Implements the MinDate and MaxDate properties.

Pascal
function MsgSetRange(Flags: Integer; SysTime: PSystemTime): Boolean; virtual; abstract;
C++
virtual __fastcall Boolean MsgSetRange(int Flags, PSystemTime SysTime) = 0;
Description

MsgSetRange implements the MinDate and MaxDate properties by sending a message to the calendar window handle. MsgSetRange is an abstract method, and must be overridden in descendant objects to send the appropriate message. 

The Flags parameter indicates what type of information is included in the SysTime array. It includes the GDTR_MIN flag if a minimum date is supplied and GDTR_MAX if a maximum date is supplied. 

The SysTime parameter is a two-element array containing the minimum date as the first element and the maximum date as the second element. These values can be obtained from the MinDate and MaxDate properties by calling DateTimeToSystemTime. 

MsgSetRange returns true if the range is set by the method.
