Hi all,

i have written a Service,now i want to execute another application (for
eg;calc.exe) in the service....how will i perform it??...

i tried using this....

/**************Executing a Process code starts here**************/
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents=false;
proc.StartInfo.FileName="calc";
proc.Start();
/**************Executing a Process code ends here**************/

the above code is not working.......what is the other alternative or is my
approach wrong??...

with regards,
C.C.Chakkaradeep

Chakkaradeep,

What's happening when you run it? Running another program from inside a
service isn't the best idea in the world, especially if it has a UI. If it
has a UI, then you have to let the service interact with the desktop, and
even then, you can't guarantee that there will be a desktop session (there
is none if no one is logged in).

What are you trying to do?

Hi,

My Service is a Multithreaded Server which listens for connections at a
particular port....if any incoming connections come,the server accepts it and
starts an application with the parameter got from remote end by receiving the
informations from Socket....this is what i want to do...i have developed a
Multithreaded Server runnning as service,it is working fine by sending back
replies to clients....but am not able to execute an application....

so what is my next step??...am a newbie to Services...

As I told you before, services should not consider the presence of an
interactive destop, also, they should not spawn processes that have a UI
(he, they should not spawn processes at all).
By default services run in the context of a sandboxed desktop environment,
running a service in the context of the interactive desktop (enabling
"interact with desktop" in the Service properties) should ONLY be considered
for debugging purposes.

Chakkaradeep,

Does the account that the service is running under have the appropriate
permissions? Does the application you are running have a UI, or is it a
console app?

Hi,

My application which to be made run by my Service is a GUI application say
"somename.exe",service has to just make it run....for this also i need to
spawn a thread???

Chakkaradeep,

In this case, you can't do this from a service. How are you going to
control the app from the service if it requires a UI? Also, the interaction
with the desktop is an issue as well. I would find another way to do what
you are doing (perhaps accessing a library that performs the same
functionality).

Hi,

sorry friends,i forgot to add someting IMPORTANT in previous post...i opened
up my Task Manager and found instances of "calc.exe" running which was
started by my Service...but GUI has not shown ???......

this service is important for me becoz am monitoring a port regularly and
have to start my client application as and when i get request....

there is no means that we can start an application using Services???...if
there is,then can anyone tell me code for that or link??

with regards,
C.C.Chakkaradeep

something wasn't very clear.

*** No, you can't, just run this as a normal desktop application, just start
it from a logon script if you need to have it running all the time there is
a user logged-on.

One of these days I'll have to go through and test this so I can stop
talking theory, but for now here is what I have heard and believe will
work "in theory:"

You should be able to go into the service mmc snap-in and set the
properties of the service and set it to allow the service to interact
with the desktop. You'll obviously want to test this to see if it works
but I think it is sound, however as others have mentioned this setting
will only work (if at all) if someone is actively logged on to the system.

If you don't mind some design advice, I would recommend that you split
this into two different applications. One a service that listens for
connections and another that gets started when a user logs on to the
desktop. The startup application would register with the service to be
passed notification that the "calc.exe" application should be started
and then the startup application would run "calc.exe". This would allow
you to have the functionality that you are looking for, not be worried
about whether or not a service can run something on the desktop, and
allow remote workstations to register and receive the same kinds of
messages/application startups as the local system. Just a thought.

Have A Better One!

P.S. Please let me/us know if you decide to try the interactive desktop
option and whether or not it works.
