  • Dynamically resizing CFWINDOW to fit content

    - by Ryan French
    Hi all, Am currently working on a site that uses a lot of cfwindow objects and I was wondering if anyone knows of a way to dynamically resize the window so that all the content fits in without the need for scroll bars. I have tried using the overflow=visible configuration but it doesnt seem to make a difference. Thanks in advance for any advice.

  • null pointer exception on list.add

    - by Eric
    I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

  • Is it okay to rely on javascript for menu layout?

    - by Ryan
    I have a website template where I do not know the number of menu items or the size of the menu items that will be required. The js below works exactly the way I want it to, however this is the most js I've every written. Are there any disadvantages or potential problems with this method that I'm not aware of because I'm a js beginner? I'm currently manually setting the padding for each site. Thank you! var width_of_text = 0; var number_of_li = 0; // measure the width of each <li> and add it to the total with, increment li counter $('li').each(function() { width_of_text += $(this).width(); number_of_li++; }); // calculate the space between <li>'s so the space is equal var padding = Math.floor((900 - width_of_text)/(number_of_li - 1)); // add the padding the all but the first <li> $('li').each(function(index) { if (index !== 0) { $(this).css("padding-left", padding); } });

  • How can I strip line breaks from my XML with XSLT?

    - by Eric
    I have this XSLT: <xsl:strip-space elements="*" /> <xsl:template match="math"> <img class="math"> <xsl:attribute name="src">http://latex.codecogs.com/gif.latex?<xsl:value-of select="text()" /></xsl:attribute> </img> </xsl:template> Which is being applied to this XML (notice the line break): <math>\text{average} = \alpha \times \text{data} + (1-\alpha) \times \text{average}</math> Unfortunately, the transform creates this: <img class="math" src="http://latex.codecogs.com/gif.latex?\text{average} = \alpha \times \text{data} + (1-\alpha) \times&#10;&#9;&#9;&#9;&#9;&#9;\text{average}" /> Notice the whitespace character literals. Although it works, it's awfully messy. How can I prevent this?

  • Where's the rest of the space used in this table?

    - by Eric H.
    I'm using SQL Server 2005. I have a table whose row size should be 124 bytes. It's all ints or floats, no NULL columns (so everything is fixed width). There is only one index, clustered. The fill factor is 0. After inserting a ton of data, sp_spaceused returns the following name rows reserved data index_size unused OHLC_Bar_Trl 117076054 29807664 KB 29711624 KB 92344 KB 3696 KB which shows a rowsize of approx (29807664*1024)/117076054 = 260 bytes/row. Where's the rest of the space? Is there some DBCC command I need to run to tighten up this table (I could not insert the rows in correct index order, so maybe it's just internal fragmentation)?

  • AppEngine GeoPt Data Upload

    - by Eric Landry
    I'm writing a GAE app in Java and only using Python for the data upload. I'm trying to import a CSV file that looks like this: POSTAL_CODE_ID,PostalCode,City,Province,ProvinceCode,CityType,Latitude,Longitude 1,A0E2Z0,Monkstown,Newfoundland,NL,D,47.150300000000001,-55.299500000000002 I was able to import this file in my datastore if I import Latitude and Longitude as floats, but I'm having trouble figuring out how to import lat and lng as a GeoPt. Here is my loader.py file: import datetime from google.appengine.ext import db from google.appengine.tools import bulkloader class PostalCode(db.Model): id = db.IntegerProperty() postal_code = db.PostalAddressProperty() city = db.StringProperty() province = db.StringProperty() province_code = db.StringProperty() city_type = db.StringProperty() lat = db.FloatProperty() lng = db.FloatProperty() class PostalCodeLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'PostalCode', [('id', int), ('postal_code', str), ('city', str), ('province', str), ('province_code', str), ('city_type', str), ('lat', float), ('lng', float) ]) loaders = [PostalCodeLoader] I think that the two db.FloatProperty() lines should be replaced with a db.GeoPtProperty(), but that's where my trail ends. I'm very new to Python so any help would be greatly appreciated.

