  • Find out why Xcode has decided to link to a particular library

    - by andygeers
    I'm using the Unity 3D engine to build an iPhone app, and when I go to generate my Xcode project for compilation, it includes a few fairly large libraries: Mono.Security.dll.s, System.dll.s, System.Core.dll.s, etc. I don't know if this question is really an Xcode question or a Unity question, but I'm trying to figure out why each of those libraries is being linked - which functions / classes are being referenced - ideally so that I can rewrite my code to remove as many of the dependencies as possible. Does anybody know a way to find this information out?

  • vim unicode bufread/bufwrite script

    - by anon
    Problem: I want my unicode characters to be stored on disk as (rather tan utf8/16 encoding) \u#### However, I want them dispalyed as unicode characters when opened up in vim. I think the easiest way to acheive this is some bufopen/bufwrite script that automatically: on opening, convert \u#### to unicode character on writing, convert unicode characters into \u#### However, I don't know what functions to call to make this happen. Can someone lend a hand? Thanks!

  • How to add Google Calendar Dynamically to jQuery FullCalendar?

    - by crosenblum
    I have seen how to add google calendar, but when I run it, it create's a new calendar, even though the selector I am using, refer's to an existing calendar. $calendar.fullCalendar({ events: $.fullCalendar.gcalFeed($feed_url.val()) }); I have other functions, that use renderEvents, but I am not sure how to use that with google calendars... Any thoughts or suggestions? Thank You.

  • Where to go from PHP?

    - by dabito
    I'm a seasoned PHP programmer and I really like the way it works and find it very fun to work with (performance could be improved and some functions renamed, but nothing too serious). However, I took a java seminar and now Im very interested in using GWT for upcomming projects, although I think the learning curve can be steep. Should I really go through with this change (PHP JAVA)? Where to begin?

  • Reopening serial port fails if not closed properly with CloseHandle

    - by superg
    I am working with USB device on Windows that is seen as a virtual serial port. I can communicate with the device using CreateFile and ReadFile functions, but in some cases my application does not call CloseHandle (when my application in development crashes). After that all calls to CreateFile fail (ERROR_ACCESS_DENIED), and the only solution is to log in to my computer again. Is there any way to force closing the open handle (or reopening) programmatically?

  • Determining when or when not to escape output

    - by Ygam
    I have a page, where I have approximately 90 items I need to output. Most of them are object properties (I am using ORM so these objects map to my database tables). But the question is, do I have to escape each of those 90 outputs by applying functions to each (in my case, the htmlspecialchars)? Wouldn't that add a bit of an overhead (calling a single function 90 times)?

  • Getting rid of "static" references in C#

    - by DevEight
    Hello. I've recently begun learning C# but have encountered an annoying problem. Every variable I want available to all functions in my program I have to put a "static" in front of and also every function. What I'd like to know is how to avoid this, if possible? Also, small side question: creating public variables inside functions? This is what my program looks like right now, and I want to basically keep it like that, without having to add "static" everywhere: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Threading; using System.Net.Sockets; namespace NetworkExercise { class Client { public IPAddress addr; public int port; public string name; public Thread thread; public TcpClient tcp; public NetworkStream stream; public Client(IPAddress addr, int port, string name, NetworkStream stream) { } } class Program { //NETWORK TcpListener tcpListener; Thread listenThread; ASCIIEncoding encoder = new ASCIIEncoding(); //DATA byte[] buffer = new byte[4096]; string servIp; int servPort; //CLIENT MANAGEMENT int clientNum; static void Main(string[] args) { beginConnect(); } public void beginConnect() { Console.Write("Server IP (leave blank if you're the host): "); servIp = Console.ReadLine(); Console.Write("Port: "); servPort = Console.Read(); tcpListener = new TcpListener(IPAddress.Any, servPort); listenThread = new Thread(new ThreadStart(listenForClients)); listenThread.Start(); } public void listenForClients() { tcpListener.Start(); Console.WriteLine("Listening for clients..."); while (true) { Client cl = new Client(null, servPort, null, null); cl.tcp = tcpListener.AcceptTcpClient(); ThreadStart pts = delegate { handleClientCom(cl); }; cl.thread = new Thread(pts); cl.thread.Start(); } } public void handleClientCom(Client cl) { cl.stream = cl.tcp.GetStream(); } } }

  • FileStream to save file then immediately unlock in .NET ?

    - by aron
    I have this code that saves a pdf file. FileStream fs = new FileStream(SaveLocation, FileMode.Create); fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length); fs.Flush(); fs.Close(); It works fine. However sometimes it does not release the lock right away and that causes file locking exceptions with functions run after this one run. Is there a ideal way to release the file lock right after the fs.Close()

  • Nested Execution Flow Control

    - by chris
    I've read tens of answers related to callbacks, promises and other ways to control flow, but I can't still wrap my head around this task, obviously due to my lack of competence. I have a nested problem: In test_1() (and the other functions) I would like to ensure that the rows are added to the table according to the order in which the elements are in the object; I would like to execute either test_2 or test_3 (or both after each other) only after test_1 has finished completely. Actually the right sequence will only be known at runtime (there will be a switch with the possible sequences, like 1,2,3 or 1,3,2 or 1,2,1,3 or 1,3,3,2, etc...) Code: $(function () { // create table tbl = document.createElement('table'); tbl.className = "mainTbl"; $("body").append(tbl); }); function test_1() { $.each(obj, function () { var img = new Image(); img.onload = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "loaded"; }; img.onerror = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "not loaded"; }; img.src = this.url; }); } function test_2() { $.each(obj, function () { var img = new Image(); img.onload = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "loaded"; }; img.onerror = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "not loaded"; }; img.src = this.url; }); } function test_3() { $.each(obj, function () { var img = new Image(); img.onload = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "loaded"; }; img.onerror = function () { // add row of data to table var row = tbl.insertRow(-1); var c1 = row.insertCell(0); c1.innerHTML = "not loaded"; }; img.src = this.url; }); } I know that calling the functions in sequence doesn't work as they don't wait for each other... I think promises are they way to go but I can't find the right combination and the documentation is way too complex for my skills. What's the best way to structure the code so that it's executed in the right order?

