Error - Operator '=' Is Not Defined For Type 'DBNull' And String "test"

Feb 23, 2010

I have the following query

Dim get_rmf_2 = From rmf In t_rmf _
Where rmf!NIVP = nivp_rap

When i run it i get an error :

Operator '=' is not defined for type 'DBNull' and string "test".

I suspect this is because the column "NIVP" in the datatable contains null values, I've tried yhe same thing without null values and it works.So how can i make this work ? ; the column "NIVP" really has a row "test" , and a normal SQL query works fine.

Error: Operator '=' Is Not Defined For Types SERVs_up.PCANLight.CANmsg' And 'SERVs_up.PCANLight.CANmsg'

Feb 19, 2010

I get this rather odd error, at least I don't understand it. I have defined a structure under the namespace "PCANLight":

Public Structure CANmsg
...
End Structure

PCANLight is imported in my main program:

Imports SERVs_up.PCANLight

Later in the program i use the following statement:

Dim dummy As CANmsg = Nothing
If dummy = Nothing Then
...
End If

This gives the error: Operator '=' is not defined for types SERVs_up.PCANLight.CANmsg' and 'SERVs_up.PCANLight.CANmsg'.

Do I have to overload the operator = for my structure or what?

I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.
