From 0dfa0fdb3a851b1ff69a0f0b308a3e1371286a57 Mon Sep 17 00:00:00 2001 From: Iain Patterson Date: Sun, 2 Mar 2014 18:29:45 +0000 Subject: [PATCH] Allow editing service dependencies. Service dependencies can now be queried or set on the command line via the DependOnService and DependOnGroup parameters, or via the GUI in the new Dependencies tab. Service dependencies can be set using either their key name or display name. For example: nssm set DependOnService RpcSs which is equivalent to: nssm set DependOnService "Remote Procedure Call (RPC)" Group dependencies can be set with or without the group identifier prefix, which for some reason is not actually described in the documentation; instead readers are invited to consult the header files for the value of SC_GROUP_IDENTIFIER, which it turns out is the + symbol. For example: nssm set DependOnGroup +UIGroup which is equivalent to: nssm set DependOnGroup UIGroup The prefix is always printed when query group dependencies. The GUI presents a editbox into which either service or group dependencies can be typed. The group prefix is mandatory when editing dependencies via the GUI. --- README.txt | 10 ++- gui.cpp | 49 +++++++++++- messages.mc | Bin 146650 -> 147452 bytes nssm.rc | Bin 53034 -> 55400 bytes registry.h | 2 + resource.h | 4 +- service.cpp | 197 ++++++++++++++++++++++++++++++++++++++++++++++++- service.h | 5 ++ settings.cpp | 205 +++++++++++++++++++++++++++++++++++++++++++++++++++ settings.h | 6 ++ 10 files changed, 474 insertions(+), 4 deletions(-) diff --git a/README.txt b/README.txt index df12238..32051ab 100644 --- a/README.txt +++ b/README.txt @@ -62,7 +62,7 @@ an application which has exited.
