# Miscellaneous Modules This module contains a grab-bag of unrelated miscellaneous libraries, *none* of which is an extension. ## Application Online Update Checking When we start LO, first `InitUpdateCheckJobThread` is created, via `UpdateCheckJob::execute()` (from `extensions/source/update/check/updatecheckjob.cxx`), as a reaction to a `onFirstVisibleTask` event. It waits 25 seconds (so that it does not interfere with the startup itself), and then calls `UpdateCheck::initialize()` (from `extensions/source/update/check/updatecheck.cxx`). This creates one more thread, `UpdateCheckThread`, that regularly checks whether we have reached the time when we should ask for the update. If yes, asks for that, and shows the download button in the menu (if the new update is available). The update server will decide if there is an update available based on the user-agent string created by UpdateInformationProvider::getUserAgent, the data used there is extracted from instdir/program/versionrc and the update server takes the buildid into account, so to experiment with the updates from a dev version getUserAgent needs to return a recognized id. ## OLE Automation Bridge A bridge between "OLE automation" and UNO, so you can use UNO services from JScript, VBScript, etc. See `udkapi/com/sun/star/bridge/oleautomation/ApplicationRegistration.idl` This is initialized in `Desktop::Main()` in `Desktop::OpenClients_Impl()` by creating the service `com.sun.star.bridge.OleApplicationRegistration`, which is implemented by `OleServer_Impl`. See `extensions/source/ole/` ## ActiveX Control This allows embedding LO into a Win32 application as an ActiveX control. See `extensions/source/activex/` ## Spotlight Provider On macOS, this allows indexing ODF documents with Spotlight. See `extensions/source/macosx/spotlight/` ## Scanner Support You can scan from LibreOffice, using platform specific backends like TWAIN/SANE. See `extensions/source/scanner/` .3 LibreOffice 核心代码仓库文档基金会
