Why don't you explain why you need to do this? It is likely there are much better ways of doing whatever it is, unless you are trying to provide a very low level service.

Then instead of setting the input variable to "18-2-21" (obviously not what csurfer intended), use fgets to get a line of user input. Also you could use sscanf() as long as you make sure to check its return value!

Really, Notepad++ didn't display the hyphen? That's very strange.

You can use a tm structure for the date of birth, convert it with mktime(), and subtract that from time(). Then convert your answer back into a tm struct.

You're not going to learn anything by having me give you code. Find a good tutorial. Besides, i'm sure there's examples of this game all over the web anyway.

Sorry, wrong forum! I'm sorta out of it.

Where exactly are you calling session_start()? And that error just means you have some sort of output (check for spaces, newlines before your <?php tags) before you have called session_start(). If you have to do this, consider output buffering.

A bubble sort but with the comparison flipped.

Compress the sound beforehand, then apply the gain. Try here for some info on dynamic range compression.

Your post describes each step perfectly. Computer generates a number, user makes a guess, computer tells what range the number it is in, and so on. If you're problem is writing the code, learn some c++ first.

Definitely consider using a compression technique. Otherwise, scaling up can cause distortion. Its gross.

You could probably pull it off with some clever javascript. That solution would be more inline and portable than a mandatory plugin anyway.

Create a counter of how many "levels" of braces you are in. What do you mean by reposition? To see if they are part of a block, look at the statement before the opening brace. If it is a for loop, if statement, etc. then it is valid.

That looks like a good implementation to me, and without the comments its really quite short and sweet.

Have an array for each possible number, have each element be a flag as to whether the number at that index has been generated.

If you can't find it, make it yourself. It's not too difficult. Use an existing image library (DevIL works well, covers almost any format). Then get the image data and apply a rotation. Google/Wikipedia will have the math you need for rotation.

I don't know whether DevIL would work with your compiler, you're welcome to try it, but TurboC++ is terribly outdated.

A simple solution (but will give more flexibility): define two arrays, one with source characters and the other with destination characters to replace those with. Arrays are matched by indices. Just make sure there are no repeats or decryption may not work correctly.

1. Get a more recent compiler
2. DevIL works well (you may need to learn some WinAPI stuff depending on how much control you really want)

Sounds like edge detection would help.

They should be put in .c files? I never learned great project design.

As I said, take a look at the sample architecture for download. It will give you something to model your own code after.

in the source file..u can just go..

#include<string>
#include...
#include"someheader.h"
#include"anotherheader.h"

and remove #include<string> in the "someheader.h"

If you had read any of the previous posts, you would have seen this point:

So, my question is: why would you want to require people to follow extra instructions just to use your header file?

Wow, I was just refencing things by all the wrong names. I knew it was something stupid like that! Thanks for the catch, me_ansh.

Use code tags, tell which line is producing that error.

Visual C (2008) is acting as if I never included a header file (wave.h) that I am using, but the #include statement is definitely there. Here's my main (BPM analyze.c):

#include "stdafx.h"

#include "common.h"
#include "sound.h"
#include "wave.h"

int main(int argc, char* argv[])
{
	SAMPLE samples[2];
	unsigned int i, j;
	WAV_FILE file;
	FRAME *frames;

	getWaveFile(&file, "Lobby.wav");
	extractFrames(frames, &file, 0, 1);

	//printf("32 bit: ");
	for(i = 0; i <= 1; i++)
	{
		for(j = 0; j < file->info->numChannels; j++)
		{
			printf("%d ", frames[i][j]);
		}
	}

	getchar();
	return 0;
}

Common.h (probably not the issue):

#ifndef COMMON_H
#define COMMON_H

#define MAX(a, b) ((a > b) ? a : b)

typedef enum{false, true} bool;

#endif

Sound.h:

