Using getObject()

[AP]

Hello,

I am trying to create an object and then use the getObject() method to set
my VB object to a running instance of the object within a window in a
windows program that is currently running.

For example: -

Dim A as Game.Application
A = getObject()

The object I want to reference is within an ATL window. Is there any way I
can set object A to reference an object in an ATL window?
Do I need to use API functions such as FindWindow in getObjects()
parameters?
Do I need to refer to the actual dll file instead?

I hope someone can help. My aim is to achieve automation, i.e control the
program with vb code.

Thanks
AP
