hello friends
plz help me in this problem. i m making an intrusion detection system using vc++, in this output of sniffer has to be written in text file. is there is any function for that.
thanx

(all platforms) C/C++ functions: fopen, fclose, fwrite, fread, fprintf, fputs, fputc.
(Windows specific) C/C++ functions: CreateFile, CloseHandle, WriteFile, ReadFile.

thanx for ur reply
but can u send a small module in which it takes an output of exe file and write it in text file
bye

The functions I listed assumed that the exe file was one that you wrote your self. If not you could probably write a program that uses shell programming to capture the output and copy it to a text file, but that would be the (VERY) hard way. If the exe writes the output to stdio/screen/console (standard I/0), then I would look into using redirection. That is you could add redirection command to the short cut.
I have not used redirection for several years, but this is basicaly how it worked in DOS:
SomeProgram.exe > output.txt
What that does is sends the output to the text file, instead of the screen.
Anyway, maybe you should do a search for redirection on the command line.

Are you using MS-DOS based? or MFC EditBoxes?
MFC EditBox...
<br />
#include "fstream.h"<br />
<br />
CString strE1Input;
CString strFilename;
GetDlgItemText(IDC_EDIT1,strE1Input);
strFilename = "Info.txt";
ofstream a_file ( strFilename );
a_file<< strE1Input;
a_file.close();
**Hope that helps... If ur using MS-DOS (Windows App) let me know**

MS-DOS based...
<br />
#include "fstream.h"<br />
#include "iostream.h"<br />
<br />
using namespace std;<br />
<br />
int main()<br />
{<br />
char first[50];<br />
char answer[2];<br />
<br />
cout << "Enter First Name:";
cin>>first;
cout << "Your Name is:" << first << "." << endl;
cout << "Is this Correct? (y/n)" << endl;<br />
cin>>answer;<br />
<br />
if (answer == "y") {<br />
ofstream a_file ( "Names.txt" );
a_file<< first;
a_file.close();
cout << "Saved in Names.txt" <<endl;<br />
}<br />
if (answer == "n") {<br />
}<br />
else {<br />
}<br />
}<br />
Forgive me if this doesnt compile... Just a quick type out...

Why didn't you list the way to do it in C++ ? ifstream/ofstream rocks, fopen/fclose totally sucks.

1) I admire your work!
2) In my opinion, ifstream/ofstream sucks!
3) We are way off the subject of the post (personaly I do not care).
Since he appears to redirect the output to a file.
As for item (2), it is too complicated. If some one does not understand the list I gave (looked it up), then they (all though they could use ifstream/ofstream) they would not understand how it works.
File objects are like every thing else in C++ (only more so!), you need to know 10x as much as you do inorder to do the same thing in C; or to put it anouther way, you are offten - shooting in the dark.
C is straight forward, either you do it right or you do not; there is no in-between.
Do not get me wrong, I love C++ (up to a point). But, it hides to much of the details.
I am a believer in the KISS principle and C++ is based on the the KIC (keep it coplicated) principle.

Man, I just find that comment bizarre. An instance of an object that exposes an interface is harder to understand than a set of functions that pass handles around ? Besides, all the source code is provided, nothing is hidden.

ROTFL. Well, you're entitled to your opinion.

No, object orientation is based exactly on the idea of keeping it simple, something C finds difficult. The standard library could certainly be easier to learn, but if someone is going to use C++, it's well worth their time to learn it. Once you understand how it works, it is indeed simple, it's also powerful, and extensible to boot. It's certainly a lot nicer than ugly C file handling, at least in my not so humble opinion. It's a pet peeve that ignorant professors teach C with classes instead of C++, meaning that far too many people have no idea the standard library even exists.

If you find the statement that you need to know 10x as much in C++ than you need to know in C, then we need to talk. (When you look at a C-program, you know what is going to happen. When you look at a C++-prgram, you assume what is going to happen.)
Example:
for( object i=0; i != end; i++ )
What is wrong with the above example? In C (except for the term object) nothing.
C++ is great, but it hides so much that it is rediculus. I, like most peaple, ignore the details (a good part of the time), but the details is what distinguashes those who know and those who don't.

Some-thing has went-very wrong here! But I'll leave the above post alone (even though; the posting software, appears to have lost its mind.

Is this sniffer program a console application? If so, its output can be redirected to a file from the command prompt like:
sniffer.exe > output.txt
If you need something a little more advanced, check out this and this.

I tried FMOD function that calculates floating-point remainder of division of two double v1,v2, but with v1 = 17.2 and v2 = 0.1 returns value f = 0.1 instead of f = 0.0.
Someone know why FMOD returns f = 0.1 ?
Thank you.

The problem is floating-point precision.
The floating-point system is based on exponent 2, that causes problems when encoding exp-10-digits.

I'm adding IPv6 functionality to an application that has been designed to monitor the hosts by sending periodical ICMP packets (pings).
According to MSDN and the checkv4 utility, the addrinfo structure should be used, which works well when calling Icmp6SendEcho2[^] , however the problems arise when calling the IcmpSendEcho2 [^], because the fifth argument, the DestinationAddress is IPAddr struct type.
So the real question is: Are there any fuctions that will convert an addrinfo structure to an IPAddr or is there another way of doing this? (Using a bunch of if/else statements to check for IPv4/6 is not an option)

Declare a new address type like this:
typedef struct _SOCKADDR_IPv4v6
{
union
{
sockaddr_in addrv4;
sockaddr_in6 addrv6;
};
} SOCKADDR_IPv4v6, *PSOCKADDR_IPv4v6;
SOCKADDR_IPv4v6 addr;
Icmp6SendEcho2( ..., &addr.addrv6, ... );
IcmpSendEcho2( ..., addr.addrv4.sin_addr, ... );

hi,
i'm trying to add-in the openvc.dll but i get the follwoing error:
"Unable to register this add-in because its DllRegisterServer returns an error"
i'm running VS6.0 on WindowsXP (SP2). not sure of the VS's service pack.
any ideas anyone?
cheers.

Can register openvc.dll from a command prompt? If you can, it is a problem with VS. If you cannot, it is a problem with the DLL itself.

Hi
I will create a connection between two computer using WINSOCK.OCX, but i don't know how can i accept a connection request after listening a port.
In other words, when i become a connection request, i call accept method of IMSWinsockControl, but the connection will aborted immediatly from remote host and connection will be closed.
I will be thankful if everyone can help me.

In C++ I would strongly recommend avoiding the Winsock control. It's designed for environments like Visual Basic that can't do multithreading and as such is a real pain to use for connection-oriented sockets.
Instead I'd recommend that you just use the Windows Sockets library directly.
A useful resource is the Winsock Programmer's FAQ[^].

Where is this information stored ?
Is there an interface to access it ?

If you have a handle to the window, you can use GetWindowRect().

How is XP/2000 WDM driver code different from WIn98SE WDM/WIn95 OSR2.1 WDM?
Tell ME why
|

Win95 does not support WDM!
Win98 supports WDM, but there are slight differences between Win2k/XP and Win98.
Don't try it, just do it!
