.NET Webbrowser Control With Additional Headers?
Dec 16, 2009
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)

Here is my code:
Dim TestHeader As String = "Referer: [URL]"
If chkRefferer.Checked = True Then
WebBrowser1.Navigate(cmbUrl.Text, False, Nothing, TestHeader)
Else
WebBrowser1.Navigate(cmbUrl.Text)
End If
Whenever I try and browse to a page with the 'TestHeader', IE opens up and goes to the page.... However, if I navigate to the same page without the additional header, it loads up fine in my webbrowser control.

How can I change the headers (User-Agent, etc) for my webbrowser control, not just for the first page that I browse too, but for all pages.

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+/"

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

I have a listview control that I have a multitude of files displayed, in addition there are 6 columns in the listview that shows information about the file in question.
I have gotten this far, but my question is this: how do I allow the user to sort the listview by clicking on the column headers. Like one can do in list view in a Windows window?

If you click folder it opens new folder contents in WB window but if you click html document it opens in EXTERNAL viewer.
How do you get html document to open in WB while exploring ?

I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

I have a webbrowser control, where I show images (bmp files, that the program creates), and I want to add some UserControls to setup the images (as showing layers, or choosing colors to display). Is easy to do appropiate UserControls on VB.NET, and I know almost nothing about HTML, so, I would like to add standard VB.NET UserControls near the images.

So I've got a button that adds a tab using the tabcontrol object.
TabControl1.TabPages.Add("Test")
How would I add a webbrowser to that since i dont know what the tab page # of it will be specifically?
Each tab will have the same components, but might goto a different url.

I am writing a VB.Net WPF application that needs to display HTML content and websites. I am doing this using the webBrowser control. The application takes a significant performance hit running under x86 and I would really like to keep it set to Any-CPU. However the webBrowser controls need to be 32bit so they can run flash. So is there any way of achieving this? Running the 32-bit webBrowser in a 64bit process, or some alternative control that will manage this and allow me to load HTML from a string and a URL?

Now, for this particular project, I have to use the Webbrowser control in VB. I normally wouldn't, But I need to display some modified HTML. So here is my problem.
Dim htmlorig As String
Status.Text = "Loading: " & TextBox1.Text
web.Navigate(TextBox1.Text)
[Code]....
The Msgbox comes up as soon as you click the button and is empty, No page source.

I'm having an issue loading one of our work websites in a WebBrowser control. In IE, it works fine, but in the wb control, it does not seem to process correctly.There is a frame, "mainframe" which when you click "result", goes back to the "to do list". However, i get a blank page in the frame, and then when i hit refresh, it comes up with a scripted error "Page Already Sent" which i'm not sure what it is triggered by.The pages are JSP pages, and i don't know if that might have some effect, but i'm more confused as to why they would work perfectly in IE, and then not work in WebBrowser control.

I'm running a webbrowser control with a custom user agent.when I try to load google with it, there are a number of 'script errors' in the website, which I've hidden by setting 'Scripterrorssupressed' to true. Now however there is still an 'object error' which pops up when i try to load google.Every other website that I've tried loads fine, and when I click 'ok' google runs fine. I'm quite sure its something to do with google 'location services' trying to locate my browser, because it thinks its a cellphone (due to the custom user agent).

I have this code in VB.NET :
Having:
1 TextBox
1 Button
with this code:
Code:
Public Class Form1
Dim m As String()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
m = TextBox1.Text.Split(Environment.NewLine)
[code]....
it navigates only to the last website [URL] i think that's because the for loop is faster that navigation process?

I've downloaded and installed the control from here, but I can't get it to work! I've added the component so it appears in my toolbox, but when i try to draw it on a form it isn't visible. It size can't be changed from 0,0 or anything! I can't see a 'URL' section in its properties either, why is that?

Is it possible to autosize a webbrowser control? I mean I want it to be just big enough to show whatever HTML content I load into it (without scrolling), and no talller.
Or, alternatively, how do I find the height of a given HTML document? Once I do that, setting the height of the Web Browser is easy.
