MS Access數據庫不從Visual Basic輸入數據

Question

我目前在將數據從Visual Basic導出到Ms Access文件時遇到問題。 在執行表單時，出現以下錯誤。.“更新通過具有修改后的行的DataRow集合時，更新需要有效的UpdateCommand。它無法將數據導出到Ms Access。

該表格的目的是當用戶輸入新的用戶名和密碼時，將其導出到Ms Access數據庫並保存。 我有另一種形式，可以從數據庫正確導入數據。

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
