As some of you may know I've been asking some really stupid questions on the forums the last few weeks... So I'm starting from square 1 again.

I think I've gone and confused myself yet again so I'm starting with a fuel monitor. I'm going to give a screen with a couple of text boxes and a drop down box or two. The user will pick a registration number from the drop down box and a fuel type from the other drop down. Then using the keypad on the pda/phone thing enter in some numbers to the text boxes.

Pressing OK at the bottom of the screen will save these values to a table in a database.

I've had a brain fart and can't think how to do any of it so I'm designing the interface, going to create a windows CE database, then write the read/update commands.

Is anybody has any hints/tips or examples to help then thanks a bunch!
