Hello all,

I tried to use win32ole standardlib with an activex control but I got  
‘Library not registered’ error message.  
Here is the code :

require ‘win32ole’  
sf = WIN32OLE.new(‘MapWinGIS.Shapefile’)  
sf.Open(‘C:/cities/cities.shp’)

method\_missing’: Unknown property or method `Open’  
(WIN32OLERuntimeError)  
HRESULT error code:0x8002801d  
Library not registered

The open method is present in the specs and the library is registered so  
I don’t understand.

I’m not familiar with windows programming so the way I use to connect to  
the activex with ruby is perhaps not the good one.

Does anybody know where the problem come from ?

Thank you.

Johan

Johan,

Are you using soleb.rb application? I ran into similar problems on an  
app I  
have been working with. I was able to use soleb.rb to see how things  
were  
actually being exposed by the WIN32OLE libraries and found significant  
variances between “spec” and “actual”.
