I'm upgrading an vb6 application to vb.net. And there were a host of Build Errrors. One of them is on the use of a callback function. I'm getting the following error "Address cannot be converted to integer because integer is not a delegate integer". The code that's being referenced is:

iRC = EntEnumN(ghSelect, HYP_ID_ACCTLISTENTRY, sigAcctList, AddressOf EnumAcctListEntriesCB, lParam, 0)

The callback function is:

Public Function EnumAcctListEntriesCB(ByVal hSelect As Integer, ByVal sigRecd As Integer, ByVal sigKey As Integer, ByVal lParam As Integer, ByRef apis As APISTRUCT) As Short

If I change the callback function to:
Public Delegate Function EnumAcctListEntriesCB(ByVal hSelect As Integer, ByVal sigRecd As Integer, ByVal sigKey As Integer, ByVal lParam As Integer, ByRef apis As APISTRUCT) As Short , then I get additional errors "Declared Expected" for the un


Public Delegate Function EnumAcctListEntriesCB(ByVal hSelect As Integer, ByVal sigRecd As Integer, ByVal sigKey As Integer, ByVal lParam As Integer, ByRef apis As APISTRUCT) As Short

Dim sListEntry As String
Dim iRC As Integer
Dim sigEntry As Integer

sListEntry = Space(HYP_SIZEFULLACCT + 1)

If lParam = 1 Then 'Dynamic List
iRC = EntQueryStrN(ghSelect, HYP_ID_ACCOUNTS, HYP_ACCT_FULLNAME, sigKey, HYP_NONE, Len(sListEntry), sListEntry, 0)
sListEntry = CB(sListEntry)
Form1.DefInstance.List2.Items.Add(sListEntry)
' frmAcctEntList.lstEntries.AddItem sListEntry$
Else 'Fixed List
' trick: sigKey and sigRecd are flip-flopped
' Query for entry_sig, then query ACCOUNTS using entry_sig
iRC = EntQueryN(ghSelect, HYP_ID_ACCTLISTENTRY, HYP_ENTRY_SIG, sigKey, sigRecd, Len(sigEntry), sigEntry, 0)
iRC = EntQueryStrN(ghSelect, HYP_ID_ACCOUNTS, HYP_NAME, sigEntry, HYP_NONE, Len(sListEntry), sListEntry, 0)
sListEntry = CB(sListEntry)
Form1.DefInstance.List2.Items.Add(sListEntry)
frmData.DefInstance.List1.Items.Add(sListEntry)
End If

EnumAcctListEntriesCB = 0

End Function


Any help appreciated.
