FindFile class for Windows projects

This class is intended to alleviate the task of finding files and folders in a directory with options such as search filters; exclude file filters, exclude directory filters

Introduction

Searching for files and directories is something we, as programmers, have to do in many projects. I have always thought that there must be something someone out there wrote to make my life easier in this regard. I have done a lot of looking around but most of what I've found has had a dependency on a specific IDE, like VS and MFC for example. So, I decided to write my own, make it IDE independent and add some useful features. FindFile, is the result of my efforts.

Using the code

The code that allows searching consists of the files FindFile.h, FindFile.cpp, wildcard.h, and wildcard.cpp. To use the code, you need to initialize a FindFileOptions_t structure and pass it by reference to the constructor of FindFile. Here is a snippet of the structure, listing options used by FindFile:

struct FindFileOptions_t
{
    bool recursive;         // Whether to look inside subdirectories
    bool returnFolders;     // Return folder names as results too

    bool *terminateValue;   // Value to check to see whether search 
                            // should be terminated

    string location;        // Where to search for files

    string filter;          // Filter for files to be included

    string excludeFile;     // Exclude filter for files
    string excludeDir;      // Exclude filter for directories
};

Some of these options require explaining. The returnFolders option specifies whether FindFile should return both files and directories in its return results. The terminateValue option is a pointer to some integer in memory whose value will be read to determine whether the search should be aborted. This is useful to have when incorporating this class in a multi-threaded environment (as is most likely the case). If the value in the integer pointed to by terminateValue is anything but 0 the search will abort. If you do not want to use this feature, just set terminateValue to NULL.

Here is an example of a program that uses FindFile:

    FindFileOptions_t opts;
    opts.excludeDir = "CSE*;*53*";
    opts.excludeFile = "*.pdf;*.doc";
    opts.filter = "*";
    opts.location = "C:\\School";
    opts.recursive = true;
    opts.returnFolders = false;
    opts.terminateValue = NULL;

    FindFile find(opts);
    find.search();

    int nfiles = (int) find.filelist.size();
    __int64 size = find.listsize;

    // Print out the list of files found
    for (int i = 0; i < (int) find.filelist.size(); i++)
    {
        string fullname = FindFile::combinePath(find.filelist[i].path, 
                       find.filelist[i].fileinfo.cFileName);
        printf("%s\n", fullname.c_str());
    }

    printf("Found: %d files (%ld bytes)", nfiles, size);

This example will recursively search for all files in directory "C:\School" which do not have a PDF or DOC extension and will not look for files in subdirectories that begin with "CSE" or contain "53".

hmm...I have changed the code to look exactly as you've shown....for some reason it still hangs when I am trying to run a search.

if it's a valid handle, return true....what does that mean? return where? and what does it do if it's not a valid handle? I just don't see how that check helps or does anything.
if you return true, won't that exit the "getfile" function....and stop the recursion etc...??
