Delphi-PRAXiS - Sharing data between two Delphi applications

There are several ways to do so.*In this trick, we will use a file from memory to share a memory area, and be able to send data from one application to the other.*We will create two applications, one which write data and another that receives them.*In particular, we will make that text a TEdit looks the a Label of the other application. Application that writes the data creates a new application put a TEdit (Edit1) form changes the code of the unit of the form by this: unit Unit1; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Edit1: TEdit; procedure FormCreate(Sender: TObject); procedure Edit1Change(Sender: TObject); procedure FormDestroy(Sender: TObject); private {Private declarations} public {Public declarations} end; type TCompartido = record number: Integer; String: String [20]; end; PCompartido = ^ TCompartido; var Form1: TForm1; Shared: PCompartido;
