VS 2008 Navigate To Multiple Url Using For Loop?
May 21, 2010
Im new to VB.net I've tried search everywhere about this but I cant find the solution.So, basically I have, one button, one web browser, and one list box In the list box is the URL of website: [URL]..
So, what Im going to do is, once I click the button, the web browser will navigate to URL in the listbox one by one..When it finish loads to 1st URL it goes to next URL and stop at the last URL.
How do I do that? I use for loop but when I try to debug, It doesnt wait until it finish..

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 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()

What I need to do is login to each url and submit data.I'm using the webbrowser component.The for loop will only show me the last loaded url. so this works only with the last url from my list.Also one more problem after it logins the second part is not executed.I tryed and isBusy still didn't worked.
While wb.IsBusy
End While
Ok so I have this code in a for loop For i As Integer = 0 To Line.GetUpperBound(0)
LinkItem = Line(i)
Items = LinkItem.Split(";")
MessageBox.Show("Item 1: " & Items(0) & " Item 2: " & Items(1) & " Item 3: " & Items(2))[

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 have a form with two web browsers. I have webbrowser1 navigate to a parent url and webrowser2 navigate to child url.
The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.
Should I be looking at cookies or something else?

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?

How do you navigate to a url in a webbrowser and wait for a specific time period like say 30 sec before inputting data into fields in a form? I know how to use WebBrowser1.DocumentCompleted but I don't want to use wait for the complete website to download. There are websites that don't completely download so I don't want to hang up the program.I tried using Sleep(30000) but that halts the program, it doesn't load the browser for a specific time period.

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'm making a web browser, and when the enter key is pressed in the address box, after I navigate to the URl, when a new URL is typed in, and the enter key is pressed, all that happens is it highlights the text, I tried to refresh the control, but it did not work. How do I fix this problem?

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?

I have a piece of code that loops through the rows in a database and brings out information.
The code is attached to a button(search). To search for data, you enter a phone number, the loop goes through the data rows and bring out the information is it is there.
Everything works great accept I have added a second table to the database.
So do I add a whole new loop statement? Example lets say I had a new data row, how can I add that to this statement so that both tables are searched?
This is the code:
Dim strGetRecord As String = masTxtPhoneField.Text
For validData = 0 To storedtData.Rows.Count - 1
If strGetRecord = storedData.Rows(validData)("fldphone").ToString Then

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 think I'm going about this the wrong way, but would like to know if anyone has achieved this. All I'm doing is printing a simple character map to 255 labels, each label containing a char. Not an assignment, just having fun.
