how can i make a database by using visual basic , i do not want to connect it to a db, i want to make?

or you can learn XML and write out to an XML file

or you can create a delimited file

Delimited file:

when a user has completed whatever needs completion on your site, you application routines will write that information to a text file. The text file will be appended every time new information is submitted.

A delimited file is usefull if you only want to store or retrieve data. If you want to manipulate data, it's a whole different story.

Then, you'll have to code it all yourself. Go get some books about binary trees, key frame, sorting. You'll have to learn from the beginning how it was done in the '50s because that's the way it's done today.

Then put the information in a file.
