I know there has to be a system call for a pause function. I simply want the program to pause for a few seconds before executing the next line of code. I do NOT want the user to enter a keypress, just pause the output or code execution for a few seconds.
system (pause); waits for keypress right? I just want it to wait 3 seconds before proceeding. I know it should take an argument for milliseconds right? Also, this is for a homework assignment I have already completed, just doll'in it up a bit for extra credit...maybe...
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.
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?
I am trying to add a small function to allow me to pause the game I am making. I measure the time elapsed using the following algorithm:
1. USE ""clock_t begin=clock();"" FOR SYSTEM TIME OF GAME BEGINNING. 2. USE ""cout<<(clock()-begin)/CLOCKS_PER_SEC;"" TO DISPLAY TIME ELAPSED IN SECONDS.
Now, if I want to pause, I would want to subtract the 'paused' time from the total time elapsed.Say,
Then I would do cout<<(clock()-begin-(resume-pause))/CLOCKS_PER_SEC;
This, though is what I want, works only once(I can pause only once). I can use arrays of resume and pause, but it would still limit the number of times I can pause.
What I am looking for is a way to pause any number of times.
I have written a program which uses a pid to check if the process is currently running and return a value based on the system call result.But the program core dumps
Code:
#include <stdio.h> #include <string.h int main( argc, argv ) int argc; char * argv[]; { int p_pid = 99; char buff[1000]; }
[code]....
What is the mistake in this code and is it portable in both unix/linux , is the method secure (grepping for program name )?
error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.
One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
I mean on the executable file. It just displays the results and quickly flashes away, cin.get() has no effect and system("PAUSE") is undeclared.
I never found a single sure way to pause effectively. Is there a method that works all the time? Sometimes cin.get() gets skipped even in the code itself. The IDE I am using is Code Blocks if that matters any.
I want to monitor a text file. So far what I have is the program reads and prints the names in the file to standard out. When the program reaches the end of the file, it closes.
I want the program to stay active and continue to print names as they are saved to the text file.
I was toying with FindFirstChangeNotification function, but it seems that returns a handle so I'm back to the drawing board.
So i have to use these prototype functions to run loops and to pause the program, the only problem is after i select a loop option and enter a number of dots to print in the loop it goes into an infinite loop and why, also when i try using the 4 option to exit it still asks me how many dots i want to print.
I want to run Unhidden.exe in drive N: and send char to that program. I use function like this
Code: system("N:/Unhidden.exe");
It can open Unhidden.exe but it run in visual studio 2010Projects . I try to use command N: and Unhidden.exe in cmd it can run in drive N: . So I try to use function like this
system("N:"); system("Unhidden.exe");
but it not found Unhidden.exe . How to use 2 command in sytem() function ?
I am writing an application that needs to temporarily disable the Play/Pause button that appears on multimedia keyboards.
Normally, a key can be blocked quite easily by installing a low level keyboard hook (WH_KEYBOARD_LL) where the KeyboardProc intercepts the key (in this case VK_MEDIA_PLAY_PAUSE) and returns a "1" instead of calling CallNextHookEx. I have tried this with other keys (including the Windows key VK_LWIN) and this works perfectly. I also have no problems with this method under Windows 7 where all keys, including VK_MEDIA_PLAY_PAUSE get blocked.
Windows 8 is a different story. When my application has input focus, everything works as expected, meaning the VK_MEDIA_PLAY_PAUSE key gets blocked and no other application responds to it. However, when my application loses focus, my hook procedure gets called (this was verified by sending out a OutputDebugString) but other applications respond to key even though I return a "1". As soon as my app gets focus again, everything is block as it should.
After some investigation, I found that the multimedia keys not only generate keystrokes but also generate WM_APPCOMMAND messages so I added ShellProc (WH_SHELL) hook with the following hook procedure:
LRESULT __declspec(dllexport)__stdcall CALLBACK ShellProc(int nCode,WPARAM wParam,LPARAM lParam) { // Do we have to handle this message? if (nCode == HSHELL_APPCOMMAND) { OutputDebugStringX(">>>>> HSHELL_APPCOMMAND");
[code]....
This procedure is only getting called when my app has input focus. Whenever I have input focus and return "1" the Play/Pause command gets blocked. As soon as I lose focus the procedure does not get called/hooked.
As I have mentioned, the code works for other keys, just not the multimedia keys.
Alternatively, another way of blocking the multimedia keyboards Play/Pause button?
I have to write a function for the destruction of the planetary system "solid". With the destruction of the planetary system, the asteroids where the gap between this one and the object, is smaller that "gap" will also be destructed. (so, they have to be deleted) The asteroids for which the gap is greater are converted to free-floating planets so they have to be inserted into the tree of free-floating planets. The total cost of the transport of all the asteroids that are converted into free-floating planets in the tree of free-floating planets should be $O(n)$, where $n$ is the maximal between the elements of the tree of free-floating planets of the star system to which the object belongs and the elements of the tree of asteroids of the planetary system of which the object has identifier "solid". The field "gap" of the new tree should have the value $0$. The destructed planetary system should be deleted from the list of planetary systems of the star system to which it belonged. (The tree of free-floating planets is not a binary search tree)
I have programmed a program for billing system. I have used parameters and arrays. All the functions are working except a one function. (Regular package function).
#include <iostream> #include <fstream> #include <string> #include <ctime> using namespace std; void main(int &minutes, int &minutesd,int &minutesn) {
I wrote a program which detects a pattern in an array then returns a valve (x) for each time it does. now i tried to call function patt in main so that i can print x but it doesn't let me do it.
#include <stdio.h> int patt(const int SIZE, char str[], int i, int c); int main(void) { const int SIZE=21; char str[SIZE]={'1', '0', '1', '1', '0', '0', '1', '0', '1', '0', '1', '0', '0', '0', '1', '0', '1', '1', '0', '1'}; int i, c=0;
