Direct2D - What am I doing wrong?

Hi, I'm a total noob so the answer may be very simple. I've attached a zip with a header and cpp file and just want to know what I'm doing wrong.

I'm just trying to simply render "white" with Direct2D onto a GDI DC.

It's compiles fine but crashes instantly.

Thanks in advance.

Don't worry, I fixed it. I just made my factory and render target stuff etc. in the global scope instead of being in a class. Seems fine, but it won't cause any issues later on will it?
