I would like to be able to resolve a shell link ("shortcut") to find out what it's target filename is. I have code that does this in C using the COM shell routines. I don't know how to write an equivelent routine in VB.NET - can someone help? Either .NET 1.1 or 2.0 (VS2005) is OK. Thanks.

This is the C code that I currently have to resolve shell links:

HRESULT ResolveIt(HWND hwnd, LPCSTR lpszLinkFile, LPSTR lpszPath)
{
    HRESULT hres;
    IShellLink* psl;
    char szGotPath[MAX_PATH];
    char szDescription[MAX_PATH];
    WIN32_FIND_DATA wfd;
 
    *lpszPath = 0; // assume failure
 
    // Get a pointer to the IShellLink interface.
    hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER,
                            IID_IShellLink, (LPVOID*)&psl);
    if (SUCCEEDED(hres))
    {
        IPersistFile* ppf;
 
        // Get a pointer to the IPersistFile interface.
        hres = psl->QueryInterface(IID_IPersistFile, (void**)&ppf);
         
        if (SUCCEEDED(hres))
        {
            WCHAR wsz[MAX_PATH];
 
            // Ensure that the string is Unicode.
            MultiByteToWideChar(CP_ACP, 0, lpszLinkFile, -1, wsz, MAX_PATH);
 
            // TODO: Check return value from MultiByteWideChar to ensure
                     success.
 
            // Load the shortcut.
            hres = ppf->Load(wsz, STGM_READ);
           
            if (SUCCEEDED(hres))
            {
                // Resolve the link.
                hres = psl->Resolve(hwnd, 0);

                if (SUCCEEDED(hres))
                {
                    // Get the path to the link target.
                    hres = psl->GetPath(szGotPath,
                                        MAX_PATH,
                                        (WIN32_FIND_DATA*)&wfd,
                                        SLGP_SHORTPATH);

                    if (SUCCEEDED(hres))
                    {
                        // Get the description of the target.
                        hres = psl->GetDescription(szDescription, MAX_PATH);

                        if (SUCCEEDED(hres))
                        {
                            hres = StringCbCopy(lpszPath, sizeof(lpszPath),
                                                szGotPath);
                            if (SUCCEEDED(hres))
                            {
                                // Handle success
                            }
                            else
                                // application-defined function
                                HandleErr(hres);
                        }
                    }
                }
            }

            // Release the pointer to the IPersistFile interface.
            ppf->Release();
        }

        // Release the pointer to the IShellLink interface.
        psl->Release();
    }
    return hres;
}

There are several ways to do this... but the easiest is to use the Windows Scripting Host (WSH) libraries.

'Add a reference to "Windows Script Host Object Model" (IWshRuntimeLibrary)

    Dim Shell As IWshRuntimeLibrary.IWshShell_Class
    Dim Shortcut As IWshRuntimeLibrary.IWshShortcut_Class

    Shortcut = Shell.CreateShortcut(file)
    debug.writeline("TargetPath = " & Shortcut.TargetPath)
    debug.writeline("WorkingDirectory = " & Shortcut.WorkingDirectory)
    debug.writeline("IconLocation = " & Shortcut.IconLocation)
