My name is Assaf and I'm a junior programmer in VB. I'm developing an application using VB and Access. It's a POS system that I'm working on. I have completed the entire application but I have no idea what is the source code required in order to open the cash register safe. I have a button on my form which says "Print". Once I click on it, the program should print the receipt and open the cash register safe. What should I do? please I will appreciate your response.
thank you in advance,
p.s. I'm using 2 types of cash registers. One with a serial post and one with a parallel port.
