How do I remote an array of objects?

=?Utf-8?B?cm9kY2hhcg==?=

7/15/2004 1:18:00 PM

I need to send a collection\array of values from my
client to my remote server (hosted by IIS). I have tried
an array of Objects and an ArrayList. Neither will
remote. What type can I use to send an array of 'other
types' (string, datetime, decimal)?

Hi Greg,

array of object should work. Make sure that the objects you have in the
array are all [Serializable], otherwise the serialization will fail.

Btw, what you mean by "neither will remote"? Please, post the error you
receive.

The types in the collection, or array, are
System.String

System.DateTime

System.Decimal

System.Byte[]

My object array contains the following types:

System.String

System.DateTime

System.Decimal

System.Byte[]

The exception is a general remoting exception.

Still I do not see your error message.

System.Runtime.Remoting.RemotingException

Message: Server encountered an internal error. For more information, turn on
customErrors in the server''s .config file.

Exception rethrown at [0]:

at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage
reqMsg, IMessage retMsg)

at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData&
msgData, Int32 type)

Here is the signature for the remoted method:

Public Overloads Function UpdateDataset(ByVal dsChanges As DataSet, _

ByVal transaction As SqlTransaction, _

ByVal spName As String, _

ByVal buildParamValues As Boolean, _

ByVal tableName As String) _

As DataSet

The 6th param used to be an array of objects. I have removed for testing.
I still get the same remoting exception though.

well, I removed the SqlTransaction param on the remote server and it worked.

So, it seems you cannot send a SqlTransaction to a Remote Server? Why not?

Hi Greg,

please, turn on customErrors at the server, so you receive the full
exception.

Also, there are some problems with datasets via remoting. But there is
easy workaround, which works for me. DataSets are always serialized to
XML, both with binary and SOAP formatters. So what you can do is to use
DataSet''s write to xml capability, and pass that xml string over
remoting. On the other side, just reconstruct the DataSet from the
string.

You can.

The problem is somewere else.

If you can be so kind to answer to my other post, and to provide the
full error, noone can help. Also, how do you register the channels at
server and at the client?
