Delphi XE Code Parser Error: "Expected"> ", but". " found."

Question

After adding IdUDPServer to my form and trying to insert some code into the OnUDPRead event, I cannot add any component to my form at design time and cannot start the application.

is there any way to solve this?

There are two errors in this error handler. To fix them, you can

• delete the System. from TArray<System.Byte> (in interface and implementation)
• add IdSocketHandle to use list in interface

I have not researched yet, but after these changes, the code can be compiled.

So the full code will be

 unit Unit12; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, IdSocketHandle, // <-- added IdBaseComponent, IdComponent, IdUDPBase, IdUDPClient, IdUDPServer; type TForm12 = class(TForm) IdUDPClient1: TIdUDPClient; IdUDPServer1: TIdUDPServer; procedure IdUDPServer1UDPRead(AThread: TIdUDPListenerThread; AData: TArray<Byte>; ABinding: TIdSocketHandle); private { Private declarations } public { Public declarations } end; var Form12: TForm12; implementation {$R *.dfm} procedure TForm12.IdUDPServer1UDPRead(AThread: TIdUDPListenerThread; AData: TArray<Byte>; ABinding: TIdSocketHandle); begin // end;
