Hi,
i am developing an application which automatically sends invoices to clients every month. the invoice should bear a stamp from a taxation body. this signature is composed of values generated(hashed)by the device itself. the invoices are designed using a crystal report. how can i get the values calculated(hashed) from the machine and include them on the invoice before sending or how can i send the invoice to the device to be printed and sent via E-mail. Remember it is not physically printed. it should be automatically sent.

let see the code that you are working on.
