The source code in this issue is designed for all versions of Visual Basic.
Everyone eventually requires the ability to sort an array of data. Unfortunately this functionality was not built into Visual Basic the way it is built into C. This issue discusses one implementation for sorting an array of data. Of course there are many additional ways to sort data but this routine provides a fairly quick method for sorting any size array. It uses a sort method called the selection sort.
Public Sub SelectionSortText(vArray As Variant, ByVal sOrder As String)
None unless an error occurs. If an error occurs this routine will raise the error to the calling subroutine.
This subroutine shows one example for calling the SelectionSortText function.
Dim saData() As String
' ... dimension array... and load it with data
On Error Resume Next
Call SelectionSortText(saData, "ascending")
If Err Then
MsgBox "Error Sorting Data."
End If

If you are interested in sorting Long numbers instead of strings, just change the following:
You can do similiar conversions to support Single, Double, Currency and Integer. If you have any questions about implementing the numeric sort, let us know.
That concludes this issue of COTW. We hope you find the source code useful in your development.