#ifndef SOUND_H
#define SOUND_H

typedef unsigned int SAMPLE_32BIT;
typedef unsigned int SAMPLE_24BIT;
typedef unsigned short SAMPLE_16BIT;
typedef unsigned char SAMPLE_8BIT;
typedef union
{
	SAMPLE_32BIT _32bit;
	SAMPLE_24BIT _24bit;
	SAMPLE_16BIT _16bit;
	SAMPLE_8BIT _8bit;
} SAMPLE;
typedef SAMPLE **FRAME;

#endif

Wave.h:

#ifndef WAVE_H
#define WAVE_H

typedef struct
{
	unsigned short formatTag;
	unsigned short numChannels;
	unsigned int samplesPerSec;
	unsigned int bytesPerSec;
	unsigned short blockAlign;
} WAVE_INFO;
typedef struct
{
	WAVE_INFO *info;
	SAMPLE *data;
} WAVE_FILE;

bool getWaveData(WAVE_FILE *file, char *filename)
{
	// function body, not important
}

void extractWaveFrames(FRAME *frames, WAVE_FILE *file, unsigned int startFrame, unsigned int endFrame)
{
	// function body, not important
}

#endif

And here's Visual C's complaints:

bpm analyze.c(11) : error C2065: 'WAV_FILE' : undeclared identifier
bpm analyze.c(11) : error C2146: syntax error : missing ';' before identifier 'file'
bpm analyze.c(11) : …

I was just wondering what your "wrong" comment was in response to. If you were saying that standard c++ headers in fact do not use #ifndef statements, that would be important. I see that is not the case.

For the sake of information, are you saying I am wrong about headers, or just spouting your opinion on C++?

Use fgets to read one line, strtok to split each line between spaces, sscanf to break apart each value. Do this all in a loop to read multiple lines.

Good point. With both under your belt, not only will it strengthen your overall programming knowledge, the flexibility it would give you would be more impressive on a resume.

The first article you posted has a very concise description of this layout. It describes the class architecture you will use (study object oriented programming in PHP), including the use of abstract, super, and sub classes. It also defines the most common and most helpful methods to define for each class. For the purpose of actual coding, these are the basic things you need to know:

Model: SQL functions. Learn SQL itself and the PHP functions for working with your database of choice (ie. MySQL, Oracle, whatever).

View: Templates, optionally

Controller: OOP concepts should cover it as this just connects the other two classes in a logical manner.

And definitely look at the sample architecture for download at the bottom of that page.

And your origional question seemed to be about whether or not you could include <string> multiples: well all the standard headers use #ifndef too! Cool, right?

That would be the correct way to call it. The function would still not work as planned, as you set hours to zero inside calctotal. The function itself should be something like:

float calctotal(float hours)
{
	
	// got rid of: int hours=0;
	
	

	if (hours < 3 && hours > 0)
		total = 2;
	else
		if (hours >= 19 && hours <= 24)
			total = 10;
		else
			if (hours>3 && hours < 19)
				total = (hours-3) * .5 + 2;
			else
				if (hours > 24){
				printf("invalid input......try again!\n");
				scanf("%d",&hours);
				
	}
				return total;
				
}

Use fgets to read one line, strtok to split it on spaces, '=', etc.

If you don't know how to open the file, read about fopen, fclose, etc. If you don't know how to read the information, read about fgets, fread, sscanf, etc.

Even if you could use scanf for your purposes, it is better to use fgets anyway.

What is the problem with using || ? It is a completely valid part of the C language. There might be some obscure way of doing the same comparison without it, but it would be useless to even try it.

Open your php.ini file, look for the values of SMTP and smtp_port. Change these to the appropriate server and port. If you can't access php.ini (hosted site) use ini_set() like the error suggested.

I haven't worked with Open-Realty so I really can't tell you. All I suggest is learn PHP and SQL thoroughly and study the code you already have thoroughly. This is not exactly a simple fix. Or, you might want to google to see if anyone else has done this and provided code.

Why yes you can! (I suggest learning HTML more thoroughly)

die("File name is too long please rename your file shorter and then upload again: go <a href=\"previous.html\">back</a>\n");

Replace previous.html with the page you want to send the user to.

