I have a WebBrowser Control in my VB.NET application. Now the it browses through many URLs (may be 10 - 20) and I want that each of the page HTML saved in text file. Now the thing is that when I write the HTML of page in file, it does not write the HTML of current page rather than the initial one because it calls the event before even the page is loaded.
How can I wait until the page is completely loaded before calling any event?
I tried the following code but it doesn't works.
Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete
Application.DoEvents()
Loop
wait for the document to be loaded before moving to the next line?
I am trying to test the Forward and Backwards capabilities.. but if you do the following:
Dim i = New Form
i.wbHelp.Navigate(New System.Uri("test.htm"))
i.wbHelp.Navigate(New System.Uri("test2.htm"))
i.ClickBackwards()
It doesn't run the DocumentLoaded or the Navigated() event until it is to late. To run integrated tests I would need to either wait for the result.. Or does the URI even get loaded at all if the Control is not visible?
I need my webbrowser to go to the page and wait for it to load so the bot can continue for example:
WebBrowser1.Navigate("url")
'wait for page to load if it loads to the next coding
WebBrowser1.Document.GetElementById("Email").SetAttribute("value", (0))
how to get my program to submit user data into a login form and then wait until the next page is done loading so that it can examine the contents of the page and determine whether the login succeeded or failed. Here's my current code:
Public Class Dialog1
Private Sub Dialog1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 1 RepliesI am making this program that has a loop that goes to a website and fills in a form within the loop. But first, here is my code thus far
Dim message As String = TextBox3.Text
Dim loopnumber As Integer = TextBox4.Text 'makes the necessary variables
Dim browser As New WebBrowser
Dim url As String

But what happens is that the loop runs a few times then it errors on the setattribute line (line 19 above) with
NullRefrenceException was unhandled
And I have a feeling that it is not loading the page fully before it tries to fill in the form.

I would like to use the WebRquest Class in Visual Basic to get the Inner Text or Inner HTML of a specific element in the requested web page.For instance, if the webpage contains an element with the id ="label1" and has inner text ="hello" then I should use the WebRquest to extract the inner text of the specified element and not the source of the whole page. Note that I do know the alternative solution , which is using the Web Browser Control . But unfortunately this is unsuffiecent for my application.

While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net
