Netbeans GUI Form corrupted?

- by hubpages-my

I was making a java gui application through netbeans IDE. All was working fine but yesterday when I opened the form in Netbeans, it said that the form had been corrupted and it could only open that form in read-only mode. When I opened that form in read-only mode, I found that the code was incomplete as severals lines of coding wasn't there at the end. Could anybody tell me how to recover the form. The form is perfect in lookwise but the generated code is incomplete. The code is too long to write it again. The Netbeans told me to get help from http://wiki.netbeans.org/FormGuardedBlockError but I didn't find any helpful information there.

Turn Bluetooth On and Off in Andriod 1.5 (SDK level 3)?

- by pcm2a

There are tons of pay and free bluetooth toggles on the market that work with Android 1.5 (SDK level 3). The problem is there is no visible API for this! Does anyone have any working code snippits on how to enable and disable bluetooth that works on Android 1.5? I assume you must have to use some kind of reflection for it. There are some examples over on anddev.org, but they only work with Android 1.1 or lower. This is for Android 1.5 (SDK level 3) and not Android 2.0 or greater. In Android 2.0 or later Google added easy to use APIs.

Create a Sin wave line with Processing

- by Nintari

Hey everybody, first post here, and probably an easy one. I've got the code from Processing's reference site: float a = 0.0; float inc = TWO_PI/25.0; for(int i=0; i<100; i=i+4) { line(i, 50, i, 50+sin(a)*40.0); a = a + inc; } http://processing.org/reference/sin_.html However, what I need is a line that follows the curve of a Sin wave, not lines representing points along the curve and ending at the 0 axis. So basically I need to draw an "S" shape with a sin wave equation. Can someone run me through how to do this? Thank you in advance, -Askee

Problem with CSS DIV align

- by Sergio

If the doctype declaration is <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 TRANSITIONAL//EN"> what is the best way for horizontal alignment of the DIV's like these: <div id="outer"><div id="inner">Some text</div></div> The CSS is: #outer{ border-top:1px dotted #999; background-color: #F4F4F4; width:100%;} #inner{ width:500px;border:1px solid #F00; margin:auto;} The thing that I want to do is the inner DIV align at center (horizontally) inside the outer DIV. This CSS working fine if the doctype declaration is <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

How do I set sys.excepthook to invoke pdb globally in python?

- by saffsd

From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.

What, if any, is wrong with this definition of letrec in Scheme?

- by Lajla

R5RS gives proposed macro definitions for library forms of syntax: http://schemers.org/Documents/Standards/R5RS/HTML/r5rs-Z-H-10.html#%_sec_7.3 Which also defines letrec, in a very complicated way, certainly not how I would define it, I would simply use: (define-syntax letrec2 (syntax-rules () ((letrec2 ((name val) ...) body bodies ...) ((lambda () (define name val) ... body bodies ...))))) As far as I understand the semantics of letrec, which I use very often as a named let. It works in this way, however as I've had my fair share of debates with philosophers who think they can just disprove special relativity or established phonological theories, I know that when you think you have a simple solution to a complex problem, it's probably WRONG. There has got to be some point where this macro does not satify the semantics of letrec else they'd probably have used it. In this definition, the definitions are local to the body of the letrec, they can refer to each other for mutual recursion, I'm not quite sure what (if any) is wrong.

Am i missing something is a JMS topic implemented as a queue ?

How can I get my setup.py to use a relative path to my files?

- by Chris B.

I'm trying to build a Python distribution with distutils. Unfortunately, my directory structure looks like this: /code /mypackage __init__.py file1.py file2.py /subpackage __init__.py /build setup.py Here's my setup.py file: from distutils.core import setup setup( name = 'MyPackage', description = 'This is my package', packages = ['mypackage', 'mypackage.subpackage'], package_dir = { 'mypackage' : '../mypackage' }, version = '1', url = 'http://www.mypackage.org/', author = 'Me', author_email = '[email protected]', ) When I run python setup.py sdist it correctly generates the manifest file, but doesn't include my source files in the distribution. Apparently, it creates a directory to contain the source files (i.e. mypackage1) then copies each of the source files to mypackage1/../mypackage which puts them outside of the distribution. How can I correct this, without forcing my directory structure to conform to what distutils expects?

Which svn client to install on Windows 7 machine?

- by user246114

I just got a new PC running Windows 7 (64-bit). I'd like to install an SVN client (command line only, I don't want TortoiseSVN). I'm not sure which of these to install: http://subversion.apache.org/packages.html#windows does anyone have any opinions on this? I tried going for the ones hosted by Tigris, but the downloaded zip says to read an install file hosted at their site, but the link is broken. Do we simply download, then call svn.exe as needed, no need for a real 'install'?

