  • How to load the App.config file?

    - by Amokrane
    Hi, I'm parsing the App.config file of a project. This config file has been loaded from a caller project. Inside the called project, I have something like: XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("app.config"); // Some parsing... Unfortunately the app.config file is not correctly located. Apparently the Load method is browsing the ~/bin/Release directory of the caller project, but the app.config file is located in the ~ directory. Is there any way I can load this App.config file correctly? Thanks

  • Port a live system from App Engine Helper to App Engine Patch

    - by Alexander
    I am running a live system that is currently serving about 20K pages a day which is based on App Engine Helper (Python) with session support provided by AppEngine utilities. One problem that I have been having is that sessions are occasionally randomly logging out. I would like to try using the App Engine Patch, since it has "native" django session support, but I am worried that this is possibly going to be like doing a brain transplant. Specifically, current database models are all inhereted from BaseModel provided by the App Engine Helper. While, App Engine Patch does not have this inheritance. Does anyone know if it is possible to migrate a live system from App Engine Helper to App Engine Patch? If so, do you have any advice or warnings that I should heed, before attempting this transition? Thank you and kind regards Alex

  • Purchase music from iTunes store without leaving app?

    - by chris.o.
    Hi all, Is anyone aware of a standard way of allowing a user to purchase music from the app store without leaving the app? For instance, if a band has an album for sale on iTunes and then releases an iPhone game featuring the band members, is there a "standard way" to allow the user to buy songs without leaving the app? From what I can tell, there is not and, given that in the example above, the album is not content specifically for the app, it would not qualify for In-App purchase. Any suggestions? Thanks, Chris

  • Is support for recovering purchases mandatory for consumable products?

    - by Drux
    Apple's documentation for iOS 7 makes me think it is not, for it makes a distinction between "restored by the system" (i.e. built into iOS 7), "restored by your app" (i.e. functionality required inside app"), and "not required". The fact there being three (and not two) options and product type "consumable" being marked as "not restored" makes me think that an app that does not support restoring consumable product may still pass Apple's review process. However this popular question and answer seem to suggest that such support is required ("I read somewhere ...") But would this not amount to "consumable" taking on "restored by your app" semantics, which seems to contradict the quoted piece of Apple documentation.

  • py2app generates .app with no errors but .app crashes and quits unexpectedly

    - by user3705730
    I am trying to use py2app and it generates .app with no errors but .app crashes and quits unexpectedly. I am trying to do this in virtualenv so I am not sure if that is an issue with all the paths. It works on my computer when all the virtual environments exist but as soon as I close them down, the .app no longer works.

  • Transferring ownership of an iPhone app on the app store

    - by kfitzpatrick
    My team and I have an app which we're going to be submitting to the store pretty soon, but we know that we'll be selling the app to another company in the near future. Does anyone have any experience with moving an app's ownership to another account? Specifically, when I sell an app to another company... ... how do we move the app to their account (what's the mechanism)? ... can my users still get updates (released by the new owner) without having to re-buy/re-download the app?

  • How to flush coverage data when my test cause app crash - For ios app

    - by Ypy
    I want to get the code coverage of my tests. So I set the settings, build an app with .gcno files and run it on simulator. It can get the coverage data successfully if there is no crash issue. But if the app crashed, I will get nothing. So how can I get the code coverage data when the app crash? In my thought, this is because it will not call __gcov_flush() method when app crash. I only add app does not run in background to my plist file, so __gcov_flush() is called only at the time I press Home button. Is there any way to call __gcov_flush() before the app crash?

  • best way to make this app/website combo?

    - by mharris7190
    I have an idea for an app that lets different bars upload drink specials via a webpage to that app. They would log in the website, and the website would prompt them with a box to input the drink specials. When they are done, the app pulls the information and creates a card for that bar. The app would launch into a week view where you select the day you want to see specials for. After the day is selected, it brings you to a scroll view with different bars' cards laid out vertically, each taking up the width of the screen, allowing the user to scroll through the deals for that day of the week. How should I go about doing this if I have very little programming experience? Is there any convention in doing an app like this? Can anyone suggest any reading material that would help? Thank you!

