Lap Around Microsoft Web Platform Installer 1.0 aka Web PI

All Web Developers know that while doing design and development, we need lots of Tools and Technology, Also we need to assure and keep track of versions too. From Admin point of view, its pain to install all the new software and maintain versions on each and every machine.

To avoid this pain and to give lot of ease for installing new and updated tools, Microsoft now came ahead with its new unique tool as “Microsoft Web Platform Installer 1.0” , in short it is also known as “WebPI”.

WebPI is basically a UI where it displays you the latest tools available from Microsoft for Web Development, It is very simple so now even Developers and Designers can also go ahead and do installations without having any great knowledge of IIS tools and other add-ins. It basically includes Visual Web Developer 2008 Express Edition, SQL Server 2008 Express Edition and the .NET Framework along with IIS, and not to surprise, it also now listing the current updated tools like Silverlight Toolkit for Visual Studio and ASP.NET MVC. So now all you need is just to install this WebPI tool and your Computer will be ready for Web Development.

You can download WebPI from :

Silverlight 2 : Maintain data in Session using Silverlight-enabled WCF service.

A piece of paper was thrown in front of me on table by my friend in local coffee shop, that paper was nothing but print out of one already designed ASP.NET site which now he want to convert to Silverlight with few of pages as kind of POC for Silverlight. I just saw “Welcome : <Username>” label on that, and I asked him how he is taking care of Sessions in Silverlight? and a puzzle for him..since he never implemented, there are several solutions on net by many people and enthus, here is my piece of code which I feel simple, offcourse you can try that out and help me improve if there any better way to do so.

To show this particular functionality, I am re-using my old code of Master pages in Silverlight since I need more than one page with navigation which you can find it here :

http://pendsevikram.blogspot.com/2008/11/silverlight-2-master-pages.html

Also, if you are not comfortable with Silverlight-enabled WCF services , you can see my old article :

http://pendsevikram.blogspot.com/2008/10/silverlight-2-grid-with-silverlight.html

Step 1 : Create 2 Silverlight Pages

Page.xaml :

<Grid x:Name="LayoutRoot" Background="AliceBlue">
        <TextBlock Height="23" Margin="94,8,116,0" VerticalAlignment="Top" Text="Explore .NET with Vikram Pendse" TextWrapping="Wrap" Foreground="#FF000000"/>
        <StackPanel x:Name="stk" Width="400" Margin="0,66,0,30">
            <TextBlock Margin="78,10,0,30" Text="UserName:"/>
            <TextBox Margin="40,-50,0,30" x:Name="txtuser" Height="20" Width="150" />

<TextBlock Margin="78,-5,25,30">Password :</TextBlock>
            <PasswordBox Margin="40,-60,0,10" x:Name="txtpassword" Height="20" Width="150" />
            <Button x:Name="btnSubmit" Height="20" Width="100" Content="Login" Click="btnSubmit_Click" />
        </StackPanel>
        <TextBlock Height="23" Margin="106,0,104,3" VerticalAlignment="Bottom" Text="Microsoft .NET for everyone!!" TextWrapping="Wrap" Foreground="#FF000000"/>
</Grid>

Welcome.xaml :

<Grid x:Name="LayoutRoot" Background="AliceBlue">
        <StackPanel x:Name="mystk" Width="400" Margin="0,66,0,30">
            <TextBlock Margin="128,-5,0,30" Text="Welcome :"/>
            <TextBlock Margin="196,-46,0,30" x:Name="txtusername" />
        </StackPanel>     
</Grid>

Step 2 : Add a Silverlight-enabled WCF Service and access it in Silverlight application

MyService.svc.cs :

using System.Web;

[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class MyService
    {
        HttpContext myctxt = HttpContext.Current;

        [OperationContract]
        public string Login(string username, string password)
        {
            //Validate Username and Password against the Database.
            myctxt.Session["Uname"] = username;
            return username;
        }

        [OperationContract]
        public string ReturnUser()
        {
            string user;
            user = (string)myctxt.Session["Uname"];
            return user;
        }

Note : For demo purpose, I have not validated User-id and Password against database, please refer comment.

