[twitter-dev] Re: How-To: Load the Twitter XML into a VB.Net XML Document...
Did I state otherwise? You are not reading my words - you are being blinded by the noise from your own head. What I stated is this; I authenticate my VB.NET web browser via PIN etc THIS means my browser is authenticated. If I try to access a page via the program with a TCP Client - I have to re-authenticate via PIN. This WAS a problem - my solution is to continue to use the web browser for authentication and extract the XML pages into an XML Document. Hence the above code. If you state otherwise - that you CAN use a TCP Client after already authenticating your VB.Net web browser - you are wrong. I imagine you think I am wrong - and that I am an idiot. Believe me - I am very skilled at programming. And this is my experience. The library is faulty. It does not process leading zero pins. The OAuth implementation is stupid - because it does not authenticate an program but a TCP method. Hence, you guys are s off the mark here it hurts me to talk to you. Really, srsly, it's pathetic that you DO NOT LISTEN. On Jul 1, 4:58 am, DWRoelands wrote: > You can absolutely authenticate in a web page, even if your > application is not a web application.

[twitter-dev] Re: How-To: Load the Twitter XML into a VB.Net XML Document...
Right - I am not scraping the PIN? I am using the web browser in .NET (which is similar to Internet Explorer) to authenticate via a pin and username / password credentials. The only part of the workflow I do not follow is opening the URL in IE - I open in it VB.NET Web Browser. But - my user has to input it to send it back - I do not retreive it. What I am retreiving is the XML document that is sent to the web browser. I am not sure if any of you have actually seen the pages yet - but I have a few problems with your Library. When the pin starts with a zero - the authentication fails. Are you converting the pin string to an integer in your library? This is the only reason why a leading zero would be stripped you see. That is my first problem with the library - it has not been tested in a real world example otherwise this would have been flagged long ago. Now - I am not sure why you would think I was scraping the PIN - my user inputs it into a VB textbox for sending back to the correct URL. This way - my web browser gets authenticated. Also, did you know a Login prompt appears from the browser window - asking the user for Login credentials a SECOND time!? This is most peculiar. Have anyone else experienced this or are basically just not experienced in writing for the Twitter API and just read the information pages. I am a programmer - writing a VB.NET application that is registered with Twitter. I require real world examples because my program is real world - not from the pages of the Twitter API documentation. So, lets make this clear divide here - I want to talk to programmers - not just people who THINK they know what is happening from the API man pages. lol
[twitter-dev] Re: How-To: Load the Twitter XML into a VB.Net XML Document...
What do you mean by screen scraping? Is it because I am taking the
HTML page and turning it into a XML document?
This is because of OAuth. It uses HTML pages to validate. Perhaps I am
wrong - but once I use a web browser to validate - I cannot use a TCP
Client to get the XML because I authenticated via a web browser. When
I tried to (for example) send the pin back via a HTTP Web Request it
failed. I am not sure if I am using the OAuth library Interface Class
I have for VB.NET correctly!?
But, the way I am doing it - I just keep a web browser open to make
the requests - and use the above code to filter off the XML.
I hope I am not breaking any rules? If Bojan R. wants to help me out
(he wrote the OAuth library I am using) then I'd much appreciate to do
it the *right* way.

Dim w As New System.IO.StreamWriter(fs)

This is a better example of code that does what the above code sample
should be doing rather than changing UTF8 to ASCII - I replace a '- <'
with a '<' remove any '&'s and trim the white space. This makes it
sorted for VB.Net whilst preserving most the document text.
[twitter-dev] Re: How-To: Load the Twitter XML into a VB.Net XML Document...
OMG! What a mistake! VB.NET does not support UTF8 encoding - BUT - that is because I was removing the - from UTF-8! Haha. What a silly mistake on my part! When I fixed it - UTF-8 works just fine in Visual Basic .Net! My code was at fault. But, the rest still stands - you have to remove the white space from the beginning of the document AND Remove the - from the rest of the document apart from UTF-8! Haha. Sorted it now.

