摘要:

1.窗口的初始化

2.窗口切换的处理

3.读取本地数据

4.发送请求数据

5.接收推送行情数据

6.画图

 

第一部分 视图的结构和数据初始化

SListView.cpp同时实现了两种功能，一个是推送行情，一个是请求行情。

int CSListView::OnCreate(LPCREATESTRUCT lpCreateStruct) 方法中，

1.初始化GridCtrl

2.准备底部标签

3.注册了窗口句柄，用于接收主动推送行情的行情数据

4.设置了一个定时器，每隔3秒主动向行情服务器请求一次行情数据。

int CSListView::OnCreate(LPCREATESTRUCT lpCreateStruct) 方法中的
{
        // Create GridCtrl  初始化GridCtrl
	CRect rect;
	GetClientRect(rect);
	if (!m_Grid.Create(rect, this, IDC_SLISTVIEW_GRID, WS_CHILD|WS_BORDER|WS_TABSTOP|WS_VISIBLE|WS_VSCROLL|WS_HSCROLL))
	{
		TRACE("CSListView::OnCreate(...), Create m_Grid Error.\n");
		return -1;
	}

	// fill it up with stuff
	m_Grid.SetEditable(FALSE);
	m_Grid.SetListMode(TRUE);
	m_Grid.SetHeaderSort(FALSE); 
	m_Grid.SetSingleRowSelection(FALSE);
	m_Grid.EnableDragAndDrop(TRUE);
	m_Grid.SetGridLines(GVL_NONE);
	m_Grid.EnableTitleTips(TRUE);
	m_Grid.SetRowResize(TRUE);
	m_Grid.SetColumnResize(TRUE);
        .....

         //底部标签
	CTSKTabManagerItem* pItem;
	CString	strName;

	strName.LoadString(IDS_SLISTVIEW_CLASS);
	pItem = new CTSKTabManagerItem();
	pItem->SetCaption(strName);
	AddItem(SL_WORKTAB_CLASS, pItem);

	strName.LoadString(IDS_SLISTVIEW_A);
	pItem = new CTSKTabManagerItem();
	pItem->SetCaption(strName);
	AddItem(SL_WORKTAB_A, pItem);

	//strName.LoadString(IDS_SLISTVIEW_MSMALL);
	strName = _T("中小板");
	pItem = new CTSKTabManagerItem();
	pItem->SetCaption("中小板");
	AddItem(SL_WORKTAB_MSMALL, pItem);
        .....

        主动推送行情，注册窗口句柄，在 \StkNet\Src\StkReceiver.cpp中实现
	AfxGetStkReceiver().AddRcvDataWnd(GetSafeHwnd());

	//行情列表刷新速度 
	SetTimer(SLV_TIMER_REFRESH, 20000, NULL);
}

 

推送行情

G:\stock\TskingVS2019\src\Client\StkUI\View\SListView.cpp

定义了一个接收数据的消息

BEGIN_MESSAGE_MAP(CSListView, CView)
	
	
	ON_MESSAGE(WM_APP_STKRECEIVER_DATA, OnStkReceiverData)
END_MESSAGE_MAP()

消息处理

LRESULT CSListView::OnStkReceiverData(WPARAM wParam, LPARAM lParam)
{
	PCOMMPACKET	pCommPacket	=	(PCOMMPACKET)lParam;

	switch(wParam)
	{
	case CStock::dataReport:
		if (pCommPacket && CStock::dataReport == pCommPacket->m_dwDataType 
			&& pCommPacket->m_dwCount > 0)
		{
			CStockContainer & container = AfxGetSListStockContainer();
			// 如果当前股票列表显示的日期不是今天的，返回，不做刷新
			DWORD	dwDate = -1;;
			AfxGetSListStockContainer().GetCurrentType(NULL,NULL,&dwDate);
			if (-1 != dwDate && dwDate != CSPTime(pCommPacket->m_pReport[0].m_time).ToStockTimeDay())
				return 0L;

			container.Lock();

			// 刷新数据
			BOOL	bNeedReSort	=	FALSE;
			for (DWORD i=0; i<pCommPacket->m_dwCount; i++)
			{
				int	id = 0;
				if (container.GetStockInfo(pCommPacket->m_pReport[i].m_szCode, NULL, &id))
				{
					CStockInfo	& info	=	container.ElementAt(id);
					UpdateStockInfoByREPORT(info, &(pCommPacket->m_pReport[i]));
					StockInfoChanged(id, info);
					bNeedReSort	=	TRUE;
				}
			}

