Scanning a Directory in Visual C++
I need to write a program that compiles several files into one big file so I can do work on that big file. I'm fairly new to windows programming and am having a hard time figuring out how to scan a directory. The directory I need to scan will contain a type of file with a .dat extension and nothing else. I need to find the first file, place it in the bigger file, and then delete it. I can handle putting it in the bigger file and deleting it but I have not had any success scanning the directory and selecting files. Any help would be really appreciated!

Slight modification - ANSI C provides for remove() to delete a file, and, of course, can be called in C++

Let me clarify my original question further by saying that this program is being developed in Microsoft Visual C++ 6.0.

That was the general premise of what I needed to do. Good job! I tweaked the code a little...
#include <iostream>
#include <windows.h>
#include <vector>
#include <string>
using namespace std;
vector<string> ListDirContents(char *path) {
int i=0, files;
vector<string> list;
WIN32_FIND_DATA find_data;
HANDLE hnd;
find_data.dwFileAttributes
if((hnd = FindFirstFile(path, &find_data)) == INVALID_HANDLE_VALUE)
return list; //no flies or error
do
{
list.push_back( find_data.cFileName );
}
while(FindNextFile(hnd, &find_data));
FindClose(hnd);
return list;
}
int main()
{
vector<string> test = ListDirContents("C:\\test\
vector<string>::iterator itr = test.begin();
cout << test.size() << endl;
while( itr != test.end() )
{
cout << *itr << endl;
itr++;
}
return 0;
}
#include <iostream>
#include <windows.h>
#include <vector>
#include <string>
using namespace std;
vector<string> ListDirContents(char *path) {
int i=0, files;
vector<string> list;
WIN32_FIND_DATA find_data;
HANDLE hnd;
find_data.dwFileAttributes
if((hnd = FindFirstFile(path, &find_data)) == INVALID_HANDLE_VALUE)
return list; //no flies or error
do
{
list.push_back( find_data.cFileName );
}
while(FindNextFile(hnd, &find_data));
FindClose(hnd);
return list;
}
int main()
{
vector<string> test = ListDirContents("C:\\test\
vector<string>::iterator itr = test.begin();
cout << test.size() << endl;
while( itr != test.end() )
{
cout << *itr << endl;
itr++;
}
return 0;
}
Here's an example (cut from an earlier EE post) for WINDOWS:
#include <stdio.h>
#include <io.h>
#include <time.h>
void main( void )
{
struct _finddata_t c_file;
long hFile;
/* Find first .c file in current directory */
if( (hFile = _findfirst( "*.c", &c_file )) == -1L )
printf( "No *.c files in current directory!\n" );
else
{
/* do something with file */
/* Find the rest of the .c files */
while( _findnext( hFile, &c_file ) == 0 )
{
/* do something with remaining files */
}
_findclose( hFile );
}
}
