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?
View 5 RepliesIf 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.
View 2 RepliesI 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.

stop1 = 1;

View 4 RepliesI 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 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.

I'm loading HTML into the web browser control, and adding a bit of javascript that hightlights a section of html when the user clicks on the area, by changing the classname. If you know the FireBug addin for Firefox, it's very similar to that. But what I need to do after this, is take the HTML source, and find where they clicked. But when I get the DocumentText of the webbrowser control, it's the original source. Not the source with the added class name.Is there a way to get the source code with the javascript generated html?

View 1 RepliesI know this topic is all over the web, but I seem to have a combination of issues that is either not addressed or I can't figure out that they are addressed. Here is what I am doing. I am using Webbrowser to log into a a website and navigate to a specific page, enter some query criteria and click a "search" button. This button produces a table of files that fit the criteria. I then go through the table,navigating to the file names and compare against my database to see if I want to download. This all works well.
The issue: there is no URL behind these file names. It is a JavaScript. I am able to call the file with invokemember("click") but I get the pesky dialog box or Open or Save. Then I get the directory dialog box.
I have tried sendkeys, trie to capture the Webbrowser_downloadFile event, tried ObjectForScripting(not sure I did that correctly), all to no avail. I have tried to use WebClient, but since I do not have and actual URL for the file, I did not expect it to work. I can navigate to the href attribute, but not sure how to use it.

An action that I'm trying to automatically complete on a web page requires me to click "Yes" on a JavaScript alert box.

View 4 RepliesI 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 website loads the javascript file with <script src="url.js" type="text/javascript"></script> How would I be able to execute the functions I want?
View 1 RepliesMy 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]
