Continuous queue

What im trying to do is create a logging queue that i can just enqueue items to when i need to and it will process the items in order of the item been queued. basically i want to be able to call something like

queue.enque("Some Sql query")

Select allOpen in new window

and it will then process the SQL query when it has the resources to do so. What i have at the moment is:

The queue:

 Public Class SQLQueueManager
        Public Shared Sqlitems As New Queue

        Public Sub StartProcessing()
            Dim t1 As New Threading.Thread(AddressOf Process)
            t1.Start()
        End Sub

        Public Shared Sub Process()
            Do
                SyncLock Sqlitems.SyncRoot
                    If Sqlitems.Count = 0 Then

                    ElseIf Sqlitems.Count > 0 Then
                        SqlManager.ExecNonQuery(Sqlitems.Peek)
                        Sqlitems.Dequeue()
                    End If
                End SyncLock
            Loop
        End Sub

    End Class

Select allOpen in new window

Calling the enqueue:

 Public Shared Sub InsertLog(ByVal dateAndTime As String, ByVal classStr As String, ByVal methordStr As String,
                                    ByVal logType As String, ByVal message As String)
            SQLQueueManager.Sqlitems.Enqueue(
                "Insert log SET DateAndTime =NOW() ,Class ='" & classStr & "' ,Methord ='" & methordStr &
                "' ,LogType ='" & logType & "' ,Message ='" & message & "' ")
        End Sub

Select allOpen in new window

Starting the queue:

Dim sqlT As Thread = New Thread(AddressOf SQLQueueManager.Process)
sqlT.Start()

Select allOpen in new window

Im not sure if this is the best way to do this, As this is a application that is going to be constantly running and using this queue I'm not sure if it would be up to doing what i need it to do.

Thanks for your help,
