Re: [python-win32] Querying the VNC Service fails sometimes

[Mike Driscoll]

Kevin,

Also check the permissions on the problem users registry.  I would 
expect that to cause a different error, but it might be worth checking.


Most users are local admins. And it's just been happening for the last 
couple of weeks, so it's likely what Roger said: a corrupt registry 
entry. I tried upgrading to 211 last night and am waiting for that user 
to login again. For some reason, after upgrading to 211, I am getting an 
import error on my wx module. Are these tied together in some weird way?

I forgot to mention that we use Windows XP, Python 2.4 and PyWin32
version 210.

You might want to try build 211.  It uses the API function
GetServiceKeyName instead of manually enumerating the
registry.

However, it sounds like you could have a corrupt registry key.
Try reinstalling the service and see if that helps.

[python-win32] import cx_Oracle in ASP

[Tibor Arpas]

Hi,

I'm trying to connect to database from ASP. I reduced my source to the
following snippet:

<%@ LANGUAGE = Python%>




<%

import sys

for s in sys.path:
Response.Write(s)
Response.Write("")

import cx_Oracle

%>



After invoking the asp page I get the following result:

Not that I can think of, and build 211 didn't add any funky new import
tricks or anything.  However, build 211 is packing the MFC DLL now, so
*that* could be related - try removing the MFC that is installed in the
site-packages\pythonwin directory.  What does the import error say?

[python-win32] FireEvent : comtypes work but win32com fails, why?

[June Kim]

IE's FireEvent works with a single argument, for example,
FireEvent("onKeyUp"). However, it doesn't work with two arguments :
FireEvent("onKeyUp",event).

But It works without a problem with comtypes.

See the following example to reproduce and compare:


file: c:/temp/javascripttest/onkeyup.html



onkeyup

function showmeevent() {
  document.getElementById("here").innerHTML+="[+] "+event.keyCode +"
";
  document.lastKeyCode=event.keyCode;
}









Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from win32com.client import DispatchEx
>>> ie=DispatchEx('InternetExplorer.Application')
>>> ie.Visible=True
>>> ie.Visible=False
>>> ie.Navigate('c:/temp/javascripttest/onkeyup.html')
>>> ie.Visible=True
>>> e=ie.Document.CreateEventObject()
>>> e.keyCode=65
>>> ie.Document.all.inp.FireEvent("onkeyup",e)
True
>>> ie.Document.lastKeyCode
0

On the html document displayed on the browser I see "0" is appended.
The event object that I created with new keyCode didn't get passed.

Now with comtypes:

>>> from comtypes.client import CreateObject
>>> ie2=CreateObject("InternetExplorer.Application")
>>> ie2.Visible=True
>>> ie2.Navigate('c:/temp/javascripttest/onkeyup.html')
0
>>> e2=ie2.Document.CreateEventObject()
>>> e2.keyCode=65
>>> ie2.Document.all.inp.FireEvent("onkeyup",e2)
True
>>> ie2.Document.lastKeyCode
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Python25\Lib\site-packages\comtypes\__init__.py", line 216, in __geta
ttr__
raise AttributeError(name)
AttributeError: lastKeyCode

Accessing lastKeyCode from ie2.Document wasn't possible but the event
obejct is passed successfully -- I see 65 appended to the document.


In summary, there are one big problem and one minor problem. The first
is about pywin32's inability to pass FireEvent's second argument. The
second is about comtypes inability to access Document's attributes.

The minor problem is solvable with:

comtypes.client.dynamic.Dispatch(ie2.Document).lastKeyCode

even though I am not sure if this is the right way.

I can't explain that :(  I've stepped through the code, and it seems we are
passing a VT_VARIANT containing a VT_BYREF|VT_DISPATCH.  I'm afraid I'm not
familiar enough with comtypes to know how it is passing that param.

Mark
