Is it any such interface/header in MSVC++ include library, if it exists, what is it called(the header file)? I want to recieve an char array of existing file names in a directory. any help apprichiated! by the way does this work?: #define MAX_ARRAYS 10 typedef short[MAX_ARRAYS] array; Anton Karlsson Klingis Entertainment Games with silly humor

<windows.h> has the functions "FindFirstFile", "FindNextFile", and "FindClose".

Example code:


#include <windows.h>

#include <string>
#include <vector>

...

std::vector<std::string> findFiles(const string& mask)
{
	std::vector<std::string> result;

	WIN32_FIND_DATA fileData;
	HANDLE search = FindFirstFile(mask.c_str(), &fileData);
	if (search == INVALID_HANDLE_VALUE) return result;

	do
	{
		if ((fileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) == 0)
			result.push_back(fileData.cFileName);
	}
	while (FindNextFile (search, &fileData));

	FindClose(search);

	return result;
}

...

std::vector<std::string> files = findFiles("c:/somewhere/*.txt");

For your other question, try: typedef short array[MAX_ARRAYS];

Can I use a char **array; instead,
cos I want to code in just C.



void find_file_paths(char &**array, char *path)
{
    WIN32_FIND_DATA fileData;
    HANDLE search = FindFirstFile(path, &fileData);
	if (search == INVALID_HANDLE_VALUE) return;
	do {
            if ((fileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) == 0) strcpy(*array++, fileData.cFileName);	
}
	while (FindNextFile (search, &fileData));	FindClose(search);
}

char **array;

find_file_paths(array);

or
#define MAX_FILE_NAME_LENGTH 64
typedef char *FILE_NAME_ARRAY[MAX_FILE_NAME_LENGTH];

Anyway, I will use a struct made of myself called file_data.

struct file_data
{
short id;
short format;
char *path;
char *name;
char *extension;
};

Is string a typedef char *string; ?
