不过，我是指在同一个DLL在同一个解决方案，Windows窗体应用程序，这是工作的罚款。对于这个Windows应用程序工作，我用的Dependency Walker软件来解决DLL的很少依赖。但我无法弄清楚如何，当我尝试运行Web服务解决此错误。我的操作系统是Windows 7旗舰版64位
However I refer the same dll for windows form application in the same solution and it is working fine. For this windows application to work I used Dependency Walker software to resolve few dependencies of the dll. But I can't figure out how to resolve this error when I try to run the web service. My operating system is Windows 7 Ultimate 64 bit
我可以知道为什么我米收到此错误，以及如何解决这个问题？
谢谢
Can I know why I m getting this error and how to resolve this ? thanks
推荐答案
我的猜测是你的C ++ DLL可能非托管code。
My guess is your C++ dll is likely unmanaged code.
+ DLL你闯民宅，它在32位或64编译的C？
The C++ dll you're refering, it's compiled in 32bit or 64?
- 的Windows应用程序的工作，因为你
启动过程。 - Web应用程序正在运行的内
Web服务器的应用程序池
它被设置为在32位运行
或64。
在IIS管理器中，选择应用程序
池。在应用列表
池，选择应用程序池您
配置为您的Web应用程序。在操作
窗格中，选择在高级设置
编辑应用程序池。展开
常规设置，设置启用32位
应用为True，然后单击确定。
In IIS Manager, select Application Pools. In the list of Application Pools, select the application pool you have configured for your web app. In the Actions pane, select Advanced Settings under Edit Application Pool. Expand the General settings, set Enable 32-bit Applications to True, and click OK.
