Edmund,
If you know which the class name of the app and/or it's title you are trying
to "connect" to, then FindWindow API would be easier.
I assume all the running processes are of no concern to you.

I'm really a rookie with VBA & almost no knowledge of VB.

I've followed
http://vbnet.mvps.org/index.htmlcode...pprocesses.htm , copied
its codes into VBA & successfully run tested it where it return results on
the "processes" that are active in Windows. The results are exactly like
what
I get to see in Task Manager's Tab #2. But this is not exactly what I
needed.

What I actually need is contained within Tab # 1 (tab named: Applications)
in Task Manager. For example, say if there are 10 tasks listed in tab #1
of
Task Manager, how can I get VBA to "Switch To" the task that I needed?

(a) How can I get VBA to list down each tasks in a spreadsheet or by
Debug.Print (the list of tasks' in Task Manger Tab #1).
(b) After achieving the above, how can I get VBA to "Switch To" the task
of
my choice? I need the above steps for assurance because my procedure will
later be using SendKeys to perform data entry on a NON-MS Office based
application.

I'm aware that [Application.SendKeys "%{TAB <repeatition #}", True] can
help do the switching but it's simply too dangerous because it does not
verify if it has activated the intended screen. It will be a disaster if
my
data entry (via SendKeys) is consequently executed on the wrong screen.

Thanking you in advance for the big favor.
