Hello,
i'm writing a WCF Application and need to know, which IPAddress/Port i use to communicate with the WCF-Service. I don't want to know on which Port i'm connected on the Server (RemoteEndpointMessageProperty), i want to know which IP/Port my network card uses to connect to the Server.
I hope you can help me.
Thank you

Assuming you are using a DuplexClientBase<> derived class, you can use client.Endpoint.Address where client is an instance of the derived class.

Hello,
thank you. But i use the DuplexChannelFactory and there i have a client.Endpoint.Address, but i get back the Address from the service. So what to do now?
Thank you

I haven't any solution yet...
I tried this with "OperationContext.Current.OutgoingMessageHeaders.From" on local side, but there's no success. 
Is it so difficult to get the IP Address from where i send a message? Or if it's a incoming Callback-Message to get the Endpoint on which the Message came in?

Hello everyone,
ActiveDB.DBContractsClient _Proxy = new ActiveDB.DBContractsClient();
_Proxy.Open();
_Proxy.ExecuteQuery("Select 1", new object[] { });
_Proxy.Close();
_Proxy.Open();
_Proxy.Close();
I have the following code to demonstrate my problem. Till the point where is the second open it works fine, but when it tries to open to connection for the second time it says cannot open object because it is disposed.
Am I doing something worng or any ideas on how i may fix it?
Thank you for any help.

It looks like _Proxy.Close automatically disposes of the object. I'd take a look into that if I were you. One way round it is to create a new instance of ActiveDB.DBContractsClient before calling the second _Proxy.Open.

The Issue is that I want to use the same instance i am using this in a web application and what I am doing is that I am creating this instance when the session starts and use the same instance for every operation that the user does in the application. And for every operation I want to open and close the connection to make sure that no connections are ever left open.

You can't have it both ways unfortunately. Either it's disposed and you create a new instance every time, or you have to leave it open. It would be easier if you had control of the class itself, and could remove the Dispose out of there, but it looks like you don't have that option.

And why do you want to do that?
What benefit do you think that you get from that?

I was playing with WCF last spring, not with a web whatsis, and only opened the connection once, so I didn't encounter that.
I'll take a look at what I can find out later.

Try asking at the article itself - that way the author gets an email - posting here relies on them "dropping by" and realizing it is for them.

Which of the many available Methods are you using to load the bitmap?
I suspect that you are using Image.FromFile() as this is a well documented problem with this method.
If that is correct then switch to Image.FromStream() (look it up). Hopefully this will resolve your problems.

hi sir,
i am using filestream only.. one more thing i am using thread to load the controls inside layout panel
regards

In that case, without seeing any code, is there a possibility that the threads are terminating before properly closing the streams?

In order to be able to delete a file, everything that points to the file must have been disposed.
Candidates are: Image.FromFile, Image.FromStream, PictureBox.ImageLocation
The problem here is you have to do special things at the end of the PictureBox's life; if the image is used in more than one location in your code, it may be hard to correctly decide on its disposal.
There also is a different approach, where the problem is avoided beforehand, by copying the image; this is a schematic example:
Image image1=Image.FromFile(...);
Bitmap bitmap1=new Bitmap(image1);
image1.Dispose();
PictureBox.Image=bitmap1;
...
myForm.Close();

Hi ,
I am trying to create an application to extract some txt files from ZIP and then search the text files for a search string.
I have done two functions
1. That extracts the files
2. That searches through the files
This is my required program flow.
I need to threads to run here
The first thread should concentrate on searching the file, extracting them and add the extracted files's to a string array and the second thread to monitor that string array and search the newly added files for the search string.
Is this possible? I have done some coding for this. Will post it later in this message thread if required later.

Yes - I'm not sure it's the best possible design, but it is possible. What you could do (if you are using .NET 3.5 or later) is use an ObservableCollection in the first thread which the second thread hooks into the event handlers for to see when items are added into that collection - then it can perform it's searching in response to the item changing.
Alternatively, and this is perhaps a better method, you could have your first thread implement an event handler that takes the contents of the file as a parameter (assuming you are just storing it as a big string here) and the second thread hooks into that event. Obviously, you'd fire off the event every time you added a file.

Help to create a simple file manager that can do following things:
- Browse the directories(forward and back functionality);
- Change the current driver(from C:\ to D:\ or to flash);
- Pre-view and edition of the file with the short-cut key(F4) –
only for txt files;
- The icon with functionality that allows the user show or hide
hidden/system files and folders;
PLEASE HELP

You should read some CodeProject articles, maybe this one for starters: C# File Browser[^]

edit, delete
Actually i am adding this value through checkbox. when i select checkbox, the associated value ('edit') has been added in database, when i select another checkbox, the related value ('delete')has been added in the database. basically i can select two or three checkox, all concerned value has been added and seperated with 'comma' in same column.
My query is , I want to edit this data. when I select edit button, the value of the checkbox shows 'true'.
e.g. the 'edit' related checkbox shows 'tick' and so on.
thanx and regards,

This is the C# forum. You don't state what you are using this in.
Is it a web page, WPF, or Silverlight application? It makes a big deal as to how to do things based on where you display it.

Take a look at the Passport section here[^] for details of the format. You could have found this information yourself easily enough, by using Google to search for ICAO line passport - that's what I did and the first link took me to this page.
