Ok, what you need to do is step back and relax. You are trying to do too much at once, and not getting any real understanding and logic before proceeding.
Logical Process to Developing an Application is how I stated before. Determine your output; reports, displays, etc. Determine what your interface with the user and the db would look like. Then from there you know what you would have for fields and tables in the database.
I would assume you have no knowledge of Relational Database Design? You need to learn about SQL and database designs. One place to start is a book. Another is google and websites like :
HERE
Granted this site is tailor to the Web, the principles are still the same.
This will give you a start to SQL. My advice is for the your first time, use Access (if you have it), if not, then use SQL Express.
Master, tempdb, etc are prebuilt databases, with data in them. So that is not what you want. You want to make a new database.
Now when you Expand the tree view in Visual Studio you will get the SQL servers Choice, expand that and you should get the SQL Server that is running on your system. Here you can right click on the Server Instance and Choose New Database, to create a new DB. Then you can expand the database view and get table, views, and stored procedures. Right click on the tables folder and choose New Table.
I would suggest you do some reading first on databases, and design principles. As well as some reading of some tutorials on C# like
HERE and
HERE
It is nice that you have the form designed, but what is the code behind it?
The order I would recommend you do stuff:
1. Learn the basics of C#, and Windows Forms and skim sites like
this
2. Learn about Databases, and relational database design, and why it is important
3. Learn about ADO.Net and how to implement connectivity from your application and the database.
Sounds like a lot, but it isn't. You could learn that by going to the sites I gave you, and doing some google searches, and reviewing the tutorials here on Daniweb (even the ASP.Net ones) over a weekend, and you could easily do some of this things you want to do.
