In EXcel VBA, we can invoke 3 Notepad application windows by:

x = shell("notepad.exe",1)
y = shell("notepad.exe",1)
z = shell("notepad.exe",1)

and obtain PIDs in x, y and z, respectively.


How do we differentiate these differnt windows later when we
need to do things like:

=====================
Application.wait Now + TimeValue("00:00:10")
SendKeys "%EP", True
=====================

Can I do something like:

Application.x.wait Now + TimeValue("00:00:10")
x.SendKeys "%FO", True

Application.y.wait Now + TimeValue("00:00:10")
y.SendKeys "%EP", True

Application.z.wait Now + TimeValue("00:00:10")
z.SendKeys "%EP", True
