  • Using Cucumber With Modular Sinatra Apps

    - by Rob Conery
    I'm building out a medium-sized application using Sinatra and all was well when I had a single app.rb file and I followed Aslak's guidance up on Github: http://wiki.github.com/aslakhellesoy/cucumber/sinatra As the app grew a bit larger and the app.rb file started to bulge, I refactored out a lot of of the bits into "middleware" style modules using Sinatra::Base, mapping things using a rack-up file (config.ru) etc. The app works nicely - but my specs blew up as there was no more app.rb file for webrat to run against (as defined in the link above). I've tried to find examples on how to work this - and I think I'm just not used to the internal guts of Cuke just yet as I can't find a single way to have it cover all the apps. I tried just pointing to "config.ru" instead of app.rb - but that doesn't work. What I ended up doing - which is completely hackish - is to have a separate app.rb file in my support directory, which has all the requires stuff so I can at least test the model stuff. I can also specify routes in there - but that's not at all what I want to do. So - the question is: how can I get Cucumber to properly work with the modular app approach?

  • How can I emulate the ASP.NET Ajax UpdatePanel when using ASP.NET MVC?

    - by Gary McGill
    In "traditional" ASP.NET (Web Forms), the UpdatePanel control lets you do a partial refresh of a part of a page. You don't need to write much code to hook this up. What's the equivalent in ASP.NET MVC? I'm guessing I'd need to use a partial view for the bit that I want to update, then on the client side retrieve that HTML and pump it into the innerHtml of the correct DIV? A tutorial/example would be helpful...

  • How do I use a file grep comparison inside a bash if/else statement?

    - by openid_kenja
    When our server comes up we need to check a file to see how the server is configured. We want to search for the following string inside our /etc/aws/hosts.conf file: MYSQL_ROLE=master Then, we want to test whether that string exists and use an if/else statement to run one of two options depending on whether the string exists or not. What is the BASH syntax for the if statement? if [ ????? ]; then #do one thing else #do another thing fi

  • JQueryUI with Google's CDN help

    - by TenaciousImpy
    Hi, I'm having trouble loading JQueryUI from Google's CDN. I've got an ASP.NET application that and am using this to call the scripts: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js" type="text/javascript"></script> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/ui-darkness/jquery-ui.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> $(function() { $("#accordion").accordion(); }); </script> </asp:Content> I then have a test accordion: <div id="accordion"> <h3><a href="#">First header</a></h3> <div>First content</div> <h3><a href="#">Second header</a></h3> <div>Second content</div> </div> However, this doesn't work. I used Chrome's Dev tool and I get this error: Uncaught Error: The 'accordion' plugin requires Sys.scripts.ExtendedAccordion to be loaded with a call to Sys.require() first I'm also using MS' Ajax CDN in my masterpage, so could that be causing a problem? Thanks

  • How can I draw a Rectangle on a PictureBox?

    - by TooFat
    I am trying to just draw a Rectangle on a PictureBox that is on a Form. Writing text like shown here works fine. private void pictureBox1_Paint(object sender, PaintEventArgs e) { using (Font myFont = new Font("Arial", 14)) { e.Graphics.DrawString("Hello .NET Guide!", myFont, Brushes.Green, new Point(2, 2)); } } but when I try to draw a rectangle like so nothing shows up. private void pictureBox1_Paint(object sender, PaintEventArgs e) { Rectangle rect = new Rectangle(); rect.Location = new Point(25, 25); rect.Width = 50; using (Pen pen = new Pen(Color.Red, 2)) { e.Graphics.DrawRectangle(pen, rect); } } What am I missing?

