listview question

SA
My listview has 3 columns i.e. name, populaiton, and country code in order.
I use following code to insert data into listview and I find that I can't
assign which subitem related to related field. e.g. assign population to
column2. In vb 6, I can do it by "subitems(i). How about in .net? thx.

i = 0
While MyDataAdapter.Read
ListView1.Items.Add("")
ListView1.Items(i).Text = CStr(MyDataAdapter("name"))
ListView1.Items(i).SubItems.Add(MyDataAdapter("pop ulation"))
ListView1.Items(i).SubItems.Add(MyDataAdapter("Cou ntryCode"))
i = i + 1
End While

Hi,

Dim strConn As String
Dim conn As SqlConnection
Dim drCustomer As SqlDataReader
Dim cmd As SqlCommand

strConn = "Server = " + Environment.MachineName + ";"
strConn += "Database = NorthWind;"
strConn += "Integrated Security = SSPI;"

conn = New SqlConnection(strConn)
cmd = New SqlCommand("Select * from Customers", conn)
conn.Open()

Dim chID As New ColumnHeader
chID.Text = "Customer ID"
chID.Width = 70

Dim chCompany As New ColumnHeader
chCompany.Text = "Company Name"
chCompany.Width = 200

Dim chContact As New ColumnHeader
chContact.Text = "Contact Name"
chContact.Width = 150

ListView1.Columns.Add(chID)
ListView1.Columns.Add(chCompany)
ListView1.Columns.Add(chContact)

ListView1.View = View.Details

drCustomer = cmd.ExecuteReader
Do While drCustomer.Read
Dim lvi As New
ListViewItem(drCustomer.Item("CustomerID").ToStrin g)
lvi.SubItems.Add(drCustomer.Item("CompanyName").To String)
lvi.SubItems.Add(drCustomer.Item("ContactName").To String)
ListView1.Items.Add(lvi)
Loop
conn.Close()

Firstly, thx but the order must be same in your code.
example, the column order is CustId, CompanyName, and Contact
During add record, I set a wrong order and the result is that contact name
data is added to column 2 i.e. Company Name.

ListViewItem(drCustomer.Item("CustomerID").ToStrin g)
lvi.SubItems.Add(drCustomer.Item("ContactName").To String)
lvi.SubItems.Add(drCustomer.Item("CompanyName").To String)
ListView1.Items.Add(lvi)

Is any mistake in my view? thx.
