创建：

void CreateShortcut(LPCTSTR lpszExe, LPCTSTR lpszLnk)
{
	::CoInitialize(NULL);

	IShellLink *psl = NULL;
	IPersistFile *ppf = NULL;

	HRESULT hr = ::CoCreateInstance(
		CLSID_ShellLink,
		NULL,
		CLSCTX_INPROC_SERVER,
		IID_IShellLink,
		(LPVOID*)&psl);

	if (!SUCCEEDED(hr))
	{

	}

	psl->SetPath(lpszExe);
	//psl->SetArguments();

	TCHAR szWorkPath[MAX_PATH] = {0};

解析：

void  GetLinkPath(CString szLink,  CString& szPath) 
{ 
	CoInitialize(NULL); 
	szPath = _T("");

	IShellLink* psl = NULL;   
	TCHAR szGotPath[MAX_PATH] = {0}; 
	WIN32_FIND_DATA wfd = {0}; 

	HRESULT hr = ::CoCreateInstance(
		CLSID_ShellLink,
		NULL,
		CLSCTX_INPROC_SERVER,
		IID_IShellLink,
		(LPVOID*)&psl);

	if (!SUCCEEDED(hr))
	{
		return;
	}

	IPersistFile*  ppf = NULL; 
	hr =  psl->QueryInterface(IID_IPersistFile, (void**)&ppf); 
	if (!SUCCEEDED(hr))
	{
		return;
	}

	hr = ppf->Load(szLink.GetBuffer(), STGM_READ); 
	szLink.ReleaseBuffer();
	if (!SUCCEEDED(hr))
	{
		return;
	}

	hr = psl->Resolve(0, 0); 
	if (!SUCCEEDED(hr))
	{
		return;
	}
			
	hr = psl-> GetPath(szGotPath, 
						MAX_PATH,  
						(WIN32_FIND_DATA*)&wfd, 
						SLGP_SHORTPATH); 
	if (SUCCEEDED(hr))
	{
		szPath = szGotPath;
	}
			
	ppf->Release(); 
	psl->Release(); 
	CoUninitialize(); 
} 

调用：

	CreateShortcut(
		_T("C:\\WINDOWS\\system32\\notepad.exe"),  
		_T("C:\\Documents and Settings\\guoyou.huang\\桌面\\hgy的记事本.lnk")
		);

	CString szPath;
	GetLinkPath(_T("C:\\Documents and Settings\\guoyou.huang\\桌面\\我的记事本.lnk"),
		szPath);
