0xC0020001: The string binding is invalid. - Only occurring in WPF
提问by keynesiancross
First off, I should probably say that I'm probably at a grade 5 level with this stuff... I'm using a C++ add-in in a WPF application. Whenever I try to exit the program, I get this error:
首先，我可能应该说我对这些东西可能处于 5 年级水平...我在 WPF 应用程序中使用 C++ 加载项。每当我尝试退出程序时，都会收到此错误：
Unhandled exception at 0x770d15de in Raptor.exe: 0xC0020001: The string binding is invalid.
Raptor.exe 中 0x770d15de 处的未处理异常：0xC0020001：字符串绑定无效。
I've been using this blog entryto try and figure the problem out, but I'm having no luck. One thing I noticed though, when I use the same C++ addin in a Console application, calling many of the same methods used in the WPF application, the Console exits without a problem.
我一直在使用这个博客条目来尝试解决问题，但我没有运气。但是我注意到的一件事是，当我在控制台应用程序中使用相同的 C++ 插件时，调用 WPF 应用程序中使用的许多相同的方法时，控制台会毫无问题地退出。
I've also gone through the C++ code and cannot find a single static variable declared anywhere. There are static methods though.
我还浏览了 C++ 代码，但找不到在任何地方声明的单个静态变量。虽然有静态方法。
Any help would be much appreciated!
任何帮助将非常感激！
EDIT: I enabled a number of debugging features to see where this breaks. It was breaking the sp_counted_impl.hpp file (Boost) on the last bracket of the following:
编辑：我启用了许多调试功能来查看哪里出错了。它破坏了以下最后一个括号中的 sp_counted_impl.hpp 文件（Boost）：
virtual void dispose() // nothrow
{
#if defined(BOOST_SP_ENABLE_DEBUG_HOOKS)
boost::sp_scalar_destructor_hook( px_, sizeof(X), this );
#endif
boost::checked_delete( px_ );
}

This occurs with certain DLLs that don't link with native libraries and thus their DllMain does not initialize some needed native subsystem (like CRT or ATL). Sounds like you have a mixed-mode DLL of some sort. One recommended solution is to remove the entry point from the managed DLL: Remove the Entry Point of the Managed DLL
这种情况发生在某些不与本机库链接的 DLL 中，因此它们的 DllMain 不会初始化一些所需的本机子系统（如 CRT 或 ATL）。听起来您有某种混合模式的 DLL。一种推荐的解决方案是从托管 DLL 中删除入口点：删除托管 DLL 的入口点
- Link with /NOENTRY. In Solution Explorer, right-click the project node, click Properties. In the Property Pages dialog box, click Linker, click Command Line, and then add this switch to the Additional Options field.
- Link msvcrt.lib. In the Property Pages dialog box, click Linker, click Input., and then add msvcrt.lib to the Additional Dependencies property.
- Remove nochkclr.obj. On the Input page (same page as in the previous step), remove nochkclr.obj from the Additional Dependencies property.
- Link in the CRT. On the Input page (same page as in the previous step), add __DllMainCRTStartup@12 to the Force Symbol References property.
- 与 /NOENTRY 链接。在解决方案资源管理器中，右键单击项目节点，单击属性。在属性页对话框中，单击链接器，单击命令行，然后将此开关添加到附加选项字段。
- 链接 msvcrt.lib。在“属性页”对话框中，单击链接器，单击输入。，然后将 msvcrt.lib 添加到附加依赖项属性。
- 删除 nochkclr.obj。在 Input 页面（与上一步相同的页面）上，从 Additional Dependencies 属性中删除 nochkclr.obj。
- CRT 中的链接。在 Input 页面（与上一步相同的页面）上，将 __DllMainCRTStartup@12 添加到 Force Symbol References 属性。
