C++ :: Play Sound On Key Press - Stops Working After A Few Seconds
Sep 15, 2012
I'm making an apllication which needs to play .wav file when user type something inside QTextEdit. I made some code but after minute or less the sound stops, so I made silly workarround. After 30 clicks I invoke sound->stop(); and then the loop start again, that works, but it's not good, can you give better solution. Here is my code:
Just using Find in my source code to look for variables or whatever, works once or twice then just stops - Doesn't find anything even if it's there. If I restart VS it works again, but not for long.
I'm having troubles with this program I made. Put it simply, it's a basic program using Queues. Whenever I try to input a value, my compiler(Dev C) suddenly stops working. The .exe file crashes and I've no way on how I can execute my program.
Code : #include<iostream> using namespace std; int *queue; int rear, front, queueSize; void enqueue(); void dequeue(); void display();
I want to convert seconds into hours, min and seconds. I was able to test it with a small equation turning seconds into hours but now it returns zeros for every entry.
Code: #include <stdio.h> void secCount(int *seconds, int *hours, int *min, int *sec); int main(int argc, const char * argv[]) { int sec=0, hours=0, min=0, seconds =0;
I want to make my computer beep, when a specific file I have already created changes. The idea is this:
I have a personalized e-mail for my website.
When people send me a message, I don't know what happens at all, but at least I can create a file which leaves the comment there. How can I make a program to beep when a file changes?
I code login form. In the textbox I want to clear if there are some text or close form if there's nothing. The problem is System beep sound occured when the text is cleared. Here's my code
When I use the following handler to handle and mix multiple channels, I get about 1 time unit sound, 5/6 time units silence.
//The volume conversion! #define VOLUME_PER_SOUND(volume) ((SDL_MIX_MAXVOLUME / 2)*volume) //Ammount of times to multiply the buffer! #define MULTIPLIER_BUFFER 1 /* This function is called by SDL whenever the sound card needs more samples to play. It might be called from a separate thread, so we should be careful what we touch. */ void SDLAudioCallback(void *user_data, Uint8 *audio, int length) {
[code]....
(I'm working with 44.1kHz stereo PCM streams)... I've multiplied the stream some times, but to no effect (see the c<MULTIPLIER_BUFFER loop arround the mixing)...
As I was testing it, the program suddenly stopped giving an output. Here is the code:
#include <iostream> using namespace std;
int main() { cout << "Ten people ate breakfast with you this morning. Each of them " << "had pancakes. Please enter how many pancakes each of the ten people " << "ate. " << endl;

The while loop after int glutton does not work and seems to stop the program. I replaced the "glutton" in the cout with "testing testing" and it still did not work. However, when I commented out the loop, it appeared. Finally, it can't be what's inside the loop, because I commented that out too, and it still didn't work.
the program is of an address book. the syntax is all fine, and the initial menu of options does show up. but once you punch in the cin, the program just stops.
I am currently working on a c++ project that will input students and process their grades. I encountered a problem and my code stops executing after the getScores function. Im not sure what the problem is, but im guessing its something within the function and the loops.
//Name: getScores //Description: Will get scores for student //Parameters: None //Return: testScore double getScores()
I am trying to transform seconds into HH:MM:SS. I thought it would be easy using the TimeSpan functions however my hours exceed 24 hours now and then therefor it is not viable for use.
private string getFormattedTimeFromSecond(double second) { TimeSpan t = TimeSpan.FromSeconds( second ); string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s", t.Hours, t.Minutes, t.Seconds); }
This is what I have tried, however it does not like it much when hours exceed 24.
I have a code to check the last time modification of a file using "gmtime". Is it possible to remove the seconds in the result?
Here is my code:
struct tm* clock;// create a time structure struct stat attrib;// create a file attribute structure stat("test.txt", &attrib);// get the attributes of afile.txt clock = gmtime(&(attrib.st_mtime));// Get the last modified time and put it into the time structure
I am trying to write a program that will display a table with "seconds" and "Distance". Where Seconds goes from 1-12 and the distance is displayed according to each second. However I am having trouble getting the distance variable to display any values. By the way I am also using a second function in this program besides main(), called FallingDistance(). Below is my code for the program so far.
#include <iostream> using namespace std; double FallingDistance(int, double); int main() { int Seconds; double Distance=0; int distance;
I need to get the current time, have the system sleep for a period of time, then return the difference in seconds.
#include <iostream> #include <string> #include <ctime> #include <time.h> #define _CRT_SECURE_NO_WARNINGS using namespace::std; // in the <ctime> library is a function time(0)
[Code] ....
I'm not receiving an errors but the return value is not correct. It's returning 1.4259 no matter how long it sleeps for.
i create a structure called time. Its three members, all type int called hours, minutes, and seconds. This is in 12:59:59 format and i finally want to print out the total number of seconds represented by this time value.
long totalsecs = t1.hours*3600 + t1.minutes*60 + t1.seconds
I have to program something that would convert miles per hour to seconds per mile.
I'm having an issue with something that I coded. Lines 21-23 are not showing up when I compile the program. What I'm trying to do is convert seconds into minutes.
What I have so far is
#include <iostream> using namespace std; int main() { double miles_per_hour, minutes_per_hour, seconds_per_hour, seconds, minutes; cout << "Enter the miles per hour: "; cin >> miles_per_hour;
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO; using System.IO.Ports;

How to pick date / time when serial port starts reading , and also when reading stops ?
I am looking for a function or any example that shows elapsed time in seconds and minutes. I didn't find any solution for both OS Win and Linux. I am looking for example that works for both - win and linux.
I know there has to be a system call to pause (not system("pause") execution of a program for a few seconds. I would like to give the illusion that my program is 'thinking' rather than just spit out the result as soon as the user has hit the enter key.
