Re: [python-win32] (no subject)

I'm sorry, but you are very unlikely to find anyone on this list with 
erwin experience. pywin32 is a general purpose library that allows 
talking to *any* COM object, so there are literally hundreds and 
hundreds of different apps it can work with. I've never even heard of 
erwin and have no idea what it does :( You might fine someone else on 
this list has, and can help you, but in the meantime...


You really need to find support for the erwin app, not pywin32. Because 
COM works in any language, you might find the help you need is written 
in terms of a language other than Python, but the answer should 
translate across to Python.


Good luck,

Mark

Below is my code where i am trying to access and erwin datamodel , 
check connection and close connection.


i/mport win32com.client as win32

# Create an instance of the erwin API
erwin_api = win32.Dispatch("erwin9.SCAPI")

# Connect to erwin Data Modeler Mart or local repository
# Get the PersistenceUnits collection
persistence_units = erwin_api.PersistenceUnits

# Open an existing persistence unit
existing_persistence_unit = persistence_units.Add(r"D:\\testdm.erwin")
print("Opened existing persistence unit:", existing_persistence_unit.Name)

# Close all persistence units
persistence_units.CloseAll()
print("Closed all persistence units")

# Save changes to all persistence units
#persistence_units.SaveAll()
print("Saved changes to all persistence units")/

Can you please let me know, what is the correct method if CloseAll is 
not the correct method.
Is there any link where I can get all the methods of 
erwin_api.PersistenceUnits ?


Thanks,
