-# Internet Explorer creating offline sites #-

I'm trying to create a offline site using the ISubscritpionMgr interface. The site should be synchronized every 12 hours.
I currently got stucked with the code below - I always get an "invalid parameter" error. I've no idea why.

void CSubscriptionMgr::SubcribeURL(CString strURL, CString strFiendlyName, TASK_TRIGGER_TYPE Interval, TRIGGER_TYPE_UNION IntervalSettings, int iStartHour, int iStartMinute)
{
     HRESULT hr;
     BSTR bstrURL;
     BSTR bstrName;
     SUBSCRIPTIONINFO sinfo;
    TASK_TRIGGER trig;
     SYSTEMTIME st;
     
     memset(&sinfo, 0, sizeof(sinfo));
     sinfo.cbSize = sizeof(sinfo);
     memset(&trig, 0, sizeof(trig));
     trig.cbTriggerSize = sizeof(trig);
     
     bstrURL = strURL.AllocSysString();
     bstrName = strFiendlyName.AllocSysString();

// Fill in current local date and time
     GetLocalTime(&st);
     trig.wBeginYear = st.wYear;
     trig.wBeginMonth = st.wMonth;
     trig.wBeginDay = st.wDay;
     trig.wStartHour = iStartHour;
     trig.wStartMinute = iStartMinute;
     trig.TriggerType = Interval;
     trig.Type = IntervalSettings;

     sinfo.fUpdateFlags = SUBSINFO_SCHEDULE | SUBSINFO_RECURSE | SUBSINFO_WEBCRAWL | SUBSINFO_TASKFLAGS | SUBSINFO_GLEAM | SUBSINFO_FRIENDLYNAME | SUBSINFO_NEEDPASSWORD | SUBSINFO_TYPE;
     sinfo.schedule = SUBSSCHED_WEEKLY; //SUBSSCHED_CUSTOM;
     sinfo.pTrigger = &trig;
     sinfo.dwRecurseLevels = 3;
     sinfo.fWebcrawlerFlags = WEBCRAWL_GET_IMAGES & WEBCRAWL_GET_VIDEOS & WEBCRAWL_GET_BGSOUNDS & WEBCRAWL_GET_CONTROLS;
     sinfo.bMailNotification = false;
     sinfo.bGleam = true;
     sinfo.bChangesOnly = false;
     sinfo.bNeedPassword = false;
     sinfo.fChannelFlags = 0; //CHANNEL_AGENT_PRECACHE_ALL;
     sinfo.bstrFriendlyName = bstrName;
     sinfo.dwMaxSizeKB = 500;
     sinfo.subType = SUBSTYPE_URL;
     sinfo.fTaskFlags = 1040; /////0000000000000
     sinfo.dwReserved = 0;
     
//     hr = pSubscriptionMgr->IsSubscribed(bstrURL, &Bool);
     hr = pSubscriptionMgr->CreateSubscription(NULL,
                                        bstrURL,
                                        bstrName,
                                        CREATESUBS_NOUI | CREATESUBS_ADDTOFAVORITES | CREATESUBS_FROMFAVORITES,
                                        SUBSTYPE_URL,
                                        &sinfo);
     SysFreeString (bstrURL);
     SysFreeString (bstrName);
     CheckHResult(hr);
