMAdminCatalog), NULL, CLSCTX_SERVER, __uuidof
(ICOMAdminCatalog), (void**)&pCat);

hr = pCat->GetCollection(L"TransientSubscriptions", &pDispCol);
pCatCol = pDispCol;
hr = pCatCol->Populate();
hr = pCatCol->Add(&pDispSub);
pCatObj = pDispSub;
//...
// setting subscription's properties (SubscriberInterface, EventClassID, etc...)
//...

hr = pCatCol->SaveChanges(&nRetval);

// .....

This code works fine within client application, BUT if I use this code within
COM+ component (say, this COM+ component would like to make transient
subscription itself) SaveChanges() on TransientSubscription collection call fails
with E_ACCESSDENIED error :(
I played with COM+ security settings,but nothing...
Also I tried to create COMAdminCatalog object using ContextObject
(CreateInstansce) - just the same...

May be somebody knows where is the problem.
Thanks in advance!

Did you try to play with the identity tab in the com+ application properties?

When you say COM+ component, are talking about an EXE or something running within IIS or what?

Okay, so your component is a DLL. How are you testing this DLL? What application are you using?
