NAME
VarBoolFromStr (OLEAUT32.125)SYNOPSIS
HRESULT VarBoolFromStr(
OLECHAR* strIn,
LCID lcid,
ULONG dwFlags,
VARIANT_BOOL* pBoolOut
)
DESCRIPTION
Convert a VT_BSTR to a VT_BOOL.
PARAMS
strIn [In] Source.lcid [In] LCID for the conversion.
dwFlags [In] Flags controlling the conversion (VAR_ flags from "oleauto.h").
pBoolOut [Out] Destination.
RETURNS
Success: S_OK.
Failure: E_INVALIDARG, if pBoolOut is invalid. DISP_E_TYPEMISMATCH, if the type cannot be converted.
NOTES
- strIn will be recognised if it contains "#TRUE#" or "#FALSE#". Additionally, it may contain (in any case mapping) the text "TRUE" or "FALSE".
- If dwFlags includes VAR_LOCALBOOL, then the text may also match the localised text of "TRUE" or "FALSE" in the language specified by lcid.
- If none of these matches occur, the string is treated as a numeric string and the boolean pBoolOut will be set according to whether the number is zero or not. The dwFlags parameter is passed to VarR8FromStr(3w) for this conversion.
- If the text is not numeric and does not match any of the above, then DISP_E_TYPEMISMATCH is returned.
IMPLEMENTATION
Defined in "oleauto.h".
Implemented in "dlls/oleaut32/vartype.c".
