need help with ReadFile need to read in from : to -

Code:

---

#include "stdafx.h"
#include "windows.h"
#include <iostream>
using namespace std;

HANDLE File;
char Buf[128];
char lpbuffer[128];
DWORD dwRead;

int found = 0;
int spaces = 0;
int j = 0;
void check();
void Makeip();
//: 219.128.254.40 -
int _tmain(int argc, _TCHAR* argv[])
{
Buf[127] = '\0';
File = CreateFile("file.txt",GENERIC_READ, 0, NULL ,OPEN_ALWAYS , FILE_ATTRIBUTE_NORMAL , NULL);
   
while(1)
{

ReadFile(File , Buf , sizeof(Buf), &dwRead , NULL);
for(int i = 0; i < sizeof(Buf); i++) //checks through the lenght of the buffer
{

        if(Buf[i] == ':') //theres 2 of these , the txt where i want is after the second :
        {
                found++;
                if(found == 2)
                                    {
                                    //now the text i want to get from the buffer is between : and - but sometimes is in a diferent place on diferent lines so the Buffer array element wont always be in there...

                                    }
                }
}

}
return 0;
}

when you have found the second ':' you will have to append the following data to another buffer ( result ) until you reach the '-':.
Kurt

Apart from the crap indentation, why aren't you using standard stream I/O and standard strings for this?

what do you mean make another
ReadFile(File , Buf , sizeof(Buf), &dwRead , NULL);

but wont that start on the first line at the beginging ?

I was thinking about something like this

Code:

---

char result[100];
char * resp = result;
while(1) {
    ReadFile(File , Buf , sizeof(Buf), &dwRead , NULL);
    for(int i = 0; i < sizeof(Buf); i++) { //checks through the lenght of the buffer
        if(Buf[i] == ':') //theres 2 of these , the txt where i want is after the second :
            found++;
        if(found == 2) {
            if ( Buf[i] != '-' )
                *resp++ = Buf[i];
            else {
                *resp = 0;
            }
        }
    }
}

skipping the first char, range checking and breaking out of the loop is left as an exercise.
Kurt

found has to be reset to 0 so it works again for the next line

I wonder what you are talking about. You never check for a linebreak in this code.
Kurt

the text that i need to grab is in like this

3.8 LME: wordshere - checked , between : and -
dont need anything else copied after it

oh a line break is like '\n' right?

Code:

---

int _tmain(int argc, _TCHAR* argv[])
{
Buf[127] = '\0';
File = CreateFile("part1.txt",GENERIC_READ, 0, NULL ,OPEN_ALWAYS , FILE_ATTRIBUTE_NORMAL , NULL);
   

       

char *result[15];


s:
    ReadFile(File , Buf , sizeof(Buf), &dwRead , NULL);
//        cout << Buf;
        Sleep(50);
        for(int i = 0; i < strlen(Buf); i++)
        {
                if(Buf[i] == ':')
                {
                    found++;
                        if(found == 2)
                        {
                                for(int j = 2; j < 15; j++)
                                {
                                        if(Buf[i+j] == '-' || Buf[i+j] == 'V')
                                        {
                                                break;
                                        }
                                        else
                                        {
                                        cout << Buf[i+j];
                                        sprintf(result[k++] , "&#37;c", Buf[i+j]); //stuck on this part <-------------------
                                        }
                                }
                        }
                }
       
        }

        cout << result << endl;
        found = 0;
        goto s;



return 0;
}

This just goes from bad to worse, now it has goto's to implement a while loop.

First question still stands.
