How to create a recordset, not connected to database, but I can add new item to it?


i would like to create  a new recordset, but not connecting to any database. I have a list of items which I can only add into the recordset during runtime.

I wrote the below, but was told by the system that "Operation is not allowed when the object is closed" . I tried to open it, but I receive error "The connection cannot be used to perform this operation. It is either closed or invalid in this context"

   Dim country() as string
    country = Split(gCountryFromDB, "|", , vbTextCompare)
    Dim rsCountryM As New ADODB.Recordset
    For i = 0 To UBound(country)
        rsCountryM.AddNew "sCountryCode", country(i)
    Next i

Please help! Thanks!

Hi there you can use this connection.

Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim i As Long

conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Database.mdb;"

sqlstr = "Table"

rs.Open sqlstr, conn, adOpenKeyset, adLockOptimistic

    For i = 0 To UBound(country)
        rs.Fields("sCountryCode")  = UBound(i) .txt

    Next i

Set rs = Nothing
Set conn = Nothing
You have to add fields to the recordset.This simple example will create a recordset and add three items to it,without a database.

' add reference to Microsoft ActiveX Data Objects Library

Dim rstADO As ADODB.Recordset

Private Sub Command1_Click()
Set rstADO = New ADODB.Recordset
With rstADO.Fields
  .Append "MyTextField", adVarChar, 50 'Character field, varchar type max 50 chars
  .Append "MyNumField", adInteger
End With

rstADO.Fields("MyTextField") = "My Text Item 1"
rstADO.Fields("MyNumField") = 1

rstADO.Fields("MyTextField") = "My Text Item 2"
rstADO.Fields("MyNumField") = 2

rstADO.Fields("MyTextField") = "My Text Item 3"
rstADO.Fields("MyNumField") = 3

While Not rstADO.EOF = True
    MsgBox rstADO.Fields("MyTextField")
    MsgBox rstADO.Fields("MyNumField")

Set rstADO = Nothing
End Sub

You need to add fields. See this sample:

Private Sub Command1_Click()
Dim i As Integer
Dim rsCountryM As New ADODB.Recordset

    With rsCountryM
        With .Fields
            .Append "Field1", adVarChar, 50
            .Append "Field2", adVarChar, 50
        End With
        .CursorLocation = adUseClient
        .CursorType = adOpenStatic
        .LockType = adLockBatchOptimistic
    End With
    For i = 0 To 10
        With rsCountryM
            .Fields("Field1").Value = "Line " & CStr(i)
            .Fields("Field2").Value = "Value " & CStr(i)
        End With
    MsgBox rsCountryM.RecordCount
End Sub
