Deactivating and activating dialog window based on CDialogEx class set focus to first dialog item instead of last focused item before dialog lost focus. This will happen only in CDialogEx. Dialogs based on CDialog works fine.

This issue has been fixed in Visual Studio 2012. The fix is to call Default() in OnActivate

void CMyDialogEx::OnActivate(UINT nState, CWnd *pWndOther, BOOL bMinimized)
    __super::OnActivate(nState, pWndOther, bMinimized);

1) Inherite CDialogEx to own class and create one protected member CWnd *m_wndLastFocused;
2) In constructor set m_wndLastFocused(NULL)
2) override OnActivate and place code:
void CMyDialogEx::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized)

    if (nState == WA_INACTIVE )
        m_wndLastFocused = GetFocus();
    else if( m_wndLastFocused && IsWindow(m_wndLastFocused->m_hWnd) )

This will correct this problem.
