What The Hell Is This?

---

If you've ever had to make an installation program that had to start, stop, remove or otherwise manipulate a Windows NT Service then you'll find this useful. It's a collection of functions that can be used from an NSIS script (Nullsoft Installation System, http://www.nullsoft.com/free/nsis) to manipulate Windows NT (and hopefully 2000 and XP) Services.

If you don't know what I'm talking about then you don't need this, simple.

Most of the code is based on information found in the Microsoft Knowledge Base and the MSDN Platform SDK documentation.

I haven't released anything in quite a long time so if I've forgotten something or have generally fouled up somewhere then for gods sake tell me.

Feel free to send comments/suggestions/bug fixes/hate mail/biscuits to ximon_eighteen@3b2.com.

As long as you don't violate any nullsoft agreement that might be binding on an extension DLL for their NSIS product as far as I'm concerned you can do absolutely anything with this code, claim as your own if you like although that would be a bit low.

I'll answer any questions that I can, but I'm not responsible if this fouls up your system, use this at your own risk. If something does go wrong I'll do what I can to help, but I think this is highly unlikely ;-)

Distribution :

---

 - exdll.c
 - isadministrator.c
 - logonasservice.c
 - nsisapi.h
 - queryservice.c
 - readme.txt
 - sendservicecommand.c
 - winerror.h
 - winerror.c
 - Visual C++ 6.0 project file (.dsp) [ release & debug configurations ]
 - Services.nsi  [ example ]
 - FindService.nsi [ example ]

 The code is based on the exdll project that shipped with 0.98 of the NSIS
 distro. Building the project should result in a .dll file that you can then
 use with the CallInstDLL NSIS scripting command.

Known Bugs/Issues :

---

 - I don't think the SendServiceCommand should really support a delete
   option, perhaps it should be a separate function?
 - No other known issues.
