Question

我目前在将数据从Visual Basic导出到Ms Access文件时遇到问题。执行我的表单时，我收到以下错误。＆＃34;更新需要一个有效的UpdateCommand传递带修改行的DataRow集合。它无法将数据导出到Ms Access。

此表单的目的是当用户写入新的用户名和密码时，将其导出到Ms Access数据库并保存。我有另一种形式，正确地从数据库导入数据。

Public Class LoginTestV2

Private Sub LoginTestV2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    'TODO: This line of code loads data into the 'DataDataSet.TblUserAccount' table. You can move, or remove it, as needed.
    Me.TblUserAccountTableAdapter.Fill(Me.DataDataSet.TblUserAccount)


End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles btnCreateAccount.Click
    Me.TblUserAccountTableAdapter.Fill(Me.DataDataSet.TblUserAccount)

    On Error GoTo SaveErr
    TblUserAccountBindingSource.EndEdit()
    TblUserAccountTableAdapter.Update(DataDataSet.TblUserAccount)
    MsgBox("You have created your account! You're on your way to start Recycling!")
SaveErr:
    Exit Sub
End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles btnClose.Click
    Me.Close()
End Sub
End Class
