C++ :: Character Recognition With Artificial Neural Network
Feb 3, 2015
create a artificial neural network for character recognition. URL.....Background:
- I have a good understanding of C++ and Assembly code and currently working on my java skills.(PF1, PF2, Paradigms, and microprocessing classes)
-I've programmed microprocessors(PIC) and will be using a PIC32MZ processor to operate the camera data collection and ANN operation. Currently, I plan to program this PIC in Assembly and C since I do not know if C++ will work on the microprocessor hardware.

I've been coding for about 10 years now and it just got to my mind that I would like to learn about how I can create speech recognition software. I am mostly interested in doing this from ground 0 not because there are no other libs I can use, but it's more of an interest to me.
grasp this new and magnificent feature that's becoming more and more used nowadays.
My preference would be coding in C++ (more because of OOP that's why not C) and I don't really like Java.
I know what I'm getting involved in but I am thrilled and willing to go all the way to achieve my goal.

i have a .txt file with a bunch of numbers(1...99), millions of them, and i would like to make a program that recognizes patterns(if exists, i don't know) of numbers in this file. What will be the starting point? How could i do that? I read i could do that with Neural Network. Is there other way?

All day long I tried figuring out how to setup VOCE [URL] ....
I am using VS 2010.
What I did:
* Downloaded JDK
* Downloaded the VOCE, extracted and put in c:
* Opened VS and in properties->Vc++ Direcotories:
* In Include Directories i added: C:voce-0.9.1srcc++, C:Program * FilesJavajdk1.7.0_45include, C:Program FilesJavajdk1.7.0_45includewin32
* In Library Directories i added: C:voce-0.9.1lib, C:Program * FilesJavajdk1.7.0_45lib
ALSO: I didn't get what i suppose to do with C:voce-0.9.1lib everything there * is winrars
Tried to compile a sample file and it gives me the error:
Testing.obj : error LNK2001: unresolved external symbol _imp_JNI_CreateJavaVM@12

This problem relates to a program i am developing to ping all hosts on a network.
So far I've managed to access a PostgreSQL database to retrieve a CIDR network address e.g. 192.168.52.14/24.
I have then managed to mask the bits to get the network address.
So for e.g. above its 192.168.52.0
I now need some kind of algorithm to loop through available hosts so from.
192.168.52.0 - 192.168.52.255
I have got as far as deriving the network and separating it into an int array
So I have : ip_start[]= {192,168,52,0}

I'm wondering if there is a library for C++ that supports threading over the network, maybe with a threading pool and a specific protocol; or if there is just a de-facto protocol for doing threading over the network.

I want to change my system IP, subnet mask, host name etc. using win32 VC++.
I've tried AddIPAddress function but that's not persistent.
I want to change it that it should be change without rebooting system and should be there after restarting the system.

The following code prevents windows from letting the monitor go into sleep mode when the program is active and wakes the monitor up after a scanner scans something.
Code:
protected override void WndProc(ref Message m) {
if (m.Msg == W32.Const.WM_SYSCOMMAND &&
(m.WParam.ToInt32() & 0xfff0) == W32.Const.SC_MONITORPOWER && m.LParam.ToInt32() != -1)
{
return;
[Code] ....
When the program is started normally it works fine. But when the program is started from a network share it goes to sleep anyway and the OnScan does not work anymore. Removing the Send Message line makes On Scan work again but then the monitor wont wake up on a scan of course.
What could be the problem here when started from the network?

I have an application in c# that i don't want it to connect to the internet in a virtual environment, like virtualbox, vmware virtual pc and so on. Therefore i though that disabling the virtual network card inside the virtual machine would be a good idea.

I know I can use ping internally to test a device's connectivity. What can I use to test devices on another network (assuming ports are forwarded, and their IP addresses are at my disposal)? I was looking into the TCP Client class.. would that also work with devices using DynDNS?

