I've written a Twitter OAUth library in C# that you can use--all you have to do is compile it as a DLL and reference it in your VB project, it should work just fine from VB (.NET is interoperable that way, no need to convert). You can download a binary package from http://code.google.com/p/twarp/downloads/list (OAuth.Twitter.zip), it contains the library + all the dependencies. Sample code on using the library, both asynchronously and synchronously (from C#, should be easily convertible to VB) is available in the http://code.google.com/p/twarp/source/browse/#svn/trunk/src/Libraries/OAuth.Twitter/Samples folder. The library requires .NET 3.0 and higher, and is also portable to Mono. :) Cheers, - -- Bojan Rajkovic <boj...@brandeis.edu> Biochemistry '10, Brandeis University PGP Signature Key ID: 0x8783D016 PGP Encryption Key ID: 0x2497B8B2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQIcBAEBAgAGBQJKQ+XpAAoJEO4IwQyHg9AWvVwP/iA8cd9ZgxWevon2tOXbMRsD Zi5942UUuH/8RVaT+OswBgTRFf764JzYzqA5Sj+tKGn8ESs0QyGoaFINSNIkOENj HSbI+g1MKQzv7fc5Woz6QBE9rELvSj/M+0E9j4FzX3kyevchEM2ImSgVWNxkINLv QuI5raoJwKIrgaYR5tel20XqhJAdBCt3MofwfoHKvUd1aOmUajlKiN0QNXEUxeON SZpwRXRryLgaDVIbqGsmWaii0Aj7lSdqCyYDZrA1+C6p+9x5a3s4JjFbQLgXm+c8 3IyZgTQBTJrRAPzGnm5/YizKNk2ycIlHI8tRmmUM2PMt8xPN6pNrOPtuNqpNZG4U OdIgjVkX74TbHQouxbxEJYfQm0ua3gWjlEoDHR+JeDRKg5D4xzt9iljx4/Jq0b8a pBIMYu+mXb/DhexIt4bjFPJCbqk/6s2ExGbWPiwwcFdXf3GF3WzGO1nx+Q4k1bDd 7fPhq2iLjJlAGcLx/yIgYTku4oqpYvWT8vwzEMlG35/pITuw6wSVZaqws9WnQghk FHP+4OOYjvmkyoTZXZhIQ2ZJXPrcFFRyf0xAJXtcRECQ1B+e/PMSQVZCzaI45NtX bztyAdGqfr9rFeFKOXkH8Gl9QXbGBbfBIdGOubx16iuWfPUoHk3rSwX2kE5Q/dPP A5d+rokbxzvQY6TZR4sf =8N+T -----END PGP SIGNATURE-----
