Fullscreen Managed DirectX

Hi everyone,

I'm having a problem with fullscreen mode in my managed directX application. I was wondering if someone could help me...

When my application is in fullscreen mode, I see artificats and other visual glitches such as pieces of the taskbar at the bottom of the screen. And although the screen is blue, I can still interact with the taskbar. (ie. I click the lower left hand corner and another glitch shows the start menu open momentarily). What could be causing this and how do I fix it

I'm having another problem too. Well, it's not really a problem so much as an annoyance. I've started making a game framework for my future directX games and it's been going great so far. I'm using Visual Studio C# 2005 Express, and I started my coding in an empty project. For some reason each time I start my app I get a console window as well as a normal window appearing. How do I make it disappear All I want is the normal window :P

Thanks in advance,

- Ryan

I took this from my own code.It sets up Direct3D in 2d for fullscreen, but it's generally the same for 3d as well. Hope it helps.

        /// <summary>
        /// Initialize graphics here.
        /// </summary>
        public void InitializeGraphics()
        {
            // Set presentation paramters
            D3D.PresentParameters presentParams = new D3D.PresentParameters();
            presentParams.SwapEffect = D3D.SwapEffect.Discard;

            // Get the ordinal Direct3D adapter
            int adapterOrdinal = D3D.Manager.Adapters.Default.Adapter;

            // Get device caps
            D3D.Caps caps = D3D.Manager.GetDeviceCaps(adapterOrdinal, D3D.DeviceType.Hardware);

            // Set creation flags - start with a default of software vertex processing.
            D3D.CreateFlags flags = D3D.CreateFlags.SoftwareVertexProcessing;

            // Is there support for hardware vertex processing If so, replace
            // software vertex processing.
            if (caps.DeviceCaps.SupportsHardwareTransformAndLight)
                flags = D3D.CreateFlags.HardwareVertexProcessing;

            // Does the device support a pure device
            if (caps.DeviceCaps.SupportsPureDevice)
                flags |= D3D.CreateFlags.PureDevice;

            // Get current display mode
            D3D.Format current = D3D.Manager.Adapters[0].CurrentDisplayMode.Format;

            // See if full screen can be obtained.
            if (D3D.Manager.CheckDeviceType(adapterOrdinal, D3D.DeviceType.Hardware, current,
                current, false))
            {
                // Full Screen can be used.
                presentParams.Windowed = false;
                presentParams.BackBufferCount = 1;
                presentParams.BackBufferWidth = WIDTH;
                presentParams.BackBufferHeight = HEIGHT;
                presentParams.BackBufferFormat = current;
            }
            else
            {
                // Open as a windowed application.
                presentParams.Windowed = true;
            }

            // Create the Direct3D device.
            device = new D3D.Device(adapterOrdinal, D3D.DeviceType.Hardware, this, flags,
                presentParams);
        }

Yay! I think I may have fixed it. I've added the following lines of code:

// Gets rid of the window's border (and the flickering that happens when you mouse over it).
theWindow.FormBorderStyle = FormBorderStyle.None;

// This seems to have stopped the flickering of the task bar.
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.Opaque, true);

Can anyone tell me what the last line of code is doing and why it has stopped the flickering Although the flickering does come back if the user presses Ctl-Alt-Del while it is running... but I suppose that can easily be solved by minimizing the application.

Thanks,

The using control styles.opaque sets form to be painted that way as it is in fact a control.

By default in designer forms and controls are transparent capable with a transparent key (if you look towards the bottom of a form properties in designer).

By changing the transparency to 0% you make the form opaque as your code does. (hiding glitches while onpaint happens)
