I sometimes install a password protected URL handler that calls terminate. BTW, also, they don't daemonize under Linux/run as service under windows. Maybe they aren't supposed to? They are not supposed to. That kind of thing is a design decision only you can make. This is the reason why web components have the TWebHandler and TApplication classes split: the webhandler does the work, the TApplication part determines what kind of application it is. I have executables that can run as a service or as a normal binary.

[Lazarus] Bug: CodeTools can't handle some generics
I am prepping to release version 2 of Bare Game, and in doing so am producing a "lets make a game" video series where I show a cross platform game running on Windows, Linux, Macintosh, and the Ouya console (a basic android system). I am hoping the video tutorial series which takes someone from a non programming background, introduces them to Free Pascal and Lazarus, and teaches basic of game development skills using Bare Game in a series of 14 videos. The problem is there are a few issues with CodeTools which I think may hamper new users. One problem in particular deals with code insight, which helps Lazarus users find methods on objects. Users can normally press ctrl+space after the dot of an object and get a drop down list of properties, methods, and other information related to a class or record. In Bare.Game library though I make use of clonable objects (cloning a sprite, cloning a pen, cloning a vector graphics path for example) and their definitions typically look like this: TGraphicObject = class(TPersistObject, ICloneable) TPen = class(TGraphicObject) I filled out a CodeTools bug report with a video. Mantis report: http://mantis.freepascal.org/view.php?id=27847 Video: http://cache.getlazarus.org/video/bare_game_code_tools.mp4 If I could get some help understanding CodeTools I could fix these errors and possibly a few others, but I honestly hesitate to put out this tutorial when I know new users are going to struggle if CodeTools constantly jumps to source code units telling theme there is an error, when in fact there are no errors. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Yes, my question ist specific to tiOPF and better dicussed in the right newsgroup (i have found later by RTFM). The issue with the TitListView is now fixed for me, but i see tiOPF is not 'Out of the box' if you want to see a demo running (its not running yet). So we can close this question.

Giving the problem 15 seconds of my time (a better solution could probably be realised with more thought)... Instead of a "check for updates" which does everything, make it a dialog which tracks the last used commit (SHA1 value). So if anything goes wrong like you described, you can always go back into that dialog and select the "revert to previous commit", and you are back in action. ;-) > Also, doing this requires a checkout. This will increase diskspace etc. Probably with SubVersion yes, but not a problem with Git. Git has the full history locally and you can switch to any commit in that history in an instant. Git previously noted, a git checkout with full history is still smaller than a single commit SVN checkout (which duplicates everything in the .svn directories). [this is how SVN used to work] Summary of workflow using the Git mirror: (dialog takes not of current SHA1 commit value) git stash // save local changes you might have made git fetch git stash pop // reapply your local changes (maybe this should be optional) (trigger the IDE recompile) ... compilation failure detected... (click that revert button) git checkout // git resets back to the last good commit A basic working package of this is still possible 15-30 minutes, even with the extra step.
