• Visual Studio 2008 (Pre-release) Trouble loading Baml using LoadComponent

  Hello, I'm trying to load some baml from resource assemblies using Application.LoadComponent. As a parameter I use Uri that contains full name of assembly with culture: "en". But LoadComponent gives me IOException, that same assembly, but with culture: "neutral", was not found. here is a sample that first loads PresentationFramework Luna baml, and then tries to load mainwindow.baml from Sparkle. Luna baml is loading as expected, but Sparkle baml throws exception: static readonly string PROGRAMFILES= Environment .GetFolderPath( Environment .

• Visual C# What Pattern/approach suits my application requirements.

  Hi all, I have an application scenario that is based on health and safety inspections. So basically, a set of questions and answers. I have a class, Inspections, that contain properties about itself, such as type of inspection, data and time etc, and also a questions and answers collection class to contain both the questions, and answers. Anyway, in my application I need to display these questions (displaying the relevant data controls based on the question types) and gather the answers (which then get written to a database). These set of questions, can be asked against a number of objects (users/buildings - basically whatever a set of quest ...Show All

• SQL Server SQL Reporting Services and SiteMinder (SSO product by Netegrity)

  I have an ASP.NET 2.0 application that displays reports in Reporting Services 2005 using ReportViewer control. Everything works just fine with Windows Authentication. But my client uses a Single Sign On (SSO) product called SiteMinder by Netegrity and not Windows Authentication. Once I integrate my web application with SiteMinder, the web pages work fine but the reports stop rendering and the progress indicators keeps spinning indefinitely. I even tried impersonation (in web config) without any luck. As soon as I remove SiteMinder ISAPI DLL, the reports start rendering using the account I used for impersonation. I am not sure if I coul ...Show All

• .NET Development Performance issue in .NET1.1, WaitForSingleObject hog

  Hi, I have a serious performance issue with some code saving a config to disk, on .NET 1.1, and the performance profiling I have done so far baffles me. Any pointers to relevant information would be much appreciated. In a nutshell: ~90% of the time is spent in kernel code (WaitForSingleObject, WaitForMultipleObjects). See profile snippet below. The bulk seems to originate from numerous thread starts, which I cannot trace further. The active code itself takes only ~7% The code involves JET DB access, plus writing many text files, zipping it all. I have used DevPartner Community Edition for the profiling on .net 1.1 While it has some quirks ...Show All

• .NET Development continue reading byte[]?

  bit of a wierd one here :) I am wondering if it is possible to continue reading/filling a byte[] with data after a previous read I am trying to, delibritly, throw an exception (and handled well at the same time). while ( true ) { int lengthData = this .theNetworkStream.Read(someByte, 0, someByte.Length); //the line above will throw an exception if you read data from a stream which the connection was lost to for some premature reason - this is what i want and can handle it while (this.theNetworkStream.DataAvailable) { lengthData+= this.theNetworkStream.Read(someByte, 0, someByte.Length); } } however as you ...Show All

• SQL Server How to add/(connect to) database in SQL Server 2005 Express?

  Hello, I just downloaded and installed the Visual Web Developer 2005 Express which is part of the new issued Visual Studio 2005 Express. It includes SQL Server 2005 Express, so I also installed it. My problem is I can't connect to the database supported by SQL Server Express. The log in is failed. I hope anyone who is using SQL Server Express can give me a help and tell me what wrong I've done. What I've done are: 1. In the Database Explorer, right-click the Data Connections, I create a new database named "lavender", so it's "lavender.mdf". 2. Then I go to Tools->"connection to database...", (1) then in the pop-up window, I chose the "Dat ...Show All

• Visual Studio Team System TF26198: The work item does not exist, or you do not have permission to access it.

  hi all.  I have been running VSTS at home, but for security ( as in, in case of fire, etc ), I've moved it to my in laws house, put it online using a program called Hamachi, and connected to it over the web.  It all seems to work great.  I can check out code, I can add work items, but when I try to check code in and view the list of work items, I get the error above.  Note: I am logging in as the same user as when the computer was under my desk here, nothing has changed, except the location.  I get the same error when trying to view the list of work items.

• Visual Studio 2008 (Pre-release) Windowless controls for web browser?

  I work for a company that is building a very sophisticated web distributed application that uses a lot of overlapping components.  Most of the app is .asp / thin (meaning it is developed using browser technologies) and that works just fine. However, there are some portions of the app that will require "thicker" technologies to provide the right user experience. I have been struggling to find a way to integrate controls into IE pages such that they play nicely in the browser's z-order.  As i'm sure you are aware, windowed controls do not play nicely in this environment. I need to be able to develop controls that will honor the brows ...Show All

  How do I save a type object to a file and read it in again using c# Of course, like everything in life, that depends.
