• OpenCL C/C++ dynamic binding library (win32 and more)

  - by rotoglup

  I'm giving a try at OpenCL, and in order to put this in production I'd like to be able to bind dynamically to OpenCL.DLL (when under Windows), in order to handle 'gracefully' the case where no OpenCL is installed on the host computer. Is there any available library (or code snippet) that takes care of this dynamic binding in C or C++, much like GLEW does for OpenGL ? I'd like to avoid the hassle to do it myself. Thanks,

• Is there a way to specify wildcarded region names when using ehcache with hibernate?

  - by bkent314

  When using Ehcache with Hibernate, is there a way to specify region names with wildcards in the ehcache.xml file? For example, to allow for cache settings at the package level (with * as a wildcard indicator): <cache name="com.example.my.package1.*" ... /> <cache name="com.example.my.package2.*" ... /> (Note: The package-level distinction is just an example. My question is to wildcards in the general case.)

• ideas: per-file authentication in order to download

  - by suIIIha

  i would love to use mod_xsendfile but i live in a shared environment which does not provide such a module. processing large files such as videos through a server-side script and sending it to the browser that way seems to be unacceptable in my case, so i am looking for a way to enable per-file authentication in such a way that is not going to consume resources much. nobody shall know what the actual path is to the file they are downloading. please suggest how to do that.

• Re-load Android activity data

  - by rhinds

  Hi, I am writing an Android app, part of which will be a survey involving multiple pages of checkbox question and answers. I have created an activity to display the question and options (from the DB) and what I want to do now is when i press the "Next" button it should just reload the current activity with the next question set from the database. (the activity starts with survey.getNextQuestion() - so its just a case of refreshing the activity so it updates) Im sure this is a simple thing to do -any ideas? Thanks

• How to refresh the properties view in Eclipse RCP?

  - by geejay

  I am using the properties view in RCP, i.e org.eclipse.ui.views.properties.PropertySheet. I want to be able to refresh the content of these properties programmatically. It seems RCP is geared towards the use case where this changes only when a selection changes. Is there any way I can fire a dummy event to get this to refresh (without having ugly UI artifacts such as visibly switching between parts) ?

• Android Assets No Value Read?

  - by BahaiResearch.com

  AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?

• How do I pass a multi-dimensional array as a GET parameter in PHP?

  - by Onema

  I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console...

• Controlling IFrame load time

  - by Venki

  Is there a way for me to control the load time of IFrames within my page. Consider the case where I have an HTML page, within which there are 2 IFrames being rendered. Is it possible to control the time it takes for the IFrames to load? In the sense, if the IFrame does not load within 10 secs, then I want to abort the loading of the iFrame.

• fire an intent from the onCreate method in android

  - by Sephy

  Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

• How to make PHP Curl request not to wait?

  - by understack

  I've a PHP function which fetches a Curl request. This request sometimes take longer time than expected and hence my php function takes longer to return. In my particular case, output of curl request is not important. So is it possible with curl just to place a request and proceed without waiting for curl_exec() to finish?

• SubSonic 3 LeftOuterJoin

  - by michaelpearce

  I have read in this forum that left outer join syntax is not supported by subsonic in an answer to a question on the topic by "Apocatastasis". I have the same issue in that when I create a query using the .LeftOuterJoin the resulting sql has an inner join rather than a left outer join. Can someone please confirm that LeftOuterJoin is indeed not supported and, if that is the case, why is it included in the active record syntax? Thanks Michael

• How to assign a value to an pointer-pointer passed in call by reference?

  - by mystify

  I want to achieve something similar to what these guys do here: - (NSUInteger)countForFetchRequest:(NSFetchRequest *)request error:(NSError **)error like you can see, you pass an NSError pointer and that nice method will assign a real NSError object to your pointer in case there is an error. So the cool thing about this is, that the method returns an NSUInteger but can ALSO return an NSError, without having to mess around with ugly and fat arrays or dictionaries. So how could I assign an object to the passed-in error pointer?

• Read -> change -> save. Thread safe.

  - by Pavel Alexeev

  This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.

• Class definition thinks setting a variable is a Unit?

  - by DeLongey

  Writing out a Scala class and problem here is that the compiler thinks that the code is a unit not returning the proper value. It's a method used to set a property in the class: def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } The error is: type mismatch; found : Unit required: com.stripe.StripeObject The full class is: case class EventData(var previousAttributes: HashMap[String,Object], var `object`:StripeObject) extends StripeObject { def getPreviousAttributes = { previousAttributes } def setPreviousAttributes(previousAttributes: HashMap[String, Object]) = { this.previousAttributes = previousAttributes } def getObject = { `object` } def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } } How do I make sure it doesn't return a Unit?

  Hi all, my app is an e-commerce application. During the checkout process, I have "recipient" and "credit card" screens. In the recipient screen, there are number of fields for address entry, which makes it very clumsy. Same in the case of the credit card screen, where the user is asked to enter their credit card info and billing address. Can anyone suggest how to design these two pages?
