Thread: How to Get Keyboard event????

Dear Sir,

I am doing project..one part of project i wanted to catch the keyboard events like if i press A ,B...means i should get equivalant value
Ex: if i assign A="string" means if i press A means it should display string
overally How to catch the keyboard events?
give me logic i will try to implement..if you found any useful links for more information please provide me..
Thanks in advance to all

Does it involve special characters such as backspace/return? Do you need low-level access? Do you plan to program for Windows using dialogs?

If it is a concole application it might be easier to take the usual route: let the user type 'A' and Enter and use standard input methods.

There is no natural connection between keyboard keys and variable names in the program. It does not matter at all if you call your string variable A or something else. It is up to you, as a programmer, to ensure that the correct string is displayed.

For getting the character without having to wait for enter:

if you don't want to study it, then:

Code:

#include <windows.h>
#include <iostream>

using namespace std ;




char GetInput()
{
HANDLE input=GetStdHandle(STD_INPUT_HANDLE) ;
LPDWORD length ;
INPUT_RECORD record ;
char ToReturn ;
     while (record.Event.KeyEvent.bKeyDown)
    {
   ReadConsoleInput(input,&record,1,length) ;
   ToReturn= record.Event.KeyEvent.uChar.AsciiChar ;

   }
return ToReturn ;
}

//now whenever testing the function:

int main()
{

string Letter_A="Amazing addition to my function collection really works" ;
if (GetInput()=='a')
cout<<Letter_A ;
else cout<<"You either didn't enter \"a, or Garland tried to fool me! " ;
cin.get();
return 0 ;



}

I have tested it for myself, so I think it should work.

Code makes my eyes weep. So poorly indented I don't want to look at it.

Code:

#include <windows.h>
#include <iostream>

using namespace std ;

char GetInput()
{
	HANDLE input=GetStdHandle(STD_INPUT_HANDLE) ;
	LPDWORD length ;
	INPUT_RECORD record ;
	char ToReturn ;
	while (record.Event.KeyEvent.bKeyDown)
	{
		ReadConsoleInput(input,&record,1,length) ;
		ToReturn= record.Event.KeyEvent.uChar.AsciiChar ;
	}
	return ToReturn ;
}

//now whenever testing the function:
int main()
{
	string Letter_A="Amazing addition to my function collection really works" ;
	if (GetInput()=='a')
		cout<<Letter_A ;
	else
		cout<<"You either didn't enter \"a, or Garland tried to fool me! " ;
	cin.get();
	return 0 ;
}

Indented and looks SO much better.
Even if you're posting a sample, please INDENT the code, because otherwise it's almost unreadable - like your previous example was.

It's not too much to ask of you to actually indent your code, is it? That's all I ask.
(Not criticizing your post nor your code - just your indentation.)
