I want to get the R, G and B components as integers (0-255). I use this: -
Rectangle area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
-
BufferedImage bufferedImage = r.createScreenCapture(area);
-
int pixel = bufferedImage.getRGB(x,y);
-
But it returns some crazy 1 value of -65536 or something like that. How do I convert it to three individual integers R,G and B?

That 'crazy' value represents the colour of the pixel as four bytes: alpha, red,
green and blue; the alpha factor is the transparency of the colour. You can
fiddle with the bytes in the int yourself to get the individual colour components
but you can also let the Color class do the work. You can instantiate a new
Color object given that int value. The Color object has applicable methods you
can use: getAlpha(), getRed(), getGreen() and getBlue().
kind regards,
Jos

Is there a purpose for using trailing and leading double underscores for
built-in method names? My impression was that underscores are supposed
to imply some sort of pseudo-privatization, but would using
myclass.len() instead of myclass.__len__() really cause Python
considerable harm? As much as I adore Python, I have to admit, I find
this to be one of the language's most "unPythonic" features and a key
arguing point against Python. I've...

Hello all,
I want to use the POST method to submit the form and then grab the
parameters in the asp file with request.form("parm").
The problem is that I am using the _search target to open the asp
page.
When I use _blank target there is no problem, either I use GET or POST
method.
But when I use _search target, only GET method works.

I am trying to understand Session variables and ran into a question on
how they work with data that is passed.
I have an HTM file that calls an ASP file and sends the name either by
GET or POST.
When I find is that if I send the value by the GET method,
response.write("From QueryString: " &
Request.QueryString("usernamefromform") & "<br><br>")

In ASP, when we pass data between pages, we usually pass by query string. If
we pass data by query string, that means we need to use submit button, not
by regular button, and the form will pass to the server since it's GET or
POST request. But if just form-to-form communication, why we need to send
the form to the server? Please help clarify. Thanks!!
<form action="process.asp" method="get">
//form controls
<input type="submit">

Hi,
I'm learning C# and I just don't quite understand the need for
polymorphism. why do we need to use it? how does a base class variable
holding a derived class instance do any good?
Also, what's the difference between method hiding and overriding when
they're both still overriding the base method.
Thanks

I want to create an MSI or Installshield (prefer MSI), to setup my C# app,

How can I detect if MSDE is already installed??
Has anyone does this?? How??
