here is my error message. it seems that my IIS has some problem.
some example which I last examined was working well. those were using
.config file in the current directory. But this one is a bit different.
I should make bin subdirectory. Why only my machine not working? it never
find bin subdirectly so that it wouldn't refer to istringencoder.dll.
Please help me.


Console.WriteLine("encoded : {0}", s2);
Console.WriteLine("decoded : {0}", objRef.Decode(s2));

Place web.config file (listing 5.16) in app root directory, not bin