  • c# Named Pipe Asynchronous Peeking

    - by KJ Tsanaktsidis
    Hey all, I need to find a way to be notified when a System.IO.Pipe.NamedPipeServerStream opened in asynchronous mode has more data available for reading on it- a WaitHandle would be ideal. I cannot simply use BeginRead() to obtain such a handle because it's possible that i might be signaled by another thread which wants to write to the pipe- so I have to release the lock on the pipe and wait for the write to be complete, and NamedPipeServerStream doesnt have a CancelAsync method. I also tried calling BeginRead(), then calling the win32 function CancelIO on the pipe if the thread gets signaled, but I don't think this is an ideal solution because if CancelIO is called just as data is arriving and being processed, it will be dropped- I still wish to keep this data, but process it at a later time, after the write. I suspect the win32 function PeekNamedPipe might be useful but i'd like to avoid having to continuously poll for new data with it. In the likley event that the above text is a bit unclear, here's roughly what i'd like to be able to do... NamedPipeServerStream pipe; ManualResetEvent WriteFlag; //initialise pipe lock (pipe) { //I wish this method existed WaitHandle NewDataHandle = pipe.GetDataAvailableWaithandle(); Waithandle[] BreakConditions = new Waithandle[2]; BreakConditions[0] = NewDataHandle; BreakConditions[1] = WriteFlag; int breakcode = WaitHandle.WaitAny(BreakConditions); switch (breakcode) { case 0: //do a read on the pipe break; case 1: //break so that we release the lock on the pipe break; } }

  • Sharepoint, ajax and page title

    - by drax
    Hi, I have strange problem with sharepoint and ajax functionality. We have an UpdatePanel placed inside webpart. When partial postback occurs, page title gets missing. We have found that temporary partial solution is to write title element into one line and not use any spaces or controls inside it..not even a literal control. But we need some way to provide sommon title for all pages, so title would look like this: My default title - Current page title Any ideas how to solve this?

  • Did anyone created the Java Code Formatter Profile for Eclipse IDE that conforms to the Android Code

    - by yvolk
    Android Code Style Guide defines "Android Code Style Rules". To conform to these rules one have to change quite a number of settings of the Java Code Formatter (Window-Preferences-Java-Formatter) default profile (in Eclipse IDE). Did anyone managed to configure the formatter to follow the "Android Code Style Rules" already? PS: I've tried to do this myself but I've found that there are too many formatter options available, and most of them are not mentioned in the Code Style Guide :-(

  • Processing XML file with Huge data

    - by Manish Dhanotiya
    Hi,be m I am working on an application which has below requiements - 1. Download a ZIP file from a server. 2. Uncompress the ZIP file, get the content (which is in XML format) from this file into a String. 3. Pass this content into another method for parsing and further processing. Now, my concerns here is the XML file may be of Huge size say like '100MB', and my JVM has memory of only 512 MB, so how can I get this content into Chunks and pass for Parsing and then insert the data into PL/SQL tables. Since there can be multiple requests running at the same time and considering 512MB of memory what will be the best possible to process this. How I can get the data into Chunks and pass it as Stream for XML parsing. I googled on this, but didnt find any implementation. :( Thanks,

  • sending data to the server via port 5555 C#

    - by numerical25
    I am wanting to send some data to a server from a client application to the server via port 5555. I don't have a window's server. My question is if I purchase a .Net Framework hosting service. Would I be able to connect the client application to this server. and could I do it by sending a Post. I am new to this, so excuse me if it doesn't entire make sense. but I am looking for just some little direction. If someone could explain what port 5555 is used for that would be great.

  • How do I write an IF ELSE to check string contents of an array?

    - by Michael Robinson
    I'm trying to write an IF ELSE statement to enable shipping, If user doesn't add an address the array contents remain as "-" & "-" for the two items in the array. I want to check to see if those are in the array, if they are then I want to enableshipping. Here is the code for getting the array: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullFileName = [NSString stringWithFormat:@"%@/arraySaveFile", documentsDirectory]; NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName]; How do I write this first line to look for the "-" & "-"? if ([fullFileName isEqualToString:@"-","-"]) { [nnNEP EnableShipping]; } else { [nnNEP DisableShipping]; } Thanks, michael

  • How do I manually Dispose RSACryptoServiceProvider?

