有段代码不明白什么意思，请指教！
Private Sub Loadcontrol(lPage As Long)

Dim adoPrimaryRS As ADODB.Recordset

Dim lPageCount As Long

Dim nPageSize As Integer

Dim lCount As Long



'每页显示的纪录

nPageSize = 30

Set adoPrimaryRS = New ADODB.Recordset

adoPrimaryRS.Open "select * from ask ", conn, adOpenStatic, adLockOptimistic



adoPrimaryRS.PageSize = nPageSize

'页数

lPageCount = adoPrimaryRS.PageCount

If lCurrentPage > lPageCount Then

lCurrentPage = lPageCount

End If



adoPrimaryRS.AbsolutePage = lCurrentPage

'定义另一个记录集

Dim objrs As New ADODB.Recordset

'添加字段名称

For lCount = 0 To adoPrimaryRS.Fields.Count - 1

objrs.Fields.Append adoPrimaryRS.Fields(lCount).Name, adVarChar, adoPrimaryRS.Fields(lCount).DefinedSize

Next

'打开记录集

objrs.Open

'将指定记录数循环添加到objrs中


For lCount = 1 To nPageSize
If adoPrimaryRS.EOF Or adoPrimaryRS.BOF Then
Exit For
Else
objrs.AddNew

objrs!姓名 = adoPrimaryRS!姓名

objrs!密码 = adoPrimaryRS!密码

adoPrimaryRS.MoveNext
End If
Next

'绑定

Set DataGrid1.DataSource = objrs



'在文本框显示页数

txtPage = lPage & "/ " & adoPrimaryRS.PageCount

End Sub

以下这段代码是什么意思，
objrs.Fields.Append adoPrimaryRS.Fields(lCount).Name, adVarChar, adoPrimaryRS.Fields(lCount).DefinedSize


[解决办法]
追加字段，名，型，度
