I wrote the OnAfterPrint events into some log now and it looks now, that this is not called after printing the complete report, but after printing each "component" on it. Reading the manual I find this confirmed: it is called after each band at least. I was looking for something being called after the complete report has been output.

The event would be used to clear some data once the output has been created and thus Fast Reports no longer needs to have access to that data. Since the output is mandatory that shouldn't be problematic.

Thanks, will try this one! In those cases where I print/output without preview the user cannot cancel 😉

Hello, this is to let you know that there was a open source collaboration project started to create a formal specification of the Delphi language in Backus-Naur format (https://en.wikipedia.org/wiki/Backus–Naur_form). It is hosted on GitHub here: https://github.com/MHumm/DelphiGrammar David Hoyle contributed his Delphi 10.3 version as a starting point. If you want to participate in this endeavor, which might help developers of language tools, just drop me a message with your GitHub account name and I'll give you commit permission. Either via this forum or as an issue on that GitHub project. Currently I picked Apache 2.0 as license, but if necessary we can discuss to use something else. Cheers TurboMagic

Now you discussed this at length but it looks like no clear conclusion was reached yet and nobody seems to have done anything about this grammar. Looks like a grammar is not usefull at all... 😉

Hello, yesterday I released V3.1 of TComPortDrv, a RS232 handling component for Delphi. It is available here: https://github.com/MHumm/ComPortDriver/releases/tag/V3.1 And most likely via GetIt as well. There it's still V3.0, but I already sent in V3.1 to update the entry. What's new? fixed the wrong handle type used, which made it fail in 64 bit applications => it's 64 bit compatible now fixed a deadlock situation which could happen if somebody called MessageDlg from an eventhandler. That called that event handler again which called MessageDlg again which... 😉 So enjoy it TurboMagic

Next useful info: it is available via GetIt now as well!

Hello, I'm using D11.2 with FireDAC and a Firebird database. I have just set ExtendedMetadata in the DB Connection params to true to solve some other issues in some new part of the application. When running the app now this leads to a crash in previously working code. x := In that previously working code I do a FieldByName('MyColumn').AsInteger; The column is specified as SmallInt via some self defined domain. The crash now is an exception: First chance exception at $7720E292. Exception class EDatabaseError with message 'Feld 'MyColumn' cannot get accessed as type Integer . Process MyApp.exe (11560) (message translated from german) Why dos this crash now and how to fix it with .AsSmallInt not being available? Ok, I found out that it thinks my column to be a boolean now. But how does he know this? The dmomain is defined as SmallInt and no constraints.

Thanks for all the answers. It detected it since my domain contains "BOOLEAN" in its name. Learned something with this now. Good to know about boolean type in FB 3, but the application is currently still on 2.5. Can't do everything at the same time... 😉

Just try it out, but be aware that I'm not the developer of CodeCoverage.exe, just of the Wizard around it. 😉 The other project is linked to from my project site though.

Hello, do good and talk about... I'm currently shortly before releasing a new tool. It''s named "Delphi Code Coverage Plus" and is a completely rewritten and improved version of "Delphi Code Coverage Wizard". You can already get it on GitHub and it already works, the things before a 1.0 release I want to do are mostly cosmetic ones. Here is the link: https://github.com/MHumm/delphi-code-coverage-wizard-plus Now what can it do for me? It is a GUI tool which can generate everything needed to run the commandline Delphi Code Coverage tool that Delphi Code Coverage tool would run your unit tests and find out which lines of code your unit tests are actually run by the unit tests and which ones are never reached Why did I rewrite it and what's new/improved? The former Wizard (remember: I only reworte the wizard, not the command line tool itsself!) would generate the batch file to run the command line tool and create other necessary files, but if you changed something in your Delphi project, you would have to update these files/batch file yourself manually The new wizard got rid of JVCL components so it uses only what comes with Delphi itsself, which hopefully makes it easier for others to contribute The new wizard introduces a project format so you can load and modify an existing project, e.g. if you added more units to your project or need a different output format The new wizard can add itsself to Delphi's Tools menu if you like. The new wizard stores his position and window sze so it opens the same positionand with the same size new time it is started The new wizard should be HiDPI capable The new wizard can directly show the HTML output if you selected that one as output format What else is there to know? it was developed with 11.2, but most likely will compile and work fine with 10.4 For isntallation download the ZIP from GitHub or clone it, then open and run the project file There are plans to release it via GetIt package manager as well If you like this tool you can "star" it on GitHub 😉

Just to let you know that the development branch of that project now contains a much improved version, which will be released as V2.0 in the near future. What did improve? Fixed issues with units whith dots in their name by adding some parameter automatically Updated the version of CodeCoverage used to a current one, thus the generated HTML output looks much nicer Added further output formats Added further parameters Added the possibility to specify any parameters not already covered by the wizard Added the possibility to specify where these additional parameters will be placed in the generated batch file Create output dir etc. if that doesn't exist yet Bugfixes

Master branch is updated with new code and some documentation (format of that needs fixing though): there are some command line params now -O for opening and -R for opening and running a project file and Tools menu integration has been reworked to contain two entries now. If you place your DCCP project file inthe same directory as the dpr/dproj, you can run it from tools menu now... Enjoy!

