  • Cannot run file_get_contents() on PHP 5.2.9-2

    - by Obay
    Hello, I am having the same problem as described below. http://marc.info/?l=php-general&m=124104032703506 The guy answered his own question by: "Sorry, didn't pay attention to the registered streams :-( You need to install a PHP package with ssl or compile it with --with-openssl." What does that mean? I'm fairly new to all this stuff and I don't quite understand what he was talking about, (e.g. registered streams, ssl). We have another server that has SSL. Does he mean that if I just transfer to that server, problem solved? Or is there anything else I need to consider? Can you please help me out? Any help is much appreciated :)

  • (C#) graphics.drawImage has a size limit? How to deal with it?

    - by DGH
    I am attempting to display a very large graphical representation of some data. I am using a bitmap for persistent storage of the image and e.Graphics.DrawImage(myBitmap, new Point(0,0)) in the onPaint of a PictureBox control on my form. I have noticed (and heard mentioned on other sites) that if my image has a height or width greater than 2^15, I get a Parameter not Valid exception, but I have not found any official documentation of this limit. Is this 2^15 image size limit a definite, official part of Graphics.DrawImage? Are there any simple workarounds to render my entire image onto the form? (Yes, the pictureBox is set to the same size as the image, or bigger. Side question though, should I just be using the onPaint of the form itself instead of a picture box?)

  • Identifying NHibernate proxy classes

    - by Marc Gravell
    I'm not an NHibernate user; I write a serialization utility library. A user has logged a feature-request that I should handle NHibernate proxy classes, treating them the same as the actual type. At the moment my code is treating them as unexpected inheritance, and throwing an exception. The code won't know in advance about NHibernate (including no reference, but I'm not aftaid of reflection ;-p) Is there a robust / guaranteed way of detecting such proxy types? Apparently DataContractSerializer handles this fine, so I'm hoping it is something pretty simple. Perhaps some interface or [attribute] decoration. Also, during deserialization; at the moment I would be creating the original type (not the NHibernate type). Is this fine for persistence purposes? Or is the proxy type required? If the latter; what is required to create an instance of the proxy type?

  • Convert a generic list to an array

    - by Freewind
    I have searched for this, but unfortunately, I don't get the correct answer. class Helper { public static <T> T[] toArray(List<T> list) { T[] array = (T[]) new Object[list.size()]; for (int i = 0; i < list.size(); i++) { array[i] = list.get(i); } return array; } } Test it: public static void main(String[] args) { List<String> list = new ArrayList<String>(); list.add("abc"); String[] array = toArray(list); System.out.println(array); } But there is an error thrown: Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.String; at test.Helper.main(Helper.java:30) How to solve this?

  • Program skips code after trying to parse XML in VB.NET

    - by Bead
    I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

  • Problems finding classes in namespace

    - by Matt
    I am trying to find all of the types in the Models namespace within an ASP.NET MVC assembly from within a testing assembly. I was trying to use LINQ to find the relevant set for me but it is returning an empty set on me. I am sure it is some simple mistake, I am still relatively new to LINQ admittedly. var abstractViewModelType = typeof (AbstractViewModel); var baseAssembly = Assembly.GetAssembly(abstractViewModelType); var modelTypes = baseAssembly.GetTypes() .Where(assemblyType => (assemblyType.Namespace.EndsWith("Models") && assemblyType.Name != "AbstractViewModel")) .Select(assemblyType => assemblyType); foreach(var modelType in modelTypes) { //Assert some things } When I reach the foreach I receive a Null reference exception.

  • Strange Scala error.

