VS 2008 - How To Gather Links To Member Websites Automatically
Apr 10, 2009
I'm trying to get my program to go to the memberlist.php of a phpBB2 forum and gather all the links to the members websites.
Example: [URL]
I want the program to go to that website and save all of the websites (the ones that have the "www" image) to a list inside the program. I have no idea how to do this, but that's not all, considering most forums have several pages of members (this one has 32 at the moment) it has to go through all of the pages and gather all the links from every page..

I'm trying to build a small application that will automatically visit a few websites. The list of the websites I want to be stored inside a txt file like:
website1.com
website2.com
website3.com
and when I press the "Start" button, my application will open the websites from the txt file, one by one with a delay of 10 or more seconds before loading the next website, in a webbrowser control.

I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

I'm trying to write a program that will take emails that I have saved from outlook as text files and scan it for specific data, and return those strings to a textbox (i will modify it so it outputs the exact way i need it, i just need to grab that info faster than it takes by hand). I dont know how to go about actually grabbing that specific data.

There can be only one grouping (denoted with asterisks, they are separated in the emails like that as well), or 50 and any number in between. I only need the information as shown in the text file example above (sometimes, it is blank or not there - if that's the case just skip and messagebox.show to alert me that it was skipped).

my webbrowser navigates to a webpage. I need to store all the links into a collection, I did find the code to do the job (on this forum) and it works, but there is a problem: there are more links on the page than those the code reads, like when i right click on a picture and choose "copy shortcut" I get a link that is not showing when I display the "view source" for the entire page. I can't figure out how to do it.

I'm currently using a webbrowser control to extract information from multiple websites. At any given time, my application could be searching through 1-80 different webpages across 1-4 different websites. On my computer, it runs pretty quick. I could go through all 80 sites in just a few minutes. But when on another machine with fewer resouces, it runs awfully slow. Taking up to 15 minutes. Which kind of beats the purpose, but not entirely, of my application.
I'll begin by explaining my methods, and go from there. When utilizing the Webbrowser control, I use While statements and Application.DoEvents, instead of the Webbrowser controls's DocumentCompleted event. I'm wondering if this is one thing that could be slowing down the process. Though I'm not sure why it would be. Also, would utilizing separate threads help with this? I can't imagine it would boost performance. But I'm not entirely sure. I think it bogs down because the application uses so much memory when running. On idle, the application uses about 9.5k memory. When running, I've seen it go as high as 110k.

I read some posts in the vb.net forum for how to modify your host file on your computer adding the domain website to block. this worked great. Then i went to a website such as vtunnel.com and was able to view the blocked website through it. So to still block it I need to add [url]... to the host site as well as any others?

I have the following code which sets internet explorers proxy settings to what ever i want and if i set it to use a proxy ip and port i get a 'Page can not be displayed' error. If i reset it back to the bloxx server again which is: http://gc-bloxx:8080 Then it works fine. What i am asking is, can i get the app to connect through 'http://gc-bloxx:8080' and then set the proxy ip and port so the app can connect to the internet and then unblock the websites?

I'm using Visual Studio 2008 on an XP machine and am trying to develop a web app that can interact with websites and carry out automatic tasks.One problem I have is trying to recreate the web requests for automatic interaction.
For example:I use a webBrowser control to allow me to surf a page manually. Then, once I am at a specific location, I'd like the automatic interaction to take over.Part of the website requires a log-in and exchanges cookie data.When I try to read the cookie info from the webbrowser control to build the subsequent automatic requests, the cookie content is incomplete.Upon further investigation, it appears that the site sets one of the cookies to "http only". This stops the value being visible to the webbrowser control.Is there another control or method I could use to retrieve this info?

It gets the value of the link the files are (the hyperlink) and allows me to download the file, but I want to get to get the string assocaited with it as well
For example, A link says click here! and bring you to a page.
I can get the link to the page, but not the text click here according to my source code.

I'm trying to write a function that can retrieve all the links from a webpage. I'd like to send only a string containing the URL. Basically, given a string of a URL, I'd like to "load" that into an HTMLDocument so I can access the Links collection. I just can't figure out that part.I've already written the function by using the Document in a WebBrowser. But, after selecting a link, I'd like to get its links, and so, and so on....while the user is still browsing the first page.

I've got URL's appearing in a RTB as underlined and blue. When you mouse over them the mouse pointer changes to a HAND.
But clicking does not launch a browser and bring you to a webpage - how do you make that happen?
