FWD: [python-win32] coinitialize problem
Hi, I'm extending a Python application that uses several com objects and threads. The origional programmer set the main thread to multithreaded by doing this: * sys.coinit_flags = 0 * import pythoncom This is nessacary because otherwise a com (MapObjects2 from ESRI) can't run in a thread, but now I need to use another com object, which is running in a thread as well. This com object, made by one of our clients, needs to run in a single threading model. For some reason, these two com object won't work together in one application. MapObjects2 works when the coini_flags is set to 0 but then the other com object isn't working and the other way around. I've tried a lot of things to solve this: 1) don't import pythoncom in the main thread -- set the mapobjects thread with coInitializeEx(COINIT_MULTITHREADED) -- set the other trhead with CoInitialize() 2) tried the same things but then with initializing coinit in the mainthread with both models 3) Made a some test programs, but I had always the same problems, except when I made 2 functions for the 2 com objects, and started them with beginthreadex (like described on page 626 from Mark Hammonds book Python programming on win32) and then coinitialize in the functions, but unfortunately, this is not an option in our main program Strange enough, we use 2 other comobjects, adotable for mssql and a com object for sending smses, and these two are always working. Can anyone help me with a solution? and maybe som examples?

return pramater in com object function
Hi,
One of the functions in the com object I need to use has a pointer in one of
it's functions
(object.function(string input, struct * output))
(I've created the struct with win32com.client.Record("structure", object))
I've tried to use the id() function but then Python gives me a message that
it's an int, not a tructure
and when I just give the object without a pointer, the object is still empty
afterwards.
In the mailinglist archive I saw this message from Mark Hammond:
"Well, their IDL is at fault, and it clearly should be marked as [in,out]. All
we should need to do is to get the makepy generated code for this function, and
change the last "type tuple" for this function. It will be a tuple of, eg
(pythoncom.VT_OBJECT, pythoncom.PARAMFLAG_FIN). Telling Python it is really
_FIN | _FOUT should do the trick"
So I opened the by genPy generated file and tried to change the last tuple from
_ApplyTypes_ but it was already 2 (PARAMFLAG_FOUT):
return self._ApplyTypes_(1, 1, (24, 0), ((8, 1), (36, 2)), 'SetIDString',
None,inID, outID)
Does anyone know how to solve this?
Kind regards,
Gijs

re[2]: Com object questions
> Does IPADDRESSSTRUCT appear anywhere in the makepy-generated module ?
Specifically, there should be a RecordMap dict containing any defined
Records
and their GUID's.
No it's not in the genereted module, but it is in the COM Browser so I'm sure
the struct is in the com object
Maybe I can find out somewhere what the GUID's is and put it in the RecodMap
manually?

Hi,
I'm still figuring out how I can use the win32com for the use of a com
object which I think is made in VB
First I've created a file with MakePy
Then I used the following code to init the com object:
import win32com.client
Client = win32com.client.Dispatch("ClientModule.Client")
Then, when I want to use a function, for example this one:
ipaddr = kddClient.GetLocalIPAddress()
I get this error:
File
"C:\Python23\lib\site-packages\win32com\gen_py\0F4570B8-4D39-47CD-84B4-8A424233EEBFx0x1x0.py",
line 69, in GetLocalIPAddress
return self._ApplyTypes_(11, 1, (36, 0), (), 'GetLocalIPAddress', None,)
File "C:\Python23\lib\site-packages\win32com\client\__init__.py", line 446,
in _ApplyTypes_
return self._get_good_object_(self._oleobj_.InvokeTypes(dispid, 0,
wFlags, retType, argTypes, *args),user, resultCLSID)
com_error: (-2147024809, 'The parameter is incorrect.', None, None)
I don't know which parameter is incorrect because the function doesn't need
any parameters
and when I try to use a struct for the IP address using the following code:
ipaddr = win32com.client.Record("IPADDRESS_STRUCT", Client)
I get this message:
File "C:\Python23\lib\site-packages\win32com\client\__init__.py", line 403,
in Record
raise ValueError, "The structure '%s' is not defined in module '%s'" %
(name, package)
ValueError: The structure 'IPADDRESS_STRUCT' is not defined in module
''
I think this means that there is no struct IPADDRESS_STRUCT defined in the
com object but when I'm going to the ComBrowser in PythonWin it is in there.
I'm using python 2.3 with pywin32 build 203
Does anybody know what i'm doing wrong?
Kind regards,

