[python-win32] IE & DocumentComplete

2008-07-08 Thread aaron 
Sorry if this is a repeat, but the information on the web regarding
DocumentComplete and IE is not helping me find a solution.

I read a 2000 thread that documentcomplete was 'broken'.. is this still
the case?  If not, does anyone mind sending me a snippet of some
working code where it's used?  I feel like I'm running in circles here.

Using the Busy and readyState attributes are proving to be a waste of
time without long pausing to make sure the content is actually
loaded.

Thanks,

[python-win32] Calling COM methods that expect arguments by reference

2009-08-10 Thread Aaron Hoover 
This question is similar to one posed by Mike Graham in a recent  
thread, but I thought I'd see if I could rustle up any additional  
feedback.


I'm trying to called a COM automation object using Python. The wrinkle  
is that the method I need uses arguments by reference to store output  
from its execution. The signature looks like this:


TileGraphic(int FileType, int Margin, intObjMargin, BSTR FileName,  
BSTR DestName, float KFactor1, float KFactor2, int* Rows, int*  
Columns, int* X0, int* Y0, int* XExtent, int* YExtent, long InMemory,  
int* ErrorCode)



The Python code generated by makepy looks like:

def TileGraphic(self, FileType=defaultNamedNotOptArg,  
Margin=defaultNamedNotOptArg, ObjMargin=defaultNamedNotOptArg,  
FileName=defaultNamedNotOptArg
			, DestName=defaultNamedNotOptArg, KFactor1=defaultNamedNotOptArg,  
KFactor2=defaultNamedNotOptArg, Rows=pythoncom.Missing,  
Columns=pythoncom.Missing
			, X0=pythoncom.Missing, Y0=pythoncom.Missing,  
XExtent=pythoncom.Missing, YExtent=pythoncom.Missing,  
InMemory=defaultNamedNotOptArg

, ErrorCode=pythoncom.Missing):
			return self._ApplyTypes_(125, 1, (24, 0), ((3, 1), (3, 1), (3, 1),  
(8, 1), (8, 1), (4, 1), (4, 1), (16387, 2), (16387, 2), (16387, 2),  
(16387, 2), (16387, 2), (16387, 2), (3, 1), (16387,

2)), 
'TileGraphic', None,FileType
, Margin, ObjMargin, FileName, DestName, KFactor1
, KFactor2, Rows, Columns, X0, Y0
, XExtent, YExtent, InMemory, ErrorCode)


I'm somewhat unsure how to call it. If I just pass in variables with  
integer values for the by reference arguments, this is the output:


## All args after 940.0 are just variables containing integers


>>> app.TileGraphic(9, 0, 0, "Test.dxf", "Results", 1.0, 940.0, rows,  
cols,

x0, y0, xExtent, yExtent, 0, ErrorCode)

I have also tried using pythoncom.Missing and pythoncom.ArgNotFound  
per Mark Hammond's suggestion. I thought by reference input variables  
were supposed to be converted to output tuples by makepy. Am I missing  
something here? If I try and execute the method without any of the  
input reference variables, I get this error:


TypeError: int() argument must be a string or a number, not 'NoneType'

Re: [python-win32] Calling COM methods that expect arguments by reference

2009-08-10 Thread Aaron Hoover 

Hi Greg,

I gave your suggestion a shot, but I get the following perplexing error:

TypeError: int() argument must be a string or a number, not 'NoneType'


which makes me think it's still somehow expecting to get those values  
as input even though they're explicitly set to be outputs in the  
generated file.


I'll dig a bit deeper tomorrow to see what I can come up with.

Thanks,
Aaron

Aaron:

From the Python definition you show, PythonCOM is going to treat  
your call-by-reference arguments as output values whether they're  
supposed to be or not.  This is for all the parameters defined with  
type (16387, 2).


When you have parameters identified like that, your Python call has  
to treat them as return values, not as calling arguments.  In your  
case, that means your call should look like   Rows, Cols, X0, Y0,  
Xext, Yext, ErrCode = app.TileGraphic (9, 0, 0, "Test.dxf",  
"Results", 1.0, 940.0, 0) .


Of course, that may not actually solve all your problems.  Mike  
Graham and I had ongoing trouble even after we got the calling  
sequence right, for completely different reasons.   If that happens  
to you, I'm afraid you'll have to get advice from someone much wiser  
than I.  (There are a lot of them monitoring this list, fortunately.)

[python-win32] List of keys and values

2014-02-18 Thread Aaron Reabow 
Hi Guys,

This should be dead simple.

I am just trying to find a list of all of the key value pairs held for each
message.


