When you press a key it automatically delays a bit then starts repeating without delay.
The second key pressed action comes with a delay and i want it to start repeating without delay. And could not find anything useful.
I might not be able to tell what i want exactly. Ok press simply a key and don't release it in a text editor. You will realize a delay at second character showing up.
for example i have
int count = t1;
while(count>counter){
Sleep(delay);
Int32::TryParse(textBox2->Text,add);
result = result + add;
counter = counter + 1;
Problem is that sleep stops all program for specified time, Is there an alternative to sleep that would only stop part of code or can i use sleep different way to specify what it pauses?
So I'm in the process of building my 2D game in Allegro5, I'm building a side platform game and at the moment I have a sprite being able to walk left right and jump. What I want to do is put a time delay on the jump function so that when a user presses the jump button and the sprite has carried out the jump function I want there to be a 1 or so second delay before the jump button actually carries out the jump function again.
I have quite a bit of code so not sure what bits to place in here, I'm more looking for a way of doing this, so providing me code isnt really needed just a way it can be done.
Things that might be useful to know:
At the moment I have a timer initialized in allegro which is used with my FPS int to mean that my game runs at 60FPS.
I have a bool bIsOnGround which maybe could be used into this, I'm not sure...
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)...
How can i play a mp3 file in the background?How can i rule the volume of the mp3 file?why does delay(0.25) doesnt work in this code?
Code:
FILE *datei;
char line[ANZAHL][LAENGE];
int i ;
datei = fopen ("song.txt", "r");
if (datei != NULL){
for(i = 0; i < ANZAHL;i++) {
delay(0.25);
fgets(line,LAENGE,datei);
printf ("%s

I want to calculate the total some of delay pf receiving Side Packet . Code is as Follow ..
What is weird that even if i invoke a sleep of 2 sec ,than its show delay always zero. Delay will be in microsec ..Is there any problem with logic or anything else..
Code:
do
{#pragma omp parallel private(nthreads, tid) {
/* Obtain thread number */
tid = omp_get_thread_num();
if (tid == 0) {
nthreads = omp_get_num_threads();

My code is given below:
cout<<"1. runtim";
cout<<"2.tims";
cout<<"Your selection will be automatically neglected within (function to be inserted for time ) ";/* insert timer here */
cout<<"What kind of process u need to do";
.
.
.
.
I have 2 questions
1.the timer function has to be such that when any key is pressed in between the specified time its has to stop its counting and go to the nest line and functions . i checked sleep function but if any key is pressed its does not break out of the sleep program and execute the next command
2.and if the timer has completely finished running then it has to skip few lines and execute the program .
#include <iostream>
#include <windows.h>
#include <conio.h>
#include <ctype.h>

When I press the up key it will not display anything.
I already tried getchar(); but it doesn't worked the program skips this command
View 2 Replies View RelatedI have a program that I made, which does a list of stuff, then checks if a key is pressed, and if it's pressed, stop the looping.
The problem is, it checks if the key is pressed once a loop, which means that if the list has delays, you have to hold the button down for a while (depending on the list).
Here's an example:
Move mouse;
Pause program for 2 seconds;
Move mouse;
Pause program for 2 seconds;
Check if key is pressed;
What ways can I fix this problem?
I am altering this program to include some alterations for a class. When I run it with start without debugging, it just skips to press any key to continue. It will not display the cout << "Volume of box1 = " <<boxVolume1.

View 2 Replies View RelatedI have a problem where I need to add the ability to input numbers into a calculator program through either a form button press or keyboard press. I have the button press working fine though I can't seem to get the program to start with the cursor active in the textbox for keyboard input. I've use this.ActiveControl = result; "result" being the textbox. Though the issue here is the program starts off with the cursor active but only for the first instance of keyboard inputs.
Perhaps its the way I wrote the program but is there a way I can achieve this? I found a way to write this calc by having a single event for all button presses, opposed from an event for 1-9. Not sure if this is a good approach but here is some of the code.
private double num = 0;
private string calculate;
bool pressed = false;
private void button_Click(object sender, EventArgs e) {
if ((result.Text == "0")||(pressed == true)) {