    - by Lukasz Lew
    I tried to create abstract turn based Game and abstract AI: abstract class AGame { type Player type Move // Player inside def actPlayer : Player def moves (player : Player) : Iterator[Move] def play (move : Move) def undo () def isFinished : Boolean def result (player : Player) : Double } abstract class Ai[Game <: AGame] { def genMove (player : Game#Player) : Game#Move } class DummyGame extends AGame { type Player = Unit type Move = Unit def moves (player : Player) = new Iterator[Move] { def hasNext = false def next = throw new Exception ("asd") } def actPlayer = () def play (move : Move) { } def undo () { } def isFinished = true def result (player : Player) = 0 } class DummyAi[Game <: AGame] (game : Game) extends Ai[Game] { override def genMove (player : Game#Player) : Game#Move = { game.moves (player).next } } I thought that I have to use this strange type accessors like Game#Player. I get very puzzling error. I would like to understand it: [error] /home/lew/Devel/CGSearch/src/main/scala/Main.scala:41: type mismatch; [error] found : Game#Player [error] required: DummyAi.this.game.Player [error] game.moves (player).next [error] ^

  • Eclipse RCP & tycho - The type org.eclipse.swt.widgets.Button cannot be resolved. It is indirectly referenced from required .class files

    - by Skip
    Situation: I have an Eclipse RCP Application, which I am trying to build with tycho plugin for Eclipse. When I am executing my Eclipse Application inside of the IDe - the Application is executed normally. When using tycho to build the Application - the following error is thrown: The type org.eclipse.swt.widgets.Button cannot be resolved. It is indirectly referenced from required .class files What I did : In other cases where a "missing requirenments" exception was thrown, which I found - a missing transitive plugin-dependency was the reason. In my case an SWT widget "Button" is missing, so I am trying to import swt. SWT is platform dependant so I am importing swt inside of the product, as described here. Anyway, during compilation the error occurs again. Question: Do someone have any Idea, how to solve this Problem?

  • Calling a function of en external javascript file

    - by strakastroukas
    Hello. In general... How can I make a call on a function of an external javascript file? More specific... In the head tag i have <script type="text/javascript" src="JScript/FontSize.js"></script> The external javascript file, (that i would like to call) FontSize.js contains the following functions. function checkCookie() function setCookie(c_name, value, expiredays) function getCookie(c_name) function increaseFontSize() function decreaseFontSize() The FontSize.js is located at the ~/Jscript/ directory I guess the body on load should contain something like <body onload="/JScript/Fontsize.js/checkCookie()"> Of course nothing works as it should because, i do not know how to make the call to a function to an external js file

  • cakephp - try/catch an Action

    - by joshs
    I would like to somehow apply a try catch statement to all Actions as a backstop for any uncaught exceptions. I think this would be particularly helpful for Ajax Actions, because the catch statement could send back a default 4xx status code. Prototype's onFailure() function could then do the client-side error handling. How can I do this without wrapping the Action call with a try/catch in the cake dispatcher like this: try { output = $controller->dispatchMethod($params['action'], $params['pass']); } catch {...} Does anybody have a suggestion or another workable strategy for gaining this functionality without touching the dispatcher? How do people feel about putting exception handling in the Displatcher? I imagine when cake drops php 4 support, there will be a built-in mechanism for this.

  • Windows Mobile Development on MacBook Pro?

    - by Ted Nichols
    I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

  • Is there a DRMAA Java library that works with Torque/PBS?

    - by dondondon
    Does anybody know a Java implementation of the DRMAA-API that is known to work with PBS/Torque cluster software? The background behind this: I would like to submit jobs to a newly set-up linux cluster from java using a DRMAA compliant API. The cluster is managed by PBS/Torque. Torque includes PBS DRMAA 1.0 library for Torque/PBS that contains a DRMA-C binding and provides in libdrmaa.so and .a binaries. I know that Sun grid engine includes a drmaa.jar providing a Java-DRMAA API. In fact I opted to use SGE but it was decided to try PBS first. The theory behind that decision was: 'DRMAA is a standard and therefore a Java API needs only a standards compliant drmaa-c binding.' However, I couldn't find such 'general DRMAA-C-java API' and now assume that this assumption is wrong and that the Java libraries are engine specific. Are we stuck here? Any comments appreciated.

  • How to handle request-wise DB transactions in ASP.NET MVC?

