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;
}