I'm trying to implement this on ubuntu, to compile and run only under ubuntu.
I found 100s of other attempts at answering the general question of arrow key press in c++. Nothing solid.
Some recommend using the Readline for the functionality I am trying to implement, but I need to stay clear of GNU licences if I can for this project. And some tips only work on projects for windows machines... for example the conio library.
For linux there may be the option of using the ncurses library which I will take a look at, but I am stubborn and want to implement this myself. It should be an easy straight forward thing to do, which is why I am a bit frustrated at the moment.
Here is my test code so far.
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] ....
So! This works... 80% of the problem is solved. If you compile this, g++ under linux, ubuntu in my case, and run. Each keystroke reveals the correct key numbers.
q=113
w=119
when I click on the up key I get,
up = 279165
I thought, I can use this number is a if(int == '279165') to detect the up key.
I was not so lucky... this int is not behaving like an int!
So I modified the code to see it I could carry out an int operation on this number.
I added a 100000 to int i.
cout<< i + 100000;
Code:
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] .....
Compiling and running this, and pressing the UP key gives the following number.
100027100091100065
Some some sort of array, something like, [27][91][65].
I tried all ways to access these individual numbers, actually the third one for comparison purposes, but no luck.
For completeness sake I list the other arrows.
UP = [27][91][65]
DOWN = [27][91][66]
LEFT = [27][91][68]
RIGHT = [27][91][67]
A little further digging shows that these numbers are derived from the representation of a "multi-char" constant, the data type given when pressing special characters...
Now here is the main problem I have, I can find ANY decent documentation on how to handle and play with "multi-char" .
My problem is , i want to make a simple calculator , in the console i want afterall the user to choose what type of operation he want pressing a key like i mentioned in the title the keys would be F1,F2,F3 , i'm not finding in the internet the code to the detection of a press key like what i want.
Code:
#include <iostream>
using namespace std;
int F1 (int x, int y) {
cout << "Enter a number: " << endl;
cin >> x;

I would like to know how to press a key as if it had been pressed on the keyboard in a program. I would also like to know how to read input from a xbox 360 controller. I want to know how to do this so that I can add joystick support to a few mmos that I play that do not already have it.
BTW I am using C 99
I have been trying to make a small program that I will be using in a larger program that will make the user press space to see the next line of output.
Not exactly sure what I'm doing wrong, but I'm pretty sure that I need to put the space that the user would enter into an output file, and the read the input file
It runs, but it doesn't allow me press space before showing the next line.
I added a getline(cin, charVar) before, but I got a whole bunch of errors.
#include <iostream>
#include <string>
#include <cctype>

When the user gives no input, they have to press enter twice before "Done." is printed.
cout << "What do you want the name of your page to be? ";
std::getline(cin, pageTitle);
if (cin.get() == '
')
pageTitle = "Welcome to Website.";
cout << "Done.
";
Is there a way to print "Done." after pressing enter once?
I would like to have my program pause at a certain screen but not to have the "Press any key to continue..." message or the press of a button. In my program, the code looks similar to this:
for(;;)
{
cout
cin
cout
cin
...
//
here, I want to have a pause to view what the for loop has come up with but to not have a message display or a button press needed. At the end of the loop, I want it to pause before looping again. IS this possible?
If so, how can I implement it into my program?
i changed my code from release to debug mode. when i try to debug it shows a dialog box that '... does not contain debug information press ok to continue"..

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:
Code:
int count = 0;
bool MainWindow::eventFilter(QObject *o, QEvent *e){
if(e->type() == QEvent::KeyPress)
{
tipka->play();
tipka->seek(0);

I am using Windows 7 32bit OS and want to detect the CPU power button press event in my console application developing in C language.
I configured the power button setting to "Do Nothing" which is in "Choose what the power button does" options in Control Panel->Hardware and Sound->Power Options. So now i want to detect this power button press event and do some processing in my application then i will initate shut down from application itself. Looking for windows API details which will detect the power button press event.
So I have been assigned a program that counts keystrokes, alphabetical characters, and vowels. I have the program working as desired but I just can't figure out how to make it end upon ONLY the "return" key being pressed.
