Hi folks,

I am getting above mentioned error when I try to run the following code:

 Private strConnString As String = ConfigurationManager.ConnectionStrings("conString").ConnectionString
    Private con As New SqlConnection(strConnString)
    Private pID As Integer
'FIRST SECTION Dim query As String = "query" Dim cmd As New SqlCommand(query) cmd.Parameters.Add("@pID", SqlDbType.Int).Value =pID Using con Using sda As New SqlDataAdapter() Try cmd.Connection = con Catch ex As Exception Response.Write("Error" & ex.Message) Finally con.Close() End Try sda.SelectCommand = cmd Using ds As New DataSet() sda.Fill(ds) 'output End Using End Using End Using

'SECOND SECTION Dim cmd2 As New SqlCommand("query", con) Try con.Open() cmd2.ExecuteNonQuery() Dim reader As SqlDataReader = cmd2.ExecuteReader() While reader.Read() Dim rr As String = reader.Item("dID").ToString Dim returnedRows As String = reader.FieldCount.ToString() If rr = "True" Then 'output ElseIf rr = "False" Then 'output End If End While reader.Close() Catch ex As Exception Response.Write("error" & ex.Message) 'Error is beign displayed here: The ConnectionString property has not been initialized Finally con.Close() End Try

The error is coming from the second SQL cmd but if I comment out the first section; the second section runs fine.

I must have made another basic error but I just can't figure out what it is. Any help would be great. Thanks.

You will have to again do

con As New SqlConnection(strConnString)

before you intialize cmd2 as you are using USING which diposes the connection object

I agree, here is the link:
