  • Retrieving accessors in IronRuby

    - by rsteckly
    I'm trying to figure out how to retrieve the value stored in the Person class. The problem is just that after I define an instance of the Person class, I don't know how to retrieve it within the IronRuby code because the instance name is in the .NET part. /*class Person attr_accessor :name def initialize(strname) self.name=strname end end*/ //We start the DLR, in this case starting the Ruby version ScriptEngine engine = IronRuby.Ruby.CreateEngine(); ScriptScope scope = engine.ExecuteFile("c:\\Users\\ron\\RubymineProjects\\untitled\\person.rb"); //We get the class type object person = engine.Runtime.Globals.GetVariable("Person"); //We create an instance object marcy = engine.Operations.CreateInstance(person, "marcy");

  • C++: How to build an events / messaging system without void pointers?

    - by Jarx
    I'd like to have a dynamic messaging system in my C++ project, one where there is a fixed list of existing events, events can be triggered anywhere during runtime, and where you can subscribe callback functions to certain events. There should be an option for arguments passed around in those events. For example, one event might not need any arguments (EVENT_EXIT), and some may need multiple ones (EVENT_PLAYER_CHAT: Player object pointer, String with message) The first option for making this possible is allowing to pass a void pointer as argument to the event manager when triggering an event, and receiving it in the callback function. Although: I was told that void pointers are unsafe and I shouldn't use them. How can I keep (semi) dynamic argument types and counts for my events whilst not using void pointers?

  • Are all languages used within .net Equally performant?

    - by WeNeedAnswers
    I know the "Sales pitch" answer is yes to this question, but is it technically true. The Common Language Runtime (CLR) is designed as an intermediate language based on Imperative Programming (IP), but this has obvious implications when dealing with Declarative Programming (DP). So how efficient is a language based on a different paradigm than the Imperative Style when implemented in the CLR? I also get the feeling that the step to DP would incur an extra level of abstraction that might not model at all performant, would this be a fair comment? I have done some simple tests using F# and it all looks great, but am I missing something if the programs get more complex?

  • Storing links to internal content pages in ASP.NET MVC

    - by mare
    I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?

  • Is it possible to replace groovy method for existing object?

    - by Jean Barmash
    The following code tried to replace an existing method in a Groovy class: class A { void abc() { println "original" } } x= new A() x.abc() A.metaClass.abc={-> println "new" } x.abc() A.metaClass.methods.findAll{it.name=="abc"}.each { println "Method $it"} new A().abc() And it results in the following output: original original Method org.codehaus.groovy.runtime.metaclass.ClosureMetaMethod@103074e[name: abc params: [] returns: class java.lang.Object owner: class A] Method public void A.abc() new Does this mean that when modify the metaclass by setting it to closure, it doesn't really replace it but just adds another method it can call, thus resulting in metaclass having two methods? Is it possible to truly replace the method so the second line of output prints "new"? When trying to figure it out, I found that DelegatingMetaClass might help - is that the most Groovy way to do this?

  • Get all window handles for a process

    - by Jeremy
    Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

  • Estimate serialization size of objects?

    - by Stefan K.
    In my thesis, I woud like to enhance messaging in a cluster. It's important to log runtime information about how big a message is (should I prefer processing local or remote). I could just find frameoworks about estimating the object memory size based on java instrumentation. I've tested classmexer, which didn't come close to the serialization size and sourceforge SizeOf. In a small testcase, SizeOf was around 10% wrong and 10x faster than serialization. (Still transient breaks the estimation completely and since e.g. ArrayList is transient but is serialized as an Array, it's not easy to patch SizeOf. But I could live with that) On the other hand, 10x faster with 10% error doesn't seem very good. Any ideas how I could do better?

  • Run WF 4.0 as a server-side component

    - by user184216
    Hi all, For a new project, we need to use WF 4.0 for deploying and running workflows. Instead of hosting workflows within the application itself, we decided to implement a server-side component that is in charge of running workflows. Before WF 4.0, one had explicit access to the the runtime engine (WorkflowRuntime), which provided some basic management functionalities, such as retrieving the workflows currently running etc ... As far as I could find out, WF 4.0 lacks this explicit access, as workflows are created via the WorkflowInstance class and no reference is immediately available to the WorkflowRuntime ... If I need these management functionalities on the server side, I'm a correct that I will need to implement these myself? Or did I miss out on something ... Thanks in advance for your answers!

