  • Python: For loop problem

    - by James
    I have a PSP page with html embedded. I need to place another for loop so i can insert another %s next to background-color: which will instert a appropriate colour to colour in the html table. For example i need to insert for z in colours so it can loop over the colours list and insert the correct colour. Where ever i try to insert the for loop it doesnt seem to work it most commonly colours each cell in the table 60 times then moves onto the next cell and repeats itself and crashes my web browser. The colours are held in a table called colours. code below: <table> <% s = ''.join(aa[i] for i in table if i in aa) for i in range(0, len(s), 60): req.write('<tr><td><TT>%04d</td>' % (i+1)); for k in s[i:i+60]: req.write('<TT><td><TT><font style="background-color:">%s<font></td>' % (k)); req.write('</TT></tr>') #end %> </table>

  • Background Image w/Quartz Drawing

    - by James
    I'm using Quartz to do some basic drawing. I recently decided I wanted a background image for my app. So I went into my XIB file and added a UIImageView and set the background, looks good. However, when I run it, the Z-Index of the image is above my drawing. I googled a bit and found that you can do Layout Send to Back in IB...but that option is grayed out to me when I have my UIImageView selected. Is there an easy way to move this UIImageView permanently to the background? Is there perhaps an alternate method to doing this that I should consider? Thanks

  • Best way to determine variable type and treat each one differently in F#

    - by James Black
    I have a function that will create a select where clause, but right now everything has to be a string. I would like to look at the variable passed in and determine what type it is and then treat it properly. For example, numeric values don't have single quotes around them, option type will either be null or have some value and boolean will actually be zero or one. member self.BuildSelectWhereQuery (oldUser:'a) = let properties = List.zip oldUser.ToSqlValuesList sqlColumnList let init = false, new StringBuilder() let anyChange, (formatted:StringBuilder) = properties |> Seq.fold (fun (anyChange, sb) (oldVal, name) -> match(anyChange) with | true -> true, sb.AppendFormat(" AND {0} = '{1}'", name, oldVal) | _ -> true, sb.AppendFormat("{0} = '{1}'", name, oldVal) ) init formatted.ToString() Here is one entity: type CityType() = inherit BaseType() let mutable name = "" let mutable stateId = 0 member this.Name with get() = name and set restnameval=name <- restnameval member this.StateId with get() = stateId and set stateidval=stateId <- stateidval override this.ToSqlValuesList = [this.Name; this.StateId.ToString()] So, if name was some other value besides a string, or stateId can be optional, then I have two changes to make: How do I modify ToSqlValuesList to have the variable so I can tell the variable type? How do I change my select function to handle this? I am thinking that I need a new function does the processing, but what is the best FP way to do this, rather than using something like typeof?

  • Scrum stories and behind the scenes features

    - by James P.
    As I understand things, the Scrum backlog is composed of a series of Stories that represent something for the end user and this is further decomposed into Features. If this is the case, where does all the behind the scenes features go that aren't really linked to a story but are still useful? For example, say I'm making an application that catalogs the contents of a hard drive. A story wouldn't require it but having an md5 hash on each file would be a nice feature.

  • XML Parsing in Groovy strips attribute new lines

    - by Bill James
    I'm writing code where I retrieve XML from a web api, then parse that XML using Groovy. Unfortunately, it seems that both XmlParser and XmlSlurper for Groovy strip newline characters from the attributes of nodes when .text() is called. How can I get at the text of the attribute including the newlines? Sample code: def xmltest = ''' <snippet> <preSnippet att1="testatt1" code="This is line 1 This is line 2 This is line 3" > <lines count="10" /> </preSnippet> </snippet>''' def parsed = new XmlParser().parseText( xmltest ) println "Parsed" parsed.preSnippet.each { pre -> println pre.attribute('code'); } def slurped = new XmlSlurper().parseText( xmltest ) println "Slurped" slurped.children().each { preSnip -> println [email protected]() } the output of which is: Parsed This is line 1 This is line 2 This is line 3 Slurped This is line 1 This is line 2 This is line 3

  • How to have multiple instances of jQuery plugin on single page?

