Getting the default record type of a user for Event Creation in Salesforce

I have been twisting my head around in finding a solution for this simple task and I guess its worth while to share this information to everyone as I cannot search anything on Google or even in Developer Force any solution related to my problem. Eventually it ended up in calling their premier support for assistance, then after a week of emails sent back and forth the answer was:

“you cannot get the default record type for user without logging to salesforce.com”

what that means is that you cannot get the default record type for a user if you are using a privileged account, you must use the users login credentials when performing the query, which defeats the purpose of having a super user account creating events for you programatically.

Anyway here is what I initially done to get the default record type, At first they suggested this solution in Java

Schema.DescribeSObjectResult oSObjectResult = Event.SObjectType.getDescribe();
ListRecordTypeInfo> oRecTypeInfos = oSObjectResult.getRecordTypeInfos();

Schema.RecordTypeInfo has a method isDefaultRecordTypeMapping()

So I used that information to grab what I want in C#.Net, so I created a method to extract that information

public SforceService Authenticate()
{
    try
    {
        SforceService oSalesForceService = new SforceService();
        oSalesForceService.Timeout = 60000;

        // Set Proxy Details if you are using one
        WebProxy oWebProxy = new WebProxy(WebRequest.DefaultWebProxy.GetProxy(new Uri(oSalesForceService.Url.ToString())));
        oWebProxy.Credentials = CredentialCache.DefaultCredentials;
        oWebProxy.UseDefaultCredentials = true;
        oSalesForceService.Proxy = oWebProxy;

        //Initialize SalesForce Service
        LoginResult oLoginResult = oSalesForceService.login(sUserName, string.Concat(sPassword, sToken));

        oSalesForceService.Url = oLoginResult.serverUrl;
        oSalesForceService.SessionHeaderValue = new SessionHeader();
        oSalesForceService.SessionHeaderValue.sessionId = oLoginResult.sessionId;
        GetUserInfoResult oUserInfo = oLoginResult.userInfo;

        return oSalesForceService;
    }
    catch (Exception ex)
    {
        return null;
    }
}

public string GetRecordType()
{
    SforceService oSalesForceService = Authenticate();

    string sRecordTypeId = "";

    DescribeSObjectResult oObjectResult = oSalesForceService.describeSObject("Event");
    List<RecordTypeInfo> oRecTypeInfos = oObjectResult.recordTypeInfos.ToList();
    foreach (RecordTypeInfo oRecTypeInfo in oRecTypeInfos)
    {
        if (oRecTypeInfo.defaultRecordTypeMapping == true)
        {
            sRecordTypeId = oRecTypeInfo.recordTypeId;
        }
    }
    return sRecordTypeId;
}

Using that will be an issue as it is not showing options on filtering it by Owner ID like what SalesForce have in other tables, so the result shown after I executed the method is the default record type of the privileged Account.  So I thought I can go directly to the related tables perform SOQL queries like such

oQueryResult = oSalesForceService.query("Select Id, Name from RecordType where SobjectType = 'Event' and IsActive = True and OwnerID = '" + sOwnerID +"'");

and might have some hope in there but after checking the RecordType and RecordTypeInfo there is not field for Owner ID

and in User class there are no fields for Default record type.

So the only real solution for this as of this post date is to keep a local copy of the default record type per user or as a Global setting if you wish.   So when I create event I assign the RecordTypeId by getting it by the “Record Type Name” defaulted to a user which is stored locally.

oEvent.RecordTypeId = GetRecordTypeId(sUserDefaultRecordType);

public string GetRecordTypeId(string sRecordTypeName)
{
    SforceService oSalesForceService = Authenticate();

    QueryResult oQueryResult = null;

    oSalesForceService.QueryOptionsValue = new QueryOptions();
    oQueryResult = oSalesForceService.query("Select Id from RecordType where SobjectType = 'Event' and IsActive = True and Name = '" + sRecordTypeName + "'");

    if (oQueryResult.size != 0)
    {
        RecordType oRecordType = (RecordType)oQueryResult.records[0];
        return oRecordType.Id;
    }
    return null;
}

I hoped I helped someone out there with a similar situation as I have
