This is what I tried and it worked absolutely fine for me. In my previous post, I have attached the output I got too!

Please check if you are doing anything different. or whether it is due to the IDE.

I JUST replaced cout statement with write method. Have a look at the code and tell me if this satisfies your requirements.

no it's not working...

can u plz explain me the operation of if loop...

[AmitTheInfinity]

if(print_buffer!=NULL&&((*print_buffer)==buffer[0]||((*(print_buffer-1))==' ' || (*(print_buffer-1))=='\t'))) 

here, first condition is verifying whether pointer is NULL, this pointer will be NULL in case if the line does not have string "//" in it [result of function strstr].

if it is NULL then we don't need to print anything. if it is not NULL then may be we have a comment on that line.
Now it can be a comment starting at start of line or starting in between. if it starts at index 0 then it is surely a comment
but if it is in between then we have to have some checks.

like printf("//Is this a comment?"); we can not consider this line as comment but our program might. so we added last two conditions to verify this. Though there are few cases where we miss out the comments from the program.

see here printf("//Is this a comment?"); //That was not but this is and program won't catch it!!! yes, our program misses this comment as the comment is at the second occurrence of "//" and we check only first one. So there are chances of improvement too.

I hope this will help you.

Is it possible to read data's send from the webserver using port's to be stored in a text file

[priyashe]

I had created a project in vb in which using socket connection we'll connect with the web server and send data's to the server by giving ip address and now i have to store it in text file is it possible/,,,

Seems that your question is VB related and not connected to this topic. Please post is as a new topic in VB forum in that case. It will make more sense to people here.

[priyashe]

thanx for u'r reply but is it possible in c++

[gabehabe]

Yeah~ Look up ifstream.

Here's a quick sample:

#include <fstream>
#include <iostream>

using namespace std;

int main ()
{
    ifstream infile;
    infile.open ("C:\\dev-cpp\\Untitled-2.cpp");
    if (!infile.is_open()) // check if the file is open
    {
        cout << "Error~ file could not be opened. Aborting";
        cin.get();
        return EXIT_FAILURE; // failed execution
    } // otherwise, we can now assume that the file is open from here on in:
    char buffer; // a character buffer, to read it character by character
    while (!infile.eof()) // while the end of the file has not been reached
    {
        infile.get(buffer);
        cout << buffer;
    }
    cin.get();
    return EXIT_SUCCESS;
}

NOTE: I just typed this in less than a minute in only the fast reply box~ there may be a few errors/typos in there.

Hope this helps
