[SOLVED] Error on Visual basic studio

Hello,
I use Visual basic studio and when I tried to run, there is an error.

The error is ; The project ‘libbox2d’ cannot be started directly.

Include the header file of box2d.
ex: #include <Box2D/Box2D.h>

Or because you have put the project as default starting

Yes, I launched with ‘libcocos2d’ as project startup.

Now I launch with “PROJECT NAME” and it’s ok

Thx.
