embedded python in dll with C
Hi All,
I can't quite get my head around embedding Python in a C app and I
have a few questions if I may, here is the background.
I want to create a dll plugin that has the Python interpreter embedded
in it for use in scripting an established application. So far I have
created the interface dll and py module using swig. So far so good,
now some questions -
1) Would it be best to combine my swig generated .c file into the same
dll as my plugin dll or leave it seperate, in other words should I
just embed the interpreter into the C 'plugin' dll and create the
interface module and dll seperately to import into python scripts?
2) Once I have done this would it be appropriate just to use something
like this in my C code -
PyRun_SimpleString("import my_plugin_script");
PyRun_SimpleString("init_func_from_script()");
where 'init_func_from_script' establishes callbacks for C to use from
the script using the new interface module/dll? The C application has
it's own functions for registering callbacks by passing in a list of
the functions, I'm hoping this will work.
I'll give it a go in the mean time, just looking for the right/better
way to do this, thanks.

Python command line error
Hi All, I've installed Python 2.5 on a number of machines but on one I'm having problems with the CLI. If I fire up the 'cmd' dos box and type 'python' I get a line of gibberish and it locks up the cli, if I run the 'command' dos box I get a few lines of garbage and it crashes/closes the dos box. I've tried a re-install, checked my system paths etc but I can't get it to work, it works ok for running scripts from a dbl click in explorer for instance and from Idle, I just can't run scripts from the command line. I have installed - xp pro sp2 Python25 wxPython2.8 unicode PIL numpy any clues to what's causing this behavior? tia, Mick. -- http://mail.python.org/mailman/listinfo/python-list

I have cygwin on this machine also and the cygwin/bin path was before the Python25 path so it was playing up, I put the Python25 path before the cygwin stuff and it's fixed. It's always something simple! Cheers, Mick. -- http://mail.python.org/mailman/listinfo/python-list
Error with Simplemapi.py

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 -
>>> mailtest.SendMail('[EMAIL PROTECTED]','test','test string','c:\dbs.txt')
Traceback (most recent call last):
File "", line 1, in
mailtest.SendMail('[EMAIL PROTECTED]','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)
ArgumentError: argument 1: : wrong type
>>>
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.

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.
