[PATCH 0/1] MR10823: winex11: Allow user to set WM_CLASS
by Nicholas Little (＠njlittle) May 5, 2026

May 5, 2026

This commit allows the user to optionally set the WM_CLASS by setting an environment variable WINEWMCLASS with the aim of allowing him to ensure desktop environments can correctly identify wine windows, unfortunately the executable filename isn't always sufficient as some programs share a common executable name.

[PATCH v18 0/5] MR10673: oleaut32: Fix Null handling in three-valued logical ops.
by Francis De Brabandere (＠francisdb) May 5, 2026

May 5, 2026

VarAnd only inspected the non-Null operand one way and left V_BOOL/V_I4 uninitialized. VarImp treated VT_UI1 0xFF as VARIANT_TRUE (it isn't) and its VT_CY -1 check compared unscaled .int64 to -1 instead of -10000. props to @jsm174 for this one: https://github.com/vpinball/libwinevbs/commit/7e877fafe34483623ca33d26ab76f… -- v18: vbscript/tests: Add Null handling smoke tests for logical operators. vbscript: Match native UI1 Imp Null behavior. oleaut32: Fix VT_DATE Null handling in VarImp. oleaut32: Fix VT_CY Null handling in VarImp. oleaut32: Fix Null handling in VarAnd. https://gitlab.winehq.org/wine/wine/-/merge_requests/10673

[PATCH v3 0/1] MR10594: Draft: vbscript: Log call stack trace on runtime errors.
by Francis De Brabandere (＠francisdb) May 5, 2026

May 5, 2026

Add WARN-level trace output showing the call chain when a runtime error propagates through nested function calls. This helps diagnose errors in ExecuteGlobal/Execute code where the reported error location has no context about which call chain led to it. ``` Example output for WINEDEBUG=warn+vbscript: error 0x80020012 in L"Broken", line 3 called from L"Wrapper", line 2 called from <global>, line 16 ``` -- v3: vbscript: Log call stack trace on runtime errors. https://gitlab.winehq.org/wine/wine/-/merge_requests/10594

[PATCH v12 0/2] MR10459: vbscript: Implement DateDiff built-in function.
by Francis De Brabandere (＠francisdb) May 5, 2026

May 5, 2026

Implement DateDiff(interval, date1, date2 [, firstdayofweek [, firstweekofyear]]) with support for all interval types: yyyy, q, m, y, d, w, ww, h, n, s. For yyyy/q/m the difference is computed from calendar fields via VarUdateFromDate. For d/y the day number difference is used. For w it is the day difference integer-divided by 7 (not affected by firstdayofweek). For ww it counts week boundary crossings based on firstdayofweek. For h/n/s the dates are converted to the respective unit and truncated before subtracting. Returns VT_I4 (Long). Null date arguments return Null; null interval or null firstdayofweek/firstweekofyear return VBSE_ILLEGAL_NULL_USE. -- v12: Apply 1 suggestion(s) to 1 file(s) https://gitlab.winehq.org/wine/wine/-/merge_requests/10459

[PATCH 0/1] MR10820: vbscript: Return the script class name from TypeName() on a class instance.
by Francis De Brabandere (＠francisdb) May 5, 2026

May 5, 2026

Native VBScript's TypeName() returns the class name (e.g. "EmptyClass") for instances of script-defined classes; wine returned the generic "Object" string. Add a vbdisp_class_name() helper that pulls the name out of the vbdisp_t -> class_desc_t chain when the IDispatch is one of ours, and consult it before the ITypeInfo path in Global_TypeName. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10820

[PATCH v7 0/4] MR10612: gdi32/uniscribe: Fix heap buffer overflow in ScriptStringAnalyse().
by समीरसिंह Sameer Singh (＠ss141309) May 5, 2026

May 5, 2026

Hi, I came across this bug while solving another issue. Steps to reproduce: 1. Open wine notepad 2. Start spamming any character that requires mark_invalid_combinations() in the notepad, such as: َ (0x064e Arabic Fatha) 3. At nearly 41 inserted Fatha, notepad will crash -- v7: riched20: Increase max_glyphs size. gdi32/uniscribe: Perform bounds check in GSUB_apply_MultipleSubst(). gdi32/uniscribe: Resize the buffers if glyph count exceeds limit. gdi32/uniscribe: Perform bounds check in insert_glyph(). https://gitlab.winehq.org/wine/wine/-/merge_requests/10612
