  1. Hi there, maybe its already too late, too tired today, but I just asking myself why the code doesn't create any "blue" breakpoints steps in the Except scope anymore ? All the other function shows debug breakpoints, and I also can debug them, only if an exception occurs, this is NOT catched here. (running under Macos Catalina). I'm just testing with the new Rx10.4.2, but I need a rest now, so maybe someone can spot the issue ? function TConnector.IsDeviceConnected : Boolean; var LTxt: String; begin try try if Assigned( FDevSelected ) then //<== for exapmple, here I see the "blue" breakpointe, and can debug begin if FConnection_Last.IsConnected then //<== this mayb rais an exception, but I cannot debug it in try - except scope Result := True else Result := False; end else begin Result := False; end; except on E : Exception do begin LTxt := E.Message; //<== the whole function has "blue" breakpoint steps, only these 3 lines not S4Debug_Step; //<== this is just an emprty function all as nop() replacemnt Result := False; //<== Nope, no breakpoints either end; end; finally S4Debug_Step; end; end;

    Delphi 10.4.2 first impressions

    I would propose, when 1st testing, better don't install unnecessary components. Normally I do some very pure test runs first, before I add more stuff. With that approach its easier to find the library or expert that causes issues.

    Delphi 10.4.2 first impressions

    Still testing, but so far it behaves very well. Feels all in all quite fast and responsive, much improved to my Rx1041. If it compiles now all my projects without big issues (and it looks like that), I would say its close to very satisfying

    Google Authenticator

    Thanks, I'm not sure how to check if an app calls some web services. Have you checked that its not sending anything ? To proof that sound too me like a big Wireshark setup with local proxy server, to catch any transmission. I would trust in that regard, as they have to loose a lot of reputation if they would cheat us. But the bad taste is still there, as they might change their mode at any time. I will check FreeOTP, that sounds interesting.
  5. Hi there, I found this small note about your own authenticator. Is anybody using Google Authenticator for your own apps ? Maybe there is a ready-made library somewhere, that makes it easy to use. What I suspect about Google Authenticator, that his is another piece of data Google is analysing, so it always knows when and where you logged in. Together with what Google already knows, this is maybe highly problematic. But I'm not sure about the Google Authenticator, and maybe its perfectly fine, do you have any experience with it ? I want to try that out, but also check alternative, own authentication systems.

    listview items width on run

    TListItemText has all properties for alignment; Align, VertAlogn; PlaceOffset You better check FindDrawable before access, call me paranoid, but I never trust any FindXxx method var Dwb : TlistItemDrawable; ... Dwb := AItem.View.FindDrawable('Text1'); if Assigned( Dwb ) and ( Dwb is TlistItemText ) then begin Text := Dwb as TlistItemText; ... end;

    Problems with FMX.CameraComponent Sample

    @Jim McKeeth Sorry Jim, I do not have much time right now. What I can say in general, I think the problem with the demos is that they were not set up in a proper folder representation. Like /Packages/Rx1033 /Packages/Rx1041 /Packages/Rx1032 /Src So that all different versions are nicely separated, and no IDE .dproj conversion is needed when opening with the wrong version. I think that is usually most of the time the provblem, that opening an older .dproj file with the newer IDE, but the IDE is not 100% able to convert and all parameters correctly (its simply too complex). A better library-structure would help to keep the samples up-to-date, and also to see whats already upgraded, and whats not. I came back to this topic triggered from the nice article here. Maybe the demos has to be seen as part of the library too ( so do I ) ?

    [Style] How to see a style designed for another OS

    Probably by loading on demand, see here in the german DP.
  14. I think VM on Mac is perfectly fine with their license. Anyway I payed so much for their stuff that I hardly care, I feel that I bought Apple already
  15. Maybe its worth to share the answer in your cross-post on SO. What brings me to the question if MacInCloud is a useful tool or not ? I considered to use MacInCloud in the transistion times, when OS version changes, to fastly and safely make early tests. Now I set up my own VM, installing stuff, etc., which is no big deal, but also takes some time. What I wanted to test if just starting MacInCloud, pre-configurated, can maybe reduce these test- and configuration time a lot. I would try with real devices, so not the simulator, as the SO answer also points to. Will such setup with MacInCloud is working flawlessly and make sense, or will I stay better with my VM setup ? I'm wondering who has good or bad experiences with MacInCloud.
