Using Pythonwin's COM Makepy utility I created a COM wrapper around an OCX file that's used to communicate with a magstripe card reader. The wrapper was created without incident and I can invoke any "get" type of method without a problem. But whenever I attempt to invoke any of the "set" type of methods I receive an error message that states:
(-2147352567, 'Exception occurred.', (0, 'ctlUSBHID', 'Client Site not available', None, 1000398, -2146827890), None) Googling around I see that this error message indicates an ActiveX control that's being referenced without residing within a container. Not sure if this is something that I can fix myself within the Makepy COM wrapper or if I have to rely on the vendor shipping an updated OCX file. I did see a Python discussion thread where someone else ran into a similar problem and had to wait for the vendor to ship a revised OCX file. Dolphin Smalltalk has a similar COM wrapper utility and the same exact error occurs. The OCX file is ideally suited for Visual Basic but I don't have that compilation environment setup on my workstation to try out. Anyone familiar with such matters? I have contacted the vendor to try to initiate things on that end. But if there's something I can do to circumvent that route using Python I'd give it a go. -- http://mail.python.org/mailman/listinfo/python-list
