Hello i am new to programming using Vb.net and we are required to make a web-based application for our thesis ..
Can i make a web-based application using vb.net ?

sorry for my english ..

you can use the same environment but under language ASP.NET thats a web development language.

Yes. Use visual studio. Under file you should see a create new project option, depending on which version you are using, (and if you installed the Visual basic option when you installed visual studio,) you should see a Visual Basic language option. Select /expand this and you will see a ASP.NET Web Application option in the new project dialog. Select this and you have started your project - all your code behind will be in VB.net
