You do not need to use the DLL. You already have complete DLL code as far as I can tell. I think it is possible to convert that code to Delphi. I cannot be sure about the details of C# encryption method. It seems like DES, CBC and PCKS#7 padding. You need to confirm that information. Once you have all details, there are several free encryption libraries available for Delphi which can help you do the same directly in your project without any need for a DLL. You can install LockBox from GetIt as an example. There are other alternatives and you may want to check some of them. In case you are using older versions of Delphi like Delphi 7, you can still build your own DLL using a recent version in case you are not able to use the cryptography library in your Delphi version. Nowadays there is a lot of AI use. They can also help you convert that C# code into Delphi. if you choose to do it that way just make sure that final code is actually correct.

I am missing hints displayed when mouse cursor waits on form objects while working on VCL form design. Show designer hints is checked in the options. Can anybody reproduce? There must be something on my daily system. VM test system seems to be working fine. Go figure.

You might want to use https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer BTW, I personally value logging which helps finding where it stops

Browsers mostly do GET request. How do you make a POST request using explorer? BTW, your example code feels like you are not actually bound to DataSnap. I suggest you to check out MARS-Curiosity https://github.com/andrea-magni/MARS

@Kazantsev Alexeysolution worked just fine. Thank you. @Serge_Gthank you, too.

Hello, I want to conditionally change stock ImageListItemBottomDetail appearance TListViewItem (not the list but a single item) background color at runtime. Stylebook - background changes for whole background as far as I can see. Any help is appreciated. Thanks & Regards, Ertan

Hello, I tried to import below URL and resulting unit has errors. https://einvoiceserviceturmobtest.luca.com.tr/InvoiceService/ServiceContract/InvoiceService.svc?wsdl I don't know if WSDL is erroneous or Delphi cannot cope with it. I wonder if there is a way to have it imported properly. Any help is appreciated. Thanks & Regards, Ertan

Problem was indeed the packed. Removing it solved the problem. Thank you.

Hi, There is a DLL that has demo project in C#.NET code that I would like to convert into Delphi public struct AcquirerAmount { public uint id; public ulong amount; } public struct InposEcrPayment { public const ushort MAX_ACQUIRER_COUNT = 8; public ulong totalAmount; public uint totalCount; [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)] public AcquirerAmount[] acquires; } So far I converted above struct as below but data incoming is not correct. I believe that Delphi conversion is not correct. TInposAcquirerAmount = packed record Id: UInt32; Amount: UInt64; end; TInposEcrPayment = packed record TotalAmount: UInt64; TotalCount: UInt32; Acquires: Array[0..7] of TInposAcquirerAmount; end; Any help is appreciated. Thanks & Regards, Ertan

I tested it on Android 12 and and it is working just fine. Original SO answer was missing the case match of the function and its declaration type which I should be careful for the next time. Thanks for the help.

Hello, Android has 24H/12H hour display format setting. I wanted to format my time values displayed as in system settings but I couldn't find how to read that specific is24HourFormat value. Delphi TFormatSettings does not include that information. There are earlier SO threads like this one. But that code gives me Invoke error: method not found. I also tried to import "android/icu/text/DateFormat" that I found in another SO answer and the app crashes without any error displayed. What would be the correct way to read that system setting? Thanks & Regards, Ertan

Speaking about Delphi 12.2 Inline Update 1. I am told that Windows 10 and Windows 11 changes the experience. Delphi is giving problems on Windows 11 and identical (down to installed components) system on Windows 10 works just fine.

When I was adding Delphi 12.2 in our build server I remember below value was missing in rsvars.bat BDSLIB=C:\Delphi12.2\lib You need to point it to your correct directory.

Answer to your question depends on your needs. I don't use ISS or Nginx for about 200 clients using MARS Curiosity as my REST server. mORMot2 is another Open Source Client-Server ORM SOA MVC framework and uses REST which tested to serve millions of requests under certain conditions. It is up to you to choose your REST server framework and any load balancer if you need it.

If you want to prevent others accessing the data input in the application, you can encrypt a SQLite3 database and data will not be able to read by other software unless your encryption key and method is found. https://docwiki.embarcadero.com/CodeExamples/Sydney/en/FireDAC.SQLite_Encryption_Sample There are a lot to consider for saving data to disk file or reading from it. A database system already handles these for you.
