delphi多线程应用
在这里我教大家如何使用Delphi语言的多线程
第一步:安装好Delphi,并打开;
第二步:给Delphi窗体上加一个Button按钮,一个statictext;
第三部:给button 按钮写点击的代码;代码这样写:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, Buttons;
type
TForm1 = class(TForm)
BitBtn1: TBitBtn;
procedure BitBtn1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
function MyThreadFunc(P:pointer):Longint;stdcall;
var
i:longint;
DC:HDC;
S:string;
begin
DC:=GetDC(Form1.Handle);
for i:=0 to 500000 do begin
S:=Inttostr(i);
Textout(DC,10,10,Pchar(S),length(S));
end;
ReleaseDC(Form1.Handle,DC);
end;
procedure TForm1.Button1Click(Sender: TObject);
var
hThread:Thandle;//定义一个句柄
ThreadID:DWord;
begin
//创建线程,同时线程函数被调用
hthread:=CreateThread(nil,0,@MyThreadfunc,nil,0,ThreadID);
if hThread=0 then
end;
