Hello,

I have some code that I want to execute when an mdx file opens/closes. I'm trying to do it through an application extension because I also have a python addin which will be used with these files, so figure it makes sense to use the extension also.

Before even trying to get my code working in the extension I just want to simply present a message via python addin messagebox and/or writing a message to the python window in arcmap. And basically this isn't working.

Here is the code I'm trying on open/close:

class MXDWatcher(object):
 """Implementation for PlanningTools_addin.mxdwatcher (Extension)"""
 def __init__(self):
    # For performance considerations, please remove all unused methods in this class.
    self.enabled = True
 def openDocument(self):
    #pass
    print('open doc')
    pythonaddins.MessageBox('open doc','title',0)
 def closeDocument(self):
    #pass
    print('close doc')
    pythonaddins.MessageBox('close doc','title',0)‍‍‍‍‍‍‍‍‍‍‍‍‍

Something else I notice in the Python Add-In Wizard, the "Methods to Implement" do not stay checked after I "Save" and close the Python Add-In Wizard. I'm assuming this is fine and that the methods I check are only referenced once when the wizard saves and creates those code blocks in the .py file.

Any ideas on what I've got wrong here appreciated.

Thanks,

Chris

Ok, figured this one out. It seems that before the extension will work you actually have to load it from Customize > Extensions (duh!):

One last note. Even though in the Python Add-In Wizard I did select `Load Automatically` for the extension.

It did not load the extension. It is listed in the Extensions list but is not being loaded automatically. I checked it out with both Windows 7 and 10, no difference.
