  • What happens to C# 4 optional parameters when compiling against 3.5?

    - by Bertrand Le Roy
    Here’s a method declaration that uses optional parameters: public Path Copy( Path destination, bool overwrite = false, bool recursive = false) Something you may not know is that Visual Studio 2010 will let you compile this against .NET 3.5, with no error or warning. You may be wondering (as I was) how it does that. Well, it takes the easy and rather obvious way of not trying to be too smart and just ignores the optional parameters. So if you’re compiling against 3.5 from Visual Studio 2010, the above code is equivalent to: public Path Copy( Path destination, bool overwrite, bool recursive) The parameters are not optional (no such thing in C# 3), and no overload gets magically created for you. If you’re building a library that is going to have both 3.5 and 4.0 versions, and you want 3.5 users to have reasonable overloads of your methods, you’ll have to provide those yourself, which means that providing a version with optional parameters for the benefit of 4.0 users is not going to provide that much value, except for the ability to provide named parameters out of order. I guess that’s not so bad… Providing all of the following overloads will compile against both 3.5 and 4.0: public Path Copy(Path destination)public Path Copy(Path destination, bool overwrite)public Path Copy( Path destination, bool overwrite = false, bool recursive = false)

  • Is there any functional difference between immutable value types and immutable reference types?

    - by Kendall Frey
    Value types are types which do not have an identity. When one variable is modified, other instances are not. Using Javascript syntax as an example, here is how a value type works. var foo = { a: 42 }; var bar = foo; bar.a = 0; // foo.a is still 42 Reference types are types which do have an identity. When one variable is modified, other instances are as well. Here is how a reference type works. var foo = { a: 42 }; var bar = foo; bar.a = 0; // foo.a is now 0 Note how the example uses mutatable objects to show the difference. If the objects were immutable, you couldn't do that, so that kind of testing for value/reference types doesn't work. Is there any functional difference between immutable value types and immutable reference types? Is there any algorithm that can tell the difference between a reference type and a value type if they are immutable? Reflection is cheating. I'm wondering this mostly out of curiosity.

  • What are the parameters of APEX destructible asset / actor, and what are the effect of them?

    - by Semih Kekül
    There are parameters of the NxDestructibleAsset such as: defaultBehaviorGroup.damageToRadius destructibleParameters.fractureImpulseScale p3BodyDescTemplate.density structureSettings.useStressSolver destructibleParameters.runtimeFracture.glass.firstSegmentSize, etc. However, i can not find any document explaining these parameters. Are there any documents/videos or codes (anything) which explains these parameters?

  • Java PHP posting using URLConnector, PHP file doesn't seem to receive parameters

    - by Emdiesse
    Hi there, I am trying to post some simple string data to my php script via a java application. My PHP script works fine when I enter the data myself using a web browser (newvector.php?x1=&y1=...) However using my java application the php file does not seem to pick up these parameters, in fact I don't even know if they are sending at all because if I comment out on of the parameters in the java code when I am writing to dta it doesn't actually return, you must enter 6 parameters. newvector.php if(!isset($_GET['x1']) || !isset($_GET['y1']) || !isset($_GET['t1']) || !isset($_GET['x2']) || !isset($_GET['y2']) || !isset($_GET['t2'])){ die("You must include 6 parameters within the URL: x1, y1, t1, x2, y2, t2"); } $x1 = $_GET['x1']; $x2 = $_GET['x2']; $y1 = $_GET['y1']; $y2 = $_GET['y2']; $t1 = $_GET['t1']; $t2 = $_GET['t2']; $insert = " INSERT INTO vectors( x1, x2, y1, y2, t1, t2 ) VALUES ( '$x1', '$x2', '$y1', '$y2', '$t1', '$t2' ) "; if(!mysql_query($insert, $conn)){ die('Error: ' . mysql_error()); } echo "Submitted Data x1=".$x1." y1=".$y1." t1=".$t1." x2=".$x2." y2=".$y2." t2=".$t2; include 'db_disconnect.php'; ?> The java code else if (action.equals("Play")) { for (int i = 0; i < 5; i++) { // data.size() String x1, y1, t1, x2, y2, t2 = ""; String date = "2010-04-03 "; String ms = ".0"; x1 = data.elementAt(i)[1]; y1 = data.elementAt(i)[0]; t1 = date + data.elementAt(i)[2] + ms; x2 = data.elementAt(i)[4]; y2 = data.elementAt(i)[3]; t2 = date + data.elementAt(i)[5] + ms; try { //Create Post String String dta = URLEncoder.encode("x1", "UTF-8") + "=" + URLEncoder.encode(x1, "UTF-8"); dta += "&" + URLEncoder.encode("y1", "UTF-8") + "=" + URLEncoder.encode(y1, "UTF-8"); dta += "&" + URLEncoder.encode("t1", "UTF-8") + "=" + URLEncoder.encode(t1, "UTF-8"); dta += "&" + URLEncoder.encode("x2", "UTF-8") + "=" + URLEncoder.encode(x2, "UTF-8"); dta += "&" + URLEncoder.encode("y2", "UTF-8") + "=" + URLEncoder.encode(y2, "UTF-8"); dta += "&" + URLEncoder.encode("t2", "UTF-8") + "=" + URLEncoder.encode(t2, "UTF-8"); System.out.println(dta); // Send Data To Page URL url = new URL("http://localhost/newvector.php"); URLConnection conn = url.openConnection(); conn.setDoOutput(true); OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()); wr.write(dta); wr.flush(); // Get The Response BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; while ((line = rd.readLine()) != null) { System.out.println(line); //you Can Break The String Down Here } wr.close(); rd.close(); } catch (Exception exc) { System.out.println("Hmmm!!!

