create a dataset

1 John Michigan
2 Karl California
3 Meg Iowa

I have a list box with the items shown above..
Can some one tell me how to create a dataset table.

Thanx!

I'll assume you want the number to be your primary key:-

VB Code:

'declare dataset, datable and datacolumn
dim ds as dataset
dim dt as new datatable("SomeNames")
dim dc as datacolumn
 
'create 2 datacolumns and add to the datable
dc = new datacolumn
dc.DataType = System.Type.GetType("System.Int32")
dc.ColumnName = "id"
dc.Unique = True
dc.AutoIncrement = true
dt.Columns.Add(dc)
dc = new datacolumn
dc.DataType = System.Type.GetType("System.String")
dc.ColumnName = "Name"
dt.Columns.Add(dc)
 
'set the id column as the primary key
Dim PrimaryKeyColumns(0) As DataColumn
PrimaryKeyColumns(0)= dt.Columns("id")
dt.PrimaryKey = PrimaryKeyColumns
 
'add the datable to the dataset
ds = new dataset
ds.tables.add("SomeNames")
 
'now add some rows
dim dr as datarow = dt.rows.newrow
dr("Name") = "John Michigan"
dt.rows.add(dr)

You can of course create 2 string columns for first and second name if you wish. As usual I leeched this code from the .net docs. Always worth checking it out.

Thanx a bunch!!!
