Schedule Task at window 2000?

Hi All,

I have used Visual Basic 6.0 to develop a window application before. Now I would like to schedule this application to run at 1:00am everyday.

I know I can do this by adding a schedule task by using "Scheduled Tasks" at control panel.

But I found the application can work only after logging the OS.
I want the application can be run properly if I have power on my PC without log in.

How can I solve this problem?

If I run my application as a service, can this solve my problem?
Can a service be scheduled to run periodically?

Please advice. Thanks!

Idealy the program would be designed to run as a service, but not all of them are. You have to be carefull with this however. Not all programs run well as a service - VB apps for example are not recommended to be run as a service.
There is a utility called srvany that will probably work for you. It is available as a download at Microsofts web site

Your application should normally be running even if you are not logged in. A mistake often done by programmers is that resources (mapped drives, printers, ...) are not available when not logged in.

Start by creating an application that does nothing and schedule it. You should see that the application will be launched. Then add your code to this application with a lot of tracing (wrtiting to a .log file on the C: drive) to know exactly where the application is going and where it is stopping.

I know I can use Scheduled Task to run an exe file periodically. How about a service?

Thanks!

A service is yet another thing and have more  limits! Also, Windows Services should be written in VB.Net to be easier.

Dear emoreau,

My application needs to use a network drive.
Can I map a network drive without log in the OS?

Further, please advise whether a service can be scheduled or not?
Thanks!

Could you give me the source code to use URN to map a network drive?

Dear emoreau,

The most important question:

A service at window 2000 can be scheduled to run at a specified
time or not?

Thanks!

Not a service. Only an application.
