problem with manifest

[whatazor]

Hi all,
I have an application, that use wx 2.6.3  with an app.rc made in this
way:

#include <wx/msw/wx.rc>
IDI_ICON1 ICON DISCARDABLE "app.ico"

The problem is that when I compile it with vs2008 it crashes with
r6034 error regarding manifest.
I've modified the project for not generating manifest: same error.
I've put #define wxUSE_NO_MANIFEST 1 before the include... I ve the
same run time error.

Where is the error :( ?

bye
w
