I am trying to execute the bewlo SP when the button1_click
occured, but I am geeting an error in CATCH statment and the number from daabase is not shown in the text box.

The error I am getting: when casting from number, the value must be a numbe less than infinity. Make sure the source type is convertible to the destination type.


public static int Acute_Treatment(int year, int month, string unit_abbr)
    {

        string connectionString = ConfigurationManager.ConnectionStrings["Finance_AppsConnectionString"].ConnectionString;
        System.Data.IDbConnection dbConnection = new System.Data.SqlClient.SqlConnection(connectionString);

        System.Data.IDbCommand dbCommand = new System.Data.SqlClient.SqlCommand();
        dbCommand.CommandText = "usp_Acute_Treatment";
        dbCommand.CommandType = CommandType.StoredProcedure;
        dbCommand.Connection = dbConnection;


        System.Data.IDataParameter dbParam_year = new System.Data.SqlClient.SqlParameter();
        dbParam_year.ParameterName = "@year";
        dbParam_year.Value = year;
        dbParam_year.DbType = System.Data.DbType.Int32;
        dbCommand.Parameters.Add(dbParam_year);



        System.Data.IDataParameter dbParam_month = new System.Data.SqlClient.SqlParameter();
        dbParam_month.ParameterName = "@month";
        dbParam_month.Value = month;
        dbParam_month.DbType = System.Data.DbType.Int32;
        dbCommand.Parameters.Add(dbParam_month);

        System.Data.IDataParameter dbParam_unitabbr = new System.Data.SqlClient.SqlParameter();
        dbParam_unitabbr.ParameterName = "@unit_abbr";
        dbParam_unitabbr.Value = unit_abbr;
        dbParam_unitabbr.DbType = System.Data.DbType.String;
        dbCommand.Parameters.Add(dbParam_unitabbr);
       

        int result = 0;

        try
        {
            dbConnection.Open();
            result = (int)dbCommand.ExecuteScalar();
        }
        catch
        {

        }


        finally
        {
            dbConnection.Close();
        }


        return result;


    }


  protected void Button1_Click(object sender, EventArgs e)
    {

        int month = Convert.ToInt32(DropDownList1.SelectedValue);
        int year = Convert.ToInt32(DropDownList2.SelectedValue);
        string unit_abbr = Convert.ToString(DropDownList3.SelectedValue);



        Acutetxt.Text = Convert.ToString(ActuteTreatments.Acute_Treatment(year, month, unit_abbr));

if the error is in this line: result = (int)dbCommand.ExecuteScalar();

then make a break point in it and verify what value is the stored returning
