I've tried this it worked in part, since the dots wont get smaller there are just a lot of big dots

I was looking at a page called Javascript: Convert Strings to Binary (and representing in a nerdy way!) where you can convert a String into binary dots using Javascript and I loved that, but how I can do that? Since the code isn't for making that grid...

Hello,
My friend gave me a code to try a bit. What it does is that it gets a text and format it. Here it is:

function boldAndItalicize(text) {
  return text.replace(/&/g, '&').replace(/</g, '<')
      .replace(/(\*+)([^*]{1,1024})(\*+)/g,
               function (whole, open, content, close) {
                 if (open.length === close.length) {
                   switch (open.length) {
                     case 1: return '<i>' + content + '</i>';
                     case 2: return '<b>' + content + '</b>';
                   }
                 }
                 return whole;
               });
}

But I want to know how I could input a plain text file(like test.txt , that is on the same folder as the script) in the text parameter?

I'm still not seeing a "getString()" method for TextField, or setString(), either. getText() and setText(), yes, but not getString or setString.
This shouldn't be your problem - calling non-existent methods doesn't throw an NPE.
To get this exception, your textBox3 must be null.
Put in this line before the call to textBox3 to test this:

System.out.println("textBox3 "+textBox3==null?"is":"is not"+"null");

Now I got this:

is notnull
TRACE: <at java.lang.OutOfMemoryError>, Exception caught in Display class
java.lang.OutOfMemoryError
   (stack trace incomplete)

textField is the name of the class, and the type is a TextField , remember that I'm at J2ME

Yes, I was asking if the textField is JTextField, because there is no getString() function for a JTextField. Where you call textField.getString(), are you sure there is a value received from this? Put a System.out.println(textField.getString()) before you initialise test.

textField has text entered :)

String test = null? If you want to create an empty string use String test = ""; Not sure if that's where your problem lies.

textField.getString()

Is this a JTextField?

This is what I got now:

Line 130 Is the last one:

String test = null;
        test = "tst" + textField.getString() + "test";
        textBox3.setString(test);

Hello,
I'm building a program that gets the value of a TextField, concatenate with some other Strings and then display them on a TextBox when the ScreenCommand is clicked, the problem is that it's calling a NullPointerException. My code is like this(of course it has a lot more stuff):

/* .... */
        } else if (command == submitCommand) {
            FirstPart();
            // write pre-action user code here
            switchDisplayable(null, getTextBox3());
            // write post-action user code here
        }
/* .... */

public void FirstPart() {
    String test = null;
    test = "tst" + textField.getString() + "test";
    textBox3.setString(test);
}
/* .... */

And I get this when I click the menu:

TRACE: <at java.lang.NullPointerException:   0>, Exception caught in Display class
java.lang.NullPointerException:   0

        at com.sun.midp.events.EventQueue.run(), bci=179

What should I do to correct this?

*PS: Netbeans should have a `NullPointerException` corrector tool :P*

I'm trying to adapt the opensource code from the page Drag and Drop in MobileSafari, here is a snippet of the code I've changed from:

function jsonFlickrApi(data) {
		for (var i = 0; i < data.photos.photo.length; i++) {
			var p = data.photos.photo[i],
				img = document.createElement("img");
			img.src = 'http://farm'+p.farm+'.static.flickr.com/'+p.server+'/'+p.id+'_'+p.secret+'_m.jpg';
			img.className = "movable";
			img.xfmTX = Math.random()*(window.innerWidth-240);
			img.xfmTY = Math.random()*(window.innerHeig?        ndom()*(wsndo>b-his).hide();
                });
                // to w.Damg.Uidiv>

I don't know how to do this in Tasm, but i wrote a article at CodeProject some time ago using MASM32, take a look: http://www.codeproject.com/KB/DLL/intro_to_dlls_in_masm.aspx

Hope this helps!

Hello,
I'm learning C# and i want to know how i can add a item in a ListBox like this, the user click in a button, then it creates a item in the ListBox and in the ListBox the user digits what he want in that field, when the user want to edit it he only double click in the item and he edits that value, but i don't know how to do this.

Nooooooooo!
Now DaniWeb is like StackOverflow! :(
With this reputation!

Hello,
I use Nasm as my default Assembler, but with a couple days i was testing MASM and now i want to know how many users here use this Assembler.

Thanks,

Thanks very much reganstar!

Hello,
I'm a brazilian, but my friend is chinese and he buyed a notebook here in Brazil(Don't have chinese support installed) and my Windows XP CD don't have all that files to install the language pack, then how i can get the language pack?

