• MonoTouch- 'curated' bindings?

  - by Glinkot

  I'm just converting a video player sample to MT and came to this part: self.view.layer.sublayerTransform = CATransform3DMakePerspective(1000); In Monotouch, I've started with: this.View.Layer.SublayerTransform(CATransform3D.... But no perspective option is available. There is a 'scale' and 'rotate' one - does this mean this functionality is unavailable in MT? Or that I need to start creating my own bindings even though this one has been processed by the binding creation tool Xamarin uses? If anyone could advise how I would apply that transform I'd appreciate it. Cheers

• Unicode string handling using Windows API

  - by DeadMG

  I always assumed that Unicode string handling was some dark art. However, I've seen that the Windows API has functions for comparing Unicode strings, for example. Does that mean that it's actually feasible to write a Unicode string class that can perform simple actions like sorting, equality comparison, and extraction from a file? Or are there hidden gotchas in the use of these functions that makes it actually a really bad idea? I'm just looking at libraries like ICU and they seem incredibly over-complicated compared to what a Unicode string class backed by the Windows API could actually look like, which would resemble the Standard string classes quite closely.

• How to redirect a live data stream adding to it another header and returning it on demand? (PHP)

  - by Ole Jak

  I have a url like http://localhost:8020/stream.flv On request to my php sctipt I want to return (be something like a proxy) all data I can get from that URL (so I mean my php code should get data from that url and give it to user) and my header and my beginning of file. So I have my header and some data I want to write in the beginning of response like # content headers header("Content-Type: video/x-flv"); header("Content-Disposition: attachment; filename=\"" . $fileName . "\""); header("Content-Length: " . $fileSize); # FLV file format header if($seekPos != 0) { print('FLV'); print(pack('C', 1)); print(pack('C', 1)); print(pack('N', 9)); print(pack('N', 9)); } How to do such thing?

• Calling a WCF WebService in PHP via wsHttpBinding.

  - by Justin Dearing

  I have a WCF webservice I can connect to it via basicHttp, but not wsHttp. I try to conenct to it via wshttp via the following: $service = new SoapClient ("http://service.companyname.local:6666/Service/?wsdl", array( "location" => "http://service.companyname.local:6666/Service/WCF", "trace" => true, 'soap_version' => SOAP_1_2 ) ); The call to the SoapClient constructor returns fine. When I try to call one using $client-FunctionName, the page just sits there loading for quite a while, and eventually returns the error "Error Fetching http headers". What exactly is this supposed to mean and how do I fix it? (Consuming the service from .Net client works perfectly.)

• UITableView issue (iOS)

  - by Oktay

  I wonder why cellForRowAtIndexPath function is called when scrolling the UITableView. Does it mean on every scrolling cell configuration code runs again? I have a slowness problem when scrolling the table. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CountryCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... NSString *continent = [self tableView:tableView titleForHeaderInSection:indexPath.section]; NSString *country = [[self.countries valueForKey:continent] objectAtIndex:indexPath.row]; cell.textLabel.text = country; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; }

• Accessing 'data' argument of with() function?

  - by Ken Williams

  Is it possible, in the expr expression of the with() function, to access the data argument directly? Here's what I mean conceptually: > print(df) result qid f1 f2 f3 -1 1 0.0000 0.1253 0.0000 -1 1 0.0098 0.0000 0.0000 1 1 0.0000 0.0000 0.1941 -1 2 0.0000 0.2863 0.0948 1 2 0.0000 0.0000 0.0000 1 2 0.0000 0.7282 0.9087 > with(df, subset(.data, select=f1:f3)) # Doesn't work Of course the above example is kind of silly, but it would be handy for things like this: with(subset(df, f2>0), foo(qid, vars=subset(.data, select=f1:f3))) I tried to poke around with environment() and parent.frame() etc., but didn't come up with anything that worked. Maybe this is really a question about eval(), since that's how with.default() is implemented.

• Can ASP.NET be configured to run as an administrator when UAC is enabled?

