Testimonial for My College 
"The computer technology changes very fast and those who are not able to match with it are left behind forever. I am thankful to SVIET for providing the training programs and workshops on latest technology in the college, equipped me for the challenges of the IT sector. I remember when I joined MCA, I was totally confused. I had taken it up as it was in vogue. But the guidance provided by Ms. Kawaljeet Kaur (HOD MCA) helped me a lot. I thank my Computer Application Department for encouraging me to think globally and spread my wings to take off for the land of rising sun. I am confident that my future is very bright and I would make my college and my parents proud"

Create File and Folder with Name "CON" in Windows

Most of people wondering, when hear that we cannot create a folder with the name CON.
Simple ppl dont know why they cant create File named with "CON"? Very few know that they can still create it someway. why are they supposed to do exactly like that.. Now, After reading this tutorial, you will become one of the rest. Not only CON, we cannot create any of these:

CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more.

 The reason is that con, prn, lpt1..lpt9, etc are underlying devices from the time dos was written. so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is -- it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one. So Now, Try this... 
 C:\> md \\.\x:\con

Note: x: represent the Drive letter where want to create. (it may be C:, D: and So on)
Now, Open My Computer and browse through the path where you created CON folder ... Surprising.. ?? Yeah.. you have created it successfully..
Now, try to delete the folder from My computer
OOPS!!! You cant delete it...

Now, try this in command prompt console
C:\> RD \\.\x:\con

You Did it

Laptop Touch Pad Click option doesn't woked

Last day when I am working on my QT (Its name of my laptop). A problem is occurred, that is after restarting windows touch pad of laptop doesn’t work perfectly. There was some error, It works well for moving the mouse pointer. But click and double click operation cannot performed by touch pad, even left and right click button works fine. I was shocked. I was trying to sort out the problem by control panel, there was nothing to do. Finally I restored the computer at previous time. It still not worked. At last I googled the problem. I searched a lots of solution but that was not worked. Suddenly, I think why not download the touch pad drivers. In some solution I found that if device setting tab available in mouse property then our problem could be solve. That very option didn’t appear in my mouse property. So, I am tensed. After then I downloaded the driver called  
                                            Synaptics Pointing Device Driver

Any one can download it from there Laptop manufacturer website or anywhere. Here is the link that can be also work for most of laptop (HP, Acer, Lenovo, Sony, Toshiba and more)
Click on download button 
Download


After installation of software restart you PC and open the mouse device setting by

Start | Cotrol Panel | Hardware and Sound category | click on "mouse"

OR 


Start | Type “main.cpl”

In both case a dialog box will appear like

Now click on Device Setting tab. Then following dialog box will appear that is use to enable and disable the pointing devices. We can also hide / show driver icon from system tray using following box.
 
 For my problem
 I used the settings.. button then another window will open


Here taping option provide a lots of facility from where, I just select enable tapping option and my problem had been solved.

Note: Snaptics driver can not only used for touch pad of laptop but also used for other pointing devices.
From this setting we can control the speed scroll, gestures and many more setting easily that increase the value of touch pad. Some video tutorial also included that can help in understanding the touch pad technique.