Step 3 : Consume SL-enabled WCF service in each page and pass the corresponding parameters.

First we need to send username and password from Page.xaml.cs to Service, Then Login() will maintain that particular username in session, Then we will again call the service and access that particular username which is in session by ReturnUser()

Page.xaml.cs :

private void NavigateRequest(int w)
{
     if (w > 0)
     {
         stk.Children.Clear(); 
         stk.Children.Add(new Welcome());
      }
      else
      {
          this.Content = new Page();
      }            
}

private void btnSubmit_Click(object sender, RoutedEventArgs e)
{
    Srvc.MyServiceClient proxy = new SL_SessionMgmt.Srvc.MyServiceClient();
    proxy.LoginAsync(txtuser.Text,txtpassword.Password);
    NavigateRequest(1);
}                

Here we are switching among the pages by NavigateRequest(), you can write Switch-case if there are multiple pages.

Welcome.xaml.cs :

public Welcome()
{
    InitializeComponent();
    this.Loaded += new RoutedEventHandler(Welcome_Loaded);
}

void Welcome_Loaded(object sender, RoutedEventArgs e)
{
     Srvc.MyServiceClient proxy = new SL_SessionMgmt.Srvc.MyServiceClient();
     proxy.ReturnUserCompleted += new EventHandler<SL_SessionMgmt.Srvc.ReturnUserCompletedEventArgs>(proxy_ReturnUserCompleted);
     proxy.ReturnUserAsync();
}

void proxy_ReturnUserCompleted(object sender, SL_SessionMgmt.Srvc.ReturnUserCompletedEventArgs e)
{
      txtusername.Text = e.Result;
}

And here we are getting username which is in session by e.Result, This will display the username in session on Textblock on second page, it will look like this.

Here you can see whatever we pass as username, we place it in session by WCF service and get that data from session via service again and bind it to another control on another page.

Hope this will useful for you, if you are planning to implement Sessions in your Silverlight applications.

Microsoft Tag : New way to go Online !!

“Barcode” is something which we come across day to day especially while we do shopping, “RFID” is bit more advance, where you can really track down items within some specific range and process information.

Imagine..A simple small fuzzy and colorful picture full of small triangle of different colors, If I say you just take picture of that on your Windows Mobile phone and once you do that, it will take you here..to my blog..!! Sounds funny..but its not ! This is what Microsoft Tag all about.

As per the information given by Microsoft, Tag works with the fixed-focus camera lenses common in most mobile devices.So you just aim your camera phone at a Tag and instantly access mobile content, videos, music, contact information, maps, social networks, promotions, and more.Nothing to type, no browsers to launch.

Above screen you will get once you visit http://tag.microsoft.com and you can learn more about Tag Technology on http://www.microsoft.com/tag , You will need to sign up there or you can login using Live ID, It is free to log into Tag site.

Once you login, you will find console like I have shown in following screen, you will find a Create Tag Button on Top side of grid, by which you will be thrown to Tag Creation page. On this page you will be able to do all managerial tasks like Edit,Delete,Export and do reporting about the usage of the same.

Once you click on “Create Tag” button,it will allow you to create different types of Tags, something here to make note that, It will ask you to give details according to the “Tag Type” you set.

Once you create Tag successfully and come back to Main window with Grid, you will find a Export option for the Tag you created, it will basically ask you for type and the way to display it, it export it into either pdf,wmf or xps format.

Below is the sample Export in PDF which I took out from the pdf generated by Tag export option.

I hope you will find this new innovation bit of technology interesting and sooner or later you will start using it too. Below is my Tag for my browser, just click snap of it and come here.

