Draw and save graphics

Question

I need to make a small application in asp.net where user could draw a small drawing and that drawing is saved in the database for later review.

I have no idea where to begin from. Could you give me a hint please? Thanks

if you mean that the user need to draw on the browser, then you first need to ask for javascript, and check for the "canvas". — Aristos, Nov 29 '11 at 08:00

Use System.Drawing for creating image (lots of tutorials online).

Then you can save image to DB (SQL Express, MySQL?) or maybe better save it to disc with some generated filename and save only path to DB. If you don't know how to access DB then you should first choose one. I recommend SQL Server Express.