    - by James Skidmore
    I'm writing a simple jQuery plugin, but I'm having trouble being able to use multiple instances on a page. For instance, here is a sample plugin to illustrate my point: (function($) { $.fn.samplePlugin = function(options) { if (typeof foo != 'undefined') { alert('Already defined!'); } else { var foo = 'bar'; } }; })(jQuery); And then if I do this: $(document).ready(function(){ $('#myDiv').samplePlugin({}); // does nothing $('#myDiv2').samplePlugion({}); // alerts "Already defined!" }); This is obviously an over-simplified example to get across the point. So my question is, how do I have two separate instances of the plugin? I'd like to be able to use it across multiple instances on the same page. I'm guessing that part of the problem might be with defining the variables in a global scope. How can I define them unique to that instance of the plugin then? Thank you for your guidance!

  • Carbon, LSUIElement, and showing a window

    - by James Turner
    I have a Carbon LSUIElement application, which runs in the background (possibly with an icon in the menubar, depending on a pref) and occasionally needs to show a dialog to the user - sometimes in response to a user event, but sometimes in response to a background task failing or similar. (I'm using Qt 4.5, so the application is Carbon based; With Qt 4.6 things will be Cocoa based, but it sounds as if the problem may exist there too). The problem is that when I open a window, and show it, it doesn't get brought to the front. I assume this is an artefect of being an LSUIElement app. Qt uses SelectWindow in Carbon, and [makeKeyAndOrderFront] in Cocoa, to bring a window (and the app) to the front. To work around the problem, I tried going direct to the window server: (the first few steps are to get the WindowID, this will be simpler with Qt-Cocoa, since I can use NSWindow:nativeWindow) WindowRef ref = HIViewGetWindow((HIViewRef) aWidget->winId()); CGSWindow wid = GetNativeWindowFromWindowRef(ref); CGSConnection cid =_CGSDefaultConnection(); CGSOrderWindow(cid, wid, 1 /* above everything */, 0 /* NULL */); This works, sort of - the window comes to the front, but it's not highlighted or keyboard focused. Are there additional steps to fix those issues, or is there a simpler solution to the whole problem?

  • How can I perform a reverse string search in Excel without using VBA?

    - by e.James
    I have an Excel spreadsheet containing a list of strings. Each string is made up of several words, but the number of words in each string is different. Using built in Excel functions (no VBA), is there a way to isolate the last word in each string? Examples: Are you classified as human? - human? Negative, I am a meat popsicle - popsicle Aziz! Light! - Light!

  • How can I reference a drawable class in Android XML

    - by James Veenstra
    I've created a class that extends drawable that I'd like to reference inside a resource xml. I happen to need it in a selector, like so: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_window_focused="false" android:state_pressed="false" android:drawable="com.sample.android.contacts.TopBarCollapsed" /> <item android:state_window_focused="true" android:state_pressed="true" android:drawable="@drawable/top_switcher_collapsed_selected" /> <item android:state_focused="true" android:drawable="@drawable/top_switcher_collapsed_focused" /> com.sample.android.contacts.TopBarCollapsed is the class that extends drawable.

  • HelpSpot to Fogbugz to HelpSpot integration

    - by James Ludlow
    Does anyone have a nice example of integration between HelpSpot and Fogbugz? We're using HelpSpot as our customer facing software and ticket management, and then if a developer needs to work on a ticket the data will be pushed to Fogbugz. Obviously we can use the Fogbugz push API that Userscape provides, but this only allows you to specify the title of the incident in Fogbugz. Ideally I want to share title, assigned to, category and status in a two-way integration. Do most people just use emails between the two programs, or has anyone come across a nice third party app? Thanks in advance!

  • Read a specific range of lines from a file using c

    - by James Joy
    I have the following content in a file: hhasfghgsafjgfhgfhjf gashghfdgdfhgfhjasgfgfhsgfjdg jfshafghgfgfhfsghfgffsjgfj . . . . . startread hajshjsfhajfhjkashfjf hasjgfhgHGASFHGSHF hsafghfsaghgf . . . . . stopread . . . . . . jsfjhfhjgfsjhfgjhsajhdsa jhasjhsdabjhsagshaasgjasdhjk jkdsdsahghjdashjsfahjfsd I need to read the lines from the next line of startread till the previous line of stopread using a c code and store it to a string variable(of course with a \n for every line breaks). How can i achieve this? I have used fgets(line,sizeof(line),file); but it starts reading from the beginning. I don't have the exact line number to start and stop reading since the file is written by another C code. But there are these identifiers startread and stopread to identify whereto start reading. Operating platform is linux. Thanks in advance.

