Detecting JavaScript HTML Page Modification In WebBrowser Control

Jul 23, 2010

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]

Webbrowser Control - HTML Page With Embedded JavaScript?

Jun 5, 2009

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:

VS 2008 : Get Javascript Generated HTML From WebBrowser?

Jan 15, 2011

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?

JavaScript Error Using WebBrowser Control Ion

Jan 23, 2010

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?

Forms :: Javascript Callback To Webbrowser Control

Sep 15, 2009

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.

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.

From HTML Content In A WebBrowser Control, Call Another Control?

Feb 20, 2010

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

Setting The HTML For WebBrowser Control?

Jan 26, 2011

I am currently trying to be able to set the HTML in a WebBrowser control. The bit that I am having the trouble with is that when I go to put the HTML in the WebBrowser control on Form.Load or Form.Activated the WebBrowser1.Document.Body is Nothing. This means when I try to do; WebBrowser1.Document.Body.InnerHtml = value I'm getting an exception as I am trying to use it.I have also tried setting the HTML on the DocumentCompleted event for the WebBrowser control, but that event doesn't fire when I load the form (to be honest I didn't think it would but it was suggested somewhere on the Internet).

ActiveX Control Using VB6 - Cab File And Html Page

Jul 25, 2011

I've developerd an ActiveX Control using VB6. I've also developed its installer .cab package for web. A simple html code is given below that explain how i use that package in html page

<HTML>

<HEAD>

<TITLE>MyAcrivexControl.CAB</TITLE>

[CODE]...

<!-- If any of the controls on this page require licensing, you must create a license package file. Run LPK_TOOL.EXE to create the required LPK file. LPK_TOOL.EXE can be found on the ActiveX SDK, [URL]. If you have the Visual Basic 6.0 CD, it can also be found in the ToolsLPK_TOOL directory.

The following is an example of the Object tag:

<OBJECT CLASSID="clsid:5220cb21-c88d-11cf-b347-00aa00a28331">

<PARAM NAME="LPKPath" VALUE="LPKfilename.LPK">

</OBJECT>

[CODE]...

In ideal situation whenever i run this page by typing url like [URL]. it should ask me for download and install the control, but it didn't.

VS 2005 Want To Load Some HTML Into A WebBrowser Control

May 18, 2011

I want to load some HTML into a webBrowser control, then operate a particular bit of code when it has finished loading.The code operates fine as long as I pause to wait for it to finish loading. If I just run the code without pausing, it sometimes messes up the display. webBrowser.Document Completed doesn't run after Document.write.I don't want to use webBrowser.DocumentText = "..." because that makes an annoying click sound every time it refreshes. A lot of people are annoyed by this. There are countless threads asking how to turn off the click, and using .write seems to be the only solution that doesn't require hacking the registry.
