Visual C++ :: Capturing Both Soft / Hard Keyboard Inputs?
Oct 4, 2013I have a C++ WIN32 DLL that acts as a server for a UI. Now i want to capture all keyboard inputs in the PC on the WIN32 dll, whenever the UI has active focus. If the user is typing something into another app, i don't care.
The trick is that, the keyboard can be both a software keyboard or a hardware keyboard. I want to be able to capture every keyboard input from the user on the PC in which the UI and DLL is running.
Is this possible to do? How can i implement this?
C++ :: Capturing Files In A Directory
Jan 9, 2013I'm using the following code to capture all files in a directory - but when I pass the "path" var such as "C:SomeDir" ffd.cFileName is just simply "SomeDir" and is seen as a valid folder and no more files are processed.. I'm trying to get the contents in that folder. I'm following this example here - [URL] .....

C :: Parsing String And Capturing In Variables
Nov 3, 2013I have an input file that contains any number of lines. Each line will follow the same structure. There will be 5 fields, separated by 4 commas. Fields 1 and 3 will be single characters, fields 2,4,5 will be integers. Example:
<A, 123, B, 456, 789>
I need to iterate over each line, parse out the fields, and capture each field value into a separate variables.
header file: Code: #include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>

I've used similar code to this before, but this time I'm getting the dreaded pointer from integer error on my strtok lines:

C :: Run Some Operation If A Key From Keyboard Is Pressed
Jun 2, 2013I need to run some operation if a key from keyboard is pressed. so I go with

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.

Apr 13, 2014I 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)) {

C++ :: Enter By Keyboard Instead Of Command Line Arguments?
Mar 9, 2013Actually the below program is for Dispersal Algorithm called Rabin-IDA; this algorithm divided the data into N pieces and then recombine it from M pieces (such that M<N).

Now my question is, How can i make this program enter the file name by keyboard??(i mean enter the files name by user from screen not as command line arguments)

Apr 25, 2014I use the following code segment to read and output the text piped to a program. If there is no piped text, the code segment is skipped and then the program continues. What I need to do is restore stdin to the keyboard after reading from the pipe. I use the PeekNamedPipe() and ReadFile() because reading from stdin blocks until it has something, and I don't want that to happen. After reading from the pipe, the program begins to execute, and the main loop can be paused and it prompts for a command. I just can't figure out how to restore input to the keyboard. Obviously the platform is Windows.

C++ :: Microsoft Code For Keyboard Input Interpretation?
Nov 22, 2013at 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.

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

C# :: Unable To Change The Individual Keyboard Layouts
Jan 14, 2014i am developing a multi-lingual application allowing users to change language as well as keyboard layouts (through combobox).

I don't just want to change the input language, i was also want to be able to type in different keyboards. Here's the code (e.g. for English language), the imports etc are added already..

Visual C++ :: Low-Level Keyboard Input Detection?
Mar 13, 2014I 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.
