C++ Sessions listing

[m.marek]

Hello all,

My task is to get the list of all openned sessions.
I need to know the parts and assemblies NAMES and file paths (if saved).
Is there any existing example code for C++ develpment.

Note:
I dont't have an "Item" object when using C++.
objRoot.Sessions.Items(1)

Here is a snippet of a sessions iterator (in C++), you need to use the root object that you get from the COM hook ...

IADSessionPtr CAddOnInterface::GetSessionFromIdentifier(/*[in]*/ BSTR sessionIdentifier)
{
    IADSessionPtr pSession = NULL;

    IADSessionsPtr pSessions = theApp.m_pRoot->GetSessions();
    if (pSessions != NULL)
    {
        if (pSessions->GetCount() > 0)
        {
            IEnumVARIANTPtr pEnumSessions = pSessions->GetEnumerator();
            ULONG fetched;
            _variant_t var;
            HRESULT res = pEnumSessions->Next(1, &var, &fetched);
            while (SUCCEEDED(res) && fetched > 0)
            {
                pSession = (IADSessionPtr)var;
                BSTR id = (BSTR)pSession->GetIdentifier();
                if (wcscmp(id, sessionIdentifier) == 0)
                    return pSession;
                else
                    res = pEnumSessions->Next(1, &var, &fetched);
            }
        }
        pSessions = NULL;
    }
    return NULL;
}

Just use pSession to drill down through its members and get the info you need.

What you show, looks like VB to me !

Thank you for your reply, yes it was an example VB code.

I'll try your code, but temporary I testes this solution and it sems to work:

int count;
VARIANT Myindex;


Root->Sessions->get_Count( &count);

for(int i=0 ; i<count ; i++)
{
Myindex.lVal = i; //session index
Myindex.vt = VT_I4;
Root->Sessions->get_Item( Myindex , iSession);
NAME = iSession->Name;
}

Your code was better.
My code freezes the thread when accesing the BOM or Drawing session type. Don't know why.
