  • How can I connect to MSMQ over a workgroup?

    - by cyclotis04
    I'm writing a simple console client-server app using MSMQ. I'm attempting to run it over the workgroup we have set up. They run just fine when run on the same computer, but I can't get them to connect over the network. I've tried adding Direct=, OS:, and a bunch of combinations of other prefaces, but I'm running out of ideas, and obviously don't know the right way to do it. My queue's don't have GUIDs, which is also slightly confusing. Whenever I attempt to connect to a remote machine, I get an invalid queue name message. What do I have to do to make this work? Server: class Program { static string _queue = @"\Private$\qim"; static MessageQueue _mq; static readonly object _mqLock = new object(); static void Main(string[] args) { _queue = Dns.GetHostName() + _queue; lock (_mqLock) { if (!MessageQueue.Exists(_queue)) _mq = MessageQueue.Create(_queue); else _mq = new MessageQueue(_queue); } Console.Write("Starting server at {0}:\n\n", _mq.Path); _mq.Formatter = new BinaryMessageFormatter(); _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); while (Console.ReadKey().Key != ConsoleKey.Escape) { } _mq.Close(); } static void OnReceive(IAsyncResult result) { Message msg; lock (_mqLock) { try { msg = _mq.EndReceive(result); Console.Write(msg.Body); } catch (Exception ex) { Console.Write("\n" + ex.Message + "\n"); } } _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); } } Client: class Program { static MessageQueue _mq; static void Main(string[] args) { string queue; while (_mq == null) { Console.Write("Enter the queue name:\n"); queue = Console.ReadLine(); //queue += @"\Private$\qim"; try { if (MessageQueue.Exists(queue)) _mq = new MessageQueue(queue); } catch (Exception ex) { Console.Write("\n" + ex.Message + "\n"); _mq = null; } } Console.Write("Connected. Begin typing.\n\n"); _mq.Formatter = new BinaryMessageFormatter(); ConsoleKeyInfo key = new ConsoleKeyInfo(); while (key.Key != ConsoleKey.Escape) { key = Console.ReadKey(); _mq.Send(key.KeyChar.ToString()); } } }

  • Why is hosted storage so expensive?

    - by Mark Henderson
    There are many questions on Server Fault asking why server storage is so expensive. e.g. Why do I have to pay 50 bucks a month per extra gigabyte of storage or Our file server is always running out of space, why doesn't our sysadmin just throw an extra 1TB drive in there? These questions usually come from people who lack an understanding of how enterprise-level storage works and what influences the price. This question is designed to be the "question to end all questions" regarding the price of enterprise storage.

  • Visual Studio reports that not all code path return a value, even though they do

    - by chris12892
    I have an API in NETMF C# that I am writing that includes a function to send an HTTP request. For those who are familiar with NETMF, this is a heavily modified version of the "webClient" example, which a simple application that demonstrates how to submit an HTTP request, and recive a response. In the sample, it simply prints the response and returns void,. In my version, however, I need it to return the HTTP response. For some reason, Visual Studio reports that not all code paths return a value, even though, as far as I can tell, they do. Here is my code... /// <summary> /// This is a modified webClient /// </summary> /// <param name="url"></param> private string httpRequest(string url) { // Create an HTTP Web request. HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest; // Set request.KeepAlive to use a persistent connection. request.KeepAlive = true; // Get a response from the server. WebResponse resp = request.GetResponse(); // Get the network response stream to read the page data. if (resp != null) { Stream respStream = resp.GetResponseStream(); string page = ""; byte[] byteData = new byte[4096]; char[] charData = new char[4096]; int bytesRead = 0; Decoder UTF8decoder = System.Text.Encoding.UTF8.GetDecoder(); int totalBytes = 0; // allow 5 seconds for reading the stream respStream.ReadTimeout = 5000; // If we know the content length, read exactly that amount of // data; otherwise, read until there is nothing left to read. if (resp.ContentLength != -1) { for (int dataRem = (int)resp.ContentLength; dataRem > 0; ) { Thread.Sleep(500); bytesRead = respStream.Read(byteData, 0, byteData.Length); if (bytesRead == 0) throw new Exception("Data laes than expected"); dataRem -= bytesRead; // Convert from bytes to chars, and add to the page // string. int byteUsed, charUsed; bool completed = false; totalBytes += bytesRead; UTF8decoder.Convert(byteData, 0, bytesRead, charData, 0, bytesRead, true, out byteUsed, out charUsed, out completed); page = page + new String(charData, 0, charUsed); } page = new String(System.Text.Encoding.UTF8.GetChars(byteData)); } else throw new Exception("No content-Length reported"); // Close the response stream. For Keep-Alive streams, the // stream will remain open and will be pushed into the unused // stream list. resp.Close(); return page; } } Any ideas? Thanks...

  • How can I see if apache is overloaded and dropping or not accepting connections?

    - by cat pants
    Basically I just want to see if apache is handling a current level of high traffic or if I need to tune it to handle more connections. (I have found plenty of information on the actual tuning, so no help needed there) I know it has been dropping or not accepting connections earlier today, but not seeing anything in the error logs. Is the expected behavior to throw a 503 in the error log if apache cannot accept more connections? If so, what error logging level do I need in order to see these? What is the correct terminology: dropping connections or not accepting connections? MPM is prefork, OS is Linux, apache version is 2.2.15.

