• Can't remove Default.png?

  - by Matt Winters

  Weird one... I had been fooling around with an initial splash screen but decided not to use it. But now, although I deleted Default.png from Resources, the splash screen still appears in the Simulator when I start the app. Default.png isn't in the project folder, I close and reopen Xcode, splash screen still there. Close ands reopen Simulator, splash screen still there. I remove the app from the Simulator, build, and the splash screen is still there Default.png. Any ideas?

• Mandatory Parameters in Request object (WCF)

  - by Martin Moser

  lHi, I'm currently writing a WCF service. One of those methods get's a request object and returns a response object. In the request there are a couple of value-type members. Is there a way to define members are mandatory in the declarative way? I'm in an early stage of development and I don't want to start with versioning now. In addition I don't want to have method sig with 25 parameters, therefore I created the request object. The problem I have is that due to the value-types, I can never be sure if the consumer of the service intended to have the default value in there, or it was just by lazyness. On consumer side you don't easily detect that you probably missed that property. So I would like to have something that forces the caller of the service to provide an value, and if not he ideally get's a compile-time error. any ideas? tia, Martin

• How can a client try to reconnect to a server after a first failed try with WCF?

  - by djerry

  Hey guys, I'm using a client - server app. When a client starts, he gets a login-screen. When the server is not up yet, the call to the server will throw an exception which i catch (EndpointNotFoundException). I show a messagebox telling the user the server is offline. When he tries to reconnect again, it will throw another exception (CommunicationObjectFaultedException), even though the server is online. When a new client starts then, he can connect to the server. But the client who attempted before, still gets the error. My question now is how can the first client login after a failed first try without having to start his program again. So i want to clear the communicationchannel of its faulted state or something like that. Thanks in advance.

• Mysql - Grouping the result based on a mathematical operation and SUM() function

  - by SpikETidE

  Hi all... I'm having the following two tables... Table : room_type type_id type_name no_of_rooms max_guests rate 1 Type 1 15 2 1254 2 Type 2 10 1 3025 Table : reservation reservation_id start_date end_date room_type booked_rooms 1 2010-04-12 2010-04-15 1 8 2 2010-04-12 2010-04-15 1 2 Now... I have this query SELECT type_id, type_name FROM room_type WHERE id NOT IN (SELECT room_type FROM reservation WHERE start_date >= '$start_date' AND end_date <= '$end_date') What the query does is it selects the rooms that are not booked between the start date and end date. Also, as you can see from the reservation table, we also have 'number of rooms booked between the two dates' factor also... I need to add this 'no.of booked rooms between the two dates' factor also in to the query... The query should return the type of rooms for which at least one room is free between the two dates. I worked out the logic but just can't represent it as a query....! How will you do this...? Thanks for your suggestions..!

• OpenXml - How to identify whether the paragraph extends to next page

  - by K.V.

  From aspx page, I dynamically add paragraphs to a word document using OpenXml SDK. In this case, a page break within a paragraph is not allowed. So in case a paragraph starts in middle of page 1 and extends to page2 then it should actually start in Page2. However, if it ends in the same page it is okay. How to achieve this? Is there a way to set in th document that page break is not allowed within a paragraph? Any input is highly appreciated.

• HAML-like syntax for non-HTML documents?

  - by Peter

  I love using HAML for HTML documents. It has clean syntax that's much more attractive than ERB. It works perfectly for HTML documents. What about for non-HTML? Such as, for example, an email or text document with certain automatically-substituted components? I've been falling back to ERB, but don't like the heavy syntax compared to HAML. Is there any way to use HAML for ordinary documents without having divs and html elements appear when % and . start a line? Or is there some alternative to both HAML and ERB that I should investigate?

• "Compiling" content with short tags to var, without eval()

  - by Spot

  To start off, let me clear the air by saying we are aware of the dis/advantages to using short tag syntax in PHP. That is not what this question is about. Is there a way to "include" a file containing short tag code, into a variable, and have PHP actually parse the code? include/require obviously do not provide the data in a workable form, and output buffering does not parse the short tag code because it happens at runtime. Using eval() is simply not an option. Suggestions?

