I just created a points Shapefile, with 300 points.
Using ArcGIS Desktop 9.3 I now need to label all of them numerically.
Is there a way of labelling all of them, instead of me going to the attribute table and label them manually?

I have created a script for ArcGIS 9.3 that uses a point dataset to create a polyline dataset with the points' attributes. The tool allows a user to select a field name from the points layer to group the line segments, a field name to sort the groups (optional), and the point layer fields to be copied to the line layer. Line segments are created from two points with the same attribute in the group field. The attributes for the line segment are taken from the first point. The points DO NOT have to be sorted by group attribute and order.
The points can be grouped by numeric, string, or date fields and can be sorted by numeric or date fields. Point datasets stored in SDE geodatabases cannot be grouped by a date field, but can be sorted by a date field.
There are 2 scripts at work.
First creates attachment – text file - in data driven pages polygon stored in FGDB, name in TOC = Pages.
Data sourced into attachment table from layer called ‘pnts’, it has to have page definition query active. To control appearance of future table you’ll need text element in your layout called TABLE. This is what tool expects as parameters:
The values in field list are field names from ‘pnts’ that you want to show:
Yes you have to change list to suit you needs.
Script iterates through pages and does:
- Remove existing attachment
Create attachment from values taken from pnts table within current DDP.
(I usually create a small buffer around pages, intersect it with pnts. This create 2 pnts where buffers overlaps)
I use is Calibri Light font for text in the TABLE.
Script:

fileO = open(fOut, 'w')
fileO.write(textB)

arcpy.AddAttachments_management(thePagesLayer, fld,
table, "Page", "Page2")
arcpy.Delete_management(fOut)
except:
message = "\n*** PYTHON ERRORS *** "; showPyMessage()
message = "Python Traceback Info: " + traceback.format_tb(sys.exc_info()[2])[0]; showPyMessage()

Output example I am using to control how prints will look like:
Note grey part is separate element here. You also have to change text format line in above script.
Second script does printing (export to pdf, using DDP name), assumes DDP layer name = Pages (the one with attachmet) and there is text element called TABLE in the layout
import arcpy, traceback, os, sys
from arcpy import env
env.overwriteoutput=True
folder=arcpy.GetParameterAsText(0)
aTable=arcpy.GetParameterAsText(1)
#Reference MXD and layers
try:
def showPyMessage():
arcpy.AddMessage(str(time.ctime()) + " - " + message)
def isLayerExist (mxd,lName):
layers = arcpy.mapping.ListLayers(mxd,lName)
if len(layers)==0:
raise NameError,'\n'+lName + " layer not found. Exiting.."+'\n'
result=layers[0]
return result
mxd = arcpy.mapping.MapDocument("CURRENT")
thePagesLayer = isLayerExist(mxd,"Pages")
ddp = mxd.dataDrivenPages
fld = ddp.pageNameField.name
diction={}
both=arcpy.da.TableToNumPyArray(thePagesLayer, (fld,"OBJECTID"))
for row in both:
diction[row[0]]=row[1]
Page_Names=[row[0] for row in both]
del both
#Reference page layout elements
for elm in arcpy.mapping.ListLayoutElements(mxd):
if elm.name == "TABLE":
tableTxt = elm
x=elm.elementPositionX
y=elm.elementPositionY
for pageID in range(1,ddp.pageCount+1):
## for pageID in range(1,3):
ddp.currentPageID = pageID
baseName=Page_Names[pageID-1]
OID=diction[baseName]
query='REL_OBJECTID = %s' %str(int(OID))
with arcpy.da.SearchCursor(aTable,'DATA',query) as cursor:
for row in cursor:
binaryRep = row[0]
textB=binaryRep.tobytes()
if len(textB)>0:
tableTxt.text = textB
else:
tableTxt.text = " "
tableTxt.elementPositionY=y
arcpy.RefreshActiveView()
ddp.exportToPDF(folder+os.sep + baseName + ".pdf","CURRENT")
arcpy.AddMessage('Exported %i %s' %(pageID,baseName))
except:
message = "\n*** PYTHON ERRORS *** "; showPyMessage()
message = "Python Traceback Info: " + traceback.format_tb(sys.exc_info()[2])[0]; showPyMessage()
message = "Python Error Info: " + str(sys.exc_type)+ ": " + str(sys.exc_value) + "\n"; showPyMessage()
In above example points are labelled by SectionID and table provides perfect reference.
This couple saved me weeks of time...
I am using 2 scripts because formatting is a hard part, so I run first script with only 2 layers - points and pages on a very basic mxd. Second works fine and I run it on the map with multiple layers, symbology sorted etc
This is an upper right corner of one of the output pages:

Aragon deals with the placement of the labels (Maplex is infinitely better if you have it), however to actually create the numeric labels should be quite simple:
[FID]. When you hit "OK" the FID (which is an incremental number) will be copied over to this column and you'll have your numbers.Note - FID starts at 0. So if you want your numbers to start at 1, you'll need to change
[FID]to[FID] + 1in the last stage.Actually strictly speaking that isn't even necessary now I look. If you just go to the "Labels" tab and click on expression, if you enter
[FID] + 1you'll get the same result without having to create a new column.
