valid object reference

[lvrat]

I have a station global object reference. Is there a way to check if the object reference is valid?

Thanks.

I have a similar issue where I need to know if a session number is still valid before I try to close it.  I have cleanup steps that close references/sessions/handles, etc. in case an error occurs in the sequence, but if no errors occurred, then they should already all be closed.  Would the "!= Nothing" be valid for everything?  Thanks.

Hi GSinMN,

The Nothing constant refers to empty ActiveX references.  You can find more information about it here:
