How to run turbo C++ in Fullscreen mode

When you try to run turbo c++ IDE on latest version of windows like Windows7 or Vista, you may get the error message that 'The system does not support full screen mode. Choose close to terminate the application.'

The problem is that turbo C is very old DOS program. It's better to move on to an up to date compiler like visual c++ Express which is free and you certainly would have a better experience.

Anyway if you are up with turbo c++ and used to it, I have 3 tricks to run it full screen on windows7 and vista. The tricks can be simply classified based on which works on all versions of windows7 and one which only works under Windows 7 Enterprise, Windows 7 Professional, and Windows 7 Ultimate.

Technique 1

Log on to windows7 in safe mode. In safe mode the application running capabilities of an operating system is low and this mode is used as trouble fixing for OS. But this method is much simpler and you only need to log on to safe mode by pressing F8 on start up.

By summarizing the steps:

1. Install turbo C++
2. Start windows7 in safe mode.
3. Execute turbo C++

Technique 2

By Disabling your graphics adapter.  This trick is done by just uninstalling the graphics driver. To do that

1. Right click on My Computer, click Properties
2. Select Device manager->Display Adapters
3. Identify the display adapter of your computer, and uninstall.

You should try this trick only if you do not use your computer for Graphic related operations like playing multimedia games.By this trick graphics would look vulgar but you can run C++ in full screen.

Technique 3

By using DOSBox software. It is an  open source DOS emulator for BeOS, Linux, Mac OS X, OS/2, and Windows. This tool is primarily intended to play DOS games on windows7 but here we can use it run turbo C++ in Full screen mode.

1. Download DOSBox frome here. (for windows)
2. Install and run the DOSBox.
3. Now a command prompt type window will appear. We need to mount TC folder. 

              Just type “mount c: c:/tc” and press enter. 

• Assumed that Turbo C++ is installed in C drive and TC folders located at C:\TC
• You may get a message that 'Drive C is mounted as local directory C:/TC\'                             
• Change the directory to C/BIN/tc.exe. To do that, please follow the steps as shown in the below screen shot.

Now the Turbo C++ will open in DOSBox. Press ALT+ENTER  to toggle between full screen and mini screen.

 

 

By applying the above 3 tricks, you can run C compiler on full screen mode in windows 7.

In many videos, sound track may be lead over video track.But this problem is identified by media player coders, and they attached an option to fix the desynchronization of video. All you have to do is play your media file in VLC media player or Media Player Classic (MPC) and identify shift direction. Then you will be able to adjust the audio shift.

How to increase the processor power of your computer

Today tip is very useful for those users who are still using computer with minimum processor speed. To increase the performance of slow computer, you can force your system to free up the idle tasks that are running in the background and sharing processor power. This end tasks method force the computer to devote its full processor resource to what you want it to do.

Preview files while downloading with IDM

IDM - Internet download Manager software is one of the best download managers that  uses dynamic file segmentation and safe multipart downloading technology to accelerate file downloading. Often if we download large files like movies, we want to check that the file which is downloading is correct. But IDM users have no option to preview movies or songs while downloading except rar preview. But this can be achieved by a simple trick. You only have to follow these steps.

Things to Note: IDM multipart technology uses file splitting before downloading to boost downloading speed. This is why the file preview is not available in IDM. If you send a request to download a file using IDM, it splits file into pieces, then download each part in a sequence. However this tech may slow down download some times in my experience. For full preview of the downloading file, you have to disable this file splitting. 

To do this, goto IDM options by clicking Downloads > Options. Click on Connection tab. Enter Default Max. Connection Number as 1. then click Ok. Then download you file.Your further downloads may look like this:

Steps to Preview Files While Downloading with IDM

1. Open IDM the click Downloads > Options, Save to tab.

 

2. Look for the temporary  path where IDM stores the uncompleted download parts.

3. Go to the location in your computer and find your file name that you were currently downloading. ( This can be done by goto DwnlData in temp folder the arrange files by modified by right click. )

4.  You will have a file and a log file in it. You are almost done. 

5. To preview the file open the file using VLC media player (If you are downloading a movie)

You can play the file as much as the download progresses.

Windows 7 Tips and Tricks

1.PC Safeguard

I rarely let anyone use my PC because I’m afraid he will mess it up, but it seems Microsoft has been thinking at me and came with a solution. The PC Safeguard doesn ’t let anyone mess your PC
settings, because after the user logs off, the configurations are reset
back to normal. Of course it will not restore the configurations changed by you, but only the ones
done by other users you define.
To use PC Safeguard, go to Control Panel -> User Accounts and create a new account, then select “Set Up Pc Safeguard ” and switch it on. Then you can stay relaxed when others use your computer, because
you won ’t find anything changed, including configurations,downloaded software,installed programs.

