This example demonstrates the use of ConnectSession and CreateNamedSession to allow an application to use a session it previously created, but did not save. Copy this code into the definition section of a form. Then press F5.
Sub Form_Load ()
'Declare variables
Dim dfltsess As OraSession
Dim OraSession As OraSession
Dim OraDatabase As OraDatabase
Dim OraDynaset As OraDynaset
'Create the default OraSession Object.
Set dfltsess = CreateObject("OracleInProcServer.XOraSession")
'Try to connect to "ExampleSession". If it does not exist
'an error is generated.
On Error GoTo SetName
Set OraSession = dfltsess.ConnectSession("ExampleSession")
On Error GoTo 0
'Create the OraDatabase Object by opening a connection to Oracle.
Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&)
'Create the OraDynaset Object.
Set OraDynaset = OraDatabase.CreateDynaset("select * from emp", 0&)
'Display or manipulate data here
Exit Sub
SetName:
'The session named "ExampleSession" was not found, so create it.
Set OraSession = dfltsess.CreateNamedSession("ExampleSession")
Resume Next
End Sub
