Searching for and Reading INIs

You can use FindFirstFile (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/findfirstfile.asp)/FindNextFile (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/findnextfile.asp) to enumerate files/directories on a disk. Then when wanted files are found, you can use GetPrivateProfileSectionNames (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getprivateprofilesectionnames.asp)/GetPrivateProfileSection (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getprivateprofilesection.asp) to enumerate values in the .ini files.

Hrm, I'm having trouble implementing these functions, anywhere I can find sample code thats well commented?

Use "The first file found is %s\n" instead of "The first file found is %x\n", otherwise, it displays the address of the FindFileData.cFileName string buffer.

Actually, correct me if I'm wrong but %d returns decimal value, %x returns hex value and %s returns string value?

The word "return" is not exact.
It is better to say : %d outputs a decimal value, %x outputs an hex value and %s outputs a string value.

printf does not know the type of the parameters that are passed to it.
printf interprets its arguments, depending on the format string.

If it sees %x, he interprets the argument as an integer, and outputs it in hexadecimal format.
If it sees %d, he interprets the argument as an integer, and outputs it in decimal format.
If it sees %s, he interprets the argument as a pointer to an array of characters, and look at the data pointed, outputing each character pointed to, until it reaches a '\0' character.

Knowing that a string is just a pointer to a character array, arbitrary terminated by a '\0' character, and knowing that a pointer is just an address (whose size is often 4 bytes), we can deduce that printf("%x",FindFileData.cFileName); outputs (in hex format) the address of the first byte of the character array which represents the string.

C++ has iostreams, which don't need an explicit format specifier. :)
But, your program appears to be a C program. You can still learn C++ :D :lol:

My code now looks as

#define _WIN32_WINNT 0x0501

#include <windows.h>
#include <string.h>
#include <stdio.h>

int main()
{
char findFile [80];
WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE;
char DirSpec[MAX_PATH + 1];
DWORD dwError;

printf ("Enter file to find: ");
scanf ("%s",findFile);
strncpy (DirSpec, findFile, strlen(findFile)+1);
strncat (DirSpec, "\\*", 3);

hFind = FindFirstFile(findFile, &FindFileData);

if (hFind == INVALID_HANDLE_VALUE)
{
printf ("Invalid File Handle. Error is %u\n",
GetLastError ());
return (-1);
}
else
{
printf ("The first file found is %s\n",
FindFileData.cFileName);
while (FindNextFile(hFind, &FindFileData) != 0)
{
printf ("Next filename is %s\n",
FindFileData.cFileName);
}

dwError = GetLastError();
FindClose(hFind);
if (dwError != ERROR_NO_MORE_FILES)
{
printf ("FindNextFile error. Error is %u\n", dwError);
return (-1);
}
}
return (0);
}

Which works well in finding multiple files in the directory that I specify but it doesn't go into any subdirectories, is there a way to change that?

Got many errors when trying to compile that code, Golanshahar
