New version of tiny uploader available.

Been getting a lot of emails asking for the source code for the demo application TwitMee that uses my delphi twitter library, so finally uploaded it, you can get it here:

https://eden.fm/twitmee/

2.7:
– Added a 64 bit version. Context menu works with this one. (note: aero thumbnails capture doesn’t yet work in this version for x64)
– Cropped capture now displays a live view while you select the area.
– Added a “current session” log area, which is deleted after you restart.

v0.3:

– Added a method: RetrievePIN(user,pass), with this you can avoid the user having to login and return with an access PIN, the app will retrieve it on its own by simulating a login etc. Use with care, since this method is prone to errors whenever Twitter changes something in their login and auth process. Check usage.pas for details on when to use this.
Note: reposted with a small modification to fix an error in the preauth process, redownload if you got 0.3 before.

Slightly modified my delphi twitter library to work with the latest ICS distribution and to remove the dependency of an altered OverbyteIcsHttpProt file.

2013 fix/update: http://code.google.com/p/delphi-twitter-library/

Edit: As of December 2012 Twitter api is using GZip in every callback, so you’ll have to enable content encoding before every Get/Post call, and then load the result from a gzipped stream in the RequestDone procs.

Edit June 2012: This twitter library is now deprecated and will no longer be updated. I’ve rewritten it as a generic OAuth lib to use with both Twitter and Imgur (and any other OAuth 1.0 services) for a closed source project.

This is my take on Open Auth and Twitter for Delphi. I recently had to look into it to update a twitter plugin for my Mal Upater application, so I made this small library along with a test application TwitMee. There is barely nothing at all for Delphi, and the little
I found was overcomplicated and didn’t work with Unicode (f.e. japanese symbols etc) (my library does).

I’ve been asked by a few people to make it open source, so here’s the code, use it freely as long you comply with the GPL v3 license.

Requirements: one of the latest versions of Delphi which includes Unicode. (probably easy to adapt using Jedi’s jcl implementation
for unicode strings as well).
