COM Error -- Urgent help

[Teja]

HI all,

I have a problem in accesing COM objects in threads. To be precise,
lets assume that I have a class GenericFunction s which is defined as
follows:


import win32com.client , pythoncom, thread
ie=win32com.cli ent.Dispatch('i nternetexplorer .application')
ie.Visible=1


class GenericFunction s:


def __init__(self):
print "In Constructor of Generic Functions"


def MyNavigate(self ,dest):
ie.Navigate(des t)


Now there is another file Main.py which is defined as follows:


import win32com.client , pythoncom, thread
from GenericFunction s import *
obj = GenericFunction s()


class Mainclass:
def __init__(self);
print "In Constructor of Main class"


def threadFunction( self,dest):
pythoncom.CoIni tialize()
d=pythoncom.CoG etInterfaceAndR eleaseStream(s,
pythoncom.IID_I Dispatch)
my_ie=win32com. client.Dispatch (d)
obj.func(dest) # this is gving an error.
pythoncom.CoUni nitialize()


if __name__ == "__main__":


s=pythoncom.CoM arshalInterThre adInterfaceInSt ream(pythoncom. IID_IDispatch,i e)

thread.start_ne w_thread(self.n av, (s,'www.google. com')


Basically, I want to access object of GenericFunction s class inside
threadFunction( ). However I was able to execute
my_ie.Navigate( "google.com "). But that was not I wanted. I am not
knowing where the error is....
Please let me know the solution ASAP...

Thnks for your immediate reply.

Here is the code:

I have a class GenericFunction s which is defined as
follows:

import win32com.client , pythoncom, thread
ie=win32com.cli ent.Dispatch('i nternetexplorer .application')
ie.Visible=1

class GenericFunction s:

def __init__(self):
print "In Constructor of Generic Functions"

def MyNavigate(self ,dest):
ie.Navigate(des t)


Now there is another file Main.py which is defined as follows:

import win32com.client , pythoncom, thread
from GenericFunction s import *
obj = GenericFunction s()

def threadFunction( self,dest):
pythoncom.CoIni tialize()
d=pythoncom.CoG etInterfaceAndR eleaseStream(s,
pythoncom.IID_I Dispatch)
my_ie=win32com. client.Dispatch (d)
obj.MyNavigate( dest) # this is gving an error.
pythoncom.CoUni nitialize()

if __name__ == "__main__":

s=pythoncom.CoM arshalInterThre adInterfaceInSt ream(pythoncom. IID_IDispatch,i e)

thread.start_ne w_thread(self.n av, (s,'www.google. com')

I am getting an attribute error

the traceback tells you what attribute Python was looking for, and may also provide
additional clues. can you post the traceback too? make sure you include all of it.

How many times need you a beating with a clue-stick?

Post the _actual_ code, not something that closely resembles it - in _your_
opinion....

Post the error message!!!!

And before you do all this, read:

OK Ok .. Here is the final code thats giving an error:

GenericFunction s.py

import win32com.client , pythoncom, thread
ie=win32com.cli ent.Dispatch('i nternetexplorer .application')
ie.Visible=1

print "In Constructor of Generic Functions"
def MyNavigate(self ,dest):
ie.Navigate(des t)
---------------------------------------------------------------------------------------------------------------
MainThread.py
--------------------------

import win32com.client , pythoncom, thread
from GenericFunction s import *
obj = GenericFunction s()

pythoncom.IID_I Dispatch)

except:
my_ie = None
print traceback.print _exc(file= sys.stdout)

thread.start_ne w_thread(thread Function, (s,'www.google. com'))


-----------------------------------------------------------------------------------------------------------------------------
And here is the error:

You are using an interface created on the main thread here.

>...
d=pythoncom.CoG etInterfaceAndR eleaseStream(s,
pythoncom.IID_I Dispatch)
my_ie=win32com. client.Dispatch (d)
#d.MyNavigate(d est)
obj.MyNavigate( dest) # this is gving an error.

After all the trouble of marshalling the interface into this thread
you aren't using it. Pass my_ie to MyNavigate. I also had some errors
before changing from thread to threading.