  • HP Photosmart C5280 black ink not printing properly

    - by Andreas Strandfelt
    I just got a used HP Photosmart C5280 from my father in law. There is a problem with the black ink, though. Sometimes, it doesn't print and when it does, it's not really black. An example can be seen at the following link, where I created three black boxes on a Word page and printed. The outcome is somewhat blueish: Other tests with black text only come out as blank pages. I have tried using the print head cleaning utility from the menu of the printer as well as doing the cleaning myself with alcohol. Nothing has worked. Any ideas before I throw out the black cartridge?

  • Determine Last Modification Datetime for an Azure Table

    - by embeddedprogrammer
    I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes. My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique: SELECT OBJECT_NAME(OBJECT_ID) as tableName, last_user_update as lastUpdate FROM mydb.sys.dm_db_index_usage_stats This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?

  • How can I set Qmail to relay all mail to one address

    - by MoSiAc
    I'm new to qmail it's setup and working like it should. I need to set it to do something a bit different. I need it to take all mail that would be incoming to it and relay all of that to one address as opposed to whatever address they could have possibly set it to. The idea is we have setup a test enviroment and we want no e-mails from a test server to actually go out to real people so this relay server will catch all of that outgoing mail and throw it into a test e-mail account inbox to check for errors and so forth. I'm honestly not sure if this is even possible so if it's not let me know now so I can come up with a different method to manage all these test e-mails. Thanks

  • Cannot SSH anymore, what went wrong?

    - by lbwtz2
    I use to ssh to a remote server (no rsa-key, just password). Now the server do not accept the connection any more and throw me this error: ssh_exchange_identification: Connection closed by remote host While I can google a little to find a fix I can't figure out what went wrong since I haven't touched anything on the machine since last login. Can you help me find the cause?

  • Unit testing class in a web service in .net

    - by Dan Bailiff
    After some digging here, I took the advice in this thread: http://stackoverflow.com/questions/371961/how-to-unit-test-c-web-service-with-visual-studio-2008 I've created a separate class and my web service class is just a wrapper for that one. The problem is that when I try to create a unit test project in VS2008, it insists on creating a unit test that acts like I'm testing the web service calls instead of the class I specified. I can't get to the class I'm trying to test. I have a web service "subscription_api.asmx". The code behind is "subscription_api.cs" which contains the web method wrapper calls to the real code at "subscription.cs". I would expect to be able to do the following: [TestMethod()] public void GetSystemStatusTest() { subscription sub = new subscription(); XmlNode node = sub.GetSystemStatusTest(); Assert.IsNotNull(node); } But instead I get this mess which is autogenerated from VS'08: /// <summary> ///A test for GetSystemStatus ///</summary> // TODO: Ensure that the UrlToTest attribute specifies a URL to an ASP.NET page (for example, // http://.../Default.aspx). This is necessary for the unit test to be executed on the web server, // whether you are testing a page, web service, or a WCF service. [TestMethod()] [HostType("ASP.NET")] [AspNetDevelopmentServerHost("C:\\CVSROOT\\rnr\\pro\\product\\wms\\ss\\subscription_api", "/subscription_api")] [UrlToTest("http://localhost/subscription_api")] public void GetSystemStatusTest() { subscription_Accessor target = new subscription_Accessor(); // TODO: Initialize to an appropriate value XmlNode expected = null; // TODO: Initialize to an appropriate value XmlNode actual; actual = target.GetSystemStatus(); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } Additionally, there is a "subscription_api.accessor" in the Test References folder. When I try this: [TestMethod()] public void GetSystemStatusTest2() { subscription_Accessor sub = new subscription_Accessor(); XmlNode node = sub.GetSystemStatus(); Assert.IsNotNull(node); } I get an error: Test method subscription_api.Test.subscriptionTest.GetSystemStatusTest2 threw exception: System.TypeInitializationException: The type initializer for 'subscription_Accessor' threw an exception. ---> System.ArgumentNullException: Value cannot be null. I'm really new to unit testing and feel lost. How can I create a unit test just for my subscription class in "subscription.cs" without testing the web service? Am I limited to testing within the same project (I hope not)? Do I have to put the target class in its own project outside of the web service project?

Any way to prove that the card is OK? Thanks

For instance, if I take the difference between 20100511 and 20100428 I would like the result to be 13 and not 83. I know I need to convert the integer fields into date formats but everything I have tried either throws an exception or doesn't work correctly. What am I missing? Answers in vb.net please

    Whenever I try to go to an RSS feed in IE7 directly, I get a very strange error. IE 7 tries to download the page, but fails. It throws an error, Internet Explorer cannot download rss.php from www.example.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. But when I click a link to view the same feed, it doesn't throw an error but displays the XML instead. Are there any ways I caan fix this, that don't involve OS hacks? Also, if I try to put an xsl stylesheet on it, it tries to download the file no matter what and still errors.
