Hi
I'm trying to connect to twitter from our desktop application
The Stage 1 goes OK and I get the page with the PIN code but when I try and do stage 2 I keep getting 401 errors.
Here is the last log
Thanks

OK to ask this a slightly different way.
Is there anyone on here using Chilkat HTTP oAuth and is managing to successfully sign into twitter using 'any account' (by that I mean any account other than the account that created the twitter 'app')
If the answer is yes please can you post a code snippet as I just can't get past sending back the PIN stage
Thanks
PS yes I am following the example here http://www.example-code.com/vb/http_twitter_pin_authorization2.asp
OK I've got a bit further but am now really tearing my hair out on this one.
My initial mistake was to assume that the token/secret that came back in part one is important and I should set those properties but it turns out I shouldn't
I am now in the situation where the stage 1 and stage 2 work in the sense I get an OK and auth/secrect tokens from stage 2
However I can't use these to post a tweet on the timeline and get a 401 ewrror
I've tried many many combinations without success
The app ha "Read, Write and Direct Access" permissions
I've pasted my class below
I'm creating/destroying the http objects in desperation to ensure there is nothing 'left over' at each stage
I've found this about encoding https://dev.twitter.com/discussions/11280
and this about Expect: 100-continue https://dev.twitter.com/discussions/15408
I'm really struggling with this now and some help would be GREATLY appreciated

Note if I use the tokens in "Your access token" in my account twitter using the same statuses/up0date call I can post to my own timeline as me .... but obliviously that does not enable the application to post on other users timeline as themselves as it circumvents the PIN login process and they are my keys anyway
So the long and the short of it is I've been unsuccessful in using the keys obtained via the oAuth process to actually do anything with
Has anyone achieved this regardless of language ?
Thanks
Having successfully got the token from the two stage auth process it even fails it's own verify_credentials check ! ?
PLEASE can someone on here give me their own example (in any language) of a two stage auth and a successful action after that using the token to prove i'm doing something wrong in my own code
Here is my verify_credentials in a language called Dataflex and i'm getting a 401 error back just like all my other attempts to use the received tokens
Thanks

A polite but frustrated post.
With over 100 views is there really no one on here using Chilkat to obtain an oAuth login from Twitter and then actively doing something with it
I just can't get the received key to work
Thanks
With a significant amount of help from Chilkat themselves I've now got to the bottom of it
For anyone else reading this my problem was ....
In a nutshell at Stage 2 of the oAuth process requires the token and secret from stage 1 and the second request should be a GET not a POST as per the Chilkat examples
