You seem to have posted in the wrong group...but here's some code that
inserts 10 rows to a sample datatable to give you an idea.


Dim sampletable As DataTable = New DataTable("Sample")
Dim Row1 As DataRow
Dim Col1 As DataColumn = New DataColumn("col1")
Dim i As Integer

sampletable.Columns.Add(Col1)
For i = 1 To 10
Row1 = sampletable.NewRow
Row1("col1") = i
sampletable.Rows.Add(Row1)
Next
MsgBox(sampletable.Rows.Count)
