Copy Files And Directories By Traversing

Introduction

I have searched many sites in Google but was not lucky enough to find a code snippet which is used for copying files using traverse algorithm. I got it after a little effort and I want to share it with friends out there. It is simple and I am including the code snippet below. This is my first submission here.

The Code

This comes under the button click:

void CCopyFilesFrmFoldersDlg::OnButCopy() 
{ 
 CString csSourceDir(_T("")), csDestDir(_T("")); 
 UpdateData(TRUE); 
 GetDlgItemText(IDC_EDIT_SOURCE, csSourceDir);
 GetDlgItemText(IDC_EDIT_DEST, csDestDir); 
 CopyDirAndFiles(csSourceDir, csDestDir);
}

This goes in the function CopyDirAndFiles:

bool CCopyFilesFrmFoldersDlg::CopyDirAndFiles(CString csSource, CString csDest)
{
 bool bReturn  = false; 
 
 try
 {
  CFileFind oFileFind; 
  CString csSourceFilePath(""),csDestFilePath("");
  int nSym(0), nTot(0);
  CString csTemp(""); 
  csSourceFilePath = csSource;
  csSourceFilePath += "\\*.*";
  
 /////////start looping////////
  BOOL bWorking = oFileFind.FindFile(csSourceFilePath);
  
  while (bWorking)
  {   
   ////////////Search for next file///
   bWorking = oFileFind.FindNextFile(); 
   ///////////File Path Name//////////
   csSourceFilePath = oFileFind.GetFilePath(); 
   if(oFileFind.IsDirectory())
   {      
    if(oFileFind.GetFileName().CompareNoCase(".")==0||
		oFileFind.GetFileName().CompareNoCase("..")==0)
    continue;   
    csDestFilePath = csDest;
    nSym = csSourceFilePath.ReverseFind('\\');
    nTot = csSourceFilePath.GetLength();    
    csTemp = csSourceFilePath.Right(nTot - nSym);    
    csDestFilePath += csTemp; 
    CreateDirectory(csDestFilePath, NULL); 
    CopyDirAndFiles(csSourceFilePath, csDestFilePath);
   }
   else
   {    
    csDestFilePath = csDest;
    nSym = csSourceFilePath.ReverseFind('\\');    
    nTot = csSourceFilePath.GetLength();    
    csTemp = csSourceFilePath.Right(nTot - nSym);    
    csDestFilePath += csTemp;
    
    CopyFile(csSourceFilePath, csDestFilePath, FALSE);
   }
  }
  
  oFileFind.Close();  
  bReturn = true;
 } 
 
 catch(...)
 { 
  bReturn = false;
 } 
 
 return bReturn;
}

Hope it helps...