Valid Email Addresses - XSS and SQL Injection

- by PAAMAYIM_NEKUDOTAYIM

Since there are so many valid characters for email addresses, are there any valid email addresses that can in themselves be XSS attacks or SQL injections? I couldn't find any information on this on the web. The local-part of the e-mail address may use any of these ASCII characters: Uppercase and lowercase English letters (a–z, A–Z) Digits 0 to 9 Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~ Character . (dot, period, full stop) provided that it is not the last character, and provided also that it does not appear two or more times consecutively (e.g. [email protected]). http://en.wikipedia.org/wiki/E-mail_address#RFC_specification I'm not asking how to prevent these attacks (I'm already using parametrized queries and HTML purifier), this is more a proof-of-concept. The first thing that came to mind was 'OR [email protected], except that spaces are not allowed. Do all SQL injections require spaces?

Transform PDF to HTML, keep layout

- by Tgr

What methods are there to transform a PDF to HTML? It could be anything - online service, software, library. (Opensource preferred. In the last case, php or python would be preferred.) It has to keep the original layout (including page numbers, footnotes and such), keep the images (combining them to one single background image per page is acceptable) and keep the links. It should preferably output valid XHTML and clean up PDF features such as ligatures, but if there is some post-processing required, I can live with that. Something with a clean, relatively semantic HTML output would be great. The closest one I found was zamzar.org, but it choked on links. (Also, the HTML output is an ugly heap of absolutely positioned divs and needs post-processing because of encoding problems.)

WCF: connecting to service over internet times out

- by Shaul

Still on the WCF learning curve: I've set up a self-hosted WCF Service (WSDualHttpBinding), which works fine on my own computer, which resides behind a firewall. If I run the client on my own computer, everything works great. Now I installed the client on a computer outside my network, and I'm trying to access the service via a dynamic DNS, like so: http://mydomain.dyndns.org:8000/MyService. My port forwarding issues were taken care of in a previous question; I can now see the service is up in my browser. But now when I try to run the client on the other machine, I get the following error message: "The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout." I have disabled security on the service, so that's not it. What else might be preventing the connection from happening?

How to tell process id within Python

- by R S

Hey, I am working with a cluster system over linux (www.mosix.org) that allows me to run jobs and have the system run them on different computers. Jobs are run like so: mosrun ls & This will naturally create the process and run it on the background, returning the process id, like so: [1] 29199 Later it will return. I am writing a Python infrastructure that would run jobs and control them. For that I want to run jobs using the mosrun program as above, and save the process ID of the spawned process (29199 in this case). This naturally cannot be done using os.system or commands.getoutput, as the printed ID is not what the process prints to output... Any clues? Edit: Since the python script is only meant to initially run the script, the scripts need to run longer than the python shell. I guess it means the mosrun process cannot be the script's "son process". Any suggestions? Thanks

XNA .FBX Vertex Color Missing

- by Alex

When I vertex paint and export my models from Blender (or Maya) for use in my XNA 4.0 project, I somehow lose the vertex color channel for the model. I use no custom model object or content pipelines and my own shader throws me the error: The current vertex declaration does not include all the elements required by the current vertex shader. Color0 is missing. I tryed to reopen the model in other modeling tools and the vertex colors are there. What could cause the vertex color channel to not get loaded in XNA 4.0? Here's a temporary link to the FBX file(server refuses to send a fbx, so rename the .jpg file to .fbx after downloading) http://resources.gamestack.org/BananaBush.jpg

I want to use VI-like commands in Web Browser?

- by Frank

I love VI and I'm looking for a plugin of some sort that would allow me to input text in my browser (preferably Firefox or Chrome) using VI commands. It would save me an immense amount of time and at the same time when writing long emails. Can anyone think of any plugins that would allow me to do this? I was hopeful with Vimperator (https://addons.mozilla.org/en-US/firefox/addon/4891) but after installing it, I realized that it didn't do the one VI think I wanted to do: create or edit a text box with VI commands. It just allowed me to do Browser commands and scrolling in VI-style.

Seam-gen isn't working properly.. log4j acuses an error

Hello Seam Users, I'm having a couple problems with my Seam start up. I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class.

What preferred way to reconcile keyCode/charCode across browsers?

- by Drew Turner

Based on the properties of the keydown event I would like to ascertain what the current charCode are? Example. For the keydown event when the NumPad0, D0, and Colon key is pressed I would like to know what the associated charcode is. Currently I have a map that contains the charcode associated with that keyCode or use the current if charCode is not specified. keyCode = { Colon: 186, D0: 48, NumPad0: 96, }; charCodes = { 186: 59, 96: 48, }; shiftCharCodes = { 186: 58, 48: 41 }; Also in certain cases the keyCodes are different accross browsers? Example. The keydown event has different keyCode values across browsers. Colon Key (:/;) - keyCode is 59 on firefox - keyCode is 186 on IE/safari For more information http://www.quirksmode.org/js/keys.html