    - by Dario Solera
    I'm using SubSonic 3.0 (SimpleRepository) to handle database access in my ASP.NET MVC 1.0 application. It would be nice to handle a transaction for every web request, committing if everything went smooth and rolling back in case of exception. Is this possible? If so, how? I know this topic has been discussed many times, but I just couldn't find a satisfactory answer. I have built my own solution (create a TransactionScope in the controller, then commit/rollback in OnActionExecuted), but it turns out to be very unreliable.

  • creating a Menu from SQLite values in Java

    - by shanahobo86
    I am trying to create a ListMenu using data from an SQLite database to define the name of each MenuItem. So in a class called menu.java I have defined the array String classes [] = {}; which should hold each menu item name. In a DBAdapter class I created a function so the user can insert info to a table (This all works fine btw). public long insertContact(String name, String code, String location, String comments, int days, int start, int end, String type) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_NAME, name); initialValues.put(KEY_CODE, code); initialValues.put(KEY_LOCATION, location); initialValues.put(KEY_COMMENTS, comments); initialValues.put(KEY_DAYS, days); initialValues.put(KEY_START, start); initialValues.put(KEY_END, end); initialValues.put(KEY_TYPE, type); return db.insert(DATABASE_TABLE, null, initialValues); } It would be the Strings inserted into KEY_NAME that I need to populate that String array with. Does anyone know if this is possible? Thanks so much for the help guys. If I implement that function by Sam/Mango the program crashes, am I using it incorrectly or is the error due to the unknown size of the array? DBAdapter db = new DBAdapter(this); String classes [] = db.getClasses(); edit: I should mention that if I manually define the array: String classes [] = {"test1", "test2", "test3", etc}; It works fine. The error is a NullPointerException Here's the logcat (sorry about the formatting). I hadn't initialized with db = helper.getReadableDatabase(); in the getClasses() function but unfortunately it didn't fix the problem. 11-11 22:53:39.117: D/dalvikvm(17856): Late-enabling CheckJNI

  • [Java] - Problem having my main thread sleeping

    - by Chris
    I'm in a Java class and our assignment is to let us explore threads in Java. So far so good except for this one this one problem. And I believe that could be because of my lack of understanding how Java threads work at the moment. I have the main thread of execution which spawns new threads. In the main thread of execution in main() I am calling Thread.sleep(). When I do I get an Unhandled exception type InterruptedException. I am unsure of why I am getting this? I thought this was because I needed a reference to the main thread so I went ahead and made a reference to it via Thread.currentThread(). Is this not the way to have the thread sleep? What I need to do is have the main thread wait/sleep/delay till it does it required work again. Any help would be much appreciated.

  • Albacore msbuild task problem

    - by Dejan
    Just updated albacore to version 0.14 and ran into a major problem. My current environment is: Ruby 1.9.1 Rake 0.8.7 Albacore 0.1.4 The problem is that as of now all my rake build throw a funny little exception: undefined method 'push' for #<Enumerator:0x???????> So far I have traced the problem to albacore msbuild.rb line 38 and 26. To be honest I just don't have a clue why this is happening. As a little help here is the rake task that is turning my hear Grey :) desc "Build solution" msbuild :build => :prepareOutput do |msb| msb.properties :configuration => :Release msb.targets :Clean, :Build msb.solution = "../xxx/xxx/xxx.sln" end

  • Branchless memory manager?

    - by Richard Fabian
    Anyone thought about how to write a memory manager (in C++) that is completely branch free? I've written a pool, a stack, a queue, and a linked list (allocating from the pool), but I am wondering how plausible it is to write a branch free general memory manager. This is all to help make a really reusable framework for doing solid concurrent, in-order CPU, and cache friendly development. Edit: by branchless I mean without doing direct or indirect function calls, and without using ifs. I've been thinking that I can probably implement something that first changes the requested size to zero for false calls, but haven't really got much more than that. I feel that it's not impossible, but the other aspect of this exercise is then profiling it on said "unfriendly" processors to see if it's worth trying as hard as this to avoid branching.