• how to implement windows service loop that waits for a period in C# / .NET2.0

  - by matti

  My question is that is this the best practice to do this. Couldn't find any good examples. I have following code in file created by VS2005: public partial class ObjectFolder : ServiceBase { protected override void OnStart(string[] args) { ObjectFolderApp.Initialize(); ObjectFolderApp.StartMonitorAndWork(); } protected override void OnStop() { // TODO: Add code here to perform any tear-down necessary to stop yourservice. } } then: class ObjectFolderApp { public static bool Initialize() { //all init stuff return true; } public static void StartMonitorAndWork() { Thread worker = new Thread(MonitorAndWork); worker.Start(); } private static void MonitorAndWork() { int loopTime = 60000; if (int.TryParse(_cfgValues.GetConfigValue("OfWaitLoop"), out loopTime)) loopTime = 1000 * loopTime; while (true) { /* create+open connection and fill DataSet */ DataSet ofDataSet = new DataSet("ObjectFolderSet"); using (_cnctn = _dbFactory.CreateConnection()) { _cnctn.Open(); //do all kinds of database stuff } Thread.Sleep(loopTime); } } }

• Does UIActivityIndicator require manual threading on iPhone

  - by Akusete

  I am running creating an iPhone application which performs a costly operation and I wanted to create an activityIndicator to let the user know the application has not frozen. The operation is performed entirely in one event call... so there is no chance for the UI framework to receive control to actually display and animate this indicator. The sample apps which use the UIActivityIndicator (or any other similar animation) start and stop the animation in different events, triggered separately at different stages of the program. Do I need to manually create a separate thread to run my operation in, or is there already default support for this kind of behavior?

• How do you get "in the zone"?

  - by Wayne Werner

  Hi, I've just started my first real programming job and am pleased to discover that this is exactly what I want to do for the rest of my life. When it comes round to ~1 hour before it's time to go home and I think "Man, do I have to go home already?" I'd say that's A Good Thing(tm). One thing I've discovered though is that it takes a little while for my brain to get "in gear" or "in the Zone", so I'm curious what other folks do to get programming at their prime. My current flow is when I get here I visit SO and look at the interesting problems - I find it helps get my brain moving. After 20-30 minutes I start looking at my code/specs/etc to decide what I want/need to work on first. So how do you get started?

• PHP script for creating calendar table or jquery complete solution required

  - by finn_meister

  Ok so this is what I want to make: http://i44.tinypic.com/eiwphl.jpg red = booked green = available I have data in mysql in the format of: property_id, booked_from, booked_until . Before I start trying to create the correct loops etc to create and style the table, i thought i best ask if there are already good jquery plugins / php classes create this visual interface and uncluttered enough to allow me to add a select date range method (like Google Analytics)? I'm looking for something to create a basic calendar table on a loop, which i can then style and add jquery features. Though worth asking if there's a complete package that already does what i plan on making?!! (jquery ui's date-picker doesn't look powerful enough / easy enough to modify)

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

  - by rgoytacaz

  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. This is the error that seam generate, got me. [hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering) [hibernate] 1. task: hbm2java (Generates a set of .java files) [hibernate] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). [hibernate] log4j:WARN Please initialize the log4j system properly. [javaformatter] Java formatting of 0 files completed. Skipped 0 file(s). Any ideas? The seam-gen was supposed to generate some entity classes, but its not. I suppose that error is causing the mis-behavior. Regards

• Jquery help for current time indication within a range

  - by Appster

  I'm looking for a simple light-weight jquery plugin that'll help me show something like this in my website: Essentially, this is like a timeline. I know the start and end dates (in that, they don't change) and the position of today's date just gives an indication of how far along I am into a task I took up on Jun 1, 2012. That's all I need it for - a better visual indication of my current status. I've found a lot of jquery timeline plugins but they are too complex for what I'm trying to do. Any ideas or suggestions? Thanks in advance.

• How to plan my web based project before starting code ?

  - by Arsheep

  Me and my friend started working together as partners , we have decided to make Kick-as* website after website. We have the ideas written down like 100's of them (yes we are choosing best and easy among them first). My friend does the layout design and arranging things , and my part is coding and server management. The little problem i am facing is lack of experience in planing a project. What i do is, I just start the code straight away and along with code I make DB, like when i need a table i make it. I know this is very bad approach for a medium sized project. Here at stackoverflow i saw lots of experienced coders. Need to learn a lot from you guys :) . So can you plese help me on how to plan a project and what coding standard/structure/frameworks to be used (I do PHP code). Thanks in advance.

• Learning Objective-C 2.0 and ASP.NET 4.0 simultaneously?

  - by Sahat

  (HOBBY) I own a Macbook Pro and iPod Touch so developing iPhone/iPod/iPad apps seems like a logical thing to do in order to get some experience in the programming field. Besides I want to write a new application similar to the Capsuleer (Character skills monitor app for EVE Online MMO) but with more features. It's something I'd love to have on my own iPod Touch and I am sure other people will welcome a new EVE Online app for their iPhone or iPod Touch. (CAREER) I want to learn ASP.NET (and possibly Silverlight later on) for my potential future job. I plan to work in the .NET field, so it's a good idea for me to start learning C# and ASP.NET ASAP. Is it a good idea to learn completely unrelated technologies at the same time? Or would it be better to learn one thing at a time? Objective-C first, and ASP.NET second. Or vice versa. Thanks, Sahat

• How to make WPF app work as a child process in Citrix

  - by RichardOD

  I am working on a 3rd party application that allows plugins to be written in .NET 1.1. I have decided I would like to write my plugin in a seperate process that is called from the .NET 1.1 application (achieved using Process.Start). This is fine- I create a new process that is a WPF app. When I launch this through MSTSC everything works as expected, however when I run the app through Citrix, the WPF child app fails to render correctly, and the mouse position starts going crazy- the child process window is basically not usable. Is there a way to avoid this happening? If I create a seperate WPF application and deploy this through Citrix everything works fine. If I create a child Windows forms app in .NET 3.5, that also works fine.

