unable to "setValue" on a field

Hi,

I'm probably overlooking something obvious, but i'm unable to set a value on a field of a feature class. Here is a short example to show what I am doing.

import arcpy
from arcpy import env

env.workspace = r"X:\temp"

fc = "temp.shp"


desc = arcpy.Describe( fc )

print 'Fields: '
for field in desc.fields:
    print 'Name: ', field.name, 'Type: ', field.type, 'Length: ', repr(field.length)
    

rows = arcpy.SearchCursor( fc )

for row in rows:
    row.setValue("S_T_R", "test")

Here is the output:

Fields:
Name: FID Type: OID Length: 4
Name: Shape Type: Geometry Length: 0
Name: TOWNSHIP_N Type: Double Length: 11
Name: TOWNSHIP_D Type: String Length: 1
Name: RANGE_NUM Type: Double Length: 11
Name: RANGE_DIR Type: String Length: 1
Name: RECORD_NUM Type: String Length: 3
Name: SECTION Type: Double Length: 11
Name: ID_FIELD Type: String Length: 9
Name: S_T_R Type: String Length: 12

Traceback (most recent call last):
File "C:/code/scripts/GIS/addS_T_R.py", line 20, in <module>
row.setValue("S_T_R", "test")
File "C:\Program Files\ArcGIS\Desktop10.0\arcpy\arcpy\arcobjects\arcobjects.py", line 940, in setValue
return convertArcObjectToPythonObject(self._arc_object.SetValue(*gp_fixargs(args)))
RuntimeError: ERROR 999999: Error executing function.

Thanks for any pointers.

Dustin

setValue only works with insertcursor or updatecursors, check the help

Thank you! I knew I was overlooking something obvious...I looked at this help page multiple times, but overlooked the different cursor types!
