OK, I'm proceeding with the library that I mentioned (http://disphelper.sourceforge.net/) and I got nice results. Pablo's package goes directly into the core of OLE/COM automation and it would be too hard to for me to study it and continue with it at this stage.��

An example below loads Word for Windows, makes it visible, creates a new document and writes some text:

| w |
COMEngineAlpha initializeCOM .
w := COMEngineAlpha createObjectByName: 'Word.Application'.
COMEngineAlpha callObject: w setProperty: '.Visible = %b' withInteger: 1.
COMEngineAlpha callObject: w method: '.Documents.Add'.
COMEngineAlpha callObject: w method: '.Selection.TypeText(%S)' withString: 'This is a message to appear in Word document.'.
COMEngineAlpha safeReleaseObject: w.
COMEngineAlpha uninitializeCOM.

However, I'd like to marshall a WideString through uFFI so that I won't loose UTF-8 support, of course the plain (String aString) signature doesn't work ("Cannot coerce arguments"). Is there anything I can do myself (i.e. without poking into Pharo virtual machine complexity) to solve this challenge?

Best wishes,
Tomaz

From your snippets it looks like you want to do COM Automation on Windows.

Maybe you should have a look at:��https://github.com/tesonep/pharo-com

Me too :-) ��Unfortunately, I only have time for 'weekend' projects, and any help is appreciated :-)
��
Regarding the uFFI calls, is it possible to pass Win32WideString in a similar fashion as a String - or where to look to implement that?
