Hi Roberts,
Thank you for your response.Thank you very much.I am new in the industry.
I tried what you told as first option but it is giving following error...
>>> ses = Dispatch("Lotus.NoteSession",clsctx=pythoncom.CLSCTX_LOCAL_SERVER)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python26\lib\site-packages\win32com\client\__init__.py", line 95,
in
Dispatch
dispatch, userName =
dynamic._GetGoodDispatchAndUserName(dispatch,userName,c
lsctx)
File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 104,
in
_GetGoodDispatchAndUserName
return (_GetGoodDispatch(IDispatch, clsctx), userName)
File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 84,
in _
GetGoodDispatch
IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx,
pythoncom.II
D_IDispatch)
pywintypes.com_error: (-2147221005, 'Invalid class string', None, None)
The Second option you told is like to create my own 32 bit process to
communicate with Lotus, but I am afraid that I have no idea about how to
create q 32 bit process and also how to communicate to Lotus using that.
Please give me some code example and idea regarding that.
Thanks & Regards,
Somnath Naskar
