Hi Uwe, Hopefully none. In theory there is no way for the User to edit the fields until the Dataset is put in Edit or Insert modes. I have had a couple of error reports, I use EurekaLog, where the report is that the Dataset isn't in Edit or Insert mode, with the error happening when the User ostensibly clicks on Save/Post in the DBNavigator. This suggests that the User has edited a field somehow and then clicked Save/Post but there is no evidence of the Dataset being put into either mode in the trace. It has left me a little baffled. Hence the query about there being some key combination that the User may have stumbled on. Ian

RE the monitor I am using - It is an AOC U2790VQ. The cheapest 4k monitor I could find. Oh the screen real estate I can now work in/with. 🙂 For what I do, they are ideal. I did have to update my old video card as it didn't have display ports to feed the monitor. Such a sacrifice. 😉

Perhaps. I am running in 3840 x 2160. Having said that it doesn't retain its resizing between usages. I tried to set my monitor to 1920x1080 to test but Windows went all funny on me. 😞 I guess it will need someone with a a lower resolution to test. Ian

Hi Thomas, Win 10, D10.4.1, 32bit. GExperts svn 3287. I regret to advise that the issue still persists. 😞 Just in case there was some interaction, I disabled all other add-ins. Same result. Regards, Ian

Updated via the Web installer with only one hiccup - It couldn't find the Patch 2 stuff to presumably delete it. It flagged it twice then opened Windows Explorer at the apparent directory, I just closed Explorer, and the install continued successfully to the complete install. The only comparability issue I have found so far is with CnPack/Wizards 1.2.0.1010, and that is an annoyance, not a deal breaker.

Hi Team, Win 10, D10.4. 32 bit. From my App main form, Form1, I open a sub-form, Form2, using TForm2.Create(nil).Show; Whilst in the Form2 I may open a further sub-sub-form, Form3, from Form2 using TForm3.Create(nil).show; When the Form3 opens the main form appears between Form2 & Form3. 😞 Is this an issue with D10.4? I can't test previous versions anymore, my PC had a hardware meltdown and I had to reinstall everything, including the OS, from scratch. 😞 So I have only re-installed D10.4. If it isn't specific to D10.4, is there a work around to stop the main form from showing? I must confess, I don't understand why the main form is showing given as far as I know I haven't set any ownership by using ...Create(self).show. Thoughts, suggestions, solutions, education welcome. Regards & TIA, Ian

HI Remy, So. It was education. 😉 Never ever looked at or used PopupMode or PopupParent. To confess, I re-read the reference and the relevant Delphi help several times and was still unsure exactly what it was telling me. So, I experimented. I have ended up with Forms 1, 2 & 3 all set with PopupMode set to pmAuto and that resolves my issue. Not sure if that is technically correct, but it works for me. Thank you for the pointer/education. Regards, Ian

EurekaLog will do the same thing.

Hi Team, I have had the practice of making the form large enough during IDE development to place all the non-visual components off to the side or below the visual components during development and setting the form height & width so the Form is the correct height and width. This has worked well, until now. In the past my and my users have used 1920 x 1080 screens so everything was fine. I have just installed a 3940 x 2160 monitor. 🙂 Oh the joy of it all. 🙂 Any way, when I now run the App(s) the various forms are too condensed, covering some of the visible components. 😞 Of course, if I shrink the forms to their desired run-time size and comment out the height/width instructions, all is fine. So, to my question.. Is there a mechanism to detect the DPI and adjust the Form height accordingly?? something like.. height := ScreenDPI() * iDesiredHeight; Appreciate any suggestions, Regards & TIA, Ian

Tks Remy, this works perfectly on all the different resolutions I have tried. Regards, Ian

Hi Remy, Apologies, yes I should have mentioned I am using D10.4. Thanks you for the suggestions, I shall give them a try. Regards, Ian

Hi Team, D10.4, 32bit App, Win 10. I am calling a sub form from a sub form as follows.. // MyForm := TMyForm.Create(self); MyForm.sFormID := '3'; // Pass a key value. MyForm.Show; // It all works fine. I close the sub-sub form in the FormClose event as follows.. // Action := caFree; // I close the sub-form the same way.. // Action := caFree; // Problem - When I close the sub form I get an Access violation error. If I remove the "Action = caFree" from the sub form it closes without issue. Can somebody please enlighten me as to what is going on and how to resolve it? Regards & TIA, Ian

Hi Remy, Ahhh. Whew! That's what I have been doing. Thank you for the education. Regards, Ian

Hi Remy, Now that is enlightening. Thank you. So, if I don't put 'Action = caFree' in the OnClose event, when does the from get destroyed. Or, to ask in another direction, how can I ensure the form is destroyed when it is closed? Regards & TIA, Ian

Hi Team, Found it! I progressively removed components/code from Form A until the issue disappeared. Turns out to be a component from a well know component library supplier. I will test the same component in a basic test App to confirm and let them know. Thank you for your guidance and assistance. I have learnt a couple of things from you. Much appreciated. Regards, Ian

Hi Uwe, Yes, they had different names. Kas Ob, Thank you. I will digest and have a play. Will respond later with my results. Regards, Ian

Hi Kas Ob, Regrettably, no. 😞 Regards, Ian

Hi Kas Ob, I tried the same App in D10.3.3 with the same result. I have continued with Create(nil) when creating the forms. I sort of follow what you are saying above. Using your terminology, normally I would expect B to be closed before A. As a test I closed A while B was still open, I got the error. 😞 It is definitely something specific with my App. As indicated previously, I created a dummy App, only components were buttons to call the next form, with the same hierarchy and there was no issue. For now I will just not use 'Action := Free;' in the close of A. Regards & Tks, Ian

Hi Team, Thank you for your inputs. Application structure. MainForm => Form1 => Form2. I changed (self) to (nil). Same issue. I don't want Form2 Modal as it needs to show while the User continues in Form1. I created a bare bones app with the same structure. I didn't get the issue when closing Form1 after closing Form2. 🙂 In my main App I created a new, empty Form2. I got the error again when I tried to close the Form1 after closing Form2. 😞 The error still happens if I disable the Action := caFree in Form2, but not if I disable it in Form1. The error generated is per the attached image. 'DBiLogViewer.exe' is the name of the App. Regards, Ian

Hi Team, Is it possible to have and display a TLabel in D10.4's TTitleBarPanel? I can put the Label on the panel but it doesn't show. Is there a Demo of the TTitleBarPanel usage anywhere? Regards & TIA, Ian

Tks. I did find that example/demo. Your suggestions noted. Regards, Ian P.S. I use BitDefender AV and it flags the App with a TTitleBarPanel 😞 I am confident it is OK so I told BD to ignore it.

Hi Guys, I want to have just the Help border icon, biHelp, visible on a form but it seems to require the SystemMenu icon, biSystemMenu, as well. Is there any way to have just the Help icon? Regards & TIA, Ian

Tks Remy, I half expected that. I did briefly, a while ago, have a look at the Custom Title Bar concept but was not impressed by it. I will have another look. Regards, Ian

Hi Thomas, The issue has returned. Haven't used it for a bit but did today after updating to rev 3236. It occurs in both 10.3.3 & 10.4. Regards, Ian

Hi Team, Can I allow a Form to resize vertically only, not horizontally at all? If so, how please? Regards & TIA, Ian
