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.

Good point, I missed that one. But considering there are no attributes having the name 'name' in the global namespace (window), there is no harm as such. I for one, don't prefer using such names as my variable names.

Re: Parent/Child Windows

Your code does not run because you ignore the important aspects of the code posted by me. You have a global variable called 'name' and at the same time have a local variable 'name'. Because of this the local one hides the global one. Change the name of the function variable to something else than 'name'.

The second mistake you make is of not assigning the reference of the newly opened window to the variable 'name'. See my previous example for more info and post your code if it still doesn't work.

Re: Parent/Child Windows

When the button is clicked, check to see if the window is already open using the 'window.closed' property which returns a boolean. If the child window is open, just give it the focus using the function 'focus()' and if it isn't then open a new one.

<html>
<head>
    <script>
    var wnd = null;
    function openit()
    {
        if(!wnd || wnd.closed)
            wnd = window.open("http://www.google.com");    
        else
            wnd.focus();
    }

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.

Your class design looks weird, but I will leave that up to you to figure out.

I disagree. I absolutely refuse to add code tags to posts of those members who have been already warned a number of times. Maybe you have a lot of time firing up your favorite IDE, indenting it and reposting it -- many don't.

> Newbies should not be blamed for their stupidity.
Stupidity yes, casualness and carelessness no. And come to think of it, this thread has been started keeping exactly these kind of people in mind who never bother using code tags.

> We don't want to ignore them, we want to help them.
Help begets help. If someone ignores me repeatedly, I would probably do the same.

And last but not the least, I completely am in favor of a script which reminds the newbies to use code tags along with the link to the page which shows how to use code tags. Considering that they won't be able to make their post, they would definitely consider reading the announcements more carefully. But considering most people block scripts from sites, a client side script won't do the job...

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.

Re: XY Coordinate

Implementation of instance methods should occur only once -- either in the header file or the cpp file. The error message say it all : you are providing a definition of your instance methods in both the header file as well as the cpp file.

The structure of a normal project is:
• MyClass.h (the class declaration, containing the function prototypes)
• MyClass.cpp (the class definition, containing the implementation)
• Driver.cpp (the program which uses MyClass and other classes, normally the entry point of program)

So just remove the function definition from the header files keeping only the declaration. Also it doesn't make sense to keep a header file if all you are going to do is implement the methods there itself.

And BTW, its #include <cmath> and not #include <math.h>

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. Come to think of it, most of them don't even know what infractions or warnings are !!!

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