  • MS Access raise form events programmatically

    - by Eric G
    Is it possible to raise built-in MS Access form events programmatically? I have a feeling it isn't but thought I would check. (I am using Access 2003). For instance, I want to do something like this within a private sub on the form: RaiseEvent Delete(Cancel) and have it trigger the Access.Form delete event -- i.e. without actually deleting a bound record. Note my delete event is not handled by the form itself but by an external class, so I can't simply call Form_Delete(Cancel).

  • How Can I Set Up a "Where" Statement with a PHP Array

    - by Ryan
    Am I able to apply "where" statements to PHP arrays, similar to how I would be able to apply a "where" statement to a MySQL query? For example, suppose I have the following array: $recordset = array( array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 1, 'clicks' => 123, 'users' => 4), array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 2, 'clicks' => 134, 'users' => 5), array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 3, 'clicks' => 341, 'users' => 2), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 1, 'clicks' => 113, 'users' => 4), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 2, 'clicks' => 234, 'users' => 5), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 3, 'clicks' => 421, 'users' => 2), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 4, 'clicks' => 22, 'users' => 3), array('host' => 2, 'country' => 'es', 'year' => 2010, 'month' => 1, 'clicks' => 111, 'users' => 2), array('host' => 2, 'country' => 'es', 'year' => 2010, 'month' => 2, 'clicks' => 2, 'users' => 4), array('host' => 3, 'country' => 'es', 'year' => 2010, 'month' => 3, 'clicks' => 34, 'users' => 2), array('host' => 3, 'country' => 'es', 'year' => 2010, 'month' => 4, 'clicks' => 1, 'users' => 1),); How can I limit the output to only show the keys and values related to 'host' 1 and 'country' fr? Any help would be great.

  • How would I write a virtual CD/DVD burner that would allow programs that burn to write to ISO?

    - by Ryan
    I want to write an app that will allow a program like iTunes which normally will recognize a DVD/CD burner to recognize a virtual one and then write to it creating an ISO. I would guess to use C/C++... can someone point me in the right direction as to how this can be done? Basically it would be a virtual CD/DVD burner that would output an ISO file to the hard drive. I want to do this for both the usefulness of it as well as the challenge, just need an idea of how to approach it, have no idea how to write virtual hardware.

  • Why aren't my JQuery .ajax requests being made in parallel?

    - by Ryan Olson
    I am trying to make two ajax requests in parallel using jQuery like this: var sources = ["source1", "source2"]; $(sources).each(function() { var source = this; $.ajax({ async: true, type: "POST", data: {post: "data", in: "here"}, url: "/my/url/" + source, success: function(data) { process_result(data); } }); }); I got the basic structure from this question, but my requests still aren't being made in parallel. "source1" takes a while to complete, and I can see on the server that the second request isn't made until the first is completed. As far as I can tell, I don't have any other active requests, so I don't think it's a problem with the maximum number of parallel requests for the browser. Am I missing something else here?

  • Printing python tkinter output

    - by Eric
    I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

  • Comments for Function in Emacs

    - by Ryan
    I'm looking for a way to add comments for my functions in Emacs. Of course doxymacs is a nice candidate. But I prefer another way works without the necessary libs. Can anyone recommend some others ways for adding smart comments for functions in Emacs? Thanks. Edit: Now I found this: http://nschum.de/src/emacs/doc-mode/, but it seems that it does not work well after I require it into my .emacs and add hook for js-mode. Doesn't it support js functions ?

  • What is the most efficient way to use Core Data?

    - by Eric
    I'm developing an iPad application using Core Data, and was hoping someone could clarify something about Core Data. Right now, I populate my table by making a fetch request for all of my data in viewDidLoad. I'd rather make individual fetch requests in my tableView:cellForRowAtIndexPath:. Can anyone tell me which is more efficient, and why? In other words, is it much less efficient to make lots of small requests as opposed to one big request?

