Re: How do I prevent value and attribute delays?

There is something that doesn't work here:

The lengthy processing function requires values to be passed to it from the error display process. It does nothing to the values displayed, but it does need them to know what to calculate default values for.

I can't pass the values to the processing function if they haven't been set yet.

Also, site policy says I should not modify the html code with scripts. I need to set styles and values instead.

Also, you put in an alert. That alone will cause the display to complete. But I don't want to distract the user from what he is doing with an alert.

I guess I still don't get the big picture. As far as the processing function requiring the data is concerned, you can always make the function which is called before the processing function to make changes to the global variable(map or associative array). This way you don't need to pass anything. Plus you get to decide when to call the processing.

And the 'alert()' in my code was just an example.

Re: How do I prevent value and attribute delays?

Why not keep the function which just does only processing in background for while i.e. make use of setInterval and setTimeout functions which would give the code which displays names enough time to do its job.

Something like this:

<html>
<head>
    <script>
    var counter = 0;
    var hnd = null;
   
    function doSomething()
    {   
        //your lengthy processing function
        hnd = setInterval("calculate()", 3000);

        //your display function
        var d = document.getElementById('d');
        d.innerHTML = "<b>Hello to all</b>";
    }
   
    function calculate()
    {
        alert("Sum of 3  and 5 is 8");
        clearInterval(hnd);
    }
    </script>
</head>
<body onload="doSomething();">
    <div id="d"></div>
</body>
</html>

This way you can keep the function which consumes the most of CPU cycles to run at a later moment.

Re: Detect browser window closing event in Firefox -

It seems that you have never interacted with clients who insist on having a 'popup' window or some clean up routines to be performed when the user attempts on closing or unloading the window. Though this may seem like a nonsense requirement for public domain sites, it becomes a nifty feature for intranet sites.

Even Google makes use of this confirmation thingy (try composing a mail and going back to inbox without sending it) by either using the 'onunload' event or some other trick for rich and interactive user experience. Come to think of it, when you think of web revolution in terms of applications which behave more and more like the desktop applications, the onunload suddenly seems to be a required feature.

Think out of the box and you would see of the different ways in which you can use such events for the betterment of applications as well as UI.

My personal experience has been that Opera scales the worst when it comes to handling events displaying the most random behavior.

Re: C++ Help please with passing arrays

Why do you want to return a 2D array which is a member of the class when all you are doing in the 'population()' method is make changes to the same array? You can just call the 'population()' function in your constructor and your 2D array would have the updated/required values.

Re: C++ Help please with passing arrays

You can either pass the array considering as a sparse array i.e. by doing void someFunc(int** myArray) or you can pass it as a normal array by leaving off at the max the first dimension i.e. void someFunc(int myArray[][COLS]) . Also read this.

Consider constructing your 2D array using vectors since it is more flexible that way.

I guess this suggestion was put up before, but the problem being we can't add a 5 point infraction for not using code tags and it also doesn't make any sense. A warning or two or a two point infraction at the max. Plus the ones who come here asking for help don't plan on sticking for long so they obviously don't care.

One way we can make them learn is by letting them know that without code tags there is no hope for getting any help...

Re: Switch Statement with String

Bench has given a good suggestion. But if you are not allowed to use maps, try using two parallel string arrays in which the location of the name of the animal and its description resides in the same location in their respective arrays.

const int SIZE = 3;
string animal[SIZE] = {"dog", "cat", "pig"};
string desc[SIZE] = {"bark", "meow", "oink"};

bool found = false;
for(int i = 0; i < SIZE; ++i)
{
    if(animal[i] == input)
    {
        cout << animal[i] << " -> " << desc[i];
        found = true;
        break;
    }
}
if(!found)
    cout << "No such animal exists";

I know this looks like a lot of work for a single user input, but is just another way of doing things, plus this is much more flexible approach instead of the hard-coded 'if...else' or 'switch' constructs. Since you are under going a programming course, I guess the focus would be more on logic and uniqueness than efficiency.

Re: Permutation

Dump the loops, what you need is a recursive algorithm which would work for arbitrary lengths of arrays. One of the way is using 'Heap Permute'. Here is a sample program which you can easily adapt to use with C style strings:

// Untested

const int SIZE = 4;
static int counter = 1;

void swap(int arr[], int one, int two)
{
    int tmp = arr[one];
    arr[one] = arr[two];
    arr[two] = tmp;
}

void print(int arr[])
{
    for(int i = 0; i < SIZE; ++i)
    {
        cout << arr[i] << "  ";
    }
    cout << " ------->  " << counter++;
    putchar('\n');
}

void permute(int arr[], int size)
{
    if(size == 1)
    {
        print(arr);
    }
    else
    {
        for(int i = 0; i < size; ++i)
        {
            permute(arr, size - 1);
            if(size % 2 == 1)
                swap(arr, 0, size - 1);
            else
                swap(arr, i, size - 1);
        }
    }
}

int main()
{
    int myArr[SIZE] = {1, 2, 3, 4};
    permute(myArr, SIZE);

The 'onunload' event fires before the browser is closed and if an alert is fired, stops the window from closing so 'closes so quickly' is not an issue as such. The problem here is that the OP wants a function which would be fired _if and only if_ the browser is closed which I don't think is possible using any standard way.

Re: display:block to show a table?

Yes, the visibility property works cross browser. But the catch here is that when the visibility is set to 'hidden', the element is still present there and still contributes to the layout of the page, it just isn't visible.

On the other hand, setting the display property to nothing('') will remove the element and effect the layout of the page since the element is physically not there (though I guess it exists in the DOM since we can always make it come back).

Choose the method which suits you the most in the given scenario keeping the above things in mind. Here is an interesting read.

Re: Help needed in graphics.h

Every object you create can have a draw method, which will know how to render itself on the screen. So you just need to call the draw method of each object in a loop for all objects in the game. The object will have its own information like color, position etc. so you don't need to worry about the location of drawing.

No, that won't work. Destruction of a class object has got nothing to do with the display. You would anyways need to actually 'erase' the thing which is on the screen. Thus your logic would consist of two parts: Game logic and graphics.

When the pawn is moved, you need to call the move() function on the object as well as repaint the screen instead of just destroying the object.

Re: Help needed in graphics.h

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);

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.
