Microsoft has announced that the company will no longer support the OneDrive Sync app on Windows 7, Windows 8, and Windows 8.1. This will come into effect starting . If you are using OneDrive on any of these platforms, upgrade to the latest version of Windows 10 or Windows 11.
In case your PC doesn't support Windows 10, or Windows 11, you will still be able to access your cloud files through the OneDrive web interface.
Sometime it's a question asked by people "What's the best antivirus product?" or "Do I need to install any 3rd party antivirus product on Windows 10?" etc. Ok, to answer this query, you must understand how much security you actually need.
In this post, I am going to answer this. Also, sharing some Microsoft recommended 3rd party good products which you can run (not mandatorily) as a primary antivirus software.
Microsoft announced that Windows 10 will be available on 29th July for new laptops, PCs and tablets. Apart from this, it will also be available as a free upgrade for a year for any devices currently running Windows 7 or Windows 8.1.
If you are currently running Windows 7 or Windows 8.x, it’s time for you to prepare your system to make sure that, you receive it immediately when the new OS is available.

Today morning when I checked my mail, I saw one mail regarding “Article of the day” from DotNetFunda.com mentioning one of my article titled “Windows 7 Multitouch Application Development (Part – I)” has been selected as “Article of the day” in Microsoft WPF site WindowsClient.Net.
Thank you DotNetFunda team.
Microsoft released their all new Operating System as expected. From now onwards it is available for the general public i.e. you can purchase a new PC/Laptop with Windows 7 preloaded. Not only this, those who recently purchased PC/Laptop with Windows Vista they are able to upgrade to Windows 7 free of charge. So, grab your copy now & enjoy the real experience with Windows 7.
For last couple of months I am using the trial edition of Windows 7. According to me, it is a great operating system Microsoft had ever launched with lots of goodies. My special thanks to Microsoft & Windows 7 team for their excellent work.
No doubt this is really a great Microsoft Operating System with a huge performance boost, a great UI, new taskbar & multi-touch function. Here are the list of things I liked more in Windows 7:
It’s definitely a great ERA in the computing world.
It’s a great day in the Microsoft era. They are going to launch the official release of Windows 7 today. From now onwards, this will be available to purchase all over the world.
You can view the Windows 7 Launch celebration here directly from New York city, which will be hosted by Steve Ballmer. This will start at 8 AM (Pacific) / 11 AM (Eastern).
In my last post Windows 7 Multitouch Application Development (Part - I), I described about how to handle multitouch image manipulation in Windows 7 which gives a very basic idea on the multitouch development. That code uses multitouch manipulation for the entire screen. If there are multiple images in the screen this will raise event for all.
In this post, I will show you how to manage multitouch events for all the images separately. See one of such kind of image manipulation demo here.
For this we have to assign a unique touch-id for each finger on the screen. As long as the finger touches the screen the associated touch-id will remain same for that particular finger. If the user releases his finger the system will release the touch-id & that can be again assign by the system automatically on next touch. So, how can we get the touch-id? You can get the same from the StylusEventArgs (i.e. args.StylusDevice.Id). The stylus device will automatically generate this ID for each touch, only thing is you have to assign it with the respective finger touch.
First of all, we will create an UserControl which will consist of a single Image & XAML code for it’s RenderTransform. The same thing we did in the previous post which was inside the Window, but here it will be inside the UserControl (Picture class). Create a DependencyProperty to assign the ImageLocation dynamically.
<UserControl x:Class="Windows7MultitouchDemo.Picture" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Image Source="{Binding Path=ImageLocation}" Stretch="Fill" Width="Auto" Height="Auto" RenderTransformOrigin="0.5, 0.5"> <Image.RenderTransform> <TransformGroup> <RotateTransform x:Name="trRotate"/> <ScaleTransform x:Name="trScale"/> <TranslateTransform x:Name="trTranslate"/> </TransformGroup> </Image.RenderTransform> </Image> </UserControl>
To track the multi-touch simultaneously for the above “Picture” usercontrol, you can use the PictureTracker class which comes with the Windows 7 Training Kit. You can download it from Microsoft Site. It looks similar to this:
/// <summary> /// Track a single picture /// </summary> public class PictureTracker { private Point _prevLocation; public Picture Picture { get; set; } public void ProcessDown(Point location) { _prevLocation = location; } public void ProcessMove(Point location) { Picture.X += location.X - _prevLocation.X; Picture.Y += location.Y - _prevLocation.Y; _prevLocation = location; } public void ProcessUp(Point location) { //Do Nothing, We might have another touch-id that is //still down } }
Now, we have to store all the active touch-ids associated with the PictureTracker class. So, we will use a dictionary for that. We will use the same PictureTrackerManager class which again comes with the Windows 7 Training Kit.
