The record will be defined in a typelib somewhere, and have named elements.
For example, the win32com test VB code:
Public Type VBStruct
int_val As Integer
str_val As String
ob_val As Object
sub_val As SubStruct
End Type
And VB arranges for that to become a COM record. Python code can then say:
s = win32com.client.Record("VBStruct", vbtest)
s.int_val = -1
(Where vbtest in the first line is a COM object that comes from the same
typelib which defines the struct). The object 's' can then be passed as a
param, where it will become VT_RECORD. Without knowing how the struct is
defined in your case I can't speculate how a GUID would be carried. If it
was a simply array of bytes, then using 'buffer(guid)' will give you the raw
bytes.

Subject: [python-win32] How to create a com_record?
I have a COM server that is expecting a GUID as an argument. The generated
makepy shows that the function is expecting a VT_RECORD. I cannot seem to
pass in the CLSID, I get the following:
TypeError: Only com_record objects can be used as records
I looked at the win32com.client.Record function, but it looks like it will
create another COM object if I give it the GUID.What I really need is to
pass the GUID in to this function as a sort of structure. I "think" I have
to build a struct (using the struct class?) turn it into a buffer and then
somehow convert this to a Record object....Trouble is I can't find any
documentation on com_record objects anywhere....Any ideas?
Thanks,
Kevin
