Hi Gil,
I assume you are wanting to apply WCF to an existing application? Michele Bustamante has a good example here:
Hello Indigo[^]
This is taken from Chapter 1 of her book, Learning WCF. I do not own this book but it has had very good reviews.
The whole of Chapter 1 is available in PDF (and also at the link provided) and you can also download the source code for the book. The book was for VS 2005 .NET 3.0. However, she has also provided source for running in VS 2008/.NET 3.5.
Chapter 1 is actually an excellent step-by-step introduction to WCF where she uses one simple API ("Hello Indigo") and works through all of the different scenarios for using WCF with it. I've worked though a number of the examples, though I haven't yet tried the one described.

Hi Kevin,
As I wrote to Mika, I'm not quite sure what my client ment by SOA interface
I need to ask my contact guy to ask the client for more info
I assume WCF is one way to provide the SOA concept, right?
Cheers
May the source be with you

Yes. And if you're in the Microsoft world (which you most likely are if you're using C#) then this is the way to go. Once you've provided a WCF contract you're service will be accessible from any platform and any language.
However, if you're confined to .NET 1.x or 2.0 then web services is the way to go.

Hello everyone,
I have read a few WSDL documents and toturials, but find nothing covers how to add SOAP header for some web services port operations in WSDL file.
Does anyone have such referral documents or books?
thanks in advance,
George

Don't have any books in mind, but technically adding a SOAP header is described for example here.
SoapHeader Class[^]
I don't believe that you can add a header to a port (unless you write custom logic to handlers), but you can add header to web service and divide different services to different ports.
Hope this helps,
Mika

Hi Mika,
My question is how to add SOAP header to some web methods in raw WSDL file, not modify the web services code to generate SOAP header as the link you referred shows.
Any comments or ideas?
regards,
George

Never done that before, but I would create a web service without header attributes and a copy of that web service with another name and with soap headers. Then, I would get the wsdl-files and compare them to see what has to be modified and how.
This isn't elegant aproach, but perhaps it would help  ,

Hi Mika,
I have already done what you described. But I think a more comprehensive document about how to add SOAP header and a sample would be greater! Any referral documents or forums/maillist to ask the question?
regards,
George

Thanks Mika!
I like the document you referred.
Any more comprehensive tutorials or documents describing the SOAP header related fields in WSDL?
regards,
George

You're welcome.
Sorry to say but I've got nothing else in mind since I usually let VS generate the necessary definitions for WSDL.  Hopefully google will help you. Especially W3C related sites...

Thanks Mika,
Let me know when you have any more readable materials on this topic in the future. I am reaing w3 sites now, but not quite readable and boring.

hi,
this is exactly my first program, i will be using C#. The device i am using is a usb connected PC digital TV receiver this receiver software actually have a function which measure the signal strength, BER and these data are save into an log file (thus it real time measurement data) once i start the device (start watch TV).
I am suppose to use C# to get the real time measurement and convert it into graphic (line chart).
I have try to get the data for the log file and display it in the textbox using the following code
using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace Testing_1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
StreamReader objstream = new StreamReader("c:\\measurement.log");
textBox1.Text = objstream.ReadToEnd();
}
but this is the error i got : IOExpection was unhandled the file been use by another program.
I also try another method which is directly from the usb port which the device is connected to but i am unable to start working on it coding. i had been looking into example of usb_hib and ICSHARPUSBlib but i was unable to get anything out.
Thus please help me, if i am in the right direction (get the data from usb directly?) or do you have any better item on how i should get this done, any code to refer to.
thank so much

Sad to say no progress at all. I think i would have to get the data from the usb port but i have problem programming even after looking at the code from some example to be correct i don't even know how to start with it. I think i will be dead drop.
Anyway thank,would be nice if you have any recommendation for me.

I think the reason for the answer is obvious : "c:\\measurement.log" is being used by another program.
Instead of reading the log file and displaying the results, you should directly get data from the usb device.
yefeng_law wrote: I also try another method which is directly from the usb port which the device is connected to but i am unable to start working on it coding
Why? have a look at the examples and if still can not solve contact the manufacturer of the device for library. Thats the only way I think.

I want to be able to put all the info and to connect and retrieve data into an app. In VB.net I used to make a seperate vb module that I would access from the main form like this
From a button click
getData()
and in the module the function is called getData()
this all worked great in VB and it kept my main form and all the "data modules" seperate. They were easy to maintain and troublshoot.
How would I do this with c#.dot? I have tried making a seperate class file but I cant figure out how to call it. The above procedure does not work the same as it did in VB
