Webbrowser Control To Automatically Navigate Through Facebook
Jun 26, 2011
I am using webbrowser control to automatically navigate through facebook.Nothing malicious, just an experiment of sorts.Im working on a bot that that would extract the names of all friends on my friends page, open up those pages, extract their friends names, and repeat.The end result would be a chart of who knows who. A sort of 'six degrees of separation' experiment.I have everything automated up until getting to my friends page and I am having trouble extracting the urls from my friends page. [code] Now, I figure I can extract from <div class=fsl fwb fcb">, but Im confused as to how to go about doing this. On another thread, someone said it cant be done with webbrowser control, but im new automation.
I have kept a webbrowser and 2 text boxes and one button when my application start it opens facebook page in browser and then i put the id and password in textboxes and then clik on the button then i got loged in but i want that if i looged in it will logout in every 10 sec. can anyone help in this topic
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 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?
in my form load, I have the web browser control navigate to a site. What I'm trying to do is when a user clicks button1, i want the program to look through the webpage and check if there is an image source equal to a static URL that I assign. this is basically just navigating to a website & checking if a certain link exists.
I'm using a webbrowser control in my program and I navigate to a page that uses sessions. I need to delete them somehow and I tried to close IE and enter it again and it worked, the sessions were deleted. But I've done it manually, and I need to do it through my program, so is there a way to imitate the closing and reopening of my webbrowser control?

I'm using a WebBrowser control in my current program in a bit of a bastardized way: I don't use it visually, I just use it because I'm more familiar with its events.
So, basically, I create a WebBrowser control and navigate to a page to login. Then, when logged in, I create a new WebBrowser control and navigate to a different page.
I've used this program for four months with no difficulty. Starting today, though, the second phase of that has been going really, really slowly. What used to take 3-5 seconds is taking 25-30 seconds. It still works eventually, it just takes a while.
Usually I would assume this was a server problem. However, navigating to the exact same URL in Firefox happens extremely quickly. Weirder still, within the program there is a user WebBrowser control -- I can copy/paste the URL the previous (not visible) WebBrowser was navigating toward into this user WebBrowser, and it goes just fine.
What in the world could be holding up this other "custom" WebBrowser? I don't even know where to begin in diagnosing this.It might be important to note that the site this is working based off recently underwent some changes -- but I can't imagine why that would affect only these "custom" WebBrowsers and not the user one in the same program.
I use the webbrowser control to navigate to certain websites and login and retrieve some data. For that I created a sub for each website. On the form i have a button that calls every sub when clicked. The problem is that I don't know how to pause or stop the process once started. If I quit the program it will still run in the background until all calls complete. I tried to use a thread, but that doesn't go well with the webbrowser control.
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 am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen. WebBrowser1.Document.Body.ScrollTop = 100 WebBrowser1.Document.Body.ScrollLeft = 200
I have placed the above commands in a command button and wait until the page has loaded before I press it and also in the WebBrowser1_DocumentCompleted sub
Other commands such as WebBrowser1.Document.Body.ScrollIntoView(True) Seem to work ok.
I need to automatically fill forms in a WebBrowser Control. There are TextBoxes and CheckBoxes. How can I automatically set their value programatically? Language: VB 2008?
I have it to where it automatically logs into facebook but the problem is I want for when I click on login It will logout the other account and log that one in and if it helps I have 2 textboxes that have email and password and one login button.
I'm using this control in a application to load the URL of a .jpg image. The thing is that the image is bigger than the control, so I want it to automatically resize the image, as IE does when the same thing happens there, and it even shows a little magnifier glass to restore the image to full size.How can this be achieved? What happens at default is that the image is bigger than the control, so a quarter of it shows and I have to scroll to see the rest.
I wanna send my credentials to facebook.com and to automatically press the 'login button' and I've tried this:
webbrowser1.navigate(http://www.facebook.com/) webbrowser1.document.GetElementById("email").SetAttribute("value", "my email") webbrowser1.document.GetElementById("pass").setAttribute("value", "My password") webbrowser1.document.GetElementById("I cannot find the ID for the login key..please help").invokemember("click")
Im want my webbrowser to remember the username and password on page that user log in at.Like FF where a bar appears and the user can chose to remember or not.I don't really
I have a facebook iframe app I'm trying to test using a WebBrowser Control on a form in VB.NET 2010. Whenever I try to access the WebBrowser.Document.Window.Frames frame object on a document where my app is showing in the broswer, I get an Access Denined exception. Reading around on the web, I see people saying that this is to keep scripts in a document from accessing content in iframes that are pulling content from another domain, as per [URL] for security reasons.
While I totally understand why this is done for the general public, how can I disable it on my machine so that I can run these tests? I can't properly test my app without doing it in the facebook iframe and using the WebBrowser control is the only way I know to do this test programmatically. I'm on windows server 2003 and ie8, .net4.0, if that helps. I own the domain where the app is, and its in AS.NET MVC2, so if there's anything I can do to the web code to enable this??? I also removed the Internet Explorer ENhanced Security COnfiguaration component, but that didn't help.

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 need to send a pdf file to a web page in VB.net. I found that there is a webbrowser control and I should be able to use the navigate() method to do it.However, there is no sample for doing so.
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 [Code] .....
I am developing a webbrowser and i have got a big problem..The webbrowser uses tabcontrol as a brwser to navigate.I have a problem , that the tabcontrol doesn't have the same events as webbrowser, so i can for example put my download manager in the FileDownload event becouse it isn't there, or a new window and all that evets usefull that webbrowser has and the tabcontrol doesn't.
I based a lot of my project on your Codebank submission for navigating web pages. I have ran into the problem a few times where it would stop navigating. You had recommended deleting the Interop files and rebuilding the solution. I have done this and it used to work just great afterwards (I was deleting all Interops and AxInterops in the Bin/Debug and Obj folders)I now have a strange case where it compiles and builds and navigates as expected on the computer I coded it on, but when I install it on another machine, it fails to navigate again. I made certain it worked directly before building and that I used the correct setup file but nothing I seem to do now cna make it navigate on the second machine. What else should I check?
