Subject: [python-win32] Exiting an embedded script?
Message-ID: <3AF6DCB8.8CBFA2AC@umassmed.edu>

I am trying to exit an embedded script before the end of the script. If
I use sys.exit(), the parent application also exits. How can I
prematurely end the python script without ending the parent application.


I am using PyRun_SimpleFile()

I then check the return of that function but if the python script calls
sys.exit(), my program exits before it can do anything about the error.

Any ideas?

Hello Karl,

I am not sure that I completely understand the question, but how about
putting the code in a function and then use raise to quit the function when
needed?

This doesn't work as you said:

... code 1 ...
if condition:
	sys.exit()
... code 2 ...
	

My suggestion is to change it to:


def main():
	... code 1 ...

	if condition:
		raise "exit"

	... code 2 ...

try:
	main()
except "exit":
	# Allow the exit.
	pass


I haven't tried it under your circumstances; it is just an idea.

WinComs

I am trying to post an event from a python COM server to a VB client. I do 
not know whether it is possible or not. Checked the python win32 book and 
there are no references on events. 

Anyone has any references to direct me to? 

Thanks

Message-ID: <20010510155301.44906.qmail@web13005.mail.yahoo.com>

Hi,

lets say I want to get the security information on a
file. So I do:

>>> o = win32security.GetFileSecurity(r"c:\mingc.pyd",
win32security.OWNER_SECURITY_INFORMATION)
>>> o
<PySECURITY_DESCRIPTOR object at 010E9350>


So what do I do with 'o' now in order to get the
owner? I tried:

>>> s = win32security.SID(o)
>>> win32security.LookupAccountSid(None, s)
Traceback (innermost last):
  File "<interactive input>", line 1, in ?
api_error: (1332, 'LookupAccountSid', 'No mapping
between account names and security IDs was done.')

What am I doing wrong?

Thanks for answering!

I was hoping there was a simple solution in C/C++ to prevent the script
from closing the application on a sys.exit() call and not on the python
side.

Message-ID: <MOENJHKDNFEKIAPIOLEFGEBOCAAA.ldeller@xplantechnology.com>

Hi,
I'm having trouble with the win32clipboard module in win32all-138.
I do the following after copying a bitmap image into the clipboard:

$ python
Python 2.0 (#8, Oct 16 2000, 17:27:58) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
>>> import win32clipboard
>>> win32clipboard.OpenClipboard(0)
>>> print
win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_BITMAP)
1
>>> str = win32clipboard.GetClipboardData(win32clipboard.CF_BITMAP)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
pywintypes.api_error: (6, 'GetClipboardData:GlobalLock', 'The handle is
invalid.
')

Any ideas why I get this exception?  Is this a bug in win32clipboard?  The
clipboard contents will paste correctly into another application (eg
Microsoft Word using "Paste Special" to paste as a regular bitmap)

Thanks!
Luke.

Hi again,
I downloaded the PyWin32 code from cvs and found the problem in
win32clipboard.  It assumes that the handle returned from GetClipboardData
was an HGLOBAL.  This is not true for some clipboard formats such as bitmaps
and metafiles.

I have patched win32clipboardmodule.cpp to handle CF_ENHMETAFILE and
CF_METAFILE correctly, and to generate an "unimplemented" error message for
CF_BITMAP and CF_DIB. (my patch is attached to this email).

Regards,
Luke Deller.

Excellent!  Thanks!  I have checked that in (with very minor changes -
whitespace and the not implemented exception is NotImplementedError rather
than win32api.error)

Mark.
