Namespace:  XSharp.Core
Assembly:  XSharp.Core (in XSharp.Core.dll) Version: 2.2a
Syntax
 FUNCTION LoWord(
	dwValue AS DWORD
) AS WORD
View Source

Parameters

dwValue
Type: UInt32
The number whose low-order word you want to get.

Return Value

Type: UInt16
Remarks
Related data can be stored in the high-order and low-order words of a variable.  Therefore, instead of creating and returning a 2-element array, it may be more efficient to return a double word whose 2 words contain separate information.  Also, many Windows API functions receive data in a LONGINT argument.  Usually the high-order and low-order words of this argument contain different information about a window and its messages.  LoWord() can be used to extract the low-order word of this argument.
Examples
This example uses LoWord() and HiWord() to determine the coordinates of a pixel.  It assumes that liParam was passed to a Windows callback function:
X#
CRTSetPixel(LoWord(liParam), HiWord(liParam), 0L)
