/**
		Get the current worksheet/workbook sheet selection as a list of non-contiguous
		ranges and populate the specified Dialog Builder list box with the list. The list
		box name and property must be specified but the function enumerates as needed. This
		function can be used with Dialog Builder list boxes, comboxes, and list controls.
	Example:
		string strMsg;
		// Populate Data Range list box, type out error if problem
		if( PopulateListBoxWithNonContiguousSelection( "StatisticsOn!Tab.Operation.DataLBX" ) )
		{
			strMsg = SO_WKS_DATA_SEL_ERROR_MSG;     // Output error message and return
			strMsg.Write( WRITE_MESSAGE_BOX );
			return FALSE;
		}
	Parameters:
		strListBoxName=Input name of Dialog Builder list box, combox, or list control
		strPropertyName=Input name of Dialog Builder property to set like ".V" or .V2_, default is ".V"
		bAppend=Input option to append new selected ranges in list box (TRUE) or to reset list box and
			populate starting in first row (default FALSE)
		bSelectAll=Input option to select entire worksheet/workbook sheet if there is no selection (TRUE)
			or to return a no selection warning code if there is no selection (default FALSE)
	Return:
		Returns DLG_UTILS_NO_ERROR on success and a DLG_UTILS warning or error code on failure.

		Get the current worksheet/workbook sheet selection range and populate the specified

		Search a windows folder adding any files that match a specified file filter to a Dialog Builder
		list box. Options specify whether or not subfolders are to be recursively searched and whether
		or not the files are to be appended to or are to replace existing files in the list box. The list
		box name and property must be specified but the function enumerates as needed. This function can
		be used with Dialog Builder list boxes, comboxes, and list controls.
	Example:
		string strPath = GetAppPath() + "Filters\";

	Parameters:
		strListBoxName=Input name of Dialog Builder list box, combox, or list control
		strPropertyName=Input name of Dialog Builder property to set like ".V" or .V2_, default is ".V"
		bAppend=Input option to append new selected ranges in list box (TRUE) or to reset list box and
			populate starting in first row (default FALSE)
		strPath=Input path to start searching, default "" is path to Origin ini file  
		strFileFilter=Input file filter which may include DOS wild card characters, default is "*.*"
		bRecursive=Input option to recursively search subfolders, default is FALSE
		wDisplayOptions=Input bitwise flag specifying display options, default value DLG_UTILS_FILE_WITH_PATH
			displays path, filename and filetype, DLG_UTILS_FILE_NO_PATH displays filename and filetype without
			path, DLG_UTILS_FILE_NO_EXT displays path and filename with out filetype extension, and
			DLG_UTILS_FILE_NO_PATH | DLG_UTILS_FILE_NO_EXT displays file name without path or filetype extension
	Return:
		Returns DLG_UTILS_NO_ERROR on success and a DLG_UTILS warning or error code on failure.
