The app is doing something similar but I don't think it is the same
problem.
SendMessage(hwndTB, TB_SETSTYLE, 0, SendMessage(hwndTB, TB_GETSTYLE, 0,
0) & ~ TBSTYLE_LIST);
But this is not done in the WM_CREATE message.
After investigation, the toolbar is not invisible, it has a size of
(0,26) which of course makes it invisible. The problem was that the
style return was the style of a separator button and so the style of the
toolbar was totally false.
I will try to fix both problems.
