Getting Shortcuts (.lnk) – Target and Arguments

Environment: VC6.0 SP2

I saw Michael Taupitz’s idea of creating Links (shortcuts) and
I realized that there are many times when we stumble across
a link in command prompt mode and we have no idea what this .lnk
file points to.

Here’s a function I wrote which returns the Target and Arguments
of a .lnk file in a CString. Hope you find it helpful.

CString GetShortcutTarget(const CString LinkFileName)
{
	HRESULT hres;
	CString Link, Temp = LinkFileName;
	Temp.MakeLower();
	if (Temp.Find(“.lnk”)==-1)           //Check if the name ends with .lnk
		Link = LinkFileName + “.lnk”;   //if not, append it
	else
		Link = LinkFileName;
	CString Info;
	Info.Empty();
	IShellLink* psl;
	//Create the ShellLink object
	hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER,
				IID_IShellLink, (LPVOID*) &psl);
	if (SUCCEEDED(hres))
	{
		IPersistFile* ppf;
		//Bind the ShellLink object to the Persistent File
		hres = psl->QueryInterface( IID_IPersistFile, (LPVOID *) &ppf);
		if (SUCCEEDED(hres))
		{
			WORD wsz[MAX_PATH];
			//Get a UNICODE wide string wsz from the Link path
			MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, Link, -1, wsz, 					    MAX_PATH);
			//Read the link into the persistent file
			hres = ppf->Load(wsz, 0);
			if (SUCCEEDED(hres))
			{
				//Read the target information from the link object
				//UNC paths are supported (SLGP_UNCPRIORITY)
				psl->GetPath(Temp.GetBuffer(1024), 1024, NULL, 				             SLGP_UNCPRIORITY);
				Temp.ReleaseBuffer();
				Info = Temp;
				//Read the arguments from the link object
				psl->GetArguments(Temp.GetBuffer(1024), 1024);
				Temp.ReleaseBuffer();
				Info += ” ” + Temp;
			}
		}
	}
	psl->Release();
	//Return the Target and the Argument as a CString
	return Info;
}
