Is your . key stuck? What's the rush is it a school project?
Show us what you've done so far, schematic, code.

Download the data sheet for the LCD you're trying to use, this has all the information needed including flowcharts on how to talk to the LCD. Without knowing what LCD you're using, we can't even provide examples on how to use it.

Do you have the data sheet? Did you take a look at it? If not, the first google hit for HD44780 gave me a datasheet, see: http://www.sparkfun.com/datasheets/LCD/HD44780.pdf
Page 23 even gives you a step by step for initializing the thing, 24 gives you the commands. You just have to send the 8-bit command in two 4-bit nibbles back to back, couldn't get much easier assuming you want 4-bit mode. Otherwise even easier in 8-bit mode, just send the 8-bit command with the appropriate clock pulses.
