需要将VB6 ActiveX DLL转换为与经典ASP的IIS7 64位一起使用 [英] Need to convert VB6 ActiveX DLL to work with IIS7 64bit with Classic ASP

问题描述

我需要移动一个用VB6创建的大型32位ActiveX DLL，它在IIS7中运行良好，但新要求是内部函数需要是64位。由于VB6没有64位，有没有人知道要采取的路径？该组件使用ASPTypeLibrary和COM +来获取查询字符串，表单元素和最终响应，如果需要，可以更改。



谢谢

I need to move a large 32-bit ActiveX DLL created with VB6 that works fine in IIS7, but a new requirement is that the functions inside need to be 64-bit. Since VB6 does not do 64bit, does anyone know of a path to take? The component uses ASPTypeLibrary and COM+ for getting querystrings, forms elements, and eventually response, and this can be changed if needed.

Thanks

推荐答案

VB6？ 64位指令集支持？只是忘记它。



参见，例如： http://stackoverflow.com/questions/1167102/can-a-vb6-component-be-compiled-to-64-bit [ ^ ]。



当然，您可以在64位系统上使用它，只能使用WoW64支持的x86（32位）进程： http://en.wikipedia.org/wiki/WOW64 [ ^ ]。



一般来说，VB6 ...（叹气）...请看最近这个主题：我的问题是关于visual basic 6 [ ^ ] :-)。







我确信最可行的解决方案是迁移到例如VB.NET。

VB6? 64-bit instruction-set support? Just forget it.

See, for example: http://stackoverflow.com/questions/1167102/can-a-vb6-component-be-compiled-to-64-bit[^].

Of course, you can use it on 64-bit systems, bit only with x86 (32-bit) processes which are supported by WoW64: http://en.wikipedia.org/wiki/WOW64[^].

And, generally, VB6… (sigh)… please see this recent thread: my question is about visual basic 6[^] :-).



I'm sure the most viable solution would be to migrate to, for example, VB.NET.

（我对谢尔盖的帖子的评论作为答案）



您可以将.NET暴露给COM操作就像它们一样ActiveX对象，请参阅：



将.NET暴露给COM（注意最后的答案）

MSDN .NET COM操作

另一个好的教程


但请注意，从大型vb6库到.NET的过渡将非常痛苦，您将不得不重写其中的大部分内容。尽量不要进行1> 1转换，.NET有一些VB6中没有的功能可能会让你的生活变得更轻松。

(My comment to Sergey's post as an answer)

You can expose .NET to COM operations just like they were ActiveX objects, see:

Exposing .NET To COM (pay attention to the very last answer)
MSDN .NET COM Operations
Another good tutorial

But be aware, the transition from a "large vb6" library to .NET will be very painful, you will have to rewrite a lot of it. Try not to do a 1->1 conversion, .NET has some features that weren't available in VB6 that may make your life a lot easier.
