pyArcObjects

Utility Functions for using fine grained ArcObjects in Python and GP script Tools. This module only works on Windows platform. If ESRI ArcGIS installation is not found, an AOError exception is thrown.

Thanks to Mark Cederholm for providing inspiration and sharing ;-)

Example usage:

   import pyArcObjects
   
   try:
        #initializing a license only necessary if the standalone script
        pyArcObjects.InitESRIProductLicense('ArcView')
        esriGeoDatabase = pyArcObjects.GetTypeLib("esriGeoDatabase.olb",sESRITypeLibPath)
		esriDataSourcesGDB = pyArcObjects.GetTypeLib("esriDataSourcesGDB.olb",sESRITypeLibPath)
		# call some sample function code.......
		sPath = "path/to/a/file_geodatabase.gdb"
		pWSF = pyArcObjects.NewObj(esriDataSourcesGDB.FileGDBWorkspaceFactory, 
					  esriGeoDatabase.IWorkspaceFactory)
		pWS = pWSF.OpenFromFile(sPath, 0)
		pDS = pyArcObjects.CType(pWS, esriGeoDatabase.IDataset)
		pyArcObjects.AddMsgAndPrint("Workspace name: " + pDS.BrowseName)
		pyArcObjects.AddMsgAndPrint("Workspace category: " + pDS.Category)
        
    except pyArcObjects.AOError, err:
        # Output the python error messages to the script tool or Python Window
        # or a logging object
        pyArcObjects.AddMsgAndPrint(err.getErr(),2)
        
    except:
        #Unhandled exception occured, so here's the first traceback!"
        tb = sys.exc_info()[2]
        tbinfo = traceback.format_tb(tb)[0]

        # Concatenate information together concerning the error into a message string
        pymsg = "Traceback:\n" + tbinfo #+ "\n"
        pymsg += "Error:\n" + str(sys.exc_info()[1])

        # Return the python error messages to the script tool or Python Window
        pyArcObjects.AddMsgAndPrint(pymsg,2)
