How to import tyle library?

[Volker Hetzer]

Hi!
I'm not sure whether this is the right forum but I don't know of any better one.
The problem is this:
I've just started to use microsoft powershell for accessing COM objects.
Now, powershell is a .net program and does some interop stuff.
I've got two programs I want to access (CAD programs).
Both can be readily customized using VBScript, but I'd like to
have the command prompt capabilities of powershell.
Now, with one program, everything works perfect, but with the other,
VBScript and powershell give different results.
Here's the VBScript program:
set App=getobject(,"ViewDraw.Application")
set View=App.ActiveView
App.AppendOutput "Output",View.Query(128,0).Count

and here the equivalent powershell program:
$App=[System.Runtime.InteropServices.Marshal]::GetActiveObject("ViewDraw.Application")
$View=$App.ActiveView
$App.AppendOutput("Output",$View.Query(128,0).Coun t)

The VBScript correctly executes the Query and gives the proper result
but the powershell script outputs nothing.

What I also saw is that for /some/ objects (like $App), powershell
has type info, but for others (notable the collection) it doesn't.
Is there a way I can tell powershell the rest of the types?
Here's the output for an object the powershell has type info about:
PS R:\$App
Documents : {System.__ComObject}
Visible : True
Application : System.__ComObject
FullName : C:\Mentor\2005EXP\SDD_HOME\wv\win32\bin\viewdraw.e xe

HTMLDocuments : {}
QueueSelectEvents : False
Project : System.__ComObject
CnsFileString :
w:\MGC_ADMIN_HOME\share\2005_SP1\standard\isis\ces _expedition.cns

And here for one it hash't:
PS R:\$V=$App.ActiveView
PS R:\$V

Viewport Block
TopBlock
-------- -----
--------
System.__ComObject System.__ComObject
System.__ComObject

Can I make the types known to powershell?
By the way, when I open the vb editor in Excel and load "ViewDraw.Application"
in "Extras->References" I can see the members and properties of the View
object perfectly well.

Lots of Greetings!
Volker
