is there other way beside using HTML Reader C++ Class Library?

hi, how do i use string compare to get this value <span class="streaming-datum" id="yfs_l10_^ixic">2,190.06</span> before that line of code,there are many other html codes before and after it. my friend suggested to me using string compare this string "<span class="streaming-datum" id="yfs_l10_^ixic">" and if the compare value is true, do a loop and loop through the remaining text till i get a '<' but how do i continue looking for the value after &lt;span class="streaming-datum" id="yfs_l10_^ixic"&gt;

do i have to #include anything to use the innertext, outertext etc etc?

how do i extract 2,190.06 from here? <span class="streaming-datum" id="yfs_l10_^ixic">2,190.06</span> The ihtmldocument quite complicated to understand

Hi all, I got a txt file filled with HTML code extract from www.finance.yahoo.com this is the data from finance.yahoo.com Dow 10,212.73 +27.20 +0.27% Nasdaq 2,174.00 +2.80 +0.13% 10 Yr Bond(%) 3.6500% -0.0400 Oil 75.25 +0.82 +1.10% Gold 1,113.60 +10.10 +0.91 the 3 values i wanna extract from each stock is all the values above. all the values need to be read from the HTML text file of finance.yahoo.com. so, how should i create the method and what parameter should i pass in? should i create individual method for each stock? example double getDOW(param1, param2, param3, etc) or a generic method that can search any stock quote

Hi Guys, I got a txt file which contains html codes in it. <td class="ticker_name"><a href="http://finance.yahoo.com/q;\_ylt=Al7he7j4xkWAM99.PPB7UVFO7sMF;\_ylu=X3oDMTE5cnE2OWVuBHBvcwMzBHNlYwNtYXJrZXRTdW1tYXJ5SW5kaWNlcwRzbGsDbmFzZGFx?s=^IXIC" >Nasdaq</a></td><td><span class="streaming-datum" id="yfs_l10_^ixic">2,147.35</span></td><td class="ticker_down"><span class="streaming-datum" id="yfs_c10_^ixic">-31.65</span></td><td class="right_cell ticker_down"><span class="streaming-datum" id="yfs_pp0_^ixic">-1.45%</span> how do i extract the value example 2,147.35 and -31.65 of NASDAQ

Hi all, i am very very new to c++ hope u guys can pardon me. I have a file called "newclass.h" which declares a few methods.

//newclass.h, the specification file for the class NewClass

#ifndef _NEWCLASS_H
#define _NEWCLASS_H
#include <string>

using namespace std;

class NewClass {
public:

string symbol; //variable to store the symbol (e.g.: Nasdaq)
double lastTrade; //variable to store the last traded value
double changeValue(); //variable to store the change in value
double changePercentage(); //variable to store the change in percentage

//function to get the respective values
//the word const at the end of the member functions specify that these functions cannot modify the member variables of a variable
void getDow(string symbol, double, double, double) const;
void getNasdaq(string symbol, double, double, double) const;
void getSP_500(string symbol, double, double, double) const;
void getFTSE_100(string symbol, double, double, double) const;
void getDAX(string symbol, double, double, double) const;
void getNikkei_225(string symbol, double, double, double) const;
void getHang_Seng(string symbol, double, double, double) const;
void getStraits_Times_Index(string symbol, double, double, double) const;
};
#endif

and the other file i have is "newclass.cpp"

//newclass.cpp, the implementation file
#include #include "newclass.h"

using namespace std;

how do i continue writing the main function of the method in newclass.cpp thanks

hi, i got a database table that have 4 column id,subject,contents,date the date column is varchar datatype and its the data is DateTime.Now.ToString() How do i select 7 days record from the table.. Select * from announcement WHERE ???? thanks

i have look thru many times.. Do not have the GotFocus event.. Well, i think i create a static method in Form1 and before Form2 closes, it will fire Form1 method instead of using the GotFocus

somehow, my form dont have the GotFocus event

Hi, I got 2 forms.. Form1 and Form2. When the program is executed, Form1 is called. There is a button that will open Form2. At this point of time, Form2 will be on top of Form1. After the user closes Form2, i want form1 to show something.. But i cant find the OnFocus event.. any idea?

