刚刚做.net,问一个很简单的问题:VB连Oracle
为什么说 Connect Timeout=180 是无效的,Connect Timeout是怎么用的

Private m_con As Data.OracleClient.OracleConnection
Private m_ORATrans As Data.OracleClient.OracleTransaction


Public Function dOpen(ByVal sDBSid As String, _
ByVal sDBUserID As String, _
ByVal sDBPass As String) As Boolean
Dim bRet As Boolean

dOpen = False

Try

Dim conStr As String

conStr = "data source= " & sDBSid & "; "
conStr &= "user id= " & sDBUserID & "; "
conStr &= "password= " & sDBPass & "; "
conStr &= "Connect Timeout=180 "


m_con = New Data.OracleClient.OracleConnection(conStr)
m_con.Open()

Catch ex As System.Exception
MsgBox(ex.Message)
''Throw ex
Exit Function
End Try

dOpen = True
End Function

好象是连接超时吧。不用那个也可以
