If you develop code in VS2008 and use no external components, then there should be on additional licensing required.
If you use external components, the licensing required will be determined by that component's vendors.
How you choose to license the application is up to you.
it sounds like you have very little programming experience judging by the questions you are asking. why not buy a programming book or get one from you library and have a read. or try wikipedia. i'd recommend learning java if youre wanting something that will run on a variety of operating systems. or if youre just wanting to write programs that run on microsoft windows why not download some of the visual studio express editions and learn from there.
i use following statement for increase the date value CurrentDate = CurrentDate.Date.AddDays(NumberOfDay)
above statement add the value of NumberOfDay variable to CurrentDate but also it time component is set to 12:00:00 AM"
for example, if before execution of above statement the value of CurrentDate is following #3/31/2007 5:35:13 PM#
then after execution of statement the value of Current date is following #3/30/2007 12:00:00 AM #
so how can i get the value #3/30/2007 5:35:13 PM# in place of #3/30/2007 12:00:00 AM #

How is authentication and authorisation through forms achieved in VB.NET? Are the membership classes available like in ASP.NET? If not, are there other resources available to facilitate role management or is it a manual process to manage users of Windows applications?
The application I'm developing is fairly standard, it's a CRM application which requires different levels of users, i.e. administrators, general users, super users etc. In ASP.NET I would have used the membership classes to handle this, however, I'm not sure whether these are available in VB.NET (I am new to VB.NET winforms BTW).
Hi I need to kwon how to build a message board using vb.net 2005/2008. I know there a lot of free samples but i just want to know what happens behind so that i can expand my knowlegde on how this is accomplished. If there's any article or link where i can learn how to do this i'll appreciate. Thanks
I'd say the best way to learn how one works is to study the source code of a good one. The best .NET one I know of is YetAnotherForum[^]. It's C# instead of VB but the logic behind it shouldn't be difficult to follow.
As probably a simpler example and as an article, you might want to see this[^]. That's an article describing the discussion board used on CodeProject.
