I am doing an account editing application.
I had like my applications to be doing on the same account, be it in my main form or in other forms (debit, credit, paymen etc), but still doing on the same account.

So, how can I implement my form/code to be doing on the same account unless user selected other accounts, throughout the whole app?

I heard and seen that arguements or methods in your coding, how do you do that?