    - by phq
    I have read on MSDN(see Important note) that RSACryptoServiceProvider must be disposed. They give the example: using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider()) Now I'm trying to include RSACryptoServiceProvider into MyClass making use of it in several Methods. With this setup I cannot use the using statement. Instead I try to call the .Dispose() Method of the RSACryptoServiceProvider object at a suitable time but then I get the compile error message: `System.Security.Cryptography.AsymmetricAlgorithm.Dispose(bool)' is inaccessible due to its protection level Is RSACryptoServiceProvider not supposed to be used longer than one function call(using the using statement)? How can I fix this, is not making the Dispose call an option?

  • Why is APC (PHP Accelerator) Only caching apc.php?

    - by amvx
    I installed PHP5,APC and XDEBUGGER with the install script found here: Dreamhost PHP+APC Install Instructions/Script All systems seem to be working... except... I added the apc.php to see the caching stats of APC (GUI Interface), and it showed that only apc.php file was being cached despite having installed wordpress and prestashop under the same domain, installing and running those php scripts. I wonder if I did something wrong... but my php5 is running as a cgi/fastcgi. I think I might have read somewhere about there being some issue with this. Not sure. Any help is of coursed appreciated.

  • Is there a way to determine which service does an outgoing connection?

    - by fluxtendu
    I'm redoing my firewall configuration with more restrictive policies and I would like to determine the provenance (and/or destination) of some outgoing connections. I have an issue because they come from svchost.exe and go to web content/application delivery providers - or similar: 5 IP in range: 82.96.58.0 - 82.96.58.255 --> Akamai Technologies akamaitechnologies.com 3 IP in range: 93.150.110.0 - 93.158.111.255 --> Akamai Technologies akamaitechnologies.com 2 IP in range: 87.248.194.0 - 87.248.223.255 --> LLNW Europe 2 llnw.net 205.234.175.175 --> CacheNetworks, Inc. cachefly.net 188.121.36.239 --> Go Daddy Netherlands B.V. secureserver.net So is it possible to know which service does a particular connection? Or what's your recommendation about the rules applied to these ones? (Comodo Firewall & Windows 7)

  • C# Fun with Generics - Mutual Dependencies

    - by Kenneth Cochran
    As an experiment I'm trying to write a generic MVP framework. I started with: public interface IPresenter<TView> where TView: IView<IPresenter<... { TView View { get; set;} } public interface IView<TPresenter> where TPresenter:IPresenter<IView<... { TPresenter Presenter { get; set; } } Obviously this can't work because the types of TView and TPresenter can't be resolved. You'd be writing Type<Type<... forever. So my next attempt looked like this: public interface IView<T> where T:IPresenter { ... } public interface IView:IView<IPresenter> { } public interface IPresenter<TView> where TView: IView { ... } public interface IPresenter: IPresenter<IView> { ... } This actually compiles and you can even inherit from these interfaces like so: public class MyView : IView, IView<MyPresenter> { ... } public class MyPresenter : IPresenter, IPresenter<MyView> { ... } The problem is in the class definition you have to define any members declared in the generic type twice. Not ideal but it still compiles. The problem's start creeping up when you actually try to access the members of a Presenter from a View or vice versa. You get an Ambiguous reference when you try to compile. Is there any way to avoid this double implementation of a member when you inherit from both interfaces? Is it even possible to resolve two mutually dependent generic types at compile time?

  • How do I avoid the loader lock?