  • Clarification needed: How does .NET runtime resolve assembly references from parent folder?

    - by aoven
    I have the following output structure of executables in my solution: %ProgramFiles% | +-[MyAppName] | +-[Client] | | | +-(EXE & several DLL assemblies) | +-[Common] | | | +-[Schema Assemblies] | | | | | +-(several DLL assemblies) | | | +-(several DLL assemblies) | +-[Server] | +-(EXE & several DLL assemblies) Each project in solution references different DLL assemblies, some of which are outputs from other projects in solution, and others are plain 3rd-party assemblies. For example, [Client] EXE might reference an assembly in [Common], which is in a different directory branch. All references have "Copy Local" set to false, to mirror the layout of the files in the final installed application. Now, if I take a look at reference properties in the Visual Studio IDE, I see that "Path" of every reference is absolute and that it corresponds to the actual output location of the assembly. That's understandable and correct. As expected, solution compiles and runs just fine. What I don't understand is, why everything seems to work even when I close the IDE, rename the [MyAppName] directory and run the [Client] EXE manually? How does the runtime find the assemblies if the reference paths aren't the same as they were at the time of linking? To be clear - this is actually exactly what I'm after: a semi-dispersed set of application files that run fine regardless of where the [MyAppName] directory is located or even what it's named. I'd just like to know, how and why this works without any specific path resolution on my part. I've read the answers to this similar question, but I still don't get it. Help much appreciated!

  • How to show "only number" in picture cross-reference in Word 2007 document?

    - by kornelijepetak
    I have many pictures in a document and I reference them very often in text. I don't want to lose the order so I am using Insert - Cross-reference. This opens the cross-reference dialog where I can set Reference type to Picture. For "Insert reference to", there are 5 choices: - Entire caption - Only label and number - Only caption text - Page number - Above/below What I need is a reference that would be inserted like this: [4], and not like this: [Picture 4]; None of these options enable me to do it. Is there any way to make Word 2007 insert a reference to only Caption Number? Note: The document is written in Croatian language which has 7 declension cases, so using "Picture 4" would not be valid in all cases. Actually caption label Picture is set to croatian word "Slika" and when I need to say say "in the picture" I can't because it would be "na Slici 5." and not "na Slika 5." (like Word would make me do). That's why I need to reference only the caption number. Is that possible in Word 2007?

  • SSRS & asp.net - passing parameters from .net to ssrs in report viewer

    - by Ricardo Deano
    Hello all. I am about to embark in using a report viewer in my .net page. I have a page that will search for a catgory, upon a button click, the category chosen will pass into the parameter of report viewer. Now, given that I am a newbie to both SSRS and .net, I'd just like a bit of advice on how to tackle this. Should I make the report in SSRS first and include the parameters in this report or can I make the report without the parameters specified, then programmatically enter this in the codebehind? Basically, I know what I would like to do but not sure the best approach to take. If anyone can offer advice, I would be most grateful.

  • iphone - creating a reference to a MPMoviePlayerController

    - by Mike
    At some point in my code I am creating a MPMoviePlayerController object and playing it. As I need to reference this object at some other methods in my code that runs asynchronously, I need to store a pointer to the movie object etc., so I can use that. Declaring MPMoviePlayerController * myMovie on the header file is out of question, because the compiler will give me an error saying "expected specifier-qualifier-list before 'MPMoviePlayerController'". If it was a view I could do something like [self.view viewWithTag:99]; to get the object, but the MPMoviePlayerController does not allow this. How can I obtain the movie object or store a reference to it, so I can call the object in other methods? thanks for any help.

  • Create a subarray reference in C# (using unsafe ?)

    - by Wam
    Hello there, I'm refactoring a library we currently use, and I'm faced with the following problem. We used to have the following stuff : class Blah { float[][] data; public float[] GetDataReference(int index) { return data[index]; } } For various reasons, I have replaced this jagged array version with a 1 dimensionnal array version, concatenating inner arrays. My question is : how can I still return a reference to a sub array of data ? class Blah { float[] data; int rows; public float[] GetDataReference(int index) { // Return a reference data from offset i to offset j; } } I was thinking that unsafe and pointers stuff may be of use, is it doable ?

  • How to change VS2010 Add Reference box filter ?

