Hello @Luis

You can try something like (in [VB.NET](http://VB.NET)):

```
    Dim utils As New Utils()

    Dim cat As ShapefileCategory = sf.Categories.Add("Cat459")
    cat.ValueType = tkCategoryValue.cvExpression
    cat.Expression = "[Categoria] = 459"
    Dim options As ShapeDrawingOptions = cat.DrawingOptions
    With options
        .Visible = True
        .LineColor = utils.ColorByName(tkMapColor.Blue)
        .LineWidth = 2
    End With

    cat As ShapefileCategory = sf.Categories.Add("Cat554")
    cat.ValueType = tkCategoryValue.cvExpression
    cat.Expression = "[Categoria] = 554"
    options As ShapeDrawingOptions = cat.DrawingOptions
    With options
        .Visible = True
        .LineColor = utils.ColorByName(tkMapColor.Red)
        .LineWidth = 2
    End With

    sf.Categories.ApplyExpressions()

```

Regards,  
Jerry.