    - by Mark0978
    We have a managed app, that uses an assembly. That assembly uses some unmanaged C++ code. The Managed C++ code is in a dll, that depends on several other dlls. All of those Dlls are loaded by this code. (We load all the dll's that ImageCore.dll depends on first, so we can tell which ones are missing, otherwise it would just show up as ImageCore.dll failed to load, and the log file would give no clues as to why). class Interop { private const int DONT_RESOLVE_DLL_REFERENCES = 1; private static log4net.ILog log = log4net.LogManager.GetLogger("Imagecore.NET"); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr LoadLibraryEx(string fileName, IntPtr dummy, int flags); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr FreeLibrary(IntPtr hModule); static private String[] libs = { "log4cplus.dll", "yaz.dll", "zlib1.dll", "libxml2.dll" }; public static void PreloadAssemblies() { for (int i=0; i < libs.Length; ++i) { String libname = libs[i]; IntPtr hModule = LoadLibraryEx(libname, IntPtr.Zero, DONT_RESOLVE_DLL_REFERENCES); if(hModule == IntPtr.Zero) { log.Error("Unable to pre-load '" + libname + "'"); throw new DllNotFoundException("Unable to pre-load '" + libname + "'"); } else { FreeLibrary(hModule); } } IntPtr h = LoadLibraryEx("ImageCore.dll", IntPtr.Zero, 0); if (h == IntPtr.Zero) { throw new DllNotFoundException("Unable to pre-load ImageCore.dll"); } } } And this code is called by public class ImageDoc : IDisposable { static ImageDoc() { ImageHawk.ImageCore.Utility.Interop.PreloadAssemblies(); } ... } Which is static constructor. As near as I can understand it, as soon as we attempt to use an ImageDoc object, the dll that contains that assembly is loaded and as part of that load, the static constructor is called which in turn causes several other DLLs to be loaded as well. What I'm trying to figure out, is how do we defer loading of those DLLs so that we don't run smack dab into this loader lock that is being kicked out because of the static constructor. I've pieced this much together by looking at: http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/dd192d7e-ce92-49ce-beef-3816c88e5a86 http://msdn.microsoft.com/en-us/library/aa290048%28VS.71%29.aspx http://forums.devx.com/showthread.php?t=53529 http://www.yoda.arachsys.com/csharp/beforefieldinit.html But I just can't seem to find a way to get these external DLLs to load without it happening at the point the class is loading. I think I need to get these LoadLibrary calls out of the static constructor, but don't know how to get them called before they are needed (except for how it is done here). I would prefer to not have to put this kind of knowledge of the dlls into every app that uses this assembly. (And I'm not sure that would even fix the problem.... The strange thing is that the exception only appears to be happening while running within the debugger, not while running outside the debugger.

  • How effecient is a details table?

    - by Jeffrey Lott
    At my job, we have pseudo-standard of creating one table to hold the "standard" information for an entity, and a second table, named like 'TableNameDetails', which holds optional data elements. On average, for every row in the main table will have about 8-10 detail rows in it. My question is: What kind of performance impacts does this have over adding these details as additional nullable columns on the main table?

  • Help with MySQL query - Product orders report without duplicate shipping charges

    - by Paul
    Hello, I have an issue creating a custom report for an e-commerce store running on osCommerce. The client wants the report to have the following columns: Date, Order ID, Product Class, Product Price, Product Tax, Shipping, Order Total The criteria for generating the report are Date Range and Product Class (Textbooks for example) The client wants the report to list each Textbook purchased on its own line. Orders with multiple textbooks would display a separate line for each Textbook in the order. I have it all working except for one part: the shipping amount is order-specific (based on the order total), not product-specific, and is displaying for each product. I need it to display only for the first product of each order, so it is not counted more than once. My current query is: SELECT op.date_funds_captured as 'Date', op.orders_id as 'Order ID', pc.class as 'Product Class', round(op.products_price,2) as 'Product Price', round(op.products_tax*op.products_price/100,2) as 'Product Tax', round(otship.value,2) as 'Shipping', round(ot.value,2) as 'Order Total' from orders_products op, orders_total ot, orders_total otship, productclasses pc, products p where ot.orders_id = op.orders_id and ot.class='ot_total' and op.orders_id = otship.orders_id and otship.class = 'ot_shipping' and p.products_class_id = pc.id and op.products_id = p.products_id and pc.id = 1 pc.id = 1 -- Product class = Textbook Here is an example of the current report output. You can see the problem with order 2256 showing the shipping value three times instead of once: Date Order Product Class Price Tax Shipping Total 2010-01-04 2253 Textbook 24.95 2.43 10.03 37.41 2010-01-04 2256 Textbook 34.95 0.00 18.09 240.37 2010-01-04 2256 Textbook 55.50 0.00 18.09 240.37 2010-01-04 2256 Textbook 36.95 0.00 18.09 240.37 2010-01-04 2258 Textbook 55.50 5.41 12.17 124.24 Please help!!!