  • adding javascript events to freemind maps

    - by pri_dev
    I have created freemind maps using the tool, right now in the process of integrating the map with my web application. I have some questions on the usage of freemind maps 1) Instead of using the freemindbrowser.html and the jar file to integrate a map with a website/ web app, can we do an export to Javascript from the tool and then integrate that exported file (.html) with the web site? 2) I want to be able to add javascript functions on events like node click, how do I do that? Thanks in Advance

  • Validate input parameters in VB?

    - by EdOxH
    Should I validate input parameters on all functions I create? Input isn't passed from a user, but from other routines as part of an automatic process. I use error handling. I'm not sure what more validating input could do for me. If the input isn't valid, that's pretty much the same thing as an error, isn't it?

  • SQL Server error handling: exceptions and the database-client contract

    - by gbn
    We’re a team of SQL Servers database developers. Our clients are a mixed bag of C#/ASP.NET, C# and Java web services, Java/Unix services and some Excel. Our client developers only use stored procedures that we provide and we expect that (where sensible, of course) they treat them like web service methods. Some our client developers don’t like SQL exceptions. They understand them in their languages but they don’t appreciate that the SQL is limited in how we can communicate issues. I don’t just mean SQL errors, such as trying to insert “bob” into a int column. I also mean exceptions such as telling them that a reference value is wrong, or that data has already changed, or they can’t do this because his aggregate is not zero. They’d don’t really have any concrete alternatives: they’ve mentioned that we should output parameters, but we assume an exception means “processing stopped/rolled back. How do folks here handle the database-client contract? Either generally or where there is separation between the DB and client code monkeys. Edits: we use SQL Server 2005 TRY/CATCH exclusively we log all errors after the rollback to an exception table already we're concerned that some of our clients won't check output paramaters and assume everything is OK. We need errors flagged up for support to look at. everything is an exception... the clients are expected to do some message parsing to separate information vs errors. To separate our exceptions from DB engine and calling errors, they should use the error number (ours are all 50,000 of course)

  • iPhone: Create a single UIView from multiple clicks

    - by Cuzog
    I'm making a partial overlay modal in my app with the code from “Semi-Modal (Transparent) Dialogs on the iPhone” at ramin.firoozye.com. In doing so, the button that calls the modal is still visible and clickable. I will hide this button when the modal spawns, but I want to be sure if the user clicks very quickly twice, a new modal doesn't come up for each click. What is the best way to check that the modal doesn't already exist when calling it from the button click? You can download the test project here. For those that don't have xcode, the relevant functions are below: I call forth the modal on button click with this: - (IBAction)displayModal:(id)sender { ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; modalController.view.frame = CGRectOffset(modalController.view.frame, 0, 230); [self showModal:modalController.view]; } Then use this function to animate the custom modal over the current view: - (void)showModal:(UIView*) modalView { UIWindow* mainWindow = (((TestAppDelegate*) [UIApplication sharedApplication].delegate).window); CGPoint middleCenter = modalView.center; CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); modalView.center = offScreenCenter; // we start off-screen [mainWindow addSubview:modalView]; // Show it with a transition effect [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; // animation duration in seconds modalView.center = middleCenter; [UIView commitAnimations]; } Then I dismiss the modal on button click with this: - (IBAction)dismissModal:(id)sender { [self hideModal:self.view]; } And then use these functions to animate the modal offscreen and clean itself up: - (void)hideModal:(UIView*) modalView { CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); [UIView beginAnimations:nil context:modalView]; [UIView setAnimationDuration:0.7]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(hideModalEnded:finished:context:)]; modalView.center = offScreenCenter; [UIView commitAnimations]; } - (void)hideModalEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { UIView* modalView = (UIView *)context; [modalView removeFromSuperview]; [self release]; } Any help is greatly appreciated!

  • Dynamic memory managment under Linux

    - by petersohn
    I know that under Windows, there are API functions like global_alloc() and such, which allocate memory, and return a handle, then this handle can be locked and a pointer returned, then unlocked again. When unlocked, the system can move this piece of memory around when it runs low on space, optimising memory usage. My question is that is there something similar under Linux, and if not, how does Linux optimize its memory usage?

  • Drupal using Solr externally on another machine?

    - by Meg
    I'd like to use the Drupal solr search module with the Apache Solr Search hosted on an external machine. I know that Acquia offer this as a service. But it's not an affordable option for me. I'd like to install Solr on an inexpensive VPS and have all my various Drupal sites which are on different hosts accessing the search functions. Am I barking up the wrong tree?

  • How do I tell cmake to do these two steps to use winpcap?

    - by Gtker
    Quoted from here: If your program uses Win32 specific functions of WinPcap, remember to include WPCAP among the preprocessor definitions. If your program uses the remote capture capabilities of WinPcap, add HAVE_REMOTE among the preprocessor definitions. Do not include remote-ext.h directly in your source files. Has anyone managed to use winpcap with cmake?

  • CFPreferences for another (or all) users

    - by James Turner
    I'm working on a background service which needs to ask several users' iTunes settings (the users will opt-in via a helper application which they run from their login). Is there an easy way to read the preferences for another user, than the current one, using CFPreferences? The docs, for example for CFPreferencesCopyValue, explicitly state: 'Do not use arbitrary user and host names, instead pass the pre-defined domain qualifier constants.', when passing the 'userName' argument to the various functions.
