FIXED. try import except want lineno from Exception

[Ben Gerblich]

In the file "progfile.py", replace between the print start/end with:
<a more glorified version>
--<snip>--
self.userDefs[searchPath][file[:-3]] = {}
try:
    self.userDefs[searchPath][file[:-3]]['class'] = __import__(file[:-3])
    code = "object = self.userDefs[searchPath][file[:-3]]['class'].%s()" % 
file[:-3]
    exec code
    self.userDefs[searchPath][file[:-3]]['obj'] = object
except Exception, e:
    errortext = e
    for badfile, badlineno, badfunction, badtext in traceback.extract_tb( 
sys.exc_info()[2]):
        pass

    # ask the user to 1.'skip' this MDF continue loading other MDF's
    #              or 2. quit the application
    message = "The Module Definition File has an error.\n\n"
    message = message + "Filename: '%s'\n" % fullfilename
    message = message + "Line number: %s\n" % badlineno
    message = message + "Source Code: %s\n" % badtext
    message = message + "Function: %s\n" % badfunction
    message = message + "Error message: %s\n" % e
    message = message + "\n\nSkip this module, but load others?\n"
    message = message + "\nOr CANCEL the application?"

    response = wxMessageBox(message , "Confirm", wxOK | wxCANCEL| 
wxICON_EXCLAMATION, self)
    if response == wxOK:
        print '   ** Did not load this Module Definition File **'
        del self.userDefs[searchPath][file[:-3]]
    elif response == wxCANCEL:
        sys.exit(1)
