I am working with vb.net to making a form that prevents the web broswer on windows internet explorer from navigating to certian pages. The code can't just work on internet explorer because I could make a program with a web browser that navigates. It has to prevent the web browser itself from navigating.

I'm automating a download,and I know the URL to the download page. Well, not exactly. This URL is indeed what I need to use, but the website redirects it to the REAL download page. Unfortunately the redirect only happens if I do an exit sub. That is to say, if I do a loop sleeping one second per iteration, the loop goes on forever waiting for the redirect. But if I branch out of the loop by inserting an Exit Sub in break mode, I can see the redirect occur onscreen. (I can watch the current page in the web browser transition to the desired download page). The trouble of course is that I don't WANT to do an Exit Sub at that point, so what's the solution? Do I need to call Browser.Navigate on a background thread?
View 4 RepliesI am currently building a webbrowser that only loads one page, but I don't want the user to be able to navigate away by clicking advertisement links, as I don't want them to be able to surf the net, clicking links could eventually lead them back to Google to search for what they like if they are clever enough!
View 2 RepliesI have this code to attach a new navigating event to a custom webbrowser control. Here it is:[code..]
I do not know what is happening here, as I have used this code on previous projects before.
I have this code set up to navigate to a certain .html document depending on what's selected from a ListBox:
Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged
HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help" & fileArray(FileList.SelectedIndex, 1))
End Sub
The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change.
All of the paths it's trying to navigate to are correct. I've checked this 1000 times.
I've got a webbrowser. It's prettey advanced, given that I've spent quite a lot of time coding it, and here is my code which will get the Favicon of the current website when a the webbrowser has finished navigating:
frmBrowser.BrowserTabs.SelectedTab.Icon = Controller.GetFavicon(Me.Url.Host & "/favicon.ico")
Sometimes, a user has switched tabs before the webbrowser has finished navigating. So my question is: Is there any way in which I can determine what tab the favicon belongs to and set it to that tab, rather than just setting the favicon to the selected tab?
Here is my code:
Dim TestHeader As String = "Referer: [URL]"
If chkRefferer.Checked = True Then
WebBrowser1.Navigate(cmbUrl.Text, False, Nothing, TestHeader)
Else
WebBrowser1.Navigate(cmbUrl.Text)
End If
Whenever I try and browse to a page with the 'TestHeader', IE opens up and goes to the page.... However, if I navigate to the same page without the additional header, it loads up fine in my webbrowser control.
I need get several values from a HTML Page on a WebBrowser Control. How can I get those values in a TextBox?

I'm instantiating a WebBrowser object and programmatically clicking a button to navigate. Is there a way (property, method, or voodoo ritual) for me to check the browser after it lands on the new page to see 1) the form method that was used and 2) the post data?

View 17 RepliesI 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 15 RepliesThere is PreviewKeyDown but I don't know how to prevent it from passing the keypress to the browser using that method & WebBrowserShortcutsEnabled will disable them but not allow other stuff like Control+C,Control+V and even the delete key in a textbox wont function as well as technically any F keys will not be passed to the flash I have running in the web browser control so the reason for disabling was made moot because the keys still aren't usable in the flash game either because they don't function at all anymore or it has an action already(F5-refresh)How do I disable it without stopping it from being used by the underlying webpage - flash in this example....
Return returns execution to it so it ends up calling keydown like normal, there is no actual keydown event for the webbrowser control or id use that....I cant block navigation because a refresh appears to not call any of the navigation stuff....End stops execution of the whole program it seems, not just stopping that part of code in its tracks...Stop just pauses the program in the debugger....Exit has the same result as return does....
Is there no way to either use PreviewKeyDown to not return execution to the caller....or maybe some kind of await procedure(visual Studio 2011 & its await procedures/async procedures) or something which will never finish... them using it a lot(the F5 key) wont use a lot of cpu while it waits for something that would never happen....Or just any other method which could make this work how I need it....
I have a windows form that have 5 webbrowser control. I also have serveral links of URLs and each webbrowser will open them. My problem is that after all links already opened, when I close my windows forms, sometimes my application suddenly open my default browser automatically and open url that on my URL list. I already tried to make all webbrowser to navigate to "about:blank"to make sure there are not loading any webpage before I close my application but the problem is still occur. This has given me a headache since this problem is not always occur when I close my application.
View 6 RepliesI have a program that autologs itself into facebook and monitors posts to my main page and tells me if anything new comes up. Every minute my program refreshes the page and searches for a new post, if my session is expired it logs itselft back in automatically. If I'm in explorer trying to play farmville and my facebook monitor program is running then I'm forced to log in about every minute because my login at the browser kills my vb.net program session.
Then my vb.net program logs itself back in and I'm out! This behavior doesn't happen If I have two browsers running I can log into both and it doesn't seem to effect the other. I can even have my wife log in from another machine while I'm logged in and It's ok. So The question is why is useing the webbrowser controls in the Vb program any different then just having 2 open and logged in browsers and jumping between the two.
I have searched the forums a bit in search of ways to find out how to prevent Internet Explorer to open when you click on a new window link in a WebBrowser control. I came across a topic with this code:

