Waiting to thread exit

Hi I am copyying file in a thread, meanwhile I am displaying a disloag with
progress bar, the problem is that message box is displayed before copying is
finished. Can anyone help me ??

CProgressDlg* pDlg = new CProgressDlg();

if ( ! pDlg ) return;

pDlg->Create( IDD_DIALOG1 );

pDlg->ShowWindow( SW_NORMAL );

CCopyThread* pThread = (CCopyThread* ) AfxBeginThread( RUNTIME_CLASS(
CCopyThread ), THREAD_PRIORITY_NORMAL,

0, CREATE_SUSPENDED );

if ( pThread )

{

pThread->pParent = pDlg;

pThread->ResumeThread();

pThread->CopyFile( "C:\\Test.rmvb", "D:\\Test.rmvb" );

}

AfxMessageBox(" Copy finished " );
