错误LNK2020:未解析的令牌(0A000017)IID_IStorage和错误LNK2001:未解析的外部符号IID_IStorage [英] error LNK2020: unresolved token (0A000017) IID_IStorage and error LNK2001: unresolved external symbol IID_IStorage

问题描述

你好，
首先，我使用StgCreateDocfile()创建了一个存储文件，然后在其中添加了一些文件.然后我尝试使用
打开此存储文件

Hello,
First, I created a storage file using StgCreateDocfile() then added some files in it. Then i tried to open this storage file using

hr = StgOpenStorageEx(L"E:\\Storage.stg",STGM_READ|STGM_SHARE_DENY_WRITE,STGFMT_DOCFILE,0, NULL, 0,IID_IStorage,(void**)&pStorage);

当我执行win32控制台应用程序时，它的效果很好.

但是，当我尝试将其添加到Windows窗体应用程序项目中的相同代码，将c ++类添加到项目中，然后将我的代码添加到该类时，它会生成运行时错误

which worked fine when i did it win32 console application.

But when i tried it add the same code in Windows form application project, adding a c++ class to project and then my code to that class, it generate a runtime error

1>Recovery.obj : error LNK2020: unresolved token (0A000017) IID_IStorage
1>Recovery.obj : error LNK2001: unresolved external symbol IID_IStorage

新创建的类中的IID_IStorage有什么问题?

我需要在项目设置中对链接器属性做些事情吗?

whats the problem with IID_IStorage in newly created class.

Do i need to do something with Linker properties in project setting?

推荐答案

似乎您缺少一个lib文件.尝试将 Uuid.lib 添加到链接器库中.

It seems you are missing a lib file. Try adding Uuid.lib to your linker libraries.

我认为您可能需要在源代码中包含Objidl.h，如

I think you may need to include Objidl.h in your source code as described here[^] in MSDN.
