关于调试 VB 组件的建议？

我对 VB 代码没有任何经验。但我确实知道我的 VB 应用程序有问题，该应用程序挂在他的 ocx 中。我可以在windbg中看到它一遍又一遍地抛出c000008f异常，我知道这只是VB异常处理，它与“浮点不精确结果”硬件异常无关（这只是微软的“辉煌” ' 的实现方式）。

那么，问题来了。我如何找出问题的真正所在？我这里没有安装 Visual Studio，但我的笔记本电脑上安装了 VS 2010 Express。不过，我认为这也行不通，我需要专业版来调试此类内容。

另外，我启用了问题应用程序的日志记录，这些是我得到的最后几行：

....

它只是重复DrawLayer 无穷无尽。使应用程序崩溃的功能成功，您可以看到检索到的数据几秒钟，然后它停止更新客户区并变成白色，鼠标指针仍然是沙漏，应用程序没有响应，在强制它之后关闭它在报告详细信息中说：“hungapp”

那么，有人知道如何找出它是如何失败的吗？我真的需要 Visual Studio Pro ftw 吗？（哦）'

原文

I don't have any experience with VB code. But I do know I have a problem with a VB app which hangs in a ocx of his. I can see in windbg that it throws the c000008f exception over and over again and i know that it's just the VB exception handling and it has nothing to do with the "Floating Point In-exact Result" hardware exception (it was just Microsoft's 'brilliant' way of implementing it).

So, the problem. How do I find out what the problem really is ? I don't have Visual Studio installed here, but I do have on my laptop VS 2010 Express installed. Still, I don't think that will work either, i need the Pro version to debug this kind of stuff.

Also, I enabled logging in the problem app and these are the last lines I get:

....

And it's just repeating DrawLayer ad infinitum. The function which crashes the app succeeds, you can catch a glimpse of the retrieved data for a few secs, then it stops updating the client area and turns to white, mouse pointer is still a hourglass, the app is nonresponsive, after forcing it to close it says in the report details: "hungapp"

So, anyone has a clue of how to find out how it fails ? Do I really need Visual Studio Pro ftw ? (o.o)'
