老师，上面是复制数据的按钮代码。下面是表事件代码。
Dim s As Integer =Tables("数据库更新").Rows.Count - 1
If s > 0 Then
If Forms("股piao数据明细").opened
Dim sjbrq As WinForm.TextBox = e.Form.Controls("数据包日期")
sjbrq.value=Tables("数据库更新").rows(s)("日期")
End If
End If
这两个代码好像有冲突。我在复制数据时报错。
.NET Framework 版本：2.0.50727.3655
Foxtable 版本：2014.11.11.1
错误所在事件：表，数据库更新，DataColChanged
详细错误信息：
Exception has been thrown by the target of an invocation.
Object reference not set to an instance of an object.
