************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.For example:<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.//英文实在太肉了，求救一下更新发布

错误就是这个喽:System.NullReferenceException: Object reference not set to an instance of an object.
   at NTSCallCenter.Common.HtmlEditor.HtmlEditor.webBrowserBody_DocumentFocusing(Object sender, HtmlElementEventArgs e)NTSCallCenter.Common.HtmlEditor.HtmlEditor这个是你自己的控件或者第三方的控件，webBrowserBody_DocumentFocusing函数中，使用了空引用。
这很常见，步骤，环境等等不同。软件不可能100%没有bug的。
应该是引用了第三方控件，在本地机器上注册了，解决方式在客户机上用regsvr32重新注册下应该就可以了
我看了这个方法，这边没有问题
  webBrowserBody.Document.DomDocument.GetType().GetProperty("designMode").SetValue(webBrowserBody.Document.DomDocument, "On", null);
只是让 webBrowserBody 具有编辑性
之前一直都没有问题的，好像上次增加了 excl 导出功能后就出现这个问题了