			// 统计平均值刷新
			if (bNeedReSort)
			{
				container.SetAverage();
				//SetAverageItem(m_Grid, container, TRUE);
			}

			// 重新排序
			if (-1 != m_nColSort && bNeedReSort)
			{
				LPARAM	lParam	=	m_Grid.GetItemData(0, m_nColSort);
				if (lParam >= 0)
				{
					CStockContainer::m_pSortContainer	=	&container;
					container.m_nSortVariantID	=	lParam;
					container.m_bSortAscend		=	m_bSortAscend;
					m_Grid.SortItems(ItemCompareFunc, 0, TRUE);
				}
				m_Grid.Invalidate();
			}
			container.UnLock();
		}
		break;
	}
	return 0L;
}

 

WM_APP_STKRECEIVER_DATA 由以下几个地方发出：

1.通视驱动发出，

2.void CStkReceiver::NotifyWndRcvData(WPARAM wParam, LPARAM lParam)发出

G:\stock\TskingVS2019\src\Client\StkNet\Src\StkReceiver.cpp

void CStkReceiver::NotifyWndRcvData(WPARAM wParam, LPARAM lParam)
{
	for(int i=0; i<m_awndRcvData.GetSize(); i++)
		::SendMessage(m_awndRcvData[i], WM_APP_STKRECEIVER_DATA , wParam, lParam);
}

前者是通视驱动发送过来的消息处理后再发送给各窗口，后者是请求行情服务器得到数据后发送给各窗口。

step 1：各视图向CStkReceiver注册自己的窗口句柄

step 2：各视图定义自己的消息及处理函数。ON_MESSAGE(WM_APP_STKRECEIVER_DATA, OnStkReceiverData)

step 3：CStkReceiver向通视注册，用OnStkReceiverTsdata（）函数处理通视驱动发送过来的数据，处理后转发各个已注册窗口。

gSTOCKDLL.Stock_Init(m_hWnd,WM_APP_STKRECEIVER_TSDATA,RCV_WORK_SENDMSG)

行情服务器也注册了

LRESULT CStkReceiver::OnStkReceiverConnectserver(WPARAM wParam, LPARAM lParam)
{
	if (gNetTSDLL.LoadDriver("NetTS.dll")
		&& gNetTSDLL.Stock_Init(m_hWnd,WM_APP_STKRECEIVER_TSDATA,RCV_WORK_SENDMSG) > 0)
		return TRUE;
	return FALSE;
}

G:\stock\TskingVS2019\src\Client\NetTS\TSWnd.cpp

当队列有数据时，主动发送消息

// 分发数据线程，行情服务器主动推送线程 2019/06/08 by freeman
UINT TSDispatchThreadMain(LPVOID pParam)
{
	while(TRUE)
	{
		UINT nMsgType = 0;
		PRCV_DATA pRCV_DATA = NULL;
		if (CTSCache::GetInstance().PopPacket(nMsgType, pRCV_DATA))
		{
			ASSERT(pRCV_DATA && pRCV_DATA->m_pData);
			if (pRCV_DATA && pRCV_DATA->m_pData)
				CTSWnd::GetInstance().SendMessage(nMsgType, (LPARAM)pRCV_DATA);

 

 

请求行情

调用链条：ListView.cpp里面的定时器发起SendRequestQuote(FALSE)->调用StkNet项目里面的

AfxGetStkReceiver().RequestStockData(CStock::dataReport, stocks.GetData(), stocks.GetSize(), 0, 0);

->调用StkNet项目里面的gNetTSDLL.RequestStockData(nDataTypeTS, pStocks, nSize, nKType, nDataCount);

->痛过gNetTSDLL全局变量调用NetTS项目里面的函数

int WINAPI RequestStockData( int nDataType, TW_STOCK * pStocks, int nSize, int nKType, int nDataCount )

->调用NetTS项目里面的CTWSocket::GetInstance().RequestStockData( nDataType, pStocks, nSize, nKType, nDataCount );

