範例
下列範例顯示如何初始化 SqlCeRemoteDataAccess 物件的新執行個體。
' Connection String to the SQL Server
'
Dim rdaOleDbConnectString As String = "Data Source=MySqlServer;Initial Catalog=AdventureWorks; " & _
"User Id=username;Password = <password>"
' Initialize RDA Object
'
Dim rda As SqlCeRemoteDataAccess = Nothing
Try
' Try the Pull Operation
'
rda = New SqlCeRemoteDataAccess( _
"https://www.adventure-works.com/sqlmobile/sqlcesa35.dll", _
"MyLogin", _
"<password>", _
"Data Source=MyDatabase.sdf")
rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString, _
RdaTrackOption.TrackingOnWithIndexes, "ErrorTable")
' or, try one of these overloads:
' rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString, _
' RdaTrackOption.TrackingOnWithIndexes)
'
' rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString)
Catch
' Handle errors here
'
Finally
' Dispose of the RDA object
'
rda.Dispose()
End Try
