The code from the forum works with version 0.2.1, but not with 0.3.2 or any newer version. I have copied the output of the code for both version 0.2.1 and 0.5.2 to the end of this mail. I think the 'report' he mentions is this: http://sourceforge.net/mailarchive/forum.php?thread_name=302672.78110.qm%40web50206.mail.re2.yahoo.com&forum_name=comtypes-users > > I believe, that this is enough output, because I believe the line > > "DEBUG:comtypes:Release <POINTER(ISensor) ptr=0x9f2170 at c14d50>" > > shows, where the bug originates.

What does it tell you? > If you compare the output from 0.2.1 and 0.5.2 (see below), you will notice, that in version 0.2.1 it stops at "DEBUG:comtypes._comobject:<comtypes.client.DispEventReceiver object at 0x01380310>.AddRef() -> 1", but in version 0.5.2 it continues for a couple of lines, doing garbage collection. (at least I assume that that's what it's doing) And the line that I mentioned above is the first of the lines that are added in version 0.5.2. Maybe some reference went missing during the refactoring between version 0.2.1 and 0.3.2, and that now prompts the garbage collector. But this is really weird, because when testing the GetEvents method with something other than this device, (in this case Internet Explorer) it still works. Here is the output of the code from the forum for version 0.2.1: C:\3DConnexion\Python Test>python read_ctypes.py DEBUG:comtypes.client:TDxInput.Device -> {82C5AB54-C92C-4D52-AAC5-27E25E22604C} DEBUG:comtypes.client:CoCreateInstance({82C5AB54-C92C-4D52-AAC5-27E25E22604C}, clsctx=None, interface=None) INFO:comtypes.client:wrap(<POINTER(IUnknown) object c07990>) INFO:comtypes.client:Does implement IProvideClassInfo # Generating comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0 # Generating comtypes.gen._00020430_0000_0000_C000_000000000046_0_2_0 # Generating comtypes.gen.stdole # Generating comtypes.gen.TDxInput INFO:comtypes.client:Implements default interface from typeinfo <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0.ISimpleDevice'> INFO:comtypes.client:Final result is <POINTER(ISimpleDevice) object c07bc0> SpaceNavigator : Connected!

Neither button events nor sensor events are recorded. My initial thought was, that this is, because the naming convention for event methods has changed, (so maybe it should be _ISensorEvents_SensorInput insted of just SensorInput) but the bug also happens when using the ShowEvents method, which should record any event, no matter the name. ________________________________________________________________________ "50 erste Dates" mit Adam Sandler u.