You're right, that's different from:

char sudoku[] = { '0', '0', '1', '0', '0', '0', '0', '0', '9',
                  '6', '0', '8', '7', '9', '4', '0', '2', '0',
                  '0', '0', '9', '1', '0', '5', '0', '0', '0',
                  '0', '0', '0', '6', '7', '0', '0', '0', '2',
                  '0', '8', '0', '0', '0', '0', '0', '6', '0',
                  '0', '9', '0', '4', '3', '0', '0', '5', '0',
                  '0', '0', '4', '0', '0', '0', '0', '1', '0',
                  '9', '3', '0', '0', '1', '0', '8', '4', '0',
                  '0', '0', '2', '0', '4', '3', '0', '0', '0' };

C will convert actual numbers into the ascii character at that index.
To get the char from a number:

char seven = 7 + '0';

Obviously that code is unecessary, but when working with variables it becomes useful.

struct termios chk_options;
tcgetattr(fd, &chk_options);
if(chk_options.c_cflag & CS8) printf("Eight bit mode\n");

A list of the other flags are here (11.2.4 Control Modes)

I found your site, Ezzaral, very helpful. Thank you.

What do you mean you can't make it work? Output/error messages are most helpful. And your statement would look like:

$save_name = date("d m y_s i H") . ".txt";

Check date for help formatting, pathinfo to properly get the file extension.

Sorry, I haven't tested these. The third one should be:

// Get file name from URL and remove any bad filename chars.
		$url_parts = explode('/', $url);
		$num = count($url_parts)-1;
		$file_name = $url_parts[$num];
		$badchararray = array(" ", "'", "\"", "$", "&", "%", "-", "#", "^", "*", "(", ")", "~", "@", "/", "?", "=");
		$file_name = str_replace($badchararray, "", $file_name);
		$file_name = stripslashes(strtolower($file_name));
		if(strlen($file_name) > 40)
			print("File name is too long please rename your file shorter and then upload again.\n");
		else {
			if ($append_file_name == true) {
				$save_name = $id . '_' . $file_name;
			}else {
				$save_name = $file_name;
			}
			// uploading code
		}
		// any finishing/cleaning up code you need to do

Just curious, what exactly happens with the second one?

It would seem what I need is an envelope follower. Google hasn't been much help, anyone know of any good links/tutorials?

Using system() commands is not a good idea, and windows specific functions are not a great solution either. You can use Clock() instead of sleep. Also, check out these special control characters as a way of clearing the screen.

// Get file name from URL and remove any bad filename chars.
		$url_parts = explode('/', $url);
		$num = count($url_parts)-1;
		$file_name = $url_parts[$num];
		$badchararray = array(" ", "'", "\"", "$", "&", "%", "-", "#", "^", "*", "(", ")", "~", "@", "/", "?", "=");
		$file_name = str_replace($badchararray, "", $file_name);
		$file_name = stripslashes(strtolower($file_name));
		if(strlen($file_name) > 40)
			die("File name is too long please rename your file shorter and then upload again.\n");
		else if ($append_file_name == true) {
			$save_name = $id . '_' . $file_name;
		}else {
			$save_name = $file_name;
		}

That would stop the rest of your code from executing, but it is a messy way to quit. Alternatively:

// Get file name from URL and remove any bad filename chars.
		$url_parts = explode('/', $url);
		$num = count($url_parts)-1;
		$file_name = $url_parts[$num];
		$badchararray = array(" ", "'", "\"", "$", "&", "%", "-", "#", "^", "*", "(", ")", "~", "@", "/", "?", "=");
		$file_name = str_replace($badchararray, "", $file_name);
		$file_name = stripslashes(strtolower($file_name));
		if(strlen($file_name) > 40)
			print("File name is too long please rename your file shorter and then upload again.\n");
		else {
			else if ($append_file_name == true) {
				$save_name = $id . '_' . $file_name;
			}else {
				$save_name = $file_name;
			}
			// uploading code
		}
		// any finishing/cleaning up code you need to do

How about GetAsyncKeyState? (windows specific function)

Can anyone else not stand the attitude of some people that the world owes them something and they should complain and make a scene until they get it?
