  • PHP is not returning me a number type

    - by Tristan
    Hello, i tryed to follow that great tutorial (STAR rating with css : http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) but i've just a big problem : When i do <span class="stars">1.75</span> or $foo='1.75'; echo '<span class="stars">'.$foo.'</span> the stars is correctly shown, but as soon as i do : while($val = mysql_fetch_array($result)) { $average = ($val['services'] + $val['serviceCli'] + $val['interface'] + $val['qualite'] + $val['rapport'] ) / 5 ; <span class="stars">.$average.</span> } the stars stops working i double checked the data type in mysql : they're all TINYINT(2) and i tryed that : $average = intval($average); but it's still not working, Thank you

  • Speed up math code in C# by writing a C dll?

    - by Projectile Fish
    I have a very large nested for loop in which some multiplications and additions are performed on floating point numbers. for (int i = 0; i < length1; i++) { s = GetS(i); c = GetC(i); for(int j = 0; j < length2; j++) { double oldU = u[j]; u[j] = c * oldU + s * omega[i][j]; omega[i][j] = c * omega[i][j] - s * oldU; } } This loop is taking up the majority of my processing time and is a bottleneck. Would I be likely to see any speed improvements if I rewrite this loop in C and interface to it from C#?

  • Are there any easy ways to generate OpenGL code for drawing shapes from a GUI?

    - by Sam152
    I have enjoyed learning to use OpenGL under the context of games programming, and I have experimented with creating small shapes. I'm wondering if there are any resources or apps that will generate code similar to the following with a simple paint-like interface. glColor3f(1.0, 0.0, 0.0); glBegin(GL_LINE_STRIP); glVertex2f(1, 0); glVertex2f(2, 3); glVertex2f(4, 5); glEnd(); I'm having trouble thinking of the correct dimensions to generate shapes and coming up with the correct co-ordinates.

  • Change Gmail message routing on individual mailboxes

    - by citadelgrad
    We are using dual delivery for one of our Google Apps doamins and need to be able to disable mail delivery to the Gmail account. You can manually update the settings on a per user basis through the Admin interface by unchecking the box next to "Google Apps Email" in the Email routing section. From the Google Apps API documentation for the python library it does not appear that I programmatically disable the email routing for "Google Apps Email" on a per user basis. Does anyone know if it's possible? The only routing related method I can find is at the Domain level and not the user level. gdata.apps.adminsettings.service Thank you!

  • Memory management technique for Objective-C iVars/properties

    - by David Rea
    Is the following code doing anything unnecessary? @interface MyClass { NSArray *myArray; } -(void)replaceArray:(NSArray *)newArray; @implementation MyClass -(void)replaceArray:(NSArray *)newArray { if( myArray ) { [myArray release]; myArray = nil; } myArray = [[NSArray alloc] initWithArray: newArray]; } @end What if I made the following changes: 1) Made myArray a property: @property (nonatomic, retain) NSArray myArray; 2) Changed the assignment to: self.myArray = [NSArray arrayWithArray: newArray]; Would that allow me to remove the conditional?

  • Why am I getting "too many include files : depth = 1024"?

    - by BeeBand
    I'm using Visual Studio 2008 Express edition, and keep getting the following error: "Cascadedisplay.h(4) : fatal error C1014: too many include files : depth = 1024. Obviously I'm doing something very wrong with include files, but I just can't see what. Basically, I have an interface class, StackDisplay, from which I want to derive CascadeDisplay in another file: #if !defined __BASE_STACK_DISPLAY_H__ #define __BASE_STACK_DISPAY_H__ #include <boost\shared_ptr.hpp> #include "CascadeDisplay.h" namespace Sol { class StackDisplay { public: virtual ~StackDisplay(); static boost::shared_ptr<StackDisplay> make_cascade_display(boost::shared_ptr<int> csptr) { return boost::shared_ptr<StackDisplay>(new CascadeDisplay(csptr)); } }; } #endif and then in CascadeDisplay.h: #if !defined __CASCADE_DISPLAY_H__ #define __CASCADE_DISPAY_H__ #include "StackDisplay.h" #include <boost\shared_ptr.hpp> namespace Sol { class CascadeDisplay: public StackDisplay { public: CascadeDisplay(boost::shared_ptr<int> csptr){}; }; } #endif So what's up with that?

  • How extension methods work in background ?

    - by Freshblood
    I am just cuirous about behind of extension method mechanism.Some questions and answer appear in my mind. MyClass.OrderBy(x=>x.a).OrderBy(x=>x.b); I was guessing that mechanism was first orderby method works and order them by a member then returns sorted items in IEnumarable interface then next Orderby method of IEnumarable Order them for b paramater.But i am wrong when i look at this linq query. MyClass.Orderby(x=>x.a).ThenOrderBy(x=>x.b); this is slightly different and tells me that i am wrong.Because this is not ordering by a then b and not possible to have such result if i was right.This get me confuse enough... Similiar structure is possible to write withot extension methods as first query but second is not possible.This prove i am wrong . Can u explain it ?

