  • Are there any MVP Frameworks projects out there?

    - by Greg Malcolm
    MVC is used a number of popular frameworks. To name just a few, Ruby on Rails, ASP.NET MVC, Monorail, Spring MVC. Are there any equivalent frameworks using any variant of MVP? Most of the examples I've found online seem to be custom implementations of the pattern rather than reusable frameworks. Suggestions need not be specific to any particular programming language, my interest is mostly academic.

  • Tomcat 6, two login methods, one war

    - by Ofri Dagan
    Hi, I'm using Tomcat to deploy two web-services endpoints but on one WAR file (I used one WAR because the two endpoint implementations are calling one another). How can I define different login methods to each endpoint? I actually need two different custom realm for each endpoint... Thanks

  • How to keep a local value from being set when a binding fails (so inherited values will propagate)

    - by redoced
    Consider the following scenario: I want to bind the TextElement.FontWeight property to an xml attribute. The xml looks somewhat like this and has arbitrary depth. <text font-weight="bold"> bold text here <inlinetext>more bold text</inlinetext> even more bold text </text> I use hierarchical templating to display the text, no problem there, but having a Setter in the template style like: <Setter Property="TextElement.FontWeight" Value="{Binding XPath=@font-weight}"/> sets the fontweight correctly on the first level, but overwrites the second level with null (as the binding can't find the xpath) which reverts to Fontweight normal. I tried all sorts of things here but nothing quite seems to work. e.g. i used a converter to return UnsetValue, which didn't work. I'm currently trying with: <Setter Property="custom:AttributeInserter.Wrapper" Value="{custom:AttributeInserter Property=TextElement.FontWeight, Binding={Binding XPath=@font-weight}}"/> Codebehind: public static class AttributeInserter { public static AttributeInserterExtension GetWrapper(DependencyObject obj) { return (AttributeInserterExtension)obj.GetValue(WrapperProperty); } public static void SetWrapper(DependencyObject obj, AttributeInserterExtension value) { obj.SetValue(WrapperProperty, value); } // Using a DependencyProperty as the backing store for Wrapper. This enables animation, styling, binding, etc... public static readonly DependencyProperty WrapperProperty = DependencyProperty.RegisterAttached("Wrapper", typeof(AttributeInserterExtension), typeof(AttributeInserter), new UIPropertyMetadata(pcc)); static void pcc(DependencyObject o,DependencyPropertyChangedEventArgs e) { var n=e.NewValue as AttributeInserterExtension; var c = o as FrameworkElement; if (n == null || c==null || n.Property==null || n.Binding==null) return; var bex = c.SetBinding(n.Property, n.Binding); bex.UpdateTarget(); if (bex.Status == BindingStatus.UpdateTargetError) c.ClearValue(n.Property); } } public class AttributeInserterExtension : MarkupExtension { public override object ProvideValue(IServiceProvider serviceProvider) { return this; } public DependencyProperty Property { get; set; } public Binding Binding { get; set; } } which kinda works, but can't track changes of the property Any ideas? Any links? thx for the help

    - by PaN1C_Showt1Me
    Suppose you want to throw Exception like this: 'Project with the provided ID cannot be assigned.' and you don't want to write your custom Exception class. What predefined Exception class would you use for this? (I'm talking about all classes inheriting from Exception)

  • Bluetooth service problem

    - by hara
    hi I need to create a custom bluetooth service and I have to develop it using c++. I read a lot of examples but I didn't success in publishing a new service with a custom UUID. I need to specify a UUID in order to be able to connect to the service from an android app. This is what i wrote: GUID service_UUID = { /* 00000003-0000-1000-8000-00805F9B34FB */ 0x00000003, 0x0000, 0x1000, {0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB} }; SOCKET s, s2; SOCKADDR_BTH sab if (WSAStartup(MAKEWORD(2, 2), &wsd) != 0) return 1; printf("installing a new service\n"); s = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM); if (s == INVALID_SOCKET) { printf ("Socket creation failed, error %d\n", WSAGetLastError()); return 1; } memset (&sab, 0, sizeof(sab)); sab.addressFamily = AF_BTH; sab.port = BT_PORT_ANY; sab.serviceClassId = service_UUID; if (0 != bind(s, (SOCKADDR *) &sab, sizeof(sab))) { printf ("bind() failed with error code %d\n", WSAGetLastError()); closesocket (s); return 1; } int result=sizeof(sab); getsockname(s,(SOCKADDR *) &sab, &result ); printSOCKADDR_BTH(sab); if(listen (s, 5) == 0) printf("listen() is OK! Listening for connection... :)\n"); else printf("listen() failed with error code %d\n", WSAGetLastError()); printf("waiting connection"); for ( ; ; ) { int ilen = sizeof(sab2); s2 = accept (s, (SOCKADDR *)&sab2, &ilen); printf ("accepted"); } if(closesocket(s) == 0) printf("closesocket() pretty fine!\n"); if(WSACleanup () == 0) printf("WSACleanup() is OK!\n"); return 0; When i print the SOCKADDR_BTH structure retrieved with get getsockname i get an UUID that is not the mine. Furthermore if i use the UUID read from getsockname to connect the Android application the connection fails with this exception: java.io.IOException: Service discovery failed Could you help me?? Thanks!

