WCF / ASMX :: Read And Modify Soap Message (Programmatically)?

Apr 1, 2011

I have a web service running somewhere... I have added a reference of the same in my project. I had used SOAP UI to check the outgoing and incoming SOAP messages.

Now what i need is to MODIFY the SOAP message after it has been created (I wont be creating the soap message manually,) modify as in, I mean to insert some element into the header (such as public key etc) and encrypt the contents present in the body.

I have tried a lot of googling and have come to conclusion that i may have to use the SoapExtension Class.But i just dont understand how to do it.

There are method like ProcessMessage(... which require SoapMessage as input parameter. Now how to read
a generated SoapMessage is still unclear to me. I dont want to read the Soap message using tools (fiddler, soapui etc). I wish to read it programmatically.

First for lower version database process runs smoothly using Database Publishing Wizard, all process completed but when execute script the result of published database from SQL2005 in database SQL2K, the exception is occured.

How that happened ? Is database from SQL2005 has maximum capacity that in database SQL2K can't handle it or other things ?

Is there any solution so that I can get that database used in SQL2K ?

DataSource Controls :: Trying To Sort A DataTable, And Not Always Succeeding?

Apr 27, 2010

I am trying to sort a DataTable. If I declare a DataView and use the following approach it works perfectly:

Dim dt As DataTable = getData()
Dim dv2 As New DataView(dt)
dv2.Sort = "surname, name"
dt = dv2.ToTable

I wanted to do this without using a DataView though if possible to reduce the impact on resources. I tried the following approach but it doesn't work. I might be writing the code wrong so

Dim dt As DataTable = getData()
dt.DefaultView.Sort = "surname, name"
