--  Exception from HRESULT: 0x800A03EC 报错
老师, 今日不知道怎么回事,我此前编制的程序运行期间不断报错,报错信息如下:

.NET Framework 版本：4.0.30319.42000
Foxtable 版本：2022.8.18.1
错误所在事件：自定义函数,Import_WeeklyMachining_Schedule
详细错误信息：
Exception has been thrown by the target of an invocation.
Exception from HRESULT: 0x800A03EC

检查程序应该没有异常, 程序清单如下:

这种应该是execl文档进程没有全部关闭导致的错误。把vba的代码都放入try里面，保证vba可以正常退出，类似：

Dim App As New MSExcel.Application

try
 Dim Wb As MSExcel.Workbook = App.WorkBooks.open("d:\\test.xls")
……各种vba的处理
    App.Quit
Catch ex As Exception
    MessageBox.Show(ex.message)
    App.Quit
End try
