• Is there a way to determine gaps in try/catch coverage?

  - by Mike Pateras

  I'm debugging a service that's experiencing some problems on start-up. To aid me in this, I'm wrapping pretty much everything in a try/catch block, and writing any errors to a file. I don't want to put them in every method, I just want to put them in the highest level methods so that they catch exceptions from other methods. Something is getting through, though, as the service does stop under some conditions. Is there a way to determine where the gaps in my try/catch coverage are, other than by sight?

• Performing LINQ Self Join

  - by senfo

  I'm not getting the results I want for a query I'm writing in LINQ using the following: var config = (from ic in repository.Fetch() join oc in repository.Fetch() on ic.Slot equals oc.Slot where ic.Description == "Input" && oc.Description == "Output" select new Config { InputOid = ic.Oid, OutputOid = oc.Oid }).Distinct(); The following SQL returns 53 rows (which is correct), but the above LINQ returns 96 rows: SELECT DISTINCT ic.Oid AS InputOid, oc.Oid AS OutputOid FROM dbo.Config AS ic INNER JOIN dbo.Config AS oc ON ic.Slot = oc.Slot WHERE ic.Description = 'Input' AND oc.Description = 'Output' How would I replicate the above SQL in a LINQ query? Update: I don't think it matters, but I'm working with LINQ to Entities 4.0.

• How to execute a function until it succeeds?

  - by Starx

  I am writing a function to send a mail to specific user? What I am trying to do is, if error occurs I want to keep on sending the mail until the mail is sent. function sendmail() { $name = mysql_escape_string($name); $email = mysql_escape_string($email); $phone = mysql_escape_string($phone); $content = nl2br(mysql_escape_string($content)); $subject = "mail from ".$name." (".$email.", Ph: ".$phone.")"; $mail = @mail($feedback,$subject,$content,$headers); if($mail) { echo "Your mailis send"; } else { echo "We are sorry for the inconvienience, but we could not send your mailnow."; } } the above function displays error message but instead of giving the error, I want to try to send the mail until the mail is finally sent.

• Workaround for UnsupportedAudioFileException ?

  - by tschan

  I'm in a very early stage of writing a small music/rhythm game in Java (via Slick framework, which in turns uses OpenAL, but that's probably irrelevant here). The game needs to read (and playback) several sound files in WAV format, but some of the files are throwing [javax.sound.sampled.UnsupportedAudioFileException] exceptions. at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1102) at org.newdawn.slick.openal.WaveData.create(WaveData.java:123) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:713) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:683) at org.newdawn.slick.Sound.<init>(Sound.java:33) The files can be played back just fine in Winamp or Foobar2000, so this means Java just don't recognize some variants of the file format. What are my options at this point? Note: The files in question are user-supplied, so i cannot just convert them beforehand (using something like audacity). Any conversion steps must be done at runtime.

• JavaScript function that returns result of ajax call

  - by ilkin

  Hi guys. Help needed. Im writing a function that returns result of ajax call but i did not get any results, i guess it's a scope issue, but is there any way to do it? Here is my code: function Favorites() { var links; $.ajax({ type: "GET", url: "/Services/Favorite.svc/Favorites", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", cache: false, success: function(msg) { links = (typeof msg.d) == 'string' ? eval('(' + msg.d + ')') : msg.d; } }); return links; };

• How do you set a cookie to be accessible across the entire domain in Javascript

  - by Tzarkov

  I suppose there should be a way to set a cookie to be accessible from the entire domain nevermind from which directory you are setting the cookie. Say in mypage.com/blue/index.php y set the cookie "colour=blue;" this way: document.cookie = "colour" + "=" + "blue" + "; expires=" + expireDate.toGMTString() + "; path=/"; Using this code, the cookie retrieval function in mypage.com/home.php can't access the content of the cookie. If it was just from first level directories that the cookie needs to be set, we would be ok by doing path=../ instead of path=/ But how do you go about writing generic code that sets a cookie that is accessible from any page in that domain not minding how deep in the file structure is the page the cookie is being set from?

• How can I measure file access performance (and volume) of a (Java) application

  - by stmoebius

  Given an application, how can I measure the amount of data read and written by that application? the time spent reading/writing to disk? The specific application is Java-based (JBoss), and multi-threaded, and running as a service on Windows 7/2008 x64. The overall goal I have is determining whether and why file access is a bottleneck in my application. Therefore, running the application in a defined and repeatable scenario is a given. File access may be local as well as on network shares. Windows performance monitor appears to be too hard to use (unless someone can point me to a helpful explanation). Any ideas?

