Your idea of the .NET platform is pretty obscured, so I am gonna try to answer these questions as best as I can, but I don't have much time. First off, I recommend reading ASP.NET Step by Step 2008. Moving on.
1) How can I design the webpage the user sees after a postback with html and or the design view? Example, he clicks a button, submits stuff, so now i want another thing to appear,,, All I can do is code in C#/VB for the objects that would then render into the html code? I would either redirect them to a new page, or learn how to bind data to controls. 2) in any case, how does .net know when 2 controls (excuse me if i misuse the words :D ) are siblings, who goes first? for example, if i wanted a panel to have 2 whatevers inside Simple answer, you give them new names and if you want, set a tab order. 3) Where can I find a reference of only the most useful (or at least sorted by relevance) classes in the .net framework for web development? I'm getting kinda lost and overdosed with the msdn help, hehehe No other authority like MSDN provides as much information. I feel that you don't understand what your reading because you don't understand who the whole .NET Framework works. 4) I would like the server to have in a database a more or less updated value of some currency exchange rates. Main question is... should i place in the global.asax a code to get it, and a timer to repeat every X hours? or there's some better way with a windows service to schedule the task? and if so, can it happen in a shared server? secondary question: to get the html of a site, as text, its like opening a file but with the url instead of the name? any better way? Yea I would use Global.asax with a timer to udate the currency times, or you could just request it whenever someone views that page. Most exchange servers have a web service you can use that updates itself every so often, and you wont need to write much code, so look into that. 5) In the most standard logical way to code a website with asp.net, the url stays the same between postbacks? Is there any way, for example, to code a site with partial refreshing (ajax i guess, updatepanels, blah) in which each page has a different url? Either look into URL Mapping or the MVC Framework. UpdatePanels are cool but cost alot of bandwidth so I would use them only when the "price is right".
