I wish to connect a database that's situated on centralized server. How do i make use of a home windows form VB.Internet application to gain access to it? Is possible?

How do i conserve a single user entry (e.x== used of Place command)?

Are generally of the aforementioned things possible? If that's the case, how do i start applying them?

Yes, you should use VB .Internet to gain access to a database. You will want to consider things known as "ADO .NET" or "LINQ to SQL" or "Entity Framework" for a number of methods for getting together with the database. There is no shortage of lessons available to get began.

I am afraid the 2nd a part of your real question is unclear. Utilizing a comparison operator rather than an Place command? Please elaborate.
