View 1 RepliesWebBrowser Control Won't Execute Java Applet?
Jun 19, 2009In the process of upgrading one of our applications, it was decided that the users needed an image viewer. We already have a browser based application that does a great job at that task. Since a lot of time and effort was put into the browser based code, I really want to use our browser based viewer rather than write new code to do the same.So, I've added a WebBrowser control to a form and figured I will call our Java applet from there and not re-invent the wheel.

View 4 RepliesJavaScript Error Using WebBrowser Control Ion
Jan 23, 2010I 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?

View 3 RepliesForms :: Javascript Callback To Webbrowser Control
Sep 15, 2009I 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.

VS 2010 WebBrowser Control - Responding To JavaScript Alerts
Nov 27, 2010An 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?
View 4 RepliesWebbrowser Control - HTML Page With Embedded JavaScript?
Jun 5, 2009I 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:

WebBrowser Control Is Running Into Javascript Error That IE Doesn't?
Oct 21, 2009If 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 4 RepliesDetecting JavaScript HTML Page Modification In WebBrowser Control
Jul 23, 2010My 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]

View 1 RepliesDownloading File With WebBrowser And JavaScript Without Dialog Boxes?
May 21, 2012I 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.

Javascript - Iframes, Child Pages And Functions
Jun 20, 2011I have an aspx page with some controls. One of which is an iFrame, whose source changes (depending on the selection in a listbox). So, if a user selects an item in the listbox (ie: Claims.aspx), the iFrames source changes to "Claims.aspx".
Now here comes the tricky part. I have a button on my 'child' pages (ie: Claims.aspx). I'd really really really like to have that button execute either:
1) Javascript from the 'parent' page
2) A VB function in the code-behind of the 'parent' page
Any way to do this? (and really, why do I suddenly feel like I'm working with VB 3.0?

View 2 RepliesExecute Click Using WebBrowser?
Apr 16, 2010I am trying to automate a web page via the weBrowser and the button that i'm trying to click has no ID only a value. here's the html code for it: "<button class="buttonf" onclick="window.location='staticpage.php?accept=123456' ">Accept</button>"
I can't useGetElementById as the button has no ID. If I do
HtmlElement goButton = this.webBrowser1.Document.All["Accept"];goButton.InvokeMember("click");
My script stops showing a nullreference error highlighting the "goButton.InvokeMember("click");"
[Code]....
My script give me an "Sequence contains no matching element" error at the "HtmlElement submitButton" line and sometimes the page has more than one of these Accept buttons, so I would need to be able to tell the difference between each one as well or at least be able to click on one without the script breaking
