Timer control/ Threading/Backgroundworker

The code below loops through all the records and checks if Allocation_Due_Date is equal to the current date. If a match is found, the tooltip displays it on a button on the form. My problem is a time will come and the records will be many which will cause the machine to hang. So if someone can help me place the below code in a thread to free the machine from hanging. Thank you

' The sub procedure 'AllocationExpiryDate' is called to the Tick event of the timer control.

Public Sub AllocationExpiryDate()
Dim SQLCon As New SqlConnection : Dim dtTable As New DataSet
strUsername = GetSetting("Allocation", "Connection", "DataL1")
strPassword = GetSetting("Allocation", "Connection", "DataL2")
strServerName = GetSetting("Allocation", "Connection", "DataL3")
strInitialCatalog = GetSetting("Allocation", "Connection", "DataL4")
DataL1 = strUsername & strPassword & strServerName & strInitialCatalog
SQLCon.ConnectionString = DataL1
Dim Query As String = "Select * from Alloc order by Allocation_Due_Date asc"
daAdapter = New SqlDataAdapter(Query, SQLCon)
daAdapter.Fill(dtTable, "Alloc")
Dim table As DataTable = dtTable.Tables("Alloc")
If table.Rows.Count > 0 Then
Dim ctr As Integer
For ctr = 0 To table.Rows.Count - 1
Dim dtAllocExpDate = FormatDateTime(table.Rows(ctr).Item("Allocation_Due_Date").ToString.Trim, DateFormat.ShortDate)
If dtAllocExpDate = Now Then Then
frmMainForm.ToolTip1.Show("Allocation note is due for revision. Refer to the allocation list", frmMainForm.btnExpiry)
End If
End If
Catch ex As Exception
End Try
End Sub
