ArcGIS 9.2: can I let a Python script use the work space of the current ArcMap file?

[SuiHuang]

Hi Everybody:

    I am writing a python script to perform data validation for data editor using ArcMap, and want to make it into a tool in ArcToolbox.
    If the tool is executed from ArcMap with a MXD file open, is it possible to let it detect the active data connection in the MXD and directly use it to retrieve data?
    Thank you.

Try
import arcpy.mapping
print arcpy.mapping.MapDocument("CURRENT").filePath

Yes, but one cannot evoke arcpy from 9.2, and acgisscripting does not provide access to the arcpy.mapping module.
I do not think this can be done from Arc9.2 in python without accessing ArcObjects.

It should be possible to add some VBA code to either an MXD or a user's Normal.mxt that would set an environment variable to the project's source path. That variable could then be read with os.environ.
