Program Layout:

Cedit = m_strFile   // Prints the path of the file which contains the album (mp3's)
ComboBox = m_ComboBands // A list of bands
List Control = m_MyAlbums // the name of the bands albums
Button1 = Browse
Button2 = Rename
Button3 = Stop

What this program does is... once a file is selected. You then select which band it is on the comb box and then the list control shows the current bands album names, after selecting one you press rename and it renames the mp3's in the selected file.

Since you have an idea of my program. I have been having problems with getting the selection of the combo box to the list control. After compileing my code, i select a 311 and it displays both 311 and Adema. Please help me!

Heres my code.....

void CMp3RenamerDlg::OnSelchangeCombo1()
{
     char nSelection = m_ComboBands.GetCurSel();

     if( nSelection != LB_ERR )
     {
          if( nSelection, "311" )
          {
                                            m_MyAlbums.DeleteAllItems();
                m_MyAlbums.InsertItem(0, _T( "Music" ));
                m_MyAlbums.SetItemText(0,1, "1993");
               m_MyAlbums.InsertItem(0, _T("Self Titled"));
               m_MyAlbums.SetItemText(0,1, _T("1996"));
                 m_MyAlbums.InsertItem(0, _T("Transistor"));
                m_MyAlbums.SetItemText(0,1, _T("1997"));
               m_MyAlbums.InsertItem(0, _T("Live"));
               m_MyAlbums.SetItemText(0,1, _T("1998"));
                m_MyAlbums.InsertItem(0, _T("Soundsystem"));
                m_MyAlbums.SetItemText(0,1, _T("1999"));
               m_MyAlbums.InsertItem(0, _T("Grassroots"));
               m_MyAlbums.SetItemText(0,1, _T("2000"));
                m_MyAlbums.InsertItem(0, _T("From Chaos"));
                m_MyAlbums.SetItemText(0,1, _T("2001"));
               m_MyAlbums.InsertItem(0, _T("Evolver"));
               m_MyAlbums.SetItemText(0,1, _T("2003"));
          }
          if( nSelection, "Adema" )
          {
                                              m_MyAlbums.DeleteAllItems();
               m_MyAlbums.InsertItem(0, _T("Self Titled"));
               m_MyAlbums.SetItemText(0,1, _T("2001"));    
          }
     }
}

Your syntax is wrong in the two if statements where you check for "311" and "Adema"

What you need to do is get the text from the combo box for the selected item, and then compare that with the text strings, thus :

if (nSelection != CB_ERR) // Not LB_ERR, although the two are the same thing!
{
   CString strText;
   m_ComboBands.GetLBText(nSelection, strText);

   if (strText == "311")
   {
      // ...
   }
   else if (strText == "Adema")
   {
      // ...
   }
}

Hope this helps
