Compile error help

[Flomo Togba Kwele]

I wrote the following class:

Public Class CassPrintCompar er2
Implements IComparer(Of ICASSPrint)

Private _sortDescending As Boolean = False

'pass true to the constructor to sort descending
Public Sub New(ByVal descending As Boolean)

_sortDescending = descending

End Sub

Public Function Compare(ByVal x As MailHouse2.Data Access.ICASSPri nt, ByVal y
As MailHouse2.Data Access.ICASSPri nt) As Integer

If (_sortDescendin g) Then
Return y.SerialNo.Comp areTo(x.SerialN o)
Else
Return x.SerialNo.Comp areTo(y.SerialN o)
End If

End Function

End Class

I get the following syntax error which I cannot figure out:

Error - Class 'CassPrintCompa rer2' must implement 'Function Compare(x As
MailHouse2.Data Access.ICASSPri nt, y As MailHouse2.Data Access.ICASSPri nt) As
Integer' for interface 'System.Collect ions.Generic.IC omparer(Of ICASSPrint)'.

I just cannot see what I've done wrong. The IDE puts the squiggly error line
under IComparer(Of ICASSPrint).

Thanks, Flomo

Flomo,

I think the syntax is:

Public Function Compare(ByVal x As MailHouse2.Data Access.ICASSPri nt, ByVal y
As MailHouse2.Data Access.ICASSPri nt) As Integer Implements IComparer(Of
ICASSPrint).Com pare

Thanks, Kerry, I'm still a beginner.
