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....

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 ;-)
