Hello,
I'm currently using Remoting (HTTP/Binary) to remote a simple object.
Everything is working fine except for one function that returns an arraylist
of datatables.
When I call this function, nothing is returned (ie length of array =0).
However, if I comment out my config file so that the DLL is run locally
instead of remoting it, everything works fine!!
So, my question is: Is there anything special that I need to do in order to
return an arraylist of datatables? Note: If I return a single datatable it
works fine, just the arraylist of dt's dont seem to work via remoting.....
Thanks in advance,
-ZD 2 4324

Hi,
and what happens if you return an ArrayList, which contains some strings
only?
I this works, that as far as I remember there was some problems with
datatables/datasets with remoting. What you can do is to create a
dataset, which holds all these tables. The you export this dataset in
XML string and pass this string over remoting. You are not going to
loose any performance, as datasets are always serialized to XML, even
with binary formatter. Then on the client side you can recreate the
dataset from the string and access the tables. Nor very elegant
solution, but it should work.
If passing the arraylist with strings does not work, than most probably
you have some remoting configuration problem.
Also, you may try to capture the appdomain.Resov e event and see if
during the serialization/deserialization there is some assembly missing.

Sunny,
Thank's for your reply.
The problem was that my remoted object was exposing an arraylist as a
property. Apparently doing: RemoteObj.Array ListProperty.Ad d(something)
doesn't seem to work. So instead, I've had to replace the property with a
method that accepts an arraylist as a parameter and then I set my internal
arraylist variable equal to the param. that was passed in. Now things seem
to work fine.
Any idea why that doesnt work?
Thanks

I’m trying to build a generic Publisher-Subscriber that will work over the

I wish that the subscriber user will be notify about the messages sent by

The trouble is that this delegate must not be static because there may be
many subscribers, and each subscriber may have different...

Hi all,
I have a listbox that is complex bound by an arraylist. The problem is that
when I delete an object from the arraylist, the listbox does not reflect
those changes. I tried refreshing the listbox with no luck and, because it
is already bound, I can't just delete the item directly from the listbox
without an error (because it already has a datasource, you are not allowed
to delete/add anything to the listbox directly).

Hey,
I Tried to bind a DataGrid to an ArrayList, and had 2 problems:
1. The DataGrid shows the Length property of the items instead of their
text - how can I change that?
2. After binding, I add new elements to the ArrayList but the DataGrid
doesnt refresh's it's view - I have to set the DataSource property of
the DataGrid to Nothing and then re bind it to the ArrayList! Isnt
there a "pretier" way?
Thanks ahead

I've a datagrid whose datasource is an arraylist object. The arraylist
holds many instances of a specific class.
I've two questions about this:
1 - Is there a way by which I can obtain a reference to the arraylist item
the current row points to?
2 - Is it possible to sort the grid?
Many thanks in advance.

Wondering the best way of storing my data.
This is data pulled and stored in the database but a lot of data
manipulation goes on the client side. I never have to remove items but
will sometimes clear them all out. It seems to me the best way,
resource wise, would be just a string array and then use redim when I
have to add a new "row" of data. Arraylist & datatables seem easier to
work with, but since I don't need much of the extra's...
