Question A simple code

[fa00026@surrey.ac.uk]

Hello,

I am a beginner in Vb.net actually I have a simple problem ..

I need to build up a program that shows 20 pairs of images to 30 people :
before showing the images the person must have a unique number that identify him.
Then each pair of images(A and B) will be viewed to the user for only 3.42 seconds and the user most choose one image of this pair within that time only and he is not allowed to rechoose again, then he must also enter a comment on the images he had chosen he had chosen, then he will move to the next pair doing the same process, until finishing the 20 pairs.

simply that is all , after this I need each user's unique number and all what the users have chosen for the whole 20 pairs, I would like to have the data in Ms Access as a data base to keep all these data for example:

User number pair choice comment
------------- ------ -------- ------
1 1 A balbalbla
1 2 B blabla
1 3 B blabla
:
:
:
1 20 B blabka
2 1 B blabla
2 2 A blabla
:
:
:
:
2 20 A blabla
:
:
:
20 20 B blabla

And every time a user will run the program he will get a new unique number.
I hope you can give me the code for it, appreciate really your help
