Visual Basic连接到MS Access：按钮和文本框不起作用

Question

我正在Visual Studio中创建一个接受数据并将其存储到MS Access的项目。然后提供一个按钮来显示另一个表单，该表单具有来自数据库的数据的数据网格视图，并将数据表示为图形形式。成功连接数据库和软件后，按钮将停止工作，无法在文本框中输入数据，也无法关闭程序。这是我的GUI：

和我的代码：

Public Class main

Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'TODO: This line of code loads data into the '_QualiPool_1_1DataSet.Temperature' table. You can move, or remove it, as needed.
    Me.TemperatureTableAdapter.Fill(Me._QualiPool_1_1DataSet.Temperature)

End Sub

Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
    TemperatureBindingSource.AddNew()
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    TemperatureTableAdapter.Update(_QualiPool_1_1DataSet.Temperature)
    TemperatureBindingSource.EndEdit()
    MessageBox.Show("Data has been saved")
End Sub

Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click
    Database.Show()
End Sub
End Class
