IShellLinkを使用すれば出来ます。
CoInitialize(NULL);
HRESULT HR;
IShellLink *psl;
IPersistFile *ppf;
WideChar wsz[MAX_PATH];
char szGotPath[MAX_PATH];
WIN32_FIND_DATA wfd;
HR = CoCreateInstance(CLSID_ShellLink, NULL,
CLSCTX_INPROC_SERVER, IID_IShellLink, (void **)&psl);
if(SUCCEEDED(HR)){
HR = psl->QueryInterface(IID_IPersistFile, (void **)&ppf);
if(SUCCEEDED(HR)){
MultiByteToWideChar(CP_ACP, 0, "ショートカット.lnk", -1,
wsz, MAX_PATH );
HR = ppf->Load( wsz, STGM_READ );
if(SUCCEEDED(HR)){
HR = psl->Resolve(Application->Handle, SLR_ANY_MATCH);
if(SUCCEEDED(HR)){
HR = psl->GetPath(szGotPath, MAX_PATH,
(WIN32_FIND_DATA *)&wfd, SLGP_SHORTPATH );
Edit2->Text = szGotPath;
}
}
}
ppf->Release();
}
psl->Release();
}
CoUninitialize();
