Win8 M3 (7989) findings relevant to Managed .net & WPF/SL developers

and also DWriteCreateFactory/D3D10CreateDevice1/DXVA2CreateDirect3DDeviceManager9 etc.

 

it looks like ms have done a big-merge from Silverlight 5 branch, between 7955(110228) and 7989(110421), note Silverlight 5 beta is released on 2011/04/11 (MIX11).

There is a string inside 7955 DirectUI.dll says "APP_EARLIER_THAN_SL4.0", which is also seen inside agcore.dll in Silverlight 4, and in 7989 there is one more string says "APP_EARLIER_THAN_SL5.0" inside DirectUI.dll, which can be found inside agcore.dll in Silverlight 5 Beta, and actually HwndHost and HwndBrush are also there.

 

CreateDrawingSurfaceFactory is used by the PDF reader. Obviously it cannot draw a pdf document by using DirectUI directly so it uses D2D do draw on a surface/element created by DirectUI.

OsMinVersion = 6.1

this could mean that these Jupiter App will work on Windows 7.
Since apparently they can run in immersive mode and desktop mode
an update to Win7 ( sp2 ?) could add support for jupiter and more importantly
to the new AppStore.

 

Simple, that's a WinRT class, it gets 'activated' as an out of process object.

 

oh really ? where are they ?
as far as I can see, there are some WinRT 'Activatable Classes' called "Windows.glcnd" and "Microsoft.Windows.MoCam" but I can't find 'glcnd.class' or 'webcam.class'.

and if these are WinRT classes, who registered them and when ? if its automatically registered, why you need to specify it in the manifest ?
and also, why you still need to specify the 'executable' file name ? really confused.

update: well, inside HKEY_CURRENT_USER\Software\Classes\ActivatableClasses\Package\windows.glcnd.package_1.0.0.0_neutral_en-us_cw5n1h2txyewy\ActivatableClassId\Windows.glcnd\CustomAttributes
there is a value AppObject.EntryPoint=glcnd.class but I think this 'attribute' is actually copied from the manifest. the chicken and the egg ....

 

Good questions. I think I confused the Id of the Application (which is Windows.glcnd, same as the WinRT class name) with the entry point which is "glcnd.class".

Weird, glcnd.class is no where to be found. Not even the .class suffix.

There's a C++ class named AppFactory which can probably create the application object but since that entry point name is not in the executable... hmm...

 

Mr. SilverlightWPF, it look like you are a graphics expert, do you know what are these xml files inside d2d1.dll.mui as resources ?

Comment from a d2d shader:

Code:

// Shader fragments shared between D2D and DImage code

DImage? Is that some sort of spelling mistake or does it mean "DirectImage"?