  - by Steve Eisner

  I can't seem to find any information that indicates whether ASP.NET can be configured (through web.config or maybe machine.config) to run as a real administrator on a machine with UAC enabled. By this I mean, even if you set it to impersonate an Administrator account, UAC will disable that account's ability to act as an Administrator by returning a token set that hides the administrator role. For any checks such as IsInRole, the running account is effectively not an administrator at all. So ... Let's say I want to ignore all good advice and just go ahead and run a web app on Vista with administrator permissions. Is it even possible? Alternatives welcome. (Core reason for needing administrator privileges: to stop or start services that are running on that machine.)

• variable=@value@ in Makefiles

  - by user1447110

  I understand that @ suppresses printing of a command in a Makefile... http://www.gnu.org/software/make/manual/make.html#Echoing ... and I understand that $@ is the target name... http://www.gnu.org/software/make/manual/make.html#Automatic-Variables ... but I can't find any information on what a line like this might mean: variable=@value@ I'm not trying to fix anything here, just trying to better understand Makefiles. Update: The "Makefile Subsitutions" section of the GNU autoconf manual explains that it's a value that is substituted by autoconf.

• Is there any free, open source php CMS\framework for described case?

  - by Ole Jak

  I want that cms\framework to create me tables like "Users" "Cameras" and so on and declare classes and simple default methods for them (like paged sql relults and so on). I mean I say to it: I want Users to have ID, SpecialNumber and Name Flilds. and I want to get from it class for table generation (to call it once) and class containing methods such as Search by ID, SpecialNumber and Name, Create User, Delit User and so on functions. Is there any framework/cms like this for working with CODE not ui's and so on... so to say PHP generator or something... The result should be as that framework free as possible. So Is there any free, open source php CMS\framework for described case?

Thanks

• Can a real number "cover" all integers within its range?

  - by macias

  Is there a guarantee that a real number (float, double, etc) can "cover" all integers within its range? By cover I mean, that for every integer within its range there is such real number that this equality holds: real == int Or in another example, let's say I have the biggest real number which is smaller than given integer. When I add "epsilon" will I get this number equal to given integer or bigger than integer? (I know that among real numbers you should not write comparisons as == for equality, I am simply asking for better understanding subject, not for coding comparisons.)

• How to create GUI as inner class with WindowBuilder

  - by Tim Kemp

  I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

• How does Contract.Exists add value?

  - by Scott Bilas

  I am just starting to learn about the code contracts library that comes standard with VS2010. One thing I am running into right away is what some of the contract clauses really mean. For example, how are these two statements different? Contract.Requires(!mycollection.Any(a => a.ID == newID)); Contract.Requires(!Contract.Exists(mycollection, a => a.ID == newID)); In other words, what does Contract.Exists do in practical purposes, either for a developer using my function, or for the static code analysis system?

• Avoid stuck calling callback

  - by andlomba

  Hello all, This is a question about generic c++ event driven applications design. Lets assume that we have two threads, a "Dispatcher" (or "Engine"...) and a "Listener" (or "Client"...). Let's assume that I write the Dispatcher code, and release it as a library. I also write the Listener interface, of course. When the Dispatcher executes (after Listener registration) listenerInstance.onSomeEvent(); the event handling code will actually be executed by the Dispatcher thread, so if the person that implements the Listener writes something like void Listener::onSomeEvent() { while(true) ; } The Dispatcher will stuck forever. Is there a "plain old c++" (I mean no boost or libsigc++) way to "decouple" the two classes, so I can be sure that my Dispatcher will work fine whatever the Listeners does in the callbacks? bye and thanks in advance, Andrea

• What conditions cause a web browser to display the "Page Expired" message?

  - by RichardHowells

  I assumed that sending a page out with an expiry (a la)... Response.Cache.SetExpires(System.DateTime.Now.AddSeconds(5)); Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetValidUntilExpires(true); ...would mean that if the user hit the back button they would see the expired page. It does not seem to work that way. I found that using the back button would simply show the old (IMO expired) page. In fact in experimenting with different combinations of caching/not caching and expiry times I NEVER managed to get the "Page Expired" message out of the browser. What conditions provoke that message? Server Environment ASP .Net. I've only tested in IE8 - I'm assuming that other browsers are consistent here.

