About Function "FindNode"

I want to find some DiagramNodes which have specific Tag.
So, I tried to use FindNode Function.
From Guide, when finding Node fails, that function will return Nothing(null in C).
However When I use findnode like below, I just got error message.

if Diagraminstance.FindNode("SomeTag") = nothing  then
.....
end if

Message saids 'For MindFusion.Diagramming.DiagramNode, '=' operator is not defined'

How can I solve this problem?

I think VB.NET expects you to use the "is" operator. Try this:

if Diagraminstance.FindNode("SomeTag") Is Nothing  Then
...

I hope that helps,
