  1. Hi guys!

    My newly built website has just recently went online,

    but sometimes I face errors (randomly) like these:

    System.IndexOutOfRangeException: There is no row at position 0.
    System.InvalidOperationException: There is already an open DataReader
    associated with this Command which must be closed first.
    System.IndexOutOfRangeException: Cannot find table 0

    System.NullReferenceException: Object reference not set to an instance of an

    System.InvalidOperationException: ExecuteNonQuery requires an open and
    available Connection. The connection's current state is closed.

    System.InvalidOperationException: Internal connection fatal error.

    I use a dbmanager class as a wrapper for db ,

    which I uploadere here:

    The strange thing is that both iis and the database lie on the same machine,

    but I use tcp/ip for incoming connections,


    could anyone help me get rid of these errors somehow?

    thanks in advance!
