问题描述

我在使用Windows任务调度程序(或AT或SCHTASKS)时遇到问题

无人值守运行VB.NET程序。


我'能够将它减少到一些仍然失败的非常简单的代码


我的程序有一个Sub Main类似的东西


Sub Main()


MainForm.showdialog


结束子


在MainForm中New()执行,但MainFormLoad事件中的代码

不是。然后我在事件日志中得到一个System.InvalidOperationException



为什么这么难,当VB6可以做到这一点没问题?


谢谢


Rob

I''m having problems using Windows Task scheduler (or AT or SCHTASKS) to
run a VB.NET program unattended.

I''m able to reduce it to some really simple code that still fails

My program has a Sub Main something like

Sub Main()

MainForm.showdialog

End Sub

In MainForm the New() does execute, but code in the MainFormLoad event
doesn''t. I then get a System.InvalidOperationException in the Eventlog
for that machine.

Why is this so hard, when VB6 can do this no problem?

Thanks

Rob

推荐答案

关于哪些陈述失败了?


IMO它更可能是由执行上下文引起的,而不是由VB6与VB.NET问题引起的。例如,尝试在服务帐户下使用

打印机的应用程序可能会失败,因为在这种情况下用户配置文件

未加载且没有默认打印机可用...

news: 5r ************* @ mid.individual.net ...
On which statements does it fail ?

IMO it is caused more likely by the execution context rather than by some
VB6 vs VB.NET issue. For example an application that would try to use the
printer under a service account could fail as in this case the user profile
is not loaded and sop there are no default printers available...

感谢您的回复,但是我的任何代码都没有失败。


我添加了一些日志记录:


1.登录Sub Main( )没关系


2.登录表单''s New()是好的


3.登录FormLoad事件永远不会得到执行。


在我看来,如果

代码要从调度程序运行,我就不能显示一个表单(使用.ShowDialog) ,但我不能成为唯一有这个问题的人。实际上,我知道我不是因为我在谷歌时获得了一些

点击,但只有少数,而且从未有过解决方法。


谢谢

Thanks for the reply, but it doesn''t fail on any of my code.

I added some logging:

1. Logging in the Sub Main() is OK

2. Logging in the form''s New() is OK

3. Logging in the FormLoad event never gets executed.

It seems to me that I just can''t show a form (using .ShowDialog) if the
code is to run from a scheduler, but I can''t be the only person out
there with this problem. Well actually I know I''m not as I do get some
hits when I Google, but only a few, and never with a workaround.

Thanks

Rob

我试了一下它没有错误。当任务

启动时你是否登录?如果你不是,那是不可能的。你必须用UI写一个服务



Armin


I tried it and it works without an error. Are you logged-in when the task
starts? If you are not, it is not possible. You''d have to write a service
w/o a UI.
