If the windows application is on the same PC as the service best is to use .NET Remoting with IPC protocol. Registering a IPC port will not make the firewall jump and you can use binary serialization.

In VS.NET 2005 right click a .cs file and chose "View Class Diagram".

You have to make 2 different Application Pools(App1 and App2), set the ASP.NET 1.1 sites to run on the App1 pool and ASP.NET 2.0 on the App2 pool.

I am hosting in a windows service a remoting object as singleton, I want to make sure that clients calls are thread-safe. Here is the class definition: [Synchronization(true)] public class Service : MarshalByRefObject, IService My question to you is if the Synchronization attribute is a good thing or should I use locks inside every Method of the Service class.

In VS.NET go to Debugger menu and select the 'Attach process', you'll be able to debug the service.

Here is my code, I've test it with BMP but I think it will work with any image format. using System.IO; using System.Drawing; using System.Runtime.Serialization.Formatters.Soap; Image image = Image.FromFile(file); // load some image SoapFormatter formater = new SoapFormatter(); byte[] obj; using (MemoryStream ms = new MemoryStream()) { formater.Serialize(ms, image); obj = ms.ToArray(); } string str = Convert.ToBase64String(obj); // convert byte[] to string byte[] bytes = Convert.FromBase64String(str);// convert string to byte[] Image newImage; using (MemoryStream ms = new MemoryStream(bytes)) { newImage = (Image)formater.Deserialize(ms); } newImage.Save(file + ".bmp");

Did you write code to load the data or you've drag/drooped in VS.NET a connection/dataset and so on?

http://stefanprodan.wordpress.com

That's easy, just use AppDomain.CurrentDomain.BaseDirectory to get the running directory and add to it your console application name and you have a path just like Application.ExecutablePath.

Look at the BitConverter class, BitConverter.ToString Method (Byte[]).

Get ProcessExplorer or a similar tool and monitor the asp.net process that is running your webservice, I think that IIS is restarting the process due to large amount of RAM usage. I got the same error uploading large files by calling a webservice, chunk by chunk. A solution is to use free the memory from time to time by calling the Garbage Collector.

Thread.BeginCriticalRegion does not block the abort command, and by the way the first rule that I've learned about multi-threading is to never use Abort, there are tones of other ways to stop a thread gracefully. Here it is an alternative to Thread.Abort: http://stefanprodan.wordpress.com/2007/03/22/stop-threads-gracefuly[^]

This is not a strange behavior, your should start a new thread to do the time consuming work and on the finish event of the tread set the btnGo.Text = "Start".

You can make a static class that exposes properties that you can set/get from different threads. So when your activated event fires the thread will get the value of the property. Because you are using a multi-threading application the static properties should use lock {...} inside the get/set.

heavy load of optimization = ANSI C :)

Well here it is a function that i use to encode strings in XML files: /// /// Convert To Base64 /// /// clean text /// 1(Unicode) 2(ASCII) 3(UTF7) 4(UTF8) /// Base64 string public static string ToB64(string text, Int16 type) { string rez = null; switch (type) { case 1: //Unicode rez = Convert.ToBase64String(Encoding.Unicode.GetBytes(text)); break; case 2: //ASCII rez = Convert.ToBase64String(Encoding.ASCII.GetBytes(text)); break; ase 3: //UTF7 rez = Convert.ToBase64String(Encoding.UTF7.GetBytes(text)); break; case 4: //UTF8 rez = Convert.ToBase64String(Encoding.UTF8.GetBytes(text)); break; } eturn rez; } and to decode: /// /// Convert From Base64 /// /// encrypted text /// 1(Unicode) 2(ASCII) 3(UTF7) 4(UTF8) /// clean text public static string FromB64(string text, Int16 type) { string rez = null; switch (type) { case 1: //Unicode rez = Encoding.Unicode.GetString(Convert.FromBase64String(text)); break; case 2: //ASCII rez = Encoding.ASCII.GetString(Convert.FromBase64String(text)); break; case 3: //UTF7 rez = Encoding.UTF7.GetString(Convert.FromBase64String(text)); break; case 4: //UTF8 rez = Encoding.UTF8.GetString(Convert.FromBase64String(text)); break; } return rez; }

I gues you need a Zip like utility. There is a free zip lib made in C# here icsharpcode.net

You can do it in .NET really easy. All you need to do is a Web Service, the site will call a method on that web service and pass the data, and then the web service will insert into Oracle.

I need this feature for a LAN application, I can provide to the user an interface with IP, Mask, Gateway and DNS configuration but not the MAC, so if anyone tryed this in C# please let me know.

Anyone knows how to change the MAC of the first Network adapter using C#? Thanks
