Visual Basic 2008 Web Browser Navigate Via Textbox With Multiple Lines - Web Browser Control - Vb 2008 Webbrowser Navigate
Sep 3, 2009
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 have a webbrowser1 control that navigates via Textbox1.text (W/multiplelines) and set on a Timer1 (every .25 seconds).My issue is that I need to navigate to at least 1200-1500 urls before Timer1.stop (), but my webbrowser1 seems to only make it to 200-500 max, before I get an error saying that my program is "Not Responding" and freezes.

I recently upgrade a project from vb 6 to 2008. Most of the code runs fine.I have a webbrowser form control that I use to navigate local files and display them with. (i have a file list box that you click which calls the navigate of the browser control). Most file types i have test work fine and display just as they would in a real browser window. Excel, PDFs, etc... so examples of files that utilize "plugins" like acrobat reader inside the browser work great. Tiff files are the exception. No error is thrown in vb, but the browser throws 2 runtime errors, included at the end here. After the browser errors are ignored the program continues execution but will just not display the file.
i can type the path to the file (eg c: estfielsfilename.tif) in a regular browser window and it displays just like it should, inside IE, using a plugin.Prior to upgrading, depending on what was installed on the computer, navigating to a tif would open the tif with picture and fax viewer, or display it with a tif viewer plugin.

when click NO to debug it goes to

Basically I have a webcrawler app which uses a web-browser control to navigate to a URL. Once the page is loaded, I use the function below to grab the HTML. Once I obtain the HTML, using HTML Agility Pack I extract the plaintext. Once this is down, with a click of a button I save the url, and plaintext to the database (using sql server).
tb_HTML.Text = WebBrowser1.document.Body.OuterHtml
Now my question is how can I carry the above as a background process, whereby say I have a form and enter all the url I need to extract the plain text from i.e. download the HTML and then using HAP extract the text and then automatically save the result inside the dB.

I can create them using Ctrl+T(webbrowser controls and all) but after that I don't have any idea on how to control them(let's say I select the 5 tab and I don't know how to make that web browser control to navigate to a given webpage). I was thinking of creating an array of webbrowsers but I don;t know how that works.

In my app I am using a web browser control, I am displaying a list of files that are there in selected Directory, when the file type is of some image I do it as WebBrowser1.Navigate(sFileName), the image is then displayed in the Web Browser Control, when there is Word Doc I had code that converts the word doc to HTML and it is displayed in the WB Control all good so far, now when the file is of type xls, xlsx I am not converting the file to HTML instead I just use the navigate command and open the file in Excel so that user can then edit it and save it on his system. Now the problem is lets say I am toggling through pages in Directory first file is Image so it will be displayed next when it is Excel file then it will open the file in MS Excel but the WebBrowser COntrol has that previously opened image, I want to clear that when the excel file is opened. So here is what I tried. [code]It navigates to Excel file but does not display text and the image from previous file persists in the web browser control.I even tried to navigate it to "about:blank" but it then does not navigate to Excel file.

I have built my own browser 9see attached code) however I would like to modify the code so that textbox1 reads a txt file at start and uses the contents of that text file to navigate to a URL of equal value to the text with in that text file. All this should happen at the launch of the web browser form. Example of the text file contents would be [URL] Code as follows:

I'm new to visual basic & have learned many new things in such a short period of time from being on the MSDN forums. I have learned particularly in the subject of automating web browsing control using the getattributes etc., but I have tried everything that I have seen in the forums to auto click the "Settings" link in a created gmail account and then have the browser automate the "Forwarding" to another gmail address. I haven't found a solution anywhere to accomplish this.
So here is an account to try out in which this should only take a few mins to a veteran coder:

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 have writtine a program in VB 2008 that uses "webrowser1.navigate" in a browser that I created on a form in my application, so that I could add buttons for other functions on that Form and to load a web page with Flash content. Everything seems to work fine on 32 bit machines but, on 64 bit machines when the web page is loaded, Falsh content does not work and I get a Security Warning asking "Do you want to install this software?" and the software is Adobe Flash Player. IE is 32 bit (on 64 bit machine) and has Flash Player installed and the Flash content works for this web page using IE.Is ther some code that I should add or a property that I should change on the VB 2008 Form containing the browser that I created, so that the Flash content will work?

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 simple program with a web browser control and a button that causes it to navigate to a certain web page, as well as an input and another button for entering a url directly.Everything was working fine until I started messing with the document completed event in the control.The form loads a url initially and after that 80% of the time it freezes when clicking the button or entering a new url. I deleted the document completed code and now it still freezes a majority of the time.

I have a problem to enter a web site by program and not manually. I just navigated WebBrowser1 to a web site. After the navigation there is a button in the site. The button will send me to a link if I will click on him. I got the link path (After calling to a Sub doing it) in a String call SitePath. Now after I got the button's path I tried to navigate the WebBrowser again to the new path. But, the WebBrowser navigates again to the same Web Page The Site do not let me to enter the link by program only manually when I click on the button. Is there a way to click on this button by program or other way to enter the path?

Is webbrowser.navigate method is synchronous or asynchronous?
example:
dim ct as integer =0
dim counter as integer =0
ct+=1
wbb.navigate(""http://www.yahoo.com")
counter+=1
will counter get increased after firing webbrowser.document completed event?

I have list of urls that I use a foreach loop on. I want to visit each url with the webbrowser and collect html, but the webbrowser only collects the html of the last url. I think the loop is too fast?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim Collecthtml As String = ""
Dim websitelist As List(Of String) = GetURLs()

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 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.

The web browser control that comes with visual basic 2008 is out-dated and is very slow to load a lot of newer web pages. How do I go about updating it?
Also, is it possible to use Google Chrome or Mozilla Firefox instead? Would I be able to use code like this in any of the newer browsers?:
