Hi,
I am doing the DirectX programming course part 2 with the Game Institute. I have had many problems with finding the solutions to these errors, but this one is nowhere to be found. i have gone over the code and it matches the course project but still, when I run my game engine it runs aground instantly. It brings up an error saying "Device creation failed. The application will exit". This error message occurs when the "CreateDisplay" function shown below fails.
Any help will be appreciated. Thanks in advance
