  • Where is the JTree definition for eclipse's Project Explorer?

    - by Jim
    Hello, The JTree implementation / Renderer used in eclipse (see the navigation pane on the left side) is extremely good. I've checked out the eclipse source code and am looking through it, but can't seem to find the reference to the JTree used. Does anyone know which package contains the definition of this pane? Thanks!

  • MX Records - go to two servers?

    - by Jim Beam
    Right now I have a single mail server for IMAP. Let's say I want to introduce Exchange but not all users will be on it. Some users will be on my "legacy" IMAP, others on the "new" Exchange. Is it possible to "split up" your users (from the same e-mail domain) on two services like this? What would the MX records look like? My guess is that this isn't possible, but thought I'd ask. By the way, I realize that Exchange can offer IMAP and all that, but my question is more about splitting users across services and the MX records. The actual protocols above are only examples.

  • Is there a way to programatically popup the "Microsoft Silverlight Configuration" dialog?

    - by Jim McCurdy
    I am building for Silverlight 4, and I handle MouseRightButtonDown events and build my own ContextMenu's (a class from the Silverlight Toolkit). I would like to add the classic "Silverlight" menu item to my menus, and give the user the familiar option of launching the "Microsoft Silverlight Configuration" dialog. This is the dialog lets users manage Updates, Webcams, Permissions, and Application Storage. So I need a way to programatically launch the dialog when the menu item is clicked. I can be done for Flash, and it would seem that Microsoft would want to encourage developers to support that option. Can it be done?

  • Creating a property setter delegate

    - by Jim C
    I have created methods for converting a property lambda to a delegate: public static Delegate MakeGetter<T>(Expression<Func<T>> propertyLambda) { var result = Expression.Lambda(propertyLambda.Body).Compile(); return result; } public static Delegate MakeSetter<T>(Expression<Action<T>> propertyLambda) { var result = Expression.Lambda(propertyLambda.Body).Compile(); return result; } These work: Delegate getter = MakeGetter(() => SomeClass.SomeProperty); object o = getter.DynamicInvoke(); Delegate getter = MakeGetter(() => someObject.SomeProperty); object o = getter.DynamicInvoke(); but these won't compile: Delegate setter = MakeSetter(() => SomeClass.SomeProperty); setter.DynamicInvoke(new object[]{propValue}); Delegate setter = MakeSetter(() => someObject.SomeProperty); setter.DynamicInvoke(new object[]{propValue}); The MakeSetter lines fail with "The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly." Is what I'm trying to do possible? Thanks in advance.

  • Ninject problem binding to constant value in MVC3 with a RavenDB session

    - by Jim
    I've seen a lot of different ways of configuring Ninject with ASP.NET MVC, but the implementation seems to change slightly with each release of the MVC framework. I'm trying to inject a RavenDB session into my repository. Here is what I have that's almost working. public class MvcApplication : NinjectHttpApplication { ... protected override void OnApplicationStarted() { base.OnApplicationStarted(); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); } protected override IKernel CreateKernel() { return new StandardKernel(new MyNinjectModule()); } public static IDocumentSession CurrentSession { get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; } } ... } public class MyNinjectModule : NinjectModule { public override void Load() { Bind<IUserRepository>().To<UserRepository>(); Bind<IDocumentSession>().ToConstant(MvcApplication.CurrentSession); } } When it tries to resolve IDocumentSession, I get the following error. Error activating IDocumentSession using binding from IDocumentSession to constant value Provider returned null. Activation path: 3) Injection of dependency IDocumentSession into parameter documentSession of constructor of type UserRepository Any ideas on how to make the IDocumentSession resolve?

  • xerces serialization in Java 6

    - by Jim Garrison
    In Java 6, the entire xerces XML parser/serializer implementation is now in the Java runtime (rt.jar). The packages have been moved under the com.sun.* namespace, which places them off-limits for explicit reference within client code. This is not a problem when using the parser, which is instantiated via javax API-defined factories. However, our code also uses xerces serialization (org.apache.xml.serialize.* ). AFAICT, there are no javax.xml API-defined factories for creating instances of Serializer and OutputFormat. This seems to imply that the only way to get one is to explicitly call the com.sun.org.apache.xml.serialize.* APIs. I've found the serialization classes in javax.xml.stream, but they don't seem to provide any output-formatting control like the xerces OutputFormat class. Question: Is there a way to access the xerces serialization functionality (which is in rt.jar) via a javax standard API, without including xerces.jar and also without explicitly instantiating com.sun.* classes? If not, is there an javax API-compliant way to achieve the same effect?

  • MVC 4 Beta with Mobile Project FIle Upload does not work

    - by Jim Shaffer
    I am playing around with the new MVC 4 beta release. I created a new web project using the Mobile Application template. I simply added a controller and a view to upload a file, but the file is always null in the action result. Is this a bug, or am I doing something wrong? Controller Code: using System.IO; using System.Web; using System.Web.Mvc; namespace MobileWebExample.Controllers { public class FileUploadController : Controller { public ActionResult Index() { return View(); } [AllowAnonymous] [HttpPost] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload(HttpPostedFileBase file) { int i = Request.Files.Count; if (file != null) { if (file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); file.SaveAs(path); } } return RedirectToAction("Index"); } } } And the view looks like this: @{ ViewBag.Title = "Index"; } <h2>Index</h2> <form action="@Url.Action("Upload")" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <input type="submit" value="Submit" /> </form>

  • C# Application Becomes Slow and Unresponsive as String in Multiline Textbox Grows

    - by Jim Fell
    Hello. I have a C# application in which a LOT of information is being added to a Textbox for display to the user. Upon processing of the data, almost immediately, the application becomes very slow and unresponsive. This is how I am currently attempting to handle this: var saLines = textBox1.Lines; var saNewLines = saLines.Skip(50); textBox1.Lines = saNewLines.ToArray(); This code is run from a timer every 100mS. Is there a better way to handle this? I am using Microsoft Visual C# 2008 Express Edition. Thanks.