在这个函数里面，构造发送Askbuffer的二进制字节流发送给行情服务器。

具体实现过程如下：

step 1：SListView.cpp的定时器，每隔3秒定时向行情服务器发起一次请求行情数据

void CSListView::OnTimer(UINT nIDEvent) 
{
	if (SLV_TIMER_REFRESH == nIDEvent)
	{
		SendRequestQuote(FALSE);
	}
	
	CView::OnTimer(nIDEvent);
}

 

step 2：执行SendRequestQuote(FALSE);发起请求行情

SendRequestQuote(FALSE)，当bForced=FALSE时，会判断是否是在交易时间内，如是则发起请求，否则不发起请求。

请求

用AfxGetStkReceiver().RequestStockData(CStock::dataReport, stocks.GetData(), stocks.GetSize(), 0, 0);发起向行情服务器的主动请求

//发球请求行情
void CSListView::SendRequestQuote(BOOL bForced)
{
	if (!AfxGetStkReceiver().NetEngineIsWorking())
		return;

	static int nLastStart = -1;
	static int nLastCount = -1;

	BOOL bQuoteTipSended = FALSE;

	//判断目前是否在交易时间内
	BOOL bInTrade = CSPTime::InTradeTime(CSPTime::GetCurrentTime().GetTime(), 900);
	CView* pView = AfxGetStaticDoc()->GetActiveView();

	//如果是强制刷新. 则发起请求沪、深指数数据2019/06/06 by freeman
	if (bForced)
	{
		CStockContainer stocks;
		CStockInfo info;
		if (AfxGetStockContainer().GetStockInfo(STKLIB_CODE_MAIN, &info))
			stocks.Add(info);
		if (AfxGetStockContainer().GetStockInfo(STKLIB_CODE_MAINSZN, &info))
			stocks.Add(info);
		if (stocks.GetSize() > 0)
			AfxGetStkReceiver().RequestStockData(CStock::dataReport, stocks.GetData(), stocks.GetSize(), 0, 0);//发起请求行情：请求沪、深指数
	}

	//如果是强制刷新或者股票列表窗口处于激活状态，则发起请求当前窗口股票列表的数据
	if (bForced || pView == this)
	{
		CCellRange cr = m_Grid.GetVisibleNonFixedCellRange();//非固定
		int nStart = cr.GetMinRow() - 1;
		int nCount = cr.GetMaxRow() - cr.GetMinRow() + 1;
		CStockContainer& container = AfxGetSListStockContainer();
		container.Lock();
		if (nStart >= 0 && nCount > 0 && container.GetSize() > 0 && (bInTrade || bForced || nLastStart != nStart || nLastCount != nCount))
		{
			nLastStart = nStart;
			nLastCount = nCount;
			//从AfxGetSListStockContainer()中找出当前窗口的股票列表，并发送请求
			AfxGetStkReceiver().RequestStockData(CStock::dataReport, container.GetData()+nStart, min(nCount,container.GetSize()-nStart), 0, 0);//发起请求行情：请求当前窗口的股票列表
			bQuoteTipSended = (0 == nStart && nCount >= 9);
		}
		container.UnLock();
	}


	//如果目前是在交易时间内。2019/06/06 by freeman
	if (bInTrade)
	{
		// 预警系统所需股票行情刷新
		CAlarmCondContainer& conds = AfxGetProfile().GetAlarmCondContainer();
		CStockContainer stocks;
		stocks.SetSize(0, conds.GetSize() + 5);
		for (int i = 0; i < conds.GetSize(); i++)
		{
			ALARMCOND cond = conds.GetAt(i);
			CStockInfo info;
			if (AfxGetStockContainer().GetStockInfo(cond.m_szCode, &info))
				stocks.Add(info);
		}
		CStockInfo infoMain, infoMainSzn;
		if (AfxGetStockContainer().GetStockInfo(STKLIB_CODE_MAIN, &infoMain)
			&& AfxGetStockContainer().GetStockInfo(STKLIB_CODE_MAINSZN, &infoMainSzn))
		{
			stocks.Add(infoMain);
			stocks.Add(infoMainSzn);
		}

		//  行情QuoteTip 需要行情数据
		if (!bQuoteTipSended)
		{
			CStockContainer & container = AfxGetSListStockContainer();
			container.Lock();
			for (int i=0; i<9 && i<container.GetSize(); i++)
				stocks.Add(container.ElementAt(i));
			container.UnLock();
		}

		if (stocks.GetSize() > 0)
