Quickbooks POS SDK很奇怪btnHelp BeginSession错误

Question

我试图通过Quickbooks POS SDK将C＃程序与Quickbooks POS集成。我安装了Quickbooks，Quickbooks SDK，Quickbooks POS和Quickbooks POS SDK。

当以下代码命中“sessionManager.BeginSession（”“）;”时我收到错误消息“错误读取btnHelp.BorderColorSelected：Property BorderCo”。不是一个错字，它以BorderCo结束。

有人请帮忙！

        private void CustomerAdd()
        {                        
            QBPOSSessionManager sessionManager = new QBPOSSessionManager();

            IMsgSetRequest request = sessionManager.CreateMsgSetRequest(3, 0);
            request.Attributes.OnError = ENRqOnError.roeContinue;
            BuildItemInventoryAddRq(request);
            sessionManager.OpenConnection("appID", "Application");
            sessionManager.BeginSession("");
            IMsgSetResponse response = sessionManager.DoRequests(request);
            sessionManager.EndSession();
            sessionManager.CloseConnection();
        }

        private void BuildItemInventoryAddRq(IMsgSetRequest request)
        {
            IItemInventoryAdd ItemInventoryAddRq = request.AppendItemInventoryAddRq();
            ItemInventoryAddRq.ALU.SetValue("M9ine");
        }

        private void button1_Click(object sender, EventArgs e)
        {
            CustomerAdd();
        }
    }
}

Answer 1

我不确定您是否还需要答案，但可能需要在sessionManager.BeginSession（）方法中设置连接字符串：

string connectionString = "Computer Name=WORKPC;Company Data=YourQBCompany;Version=10";
sessionManager.BeginSession(connectionString)

请参阅QB POS SDK开发指南，特别是使用Begin Session方法：http://dev.developer.intuit.com/POSSDK-Current/doc/pdf/QBPOS_ProgramGd.pdf
