sap crystalreport c＃add-on logonfailed

Question

我也试图解决这个问题太困难了我尝试使用c＃在visualstudio 2010中直接打印我的sap插件中的值，它为我返回了这个错误： ＆＃39; logonfailed＆＃39;这是我的代码：

try
        {
            DataTable matable = new DataTable();
            DataSet madataset = new DataSet();
            SqlConnection maconnexion = new SqlConnection();

            maconnexion.ConnectionString = Menu.connectionString_formatsql;
            SqlCommand cmd = new SqlCommand();

            cmd.CommandText = "select oitm.ItemCode ,OITM .ItemName ,OITM .CodeBars,ITM1.Price,@codebars " +
                      " from OITM,ITM1 where OITM .ItemCode=ITM1 .ItemCode" +
                      " and OITM.ItemCode =@itemCode" +
                      " and ITM1 .PriceList = @pricelist  ";

            cmd.Parameters.Clear();

            //cmd.Parameters.Add("@codebars", SqlDbType.VarChar );
            //cmd.Parameters["@codebars"].Value = get_codebarre_dessin();

            //cmd.Parameters.Add("@itemCode", SqlDbType.VarChar);
            //cmd.Parameters["@itemCode"].Value = this.EditText1.Value;

            //cmd.Parameters.Add("@pricelist", SqlDbType.SmallInt);
            //cmd.Parameters["@pricelist"].Value = Convert.ToInt32(this.ComboBox0.Value);

            cmd.Parameters.Add("@codebars", SqlDbType.VarChar);
            cmd.Parameters["@codebars"].Value = get_codebarre_dessin();

            cmd.Parameters.Add("@itemCode", SqlDbType.VarChar);
            cmd.Parameters["@itemCode"].Value = this.EditText1.Value;

            cmd.Parameters.Add("@pricelist", SqlDbType.Int);
            cmd.Parameters["@pricelist"].Value = Convert.ToInt32(this.ComboBox0.Value);

            cmd.Connection = maconnexion;

            if (maconnexion.State == ConnectionState.Closed)
