摘要: Private Sub Command5_Click() Me.Child0.SetFocus DoCmd.RunCommand acCmdSelectAllRecords DoCmd.RunCommand acCmdCopy Dim obj As Object Set obj = CreateObject(excel.application) obj.workbooks.Add o ...

Private Sub Command5_Click()
Me.Child0.SetFocus
DoCmd.RunCommand acCmdSelectAllRecords
DoCmd.RunCommand acCmdCopy
Dim obj As Object
Set obj = CreateObject("excel.application")
obj.workbooks.Add
obj.Visible = True
SendKeys "^v"
obj.Visible = True
End Sub

上面这段语句如何让数据复制到Excel表格之后将剪切板清空
请各位老师帮帮忙，谢谢
问题补充：我在执行上述语句之后（导出2万多条数据至EXCEL表），点击该主窗体的退出命令后好长时间才关闭主窗体，不知道为什么，是剪切板有很多数据的原因吗？应该如何改变这种情况呢？

有老师说是我导出后没有释放，我不知道应该处理，请大家看看附件，谢谢

或者不使用这种语句导出数据，我要是直接使用宏导出数据，发现导出的是空白；如果这个子窗体的记录集在窗体加载时赋值，用宏可以导出数据。关闭主窗体也很快，但是用这种语句导出数据关闭主窗体就很慢，郁闷啊，请高手赐教...
