C++ Dynamic-link library problem

[lakehunt]

I use MFC C++ project.
I need to use IMSApiCLib.dll .
I try "imsapiGetLibraryVersion" function.
But it could not load success.
Please help me check.
thanks.


[Code]
---------- main.cpp ----------
#include <stdio.h>

extern "C" {
#include "IMSApiCLib.h"
}

int main() {

IMSAPIUTF8STRING version = NULL;
imsapiGetLibraryVersion(&version);

getchar();
return 0;
}


---------- IMSApiCLib.h ----------
#ifndef __IMSAPICLIB_H
#define __IMSAPICLIB_H

#ifdef __cplusplus
extern "C" {
#endif

#define IMSAPIVERSION "name=[IMSApiCLib] version=[8.00.00-1] buildtime=[2014-08-29 17:13:02]"

#undef WINDOWS
#undef LINUX

#include <wchar.h>

#ifndef __cdecl
#define __cdecl
#endif

.
..
...
....

/* definition of fix functions */
IMSAPILONG __cdecl imsapiInit(IMSAPIUTF8STRING anOptionsFilePath, IMSAPISTRING* jvmArguments);
IMSAPILONG __cdecl imsapiGetLibraryVersion(IMSAPIUTF8STRING* versionString);

#ifdef __cplusplus
}
#endif

#endif

I also use
--> HINSTANCE handler = LoadLibrary(L"IMSApiCLib.dll");

but it could not work.

You've specified the DLL to load at run time, but not what to link against at build time so the build fails.

try using #import <IMSApiCLib.dll>

I tend to put it in stdafx.h
