You can clear the fields without reloading the form by keeping a 'RESET' button on your page.

<html>
<head>
<title>Sample</title>
<script type="text/javascript">
    function fillValue(frm)
    {
        frm.err.value = "ERROR";
    }
</script>
</head>
<body>
    <form name="frm">
    <label for="error">Error</label>
    <input type="text" id="err" name="err" />
    <br />
    <input type="button" value = "Calculate" onclick="fillValue(this.form);"/>
    <br />
    <input type="reset" value="reload" />
    </form>
</body>
</html>

Or if reloading is necessary, do something like:

<html>
<head>
<title>Sample</title>
<script type="text/javascript">
    function fillValue(frm)
    {
        frm.err.value = "ERROR";
    }
    function clearAndReload(frm)
    {    
        location.reload();
        frm.reset();
    }
</script>
</head>
<body>
    <form name="frm">
    <label for="error">Error</label>
    <input type="text" id="err" name="err" />
    <br />
    <input type="button" value = "Calculate" onclick="fillValue(this.form);" />
    <br />
    <input type="button" value="Reload" onclick="clearAndReload(this.form);" />
    </form>
</body>
</html>

This is happening because you are setting the fill color as well as the border color of the fill to the same color i.e. RED.

This is confusing the floodfill algorithm which checks the color of the neighboring pixels to determine when to stop. By making the border RED, the check is never unsuccessful and it fills up the entire screen. This seems to be a bug with the function since this is not expected but you have got to live with it. :-)

Choose different colors for floodfilling and its border and you should be fine. Oh and BTW, main returns an int and not void.

#include<stdio.h>
#include<graphics.h>
//you don't need conio

int main(void)
{
  int driver,mode;
  driver = DETECT;
  initgraph(&driver,&mode,"\\tc\\bgi");  
  rectangle(105,90,125,110);
  setfillstyle(SOLID_FILL, RED);
  floodfill(115, 100, WHITE);
  getchar();
  closegraph();
  return(0);
}

}

This can't be done in Javascript since its a client side technology. The only thing a Javascript code can store on client's machine is cookies which can't exceed 4KB, so I guess its out of question.

Re: please help me

Either you didn't read the entire blog or you missed the point. The point the author was trying to put across was that the Java Imaging API when compared to other languages is pretty much prehistoric. Did you glance at the Python example he demonstrated? Don't you think doing your project is Python would have consisted of significantly fewer lines of code?

Java is known for its boilerplate code. He just wanted to say that in the world of Fourth Generation languages, a matured language like Java could have done better. Come to think of it, even James Gosling agrees to it.

Re: y we can not initialize the fields in the construtor in the servlet?

~s.o.s~ 2,560 Failure as a human

Satish, store the client information / state in client session i.e. session variables. Since the servlet class is loaded in memory on its first invocation and the client reqests just result in the creation of thread, storing state in servlet instance variables would make them kind of global, i.e. accessible by each and every client.

To store common information related to the entire web application, look into the <context-param> element of deployment descriptor. To store common information related to a particular servlet, look into <init-param> element of deployment descriptor.

Re: Word Descrambler....

well damn my compiler for giving me access to for each.
let's write a while statement then!
string foo = "super duper long string of wooorrrdddsss";
int c = 0;
while ( c < foo.length() )

Computationally expensive. length() function is called each time the loop is executed. Why not something simple like:

int length = foo.length();
for(int i = 0; i < length; ++i)
   cout << foo[i] << '\n';

> atoe[0][0] == atoe[0][1] == atoe[0][2]
This line doesn't do what you think it does. The evaluation of this expression is from left to right so the result of the first comparison(between first and second term) is then compared with the third term.

