Writing Data to database with jQuery Forms, ASMX Webservice, & JSON - help!



Can someone point me in the right direction on how to submit data from a jQuery form to a ASMX webservice? I have gotten everything on the form ready to be submitted to the database and now I am stuck on how to send it over using $.ajax(). Everything I have read tells me how to get data from a webservice and display it with jQuery, but not the other direction nor how to access the json data within the within the webservice service(similar to a Request.Form approach with ASP.NET forms).

In other words: 

1. What do I need to do to my webservice to make sure it can receive data from the jQuery form. 

2. What do I need to do in jQuery to receive an acknowledgement the save on the server side was successful. 

I can explain more if need be, but if there is a comprehensive tutorial on not only reading, but also WRITING data with jQuery, JSON, etc. I would love to get pointed in that direction. 

Writing to a text file



I have the following  subroutine in an asp.net application class. The subroutine writes data to a text file upon application login.   My question is that if this function was called at the same time by two different  users would it cause any kind of error. Is there a need for a try catch?

 Public Shared Sub writeToLogFile(ByVal UserName  As String)
        Dim strLogMessage As String = String.Empty
        Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt") Dim swLog As StreamWriter
        strLogMessage = DateTime.Now.ToShortDateString().ToString()  " ==> " & UserName

        If Not File.Exists(strLogFile) Then
            swLog = New StreamWriter(strLogFile)
            swLog = File.AppendText(strLogFile)
        End If

Join 2 flat file data flows - retain unmatched rows

I have two data flows from two separate flat files. They may contain matching IDs (account number), in this case specific data from each flow should be used to create one row. When there is no match, the rows would stand on their own. At the end of the flow, I need both flows combined into one flow, with one record for each key record (account number). If I were able to use a look-up, I could easily union the no-match data flow back into the match data flow and have the desired result. I cannot use a look-up, since the source is flat files, but this is exactly the functionality I am trying to achieve. Solutions I want to avoid: staging tables, and cache transformations. Any ideas are appreciated.
