• Source Control - XCode - Visual Studio 2005/2008 / 2010

  - by Mick Walker

  My apologies if this has been asked before, I wasnt quite sure if this question should be asked on a programming forum, as it more relates to programming environment than a particular technology, so please accept my (double) appologies if I am posting this in the wrong place, my logic in this case was if it effects the code I write, then this is the place for it. At home, I do a lot of my development on a Mac Pro, I do development for the Mac, iPhone and Windows on this machine (Xcode & Visual Studio - (multiple versions installed in bootcamp, but generally I run it via Parallels)). When visiting a client, I have a similar setup, but on my MacBook Pro. What I want is a source control solution to install on the Mac Pro, that will support both XCode and multiple versions of visual studio, so that when I visit a client, I can simply grab the latest copy from source control via the MacBook Pro. Whilst visiting the client, he / she may suggest changes, and minor ones I would tend to make on site, so I need the ability to merge any modified code back into the trunk of the project / solution when I return home. At the moment, I am using no source control at all, and rely on simply coping folders and overwriting them when I return from a client- thats my 'merge'!!! I was wondering if anyone had any ideas of a source provider I could use, which would support both Windows and Mac development environments, and is cheap (free would be better).

• How can I get the post text to be beside the avatar and not below it?

  - by William

  So I'm trying to create a forum with avatars, but right now the text is going below the avatars and not beside them. How can I fix this? Here is the CSS: .postbox{ text-align: left; margin: auto; background-color: #dbfef8; border: 1px solid #82FFCD; width: 100%; margin-top: 10px; } .postfooter{ width: 100%; border-top: 1px solid #82FFCD; } .postheader{ width: 100%; border-bottom: 1px solid #82FFCD; } .posttext{ width: 70%; text-align: left; border: 1px solid #82FFCD; } .postavi{ width: 20%; text-align: left; border: 1px solid #82FFCD; } and here is the html: <div class="postbox"><div class="postheader"> <b><span>CyanPrime!!~::##Admin##::~</span></b> </div> <div class="postavi"><img src="http://prime.programming-designs.com/test_forum/images/avatars/hacker.png" alt="hacker"/></div><div class="posttext">Let's test the Hacker Avatar.</div> <div class="postfooter"> [<a href="http://prime.programming-designs.com/test_forum/viewthread.php?thread=25">Reply</a>] 0 posts omitted. </div> </div>

• Binding WPF ComboBox in XAML - Why is it Empty?

  - by mdiehl13

  I am trying to learn how to bind my simple database (.sdf) to a combobox. I created a dataset with my tables in it. I then dragged a table from the DataSource onto my control. There are no build warnings/errors, and when it runs, the ComboBox is empty. <UserControl x:Class="OurFamilyFinances.TabItems.TransactionTab" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="414" d:DesignWidth="578" xmlns:my="clr-namespace:OurFamilyFinances" Loaded="UserControl_Loaded_1"> <UserControl.Resources> <my:FinancesDataDataSet x:Key="financesDataDataSet" /> <CollectionViewSource x:Key="accountViewSource" Source="{Binding Path=Account, Source={StaticResource financesDataDataSet}}" /> </UserControl.Resources> <Grid> <ComboBox DisplayMemberPath="Name" Height="23" HorizontalAlignment="Left" ItemsSource="{Binding Source={StaticResource accountViewSource}}" Margin="3,141,0,0" Name="accountComboBox" SelectedValuePath="ID" VerticalAlignment="Top" Width="120"> <ComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel /> </ItemsPanelTemplate> </ComboBox.ItemsPanel> </ComboBox> </Grid> The paths that is shows are correct, the selectedPath is "ID" and the displaypath is "Name". If I do this in Linq to Sql, the combo box does populate: this.accountComboBox.ItemsSource = from o in db.Account select new { o.ID, o.Name }; But I would like to learn how to do this in XAML. I have dragged datagrids from the DataSource as well, but they are not populated either. Any idea?

• Disadvantage of OOP?

