Hello Windows Squeakers,

someone asked about a COM library wrapper in Squeak.
So I started a little test to check if it's possible
to wrap the ole32.dll using FFI. A first basic version is 
attached. It' very basic and just tries to wrap the 
COM GUID/ProgID behavior. 

Unfortunately I have a side effect when I use MS Office:
  
  COMGUID fromProgID: 'Excel.Application' 

returns a valid GUID and 

  COMGUID fromProgID: 'Word.Application'
  
returns a zero-GUID (caused by a failing call to) if use "^result" 
at the end of the method COMGUID>>fromString:.

If I change this method to return: "^result asString" I get
a valid GUID for Word and a zero-GUID for Excel.

Is anyone able to reproduce this? If so any ideas about the
reason?

To Andreas: Havent recently looked at the VM sources. When
and how (parameters) is COM initialized in the windows VM 
(calls to CoInitialize() or CoInitializeEx())? 

Thx
Torsten
