分享如何从ASP页面中调试跟踪到VB组件中？
用VB编写ActiveX DLL组件，在ASP页面中使用，现在希望在调试ASP页面代码的过程中遇 到调用组件的相关方法的时候直接跟踪到VB开发环境中进行调试，如何能做得到？据说盖茨先生当前曾经演示过的。谢谢各位大佬！

可以引发从您的组件产生的新异常。可以添加消息字符串为开发人员提供附加信息，还可以将所有原始异常信息打包在新异常的 InnerException 属性中。这将生成一个从您的组件产生的异常，并使得客户端应用程序不知道任何正在使用的次要组件，但在需要时包含所有原始信息。下面显示了一个示例：
' Visual Basic
Try
' Calls a method in a secondary component. This call is enclosed in a
' Try block in case an exception is thrown by SecondaryComponent.
SecondaryComponent.CallMethod()
Catch e as OverflowException
' An overflow exception is caught and a new overflow exception is
' thrown to the client application. This new excpetion includes the
' original exception as the InnerException, and provides an informative
' message.
Throw New OverflowException("An overflow occurred in the xyz method", _
e)
End Try

不大行吧，你不如复杂点，在dll里多写点返回值（在各个你需要察看的地方）
