  • WAMP not sending file headers (content-type) correctly

    - by Industrial
    Hi! I cant get a PHP file to send correct headers at my WAMP server. Wouldn't be a problem normally except that is phpMyAdmin that is freaking out right now. Here's the row that the file that merges the css files together in phpmyadmin uses to send the output as CSS. header('Content-Type: text/css; charset=UTF-8'); I have also putted a .htaccess file in the phpmyadmin directory: AddType text/css .css Neither is working. What can I do to make sure that this file is interpreted as a CSS by firefox?

  • Referring to the type of an inner class in Scala

    - by saucisson
    The following code tries to mimic Polymorphic Embedding of DSLs: rather than giving the behavior in Inner, it is encoded in the useInner method of its enclosing class. I added the enclosing method so that user has only to keep a reference to Inner instances, but can always get their enclosing instance. By doing this, all Inner instances from a specific Outer instance are bound to only one behavior (but it is wanted here). abstract class Outer { sealed class Inner { def enclosing = Outer.this } def useInner(x:Inner) : Boolean } def toBoolean(x:Outer#Inner) : Boolean = x.enclosing.useInner(x) It does not compile and scala 2.8 complains about: type mismatch; found: sandbox.Outer#Inner required: _81.Inner where val _81:sandbox.Outer From Programming Scala: Nested classes and A Tour of Scala: Inner Classes, it seems to me that the problem is that useInnerexpects as argument an Inner instance from a specific Outer instance. What is the true explanation and how to solve this problem ?

  • Firefox fails to detect content type set by PHP

    - by Ying
    Hi all, I want a php page to 'display' a pdf. Here is the code: <?php header("Content-type: application/pdf"); readfile('Reportage - Berlin.pdf'); //tried echo(readfile(...)) as well ?> Not very complicated I think, but somehow firefox cant detect that this is a pdf. This works in Safari but in firefox, i get a prompt to download the file, so i get like a pdftest.php file. I know im getting my file because if I rename the extension to pdf, i can open it. This seems too simple! am i missing something?

  • Assigning a vector of one type to a vector of another type

    - by deworde
    Hi, I have an "Event" class. Due to the way dates are handled, we need to wrap this class in a "UIEvent" class, which holds the Event, and the date of the Event in another format. What is the best way of allowing conversion from Event to UIEvent and back? I thought overloading the assignment or copy constructor of UIEvent to accept Events (and vice versa)might be best.

  • Is the WebAii test automation framework dead?

    - by RyanW
    Is the WebAii framework still available and free? Am I just missing it? After putting it off for too long, I've finally started automated UI testing on my current project. I had WebAii from ArtOfTest on my list to look at, but it looks like it's been killed off by Telerik and now they're asking $1500 for their new WebUI test studio. I can't find anything definitive on Telerik's site, too much marketing. But, it seems to be pretty clear.

  • Dynamically set generic type argument

    - by fearofawhackplanet
    Following on from my question here, I'm trying to create a generic value equality comparer. I've never played with reflection before so not sure if I'm on the right track, but anyway I've got this idea so far: bool ContainSameValues<T>(T t1, T t2) { if (t1 is ValueType || t1 is string) { return t1.Equals(t2); } else { IEnumerable<PropertyInfo> properties = t1.GetType().GetProperties().Where(p => p.CanRead); foreach (var property in properties) { var p1 = property.GetValue(t1, null); var p2 = property.GetValue(t2, null); if( !ContainSameValues<p1.GetType()>(p1, p2) ) return false; } } return true; } This doesn't compile because I can't work out how to set the type of T in the recursive call. Is it possible to do this dynamically at all? There are a couple of related questions on here which I have read but I couldn't follow them enough to work out how they might apply in my situation.

  • How do you unit test a class that's meant to talk to data?

    - by Arda Xi
    I have a few repository classes that are meant to talk to different kinds of data, deriving from an IRepository interface laid out like so: In implementations, the code talks to a data source, be this a directory of XML files or a database or even just a cache. Is it possible to reliably unit test any of these implementations? I don't see a mock implementation working, because then I'm only testing the mock code and not the actual code.

