Hi,

I am new to coding with macros. I have this code and I am trying to run this by dynamically loading a class from a DLL.
Code:
#pragma once
#ifndef DLLEXPORTS_H
#define DLLEXPORTS_H
#ifdef _LoadPCDigDlls_h_
#define _LoadPCDigDlls_h_
#define CALLBACK __stdcall
#define IFC_IMP_DLL  __declspec(dllimport)
#endif //_LoadPCDigDlls_h_

#define IFCAPI __stdcall
#define IFCCALL IFC_IMP_DLL IFCAPI

typedef enum {
	IFC_CAP_MBOARD,		// Image Capture motherboard, e.g., IC-PCI,PCVision
	IFC_MNG_MBOARD,		// Image Manager motherboard, e.g., IM-PCI
	IFC_CMC_MBOARD,		// Computational module motherboard, e.g., CMC-PCI
	IFC_AM_DBOARD,
	IFC_CM_DBOARD,
	IFC_DM_DBOARD,
	IFC_NUM_BOARD_KINDS
} IFC_BOARD_KIND;

#define IFC_ACTIVE_CAMERA_FLAG 0x8000
typedef unsigned char    * pBYTE;  
#define IFC_INFINITE_FRAMES -1
typedef void *HIFCGRAB;


class IFC_IMP_DLL CIobject
{
public:

// Object model (types, destruction, allocation)
	virtual ~CIobject();  // virtual destructors are necessary

#ifdef new
#define _IFC_SAVE_NEW_
#undef new
#endif
	void* IFCAPI operator new(size_t nSize);
	void* IFCAPI operator new(size_t nSize,void* p);
	void  IFCAPI operator delete(void* p);
#if _MSC_VER >= 1200
	void IFCAPI operator delete(void* p, void* pPlace);
#endif

	// for file name/line number tracking using DEBUG_NEW
	void* IFCAPI operator new(size_t nSize, LPCSTR lpszFileName, int nLine);

#if _MSC_VER >= 1200
	void IFCAPI operator delete(void* p, LPCSTR lpszFileName, int nLine);
#endif

#if defined(_IFC_SAVE_NEW_) && defined(_DEBUG) && defined(DEBUG_NEW)
#define new DEBUG_NEW
#endif
#ifdef _IFC_SAVE_NEW_
#undef _IFC_SAVE_NEW_
#endif


	// Disable the copy constructor and assignment by default so you will get
	//   compiler errors instead of unexpected behaviour if you pass objects
	//   by value or assign objects.
protected:
	CIobject();

	CIobject(const CIobject& objectSrc);              // no implementation
	void operator=(const CIobject& objectSrc);       // no implementation
};

class IFC_IMP_DLL CModule : public CIobject 
{
public:
		CModule();
	virtual ~CModule();
};

class IFC_IMP_DLL CParentMod : public CModule  
{
public:
	CParentMod();
	virtual ~CParentMod();
};


typedef CParentMod * PCParentMod;

typedef PCParentMod  (CALLBACK* LPIfxCreateParentModule)(IFC_BOARD_KIND modKind, DWORD modSubkind, DWORD seqnum, char *cfgFile=NULL, BOOL inspectOnly=FALSE);
typedef PCParentMod  (CALLBACK* LPIfxCreateCaptureModule)(char *modName,DWORD seqnum, char *cfgFile);
typedef void (IFC_IMP_DLL* LPProcessCameraFilesInDir)(const pSTRING szPath, BOOL bRecurse = FALSE);
typedef BOOL (IFC_IMP_DLL* LPEnableJitGrabMemLock)(void);
typedef CICamera (IFC_IMP_DLL* LPGetCam)(DWORD camPortNum=IFC_ACTIVE_CAMERA_FLAG);

extern int LoadPCDigDlls();
extern int FreePCDigDlls();

When I build the solution I am getting these errors
