Windows任务计划程序无法重新启动 [英] windows task scheduler fails to restart
问题描述
我构建了一个C＃应用程序，它扫描文件夹并弹出一个表格，如果
文件夹中有任何文件。我已将此计划为
任务，使用Windows任务计划程序每1分钟重复一次。但是，b $ b发生的是，如果该应用程序正在运行，任务调度程序
无法启动相同的exe。否则它会启动它。有人对这个问题有任何建议吗？
谢谢，
CKG
（PS：启动时我的表单应用程序，扫描运行的同一个
程序的任何实例并将其杀死。当我尝试运行
$ b $时一切正常b手动多次执行！）
尝试将其写为服务。
使用计时器勾选检查目录并跟踪您的
表格是否打开。

怎么可能应用程序运行超过一分钟是你必须回答的
问题。如果您安排任务每分钟运行一次，那么您需要确保只有一个实例在运行。

Hi,
I built a C# application that scans a folder and pops up a form if
there are any files present in the folder. I have scheduled this as a
task to repeat every 1 min using the windows task scheduler. But what
happens is that if that application is running, the task scheduler
fails to start the same exe. Otherwise it starts it. Do any one have
any suggestions on this problem?
Thanks,
CKG
(P.S: My form app when started, scans for any instance of the same
program running and kills it. It all works fine when i try to run the
exe many times manually!)
Try writing it as a service.
Use a timer tick to check the directory and keep track of whether your
form is open or not.

Or you could use the filesystem monitoring classes to check if there are
files in the folder.

How is it possible that the applications runs for more than a minute is the
question you have to answer. If you schedule a task to run every minute, you
have to make sure there is only one instance running.
