在Delphi中创建Windows服务需要遵循以下步骤:
TService
类并覆盖其方法。例如:unit ServiceUnit;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, SvcMgr, Dialogs;
type
TMyService = class(TService)
procedure ServiceExecute(Sender: TService);
procedure ServiceStart(Sender: TService; var Started: Boolean);
procedure ServiceStop(Sender: TService; var Stopped: Boolean);
private
{ Private declarations }
public
function GetServiceController: TServiceController; override;
{ Public declarations }
end;
var
MyService: TMyService;
implementation
{$R *.DFM}
procedure ServiceController(CtrlCode: DWord); stdcall;
begin
MyService.Controller(CtrlCode);
end;
function TMyService.GetServiceController: TServiceController;
begin
Result := ServiceController;
end;
procedure TMyService.ServiceStart(Sender: TService; var Started: Boolean);
begin
{ Place your code here }
Started := True;
end;
procedure TMyService.ServiceStop(Sender: TService; var Stopped: Boolean);
begin
{ Place your code here }
Stopped := True;
end;
procedure TMyService.ServiceExecute(Sender: TService);
begin
{ Place your code here }
end;
end.
.dpr
文件中,将TMyService
设置为主要的服务对象。例如:program MyServiceProgram;
uses
SvcMgr,
ServiceUnit in 'ServiceUnit.pas' {MyService};
{$R *.RES}
begin
Application.Initialize;
Application.CreateForm(TMyService, MyService);
Application.Run;
end.
sc
命令行工具或者使用TServiceController
组件。sc create MyService binPath= "C:\path\to\your\service.exe"
sc start MyService
sc stop MyService
sc delete MyService
在这个过程中,你可以根据需要自定义服务的行为,例如在ServiceStart
和ServiceStop
方法中添加自己的代码,以及在ServiceExecute
方法中实现长时间运行的任务。
