  • Django unique_together error and validation

    - by zubinmehta
    class Votes(models.Model): field1 = models.ForeignKey(Blah1) field2 = models.ForeignKey(Blah2) class Meta: unique_together = (("field1","field2"),) I am using this code as one of my models. Now i wanted to know two things: 1. It doesn't show any error and it saved an entry which wasn't unique together; So is the piece of code correct? 2. How can the unique_together constraint be be validated?

  • Python Permutation Program Flow help

    - by dsaccount1
    Hello world, i found this code at activestate, it takes a string and prints permutations of the string. I understand that its a recursive function but i dont really understand how it works, it'd be great if someone could walk me through the program flow, thanks a bunch! <pre><code> import sys def printList(alist, blist=[]): if not len(alist): print ''.join(blist) for i in range(len(alist)): blist.append(alist.pop(i)) printList(alist, blist) alist.insert(i, blist.pop()) if name == 'main': k='love' if len(sys.argv)1: k = sys.argv[1] printList(list(k))

  • StyleCop SA1124 DoNotUseRegions is reasonable?

    - by Yanhua
    SA1124 DoNotUseRegions suggest that region should not be used anywhere. Is it really reasonable? I think region is a way to group relative code together and make large class easy to read, for example, if you generate interface method in for class, a region will be automatically inserted by visual studio. I would like to remove this rule while checking code style. May I know your ideal on this rule?

  • integer Max value constants in SQL Server T-SQL?

    - by AaronLS
    Are there any constants in T-SQL like there are in some other languages that provide the max and min values ranges of data types such as int? I have a code table where each row has an upper and lower range column, and I need an entry that represents a range where the upper range is the maximum value an int can hold(sort of like a hackish infinity). I would prefer not to hard code it and instead use something like SET UpperRange = int.Max

  • Setting the datasource of a WPF Grid

    - by Ben
    Hi, I'm very new to WPF, and am trying to set the datasource (which the WPF Grid doesn't have as a property) of my grid to take a List. Does anyone have any code examples of how to do this. I have googled it, but can't find any really good examples. (Oh, and can anyone suggest a good site for all round WPF Code examples?) Thanks

    - by yak
    Im working now on simple gui appllication in Java/C++ and CORBA. I want my client on VirtualBox connect to server on localhost. When I have a simple app, like a calc I wrote about earlier its just fine. But when it comes to run client which needs some args witch javas -cp option, Im getting errors. (Theres no such problem when I have both client and server in localhost!) My errors: WARNING: "IOP00100007: (BAD_PARAM) string_to_object conversion failed due to bad scheme name" org.omg.CORBA.BAD_PARAM: vmcid: OMG minor code: 7 completed: No at com.sun.corba.se.impl.logging.OMGSystemException.soBadSchemeName(Unkn own Source) at com.sun.corba.se.impl.logging.OMGSystemException.soBadSchemeName(Unkn own Source) at com.sun.corba.se.impl.resolver.INSURLOperationImpl.operate(Unknown So urce) at com.sun.corba.se.impl.resolver.ORBInitRefResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.orb.ORBImpl.resolve_initial_references(Unknown Source) at ClientConnection.connect(ClientConnection.java:57) at Client.main(Client.java:295) Exception in thread "main" org.omg.CORBA.BAD_PARAM: vmcid: OMG minor code: 7 completed: No at com.sun.corba.se.impl.logging.OMGSystemException.soBadSchemeName(Unkn own Source) at com.sun.corba.se.impl.logging.OMGSystemException.soBadSchemeName(Unkn own Source) at com.sun.corba.se.impl.resolver.INSURLOperationImpl.operate(Unknown So urce) at com.sun.corba.se.impl.resolver.ORBInitRefResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.orb.ORBImpl.resolve_initial_references(Unknown Source) at ClientConnection.connect(ClientConnection.java:57) at Client.main(Client.java:295) make[1]: *** [run] Error 1 ClientConnection.java:57 is a line objRef = clientORB.resolve_initial_references("NameService"); Client.java:295 is a line: ClientConnection.connect(args); A connect method is just an ordinary client-connection corba code.

Whats wrong? I mean, a simple code works fine but gui version doesnt want to ... is there a problem with -cp option? I cant change my apps' dir tree.

