How do I get a list of files in a directory in C++?

Question

How do you get a list of files within a directory so each can be processed?

Answer 1

You can use the following code for getting all files in a directory.A simple modification in the Andreas Bonini answer to remove the occurance of "." and ".."

CString dirpath="d:\\mydir"
DWORD errVal = ERROR_SUCCESS;
HANDLE dir;
WIN32_FIND_DATA file_data;
CString  file_name,full_file_name;
if ((dir = FindFirstFile((dirname+ "/*"), &file_data)) == INVALID_HANDLE_VALUE)
{
    errVal=ERROR_INVALID_ACCEL_HANDLE;
    return errVal;
}

while (FindNextFile(dir, &file_data)) {
    file_name = file_data.cFileName;
    full_file_name = dirname+ file_name;
    if (strcmp(file_data.cFileName, ".") != 0 && strcmp(file_data.cFileName, "..") != 0)
    {
        m_List.AddTail(full_file_name);
    }
}
