Have to loop through one data reader and check another data reader at the same time but get error!

Please note image attachment below of error highlighting line: Dim reader2 As SqlDataReader = command2.ExecuteReader().

I get error message of there is already an open DataReader associated with this command which must be closed first.

I really only have command not command2 opened - so I don't know why the message.  Probably saying I can't have two datareaders opened at the same time.  I don't want to know why this is happening but rather how may I rewrite the code so that this can work?

Basically I have a base table (AllPrograms) full of programs' full path names to check to see if they exist on a person's machine in a log table (LogProgramID).  If it exists already then merely check the datemodified field and make sure its the same - if not then get it updated.

 Dim command As SqlCommand
        Dim command2 As SqlCommand
        Dim command3 As SqlCommand

            sSQL = sSQL & " ORDER BY [ProgramFullName]"
            command = New SqlCommand(sSQL, connection)
            reader = command.ExecuteReader()
            While reader.Read()

                lProgramID = reader(0).ToString
