Error: Specified cast is not valid

[Web Team @ Borough of Poole]

Hi All,


When I run the below code, I get error 'Specified cast is not valid' on
line

163 Dim Address As OldInfra.BS7666.Address =
BS7666AddressCollection.GetSingleAddress(str_UPRN)

164 Dim easting As Integer = Address.Easting
165 Dim northing As Integer = Address.Northing

Address.Northing is an Integer in my class:

Me.Northing = CType(DR("Northing"), Integer)

Any advice anyone?


Thanks,
Simon.

User the debugger to see what kind of object is Me. Northing is OR do a
Response.Write("Me.Northing is of type: " & Me.Northing.GetType())

If you do not get Integer as your output then yeah, that cast will be
incorrect

Also, turn Option Strict on

If Northing is Nothing, that would do it.

Make sure DR("Nothing") isn't DBNull? Not sure what DR is, though...

Thanks everyone - Northing was indeed Nothing!