  • NHibernate How to specify custom sql type only in production

    - by Davide Orazio Montersino
    I am saving binary files into a Sql Server 2005 Db using Fluent NHibernate. However, I am using SQLite to run my (pseudo) Unit Tests. I need to use a custom Sql type for Ms Sql, but it would throw an error on SqlLite. What strategies can I use? This is the Map file: public class BinaryFile { public BinaryFile() { m.Map(x => x.BinaryData);//.CustomSqlType("varbinary(MAX)"); m.Map(x => x.ContentType); m.Map(x => x.FileName); m.Map(x => x.FileSize); } }

  • Using type hints in Clojure for Java return values

    - by mikera
    I'm working on some Java / Clojure interoperability and came across a reflection warning for the following code: (defn load-image [resource-name] (javax.imageio.ImageIO/read (.getResource (class javax.imageio.ImageIO) resource-name))) => Reflection warning, clojure/repl.clj:37 - reference to field read can't be resolved. I'm surprised at this because getResource always returns a URL and I would therefore expect the compiler to use the appropriate static method in javax.imageio.ImageIO/read. The code works fine BTW so it is clearly finding the right method at run time. So two questions: Why is this returning a reflection warning? What type hint do I need to fix this?

  • Unity: Replace registered type with another type at runtime

    - by gehho
    We have a scenario where the user can choose between different hardware at runtime. In the background we have several different hardware classes which all implement an IHardware interface. We would like to use Unity to register the currently selected hardware instance for this interface. However, when the user selects another hardware, this would require us to replace this registration at runtime. The following example might make this clearer: public interface IHardware { // some methods... } public class HardwareA : IHardware { // ... } public class HardwareB : IHardware { // ... } container.RegisterInstance<IHardware>(new HardwareA()); // user selects new hardware somewhere in the configuration... // the following is invalid code, but can it be achieved another way? container.ReplaceInstance<IHardware>(new HardwareB()); Can this behavior be achieved somehow? BTW: I am completely aware that instances which have already been resolved from the container will not be replaced with the new instances, of course. We would take care of that ourselves by forcing them to resolve the instance once again.

  • Constructor Type Coercion in C++

    - by Robert Mason
    Take the following class: class mytype { double num; public: mytype(int a) { num = sqrt(a); } void print() { cout << num; } } Say there is a method which takes a mytype: void foo(mytype a) { a.print(); } Is it legal c++ (or is there a way to implement this) to call foo(4), which would (in theory) output 2? From what I can glean you can overload type casts from a user defined class, but not to. Can constructor do this in a standards-compliant manner (assuming, of course, the constructor is not explicit). Hopefully there is a way to in the end have this legal: int a; cin >> a; foo(a); Note: this is quite obviously not the actual issue, but just an example for posting purposes. I can't just overload the function because of inheritance and other program-specific issues.

  • Avoid incompatible pointer warning when dealing with double-indirection

    - by fnawothnig
    Assuming this program: #include <stdio.h> #include <string.h> static void ring_pool_alloc(void **p, size_t n) { static unsigned char pool[256], i = 0; *p = &pool[i]; i += n; } int main(void) { char *str; ring_pool_alloc(&str, 7); strcpy(str, "foobar"); printf("%s\n", str); return 0; } ... is it possible to somehow avoid the GCC warning test.c:12: warning: passing argument 1 of ‘ring_pool_alloc’ from incompatible pointer type test.c:4: note: expected ‘void **’ but argument is of type ‘char **’ ... without casting to (void**) (or simply disabling the compatibility checks)? Because I would very much like to keep compatibility warnings regarding indirection-level...

  • How to determine MIME Type set by htaccess in PHP

    - by Ed Marty
    I have a .htaccess file set up to define specific MIME types in directory root/a/b/, and all of the files are in the same directory. I have a php file that wants to serve those files, in directory root/c/, and needs to determine the content-type as defined by the .htaccess file. Is there any way to do this? PHP version is 5.1.6. mime_content_type returns text/plain, and I'd rather not try to parse the .htaccess file manually. I can move the file if necessary.

