    - RSA : Encrypt with private key and decrypt with public key If you want to protect against generation of licences by someone else, you ought to be signing, not encrypting. Encryption prevents against reading of data by third parties, and signing prevents against writing of data by third parties. If you encrypt with your private key, you won't be protecting against reading of your data by third parties since there's no reason to believe that your intended public key recipients won't share (intentionally or otherwise) the key with anyone else.

    - Culture and DatePattern Hi, I need to format a string using the month and year codes. But is has to be culture aware. Unfortunately the default YearMonthPattern of DateTimeFormatInfo doesn't do the trick because it displays the months in full text. So I tried to provide a custom pattern, but then it isn't culture aware anymore. Dim d As New Globalization.DateTimeFormatInfo d.DateSeparator = "/" d.YearMonthPattern = "MM/yy" Console.WriteLine(dDate.ToString(d.YearMonthPattern, New Globalization.CultureInfo("en-US"))) Console.WriteLine(dDate.ToString(d.YearMonthPattern, New Globalization.CultureInfo("fr-BE"))) Does anybody have an idea how to solve this Thanks, Jan Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - TypeDescriptor.GetProperties () : Interface Issue I think we all would agree that the following code is valid. IBar bar = object as IBar; int i = bar.Foo; I do not have to cast to an IFoo to have the property available and Intellisense is smart enough to show the property on the interface. Why am I wrong to expect the property to show up when using the TypeDescriptor Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - System.Runtime.Remoting.RemotingException: Cannot load type ... Hi I am trying to call a Window Service written in 1.1, through 2.0 code, using remoting, and serviceController class. But i am getting the error, Error System.Runtime.Remoting.RemotingException: Cannot load type BServiceReporter... Source "mscorlib" when I try to call the method GetBWorkerStatusList . oReporter = ( BServiceReporter ) Activator .GetObject( typeof ( BServiceReporter ), sTcpAddr); m_xBatchWorkersStatusList = oReporter.GetBWorkerStatusList(); The lines work, if the ServiceController class uses, WindowService, written in framework 2.0 (But we have to use older windows service; business requirements) I also looked at the following article, which i suspected, and installed the patch, but i think the problem is different http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=300062&SiteID=1 Any help in this, will be highly appreciated thanks in advance Jan Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - Passing a Stream to a Web Service Do take in consideration that you're not using a Webservice anymore (simply add a new Item -> Generic Item to your webproject)... Code Snippet public class MyStreamHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { Stream yourStream = null; // the stream you want to send context.Response.ContentType = "application/octet-stream"; StreamHelper.Copy(yourStream, context.Response.OutputStream, 1024); } public bool IsReusable { get { return true; } } } And now implement a client to consume: Code Snippet static void Main(string[] args) { Stream yourStream = null; // the stream you have to receive... WebRequest req = WebRequest.Create("http://example.com/StreamHandler.ashx"); WebResponse rsp = req.GetResponse(); using (Stream input = rsp.GetResponseStream()) using (Stream output = yourStream)) { StreamHelper.Copy(input, output, 1024 * 1000); } } Console.Write("{0}Press any key to continue…", Environment.NewLine); Console.ReadKey(); } And if you were wondering, the StreamHelper class StreamHelper { public static void Copy(Stream input, Stream output, int bufferSize) { byte[] buffer = new byte[bufferSize]; int bytesRead; while ((bytesRead = input.Read(buffer, 0, bufferSize)) > 0) { output.Write(buffer, 0, bytesRead); } } } Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - Why isn't my object garbage collected ? Thanks for your efforts, but your answers are not very useful. Why am I calling GC.Collect() Just read the documentation of GC.WaitForPendingFinalizers() (and the example) and you'll see that it's supposed to do something. I should never depend on GC to free unmanaged memory I never expected nor wrote that. The fact is that my control relies on native libraries and thereby holds unmanaged memory. Tracking unmanaged memory leaks would be much easier if I could ensure at some point that all the managed objects no longer referenced have actually been finalized (so that my managed objects can free their native resources). I posted the boring bit All I want to understand is why the garbage collector does not collect objects that only show WeakLns, and WeakShs. That's all. I'll be happy with a link to an URL that will help me understand this. Chris. Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - thread.abort causes "error 2" Hi, I have a application that ataches to an Excel file (using jet 4) and fills a dataset in a background thread. This background thread uses calls a specific dll to handle the connection to the Excel file. If the user clicks 'Cancel' from the main form then the main thread calls thread.abort followed by thread.join. However, just after thread.abort is called a messagebox pops up saying "Error 2" - no other text or title is displayed in the messagebox. I have no idea what is causing this error - i have tried catching the threadabortexception but the messagebox pops up before this exception is caught. I am really stumped by this...any help would be really appreciated. Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - Access memory error after unmanaged interop in Vista. This makes no sense. The CLR cannot possibly free the pointer, it doesn't have to reside in any heap at all or might point into the middle of an allocated block. I'm pretty sure it won't try. It is clear we are not looking at the actual code, it is missing a double-quote. Nevertheless, it allocates insufficient bytes to store the string and anything can happen after it executes, including an AccessViolation. The way this code is written would be questionable even if only a native client would use it. The function signature should be int GetStringFromUnmanage(char* buffer, int buflen) so that the client can pass the function a buffer that it then fills with the string. You would pass an initialized StringBuilder at the managed side: StringBuilder sb = new StringBuilder(1024); GetStringFromUnmanage(sb, sb.Capacity); string retval = sb.ToString(); ... [DllImport(...)] private static extern int GetStringFromUnmanage(StringBuilder buffer, int buflen); Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - prefix for the default namespace Unfortunately this doesn't work. The code above with the example from my second post gets only the one record tag that has the xmlns defined on the tag itself. Aslong as there is no namespace in the root element everything else is ignored. What is the difference with this (extremely easy) solution XmlNodeList list = resultPage.GetElementsByTagName("record"); Do I have a big performance penalty Thanks!