• Static dictionary in .Net Thread safety

  - by Emmanuel

  Reading msdn documentation for dictionaries it says : "Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." Those this mean that with a dictionary such as this : static object syncObject = new object(); static Dictionary<string,MyObject> mydictionary= new Dictionary<string, MyObject>(); Is doing something like the code below unnecessary? lock (syncObject) { context = new TDataContext(); mydictionary.Add("key", myObject); }

• C# What would happen to GC if I run process with priority = RealTime?

  - by Bobb

  I have a C# app which runs with priority RealTime. It was all fine until I made few hectic changes in past 2 days. Now it runs out of memory in few hours. I am trying to find whether it is a memory leak I created of this is because I consume lot more objects than before and GC simply cant collect them because it runs with same priority. My question is - what could happen to GC when it tries to collect objects in application with RealTime priority (there is also at least one thread running with Highest thread priority)? (P.S. by realtime priority I mean Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.RealTime)

• From where can i download free themes for my web application?

  - by Nitesh Panchal

  Hello, I am developing a web application and want to allow user to select theme for his/her personalization. I want to know from where can i find free css theme templates? By theme i mean, same css templates and it should have same css class names referenced in css file, because then only i can load the css file and the whole look and feel gets changed in webpage. If the class names in css files are different then it's not easy. Only thing that should change is images and background color etc. But the layout and css classes should remain same. Any help would be appreciated. Thanks in advance.

• How to use GPS data like the double value returned by getLatitude()?

  - by Dan

  I have been searching quite a bit for an answer, but maybe I'm just not using the correct terminology. I am creating an app that will access a database to return a list of other users that are within a certain distance of the users location. I've never worked with this type of data, and I don't really know what the values mean. I'd like to do all the calculations on the backend with either MySQL or PHP. Currently, I am storing the latitude and longitude as doubles within the database. I can access them and store them, but I have no idea how I might be able to sort them based on distance. Perhaps I should be using a different type or some technique that is common in this area. TIA.

• scala xml rewrite rule (or, simple pattern help)

  - by williamstw

  I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim

• SQL Server Operating System

  - by NDeveloper

  Hi, I found an interesting article about Platform layer for SQL Server. It talks about SQLOS. As I understand it is an abstraction layer between the hardware and SQL Server. So does it mean that we can have SQL Server installed without installing windows? It sounds very strange to me... Please tell me where it is possible to find more info on this. And also whoever have used SQLOS and for what reason? What are the main advantages from developers view?

• Using Java method to display HTML code

  - by javArc

  Hey folks, ok so this is my problem, I need to display HTML code in a jsp, which wouldn't be a problem, except a requirement for this project is that we place all the code in a public class file and have seperate methods for each chunk(header, sidebar footer, etc). Now here's where i'm confused: "Your method should take the PrintWriter as a parameter to print out each line of HTML, and should have a return type of void" What does that mean? How do I pass the PrintWriter into a method? Does this make sense to anyone?

• PrintingPermissionLevel, SafePrinting, and restrictions

  - by Steve Cooper

  There is a PrintingPermission attribute in the framework which takes a PrintingPermissionLevel enumeration with one of these values; NoPrinting: Prevents access to printers. NoPrinting is a subset of SafePrinting. SafePrinting: Provides printing only from a restricted dialog box. SafePrinting is a subset of DefaultPrinting. DefaultPrinting: Provides printing programmatically to the default printer, along with safe printing through semirestricted dialog box. DefaultPrinting is a subset of AllPrinting. AllPrinting: Provides full access to all printers. The documentation is really sparse, and I wondered if anyone can tell me more about the SafePrinting option. What does the documentation mean when it says "Provides printing only from a restricted dialog box." I have no idea what this means. Can anyone shed any light? This subject is touched in the MS certification 70-505: TS: Microsoft .NET Framework 3.5, Windows Forms Application Development and so I'm keen to find out more.

• Is there any way I can use two monitors in the console in Linux?

  - by Alex

  I have recently become the proud owner of two monitors in my workspace. (Ok not owner, but you know what I mean) and I'd like to use both of them at once. Problem is, I much much prefer to use a Linux Server console over a desktop environment. The graphics card on the machine is a GTX295 (don't ask why, it's a long story.) so I essentially have two graphics cards. Each has a DVI output. Is there any way I can get the console to stretch across two screens? Or will I have to install a desktop Ubuntu for this to work?