  • Changing content of HTMLDocument displayed in a JTextPane

    - by kayahr
    I'm displaying some tables as HTML code (rendered by a Freemarker template) with a JTextPane. I also have some HTML links in this HTML output which can be used to interact with the values of the table (For example "Delete a row" and stuff like this). Currently I always recreate the whole HTML output on each change and replace the whole document in the JTextPane with the new one. This is getting really slow and the JTextPane always changes the scroll position when I do this. Is it possible to change only parts of the HTML code during runtime without replacing the whole document? In a real browser I would use the DOM and do something like document.getElementById("price").innerHTML = "$123.44". Is something like that possible with the HTMLDocument in a JTextPane?

  • ASP.Net Web Site Project - Errors Not Caught at Compile time

    - by 5arx
    For the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project. I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase. I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime. I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround. Could any StackOverflow person help with suome suggestions to make things better?

  • Cannot Debug Unmanaged Dll from C#

    - by JustSmith
    I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

  • Reading HttpRequest Body in REST WCF

    - by madness800
    Hi All, I got a REST WCF Service running in .net 4 and I've tested the web service it is working and accepting HttpRequest I make to it. But I ran into a problem trying to access the HttpRequest body within the web service. I've tried sending random sizes of data appended on the HttpRequest using both Fiddler and my WinForm app and I can't seem to find any objects in runtime where I can find my request body is located. My initial instinct was to look in the HttpContext.Current.Request.InputStream but the length of that property is 0, so I tried looking in IncomingWebRequestContext that object doesn't even have a method nor properties to get the body of the HttpRequest. So my question is, is there actually a way to access the HttpRequest request body in WCF? PS: The data inside the request body is JSON strings and for response it would return the data inside response body as JSON string too.

  • Setting a value into a object using reflection

    - by marionmaiden
    Hello I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime. For example, what I have is this: public class a{ private typeA attr1; private typeB attr2; public typeA getAttr1(){ return attr1; } public typeB getAttr2(){ return attr2; } public void setAttr1(typeA at){ attr1 = at; } public void setAttr2(typeB at){ attr2 = at; } } public class typeA{ public typeA(){ // doesn't matter } } public class typeB{ public typeB(){ // doesn't matter } } So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this: a test = new a(); a.setAttr1(new typeA()); But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.

  • WPF: change DataTemples according to Value

    - by Kave
    I have a class called Cell with two properties. One is called Value of type int? And the other is called Candidates of type ObservableCollection during the initialization I am utilizing a DataTemplateSelector to choose between two datatemplates for two different scenarios. If the Value property has a value then template A should be used to present the Cell class. However if the Value property is null Then template B should be used to present the Cell class. While this works perfectly fine during the initialization however during the runtime the templates don't change any more when the value of the Value property actually changes. Is the approach of using DataTemplateSelector the wrong approach to change DataTemplates dynamically? What would you recommend I should do? Many thanks,

  • C++ Static array vs. Dynamic array?

    - by user69514
    What is the difference between a static array and a dynamic array in C++? I have to do an assignment for my class and it says not to use static arrays, only dynamic arrays. I've looked in the book and online, but I don't seem to understand. I thought static was created at compile time and dynamic at runtime, but I might be mistaken this with memory allocation. Can you explain to me the difference between static array and dynamic array in C++? Thnaks.

  • Haskell compile time function calculation

    - by egon
    I would like to precalculate values for a function at compile-time. Example (real function is more complex, didn't try compiling): base = 10 mymodulus n = n `mod` base -- or substitute with a function that takes -- too much to compute at runtime printmodules 0 = [mymodulus 0] printmodules z = (mymodulus z):(printmodules (z-1)) main = printmodules 64 I know that mymodulus n will be called only with n < 64 and I would like to precalculate mymodulus for n values of 0..64 at compile time. The reason is that mymodulus would be really expensive and will be reused multiple times.

  • How to effectively copy an array in java ?

