[PATCH v2 0/1] MR10424: services: Cancel overlapped IO after timeout.
by Yuxuan Shui (＠yshui) March 26, 2026

March 26, 2026

Though WaitForSingleObject timed out, the IO operation is still running in the background. After the function process_send_command returns, the OVERLAPPED object referenced by this IO operation becomes invalid. Later, when this IO finally completes, server_select will use invalid stack memory. -- v2: services: Cancel overlapped IO after timeout. https://gitlab.winehq.org/wine/wine/-/merge_requests/10424

[PATCH 0/1] MR10462: vbscript: Return type mismatch when calling non-dispatch variable as statement.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 2026

When a non-dispatch variable (integer, string, empty, etc.) is used as a statement with no arguments, return VBSE_TYPE_MISMATCH (error 13) instead of E_NOTIMPL. This matches native Windows VBScript behavior. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10462

[PATCH v2 0/1] MR10450: vbscript: Return correct error for array dimension mismatch and NULL array access.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 2026

Return VBSE_OUT_OF_BOUNDS (error 9, "Subscript out of range") instead of E_FAIL for array dimension mismatch in array_access() and for NULL SAFEARRAY access in variant_call() and do_mcall(), matching native Windows behavior. -- v2: vbscript: Return correct error for array dimension mismatch and NULL array access. https://gitlab.winehq.org/wine/wine/-/merge_requests/10450

[PATCH 0/1] MR10455: vbscript: Return "Object required" error (424) instead of E_FAIL/E_NOTIMPL.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 2026

Fix several interpreter code paths that returned wrong error codes when an object was expected but not provided: - stack_pop_disp: E_FAIL -> 424 for non-dispatch types. - do_mcall: E_FAIL -> 424 when calling a member on Nothing. - interp_assign_member: E_FAIL -> 424 for Nothing.Prop = value. - interp_set_member: E_FAIL -> 424 for Set Nothing.Child = obj. - interp_is: E_NOTIMPL -> 424 for non-object Is operands. Also add OP_with opcode to validate the With expression is a dispatch object at entry time, matching Windows behavior where With on non-object types (integers, strings, Empty, Null, booleans) raises error 424 immediately, while With Nothing succeeds. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10455

[PATCH v3 0/1] MR10461: vbscript: Implement IDispatch::GetTypeInfo for class instances.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 2026

Implement GetTypeInfo on vbdisp_t (VBScript class instances) by returning an ITypeInfo that reports the class name via GetDocumentation(MEMBERID_NIL) and exposes public methods and properties via GetFuncDesc, GetVarDesc, GetNames, GetIDsOfNames, and GetTypeAttr. This makes TypeName() return the actual class name (e.g. "MyClass") instead of falling back to "Object". This is partially based on previous work by @jsm174 at https://github.com/jsm174/libwinevbs/blob/fbc4d2a17a2da8196d50805f7ae289406… -- v3: vbscript: Implement IDispatch::GetTypeInfo for class instances. https://gitlab.winehq.org/wine/wine/-/merge_requests/10461

March 26, 2026

Implement GetTypeInfo on vbdisp_t (VBScript class instances) by returning a lightweight ITypeInfo that reports the class name via GetDocumentation(MEMBERID_NIL). This makes TypeName() return the actual class name (e.g. "MyClass") instead of falling back to "Object".

[PATCH v9 0/1] MR10444: vbscript: Implement GetRef.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 2026

GetRef returns a callable IDispatch object that wraps a script function or sub, allowing it to be assigned to a variable and invoked later. The returned object calls exec_script on DISPID_VALUE invocation.

[PATCH 0/1] MR10459: vbscript: Implement DateDiff built-in function.
by Francis De Brabandere (＠francisdb) March 26, 2026

March 26, 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. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10459
