DLL creation process in windows application with CEN XFS

[venkat swaminathan]

Thanks your tip help me to start some invetigation.All these days we were with LINUX. Migrating to windows seems little difficult for me. Where should :

extern "C"
{

}

</pre>

be added??

Because SPITesh.H, the code has the expected tag...

#ifdef __cplusplus
extern "C" {
#endif
SPITEST_API HRESULT WINAPI WFPCancelAsyncRequest(HSERVICE hService, REQUESTID RequestID);
SPITEST_API HRESULT WINAPI WFPClose(HSERVICE hService, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPDeregister(HSERVICE hService, DWORD dwEventClass, HWND hWndReg, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPExecute(HSERVICE hService, DWORD dwCommand, LPVOID lpCmdData, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPGetInfo(HSERVICE hService, DWORD dwCategory, LPVOID lpQueryDetails, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPLock(HSERVICE hService, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPOpen(HSERVICE hService, LPSTR lpszLogicalName, HAPP hApp, LPSTR lpszAppID, DWORD dwTraceLevel, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID, HPROVIDER hProvider, DWORD dwSPIVersionsRequired, LPWFSVERSION lpSPIVersion, DWORD dwSrvcVersionsRequired, LPWFSVERSION lpSrvcVersion);
SPITEST_API HRESULT WINAPI WFPRegister(HSERVICE hService, DWORD dwEventClass, HWND hWndReg, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPSetTraceLevel(HSERVICE hService, DWORD dwTraceLevel);
SPITEST_API HRESULT WINAPI WFPUnloadService();
SPITEST_API HRESULT WINAPI WFPUnlock(HSERVICE hService, HWND hWnd, REQUESTID ReqID);
#ifdef __cplusplus
};
#endif

What you show inside SPITesh.H is the correct placement. Is that your file or the original vendor's file? In Visual Studio, when you compile the code as C++, it should automatically define __cplusplus . If it doesn't, then it might be that your source file extension is ".c" when it should be ".cpp".

The difficult we do right away... ...the impossible takes slightly longer.

Yes, I sm trying to follow the same. but still it is doing no good. https://drive.google.com/file/d/0B60pejPe6yiSejRGQ3JnLUl4dzA/view[^] The link contains the project ref files i made sure all files are CPP and Extern C just for the headers. What else should i look ifor?? is there some settings that i should set in VS 2010 Express

[Richard Andrew x64]

Try placing the

#ifdef __cplusplus
extern "C" {
#endif
// Functions
#ifdef __cplusplus
};
#endif

in the CPP file also, surrounding the functions you want to export. I think that is the issue.

NO luck still.... :(

[venkat swaminathan]

If possible can you just try downloading the code and check with your MS VS version??

[Richard Andrew x64]

I'm sorry. Maybe someone else will have some better ideas. :sigh:

I did. It won't compile because of a number of undefined symbols in SpiTest.cpp.

XFSMANAGER INSTALLER: ftp://ftp.cencenelec.eu/CEN/WhatWeDo/Fields/ICT/eBusiness/WS/XFS/CWA15748/XFS310SDKInstall.zip

That is the libray link.

I'm sorry, I'm not going to install anything on my development machine. Take a look at this article: extern "C"[^]

No problem , I will try some option too...
