How can I compare 2 treenode elements.

When do you consider two treenode objects to be equal?

If you want to check if two variables reference the same 'TreeNode'
instance, you can use 'If t1 Is t2 Then...'.

Herfried,

Is this not "Is the same type of object?

Amruta,

Assuming that you set forever the same type of value in a tag than you can
cast it in whatever way.
Assume this
a.Tag = "Amruta"
b.Tag = "Amruta"

Than
a.Tag.ToString = b.Tag.ToString
will go

or if it was an integer value
Cint(a.Tag) etc.

I hope this helps,

No.

You mean that two variable can reference to the same ojbect which are(is)
not from the same type of object?



I misreaded it and wrote it even wrong.

Well, as you know for sure, object identity implies that there's only a
single object ;-).
