Hi,

I have an existing Windows application which provides an OLE
Automation (IDispatch) interface. I'm not able to change that
interface. I'd like to call it from a scripting language. I figure
this would provide a nice quick way to invoke on the app.
I initially tried this with Windows Powershell but ran into the
following problem. I was able to create the object and invoke simple
methods on it. However the interface for this app has methods which
take out params. i.e. you pass in a reference to a variable and the
server fills in the value. I couldn't get that to work. I finally
gave up and decided it was just a limitation of Powershell, not being
able to work with those out params.

Before switching technologies I'd check if this solves your problem

TL;DR IMHO "out" parameters are basically pointers (pass by reference)
and need to be passed like GetSettingValue("name", [ref]$value)...
cheers
