Hi
Is it possible to do something like that:
1. there is a file located on my website
2. I would like to start a webservice that copies that file each 24 hours to
a backup dir on the website
3. The webservice should be self running (without a client connection)

Until now, I tried the following stuff, but the timer does not run when i
call the method starttimer! I was thinking that the modal variable mVal will
count up on each timer_tick and the stoptimer returns then the amount of
ticks done. But nothing comes back.

Any idea?? Thanks

1. Builded a webservice containing 2 Methods and 1 Timer
Public mVal As Long

<WebMethod()> _

Public Function StartTimer() As String

Timer1.Interval = 1000

Timer1.Start()

StartTimer = CStr(mVal)

End Function

<WebMethod()> _

Public Function StopTimer() As String

Timer1.Stop()

StopTimer = CStr(mVal)

End Function

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Timer1.Tick

mVal = mVal + 1

End Sub

This isn't going to work. What you may want to consider is creating an NT
service to do this - as this is more closely suited to the kinds of things
you would choose service instead of web-service to do.

Web services are stateless - so a call to one method won't carry over to
the next method call. If enough time passes, the thread will time out. In
fact, if you are just creating a normal time on a web service thread, and
then returning, when that thread is reharvested, it's timer will get
orphaned (and eventually croak).

Ok, that was what i assumed.
Because the webserver is not mine, I cant install any software on it.
But if found another solution for doing my (automated) backup.

Thanks anyway.

I could not find a solution for the webservice.After I brought down my
Webspace Provider once :-s, I changed the approach. Instead of having a
continuosly running service on the webserver, I create my backup of the
database when the first user (per day) is login in to the application and
send via email to my workplace. That means, if someone changes data,
automatically the database has been saved once per day.

That replaces my need of the webservice.

Until now, I couldnt figure out the webservice stuff. It's really
complicated, but I think it has to do with the asynchronous call of the
webservice. If I find a solution, I'l post it here of course.

cheers
