Hi Cetin

>I didn't say send object reference. I don't know if you could. Even if you could sending an object reference instead of a simple key string would impact perfromance I think. Just send the "key".

I am sorry, I hadn't meant that you said it so, but as I studied the help file for the method I just got this thought and ask you just in case you had some experience like that.

In any case you are right about the performance hit. I will stick to the key thing.

Thanks for your helps.
