From: Francis De Brabandere <francisdb@gmail.com> Native VBScript raises error 458 (VBSE_INVALID_TYPELIB_VARIABLE) when an expression involves a Variant whose type is one of VT_UI2/VT_UI4/ VT_UI8/VT_UINT, on both 32-bit and 64-bit. Add a script-level type gate at the entry of var_cmp so BSTR-vs-{UI2,UI4,UI8,UINT} comparisons match. --- dlls/vbscript/interp.c | 16 ++++++++++++++-- dlls/vbscript/tests/lang.vbs | 10 +++++----- 2 files changed, 19 insertions(+), 7 deletions(-) diff --git a/dlls/vbscript/interp.c b/dlls/vbscript/interp.c index b4d82bbc7f6..7ff3baecce8 100644 --- a/dlls/vbscript/interp.c +++ b/dlls/vbscript/interp.c @@ -2111,8 +2111,17 @@ static inline BOOL is_numeric_vt(VARTYPE vt) { return vt == VT_I2 || vt == VT_I4 || vt == VT_R4 || vt == VT_R8 || vt == VT_CY || vt == VT_DATE || vt == VT_UI1 || vt == VT_DECIMAL - || vt == VT_I1 || vt == VT_I8 || vt == VT_UI2 || vt == VT_UI4 - || vt == VT_UI8 || vt == VT_INT || vt == VT_UINT; + || vt == VT_I1; +} + +/* Native VBScript rejects these Automation types with error 458 + * (VBSE_INVALID_TYPELIB_VARIABLE) when they appear in script expressions, + * on both 32-bit and 64-bit.
