You can solve this problem, set Wordwrap to true. It is event documented: Vcl.StdCtrls.TButton.WordWrap inherits from Vcl.StdCtrls.TButtonControl.WordWrap. All content below this line refers to Vcl.StdCtrls.TButtonControl.WordWrap. Specifies whether the button text wraps to fit the width of the control. Set WordWrap to true to allow the display of multiple lines of text. When WordWrap is true, text that is too wide for the control wraps at the right margin. Set WordWrap to false to limit the text to a single line. When WordWrap is false, text that is too wide for the control appears truncated.

You cannot do achieve that in safe manner. For example: var t: TStringList; begin t:=TstringList.create; t.Free; end; How you are going to know if t is freed or not?

You are setting the date to today thus after the user clicks to reset the value will remain. Change the code to: procedure TForm1.btnResetClick(Sender: TObject); begin DateTimePicker1.Format:=' '; DateTimePicker1.Date:=0; end; Now it will change when the user clicks on the today.

The main form is the first form created using Application.CreateForm you can create forms before using the normal form constructor.
-
Close can cause access violation if the form is prematurely freed. Release makes sure that every event is finished before the form is freed.

You should code this in different way. You can find an example at https://www.thoughtco.com/display-a-login-password-dialog-1058469 unfortunately the code formatting is not correct but you can see the idea.

The correct code would be: // OPEN INPUT SCREEN FOR BOR DOSSIER try inputCheckForm := Tfrm_InputCheck.Create(Self); try inputCheckForm.ShowModal; finally inputCheckForm.Free; Release; // CLOSE THE CURRENT INPUT FORM end; except on E: Exception do DoShowException(E); end; https://docwiki.embarcadero.com/Libraries/Athens/en/Vcl.Forms.TCustomForm.Release

I see no problem to assign a TBytes to TValue. Where you find it impossible? var v: TValue; a: TBytes; begin setLength(a, 3); a[1]:=56; v:=TValue.From<TBytes>(a); ShowMessage(v.AsType<tBytes>[1].ToString); end;

Delphi 12: Installing via GetIt Corrupts the DPK of AsyncPro, VirtualTree, and SynEdit
Lajos Juhász replied to twe's topic in Delphi IDE and APIs
I get this all the time. I was unable to figure out the rule when the IDE does this. -
Just do a find in files.

Delphi 12 does not catch EXCEPTIONS ANYLONGER.
Lajos Juhász replied to alogrep's topic in Delphi IDE and APIs
No. The change was made to follow the Windows standard. Other languages assume or will change the exception masks. That was fragile in previous versions of the Delphi. They made the change to follow other languages and minimalize the possibilities to have problems when calling an external DLL. The price is that we have to adjust our code. -
MsgDlgIcons[TMsgDlgType.mtInformation]:=TMsgDlgIcon.mdiInformation; MessageDlg('Exiting the Delphi application.', mtInformation, [mbOk], 0, mbOk); You have to System.UITypes into the uses.

In my case SLIPFile is empty with an activated Delphi. -
I don't know what the IDE uses, but it is not usable on a mixed DPI multi monitor systems. I was forced to debug an aplication in such a scenario. Both the application and the IDE failed.

Delphi 12 Local CHM Documentation
Lajos Juhász replied to PeterPanettone's topic in Delphi IDE and APIs
It is online in read-only mode until the migration is finished. Attention: Embarcadero is migrating its customer bug and feature request reporting portal to a new system. This site will remain accessible as a read only repository. We'll shortly provide information on how to access and report bugs in the new portal. See https://blogs.embarcadero.com/embarcadero-quality-portal-migration/. I get the same image after F1 on that property. -
Why not keep the file locked while writing into it? In that case you have to do the hashing only when the file is done.

Firebird 5.0 with dbExpress (Delphi 12): unknown ISC error 0
Lajos Juhász replied to Achim Kalwa's topic in Databases
You can try to contact support and ask to open a ticket for dbExpress. As you wrote this is a new feature in Firebird that should be supported. -
Indy is a 3rd party free library. It is not owned or sponsored by Embarcadero. Embarcadero used it in the past, in recent versions it is replaced by Embarcadero implementation in the IDE and RTL.

Try to add the event handler using the object inspector. Delphi will generate the correct code. Select Server on the form then in Object inspector go to Events and double click on combobox for the OnHandleCommand event. (That is a more traditional way assign events.)

No, that was Turbo Pascal before OOP was introduced. https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Classes_and_Objects_(Delphi)
