Scans a folder for sub-folders and files. Simple and easy to use.

Introduction

CSADirRead is a class that will generate a list of files and folders contained in a folder of your choice.

Usage

First, declare a CSADirRead object

#include <span class="code-string">"SADirRead.h"</span>

...

CSADirRead dr;

First, we build our list of folders to scan.

dr.ClearDirs();         // start clean
dr.GetDirs("c:\\temp", true); // get all folders under c:\temp

// dump the directory list to the debug trace window:

// get the dir array
CSADirRead::SADirVector &dirs = dr.Dirs();

// loop over it
for (CSADirRead::SADirVector::iterator dit = dirs.begin(); 
     dit!=dirs.end(); dit++)
{
    TRACE("%s\n", (*dit).m_sName);
}

Now that the object knows which directories to scan, tell it to scan for files:

dr.ClearFiles();        // start clean

dr.GetFiles("*.jpg");   // get all *.JPG files in c:\temp and below

// get the file array
CSADirRead::SAFileVector &files = dr.Files();   

// dump it...
for (CSADirRead::SAFileVector::iterator fit = files.begin(); 
     fit!=files.end(); fit++)
{
    TRACE("%s\n", (*fit).m_sName);
}

Because you can access and modify the folder list before scanning for files, you can manually add folders to (or remove folders from) the folder list. Likewise, you can call GetDirs() multiple times to build up the folder list before scanning for files, like this:

dr.ClearDirs();                   // start clean
dr.GetDirs("c:\\temp", true);     // get all folders under c:\temp, recursively
dr.GetDirs("c:\\windows", false); // look in c:\windows. but don't recurse 
                                  // to sub-folders

dr.ClearFiles();
dr.GetFiles("*.JPG"); // gets files from all of the above folders

Sorting the results

After building the file list, you can sort the files using CSADirRead::SortFiles. CSADirRead has three built-in sorting methods - alphabetic, date and size - and can sort in ascending or descending order.

Get a list of subfolders in c:\windows

CSADirRead dr;
dr.GetDirs("c:\\windows", false);
dr.GetFiles("*.*", false, true);
 
// get the file array
CSADirRead::SAFileVector &files = dr.Files();   

Now, files will have a list of subfolder of C:\Windows (no files included, just the folders)

Questionhow to get path to my own executable? PinmemberJesse Evans4-Feb-03 11:34 
Hi, folks...
I have a design which requires maintaining several .ini files, both local to the app and on a server for global settings. I'm using SHBrowseForFolder in a dialog to build a path to my global files, which then needs to be saved in the local file. I use a relative filename for my local file, so that I can always find it regardless of where my executable is launched from. However, when I use the folder browser, the local filename gets appended to the path returned by the folder browsing activity and the local file gets written relative to the global path.
 
How can I determine the path within which my application has been executed from, so that I can easily get to its local .ini file?
 
Thanks! Jesse