  - by Bragaadeesh

  Typically i dont want to know the specifics of the cons of OOPs, but it felt kind of weird when I had an argument at an interview I attended recently. The question that was posted to me was to tell me one disadvantage of OOP (Object Oriented Programming). At that time, I felt OOP to be the most matured level of programming after the procedural/functional models. So I replied to him that I dont see any negatives at all. But the interviewer said there are few and I asked him to list one if he does not mind. He gave an example that I cant digest well, he said that OOP pattern does not strictly implement inheritance rules and cited the satellite/rocket example where the body parts will disintegrate periodically to remove weight during rocket launch and said that inheritance does not support this. His example kind of felt very weird to me the reason being the application of inheritance to this example. Then I left the example aside and I had this doubt - Can we unplug class hierarchies in such a manner (I am kind of confident in Java its not possible) in an ideal Object Oriented Design?

• py2app, pyObjc & macports compilation errors

  - by Neewok

  Hi, I'm currently writing a small python app that embeds cherrypy and django using py2app. It worked well until I tried to include pyobjc in my project, since my app needed a small GUI (which consists of a small icon in the top menu bar + a drop down menu). I can run my python script without any problem (I'm using python 2.6 with macports), but I can't launch the application bundle generated by py2app. A dialog box appears with the following message: ImportError: dlopen(/Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so, 2): no suitable image found. Did find: /Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so: mach-o, but wrong architecture I did a quick : sudo port -u install py26-pyobjc +universal but for some reason macports tries to build openssl, with which compilation fails each time. It seems the problem is related to zLib - this is what appears in the logs : :info:build ld: warning: in /opt/local/lib/libz.dylib, file is not of required architecture ...And here is the output of file /opt/local/lib/libz.dylib : /opt/local/lib/libz.dylib: Mach-O universal binary with 2 architectures /opt/local/lib/libz.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 /opt/local/lib/libz.dylib (for architecture i386): Mach-O dynamically linked shared library i386 Nothing looks wrong to me. I'm a bit stuck here. I don't even understand what openssl has to do with pyObjc, but it looks like I can't go anywhere if I don't manage to compile it. Macports really suck sometimes :/ EDIT I manage to fix Macports issue, but not py2app one. If I get it right, py2app try to create a 32-bits app, while Core Foundation files on Snow Leopard are for 64 bits architectures. Damn. Either I build this on Leopard, either I have to find a way to create a 64bit app with py2app, but then Snow Leopard only.

• Question - Setting dynamic HTML using Javascript to iFrames on Windows Mobile 6.1 - IE Mobile6

  - by swaroop

  Hi Experts, (excuse me if this is not the right forum to post - i couldn't find anything related to non-native programming and related to this topic) I Am trying to set a dynamic HTML into an iFrame on the webpage. I have tried a couple of things but none of them seem to work. I m able to read the innerHTML but can't seem to update it. // Able to read using document.getElementById('iFrameIdentifier').innerHTML; // On Desktop IE, this code works document.getElementById('iFrameId').contentWindow.document.open(); document.getElementById('iFrameId').contentWindow.document.write(dynamicHTML); document.getElementById('iFrameId').contentWindow.document.close(); Ideally the same function should work as how it works for div's but it says 'Object doesn't support this method or property". I have also tried document.getElementById('iFrameId').document.body.innerHTML. This apparently replaces the whole HTML of the page and not just the innerHTML. I have tried out a couple of things and they didn't work document.getElementById('iFrameId').body.innerHTML document.frames[0].document.body.innerHTML My purpose is to have a container element which can contain dynamic HTML that's set to it. I've been using it well till now when I observed that the setting innerHTML on a div is taking increasing amount of time because of the onClicks or other JS methods that are attached to the anchors and images in the dynamic HTML. Appears the JS methods or the HTML is some how not getting cleaned up properly (memory leak?) Also being discussed - http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_26185526.html#a32779090

• Displaying shifts on a timetable/calendar using C#

  - by Dave Peters

  I am very much a beginner and have experience of SQL and a tiny amount of VBA. What I am looking to do is create a tool to pull shift times from a database and to display them on a timetable/calendar. It will be part of a desktop application that the (very tech illiterate) end users will use to view and amend shift patterns. In essence it will be a grid with days on one axis and people on the other (I would however like to have the blocks proportional to shift length). In my mind it would potentially be a simple Gantt chart. All computing stuff I’ve learnt has been through trial and error and I want to use this project to get a much better understanding of C# as well as to get to the end product. I have been reading around for ways to tackle the problem and my issue is creating the timetable framework to which I will bind the data. I am using Visual Studio 2010 and SQL Server 2008 R2. Do you know of good resources which will either start me on the road to designing my own interface or give a basic framework I can adapt? All the resources I’ve found so far have been in different languages or for web based applications. Thank you for your time.

