Service! -start -stop. Help.

I implemented an application to run as service in Windows XP. It functions
correctly, however I have that to have access "Administrative Tools |
Services"
to be able to initiate the same one. I tried to make way prompt DOS and he
did not run. Somebody would know to say me as to make?

My test:

myapp /install                      --> OK
myapp -start                       --> not run

Thanks,
