Talk:NSIS Simple Service Plugin

This is a great plugin. Almost perfect for our needs, but missing some features. For example, I cannot set the load order group when creating a service. Very rare, but a required for me. Sorta wished the code was written with something more common than Pascal so I could code it in.

Changing the return value of ExistsService really caught me off guard! I thought 1.21 was broken until I looked at the changelog :) If anyone else is here because of a similar problem, ExistsService now returns 0 on success, and non-zero otherwise.

This is a great plugin. Much better than Servicelib.nsh.

Code example:

# Installer sections
Section -Main SEC0000

    ...

    ; Install the service using NSIS Simple Service Plugin 
    SimpleSC::InstallService "$(^Name)" "Chromodoris" "16" "2" "$INSTDIR\Chromodoris.exe" "" "NT AUTHORITY\NetworkService" ""
    Pop $0 ; returns an errorcode (<>0) otherwise success (0)
    IntCmp $0 0 +3
    MessageBox MB_OK|MB_ICONSTOP "$(^Name) installation failed: could not create service."
    Abort
    
    SimpleSC::SetServiceDescription "$(^Name)" "UCNetworks' Chromodoris service"
    Pop $0 ; returns an errorcode (<>0) otherwise success (0)
    ; We don't care about the result.
    
    ; Start a service using NSIS Simple Service Plugin 
    SimpleSC::StartService "$(^Name)" ""
    Pop $0 ; returns an errorcode (<>0) otherwise success (0)
    IntCmp $0 0 +3
    MessageBox MB_OK|MB_ICONSTOP "$(^Name) installation failed: could not start service."
    Abort