  • "pay if you want to" using in app purchases (iphone)

    - by Jonathan
    I realise that you can't use in app purchases for real things. But does an in app purchase actually have to give extra functionality in the app. Can it be used to have optional paying? I've made an app that really should be free but I'd like to make a little money even if it's only one 59p. So could I have an in app purchase which users can click to pay if they want to. it might sound stupid but I'm betting there is at least one person who would becase they are nice :)

  • Charms and the App Bar

    - by Dennis Vroegop
    Ok. I admit. I made a mistake in the last post about our planespotter app. I have dedicated a full part of the hub to Social. I also had a section called Friends but that made sense since I said that “Friends” is a special group of people that connect to each other through our app and only our app. Social however is sharing our spots with Twitter, Facebook and so on. Now, we could write that functionality in our app in a different section but there is one small problem with that: users don’t expect that. Ok, I admit. The mistake was quite deliberate to give me an excuse to write this part. But still: the mistake is one I see a lot. People are trying to do stuff in their application that they shouldn’t be doing. This always strike me as slightly odd: why do some work when others have already done it for you and you can just use it? After all: good developers are lazy (lazy people will always try to find the easiest way to do something and in development land this usually means the cleanest and best to support way…) So. What is that part that Microsoft has done for us and we don’t have to do ourselves? The answer lies on the right hand of your Win8 screen: This is a screenshot of my tablet (as you can see I am writing this right now….) When I swipe my finger from out of the screen on the right inside the screen (or move the mouse to the upper right corner) this menu will appear. Next to settings and the start menu button we’ll find the Search and the Share charms. These are two ways that your app can share the information it contains with the rest of the world, or at least: the rest of your system. So don’t write a Search feature in your app. Don’t write a Share feature in your app. It’s here already. Users, once they are used to Windows 8, will use that feature and expect it to work. If it doesn’t, they won’t like your app and you can kiss you dreams of everlasting fame goodbye. So use these two. What are they? Well, simply they are parts of a contract. In your app you say somewhere in code that you are supporting Search and Share. So when the user selects Share the system will interrogate the current app in the foreground if it supports this feature. Your app will say “But why, yes, I do!” Then the system will ask the app “Ok then, wisecrack, then share!” and you will have to provide the system with some information about the format. Other applications have subscribed to be at the receiving end of the Share contract. They have told the system that they support Sharing (receiving) and which formats they understand. If one or more of them support the formats you specify, the user will see them. The user clicks / taps on the app of their choice and data is moved from your app to the new one. So if you say you support Facebook and Twitter users can post data from your app to these networks by selecting Share. The same applies to Search. Don’t make a “search” button in your app but use the contract to tell the system that you support search and use that instead. Users will be grateful (remember that bar with men/women/creatures that are waiting for you?) The more and more people get to know Windows 8, the more they will use this. And if you are one of the people who wrote an app that helped them learn the system, well, that’s even better. So. We don’t have a Share or a Search button. We do have other buttons. Most important: we probably need a “New Spot” button. And a “Filter” might be useful. Or someway to open the camera so you can add a picture to the spot. Where will be put those? The answer is the “Appbar” . This is a application / context aware menu that slides up from the bottom of the screen when you move your finger / mouse from below the screen into it. From above downwards works just as well. Here you see an example of the appbar from the People app. (click on it for a larger version). This appears whenever you slide your finger up from below of down from above. This is where you put your commands. Remember, this is context aware so this menu will change when you are in different parts of your app or when you have selected different items. There are a few conventions when you create this appbar. First, the items on the right are “General” items, meaning they have little to do with what is on the screen right now. I think this would be a great place to add our “New Spot” icon. On the far left are items associated with the current selected item or screen. So if you have a spot selected, the button for Add Photo should be visible here and on the left hand side. Not everything is as clear as this, but this is what you should strive for. Group items together. And please note: this is the only place in Metro design where we are allowed to use lines as separators. So when you want to separate a group of icons from another group, add a line. Also note the simplicity of the buttons. No colors, no lights or shadows, no 3D. After a couple of years of fancy almost realistic looking icons people have finally decided that hey, this is a virtual world: it’s ok to look virtual as well. So make things as readable and clear as possible and don’t try to duplicate nature. It’s all about the information, remember? (If you don’t remember I’d like to point you to a older blog post of mine about the what and why of Metro). So.. think about the buttons a bit and think about Share and Search. What will you put there? Remember: this is the way the users interact with your apps and while you shouldn’t judge a book by its covers when it comes to people, this isn’t entirely so when it comes to apps. People DO judge an app by its looks and the way it feels. Take advantage of that. History has learned that a crappy app with a GREAT user interface gets better reviews than a GREAT app with a lousy UI… I know: developers will find this extremely unfair but that’s the world we live in (No, I am not saying you should deliver rubbish apps). Next time: we’ll start by building the darn thing!

