The source code shows how to do everything available from the GUI. For example, search around on BIN_USBSNOOPY.

I see a function UnpackAndInstall, after looking the function, it seems using FindResource to get the resource, and this invoke me some other question.I saw another third-party usbsniffer recently, and its ui is written by c sharp, but when I compile its source code, it
can not load its sysfile, however the exe file the web it provided can work well.
the error come from the following codes:

Code: [Select]

private static bool ExtractDriverFiles(out string mydir)
        {
            string tempdir = Path.GetTempPath();
            // This needs to be the same dir for uninstall (dpinst not cool here)
            mydir = Path.Combine(tempdir, "xxx_temp");
            try
            {
                Directory.CreateDirectory(mydir);
                WriteDrverFile(sysFile, mydir);
                WriteDrverFile(infFile, mydir);
                WriteDrverFile(coinstFile, mydir);
                WriteDrverFile(dpinstFile, mydir);
            }
            catch
            {
                return false;
            }
            return true;
        }
        private static void WriteDrverFile(string resname, string dir)
        {
            Assembly ass = Assembly.GetExecutingAssembly();
            ResourceManager rm = new ResourceManager("xxx.driver", ass);

            ResourceSet set = rm.GetResourceSet(CultureInfo.CurrentCulture, true, true);
            byte[] buf = (byte[])set.GetObject(resname);

            Stream w = File.OpenWrite(Path.Combine(dir, resname));
            w.Write(buf, 0, buf.Length);
            w.Flush();
            w.Close();
        }


and the error comes from the following two caluse

Code: [Select]

            ResourceManager rm = new ResourceManager("xxx.driver", ass);

            ResourceSet set = rm.GetResourceSet(CultureInfo.CurrentCulture, true, true);

I still can not figure out the problem, and how to make sure the problem it is from and how to handle it,
thanks.

If it can't find the resource, check your path settings or specify the complete path.

I don't know exactly how the usb driver be installed and load driver, and how to make sure its resource
location. I try to trace SnoopyPro0.22, but in visual studio 2010, after transformation, it can not
be compiled directly. And I still can not make sure another third-party freeware usb sniffer driver
can work well, even its exe file can work.
If there any good method to make sure the problem, thanks a lot.

I don't know of any updated version. You may need to search on the error messages you're seeing to find out how get it working
