找不到可安装的 ISAM Visual Studio 2012

Question

我在申请学校时遇到了一些困难。我正在尝试调用我创建的数据库以将 ID 代码加载到 Visual Basic 中的组合框。我使用的是 windows 8.1 和 office 2013 的 64 位版本。还有 visual studio ultimate 2012。我已经安装了 2010 访问数据库引擎。我将首先向您展示我的代码。

Imports System.Data
Imports System.Data.OleDb

Public Class VDObjects

    Public Shared strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Arcanum\Documents\VincentMcMullen\VandelayDB.accdb;Persist Secruity Info=False;"

    Public Class Department

        'Department ID
        Private DeptIDValue As String
        Public Property DeptID() As String
            Get
                Return DeptIDValue
            End Get

            Set(ByVal value As String)
                DeptIDValue = value
            End Set

        End Property

        'Department Description
        Private DeptDescrValue As String
        Public Property DeptDescr() As String
            Get
                Return DeptDescrValue
            End Get

            Set(ByVal value As String)
                DeptDescrValue = value
            End Set

        End Property


        'populate a drop down box with all available users
        Public Shared Sub PopulateDropdown(ByRef cbSelect As ComboBox)
            Dim con As New OleDb.OleDbConnection
            con.ConnectionString = strConn

            'SQL Query to get department IDs
            Dim qry As String = "SELECT DepartmentID FROM tblDepartments "
            Dim cmd As New OleDb.OleDbCommand(qry, con)

            Try
                'first clear the current entries
                cbSelect.Items.Clear()

                'run and add query and add the values
                con.Open()
                Dim reader As OleDbDataReader = cmd.ExecuteReader()

                While reader.Read()
                    cbSelect.Items.Add(reader.GetString(0))
                End While

            Catch ex As Exception
                MsgBox(ex.ToString)
            Finally
                con.Close()
            End Try

        End Sub



    End Class





End Class

它会在读取"con.Open()" 的行上失败并立即去捕获。我会告诉我 "cannot find an installable ISAM." 我已经重新安装了 office，并根据微软支持建议验证了它们都是 64 位版本。任何见解将不胜感激。

谢谢

Answer 1

您的连接字符串中有错字（"Secruity"）：

Persist Secruity Info=False;

...应该是...

Persist Security Info=False;

...虽然您真的不需要包含该参数，因为 False 是默认值。
