I figured out when this happens. It happens when you try to pass an array
into an arg that requires a Record.
I am really confused as to how this all works, but will start trying to find
some info on what is going on.
Form what I can see, the code in the makepy generated file is trying to take
python datatypes and map them into the required. So I need to figure out how
to use a Record then.
if I do:
s = win32com.client.Record("myStruct", o)
s.myString = "test"
s.myInt = 12
o.myFunct(arg1=("test","test"), arg2=1, arg3=s)
it then complains:
TypeError: Objects for SAFEARRAYS must be sequences (of sequences), or a
buffer object.
Meh
thanks though

This error is raised when the Windows function SafeArrayCreate fails. I'm
surprised this is the case - your arrays are very small - but that is the
only way this error will be raised.
I'm afraid the only advice I can offer is to try and modify the VB test
suite to provoke the same error. You will need vb6 and the pywin32 source
distro to build the test COM object (in com\TestSources), then use
win32com\test\testvb.py to exercise it. That would allow me to reproduce it
here. You might also be able to send me the control, and I could at least
verify the params we are passing to SafeArrayCreate are sane.
