    - LAN Search Just try to establish a connection on every possible IP-address within the sub-net. The sub-net mask is usually 255.255.255.0 so you would try any address from, say, 192.168.1.1 through 192.168.1.255 Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - AppDomain memmory usage size I don't think there is any way to get the size of memory used by an appdomain. If you know which appdomain is leaking memory, you may moniter the process memory usage, when it grows to certain level, you can unload the appdomain. Another way could be using perfmon to monitor the process. Thanks Alicia Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - resizing clipping path Use the Graphics.ScaleTransform() method to get your image to resize, then adjust your path with GraphicsPath.Transform(), using the Graphics.Transform property. Then call Graphics.SetClip() and draw the image. Admittedly, I haven't tried it. Ought to work though.

    - check if a url exists Use HttpWebRequest and check the statusCode in the HttpWebResponse... (A HEAD instead of a GET request is sufficient to do this) eg: Code Snippet Uri uri = new Uri("http://www.timvw.be"); HttpWebRequest httpWebRequest = WebRequest. Create (uri ) as HttpWebRequest; httpWebRequest. Method = "HEAD" ; httpWebRequest. AllowAutoRedirect = true ; // we'll use the Async pattern... httpWebRequest. BeginGetResponse ( this . GetResponseCompleted , new object [ ] { httpWebRequest, uri } ) ; private void GetResponseCompleted ( IAsyncResult ar ) { object [ ] objects = ar. AsyncState as object [ ] ; HttpWebRequest httpWebRequest = objects [ 0 ] as HttpWebRequest; Uri uri = objects[1] as Uri; HttpWebResponse httpWebResponse = null ; int httpStatusCode; try { httpWebResponse = httpWebRequest. EndGetResponse ( ar ) as HttpWebResponse; httpStatusCode = ( int ) httpWebResponse. StatusCode ; } catch ( WebException webException ) { httpWebResponse = webException. Response as HttpWebResponse; if ( httpWebResponse != null ) { httpStatusCode = ( int ) httpWebResponse. StatusCode ; } } finally { if (httpStatusCode == 200 ) { Console.WriteLine("the resource exists"); } if ( httpWebResponse != null ) { httpWebResponse. Close ( ) ; } } } } Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - using Properties.Settings... to read app.config from windows service application Hi, So just to clarify this: You want to be able to read a value from your XML config file (app.config) and put it in a variable so that you can use it in your application If so, then you're very close already, you just need to use a different class Note that this example is using the app.config file which resides in your application directory (yourApp.exe.config) and I will only show you read only access. If you want to write to an external config file you need to do things slightly differently, as you should *NEVER* write to your applications installation directory, its very bad practice (and thats what the AppData folder is for) Anyway, warning over, this is how to do it: Add a ref to the System.Configuration namespace Code Snippet using System.Configuration; This gives you access to a static class called Configuration Manager. You can use this to grab values out of your configuration file, which is automatically loaded and opened for you. Then you simply extract values, either individually: Code Snippet string strValue = ConfigurationManager.AppSettings["myAttributeName"]; or loop through the whole lot, however you like Code Snippet foreach (string strKey in ConfigurationManager.AppSettings) { string strValue = ConfigurationManager.AppSettings[strKey]; stringBuilder.Add(strKey, strValue); } Hope that helps you If you need to know how to read AND write to an external config file let me know and i'll give you an example Spud/Pete Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - Thread.Abort() Given that a thread has control over the code it is running at the point where it throws the exception, why would it not just exit cleanly instead This is the reason you're unlikely to see any discussion of this scenario. Note that the catch block with the "do nothing" comment is effectively a no-op as ThreadAbortException is special cased and will be raised again once this block exits (unless you intended to do Thread.ResetAbort, in which case throwing the exception itself was effectively a no-op).

    - Concurrency violation while row exists How do you know the database has been updated with the newly added row When you select another row, RowChanged event has been triggered for sure. The adapter.update() method will be called. However, when you still stay in the same row, it's possible the RowChanged event hasn't been triggered.

    - Should webservice return custom entity or dataset (Consider performance) Your web service shouldn't do any formatting at all. Just return the data in a simple, portable manner. Let the consumer create either business entities or datasets, or whatever they like. In particular, a web service can't really return a "classic" business entity, since those have behavior as well as data.

    - .NET and MSMQ Hi Paul, In order to make the things easier for you, you have two options here, WCF ( http://msdn2.microsoft.com/en-us/library/ms789048.aspx ) or a MSMQ custom transport for WSE ( http://www.codeproject.com/useritems/soapmsmq_wse3.asp ) Both options meet your requeriments, altough the first one is more official. You can also use transactional queues, so if an error happens in the service, the message is returned to the queue. Regards, Pablo.

    - Simple question Im sure You need to check where your reader is position by comparing reader.LocalName and reader.NamespaceURI properties to whatever you expect ("ITEM" and "" in your sample). XmlReader would stop on comments () and may be whitespaces. It is not good practice call Read() several times and expect that reader is on correct position.

    - perl or C Efficient can mean many different things and it depends highly on your current programming skills. Did you mean with efficient: - Program code with the least amount of effort - Program code which is as fast as possible Choosing a language where it is possible to get more speed does help nothing if you are not familar with it. Learning Perl is easier to learn than C++ but also more limited to processing text files (parsing, generating statiscs, reports, ...).You could learn quite a lot from Regular Expressions and how they are applied within Perl quite fast.

    - To retrieve EventLogEntry based on the source Not really. Internally the enumerator uses the underlying Win32 API to retrieve the log entries. The API does not allow for filtering. You could however wrap the above code in a simple function to give the illusion of filtering. Clients can then pass the source and log as input and get back only the events that match. You need to be a little careful though as there can be a lot of entries. The class itself pulls the data back when requested rather than caching the entries internally. You should follow a similar approach. Michael Taylor - 5/7/07 http://p3net.mvps.org Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - problem facing in making a phone dialer from .net This seems more like a PBX/Telephony issue than a .NET issue. Are you sure the prefix is #1 it's typically #9 in most PBXs but I guess it's configurable. Also, is it possible you need to have a delay after the #1 waiting for the external dialing tone before you can dial the rest of the number (Something some phones do for you automatically if you just dial the whole number) Tag: .NET Base Class Library Help with the DES functions in Visual C# .NET sdk V2 .NET Development

    - Functions vs Properties, Class vs Structure, Variables vs Properties Very intriguing question! Believe it or not, but the CLR exposes properties as method calls at compile-time . Look it up for yourself... thorugh ILDASM (the IL disassembler). As far as classes and structures go, there is a huge differnece. Classes are reference types while structures are value types. There are numerous articles on this topic... just search for it on the Net. If you are dealing with larger 'objects,' classes would be better, but it is not uncommon to mix the two types in a library/application.

Hasan ACAR

Hello People,

I am a graduate university student who is dealing with implementing a DES algorithm for graduation project, and I wonder if you could spare some information about configuring the basic DES functions without

using System.Security.Cryptography;

kind of prepared classes. The inside of them is actually needed for me for a C# application 
and I am also ready for your offers for the windows form to be used . Please help , thanks a lot.
