Error with Simplemapi.py

[Mick Duprez]

I wish I new why google doesn't show nicely aligned python code when
you paste the script.
Anyways, in case this helps someone else you can download the script
fromhttp://www.kirbyfooty.com/simplemapi.py

Ian

First of all, thanks to all involved, this looks like what I need
without re-inventing the wheel.
Sorry to Ian if he just recieved 2 emails, my bad, I need to learn how
to use this board better!

I have a small problem. I get an error I don't know how to resolve,
any help would be much appreciated.
I'm using Python25 on winXP pro and the script from the link above.
Here's the error -

Traceback (most recent call last):
File "<pyshell#10>", line 1, in <module>
mailtest.SendMail('(e-mail address removed)','test','test string','c:
\dbs.txt')
File "C:\Python25\mailtest.py", line 135, in SendMail
cast(NULL, lpMapiRecipDesc), RecipCnt, recip,
File "C:\Python25\lib\ctypes\__init__.py", line 478, in cast
return _cast(obj, obj, typ)

I have had a brief look at the C api for these structs and functions
but I can't resolve it, it is probably something simple.
The piece of code I don't understand though is this -

MapiRecipDesc_A = MapiRecipDesc * len(RecipWork) #size of struct??
rda = MapiRecipDesc_A() # isn't it MapiRecipDesc as declared??

There's some new stuff going on here I don't understand.

thanks for your help,
Mick.

I'm using Python25 on winXP pro and the script from the link above.
Here's the error -

That should be 'c:\\dbs.txt' or r'c:\dbs.txt'

Traceback (most recent call last):
File "<pyshell#10>", line 1, in <module>
mailtest.SendMail('(e-mail address removed)','test','test string','c:
\dbs.txt')
File "C:\Python25\mailtest.py", line 135, in SendMail
cast(NULL, lpMapiRecipDesc), RecipCnt, recip,
File "C:\Python25\lib\ctypes\__init__.py", line 478, in cast
return _cast(obj, obj, typ)

I'm unsure what those cast(NULL, ...) are supposed to do, but they look
all wrong. NULL, as defined on that script, is *not* a C NULL pointer (use
None for that).
(In fact the whole script doesn't look well at all - do you *have* to use
MAPI? can't use SMTP instead? Even if you must use MAPI, try the pywin32
package from Mark Hammond, it has MAPI support and a demo script for
sending mail)

MapiRecipDesc_A = MapiRecipDesc * len(RecipWork) #size of struct??

This declares a new type, an array of len(RecipWork) items, each of type
MapiRecipDesc

rda = MapiRecipDesc_A() # isn't it MapiRecipDesc as declared??

This creates an instance of the above array.

Thank you very much Gabriel, changing the NULL to None did the trick
(it also helps if I reload the changed module after editing! ). Yes
that is an old script and I will look into your suggestions. Basically
I'd just like to use the default mail client (windows or Unix/Linux)
to send simple mail with attachments, this way I can log the
attachments I send to a db for example for document transmittal/
register reports etc.
Thanks also for the code explanations,
Cheers,
Mick.

Glad to see it worked.

Hmmm... altough you may find some MAPI implementation for Linux, it's very
uncommon; consider using sendmail instead, or ask for an outbound SMTP
server and use the smtplib module.

Will do, thanks for your time,
