The only language I know so far is C. Is there any way I can use c programming to display a live chart for a price graph including volume in different time intervals that I want to select. I want it to look like this URL....

View 1 Replies View RelatedI'm working on an app which monitors user selected data sets from various devices, and I'd like to display the data in a CListCtrl. This would be very convenient, but I'm just a little concerned about (1) just how fast can a CListCtrl be populated, and (2) how can i reduce or eliminate screen flicker. To be specific...
1. There will likely be upwards of 100 rows of data, maybe more (probably 5 or 6 columns), and I'm going to have to refresh it all as quickly as possible, perhaps as fast as once per second. I can play games and only refresh a visible rectangle, but how responsive the control would be, having all that data deleted and refreshed continually?
2. You can see why I'd be worried about screen flicker, and I thought I'd likely have to make two identical overlapped controls so I could double buffer as I would with a graphic animation, switching the visibility of one or another control after its updated to give the appearance of sudden complete updates. BUT... I see there is an extended style you can set called "LVS_EX_DOUBLEBUFFER"
I am trying to overlay an image on a live video.I have used alpha blending method to overlay image on the video. On overlaying the image, it gets overlayed five times rather than one as expected.
Both frame data and the image data is taken as BYTE* for overlaying and displaying it.
The image used is a bitmap image.
The data (BYTE*) of both the video and the image is overlayed and the resultant is stored back in the variable of the video and den drawn on the picture control of vc++.
The video resolution is 640x480.
The image I m overlaying is 128x128.
The IDE used is visual studio professional.The code is developed using c++.
How do I overlay the bitmap image as a single image on the live video at a specific position.
I have 2 database. One is on live server and the other on local desktop.

I have the following code. I have hardcoded the x and y values to test. And for some reason for the point (0,-0.5) it plots (1,-0.5) . What is going on, because if you try other values then the graph displays correctly.
foreach (var grp in q) {
point = new DataPoint();
Sum1 = grp.Sum1 > 2 ? 2 : grp.Sum1;
Sum1 = Sum1 < -2 ? -2 : Sum1;

I need to create a line chart that will be universal for every currency. As Y it will display value of currency, as X it will display time when that value was established.
For drawing I think of using Windows.UI.Xaml.Shapes.Line and Windows.UI.Xaml.Controls.Canvas
What I want to get is something like image below but it would have to draw correctly scaled chart for every currency which is the biggest problem(I think it is).
For every currency I will probably have to get minimal and maximal value which will be used to properly scale a chart(I will probably also have to get rendersize of canvas or something).
The user will choose the range of time and then the correct chart must be drawn (For example 04-11-2004 to 11-03-2007)

Code:
struct Book{
char title[100];
char author[100];
int price;
struct Book *nextedition;

struct Book lib[1000]; I'm going to write a function to compute total price of books by a given author including all books which are future editions of his book, even if the author of that future edition is NOT the specified author. title author price nextedition Book1 Author1 25 &lib[2] Book2 Author2 20 NULL Book3 Author3 30 &lib[3] Book4 Author1 35 NULL
For the example above, given the author "Author1", the function should return 90 (=25+30+35), and given the author "Author 3", the function should return 65 (=30+35).
So here's my attempt:
Code:
int totalPrice(char author[100]){
int total=0;
for (i=0; i<numbooks; i++)
if(strcmp(author, lib[i].author==0))

What I'm trying to do is finding the first book in the lib of the specified author using for loop and then let the while loop do the rest. However, it seems the price is over-counted after each iteration of the for loop but I don't know how to fix it.
I have been trying to calculate the bond price given a certain YTM using class method. Since the YTM and bond price are linked with each other(there is another question asking us to calculate the YTM with a given price),we put price and YTM in "private" and others variables in"public". Actually, this is the format given in my assignment.
I used "getvalue" to get the value of YTM, and used YTM in the formula of bond price calculation. However, the output of the price is infinite, while the output of price is right if I used a specific value of YTM(such as 0.05) in the formula. It means that I didn't successfully get right value of YTM.
#include <iostream>
#include <cmath>
using namespace std;
class bond{
public:
bond(){};
