7 useful QBasic programs and graphics,programming language software.

QBasic is a programming language developed by Microsoft in 1985.It is the successor of earlier forms of BASIC (Beginners All-Purpose Symbolic Instruction Code).QBasic is an ideal programming language for beginners because of its simple commands, improved programming structures,better graphics and flexibility.It is an integrated development environment (IDE) to write, edit, debug and execute basic programs.

Now lets review some Qbasic programs.

Microsoft has decided to drop the price of its Surface Pro tablet by $100.

Microsoft has decided to drop the price of its Surface Pro tablet by $100.
After slashing the price of the Surface RT, Microsoft has now followed on with a similar discount on the Pro model. The firm's second Windows 8 tablet price has been cut to $799 for the 64GB model – a drop of $100.
The 128GB Surface Pro has also been cut by $100 to $899. See also: Microsoft Surface RT price drops in the UK, by 30 percent.
Furthermore, opting for the Surface Pro Bundle (Office Home and Student 2013, a two-year warranty, a Type Cover, Incipio sleeve and a screen protector), costs $309 instead of $478.
These discounts apply in the US, Canada, Hong Kong and Taiwan but not the UK. The tablet still starts at £719 for the 64GB model and £799 for 128GB.
It's unclear whether Microsoft will introduce the discount to the Surface Pro or not. It recently dropped the Surface RT price to £279, a discount of £120.
Microsoft also reported woeful amounts of revenue from the two Surface tablets, just $853 million when a loss of $900 million has already been announced for its Surface RT, put down to 'inventory adjustments'.
The price cuts add to the rumour and speculation that Microsoft will launch new versions of the Surface tablets later this year with Windows 8.1. It's likely that the firm is trying to shift remaining stock of its home-grown device before unveiling their replacements.
Microsoft will be hoping the Surface 2 tablets will be more of a success. Little is known about the gadgets but they will come with a larger range of accessories, according to a leaked roadmap.

Microsoft announced or previews visual studio 2013.

Microsoft announced the availability of Visual Studio 2013 preview among
other major updates relevant to mobile app developers at its BUILD
conference.
Microsoft made several new announcements at the Build conference yesterday, the most important one among them being the preview of the newer versions of Visual Studio 2013 and .NET framework. An update for Visual Studio 2012 was also released, which includes bug fixes and enables Visual Studio 2012 to run on Windows . While the VS 2013 preview included a slew of new features related to Azure and cloud based testing. There is also a lot of focus on testing how the battery life of a device will be affected, power consumption for which can be measured down to the milliwatt. Other cloud related integration's come in the form of connectivity to Windows Azure Mobile Services and synchronization for developers to multiple devices. S. Somasegar, the VP for Microsoft Developer division said, “As just one example, .NET developers have been asking for a feature that’s been available to C++ developers for a while: viewing method return values in the debugger, even if those values are never stored into any declared variable. With .NET 4.5.1 and Visual Studio 2013, this capability is now built-in.”

The company also announced that it is opening up a lot of functionality of Bing as a platform for developers, wherein they will be able to access Bing data in a variety of different forms. They will also be able to access the knowledge base, entities, Optical Character Recognition, mapping etc.

The third major announcement that Microsoft made was related to the Internet Explorer browser, wherein it confirmed that for the first time ever, it will support WebGL. As of now, IE is the only major browser that does not yet support this features and it seems the functionality is finally coming, for everyone’s delight. There might be a lot of small announcements which were made, however these are some of those which took the stage away.

Microsoft issues tools to block IE10 upgrades on Windows 7

Move signals that the new browser won't ship for several weeks

Microsoft has released tools to block Internet Explorer 10 (IE10) from automatically reaching corporate PCs running Windows 7, a sign that the new browser will not release for at least several weeks.

• Microsoft gets silent upgrade religion, will push IE auto-updates

The IE10 Automatic Update Blocker Toolkit is designed for enterprises that want to keep workers on an older edition of IE. Its tools include a script that can be run locally, as well as an administrative template IT administrators can use to widely block IE10 through Group Policy settings.
The tools block automatic upgrading of older editions of Internet Explorer to IE10 on Windows 7 and Windows Server 2008 R2 via the operating systems' built-in Automatic Update service. Companies that rely on WSUS (Windows Server Update Services) or SMS (Systems Management Server) do not need the toolkit; they can manage the deployment of IE10 using those programs.
Individuals can also use the toolkit to keep IE10 off their Windows machines.
Microsoft has issued similar toolkits for IE7, IE8 and IE9 prior to those browsers' public releases. For the last two iterations, Microsoft offered a toolkit approximately one to two months before the release of the browser.
If Microsoft hews to the same timetable -- probable, since the idea is to give companies time to deploy the block -- IE10 will launch as soon as the first week of March, but perhaps as late as early April.
March is the more likely of the two; Microsoft shipped IE8 and IE9 that month in 2009 and 2011, respectively.
The IE10 blocking toolkit is even more important than its predecessors because of a change in how Microsoft upgrades customers' PCs to the latest version of the browser.
In late 2011, Microsoft announced it would silently upgrade IE to the newest version suitable for a user's version of Windows. Windows XP users still on IE6 or IE7, for example, would be updated to IE8, while Windows Vista or Windows 7 users running IE7 or IE8 would be pushed to IE9.
Before that change, Microsoft had asked for user permission before upgrading IE from one version to the next, even if Windows' Automatic Updates was enabled.
Because only Windows 7 and Windows 8 support IE10, Automatic Updates will upgrade the former to IE10 in the background, shortly after the browser is released. Windows 8 comes with IE10.
IE10 on Windows 7 is currently available as a preview, but Microsoft has repeatedly declined comment when asked when it would debut in final form. Last year, Computerworld predicted that the final release would appear in late 2012, basing that estimate on the development timetable for IE9. Instead, the browser will launch this year.
The 2013 release of IE10 puts to rest earlier speculation that Microsoft would accelerate its browser release cycle, and issue a new version annually. Analysts came to that conclusion after Microsoft announced IE10 just weeks after the March 2011 release of IE9.
IE10's most controversial feature is the "Do Not Track" (DNT) privacy setting, which Microsoft switches on by default. Online advertising representatives have blasted Microsoft's unilateral decision to enable DNT on IE10, warning that it could mean the end of many free services supported by advertising. Microsoft, in turn, has refused to back down.
The blocking toolkit, which will not bar upgrades on systems where the IE10 Release Preview has been installed, and which cannot prevent users from manually installing the new browser, is available from Microsoft's website.
