Now, I only need to add the function of process that will parse each block within the while loop rigth?

I'd like to parse each block using regex.

---

What parsing of the block do you require?

Hello AceInfinity,

Thanks for try to help me too. I'll test your code either.

Hello 2kaud,

For each block I'd like first to extract some patterns with 2 regex below.
Regex1: (.{6,18})(532064[^f]*).(814[^f]*)
Regex2: ff79(0080.{4}c906)?.*?05(9.{32,34}.*?)940e(.{28})

Regex1 matches string in red
Regex2 matches string in blue

Code:

Regex1 works to extract data from the beginning of the block, for block 2 Regex1 would get:

Code:

---

00000253206445018934551f81474554768

---

but since I'm grouping with backreference, this string would be splitted like this

Code:

---

000002,53206445018934551,81474554768

---

to finally treat as hex the first group and print as decimal, leaving group 2 and group 3 without change as below.

Code:

---

2,53206445018934551,81474554768

---

For Regex2, I'm using backreference too, since I only want to extract the group 2 and 3 from Regex2. But the
parsing of string got from Regex 2 is more complicated. So, Initially I'd like to know how to apply regex on each
block.

Many thanks for the help

regex is part of c++11

http://www.cplusplus.com/reference/regex/

Hello 2kaud,

Thanks for that.

I've tried to add <regex> header but I receive error. I've read that maybe with visual studio compiler could work.

I've downloaded and installed a visual C++ 2012 compiler version but I'm no able to make that works with netbeans nor Dev C++.

Does accepts for you the regex header? Which IDE and compiler are you using?

Thanks in advance

I'm using VS 2013 and am able to use the <regex> header with this setup. Dev C++ is old (assuming you're using bloodshed's, and not orwells), and if so, you should abandon it.

Thanks for the answer.

I'm testing with netbeans and Orwells Dev C++.

Since MSVS is payed, do you know another IDE or compiler that let me use regex?

Thanks again

You're assuming that it's a paid software. There are express editions of Visual Studio for 2013 which are free.

Hello Ace

I've installed MSVS 2013 and I've been trying to test regex using the example for the below page, bu I get errors when
compile.
http://en.cppreference.com/w/cpp/reg...ax_option_type

I'm not sure why, I did this: New project --> Visual C++-->CLR-->CLR Console Application.

CLR, why do you want that? Try "Win32 Project" instead. What errors are you getting? You just posted a reference link, but nothing that describes the errors.

gcc is free and is c++11 compliant
http://gcc.gnu.org/

(see top of news left hand side regarding support for regex!)

Thanks!. Only I didn't know what option to choose. I'll test as you say.

Thanks 2kaud, I'll try to download and see if I'm able to make it work this compiler.

Thanks again for the help.

Hello 2kaud

I've been searching and it seems gcc doesn't support yet regex :(. It seems only basic things.

http://gcc.gnu.org/projects/cxx0x.html
http://gcc.gnu.org/onlinedocs/libstd...tatus.iso.200x

I found that clang is full C++11, but it seems it works for linux. I'll continue searching.

Hello 2kaud again,

I see that each block is printed in the for loop using "display(bv)", but I'd like to store in a single string each block
to be able to process it. I'd like to modificate the display function in order to have in a string each block, something like
below but I don't know how would be the correct way and how to retrieve that string in main function.

Code:

---

void display(const bVec bv)
{
        for (int i = 0; i < bv.size(); i++)
                //cout << setw(2) << setfill('0') << hex << (int)bv[i];
            Block= Block + (int)bv[i];
}

---

I hopw you can help me with this.

Thanks in advance.

bv is a vector of BYTE (unsigned char) that can be processed. If you want a string of hex equivalent then one way is

Code:

---

void display(const bVec& bv)
{
        for (int i = 0; i < bv.size(); i++)
                cout << setw(2) << setfill('0') << hex << (int)bv[i];
       
        cout << endl << endl;
}

void conString(const bVec& bv, string& block)
{
ostringstream ss;

        for (int i = 0; i < bv.size(); i++)
                ss << setw(2) << setfill('0') << hex << (int)bv[i];

        block = ss.str();
}

int main()
{
FileFields        ff;

bVec        bv;

int blk = 0;

string block;

        if (!ff.open("binary.txt")) {
                cout << "Cannot open file!" << endl;
                return 1;
        }

        while (ff.getField(bv)) {
                cout << "block " << blk++ << endl;
                //display(bv);
                conString(bv, block);
                cout << block << endl << endl;
        }

        return 0;
}

Hello 2kaud,

Thanks for your help. Ive tried but in compilation I get the error:

Code:

---

[Error] aggregate 'std::ostringstream ss' has incomplete type and cannot be defined

---

I've added "std::" but the same error.
