Question
How do I save a DBASE dbf file using ADO.NET
I have very successfully used VB6 and ADO to read/write to DBF files in the past. But we have converted to VB.Net and I am stuck with a problem on SAVING the dbf files. I can read/append/edit the ADO.Net datatable, but I cannot save it to the file when I'm done. Below are the details of the code I'm working with:
Public Sub DoIt()
DIM ds as new dataset
Dim oConnWireDbf As New OleDb.OleDbConnection(Conn
oConnWireDbf.Open()
'
sSql = "SELECT * FROM Wire"
Dim da As New OleDb.OleDbDataAdapter(sSq
da.Fill(ds, "rsLiveWireDBF")
'
dtLiveWireDBF = ds.Tables("rsLiveWireDBF")
For xRows = 0 To dtLiveWireDBF.Rows.Count - 1
'Do some things to the datatable
Next xRows
'
'Everything works down to here. From the command window I can print the records and fields that i added/edited
'so all I need to do now is save it.
'------------------------
'I have tried these (individually and collectively to no avail)
dtLiveWireDBF.AcceptChange
ds.Tables("rsLiveWireDBF")
da.Update(ds, "rsLiveWireDBF")
'------------------------
oConnWireDbf.Close()
oConnWireDbf = Nothing
End Sub
Public Function ConnWireDbf() As String
Dim r As String
'The old driver I used in with VB6 and ADO
r = "Driver={Microsoft Visual FoxPro Driver};UID=;PWD=;SourceDB
r = r & "BackgroundFetch=No;Collat
'
The new driver I need with VB.NET and ADO.NET
r = "Provider=Microsoft.Jet.OL
r = r & "User ID=Admin;Password= """""
Return r
End Function
