/*
CLnkFile lnk(filename); // calls IShellLink::Resolve()
if (lnk.isValidLink)
{
    if (user wants to open target)
        filename = strTarget;
}

or this:

CLnkFile lnk(filename); // doesn't call IShellLink::Resolve()
if (lnk.isValidLink)
{
    if (wxFile::Exists(lnk.strTarget))
    {
        if (user wants to open target)
            filename = strTarget;
    }
    else
    {
        if (user wants to resolve target)
        {
            wxString tmpName = lnk.Resolve(hwnd);
            if (user wants to open new target)
                filename = tmpName;
        }
    }
}

The question is whether you can call Resolve() to see whether the file exists
as originally intended, without searching other files or directories.
