Objet : ActiveX control in python vs ActiveX control in vb 6 (piece of code)

Hello, 
 I am trying to migrate from vb 6 to python. 
 
I have a very usefull AX control. It can be : 
     -just a bitmap 
     -an active picture where you can plot data and put cursors 
     -a data explorer 
 
Those 3 behavior are driven by one property in visual studio when you 
 insert the AX control in a form: the property ModuleName: 
    -'default' for bitmap 
    -'Picture' for a picture 
 
I try to insert this AX control in a wxpython based application (I 
 used one of the example delivered with wx) but when I try to change 
 the property to get an active picture it does not work and display me 
 the default bitmap :( 
 
Here is the pice of code

I suspect that the activex control is bugged .... but how to know that 
 since it is working perfectly under visual studio vb 6 but not with 
 python ?:( 
 
please help me !