  • Getting true video Height/Width from ASF videos

    - by David
    I am trying to convert an ASF video with FFMPEG using an interface called mediahandler. The issue is, the metadata on the ASF video appears to be corrupt. It states that the video is 640x240, and 4:3 aspect ratio. The aspect ratio is correct, but obviously the resolution is not. This causes the converter to incorrectly scale the video, because it uses the resolution to determine the original aspect ratio. I am able to get the aspect ratio metadata, but I'm not sure this solves the issue, because I would think that if the resolution could be incorrect, then so could the aspect ratio metadata. So, is there any way to get the actual height/width? It appears that players like VLC have no issue with this. How do I do such a thing w/ FFMPEG?

  • SOAP - What's the point?

    - by DanSingerman
    I mean, really, what is the point of SOAP? Web services have been around for a while, and for a while it seemed that the terms 'SOAP' and 'Web service' were largely interchangeable. However SOAP always seemed unwieldy and massively overcomplicated to me. Then REST came along, and suddenly web services made sense. As Joel Spolsky says, give a programmer a REST URL, and they can start playing with the service right away, figuring it out. SOAP is obfuscated behind WSDLs and massively verbose XML, and despite being web based, you can't do anything as simple as access a SOAP service with a web browser. So the essence of my question is: Are there any good reasons to ever choose SOAP over REST? Are you working with SOAP now? Would it be better if the interface was REST? Am I wrong?

  • Mock a void method which change the input value

    - by Kar
    Hi, How could I mock a void method with parameters and change the value parameters? My void method looks like this: public interface IFoo { void GetValue(int x, object y) // takes x and do something then access another class to get the value of y } I prepared a delegate class: private delegate void GetValueDelegate(int x, object y); private void GetValue(int x, object y) { // process x // prepare a new object obj if (y == null) y = new Object(); if (//some checks) y = obj; } I wrote something like this: Expect.Call(delegate {x.GetValue(5, null);}).Do (new GetValueDelegate(GetValue)).IgnoreArguments().Repeat.Any(); But seems like it's not working. Any clue on what could be wrong?

  • MustOverride Shared Methods in .Net

    - by Ben
    Hi I have a few class's that inherit from a base class. I want to enforce that all of these Class's implement a shared method foo(). I am not able to create the following on the base class Public MustOvveride Shared Sub foo() as this is not allowed. I also cant create an Interface that defines a Shared Sub Foo() and implement that in my derrived class's, as this also is not allowed. Does anyone know how i should implement this? p.s i realise my example is in VB and i have also tagged C#, the same problem applies to both languages and presumably the same fix would apply.

  • Get touches from UIScrollView

    - by Peter Lapisu
    Basically i want to subclass UIScrollView and hande the touches, however, the touch methods dont get called (i searched the web for a solution and i found out people pointing to override the hit test, what i did, but with no result :( ) .h @interface XScroller : UIScrollView @end .m - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView *result = nil; for (UIView *child in self.subviews) { if ([child pointInside:point withEvent:event]) { if ((result = [child hitTest:point withEvent:event]) != nil) { break; } } } return result; } - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"BEGAN"); [super touchesBegan:touches withEvent:event]; } - (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"MOVED"); [super touchesMoved:touches withEvent:event]; } - (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"ENDED"); [super touchesEnded:touches withEvent:event]; } - (void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"CANCELED"); [super touchesCancelled:touches withEvent:event]; } none of the - (void) touches* methods get called, the scrolling works ok

  • Can i have a negative value as constant expression in Scala?

    - by Klinke
    I have an Java-Annotation that return a double value: @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface DoubleValue { double value(); } When i try to attach the annotation to a field in a scala class and the value is negativ like here: class Test { @DoubleValue(-0.05) var a = _ } i get an compiler error with the message: "annotation argument needs to be a constant; found: 0.05.unary_-". I understood that i need a numerical literal and i looked into the Scala Language Specification and it seems, that the - sign is only used for the exponent but not for the mantissa. Does someone has an idea how i can have a negative value as runtime information using annotations? Thanks, Klinke

  • How do I use Amazon's new RRS for S3?

    - by pbarney
    Reduced Redundancy Storage (RRS) is a new service from Amazon that is a bit cheaper than S3 because there is less redundancy. However, I can not find any information on how to specify that my data should use RRS rather than standard S3. In fact, there doesn't seem to be any website interface for an S3 services. If I log into AWS, there are only options for EC2, Elastic MapReduce, CloudFront and RDS, none of which I use. Any insight? Thanks.

