Removing Irritating "Undeleteable" Files !

How to delete those frustrating files that, when you drag them to the Recycle Bin, give you a frustrating message along the lines of: “Cannot delete file: It is being used by another person or program.”

Here’s the post, and here’s the simple first step from that post, outlining how to delete an “undeleleable” file:

* Open a Command Prompt window and leave it open. Close all open programs. (Click Start > Run and type CMD to open a command prompt.)
* Click Start, Run and enter TASKMGR.EXE. (Or just click Control-Alt-Delete to bring up the Task Manager.)
* Go to the Processes tab and click End Process on Explorer.exe. Leave Task Manager open.
* Go back to the Command Prompt window and use the CD command to get 2 the directory with the bad file.
* At the command prompt type DEL and where the file you wish to delete is.
* Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell. Close Task Manager.

Now this may not always work, but it should more often than not. The other option is a freeware application that can close the file for you. Unlocker is just such a beast. Install the application, then when you encounter one of those “file in use” errors, just right-click the file and select Unlocker. Click Unlock All and the files will be taken care of. No command line required. It’s definitely worth a download!

Definitely worth a download! – unlocker

2. Open the help-window by pressing the F1 key.
3. Click the top-left corner icon of the help window once (Standard is a Document with a Questionmark).
4. Select Go to URL-address.
5. Type your address into the avaliable field, but remember to type http://, and not just www. (or equivalent).
6. Have fun!

Hope you remember this in case all else should fail!

Anonymous Surfing

Have you ever wanted to surf the web anonymously? While surfing the web, you leave your information literally EVERYWHERE. I wanted to find a way to use the Internet and not give my information out to everyone. I did some research and came across this website. Basically what it does is cloak your IP address therefore cloaking you. It is very easy to use and is done fully within the website, no software downloads needed. This is also great for sites that you are unsure of their authenticity. Never take a chance of having these sites steal your information and sell it. The website is called the-cloak.com. So check it out and let me know if it works for you as well as it has worked for me.

Find the nth element from the back of a singly linked list

This is most ever question asked by many top companies.

The question goes as follows :
How would you find the nth element from the back of a singly linked list?

And the following might be a solution:
1) have two ptrs. F_Ptr & S_Ptr.
2) Let the ptrs point to the START.
3) Take n as the offset.
4) Start traversing the S_Ptr after the F_Ptr after n.

Suppose u want to find 5th element from the last of the list, then
1) n = 5 // 5th element from the last
2) check atleast this many elements are there in the list before begining

// traverse the F_Ptr offsetfor(;n!=0;n--,F_Ptr->next);
// now set the S_Ptr to trail the F_Ptr
S_Ptr = F_Ptr;
for(;F_Ptr!=NULL; S_Ptr=F_Ptr; F_Ptr=F_Ptr->next)

Now when F_Ptr = Null, S_Ptr is just trailing behind right! it will be pointing to the n'th element from the last.

When F_Ptr reaches end (i.e., F_Ptr is NULL)S_Ptr points to the 5th element from the last.

Avoiding Unnecessary Bugs

A typo often made by even the most experienced programmers is placing an if (a = 1) statement where an if (a == 1) is meant. Instead of checking whether the value of variable a equals 1, the first statement will assign the value 1 to a, and the if will always be true. These kinds of bugs can be very hard to find but are easily avoided by simply adopting a different coding style. When you train yourself to turn around the elements of which the expressions are made up, the compiler will 'warn'you when you make this kind of typo.

if (1 == a)
if (NULL == fp)
. . .
By placing the constant first, the compiler will complain about you trying to assign a value to a constant as soon as you forget the second =.