Create a function called 'threeEqual' with something like this:

bool threeEqual(char a, char b, char c)
{
    return((a == b) && (b == c));
}

// and call it in your program as

bool WinVert( char atoe[][3]) //Boolean data type to check for winning rows/column.
{
    return (threeEqual(atoe[0][0],atoe[0][1],atoe[0][2]) ||
            threeEqual(atoe[1][0],atoe[1][1],atoe[1][2]) ||
            threeEqual(atoe[2][0],atoe[2][1],atoe[2][2]));
}

Plus you have interchanged the names of the functions. The one named WinHori should be WinVert and vice a versa.

Re: display:block to show a table?

> Hello, and congratulations for this beautiful and meticulous forum.
Hello and welcome. :-)

Now to your problem. 'display' property of CSS decides how an element would be displayed. Since you already have a table, it doesn't make sense to set the display property to table.

Normally this property is used to alter the way a paragraph, a div block or a span block i.e. any container tag displays the data. So what to do when the tag under consideration is a 'table' tag? Simple, set its property to nothing.

<table id="tab" border="1" width="100%">
  <tr>
    <td width="100%">test</td>
  </tr>
</table>

and when making it hidden do something like:

<html>
<head>
    <script type="text/javascript">
    function hide(id)
    {
        document.getElementById(id).style.display = 'none';
    }
    function show(id)
    {
        document.getElementById(id).style.display = '';
    }
    </script>    
</head>
<body onmousedown="hide('tab');" onmouseup="show('tab');">
<table id="tab" border="1" width="100%">
    <tr>
        <td>test</td>
    </tr>
</table>
</body>
</html>

Re: C++ n C

Thats why I specifically highlighted the term 'functional'. If you know C its just a matter of developing the OO mentality. Plus a good beginner book doesn't dwell on the OO part of the language but what can be achieved with the language.

Come to think of it, C++ is IMO not pure OO. It gives you the impression of OO features being added to an imperative language to make it a mainstream one (OO was the buzzword in those days).

Removing third character from the string is pretty simple. I don't think an university assignment would be that easy. But I guess we would just have to wait for the OP to clear our doubts.

Re: Help Please - with String Manipulation

~s.o.s~ 2,560 Failure as a human

You end up removing the fourth character instead of the third one. Doing if(i % 3 == 2) would solve the problem.

But I still think that removing third character from each _word_ is different from removing third character from the string as a whole.

The coordinates are working fine in my case. There must be some error on your part. Post the code if it still doesn't work.

As for executing a function when the window closes, you can use the onunload callback function.

Here is an example:

<html>
<head>
<script>
    function doSomething(e) {
        var posx = 0;
        var posy = 0;
        if (!e) var e = window.event;
        if (e.pageX || e.pageY)     {
            posx = e.pageX;
            posy = e.pageY;
        }
        else if (e.clientX || e.clientY)     {
            posx = e.clientX + document.body.scrollLeft
                + document.documentElement.scrollLeft;
            posy = e.clientY + document.body.scrollTop
                + document.documentElement.scrollTop;
        }
        alert(posx + ", " + posy);
    }
    
    function confirmMe()
    {
        alert("Thank you for visiting us!!");
    }
</script>
</head>
<body onunload="confirmMe();">

Re: print web page

But you have got to realize that the window.print() method provides little or no control over the printing settings. Its just a nicety and is equivalent to pressing Ctrl + P.

Even the documentation doesn't provide any significant information about this function. It actually makes sense since its the user who decides what and how things have to printed and not the site developer. Messing around a bit with your printer settings is the only way to go.

Re: Two-dimensional char array

A real world use of two dimensional arrays is for representing matrices. Here is an example of 3 x 3 identity matrix:

int matrix[3][3] = {0};
for(int i = 0; i < 3; ++i)
{
    for(int j = 0; j < 3; ++j)
    {
        if(i == j)
            matrix[i][i] = 1;
    }
}

//For printing this matrix
    for(int i = 0; i < 3; ++i)
    {
        for(int j = 0; j < 3; ++j)
        {
            cout << "   " << matrix[i][j]) << "   ";
        }
        putchar('\n');
    }

The output after printing this matrix would be:

1   0   0
0   1   0
0   0   1
