• Graph spacing algorithm

  - by David

  Hi, I am looking for an algorithm that would be useful for determining x y coordinates for a number objects to display on screen. Each object can be related to another object and there can be any number of relationships and there can be any number of these objects. There is no restriction on the overall size of area on which to display these object. I am writing this in php and would be looking to store the coordinates in an array.

• indentation preference and personality

  - by dreftymac

  This question is similar in spirit to : http://stackoverflow.com/questions/492178/links-between-personality-types-and-language-technology-preferences But it is based specifically on indentation (spaces vs tabs and the number of spaces). The reason I am asking here instead of searching is because I remember seeing a specific document writing about this. If I remember correctly, it also talked about why Linus prefers eight spaces.

• How to connect to MS Access 2007, from Java on a mac

  - by aabrook

  I'm looking for a way to connect to a MS Access 2007 database from Java. I don't believe the ODBC way is available to me as I'm writing on a mac and will be pushing this product to Linux. The HXTT drivers also do not work with 2007. Is there a way, a tutorial, an example, etc that accomplishes this? Setting the connection as a JNDI Datasource is preferable but not required

• iPhone vertical toggle switch

  - by nan

  I'm trying to create a vertical toggle switch control for the iPhone (along the lines of UISwitch but vertical sliding). I was wondering whether an existing control already existed or if there are any good tutorials that explain the basics of creating custom controls for the iPhone. Currently I've tried using affine transforms to create the vertical switch from a basic UIswitch, and it works except that the slider is too small compared to the slider track, thus I'm looking for information on writing custom controls. Any direction is much appreciated.

  Basically I am writing a simple shopping cart. Each item can have multiple prices. (i.e. shirts where each size is priced differently). I would like to have a single price field in my admin panel, where when the first price is entered, an additional price field pops up. However I am kind of at a loss as to how to do this. What would be the best way to do this?

• Detect file creation date on iPhone OS?

  - by Greg Maletic

  I was planning on writing some code whose logic was based upon testing the creation date of a particular file in my app's Documents folder. Turns out, when I call -[NSFileManager attributesOfItemAtPath:error:], NSFileCreationDate isn't one of the provided attributes. Is there no way to discover a file's creation date? Thanks.

• Portable shebang line

  - by Mike

  #!/usr/bin/perl This is the shebang line to a lot of scripts I'm writing lately. Hard coding the path of the binary seems like it could create some problems. For instance, if one of my users has Perl installed at /something_else/bin then they'd have to change all the shebangs. I've seen some tools that will automatically replace the shebangs, but I'm wondering if there is something simpler.

• Is it better to create the db/tables programmatically or through a .db file in assets

  - by llappall

  Hi, does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets? What are the pros/cons of both approaches? I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste. Thoughts? Thanks! llappall

• Intercept tablet events and translate coordinates before any other application sees them

  - by superjoe30

  I'm writing a hack that sits in the system tray and corrects tablet pen input under very specific circumstances. I need to intercept only touch and pen input, test some conditions, and then translate the coordinates before the rest of the operating system sees the event. Is this possible? I'm willing to write a simple driver if I need to. Where should I begin?

• Design tools for creating skins for Flex 4 components

  - by user337965

  I'm looking for a tool to create just the skins for different kinds of Flex 4 components. Are there any? I'd like to be able to create the components myself and have the designer/artist do the skin, but I don't think they'd like the idea of doing them by writing MXML files.

• Preventing browser loading indicator with Chrome + GWT-rpc.

  - by Jeeyoung Kim

  Hello. I'm writing a ajax chatting webapp, just to test working with GWT. To simulate server side push of chat messages from the server to the browser, I have a XHR request running behind. It all works fine - except on Chrome, the browser is displaying a loading icon (a spinner) because of the XHR request on background. Is there any way to avoid this? I've tested it in Firefox, and it doesn't display such behavior.

• Silverlight RichTextBox Disable Mouse Selection

  - by Fastidious

  I am writing a custom control based on RichTextBox that needs the ability to process MouseLeftButtonDown events but must not allow user-initiated selection (I'm doing everything programmatically). I tried setting a flag in MouseLeftButtonDown to track dragging and then continuously setting the RichTextBox.Selection to nothing in the MouseMove event but the move event isn't fired until after I release the mouse button. Any ideas on how to solve this? Thanks.

• Example: Objective C method alongside a php method

  - by Nic Hubbard

  I am very used to javascript and php programing, and I just jumped into programing Objective C. After working with it for a few weeks, the methods still confused me, as to how it is passing params, and how the methods are named. Since I am used to php, I am used to seeing: function myFunc($param1, $param2, $param3, $param4) { return FALSE; } Could someone show me how this would be written in Objective C, so that I can get used to writing methods that have parameters?

• Java. Outside classes accessing protected methods.

  - by Jake

  Suppose I have a class in my package org.jake and it has a method with default access (no modifier). Then the method is visible inside the package only. However, when someone receives the jar of my framework, what is to stop them from writing a new class, declaring its package as org.jake, and using my supposedly invisible method? In other words, is there anything I can do to prevent them from doing that?
