1. I want to do 2 while at the same moment. Exactly I want one while which is checking the time and it should di something every X second and the other should check something parallel.
2. How i can write the program what i write automaticly into the autorun on every windows pc.
3. Can i change the process-name when the programm started?
4. Can i save my .exe under another name in the autorun
I'm new to C++ programming and only have a little java experience but I'm trying to learn some C++. I want to create a simple contour plot from scratch, and I see that there are many programs online, but what I haven't found are the basic components to a contour plot! I know that I have to make some kind of grid, I need to identify/set levels, etc.
I want to write RPC program in C for matrix multiplication - My question is that during serialization & deserialization process ,what shall I keep in mind? I recently got an error "call failed: RPC: Can't decode result " ,what this means?
My program is simply send an array A and return 3*A.
I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.
What I have: A basic program for infinitely looping after and testing for an active process. It has a delay system built in to make it so it is not constantly iterating.
What I need: A way to get process IDs from other Processes other than my program. With a way to use that ID to detect if that process is active on the computer or not.
Parts of my code that need changing:
/* Code for handling the process would go here */
/* Code for detecting the target would go here */
What the goal of my program is: Perform operations to terminate the process of cmd.exe when it is active on the user's computer. Then output the status of the process and the time it took to find that process to the user.
It contained functions that I needed, but I need more information on how to apply them to other processes instead of the parent of my program and its' children.
The brief is to write a program that implements a musically-interesting or musically-useful audio effect/process in C without external libraries other than those prescribed (PortMedia/PortMIDI/PortSMF/PortAudio, Libsndfile).
I have a current assignment for C++ involving us to make a program to determine coin change for example if you input the number 127 you would need 2 half dollars 1quarter and 2 pennies I have no way how to program this.
This is my code that doesn't do what i want it to
#include <iostream> using namespace std; int main ( ) { float change; int half_dollars, quarters, dimes, nickels, pennies; // declare variables
the problem and my code is at the bottom, the thing is when i checked out what my change was, it was it was like -14.23 which is werid.
Write a program that determines the change that the user should receive after having paid for their purchase. Your program
prompts the user for the number of items purchased accepts the number of items purchased prompts the user for the unit price of each item accepts the unit price of each item calculates the total purchase price, including HST outputs the total purchase price prompts the user for the cash tendered accepts the amount of cash tendered calculates the change owed to the user outputs the number of loonies in the change outputs the number of cents in the change
You may assume that the user enters valid amounts and tenders enough cash to cover the total purchase price.
The output from your program looks something like:
Enter the number of items : 4 Enter the unit price : 3.15 Purchase price 12.60 HST (13%) 1.64 Total price 14.24 Cash tendered 20.00 Change loonies 5 Change cents 76
Alright so I'm in a computer programming class and I was given the following problem..Write a problem that takes an integer value and multiplies each of the digits together. 4 digit numbers only.
IE; What number do you want to process? 2684 Starting number 2684 End result 384
I know how to start the begging of the program, but i dont understand how to have it to where you can type in all four digits and then it will multiply each number by the other. Also, what are some ways to change the color scheme of the program? I know how it works using CMD, but in Visual C++ its totally different aha.
And for some reason my program pauses (nothing displays, and my cursor changes to the little "loading" cursor thingy) when it hits line 139. That is where I added an additional piece of code that should change the shape of the triangle while the program is running.
My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code: #include<iostream> #include<algorithm> #include<vector> using namespace std; void change(double cents, int a[]); int main() { double Dollars; double cents;
I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
I have app that has while true on input listening to changes and then in some condition needs to open simple gtk app, and afterwards continue listening.
I thought that i could fork gtk part, and kill it when it is not needed.
But am not finding much examples on internet. 2 processes dont share data. Can child process start a gui app? And is this a good approach.
I am looking for a way to run a process form memory, without having any executable. The application will be kept inside a resource and will be extracted during run time. It should be then started as a new process. I couldn't find a solution that works also on x64
I need my Unix program to generate a directory with a format like this: "hinesro.<pid>". I have some code that mostly works, except for the directory ends up with a question mark on the end, like this: "hinesro.12345?". I need it to just display the directory without this question mark. Here is my code:
Code:
// Using headers sys/types.h, sys/stat.h, unistd.h, and stdio.h int pid = getpid(); char prefix[] = "hinesro."; char fileName[0]; sprintf(fileName, "%s%d ", prefix, pid);
i have read that inheritance slows down the process.because a_class -> b_class -> c_class it goes thorough many classes to find a function or a value. people advices not to do it more than a few times. what if instead of inheritance we are using headers, would it slow down the process also??i mean which one is faster? and arent both the same when we use headers or used inheritance.
I am looking into how to create zombie process. They are created when parent process don't call wait() and hence they are not removed from the process table. How do I create zombie process in C++? What part of the code when missed, make a process/thread zombie? Is it the pthread_join()?
Am developing windows forms application where in my form am fetching data into list from some object which takes around 2 minutes to complete processing so meantime i want to show progress bar before starting process till it ends with percentage. I have return a code to do multitasking but it is throwing error as "Cross-thread operation not valid: Control 'listOrg' accessed from a thread other than the thread it was created on".
private void btnOrg_Click(object sender, EventArgs e) { try { // To report progress from the background worker we need to set this property backgroundWorker1.WorkerReportsProgress = true;
I would like to ask about editing proccess memory.For example,I would like to create some program for a multiplayer game which I play.How do I work with memory adresses and what are commands for it.
I was given an assignment where I have to input two points (four integers) on a Cartesian plane from a file and then process it using functions. My professor is very particular so the comments are a bit excessive, but here's what I have.
double radiusFn(double, double, double, double);//4 double values, one for each point. All points are needed for the calculation of distance in this function. double diameterFn(double);//Only uses one double value - the radius. Both functions below use the same value. double circumferenceFn(double); double areaFn(double); int main() {
how I can run this as a separate process from the parent program, like a child process,
and return the result back to the parent program.
this script is as follows.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then print "started" if file "/Stuff/t" does not exists, then print "stopped"
if file "/Stuff/s" does not exist then print "quit" and then quit.
I think my linker needs an additional #include to be able to deal with int& anterior and int& posterior. I'm not sure as I'm new to C++. My version of Dev-C++ is Orwell V5.8.3.
