Question

有没有人尝试将delphi附加到Windows Server 2008 64位下的自己的Windows服务（32位应用程序）进程中？

当我尝试这样做时，我收到错误：无法创建流程。参数不正确。

如果你们中的任何一个人知道如何做到这一点，那将非常感谢你的帮助。

谢谢！

虽然您可以调试Delphi服务，但您需要跳过许多环节才能使其正常运行。我从不打扰并只是确保我的服务既可以作为服务运行，也可以作为标准应用程序运行。当我想调试时，我作为标准应用程序运行，因此避免了所有的麻烦。

为了这个答案的目的，我已经将所有代码整理成一个文件，但是你想要以不同的方式构建它。

program MyService;

uses
  SysUtils, Classes, Windows, Forms, SvcMgr;

type
  TMyService = class(TService)
  private
    procedure ServiceStart(Sender: TService; var Started: Boolean);
    procedure ServiceStop(Sender: TService; var Stopped: Boolean);
    procedure ServicePause(Sender: TService; var Paused: Boolean);
    procedure ServiceExecute(Sender: TService);
    procedure ServiceContinue(Sender: TService; var Continued: Boolean);
  protected
    FDescription: string;
    FEventLogSourceName: string;
    procedure Initialise; virtual; abstract;
    class function CreateRunner: TObject; virtual; abstract;
  public
    constructor Create(AOwner: TComponent); override;
    function GetServiceController: TServiceController; override;
  end;
  TMyServiceClass = class of TMyService;

{ TMyService }

constructor TMyService.Create(AOwner: TComponent);
begin
  inherited;
  Initialise;
  OnStart := ServiceStart;
  OnStop := ServiceStop;
  OnPause := ServicePause;
  OnExecute := ServiceExecute;
  OnContinue := ServiceContinue;
end;

procedure TMyService.ServiceStart(Sender: TService; var Started: Boolean);
begin
  Started := True;
end;

procedure TMyService.ServiceStop(Sender: TService; var Stopped: Boolean);
begin
  Stopped := True;
end;

procedure TMyService.ServiceContinue(Sender: TService; var Continued: Boolean);
begin
  ServiceStart(Sender, Continued);
end;

procedure TMyService.ServicePause(Sender: TService; var Paused: Boolean);
begin
  ServiceStop(Sender, Paused);
end;

procedure TMyService.ServiceExecute(Sender: TService);
var
  Runner: TObject;
begin
  Runner := CreateRunner;
  Try
    while not Terminated do begin
      ServiceThread.ProcessRequests(True);
    end;
  Finally
    FreeAndNil(Runner);
  End;
end;

var
  Service: TMyService;

procedure ServiceController(CtrlCode: DWORD); stdcall;
begin
  Service.Controller(CtrlCode);
end;

function TMyService.GetServiceController: TServiceController;
begin
  Result := ServiceController;
end;

procedure RunAsService(ServiceClass: TMyServiceClass; var Service);
var
  Application: TServiceApplication;
begin
  Application := SvcMgr.Application;
  Application.Initialize;
  Application.CreateForm(ServiceClass, Service);
  Application.Run;
end;

procedure RunAsStandardExecutable(ServiceClass: TMyServiceClass);
var
  Application: TApplication;
  Runner: TObject;
begin
  Application := Forms.Application;
  Application.Initialize;
  Runner := ServiceClass.CreateRunner;
  Try
    while True do begin
      Try
        Application.HandleMessage;
      Except
        Application.HandleException(Application);
      End;
    end;
  Finally
    FreeAndNil(Runner);
  End;
end;

procedure ServiceMain(ServiceClass: TMyServiceClass);
begin
  if FindCmdLineSwitch('RunAsApp', ['-', '/'], True) then begin
    RunAsStandardExecutable(ServiceClass);
  end else begin
    RunAsService(ServiceClass, Service);
  end;
end;

begin
  ServiceMain(TMyService);
end.

要使用此功能，您需要创建一个继承自TMyService的新类，并实现Initialise和CreateRunner。 CreateRunner是关键。在我的服务中，这会创建一个对象，该对象又会打开一个侦听套接字，以供客户端进行通信。

标准应用代码非常基本。它甚至没有终止机制 - 它在while True循环内运行。这与我的调试需求无关。

您是否尝试以管理员身份运行IDE？

我已经在Win64下完成了这样的进程附加，但据我记忆，我必须以管理员权限运行IDE。
