使用MQ传输结构体信息

代码如下：

unit Unit1;

interface

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

type
 MQDataInfo = record
   ID : Integer;
   Name : PAnsiChar;
   Value : PAnsiChar;
   Image : TBitmap;
 end;
 PMQDataInfo = ^MQDataInfo;

type
 TForm1 = class(TForm)
   Memo1: TMemo;
   Button1: TButton;
   LabeledEdit1: TLabeledEdit;
   LabeledEdit2: TLabeledEdit;
   LabeledEdit3: TLabeledEdit;
   Button2: TButton;
   Button3: TButton;
   Image1: TImage;
   procedure Button1Click(Sender: TObject);
   procedure Button2Click(Sender: TObject);
   procedure Button3Click(Sender: TObject);
 private
   { Private declarations }
 public
   { Public declarations }
 end;      

var
 Form1: TForm1;
