How to improve my code about finding all the word files(*.doc) in D

void CMOVEDlg::CopyFile(CString destdir)//destinaton directoty is E
{
    CFileFind tempFind;
    CString tempFileFind;
    tempFileFind.Format("%s\\*.doc",destdir);
    BOOL IsFinded=(BOOL)tempFind.FindFile(tempFileFind);
    while(IsFinded)://when no word file(*.doc) in the based directoty in D, bWorking is wrong and can't come into the while loop.But I want to find and copy all doc file in D.What should I do?

    {
      IsFinded=(BOOL)tempFind.FindNextFile();
      if(!tempFind.IsDots())  
      {
         CString foundFileName;
         foundFileName=tempFind.GetFileName();

         if(tempFind.IsDirectory())
         {
            CString tempDir;
            tempDir.Format("%s\\%s",destdir,foundFileName);
            CopyFile(tempDir);
         }
         else
         {
            CString tempFileName1,tempFileName2;
            tempFileName1.Format("%s\\%s",dir,foundFileName);
            tempFileName2.Format("%s\\%s",m_Path,foundFileName);
            ::CopyFile(tempFileName1,tempFileName2,FALSE);
         }
      }
    }
    tempFind.Close();
}