    - Problem connecting to sql server express edition I have difficulties connecting to my SQL Server Express edition. The Server and its SQL Browser are both running and named pipes are enabled, even if I am not sure why it would return such an error since I only try to connect to my localhost. My connection string is currently: Data Source=localhost\SQLEXPRESS;Integrated Security=True;Pooling=False the initial catalog is not yet set, because I try to use the connection (System.Data.SqlClient.SQLConnection) to create a new database by ddl. The resulting error is: provider: Named Pipes-Provider, error: 40 Connection to SQL-Server could not be established Any suggestion greatly appreciated.

    - How do I serialize a Bitmap class? 1. The serialization of Bitmap directly will not give you the serialized data of actual bitmap because BitMap object will not have it with it. Its similar like FileInfo that FileInfo is information about File but not actual file in it, you need to use FileStream to get the content and same way BitMap is information about the image but not having actual content so you will need to somehow save the content in stream and then you need to serialize that stream for which i have given above an example 2. If you want to do that using your custom serializer then also internally you will need to do the same thing 3. In your custom serializer, Serialize method will not be called because it has different parameters and its protected. Please have a look at the following link. This thread is not relavant to you but it has the code which may help you under "Re: Config Load Time" heading written by Piotr. He shown code for custom xml serializer from Enterprise lib somewhere. http://www.theserverside.net/news/thread.tss thread_id=31518 HTH, Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - FTP GetFileSize Confusing Problem I am in the process of writing an FTP client in .NET 2.0. During the testing of getFileSize, I have come across a strange and confusing error. I have a test directory of over 200+ files that I was testing this on, and for every file in this directory this method worked fine EXCEPT on files with an exact size of 17227 bytes. When I call this method on a file of this size I get the WebException with the message of: "The remote server returned an error: 213 1722_" Well, as you can see the 213 File Status response is fine except that the last '7' in the size is now a '_' ..... Let me say again, this method worked on every file in the test directory except files of size 17227 bytes. WTF Any ideas anyone public long getFileSize( string remoteFilePath) { long fileSize = 0; try { //Set connection properties ftpRequest = (FtpWebRequest)FtpWebRequest.Create( new Uri(remoteFilePath)); ftpRequest.Credentials = new NetworkCredential(userName, password); ftpRequest.UseBinary = useBinary; ftpRequest.UsePassive = usePassive; ftpRequest.KeepAlive = keepAlive; ftpRequest.Proxy = null ; //Set command ftpRequest.Method = WebRequestMethods.Ftp.GetFileSize; FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse(); Stream ftpStream = response.GetResponseStream(); fileSize = response.ContentLength; ftpStream.Close(); response.Close(); } catch { throw ; } return fileSize; } Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

    - Excessive garbage collection in .net 1.1 I think it could be a memory fragmentation problem, which means having memory that is empty but not usable. You say that you are creating a lot of objects for many clients and keeping them around. This can easily cause a memory framgentation problem if these objects are always in use (such as response buffers in case of asp.net) as the garbage collector cannot move objects which are in use by clients, specially when used for a long time due to slow connection. A similar problem with asp.net response buffer is desribed here . If you have any tool that can test memory fragmentation then you can use it to see if this assumption is true. I have three ideas: 1-Why are you using a weak reference for the cache why don't you use an ordinary reference to prevent the garbage collector from deleting the cache 2-Can you find a time where you gurantee there are no request on your applications or there are no objects in use by clients if so, you can call GC.Collect() to free the memory and defragment it in this idle time, so it will not cause delayed response for the users. Doing this defragmentation periodically there will be no reason for the garbage collector to trigger insanly. 3-Can you configure your application to use .NET framework 2.0 to make sure it is not a bug that was already fixed in .NET framework 1.1 Tag: .NET Framework Networking and Communication How to Start Building a firewall in c# .net .NET Development

Re: .NET Framework Networking and Communication How to Start Building a firewall in c# .net

Mike Danes

You cannot build a firewall using C# and .NET. A firewall needs to run inside the operating system network stack and the only available option to do this is creating a kernel mode driver using Windows Driver Developer Kit and the C language (or eventually C++ language if you really know what you are doing).

Re: .NET Framework Networking and Communication How to Start Building a firewall in c# .net

Mike Flasko

Your best bet will be to look into developing a Layered Service Provider (see the Winsock reference page in MSDN). This always you to build a firewall-like component in user space.

For even more control, look into the Windows Filtering Platform that will be available in Kernel space in Longhorn. See microsoft.com for more information.

I'd recommend doing it in a lower-level language like C using Windows SDK or VC++ or MFC. C# or .net is not a good choice simply because it can be disassembled easily. For a critical app like firewall, its not the best choice.
