Hi folks,
I'm having problems with my loops, and possibly more...hehe!
I'm loading a text file, which has 1 word per line, into a buffer and I want to search the buffer for all the words that start with the same prefix (3 letters) and return the words in an edit box.
I successfully accomplished reading 1 line, compare the prefix, and show the word in an edit box if prefix matches. Now, I'm just stuck with making it loop.
EXEMPLE:
The Prefix is: "Bla".
The text file contains:
Benji
Bennett
Bentley
Beverly
Billy
Birch Grove
Birch Hill
Birch
Birchdale
Birchmount
Birchwood
Black Beach
Black
Blair
Bleury
Blue Heron
Blue Rock
The program will return:
Black Beach
Black
Blair
Here's the code for the button:
#include <iostream>
#include <fstream>
#include <strstream>
....
void Csn3Dlg::OnBnClickedButton1()
{
UpdateData(TRUE);
FILE * pFile;
char buffer [20];
CString prefix = "Old";
CString readprefix;
CString temp;
CString read;
int count=0;
pFile = fopen ("/forum/dnamelist.txt" , "r");
if (pFile == NULL)
{
MessageBox("Error opening file", NULL, MB_OK | MB_ICONSTOP);
exit(0);
}
else
{
while ( ! feof (pFile) )
{
fgets (buffer , 20 , pFile);
fputs (buffer , stdout);
read = read+buffer+"\r\n";
}
fclose (pFile);
//My problems are in there:
while ( prefix != readprefix )
{
for (int j = count ; read[j]!='\n'; j++)
temp = temp+read[j];
for(int k=0 ; k!=3 ; k++)
readprefix = readprefix+temp[k];
if(prefix == readprefix)
break;
else
count++;
}
m_out = temp;
}
UpdateData(FALSE);
}

Any suggestions or help will be much appreciated!
