Hi! I am trying to use an ActiveX control (.OCX, from a piezo electric stage controller)) from a Python program. I have managed to get the control to work, but I am having problems calling a method.
This is the method in question (from the autogenerated typelib): === DISPMETHOD([dispid(20)], c_int, 'GetControlMode', ( [], c_int, 'lChanID' ), ( [], POINTER(c_int), 'plMode' )), === This is what I am doing trying to use the method (it should give me an integer): === mode = 0 mode_ptr = cast(mode, POINTER(c_int)) try: piezo1.GetControlMode(APTPiezoLib.CHAN1_ID, mode_ptr) except Exception, e: print "Exception:", e === And I get: === Exception: Cannot put <comtypes._safearray.LP_c_long object at 0x012D9440> in VARIANT ===i I have no previous experience with comtypes or ctypes (or Win32 programming, for that matter ;-)), so I might be doing something stupidly wrong. I've tried all the permutations I could think of already, so I need expert help. Thank you very much! Bye & Good Luck!
