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;

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.

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.

No, mine is the same as yours.

LockType=5

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.

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.

The install files are located at my.embarcadero.com (registered products portal).

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.

You should check out https://github.com/danieleteti/delphimvcframework. What's DelphiMVCFramework DMVCFramework is a very popular Delphi framework which provides an easy to use, scalable, flexible RESTful, JSON-RPC and ActiveRecord framework for Delphi developers. DMVCFramework is the most popular Delphi project on GitHub and compiles for Windows (32 and 64bit) and Linux (64bit). DMVCFramework services can be compiled as console application, Windows Service, Linux daemon, Apache module (Windows and Linux) and IIS ISAPI (Windows). DMVCFramework works with Delphi 11 Alexandria, Delphi 10.4 Sydney, Delphi 10.3 Rio, Delphi 10.2 Tokyo, Delphi 10.1 Berlin, Delphi 10 Seattle.

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)

HandleCommand is an event handler, it should be a method of an object, not a procedure. You should add it to your TfrmMainClass.

You have multiple choice: - You can try to send money to Embarcadero. Maybe then they will be able to buy a better hardware. -Build a time machine. First travel back in time and install it while the "get it" was working.

Try to add https://docwiki.embarcadero.com/Libraries/Alexandria/en/System.Classes.ComponentPlatformsAttribute type [ComponentPlatformsAttribute(pidWin32 or pidWin64)] // Only supported on Win32 and Win64 TMyComponent = class(TComponent)