• Performance problem with System.Net.Mail

  - by Saif Khan

  I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

• Change made in the Converter will notify the change in the bound property?

  - by Kishore Kumar

  I have two property FirstName and LastName and bound to a textblock using Multibinidng and converter to display the FullName as FirstName + Last Name. FirstName="Kishore" LastName="Kumar" In the Converter I changed the LastName as "Changed Text" values[1] = "Changed Text"; After executing the Converter my TextBlock will show "Kishore Changed Text" but Dependency property LastName is still have the last value "Kumar". Why I am not getting the "Changed Text" value in the LastName property after the execution?. Will the change made at converter will notify the bound property? <Window.Resources> <local:NameConverter x:Key="NameConverter"></local:NameConverter> </Window.Resources> <Grid> <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource NameConverter}"> <Binding Path="FirstName"></Binding> <Binding Path="LastName"></Binding> </MultiBinding> </TextBlock.Text> </TextBlock> </Grid> Converter: public class NameConverter:IMultiValueConverter { #region IMultiValueConverter Members public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { values[1] = "Changed Text"; return values[0].ToString() + " " + values[1].ToString(); } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion }

• Looking for Hardware that will easily interface with my .NET code.

  - by SkippyFire

  I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

• Job Opportunities

  - by James

  I have a few questions about my job opportunities and I appreaciate it if people could give me some feedback on what I should have in front of me. I am graduatating from a University of Wisconsin--La Crosse this December with a degree in CS and a math minor. I have a cumulative GPA of 3.84 and a major GPA of 4.0 right now (though I still have many classes in front of me). I already have a degree from the U of Minnesota (History, 3.69 GPA) and have worked in the business world for 3+ years (working for a small company in the baseball world, doing some computer programming, statistical research, operations work, technical writing, etc.) I know Java and C well, also am comfortable with Perl. I should have a good grasp of SQL by graduation. I am looking to get a nice programming job (and will be open to moving). Anyone have any advice on things I should learn etc? Also, I would like to know what everyone thinks about my chances of landing a decent job (I realize that is subjective). Also, any ideas on salary I should be looking for (say I am working a metropolitan area). Thanks.

• Android Apps not working in emulator

  - by Mohit Deshpande

  None of my apps work in the emulator. I am running Ubuntu 9.10 and everytime I try to access my UI, the app crashes. All I get is an "Sorry! The application ... has stopped unexpectedly". For EVERY app this happens. package com.mohit.helloandroid; import android.app.TabActivity; import android.content.Intent; import android.content.res.Resources; import android.os.Bundle; import android.widget.TabHost; public class HelloAndroid extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); //Resource object to get drawables TabHost tabHost = getTabHost(); //The activity tabhost TabHost.TabSpec spec; //Reusable tab spec Intent intent; intent = new Intent().setClass(this, HelloAndroid.class); spec = tabHost.newTabSpec("artists").setIndicator("Artists", res .getDrawable(R.drawable.tab_artists)) .setContent(intent); tabHost.addTab(spec); } } I don't know how this code could possibly throw a message like that.

