Question

Delphi 实现 定时模拟键盘按键

这一部分函数我看不懂
给思路也没用

所以，直接给我源码
实现点击button1后，每隔10秒钟自动按键H
再点击button1，停止

thanks

添加一个timer1控件+button1，将里面的代码全替换如下就可以了
unit Unit1;

interface

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

type
TForm1 = class(TForm)
Button1: TButton;
Timer1: TTimer;
procedure Button1Click(Sender: TObject);
procedure Timer1Timer(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;
i:integer;//模拟按键时间
implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
if Timer1.Enabled=true then
begin
i:=0;//清零
Timer1.Enabled:=false;
end
else
begin
i:=0;//清零
Timer1.Enabled:=true;
end;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
i:=i+1;
if i mod 10=0 then
keybd_event($72,0,0,0);//$72是Ｈ键的虚拟键值，若要h健则是改为$48
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
i:=0;//初始化i
Timer1.Enabled:=false;
end;

end.
