Here is some code, I cut some some parts but all MFC stuff is there:

//Called when clicking Reconnect button
void myDlg::OnBnClickedButtonReconnect()
{
  StartReconnectStatusThread();
  if(ConnectToLastUsedDevice())
  {
    StopReconnectStatusThread();
    ConnectionCompleted();
  }
}

//Called when clicking start wizard button, the pairing guide will
show 3 other modal dialogs and finally return TRUE or FALSE
void myDlg::OnBnClickedButtonStartWizard()
{
  this->ShowWindow(SW_SHOWMINIMIZED);
  if(RunPairingGuide())
  {
    ConnectionCompleted();
  }
  else
  {
    ConnectionFailed();
}

//This is a thread just showing a "splash" screen that we are trying
to reconnect. Upon success this is terminated
void myDlg::ShowReconnectionStatus()
{
  //Display the reconnect status dlg
  ReconStatusDlg myReconStatusDlg;
  myReconStatusDlg.Create(IDD_RECON_STATUS);
  DWORD res = WaitForSingleObject(h_WaitForReconnect,10000);
  myReconStatusDlg.OnBnClickedCancel(); //remove the status Dlg
}

//This is the function called both when reconnecting and running the
wizard. Ok result when wizard has run failing after reconnect.
void myDlg::ConnectionCompleted()
{
  ToggleApplicationSelectionInfo(SW_SHOW); //show or hide some
controls

  PrintStaticMessage(IDC_STATIC_WELCOME_MSG, "Welcome", HEADLINE);

  PrintStaticMessage(IDC_STATIC_HP_RECONNECT_INFO, message,
STANDARD_FONT);
  CButton* myButton = (CButton*)GetDlgItem(IDC_BUTTON_START_WIZARD);
  myButton->EnableWindow(false);
  myButton = (CButton*)GetDlgItem(IDC_BUTTON_RECONNECT);
  myButton->EnableWindow(false);
  myButton = (CButton*)GetDlgItem(IDC_BUTTON_ADD);
  myButton->EnableWindow(false);

  CStatic* myStatic = (CStatic*)GetDlgItem(IDC_STATIC_SELECT_APP);
  myStatic->EnableWindow(false);

  CListBox* myLB = (CListBox*)GetDlgItem(IDC_APPNAME_LISTBOX);
  myLB->EnableWindow(false);

  this->ShowWindow(SW_MINIMIZE);
  ::FlashWindow(GetHwnd(),true); //Flash once to show user where the
window went
}

//Helper function will take SW_HIDE or SW_SHOW as inparameter but
should only affect specific controls
void myDlg::ToggleApplicationSelectionInfo(int SW_CODE)
{
    CWnd* myWnd;
    myWnd = (CWnd*)GetDlgItem(IDC_APPNAME_LISTBOX);
    myWnd->ShowWindow(SW_CODE);
    myWnd = (CWnd*)GetDlgItem(IDC_STATIC_SELECT_APP);
    myWnd->ShowWindow(SW_CODE);
    myWnd = (CWnd*)GetDlgItem(IDC_BUTTON_ADD);
    myWnd->ShowWindow(SW_CODE);
}
