[Alastair Alexander] | Hi ... I'm using pythoncom to create a python COM server | application that needs to be able to return large arrays | to COM client apps. For example, I need to be able to | return an array to Excel that is 500 by 10, with each | element of the array holding a 32 byte string. | | If I run the code for smaller arrays, say 10 by 10, it works | fine. If I allow the server to try to return the entire 500 | by 10 array, pythonw.exe causes a memory access violation and | dies and I get an "automation exception" error message in the | client app. | | I assume I'm violating some upper limit for data transfer | from pythoncom into COM. Anyone know if such limitations | exist? Is there a way around them? Can anyone point me in | the right direction?
OK, no straight answer from me, merely a few hints: This is going to be *very* specific to the pywin32 stuff and Python & Win32 in general. In case you haven't come across it, there is a mailing list aimed at these things: http://mail.python.org/mailman/listinfo/python-win32 While I'm sure a lot of its readers (myself included) also follow c.l.py, it's possible that some usefully knowledgeable ones don't. In particular, Mark Hammond who is the author of the pythoncom stuff: I don't remember seeing him post on c.l.py while he's definitely there on python-win32. (Altho' you've said you're new to newsgroups etc., it's not clear how new you are to Python & Win32; I might just be teaching my Grandmother...) Worth running the code from a straight console, ie not PythonWin / pythonw.exe just in case something there is getting in the way. You didn't post any sample code, but if you could narrow the example down to a few lines with the COM server framework and post it, I at least am quite happy to try to test it to see if perhaps the issue is machine / configuration specific. Other than that, I'm afraid you're down to people with far more knowledge than me of the pythoncom internals. (Which is, let's face it, most people).