Lap around Report Builder 2.0

Report Builder 2.0 is basically used for Designing the Reports which we incorporate in applications using SSRS [SQL Server Reporting Services], You do have one separate template to design and develop Reports using a commonly known tool “SQL Server Business Intelligence Development Studio”. Report Builder 2.0 is independent tool for designing the reports which you can download from :

http://www.microsoft.com/downloads/details.aspx?familyid=9f783224-9871-4eea-b1d5-f3140a253db6&displaylang=en

After installation, you can Run Report Builder 2.0 from Start-> All Programs –> Microsoft SQL Server 2008 Report Builder 2.0

You will then get following Console :

If you observe carefully, Top menu is now got replaced by “Ribbon” [ Refer Top Menu in any MS Office 2007 Application ] which adds ease for finding functionality smoothly and fast since they are categorized.

Left side panel usually contains your Built-in Fields which are provided by default by Report Viewer 2.0, that contains fields like Page numbers, DateTime, Report URL and name and much more.

Middle panel is layout window where you actually place the things like table/matrix/graphs/gauges etc and design report.

Right side panel usually contains properties of respective elements which we have on layout.

If you see the above picture carefully, You will find that now SSRS Report Builder 2.0 enables you to put on Graphs and Gauges on your Report [ Hope you aware of .NET Dundas Control, Now they are here ] , I personally have not seen such wonderful facility of graphs and gauges in crystal reports, even such rich GUI to design reports is not given for the same in Crystal Reports,well I think its totally user choice what to go for.

Inside View Menu you can set and reset Ruler for layout and other windows like Properties and Grouping.

Also do observe on bottom side, same like in MS Office applications, you can now Zoom your layout to a great extend with the zoom scroll given at the bottom side, Also similar to run slides option in PowerPoint at bottom side, now you have Run report option at bottom. This is basically quick way to run reports.

Once you design and develop report, you need to upload the corresponding report files to Report Server Directory on Report Server. For those who are new one, here I am showing you how that window looks like where you can configure your Reporting Server settings. You will find that at Start-> All Programs-> Microsoft SQL Server 2008->Configuration Tools-> Reporting Services Configuration

I hope this will give you overall idea about what is new in Report Builder 2.0, I am not stopping here with this post, I will soon share with you all , how we can actually design report, That I am planning to do with real case base scenario soon which will talk about parameterized reports and graphs also with some Report UI tips and tricks etc.

Silverlight 2 : Using Magnifier to Zoom contents on Canvas

First of all wish all my blog readers very Happy New Year ! , Thanks for your continuous feedback and support all the time. Some people given me feedback in 2008 that I wrote some article too basic and not to the level which they expect, frankly speaking , I wrote here what comes to my mind, what I see and what I feel difficult to understand to others, so I always try my best to keep things simple and quick.But I will do follow your feedback so be with me in year 2009 since lots new on this blog going to be there in coming few months !

There are several post on usage of Magnifier in Silverlight 1.1 as well as in 2.0, Some have done with Images and some with Videos. I am re-making this code snippet which is already published by Jeff Prosise’s blog and code snippet which I am going to share here is already available on one of the PDC 2008 snippet at : http://www.wintellect.com/Downloads/PDC_2008_Demos.zip

Idea of doing this again re-work and twick the already written source code is to create awareness about the Magnifier which can be use efficiently for zooming part of image or video.

Step 1 : Create a Layout which will hold 3 Canvas.

<Grid x:Name="LayoutRoot" Background="Black" MouseLeftButtonDown="OnMouseLeftButtonDown" MouseMove="OnMouseMove" MouseLeftButtonUp="OnMouseLeftButtonUp">

Note that, for Zooming particular portion of Canvas, we are suppose to handle mouse events on all over base canvas which you can see from above events.

