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 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:

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 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 ?
wba = New WebBrowser
AddHandler wba.DocumentCompleted, AddressOf wb_DocumentCompleted
TheLoginUrl = Items(2) & "/test.php"
wba.Navigate(New Uri(TheLoginUrl))
results.Text &= "Login to: " & Items(2) & vbNewLine

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!

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 am using an asp.net update panel to refresh the content on a page when a menu item is selected.
Within the content that is updated are images which have a javascript reflection function which is triggered with the following line of code:
window.onload = function () { addReflections(); }
This runs fine when the page is first loaded but not when a menu item is selected and the update panel is run.
On previous projects using jquery code I have replaced document.ready with function pageLoad but there is no document.ready on this page.
