MS VS .Net a Class v Dll

[Lunatic]

Ako exportovat triedu z Dll? A ako ju potom pouzit v inom programe?

Som skusal uz vsetko mozne, ale pre moju neschopnost to stale nejde...

V sucastnosti mam nieco taketo:
Projekt TestClassDll
subor stdafx.h, na konci pridane riadky:

#define _TESTCLASS_DLLAPI_
#define _TESTCLASS_NOAUTOLIB_

subor TestClassDll.h, pridaval som prve dva odstavce (ale davam ho sem cely)

// TestClassDll.h : main header file for the TestClassDll DLL
//

#ifdef _TESTCLASS_DLLAPI_
	#define TESTCLASS_DLLAPI __declspec( dllexport )
#else
	#define TESTCLASS_DLLAPI __declspec( dllexport )
#endif

#ifndef _TESTCLASS_NOAUTOLIB_
#ifdef _DEBUG
#pragma comment(lib, "TestClassDlld.lib")
#else
#pragma comment(lib, "TestClassDll.lib")
#endif
#endif

#pragma once

#ifndef __AFXWIN_H__
	#error include 'stdafx.h' before including this file for PCH
#endif

#include "resource.h"		// main symbols


// CTestClassDllApp
// See TestClassDll.cpp for the implementation of this class
//

class CTestClassDllApp : public CWinApp
{
public:
	CTestClassDllApp();

// Overrides
public:
	virtual BOOL InitInstance();

	DECLARE_MESSAGE_MAP()
};

subor TestClass.h

#pragma once

#ifdef _TESTCLASS_DLLAPI_
	#define TESTCLASS_DLLAPI __declspec( dllexport )
#else
	#define TESTCLASS_DLLAPI __declspec( dllexport )
#endif
//#define MY_EXPORT __declspec( dllexport )

TESTCLASS_DLLAPI int MyFunc(int n);

int MyFunc(int n)
{
	return 6;
}

class TESTCLASS_DLLAPI TestClass
{
public:
	TestClass(void);
	~TestClass(void);
	CString GetName(void);
	CString name;
	void SetName(CString n);
};

subor TestClass.cpp

#include "StdAfx.h"
#include "testclass.h"

TestClass::TestClass(void)
: name(_T(""))
{
	name = "TestClass";
}

TestClass::~TestClass(void)
{
}

CString TestClass::GetName(void)
{
	return CString(name);
}

void TestClass::SetName(CString n)
{
	name = n;
}

Projekt TestUsingClassDll
subor stdafx.h bez zmeny
subor TestUsingClassDll.cpp

// TestUsingClassDll.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

#define MY_IMPORT __declspec( dllimport )

MY_IMPORT int MyFunc(int n);

int _tmain(int argc, _TCHAR* argv[])
{
	MY_IMPORT class TestClass {} *TstClss;
//	TstClss = new TestClass(); // komentar 1
//	TstClss.SetName("nazov"); // komentar 2
	printf("%d", MyFunc(17));
	getchar();
	return MyFunc(17);
}

Pokial zrusim komentovanie komentara 1 (posledny zdrojovy subor) vznikne mi chyba pri linkovani:

TestUsingClassDll error LNK2001: unresolved external symbol "__declspec(dllimport) class TestClass * TstClss" (__imp_?TstClss@@3PAVTestClass@@A)
TestUsingClassDll fatal error LNK1120: 1 unresolved externals

Pokial zrusim * pred TstClss (takze to uz nebude smernik), a zrusim komentovanie komentara 2, vznikne nasledujuca chyba:

c:\Documents and Settings\matej.W2003SVR04\My Documents\Visual Studio Projects\TestUsingClassDll\TestUsingClassDll.cpp(15): error C2039: 'SetName' : is not a member of '(int,_TCHAR *[])main::TestClass'

Najvacsia sranda je, ze pokial obidva komentare necham, skompiluje sa to i zlinkuje, a bez problemov to vypise "6", na co pouzije funkciu z tej Dll.

Ak viete co s tym, prosim poradte. Trapim sa s tym uz vyse tyzden a stale neviem z Dll exportovat triedu a pouzit tu triedu v programe ktory by pouzival tu Dll.

Som si predchvilkou vsimol chybu. Ale ani jej oprava nic nevyriesila.

#ifdef _TESTCLASS_DLLAPI_
	#define TESTCLASS_DLLAPI __declspec( dllexport )
#else
	#define TESTCLASS_DLLAPI __declspec( dllimport )
#endif