• Dropdowns don't work on webOS with PhoneGap?

  - by Steve Nay

  I'm trying to use a dropdown in a PhoneGap app I'm writing. It uses a simple <select>: <select> <option value="1">First</option> <option value="2">Second</option> </select> This works fine on Android and the iPhone (including behaving like a native drop-down would on those systems). However, it doesn't appear to work on webOS (neither the Palm Pre itself nor the emulator). The <select> displays properly on the screen, but when I tap on it, nothing happens--I'm not able to make a selection from the dropdown. Why might this be?

• Should every class have its own namespace?

  - by thehouse

  Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does this imply that all classes must have a namespace of their own? If we assume that a class may be augmented in the future by the addition of non-member functions, then it can never be safe to put two types in the same namespace as either one of them may introduce non-member functions that could interfere with the other. The reason I ask is that namespaces are becoming cumbersome for me. I'm writing a header-only library and I find myself using classes names such as project::component::class_name::class_name. Their implementations call helper functions but as these can't be in the same namespace they also have to be fully qualified!

• Set Hibernate session's flush mode in Spring

  - by glaz666

  I am writing integration tests and in one test method I'd like to write some data to DB and then read it. @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:applicationContext.xml"}) @TransactionConfiguration() @Transactional public class SimpleIntegrationTest { @Resource private DummyDAO dummyDAO; /** * Tries to store {@link com.example.server.entity.DummyEntity}. */ @Test public void testPersistTestEntity() { int countBefore = dummyDAO.findAll().size(); DummyEntity dummyEntity = new DummyEntity(); dummyDAO.makePersistent(dummyEntity); //HERE SHOULD COME SESSION.FLUSH() int countAfter = dummyDAO.findAll().size(); assertEquals(countBefore + 1, countAfter); } } As you can see between storing and reading data, the session should be flushed because the default FushMode is AUTO thus no data can be actually stored in DB. Question: Can I some how set FlushMode to ALWAYS in session factory or somewhere else to avoid repeating session.flush() call? All DB calls in DAO goes with HibernateTemplate instance. Thanks in advance.

• How do I rewrite a request by hostname unless it is a specified value?

  - by Tim

  My app will have a regular domain - let's say example.com - which will have information about logging in, signing up, etc. It will also host numerous other domains dynamically. My app serves the webpage for these at http://example.com/site/foobar.com/ So, I need to redirect all requests where the hostname is not example.com to /site/[hostname]/ I'm writing this in Django and hosting with Apache. How do I set up a rewrite rule to do this? The user must not know they are on any other site but foobar.com and if the user browses to foobar.com/something - the URL must be rewritten to /site/foobar.com/something

• Network Communication program in python

  - by lamnep

  Hi all, Basically what I'm trying to achieve is a program which allow users to connect to a each other over a network in, essentially, a chat room. What I'm currently struggling with is writing the code so that the users can connect to each other without knowing the IP-address of the computer that the other users are using or knowing the IP-address of a server. Does anyone know of a way in which I could simply have all of the users scan the IP range of my network in order to find any active 'room' and then give the user a chance to connect to it? Also, the hope is that there will be no need for a central server to run this from, rather every user will simply be connected to all other user, essentially being the server and client at the same time.

• Concatenating a Text in front of Individual Database Records with Tcl

  - by DFM

  Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

• very simple delegate musing

  - by Ted

  Sometimes the simplest questions make me love C/C++ and C# more and more. Today sitting on the bus musing aout delegates I remembered reading somwhere you don't need to use the new keyword when instaniating a new delegate. For example: public static void SomeMethod(string message) { ... } ... public delegate void TestDelgate(string message); //Define a delegate ........... //create a new instance ..METHOD 1 TestDelgate t = new TestDelgate(SomeMethod); //OR another way to create a new instance ..METHOD 2 TestDelgate t = SomeMethod; //create a new instance ..METHOD 2 So todays questions are What happens under the hood in method 2. Does the compiler expand method 2 into method 1, hence writing TestDelgate t = SomeMethod; is just a shortcut for TestDelgate t = new TestDelgate(SomeMethod);, or is there another reason for the exsitence of method 2 Do you guys think method 1 or method 2 is better for readability (this is a subjective question, but I'd just like to get a unscientific feel of general opinion of stackoverflow :-))

• App.Config file in console application C#

  - by user1240679

  I have a console application in which I want to write the name of a file. Process.Start("blah.bat"); Normally, I would have something like that in windows application by writing the name of the file 'blah.bat' to Settings file in Properties. However, here I didn't find any Settings file and I added an app.config for the same purpose. I am not sure what to write here in app.config, that would lead to me to achieve similar thing as in windows forms. For eg: In windows forms. Process.Start(Properties.Settings.Default.BatchFile); where BatchFile is a string in settings file in Properties.

