Just wondering what browser type the VB.NET reads as when it visits a webpage. For instance on my website it shows a break down of all the different browsers that accessed my site.
View 1 RepliesI am trying to change the UserAgent of the WebBrowser control in a Winforms application.
I have successfully achieved this by using the following code:
[DllImport("urlmon.dll", CharSet = CharSet.Ansi)]
private static extern int UrlMkSetSessionOption(
int dwOption, string pBuffer, int dwBufferLength, int dwReserved);
[Code]....
The only problem is that this only works once. When I try to run the ChangeUserAgent() method for the second time it doesn't work. I stays set to the first changed value. This is quite annoying and I've tried everything but it just won't change more than once.
how to change the useragent on webbrowser control?
View 10 RepliesOk.. I got the useragent to change:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code].....

vb
Private Function Download()
Dim htr As System.Net.HttpWebRequest = CType(System.Net.WebRequest.Create("http://www.google.es/"), System.Net.HttpWebRequest)
htr.UserAgent = "ExplorerExpres 3.0"
[code]....
i need send UserAgent then download the font code?
I use webbrowser as File Explorer.
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 created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox.

I'm Re-developing an old VB6 program that I wrote years ago.The program has a "feature" where is shells 6 applications 1 after another, the form hangs whilst it is processing all the commands.Is there a way in .net to "properly" queue a list of commands?I've seen numerous things about WaitForExit - but again this hangs the main form and would like to do it a bit more proper this time round.Can I use Backround Worker for this function or have I completely misunderstood?i can queue all my tasks in background worker and after each exit go onto the next app & report progress back into the main form.Is this the best way of doing this sort of thing?Is there any way to change how progress is reported.

View 7 RepliesIve tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?
View 6 RepliesThe code is very simple.
If File.Exists(strFileMovingTo) Then File.Delete(strFileMovingTo)
If File.Exists(strFileMovingTo) Then
Call SendEmail(Globals.EmailInternetTeam, "dev-sql@fad.co.uk", "Display Jpg
[Code]....
However a FileNotFoundException exception is thrown during File.Copy even though its wrapped in a If File.Exists ... End If to check its existance.
The great thing is if you run this through the debugger it nearly always works, when released as an app it almost never works.
I'm having a problem publishing an application written in VB.NET in VS2005 using ClickOnce.I get the error:
Code Snippet
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.

View 20 RepliesSo I've got a button that adds a tab using the tabcontrol object.
TabControl1.TabPages.Add("Test")

Each tab will have the same components, but might goto a different url.
I'm tried to make my own web browser by using WebBrowser control in VB.NET 2010. When I run my program it is work fine but when I try to open any link in new window it is opened in Internet Explorer. So how can I start new window in my web browser?
View 2 RepliesI 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?
View 1 RepliesNow, 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.
View 5 RepliesI'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).

Having:

it navigates only to the last website [URL] i think that's because the for loop is faster that navigation process?
I have got a web browser control in a windows form and i want it to have a width of 100%?
View 13 RepliesI'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?
