Getting the window up and running with directx initialized

I've been trying to find a way to make the process of getting a window with direct3d going a bit more object oriented. All of the examples you tend to see don't really do that. So I've written a class that does this and hopefully allows me to reuse this code for other projects. It's my first time so there's probably going to be some changes along the way as I get more familiar with how I want to set it all up.

Here's a screenshot of my window with directx initialized. So far I just told the render frame function to draw a black background. As I flesh out my particle system class this image will get a lot more interesting.
