找不到可安裝的ISAM

Question

我需要幫助。我編譯我的系統在vb.net

這裏後遇到的錯誤是我的代碼

Dim dtStudentPermit As DataTable 
Dim dtExcelData As DataTable 
Public constring As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Exam.accdb;Jet System.OleDb.Database Password = graduation" 
Public connect As New OleDbConnection 

Private Sub Identification_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
    connect.ConnectionString = constring 

    If connect.State = ConnectionState.Closed Then 
     connect.Open() <------< 'Error: Could not find installable ISAM. 
     MsgBox("Connection is Open") 
    Else 
     MsgBox("Connection is Closed") 

    End If 
End Sub 

Answer 1

這應該是：

... ";Jet OLEDB:Database Password = graduation" 

見http://www.connectionstrings.com/ace-oledb-12-0/with-database-password/

在大多數情況下，如果你得到'無法找到可安裝的ISAM'，你可以懷疑你的連接字符串。

DAO的訪問速度通常比ADO快得多。
