WinCE 条码扫描器 - 初始化 CCoreScannerClass 时出现 COM 异常 [英] WinCE barcode scanner - COM Exception when initializing CCoreScannerClass

问题描述

我正在关注本教程(https://atgsupportcentral.motorolaso​​lutions.com/content/emb/docs/manuals/14978403a.pdf)，创建了一个简单的 Windows 窗体并成功地可以在扫描仪上调试它(它是一个 Symbol MC3000).但是，在尝试初始化 CCoreScannerClass 时出现异常:

//实例化CoreScanner类CCoreScannerClass cCoreScannerClass = new CoreScanner.CCoreScannerClass();

确切的错误信息是这样的:

由于以下错误，无法创建具有 CLSID '{9F8D4F16-0F61-4A38-98B3-1F6F80F11C87}'的 COM 对象:0x80040154."

有人可以提供一些帮助吗?既然是 COM 异常，我认为是因为该类未注册?有关如何解决此问题的任何想法?

非常感谢.

解决方案

我通过从摩托罗拉网站下载 .NET EMDK 使其工作:

https://atgsupportcentral.motorolasolutions.com/content/emb/docs/manuals/14978403a.pdf), created a simple Windows Forms and successfully can debug it on the scanner (it's a Symbol MC3000). However I am getting an exception when trying to initialize the CCoreScannerClass:

        //Instantiate CoreScanner Class
        CCoreScannerClass cCoreScannerClass = new CoreScanner.CCoreScannerClass();

The exact error message is this:

"COM object with CLSID '{9F8D4F16-0F61-4A38-98B3-1F6F80F11C87}' cannot be created due to the following error: 0x80040154."

Can anyone please provide some help? Since it's a COM exception, I assume it's because the class is not registered? Any ideas on how to fix this?

Many thanks.

解决方案

I got it working by downloading the EMDK for .NET from the Motorola's website:
