JavaScript - Best Way To Display XML Information On Webpage?
Feb 12, 2012
I've currently got a service that produces xml files every 10 seconds containing server information. I'm looking for a way to display this on a web page. I have been looking on the web for the best way to do this and it seems that using AJAX would be good as it allows the loading of dynamic content to be done in the background. However how can I use AJAX? Should I add a ASP.NET website to my visual studio project? OR should I look to use javascript & AJAX in something like dreamweaver? I'm very new to programming so i only really have a bit of experience in vb.net.

I am *VERY* new to web-scraping and am trying to scrape some information off of a webpage that is heavily javascript enabled. An example of the page I am trying to scrape from is: [URL] I am trying to scrape the property links such as "322 E 98th St" The text appears on the webpage and I can find the link myself, but it doesn't appear in the page source code.
I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,

I have been searching a lot online but couldn't find a solution for my problem. I want it to refresh every certain interval of time without this message to display. Now Ican't minimize my program because I'm putting an automatic Sendkeys.send("{Enter}") after the refresh to get rid of that message by clicking on "Retry".And If I minimize it the Enter will be executed on the active Window, which might be any other Window.
I hope that you understand what I mean, If not, I will clarify more.

was messing around with web controls and making auto login programs and I have been running across many websites that use java script to code their login boxes for some reason. I was wondering how might I edit the values and click on the sign in button if it is inside of javascript?

I'm creating an application where I want to save a webpage to a file. The webpage has a Javascript function written into it. See below
<html>
<head>
<title>Javascript</title>
[Code]....
There is a reason for this. I will be required to retrieve data from a Javascript API. The API can only display data on the webpage and somehow I have to retrieve it from the webpage.
I'm using Visual Studio 2008 but with .Net Framework 2.0. Haven't tried out 3.0 or 3.5.

I'm using VB.NET 2008. I am building an application which had a webbrowser named "browser1". When I navigate a URL on it like [URL] it successfully loads the page. I am using the code to inject a javascript file in this page.
Dim mScript As HtmlElement
Dim mHead As HtmlElement
Dim jsPath As String
jsPath = (SoftwareROOT.Replace("", "/")) & "/plugin.js"
[code]....
The code successfully creates the new element. But when it is trying to invoke script (the 2nd last line) then it fails to run the script.
Note: File path is OK.Code successfully works with a local page (like "c:est.html")."plugin_main" is a simple function of javascript alert().

I need to add a clock to a web page. The clock needs to be synchronized with a server but I really don't want to have it constantly check the server as the page will be open 24/7 on several PCs. Is there some way to get the time from the server and then use the systems clock to keep it updated and check the server every 15 minutes or so to keep it synced?

I'm trying to pull information from an XML webpage but for some reason it just isn't working. The XML webpage looks a little like
<?xml version="1.0" encoding="UTF-8"?>
<item>
<reqdat>Date and time</reqdate>
<result>Completed</result>
</item>
I want to get the node, but everything I've tried hasn't worked :( I think what I need to do might have something to do with SelectSingleNode but I'm not sure.

I am having a bit of trouble figuring out how to collect a piece of information from a web page. Here is the web page I want to retrieve the information from:
RuneScape - The Number 1 Free Multiplayer Game
I would like to retrieve the first "Price" of the item and collect the price every time I execute the code. I understand how to retrieve the source code of the webpage and split strings but how would I retrieve that price?

I am trying to take specific information from a web page and then process that information so that it can be sent to a label or text box.Previously, I had wanted to do this by using Regular Expressions. I've looked around and it seems that using regular expressions to parse information isn't always the best way because website aren't always coded to standards.Regardless, learning regex isn't working out too well for me. So, I was wondering if there was another way to do this?I was thinking that I might be able to use the web browser control. It would be ideal to be able to see the page in the form, select the information, and then be able to display it.

I need to navigate to a webpage and copy a string of information from it within the shortest possible timeframe. The site has the following written on it:This is the string that you need to apply to your algorithm.
Generated String: 61*76*83*47*69*88*
I want to copy the string from the webbrowser control and place it into a string called "GenString"

What I want to do is to get information which has been stored on a webpage in a hidden field.
I have been able to put information on to a web page using the following
WebBrowser1.Document.GetElementById("email").InnerText = email
WebBrowser1.Document.GetElementById("college").InnerText = coll
WebBrowser1.Document.GetElementById("status").InnerText = status
[Code]....
I have tried various lines of code but non of them seem appropriate for what I want to do. The current line I have got is:
'hidfld is the hidden field on the webpage which I want the info from
findword = WebBrowser1.Document.GetElementById("hidfld").OuterText

Not sure why this isn't working. There is no js error, but it just doesn't set the display property to "block". If I remove the inner most if statement, the display property for the div control is changed when the last radio button is selected from the group.

I am having a issue when navigating to a URL that requires the user to log-in before proceeding. The system we are logging into takes care of going to the log-in page and then back to the page I specified. But when I navigate (webbrowser.navigate = ...) to the web page it locks up the form until the method is complete. But I want to wait in that method until after the user logs in and then the window is redirected, and I want to make sure they got there. I am going to need to do this multiple times during the program. Is there another method I should use? I would prefer to use the embedded web window in VB2005.

I have created a windows form application which goes through Internet Explorer index.dat files and extracts various information (URL's , date they were last accessed etc). I then display this information in a data grid view. From here I would like to be able to click on a URL link and open the web page without activating any active content (such as java script, activex, viruses etc). I have tried to do this using Internet explorer in 'offline mode' with the problem being if the web page requires an online connection it automatically changes Internet Explorer from 'work offline' to online mode. Any better way to view the web pages with no active content?

In my code behind, I need to open a little window that displays another aspx page. I have found many ways to do this in JavaScript, but haven't been able to find a way to do it using VB.Net. Looks like you can call window.open() in JavaScript. Is there a VB.Net version of this call, or is this something that has to be done client side?

Was trying to make a little project which will login to a site. The problem i am facing is with the captcha code display..
Was searching around to get the captcha to the form directly but didn't found anything useful.
So my question is how to display only the area of the captcha on the form instead of the complete form.
Like suppose I want to display only the portion where the logo of Visual Basic .NET Forums - The Exclusive VB.NET Community is located instead of complete webpage.
Application using : VS 2008
Answer expected for : VB 2008 or C#
