Registering a QtService as a message source

When writing messages via logMessage, then the Windows Event Viewer usually displays:

The description for Event ID ( 0 ) in Source (...) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: [actual message]

To avoid that, and to only have the message itself displayed, the following steps have to be taken:

a) Create a dummy.mc file like this:

LanguageNames=(English=0x409:MSG00409)

MessageId=0x1
Severity=Error
SymbolicName=MSG_BAD_COMMAND
Language=English
%1
.

b) Compile that dummy.mc file into a resource file:

mc dummy.mc

c) Add the resource file to your project:

RC_FILE = dummy.rc

d) Register the service executable as the message source by adding a registry key:

HKLM/System/CurrentControlSet/Services/Eventlog/Application/[Service Name]/EventMessageFile

That entry needs to point to the executable.

Steps a/b/c could be handled by the service.pri file. Step d could be performed by the service's self-installing routine.