These are the ones that I have found so far:

   - subject
   - SenderName
   - Recipients
   - TaskDueDate

I am using this simple code snippet

import win32com.client

outlook =
win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

inbox = outlook.GetDefaultFolder(6) # "6" refers to the index of a folder -
in this case,
# the inbox. You can change that number
to reference
# any other folder
messages = inbox.Items
message = messages.GetLast()

then doing this for eample:


for message in messages:
print message.TaskDueDate


i was wondering what else I can get access to for a message?

many thanks in advance,

Aaron

[python-win32] comtypes question: getactiveobject(ie.__clsid) says 'operation unavailsble'

2008-06-27 Thread Aaron Colichia 
New to the pywin32 user list

I've read a couple of articles stating that IE doesn't register with the
ROT.  It was geared toward IE4, but I am not sure if I am running into this
or if I am not doing something right.  I question my syntax because I was
certain it worked once.  Both CreateObject and GetActiveObject take 'progid'
which can be a clsid, or the string representation of the application's
clsid eg. InternetExplorer.Application..

here is what i am trying on xp sp2 ie6-7

from comtypes.client import GetActiveObject, CreateObject

ie = CreateObject('InternetExplorer.Application')

ie.Visible

False

ie.Visible = True

ie.Navigate('http://google.com')
0

(Seems good at this point)

newIe = GetActiveObject('InternetExplorer.Application')

'exception in blah blah'

Windows Error: ( Operation Unavailable )


The same results if I use the seemingly good ie.__clsid

I've also tried passing ie._iid_ and str(ie.__clsid) and str(ie._iid_)

Is this all the same problem with IE not registering with ROT?

Thanks,

Aaron

[python-win32] automatically restart python service after crash

2017-01-09 Thread Aaron Burrow 
I developed a python service using win32serviceutil.ServiceFramework
and PythonService.exe.  If the service
crashes (eg, an unhandled exception is raised) I want the service to
restart.  So, I configured the service to restart
using `ChangeServiceConfig2`. Code looks like this.

```
import win32serviceutil
import win32service
import os

from . import makeWin32Service

win32serviceutil.HandleCommandLine(makeWin32Service.PreVeilService)

service_name = os.environ.get("PV_SERVICE_NAME")
win32service.ChangeServiceConfig2
hscm = win32service.OpenSCManager(None,None,win32service.SC_MANAGER_ALL_ACCESS)
try:
hs = win32service.OpenService(hscm, service_name,
win32service.SERVICE_ALL_ACCESS)
try:
win32service.ChangeServiceConfig2(hs,
win32service.SERVICE_CONFIG_FAILURE_ACTIONS_FLAG, True)

service_failure_actions = {
'ResetPeriod': 60*60,   # Time in seconds after
which to reset the failure count to zero.
'RebootMsg': u'',   # Not using reboot option
'Command': u'', # Not using run-command option
'Actions': [
(win32service.SC_ACTION_RESTART, 1000*5),   #
first action after failure, delay in ms
(win32service.SC_ACTION_RESTART, 1000*5),   #
second action after failure
(win32service.SC_ACTION_NONE, 0)#
subsequent actions after failure
]
}
win32service.ChangeServiceConfig2(hs,
win32service.SERVICE_CONFIG_FAILURE_ACTIONS, service_failure_actions)
except (win32service.error, NotImplementedError):
print "ChangeServiceConfig2 failed to set restart behavior"
finally:
win32service.CloseServiceHandle(hs)
finally:
win32service.CloseServiceHandle(hscm)
```

This does not work with vanilla pywin32. From the MSDN page for
`SERVICE_CONFIG_FAILURE_ACTIONS_FLAG`:

   "If this member [fFailureActionsOnNonCrashFailures] is TRUE and the
service has configured failure actions, the failure
actions are queued if the service process terminates without
reporting a status of SERVICE_STOPPED or if it enters
the SERVICE_STOPPED state but the dwWin32ExitCode member of the
SERVICE_STATUS structure is not
ERROR_SUCCESS (0).

   If this member is FALSE and the service has configured failure
actions, the failure actions are queued only if the
   service terminates without reporting a status of SERVICE_STOPPED.

   This setting is ignored unless the service has configured failure
actions. For information on configuring failure actions,
   see ChangeServiceConfig2."

In order for the process to restart PythonService.exe needs to NOT set
status to SERVICE_STOPPED or set
dwWin32ExitCode to some non zero value.  These conditions are not met
in PythonService.cpp:

```
void WINAPI service_main(DWORD dwArgc, LPTSTR *lpszArgv)
{
  // ...

  start = PyObject_GetAttrString(instance, "SvcRun");
  if (start==NULL)
  ReportPythonError(E_PYS_NO_RUN_METHOD);
  else {
// Call the Python service entry point - when this returns, the
// service has stopped!
PyObject *result = PyObject_CallObject(start, NULL);
if (result==NULL)
  ReportPythonError(E_PYS_START_FAILED);
else
  Py_DECREF(result);
  }
  // We are all done.
cleanup:
  // try to report the stopped status to the service control manager.
  Py_XDECREF(start);
  Py_XDECREF(instance);
  if (pe && pe->sshStatusHandle) { // Wont be true if debugging.
if (!SetServiceStatus( pe->sshStatusHandle, &stoppedStatus ))
  ReportAPIError(PYS_E_API_CANT_SET_STOPPED);
}
  return;
}
```

Presumably we should do something with the return value from `SvcRun`
then conditionally report an error with
dwWin32ExitCode. Here is my patch that gives restarts when `SvcRun`
throws an exception.  The ability to
let Windows handle service restarts is important; I would like to get
this fixed in upstream.
