list files in directory
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. ?????

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;}