I just commited an updated version: I fixed a bug where empty paths/file names were added to the .lst files under some circumstances. This really upset CodeCoverage.exe (it created an av in ntdll.dll!) The log-file output path is now the same as the report output path. The links in the new about dialog are opened in the browser now. If you pass a file name as command line parameter the tool will act as if you had clicked "Open" in the tool and loaded the file. I added some screenshots to the readme on GitHub. That's not a new release yet but some good improvements in my eyes. More should be comming over the next few days.

Define "near" 😉

I found out by talking to the one posting the bug report on the DE Delphipraxis forum, that this does not seem to be in the wizard but rather in the coverage tool itsself. We'll investigate. I cheched my project source and it has no JCL/JVCL units in its uses at all.

Ups, sorry! I had missed that one!

Gah! I'm sorry to report that a bug crept in. There's still some dependency on JCL or so in there at some place. I'll try to fix this tonight. So if you don't have JCL/JVCL installed it will not run at the moment.

Just to let you know that I just submitted the form to get it published in GetIt. Now that's EMBT's turn 😉

Not bad the idea, it just might require adding more syntax to { ToDo: "my list item" } comments. I'm also sure you know where you can file such requests officially. If you do that and post the number here others might vote for that.

Sorry for not answering earlier. I'm not often on English DelphiPraxis forum and it seems I don't get E-Mail notifications. Need to check settings for those. Aboue EAS: I guess you mean AES? The key is the key used for encryption descyption. means: both parties need to use the same key. If you just use the AES class the variant of AES algorithm picked/created depends on the length of the key you give. At least in the version in development branch (not sure if that's already in 6.4.1) there are AES128, AES192 and AES256 classes now which do not really check key length to find out which one to create. Init vector: if you use any block mode except ECB (and ECB is not recommended as this is the least secure one) the preceeding block is somehow combined with the data of the currently processed block. That means: if you encrypt the very same data twice, it usually will be encrypted differently because blocks depend on each other. This enhances security. When using ECB mode this is not the case and thus is should not be used. This init vector is just the data which is treated as "output of the former block processed" when calculating the very first block. So it must have a length of block size of the algorithm and you need to supply the same data for encryption and decryption. The recommendation is to use a different value each time you encrypt something. I hope this helps, if not let me know.

Hello, has anybody any hints for me why TShareContract or ShareContractFramework work in the example provided by Delphi 11.1 but not when I copy over that code to my application? So where's my difference? I call it from the OnClick handler of a TMenuItem and not a TButton but that shouldn't be the root cause. I call InitiateSharing but then the mouse cursor changes for just a brief moment and nothing pops up. When I run the demo and click the button it works and I get that popup... Cheers TurboMagic

Hello, I'm currently playing with Kastri's Camera demo, which is based on the Android Camera2 API. Now I'm struggeling with getting capabilities of the camera used and later on I even need to change some settings. After finding out how the basic structure of this demo works I added this method to get some capabilities as string to get started: function TPlatformCamera.GetCapabilities: string; var LCharacteristics : JCameraCharacteristics; Orientation : Integer; Obj : JObject; IntArray : TJavaObjectArray<integer>; i : Integer; begin LCharacteristics := FCameraManager.getCameraCharacteristics(FSelectedCamera); Obj := LCharacteristics.get(TJCameraCharacteristics.JavaClass.LENS_FACING); Orientation := TJInteger.Wrap(Obj).intValue; if (Orientation = TJCameraMetadata.JavaClass.LENS_FACING_FRONT) then Result := 'Camera: front' + sLineBreak else Result := 'Camera: back' + sLineBreak; Obj := LCharacteristics.get(TJCameraCharacteristics.JavaClass.CONTROL_AE_AVAILABLE_ANTIBANDING_MODES); end; FSelectedCamera is a JString and assigned where the component goes through the list of available cameras and selects the desired one. Reading which camera is selected already seems to work, since this just returns a simple integer value. But how to deal with CONTROL_AE_AVAILABLE_ANTIBANDING_MODES, which, according to the API docs API docs returns int[], which is some kind of array? How to access this from Delphi? And even more: CONTROL_AE_COMPENSATION_RANGE, which returns an array (with two elements) of Range<Integer>? And CONTROL_AE_COMPENSATION_STEP which returns a Rational? I haven't found the definition of this Rational type in Androidapi.JNI.JavaTypes or Androidapi.JNIBridge.

Meanwhile I learned that there's no support in the Java bridge yet to get access to these data types, which means one must implement some things on "the Java side".

Hello, I want to use TCameraComponent on Android to capture images with a frame rate as high as possible and search for something/detect something in the individual images. Questions: 1. Is the exposure time of relevance there? If yes, how can I set that? I didn't see anything regarding that. 2. Which Android camera API does TCameraComponent use? 3. If I use .MAP on the obtained bitmap I get a TBitmapData object, where I can call GetScanLine on. Which TPixelFormat do those bitmaps use? Is this the same format on all Android devices or how to set that? Regards TurboMagic