<Canvas x:Name="CoreCanvas" Width="800" Height="530">
            <!-- Base canvas -->
            <Canvas x:Name="BaseCanvas" Canvas.Left="0" Canvas.Top="0" Width="800" Height="400" Background="Black">
                <Canvas Canvas.Left="90" Canvas.Top="30" Width="620" Height="470">
                    <Rectangle Canvas.Left="0" Canvas.Top="0" Width="620" Height="470" Fill="White" />
                    <MediaElement Canvas.Left="10" Canvas.Top="10" Width="600" Height="450" Source="Bear.wmv" />
                </Canvas>
            </Canvas>

Above is the Canvas which will hold Video / Image file on which we will put magnifier for zooming.

<!-- Magnify canvas -->
<Canvas x:Name="MagnifyCanvas" Canvas.Left="0" Canvas.Top="0" Width="800" Height="400" Background="Black" Visibility="Collapsed">
                <Canvas.RenderTransform>
                    <ScaleTransform CenterX="0" CenterY="0" ScaleX="4" ScaleY="4"/>
                </Canvas.RenderTransform>
                <Canvas.Clip>
                    <EllipseGeometry x:Name="Lens" Center="0,0" RadiusX="40" RadiusY="40" />
                </Canvas.Clip>
                <Canvas Canvas.Left="90" Canvas.Top="30" Width="620" Height="470">
                    <Rectangle Canvas.Left="0" Canvas.Top="0" Width="620" Height="470" Fill="White" />
                    <MediaElement Canvas.Left="10" Canvas.Top="10" Width="600" Height="450" Source="Bear.wmv" />
                </Canvas>
                <Path Canvas.Left="0" Canvas.Top="0" StrokeThickness="0">
                    <Path.Data>
                         <EllipseGeometry x:Name="LensBorder" Center="0,0" RadiusX="40" RadiusY="40" />
                    </Path.Data>
                </Path>
            </Canvas>
        </Canvas>
      </Grid>

Above code will add another Canvas with Ellipse which is our circular magnifier for zooming, you can try out with RectangleGeometry.

Step 2 : Create a general method as AdjustLens() for maitaining the Magnifier value and position.

Variables declare for drag and scale which keep tracks whether drag by mouse for Magnification or not.

private bool drag = false;
private const double scale = 4.0;

private void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
            double x = e.GetPosition(CoreCanvas).X;
            double y = e.GetPosition(CoreCanvas).Y;
            AdjustLens(x, y);

            MagnifyCanvas.Visibility = Visibility.Visible;
            ((FrameworkElement)sender).CaptureMouse();
            drag = true;
}

OnMouseLeftButtonDown basically pass the position of CoreCanvas to AdjustLens() which keep tracks of all the movements on Canvas.Same for rest of the events.

        private void OnMouseMove(object sender, MouseEventArgs e)
        {
            if (drag)
            {
                double x = e.GetPosition(BaseCanvas).X;
                double y = e.GetPosition(BaseCanvas).Y;
                AdjustLens(x, y);
            }
        }

        private void OnMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            if (drag)
            {
                MagnifyCanvas.Visibility = Visibility.Collapsed;
                ((FrameworkElement)sender).ReleaseMouseCapture();
                drag = false;
            }
        }

AdjustLens() helps to position Magnifier as per mouse movements and position of Canvas.

private void AdjustLens(double x, double y)
        {
            Lens.Center = LensBorder.Center = new Point(x, y);
            MagnifyCanvas.SetValue(Canvas.LeftProperty, (1 - scale) * x);
            MagnifyCanvas.SetValue(Canvas.TopProperty, (1 - scale) * y);
        }
  So build the project, you will get output as follows.

After applying Magnifier by dragging mouse, it will look like..

If you notice, you can see a Big Ellipse on right corner of the screen which shows a Bird is zoomed up, you can implement Magnifier while Video is in Run mode and it will not disturb the execution of video neither it will break any frame, It will run as smooth as it runs normally.

Hope this post will give you idea about implementation of Magnifier in Silverlight application and inspire you to implement it like I inspired and remake it from Jeff’s blog.

Vikram.
