HttpWebRequest, WebBrowser, And Cookies (VB2010)?
Aug 26, 2011I'm writing a program for my sister for a game which she plays online. It uses a WebBrowser control, and HttpWebRequest as well.The basic function is it searches through the website, we'll say the url is http://hersite.com/pet/* (don't follow the link lol it's just an example) where * is a number and this is how it searches.I use a for loop to cycle the numbers from a specified start to end, and use an httpwebrequest to fetch the html code, then process the string using InStr and .split()When I access the webpage using the WebRequest.Navigate, it takes me to the page correctly. However, if I fetch the source through the HttpWebRequest, it fetches the source of the login page, which the website redircts you to if you are not logged in.Is there a way to transfer the cookies from the WebBrowser to my HttpWebRequest?
Some examples:Get the HTML somewhere in here I need to add the cookie to the http requester, don't I?
Function GetHTML(ByVal strPage As String) As String
Dim strReply As String = "NULL"
Try
Dim objHttpRequest As System.Net.HttpWebRequest

HttpWebRequest - Using Cookies Obtained From Login To Do Subsequent Requests
Nov 27, 20101) 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?).

VS 2008 - Clear IE Cookies Without Restart Program?
Jan 19, 2011I use this to delete cookies
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2")
works fine I checked the folder myself it deletes all .txt files.
But here Is the problem lets say I log into hotmail, Clicked the button to Clear my cookies. And navigate to log in page again, It will navigate me straight to inbox just as if I have cookies but the folder doesn't have .txt cookies file. just (index.dat). Is this means we must restart the program to this to take effect? (Works if you restart it) If so, how can I turn off webbrowser1 for a sec and turn it back? or something like that just to make sure it takes effect without me reopening the program.

Jan 14, 2011I am trying to have a DateTime variable which is in a MM/dd/yyyy HH:mm:ss format convert to dd/MM/yyyy HH:mm:ss. I am using VS2008 Pro, and when I create a var:
dim dt as datatime = datetime.now It automatticlly defaults to MM/dd/yyyyy. No matter if I convert, parse, use globalisation or anything... convert to a string, which works with dd/MM/yyyy, but the minute i move it to a DateTime var type it goes back to MM/dd/yyyy I need to use this date/time to insert into a MS SQL Database and the colume is datatime type. But also is part of the app.I do not want this to be a string, I can do that, but I do need it to be a datatime in the correct format (dd/MM/yyyy HH:mm:ss)

Jun 3, 2009I'm having an issue trying to pull information from a specific website. I've asked about this once before, but had no luck through searches or responses.In a nut shell, the issue I'm having is trying to pull information from several URLs from a site.When I load the first URL and pull the information, it works just fine. But if I want to pull another from that same site, it acts like it is loading, but doesn't pull the information. In order for me to gather that information, I have to restart the program, but that beats the purpose.So, I wanted to see if the issue was related to cookies or something else the webbrowser control creates when loading a site. If this is the case, I'd like to clear out this information, or at least try it, after each time it pulls the information from the site.
