Hi Gwyn

Although a bit perverse, you could reverse the test, as

Select Case True
Case TypeOf obj Is MyClass
...

Case TypeOf obj Is MyOtherClass
...

Case Else

End Select

Hi, often I want to do different things depending on the type of an
object...

I end up having to use:

Select Case myObj.Gettype.Name
Case Gettype(AClass).Name
.. process as AClass
Case Gettype(AnotherClass).Name
.. process as AnotherClass
End Select

Is there a better way to do this cos it strikes me as being a bit naff?!

Cheers.

Usually, you do it by polymorphism instead (e.g. make all the classes
implement a common interface, and call a method within that interface).
Otherwise, the above will basically work, and I don't think there's a
much better way.
 
Very nice. Thanks a lot
