[resolved] service with timer - timer event not firing

[jpritchard]

hi,

Ii wonder if anybody has any good experience when designing a service using c#.

I need to perform some tasks on a server. its to regualry do some checking and other work and I dont really want a long running console app or it to be running in a user context, hence thought that writing it as a windows service was the way to go...

I started checking out .net services with some testcode..

I have done this many times before in std vb using the svrany tool from the NT-RK and have had little problem inthe past...

at the moment I have got the following code before

i'm installing it using the installutil.exe utility ("installutil <myservicenname>") and starting the service with "net start <myservicenname>".

the service installs and starts ok - it logs a message in a file at start and stop time.

what isn't happening is, I cannot seem to make the timer event fire and run my code! - i have copied my timer functionality to a standard .net form app and it works ok.

I wonder if my design is wrong or am i missing some concept somewhere? etc.... at the begining the timer is loaded in the InitializeComponent() section and started in the OnStart() section.

cannot understand why I done get a new file in my file evey secord (I havent got the file open in notepad or something silly like that)

heres my code - any thoughts greatly appreciated

cheers, AJP
