C# :: Chart In Winform Displaying Wrong Point
Nov 11, 2014
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;
[Code] ....
Attached is what is displayed.

I need to make a bar chart with asterisks that looks like this:
Store 1: ******
Store 2: ***
etc.
anyway, right now what I have is:
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
const int STORES = 5;
int sales[STORES], i;
for (i = 0; i < STORES; i++) {
[code].....
It's not displaying asterisks.

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)
It is a windows store project.

So basically, I started out with each wizard == 1 winform, but then I found another way to do it by making the content of each wizard step a user control, then say, on initial deployment, it load usercontrol1, then when i click next, the panel hide usercontrol1 for usercontrol2 and so forth. Would it be feasible to create all usercontrols (all the wizard step) and add them in an array, then i can load them by index?

So I am upgrading the system from 3.5 .NET to 4.5.1 and fixing any bug that I could find. Long story short, I run into an issue that basically tell me it couldn't find the images in the resource file. I figured out a work around, but first I have to set the picture box or background Image in design time to none. I ran into this Properties Windows while changing the value of picturebox for my user control saying: Property value is not valid. Object reference not set to an instance of an object. This usercontrol is taken from another user control from a different project. Basically, we are reusing it.

I have a main WinForm that I want to press a hotkey and show and hide the form. I can press Insert and hide the form and I see its icon in my Win7 task bar but when I press Insert again it doesn't show. Is my coding logic wrong to make it work? Maybe when its hidden the Insert key isn't being 'seen'? Although the code I am using I got somewhere on the internet that says it will work at the app level.
virtual bool PreFilterMessage(Message% m) {
// Detect key down messages.
if (m.Msg == WM_KEYDOWN) {
Keys keyCode = (Keys)((int)m.WParam) & Keys::KeyCode;

This is a round robin execution. with gantt chart. arrival time and burst time. I think there is an error in my formula to get the right answer,i cant resolve it but my program is running. What is the code or the right formula??
#include<stdio.h>
int main(){
int i,j=0,n,time,remain,flag=0,ts;
int sum_wait=0,sum_turnaround=0,at[10],bt[10],rt[10];
int ganttP[50],ganttStartTime[50];
printf("Enter no of Processes : ");
scanf("%d",&n);
remain=n;

Consider the following:
Code:
float foo( float const *bar )
)
{
float temp;
temp = *bar;
...
}
Something I am noticing is that temp right after the assignment to *bar, is not the same value as *bar. This is for a project at work and the code runs on an embedded board with an ARM processor. I've copied the function into a standalone program for both Visual Studio and Code::Blocks and it works correctly there.

I'm writing a program that shows check fees for different amounts of checks. My other fees are showing up right but the .10 cents is not. It's showing up as .08 cents per check when I run the program.
Oh yeah the + 10 is for a $10 fee
Code:
else if (checks < 20 || checks >= 0) {
fee = .10 * checks + 10;
cout<< "Bank service charge for the month is $ " << setprecision(4) << endl;
}

For an assignment I have to create a random array of four integers, and then I have to allow someone to input up to ten guesses to guess the array in the correct order. I also need to be able to display whatever was generated by inputting -1. Finally, after every guess I have to tell the inputter how many of the guessed integers are correct and in the correct position, as well as how many integers are correct but not in the correct position.
So far I've been able to get the random array to generate properly, but inputting negative one has no effect, although if I input it four times in a row I get to my 'lose' condition. Also, it only seems to allow the user to input 4 guesses and not 10 before going straight to the 'lose' condition. I need to get these issues sorted out before I can move on to showing how many guesses are right etc....
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
srand(time (NULL));

I have the following function:
Code:
public static void Des(byte[] key, byte[] inBuf, byte[] outBuf) {
if (key.Length != 8 || inBuf.Length != 8 || outBuf.Length != 8) {
throw new Exception("Des: Buffer or key length incorrect.");
}
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
[Code] ....
I do not get the expected output of
Code: { 0x88, 0xBF, 0x0D, 0xB6, 0xD7, 0x0D, 0xEE, 0x56 }
instead I get
Code: { 0xC6, 0x61, 0x8D, 0x63, 0x0B, 0x39, 0x31, 0xB0 } am I doing something wrong?
I've even tried reversing the byte order of the test data, and I don't get the right result. I've tested the same data using C++ with CryptoPP on Linux, and I get the expected result, but I'm porting this code to run on .Net, and this is my main stoppage in the process at the moment.

My whole code is working but when the results are sent to my phone only the temperature value is reading correct the light value is all jungled up and moisture and pressure values are reading as 0.
Code:

float moistureVal = 0.0;

I recently wanted to create a (yet) simple program that simulates a mouse movement.So far I managed to make the program work. It does move the mouse, click when expected but the problem is the location it does click at.Here's my code:
#include <Windows.h>
#include <stdio.h>
int leftclick (DWORD x, DWORD y);
int main(){
[code]......
The problem now is: I want the program (for testing purposes) to click at (1920, 1080) and (100, 100) afterwards. Now it does click within a specific range. When I use GetCursorPos to retreive the cursors position it differs quite a bit from where I expected the click to be.
a second question I have is: When I declare the following flag (in the code above) the program does use relative coordinates even though it shouldn't.
input.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP;
Where as it works out well when I add a MOUSEEVENTF_MOVE to it.I couldn't find any solution to this in Microsoft MSDN or any other website.

i'm making a for loop for a mini game which required the user to enter the input number.Let say if the user accidently entered a character instead of integer the whole program will go haywire so is there anyway to check for the error and prompt the user to input the data again?Here is the simple program...
for(row=0;row<4;row++)
{
printf("Enter Row%d:",row);
for(col=0;col<4;col++)
{
scanf("%d",&num[row][col]);
}

I have been experimenting with a program that loads WAV file and tries to read 1s and 0s from audio file (binary coded information). So far I got working code, but the problem is that I'm not getting correct data. I do get somewhat similar data. The problem is that I get data that amplifies low amplitudes, so instead some noise and binary data I get lots of noise and hard to recognize binary data. My code is this
#include <stdio.h>
#include <iostream>
#include <math.h>
using namespace std;
// An unsigned char can store 1 Bytes (8bits) of data (0-255)
[Code] .....
This is wav file in binary viewer (after header)
0030 0032
00300035003200320035003A0048004A
004C0049004A00510049004300360038
and translated to decimal
48 50
4853505053587274
7673748173675456
and this is output from "wavosaur" program (and this one is correct)
0.001465
0.001526
0.001465
0.001617
0.001526
0.001526
0.001617
0.001770
0.002197
0.002258
0.002319
0.002228
0.002258
0.002472
0.002228
0.002045
0.001648
0.001709
You can see it's not the same. I do get the same data like I do from binary viewer, but I don't understand how they are translated to amplitude value. ? Where is the catch?
So this is not really question about c++, but about wav file structure and reading data.
