Waiting For WebBrowser To Fully Load Between Multiple Navigate Calls
May 1, 2012
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.

i'm trying to make the program wait while the webbrowser document frame loads. I'm using the code below, but all that happens is the page load pauses while the do loop happens (which obviously will be neverending as the search function searches for a line of html particularly present in the page i'm waiting for the webbrowser to load).

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:

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?

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 recently Ported this C# proxy across to VB.net but I am having the same problems I did in C#... It doesn't fully load a web page (and some don't even load).

Imports System.Text
Module Module1
Private attempts As Integer = 0

As you can see in the following picture it dosn't completely load VBforums.com: As you can see above the page just stops and in the source code you can tell the page didn't completely load.

I want to make a message box appear to show that the webpage has already loaded. I have used the code below:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
WebBrowser1.Navigate("[URL]")
If WebBrowser1.ReadyState = WebBrowserReadyState.Complete Then
MsgBox("yahoo is now fully loaded ")
End If
The message box is not showing at all . I have looked for "DocumentComplete" but can't get it working ..

I need to let my webbrowser finish loading before continuing. the problem is, i have the stuff that needs to be done in a do loop, so i can't use documentcompleted.
i currently have
Form2.wb.Navigate(url)
While Form2.wb.IsBusy = True
'do nothing
End While
to check if the webbrowser is loading, but it doesnt really work.

I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

I'm working on a webcrawler in VB.net, and using the System.Forms.WebBrowser object for handling navigation on sites that use javascript or form posts, but I'm having a problem. When I navigate backwards (WebBrowser.GoBack()) to a page that was loaded with a form post, the page has expired and I have to do a refresh to resend the request. When I call a refresh (WebBrowser.Refresh()), a dialog box pops up to confirm. Is there a way I can get around this modal dialog in code?

I'm using a webbrowser control to pull some information from a website. It works fine.I load the web page when the user clicks a button and then I pull the information from the site when the page completely loads. I have this bit of code in the DocumentComplete event.I am doing this for two different websites. So, my code as it is, looks something likes this:
vb.net
Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
WebBrowser1.Navigate("http://www.website.com")
End If[code].....
If I add a second Navigate to the same WebBrowser control, and then add another Document. GetElementById line, using different variables, it doesn't work.Its obvious that it loads both sites and then it finishes. So, it never has time to finish the first load and then pull the info into the text box.Is there a way to do this? To load the first site, pull the info, load the second site, then pull the info from there?

I made a quick Web browser that I only want to show one page when you press a button ( you have to enter a name into a textbox and it will then make the URL to show), but the page has some links on it, which I don't want people to click on.
1) Disable the hyperlinks
2) Disable left clicks in the browser
3) Make the browser somehow only visible and not actually interactive with a mouse
I tried something like
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.AllowNavigation = True
[code]....
Which I assumed would allow navigation once you clicked the button, but would then not allow it once you are done clicking it, but it just stays at false.

I am making a webbrowser, can somebody tell me how to prevent my browser from opening new IE windows. Because what happens is, there are some links that will open new windows and therefore IE comes in place because it is set as default windows browser which I really don't want because my browser looks really bad if it opens links in another webbrowser. I want it to be just a basic browser, it has only one window, and it should navigate within that window. This is because the browser is integrated in a bigger application only for some website applications that are related to this main application.

I have a program that has a webBrowser navigate through a few pages, and when it gets to the last page I set it to navigate to, checks if there is a certain string on that page. I just switched my code around to use multithreading and now the statement
If WebBrowser1.DocmentText.Contains("...") Then
...
End If
Generates an InvalidCastException that says "Specified Cast is Not Valid".
Here is how I start the thread (when a button is clicked)
FUBCThread.Start()
And here is the Sub that is run
Public Sub beginFUBC()
While True
If TimeOfDay > "11:31:00 PM" Or TimeOfDay < "07:00:00 AM" Then