  • Define the base class or base functionality of a dynamic proxy (e.g. Castle, LinFu)

    - by Graham
    Hi, I've asked this in the NHibernate forumns but I think this is more of a general question. NHibernate uses proxy generators (e.g. Castle) to create its proxy. What I'd like to do is to extend the proxy generated so that it implements some of my own custom behaviour (i.e. a comparer). I need this because the following standard .NET behaviour fails to produce the correct results: //object AC is a concrete class collection.Contains(AC) = true //object AP is a proxy with the SAME id and therefore represents the same instance as concrete AC collection.Contains(AP) = false If my comparer was implemented by AP (i.e. do id's match) then collection.Contains(AP) would return true, as I'd expect if proxies were implicit. (NB: For those who say NH inherits from your base class, then yes it does, but NH can also inherit from an interface - which is what we're doing) I'm not at all sure this is possible or where to start. Is this something that can be done in any of the common proxy generators that NH uses?

  • Buy or build tool for Data Reporting ?

    - by Manoj
    We have been asked to provide a data reporting solution. The followng are the requirements: i. The client has a lot of data which is generated everyday as an outcome of the tests they run. These tests are run at several sites and they get automatically backed up into a central server. ii. They already have perl scripts which post process them and generates excel based reports. iii. They need a web based interface for comparing those reports and they need to mark and track issues which might be present in those data. I am confused if we should build our own tool for this or we should go for already exiting tool(any suggestions?). Can you please provide supportive arguments for the decision that you would suggest?

  • Recreating iPhone stock application with nested views

    - by john
    I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

  • Question About Abstract Classes?

    - by IbrarMumtaz
    URL: Link (1) According to this wesbite .. you cannot implement Abstract classes but derive from them. This makes sense and I have read this many times. Like an interface, you cannot implement an instance of an abstract class, however you can implement methods, fields, and properties in the abstract class that can be used by the child class. But on MSDN URL: TextWriter CLass on MSDN TextWriter is an abstract class but it has two constructors defined ... and according to the MS 70-536 book, the following statement is valid: TextWriter tw = new File.CreateText("myFile.Txt") The static file class and it's CreateText method is fine by me as I have studied it on MSDN but can somebody explain this little contradiction I have found? Surely I am not the first? Why is instantaion of base abstract classes possible????

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • StructureMap: Calling repository constructor based on RouteData

    - by FreshCode
    I'm implementing a multi-tenant ASP.NET MVC application and using StructureMap for DI where my repositories depend on an ITenantContext interface, which depends on RouteData (or a base controller property). How do I tell StructureMap to construct TenantContext(tenantID); where tenantID is derived from my RouteData or some base controller property? Given the following route: {tenant}/{controller}/{action} My base controller retrieves and stores the correct Tenant based on the {tenant} URL parameter. Using Tenant, a repository with an ITenantContext can be constructed to retrieve only data that is relevant to that tenant. Based on the other DI questions, AbstractFactory could be a solution?solution?

  • Block all other input to an application and control it from a wrapper in Java

    - by Oren
    I have a windows application which has a complex GUI that I would like to hide from users. In order to do this, I would like to create a wrapper with an extremely simple interface that overlays this application and automates a number of actions when a user clicks a single button on the wrapper. (I hope "wrapper" is the proper term.) Is it possible to use Java to block input to the underlying application so that users cannot inadvertently mess up the automation? How would I go about this? Also, how can I automate key presses and clicks to the application without hijacking the mouse? Is this possible in Java? I have looked at java.awt.Robot, but it appears to hijack the mouse. I have also looked at AutoIT, but it too hijacks the mouse and does not integrate with Java. Neither of these options seem powerful enough for what I need, but I do not know how else to proceed.

  • Incompatible classes when loading SWF

    - by Bart van Heukelom
    I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?

  • Generate Windows .lnk file with PHP

    - by Andrei
    Hello, I'm working on a project which involves an FTP server running ProFTPd and a PHP/MySQL backend that creates accounts for users. Upon the creation of accounts, users are sent e-mails with their account details and instructions for downloading FileZilla or CyberDuck, depending on their OS, detected via user-agent string. To make things easier for novices, I thought of having .lnk files generated for FileZilla with the account logins details as parameters, so they would just have to click on the .lnk files to open up the server. This is not crucial feature but more of a technical challenge. My questions are : is this even feasible ? are there any alternatives (eg. generating a .bat with a script pointing to the Filezilla executable ?) are there any issues, perhaps with relative / absolute paths pointing to the executable ? to go even further, what would be the simplest way of providing users with software with FTP access on a single account / single server (web interface is not an option).

  • Using GET instead of POST to delete data behind authenticated pages

    - by Matt Spradley
    I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?

  • CLI design and implementation?

    - by Majid
    I am developing a time management tool for my personal use. I prefer using keyboard over mouse, and on the interface have a general purpose text box which will act like a command line. I have just started thinking about what commands I need, what to use for the command names, how to pass in switches and parameters, and so forth. I wonder if some of you have come across a good read along these lines; something that describes the choices you have for designing a cli, and how those affect the complexity of the interpreter, and extendability of the commands. It makes no difference if the descriptions are language-specific or in general terms. However, my implementation will be with javascript. Thank you.