  • Compile time error: cannot convert from specific type to a generic type

    - by Water Cooler v2
    I get a compile time error with the following relevant code snippet at the line that calls NotifyObservers in the if construct. public class ExternalSystem<TEmployee, TEventArgs> : ISubject<TEventArgs> where TEmployee : Employee where TEventArgs : EmployeeEventArgs { protected List<IObserver<TEventArgs>> _observers = null; protected List<TEmployee> _employees = null; public virtual void AddNewEmployee(TEmployee employee) { if (_employees.Contains(employee) == false) { _employees.Add(employee); string message = FormatMessage("New {0} hired.", employee); if (employee is Executive) NotifyObservers(new ExecutiveEventArgs { e = employee, msg = message }); else if (employee is BuildingSecurity) NotifyObservers(new BuildingSecurityEventArgs { e = employee, msg = message }); } } public void NotifyObservers(TEventArgs args) { foreach (IObserver<TEventArgs> observer in _observers) observer.EmployeeEventHandler(this, args); } } The error I receive is: The best overloaded method match for 'ExternalSystem.NotifyObservers(TEventArgs)' has some invalid arguments. Cannot convert from 'ExecutiveEventArgs' to 'TEventArgs'. I am compiling this in C# 3.0 using Visual Studio 2008 Express Edition.

  • Is testing every Anti-Virus definition before deployment feasible?

    - by Sim
    With the recent problems that McAfee customers have had over the last week there has been lots of opinion that not only should the AV vendors have better testing but customers should test AV signatures before deploying. Is this feasible? If you are doing this already do you take other measures to minimise exposure to malware while you are testing?

  • Clojure warn-on-reflection and type hints

    - by Ralph
    In the following code, I am getting a warning on reflection: (ns com.example (:import [org.apache.commons.cli CommandLine Option Options PosixParser])) (def *help-option* "help") (def *host-option* "db-host") (def *options* (doto (Options.) (.addOption "?" *help-option* false "Show this usage information") (.addOption "h" *host-option* true "Name of the database host"))) (let [^CommandLine command-line (.. (PosixParser.) (parse *options* (into-array String args))) db-host (.getOptionValue command-line "h")] ; WARNING HERE ON .getOptionValue ; Do stuff with db-host ) I have a type hint on command-line. Why the warning? I am using Clojure 1.2 on OS X 10.6.6 (Apple VM). I assume that I do not get a warning on (.addOption ...) because the compiler knows that (Options.) is a org.apache.commons.cli.Options).

  • Return an opaque object to the caller without violating type-safety

    - by JS Bangs
    I have a method which should return a snapshot of the current state, and another method which restores that state. public class MachineModel { public Snapshot CurrentSnapshot { get; } public void RestoreSnapshot (Snapshot saved) { /* etc */ }; } The state Snapshot class should be completely opaque to the caller--no visible methods or properties--but its properties have to be visible within the MachineModel class. I could obviously do this by downcasting, i.e. have CurrentSnapshot return an object, and have RestoreSnapshot accept an object argument which it casts back to a Snapshot. But forced casting like that makes me feel dirty. What's the best alternate design that allows me to be both type-safe and opaque?

  • which type is best for three radiobuttons?

    - by Manog
    Maybe you consider this question trivial but im just curious what is your opinion. I have three radiobuttons. "Show blue", "Show red" and "Show all". I did it with nullable boolean. There is collumn in database where blue is 0 and red is 1 so in metode i have to translate bool to int to compare those values (i do it in c#).Of course it works, but i wonder if it is the best solution. And question is wich type is best in this case? nullable bool, int, or maybe string?

  • Switch Case on type of object (C#)

    - by Sem Dendoncker
    If you want to switch a type of object, what is the best way to do this? ex: private int GetNodeType(NodeDTO node) { switch (node.GetType()) { case typeof(CasusNodeDTO): return 1; case typeof(BucketNodeDTO): return 3; case typeof(BranchNodeDTO): return 0; case typeof(LeafNodeDTO): return 2; default: return -1; } } I know this doesn't work that way, but I was wondering how you could solve this. Is an if then else else else statement appropriate in this case? Or do you use this switch and add .ToString() to the types? Kind regards, Sem

  • Implicit type conversion in DB/2 inserts?

    - by IronGoofy
    We're using SQL Inserts to insert some data via a script into DB/2 tables, e.g. CREATE TABLE TICKETS (TICKETID VARCHAR(10) NOT NULL); On my home installation, this statement works fine (note that I'm using an integer which is autoatically cast into a VarChar): INSERT INTO TICKETS (TICKETID) VALUES (1); while at my customer's site I get a type error. My question(s): Is this behavior version dependent? (I use a DB2 Express V9.7, while the customer has an Enterprise V9.5) Is there a config option to change the behavior? (I would like my home install to behave as close as possible as the production environment is going to be.)
