There is a way to encrypt the Firebird database, the is a sample in Firebird documentation. Unlucky me I wasn't able to create a encryption/decryption module for Firebird, most because of no time, maybe you could try to create one and share the results and will have a lot of thanks and appreciations for that. Most encryption/decryption modules prices are tooo big.

I would capture that content (on exception of course) and will try to parse it for content that describes the error and display it to the user. But first I would try to collect all types of errors/html and create some kind of templates to make it easier for parser (from above) to get the right content.

SET SQL DIALECT 3; CREATE GENERATOR GEN_RECORD_NUMBER; SET TERM ^ ; CREATE OR ALTER TRIGGER ORDEN_BI FOR ORDEN ACTIVE BEFORE INSERT POSITION 0 as begin if ((new.number is null) or (new.number = 0)) then new.number = gen_id(GEN_RECORD_NUMBER,1); if ((new.guid is null) or (trim(new.guid) = '') ) then new.guid = '{' || uuid_to_char( gen_uuid() ) || '}'; end ^ SET TERM ; ^ I also use a GUID column as a unique field

I've moved all global variables to a Singleton

Delphi 10.3.3 SOAP Server (unknown source but the server has it's a php) Imported the wsdl, no changes made to the unit. Tested requests to the server with SoapUI and everything goes fine, from Delphi application - there is no luck. All responses are about Schema mismatch. Using event HTTPRio.onBeforeExecute checked the request and it is the same as tested in SoapUI. Questions: How to debug a request? How to check if the request meets the schema rules? Any advanced docs/video on how to build SOAP client/server applications?

Try to add BEGIN END for SUSPEND CREATE PROCEDURE "CUSTITEMMOVEMENT" ( "CUSTNO" INTEGER ) RETURNS ( "RNO" INTEGER, "TNAME" VARCHAR(5), "TDATE" DATE, "DOCNO" VARCHAR(12), "QTY" NUMERIC(18, 2), "NETPRICE" NUMERIC(18, 4), "ITEMNO" VARCHAR(20), "ITEMNAME" VARCHAR(40) ) AS BEGIN FOR SELECT IM.RNO,IM.TNAME,IM.TDATE,IM.DOCNO,IM.QTY, IM.NETPRICE,IM.ITEMNO, IT.ITEMNAME FROM ITEMMOVEMENTS IM JOIN ITEMS IT ON IT.ITEMNO=IM.ITEMNO WHERE (IM.CUSTNO= :"CUSTNO") ORDER BY IM.TDATE, IM.DOCNO INTO :"RNO",:"TNAME",:"TDATE",:"DOCNO",:"QTY",:"NETPRICE",:"ITEMNO",:"ITEMNAME" DO BEGIN SUSPEND; /* Line 26 is here */ END END ;

IBExpert, and you can get a free license if have WIN1251 (Russian) code page installed in your system

Is you are using FireDAC than transactions are used internally, but you could use transactions like in your example. The "commit" is required if the the DataSet is set to no auto commit, e.g. cached updates. If I am wrong please correct me.

I am trying to Internationalize a application using integrated Delphi feature using documentation. After the application is created I use "Resource DLL Wizard" and translated obtained forms. In documentation it is said that the application will automatically be translated by system locale settings, but also I would like to change the UI language from application settings. To test the application in different language I set the language from Project->Languages->Set Active, all builds and compiles but not working, an execution error rises Exception EResNotFound in module ExHome.exe at 00250A7D. Resource TfrmFDGUIxFormsError not found. Exception EClassNotFound in module ExHome.exe at 00065F62. Class TFDGUIxErrorDialog not found. Don't know how to fix that. Tried to remove FDGUIxWaitCursor and FDGUIxErrorDialog from project datamodule, but no luck. And the second question is how to change the language from application settings and use that language on next start? Can I save the current application language in a INI file? And how to add other translations for strings (messages, exceptions, etc.) used in units? Delphi 10.3 Application with FireDAC SQLite database

Never worked with SQLite before and now for my project need to use it but some questions and misunderstandings came on application model (VCL). I used to use GUID data type for unique records, in SQLite table the field 'uuid' is declared as binnary 'guid', and I created a trigger to generate the value, in application in FDConnection.Params.GUIDFormat=guiBinary, but when try to execute a clean FDQuery a message shows up: [FireDAC][DatS]-10. Fixed length column [uuid] data length mismatch. Value length - [32], column fixed length - [16]. changing FDConnection.Params.GUIDFormat=guiString show up a 'Wrong guid format error'. and here is the trigger for guid generation: CREATE TRIGGER demotable_after_insert AFTER INSERT ON demotable FOR EACH ROW WHEN (NEW.uuid IS NULL) BEGIN UPDATE demotable SET uuid = lower(hex(randomblob(16))) WHERE id = NEW.id; END So the question is how to deal with guids in Delphi+SQLite? Should I generate them from application? Do I need to make some mappings? The second question is about using generators for auto incremented fields, is this possible?

It works for me

Think VM as a computer, it's not a container (like docker or jail), so if you think of moving the IDE to the VM than you should move the project(s) to othe VM and all the dev tools needed for that project. I did like that. I've created a VM for Delphi development only, put my Delphi projects there and all the dev tools I need for my projects development, configured the git (git+TurtoiseGit+Bitbucket) and a additional a backup method. Every time I want to make some changes to my system (not in development manner), OS upgrade, IDE upgrade/downgrade - I make a full copy of my VM (because I have only a VMWare Player), but if you have a VMWare Workstation you could use the VM snapshot that is much comfortable.

The question is good, an it is hard to answer. First of all you need to define/create the architecture of the cloud model, to specify the services you need and how to interact with each other, to take care of load balancing and resource consumption. When I migrated my desktop app to the cloud the first this I've done is splitting the functionalities of my app, not all but some (btw I use Amazon AWS and Digital Ocean, but not hard to do in in Azure too). Then create a cloud infrastructure model to chose the right cloud service to you app functionality, the best example here is the database and a rest api server. Also need to remember of security. In the end I've came out with a simple desktop application (because some of functionalities are translated to cloud services) the connects to the cloud and is secure, load balanced, and works from anywhere in the world. But, the easier and simple way is: Buy a vps with needed OS Put you application in there And run it

I've seen something like that in EhLib

Could it be in write permissions? Did you try to run the programm elevated?
