[PATCH v7 0/6] MR8831: vccorlib140: Implement support for boxed values (aka IPropertyValue)
by Vibhav Pant (＠vibhavp) Aug. 26, 2025

Aug. 26, 2025

C++/CX exposes `IPropertyValue` through `Platform::Details::CreateValue`, which returns a `Platform::Object` (which just seems to be a `IPropertyValue` object + C++ RTTI) containing the boxed value. Apps don't seem to call `CreateValue` directly with a typecode. The code for boxing values gets generated when a value type gets assigned to a `Platform::Object` variable, as documented [here.](https://learn.microsoft.com/en-us/cpp/extensions/boxing-cpp-componen… The generated code will: 1. Call `__abi_make_type_id` with a `struct __abi_type_descriptor *` value, which is just a typecode + string pair. This returns a `Platform::Type` object. 2. Call `Platform::Type::GetTypeCode` on the returned `Platform::Type` object to get back the typecode. 3. Call `Platform::Details::CreateValue` with the typecode and a pointer to the actual value that needs to be boxed. Apart from the usual WinRT methods, `Platform::Type` obejcts also impement the `IEquatable` and `IPrintable` interfaces. I don't know what their vtables look like, though. The `Platform::Type` and `Platform::Object` classes also have associated RTTI (can be demonstrated by calling `__RTtypeid`), which we'll also need to emit at some point in the future. -- v7: vccorlib140: Use the correct symbol name for InitControlBlock on i386 and arm. vccorlib140: Implement Platform::Details::CreateValue. vccorlib140: Add stub for Platform::Details::CreateValue. https://gitlab.winehq.org/wine/wine/-/merge_requests/8831

@rbernon do you know if winelib is expected to produce windowing bugs for .so files converted from DLL files vs running those DLL files through Wine runtime? yabridge uses winelib to produce VST.so files. Might winelib be missing components when exporting to .so files that otherwise exist for Wine runtime that fixes the bugs? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6569#note_113850

Followup to: 3e67471d02 Looks like this sould be a >= as it affects just d3dx10_40, at least with it the test succeeds on testbot.

[PATCH v2 0/1] MR8669: Draft: Map low level hooks coordinates correctly in win32u
by Santino Mazza (＠tati) Aug. 26, 2025

Aug. 26, 2025

Coordinates from mouse low level hook messages are not mapped the same way than WM_MOUSEMOVE or GetCursorPos. This causes problems on programs that make use of both values to calculate mouse movement, like the wine DirectInput implementation. I'm marking this as a draft since I was not able to find a way to write a test for this. I'm able to easily reproduce it on Proton, because it creates a scaled full screen window, on Wine this doesn't happen so the coordinates are not required to be mapped to a scaled window. Edit: I didn't realize that modesetting emulation was an experimental option! So, I was able to reproduce the bug by enabling it. -- v2: win32u: Map raw coordinates to virtual screen in low-level hooks. https://gitlab.winehq.org/wine/wine/-/merge_requests/8669

You should stop updating your MR every day. Not only is it a waste of CI resources, but it makes it look like it's not ready since it keeps being updated. Also you don't need additional forks, you can create a MR from a different branch in the same fork. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8573#note_113830

Latest updates: https://bugs.winehq.org/show_bug.cgi?id=58552#c43 Carla offers experimental features supporting VST DLL direct usage via Wine similar to how Steam on Linux handles running Windows games. Carla direct VST DLL usage works without the GUI offsets. Carla VST.so converted by yabridge from VST DLLs have GUI offset bugs. Thus it seems yabridge may be handling windowing behavior better left to Wine if possible. Maybe whatever Wine internal windowing component that resolves the GUI offsets for direct DLL usage can be integrated to VST.so files so they may still be used without any other Wine runtime dependencies? These latest tests help further clarify where the underlying faults may lie regarding bug reports against this merge. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6569#note_113829
