Sendmessage pointer of array

[th_bone]

Hi,

ja funktioniert gut - ich finde das ist eine schöne möglichkeit variablen zwischen meinen
Programmen auszutauschen

einfach eine form mit einem label + button code hineinkopieren und 2x das Prog starten..

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

{ Basiert auf CodeSnippet [url]http://www.swissdelphicenter.ch/de/showcode.php?id=418[/url] }

type
  TWMMYMessage = record
    Msg: Cardinal;   // ( first is the message ID )
    Handle: HWND;    // ( this is the wParam, Handle of sender)
    Info: Longint;   // ( this is lParam, pointer to our data)
    Result: Longint;
  end;

  Mymessage = record
    msgtext: String[20];
    msgint : integer;
  end;

  TForm1 = class(TForm)
    Label1: TLabel;
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);

  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
    procedure DefaultHandler(var Message); override;
    procedure WMMYMessage(var Msg: TWMMYMessage);
  end;

var
  Form1: TForm1;
  WM_OURMESSAGE: DWORD;
  mymsg: mymessage;
  strtest : string[30];

implementation

{$R *.dfm}

procedure TForm1.DefaultHandler(var Message);
var
  ee: TWMMYMessage;
begin
  with TMessage(Message) do
  begin
    if (Msg = WM_OURMESSAGE) then
    begin
      ee.Msg    := Msg;
      ee.Handle := wParam;
      ee.Info   := lParam;
      // Checking if this message is not from us
     if ee.Handle <> Handle then
        WMMYMessage(ee);
    end
    else
      inherited DefaultHandler(Message);
  end;
end;

procedure TForm1.WMMYMessage(var Msg: TWMMYMessage);
var
 text: string;
begin
  text:=string(pchar(pointer(Msg.Info)));
  delete(text,1,1);
  Label1.Caption := text;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  SendMessage(HWND_BROADCAST, WM_OURMESSAGE, Handle, integer(@strtest));
  //SendMessage(HWND_BROADCAST, WM_OURMESSAGE, Handle, integer(@mymsg));
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
 mymsg.msgtext:='test';
 mymsg.msgint:=1234;
 strtest:='strtest';
end;

initialization
  WM_OURMESSAGE := RegisterWindowMessage('broadcast message');

end.
