Results From Stored Procedure Inset

I am having trouble getting data back from my stored procedure insert commands.  Here is what I currently have set up.

1 - A dataset called YagDag

2 - A Table adapter called tadUsers

3 - A Stored Procedure that the tadUsers uses to insert called spUser_i

It seems like the way I have my VB code set up I can only retrieve a return int. I can't figure out how to get my User GUID back, any help would be really appreciated

  Public Shared Function AddUser(ByVal EMail As String, ByVal FirstName As String, ByVal LastName As String, ByVal Password As String, ByVal EMailActive As Boolean) As Integer
Dim strEMail = AppFunction.SQLSafeString(EMail)
Dim strFirstName = AppFunction.SQLSafeString(FirstName)
Dim strLastName = AppFunction.SQLSafeString(LastName)
Dim strPassword = AppFunction.SQLSafeString(Password)
Dim blnEMailActive = EMailActive

Dim Users As New YagDagTableAdapters.tadUsers

Dim guidUserYID As Guid = Users.Insert(strFirstName, strLastName, strPassword)

Return 1