This is a code snippet I took from my test program. It uses OAuth to
authenticate. But this snippet is not about OAuth! These are the
things you are required to do before you can issue an XML.DOC.LOAD()
call.
So, you have dimmed xml as a new system.xml.document
Now, you want to call xml.load(WebBrowser1.DocumentText)
Forget it!
You are required to format the Twitter XML Web Page BEFORE loading it
into an XML Document in VB.NET.
Firstly, there is white space at the beginning of the document that
needs removing.
Secondly, you have to replace every - and & otherwise it will fail to
load! (Definitely the & not so much the - )
Thirdly, you are required to reformat the document from UTF8 to ASCII.
The XML.Load() call in VB.NET DOES NOT SUPPORT UTF8 ENCODING! I
cannot stress this enough :)
No, I am not shouting - I am using caps as a replacement for italics!
Haha.
So, after all this, the document C:\temp.txt can be used to load in
your XML.load("C:\temp.txt") document. But, there are other issues -
such as deleting the file before updating (re-writing the new document
with updates) then re-loading the new file into the XML parser in
VB.NET. These are all issues I hope you can solve yourself. This post
is specific to formatting the Twitter XML to adhere to VB.NET
standards.

[twitter-dev] Re: PIN Authentication Examples?
Hi, Well, my experience of using a web browser in VB.Net is that you have to keep to the same browser and cannot mix a HTTPWebRequest with a WebBrowser1 object! What I tried was getting the pin number via a web browser object, then sending that back via a HTTPWebRequest class. It failed miserably. Perhaps it was my code? I too am writing a VB.NET program for Twitter! It is very exciting work. I would have finished it last week but I had a whole week off coding because of the flu. What I have left to do is parse all the XML into my program correctly. Also, just a quick note - the XML.document.load in VB.NET does NOT accept UTF-8 as an encoding method - so I suggest reformatting the XML document as ASCII before trying to load it. ALSO - remove any white space (there are about three spaces at the beginning of the document!) otherwise VB.NET throws its toys out the pram. There are a few other issues too with XML documents and Twitter - such as the '&' character being illegal. You have to replace every & with a non-space if you want your document to load! Other than that - I finally got my document into a VB.NET XML Document and now parsing the XML is easy-peasy. This is because all you have to do is specify which node name you want to retrieve - and VB.NEt does all the work! Haha. I am really tired today - but I might work on the VB.NET program some more later on after I finish my nap :)
[twitter-dev] Re: How-To: Get a Twitter Token via VB.NET
Thanks. I really needed to know the license because I am using a
creative-commons license for my Open Source program.
Your library really is the bomb! At first, I thought you had to input
the pin on EVERY request made by the program - but that is not true
thankfully :)
Also, I will give you full credit in the credits of the program - and
in the README supplied with it.
Would you like me to link to any website of yours?
Oh, and the program is coming along at a fair pace. The first version
for release should be completed within seven days!
The only thing stopping me coding right now is that I have the flu :(
Thanks again for such an excellent implementation of OAuth.

[twitter-dev] Re: How-To: Get a Twitter Token via VB.NET
Hi,
Yes, I copied the sample exactly - but I did not see the part where I
had to copy the URL to a browser to get the pin.
But, I have used your library to much success! It is amazing! I can
now login to twitter using OAuth!
Can you please tell me the following;
1. What license have you used for your code? (BSD, GPL ???)
2. Do you require crediting in any way if I were to use your code in
my application for release?
3. I am writing an Open Source application - can I use your code in it
without having to pay royalties?
Please answer these questions - as my application relies heavily on
your OAuth.Twitter.DLL

