Hi Sebastián, Apologies for the delayed response, it's been a busy month. I'm not sure which DirectShowLib you're using (Google has a few options) so I'm basing this on code from https://github.com/larrybeall/DirectShowLib/blob/master/DirectShowLib/DES.cs. > > This is the script I'm using to test: > > --- > import clr > > clr.AddReference('DirectShowLib') > > from DirectShowLib.DES import IMediaDet, DESError > > > class Detector(IMediaDet): > def __init__(self, *args, **kwargs): > super(Detector, self).__init__(*args, **kwargs) > > > mdet = Detector() > > print('Detector: {}\n'.format(mdet)) > print('Detector dir: {}\n'.format(dir(mdet))) > print('Detector.put_Filename: {}\n'.format(mdet.put_Filename)) > print('Detector.put_Filename dir: {}\n'.format(dir(mdet.put_Filename))) > print('Detector.put_Filename.Overloads: {}\n'.format( > mdet.put_Filename.Overloads > )) > print('Detector.put_Filename.Overloads dir: {}\n'.format( > dir(mdet.put_Filename.Overloads) > )) > print('Detector object is instance of IMediaDet: {}\n'.format( > isinstance(mdet, IMediaDet) > )) > mdet.put_Filename('VID_20150207_133726.mp4') > --- > > And it prints the following information, finally throwing an error when I > try to use the method: > I don't know how smart IronPython's COM integration is (DinoV wrote it) but it's possible its converting the put_/get_ methods to a property? Try just calling Detector.Filename and see if that works. - Jeff _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org https://mail.python.org/mailman/listinfo/ironpython-users
