My guess is that the environment (eg, PATH, PYTHONPATH etc) for the new
explorer instance isn't setup correctly - how is the explorer.exe
process started when it *does* work? It's hard to answer without more
info, but Python ends up inside explorer.exe, so the environment that
explorer.exe starts with is important.

other questions
<http://stackoverflow.com/questions/4775020/icon-overlay-issue-with-python#> on
Stack Overflow I have a script that will show overlays on files and
folders based on their "state" similar to Tortoise SVN or Dropbox. Works
great.
My problem is that once I restart the explorer.exe process or the OS
itself and open explorer there are no longer any overlays.
My first thought:
* Have the service that actually manages file state detect that no
requests have come in and just re-register the overlay handler
The problem here is that registration requires elevated permissions
which is acceptable on initial install of the application by the end
user but not every time they restart their machine.
Can anyone suggest what I might be missing here? I have the class
BaseOverlay and its children in a single .py file and register from my
main app by calling this script using subprocess.
|subprocess.check_call("C:\scripts\register_overlays.py",shell=True)|
Is Explorer not able to re-load the script as it is Python? Do I need to
compile into a DLL or EXE? Would that change the registration process?
Here's the registration call:
|win32com.server.register.UseCommandLine(BaseOverlay)|
Here's the class(simplified):
|classBaseOverlay:_reg_clsid_
='{8D4B1C5D-F8AC-4FDA-961F-A0143CD97C41}'_reg_progid_
='someoverlays'_reg_desc_ ='Icon Overlay Handler'_public_methods_
=['GetOverlayInfo','GetPriority','IsMemberOf']_com_interfaces_
=[shell.IID_IShellIconOverlayIdentifier]defGetOverlayInfo(self):returnicon_path,0,shellcon.ISIOI_ICONFILE
defGetPriority(self):return50defIsMemberOf(self,fname,attributes):returnwinerror.S_OK|
Thanks for any help you can provide,
