被例外困惑 [英] baffled by exception

问题描述

你好。

有人知道C＃调用COM

对象的方式和C ++调用COM对象的方式有什么区别吗？无论如何要使

后者模仿前者？


我有一个看似无法用C ++实例化的COM对象，但是可以

使用C＃和VB，这让我疯了 - 我不能弄清楚什么是错的

用它。

当任何C ++代码尝试实例化它时，它似乎抛出异常，引用用户断点作为原因

。

如果当它处于调试模式时，我点击''继续''异常，它重新抛出

它为：

System.Runtime.InteropServices.COMException（0xC0000096） ：例外来自

HRESULT：0xC0000096。


但是当try..catch为圆形时它仍然会抛出消息框！

这个COM对象，我完全拥有并且它的加密狗已插入。就像我说的那样，

我可以用其他语言实例化这个COM对象并且我可以实例化

使用这些的其他COM对象C ++中的方法。


他们可能不希望你从C ++中使用它，并且可以

告诉吗？

有什么想法吗？

干杯！

Hello.
Does anybody know if there is a difference between the way C# calls a COM
object, and the way C++ calls a COM object? And is there anyway to make the
latter emulate the former?

I have a COM object which seemingly can''t be instantiated using C++, but can
using C# and VB, and it''s driving me insane - I can''t work out what''s wrong
with it.
It just seems to throw an exception, citing ''User Breakpoint'' as the cause
of the exception when any C++ code tried to instantiate it.
If I click ''continue'' to the exception when it''s in debug mode, it rethrows
it as:
System.Runtime.InteropServices.COMException (0xC0000096): Exception from
HRESULT: 0xC0000096.

But it still throws up the message box when the try..catch is round it!
This COM object, I fully own and the dongle to it is plugged in. Like I say,
I can instantiate this COM object in other languages and I can instantiate
other COM objects using these methods in C++.

Is it possible they could have not wanted you to use it from C++, and can
tell?
Any ideas?
Cheers!

推荐答案

Bonj，


这个对我来说似乎不太可能，因为.NET中的机制最终使用与C ++相同的机制。你能说明你是如何在

..NET中做到的，以及你是如何用C ++做的？也许你没有正确设置

环境或公寓，这可能是你的
问题的根源。


希望这会有所帮助。

Bonj,

This seems highly unlikely to me, as the mechanism in .NET ultimately
uses the same mechanism that C++ uses. Can you show how you are doing it in
..NET and how you are doing it in C++? Perhaps you are not setting up the
environment or the apartment correctly, and this could be the source of your
problems.

Hope this helps.

如果未正确安装COM编组代码（代理/存根），则单元类型不匹配只会成为问题。此错误是与尝试使用的特权指令相关的COM错误。它通常与代理/存根dll（其中包含接口编组代码）相关，与COM对象实现的接口定义不一致。

An apartment type mismatch is only going to be a problem if the COM marshalling code (proxy/stub) is not installed properly. This error is a COM error relating to a privileged instruction attempting to be used. It is often in relation to the proxy/stub dll (that has the interface marshalling code in it) being out of step with the definition of the interface the COM object has implemented.
