Hmm… Does anyone know of a stable Ruby-COM bridge which will let one do  
things like importing DLLs, querying for interfaces and calling their  
methods? Is there anything stable available out there?

Or at least a possibility to call C++ code from Ruby resolving all this  
CoInitilize(), STA and so on stuff?

There are some libs:  
[http://raa.ruby-lang.org/cat.rhtml?category\_major=Library;category\_minor=Win32](http://raa.ruby-lang.org/cat.rhtml?category_major=Library;category_minor=Win32)

See also  
[http://www.google.com/search?q=ruby+win32](http://www.google.com/search?q=ruby+win32)

I haven’t used any of those but you can find examples by searching the  
archives of this newsgroup / mailing list.

Kind regards

For just DLL, look no further than DL (in the standard library), for  
OLE (a COM ancestor), check out Win32OLE (also in the standard  
library). I have used both in the past.

Good luck