• WPF - How to properly reference a class from XAML

  - by Andy T

  OK, this is a super super noob question, one that I'm almost embarrassed to ask... I want to reference a class in my XAML file. It's a DataTemplateSelector for selecting the right edit template for a DataGrid column. Anyway, I've written the class into my code behind, added the local namespace to the top of top of the XAML, but when I try to reference the class from the XAML, it tells me the class does not exist in the local namespace. I must be missing something really really simple but I just can't understand it... Here's my code. XAML: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:local="clr-namespace:CustomFields" xmlns:col="clr-namespace:System.Collections;assembly=mscorlib" xmlns:sys="clr-namespace:System;assembly=mscorlib" x:Class="CustomFields.MainWindow" x:Name="Window" Title="Define Custom Fields" Width="425" Height="400" MinWidth="425" MinHeight="400"> <Window.Resources> <ResourceDictionary> <local:RangeValuesEditTemplateSelector> blah blah blah... </local:RangeValuesEditTemplateSelector> </ResourceDictionary> </Window.Resources> C#: namespace CustomFields { /// /// Interaction logic for MainWindow.xaml /// public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); // Insert code required on object creation below this point. } } public class RangeValuesEditTemplateSelector : DataTemplateSelector { public RangeValuesEditTemplateSelector(){ MessageBox.Show("hello"); } } } Any ideas what I'm doing wrong? I thought this should be simple as 1-2-3... Thanks! AT

• Codility-like sites for code golfs

  - by Adam Matan

  Hi, I've run into codility.com new cool service after listening to one of the recent stackoverflow.com podcasts. In short, it presents the user with a programming riddle to solve, within a given time frame. The user writes code in an online editor, and has the ability to run the program and view the standard output. After final submission, the user sees its final score and which tests failed him. Quoting Joel Spolsky: You are given a programming problem, you can do it in Java, C++, C#, C, Pascal, Python and PHP, which is pretty cool, and you have 30 minutes. And it gives you an editor in a webpage. And you've got to just start typing your code. And it's going to time you, basically you have to do it in a certain amount of time. And it actually runs your code and determines the performance characteristics of your code. It is intended for job interview screenings, but the idea seems very cool for code-golfs and for practicing new languages. Do you know if there's any proper open replacement? Adam

• Differences between iPhone/iPod Simulator and Devices

  - by Allisone

  Hi, since I started iPhone/iPod Development I have come across some differences between how the simulator and how real device react. Maybe I will come across some other differences I will have to figure out as well, maybe other people haven't met these problems here (YET) and can profit from the knowledge, and maybe you know some problems/differences that you would have been happy to know about earlier before you spent several hours or days figuring out what the heck is going on. So here is what I came across. Simulator is not case sensitive, Devices are case sensitive. This means a default.png or Icon.png will work in simulator, but not on a device where they must be named Default.png and icon.png (if it's still not working read this answer) Simulator has different codecs to play audio and video If you use f.e. MPMoviePlayerController you might play certain video on the simulator while on the device it won't work (use Handbrake-presets-iPhone & iPod Touch to create playable videos for Simulator and Device). If you play audio with AudioServicesPlaySystemSound(&soundID) you might here the sound on simulator but not an a device. (use Audacity to open your soundfile, export as wav and run afconvert -f caff -d LEI16@44100 -c 1 audacity.wav output.caf in terminal) Also there is this flickering on second run problem which can be resolved with an playerViewCtrl.initialPlaybackTime = -1.0; either on the end of playing or before each beginning. Simulator is mostly much faster cause it doesn't simulate the hardware but uses Mac resources, therefore f.e. sio2 Apps (OpenGL,OpenAL,etc. framework) run much better on simulator, well everything that uses more resources will run visibly better in simulator than on device. I hope we can add some more to this.

• How can I write classes that don't rely on "global" variables?

  - by Joel

  When I took my first programming course in university, we were taught that global variables were evil & should be avoided at all cost (since you can quickly develop confusing and unmaintainable code). The following year, we were taught object oriented programming, and how to create modular code using classes. I find that whenever I work with OOP, I use my classes' private variables as global variables, i.e., they can be (and are) read and modified by any function within the class. This isn't really sitting right with me, as it seems to introduce the same problems global variables had in languages like C. So I guess my question is, how do I stop writing classes with "global" variables? Would it make more sense to pretend I'm writing in a functional language? By this I mean having all functions take parameters & return values instead of directly modifying class variables. If I need to set any fields, I can just take the output of the function and assign it instead of having the function do it directly. This seems like it might make more maintainable code, at least for larger classes. What's common practice? Thanks!

