if you want to get files or folders if you use ListBox see DlgDirList and use m_ListBox.GetCount()

here is the sample snippet

CFileFind finder;
 BOOL bWorking = finder.FindFile("*.*"); // give full path, else it will search in the current directory
 while (bWorking)
 {
    if (finder.IsDots())
       continue;

    // if it's not a directory, add it
    if (!finder.IsDirectory())
    {
        bWorking = finder.FindNextFile();
        m_ListBox.AddString((LPCTSTR) finder.GetFileName());
    }
 }

Another way to do the same thing

// The pointer to my list box.
extern CListBox* pmyListBox;

// Add all the files and directories in the windows directory.
TCHAR lpszWinPath[MAX_PATH], lpszOldPath[MAX_PATH];
::GetWindowsDirectory(lpszWinPath, MAX_PATH);

::GetCurrentDirectory(MAX_PATH, lpszOldPath);
::SetCurrentDirectory(lpszWinPath);

pmyListBox->ResetContent();
pmyListBox->Dir(DDL_READWRITE|DDL_DIRECTORY, _T("*.*"));

::SetCurrentDirectory(lpszOldPath);

	POSITION currPos;


	char strFilter[] = { "Mp3 files (*.mp3)|*.mp3|All Files (*.*)|*.*||" };

	CFileDialog avi(TRUE, ".mp3",NULL,OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY, strFilter);

    char drive[_MAX_DRIVE], middle[_MAX_PATH], filename[_MAX_FNAME], ext[_MAX_EXT];


     if(avi.DoModal() == IDOK)
	 { 

   currPos = avi.GetStartPosition();

     while(currPos != NULL)            
					
	 {
  m_SongName = avi.GetNextPathName(currPos);
_splitpath (m_SongName, drive, middle, filename, ext);
m_list7.AddString(m_SongName);

so tell atleast what modufication i should do to ad folder

Use SHBrowseFolder for selecting folder.

it is easy to modify the snippet i have given.

After this,

TCHAR lpszOldPath[MAX_PATH];
::GetCurrentDirectory(MAX_PATH, lpszOldPath);
::SetCurrentDirectory(csFolderSelecter);

pmyListBox->ResetContent();
pmyListBox->Dir(DDL_READWRITE|DDL_DIRECTORY, _T("*.mp3"));

::SetCurrentDirectory(lpszOldPath);

This will work fine Smile | :)

2. Right click on the class and select "Add Message Handler"

one simple way insert this codes in your file(I think you need to learning VC)but anyway for solve your problem use this
in header file
afx_msg BOOL OnEraseBkgnd(CDC* pDC);

in cpp file insert

 <br />
BOOL your class name::OnEraseBkgnd(CDC* pDC) <br />
{<br />
// TODO: Add your message handler code here and/or call return CDialog::OnEraseBkgnd(pDC);<br />
}<br />

Depending on the class type (e.g. Dialog, MDI Child Frame, etc.), ClassWizard filters the messages.

To show all messages do the following:

select "Class Info" tab;
from "Message filter" combo box, choose "Window";
go back to "Message Maps" tab; now all available messages are displayed in the "Messages" list.
