Hos do I find out if an object exists?

[joewilson]

If an object has not been set, its value is "Nothing" and reference to it will give an error. Is there a way to see if an object exists?

For example, I need to look at the nodes of a TreeView and determine the parent of each node. Node.Parent causes an error if there is no parent.

You can test it in a If statement

If myObject is nothing then
Msgbox "Object not set"
End If

Excellent. Sometimes the obvious is hard to see.

Sorry about the typo in the title.
