i have tried all sorts of combinations to resolve it ....am i being stupid and maybe it isn't possible to get the data from a textbox for a query? all i'm trying to do is count how many files a member has uploaded?

look forward to your answers thanks
andy

You have to add a parameter.

Protected Sub recordcount_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles recordcount.Click
        Dim con As New Data.SqlClient.SqlConnection()
        con.ConnectionString = ConfigurationManager.ConnectionStrings()("ConnectionString").ConnectionString

        Dim cmd As New Data.SqlClient.SqlCommand()
        cmd.CommandText = "select count (*) from images where  userid=@Userid"
        cmd.CommandType = Data.CommandType.Text
        cmd.Connection = con

        cmd.Parameters.AddWithValue("@Userid","a0001")
        con.Open()
        Dim result as integer = cmd.ExecuteScalar()
        con.Close()
        If result > 0 Then
            count.Text = result

            If result < 0 Then
                MsgBox(result)
            End If
        End If
   End Sub

Thanks for taking the time to look at this for me. i tried what you said with the a in front of userid it throws up....""""Conversion failed when converting the nvarchar value 'a0001' to data type int.""". If i remove the a then it counts the files but only the ones that relate to whatever the last digits are..eg... at the moment id 1 has 3 records so it reads 3.....if i change it to "0099" then it shows 1 record for id number 99 which is correct but it will only change the count after reloading the page.. which means half of it is working but i need to be able to type any id number in the textbox "userid" and count them records.. look forward to your reply many thanks andy

cmd.Parameters.AddWithValue("@Userid",Userid.Text)

that is fantastic thanks so much you've been a big help
