查询以从主窗体获取子窗体文本值

Question

我尝试从主窗体中的子窗体中的文本框中选择/更新/添加/删除内容。我需要一种方法来访问所述文本框值并与之交互。此代码来自我创建的搜索框。

Private Sub btnSearch_Click()
  Dim SQL As String

  SQL = "SELECT row.product_id, row.product_name, row.impacode, row.product_description, row.explanation, row.mu, row.category_name, row.Quantity " _
    & "FROM row " _
    & "Where product_name LIKE '*" & Me.txtKeywords & "*' " _
    & "OR category_name LIKE '*" & Me.txtKeywords & "*' " _
    & "ORDER BY row.impacode "

   Me.SubCatalog.Form.RecordSource = SQL
   Me.SubCatalog.Form.Requery

End Sub

我想访问数量文本框，获取数字，更新表格或删除它等等...