private readonly Dictionary<int, PictureTracker> _pictureTrackerMap;Create an instance of the PictureTrackerManager class inside your Window1.xaml.cs & register the stylus events with the PictureTrackerManager events. So now whenever a touch occurs on the Picture, the PictureTrackerManager will first find the associated touch-id for the respective instance and raise event to process the same.
//Register for stylus (touch) events
StylusDown += _pictureTrackerManager.ProcessDown;
StylusUp += _pictureTrackerManager.ProcessUp;
StylusMove += _pictureTrackerManager.ProcessMove;

<Grid> <Image Source="images/Hydrangeas.jpg"/> </Grid>Add RenderTransform to the image so that, we can scale or rotate the image properly. This will produce XAML similar to this:
<Grid> <Image Source="images/Hydrangeas.jpg" RenderTransformOrigin="0.5,0.5" Width="400"> <Image.RenderTransform> <TransformGroup> <ScaleTransform x:Name="trScale" ScaleX="1" ScaleY="1"/> <RotateTransform x:Name="trRotate" Angle="0"/> <TranslateTransform x:Name="trTranslate" X="0" Y="0"/> <SkewTransform AngleX="0" AngleY="0"/> </TransformGroup> </Image.RenderTransform> </Image> </Grid>Use proper names when you are adding different types of transform to the transform group. It will be easier for you to handle it from the code behind file. Run your application. This will open up your Window with an image inside it. If you want to drag or rotate the image this will not work because we haven’t integrated the functionality yet. Add two project references i.e. “Windows7.Multitouch” & “Windows7.Multitouch.WPF” from the extracted zip folder to your solution. These are the managed API codes for multitouch application development. Go to your Window1.xaml.cs & be sure that following namespaces are already included. You may have to add some of them.
using System; using System.Windows; using Windows7.Multitouch; using Windows7.Multitouch.Manipulation; using Windows7.Multitouch.WPF;Create two private members inside your partial class:
// object of a .Net Wrapper class for processing multitouch manipulation private ManipulationProcessor manipulationProcessor = new ManipulationProcessor(ProcessorManipulations.ALL); // boolean value to check whether you have a multitouch enabled screen private static bool IsMultitouchEnabled = TouchHandler.DigitizerCapabilities.IsMultiTouchReady;Now inside the Window Loaded event write the following lines of code:
// check to see whether multitouch is enabled if (IsMultitouchEnabled) { // enables stylus events for processor manipulation Factory.EnableStylusEvents(this); // add the stylus events StylusDown += (s, e) => { manipulationProcessor.ProcessDown((uint)e.StylusDevice.Id, e.GetPosition(this).ToDrawingPointF()); }; StylusUp += (s, e) => { manipulationProcessor.ProcessUp((uint)e.StylusDevice.Id, e.GetPosition(this).ToDrawingPointF()); }; StylusMove += (s, e) => { manipulationProcessor.ProcessMove((uint)e.StylusDevice.Id, e.GetPosition(this).ToDrawingPointF()); }; // register the ManipulationDelta event with the manipulation processor manipulationProcessor.ManipulationDelta += ProcessManipulationDelta; // set the rotation angle for single finger manipulation manipulationProcessor.PivotRadius = 2; }Write your logic inside the manipulation event handler implementation block. Here I will do rotation, scaling & positioning of the image. Here is my code:
private void ProcessManipulationDelta(object sender, ManipulationDeltaEventArgs e) { trTranslate.X += e.TranslationDelta.Width; trTranslate.Y += e.TranslationDelta.Height; trRotate.Angle += e.RotationDelta * 180 / Math.PI; trScale.ScaleX *= e.ScaleDelta; trScale.ScaleY *= e.ScaleDelta; }From the ManipulationDeltaEventArgs you can get various values & depending upon them you can implement your functionality in this block. TranslateTransform will position the image, RotateTransform will do the rotation & the ScaleTransform will resize the image. Run your project to test your first multitouch application.