  • Nested Select in Rails

    - by James
    I am working on a Rails application which uses categories for items. My category model is self-joined so that categories can be nested: class Category < ActiveRecord::Base has_many :items # Self Join (categories can have subcategories) has_many :subcategories, :class_name => "Category", :foreign_key => "parent_id" belongs_to :parent, :class_name => "Category" ... end I have a form which allows a user to create an item which currently lists all categories in a select, but they are all listed together: <%= f.label :category_id %> <%= select :item, :category_id, Category.all.collect {|c| [ c.title, c.id ]} %> So the select looks something like this: Category1 Category2 Category3BelongsTo2 Category4BelongsTo1 But what I want is: Category1 - Category4BelongsTo1 Category2 - Category3BelongsTo2 Is there a helper for this (which would be awesome!)? If not, how could I accomplish this? Thanks!

  • How are attached properties useful in LINQ?

    - by James Cadd
    I got this question during an interview in the past and never really dug into in, but I've put some thought into it lately and I can't come up with a good answer. When I think of attached properties my mind goes straight to UI related concepts - what benefits could be had in using attached properties with LINQ? I'm starting to think the answer is "they're not" unless I find out otherwise!

  • Can I package my Eclipse extension so the right version is automatically installed?

    - by James
    Is there a way to build an Eclipse Update Site so that Eclipse 3.3 will install one version of my plug-in while Eclipse 3.4 will install another version? Background: I've become responsible for an Eclipse extension that has half a dozen plug-ins which depend on a "support" plug-in, and the support plug-in needs to be one version for Eclipse 3.3 and a different version for Eclipse 3.4/3.5. I currently have two separate features, "extension for 3.3" and "extension for 3.4+" but I'd like to not bother my users with this detail.

  • How to initialize F# list when size is unknown, using while..do loop

    - by James Black
    I have a function that will parse the results of a DataReader, and I don't know how many items are returned, so I want to use a while..do loop to iterate over the reader, and the outcome should be a list of a certain type. (fun(reader) -> [ while reader.Read() do new CityType(Id=(reader.GetInt32 0), Name=(reader.GetString 1), StateName=(reader.GetString 2)) ]) This is what I tried, but the warning I get is: This expression should have type 'unit', but has type 'CityType'. Use 'ignore' to discard the result of the expression, or 'let' to bind the result to a name. So what is the best way to iterate over a DataReader and create a list?

  • Live streaming using Flash

    - by James
    Hi, I was working on an application that streams live video using Flash client and Wowza media server. As of now, I use an independent desktop based encoder(Flash Media Live Encoder) to publish my live stream. I wanted to know if it is possible to do the encoding part in the browser? My application would be a used by many to publish their streams so I cannot ask everyone to use FMLE to publish. I was wondering how do the other web based video chat applications do the encoding part over the web. Please help. Thanks

  • Implicit vs explicit getters/setters in AS3, which to use and why?

    - by James
    Since the advent of AS3 I have been working like this: private var loggy:String; public function getLoggy ():String { return loggy; } public function setLoggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc... this.loggy = loggy; } and have avoided working like this: private var _loggy:String; public function get loggy ():String { return loggy; } public function set loggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc... this.loggy = loggy; } I have avoided using AS3's implicit getters/setters partly so that I can just start typing "get.." and content assist will give me a list of all my getters, and likewise for my setters. I also dislike underscores in my code which turned me off the implicit route. Another reason is that I prefer the feel of this: whateverObject.setLoggy( "loggy's awesome new value!" ); to this: whateverObject.loggy = "loggy's awesome new value!"; I feel that the former better reflects what is actually happening in the code. I am calling functions, not setting values directly. After installing Flash Builder and the great new plugin SourceMate ( which helps to get some of the useful features that FDT is famous into FB ) I realized that when I use SourceMate's "generate getters and setters" feature it automatically sets my code up using the implicit route: private var _loggy:String; public function get loggy ():String { return loggy; } public function set loggy ( loggy:String ):void { // do whatever is needed to check to make sure loggy is an acceptable value this.loggy = loggy; } I figure that these SourceMate people must know what they are doing or they wouldn't be writing workflow enhancement plugins for coding in AS3, so now I am questioning my ways. So my question to you is: Can anyone give me a good reason why I should give up my explicit g/s ways, start using the implicit technique, and embrace those stinky little _underscores for my private vars? Or back me up in my reasons for doing things the way that I do?

