Question

我试图让我的程序使用事件处理程序和tableadapter向数据库添加一行。我可以成功地向数据库添加一行，但是当我点击＆＃34; btnRefresh＆＃34;按钮。这是事件处理程序的代码。

Private Sub btnRefresh_Click(sender As Object, e As EventArgs) Handles btnRefresh.Click
    Try
        Validate()
        CarsBindingSource.EndEdit()
        CarsTableAdapter.Update(Me.ABVDataSet.Cars)
        MsgBox("Refreshed Successfully")
    Catch ex As Exception
        MsgBox("Update failed")
    End Try
End Sub

Answer 1

Private Sub btnRefresh_Click(sender As Object, e As EventArgs) Handles btnRefresh.Click Try Validate() CarsBindingSource.EndEdit() CarsTableAdapter.Update(ABVDataSet,"table_name") MsgBox("Refreshed Successfully") Catch ex As Exception MsgBox("Update failed") End Try End Sub
