ASP VBScript - Running from a Windows Scheduled Task
- Looks like memory is not released.
For your own testing look at:
Process name: dllhost.exe
- Looks like at some point the ASP page will no longer run. To prove
that I had a batch file that logged to a log file when it was run which
launched an ASP web page that logged to a separate log file. I
scheduled a task to run the batch file every 5 min for 1 hour. The ASP
logged for only 30 min and the batch file logged for the full 1 hour.
- When launching a browser from a batch file via a Windows Scheduled Task
the browser will never unload so you must tell the Scheduled Task to stop
the task prior to restarting the task.
Ex: So if running every 5 min have the task stopped after 4 min etc...
- Create an ASP web page that will complete your task.
- Create a batch file that will launch IE and then run an ASP web page.
- Run the batch file from a Windows Scheduled Task
Example ASP page:
- If you have downloaded the zip file of all ASP examples see:

Error window title: SysFader: iexplore.exe - Application Error
The instruction at 0x0138ac36 referenced memory at "0x00000000". The
memory could not be "read".
For XP Professional my Fix:
Schedule the task to run under "administrator".
Information in the Event Viewer (Application):
Windows saved user THOMASMA9300\<user_logonid> registry while an application or
service was still using the registry during log off. The memory used by the
user's registry has not been freed. The registry will be unloaded when it is no
longer in use.
This is often caused by services running as a user account, try configuring
the services to run in either the LocalService or NetworkService account.
