I am trying to create an application that will login our company's intranet portal via a webpage. The webpage has a single frame in it that loads a secure(https) login form. After logging in, the application will need to read and send xml to and from the portal. I have been digging around and have seen a few different ways of submitting the login information from the program to the site, however, I have not gotten any of them to work. From what I can tell it is difficult to change the values of input boxes that are inside a frame. Am I accurate on this? There will be a large amount of data transfer between the app and the portal so I will need something lightweight but I have enough room that I would rather not reinvent the http/web-browser wheel if at all possible. The reason I say that is because I have read that some objects that handle web pages are very resource hungry. I have no preference on the .net frameworks as this is the area of VB thats kinda confusing. What I am looking for is either a point or violent shove in the right direction.
View 2 Repliesall I want is a function like this:
[URL] but then with the option to provide username & password. I have managed to do this with the webbrowser, first logging in then go to webpage and get source code but this takes much longer than just getting the source code...
Is there any way to do this? I found this:
[URL]
I tried with &username=...&password=... in the URL but it didn't work

I'm trying to use HttpwebRequest and Httpwebresponse to log into a website via POST then once authenticated have it redirect to a default page within the new site. I'm able to do a responsereader.ReadttoEnd() put am unsure of how to get an automatic redirect.
Dim ccContainer As New CookieContainer()
Dim encoding As New ASCIIEncoding()
Dim strId As String = "username"
[code]...
I think there is a problem with cookiecontainer (httpwebrequest)there are 2 main functions in my class, first getting a new form (a hidden token in form tag), and it should set the cookies (which not set) and then second function (doLogin) should login the form. why cookie is not set...?

Dim cookieCont As CookieContainer = New CookieContainer

My knowledge of VB.Net is quite limited and I'm trying to jump in at the deep end, I'm trying to log in to a website (a game in which I play) that requires a username and password, they must be submitted used the POST method and then I need to be able to view the source of the page to obtain further useful data.
This is what I have at the moment and it isn't working for me.
Function postRequest()
Dim s As String = ""
Dim username As String = txtUserName.Text

The last part and my application is complete. I am kind of familiar with HttpWebRequest, but not in terms of logging into this website. I've tried multiple things, I can't seem to find the right post methods from the HTML I think? Anyways, heres what I got.
[Code]...
1) How do I use cookies obtained from login to do subsequent requests? e.g. Login to a forum, then use the cookie obtained from login to access User CP and change settings.
2) How do I parse HTML via HttpWebRequest? Does mshtml work with HttpWebRequest? If so, how do I work with it? I thought of downloading the source code of the page I'm requesting into a richtextbox and do my stuff from there, but it sounds kinda impractical to me since I have to use regex to get the innertext of stuff (or not?).

View 6 RepliesI have browsed through many posts on this and have tried some of the suggestions but still not understanding it fully. I would like to scrape html pages that have some script running that usually executes the script to display a link after clicking. Some mentioned firebug and others talked about reverse engineering the code I need. But after trying reverse engineering I still dont see how to get the data after tracing the script function.[code]I am using vb.net and some sites were easy using firebug where looking at the script I was able to pull the data that I needed. What woudl I do in this scenario? the link is url... and the categories are what I am trying to access. Notice the url does not change.