• designing classes and objects in .net for a restaurant assignment

  - by Dell Boy

  I have received an assignment at School for creating a Restaurant site. I have to use objects and classes (OOP) for my assignment. I have the foundations of the OOP in .net, but what I don't know is how can I design this assignment to be object-oriented. I don't know how to start it. The requirement is like this: The menu has to be saved in a database and retrieved from it. The menu is devided in appetizers, Salades, Main Meal, Pastas, Wines, Beverages, Extras, Do I create classes like this: Base Class: Menu Derived classes: Appetizers, Salades, Main meal, Pastas, wines, etc. If you have a good example about how to create classes from a Menu that will be great. You don't have to rely on the example I gave above. The menu can be anything. I can deside what the menu will contain. thanks a lot. I am waiting for some help. Please

• How can I detect collisions between two images in c#?

  - by Shane Callanan

  hope you can help me out with this one. I'm new to c# so am very inexperienced. But basically I'm trying to make a game in which certain objects fall from the sky. Some objects like feathers take a while to drop, while metal balls will drop faster. You start off with a certain amount of cash and can buy weapons of your choice to place on the ground below. Now I've never done anything to do with collisions before, so simple answers will be of much help! Here are some of the collisions that will be in the game: (Not sure if different types of collisions are coded differently) -Collision between bullets and falling objects -Collision between falling objects and the ground (which is inanimate) -Collisions between falling objects and a certain radius around another object (for example, if a weapon gives off a radiation beam starting from its centre) -Collisions between rotating objects (rotating blade) and falling objects If someone could help me with this, it would be much appreciated!

• How to programmatically launch a chromecast app from command line

  - by pushmatrix

  I want to launch a Chromecast app but NOT using the chrome extension or iOS or Android. Doing this from command line. I noticed that you can send a POST to your chromecast, and it will launch an app. For example if I do curl -H “Content-Type: application/json” http://CHROMECAST_IP:8008/apps/YouTube -X POST -d ‘v=oHg5SJYRHA0' Then it will start up youtube. But for some reason I can't do this with custom apps (in dev mode). I thought I'd be able to send a POST to http://CHROMECAST_IP:8008/apps/MY_REGISTERED_APP_ID, but no luck. I just get a 404 response. Hmmm... My app is just a simple webpage (it is not streamed media). I want to run a little headless server that starts my chromecast app everyday via a CRON task. Any help is greatly appreciated! Thanks :)

• How to implement a Google-chrome-like title bar for Java SWT application

  - by MartyC

  I have inherited development of a Java/SWT application running on Windows only. One of the feature requests that I need to scope is a Google-chrome-type title bar in place of the SWT windows title bar. The application's tabs appear at the same level as the window control buttons. My understanding is that I will need to: write a Windows widget capable of rendering the custom look and managing tabs as opposed to menus. expose the Windows widget as a dll for use in Java via JNI write a custom SWT widget to wrap it and expose the tab management interface. I have a lot of experience with Java programming, GUI programming with Swing/AWT, and non-GUI C# programming. Windows GUI programming and SWT are new to me so I'm not sure where to start. The best I have found so far is a 2001 article on writing your own SWT widget. My biggest unknown is the best way to implement a custom Windows application-window.

• ASP.NET forgets dlls in bin directory

  - by Timothy Strimple

  We have a plugin system on a WCF service that checks libraries placed in the bin folder for certain assembly level attributes and loads them. This allows customization of certain service calls based on which client is making the call. This works great most of the time. However, sometimes it seems to lose the dll, which causes the service to revert back to the default implementation for every client. The solution so far has been to just move the dll file out of the bin folder, and back in. This causes asp.net to pick up the file and customizations start working again. I'm at a loss for why the assembly is getting missed like that after a certain amount of time. Any ideas as to what might be causing this?

• Reset auto increment column value in script mysql

  - by Lucia

  Hi, I have two mysql tables, one needs to start its auto-increment column id with the last value of the last inserted row in the other table (plus 1). According to mysql manual you can restart the value of an auto increment column like this: mysql ALTER TABLE tbl AUTO_INCREMENT = 100; However, this is not possible: mysql ALTER TABLE tb2 AUTO_INCREMENT = (SELECT MAX(id) FROM tbl1); I need to perform something like this because I'm filling the tables using a script. Is there another way to achieve it?
