Is there a way in c/c++ (mfc or not) to list the files in a directory? Thx in advance. P.S. I disassembled one of my programs and found out that a signed integer (2 bytes) was offset from the next one by 4 bytes. ????? Here comes the Thnikkaman!

Neither C nor C++ supplies any operating system independent method of listing the files in a directory. For Win32, you can try looking up the FindFirstFile() family of functions. Alternately you can try boost::filesystem.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

string array[100];

void ClearArray()
{
for(int i=0;i<100;i++){
array[i] = "";
}
}

void LoadDir(string sDir)
{
string buff;
buff = "Dir " + sDir + " /aa /b >> c:\\d.txt";
system(buff.c_str());
}

void LoadArray()
{
fstream tmp;
tmp.open("c:\\d.txt" );
int i = 0;
while(!tmp.eof()){
tmp >> array[i];
i++;
}
tmp.close();
}

void ListArray()
{
for(int i=0;i<100;i++){
if(array[i] == "" ){ break; }
cout << array[i] << endl;
}
}

int main()
{
ClearArray();
LoadDir("C:\\" );
//LoadDir("c:\\games\\" );

LoadArray(); // load array with directory listing.

ListArray(); // dumb array to console.

ClearArray(); //clean up global array.

system("del c:\\d.txt" ); //destroy tempory directory list file.

return 0;
}
