C++ :: Microsoft Code For Keyboard Input Interpretation?
Nov 22, 2013
at the moment my program is extracting keyboard data through accessing the virtual key states. However, it is not performing as I intended because the data I receive from the console does not concur with the actions the user performed.
E.G. When I type, it comes out like this.
what I get with my program: WWhhhheeen III typeeee, iiit ccoommes oout lllikkke thhhhiiis
TLDR: so basically Id like to know how other programs know how to interpret keyboard input, so that when I type I dont get multiple inputs of the same key press
I am trying to get my keyboard input into a function, so that I can call a function like updatebuttons() and set global variables to 0 if the button is not down at the moment and 1 if it is. It seems simple, but I can't seem to get it to work right; I am not use to working outside of windows, so I am still a beginner with SDL.
I'm not finished with this code, but I am stuck on this one glitch. This is what I have so far, and it's not working.
Code: int main() { /*Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return*/ printf("Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return "); int summation = 0, x, y; scanf("%d", y); for (y == x; summation <= M_E && x <= 34; x++)
I am writing an software that should be able to detect all keyboard inputs by the user. i.e., both hardware and software/on-screen keyboard.
This software is going to be written in a platform independent way and supposed to run on Windows, Linux, Android & iOS.
The idea is to capture the keyboard inputs from a low level, there by making sure that it doesn't miss any inputs even if it's a on-screen keyboard like in a mobile device.
I am looking at possible open source libraries that can be used.
I'm trying to simulate a ctrl+ keypress into a running application.
Code: #include <stdio.h> int main (void) { system("/usr/local/bin/rundb"); }
My problem is that the rundb program needs the user to type ctrl-b then s to actually start executing. What is the best way to handle this automatically? Some sort of fork/pipe?
I am trying to Write a program that inputs three integers from the keyboard and prints the sum, average, product, smallest and largest of these numbers. How do i go about it. What i dont know is how to come up with smallest and largest number .
I'm trying to write a C++ program that will allow a user to input a number from the keyboard. Then using a loop, that will perform 10 times, multiply the entered number by the loop counter. Print out the loop counter, the entered number and the product of the loop counter and the entered number. A one-time heading should be displayed before information is printed.
This kinda of what I have so far:
#include <iosteam> using namespace std; int main () { Start Declare: numScores, sum, score, avg, SENTINEL = 200 numScores = 0
[Code] ....
All the programs I have tried to make are not working?
I'm trying to create a program for my wife to be able to browser through and edit folders and specifically word documents- really just a shiny organization tool without having to open up Word. I'll be integrating other functions into this program but Word is what I'm worried about.
At the moment I've been able to create a file browser with the ability to add and remove files within the main directory of the program. Basically just C:Users\%user%mainDirdata*
Within the data folder I have the main folders which will be displayed as tabs across the top and then any subfolders of the main folders will be displayed on the left side after you click on the main tab.
[URL]
I'd need the toolbars to be integrated into the program across the top and then a window that changes depending on the document selected on the left side based on the content of the word document located in that folder. I haven't been able to find anything online and I'm not really able to spend $800 on the alternates that look like they just do automation as well.
I checked through the net and most of the solution like clrcr(); is not working for microsoft visual 2010. SO i was wondering for those who was using the same ver of c++ as me how do you clear the screen?
I m trying to lock a single skeleton using Microsoft Kinect SDK v 1.7 . My requirements are
•First lock a single skeleton. •Check the tracking state of the of the locked skeleton. •If the tracking state of the locked skeleton is NOT Tracked,then • ----->check for the next closest skeleton •----->lock this skeleton.
How do I do this using vc++2010. The code which i tried is given below.
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1520 1730 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1730 1730 [1730==1730] Enter two times in military format (e.g., 1730 1520): 1760 1520 1760: [INVALID TIME 1] Enter two times in military format (e.g., 1730 1520): twelve 2 [INVALID NUMERIC INPUT]
This program gets input from a file and output to the screen and to a file. The difficulty I am having is summing the number I retrieve from the file for the individual numbers of sightings.
#include <fstream> // enables us to read and write files #include <iostream> // for cin and cout #include <cstdlib> #include <string> // enables us to hold strings of characters #include <cctype> using namespace std;
I am in the process of writing a program that will give the appropriate color code for a resistor after the user enters an integer value for the resistance needed and selects the tolerance form a list. My question is this: Is there a way to allow the user to enter a value such as 75000 and C++ use each digit separately, as if they entered 7 [enter], 5[enter], 0 [eneter]... and so on? But, then use the entire value as an integer too? Also, it should read a value such as: 45835, as 45000, or 1843 as 1800.
Code: struct _Node { // list node _Genptr _Next; // successor node, or first element if head _Genptr _Prev; // predecessor node, or last element if head _Ty _Myval; // the stored value, unused if head };
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?
I need to run some operation if a key from keyboard is pressed. so I go with
Code: c=getchar();
to get it read. yet the user could press a key anytime; so I'd need some if-loop. no plans on how it'd look like though...I suppose something like this below wouldn't work right?
how can I allow pressing some keys on the keyboard in C++? I mean, when you are in the console and you are only allowed to press numbers before pressing enter, for example.
