初始化字符串的格式不符合從索引0開始的規範 - 帶有Microsoft Access的Visual Basic.NET

Question

嘗試運行我的程序時遇到此問題。這些代碼去這樣

Private Sub mainmenu_Load(sender As Object, e As EventArgs) Handles MyBase.Load 
    conString = "C:\Users\Nur Amira\Documents\SEM 5\SDP\sdddd\sdddd\Database1.mdb" 
    Dim con As New OleDbConnection(conString) 
    con.Open() 
    Sql = "select * From Login" 


    Dim da As New OleDbDataAdapter(Sql, con) 
    da.Fill(ds, "Role") 
    totrec = ds.Tables("Role").Rows.Count - 1 

    For i = 0 To totrec 
     cmboxpos.Items.Add(((ds.Tables("Role").Rows(i).Item(2).ToString))) 
    Next 
End Sub 

它會彈出一個窗口框將錯誤通知的標題與

Dim con As New OleDbConnection(conString) 

突出。有任何解決這個問題的方法嗎？

連接字符串不僅僅是文件路徑/名稱。示例：

Connection Strings
