windows 服务程序和桌面程序集成（六）集成安装、启动、卸载功能

系列文章目录链接：

把windows服务程序的安装、启动等功能集成到自身的桌面程序上，需要引入单元uszhnServiceUtils.pas。

该单元包括如下函数：

unit uszhnServiceUtils;

interface

uses
  WinApi.Windows, WinApi.Messages, System.SysUtils, WinApi.Winsvc, VCL.Dialogs,
  vcl.ExtCtrls,
  system.Classes,

  System.Win.Registry;

type
  TServiceState = (ssUnKnow, ssTimeOut, ssRuning{运行中},
  	ssWait{等待},
    ssStop{停止},
    ssUnInstall{未安装},
    ssPause{暂停});


//启动服务
function StartServices(const SvrName: string): Boolean;

function Always_StartServices(const SvrName: string; var ErrorMsg: String): Boolean;
//SvrName服务名;下同

//停止服务
function StopServices(const SvrName: string): Boolean;
///<summary>一直停，直到服务停下为止<sammary>
function Always_StopServices(const SvrName: string; var ErrorMsg: String): Boolean;

//查询服务状态;返回状态类型
function QueryServiceState(const SvrName: string): TServiceState;
///<summary>持续询问<sammary>
function Always_QueryServiceState(const SvrName: string; const tgtState: TServiceState;  TimeOut: Integer = 5*60*1000): TServiceState;



//注册服务
///<summary>建立一个服务</summary>
function CreateServices(const SvrName, FilePath: string): Boolean;
///<summary>建立一个服务;并且有服务描述</summary>
function CreateServiceWithDesc(const SvrName, FilePath, SrvDesc: string): Boolean;


function AddServiceDesc(const SvrName, SrvDesc: String): Boolean;
//服务名,FilePath: 服务路径

//卸载服务
function DeleteServices(const SvrName: string): Boolean;
//服务名


procedure GetServiceNames(Names: TStrings; DisplayNames: TStrings = nil;
  const Service_Type: integer = $30; const Computer: PChar = nil);

我们在桌面程序界面上增加如下按键：安装服务、启动服务、停止服务、卸载服务。

uMainForm_Application.pas单元代码如下：

unit uMainForm_Application;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  system.DateUtils,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.ExtCtrls;

type
  TForm_Application = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    Button4: TButton;
    Panel1: TPanel;
    Label1: TLabel;
    Button5: TButton;
    Button6: TButton;
    Button7: TButton;
    Button8: TButton;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure Button4Click(Sender: TObject);
    procedure Button5Click(Sender: TObject);
    procedure Button6Click(Sender: TObject);
    procedure Button7Click(Sender: TObject);
    procedure Button8Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form_Application: TForm_Application;

implementation

uses
  uWorkerThread, uszhnServiceUtils;

{$R *.dfm}

procedure TForm_Application.Button1Click(Sender: TObject);
begin
   //创建工作线程
  if WorkThread = nil then
     WorkThread := TWorkThread.Create;
  WorkThread.FreeOnTerminate := True;    //完成后直接释放
end;

procedure TForm_Application.Button2Click(Sender: TObject);
begin
  WorkThread.Pause;
end;

procedure TForm_Application.Button3Click(Sender: TObject);
begin
  WorkThread.Continue;
end;

procedure TForm_Application.Button4Click(Sender: TObject);
begin
  WorkThread.Terminate;
  while not WorkThread.Finished do
    begin
      Sleep(200);
    end;
  WorkThread := nil;
end;

procedure TForm_Application.Button5Click(Sender: TObject);
begin
  if CreateServices('Service1', ParamStr(0)) then
    begin
      Memo1.Lines.Add('服务安装成功: Service1');
    end
  else
    begin
       Memo1.Lines.Add('服务安装失败: Service1   xxxxx');
    end;
end;

procedure TForm_Application.Button6Click(Sender: TObject);
var
  T : TDateTime;
  FServiceState : TServiceState;
begin
  if StartServices('Service1') then
    begin
      FServiceState := QueryServiceState('Service1');
      T := IncSecond(Now,10);
      while FServiceState <> ssRuning do
        begin
          if Now > T then
            begin
              Memo1.Lines.Add('服务: Service1 启动失败！(Service), 超时未启动(10秒)');
              Exit;
            end;
          Application.ProcessMessages;
          Sleep(200);
          FServiceState := QueryServiceState('Service1');
        end;

      Memo1.Lines.Add('   ----------------------------------------------');
      Memo1.Lines.Add('   |  启动服务成功: Service1' );
      Memo1.Lines.Add('   ----------------------------------------------');
    end
  else
    begin
       Memo1.Lines.Add('*********************************************************');
       Memo1.Lines.Add('*                  Service  服务启动失败                *');
       Memo1.Lines.Add('* ServiceName: Service1 (服务启动后名称)');
       Memo1.Lines.Add('*********************************************************');
    end;
end;


procedure TForm_Application.Button7Click(Sender: TObject);
var
  FServiceState : TServiceState;
begin
  if StopServices('Service1') then
    begin
      FServiceState := QueryServiceState('Service1');
      while FServiceState <> ssStop do
       begin
         Application.ProcessMessages;
         Sleep(100);
         FServiceState := QueryServiceState('Service1');
       end;
      Memo1.Lines.Add('   ----------------------------------------------');
      Memo1.Lines.Add('   |  停止服务成功: Service1' );
      Memo1.Lines.Add('   ----------------------------------------------');
    end
  else
    begin
       Memo1.Lines.Add('*********************************************************');
       Memo1.Lines.Add('*                  Service  服务停止失败                *');
       Memo1.Lines.Add('* ServiceName: Service1 (服务启动后名称)');
       Memo1.Lines.Add('*********************************************************');
    end;
end;

procedure TForm_Application.Button8Click(Sender: TObject);
var
  FServiceState : TServiceState;
begin
  if DeleteServices('Service1') then
    begin
      FServiceState := QueryServiceState('Service1');
      while FServiceState <> ssUnInstall do
        begin
           FServiceState := QueryServiceState('Service1');
           Application.ProcessMessages;
        end;

      Memo1.Lines.Add('服务卸载成功: Service1');
    end
  else
    begin
       Memo1.Lines.Add('服务卸载失败: Service1');
    end;

end;

end.

经过以上步骤，就彻底实现了双模程序，及实现了windows服务程序的完美调试，也实现了在程序自身完成服务的安装、启动、停止、卸载等功能。
