VarUtils.VarBoolFromStr Variable

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

Pascal
VarBoolFromStr: function(const strIn: WideString; LCID: Integer; dwFlags: Longint; out boolOut: WordBool): HRESULT;
C++
function(const strIn: WideString; LCID: Integer; dwFlags: Longint; out boolOut: WordBool): HRESULT VarBoolFromStr;

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

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

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

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