Office 2003: Bring the Power of Visual Studio .NET to Business Solutions Built with Microsoft Office


Microsoft Visual Studio Tools for the Microsoft Office System is a new technology that brings the advanced features of Visual Studio .NET and the .NET Framework to apps built on Microsoft Word 2003 and Excel 2003. Now you can use Visual Basic .NET and C# to write document-centric, managed code solutions that run in-process with Word 2003 or Excel 2003, taking advantage of the rich object models they expose. Along the way you get the benefits of the managed environment in which a fully compiled .NET-based application executes, including code access security.

Visual Basic .NET: New Programming Model and Language Enhancements Boost Development Power


Visual Basic .NET is the result of a significant rebuild of Visual Basic for the Microsoft .NET Framework. There are a number of changes that make Visual Basic .NET easier to use, more powerful than Visual Basic 6.0, and give it the kind of access to system resources that in the past required the use of languages like C++. One of the most important additions is object inheritance. In Visual Basic .NET, all managed types derive from System.Object. An important new language feature is garbage collection, which is administered by the Common Language Runtime and provides better memory management. The universal type system allows for greater interoperability, also contributing to the enhanced power and flexibility found in Visual Basic .NET.

Sharp New Language: C# Offers the Power of C++ and Simplicity of Visual Basic


Many developers wish there was a language that was easy to write, read, and maintain like Visual Basic, but that still provided the power and flexibility of C++. For those developers, the new C# language is here. Microsoft has built C# with type-safety, garbage collection, simplified type declarations, versioning and scalability support, and lots of other features that make developing solutions faster and easier, especially for COM+ and Web Services. This article gives you a first look at C#, a language you are going to be hearing lots more about in the very near future.

SQL query gives results, but Visual Studio doesn't



I have problem accessing data from SQL query in ASP.net. I checked the query and it returns two fields, both with data, but when I run the same query in Visual Studio I get the following error: "Invalid attempt to read data when no data is present."

The problem is that data does exist...

This is what SQL query returns when executed on SQL Server Management Studio (I bolded the different header so you can see the difference):

url idClanak
Upload/Default2.png 8
Upload/Default3.png 8
Upload/Catrinel Menghia 7.jpg 8

The following is the ASP.net code (I bolded the piece of the code that apparently has some problems):

    private void Upisivanje(int idClanak, string naslov, string datumString, string kategorija, string autor, string slika, string opisSlike, string sadrzaj)
        string facebook = "<a href='http://www.facebook.com/sharer.php?u=" + Request.RawUrl + "&t=" + naslov + "'><img src='Images/Facebook.png'/></a>";
        string twitter = "<a href='http://twitter.com/home?status=" + naslov + " na: " + Request.RawUrl + "'><img src='Images/Twitter.png'/></a>

Visual Basic 9.0 error in Visual Studio 2010


I just upgraded from Visual Studio 2005 to Visual Studio 2010 yesterday. I tried opening my site; it started the conversion wizard and seemed to work OK. However, I get the error "Visual Basic 9.0 does not support this kind of lambda expression." Here is my code:

Dim MatchLength As Integer = Url.Path.Length
                        Dim D As GetRedirectedUrlDelegate = _
          Dim NewQuerystring As QuerystringContext = Url.QuerystringContext.Clone()
          Return Url.Clone(NewPath, NewQuerystring)
        End Function

            Match = New RedirectMatch(MatchLength, d)
            Return True

The error is on the "Function()" line. I thought multi-line lambda functions were one of the new VS2010 features. Why am I getting a VB9.0 error

ASP.NET 4 and Visual Studio 2010 Web Development Beta 2 Overview

Many exciting changes for ASP.NET are coming in the .NET Framework version 4. This document gives an overview of many of the new features that are included in the Beta 2 release of the .NET Framework 4 and of Visual Studio 2010.

Visual Studio 2010 Beta 2

This is a big deal. This isn't ".NET 3.6" - there are a lot of improvements of .NET 4, and it's not just "pile on a bunch of features so you get overwhelmed." I've been working with and talking to many of the teams involved and even though it's a cheesy thing to say, this is a really customer-focused release.

ASP 4 - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1

There's a lot of stuff that's new and added in .NET 4, but not in that "overwhelming-I-need-to-relearn-everything" way. More in that, "oh, this is way easier/simpler now" way. Like, moving data around with ADO.NET DataServices is easy, binding with client templates is easy, there's F# if you need it, the "dynamic" keyword if you need it, Silverlight's already installed, oh, and the parallel stuff will freak you out, but in a good way.

Download and Share Visual Studio Color Schemes

The good news is that Visual Studio allows you to completely customize the editor background and text colors to whatever you want - allowing you to tweak them to create the experience that is "just right" for your eyes and personality. You can then optionally export/import your color scheme preferences to an XML file via the Tools->Import and Export Settings menu command.
