At the end of a function in VBA what is the "best way" to clean up variables?

1.  Close each object only.

MsSet.close
MyDB.close

2.  Set each object to nothing only.

Set MySet = Nothing
Set MyDb  = Nothing

3. Set ONLY the DB variable to Nothing, even though other variables have been used.

Set MyDB = Nothing

4. Close all variables and then set to nothing

MsSet.close
MyDB.close

Set MySet = Nothing
Set MyDb  = Nothing


Please also tell me why you are suggesting an option.

Thanks.

Hey hertzgordman!

  I do it this way
  rs.close: set rs = nothing
  db.close: set db = nothing

I always try to destroy the objects from the child level up.

regards
Jack

I like your approach.

But please tell me that would be the consequence of NOT setting the objects to nothing.

I have a whole bunch of functions where I am NOT doing this.  Do I need to go back and fix them?

Having "undestroyed" data access objects (Access recordsets/databases) in memory has been alledged to cause Access to remain in memory even after a quit.  It has also been blamed for "insufficient memory" issues.

All I know is that my teacher told me to do it,... it doesn't cost me anything...so I do it.

I would recommend that you correct this "when you are in the neighborhood".  I wouldn't make a huge effort to try and find them all unless you are experiencing memory issues or Access remains in the task manager list after application.quit
