  • 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 to adjust microphone gain from C# (needs to work on XP & W7)...

    - by Ed
    First, note that I know there are a few questions like this already posted; however they don't seem to address the problem adequately. I have a C# application, with all the pInvoke hooks to talk to the waveXXX API, and I'm able to do capture and play back of audio with that. I'm also able to adjust speaker (WaveOut) volume with that API. The problem is that for whatever reason, that API does not allow me to adjust microphone (WaveIn) volume. So, I managed to find some mixer code that I've also pulled in and access through pInvoke and that allows me to adjust microphone volume, but only on my W7 PC. The mixer code I started with comes from here: http://social.msdn.microsoft.com/Forums/en-US/isvvba/thread/05dc2d35-1d45-4837-8e16-562ee919da85 and it works, but is written to adjust speaker volume. I added the SetMicVolume method shown here... public static void SetMicVolume(int mxid, int percentage) { bool rc; int mixer, vVolume; MIXERCONTROL volCtrl = new MIXERCONTROL(); int currentVol; mixerOpen(out mixer, mxid, 0, 0, MIXER_OBJECTF_WAVEIN); int type = MIXERCONTROL_CONTROLTYPE_VOLUME; rc = GetVolumeControl(mixer, MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE, type, out volCtrl, out currentVol); if (rc == false) { mixerClose(mixer); mixerOpen(out mixer, 0, 0, 0, 0); rc = GetVolumeControl(mixer, MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE, type, out volCtrl, out currentVol); if (rc == false) throw new Exception("SetMicVolume/GetVolumeControl() failed"); } vVolume = ((int)((float)(volCtrl.lMaximum - volCtrl.lMinimum) / 100.0F) * percentage); rc = SetVolumeControl(mixer, volCtrl, vVolume); if (rc == false) throw new Exception("SetMicVolume/SetVolumeControl() failed"); mixerClose(mixer); } Note the "second attempt" to call GetVolumeControl(). This is done because on XP, in the first call to GetVolumeControl (refer to site above for that code), the call to mixerGetLineControlsA() fails with XP systems returning MIXERR_INVALCONTROL. Then, with this second attempt using mixerOpen(out mixer, 0, 0, 0, 0), the code doesn't return a failure but the mic gain is unaffected. Note, as I said above, this works on W7 (the second attempt is never executed because it doesn't fail using mixerOpen(out mixer, mxid, 0, 0, MIXER_OBJECTF_WAVEIN)). I admit to not having a good grasp on the mixer API, so that's what I'm looking into now; however if anyone has a clue why this would work on W7, but not XP, I'd sure like to hear it. Meanwhile, if I figure it out before I get a response, I'll post my own answer...

  • Can gems be used by ruby code compiled with macrubyc

    - by sal
    MacRuby 0.5 includes a ruby compiler built on LLVM called macrubyc. Does anyone know if it would be possible to dynamically load gems from compiled code? Or compile the gems and link them in? Is this planned? Or how compiled code will be able to make use of gems in general.

  • 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()); } } }

  • C - How to implement Set data structure?

    - by psihodelia
    Is there any tricky way to implement a set data structure (a collection of unique values) in C? All elements in a set will be of the same type and there is a huge RAM memory. As I know, for integers it can be done really fast'N'easy using value-indexed arrays. But I'd like to have a very general Set data type. And it would be nice if a set could include itself.

  • Exploring the Factory Design Pattern

    - by asksuperuser
    There was an article here: http://msdn.microsoft.com/en-us/library/Ee817667%28pandp.10%29.aspx The first part of tut implemented this pattern with abstract classes. The second part shows an example with Interface class. But nothing in this article discusses why this pattern would rather use abstract or interface. So what explanation (advantages of one over the other) would you give ? Not in general but for this precise pattern.

  • REST verbs - which convention is "correct"

    - by ctacke
    I'm well into implementing a REST service (on a Windows CE platform if that matters) and I started out using IBM's general definitions of using POST for creating (INSERTs) and PUT for updating. Now I've run across Sun's definitions which are exactly the opposite. So my question is, which is the "generally accepted" definition? Or is there even one?

  • Is there a way to specify wildcarded region names when using ehcache with hibernate?

    - by bkent314
    When using Ehcache with Hibernate, is there a way to specify region names with wildcards in the ehcache.xml file? For example, to allow for cache settings at the package level (with * as a wildcard indicator): <cache name="com.example.my.package1.*" ... /> <cache name="com.example.my.package2.*" ... /> (Note: The package-level distinction is just an example. My question is to wildcards in the general case.)

  • 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?