Another area i am now stuggling with is navigating through records one at a time using a database. I am making a quiz and I want the form to populate one row at a time. When Next button is pressed/called, I want to the next row to populate the form, so on and so forth.Problem is I don't really know how to do that.
View 3 RepliesI am using Windows Forms on VB 2008 Exp. combining with Access 2007 as backend.I have designed a form to use ADODB connection with recordsets to retrieve and display data on label controls on the form.On the Form I have buttons like (First, Previous, Next, Last).... I want to use these buttons to navigate the rows of the recordset.However, I have problem in the codes - when I click the PREVIOUS button, it will tell me that either EOF is true. But if I click the NEXT button, it moves to the next record once.... Clicking on NEXT again, does not move to the next record..

What is the best place (event/procedure) to use the newest record when navigating from record to record on a form.
For example, I want to do a calculation on 2 text boxes that are bound to a dataset. This calculation will be done each time a new record is navigated to.
I am using
VB
webbrowser.navigate(link)
in a timer and that sometime ended up with error and sometime the browser shows a blank screen and keep on refreshing and other times it shows an error and the application stop responding.
It has come to my attention even as a novice programmer, that there comes a time when you need to step it up a notch and take my programming to another level. For me I think that time has finally come in trying to learn how to use classes properly.
I suspect this is a common rookie fear and the leap to move out of the Form1 Class, or off Form1 is a daunting one. I learned how to add new forms many years ago and to get them to interact with one another in a crude manor, but never really mastered the whole concept of classes.

I am developing an intranet site using VB.net 2005. I have a list of reports and their URL's located in a table. The list is displayed to the user using a Gridview control with select turned on. when the user selects one , the selected index changed event triggers looking up the URL from the table and stores it in a session variable. the problem i have is that i now need to open a new web browser window and display the page.
I tried using the envDTE.ItemOperations.Navigate but all of the information provided for this process is written in VB6 and VB2003. In 2005 the DTE proces is not native and when you assigned the ENVDTE.Itemoperatiosn to a shared variable (or any type) and
then try to navigate you get the following error: Object reference not set to an instance of an object.
so i tried to create an instance but when i try:
ItemOp = DTE.ItemOperations or
ItemOp = EnvDTE.ItemOperations
it gives me an error indicating that this is not possible. My quesion is, does anyone have the correct syntax for using the envDTE.ItemOperations.Navigate instruction from Visual Basic.Net 2005? None of the microsoft pages or microsoft books provide correct syntax. Or does anyone have any substitute code that can navigate a user from a protected sub in one page to a new web page?

I'm trying to load a specific game (Kingdoms at war, www.kingdomsatwar.com) into a web browser on my visual basic 2010 project (i dont mind if its a webbrowser, AxWebbrowser or Axshockwaveflash, it just needs to be in my form).
To answer this question you may need to go the extra mile and join the game to try what im asking Ok so details:
I have a few issues when trying this, I create a form with a standard web browser and change the url to www.kingdomsatwar.com , when it runs it will go to the website however when clicking the login button it will go to a black screen with a bit of writing cut off in the top left corner (which i found out was "Page Loaded"), so thats the first issue.
However this can be temporarily fixed by right clicking and going to "forward" or "play". After this you will go to a login screen where you can enter your details, however after this it will load the game with a "cannot connect security" (which may be a game issue, however i need to know how to make the vbwebbrowser work like internet explorer, which will load it).
This game runs in flash, so i need to know if there is any special way to make the vbwebbrowser work properly like the internet explorer version works with the game.
I tried running the game's url itself (using mochigames), which is http:games.mochiad.../play.swf?q=243 , (i have tried this in the vbwebrowser, axwebbrowser and axshockaveflash) and they all won't load the game (they will load the game when not logged in but wont load an account)
I know this is a very specific question and can probably not be solved but if anyone has some spare time, could they create an account and give it a shot. All i need is a form which will load a www.kingdomsatwar.com account on it.
On the main form of my application, I added a menu strip button to it to open another form rcgntn.vb in my application.[code]...
