• Good or common naming conventions for xsd target namespaces

  - by Anne Schuessler

  I'm looking for some ideas for good naming conventions for xsd target namespaces. Basically I just need to make a definite decision on how to name the target namespace of my xsd so I try to get it right the first time. Changing it later would require changes to another system which is not in my control. Do you have any experience from past XML schema creations on what is a good and working solution? I've tried to find information online, but most examples just use very generic target namespaces like "http://exampleSchema" and similar. I'm actually trying to find some real life examples.

• Android SDK: Create image on touch

  - by dagonal

  Hello, I'm a bit stumped here, I'm trying to make it so an image (already in the drawable folder) gets created everytime you touch the screen and removed when the finger is lifted. I have the touch part coded already, overriding the onTouch method with a couple switch cases that handle each type of action (down, up, move, etc). But I can't for the life of me figure out how to make the image appear and then disappear with the coordinates (matrix?) of where the finger is. Any help would be greatly appreciated!

• JSF skips phases - How to debug that?

  - by Pentius

  Hey fellows, I have to debug a foreign jsf application thanks god. The problem is, that I submit a form, but the values aren't carried over. With a phase listener I can see, that the life cycle doesn't run completely through, so to say it skips phase 2 -5: After the restore view phase, the render response phase is directly called. I miss the apply values, validation, update model actions and so on. So, this could be a chicken-and-egg problem: 1. The responsible phases aren't called, so the new form input can't be carried over. 2. The system doesn't recognize any new input and therefore directly renders after restoring the view. I checked that there is no call of responseComplete() oder renderResponse(). I'm stuck somehow. Any idea to validate one of the two hypothesis? Or how to debug that in general? Did anybody have a similar problem?

• How can I most accurately calculate the execution time of an ASP.NET page while also displaying it o

  - by henningst

  I want to calculate the execution time of my ASP.NET pages and display it on the page. Currently I'm calculating the execution time using a System.Diagnostics.Stopwatch and then store the value in a log database. The stopwatch is started in OnInit and stopped in OnPreRenderComplete. This seems to be working quite fine, and it's giving a similar execution time as the one shown in the page trace. The problem now is that I'm not able to display the execution time on the page because the stopwatch is stopped too late in the life cycle. What is the best way to do this?

• Storing and retrieving CGPoints inside NSMutableArray

  - by Matt Dice

  I've looked through countless questions on here and elsewhere and cannot for the life of me figure out what I'm doing wrong. I'm trying to store an array of CGPoints as NSValues inside of an NSMutableArray named points like so on the iPhone: NSValue *point = [NSValue valueWithCGPoint:firstTouch]; NSLog(@"NSValue *point = %@", point); [points addObject:point]; NSLOG OUTPUT NSValue *point = NSPoint: {120, 221} Everything is going smooth converting from the CGPoint to NSValue. But when I try to retrieve the point I get nothing. NSValue *getPoint = [points objectAtIndex:0]; CGPoint thePoint = [getPoint CGPointValue]; NSLog(@"Point = %@", NSStringFromCGPoint(thePoint)); NSLOG OUTPUT Point = {0, 0} The points should be the same but I'm getting a null result. For testing purposes this is happening in the touchesBegan method. Does anyone have any idea where I'm going wrong? Thanks in advance.

• Execute a dll function in ASP.Net Bin not working, II7.

  - by Wayne Lo

  I am developing a remote control application where a client (aspx page in a browser) can request a server to "launch a notepad" (for testing purpose, for real life, turning off a light bulb, etc). So I created a dll with a simple function for launching the notepad (on the server side) and dropped this dll in the root bin folder. It worked fine when the aspx page is running under ASP.NET development server (launched from Visual Studio). But when I tested the same aspx page under a FireFox browser, it did not work (launch the notepad) even though it did call for the same function (I stepped through in debugger). Is this a permission issue? How do I set this up in IIS manager, or even better in web.config? Please help.

