Recursive directory search

Hello

Trying to write a recursive function (my first) to search directories for files that meet a criteria. I’m nearly there ,but I can’t get the function to list the content of a directory when it find one. I have been staring at this problem for hours but I can’t see the flaw.

A nugde in the right direction would be gratefully apprepricated

Regards

Hmm

The code:

#include <iostream>
#include <fstream.h>
#include <windows.h>
#include <string.h>
using namespace std;

bool FindFiles(char *pFiles,HANDLE handle);

int main(){

char *dir = "C:\*";
HANDLE hFile;

FindFiles(dir,hFile);
return 0;
}

bool FindFiles(char *pFiles,HANDLE handle){

WIN32_FIND_DATA fData;
char buf[200],TmpPath[MAX_PATH],Buffer[MAX_PATH],*pBuffer;
pBuffer=Buffer;


if ((handle = FindFirstFile(pFiles,&fData))==INVALID_HANDLE_VALUE){
wsprintf (buf, "Error code %d", GetLastError() );
return 0;
}


while (FindNextFile(handle,&fData)!=0){
if((fData.dwFileAttributes==FILE_ATTRIBUTE_DIRECTORY)!=0 && strcmp(fData.cFileName,"..")){
GetCurrentDirectory(MAX_PATH,TmpPath);
FindFiles(strcat(TmpPath,"\\*.txt"),handle);
}

strcpy(Buffer,fData.cFileName);
std::cout << pBuffer << std::endl;

}
FindClose(handle);
return 0;
}

I made a few changes and this should now display the files and folders in C:\. You will need to play around with the code to get the recursion effect that you want however.

#include <iostream.h> 
#include <fstream.h> 
#include <string.h> 
#include <windows.h>
 

bool FindFiles(char *pFiles,HANDLE handle); 

int main(){ 

char *dir = "C:\\*.*"; 
HANDLE hFile=0; 

FindFiles(dir,hFile); 
return 0; 
} 

bool FindFiles(char *pFiles,HANDLE handle){ 

WIN32_FIND_DATA fData; 
char buf[200],TmpPath[MAX_PATH],Buffer[MAX_PATH],*pBuffer; 
pBuffer=Buffer; 


if ((handle = FindFirstFile(pFiles,&fData))==INVALID_HANDLE_VALUE){ 
wsprintf (buf, "Error code %d", GetLastError() ); 
return 0; 
} 


while (FindNextFile(handle,&fData)!=0){ 
if((fData.dwFileAttributes==FILE_ATTRIBUTE_DIRECTORY)!=0 && strcmp(fData.cFileName,"..")){ 
GetCurrentDirectory(MAX_PATH,TmpPath); 
FindFiles(strcat(TmpPath,"\\*.txt"),handle); 
} 

strcpy(Buffer,fData.cFileName); 
cout << pBuffer << endl; 

} 
FindClose(handle); 
return 0; 
}
