// ---------------------------------------------------------------------------
// 设置服务的描述
void TService1::SetDescription(WideString Desc)
{
    SC_HANDLE hSCM;
    SC_HANDLE hService;
    SERVICE_DESCRIPTION sd;

    hSCM = OpenSCManager(
        NULL,
        NULL,
        SC_MANAGER_ALL_ACCESS);
    if (hSCM == 0)
    {
        return;
    }
    hService = OpenService(
        hSCM,
        this->DisplayName.c_str(),
        SERVICE_CHANGE_CONFIG);
    if (hService == 0)
    {
        return;
    }

    sd.lpDescription = Desc.c_bstr();

    ChangeServiceConfig2(
        hService,
        SERVICE_CONFIG_DESCRIPTION,
        & sd);
    CloseServiceHandle(hService);
    CloseServiceHandle(hSCM);
}

void __fastcall TService1::ServiceAfterInstall(TService *Sender)
{
    // 安装结束以后, 设置服务的描述
    this->SetDescription
        (L" 我的描述 描述 喵");
}
