That is not how this forum works. You tell us what you plan to do and someone will tell you if it works.

Can you do it in Visual Basic? If so I can help, VB is a free download now

VB2005 rocks. I used it for a while, but decided to learn c because everyone else uses it.

Cool. I noticed that visual C++ is a free download too.... What's the catch?

 

[gramo]

They are express versions

You have to use .net to make decent programs.

.net is a pain the the azz.

use a few serial to parallel shift registers connected to the parallel port...

The parallel ports data lines and strobe line can easily be used to clock 8 bits of data into a register array like Marks suggested. You'd simply set up some kind of timer in your C program to send out the next column of LED states one by one at any rate. The shift register wil move one column down the line at a time until they start to 'fall off' of the end. If you want a non-moving display don't use a timer just clock the LED data out as fast as possible. Human eyesight can't keep up with a computer so you're going to only notice a tiny blur before the entire display is updated.

Is some kind of interfacing? If so I have done a project before of using led matrix a 5x8. I used 1 IC and I can form any patterns on the LED, if your interested with it just tell. I forgot the IC and Ill have to check my compilation first. I used the parallel port as the driver for the 5 columns and the IC to the 8 rows. I am only using the data pins of the parallel port, I am using VB.
