Converting One Of Sites From Expression Over To VS?

Jan 24, 2011

Situation: Trying to learn Visual Studio and VB. I have been using Expression web to build web sites for several years. But not alot of programing within them.I have started a project using Visual Studio 2010 Pro and am working in VB. I am converting one of my sites from Expression over to VS and want to start using the Code Behind model for all of my web sites on this one and all future sites. I have a simple form that works on my old site but in the new site the I have no idea as to how to set up the Namespace's (System.Text and System.Net.Mail). Does it go on the page with the form or on the VB page? If someone has a good example of how to set up a form for emailing the results I would really appriciate looking at a copy of it.I use VB as I am the most familiar with it. I have no experience yet with Java or PHP.

Useful Sites For .NET Programmers?

Feb 3, 2010

Lately I've had to do a bit of programming in VB .NET. It hasn't been too difficult, but the lack of proper documentation or good tutorials has been annoying me. I'm used to finding a lot of relevant info when I google a programming question, or term, or method name - but it's been more difficult with VB .NET. Anyone know of any good tutorial/documentation sites for VB .NET?

Blocking Web Sites In Browser?

Oct 10, 2009

I am creating a security program. One of its features is that it blocks inappropriate web sites. I might need help determining which sites are bad and which ones are good. If I could 'read' every work that is displayed in the browser then I could tell, but that may come later.

So, I'm looking for some kind of hook that will allow me to cancel the site if needed. It should be able to still be hooked in Safe Mode, as well... I'm sure that this is going to be an easy one!

Connecting Through Https Sites

Apr 26, 2011

I'm creating an API for a particular website. This API will be in the form of a referable DLL. I've tried the normal HttpListner but it errors when getting any data that is through https (basically anything specific about the currently logged in user). I also can't log in using it. My next attempt involved a hidden webbrowser but that is just as hacked up as it sounds (and very glitchy seeing as the WebBrowser likes to interrupt processes that are currently running with its events). I need a system that works and is fast and efficient (I know, I know, kind of a oxymoron). Does anybody know how to do this?I'm using VB.net so any .net code examples are acceptable.

Accessing About 100 Sites At Once Use Classes Or Subs For Each Site?

Mar 1, 2012

I have about 100 websites that I am going to be accessing to scrape some data from (weather, time, etc). When I go to code these babies there will be an abundance of sub routines that I will be creating. They each are going to be accessing pretty much the same type of data.

Should I put them into a Class some how and acces them that way or should I just use Subs and then call them into the Document Completed section of my web browser to run the code? Still sort of confused on the whole Class vs. Sub Routine thing.

App Will Sign Up For Multiple Sites - BackgroundWorker Or WebBrowser?

I have an app that is needs to access multiple web sites and sign up for accounts. I don't want to run them one by one as this would be slow as christmas so I figured that I could setup some sort of background worker and put each process on it's own thread that way the app could run each sign up page at the same time. Would using background worker be the "BEST" option to use for this type of application requirement?
