类未注册HRESULT [英] Class Not Registered HRESULT

问题描述

所以当我尝试打开一个Form时出现这个错误...这很精细，我知道为什么我会收到错误。

So I'm getting this error when I try to open a Form...which is FINE, I know why I'm getting the error.

因为那个COM组件未安装在该计算机上，但是我想要尝试在Try Catch中捕获此错误，这样我就可以显示不同的错误消息。

Because that COM Component isn't installed on that machine, but want I'm trying to do is catch this error in a Try Catch so I can display a different Error Message.

Try Catch是没有在Form_Load中收到此错误，那么我应该使用Try Catch来捕获此错误？

The Try Catch is not picking up this error in Form_Load, so which event should I put the Try Catch to capture this error?

谢谢，

Mark

如果您下载源代码，它也有一个VB.NET示例 您可以在项目中实现，并且您不需要在代码中的任何位置使用try / catch，并让全局或集中式异常处理程序捕获异常。

If you download the source code, it has a VB.NET example too  that you can implement in your project, and you don't need a try/catch anywhere in the code and let the global or centralized exception handler catch the exception.
