Not very good at explaining things - but we got there in the end. As a side note: you could organise the enum values better if it's not too late. Something like:

<Flags()> _
Public Enum E_SecurityCodes
    DMS_None = 0
    DMS_Accounting_AR = 1
    DMS_Accounting_AP = 2
    DMS_Accounting_PR = 4
    DMS_Accounting_All = 7
    'Or, if you don't trust your maths, you can use
    'DMS_Accounting_All = DMS_Accounting_AR Or DMS_Accounting_AP Or DMS_Accounting_PR
    DMS_HR_Employee = 8
    DMS_HR_Caregiver = 16
    DMS_HR_All = 24
    DMS_Client = 32
    DMS_All = 63
End Enum

This way you use up a lot less ints but, more importantly (assuming I've interpreted your intentions correctly) DMS_Accounting_All will actually include the AR,AP and PR flags, DMS_HR_All will include the Employee and CareGiver options and DMS_All will include all flags. This approach can, for example, simplify your filtering. If you want to filter on records with any accounting flag you can just use :

Dim list= (From x In result_Match Where x.SecurityCodes.IncludeIfAnyOf(DMS_Accounting_All) Select x).ToList()
