Answer 1

请注意您是如何在您的bindingdata方法中进行查询的 - 在您创建 之后OleDbCommand，您调用Parameters.AddWithValue()以使用数据填充查询。对方法中的插入命令执行相同的操作add：

isi = "INSERT INTO tblkelahiran (no_kk,nm_kk, ... , nm_saksi2) values (@no_kk,@nm_kk, ... , @nm_saksi2)"
perintah = New OleDbCommand(iki, konekOLEDB)
With perintah.Parameters
    .AddWithValue("@no_kk", txtnokk.Text)
    .AddWithValue("@nm_kk", txtnamakeluarga.Text)
    '...
    .AddWithValue("@nm_saksi2", txtnama6.Text)
End With
perintah.ExecuteNonQuery()

这不会解决问题。但是现在您可以将每个AddWithValue调用更改为一个已知值，一次一个，直到问题消失：

.AddWithValue("@no_kk", "txtnokk")

.AddWithValue("@nm_kk", "txtnamakeluarga")

等等。当您不再收到错误时，您更改的最后一项就是导致问题的项。