2. Screen Calibration Fortunately

Windows 7 comes with a display calibration wizard that lets you set up the screen brightness properly, so
you won ’t have any problems viewing photos or text. The problem was that on one PC a photo
could look sharp and bright and on another it looks awful. Now the problem can be fixed by
pressing the Windows logo key and then typing “DCCW”.

3. AppLocker

If you are usually sharing your computer with someone else, then you might want to restrict their access to your applications, files or documents. Using the Windows 7 AppLocker tool, you have a few options to do this by blocking other users to access Executables, Windows Installers, Scripts, a specific publisher or path. You can simply do this by pressing the Windows key then typing Gpedit.msc. Then go to ComputerConfiguration -> Windows
Settings -> Security Settings -> Application Control
Policies -> AppLocker.
Right click on one of the options (Executables,Installers, or Script) and
create a new rule. That should save you from a lot of headaches.

4. Burn Images

We all had trouble with image burning in Windows, because it couldn ’t do it itself, a standalone software being needed. With Windows 7 this will not be a problem anymore. All you have to do is double-click the ISO image and burn it on the CD or DVD that ’s inserted in the drive.

5. Display Empty

Removable Drives Windows 7 will not showempty drives by default, so if you connect an empty
drive to your PC, don ’t worry, just go to Tools ->Folder Options -> View and uncheck “Hide empty drives in the computer folder ”. This doesn ’t seem like a good idea and it should not be default
setting, because it will be hard for inexperienced users to figure it out. I bet a lot of users will return their newly bought drive thinking it ’s broken.

6. Dock The Current

Windows To The Left Side Of The Screen This new feature seems useful because sometimes it’s disturbing that windows seems to float like crazy on the screen and it’s hard to attach them to one side of it. Now this
can easily be done using a keyboard shortcut. Press the Windows key + Left key (arrow) to dock it to
the left side of the screen. 6.1 Dock The Current Windows To The Right Side Of The Screen Press the Windows key + Right key to dock it to the right side of the screen.

7. Display Or Hide

The Explorer Preview Panel Press ALT + P to hide it then once again to display it.

8. Display Gadgets On Top

Of Other Windows Press ALT + G

9. Background Photo Slideshow

If you are like me, lazy and bored, then you will want to change the background from time to time, wasting
a lot of time. Now you don’t have to do this anymore, because you can set up a slideshow. Right click on the desktop then go to Personalize ->Desktop Background and hold the CTRL key while choosing the images. Then you can choose the time intervals between imagesand opt to display them randomly or in a row.

10. Make The Taskbar Smaller

If you feel like the taskbar is using too much of your screen space, you can choose to make the icons smaller. To do this, right-click on the Start button, then go to Properties ->Taskbar and set it to “Use small icons”

8. Copy your Windows 7/Vista DVD contents to the USB flash drive.
9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.
Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB.

Use Hidden Wallpapers and Themes on Windows 7

When you first install Windows 7, it asks for your language, time and currency. Based on your responses, it installs a set of wallpapers and themes. If you choose English (United States) for your time and currency format, for example, the available desktop backgrounds and themes will include a United States section with scenery from locations such as Maine, the Southwest and so on.
Hidden, though, are background scenery and themes from other English-speaking countries -- Australia, Canada, Great Britain and South Africa. Normally, you can't access those backgrounds or themes, but there is a simple way you can install and use them:

1. In the search box in the Start menu, type C:\Windows\Globalization\MCT and press Enter. (Note: If Windows 7 is installed in a drive other than C:, use that letter instead.)

2. Windows Explorer will launch and show you a list of subfolders under C:\Windows\Globalization\MCT: MCT-AU, MCT-CA, MCT-GB, MCT-US, and MCT-ZA. Each subfolder has wallpapers for a specific country: AU for Australia, CA for Canada, GB for Great Britain, US for the United States, and ZA for South Africa.

For any of the countries whose wallpaper and themes you want to use, go into its Theme folder, for example, C:\Windows\Globalization\MCT\MCT-ZA\Theme. Double-click the theme you see there (for example ZA).

3. That will install a shortcut to the theme and wallpapers in the Personalization section of Control Panel.
You can now use them as you would any other theme or background, by right-clicking the desktop, choosing Personalize, and choosing a background or theme. They will be listed in their own section.
