Nov 15, 2013I was assigned a project to implement a real time graph to an application which continuously outputs data numerically through the GUI. The application that was created to do this is written in C.
I have to turn those numerical numbers into a graphical display that is periodically updated to appear as real time.
My adviser suggested using NTgraph [URL] ...... I had no clue how to implement this to my code and was finally able to understand that the .OCX needs to be registered as a COM and then imported to the application using visual studios. However, I get an error when I try importing it since it is in C (Visual Studios 8) and not an MFC application.
So my question is if it would be possible to implement the ActiveX control to my application even though it is not an MFC application and how to go about it.
C++ :: Publish Data Over The Internet In Peer To Peer Style Communication?
Sep 24, 2012I need to be able to publish data between multiple machines at remote locations. I have been able to send data between two machines on a network in the same room. However, how to begin with resolving IPs for machines on other networks that are miles away etc. I would assume the application would need to LISTEN & PUBLISH in order to achieve this?
I have also googled this, and can only seem to find C# examples, and they seem to be for data between remote computers on the same network... What I need is to be able to find some guidance on sending data between me and someone who I previously had no knowledge of. I know this must be possible due to the fact that p-2-p chat clients exist, and that p-2-p file sharing exists.

C :: How To Generate Real Number Between 0 And 1
Mar 1, 2015I am a very very beginner at programming with C. Well, basically i have to generate a real number between 0 and 1 (which as the same as from 0 to 100 k and than dividing everything with 100 k).
Why I am constantly talking about 100 k? Because I would need approx 50 000 random numbers between 0 and 1. My code currently looks something like this:
Code:
int main(int argc, char** argv) { int min,max;
double number;
srand((unsigned)time(NULL));
number = 1 + rand()%100;
printf("The number is: %lf",number);
sleep(2);
return (EXIT_SUCCESS);
}
And If I am not mistaken, should generate numbers between 0 and 100. But I can't figure it out how to change to code in order to get enough numbers.

C/C++ :: Check If Quartic Has Real Roots?
Feb 7, 2015I have been writing code to find the roots of a quartic (with coefficients input by the user) by the Newton Rapson method. The method fails if no real roots exist so I have been trying to implement an initial check to see whether the equation has real roots. I've been trying to use the intermediate value theorem but it only works for functions with a positive and negative tail. extend the bounds (fa and fb) to check over many ranges or any other mathematical method of better effect?
Atm I define fa<0<fb where fa=F(-10) and fb=F(10).
#include <stdio.h>
#include <math.h>
#include <conio.h>
#include <stdlib.h>
int a0, a1, a2, a3, a4;
double F(double x) //Sets main function {
return (a0+a1*x+a2*pow(x, 2)+a3*pow(x, 3)+a4*pow(x, 4));

C++ :: Program To Find Smallest Real Factor Of A Number
Oct 10, 2013I need codes for a program in C or C++ that will show the real factor (the smallest one, without the number 1) when an integer is given as input.
When the program is started, it will ask to enter a number and press enter. After entering a number, it will first check if it is a prime number or not. If prime, it will notice that it is a prime number, otherwise, it will print the smallest real factor of the given integer.
For example, if 12 is entered, it will print, the smallest real factor for this number is: 2
If 27 is entered, it will print, the smallest real factor for this number is: 3
...and so on
C :: Generate Pseudo Random Real Number From Interval (0,1)
Feb 6, 2013How can I generate a pseudo-random real number from interval [0,1] ?
Can it be generalized to any interval? Like [0,a], where 'a' is a parameter?
I tried searching for it, I only found rand(), srand(), random(1), and randomize. None of it actually seems to work for me..
Later I actually succeeded with something like
srand( (unsigned)time( NULL ) );
printf( " %6d
", rand() );
but it only produces up to five digits integers and I cannot divide by 99999 to get it into [0,1].

Visual C++ :: Internet Explorer Displays Blank Page When Opening Local File While Screen Is Off?
Apr 28, 2015I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.
I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):
Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);
This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)
This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)
So I started looking into it:
1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.
2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.
3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.
And why is IE showing a blank page only when computer is running unattended?

C :: Function To Round A Number To Give Integer Number That Is Closer To Real Value

I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.
C++ :: How To Use Time For Time Based Movement
May 1, 2013So I'm trying to learn how to use time for time based movement and what not. I did this only knowing the command time(&variable)
time_t timer;
int I, X;
void main() {
time(&timer);
X=timer;
while(I==5) {
[Code] ......
There's probably some other better way to do it... Obviously but for now I see it as putting current time in X.
start while
take in time constantly until I is 5
constantly asking is time>X(preset time 5 seconds ahead)
if it is
display message and add one to I
Why doesn't this display my message after 5 seconds?