Thanks,

Hello,
I'm starting in the development under PocketC and i want to know if here in DaniWeb we have other users that are using the same software.

Nathan Paulino Campos

In my opinion C# is a C++, but like Java and .Net because you can only develop using it are all shareware.

Thanks!

Hahahhahahahaha!

It's time to decide!
In a couple of time i will be back with the answer!

stdafx.h in Visual Studio, have to be included on the project don't matter, but it have to be there!

Planing ahead is my forte, but first i have to try both and i do this at this time!

Please, i need to decide this today, and in only 2 hours!!!

Hahahahahhaha!
Very nice Matty!

I'm learning to use the Microsoft Visual Studio and i hate this stdafx.h header!

GNU is better in my opinion!

Don't use <pre> and </pre>!, use the code tags: [ code=cplusplus ]...[ /code ], without spaces!

Thanks!

Because i hate .Net and C#, in my opinion!
And C is much more like C++, than if i go to develop on it will be more easy to learn!

Thanks!

Other things, please put better descriptions as Salem says and this isn't the right forum to talk about C, use the C forum here in DaniWeb!

Thanks!

Hello,
At this times i need to decide something that will chage my life forever, it is: Continue with C++ and the possibility to compile my programs at my HP Jornada 720(Handheld PC) and in my PC only and NOT for my j720, or learn C and start my mobile development carrer with eVC++(One of my dreams). What i choose?

Thanks,

Hello,
Because of my new and the most of the future projects, i'm needing to learn C and use Windows, but because of this, i don't know how to use the Windows API, then i'm asking for an example of using DeleteFile function.

Thanks,
Nathan Paulino Campos

Put the code tags!

Thanks!

Hello,
I'm trying to download the binarys of the FPC ver. 2.1.2 Win32, because i need to develop a program that i only can compile it in this version of FPC, then if you have the binary of this version of a link to it i will be very happy.

Thanks,
Nathan Paulino Campos

That's good!, a site for our classes!

Very nice!

Don't put this dirty words in your title, put better titles and that explain what you need!

Thanks!

And just another thing: Please put better titles, like: Trying to build a record app, Help in Records...
It's better ad more organized.

Huh, it's hidden, now i understand!

XAMP is very nice!
See this two links:
- Documentation About XAMP
- IBM - Install XAMP

Hope it helps!

I approve your opinion!
You never know!

Thanks very much!!!!!!!!

huh!!!!

Huh, now i'm thinking the same!

If you're on Windows, you can write a program that adds the association on the Windows registry, it's the most easy way!

That's very nice alishujahx!
I can see the class and just one more thing: Congratulation for your very very nice idea!

Congratulations!!!!!

See here my console log:

ubuntu@eeepc:~$ g++ -IB:/home/ubuntu/.zlib/include comp.cpp -LB:/home/ubuntu/.zlib/lib -llibz
/usr/bin/ld: cannot find -llibz
collect2: ld returned 1 exit status
ubuntu@eeepc:~$

And if i try zlib:

ubuntu@eeepc:~$ g++ -IB:/home/ubuntu/.zlib/include comp.cpp -LB:/home/ubuntu/.zlib/lib -lzlib
/usr/bin/ld: cannot find -lzlib
collect2: ld returned 1 exit status
ubuntu@eeepc:~$

I tryed this two modes, because the lib file name is libz.a

Only one question more: You can compile this in your compiler?

Thanks,
Nathan Paulino Campos

I'm in Brazil, but my time that i can view the lessons are about 2:30 pm to 10 pm in Brazil, that haves the timezone GMT -3.

Thanks!

It's VOIP technology, it's like an telephone, but for internet!

It's very simple to use, is like the others IMs, but it's better for Voice and Video chat!

Tom Gunn is right, and another thing, please put the code highlighting, like this: [ code=cplusplus ] ... [ /code ], but without spaces.

Thanks!

I'm going o add you, my Skype is ubuntu-nathan, if someone want to add me too, i will be very happy, but remember that i'm learning C++.

Thanks For The Future Help!

Hello,
I'm learning C++ and trying to build my own file zipper, because i like very much to work with zip files, but now i want to build my own zipper and it's so hard to find good resources to start. As you can see in my previous posts i was trying to correct the only code snippet that i've founded in Google, but it's getting so much errors.

Then the only thing that i want is a very good snippet to start my zipper, remember that i want to build a zipper, not an unzipper.

Thanks,
Nathan Paulino Campos

Thanks codejoust, i'm starting and i don't know much things about how to search for gems, you can post a good site to search for gems, because i do a search in Google and i didn't get any good sources.

Thanks!