• Open Source CMS (.Net vs Java)

  - by CmsAndDotNetKindaGuy

  I must say up-front that this is not a strictly programming-related question and a very opinionated one. I am the lead developer of the dominant .Net CMS in my country and I don't like my own product :). Managerial decisions over what is important or not and large chunks of legacy code done before I joined gives me headache every day I go for work. Anyway, having a vast amount of experience in web industry and a very good grasp of C# and programming practices I'm designing my own CMS the past few months. Now the problem is that I'm an open source kinda guy so I have a dilemma. Should I use C# and .Net which has crippled multi-platform support or should I drop .Net entirely and start learning Java where I can create a truly open-source and cross-platform CMS? Please don't answer that I should contribute to an existing open source CMS. I ruled that out after spending a great deal of time searching for something similar in structure to what I have in mind. I am not a native speaker, so feel free to correct my syntax or rephrase my question.

• Replacing/Extending Visual Studio's Generate Stub in Visual Studio 2010

  - by devoured elysium

  When we write the name of a method that doesn't exist, Visual Studio 2010 asks us if we'd like to generate a method stub with that name. What I'd like to know if is it possible to replace that same code stub generating command with one made by myself. I never did any kind of extensibility programming for Visual Studio so I have a couple of questions: How hard is it? Is it something I can learn in a couple of nights, or is it something that'll make me "lose" a lot of time? It seems to me that there isn't a lot of support for that kind of programming, as generally people are not that interested in developing solutions that extend the Visual Studio IDE. I searched on SO and it doesn't appear to have many threads about extending Visual Studio. I don't know how the generate method stub thing works in Visual Studio, but I just wanted to turn it into something a bit more flexible and useful. Has anyone dealt with these kind of things before, that can give me a pointer to where to start? I know of MS VSX site but that has a lot of resources and can be overwhelming for someone new to the subject as I am. What technology will I need to use? T4? Maybe I'll need to know a lot about the code, like Visual Studio does, so I can know other method's type arguments, names, etc. Is that what T4 is for? Thanks

• Use a resource dictionary as theme in Silverlight

  - by SaphuA

  Hello, I have developed an application which allows the user to switch between themes. I'm doing this by including the xaml file as a resource in my project and using the following code: MainTheme.ThemeUri = new Uri("SilverlightApplication1;component/Themes/[ThemeName]/Theme.xaml", UriKind.Relative); This worked well, untill I found these themes: http://timheuer.com/blog/archive/2010/05/17/silverlight-4-tools-released-and-new-application-templates.aspx The difference is that these themes consist of multiple files. So I made a Theme.xaml file that only includes MergedDictionaries so I could still use the code above. This is the Theme.xaml file for the Cosmopolitan theme. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="CoreStyles.xaml"/> <ResourceDictionary Source="SDKStyles.xaml"/> <ResourceDictionary Source="Styles.xaml"/> <ResourceDictionary Source="ToolkitStyles.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> However, when I run the c# code above I get the following exception: System.Windows.Markup.XamlParseException: Failed to assign to property 'System.Windows.ResourceDictionary.Source'. Just to be clear, using the MergedDictionaries method does work when I set it in my App.xaml: <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Themes/Cosmopolitan/Theme.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> What am I doing wrong? Thanks!

• Force ListViewItem Background colour to change when bound item it is bound to changes.

  My ItemContainerStyle works perfectly when a ListViewItem is added: <Style x:Key="ItemContStyle" TargetType="{x:Type ListViewItem}"> <Style.Resources> <SolidColorBrush x:Key="lossBrush" Color="Red" /> <SolidColorBrush x:Key="newPartNo" Color="LightGreen" /> <SolidColorBrush x:Key="noSupplier" Color="Yellow" /> <Orders:OrderItemStatusConverter x:Key="OrderItemConverter" /> </Style.Resources> <Style.Triggers> <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=DataContext, Converter={StaticResource OrderItemConverter}}" Value="-1"> <Setter Property="Background" Value="{StaticResource lossBrush}" /> </DataTrigger> <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self},Path=DataContext, Converter={StaticResource OrderItemConverter}}" Value="-2"> <Setter Property="Background" Value="{StaticResource newPartNo}" /> </DataTrigger> <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self},Path=DataContext, Converter={StaticResource OrderItemConverter}}" Value="-3"> <Setter Property="Background" Value="{StaticResource noSupplier}" /> </DataTrigger> </Style.Triggers> </Style> However when the source item changes, the trigger is not fired and the background colour is not what I expect. How can I make the trigger fire?

