Requirements for this Issue

The source code in this issue is designed for all versions of Visual Basic.

In this Issue

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)


Return Value

None unless an error occurs. If an error occurs this routine will raise the error to the calling subroutine.

Sample Usage

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

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.