    - by Tony
    The toArray method in ArrayList , Bloch uses both System.arraycopy and Arrays.copyOf to copy an array . public <T> T[] toArray(T[] a) { if (a.length < size) // Make a new array of a's runtime type, but my contents: return (T[]) Arrays.copyOf(elementData, size, a.getClass()); System.arraycopy(elementData, 0, a, 0, size); if (a.length > size) a[size] = null; return a; } How to compare these two copy method , when to use which ? Thanks.

  • MS-Access VBA: form_error vs on error

    - by dmr
    I am trying to set up error handling for a MS-Access application. The standard method to do this seems to be with an On Error statement in each subroutine/function. It seems simpler to me to use the Form_Error function to catch all the runtime errors in that form as opposed to an On Error statement for each sub/function called by an event on that form. (Obviously, for code in modules, there is no Form_Error function and therefore the only method is the On Error statement) What are the pros and cons of using On Error vs Form_Error?

  • Form Design ScriptControlClass

    - by raghumithra
    I am working on a form designer. We have two parts: first is designing form by placing controls, and second is writing VB code in rich text editor. How do i integrate design and code (events of the controls) in runtime? I am using ScriptControlClass Form4 f4 = new Form4(); f4.Name = "dgfdfg"; f4.Text = "Raghudfgmithra"; Button btn = new Button(); btn.Text = "HI"; btn.Left = 25; btn.Top = 50; btn.Name = "btnSubmit"; f4.Controls.Add(btn); script.AddObject("form", f4, true); script.AddCode("???????????); script.ExecuteStatement(????????????);

  • Saving Types generated via Reflection.Emit as code file (.cs) instead of saving it in .dll files

    - by Manish Sinha
    Before start let me tell my experience: I am experienced with C#.NET, web services, XML part and few more. Reflection is something new to me, though I have read extensively on it and tried out some experimental code, but haven't made anything great using reflection I checked out many examples of how we can create Type at runtime and then which can be saved in an assembly (.dll) files. Of all the examples I have seen is about saving the created types in the .dll files instead of code file. Isn't there any way to create the code file out of reflection? I need to create code file since I want to distribute code instead of compiled assemblies. What I want to do is something like xsd.exe does, either spit out a .dll or the code file(in any language). Isn't there any way to create a code file, since most of the place I can find is AssemblyBuilder ab = System.AppDomain.CurrentDomain.DefineDynamicAssembly(an, AssemblyBuilderAccess.Save); and then lastly ab.Save("QuoteOfTheDay.dll");

  • C# DLL reference changes version and becomes unloadable (Plugin-system)

    - by Kristoffer
    I will try to keep this as simple as possible. I have a rather simple plugin system that has run into a problem. I have 2 assemblies: Host.exe Plugin.dll Plugin.dll references Host.exe (which contains interfaces and classes that Plugin.dll implement and use). At runtime, Host.exe loads Plugin.dll through reflection and this works great. Except when Host.exe updates and gets a new version number. Then I get an error once I try to load Plugin.dll, saying that Host.exe (with the old version number) can't be found. This means I have to rebuild all plugins every time Host.exe changes build number. Anyone got a solution to this?

  • Problem with filling dataset

    - by Brian
    This is a small portion of my code file. Each time my debugger reaches the line 'NewDA.Fill(NewDS);' at runtime it jumps to the catch. I'm positive the daynumber variable gets a value that's present in the database and I've tried the query outside of the codefile on my database and it works fine. I'm also using the connectionstring 'db' on more parts of the code with successful results. string QueryNew = "SELECT activityname AS [Name], activitycategorynumber AS [Category] " + "FROM ACTIVITY WHERE daynumber = @daynumber"; SqlCommand NewCmd = new SqlCommand(QueryNew, db); NewCmd.Parameters.Add("@daynumber", SqlDbType.Int).Value = daynumber; SqlDataAdapter NewDA = new SqlDataAdapter(NewCmd); DataSet NewDS = new DataSet(); NewDA.Fill(NewDS);

  • License problem embedding Mono?

    - by mydiscogr
    I'd like to embed Mono into an .exe file but the problem is the license, because a LGPL library can only be linked with LGPL code. However, I'd like to build a commercial app, so I ask if is possible to use a stub that launches a DLL version of the Mono runtime and executes my app. Or do you know a better way to do this? I need a cross-platform framework and Mono seems good, but there are some problem to pack it in one file, so you know a "free" way to do this?
