Recently I have tried to create a MTDLL in VFP which utilizes a FLL, specifically VfpEncryption.FLL. When trying to use an encrypt /decrypt method I ge the following:

System.MissingMemberException was unhandled
  Message="No default member found for type 'Boolean'."
  Source="Microsoft.VisualBasic"
  StackTrace:
       at Microsoft.VisualBasic.CompilerServices.Symbols.Container.GetMembers(String& MemberName, Boolean ReportErrors)
       at Microsoft.VisualBasic.CompilerServices.NewLateBinding.CallMethod(Container BaseReference, String MethodName, Object[] Arguments, String[] ArgumentNames, Type[] TypeArguments, Boolean[] CopyBack, BindingFlags InvocationFlags, Boolean ReportErrors, ResolutionFailure& Failure)
       at Microsoft.VisualBasic.CompilerServices.NewLateBinding.InternalLateIndexGet(Object Instance, Object[] Arguments, String[] ArgumentNames, Boolean ReportErrors, ResolutionFailure& Failure)
       at Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateIndexGet(Object Instance, Object[] Arguments, String[] ArgumentNames)

Is anyone familiar with this one?

Thanks
