CStatic and painting problems : bis

Hi,

I am rewriting a very simple CStatic derived control when I can display
a bitmap that fits the control so I started with the code below :
The problem is I cannot see my text or my bitmap in function I declare
one before the other.
It seems I am mixing some DC but I cannot find where

// CxStatic.cpp : implementation file