• What would you like to see in a book about Rails 3?

  - by Ryan Bigg

  Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

• With Rails 3 routes, how do you only allow a requests from 127.0.0.1?

  - by micah

  I'm writing an app where several of the routes should only be accessible from localhost. It looks like this is possible with the new routing system. http://www.railsdispatch.com/posts/rails-3-makes-life-better This has examples of restricting routes based on IP address, and setting up an IP address blacklist for your routes, but I'm interested in a whitelist with just one IP address. It would be cool if something like this worked: get "/posts" => "posts#show", :constraints => {:ip => '127.0.0.1'} But it didn't. Am I just missing the right syntax?

• How do I load the background image from another page?

  - by bbeckford

  Hi all, I'm creating a page that loads content from other pages using jQuery like this: $('#newPage').load('example.html' + ' #pageContent', function() { loadComplete(); }); That all works fine. Now what I want to do is change the background image of the current page to the background image of the page I'm loading from. This is what I'm doing now but I can't for the life of me get it to work: $.get('example.html', function(data) { var pageHTML = $(data); var pageBody = pageHTML.$('body'); alert(pageBody.attr("background")); }); What am I doing wrong?? Thanks, -Ben

• What is the .NET attribuet to not compile a method is release mode

  - by Russ

  I know that if I have a block of code I don't want compiled when in release mode I can wrap that code block in: #if DEBUG while(true) { Console.WriteLine("StackOverflow rules"); } #endif This will keep this code block from compiling in any mode other than DEBUG. I know there is an attribute that can be placed on an entire method that will do that same, but for the life of me I can't remember what that attribute is. I believe that it’s down the System.Diagnostics namespace, but I'm not really sure. BTW: I'm using .NET 4, but I know this attribute existed in .NET 2 because I have used in in old projects. Thanks

• ASP.Net WebSite Membership AND C# Windows Form Membership

  - by user1638362

  This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

• Getting meaningful error messages from fstream's in C++

  - by Hassan Syed

  What is the best way to get meaningful file access error messages, in a portable way from std::fstreams ? The primitiveness of badbits and failbits is getting to be bit annoying. I have written my own exception hierarchies against win32 and POSIX before, and that was far more flexible than the way the STL does it. I am getting "basic::ios_clear" as an error message from the what method of a downcasted catch (std::exception) of a fstream which has exceptions enabled. This doesn't mean much to me, although I do know what the problem is I'd like my program to be a tad more informative so that when I start deployment a few months later my life will be easier. Is there anything in Boost to extract meaningful messages out of the ofstream's implementation cross platform and cross STL implementation ?

• How do I wrap this BAIL macro in Xcode?

  - by willc2

  I use this little snippet to halt my iPhone app in the simulator. NSAssert((0), @"Bail early while testing"); When I try to make it a #defined macro like this: #define BAILNOW (NSAssert((0), @"Bail early while testing")) I get this build error: error: expected expression before 'do' It seems to be related to the nesting of the NSAssert() macro but I'm at a loss as to how to get around it. Should I dig into the NSAssertionHandler docs or is there some simpler way to halt the app in it's tracks? Or should I just set a breakpoint and get on with my life?

• How does one write extconf.rb files when one extension includes header files from another?

  - by mohawkjohn

  This is a follow-up question for: Multiple Ruby modules under one directory What happens if these extensions include each other? For example, you have the following structure: ext/foo ext/bar In ext/bar/bar.h, you have a #include "foo.h" foo.h and foo.cpp compile to form foo.o, to make life a little more complicated. Finally, it is necessary that foo and bar be separate extensions. How is this managed? I can't figure out how to add ../foo to the search path for bar.h, primarily. Symbolic links seem hack-ish.

• How can I do this Aggrigate, group by, in query in LINQ?

