Check if object is set in VBScript

Question

Assume I create an object:

set newcon = Server.CreateObject("ADODB.Connection")

And at some point I destroy it:

set newcon = nothing

How can I tell if newcon is an object or nothing?

I have tried:

newcon is nothing

but I get object required.

If I try isobject or isnull or isempty it doesn't return either true or false.

Is there something else that really works?

I believe you accidentially changed newcon before testing it with Is Nothing:

>> set newcon = CreateObject("ADODB.Connection")
>> WScript.Echo 0, IsObject(newcon)
>>
0 -1
>> set newcon = Nothing
>> WScript.Echo 1, IsObject(newcon)
>>
1 -1
>> WScript.Echo 2, newcon Is Nothing
>>
2 -1
>> newcon = "oops"
>> WScript.Echo 3, newcon Is Nothing
>>
Error Number:       424
Error Description:  Object required
>> WScript.Echo 4, newconn Is Nothing ' oops
>>
Error Number:       424
Error Description:  Object required

If you get Error 434, then newcon (or the variable you really test) doesn't hold an object or Nothing.
