New Post: Creating Legend in VB.net

Well, let me try...

This is the sample of data in the shapefile's DBF:

IDPROV  NAMEPROV
11      ACEH
12      NORTH SUMATERA
13      WEST SUMATERA
31      JAKARTA
32      WEST JAVA
51      BALI

In this part:

Dim index As Integer = sf.Table.FieldIndexByName("IDPROV")
sf.Categories.Generate(index, MapWinGIS.tkClassificationType.ctEqualIntervals, NumericUpDown1.Value)

the variable "index" means the index of the field in the dbf that has the name "IDPROV", doesn't it?
Then, I have to compare this IDPROV value with the other IDPROV in the MDB:

IDPROV  SEXRATIO
11      100.026
12      99.586
13      98.482
31      102.756
32      103.459
51      101.601

so that I can retrieve the values of SEXRATIO, right?
But I have no idea how to use the SEXRATIO field to create the shapefile categories.
Could you please show me how to do it, Pein?
Thank you...