  - by Ólafur Waage

  Please do not give me a full working example, I want to know how this is done rather than to get some code I can copy paste This is the query I need, and can't for the life of me create it in LINQ. SELECT * FROM dbo.Schedules s, dbo.Videos v WHERE s.VideoID = v.ID AND s.ID IN ( SELECT MAX(ID) FROM dbo.Schedules WHERE ChannelID = 1 GROUP BY VideoID ) ORDER BY v.Rating DESC, s.StartTime DESC I have the "IN" query in LINQ I think, it's something like this var uniqueList = from schedule in db.Schedules where schedule.ChannelID == channelID group schedule by schedule.VideoID into s select new { id = s.Max(i => i.ID) }; It is possibly wrong, but now I can not check in another query for this in a where clause uniqueList.Contains(schedule.ID) There is possibly a better way to write this query, if you have any idea I would love some hints. I get this error and it's not making much sense. The type arguments for method 'System.Linq.Queryable.Contains(System.Linq.IQueryable, TSource)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

• What's causing “Session state has created a session id, but cannot save it because the response was

  - by mike nelson

  I'm getting this fault intermittently. I found this link which summarises fairly well what I was able to find on the Google: http://www.wacdesigns.com/2009/02/03/session-state-has-created-a-session-id-but-cannot-save-it-because-the-response-was-already-flushed-by-the-application/ Basically it says you can try setting the web config setting DisplayWhenNewSession, or try kicking the session state thing into life by getting the Session.SessionID in the Session_OnStart. But does anyone: a) have an explanation for this or even better, b) have a tried and tested fix I realise that I can't flush the response after doing anything that would affect the http response header. If I did this it would cause an error every time but this is intermittent. The SessionID should surely be created by ASP.NET at the beginning of the page response automatically, before anything in the ASPX page or the Page_Load (which is where all my flushes are called).

• When is it safe to do a Response.Redirect() without throwing an exception?

  - by DDechant

  I have an intermediary class extending System.Web.UI.Page for all of my pages that require authentication. The class mostly does custom authentication handling. When a user with insufficient access attempts to visit a page, I try to redirect the user back to the login page while preventing any further page events from being executed (ie. Page_load). The first solution that came to mind was the default implementation of Response.Redirect. Of course the downside to this is the possibility of ThreadAbortExceptions being thrown. So my question is this: When (if at all) during the page life cycle is it actually safe to execute Response.Redirect() without ThreadAbortException ever being thrown? public class CustomPage : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); if (!IsValid()) Response.Redirect("login.aspx", true); } }

• Export MySQL Data as Insert Statements

  - by gav

  Hi All, I'm working in Ubuntu with MySql and I also have Query Browser and Administrator installed, I'm not afraid of the command line either if it helps. I want simply to be able to run a query and see a result set but then convert that result set into a series of commands that could be used to create the same rows in a table of an identical schema. I hope the question makes sense, it's quite a simple problem and one that must have been solved but I can't for the life of me work out where this kind of conversion is made available. Thanks in advance, Gav

• How to keep up the interest in job?

  - by stranger

  Hi, I have been working as Software Developer for 6+ yrs. And I have worked from start ups to big companies. I always feel some elements missing in me and those are interest, passion etc. In short, I don't feel motivated while coming to work. This makes me think how my work-life balance will look like once I reach at more responsible positions. I don't want to change my field and I feel blessed as well but I think I am not working passionately for my learning, future growth, improvement, skills etc. Any pointers will be highly appreciated. Thx

• How to handle HTML rendering in C# WebBrowser control?

  - by sashaeve

  Is any way to handle a moment when HTML page is rendered on C# WebBrowser control? Edit. WebBrowser control has many events such as Navigated, GotFocus etc. I need to handle an event when HTML is rendered inside the control. Just wondered is it possible. For example, in asp.net we have OnRender, OnInit, OnLoad, OnPreLoad events which form web-page life-cycle. OnLoad in asp.net is something like Navigated for WebBrowser, the idea is to handle event similar to OnRender.
