[VBA] Determine if a variable has no object

I want to determine if a variable contains a valid shape.

Here's what I'd like to do:

dim aShape as shape

<snip lots of code that may assign a shape to the variable aShape or
not>

if not isNull(aShape) then
'only perform this section if aShape has a reference to a valid shape
end if

<some more code>

I tried isNull, isEmpty, isError but none of these work.

Any ideas? Thanks...martin
 
Try
IsObject(aShape)

If aShape is Nothing then
msgbox "Nothing here"
Else
msgbox aShape.Name & "'s the name, PowerPoint's the game"
End if
 
You're right (of course). I had used it on an ugly bit of code (long since
trashed) to assess a variant type. If the variable is dimmed as a shape,
then the content, or lack thereof, does not matter: IsObject always returns
True.

I think that'll tell you what the variable was dimmed as, empty or not.
