The source code in this issue is designed for all versions of Visual Basic.
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)
None unless an error occurs. If an error occurs this routine will raise the error to the calling subroutine.
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
