Windows 8 (7955) Findings in M3 Leak

[NaiveUser]

alright this should be straightforward and I just got this window

from this code

using System;
using Windows.UI.DirectUI;
using Windows.UI.DirectUI.Controls;

namespace SimpleTest
{
	/// <summary>
	/// Class with program entry point.
	/// </summary>
	internal sealed class Program
	{
		/// <summary>
		/// Program entry point.
		/// </summary>
		[STAThread]
		private static void Main(string[] args)
		{
			var app = new Application();
			app.Activated += (_, ae) => {
				var page = new UserControl();
				Application.LoadComponent(page, "MainPage.xaml");
				ae.Content = page;
			};
			app.Run();
		}
	
	}
}

and this loose xaml file

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="400" Height="300">
    <Grid x:Name="LayoutRoot" Background="Aqua">
		<TextBlock>This is an XAML page</TextBlock>
    </Grid>
</UserControl>

So how much of DirectUI is specific to Windows 8? Isn't it the same UI library used by msn messenger etc.?
eg.
visualstudiogallery.msdn.microsoft.com/1B69C9FE-E422-4799-9EB5-6AC7034C52E1

Great work NaiveUser. If you felt inclined, could you show us the loaded DLLs in that process using something like Process Explorer (I'd post a link to it but I'm a new user!). I'd be interested what D3D version is being used and if D2D is being loaded too .

Thanks!

all I can see and read is

of course, I'm grumpy since its midnight here

[NaiveUser]

HAHAH I just realized that I can actually use async/await in my C# code now ! YEAH !
and there is System.Runtime.InteropServices.WindowsRuntime namespace inside mscorlib.
and there is System.Runtime.WindowsRuntime.dll and System.Threading.Tasks.Dataflow.dll, which are new to 4.5.

well I dont think DirectUI.dll is directly related to the 'DirectUI' in DUI70.DLL/DUSER.DLL now, there is no much clue about the connection btween them. I used to think they are related because of the same name, but it turns out not the case. see the discussions in #166 of this thread.

it turns out, no DirectX at all
BUT, I did see some hint inside the exe about D3D9/DWrite/D2D dlls, and GPU Acceleration, shader compiler etc.

also, Spy++ indicates there is only on top window here, no HWND inside.

UPDATE:
if you add this DWORD value "EnableJupiterCachedComposition" = 1
inside registry key HKEY_CURRENT_USER\SOFTWARE\Microsoft\DirectUI\ then D3D10warp.dll/D3D9.dll shows up.
if you add another DWORD value "EnableAcceleratedGraphics" = 1 then D2D1.dll/D3D10_1.dll/D3D10_1core.dll/D3D11.dll/DWrite.dll/DXGI.dll showsup

What about when you call CreateImmersiveWindow - what class is the HWND that creates, any idea? Just wondering if it might offer a clue as to whether this is related to the old DirectUIHWND stuff.

I'll also be interested to see if you can find any kind of references to trident integration in this.. or any HTML DOM references in DirectUI. I'm assuming that Jupiter has a closer integration with HTML than we've heard so far... at least if you were to believe the MS guys giving the demos. Or perhaps the integration is the other way around - that we'll have some proprietary tag in IE10 to include some of this xaml.

the window class name is the second parameter of CreateImmsersiveWindow, I used 'EDIT' in my demo, other apps use their own classes they registered themselves. and I remember I have messed it up with my own WNDCLASSEX, well, maybe I will try that later.

I think the 'Immersive Window' thing is a low-level Win32 window management concept, and its not related to any specific UI toolkit or framework, to you its just a HWND.
