 Controls locking up the application in sheet contained within a TabCtrl ( Controls, CDialog and CTabCtrl problems )

Hello all,

  I am having a problem with some controls in a dialog box. Originally I had
assert errors, but I have solved this problems ( I think unless what I have
done is related to my current problem. ) I have an application who's main
window is a dialog box. In this dialog box I have a classed that is derived
from CTabCtrl. There is going to be seven tabs with each tab sheet having
its own class that is inserted into my derived class.

  I want each tab sheet to have it own class since it will be doing some
processing. Right now I am working on one tab sheet. I have create spin
counter using two controls ( CEdit and CSpinButtonCtrl ) using the buddy
declaration found in CSpingButtonCtrl. Initially I knew soemthing was wrong
since I set some values, but they were not showing up when you first went to
the tab sheet. The values I was setting is

  m_NumOfVAZonesCtrl.SetRange( 0, 10 );
  m_NumOfVAZonesCtrl.SetBase( 10 );
  m_NumOfVAZonesCtrl.SetPos( 10 );

  When you go tab sheet it doesn't start at 10, but 0. In additon whenever
you click on any controls ( check box, button spinner control etc.. ) the
applications locks up. I have included some source listing to help out. I
also found by changing the line

m_tabFormPages[5]->Create( IDD_FORM_VA,       this );


m_tabFormPages[5]->Create( IDD_FORM_VA,       NULL );

then selecting a control on the tab sheet doesn't lock up the application,
but it still isn't displaying the values I initialized it to.

  The program class structure goes like this..

    -> CFormTabCtrl ( a derived CTabCtrl that is in main dialog screen,
                          has 7 tab sheets )
          -> CFormVideoAnnouncement ( which is the current tab sheet I am working
                                      on that is contained within CFormTabCtrl )

Does anyone have any idea what is causing this? Thanks. I have included some
source code, but I have tried to only list code that would he helpful and some
code may be excluded from certain methods.
