When starting to automate and application you must initialize an instance of the Application class. Then you must start_() that application or Connect_() to a running instance of that application.

Once you have an Application instance you can access dialogs in that application either by using one of the methods below.

dlg = app.YourDialogTitle
dlg = app.Window_(title = "your title", classname = "your class", ...)
dlg = app['Your Dialog Title']

Similarly once you have a dialog you can get a control from that dialog in almost exactly the same ways.

ctrl = dlg.YourControlTitle
ctrl = dlg.Window_(title = "Your control", classname = "Button", ...)
ctrl = dlg["Your control"]

Note: For attribute access of controls and dialogs you do not have to have the title of the control exactly, it does a best match of the avialable dialogs or controls.