[twitter-dev] How-To: Get a Twitter Token via VB.NET
Hi, I have been working on an program that will eventually access the Twitter site. But, I have found the very first stage of OAuth very cumbersome. Basically, I have the following code; Dim url As String = "http://twitter.com/oauth/request_token"; Dim xml As String = "" Dim OAuth As New OAuth_Twitter Dim O As New OAuth.OAuthBase Dim consumerKey As String = "CgZiTeNqGk2c0eZSdb9qg" Dim consumerSecret As String = "Sf7DGMTiK4cyU8qOuqOWX4yCNCwAdcRAlAj02cOA" Dim token As String = "" Dim tokenSecret As String = "" Dim Method As String = "GET" Dim outURL As String = "http://twitter.com/statuses/show/ 123.xml" Dim querystring = "" Dim URI As New Uri(url) Dim nonce As String = O.GenerateNonce() Dim timeStamp As String = O.GenerateTimeStamp() REM//Generate Signature Dim sig As String = O.GenerateSignature(URI, _ consumerKey, _ consumerSecret, _ token, _ tokenSecret, _ Method, _ timeStamp, _ nonce, _ "", _ querystring) querystring &= "&oauth_signature=" & HttpUtility.UrlEncode (sig) Dim test As String = url & "?" & querystring Dim UR As System.Net.WebRequest = System.Net.WebRequest.Create (test) Dim str As System.IO.Stream = UR.GetResponse ().GetResponseStream() - The program fails at the end - where str is dimmed as a IO.Stream and a GetResponseStream() is attempted. I get a 401: Unauthorised message - and the program terminates. I think I am doing some thing wrong here, but I do not know what? Do I have to use GenerateSignature() from the OAuth class twice? How about using GenerateBaseSignature()? I am really confuzzled. Ha! Does anyone here know anything about VB.NET and OAuth implementations in this language?

Public Function AuthorizationLinkGet()
Dim ret As String = Nothing
Dim response As String = OAuthWebRequest("GET", REQUEST_TOKEN,
String.Empty)
If (response.Length > 0) Then
REM response contains token and token secret. We only
need the token.
Dim qs As NameValueCollection =
HttpUtility.ParseQueryString(response)
If (Not qs.Item("oauth_token") = Nothing) Then
ret = AUTHORISE & "?oauth_token=" & qs.Item
("oauth_token")
End If
End If
Return ret
End Function
---
This is the OAuthLinkGet function. It fails with an 401 :
Unauthorised!
This also calls the above offending function 'WebResponseGet' - as
part of 'OAuthWebRequest'.
As soon as WebResponseGet try to access the WebResponse - it gets a
401 Unauthorised.
So, it seems I need to to something with this part of the class.
Thanks - I really feel confident now that we have sussed out the
problems?
[twitter-dev] Re: Desperate for Help! Twitter API Blues...
Hi Matt, There is an OAuthLinkGet routine in the OAuth_Twitter Class. I am not sure if it is being used tho? That said, the code in Form1 basically implements Twitter OAuth Class - which in turn uses OAuth Class. It is a heirarchy of classes :) It should, really, be doing it properly because I only adopted the classes to VB.NET and did not write them from scratch myself. AND I am useing the official C# Base Class for OAuth - so it really should work :( But, I definitely think that is the problem - the nonces are not being updated between requests. But, when I update the nonces in the browser - I get a empty page? Is that normal? Perhaps some one here can help with the VB.Net side of things?
[twitter-dev] Re: Desperate for Help! Twitter API Blues...
Public Function WebResponseGet(ByVal web_Request As HttpWebRequest) Dim responseReader As StreamReader = Nothing Dim responseData As String = "" Try responseReader = New StreamReader (web_Request.GetResponse.GetResponseStream()) responseData = responseReader.ReadToEnd() Catch Throw Finally web_Request.GetResponse().GetResponseStream().Close() responseReader.Close() responseReader = Nothing End Try Return responseData End Function - This above is the final code for my VB.NET program. I think because it is retreiving the same URL twice or even three times - the nonce expires. Any one got any solutions to this problem?
[twitter-dev] Re: Desperate for Help! Twitter API Blues...
Well, Hi again Matt. Basically, it is hard to describe exactly what my app is doing because it is using third party code. Firstly, this is the URL I am trying to access; url = "http://twitter.com/statuses/show/123.xml"; Then, here are the URL's for authentication that my API uses; Public Const REQUEST_TOKEN As String = "http://twitter.com/oauth/ request_token" Public Const AUTHORISE As String = "http://twitter.com/oauth/ authorize" Public Const ACCESS_TOKEN As String = "http://twitter.com/oauth/ access_token" I am using the C# Base Class with a VB.NET adapted C# Class to interface with the C# Base Class for OAuth. That is basically everything! It generates a URL too. BUT - I just tried something: I added http://:@twitter.com/etc... To the URL that asks for the Login Prompt and also changed the Nonce. I get a blank page then! Haha. You see - when I clicked CANCEL on the Login prompt - I would get the following output; /oauth/access_token? oauth_version=1.0&oauth_nonce=9995405&oauth_timestamp=1245956104&oauth_signature_method=HMAC- SHA1&oauth_consumer_key=CgZiTeNqGk2c0eZSdb9qg&oauth_signature=DaoiZKL5EMak1RyvTsGzYhlKe7Y %3d Invalid / used nonce You see - the Nonces have been used for some reason? I changed the nonce from the original 6545405 to 9995405 and when I updated with a new nonce I got the blank page. When I tried to access the source code for you - I got the Login prompt again with the expired nonce. SO It seems the problem lies somewhere with updateing the nonces for each request? AND/OR Supplying Login Credentials? Perhaps this is what the 401 : Unauthorised error message from Visual Studio means during a Web Request? I will keep tinkering with the code by firstly adding my Twitter Username and Password to the URL as above - but also try updateing the nonce? Any ideas on how to do this? I have posted my code in the initial post.

