[DX9,Vista] lost due to display uniqueness change

    [DX9,Vista] lost due to display uniqueness change

    So, I am trying to get back to using DirectX with C++ from C# with XNA.

    I am following the tutorials on Druinksoft and I am trying to implement the fullscreen swap in tutorial 3.

    Using the code from the website, when I try to go to fullscreen, it swaps resolution and then just sits there. No spinning triangle, just nothing. When I try to exit it, it won't exit. After using task manager to end the process, a error window pops up on the screen saying something about a heap overflow or a user pressed F12 (which I didnt). After fiddling around trying to get my resolution back to normal, I saw this error in the output window..

    "Lost Device Due to Display Uniqueness Change" from the DirectX Debug spew.

    After searching around a bit, I come across this thread and it says something about having to use Vista's DX9 extensions. It also says, I will lose compatibility with XP if I use them, which I don't want. It does suggest checking WINVER before creating the device as an answer.

    Basically, that thread is a bit dated and was wondering if there is a way around this issue. I would also like to keep using the debug runtime has they are handy. Should I just not use fullscreen until I am done with my project?

    Any help/advice would be great! Thanks!

    P.S.  Yeah, I posted this on GameDev, but if I find a response on either Gamedev or here, I will post the answer on the opposite site.

    Well, I have decided I will just destroy the device/object and create new ones.  Though I haven't tested it yet (at school now), it seems to be the simplest way to do things since I need to reset it anyways.
