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 '-':.

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.

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.
