Calculate two attribute fields within the same shp file, populate new field

Discussion created by meg36 on May 18, 2011
Dear All,

I need to perform a calculation on two attributes within the same shape file {field [a] + field [b], enter into field [c] - basically, coding in VB 6.0 what the fieldcalculator would do. Does anyone know how to do this please? Or can someone send me a code for adding together the attributes from 2 separate shp files?

Many thanks,
