Hi,
On some pages, I put a collection in the session, which uses the InProc
mode. On pages where the session is extensively used (many collections are
put into it), whenever I try to remove an item from a collection using the
RemoveAt method, I get a "Index was out of range. Must be non-negative and
less than the size of the collection. Parameter name: index" error even
tough I verify in debug that the collection count is equal to 1 and I try to
RemoveAt(collec tion.count - 1) (so the index is non-negative and is less
than the size of the collection). And that error occurs if I try to remove
any index from the collection. On the other hand, on one specific page where
I put only one collection in the session (but exactly the same logic and
code apply), eveything works fine. Can someone help me out?
Thank you very much!

try pulling the collection out into a local var, remove the item, then
reassign the session var. i think i've seem problems like this when i
don't explictly reassign it....
but worth a try, and IMHO is actually a little cleaner approach (but i'm a
purist!)

That's actually what I am doing (pulling out the collection into a local
variable, removing the item and puting it back into the session :)

ah, wasn't sure...I have seen people act directly on the Session object,
which I'm not saying that's incorrect (dunno for sure)....

Hi,
I start a new thread about a discussion from yesterday (or for some of us

It started by an example from me, that was far from complete and with typing
errors, but basically it had the meaning to show that removing controls
reversible was the nicest method.
This was a lets say conclusion (but what is that in a newsgroup) in a...

Hi,
I have a problem where I have two requests (i.e. two different windows that
are using the same session) that are accessing the session collection. The
requests will need more time on the server, but I get the problem that the
two sessions are not getting updated values from each requests. Is this by
design or is there any solution to do this?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
