Hi

I have a class which freezes my application when it is doing its thing!

All the class does is query a database and returns a datatable e.g.

----------code-----------
Option Strict On

Imports System.Data
Imports System.Data.SqlClient

Public Class OriginalData

    Dim objDataSet As DataSet
    Dim objSQLConnection As SqlConnection
    Dim objSQLDataAdapter As SqlDataAdapter

    ReadOnly Property TheData(ByVal myquery As String) As DataTable
        Get
            TheData = TheQuery(myquery)
        End Get
    End Property

    Private Function TheQuery(ByVal myQuery As String) As DataTable
        objSQLConnection = New SqlConnection("the connection string here")
        objSQLDataAdapter = New SqlDataAdapter(myQuery, objSQLConnection)
        objDataSet = New DataSet

        objSQLDataAdapter.Fill(objDataSet, "tblOriginal")

        Return objDataSet.Tables("tblOriginal")
    End Function

End Class
----------end code-----------

and I use it like this:

---------code------------

objDataTable = objOriginalData.TheData("sql query in here")

----------end code-----------

How do I "MultiThread" this so it does not freeze the application?

Thanks