  • Does JavaME and/or Proguard reorder assignments?

    - by chrisdew
    This is a simplified example - I have two threads: Can JavaME and/Proguard ever reorder the obX = ... statements, such that thread_B will have a null pointer exception at ob2.someMethod? thread_A: Object ob1 = null; Object ob2 = null; ... ob1 = something1; ob2 = something2; thread_B: if (ob2 != null) { ob1.someMethod(); ... } P.S. I do realise that synchronising these will avoid the issue. Synchronisation has both a performance overhead, and more importantly, a chance to introduce deadlock.

  • Allow single-line accessor (getter/setter) syntax with Checkstyle

    - by Sam3
    We'd like to have trivial Java property accessors using a single line syntax, so they take up much much less space, and are more readable (in terms of 'seeing' the set of accessors quickly). But we do want to enforce multi-line method syntax for everything else in our checkstyle configuration. But I'm not sure how to make this exception for accessors in Checkstyle config and suspect it may not be possible. So we'd like our accessors to look something like this: public String getFoo() { return foo; } public void setFoo(String foo) { this.foo = foo; } [In fact we'd rather not have trivial accessors at all and instead just annotate the private member variables with @Property or something and have the accessors generated for us, since writing endless get and set code delivers no real benefit, but that's a general Java frustration and an aside as far as this question goes.]

  • Reading data from a socket, considerations for robustness and security

    - by w.brian
    I am writing a socket server that will implement small portions of the HTTP and the WebSocket protocol, and I'm wondering what I need to take into consideration in order to make it robust/secure. This is my first time writing a socket-based application so please excuse me if any of my questions are particularly naive. Here goes: Is it wrong to assume that you've received an entire HTTP request (WebSocket request, etc) if you've read all data available from the socket? Likewise, is it wrong to assume you've only received one request? Is TCP responsible for making sure I'm getting the "message" all at once as sent by the client? Or do I have to manually detect the beginning and end of each "message" for whatever protocol I'm implementing? Regarding security: What, in general, should I be aware of? Are there any common pitfalls when implementing something like this? As always, any feedback is greatly appreciated.

  • Variable alpha blending in pylab

    - by Hooked
    How does one control the transparency over a 2D image in pylab? I'd like to give two sets of values (X,Y,Z,T) where X,Y are arrays of positions, Z is the color value, and T is the transparency to a function like imshow but it seems that the function only takes alpha as a scalar. As a concrete example, consider the code below that attempts to display two Gaussians. The closer the value is to zero, the more transparent I'd like the plot to be. from pylab import * side = linspace(-1,1,100) X,Y = meshgrid(side,side) extent = (-1,1,-1,1) Z1 = exp(-((X+.5)**2+Y**2)) Z2 = exp(-((X-.5)**2+(Y+.2)**2)) imshow(Z1, cmap=cm.hsv, alpha=.6, extent=extent) imshow(Z2, cmap=cm.hsv, alpha=.6, extent=extent) show() Note: I am not looking for a plot of Z1+Z2 (that would be trivial) but for a general way to specify the alpha blending across an image.

  • Prevent Visual Studio Web Test from changing request details

    - by keithwarren7
    I have a service that accepts Xmla queries for Analysis services, often times those queries themselves will have a string that contains a fragment that looks something like {{[Time].[Year].[All]}} Recording these requests works fine but when I try to re-run the test I get an error from the test runner... Request failed: Exception occurred: There is no context parameter with the name ' [Time].[Year].[All]' in the WebTestContext This was confusing for some time but when I asked VS to generate a coded version of the test I was able to see the problem a bit better. VS searches for the '{{' and '}}' tokens and makes changes, considering those areas to refer to Context parameters, the code looks like this.Context["\n\t[Time].[Year].[All]"].ToString() Anyone know how to instruct Visual Studio to not perform this replacement operation? Or another way around this issue?
