本文主要讲解了如何使用delphi新建服务，停止系统服务，以及获取服务状态和新建系统服务器的方法，以下是关键代码：
unit Servicescontrol;
interface
uses Windows,Messages,SysUtils,Winsvc,Dialogs;
function StartServices(Const SvrName:String):Boolean;
function StopServices(Const SvrName:String):Boolean;
function QueryServiceStatu(Const SvrName: String):String;
function CreateServices(Const SvrName,FilePath:String):Boolean;
function DeleteServices(Const SvrName: String):Boolean;
implementation
//开启服务
function StartServices(Const SvrName: String): Boolean;
var
a,b:SC_HANDLE;
c:PChar;
begin
Result:=False;
a:=OpenSCManager(nil,nil,SC_MANAGER_ALL_ACCESS);
if a <=0 then Exit;
b:=OpenService(a,PChar(SvrName),SERVICE_ALL_ACCESS);
if b <=0 then Exit;
try
Result:=StartService(b,0,c);
CloseServiceHandle(b);
CloseServiceHandle(a);
except
CloseServiceHandle(b);
CloseServiceHandle(a);
Exit;
end;
end;
//停止服务
function StopServices(Const SvrName: String): Boolean;
var
a,b: SC_HANDLE;
d: TServiceStatus;
begin
Result := False;
a :=OpenSCManager(nil,nil,SC_MANAGER_ALL_ACCESS);
if a <=0 then Exit;
b:=OpenService(a,PChar(SvrName),SERVICE_ALL_ACCESS);
if b <=0 then Exit;
try
Result:=ControlService(b,SERVICE_CONTROL_STOP,d);
CloseServiceHandle(a);
CloseServiceHandle(b);
except
CloseServiceHandle(a);
CloseServiceHandle(b);
Exit;
end;
end;
//查询当前服务的状态
function QueryServiceStatu(Const SvrName: String): String;
var
a,b: SC_HANDLE;
d: TServiceStatus;
begin
Result := '未安装';
a := OpenSCManager(nil,nil,SC_MANAGER_ALL_ACCESS);
if a <=0 then Exit;
b := OpenService(a,PChar(SvrName),SERVICE_ALL_ACCESS);
if b <= 0 then Exit;
try
QueryServiceStatus(b,d);
if d.dwCurrentState = SERVICE_RUNNING then
Result := '启动' //Run
else if d.dwCurrentState = SERVICE_RUNNING then
Result := 'Wait' //Runing
else if d.dwCurrentState = SERVICE_START_PENDING then
Result := 'Wait' //Pause
else if d.dwCurrentState = SERVICE_STOP_PENDING then
Result := '停止' //Pause
else if d.dwCurrentState = SERVICE_PAUSED then
Result := '暂停' //Pause
else if d.dwCurrentState = SERVICE_STOPPED then
Result := '停止' //Stop
else if d.dwCurrentState = SERVICE_CONTINUE_PENDING then
Result := 'Wait' //Pause
else if d.dwCurrentState = SERVICE_PAUSE_PENDING then
Result := 'Wait'; //Pause
CloseServiceHandle(a);
CloseServiceHandle(b);
except
CloseServiceHandle(a);
CloseServiceHandle(b);
Exit;
end;
end;
{建立服务}
function CreateServices(Const SvrName,FilePath: String): Boolean;
var
a,b:SC_HANDLE;
begin
Result:=False;
if FilePath ='' then Exit;
a := OpenSCManager(nil,nil,SC_MANAGER_CREATE_SERVICE);
if a <= 0 then Exit;
try
b := CreateService(a,PChar(SvrName),
PChar(SvrName),
SERVICE_ALL_ACCESS,
SERVICE_INTERACTIVE_PROCESS or SERVICE_WIN32_OWN_PROCESS,
SERVICE_AUTO_START,SERVICE_ERROR_NORMAL,
PChar(FilePath),nil,nil,nil,nil,nil);
if b <= 0 then begin
ShowMessage( SysErrorMessage( GetlastError ));
Exit;
end;
CloseServiceHandle(a);
CloseServiceHandle(b);
Result := True;
except
CloseServiceHandle(a);
CloseServiceHandle(b);
Exit;
end;
end;
{卸载服务}
function DeleteServices(Const SvrName: String): Boolean;
var
a,b:SC_HANDLE;
begin
Result:=False;
a := OpenSCManager(nil,nil,SC_MANAGER_ALL_ACCESS);
if a <= 0 then Exit;
b :=OpenService(a,PChar(SvrName),STANDARD_RIGHTS_REQUIRED);
if b <= 0 then Exit;
try
Result := DeleteService(b);
if not Result then
ShowMessage(SysErrorMessage(GetlastError));
CloseServiceHandle(b);
CloseServiceHandle(a);
except
CloseServiceHandle(b);
CloseServiceHandle(a);
Exit;
end;
end;
end.
调用方法：
{启动服务}
StartServices(服务名);
{停止服务}
StopServices(服务名);
{新建服务}
CreateServices(服务名,exe文件路径);
{删除服务}
DeleteServices(服务名);
{获取服务状态}
string:=QueryServiceStatu(服务名);
