Sorting Macros

Include file: AfxNova/AfxSort.inc.

Note: Before including this file, add

#define _WIN32_WINNT &h0602

Name	Description
AfxSortNumericArray	Sorts one-dimensional numeric arrays of any type.
AfxSortStringArray	Sorts one-dimensional string arrays of any type.

AppendElementToArray

Appends a new element to a dynamic one-dimensional array.

#macro AppendElementToArray(rg, elem)

Parameter	Description
rg	The array.
elem	The element to append.

Remarks

The array and the element to append can be of any type, but they have to be of the same type between them.

If the array has a fixed length, GetLastError will return an E_ACCESSDENIED error.

Usage example

#define XSTRING DWSTRING ' // or STRING, BSTRING, etc.
DIM rg(ANY) AS XSTRING
DIM xStr AS XSTRING = "String - "
FOR i AS LONG = 1 TO 10
   AppendElementToArray(rg, xStr & WSTR(i))
NEXT
' Display the array
FOR i AS LONG = LBOUND(rg) TO UBOUND(rg)
   print rg(i)
NEXT

AppendArrayToArray

Appends a one-dimensional array to another dynamic one-dimensional array.

#macro AppendArrayToArray(rg, rg2)

Parameter	Description
rg	The array.
rg2	The array to append.

Remarks

The array and the array to append can be of any type, but they have to be of the same type between them.

If the array has a fixed length, GetLastError will return an E_ACCESSDENIED error.

Usage examples

#define XSTRING DWSTRING ' // or STRING, BSTRING, etc.
DIM rg(ANY) AS XSTRING
DIM rg2(ANY) AS XSTRING
DIM xStr AS XSTRING = "String - "
' // Fill the array
FOR i AS LONG = 1 TO 10
   AppendElementToArray(rg, xStr & WSTR(i))
NEXT
' Fill the array to append
xStr = "String 2 - "
FOR i AS LONG = 1 TO 5
   AppendElementToArray(rg2, xStr & WSTR(i))
NEXT
' // Append the array to the first array
AppendArrayToArray(rg, rg2)
' // Display the array
FOR i AS LONG = LBOUND(rg) TO UBOUND(rg)
   print rg(i)
NEXT

Can also be used with numbers:

DIM rg(ANY) AS LONG
DIM rg2(ANY) AS LONG
' // Fill the array
DIM nLong AS LONG = 1
FOR i AS LONG = 1 TO 10
   AppendElementToArray(rg, nLong)
   nLong += 1
NEXT
' Fill the array to insert
nLong = 12345
FOR i AS LONG = 1 TO 5
   AppendElementToArray(rg2, nLong)
   nLong += 1
NEXT
AppendArrayToArray(rg, rg2)
' // Display the array
FOR i AS LONG = LBOUND(rg) TO UBOUND(rg)
   print rg(i)
NEXT

InsertElementIntoArray

Inserts a new element before the specified position into a dynamic one-dimensional array.

#macro InsertElementIntoArray(rg, pos, elem)

Parameter	Description
