Interesting. I'd suggest leaving the garphical part out fo now. Once the basic functionality is up it shouldn't be much difficult either(that's what I say to myself always ;) <g>)

You say the containers could be of 20ft, 40ft etc. The 1st imput could be the type/size of container and then calculate the AREA of the container.

Now we come down to goods. If the goods carton are all of one size the job shouldn't be much difficult, though if they are of different sizes we need to get those sizes say in an array and a column of the array could also store the AREA(lxbxh) of the goods carton.

Doing some math here can tell us how many goods cartons can fit in, though it would be criptic for goods cartons of multiple sizes wherein you will have to feed in which ones to give more priority or percentage or maximum numbers etc.

Good Luck,
Kamal
