HTTPWebRequest Navigate Click Download
Mar 19, 2010
I used to use WebBrowser only and I want to learn how to use httpwebrequest so first of all is there a way to see how does httpwebrequest work like a window with gui just for the testing? I want to navigate to a website + keep cookies headers and everything make it user behavior like.
Page loaded? Click download
<div id="downloadButton"></div>
After you click a new page will loaded and in IE you will see the yellow bar (activex/information bar) and you have to click and allow this don't really sure how it works with httpwebrequest but firefox doesn't have that yellow bar anyway allow it and download the file run the file and that's it the install the user will do it manually.

I want to download a file using an HTTPWebRequest. I found sample code, but it seems a bit outdated. What i have:
Imports System.IO
Imports System.Net
Imports System.Text[code].....
It seems that WebRequestFactory doesn't exist. Is there a better way to do this? Or how can i fix it?

I'm trying to import data from our database into the Property Agent module for DotNetNuke. I can do every thing ok except for one issue.
Some units have their images stored as simple urls and those are no problem. The problem I'm having is some of our images are actually retrieved from an aspx page the outputs the image data and the browser displays that.[code]...

I am trying to navigate to a website with json data using the webbrowser controls but it keeps prompting me to download the file instead of properly navigating to the page as firefox would.I have tried doing a regular navigate:
frmBrowser.WebBrowser1.Navigate("http://us.wowarmory.com/auctionhouse/money.json")
As well as editing the header content type with many different types:
frmBrowser.WebBrowser1.Navigate("http://us.wowarmory.com/auctionhouse/money.json", "", Nothing, "Content-Type: text/plain" & vbCrLf)
But cant seem to get it working.. I need to use the webbrowser to navigate as you have to be logged in to access this file.
Edit: Also, manually editing my computers registry won't work as I need to distribute this program.
Edit2: Just wanted to add that this code would work if it were the same session, but since it webclient creates a new session it doesn't work
Dim oWeb As New System.Net.WebClient()
oWeb.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Dim bytArguments As Byte() = System.Text.Encoding.ASCII.GetBytes(params)[code].....

I am working on httpwebrequest method to read the page from start to the end, as I have got the same id of the html tag in the html page and I am not sure how to click on the links when select with the listview items by using with the boolean.
Here it is the
Imports System.Net
Imports System.IO
Imports System
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Address of URL
[Code] .....
How I could click the links by using the httpwebrequest method while I select the listview items and select the right links using with the boolean? I want to click the links when I select on the listview items as if the boolean is true:
PHP
<p id="delete"> <a href="delete.php?id=ANYNUMBER1">Delete</a></td><p id="delete"> <a href="delete.php?id=ANYNUMBER2">Delete</a></td>

How can I click the submit button after I've sent a string to a website using httpwebrequest?
Heres my code:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim wr As HttpWebRequest = DirectCast(WebRequest.Create("[URL]"), HttpWebRequest)
Dim encoder As New System.Text.ASCIIEncoding
Dim stringdata As String = "code=" & Clipboard.GetText & Environment.NewLine & "&submit=submit;"
[Code] .....
But it doesn't work. the string I'm sending converts ok when I open the site + do the conversion manually, but using the above code it reports an error:
Statement fragment: please enter a complete statement.
I've double checked + it must be a problem with the stringdata line.

I have a form with two web browsers. I have webbrowser1 navigate to a parent url and webrowser2 navigate to child url.
The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.
Should I be looking at cookies or something else?

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?

I'm creating a CD that when inserted into a CD-Rom will AutoRun, which brings up the program starting with a splash screen, then the first window form. All this works, no problem. On the first window form I have a button (one of many) all buttons work (so far) except this one button. (I actually haven't test3d the buttonjs to see if they work on / from a CD yet, but they work in Debug).
I would like to have the user click the button, and have that button be tied to a zip file or an exe file that is in a folder on my CD, that will be downloaded to the user's computer. I would like the usual window to come up asking the user where the user would like to save the file, the user will choose the folder, click the save button and the file downloads from the CD to the hard drive of the user's computer, so the user can open it later. It doesn't have to Run from the CD, it is just to download to be accessed later.
Some files will be a Zip and others are Exe files that I would like to have downloaded to the user's PC by way of a button click. Of course the user's computer will need to be able to know which drive the CD is in.
This is what I've tried and doesn't seem to work...Have not tried it from directly from CD (Haven't tried anything directly from the CD as of yet, but after this problem my next step is try and make a AutoRun CD and test the program).
Process.Start(Application.StartupPath &
"SoftwareApp1.zip")
I'll start another post for How to Make my Program ready for a CD. I think it may involve Publishing...but publishing only made a setup.exe, which is Not what I want.

I can't seem to figure this out. Below is some HTML on a webpage after I've logged in. The HTML is generated by javascript, and not sure how to do the same thing they do.On the site I simply click the "Georgia KMA" cell in the table that pops up, then click "OK" button at bottom.I've gotten the login done, now I'm stuck, can't get a "Click" to occur in the cell. I've got the javascript up and can't identify for sure what handling the click input.What I'm doing is writing vbscript to automate a file download.I don't have access to modify the site in any way.I have verified by using a msgbox that the DIV item 107 is the correct item for what I want. with this code it doesn't highlight the cell so when I click OK it doesn't do anything but tell me to select one of the listed items.
My Code so far:
'code to halt internet explorer
Sub WaitForLoad(obj)
Do While ie.Busy: Loop[code]......

Using the Visual basic browser I would simply, at least for the input of information.
If WebBrowser1.Document.GetElementById("Input") Is Nothing Then
Else
Dim txt As HtmlElement = WebBrowser1.Document.GetElementById("Input")[code]....
But in the case of WebClient class, How do I do this ?As I have been told this is so much faster.

I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder.I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction.Currently everything works, except the downloading of the file.I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from?

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:

I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
