Hi everybody,
It's me again...Pelo, for an other beginner question...
What the code should be in C++ to wait for a keyboard entry in order to
execute the sequal of my program...
11  18248 
I found by myself...
#include <conio.h>
cout << "Press any key to terminate this program. " ; getch();
The getch() function call causes the program to wait for a single keystroke.

But alas it's not part of the C++ language. It's an
'extension' provided by your implementation, not topical
here. Here we discuss the ISO standard C++ langauge, which
has no means to do what you're asking.

c++ doesn't have such a concept.
If you work under character environments such as unix or old dos you'll
usually call a single function to achieve that. Non standard headers like
<conio.h> for dos may provide what you're looking for. Others will point you
to correct newsgroups.
If you work under some GUI like Windows or the X, than your whole program
concept changes. You wait for specific messages/callbacks from your
OS/GUI/Framework manager or whatever. And that's a complex topic which is
not discussed here.

How would you do
[nonblocking input]
in ISO standard C++...

Like I said, it cannot be done with standard C++.
You'll need to use an extension, such as the
one you mentioned. However you should note
that this will only work with that particular
compiler, others will have their own way, if
they have any at all. When you encounter this
situation, I advise you to isolate and clearly
identify such uses, so porting will be easier
when the time comes.

> What the code should be in C++ to wait for a keyboard entry in order to execute the sequal of my program...
You can use std::cin which redirects input from stdin (your keyboard) to a
string in your program. Example
#include <string>
int main()
{
std::string sInputString;
// Wait for input from stdin (the keyboard)
std::cin >> sInputString;
// Print out to the screen what the user just input
std::cout << "The user just input the following string: " <<
sInputString << std::endl;
}
I hope this helps
What is wrong with
std::cin >> SomeString;

How would waiting for keyboard input be _non_blocking? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi All,
I'm in the process of implementing a virtual keypad: I have a wxFrame

editor frame and displayed inside the editor. This is working fine.
However, if I want a proper virtual keyboard I should also be able to

When you enter an option group you can move to each option with the
arrow keys and select with the space bar.
Option groups don't have keydown events so has
anyone come up with a way to allow keyboard entry for
option groups?
Just a simple way to select with 1-5 from the keypad or some such.
thanks for any help or a link to what to read.

The Python standard library unfortunately doesn't provide a module that
gives unique names to common keyboard events.
Even Tkinter had to write a complex parser to find out which keyboard
