Well I don't think author meant any of two things you mentioned.

Hi !
I am complete pure win32/C++ Guy . I want to Migrate to Visual C++.net.
I saw so many books everything telling for .Net with C# or .Net with Vb or aDO.net or asp.net like that
But I need C++ to Visual C++.net style.
Which is the book for beginning?
Please suggest

Why?
I mean: remain stuck with C++ for unmanaged applications and use C# for managed ones.

I was trying to figure out the code written by Tejpal Singh Chhabra on back-propagation in c++. I liked the code but I cant understand why three dimensional array is used for allocating weight.Can anybody please explain me logic behind this.I am bad in pointers.
Thanks in advance.
|
|
|
|

I have no idea about the code, or the problem as such, but if they're allocating a 3d array to store weight values, I'd strongly guess it's because the weight is a function of 3 independent variables?
Say you like a certain combination of cars.
BOOL MyLiking [NUMBEROFCOLOURS][NUMBEROFDOORS][NUMBEROFMANUFACTURERS];
...
MyLinking [RED][2][NUM_SKODA] += 50;
MyLinking [BLUE][4][NUM_BMW] -= 50000;
...
}
I hope that makes a littttttttle bit of sense.

I need to change the TOS field of all packet I send. I am not use to program I do not success to make operated this code.
<br />
WSADATA WSAData; <br />
WSAStartup(MAKEWORD(2,0), &WSAData); <br />
<br />
SOCKET sock; <br />
SOCKADDR_IN sin; <br />
sin.sin_addr.s_addr = inet_addr("192.168.4.33");<br />
sin.sin_family = AF_INET;
sin.sin_port = htons(10000);
<br />
sock = socket(AF_INET, SOCK_RAW, 0); <br />
bind(sock, (SOCKADDR *)&sin, sizeof(sin));
<br />
int TOS=0x80; <br />
<br />
while(1)<br />
{<br />
setsockopt(sock, IPPROTO_IP, IP_TOS, (char *)&TOS, sizeof(TOS));<br />
<br />
if (setsockopt(sock, IPPROTO_IP, IP_TOS, (char *)&TOS,<br />
sizeof(TOS)) == SOCKET_ERROR)<br />
printf("\nWarning: Fail to set TOS value: error - %d",<br />
WSAGetLastError());<br />
} <br />
system("PAUSE");<br />
return EXIT_SUCCESS; <br />
}<br />
Someone would have a solution? I just try to modify TOS field at the value 0x80 using the function setsockopt().

So do you know an other issue to mark all TOS IP header fields from all outcoming packets?

which is the best way to read a line from a text file in c.. the size is not known. and this text needs to be stored in a CString.
|
|

If you're reading it in C, then you can't store it in a CString (C++).
For MFC, you can use CStdioFile and its member function ReadString.
In C, it's a bit harder - you have no idea about the buffer length for your TCHARs (you are using unicode compatible code, I hope...), so you're going to have to keep the current file pointer, read through the file until you hit the end, or a carriage return, calculate the size, rewind, then read the string.
Or read the whole file into memory, and act on it as a big chunk of ram, which will be similar, but faster.
And now someone will come along and tell you to use
WinReadStringFromFile (...); (Made up name, before you look for it)
Good luck,
Iain.

That would all depend on how the file was opened.

Unless the file is still being written to, how can you not know its size?

Hi,
What is the difference between
#include "math.h" and
#include <cmath> </cmath>
and which is better?
Thanks & Regards,

first remove HTML support from your question!
#include<math.h> search for file in path configured in project setting/development env setting
#include "math.h" also search current directory including project/ developement env setting

Maybe a minor difference, using the quotes the searches first in the current directory and then in the project/ developement env setting.
This means that you can overrule include files
