Welcome to the B4PPC forum.
What kind of help are you expecting ?
Somebody who writes the progrm for you ?
Are you new only to B4PPc, or are you new to Basic in general.
I would suggest you to begin on your own an when you have more precise questions because you don't know how to go further ask these questions on the forum.
In reading the help files
Basic4ppc - Windows Mobile programming and Pocket PC Development you will get a lot of information to familiarize with B4PPC.
In searching on the forum in the 'Share your creations', 'Open Source Projects' or 'Code Samples&Tips' you will for shure find some applications where you can look in how to do it.
For me, the best way of learning has always been 'learn by doing'.
Mr_Gee has already given some advices to begin.
Best regards and I am waiting for your questions.