  • Mac Terminal.app: Force '^C' to be printed when editing current prompt, then aborting it

    - by Stefan Lasiewski
    This is the opposite of Prevent “^C” from being printed when aborting editing current prompt. I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character. I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX. This only happens within Apple's Terminal.App. If I SSH to a remote Linux or FreeBSD box, then ^C is printed. So, this is clearly just a local setting. Update: Here is the output of stty -a, as requested by @quack quixote : $ stty -a speed 9600 baud; 41 rows; 88 columns; lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo -extproc iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel iutf8 -ignbrk brkint -inpck -ignpar -parmrk oflags: opost onlcr -oxtabs -onocr -onlret cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>; eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W; After typing stty sane, stty -a will output the following.

  • Consume webservice from a .NET DLL - app.config problem

    - by Asaf R
    Hi, I'm building a DLL, let's call it mydll.dll, and in it I sometimes need to call methods from webservice, myservice. mydll.dll is built using C# and .NET 3.5. To consume myservice from mydll I've Added A Service in Visual Studio 2008, which is more or less the same as using svcutil.exe. Doing so creates a class I can create, and adds endpoint and bindings configurations to mydll app.config. The problem here is that mydll app.config is never loaded. Instead, what's loaded is the app.config or web.config of the program I use mydll in. I expect mydll to evolve, which is why I've decoupled it's funcionality from the rest of my system to begin with. During that evolution it will likely add more webservice to which it'll call, ruling out manual copy-paste ways to overcome this problem. I've looked at several possible approaches to attacking this issue: Manually copy endpoints and bindings from mydell app.config to target EXE or web .config file. Couples the modules, not flexible Include endpoints and bindings from mydll app.config in target .config, using configSource (see here). Also add coupling between modules Programmatically load mydll app.config, read endpoints and bindings, and instantiate Binding and EndpointAddress. Use a different tool to create local frontend for myservice I'm not sure which way to go. Option 3 sounds promising, but as it turns out it's a lot of work and will probably introduce several bugs, so it doubtfully pays off. I'm also not familiar with any tool other than the canonical svcutil.exe. Please either give pros and cons for the above alternative, provide tips for implementing any of them, or suggest other approaches. Thanks, Asaf

  • Google App Engine Needs Index Error

    - by Andrew Johnson
    I am currently getting a needs index error on my app engine app: http://www.gaiagps.com/wiki/home. I believe this index should have been created automatically by my index.yaml file (see below). Googling a bit, I think I just need to wait for my index to be built. Is this correct, or do I need to do something manually? Is there some sort of index-building queue? My tables are very, very small right now. EDIT: I added the line "indexes:" to my app.yaml, and now app engine reports the index is building, so I think this is fixed. It's weird that this file was wrong considering I've never touched it. indexes: # AUTOGENERATED # This index.yaml is automatically updated whenever the dev_appserver # detects that a new type of query is run. If you want to manage the # index.yaml file manually, remove the above marker line (the line # saying "# AUTOGENERATED"). If you want to manage some indexes # manually, move them above the marker line. The index.yaml file is # automatically uploaded to the admin console when you next deploy # your application using appcfg.py. - kind: Revision properties: - name: name - name: created The app works on my dev server, but not in production. However, on my dev console, I have noticed this error (EDIT: THIS ERROR IS GONE NOW THAT I ADDED indexes: to the app.yaml file above): ERROR 2009-10-18 04:46:51,908 dev_appserver_index.py:176] Error parsing /gaiagps.com/index.yaml: 'NoneType' object is not callable in "<string>", line 13, column 3: - kind: Revision ^

  • Setting Gmail as mail server

    - by Tim S.
    I’m in a slightly weird situation right now, and I don’t have sufficient knowledge to sort this myself without truly understand what I’m doing. Yesterday, I’ve registered a domain (.com) and ordered a VPS, attached to that domain. Chances are I may receive mail on my .com address to confirm the domain. Unfortunately, that domain is nothing, but an empty domain. Currently, there’s no mailserver that fetches my mail. Because I don’t have a mailserver available, I (temporarily) want to use Gmail. I prefer to add it to my existing, personal address, but I’m okay with creating a new account as well. I just want to read possible incoming mails. I’ve tried to set MX records to What do I need to do to get mail to a Gmail address? PS. I’m aware of Google, NSA, etc. PPS. I just want to receive mail. I don’t care if I can’t send via my domain. PPS. Detailed steps would be greatly appreciated, I’m a noob.

  • Facebook App EULA & Restrictions: What can't they do that my web app can?

