• Visual Studio 2008 (Pre-release) Bug in ItemsControl?

  Hi there, The ItemsControl seems to have problems with item selection whenever the items in it override Equals(object) such that the behavior is not reference equality. For example, if you a bunch of Int32s to a ListBox and some of the ints have the same value, selection is broken. Here is some XAML to demonstrate the problem: < Window x:Class = " ItemsControlBugRepro.Window1 " xmlns = http://schemas.microsoft.com/winfx/2006/xaml/presentation xmlns:x = http://schemas.microsoft.com/winfx/2006/xaml xmlns:col = " clr-namespace:System.Collections;assembly=mscorlib " xmlns:sys = " clr-namespace:System;assembly=mscorlib " Title = " ItemsControlBugRepro " > < Windo ...Show All

• Visual Studio 2008 (Pre-release) Sending selected tree view item data to model (how to bind)

  Hi All! I am trying to develop simple WPF-based application and faced one problem. I have UserControl that contains TreeView. This tree view is bound to hierarchical Categories structure. User can select one particular category and view the contents of the selected category in some list view (this list view is not from the same UserControl). Now I want to have Application.SelectedCategory property which will always contain the category selected in tree view. This property will be used in other user conrols. I tried to establish OneWayToSource data binding using TreeView.SelectedItem property, but the attempt failed because this property is get-only and it is not registered as dependency property. What should I do Handle selection change ev ...Show All

• SQL Server Report Headers vs Page Headers

  Hi, this is probably a simple question but I just can't figure it out. I'm using SQL Server Reporting Services 2005 sp1. I'm trying to design a report that displays a particular embedded image on the first page, and then a different one on every subsequent page. I.e full, fancy company logo on the first page, and a trimmed down version on every other. In Crystal, I would have simply used the Report Header and Page Header sections to achieve this - easy. However, in SQL Reporting Services, there is only a Page Header section - therefore whatever I place in the Page Header shows on every page. Now, I know how to stop it displaying on the first page, but I don't know how to display the other image instead. I read in a support forum t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Compile in Release

  I am in a huge rush right now. Between VS2003 and VS2005 they moved where you choose whether you compile in Debug or Release mode. Where is it now I have manually added the drop-down box to the tool bar, but it's grayed out. This is extremely frustrating and critical to testing DirectX stuff. Inside the build menu there is only: Build, Rebuild, Clean, and Publish. As for Project Settings, I am guessing you mean Project Properties. And yes, I can access that through the Project menu or right clickong on the project in the Solution Explorer. (And to think that the VS2005 help had a three line article saying: "Select from the Solutions Configuration drop-down box on the standard toolbar& ...Show All

• Visual Studio 2008 (Pre-release) WCF hosting: NT Service X IIS?

  Hi Everybody! We are starting a new project for a high available web system and we are thinking about using WCF to provide the required services. Probably we will use server clusters in order to provide the required availability, but we don't know yet if the solution shall use 3 levels of clustering (web, application/business and database) or 2 (web/application and database) as it depends on the customer budget. I'd like to know which solution would be more suitable: hosting the WCF services as NT Services or within IIS. Could you help me regarding the pros/cons of using each one considering: 1 - How easy each one adapts to the clustering hardware solution 2- Performance 3 - Security ...Show All

• .NET Development Best practice in declare

  What is the best practice for declare any objects I wish to know what diference this make. Like: 1) object obj ; obj - new object(); obj.toString(); 2) new object().toString(); Will use more memory then other What it can help my program Best performance Less memory usage like in example 2, this will be deleted after i use Point well taken, if you have an object that has file handles or other critical resources, then you should explicitly dispose of the object so the object's resource properly returned.

• Software Development for Windows Vista Hosting WorkflowService (WorkflowRuntime) in IIS using WCF

  Hi, I'd like to host some kind workflow service (using Windows Workflow Foundation) within the IIS. Therefore I have configured a service file (.svc) and an appropriate web.config file. When the service starts (managed by IIS ) it should load the WorkflowRuntime instance. Therefore I've created a class implementing the IExtension<ServiceHostBase> interface holding that instance. Because my application is not directly responsible for creating the ServiceHost (-> IIS) - how can I add this extension to the service host Is it possible to configure this via the web.config file (<extensions>-Element) Or do I have to write such a class inheriting from ServiceHostFactoryBase and configuring the service file Thank you! ...Show All
