Dowloading data from Pocket PC

Question

Hi,
I am using a Personal Digital Assistant (PDA) to collect researc data. I have created the forms for my questionnaires on the Visual basic. net. I have created a database in Ms Access to connect to these forms and controls.I have further deployed the forms to run on the PDAs. My questions are;
a) How do i save the forms and tables on the PDA from VB.net and use them in the field
b) As the data is being collected, how do i view the tables or my data
c) How do i download the data from the PDAs onto my laptop for analysis

Thanks

Vincent
