Hello Wine developers,

I don't know if you guys are interested in this or not, but I figured I'd let you know that Microsoft has now documented one of the undocumented toolbar messages.

include/commctrl.h (Wine)

#define TB_UNKWN45D             (WM_USER + 93)

include\um\commctrl.h (Windows)

#define TB_SETBOUNDINGSIZE      (WM_USER + 93)

TB_SETBOUNDINGSIZE message

<< Sets the bounding size for a multi-column toolbar control. >>

That would mean you could also make the corresponding changes to this code as well:

dlls/comctl32/toolbar.c

case TB_UNKWN45D:

    return TOOLBAR_Unkwn45D(hwnd, wParam, lParam);

/* UNDOCUMENTED MESSAGE: This appears to set some kind of size. Perhaps it

 * is the maximum size of the toolbar? */

static LRESULT TOOLBAR_Unkwn45D(HWND hwnd, WPARAM wParam, LPARAM lParam)

Anyway, just figured I'd share that with you guys.

Cheers,

  Alan Feldman