• PHP export to text file - Only saving first line.

  - by wertz8090

  I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

• Customer provider Password Reset client.

  - by ProfK

  I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

• GEvent.addListener(...) return?

  - by user354436

  Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

• Can the dirtiness of pages of a mmap be found from userspace?

  - by chrisdew

  Can dirtiness of pages of a (non-shared) mmap be accessed from userspace under linux 2.6.30+? Platform-specific hacks and kludges welcome. Ideally, I'm looking for an array of bits, one per page (4kB?) of the mmap'ed region, which are set if that page has been written to since the region was mmap'ed. (I am aware, that the process doing the writing could keep track of this information - but it seems silly to do so if the kernel is doing it anyway.) Thanks, Chris.

• Is there a way to cause a new C++ class instance to fail, if certain conditions in the contructor ar

  - by Jim Fell

  As I understand it, when a new class is instantiated in C++, a pointer to the new class is returned, or NULL, if there is insufficient memory. I am writing a class that initializes a linked list in the constructor. If there is an error while initializing the list, I would like the class instantiator to return NULL. For example: MyClass * pRags = new MyClass; If the linked list in the MyClass constructor fails to initialize properly, I would like pRags to equal NULL. I know that I can use flags and additional checks to do this, but I would like to avoid that, if possible. Does anyone know of a way to do this? Thanks.

• Android Dropdown (Select) CSS

  - by roguepixel

  I'm currently writing some stylesheets for mobile browsers and have come across a strange issue in the Android browser. When changing the font-size CSS attribute of a text box the box gets bigger to accomodate the larger text. Doing this on a select box however does not change the size of the select box, but the text still gets larger (actually overlapping the top and bottom of the rendered form element). Can anyone tell me if it's possible to increase the height of select boxes in the Android browser. Or if not point me in the direction of a list of CSS attributes that can be applied to them. Thanks.

• I'd like to preview a Word document on form.

  - by Tychumsempir

  I'm writing a VB program that fills in values within a word document. I'm utilizing the Microsoft Word 12.0 Object Library as a Reference. I'd like to provide a scrollable preview pane to my user that is within the form he or she is using. It would be even cooler if the user could edit the document through this pane. I've done Interop extensively, so I'm well aware of how to write and edit a Word document. I just want to put it into a frame and preview it. I'll probably try to select around the document based on what is changing as the user provides input so they can see what's being changed and where. Thoughts? Thanks

• Open generic interface types of open implementation don't equal interface type?

  - by George Mauer

  Here's a test that should, in my opinion be passing but is not. [TestMethod] public void can_get_open_generic_interface_off_of_implementor() { typeof(OpenGenericWithOpenService<>).GetInterfaces().First() .ShouldEqual(typeof(IGenericService<>)); } public interface IGenericService<T> { } public class OpenGenericWithOpenService<T> : IGenericService<T> { } Why does this not pass? Given Type t = typeof(OpenGenericWithOpenService<>) how do I get typeof(IGenericService<)? I'm generally curious, but if you're wondering what I'm doing, I'm writing a Structuremap convention that forwards all interfaces implemented by a class to the implementation (as a singleton).

• node.js storing gamestate, how?

  - by expressnoob

  I'm writing a game in javascript, and to prevent cheating, i'm having the game be played on the server (it's a board game like a more complicated checkers). Since the game is fairly complex, I need to store the gamestate in order to validate client actions. Is it possible to store the gamestate in memory? Is that smart? Should I do that? If so, how? I don't know how that would work. I can also store in redis. And that sort of thing is pretty familiar to me and requires no explanation. But if I do store in redis, the problem is that on every single move, the game would need to get the data from redis and interpret and parse that data in order to recreate the gamestate from scratch. But since moves happen very frequently this seems very stupid to me. What should I do?
