With All my services I follow the same thing.. which is
1:/ Create a Wrapper object which holds the Guts of the service, Including
the fact that my service code is always 1 or more Threads that instantiate
to do work, such as TCP Listening threads etc. The Wrapper object is really
just a pointer to all the threads.
2. Create a TService object. and a TForm Object..
3. in the program file I test a command line switch, and test for /APP etc..
and for debugging I run the code as an application from the form with a
Start And Stop Button.. (no service code for debugging)
4.. when installing you just run the app with a command line param /install
or /uninstall you dont need to use the service application.
the TService only ever uses Service Start. and Servicestop
procedure TFITv2Service.ServiceStart(Sender: TService; var Started:
Boolean);
begin
// SvcLog.Service := self;
Started := True;
try
StartServer;
HssLog('SERVER START IS COMPLETE',hltNormal);
except
on E:exception do
begin
HssLogExcept(e);
Started := false;
end;
end;
end;
procedure TFITv2Service.ServiceStop(Sender: TService; var Stopped: Boolean);
begin
StopServer;
// SvcLog.Service := nil;
end;