  • Using Server.CreateObject("ADODB.Stream") in IE7

    - by Daud
    I have a asp.net 1.1 application that uses the following code to write out a file in the response: Dim objStream As Object objStream = Server.CreateObject("ADODB.Stream") objStream.open() objStream.type = 1 objStream.loadfromfile(localfile) Response.BinaryWrite(objStream.read) This code is called by a pop up window that displays this file or gives a open/save dialog in Internet explorer. The problem is, that it seems to work fine in IE6 but in IE7 the pop up opens and then closes without displaying the file. Any one know whats wrong?

  • Class Problem (c++ and prolog)

    - by Joshua Green
    I am using the C++ interface to Prolog (the classes and methods of SWI-cpp.h). For working out a simple backtracking that john likes mary and emma and sara: likes(john, mary). likes(john, emma). likes(john, ashley). I can just do: { PlFrame fr; PlTermv av(2); av[0] = PlCompound("john"); PlQuery q("likes", av); while (q.next_solution()) { cout << (char*)av[1] << endl; } } This works in a separate code, so the syntax is correct. But I am also trying to get this simple backtracking to work within a class: class UserTaskProlog { public: UserTaskProlog(ArRobot* r); ~UserTaskProlog(); protected: int cycles; char* argv[1]; ArRobot* robot; void logTask(); }; This class works fine, with my cycles variable incrementing every robot cycle. However, when I run my main code, I get an Unhandled Exception error message: UserTaskProlog::UserTaskProlog(ArRobot* r) : robotTaskFunc(this, &UserTaskProlog::logTask) { cycles = 0; PlEngine e(argv[0]); PlCall("consult('myFile.pl')"); robot->addSensorInterpTask("UserTaskProlog", 50, &robotTaskFunc); } UserTaskProlog::~UserTaskProlog() { robot->remSensorInterpTask(&robotTaskFunc); // Do I need a destructor here for pl? } void UserTaskProlog::logTask() { cycles++; cout << cycles; { PlFrame fr; PlTermv av(2); av[0] = PlCompound("john"); PlQuery q("likes", av); while (q.next_solution()) { cout << (char*)av[1] << endl; } } } I have my opening and closing brackets for PlFrame. I have my frame, my query, etc... The exact same code that backtracks and prints out mary and emma and sara. What am I missing here that I get an error message? Here is what I think the code should do: I expect mary and emma and sara to be printed out once, every time cycles increments. However, it opens SWI-cpp.h file automatically and points to class PlFrame. What is it trying to tell me? I don't see anything wrong with my PlFrame class declaration. Thanks,

  • How quickly toggle smart quotes in Word 2010?

    - by KnowItAllWannabe
    I'm working on a long technical document that contains numerous displays of computer code. In running text, I want my quotation marks to be curly, which means that Word's "smart quotes" autoformatting-as-I-type feature is one I want on. But in code displays, curly quotes are incorrect, so in these cases, I want smart-quotes-as-I-type disabled. Is there a fast way to toggle this setting? Or is there a way I can tie it to the paragraph style I'm in? (I use a distinct style for code displays.) Currently, to toggle the setting, I have to click FileOptionsProofingAutoCorrect Options..."Straight quotes" with "smart quotes"OKOK, which is seven mouse clicks. Toggling it back is another seven mouse clicks. Isn't there a faster way? A keyhboard shortcut to do the toggling or a toolbar button that would toggle it with a single click would be great. Having the setting depend on the paragraph style I was in would be even better.

    Hi, I've read the article http://davidhayden.com/blog/dave/archive/2009/05/19/ASPNETMVCAjaxBeginForm.aspx and now I have small problem with that code: <%using (Ajax.BeginForm("ChangeData", new AjaxOptions { UpdateTargetId = "myLabel" })) { %> <input id="mbutton" type="submit" value="blabla" /> <%} %> <label id="myLabel"></label> then, in the MyBookController.cs is the code to be invoked asynchronous: public ActionResult ChangeData() { return Content("OK"); } but, it doesn't work asynchronously, the compiler doesn't go inside that method

  • NHibernate Transactions Best Practices

    - by Ramiro
    I have been reading about Nhibernate for a while and have been trying to use it for a site I'm implementing. I read the article by Billy McCafferty on NHibernate best practices but I did not see any indication on where is the best place to handle transactions. I thought of putting that code in the Data Access Object (DAO) but then I'm not sure how to handle cases in which more than one DAO is used. What are the best places to put transaction code in your NHibernate Application?

