Requirements for this Issue

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

In this Issue

In the last issue we introduced you to the StringToGenericArray routine. This issue introduces the opposite routine called GenericArrayToString. It will take an array of data and store it as a single string delimited with the delimiter of your choice. Some scenarios where this technique would be useful is during data import/export routines, simple flat-file database management and easy storage for arrays.


Public Sub GenericArrayToString(sData As String, vArray As Variant, ByVal sDelimiter 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

We will demonstrate an example of this routine.

    Dim sData As String
    Dim aData() As Long

    ReDim aData(0 to 4)
    aData(0) = 1
    aData(1) = 5
    aData(2) = 33
    aData(3) = 7
    aData(4) = 332
    GenericArrayToString(sData, aData, ",")

The resulting string (sData) will contain be: 1,5,33,7,332
