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 webbrowser on my windows form and a text box above that with a go button. The webrowser is a search page.Is what I would like to do is type something in the textbox and hit GO and it will search for that word in the webbrowser.The search is setup to where if you were to set the url as it would bring up the results for "keyword"Is there a way with the navigate function to do something like.[URL]..basically I need a way to append the text from the textbox at the end of the url.
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 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?
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 need to make an asynchronous call to a method which for the sake of simplicity counts from 1 to 100. If an exception is thrown during the methods counting process, lets say at 50 I need to stop the methods execution, dispose of a few objects and restart it at 51 but have no idea how to go about it.I basically need to raise an event from the method to the main thread and restart the asynchrounous method.
VB.NET 2010, .NET 4/I have a System.Timers.Timer object that does some work on its elapsed event:
Private Sub MasterTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles MasterTimer.Elapsed MasterTimer.Enabled = False '...work... MasterTimer.Enabled = True End Sub
My problem is that the work that it's doing sometimes gets stuck. Part of the work is serial communication so it might be getting stuck waiting for a response from something. I've already modified my serial communication code a bit to hopefully solve the problem. However, this timer is basically the heartbeat of a production control application and it is very bad if it were to stop for any reason. I was thinking that it might be nice to put in a fail-safe timeout so that, if the "work" is taking too long, the timer could re-enable itself and try again. I was thinking of something like this:Move the work into a subroutine and create a delegate:
Private Delegate Sub WorkDelegate() Private Sub Work() '...work... End Sub
Call the work by invoking the delegate and then use WaitOne(timeout) on the IAsyncResult to specify a timeout:
Private Sub MasterTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles MasterTimer.Elapsed MasterTimer.Enabled = False Dim workDel as New WorkDelegate(AddressOf Work)
[code]....
In that it would re-enter a subroutine that is already running? Is there a way to abort Work() if it hasn't finished after the timeout? In other words, just cease execution of Work() if result.IsCompleted Is False after WaitOne?
I need to build an an asynchronous encrypt/decrypt method but I don't know where to begin. I have only one requirement. I need to get a serial number like output for example: ABC12-EFG45-POI98-KJUH8-KJSAK I need to build a minimalistic licensing algorithm, where I want to create a serial number based on a salt, username, machinename etc. My Sharepoint Blog [URL]
I just have a simple vb.net website that need to call a Sub that performs a very long task that works with syncing up some directories in the filesystem (details not important).
When I call the method, it eventually times out on the website waiting for the sub routine to complete. However, even though the website times out, the routine eventually completes it's task and all the directories end up as they should.
I want to just prevent the timeout so I'd like to just call the Sub asynchronously. I do not need (or even want) and callback/confirmation that it ran successfully.[code]...
In Visual Studio, when you right-click a method call, you go to the implementation of that method inside a class except if you access this method through an interface: in that case you go to the interface method not to the actual implementation.Is there a way / tips (key shortcut or anything) to access this actual implementation ? Otherwise you are stuck to add some comment just to remember where you did implement it that's really not productive and error prone !
Update: interesting answers but I'm not really satisfied because all are cumbersome. I will give a precise example:
When form is loading i set webbrowser to navigate a website.
Now this website running too much popup ads.. So each time webbrowser navigate a new popup window open out of my application.. Is their any way to stop that..
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged Browser.Navigate(ComboBox1.SelectedItem)
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 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 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] .....
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 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?
I have an application that allows users to navigate PDF files on a local network. Each time a new document is opened, a tab page is added to my tab control and the webbrowser control is added to it then I call the webbrowser.navigate function to open the file.In windows XP this worked great. However, when switching to Windows 7, it always wants to open the PDF using adobe reader in a new window.
In 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'm guessing there is a really simple answer to this but i've spent the best part of 2 days trying to get it to work and cannot figure it out.Basically, I want is the webbrowser to point to a local folder on a machine. A different one depending on who is logged on. The code I have so far is as follows.
Imports System.IO Public Class frmFav Private Sub frmFav_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim username As String
[code]....
I cannot get the URL value of the webbrowser (FavProgs) to take the value of directoryname. If I set the URL value in the properties for FavProgs it does what I want it to do perfectly.
