Learning .NET Framework 4.0 and Visual Studio 2010 Video Podcast

 

If you are interested in learning on the upcoming .NET Framework 4.0 and Visual Studio 2010, here is an excellent resource for you.

Channel 9 is going to host a weekly podcast on the different capabilities of .NET Framework 4.0 and Visual Studio 2010 at http://channel9.msdn.com/shows/10-4/

While I am currently playing with the VS 2010 and .NET Framework 4.0 build, I am more than keen to tune into these podcasts to hear what others have to say about the new features.

If you aren’t aware, we released the initial bits of VS 2010 and .NET Framework at our Professional Developers Conference http://www.microsoftpdc.com last month and the bits are available now as a VPC Download at http://www.microsoft.com/downloads/details.aspx?FamilyId=922B4655-93D0-4476-BDA4-94CF5F8D4814&displaylang=en

Yes it is a pretty huge download and interestingly, the podcast series is hosting the first podcast on how to get this set up optimally and start using it.

So, tune in to http://channel9.msdn.com/shows/10-4/ and get to know the features of the upcoming VS 2010 and .NET Framework 4.0

Always run WPF App in Maximized View

I have been playing around with WPF Applications and one of the annoying things about WPF as well as Windows Forms is that they always open up in a Normal View (which is like a Restored View) and you have to maximize it to have a full view of your application. I know this is a simple setting right from the VB Days and was wondering where to set it up in case of WPF.

The solution was to just to add the following line of code under the “InitializeComponent()” call in your Window1.xaml.cs or whatever is the startup Window.

      InitializeComponent();

      this.WindowState = WindowState.Maximized;

I am sure there are different ways to achieve this and it can be set at the configuration level etc., But this post is just for simply doing it quickly.  

If there are caveats, best practices, please post in the comments..

Getting Started with ASP.NET

I just had the privilege (trauma?) of setting up my new machine and had to install everything from the scratch.  I will save the rest of my experiences, for another post, but for now I thought of sharing, what I had to install to work with the latest stuff for Web Development in ASP.NET.  These are pretty quick to install and helps you build cutting edge websites.

1. Install Visual Studio 2008 (you can get a trial version from http://msdn.microsoft.com/hi-in/vstudio/products/aa700831.aspx)

or the free Visual Web Developer Expression Edition from http://www.microsoft.com/express/vwd

2. Install .NET 3.5 SP1 and Visual Studio 2008 SP1 from http://www.microsoft.com/downloads/details.aspx?FamilyId=FBEE1648-7106-44A7-9649-6D9F6D58056E&displaylang=en

3. If you installed Visual Studio 2008 and would like to work with ASP.NET 2.0 Applications and use ASP.NET AJAX 1.0 version (multi-targeting in Visual Studio 2008), install the ASP.NET 2.0 AJAX Templates for Visual Studio 2008 http://www.microsoft.com/downloads/details.aspx?FamilyID=5c7df430-1c34-40d2-b6ec-81353b5fcf2e&displaylang=en

4. Install ASP.NET MVC Beta from http://www.microsoft.com/downloads/details.aspx?FamilyId=A24D1E00-CD35-4F66-BAA0-2362BDDE0766&displaylang=en

5. Install Charting controls for Visual Studio from here and here

6. Install the Windows Live Tools for Visual Studio 2008 http://dev.live.com/tools

7. Install the Silverlight essentials from http://silverlight.net/GetStarted

8. Install the Ajax Control Toolkit from http://www.codeplex.com/AjaxControlToolkit/Release/ProjectReleases.aspx?ReleaseId=16488

9. Last but not the least, visit http://www.asp.net/learn for learning resources

Note that steps 3-7 are optional though recommended.  The Silverlight installation contains steps to install Silverlight runtime, Silverlight Tools for Visual Studio (the MediaPlayer control for playing videos)

Hope this saves you from running to different locations.

Cheers !!!

Charting in ASP.NET, ASP.NET Chart Controls for .NET 3.5 SP1

Here is a HelloWorld sample on the new ASP.NET Charting control.

To begin with, install the free Microsoft Chart Controls and the "Tools for VS 2008 for Chart Controls" from here and here

Note that if you don’t install the Tools for VS 2008 for Chart controls, the Chart Server Control doesnt show up in the Toolbox

Once you are done with the installation, restart Visual Studio if you are already running the same (of course, save your work)

1. Start Visual Studio 2008 and create a File – New – ASP.NET Website or a Web Application

2. From the ToolBox, under Data tab, pick up the “Chart” control (the icon would be a series of colored bar graphs) and drag and drop it into the page.

3. Click on the smart tag for configuring the Chart control and Choose DataSource

4. Select “Database” and provide the connection string to your database server (in my case I chose Northwind)

5. Choose to save the connection string etc., and select the Database table (in my case I chose “Category Sales for 1997”)

6. Click “Finish” to complete the process.

7. Now if you run the page you will NOT get the Chart Control.

8. You need to select the Properties of the Chart Control from design view.

9. Make sure under “Data” DataSource is set to “SqlDataSource1” unless you gave a different name and DataMember is set to “DefaultView”

10. Under “Series” in Properties, click on the tab to open up the “Series Collection Editor”.

11. Scroll down the Series1 Properties to DataSource section.

12. Specify “CategoryName” as the XValueMember and “CategorySales” for YValueMembers and click Ok.

13. Build the page and hit F5 to run the page.

14. You will be able to see the Chart in your webpage.

15. Right Click on the chart and you would be able to see that it is an image generated dynamically that can be saved as a “.png” file.

You can download a comprehensive list of samples from here and verify the different implementations and source code for the same.   For more details, visit the forums here

Cheers !!!

Windows Live Tools for Visual Studio 2008