  • How do you unpack gems using jruby on rails 2.3?

    - by James Moore
    I'm trying to unpack all the system gems to end up with a standalone Rails directory including all the rails gems and all the system gems. I'm starting with a bare rails setup; just did a jruby -S rails and a 'generate jdbc'. I then add a config.gem 'jdbc-mysql' to environment.rb and do the jruby -S rake gems:unpack:dependencies. After unpacking, if I do a rake I get: no such file to load -- jdbc-mysql Is there something else you need to do to get the jdbc gem unpacked? I'm using jruby 1.4.0 (and moving to 1.5 is on my todo list) and rails 2.3.8.

  • A C# Refactoring Question...

    - by james lewis
    I came accross the following code today and I didn't like it. It's fairly obvious what it's doing but I'll add a little explanation here anyway: Basically it reads all the settings for an app from the DB and the iterates through all of them looking for the DB Version and the APP Version then sets some variables to the values in the DB (to be used later). I looked at it and thought it was a bit ugly - I don't like switch statements and I hate things that carry on iterating through a list once they're finished. So I decided to refactor it. My question to all of you is how would you refactor it? Or do you think it even needs refactoring at all? Here's the code: using (var sqlConnection = new SqlConnection(Lfepa.Itrs.Framework.Configuration.ConnectionString)) { sqlConnection.Open(); var dataTable = new DataTable("Settings"); var selectCommand = new SqlCommand(Lfepa.Itrs.Data.Database.Commands.dbo.SettingsSelAll, sqlConnection); var reader = selectCommand.ExecuteReader(); while (reader.Read()) { switch (reader[SettingKeyColumnName].ToString().ToUpper()) { case DatabaseVersionKey: DatabaseVersion = new Version(reader[SettingValueColumneName].ToString()); break; case ApplicationVersionKey: ApplicationVersion = new Version(reader[SettingValueColumneName].ToString()); break; default: break; } } if (DatabaseVersion == null) throw new ApplicationException("Colud not load Database Version Setting from the database."); if (ApplicationVersion == null) throw new ApplicationException("Colud not load Application Version Setting from the database."); }

  • How Do I Add Value To All Previous Values In Array

    - by James
    Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.

  • Is there a way to automate MS Office applications without license?

    - by james-h-l
    I am currently writing an application that will perform automation in Excel. I have MS Office (2007) installed on my work computer and the application is working fine referencing the the Microsoft Excel 12.0 Object Lirary. The target machine has the Office installed but not registered. It is one of those preinstalled editions. Attempting to run the application on the target machine I get an error saying Office is not installed? I'm assuming then you have to have a registed Office to use the object libraries? Is there anyway around this as I do not have a Office license key lying around and its quite expensive?

  • Storing date/times as UTC in database

    - by James
    I am storing date/times in the database as UTC and computing them inside my application back to local time based on the specific timezone. Say for example I have the following date/time: 01/04/2010 00:00 Say it is for a country e.g. UK which observes DST (Daylight Savings Time) and at this particular time we are in daylight savings. When I convert this date to UTC and store it in the database it is actually stored as: 31/03/2010 23:00 As the date would be adjusted -1 hours for DST. This works fine when your observing DST at time of submission. However, what happens when the clock is adjusted back? When I pull that date from the database and convert it to local time that particular datetime would be seen as 31/03/2009 23:00 when in reality it was processed as 01/04/2010 00:00. Correct me if I am wrong but isn't this a bit of a flaw when storing times as UTC? Example of Timezone conversion Basically what I am doing is storing the date/times of when information is being submitted to my system in order to allow users to do a range report. Here is how I am storing the date/times: public DateTime LocalDateTime(string timeZoneId) { var tzi = TimeZoneInfo.FindSystemTimeZoneById(timeZoneId); return TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, tzi).ToLocalTime(); } Storing as UTC: var localDateTime = LocalDateTime("AUS Eastern Standard Time"); WriteToDB(localDateTime.ToUniversalTime());