  • How can I make XSLT work in chrome?

    - by Eric
    I have an XML document here that is served with a corresponding XSL file. The transformation is left to be executed client-side, without JavaScript. This works fine in IE (shock horror), but in Google Chrome, just displays the document's text nodes. I know that it is possible to do client-side XSL in Chrome, as I have seen examples of it, but I am yet to be able to replicate this success myself What am I doing wrong?

  • Multiple ID's in database

    - by eric
    I have a database that contains a few tables such as person, staff, member, and supporter. The person table contains information about every staff, member, and supporter. The information it contains is name,address,email, and telephone. I also created an id that is the primary key. My issue is that I also have an primary key ID for staff, member, and supporter. For instance, in the person table is John with id 1. He is a supporter so in the supporter table is pID(for person id)to reference back to John with all his information and ID(for supporter ID). pID references to the person table and every person has an ID incremented by 1 starting at 1. supporter ID is for every supporter and also starts at 1 and is incremented by 1. Is it possible to have in the supporter table pID = 1 and supporter ID = 1? Another person may have a pID = 26 and supporter ID = 5. Or will supporter ID have to be different than the pID and be something like "sup"? So you would have pID = 1 and supporter ID = sup1 or pID = 26 and supporter ID = sup5

  • Extend Google AppEngine User in JRuby?

    - by Ryan Montgomery
    I'm working with JRuby and DataMapper running on Google AppEngine. I want to add a property to the AppEngine::User like :active_calendar which is a reference to a Calendar kind. I was able to do something in Python this way using a back reference. Are these possible in JRuby? Is this possible? Do I need to subclass the User? Can I even do that? If so - how? Thanks!

  • Need one login for two different sites

    - by Eric
    I am tasked to create a web site using Django. It will be a 'sister' site to an existing Plone site. The same Apache instance will be the front end to the sites which allows me to use the same domain name. However, the owners want the users to be able to log into one and still be logged into the other one. How can this be accomplished? Thanks! :)

  • How do I tell Entity Framework that a column in a view is nullable?

    - by Ryan ONeill
    I have a view which has an Int column which is nullable (let's call it StackOverflowCount). When generating an EF model from the database, the EF designer does not recognise it as nullable and creates the column as an Int. The issue I have is that on the EF designer I have set the column to Nullable and the following error then kills the compilation; Error 3031: Problem in mapping fragments starting at line 2327: Non-nullable column MyView.StackOverflowCount in table MyView is mapped to a nullable entity property. I can get round this by opening the .edmx file in XML mode and manually editing the SQL column definition, but there is no way to do this using the designer and it gets overwritten the next time I refresh from the model from the DB. Is this 'by design' or an example of something that slipped through into EF 4.0? I'm using .Net 4.0 with EF 4.0 under VS 2010.

  • Help me understand why page sizes are a power of 2?

    - by eric
    Answer I need help with is: Recall that paging is implemented by breaking up an address into a page and offset number. It is most efficient to break the address into X page bits and Y offset bits, rather than perform arithmetic on the address to calculate the page number and offset. Because each bit position represents a power of 2, splitting an address between bits results in a page size that is a power of 2. i don't quite understand this answer, can anyone give a simpler explanation?

  • Forking Public GitHub Code that is also Sold as a Complied App

    - by Ryan Castillo
    I found a public repo on GitHub that I would like to play around with. I can see myself potentially spending a lot of time writing tests for it and expanding its functionality. The code is also being sold as an app. I have no problem with this because I admire the owner's practice of sharing his source and also providing the convenience of paying for the app for users who don't want to mess with compiling it. If I was to spend time with this code as a separate fork what would prevent the owner from merging it with his master branch? Is it ethical for him to still profit off of my added functionality? Should a line be drawn somewhere?
