Hi,

For some tables it is very useful to have a fields that will tell the user when was the record changed and by who. 

• Is there anything in SF logic to auto update this kind of fields?
• If these fields should be updated manually what would be the correct event to use to have these fields updated?

Thansk!

I've been messing around with this and have run into a problem, born from pure ignorance.



How do you get a serializable object into a Byte array()? It's probably simple, but I'm not getting it.



Thanks!

Since it is a byte array, you can put anything you want into it.  You can read a file from disk into a byte array and dump it in there, or whatever you want.  It doesn't have to be serialized, it just has to be formatted as a byte array.  When the reader becomes available, we will provide a delegate that will allow you to attach any type of reader you like so you reverse what you did going in and show it to the end-user however you would like.  But if you want to serialize something and convert it into a byte array, here is a sample of how to do that:

Way too easy...



Now, how do I get byte array back into the object via deserialization? Or probably more to the point, how do I turn the array into a memory stream?

Here is an example if you have a file saved to disk.  In the auditing sample, the byte array will be given back to you through the delegate, so you would skip the part of loading the byte array.

Thanks! I'm not too familiar with the IO class and streams. I was having trouble getting the byte array into the stream. Again not too hard once you understand it!

Thanks for the help I got it working. However I had to wrap the deserialize call in a try/catch as it always threw an serializationexceptions:
