Hi,
I have an windows application. On button click, I call a service called ServiceA (ServiceA is in my local machine). From ServiceA's method, I hit database and retrieve some records. After retrieved, I call another WCF service called ServiceB (ServiceB is availabled in another machine within network). I have added ServiceB's proxy files in my ServiceA's project. endpoints and bindings are added in wwwroot\web.config. When I try to consume ServiceB's method, I am getting the following error.
Could not connect to http://tde017:8080/AdapterService/AdapterService.svc. TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions 17.21.11.17:8080
Previously, it throws with the port number 80. I configured the another port 8080. Now error is throwing with 8080.
But, If I consume the serviceB directly from my windows application, I am getting response. If I go through another service, I am getting error.
I tried many scenarios. But, still I could not get solution. Any one help me on this....
Thanks in advance.
Regards,
Bala

Dear C# enthusiasts,
I am currently developing a C# application that controls some test equipment and performs functional tests on a product. This type of application is inherently sequential in nature so I have thus far avoided muddying the water with issues of multi-threading.
However, I am dissatisfied with my programs because the UI is not responsive while my functional test loop is running. At the moment the limit of my programming skill only allows for dirty calls to Application.DoEvents() in order to process data on my UI as the test is executing.
It seems, then, that whilst my program is inherently sequential I would benefit from having the UI and the test loop running concurrently. And now we arrive at the core of my question:
What multi-threading method is the path of least resistance for this kind of application given that I am not very experienced in C#?
So far I have read about the background worker and tasks. My understanding is that tasks are the way forwards for .net developers and that it's becoming very important to have a grasp of them. I read some articles about it here on Code Project but unfortunately I have found them difficult to follow. That is a reflection upon my level of competency, not the articles themselves.
I am willing to persevere with tasks to gain full understanding but only if that knowledge is likely to be of significant benefit to me in the future.
Advice and comments are welcome.
Thanks,
Brian.

Brian, see this[^] article. BackgroundWorker may be exactly what you need to quickly get your test harness app to be responsive.

Thank you for the replies both. I take your points and I will be familiarising myself with the background worker over this coming weekend.
By the way, I have heard a few recommendations for Head First C# (the source of the linked article) and I think perhaps I should grab myself a copy.
Kind Regards,
Brian.

I haven't been impressed by the HeadFirst series. IMHO, they tend to oversimplify the material and add unnecessary fluff to the subject. I recommend Programming C#[^] (O'Reilly Press).

Thank you for the book recommendation Ravi. I have just purchased Head First C# via Google Books and already I can see what you mean by "unnecessary fluff". It's probably a good book for someone who is not only new to C#, but new to programming completely. I'm not new to programming and I'm not completely new to C# either. I'm somewhere in between beginner and amateur as far as C# is concerned I think. Still, I don't mind having a beginner's book to hand because sometimes that's just what you need when you're trying to find out about some particular aspect of something.
I have had success with other books in the O'Reilly Press series. Namely Learning Perl, Intermediate Perl, and Mastering Regular Expressions.
I think I will give your book recommendation a whirl!
Thanks again,
Brian.

Background workers will solve this issue for you.
They are real easy to use.
You just have some limits on how you interact with them..
But, by default your UI will run in the same thread and it will freeze if you have some other code that fired off from the ui with no threading.. and that is the problem you a experiencing.
You can use a background worker and fire off the thread and the Dowork sub will then run in the background and will not freeze the ui. I would suggest you read up a little on background workers but they can help a ton with UI freezing issues.

I throughly recommend this[^] website. Its articles on threading are among the very best I've read.

Hi All,
First time posting here, long time programmer..
So, I have a need for custom controls that I am using to dynamically render a list with call backs..
So, far I had no problem doing simple inherited based controls and hooking their callbacks...
IE CusControl : TextBox...
Then its fairly easy to hook the TextChanged event and add the controls a dynamic list and catch the post backs.
Now, the hard part is when I am no longer inheriting the TextBox base control.. but instead I want to create my own control (combo of many controls) and expose my own events to the page that contains my custom control.
For example..
I have a class, and inside the class I create my own controls.
example of the idea..
public class CusParamTextBox : BaseParam
{
public TextBox ParamTxtBox;
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
CreateCustomChildControls();
}
private void CreateCustomChildControls()
{
ParamTxtBox = new TextBox();
ParamTxtBox.AutoPostBack = true;
ParamTxtBox.TextChanged += new EventHandler(ParamTxtBox_TextChanged);
base.Controls.Add(ParamTxtBox);
}
public void ParamTxtBox_TextChanged(object sender, EventArgs e)
{
TextBox cuscontrol = (TextBox)sender;
ParamTxtBox.Text = "fired!";
}
}
Ok, so now I want to expose another event ExposedUpdate() outside of this class..
kind of like a universal update event that I want to be able to hook to the page that loads this control.
So.. inside my ASP.NET Page that contains the custom control I want to hook my own event somehow.. something like this...
CusParamTextBox tmpctrlx = new CusParamTextBox();
tmpctrlx.ExposedUpdate() += new EventHandler(this.Update);
protected void UpdateText(object sender, EventArgs e)
{
CusParamTextBox cuscontrol = (CusParamTextBox)sender;
DosomethingOnPage(cuscontrol.name,cusontrol.value);
upMain.Update();
}
The idea would be, that the local event fires off on TextChanged then fires off the other ExposedEvent that would then be hooked into the main page to fire off more code on the main page.
Any idea or am i off the rocker and there is a better way to do this ?
=)

The site let me post twice during the process of writing a single post.
There was no confirm, and when I hit a hotkey and my work posted instantly..
Then I clicked back and it let me edit the text I was working on and then when I clicked post again it created a new post and posted again instantly.
Ultimately the problem is both user error on mypart and also software error on the forums part.
I am new, so I did not realize what just happened.. and the software did not detect that I posted twice from the same exact page...... I quick guid check or confirm could of taken place to prevent me from double posting.. And I could of stopped it if I realized it.
So, I apologize for my mistake, but I cant take all the credit!

If you had hit "Post Message" without editing, our system would have rejected the duplicate post. As it stands, you edited the text and hit send so our system thinks you simply posted a new, different message.
When you posted the original message you would have seen, just under your message, links to edit or delete your message.
We will be making changes that will make it even harder to repost accidentally.

So you just want to expose an event from your custom control?
public class CusParamTextBox : BaseParam
{
public event EventHandler ExposedUpdate;
protected virtual void OnExposedUpdate(EventArgs e)
{
var handler = ExposedUpdate;
if (handler != null) handler(this, e);
}
...
private void ParamTxtBox_TextChanged(object sender, EventArgs e)
{
...
OnExposedUpdate(e);
}
}
...
var tmpctrlx = new CusParamTextBox();
tmpctrlx.ExposedUpdate += Update;
...
protected void Update(object sender, EventArgs e)
{
var cuscontrol = (CusParamTextBox)sender;
DoSomethingOnPage(cuscontrol.name, cuscontrol.value);
upMain.Update();
}

Yes, I want to expose a event that I can hook too.
So, I can tell it to fire in the local control... but pretty much do nothing locally... but then hook it to a page event that will do the heavy lifting.

So, pretty much exactly the example I posted then?

Yes, Thank you so much!
That is working like a charm!

Ok, I do have a new problem now..
It seems when I put this code into my update panel...
It continues to do a full post back all the time...
Any idea how how to solve this any one ?
Thanks!

Have you added an AsyncPostBackTrigger[^] for the control?
<asp:UpdatePanel runat="server" UpdateMode="Conditional">
<ContentTemplate>
<uc:CusParamTextBox ID="CusParamTextBox1" runat="server" OnExposedUpdate="Update" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="CusParamTextBox1" EventName="ExposedUpdate" />
</Triggers>
</asp:UpdatePanel>
