Hi everyone,

Does anyone have any idea on how to call web method on asp.net web page? I am trying on calling web method on a web page. Currently, I have tried calling the web method on C# Web Form, but i need to do this on asp.net web page. The following is my code on web method and C# web application.

private void button3_Click(object sender, EventArgs e)
{
            RequestWS.Service rWS = new RequestWS.Service();
            int result = rWS.DoIT();

            if (result > 0)
            {
                MessageBox.Show("YES! WE ARE SUCEEDDED!");

            }
            else
            {
                MessageBox.Show("Invalid IpAddress");
            }
 }

    [WebMethod]
    public int DoIT()
    {

        // Get the hostname 
        string myHost = System.Net.Dns.GetHostName();

        string connect = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source=c:\\inetpub\\wwwroot\\RequestWS\\App_Data\\TV.mdb";
        string query = "SELECT COUNT(IPAddress) FROM Request WHERE IPAddress = ?";
        int result = 0;

        using (OleDbConnection conn = new OleDbConnection(connect))
        {
            using (OleDbCommand cmd = new OleDbCommand(query, conn))
            {
                cmd.CommandType = CommandType.Text;
                cmd.Parameters.AddWithValue("IPAddress", myHost);

                conn.Open();
                result = (int)cmd.ExecuteScalar();
            }
        }
        
        return result;

    }
