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.
View 10 RepliesIn my program I am trying to make a combobox that when the user hits enter it will navigate the web browser to the site address that the user entered into the combobox. I tried this code:
If Keys.Enter Then
WebBrowser1.Navigate(ComboBox1.Text)
And then when I debugged the program and tried it out, the web browser did nothing.
I am not sure if this is possiable but I am looking to build an application that will login to a web site, navigate the site and download files. I would like to do this all in code and able to run multiple instances of the program to get information from many different web sites. Is something like this possiable in VB.net?
View 3 RepliesI 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?

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?

View 10 RepliesI 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.

On another thread, someone said it cant be done with webbrowser control, but im new automation.
View 11 RepliesI'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.

View 1 RepliesI am using an embedded webbrowser control to access a third-party website, populate the username and password boxes on their front page, and login. The problem I have is that the resulting window that the site returns to me is in the form of a new window. What I want to do is capture this window and all it's session/cookie data in to the original webbrowser control, as even if I direct the original window to the same resulting url, some kind of authentication data is missing and the site tells me I have logged out, even though the popup window works fine. I need that page in the original control so that I can continue to access it programmatically, and I don't really want to get in to the complication of accessing the new window, as I expect I'll have to delve in to the api or something.

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 trying to use my web browser control to get retrieve date from a specific page, including all sub-page content. Problem is some of the sub-pages are on a separate domain and thus I am getting a permission deigned error when i try to access the frame [through document.windows.frames(i).document].Is there any work around to do this, even if I have to manually change security settings? I tried turning all my settings in IE to allow and still same error. I will only be running the app locally and no one will be browsing on IE so I can literally change anything needed to get this to work (even install older version of IE which may allow it but can still handle JS processing).
Note the reason I am using web browser is a great majority of data I will be accessing is JS generated, so I need to access the DOM after JS processed / generated the HTML. Because of this, simply using SOCKETS to get the HTML is really not an option. Even if I had the HTML, I still need some type of engine to process all of the DOM elements based off javascript.

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?

View 5 RepliesI 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.
