将非托管C ++代码从32位转换为64位

[英]Converting unmanaged C++ code from 32 bit to 64 bit

原文 2010-03-24 10:05:20 4 1 c++/ unmanaged/ 32bit-64bit

I have an unmanaged C++ 32 bit application that produces a dll. 我有一个产生dll的非托管C ++ 32位应用程序。 Now, I want to build it for 64 bit system. 现在，我想为64位系统构建它。 My development system is 32 bit. 我的开发系统是32位。 It uses oledb.lib activeds.lib adsiid.lib ws2_32.lib libraries to build the dll. 它使用oledb.lib activeds.lib adsiid.lib ws2_32.lib库来构建dll。 What I have done so far is : Changed the configuration settings and set the Active solution platform to x64. 到目前为止，我所做的是：更改了配置设置，并将Active Solution Platform设置为x64。 It built the application successfully. 它成功构建了应用程序。 But I could not register the dll on a 64 bit machine. 但是我无法在64位计算机上注册dll。 While I tried to do so, I got the following error: 当我尝试这样做时，出现以下错误：

Unable to load DLL C:\\Windows\\System32\\KBTicketExperience.dll 无法加载DLL C：\\ Windows \\ System32 \\ KBTicketExperience.dll

Process Name: dllhost.exe 进程名称：dllhost.exe

Comsvcs.dll file version: ENU 2001.12.8530.16385 shp during component registration. Comsvcs.dll文件版本：组件注册期间的ENU 2001.12.8530.16385 shp。 Unable to validate DLL entry points. 无法验证DLL入口点。

Would you please tell me how to get rid of this problem? 您能告诉我如何摆脱这个问题吗？ Thanks in advance. 提前致谢。

I recommend creating a new project/workspace to build this DLL that is 64-bit through and through--no 32-bit anything. 我建议创建一个新的项目/工作区来构建此DLL，该DLL始终是64位的，没有32位的东西。 Assuming the DLL that this project works, you can look more closely at the differences between the projects and got from there. 假定该项目可以工作的DLL，您可以更仔细地查看项目之间的区别，并从那里得到。
