Thanks Mark. I'll dig around the various windows typelilbs and see if one of them has a GUID structure.<br><br>If
I know the order of the structure myself (and know how to turn in to a
buffer) does anyone know how I could convert the buffer in to a com_record ?<br><br><div class="gmail_quote">On Feb 1, 2008 12:34 AM, Mark Hammond <<a href="mailto:mhammond@skippinet.com.au">mhammond@skippinet.com.au</a>> wrote:<br>

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.</span></p>

<b>Subject:</b> [python-win32] How to create a com_record?</span></p>
</div>
</div><div><div></div><div class="Wj3C7c">
<p> </p>
<p>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:<br>
<br>
TypeError: Only com_record objects can be used as records<br>
<br>
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?<br>
<br>
Thanks,<br>
Kevin</p>