  • .NET Sockets and Proxy Servers

    - by Tristan
    I'm trying to make some source code for a library I downloaded work with a proxy server. The library uses sockets to connect to a server but if the client using the library is behind a proxy server it can't connect. Does anyone know how I can modify the socket to be able to connect to the server through a proxy server? I really want to just do this with the sockets in the library without having to change too much code to use WebRequest or something similar

  • Is Ogre's use of Exceptions a good way of using them?

    - by identitycrisisuk
    I've managed to get through my C++ game programming career so far virtually never touching exceptions but recently I've been working on a project with the Ogre engine and I'm trying to learn properly. I've found a lot of good questions and answers here on the general usage of C++ exceptions but I'd like to get some outside opinions from here on whether Ogre's usage is good and how best to work with them. To start with, quoting from Ogre's documentation of it's own Exception class: OGRE never uses return values to indicate errors. Instead, if an error occurs, an exception is thrown, and this is the object that encapsulates the detail of the problem. The application using OGRE should always ensure that the exceptions are caught, so all OGRE engine functions should occur within a try{} catch(Ogre::Exception& e) {} block. Really? Every single Ogre function could throw an exception and be wrapped in a try/catch block? At present this is handled in our usage of it by a try/catch in main that will show a message box with the exception description before exiting. This can be a bit awkward for debugging though as you don't get a stack trace, just the function that threw the error - more important is the function from our code that called the Ogre function. If it was an assert in Ogre code then it would go straight to the code in the debugger and I'd be able to find out what's going on much easier - I don't know if I'm missing something that would allow me to debug exceptions already? I'm starting to add a few more try/catch blocks in our code now, generally thinking about whether it matters if the Ogre function throws an exception. If it's something that will stop everything working then let the main try/catch handle it and exit the program. If it's not of great importance then catch it just after the function call and let the program continue. One recent example of this was building up a vector of the vertex/fragment program parameters for materials applied to an entity - if a material didn't have any parameters then it would throw an exception, which I caught and then ignored as it didn't need to add to my list of parameters. Does this seem like a reasonable way of dealing with things? Any specific advice for working with Ogre is much appreciated.

  • Structure of NAnt build scripts and solution structure on build server

    - by llykke
    We're in the process of streamlining/automating build, integration and unit testing as well as deployment. Our software is developed in Visual Studio where we have use both C# and VB.NET in our projects. A single project can be contained within multiple solutions (i.e. Utils project is used in both ProductA and ProductB solutions) For historical reasons our code repository isn't as well structured as one could have hoped for. E.g. Utils project might be located under ProductA solution (because that's were it was first used) but it was later deemed useful for productB development and merely just included into the solution of productB (but still located in a subdirectory of productA). I would like to use continous integration testing and have setup a CC.NET build server where I intend to use NAnt for creating the actual builds. Question 1: How should I structure my builds on the buildserver? Should I instruct CC.NET to retrieve all the projects for productB into a single library e.g. a file structure similar to -ProductB --Utils --BetterUtils --Data or should I opt for a filestructure similar to this -ProductA --Utils -ProductB --BetterUtils --Data and then just have the NAnt build scripts handle the references? Our references in VS doesn't match the actual location in the code repository so it's not possible today to just check-out productB solution and build it straight away (unfortunately). I hope this question makes sense? Question 2: Is it better to check out all the source code located in different projects into a single file folder (whilst retaining some kind of structure) and then build every thing at once or have multiple projects in CC.NET and then let the CC.NET server handle dependencies? Example: Should I have a seperate project in CC.NET for monitoring the automated build/test of Utils project when it's never released on it's own? Or should I just build/test it whilst building it as part of ProductB? I hope the above makes sense and that you can provide me with some arguments for using either option. We're nowhere near an ideal source code repository structure and I would prefer if I can resolve the lack of repository structure on the build server instead of having to clean up the structure of our repository. Switching away from VSS is (unfortunately) not an option. Right now our build consists of either deploying via VS clickonce or pressing F5 so just getting the build automated would be a huge step up for us. Thanks

  • How can I execute a non-blocking System.Beep()?

    - by Siracuse
    In C# I can perform a Console.Beep(). However, if you specify a duration of say 1000, or 1 second, it will not execute the next line of code until that second passes. Is there any way possible to execute Console.Beep() in a non-blocking fashion so it will continue to beep and still continue executing the code below it while beeping?
