Question

我一直在尝试将 Microsoft 访问数据库文件连接到我的 Visual Basic 应用程序。当我尝试运行应用程序时出现错误：“Microsoft.ACE.OLEDB.12.0' 提供程序未在本地计算机上注册”我使用的是 Microsoft Visual Basic 2012。

 Public Class purchases

    Private Sub Purchases_fileBindingNavigatorSaveItem_Click(sender As Object, e As EventArgs) Handles Purchases_fileBindingNavigatorSaveItem.Click
        Me.Validate()
        Me.Purchases_fileBindingSource.EndEdit()
        Me.TableAdapterManager.UpdateAll(Me.TNJ_Retail_Management_SystemDataSet)

    End Sub

    Private Sub purchases_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'TNJ_Retail_Management_SystemDataSet.Purchases_file' table. You can move, or remove it, as needed.
        Me.Purchases_fileTableAdapter.Fill(Me.TNJ_Retail_Management_SystemDataSet.Purchases_file)

    End Sub
End Class

Was able to correct the error simply by downloading Microsoft Access Database Engine and installing it in my PC. I then opened my project, rebuild it and run. Gave expected results. Click here to open site to download the Microsoft Access Database Engine