    - by rook
    I'm getting used to the new IDE (it's vc# express), but the first contact is somewhat confusing. When I open the Add Reference dialog and switch to the .NET tab, a label above the assembly list states: "Filtered to:.NET Framework 4". And it's true - I can reference .NET 4.0 assemblies only plus things like XNA 3.1. However I can't see older assemblies i.e. Managed DirectX libs, which are obviously installed on my computer as there was no trouble with adding a ref to them in vc#08. What is this? How to change the filter? The label is read-only. These sound like dull guy's questions, but I'm out of lack of finding an answer and there is no intuitive solution. Thanks in advance.

  • Pylons FormEncode @validate decorator pass parameters into re-render action

    - by joelbw
    I am attempting to use the validate decorator in Pylons with FormEncode and I have encountered an issue. I am attempting to validate a form on a controller action that requires parameters, and if the validation fails, the parameters aren't passed back in when the form is re-rendered. Here's an example. def question_set(self, id): c.question_set = meta.Session.query(QuestionSet).filter_by(id=id).first() c.question_subjects = meta.Session.query(QuestionSubject).order_by(QuestionSubject.name).all() return render('/derived/admin/question_set.mako') This is the controller action that contains my form. The form will add questions to an existing question set, which is identified by id. My add question controller action looks like this: @validate(schema=QuestionForm(), form='question_set', post_only=True) def add_question(self): stuff... Now, if the validation fails FormEncode attempts to redisplay the question_set form, but it does not pass the id parameter back in, so the question set form will not render. Is it possible to pass the id back in with the @validate decorator, or do I need to use a different method to achieve what I am attempting to do?

  • WCF method not receiving the parameters

    - by Thiago Sayão
    I have a WCF method that is not receiving the request parameters. But if I use the WCFTest client (the one that comes with visual studio) the method receives the parameters. If I capture the requests, they look very similar: If the request is this, it works: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <consultaValeCompra xmlns="http://tempuri.org/"> <dataMovto>1</dataMovto> <numSeqOperacao>2</numSeqOperacao> <numDocumento>3</numDocumento> <valorDocumento>4</valorDocumento> <tipo>5</tipo> <codPreVenda>6</codPreVenda> </consultaValeCompra> </s:Body> </s:Envelope> If the request is this, I do not get the parameters: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <consultaValeCompra xmlns="http://valeCompra/jaws"> <dataMovto>121212</dataMovto> <numSeqOperacao>003719</numSeqOperacao> <numDocumento>000000000000005555466465454546</numDocumento> <valorDocumento>000046400</valorDocumento> <tipo>0</tipo> <codPreVenda>0000000000</codPreVenda> </consultaValeCompra> </soapenv:Body> </soapenv:Envelope> The method signature is: public Retorno consultaValeCompra(string dataMovto, string numSeqOperacao, string numDocumento, string valorDocumento, string tipo, string codPreVenda) I can spot the differences, but I cannot understand why the first works and the second does not. What can I do to make it work? Thanks.

  • When adding WCF service reference, configuration details are not added to web.config

    - by Mikey Cee
    Hi, I am trying to add a WCF service reference to my web application using VS2010. It seems to add OK, but the web.config is not updated, meaning I get a runtime exception: Could not find default endpoint element that references contract 'CoolService.CoolService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. Obviously, because the service is not defined in my web.config. Steps to reproduce: Right click solution Add New Project ASP.NET Empty Web Application. Right click Service References in the new web app Add Service Reference. Enter address of my service and click Go. My service is visible in the left-hand Services section, and I can see all its operations. Type a namespace for my service. Click OK. The service reference is generated correctly, and I can open the Reference.cs file, and it all looks OK. Open the web.config file. It is still empty! <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <bindings /> <client /> </system.serviceModel> Why is this happening?

  • Foreign key reference to a two-column primary key

    - by Adam Ernst
    One of my tables has a two-column primary key: CREATE TABLE tournament ( state CHAR(2) NOT NULL, year INT NOT NULL, etc..., PRIMARY KEY(state, year) ); I want a reference to the tournament table from another table, but I want this reference to be nullable. Here's how I might do it, imagining that a winner doesn't necessarily have a tournament: CREATE TABLE winner ( name VARCHAR NOT NULL, state CHAR(2) NULL, year INT NULL ); If state is null but year is not, or vice-versa, the table would be inconsistent. I believe the following FOREIGN KEY constraint fixes it: ALTER TABLE winner ADD CONSTRAINT FOREIGN KEY fk (name, state) REFERENCES tournament (name, state); Is this the proper way of enforcing consistency? Is this schema properly normalized?

  • Reference DLLs not loading in Visual Studio 2010

    - by Adam Haile
    I'm working on a C# 4.0 project in VS2010 and needed to use some older DLLs containing controls that were created in C# 3.5 on VS2008. When I first add the DLLs to the references, I was able to see the namespace via intellisense and create an instance of one of the controls, but when I go to build, it gives me the following error: The type or namespace name 'BCA' could not be found (are you missing a using directive or an assembly reference?) And I do have a using directive for that namespace already, which is now underlined in red, showing that VS cannot find it. And now, intellisense won't pick up that namespace at all. I even tried added the controls to the toolbox (which worked) but then when I drag them to the GUI, it says that it cannot locate the DLL reference, even though it obviously knows where it is. I even tried changing the target framework to 3.5, but still with the same results. Any thoughts as to why this could be happening?
