delphi 用DDE控制Word

DDE(Dynamic Data Exchange)，称为动态数据交换。用于进程间的通讯，看看他如何来和Word交互。

在System页签下有TDdeClientConv组件，拖一个放到界面上，然后我们写如下代码：

unit Unit1;

interface

uses

  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

  Dialogs, OleServer, StdCtrls, DdeMan;

type

  TForm1 = class(TForm)

    Button1: TButton;

    DdeClientConv1: TDdeClientConv;

    procedure Button1Click(Sender: TObject);

  private

    { Private declarations }

//执行word的宏命令

    procedure RunMacro(macname:PChar);

  public

    { Public declarations }

  end;

var

  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

begin

//执行保存文件的宏命令

  RunMacro('[FileSave]');

end;

procedure TForm1.RunMacro(macname: PAnsiChar);

var

  macro: array [0..80] of char;

begin

  //设置于word的连接

  DdeClientConv1.SetLink('WinWord','System');

  //打开连接

  if not DdeClientConv1.OpenLink then

  begin

    ShowMessage('打开连接出错！');

  end;

  if not DdeClientConv1.ExecuteMacro(macname,False) then

  begin

    ShowMessage('执行宏命令出错！');

  end;

end;

end.
