CXTButton,CXTFlatComboBox and ATL

I am trying to dynamically create a control of the CXTButton class in my ATL application with MFC support.I get a CWnd object from m_hWnd by using CWnd::FromHandle(m_hWnd) to get a temporary MFC CWnd pointer and pass it on to Create function as a parent window handler .

It is really works until I set any  style  for button. Ex.:

So I can not see button on its place ( it is turn be invisible ) ,but I can click on the "button".

The same problem I have with CXTFlatComboBox. After 

m_ctlComboHost.DisableFlatLook(true);

part of control looks incorrect. 

Can anybody help me?

Thanks,
