霍尼韦尔条码扫描器问题 [英] Honeywell barcode scanner issue

问题描述

大家好，

我遇到霍尼韦尔条码扫描器（Voyager 1250g）的问题。将扫描仪连接到PC后，我安装了霍尼韦尔POS4NET套件1.13.3.13。有了它，就安装了Microsoft POS for .NET 1.12。我试图运行TestApp.exe，它甚至显示
霍尼韦尔扫描仪的多个实例（似乎扫描仪同时在键盘和HID模式下工作+只是通过COM1端口连接的空扫描仪）。它们都无法打开。

I have a problem with Honeywell barcode scanner(Voyager 1250g). After I have attached the scanner to PC, I have installed Honeywell POS4NET Suite 1.13.3.13. With it Microsoft POS for .NET 1.12 was installed. I tried to run TestApp.exe and it displays even multiple instancess of Honeywell scanners(it seems that scanner is working in Keyboard and HID mode simultaneously + just empty scanner connected via COM1 port). None of them could not be even opened.

我通过POS4HET配置实用程序添加实例后尝试与POS4NET进行交互：

I've tried to interact with scanner with POS4NET after adding an instance via POS4HET Configuration Utility:

            _scanner = new HandHeldScanner（）;

            _scanner.DataEvent + = scanner_DataEvent;
$


            if（_scanner.State == ControlState.Closed）

            {

                _scanner.AssignLogicalname =" HoneywellVoyager1250g";

                _scanner.Open（）;

            }




            if（_scanner.Claimed == false）

            {

                _scanner.Claim（10000）;

            }

            _scanner = new HandHeldScanner();
            _scanner.DataEvent += scanner_DataEvent;

            if (_scanner.State == ControlState.Closed)
            {
                _scanner.AssignLogicalname = "HoneywellVoyager1250g";
                _scanner.Open();
            }


            if (_scanner.Claimed == false)
            {
                _scanner.Claim(10000);
            }

代码在带有PosControlException的_scanner.Claim行上失败：无法声明设备和非法错误代码。

The code is failing on _scanner.Claim line with PosControlException: Unable to Claim Device and Illegal error code.

注意，扫描程序工作正常如果我将焦点设置为文本区域。如果我从霍尼韦尔运行EZConfig网络应用程序，它也有效。即使没有焦点，它也会挂钩扫描数据。

Note, that scanner works fine if I set focus to text area. It also works if I run EZConfig web app from Honeywell. It hooks scanned data even without focus.

谢谢，

推荐答案

看起来不对劲。 HandHeldScanner（）来自哪里？您是否正在尝试构建现代应用程序或表单应用程序？ POS for .NET 1.12适用于表单应用程序。以下是我的一个表单应用程序示例中的代码：

Something doesn't look right. Where is HandHeldScanner() coming from? Are you trying to build a Modern App or a Forms App? POS for .NET 1.12 is for Form apps. Here is the code from one of my book examples for Form application:

 myScanner = (Scanner)myPosExplorer.CreateInstance(device);
 myScanner.Open();
 myScanner.Claim(1000);
 myScanner.DataEvent += new DataEventHandler(myScanner_DataEvent);
 myScanner.DeviceEnabled = true;
 myScanner.DataEventEnabled = true;
 myScanner.DecodeData = true;
