Repositioning an Instream to the beginning

Hi All,

I created an InStream and am reading from it using the Instream.READ method.
For the logic I'm trying to do I want to make 2 passes on this stream.
Now after the entire stream is read, is there a way to reposition it so it will read from the beginning of the stream again for the 2nd pass?

I tried copying the InStream to another temporary InStream before the first pass to try to save it, but that didn't seem to work.

Thanks in advance!

    In my understanding this is impossible, as stream is just address in memory, so if you even copy it will refer to same memory address range. I am not sure how exactly NAV streams works, but other memory streams works as I said :)

    But, you can steam you data to temp blob, and then stream out to another stream when you need to do second pass. Define a rec. variable tempblob referring to temp blob table - and you are allright.
