If your power table is bound to a SQL query, then updating the database will automatically update table. The only thing that could be required for the result to immediately show would be a system.db.refresh()
You can pass values from one Vision window to another using client tags. These act rather like global variables.
You cannot bind directly from one window to another. As @Transistor notes, Vision client tags are the most convenient alternative, when bound bidirectionally in both windows.
A script in one window can also "look up" another window's window object, and then drill down into it from its
.rootComponent property to get a component, and then read/assign values.
