Most probably there was no QP ticket to implement this logic?

Delphi dll ERROR_BAD_EXE_FORMAT
Lajos Juhász replied to isola's topic in RTL and Delphi Object Pascal
You can find out in the Help: Use debug .dcus The debug DCUs contain debug information and are built with stack frames. When this option is checked, the compiler adds the debug DCU path to the search paths specified in Debug Source Path on the Embarcadero Debuggers page. -
(replicable w/ source) Why do I always get Access Violation every time I rebuild ANY component? (Current solution is to Restart Delphi.. Why??)
Lajos Juhász replied to Al T's topic in FMX
Open a ticket at https://quality.embarcadero.com/ with the steps how to get Access Violation. -
(replicable w/ source) Why do I always get Access Violation every time I rebuild ANY component? (Current solution is to Restart Delphi.. Why??)
Lajos Juhász replied to Al T's topic in FMX
Yes you can, before you compile the package uninstall all the packages that depends on that one. That should improve the situation. Unfortunately this is a "known" issue and impossible to report (as it's hard to make the required test case). PS. For a project group I even have a situation that some days Access Violation is almost every time triggered when I compile an application without runtime packages. -
uses Xml.XMLIntf, Xml.XMLDoc; procedure TForm1.Button1Click(Sender: TObject); var MyXMLDocument : IXMLDocument; FounderNode : IXMLNode; begin MyXMLDocument := TXMLDocument.Create(nil); MyXMLDocument.Active := true; MyXMLDocument.Version:='1.0'; MyXMLDocument.DocumentElement := MyXMLDocument.CreateNode('ab', ntElement,''); MyXMLDocument.DocumentElement.DeclareNamespace('xsi', 'https://www.guru99.com/XMLSchema-instance'); MyXMLDocument.DocumentElement.DeclareNamespace('xsd', 'https://www.guru99.com/XMLSchema'); MyXMLDocument.DocumentElement.SetAttributeNS('xmlns', '','MyString'); FounderNode := MyXMLDocument.DocumentElement.AddChild('founder'); FounderNode.NodeValue:='Krishna'; MyXMLDocument.SaveToFile('TestOne01.XML'); MyXMLDocument.Active := false; end; You have to set the version and MyString should be the 3rd parameter not the second one.

There is a hope for Delphi 11 CE; my bet is that it's going to be released after Delphi 12. In order to learn more about the release date and roadmap I suggest to apply for a job at Embarcadero (that's the only legal way to get information).

You can access the windows handle using WindowHandleToPlatform. .

Google thinks this is a way to achieve it: https://www.advancedinstaller.com/forums/viewtopic.php?t=9364

This should be part of the installation of your application. For example Inno Setup can do it for you.

Make your application DPI aware and the dialog should be same on every settings.

It's not. There were Embarcadero webinars on this topic.

How to??? uses {IF EXISTS}CodeSiteLogging;{ELSE};

You can also test with regular VCL controls, the bug could be also in the DevExpress controls. With VCL placed on the form I don't have had placement problems.

A gem from the past (Goto)
Lajos Juhász replied to Mike Torrettinni's topic in Algorithms, Data Structures and Class Design
It's fine until you get an exception, which will result in a memory leak. -
FireDAC.Stan.Async amBlocking causing threadlock
Lajos Juhász replied to mattgorringe's topic in Databases
Never had deadlock when using amblocking. On the other hand in D11 sometimes amCancelDialog will not work on query. You must change for the connection before and change back after the query is finished. -
Update Subscription: Embarcadero policy seriously this bad?
Lajos Juhász replied to Al T's topic in Delphi IDE and APIs
(I believe earlier if you have had no valid licence there was no possibility to renew the previous one. The only option was to buy a new licence.) -
CodeInsight: Loading project [...] hanging
Lajos Juhász replied to omnibrain's topic in Delphi IDE and APIs
I do get codeinsight loading, however almost never freeze delphi. Maybe try using process monitor to spy what code insight and / or the IDE is doing. -
For third party and IDE settings you can use the migration tool (migrationtool.exe in the bin folder of the Delphi available for a couple of versions). As far as I know it will not download packages from getit, that could cause problems. I like to stay on the safe side and reinstall everything.

Check duplicates in TADOQuery
Lajos Juhász replied to karl Jonson's topic in Algorithms, Data Structures and Class Design
What is the metric for efficiency? You would have to iterate the query and for every record check the value in a memory structure if it's there you have duplicate if not insert into it. You can store the list in an array, list or a hash table. -
it's a bad idea, only English text should be saved as ANSI, otherwise you should always save as UTF-8.

Memory leak on TBlobField(FieldByname(field_name)).SavetoStream(Stream);

Hi, Usually I like to use TFDUpdateSQL to generate SQL's to update the database. Now I have a case where it would be easier to let FD generate the insert statement. However I fail to see how to customize the SQL. For some reason for Informix: function TFDPhysInfxMetadata.GetNameParts: TFDPhysNameParts; begin Result := [npCatalog, npSchema, npBaseObject, npObject]; end; In case of informix npCatalog that's makes no sense as it is the database name. npSchema is the user and that is a big no. I have a database with multiple users and rights. Is there a way to customize to generate the table name without prefixes? (When ApplyUpdates generates the insert or update statement.)

ExtractFilePath v TDirectory.GetCurrentDirectory
Lajos Juhász replied to Ian Branch's topic in General Help
The program was started with a different current folder option, or the WIN API SetCurrentDirectory was called somewhere from the application. -
You should check the implementation for that procedure: { ----------------------------------------------------- } { Variant manager support (obsolete) } { ----------------------------------------------------- } procedure GetVariantManager(var VarMgr: TVariantManager); begin FillChar(VarMgr, sizeof(VarMgr), 0); end; This will not fill the record properly.

Do not worry everything is going to work perfectly in the new 64 bit IDE.