Hi, I got this chart object on my UI thread called 'm_ChartControl' I got a method called AddAnnotations that will be run on a new thread in my Form_Load method. Inside my AddAnnotation method there is a line of code that do this. Annotation a = m_ChartControl.Charts[0].AnnotationList.CreateAnnotation(); But m_ChartControl.Charts[0].AnnotationList.CreateAnnotation(); is in the UI thread. How do i create a delegate to put it here? I have tried this.

    private delegate Annotation AddAnnotation();
    AddAnnotation addNewAnnotation;
    private Annotation CreateAnnotation()
    {
        return m\_ChartControl.Charts\[0\].AnnotationList.CreateAnnotation(); 
    }
    void cAnnotation()
    {
        this.Invoke(addNewAnnotation);
    }

I changed this to Annotation a = cAnnotation(); and i get this error Error 18 Cannot implicitly convert type 'void' to 'Manco.Chart.CF.Layout.Annotation'

i have create another Delegate

    private delegate void AddAnnotation();
    AddAnnotation addNewAnnotation;

    private void CreateAnnotation()
    {
        m\_ChartControl.Charts\[0\].AnnotationList.CreateAnnotation(); 
    }
    void cAnnotation()
    {
        this.Invoke(addNewAnnotation);
    }

and under the AddAnnoations method i change it to

anno[countA] = cAnnotation();

and i get this error Error 4 Cannot implicitly convert type 'void' to 'Manco.Chart.CF.Layout.Annotation' i tried change all the void to Annotation but still get error

hmm.. i still get the same error :( could this be the error? under the AddAnnotations method. anno[countA] = m_ChartControl.Charts[0].AnnotationList.CreateAnnotation();

Hi, I get this error despite create a delegate..

    private delegate void ResumeChart();
    ResumeChart ChartResume;

    private void ResumeChartLayout()
    {
        this.m\_ChartControl.ResumeChartLayout();
    }

    void ResetChart()
    {
        this.Invoke(ChartResume);
    }

Inside my constructor I have this.

    public frmGraph(String stockQuote,String\[\] args)
    {
        InitializeComponent();
        newArgs = new String\[args.Length\];
        Array.Copy(args, newArgs, args.Length);
        token = newArgs\[0\];
        
        this.stockQuote = stockQuote;
        //this.stockQuote = "MGM";
        label1.Text = stockQuote;
        this.Text = stockQuote + " Graph";
        **ChartResume = ResumeChartLayout;**
    }

Inside my form load, i create a new thread to call another function

    private void frmGraph\_Load(object sender, EventArgs e)
    {   
        FillDataTable();

        //SetFilter(DateTime.Now.AddDays(-9), DateTime.Now);
        m\_ChartControl.Charts\[0\].Data = this.GenareteDataForCandle();
        m\_ChartControl.SuspendChartLayout();
        m\_ChartControl.LoadTheme("Manco.Chart.CF.Theme.xml");
        m\_ChartControl.Charts\[0\].ChartType = ChartType.Line;

        m\_ChartControl.Charts\[0\].ValueAxisList\[0\].Min = this.m\_dStokMin;
        m\_ChartControl.Charts\[0\].ValueAxisList\[0\].Max = this.m\_dStokMax;

        **workerThread2 = new Thread(new ThreadStart(AddAnnotations));
        workerThread2.Start();**

        m\_ChartControl.ResumeChartLayout();
    }

This is my AddAnnotation function that will invoke the ResetChart() method

    public void AddAnnotations()
    {
        string toa = "calls";
        Annotation\[\] anno = null;
        int countA = 0;
        int arrayIndex = 0;
        while (true)
        {

            XmlDocument xmlPlogs = getAllPlogs(toa);
            XmlNodeList plogs = xmlPlogs.SelectNodes("/PlogList/Plog");

            foreach (XmlNode plog in plogs)
            {
                XmlNodeList receivers = plog.SelectNodes("PlogUnique/Message/Receiver");
                
                foreach (DateTime dt in dateArray)
                {
                    DateTime newDT = Convert.ToDateTime(plog.SelectSingleNode("PlogCommon/T

well.. basically this is wat i am foreaching

    public void AddAnnotations()
    {
        string toa = "calls";
        while (true)
        {

