在MFC C ++应用程序中实现extern WINAPI调用 [英] Implementing extern WINAPI call in MFC C++ App

问题描述

我正在使用 Windows Form App C ++ 。
我必须使用一些有

 的头文件HRESULT extern WINAPI StartUp（DWORD dwVRequired，LPVERSION lpVersion）; 
  

我必须在 Form1.h

  private：System :: Void Form1_Load（System :: Object ^ sender，System :: EventArgs ^ e）{
 APPVERSION version; 
 HRESULT result = APPStartUp（APP_VERSIONS，& version）; 
} 
  

但我得到这样的编译错误

错误1错误LNK2028：未解析的令牌（0A000025）externClong
__stdcall APPStartUp（unsigned long，struct _version *） @ $$ J18YGJKPAU_wfsversion @@@ Z）在函数
中引用private：void __clrcall MyAppPresenter :: Form1 :: Form1_Load（class

（？Form1_Load @ Form1 @ MyAppPresenter @@ $$ FA $ AAMXP $ AAVObject @ System @@ P $ AAVEventArgs @ 4 @@ Z）C：\Projects\MyAppPresenter\MyAppPresenter\MyAppPresenter.obj MyAppPresenter

我假设它与
有关将MSVS2010 C ++控制台代码移植到MSVS2010 C ++ GUI失败。为什么？

但是怎么做呢？
任何线索如何修复？

解决方案

我检查了控制台C ++项目，发现 .vsxproj 有

 < ItemGroup> 
< Library Include =C：\Program Files\Common Files\GCFApp\lib\msmanager.lib/> 
< / ItemGroup> 
  

所以我只是手动添加这个代码到Windows Form C ++项目文件，现在它工作。 p>

无论如何，我不知道如何使用VS 2010的GUI添加它。

I am working with Windows Form App C++. I have to use some header file that has

HRESULT extern WINAPI StartUp ( DWORD dwVRequired, LPVERSION lpVersion);

I have to execute this method within Form1.h

private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {
    APPVERSION version;
    HRESULT result = APPStartUp(APP_VERSIONS, &version);
}

But I am getting the compile error like this

Error 1 error LNK2028: unresolved token (0A000025) "extern "C" long __stdcall APPStartUp(unsigned long,struct _version *)" (?WFSStartUp@@$$J18YGJKPAU_wfsversion@@@Z) referenced in function "private: void __clrcall MyAppPresenter::Form1::Form1_Load(class System::Object ^,class System::EventArgs ^)" (?Form1_Load@Form1@MyAppPresenter@@$$FA$AAMXP$AAVObject@System@@P$AAVEventArgs@4@@Z) C:\Projects\MyAppPresenter\MyAppPresenter\MyAppPresenter.obj MyAppPresenter

I assume it has something to do with MSVS2010 C++ Console Code Ported to MSVS2010 C++ GUI is Failing. Why?

But how it can be done? Any clue how it could be fixed?

解决方案

I checked the console C++ project and found that *.vsxproj has

<ItemGroup>
    <Library Include="C:\Program Files\Common Files\GCFApp\lib\msmanager.lib" />
</ItemGroup>

So I just added this code to the Windows Form C++ project file manually and now it works.

Anyway I have no clue how to add it using GUI of VS 2010.
