Problems with scheduled task using ITaskScheduler,

Question

The code below executes without any error, but task didn't executed and I didn't see it in control panel . Please help

HRESULT CreateOnceActionTask(const wchar_t* taskName, const wchar_t* programPath, const wchar_t* params)
{
    HRESULT hr = S_OK;

    CComPtr<ITaskScheduler> taskScheduler;

        ReturnErrorMsg(hr, L"Failed to get IID_ITaskScheduler");

    // create task
    CComPtr<ITask> task;
    if(FAILED(hr = taskScheduler->NewWorkItem(taskName, CLSID_CTask, IID_ITask, (IUnknown**)&task)))
    {
        //if(FAILED(hr = taskScheduler->Activate(taskName, IID_ITask, (IUnknown**) &task)))
        ReturnErrorMsg(hr, L"Failed to create task");

        //taskScheduler->Delete(taskName);

        //return S_OK;
    }

    if(FAILED(hr = task->SetApplicationName(programPath)))
        ReturnErrorMsg(hr, L"Failed to set SetApplicationName");

    if(FAILED(hr = task->SetParameters(params)))
        ReturnErrorMsg(hr, L"Failed to set SetParameters");

    if(FAILED(hr = task->SetTaskFlags(TASK_FLAG_DELETE_WHEN_DONE)))
        ReturnErrorMsg(hr, L"Failed to set task flags");

    // save task
    CComPtr<IPersistFile> persistTask;  
    if(FAILED(hr = task->QueryInterface(IID_IPersistFile, (void **)&persistTask)))
        ReturnErrorMsg(hr, L"Failed to save task with IPersistFile");   

    if(FAILED(hr = persistTask->Save(NULL,TRUE)))
        ReturnErrorMsg(hr, L"Failed to save task with IPersistFile");

    // create trigger
    CComPtr<ITaskTrigger> taskTrigger;
    CComPtr<IPersistFile> persistTrigger = NULL;    
    WORD wTrigNumber = 0;

    if (FAILED(hr = task->CreateTrigger(&wTrigNumber, &taskTrigger)))

    triggerStruct.cbTriggerSize = sizeof (TASK_TRIGGER);
    triggerStruct.TriggerType = TASK_TIME_TRIGGER_ONCE;

    // 10 minutes from now
    COleDateTime oDate = COleDateTime::GetCurrentTime() + COleDateTimeSpan(0, 0, 1, 0);

    triggerStruct.wBeginDay     = oDate.GetDay();
    triggerStruct.wStartHour    = oDate.GetHour();

    // associate the trigger with the task
    if (FAILED(hr = taskTrigger->SetTrigger(&triggerStruct)))
        ReturnErrorMsg(hr, L"Failed to set trigger for the task");

    if (FAILED(hr = task->QueryInterface(IID_IPersistFile, (void **) &persistTrigger)))

    return S_OK;
