I could easily give you the numbers, but it would be of more benefit to you to create a little test program that uses getch() to get those keys (and others) and print their values to the screen. You can then use those values in your program.

How to define arrow keys in c.
1. Define keys.
2. Put kbhit() in a function.
3. Create a loop.
4. Thats it.
Step 1.
#define UP 72
#define DOWN 80
#define LEFT 75
#define RIGHT 77
Step 2.
void pumpKeyboardMessages(void)
{
if (kbhit())
{
ch=getch();
}
}
Step 3.
while (ch!=ESCAPE)
{
pumpKeyboardMessages( );
}
Step 4.
Here's an example of usage:
#include <conio.h>
#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>
#define UP 72
#define DOWN 80
#define LEFT 75
#define RIGHT 77
#define SPACE 32
#define ENTER 13
#define ESCAPE 27
#define TAB 9
#define INSERT 82
#define F1 59
void pumpKeyboardMessages(void)
{
if (kbhit())
{
ch=getch();
switch (ch)
{
case LEFT:
break;
case RIGHT:
break;
case UP:
break;
case DOWN:
break;
case ENTER:
break;
case SPACE:
break;
case F1:
break;
case TAB:
break;
}
}
}
int main(void)
{
getReady();
initGame();
bas=time(0)+1;
while (ch!=ESCAPE)
{
pumpKeyboardMessages( );
}
return 0;
}

Hi all friends;
I am a beginner in c(win32 console). I want to change the colour of characters & background in c. How to do it?

1. Read the guidelines[^] before posting a question.
2. Do not use capitals to emphasise, it is considered bad manners.
3. Do not make demands for full explanations/code. People will give what they can without being prompted.
4. Learn to use Google, Bing and MSDN to do your own research first.
This link[^] has some suggestions to get what you want.

Hello all;
I'm a beginner in c. I should program a game(it's maze).
So I am dealing with this problem that can't get the walls from input.
because user should be able to put the walls by using an array.
Apologise me because bad English writing.

First, I am writing everything in C using Visual C++ 6.0
Second, I have created a dialog box that contains an edit box located inside a dialog box and I cannot seem to find a way to change the font size of the edit (text) box. It's basically a user id window, but it's defaulting to a small font.
I can set the text inside of the box just fine:
SetWindowText ( GetDlgItem ( window, IDC_ID_WINDOW ), (char)current_id_string_g ) ;
but the font is small =(
any ideas of how to change the font size of a particular edit box?
Thanks

Send it a WM_SETFONT message, perhaps?

Huzzah! You led me down the right path. Here's the code to changes an edit box font (at least, this works fine for me).
HFONT hFont ;
HWND x = GetDlgItem(window, IDC_ID_WINDOW) ;
HDC hdc = GetDC ( x ) ;
hFont = CreateFont(48,0,0,0,FW_NORMAL,FALSE,FALSE,FALSE,DEFAULT_CHARSET,OUT_OUTLINE_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY, VARIABLE_PITCH,TEXT("Impact"));
SelectObject(hdc, hFont);
SendMessage( x, WM_SETFONT, (WPARAM) hFont, MAKELPARAM(0, 0) );
(void) UpdateWindow(window) ;

Hi
I'm trying to write my own debugger I have
most the kinks squared away with the exception
of a few namely I am trying to re-create the
yellow arrow which follows you along when you step
through code
1) I was not quite sure if it's a function of a cursor
or a owner draw control
I had code to manipulate the cursor ::onsetcursor
which I had gotten to position the cursor
however when I added code for a custom
cursor LoadCursor(..... ".cur")
I followed all the steps putting in my resource file
then Setcursor after Load got all good return codes
but my new yellow cursor failed to appear
I am looking for some insight if I am on the correct path
Rhankx

if i had to guess, i'd say it's just a bitmap they draw on the editor window at the appropriate spot - neither cursor nor custom control.
|
|

|

Yeah you are probably right doesn't fit into any of the predefined windows class
I guess if you have a white rectangular background for the arrow you van use bitblt to move it along

This is a tough one. I have a process running in a console that sometimes "freezes" when trying to read data from serial port (or USB).
The issue only happens if the console does not have focus. If i click on the console so it has focus, the serial data starts coming in again. If the console has focus all the time, the issue never occurs.
It doesn't look like console focus can be detected with SetConsoleCtrlHandler or SetConsoleMode so the question is...
How can a console having focus effect serial port I/O? It doesn't look like a timing issue with console output messages.

Hi,
No idea if any of this lot is any good, but here are some things I'd try in the same situation:
- Does the slowdown happen with a /subsystem:windows application as well as a console one? If it does then it might be due to threads changing priority when an application is minimised.
- Is your serial I/O code in it's own thread? Normally I wouldn't advocate spinning off threads wily nilly but if the I/O is in it's own thread you don't have to worry about the UI thread being blocked in a message loop somewhere and not able to read from the serial port.
- Does the same thing happen if you run the app as an administrator or ordinary user? If it does there might be a security problem.
- Is there anything else that might be interfering with the serial I/O? Is the COMM port used for anything else or have you several devices on the same USB hub?
Anyway, hope that's not a complete waste of time and there's something in there that might help you resolve your problem,
Cheers,
Ash

Thanks for the tips. The process is run as Administrator and I just confirmed all reads and writes are from same thread. Not sure about the interals of the USB hub... its an embedded system and serial ports and USB are not standard.
Any more ideas? This is a tough one and has me baffled. Maybe its something in the Windows kernel having to do with handling IO since I don't see a public API to listen to focus events for a console.

After a little more digging, there was another thread trying to do some occasional writes. The original code had a "read" lock and a "write" lock so it was designed to allow reads and writes at same time but doesn't seem to work reliably unless all I/O is synchronized (one lock for both reads and writes).
