Delphi 12: The Embarcadero Gelt server could not be reached...
Lajos Juhász replied to PeterPanettone's topic in Delphi IDE and APIs
It's top secret. In case of docwiki we can get a backtrace: #0 /var/www/html/shared/BaseWiki31/includes/libs/rdbms/loadbalancer/LoadBalancer.php(1134): Wikimedia\Rdbms\Database->reportConnectionError('Connection time...') #1 /var/www/html/shared/BaseWiki31/includes/libs/rdbms/loadbalancer/LoadBalancer.php(749): Wikimedia\Rdbms\LoadBalancer->reportConnectionError() #2 /var/www/html/shared/BaseWiki31/includes/GlobalFunctions.php(2801): Wikimedia\Rdbms\LoadBalancer->getConnection(0, Array, false) #3 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LCStoreDB.php(45): wfGetDB(-1) #4 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LocalisationCache.php(412): LCStoreDB->get('en', 'deps') #5 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LocalisationCache.php(458): LocalisationCache->isExpired('en') #6 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LocalisationCache.php(334): LocalisationCache->initLanguage('en') #7 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LocalisationCache.php(371): LocalisationCache->loadItem('en', 'magicWords') #8 /var/www/html/shared/BaseWiki31/includes/cache/localisation/LocalisationCache.php(292): LocalisationCache->loadSubitem('en', 'magicWords', 'tree') #9 /var/www/html/shared/BaseWiki31/languages/Language.php(3177): LocalisationCache->getSubitem('en', 'magicWords', 'tree') #10 /var/www/html/shared/BaseWiki31/includes/MagicWord.php(352): Language->getMagic(Object(MagicWord)) #11 /var/www/html/shared/BaseWiki31/includes/MagicWord.php(280): MagicWord->load('tree') #12 /var/www/html/shared/BaseWiki31/includes/parser/Parser.php(4848): MagicWord::get('tree') #13 /var/www/html/shared/BaseWiki31/extensions/TreeAndMenu/TreeAndMenu_body.php(24): Parser->setFunctionHook('tree', Array) #14 /var/www/html/shared/BaseWiki31/includes/Setup.php(948): TreeAndMenu->setup() #15 /var/www/html/shared/BaseWiki31/includes/WebStart.php(88): require_once('/var/www/html/s...') #16 /var/www/html/shared/BaseWiki31/index.php(39): require('/var/www/html/s...') #17 {main} The quality portal have only a generic error message: Sorry, an error occurred trying to log you in - please try again.

Delphi 12: The Embarcadero Gelt server could not be reached...
Lajos Juhász replied to PeterPanettone's topic in Delphi IDE and APIs
It is most probably since Friday. There are posts on this server about the new trend that embarcadero likes to take the servers down. (If you can not download you cannot complain about the bugs.) -
When the quality portal is online you can create a ticket. Maybe one day Embarcadero can deliver a descent welcome page.

How do I terminate a thread that doesn't have an Execute method ?
Lajos Juhász replied to dormky's topic in Algorithms, Data Structures and Class Design
You cannot terminate the thread while it's blocked by sleep. +1 for SimpleEvent and Waitfor. -
You cannot add a property without a new class. If you don't want to extend the component you can store the additional information in a dictionary or in other data structure.
-
I've tested: uses MMSystem; procedure TForm1.Timer1Timer(Sender: TObject); begin sndPlaySound('C:\Windows\Media\Tada.wav', SND_NODEFAULT Or SND_ASYNC); end; no problems.

I believe it was starting with 11 and "enhanced" in 12. I know that they wrote 12 should be much better than earlier versions.
-
You install them as any other component. First you compile the runitme packages then the designtime and install them.

Issue with Color Names Overlay in Object Inspector
Lajos Juhász replied to Shrinavat's topic in Delphi IDE and APIs
If you enter a bug report without a test case they will close it as works as expected, I've been there a couple of times. Even if you submit a reproducible case the bug can stay opened for a decade. -
Issue with Color Names Overlay in Object Inspector
Lajos Juhász replied to Shrinavat's topic in Delphi IDE and APIs
I sometimes also get a bug that the selected property shows a value of a different property. I cannot enter a bug report as it's impossible to find out when that can happen. Also search in D12 is working even worse than in Delphi 11.2, here also I have had no time to create an example. I hope we can get a fix for some issues soon as we're moving to beta phase of our application. -
In my opinion It's not a standard Delphi file, you've installed something that creates them. I am using VCL and tried to create an empty fmx file none has produced a file with a dsv extension.

In order to work with jpg image format you must add the jpeg unit to your uses. IF you add a TImage named imgName then you can write: imgName.Picture.LoadFromFile('D:\Delphi_11_Community\MyProjects\Dinobase\dino_images\'+ sName + '.jpg');

Delphi 12 IDE, cannot create regions
Lajos Juhász replied to A.M. Hoornweg's topic in Delphi IDE and APIs
How? It's broken for days (there is a thread on this forum, you get an: Error creating issue: Could not load FunctionProvider class). -
Delphi 12 IDE, auto-formatter mutilates generics
Lajos Juhász replied to A.M. Hoornweg's topic in Delphi IDE and APIs
Do not try the formatter in source where you've multiline string. They should deprecate also the IDE editor it can't cope with the code. I've a section in my code that I cannot edit inside the IDE (a class with inner types). -
I believe that's the part of the new Embarcadero policy. 0 bugs in Delphi 12 due to the fact that we cannot report any new bugs.

Open a second connection to the database and fill the required fields. Here locate is your friend.
-
You should read more carefully the error message. You to open the query using the open method of the TFDQuery instead of ExecSQL.

Double click on the FDConnection to open the FireDAC Connection Editor.

while not SQLQuery1.Eof do begin currentLine := ''; for i := 0 to sqlQuery1.fieldcount-1 do currentLine := currentLine + ' ' + sqlQuery1.fields[i].asString; memOutput.Lines.Add(currentLine); SQLQuery1.Next; end; The above code doesn't require the Stringlist to iterate the fields of the query. To add a database the documentation states it should be a form of (https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Using_SQLite_with_FireDAC): Database=<path to SQLite database> While you've tried: SQLConnection1.Params.Add('D:Delphi 11 Community\My Projects\Connecting to SQLite\Data\dat2.sqlite'); You should do SQLConnection1.Params.Add('Database = '); append here the real path to the database. I believe instead of MemOutput.ClearSelection you wanted MemOutput.Clear.

The windows have to find the bpl (dll) to load it and it doesn't know about the library path.

A warning Canvas.TextWidth is valid only during painting, otherwise it's not guaranteed that the canvas has the correct font assigned. To be sure you can use https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.Graphics.TCanvas.RequiredState.
