MAGIC #1

In windows…try to rename a folder or create a new folder named as ’con’..it will not create a folder named as con….try it out…

MAGIC #2

For those of you using Windows, do the following:

1.) Open an empty notepad file

2.) Type "Bush hid the facts" (without the quotes)

3.) Save it as whatever you want.

4.) Close it, and re-open it.

is it just a really weird bug? :-??

MAGIC #3

Microsoft crazy facts

This is something pretty cool and neat...and unbelievable...

It was discovered by a Brazilian. Try it out yourself...

Open Microsoft Word and type

=rand (200, 99)

And then press ENTER

then see the magic...............................

Reson for the 1st:

The following reserved device names cannot be used as the name of a file:

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

CON is reserved for console, PRN is reserved for printers...........etc.

You must avoid using these names as a file name suffix or file name body, so you have to avoid names such as aux.c, file.aux or NUL.txt.

Reason for the 2nd:

You see, text files containing Unicode (more correctly, UTF-16-encoded Unicode) are supposed to start with a "Byte-Order Mark" (BOM), which is a two-byte flag that tells a reader how the following UTF-16 data is encoded. Given that these two bytes are exceedingly unlikely to occur at the beginning of an ASCII text file, it's commonly used to tell whether a text file is encoded in UTF-16.

But plenty of applications don't bother writing this marker at the beginning of a UTF-16-encoded file. So what's an app like Notepad to do?

Windows helpfully provides a function called IsTextUnicode()--you pass it some data, and it tells you whether it's UTF-16-encoded or not.


It actually runs a couple of heuristics over the first 256 bytes of the data and provides its best guess. As it turns out, these tests aren't terribly reliable for very short ASCII strings that contain an even number of lower-case letters, like "this app can break", or more appropriately, "this api can break".

The documentation for IsTextUnicode says:

These tests are not foolproof. The statistical tests assume certain amounts of variation between low and high bytes in a string, and some ASCII strings can slip through. For example, if lpBuffer points to the ASCII string 0x41, 0x0A, 0x0D, 0x1D (A\n\r^Z), the string passes the IS_TEXT_UNICODE_STATISTICS test, though failure would be preferable.

Reason for the 3rd:

Actually "Rand" is a word function.


Microsoft Word allows you to quickly insert sample text into a document. To do this, type =rand() in the document where you want the text to appear, and then press ENTER.

The inserted text is that hardy perennial: “The quick brown fox jumps over the lazy dog,” which contains every letter in the English alphabet.

By default, the sample text contains three paragraphs, each containing five sentences. You can control how many paragraphs and sentences appear by adding numbers inside the parentheses, for instance:

=rand(3,4)

The first number is the number of paragraphs, and the second the number of sentences per paragraph. If you omit the second number, you get five sentences in each paragraph. So, for example:

=rand(3,4)

inserts three, four-sentence paragraphs, while:

=rand(10)

inserts ten, five-sentence paragraphs.

The maximum number for either parameter is 200 and may be lower depending on the number of paragraphs and sentences specified. For instance, if you specify 200 paragraphs, then the maximum number of sentences per paragraph you can specify is 99:

=rand(200, 99)

If you specify 200 sentences per paragraph, then the maximum number of paragraphs you can specify is 99.

Admittedly, this function serves a useful purpose for filling a page when you’re designing a template and want to see how it will look with text in it. It’s also easy to see how users can be alarmed and fear this is a virus when someone suggests they try “=rand(200,99),” which quickly blows up into a giant document! (Incidentally, part of the instructions in some versions is to “Make sure there is a space between = and rand and a space between rand and (200,99).” This actually makes no difference: the function works equally well with and without Spaces.)
