WebBrowser Control Is Running Into Javascript Error That IE Doesn't?
Oct 21, 2009
If I use IE I can visit the website I want and click the 'Next' button and life is good. If I open that same website using the webBrowser control and click the 'Next button I get a javascript error message.I'm not doing anything in the code to manipulate the website. My goal, eventually, is to have some level of automation; but at this point, I get the javascript error and a pop-up and it screws everything else.
I am developing an Outlook 2007 VSTO application that works with a commercial website.Almost all of the app's interactions with the website are done using HttpRequest objects.One user scenario does require the app to open a browser to a specific page on the site, and that page requires a Post string to provide the results of a form submit.I am using the version of the WebBrowser control that ships with VS 2008, and specifically VB.Net.My code successfully goes to the first page, after which it navigates to the actual target page (once the first page is loaded).That works, too, but if I click on the desired link on the target page, a JavaScript error pops up, stating "'j.parentNode' is not an object", with a Code of 0.I do not have access t the commerical site's internals. The page and links in question, when accessed via IE or Firefox, work correctly without the JavaScript error. The page containing the link is using Flex.Is this a problem with the nWebBrowser control?
I'm looking for a way to run Javascript in an instance of WebBrowser. Ideally I'd like to include a file using [Code] Problem is, the only way I'm seeing to run JS in the browser so far is by navigating the browser to a javascript) url, and I'd like to avoid that. There must be a way to interact with the DOM and add the code that I want to run in there. Right?
i was able to set the name on the form on the page using.[code]ive found lots of ways to use the ID to select but nothing that will work with this javascript(i think it is)as there are no IDs, ive tried everything i could find.just to be clear, the is a webpage im loading into a vb.net 2010 app via the webbrowser control. im trying to change the selected index of the combobox in the webbrowser control to match what i have selected in a combobox control in the same application.
I know how to InvokeScript so my VB form can call a javascript function in the Webbrowser document, but does anyoe know how to do it the other way round - ie javascript calling a vb function in the containing form? Why do I want to do this? Well I've got a table of telephone conversations. Some conversations are longer than others and they look silly in a grid with fixed row height. So I put them in an html document and display them in the webbrowser control. There's a hyperlink on each subject title, and I'd like the hyperlink to open an 'edit conversation' dialog box in my app.
An action that I'm trying to automatically complete on a web page requires me to click "Yes" on a JavaScript alert box. Obviously the entire process cannot be automated unless the program clicks "Yes" or "No" for the user. Is there any way that I can capture this alert box and click "Yes" programmatically?
I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:
I have a Web Browser Control on a User Control that I load into IE problem is doesn't matter what I do, IE says that I cannot access a disposed control.I read the others have had similar problems with various controls, but here is no real answer out there regarding a Web Broswer control. The problem is on line 34. It happens if yout ry to do anything with the control, not just navigating. Also, the User Control does load in IE fine, however, the Web Browser control is never there no matter what I do.[code]
My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]
I have a sample application, in which I am trying to load a text file in WebBrowser control. I have a html file through which I am calling Javascript function to open text file. But it is showing me error like; Cannot find 'file:///C:/temp/test%2520page.txt'. Make sure the path or Internet address is correct. File exist at this location and its name is; test page.txt. I am not getting what is happening.
I have a webbrowser control and the following code is in a for next loop. If I use wba = New WebBrowser the code works in the background and I don't see the loaded pages in the webbrowser control. My question is how can I see the results in webbrowser component with wba=New WebBrowser ?
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted TextBox1.Text = "" TextBox1.Text = WebBrowser1.DocumentText Call baby() End Sub
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol. Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
I'm running a webbrowser control with a custom user agent.When I try to load google with it, there are a number of 'script errors' in the website, which I've hidden by setting 'Scripterrorssupressed' to true. Now however there is still an 'object error' which pops up when i try to load google.Every other website that I've tried loads fine, and when I click 'ok' google runs fine. I'm quite sure its something to do with google 'location services' trying to locate my browser, because it thinks its a cellphone (due to the custom user agent).I've been trying DESPERATELY to fix these errors for DAYS! Is there any way I can just totally hide any popups - hence hiding this? Just any way to hide or stop the errors!
Getting the html source from my webbrowser control. I'm trying to get the source in the DocumentCompleted event of the webbrowser. The code i'm using is this[code]...
I am navigating to a web page with my webbrowser control
[Code]...
and this works on most pages. Now I'm going to a page that I guess there are errors in the page and I get a box asking me if I want to debut in IE's built in script debugger or something to that effect. Is there any way to have the system ignore this message and continue to load the page as normal
I have a javascript function that moves items between 2 select multiple box, when I move item from the source select box to the destination select box, I add the value to my HiddenField so that I can access in code behind, works fine but when I move item(s) from the destination select box back to the source select box, I try to use : hidMemType.value = ""; to clear the hiddenfield. I thought this works but apparently in the event of a postback, the item still gets stuck in the destination box.
// Move items to and fro select box function move(sourceFrom, sourceTo) { var hidOutlet = document.getElementById('<%=hdnOutlet.ClientID%>');
I made a simple application for a website, the site has a IRC-chat and the program should let you close the window (or actually minimize it to the system tray), and then open it from the tray.the problem that occurs, is that I keep getting a Script Error from IE:url...the weird part is that this does not happen when using Internet Explorer on it's own.so it only happens within the WebBrowser Control in the application I made.the application, also, couldn't be more simple, it had just a single window with only a webbrowser control that loads url..., further the program only has a Notification Icon and a Contextual MenuStrip for the Notification Icon.
I made a web browser using the Visual Basic Language. I am having a problem with the WebBrowser Control.If I go to a website that runs scripts (i.e.; sports.yahoo.com), a message comes up:"An error has occured on this script page", Do you want to continue running Scripts on this page "yes, no". If you click yes or no, the same message appears for 8 more times. Is there anycode I can use to disable the "Script Error Message" from appearing in the WebBrowser Control.
I have a question regarding a javascript command. What I am doing is on a asp.net page, a user clicks on a print button which I have another page open up and at the bottom of that page, I put in a simple script command, but I have noticed that my window.close doesn't always work. [Code]

I am new to programming and trying to create an application to login to a website and download a report automatically. I am stuck at the login part. What i have so far:
I'm using Visual Basic 2010 Express and I'm trying to disable JavaScript in one of my webbrowsers and not the others.I've searched around the web for the past hour and haven't found anything that really fits what I need.Also, I already know about the Internet Options dialog. I want to have my program do it programmatically.
there is actually a webpage which i browse using webbrowser control, and that page contains a javascript called download() and contains a link.how can i retrieve the value of that javascript which contains the link?
need it to go to a website, lets say this one.Then I need it to wait 1 second (wich is 1000ms) and then execute thisJavaScript Javascript:alert("Hello!");So the result will be:Open google and then send this popup.