    - by Adam Tannon
    I have written a nifty little web app (in Java/GWT/JS) and have been experimenting with the idea of making it available through Facebook as a Facebook App as well. After spending some time reading Facebook's developer docs, it seems like I can just create a Facebook App to point at any URL I want and use that as the app/canvas. It accomplishes this via iframes. So, my tentative plan is to just point it towards my (existing) web app so that I don't have to totally re-write it. But then that got me thinking: Facebook must regulate what sorts of things can be done through a Facebook App, vs. what an app can't do. For instance, I can't imagine I can point a Facebook App to point at a URL for a web app that accepts e-commerce payments (that would by-pass Facebook altogether and not allow them to take a cut from the ecom transaction!). Also, I can't imagine that Facebook allows developers to point their Facebook Apps to just any old URL without some sort of a scan, otherwise that would open Facebook up to the horrors of every security threat knownst to humanity. I know for a fact that when you write an iOS native app and put it up on the Apple App Store, that Apple actually scans your source code for violations of their EULA. So my question: does Facebook do the same? If so, what are their terms & conditions for what a Facebook app can/can't do? Suprisingly, I can't find this anywhere!! Thanks in advance!

  • Data Binding to Attached Properties

    - by Chris Gardner
    Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2013/06/14/data-binding-to-attached-properties.aspx When I was working on my C#/XAML game framework, I discovered I wanted to try to data bind my sprites to background objects. That way, I could update my objects and the draw functionality would take care of the work for me. After a little experimenting and web searching, it appeared this concept was an impossible dream. Of course, when has that ever stopped me? In my typical way, I started to massively dive down the rabbit hole. I created a sprite on a canvas, and I bound it to a background object. <Canvas Name="GameField" Background="Black"> <Image Name="PlayerStrite" Source="Assets/Ship.png" Width="50" Height="50" Canvas.Left="{Binding X}" Canvas.Top="{Binding Y}"/> </Canvas> Now, we wire the UI item to the background item. public MainPage() { this.InitializeComponent(); this.Loaded += StartGame; }   void StartGame( object sender, RoutedEventArgs e ) { BindingPlayer _Player = new BindingPlayer(); _Player.X = Window.Current.Bounds.Height - PlayerSprite.Height; _Player.X = ( Window.Current.Bounds.Width - PlayerSprite.Width ) / 2.0; } Of course, now we need to actually have our background object. public class BindingPlayer : INotifyPropertyChanged { private double m_X; public double X { get { return m_X; } set { m_X = value; NotifyPropertyChanged(); } }   private double m_Y; public double Y { get { return m_Y; } set { m_Y = value; NotifyPropertyChanged(); } }   public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged( [CallerMemberName] string p_PropertyName = null ) { if( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( p_PropertyName ) ); } } I fired this baby up, and my sprite was correctly positioned on the screen. Maybe the sky wasn't falling after all. Wouldn't it be great if that was the case? I created some code to allow me to move the sprite, but nothing happened. This seems odd. So, I start debugging the application and stepping through code. Everything appears to be working. Time to dig a little deeper. After much profanity was spewed, I stumbled upon a breakthrough. The code only looked like it was working. What was really happening is that there was an exception being thrown in the background thread that I never saw. Apparently, the key call was the one to PropertyChanged. If PropertyChanged is not called on the UI thread, the UI thread ignores the call. Actually, it throws an exception and the background thread silently crashes. Of course, you'll never see this unless you're looking REALLY carefully. This seemed to be a simple problem. I just need to marshal this to the UI thread. Unfortunately, this object has no knowledge of this mythical UI Thread in which we speak. So, I had to pull the UI Thread out of thin air. Let's change our PropertyChanged call to look this. public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged( [CallerMemberName] string p_PropertyName = null ) { if( PropertyChanged != null ) Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync( Windows.UI.Core.CoreDispatcherPriority.Normal, new Windows.UI.Core.DispatchedHandler( () => { PropertyChanged( this, new PropertyChangedEventArgs( p_PropertyName ) ); } ) ); } Now, we raised our notification on the UI thread. Everything is fine, people are happy, and the world moves on. You may have noticed that I didn't await my call to the dispatcher. This was intentional. If I am trying to update a slew of sprites, I don't want thread being hung while I wait my turn. Thus, I send the message and move on. It is worth nothing that this is NOT the most efficient way to do this for game programming. We'll get to that in another blog post. However, it is perfectly acceptable for a business app that is running a background task that would like to notify the UI thread of progress on a periodic basis. It is worth noting that this code was written for a Windows Store App. You can do the same thing with WP8 and WPF. The call to the marshaler changes, but it is the same idea.
