问题描述
我有一个非常简单的DLL写在非托管C ++，我从我的应用程序访问。我最近切换到Visual Studio 2010，该DLL从55k下降到35k，没有代码更改，现在它将不再加载在Windows 2000中。我没有更改任何代码或编译器设置。我有我的定义设置为 0x0500 ，应该包括Windows 2000支持。
I have a very simple DLL written in unmanaged C++ that I access from my application. I recently switch to Visual Studio 2010, and the DLL went from 55k down to 35k with no code changes, and now it will no longer load in Windows 2000. I didn't change any code or compiler settings. I have my defines setup for 0x0500, which should include Windows 2000 support. Has anyone else run into this, or have any ideas of what I can do?
推荐答案
。它实际上甚至比这更糟糕，。这是因为VS2010的C运行库需要EncodePointer API，直到SP2才可用。
Visual Studio 2010 cannot build binaries that run on Windows 2000. It's actually even worse than that, they won't run on Windows XP RTM or Windows XP Service Pack 1 either. This is because VS2010's C runtime library requires the EncodePointer API which is not available until SP2.
如果你想支持早期版本，的Windows。您可以将整个项目移动到Visual Studio 2008，也可以从Visual Studio 2010项目中定位vc90（Visual Studio 2008）工具集。有关后一种方法的更多详细信息，请参阅此anwser到我的相关问题。
It appears you're stuck building with installing VS2008 if you want to support earlier versions of Windows. You can either move your entire project to Visual Studio 2008 or you can target the vc90 (Visual Studio 2008) toolset from within your Visual Studio 2010 projects. For more details on the latter method, see this anwser to my related question here.
