如何注册反注册系统服务

//注册

BOOL Install(char *szServiceName)
{
if (IsInstalled())
return TRUE;

//打开服务控制管理器
SC_HANDLE hSCM = ::OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
if (hSCM == NULL)
{
MessageBox(NULL, _T("Couldn't open service manager"), szServiceName, MB_OK);
return FALSE;
}

// Get the executable file path
TCHAR szFilePath[MAX_PATH];
::GetModuleFileName(NULL, szFilePath, MAX_PATH);

char szDependence[100];
strcpy_s(szDependence, sizeof(szDependence), "MSSQL$SQLEXPRESS");//表示该服务对SQLServer的依赖

//创建服务
SC_HANDLE hService = ::CreateService(
hSCM, szServiceName, szServiceName,
SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS,
SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
szFilePath, NULL, NULL, _T(""), NULL, NULL);

if (hService == NULL)
{
::CloseServiceHandle(hSCM);
MessageBox(NULL, _T("Couldn't create service"), szServiceName, MB_OK);
return FALSE;
}

::CloseServiceHandle(hService);
::CloseServiceHandle(hSCM);
return TRUE;
}

//反注册

BOOL Uninstall(char *szServiceName)
{
if (!IsInstalled())
return TRUE;

SC_HANDLE hSCM = ::OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);

if (hSCM == NULL)
{
MessageBox(NULL, _T("Couldn't open service manager"), szServiceName, MB_OK);
return FALSE;
}

SC_HANDLE hService = ::OpenService(hSCM, szServiceName, SERVICE_STOP | DELETE);

if (hService == NULL)
{
::CloseServiceHandle(hSCM);
MessageBox(NULL, _T("Couldn't open service"), szServiceName, MB_OK);
return FALSE;
}
SERVICE_STATUS status;
::ControlService(hService, SERVICE_CONTROL_STOP, &status);

//删除服务
BOOL bDelete = ::DeleteService(hService);
::CloseServiceHandle(hService);
::CloseServiceHandle(hSCM);

if (bDelete)
return TRUE;

return FALSE;
}

先贴上试试，下回再加注释。还会加上启动服务和停止服务的部分
