Hi,

I am working with a web application with MySQL as the backend in asp.net. I need to insert values in a table called ACS. The code is working fine and i am able to insert values. But the problem i am facing is the values are getting stored as dupliate ones. I have enclosed the code that i have used.

My ACS_Details.aspx page

My Codebehind page

Imports System.Data.Odbc
Imports System.IO
Imports MySql.Data.MySqlClient

Partial Class Company
    Inherits System.Web.UI.Page

    Protected Sub bttnInsertRecord_Click1(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles bttnInsertRecord.Click
        Dim ConnString As String = ConfigurationManager.ConnectionStrings("UKGasConnString").ConnectionString

        Using con As New OdbcConnection(ConnString)
            con.Open()
            Using cmd As New OdbcCommand("INSERT INTO tbl_ACS" & "(ACS, Description) VALUES (?,?)", con)
                cmd.Parameters.Add("@ACS", OdbcType.VarChar, 255).Value = txtACS.Text.Trim()
                cmd.Parameters.Add("@Description", OdbcType.VarChar, 255).Value = txtDescription.Text.Trim()
                cmd.ExecuteNonQuery()
            End Using
        End Using
    End Sub
End Class

The ConnectionString

<connectionStrings>  <add name="UKGasConnString" connectionString="Driver={MySQL ODBC 5.1 Driver};Server=localhost;Port=3306;Database=db_UKGas;Uid=root;Pwd=password;pooling=false;"   providerName="MySql.Data.MySqlClient" /> </ connectionStrings>

I am really in need of help in this. I need to complete this project for my college work. Looking forward for your help in this.

By isn't karth saying that values are getting stored twice? His problem, as I read it, isn't getting double values returned but getting repeat values inserted.
