Hello George, consider EPRs as a way to connect a service endpoint. If you look at some examples you might see ReplyTo header which contains Address, reference parameters or metadata. This means that the client which sends such request to a provider, expects a response to the specified address in the ReplyTo, with supplied reference parameters and maybe some metadata. Like the client, the provider may also offer special communication with endpoint instances. The wsdl contains the information for provider's endpoints. Different bindings could be set for calling endpoints with reference parameters for example. Consider such provider as an EPR itself. The request's wsa:To maps directly to the provider's destination URL. Reference parameters are set directly as separate headers with wsa:IsReferenceParameter attribute set and so on. You need to look for some ws communication with all of the combination and headers in use. You can find a part of the W3C org tests of WS-A here: http://dev.w3.org/2004/ws/addressing/testsuite/testcases/#test1100 Particular implementation means that you can write your own Addressing SOAP feature with any language. You can write it as you like. You can follow the specification or you may not follow everything in the specification, but if you don't, you risk to have not an interopable implementation with third party vendors. Interoperability is a key moment in web service communication. Endpoint address information could be found in the wsdl or some metadata or address of an EPR. If the anonymous client URI is used (SOAP over HTTP) then the Reply is returned on the same HTTP connection. Serialization is transformation from the property data to an XML infoset. Deserialization is the oposite. Best regards, choopie

Hello George, Message Addressing properties are the properties or attributes of a particular WS-Addressing implementation objects. In runtime execution they hold the data in the memory before you serialize them as headers within a SOAP envelope for the "wire" transport. The other way around, the dispatcher of SOAP messages with WSA deserializes the headers' information into runtime objects or properties from the transport protocol. EPR is an XML element of type wsa:EndpointReferenceType. It is a structure which you can use to convey specific endpoint instance information, or just reach particular endpoint or instance of a service endpoint. The ReplyTo, From, FaultTo headers are types of EPR. They bring information how to reach an endpoint in different ways and cases. Best regards, choopie

Hello everyone, does anyone know in which language the following expression is a valid loop: (i. >./) >./ x Thanks, choopie

Hello all, I use VS2008 and .Net Framework 3.5. I have created a simple WCF web service and hosted in IIS 5.1. Then I've opened it's WSDL from the browser and there in the endpoint address I see the FQDN except the name of my computer in the DNS or the IP address. For that reason I am unable to open the WSDL from some other computer. Maybe it is masked by NAT I don't know. I have a firewall working on my pc by the administrators too. I could change the address of the service endpoint in the Web.config file but could not change the addresses of the schemalocation. I'm new to this stuff, so please could someone help me or explain me why this happens. Thanks and Regards, ~choopie

Great! I'll try it. Thank U.

Thanks Luc!

Is there a way I can access to the definition and implementation of the members of the TcpListener class?

Brilliant!! Thank you :)

I mean when I start the OpenConnFunction() in a separate thread the animation starts otherwise not :(

Thanks for the reply. Unfortunately, your suggestion didn't help me. I think I need to call the OpenConFunction() in a separate thread. But I don't know how to start the AfterConnFunction when OpenConFunction ends.

Hello fellows. I need your help. I have a Windows.Forms application which makes a connection to a database about 5 - 10 seconds. While I'm trying to connect to the database, an animated control starts an animation . After the connection is made I stop the animation and want to run another function to fill a DataGrid control. private void OpenConFunction() { //... some code } private void AfterConnFunction() { //... some code to fill DataGrid control } private void myButton_Click(object sender, System.EventArgs e) { Thread t = new Thread(new ThreadStart(OpenConFunction)); t.Start(); this.AnimatedControl.Start(); //Suppose AnimatedControl //has two methods one to start animation and a second one to stop it } What has to be the code after OpenConFunction returns? I want to invoke the AfterConnFunction and stop the AnimatedControl animation?

Well, the point is that I couldn't join two tables from different data sources. One table from SQL Server database and another one which is represented as a file in AS/400 machine. I'm sure this will make you wonder :doh: why I need such data to join from these sources. This is not designed by me I only have to make this join and sum the Amount values by Month. But I couldn't. I only succeeded to make a connection to each of the sources and to select the data without the join (just for test). The file in AS/400 contains the Amount values and some other columns. The months i take from SQL Server table. I prefer using SQL in separate logic layer too but in this case the join doesn't work. Maybe I'm wrong to not to keep trying it with the SQL. I thought it might be easier to do it in C# class. :confused:

Thanks for the help Mike.

Hello Mike, I'm talking about this: DataGrid columns Column1 Column2 ----------------------- Month Amount 02.2007 60 02.2007 30 03.2007 50 04.2007 60 I want to add rows in the grid which sum the Amount values by Month like this: ----------------------- 02.2007 90 03.2007 50 04.2007 60 ----------------------- I need C# class not a SQL statement

Hi everyone. I have Windows.Forms.DataGrid with two columns. The first one has string values which may repeat in the column. The second one has integers. My question is how can I sum the integers where I have string values which appear in more than one row in the first column? I need something like the "group by" clause in a sql select statement.

Can you write me an insert statement to insert an integer and a Date data types values in dBase dbf table?

Hello everyone! I have experienced problems with setting the connection string when I try to connect to a file of type DBF (dBase, FoxPro) and OleDbCommand for the insert statement (both by code). I use Visual Studio 2003? Can anybody help me to manage with this? the source is c:\myTable.dbf the insert statement: use myTable insert into myTable(someColumn) values ('string') Thanks in advance!

Thank You!!!

Hi all, I just listen a socket for permanent data and want to save it in a file. Can anybody help me? //Socket socket = ... NetworkStream ns = new NetworkStream(socket); Int32 i = ns.Read(bytes, 0, bytes.Length); while (i != 0) { //Code here }

Thanks but still it should return to me any data without appending.
