I have a problem where I cannot read (all the time) a file when caught by
the FileSystemWatch er. What I have done to get past this is create an array
of events (when I receive one I add it to the list). I then enable a timer
which will attempt to process the first one in the list.
The timer code is never executed. There is a handles clause on the timer
and using the debugger I have watched the code for the FileSystemWatch er
execute. Code below:
Private Sub FileSystemWatch er1_Created(ByV al sender As Object, ByVal e As
System.IO.FileS ystemEventArgs) Handles FileSystemWatch er1.Created
Dim poWE As New WatcherEvents
poWE.FileName = e.FullPath
poWE.Type = "Create"
maEvents.Add(po WE)
Timer1.Interval = 500
Timer1.Enabled = True
LogChange(e.Ful lPath, "Creating request for ", 102)
End Sub
Private Sub Timer1_Tick(ByV al sender As System.Object, ByVal e As
System.EventArg s) Handles Timer1.Tick
LogChange("", "Enter timer routine ", 997)
If maEvents.Count = 0 Then Exit Sub
Dim poWE As WatcherEvents
......
The FileSystemWatch er1_Created executes and the log event happens. The
timer1_tick does not execute. Even when not debugging I should see the
event log at the beginning of the code for that routine but there is
nothing.

For anyone trying this, it seems that the timer which you can drag to the
service designer does not work. I guess it has to be hosted by a form.
Once again the IDE should stop the developer from doing this if it will not
work.

Lloyd,
You can't use the windows forms timer in a service. You need to use
eiter the System.Threadin g.Timer or the System.Timers.T imer

A clash of doctrine is not a disaster -- it is an opportunity.
Use the timer in the components tool box, not the windows forms timer. This timer has an elapsed event which is the same as the form timer tick event. I had this same problem when I first made services with the tick not firing, and then I stumbled upon the components timer and this fixed it This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I have created a simple service which just copies a fil to a new file
with a new name on certain intervals (the service implements a timer).
I have no problems installing the service and the log-entries I have

However - the actual task is never executed. I catch the execution of
the tick and in the finally-block I write to the eventlog as well. But

I have developed a windows service using the windows service project

few resources. Based on the availability of resources, I use the...

I'm really starting to hate writing services -- or trying to, anyway.
Why do I need to rename my project to the service name?
Why do I need to set the "ServiceName" property to my service name?
Why do I need to set a property within my code to the service name?
Are all these required or am I just doing this for consistency purposes?