• Organizing code, logical layout of segmented files

  - by David H

  I have known enough about programming to get me in trouble for about 10 years now. I have no formal education, though I've read many books on the subject for various languages. The language I am primarily focused on now would be php, atleast for the scale of things I am doing now. I have used some OOP classes for a while, but never took the dive into understanding principals behind the scenes. I am still not at the level I would like to be expression-wise...however my recent reading into a book titled The OOP Thought Process has me wanting to advance my programming skills. With motivation from the new concepts, I have started with a new project that I've coded some re-usable classes that deal with user auth, user profiles, database interfacing, and some other stuff I use regularly on most projects. Now having split my typical garbled spaghetti bowl mess of code into somewhat organized files, I've come into some problems when it comes to making sure files are all included when they need to be, and how to logically divide the scripts up into classes, aswell as how segmented I should be making each class. I guess I have rambled on enough about much of nothing, but what I am really asking for is advise from people, or suggested reading that focuses not on specific functions and formats of code, but the logical layout of projects that are larger than just a hobby project. I want to learn how to do things proper, and while I am still learning in some areas, this is something that I have no clue about other than just being creative, and trial/error. Mostly error. Thanks for any replies. This place is great.

I am new to iphone sdk (latest) as you can imagine, so I have been going through the developer documentation, various forums and stackoverflow to learn. Apple's avTouch sample application was a great start. But I want my app to play all the 10 tracks one by one. All the songs are added to resources folder and are named as track1, track2...track10. In the avTouch app code I can see the following 2 parts which is where I think I need to make changes to achieve what I am looking for. But I am lost. // Load the array with the sample file NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"m4a"]]; - (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag { if (flag == NO) NSLog(@"Playback finished unsuccessfully"); [player setCurrentTime:0.]; [self updateViewForPlayerState]; } can anyone please help me on 1. how to load the array with all the 10 tracks which are added to resources folder 2. and when I hit play, player should start the first track. when the 1st track ends 2nd track should start and so on for the remaining tracks. Thank You

• What is Adobe Flex? Is it just Flash II?

  - by Adam Davis

  Question Alright, I'm confused by all the buzzwords and press release bingo going on. What is the relationship between flash and flex: Replace flash (not really compatible) Enhance flash The next version of flash but still basically compatible Separate technology altogether ??? If I'm starting out in Flash now, should I just skip to Flex? Follow up Ok, so what I'm hearing is that there's three different parts to the puzzle: Flash The graphical editor used to make "Flash Movies", ie it's an IDE that focuses on the visual aspect of "Flash" (Officially Flash CS3?) The official name for the display plugins (ie, "Download Flash Now!") A general reference to the entire technology stack In terms of the editor, it's a linear timeline based editor, best used for animations with complex interactivity. Actionscript The "Flash" programming language Flex An Adobe Flash IDE that focuses on the coding/programming aspect of "Flash" (Flex Builder?) A Flash library that enhances Flash and makes it easier to program for (Flex SDK?) Is not bound to a timeline (as the Flash IDE is) and so "standard" applications are more easily accomplished. Is this correct?

• How to Manage project in this scenario

  - by vijay.shad

  Hi All, I am working on a web application which has got good amount of static or pre-login pages. These pages can have some simple forms as well where we would like to capture the visitor's details. Post login, I have got my main application. I am confused about the development and deployment architecture of my application. Post login part of my application has a release cycle of 1-2 months while pre-login pages are to be updated on a weekly basis. It is difficult to make a release of pre-login pages as the overall war also contains post-login application & which sometimes is not release ready. Currently, I have got both these parts bundled in the single war project. Please help me by letting me know the best practices whereby I can achieve following: Manage the releases of these two parts independently. I am using Maven. So is there a way I can share the resources, such as CSS, images etc between these two parts. Header and footer of my application is going to be same on pre-login & post-login pages. I was thinking of deploying these apps as two war files in my tomcat container. But then how will I manage the common resources like Css, images etc. Rgds Vijay
