I need to generate pdf documents from a visual basic aplication.
How can i do this?

Wow! That’s a really descriptive title you came up with for your post! Imagine: A “VB” question in the “Beginning VB” forum!

There are many available printer drivers which create .PDFs. You print to the driver, and—rather than causing a machine to imprint a piece of paper—they take that which would have been printed and send it to a .PDF file instead.

In VB, specifiy the 'printer' that you have set up as the access name to that PDF printer driver, and print as you would to any printer.
