Prevent Login Wars Between WebBrowser Controls And Actual Browsing?
Jun 4, 2010
I 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 was wondering if anyone had any resources on vb controls, I'm just a beginner so please excuse my little knowledge. I have been having troubles with the checked listbox control, selectedindex is the method for displaying the checked list position yeah? so what is the method that i need to use the actual vaue that is stored in the checked listbox ( the string ) ?
So I should be able to use "getelementbytagname" right?Also, the formId is logmein (log me in)
<form id="logmein"....
This is what I came up with:
Dim webbrowserDocForm As HtmlElementCollection = WebBrowser1.document.GetElementsByTagName("logmein") For Each curElement As HtmlElement In webbrowserDocForm Dim controlValue As String = curElement.GetAttribute("Value").ToString
[code]....
in the next code it's tagname is "input" or "text"? Because I found:
webbrowserDocForm = WebBrowser1.document.GetElementsByTagName("text") For Each curElement As HtmlElement In webbrowserDocForm Dim controlName As String = curElement.GetAttribute("name").ToString
[code]....
It doesn't give me any errors no more, but it doesn't work either.
For the past couple of days I have been using Visual basic 2008 and learning it.Anyway, I am trying to make a login form that will login to a website with WebBrowser control.and I am noticing that the webbrowser is extremly slow, it takes him about 20 seconds to load a page while mozilla opens it in a moment, why is that?
I have IE 8 installed on my machine; and trying to integrate the "Caret Browsing" (navigation using Keyboard) concept into application which i am planning to develop.My sample application in VB.NET as follows:Form - Form1Text box - TextBox1A Button - Button1A WebBrowser control - WebBrowser1Added following line of code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click WebBrowser1.Navigate(TextBox1.Text.Trim())
Well this script is working partially, when the script submit the login a MsgBox("The login is wrong!") appeared, but when the page load a MsgBox("The login is ok!") appears. Why the "The login is wrong!" is appearing?
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted If WebBrowser1.Url.AbsoluteUri = "https://steamcommunity.com/login/" Then
There 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 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 am working on an application using a form with textbox controls as a menu. Pressing enter while the textbox has focus invokes another form and hides the menu form. The reason for this is a requirement that the mouse must not function at all in thisapplication. Not my idea but it is my job to make it so.The problem I could use some. When the user presses enter on the textbox on the menu form the keypress event is used to invoke the selected data entry form and the menu form is hidden. When the data entry form opens the cursor is supposedto be in the first field on the form but the first controls keyup event triggers and the enter keypress from the menu form is still active so the cursor moves to the second control on the form. Having the enter key move to the next field like tab does is also a requirement.
In the keypress of the textbox on the menu form e.handled is set to True but that does not prevent the passthrough. I realize there are many ways to force this to work as I intend by putting flags and so on in the data entry form but I have many to deal with and would like to find a solution I can apply on the menu form rather then adding code to every data entry form to compensate for .NET deficiencies.
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.
In runtime I'm programmatically changing the forecolor to all label and radiobutton controls placed in the groupbox.
The only thing missing is to set the groupbox text/caption forecolor, but as soon as I do so programatically all controls in the groupbox inherits the font type and color making the text hard to read on the Button controls placed within the groupbox.
I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?
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:
I am trying to log in to [url]... the MSN specifically, and i am able to fill in the username and password box but i can't seem to get vb to click the login button.[code]...
automatic login to a website I want to use webbrowser site login screen, but you do not open the popup site is directed to the main page.How can I solve this problem
I ran onto a problem when i was making login form with GetElementById to enter values into html elements I managed to do all that, but i cant make it to "click" on Login button with InvokeMember ("click") is it maybe because it isnt html element, or
I'm having a problem submitting: <input type="submit" value="Secure Login"> How can I submit by value"secure login". Is it possible? I have tried something like this: WebBrowser1.Document.Forms.GetElementsByName("input").Item("Secure Login").InvokeMember("click") And all the variations with it and no luck.
I am using webbrowser control for automate login in https://www.itslb.com/tms/ website i have written code also but password input box doesnt hold any value username hold this my code like below
Dim frmform As HtmlElement = WebBrowser1.Document.Forms("aspnetForm") frmform.All("ctl00_lnkLogin").InvokeMember("Click") frmform.All("ctl00_txtUserName").SetAttribute("value", sUserID)
recently I've been going through some website login automation and ended up with creating a simple my own browser quite happily, to open websites and login straight away.
But I found out that I can't automate some of the websites I was going for, because the html code of the login forms is not shared and cannot be seen in the source.So I'll give you guys a couple of websites I can't deal with and please advice if it is possible to do stuff with them:[URL]...
I have searched google and couldnt find any answer. Is it even possible to login to a website using background worker without having to use webbrowser?
url...only after you have logged in (because then you can see your collected points)How can I do this? I tried the &password=.... thing after the url didn't work I also tried with [code]this would work but it's complicated because then you'll need to check if you are logged in, log in through webbrowser and then get source page, I think it should be possible faster..also how can I check if the page is completely loaded in a webbrowser control? now I usually go to a webpage and then continue my code in the [code]but this become complicated if I want to go to another website after that because then it starts from the beginning again and I need goto statement, etc this is really annoying and complicated after a while
I'm working on some application that can multiple login to one website right now I'm using webbrowser to login but can only for 1 account how to make it can multiple login? Can I use webbrowser to make it or have to use another method?
I don't have code because I don't know if its possible. I need to make a webbrowser for work that will auto rezie images like internet explore does when it is to big for the browswer, I have done it with vb6 b4 by parsing it into ram and then displaying the image, but I don't know how to do it in vb.net cause the code will not convert. Also I need to have vb.net auto send user name and password to the website its navigating to. The website uses a standard username and prompt window that pops up once you navigate to the web address.
I have created a website that works perfect on my machine but when I posted to the server every thing works but the create user and Login. I know when you run it on your machine it saves users at the Web Site Administration Tool. What do I need to do to make it work on the server.
I am trying to automate login and navigation to a website using the WebBrowser control. I can successfully logon to the site using the wb control but after that I can't seem to get access to the newly loaded document's elements within the same routine. I check for ReadyState Complete and IsBusy but they don't seem to be working. There don't appear to be any frames being used at all so I can't figure out why this won't work. I know that the wb control is successfully logging in because I can see the page load in the wb control. However, after the page loads I try to access the HTMLDocument for the new page (after logging in) and it is either set to Nothing or it's the previous page's HTML. I've tried putting in a Sleep to wait for the page to finish before trying to access the HTMLDocument on the new page but it still doesn't work. If I create a button on my form that accesses the HTMLDocument and click it it works fine. I can't figure out how to ensure that the entire page has finished loading within my routine. I tried putting a switch into the DocumentCompleted event but that doesn't work either.
I'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.
