Count number of features in FeatureClasses

[Andreas_ForøTollefsen]

Hi all.

What i want to do is to create a list of the number of features in each of my featureclasses.

I have already created a list of all the featureclasses in the workspace.

Now i need to iterate through all of these and count the number of features in each featureclass.

import arcgisscripting
import os
gp = arcgisscripting.create(9.3)

gp.Workspace = "H:\\geodata\\"

print "Generating list of featureclasses in" " " + gp.Workspace
fcList = gp.ListFeatureClasses()

for fc in fcList:
    print fc
   

Anyone have a suggestion? I assume i need to use the cursor object?

You have no idea how much time I wasted because of this problem... wow. THANK YOU SO MUCH! I thought I was going insane... I had imported the 9.3 geoprocessor on a new version of the script, and I could not figure out why it wasn't working.

Greetings,

Is there a way to get all the featureclasses in a worksapce through vb.net code?

please advise.....