            XmlDocument xmlPlogs = getAllPlogs(toa);
            XmlNodeList plogs = xmlPlogs.SelectNodes("/PlogList/Plog");

            Annotation\[\] anno = null;
            int countA = 0;
            int arrayIndex = 0;
            foreach (XmlNode plog in plogs)
            {
                XmlNodeList receivers = plog.SelectNodes("PlogUnique/Message/Receiver");

                foreach (DateTime dt in dateArray)
                {
                    DateTime newDT = Convert.ToDateTime(plog.SelectSingleNode("PlogCommon/TimeOfOccurrence").InnerText);
                    newDT = Convert.ToDateTime(newDT.ToString("dd MMM"));
                    String content = plog.SelectSingleNode("PlogUnique/Message/Content").InnerText;
                    if((content.Contains(stockQuote)) && (newDT.ToString() == dt.ToString()))
                    {
                        for (int i = 0; i < dateArray.Length; i++)
                        {
                            if (dateArray\[i\] == newDT)
                            {
                                arrayIndex = i;
                            }
                        }
                        anno\[countA\] = m\_ChartControl.Charts\[0\].AnnotationList.CreateAnnotation();
                        anno\[countA\].Location.TypeX = LengthType.Bound;
                        anno\[countA\].Location.X = arrayIndex;
                        anno\[countA\].Location.TypeY = LengthType.Bound;
                        anno\[countA\].Location.Y = 0;

                        anno\[countA\].Data = "     ";
                        anno\[countA\].Font.Size = 4;
                        anno\[countA\].Font.Bold = false;
                        anno\[countA\].Color = Color.FromArgb(1, 1, 1);

                        modulePath = this.GetType().Module.FullyQualifiedName;
                        moduleDir = Path.GetDirectoryName(modulePath);
                        anno\[countA\].ImageFile = Path.Combine(moduleDir, "ArrUp.png");
                        countA++;
                    }
                    
                }
            }
            Thread.Sleep(5 \* 60 \* 1000);
            ResetChart();
        }

hmm now i get this error Error 21 'System.Collections.Generic.IEnumerable<Manco.Chart.CF.Layout.Annotation>' does not contain a definition for 'Add' and no extension method 'Add' accepting a first argument of type 'System.Collections.Generic.IEnumerable<Manco.Chart.CF.Layout.Annotation>' could be found (are you missing a using directive or an assembly reference?)

hmm i get this error Error 21 Cannot implicitly convert type 'Manco.Chart.CF.Layout.Annotation' to 'System.Collections.IEnumerable'. An explicit conversion exists (are you missing a cast?) I tried doing this also cant work IEnumberable anno = m_ChartControl.Charts[0].AnnotationList.CreateAnnotation();

could you give me a little sample of using IEnumerable in my above code? thanks

actually this is the code i want to run inside the foreach loop

        // Add annotation to the line chart.
        Annotation aonnotation = m\_ChartControl.Charts\[0\].AnnotationList.CreateAnnotation();

        // Bind annotation to the first category in the last series (Volume).
        // X coordinate is category
        // Y coordinate is series
        aonnotation.Location.TypeX = LengthType.Bound;
        aonnotation.Location.X = 6;
        aonnotation.Location.TypeY = LengthType.Bound;
        aonnotation.Location.Y = 0;

        // Set annotation properties
        aonnotation.Data = "     ";
        aonnotation.Font.Size = 4;
        aonnotation.Font.Bold = false;
        aonnotation.Color = Color.FromArgb(1, 1, 1);

        modulePath = this.GetType().Module.FullyQualifiedName;
        moduleDir = Path.GetDirectoryName(modulePath);
        aonnotation.ImageFile = Path.Combine(moduleDir, "ArrUp.png");

This code will be create in each loop, but i cannot use the same variable name aonnotation because i need different name to generate annotations onto my chart.
