System.Windows.Forms.WebBrowser.Navigate To Load A Network File?
Aug 30, 2011
We are using a web browser to show a pdf file located in a folder on the network. The code looks like this:
System.Windows.Forms.WebBrowser.Navigate(New Uri("\hostpath ofile.pdf"))
This works fine, but now I have to use a specific user to access this file and I don't know how to include the user name, password and domain in the URI. Is it posible to add user credentials to the URI? Can I use another variant of Navigate method to accomplish this?

VB2005. In my application I am required to go to a website, collect info, and then display both the webpage and the info collected. For this I am using the System.Windows.Forms.WebBrowser component and have it working faily well. The only thing now is that in order to get to external websites the company requires us to login to the firewall proxy server. For example when I visit [URL] a login box pops-up for our firewall server [URL] and I sign in with ID 9999 and password "pass". I am trying to programatically do this with the WebBrowser by using the credentails but have not found any relevant examples. Is this possible with the System.Windows.Forms.WebBrowser component?

If you are interested, I am doing this because I do not like having to drag and drop my browser etc. I just right click the URL in Chrome and select (Play on My TV) a customized dropdown item, at which point my Player finds the TV, opens the URL, maximizes itself and plays the content

I'm instantiating a WebBrowser object and programmatically clicking a button to navigate. Is there a way (property, method, or voodoo ritual) for me to check the browser after it lands on the new page to see 1) the form method that was used and 2) the post data?

I am venturing into WPF - first time in (VB).NET - and trying to re-create a project I started in MS Access VBA. It basically scrapes a series of pages within a web application. As you may have surmised I am having trouble with the LoadCompleted event.I have searched and found some information on it, but the "flow" of the code only lends itself to waiting for one page to load.url...All of the code execution is run in the DocumentLoaded event which works fine when you just need to navigate to one page and execute code. But I need to perform a series of these cycles for my application. How can I reliably wait for the document to fully load while still keeping the code execution in the same Sub AND not locking the UI thread? [code]That's it. Repeat for n times. my interactions with each DOM are significantly different.

Essentially what I want to do is copy a WebBrowser object such that I can do the equivalent of "Open In New Tab" or "Open In New Window" actions, maintaining any posted data. I don't just want to navigate to the same URL as in the original WebBrowser object, rather I want to repeat the HttpWebRequest.

I'm guessing there is a really simple answer to this but i've spent the best part of 2 days trying to get it to work and cannot figure it out.Basically, I want is the webbrowser to point to a local folder on a machine. A different one depending on who is logged on. The code I have so far is as follows.
Imports System.IO
Public Class frmFav
Private Sub frmFav_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim username As String
[code]....
I cannot get the URL value of the webbrowser (FavProgs) to take the value of directoryname. If I set the URL value in the properties for FavProgs it does what I want it to do perfectly.

So I have this code: [code] When I run it though, I get the following error:Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.TextBox'.If I remove a button, it moves on to give me the same error but for a label..

I want to make something that can on button click navigate to a page, wait the time I specified and navigate to another page..
[CODE...]
This does not do what I thought it would do..I think that the problem is that when it sees System.Threading.Thread.Sleep(5000) everything stops for 5 secs .How can I make it go to google.com and then after 5 seconds, yahoo?

Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.
at MusicManager2009.frmMain2.cmdLoadAlbum_Click(Object sender, EventArgs e)
at System.Windows.Forms.Control.OnClick(EventArgs e)
at System.Windows.Forms.Button.OnClick(EventArgs e)
[code].....
All functions of the app, except those that start from the buttonclick in question, work as before in the problem version.The problem persists after rebuilding the entire solution, after restarting VS, and after rebooting the PC.

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:
