Account lock Macro

Hi all, This is a macro project I am working on and I am stuck with it. The process that I need to establish through this macro is by connecting to an application that we install from software centre and getting multiple accounts locked at one go. We currently lock the accounts manually on this particular application one at a time which is time consuming. Could you please help me with the correct procedure to be followed to build this macro. Will share more details on the same once anyone contact me.