What are com_record objects
Hi, I want to connect to a com object with win32.client. Through this com object a have to connect to an other device with object.Connect(struct IPADDRESS_STRUCT * ip) the struct IPADDRESS_STRUCT looks like this: Byte Offset NameTypeLength (Bytes) Description 0 b1 BYTE1 Byte 1 of an internet address 1 b2 BYTE1 Byte 2 of an internet address 2 b3 BYTE1 Byte 3 of an internet address 3 b4 BYTE1 Byte 4 of an internet address Because Python doesn't have structs like C, I tried to do it with a class (C structs are classes with no private) and with pack but I always get the error message "Only com_record objects can be used as records" I'm new in the python language but I couldn't find anything about structs or com_records in python on the internet. Does anyone know how to do this?

How to debug a multithreaded windowsNT servvice with Boa Constructor
Hi, I'm trying to debug a multithreaded windowsNT service with Boa Constructor but it's not working. I don't know how to debug a service (there's nothing on the internet about that) so I've made an extra module espacially for the debugger which starts all my threads. (if anyone knows how to debug a service, you're welcome to tell me) This module is working fine and I can debug it but when I want to debug the threads it's not working. I used a code similar like this one: import ThreadOne FirstThread = ThreadOne.ThreadOne() FirstThread.start() On the second line, I can walk through the __init__ with the debugger but after that the debugger is not working anymore: The debuggerwindow sais ready instaid of running but the thread is still updating the logfile which means it's still running. I've used both hard (if hassattr(sys, 'breakpoint'): sys.breakpoint() ) and soft (the red dots) breakpoints I'm currently using 5 threads but I've tried a test app with only 1 thread and I had the same problem. I'm using Boa 0.4.0 with python 2.3 and wxPython 2.5.5 Kind regards, Gijs -- This message has been scanned for viruses and dangerous content by Network Sentry, and is believed to be clean. http://www.networksentry.co.za -- http://mail.python.org/mailman/listinfo/python-list
boa can't connect to zope
Hi, I want to debug python applications on a remote pc with Boa Constructor. To do this, I have to install Zope and install the remote module from boa to the roodfolder from the management interface (http://localhost:8080/manage). I've done this, set the username and password en clicked start. the management interface says now "The debug server is active" but when I want to connect to the server with boa constructor I get an error (connection refused) and when I do a portscan on the server, the port 26200 is not open. I'm running win2003 server with python 2.3 and zope 2.7.4. Can you tell me how to open the port on win2003 or tell me what else I'm doing wrong? -- This message has been scanned for viruses and dangerous content by Network Sentry, and is believed to be clean. http://www.networksentry.co.za -- http://mail.python.org/mailman/listinfo/python-list
{SPAM} Remote debugging
Hi, For developing Python 2.3 applications I use Boa Constructor for debugging the application. This is working fine but now I want to debug an application on a remote PC (win 2003 server) installed as a NT Service. I know it is possible with Boa Constructor and HAP debugger but it doesnt work with both debuggers. With the HAP debugger it is possible to connect to the remote pc but it doesnt stop at the breakpoints The Boa Constructor doesnt work at all, when I go to Tools->Attach to debugger and press Ok I get the error message error: (10061, Connection refused) I followed the steps in Boa Debugger help and every thing I found on google: Add the debugger to Zope. Ive installed the source code on the same place at the server and at the client pc (D:\project\) Does anybody know how to do this?