I want to build a proxy, middleman between various client programs on my machine and servers outside, like this:
Client -> Proxy -> Server, Client <- Proxy <- Server.
OSes are Windows XP, 7 and 8.
Within that proxy I want to analyze data before it reaches it's destination and have full control over it to the point where I can prevent a packet from reaching it's destination if my program finds something suspisious going on. I need incoming and outgoing traffic of specific adresses and ports to be forwarded into my application on my client machine. My app then should deliver packets to their destination after they were analyzed.
The parts where data is received, analyzed, manipulated if needed, and sent is something I could code with no difficulty. But the concept of redirecting and forwarding is hard for me to grasp at the moment. I'd like to know at least what winsock functions I have to use.
If it's possible, I would like to use Windows libraries only, nothing from 3rd parties.

Currently I'm trying to do something extremely basic: delete or move a file
I have a mapped network drive (Y) where I have a file I need to move from one folder to another
First was doing the obvious:
System.IO.File.Move("Y:TempFile.txt", "Y:Temp2File.txt");
Not much to go wrong here, right? As long as I have the correct permission to write in the folders and the folders exists, this would normally go smooth. But for some reason it only copies the file. The source file still exists, but it has successfully copied the file to the destination folder. No exceptions has been thrown or anything... but the file still exists in the source directory
I then changed the code to the following:
System.IO.File.Copy("Y:TempFile.txt", "Y:Temp2File.txt");
System.IO.File.Delete("Y:TempFile.txt");
Console.WriteLine("See mommy, no Exceptions");
As expected the file copies correctly, but the delete command is completely ignored. The file is not deleted, but the Console.WriteLine command is called
I'm running the application as the logged in user. The user has permission to delete the file. If I try from Windows Explorer, the file is correctly deleted. Unfortunately my application refuses to delete the file and even worse, it will not even throw an Exception.

I basically want to develop an application which print an existing file on reception of a network event (application will be running on a seven 64 bits PC).
I wonder which application type would be the most suitable (and the simplest) for that (console win32, win32 app, MFC app ...). As this application does not need user intervention (print on network event), I'm not sure that I need a MFC application or a win32 app.

I keep getting this warning message and I do not know how to fix it. Is it because I'm using char to instead of strings to replace all 't' with 'lp'?
#include<iostream>
#include<string>
#include <stdio.h>
using namespace std;
char * scanf(char * a) {

I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.

In my program, I'm supposed to read a text file (the name of which is given to me as a command line paramater, as long with an integer), and display the text in a specific format (each line can only be as long as the integer). However, I'm having trouble even reading the text file. I don't know the syntax. I'm only allowed to edit the function that does the formatting, and the code in that is
void typeset (int maxWidth, istream& documentIn)
I don't know how to 'read' the file, as most examples online are ifstream, or openFile or something like that. What I want to do is just read the first character of the file, and continuously keep reading characters until the end of the file.

So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.

I am trying to make kind of a messenger using Socket/Network Programming
My program should allow clients to register or sign in, after they are signed in they should see a list of the other signed in people whoever I select from that list I should be able to implement using multiple threads as well.
I have done this much:
User.txt file
ahsan,1234
bilal,1234
pappu,1234
babu,1234
Client.c
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>
[code]....
Now issue is in this code I am getting error SEGEMENTATION ERROR, CORE DUMP

I am currently reading several values one after another from a file like so:
Code: ifstream f;
double x;
double a, b, c, d;
f.read((char *)&x, sizeof (double));
a = x;
f.read((char *)&x, sizeof (double));
b = x;
//etc ... for several other values Question:
How can I read every (lets say) 3rd value instead of every next value from the file

I'm trying to get the int value of each character in a string and then add them all together so I can do a 1's complement of the total value. I'm trying to do simple checkum kinda of thing for verification of data.
For example: string DPacket = "Hello World!";
I would like to have each character added and do the ones complement. Will it be easier to convert first to int and then add or any other easier way? So my result should be the decimal value addition of each character and then do the ones complement to that.

How can I move a character around a 2D map? After some research and a bunch of work I made a function for movement:
unsigned int gamespeed = 100;
unsigned int stage = 1;
void controls()
{
[Code]....
Maps are stored in a different .cpp file
So this code works, but is complicated, ugly and evil (I have to make a pointer to the first map and change the pointer to the next map every time the user reaches the exit, without the pointer this code is, of course, incompatible). How can I reduce this code to be less evil/ugly or at least smaller?
Also it would be nice if the user could move around with arrows as well as with WASD
