Greetings,



After reading, inserting, deleting items in an Access database using ADO, I always close the connection, but do not dispose of the objects or set any of them to nothing.  I do not seem to have any problems but need some opinions,  (examples if applicable) as to whether or not this is a good practice. I am using vb through vs 2008.

Thanks

I understand there is something called the 'Garbage Collector' built-in to .Net that disposes of unused objects, but IMHO it is always good programming practice to dispose of unused objects if you have instantiated them.  I believe you can also call the garbage collector directly (GC.Collect?!?) but I would bow to someone with greater knowledge of .Net on that point.

It is good practice to get used to disposing of objects as soon as you are finished with them as garbage collection is non-deterministic (meaning it is unknown when it will clean up your unused objects).
The best way to ensure good disposal is the use of the using statement as the object is automatically disposed of at the end using.

Using cn as New SqlConnection(myConnectionString)
