Webbrowser Proxy Using Headers?
Nov 16, 2005
What im trying to do is to use a proxy for the connections of my webbrowser controls i have in my program.I found this code on another forum that does almost what im looking for:Well,step 1 is to form the string you need to send. Use this function, and the format user:password for strSource.
Private Function Base64_Encode(strSource) As String
Const BASE64_TABLE As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
Dim strTempLine As String
[code].....

I am using a webbrowser control and loading a website that uses basic authentication. I pass the username and password in the additional header of the navigate routine. The problem is that the header is not retained while navigating the site.
I.E.I log into the site and pass the user name and password in the http header. When I click a link to access another page the header is removed and the site asks for credentials. If I was to just type the site into IE and log in the first time the headers are carried forward on all pages. how I can have the page retain the headers so the user never has to authenticate?
Dim sHeaders As String
Dim HelpBrowser As New WebBrowser
sHeaders = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("UserName:Password")) & Chr(13) & Chr(10)
Me.HelpBrowser.Navigate("http://www.mysite.com", True, Nothing, sHeaders)

Is it possible to set a WebBrowser control to use a proxy connection without changing all the other browsers also changing to that proxy?To clarify, I have an application that is monitoring a website but refreshing often enough during the day that I'm getting "you've made too many requests, please try again later". I'd like to get around that by using a proxy. Unfortunately not all anonymous proxies can be trusted for secure information like credit card information, so I only want to proxy the webbrowser control and not proxy any other non-application browsers.There is a site that explains quite well how to change the proxy (link not included, not certain on whether link posting allowed) but it changes the global settings on all browsers.I've tried to use 3rd party components (ex IPWorks HTTP control) however that doesn't work well with script-heavy sites that load and update dynamically - it only gets the empty skeleton of the page before being populated from the server DB.

I have strProxy and I want to load myurl.com and get the source code.
I've heard HttpWebRequest is the way to go for speed, since I will be loading many different webpages with proxies.
What is the simplest way to load the webpage with a proxy so I can then scrape the source?

I have a code that will change the proxy IP settings in the Registry. This works perfectly, however the second time I try to change it, the web browser does not use it - it uses the first one I changed to. For example..I start up the program. I enter 0.0.0.0 as the IP, and it changes to 0.0.0.0, which has been confirmed. A few minutes later, I enter 1.1.1.1 as the IP, but it still uses 0.0.0.0.

Is there a way to make your webbrowser connect (or your computer ping) to a website via proxy server? (ex: 123.123.123.123 :: 12345)
Not a proxy like corpask, but an IP and port.

I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.
Header 1
Item 1_1
Item 1_2
[code]....
I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.
1_1 1_2 1_3 2_1 2_2 2_3
