VarBstrFromBool is used to specify the function that makes the conversion from a boolean value to a WideString.

Pascal
VarBstrFromBool: function(boolIn: WordBool; LCID: Integer; dwFlags: Longint; out bstrOut: WideString): HRESULT;
C++
function(boolIn: WordBool; LCID: Integer; dwFlags: Longint; out bstrOut: WideString): HRESULT VarBstrFromBool;

Description

Use VarBstrFromBool to specify the function that makes the conversion from the boolean value given through boolIn to the WideString stored in bstrOut. The LCID parameter is a locale identifier and dwFlags specifies the flags used in the conversion.  

The function stored in VarBstrFromBool returns the result of the conversion operation, which can be one of the following.

Value 
Meaning 
VAR_OK 
The conversion was successful. 
VAR_BADVARTYPE 
The variant type of the input parameter is not valid. 
VAR_OVERFLOW 
The data stored in the output parameter does not fit in the destination type. 
VAR_TYPEMISMATCH 
The argument cannot be cast to the specified type. 
VAR_INVALIDARG 
Either one of the arguments is invalid. 
VAR_OUTOFMEMORY 
There is not enough memory to complete the conversion. 

To make the inverse conversion, from a WideString to a boolean value, use the function referenced by VarBoolFromStr.
