Private Methods

Method Description
AddIntToDict ( Dictionary dict, int line ) : void

Helper function for ImportDesiredVariables
CheckForDuplicates ( DataTable dt ) : string
CheckForMOEDuplicates ( DataTable dt ) : string

Generates an error if a generated column conflicts with another generated column, or a real column.
CheckForMaxColumns ( DataTable dt ) : string

To keep things simple, lets say the max # of columns in a shapefile is 256, so 100 vars * 2 (var + error margin) == 200 columns, we don't need to test for room for the extra "AREA/PERIMETER/CENTROID" mode, unless we change our max from 100 columns. The extra room is to try and avoid running out of memory during an export.
CheckForMinColumns ( DataTable dt ) : string
CheckForReserved ( DataTable dt ) : string
IfSetAddIntToDict ( HashSet set, Dictionary dict, int line ) : void
