[python-win32] install_requires 'pywin32' problem?

[Lynton Grice]

Hey there,

 

I hope someone can help me ;-)

 

I have added "pywin32" as a dependency for a small library I created, but
when it tries to download the "PYWIN32" dependency it dies

 

Processing dependencies for LogosQueue==1.0.0

Searching for pywin32

Reading http://pypi.python.org/simple/pywin32/

Reading http://sf.net/projects/pywin32

Reading http://sourceforge.net/project/showfiles.php?group_id=78018

No local packages or download links found for pywin32

error: Could not find suitable distribution for Requirement.parse('pywin32')

 

I have the latest version of "setuptools" installed, just scratching my head
as to what could be wrong here?

 

Any ideas?

 

Lynton

[python-win32] MSMQ - cannot catch COM_ERROR with"pythoncom.com_error"

[Lynton Grice]

Hi there,

Please help me ;-) I know how to push / pop messages off of a MSMQ, also how
to create a queue etc.but my problem is I cannot seen to catch the
"com_error" when I try create a MSMQ that already exists ;-( The basic code
is as follows:

import win32com.client
import pythoncom
import os

try:  
queue_info = win32com.client.Dispatch("MSMQ.MSMQQueueInfo")  
computer_name = os.getenv('COMPUTERNAME')
format_name = "direct=os:" + computer_name + "\\private$\\test3"

queue_info.FormatName=format_name
queue=queue_info.Open(2,0)  "Dies here obviously as queue does not exist
except pythoncom.com_error:
#Queue does not exist...create queue
queue_info.PathName = ".\\private$\\test3"
queue_info.Label = "New Queue"
queue_info.Create()

I get an Exception raised in WingIDE that says something like
"com_error..the queue does not exist or you do not have sufficient
permissions etc" - something like that.

This is the line in "IMSMQQueueInfo3.py" that it is dying on.

def Open(self, Access=defaultNamedNotOptArg,
ShareMode=defaultNamedNotOptArg):
"""Method used to open a queue. The PathName property must
be specified to
open a queue. Parameters include Access (send, peek, or receive) and
ShareMode (exclusive or all)."""
ret = self._oleobj_.InvokeTypes(1610743835, LCID, 1, (9, 0),
((3, 1), (3,
1)),Access
, ShareMode)


Here is the wingide error


http://www.nabble.com/file/p18586458/error.png 

File "D:\Documents and Settings\Lynton\Desktop\test_reg.py", line 10, in ?
  queue=queue_info.Open(2,0)
File
"D:\Python24\Lib\site-packages\win32com\gen_py\D7D6E071-DCCD-11D0-AA4B-00609
70DEBAEx0x3x0\IMSMQQueueInfo3.py",
line 46, in Open
  , ShareMode)

Any ideas on how I can catch ANY COM type error here? Why would it ignore
the pythoncom.com_error???

Your help would be greatly appreciated ;-)

[python-win32] FW: MSMQ - cannot catchCOM_ERROR with"pythoncom.com_error"

[Lynton Grice]

Hey Tim,

Wow, you are 100% correctthere was something in WingIDE that is not
happystrange

I ran the same code in the standard interpreter and it caught the error
perfectly

BTW: What IDE's do you guys use for Python?

Thanks a million, have a great day!

Lynton

I can't see anything obvious (aside from the
possible dangers inherent in assuming that
*any* com_error means the queue doesnt' exist).
I assume that the -- "Dies here... -- isn't in the
original code?

Does the same thing happen if you run in the
standard interpreter? (Don't know if WingIDE
does anything fancy to intercept exceptions).

If the same does happen in the interpreter, can
you use the traceback module / sys.exc_info to
determine exactly what exception is raised and
how it relates to pythoncom.com_error?