[twitter-dev] Re: Desperate for Help! Twitter API Blues...
I have read that document. Like I said in my initial post - I have read the tutorials and FAQs. Furthermore - I have converted a C# Class that utilises OAuth C# Base Class to VB.NET without a hitch. It works just fine - the only problem is that it is reaching a Login prompt that is asking for credentials that I do not have. A. Williams - did you even read my last post? I find it highly ignorant of you to refer me to the guide when I have successfully authenticated the OAuth procedure. That said, will anyone who cares to read my posts reply with some thing that is relevant and makes sense? I have given all the URL's needed - the parameters I am passing to Twitters oauth page - and I am getting a LOGIN PROMPT. Read my previous posts for more information.

[twitter-dev] Re: Desperate for Help! Twitter API Blues...
WOW! Thanks! I'll try that! Just a side note - I extracted the URL and ran it thru a web browser - then it started popping open a Username / Password box? It stated; The server twitter.com at Twitter API requires a username and password. What is all this about? I ask, because, my twitter username and password do not work? When I ran the URL via the web browser object in VB.NET the document completed without any body of text. It just exited without a login prompt. Nothing. So, it seems the URL I am creating seems sound - as it created a Login prompt in google Chrome. But, I dunno what credentials I require for the login prompt? http://twitter.com/oauth/access_token?oauth_version=1.0&oauth_nonce=2475068&oauth_timestamp=1245949941&oauth_signature_method=HMAC-SHA1&oauth_consumer_key=CgZiTeNqGk2c0eZSdb9qg&oauth_signature=6Uq%2brP1nCHcS3WFLkPMtANO1Zso%3d This is the URL I used to access the login prompt.

Hi Matt, I'm coding in Visual Studio 2005. I am using a HTTP REQUEST function to make the request to the server. This is basically all I get to go on is the error messages. I dunno how to incorporate Charles into VB.NET? Also, how do I go about printing out the body from VB.NET? If any one else other than Matt would like to take a look at my code it really would help.

The remote server returned an error: (401) Unauthorized. This is the exact error. I was not being hostile - just going out my wits end! *smiles* I've de-stressed by laying in bed for the past hour trying to forget about the Twitter API and OAuth. Ha! That said - shall I include the URL I am using with Parameters? Perhaps that will help, no? I'll get right on that.
[twitter-dev] Desperate for Help! Twitter API Blues...
Apologies for the double post. I was using the wrong google account before. http://www.aponetworks.com/dumpurge/index.html Take a look at the source code here. PLEASE! I keep getting an 401 unauthorised when I try to access anything on twitter. Please help - I've followed all the tutorials - this really should be working and it is not... Is there a time delay between when you reecive your application tokens / secret to when they become active? Kind regards, Obrzut