  • looping through variable post vars and adding them to the database

    - by Neil Hickman
    I have been given the task of devising a custom forms manager that has a mysql backend. The problem I have now encountered after setting up all the front end, is how to process a form that is dynamic. For E.G Form one could contain 6 fields all with different name attributes in the input tag. Form two could contain 20 fields all with different name attributes in the input tag. How would i process the forms without using up oodles of resource.

  • TG2.1: Proper location to store a database session instance?

    - by Lee Olayvar
    I am using a custom database (MongoDB) with TG 2.1 and i am wondering where the proper place to store the PyMongo connection/database instances would be? Eg, at the moment they are getting created inside of my inherited instance of AppConfig. Is there a standard location to store this? Would shoving the variables into the project.model.__init__ be the best location, given that under SQLAlchemy, the database seems to commonly be retrieved via: from project.model import DBSession, metadata Anyway, just curious what the best practice is.

  • supress warning for generated c# code

    - by soren.enemaerke
    I have turned on "Treat warnings as errors" for my VS project which mean that I get errors for missing documentation (nice reminder for this particular project). However, part of the code is generated by a custom tool which does not insert xml documentation so I'm looking for away to ignore the missing xml documentation for the generated code only, not for the entire project. I have no influence on the actual file generated and cannot really insert anything in the file (as it is regenerated frequently by the tool) so I looking for something existing outside the generated file (the classes that are generated are partial, if that helps)

  • Recursively find files/directories within a directory

    - by enchilada
    I want to use enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: to do this, as I'm coding under Snow Leopard. I know how to use this method. However, as for my purposes it's not adequate to load the contents lazily, I have the following question: How can I create an object hierarchy (of, say, the custom FileOrDirectory class with the standard children,count,isLeaf attributes) from the information I load from the enumeratorAtURL: method? I need to load this data beforehand, and show it in an outline view, for my purposes.

  • Embedding a Bitmap in ASP.NET's WebResource

    - by Andreas Grech
    I am generating a System.Drawing.Bitmap on the fly in an ASP.NET Custom Web Server Control, and then I want to serve this bitmap as part of the WebResource, because I do not want to save it on the hosting computer. Is there a way to instruct ASP.NET to serve the generated System.Drawing.Bitmap as part of it's WebResource? (therefore making it an "Embedded Resource")

  • Enable debugging in Design mode in VS

    - by Dan Tao
    Is there any way to enable debugging from within the Windows Forms Designer in Visual Studio (any version, up to and including 2010)? What I mean is, say I have some custom user control, and this control has certain validation that it performs when I set a particular property. I'd like to be able to set a breakpoint somewhere within that code, and step through it to see what happens when I set the property from the designer.

  • How to recreate the UITabBarItem image filter?

    - by boliva
    Hi, I'm writing a custom UITabBar replacement, and I would like to know how to recreate the filter that the built-in implementation does with the UITabBarItem image - that blue shining on selected tabs and gray gradient on unselected ones. I guess it's a matter of using the source image alpha value as a mask and overlay it with a pre-made blue (or whatever color) shining image and another one grayed out, but I would like to know what is the best approach from a code point of view. Best,

  • Getting the Assembly Qualified Name of a class in Visual Studio

    - by Alex Marshall
    Hello, I'm writing a customized reflective library for some specialized custom domain logic, and that library is going to use XML configuration files that will dynamically resolve System.Type objects at runtime. However, when writing the XML configuration files, it's a bit of a pain to write the types because they need to be fully qualified assembly names for Type.GetType() to resolve them. Is there a way to find out the AssemblyQualifiedName of an object in Visual Studio without resorting to writing a program to print them out to a file or standard out or anything like that ?
