Just a quick newbie question: I'm doing a console application and whenever I open a .exe using system(), the console pauses and does not run the next instruction until I close this exe. For example when I do this:
...
system("mspaint.exe");
printf("Hello");
It opens ms paint and does not print the next message until Paint is closed. How do I work around this?
I am trying to display a messagebox, but instead of just displaying the message box, there is also a console the pops up. How do I prevent the console from popping up? I'm using Visual Studio 2012. I'm creating an empty project, but I still get the console.
I'm working on an assignment that's supposed to open a text file, read the first 24 lines and then pause if there are more than 24 lines and wait for the user to hit enter for every 24 lines. my text file has 27 lines and each line is just a number 1-27. My program isn't stopping at 24, it's going all the way to 27 but when it's displaying the contents it shows the numbers 5-27.
#include <iostream> #include <string> #include <fstream> using namespace std; int main() { fstream file; string name;
[code]....
I've got the cin.get(); in hopes to pause the program after 24 but it's obviously not working
I'm new to C programming and am quiet lost, create a program that takes a start and stop time and prints the passed, or show me where I can find the information needed?
I'm trying to get the user to input their 5 digit zip code but my problem is how can I stop the program after the five characters have been inputted. Also how can I only get numbers to be inputted cause so far letters can be inputted as well.
The glucometer stores the tests and the code just pulls the most recent one, however even if I unplug the glucometer the first if statement keeps repeating and the LED in pin 12 keeps shining. Is it the if statement itself malfunctioning, or is the Arduino storing the data it pulled and just repeatedly plugging that into the if loop?
double number = 10000000; int range;//the length of the string result string result;//holds the number in a string ostringstream convert; //stream used for the conversion convert << number; result = convert.str();
range = result.length();
I'm trying to convert a double to a string and when the number goes to ten million it goes to scientific notation and it shows it in the string. How do I stop it from do that?
You are to write a program that will allow a user to enter infinite numbers (greater than zero)(One number at a time). You must have a way for the user to stop entering values.Once the user stops, you will immediately display the following:
The lowest number entered is: The highest number entered is: The number of values entered is: The average of the numbers entered is: */
main() { int userNumber=0, sum=0, count=0, highNum=0, lowNum=0, lastNum = 0; double average; printf("Enter a number greater than 0: (Enter -1 to stop) "); scanf_s("%i", &userNumber);
[Code]....
My program outputs everything I need except the lowest number entered. I have been spending a considerable amount of time on this problem to no avail.
This is a problem I have been having with every program I write since I started using SDL 2. Whenever I compile my code and run my program, everything works perfectly fine until at some point (usually after 3-8 minutes of running), the program will stop responding completely and I will have to exit out of the console to close it. The code I believe is relevant is:
void MainLoop() { InitLoop(); while ( !QuitMain )
[Code].....
If I change SDL_PollEvent(&Event) to SDL_WaitEventTimeout(&Event,100), then the problem goes away (I did that and had the program running for about an hour without it stop responding before I decided that it solved the problem), so I believe that the problem has something to do with event handling. Also, it might be noteworthy to mention that when I use SDL_WaitEventTimeout with the second parameter being a small number (because 100 milliseconds is a long time to wait and makes the program run at like 8 FPS), the problem returns.
My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.
I am new to c++ programming, and I wrote this program. It runs perfectly but the problem is I want the program to stop If I entered letters other than A,B or C
The code as follows:
#include <cstdlib> #include <iostream> #include <cstring> #include <iomanip> using namespace std ; int main() { // Deceleration Statements
When my program is working with a big list, it always connects to the internet and checks information from a website. It is going fast, but when I'm trying to update a label on every connection, it just shows at the end, when everything is checked. Progressbar value is updating. How to solve this?
using namespace System; ref class A { public: A(){Console::WriteLine(L"A constructor");} virtual void func(){foo();} void foo()
[Code] .....
Supposing that class A is the development code; and so for unit-testing purpose I create a mock for it. But I don't know how to override A's constructor such that it will not get executed in my unit-test code.
I have a simple UDP client that should be able to send and receive packets. It does its job, however if there are no packets received for a while it stops listening for any new packets and I'm not sure what's causing it.
I wondering how to stop a infinite loop. The program clears a file then opens it and refreshes it over and over(the file is going to be modified by another program). I want it to start from the beginning anytime i press enter or escape, it doesn't really matter as long as you can restart it.
It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h> // Function prototypes void printBoard(char board[3][3]); int main() { int quit = 0; // Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
i am tring to update a sql database table, first i select the values from database after it i display them into text boxes and drop dwon lists.and then i make required changes to values but when i click on update button the page is post backed and all values are set as they were already in database.
My question is how the button click mull ti times on page load in C# windows form??because in my project i am working on video for LAN based Skype in which i use 2 pictures boxes one for capture images and another for display .. so i want that on page load picture box capture images until i stop it .. following is my code :
