  • Simple ViewController / View, remove white bar?

    - by fuzzygoat
    I am just looking at setting up a simple viewController programatically, I have a ViewController.xib file that I have set the background color to RED in interface builder. I have also added the following to my AppDelegate.m @implementation syntax_MapViewAppDelegate @synthesize window; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { viewController = [[MapViewController alloc] init]; [window addSubview:[viewController view]]; [window makeKeyAndVisible]; return YES; } -(void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end When I run the code it does what I expect apart from the white bar at the bottom of the screen, can anyone give me any pointers in how to remove this? I have a feeling I might need to position the view within the window, but I am not sure how? cheers Gary

  • Has anyone managed to get jdotnetservices working on Android ?

    - by Bert
    I am trying to use jdotnetservices (http://www.jdotnetservices.com/), which is a java SDK for Windows Azure AppFabric, in an Android application. I have had to make some tweaks but only minor ones because jdotnetservices is written to target Java 1.6 and Android uses 1.5. I can get it to compile and run OK but I'm getting errors when I try to access the service bus ACS. Specifically, if I try to get a token from the service bus ACS I get this : Hostname mysolution-sb.accesscontrol.windows.net was not verified. Can anyone give me some pointers as to why this might be ? I can browse to the url of the ACS from Android : https://mysolution-sb.accesscontrol.windows.net/wrapv0.9 which gives me a certificate error, could this be why ? Any way round this ?

  • Apache modules: C module vs mod_wsgi python module - Performance

    - by Gopal
    Hi A client of ours is asking us to implement a module in C in Apache webserver for performance reasons. This module should handle RESTful uri's, access a database and return results in json format. Many people here have recommended python mod_wsgi instead - but for simplicity of programming reasons. Can anyone tell me if there is a significant difference in performance between the mod_wsgi python solution vs. the Apache + C.module. Any anecdotes? Pointers to some study posted online?

  • open encrypted file with php

    - by stormdrain
    Hi, I'm looking for a way to open encrypted files that are stored on a server. I'm using mcrypt to encrypt the files. I was initially going to create a class that would open the file, decrypt it, write it to a new location, then open that. But I have convinced myself there is a better way (I just don't know what it is). It seems like there should be a way to stream it (?) to the browser once it's decrypted. The initial setup would just link to the file location and the browser would take over (e.g. .pdf files would bring up a dialogue offering to open or save the file). If possible, I'd like it to do the same after decoding. Pointers? Advice? Bueller? Thanks!

  • Beginner's resources/introductions to classification algorithms.

    - by Dirk
    Hi, everybody. I am entirely new to the topic of classification algorithms, and need a few good pointers about where to start some "serious reading". I am right now in the process of finding out, whether machine learning and automated classification algorithms could be a worthwhile thing to add to some application of mine. I already scanned through "How to Solve It: Modern heuristics" by Z. Michalewicz and D. Fogel (in particular, the chapters about linear classifiers using neuronal networks), and on the practical side, I am currently looking through the WEKA toolkit source code. My next (planned) step would be to dive into the realm of Bayesian classification algorithms. Unfortunately, I am lacking a serious theoretical foundation in this area (let alone, having used it in any way as of yet), so any hints at where to look next would be appreciated; in particular, a good introduction of available classification algorithms would be helpful. Being more a craftsman and less a theoretician, the more practical, the better... Hints, anyone?

  • Custom User Management for Google App Engine Java

    - by Gopi
    I am using GAE Java for a multi-user application. There are multiple users with different roles. Each user can login, do some operations and logout. The business restricts me from using Google User Service and I need to implement my own for authentication and session management. Can anyone please share with me how should I go about implementing my own user management? I have read its very tricky to implement own user management. Any pointers in terms of best approaches/ design / existing frameworks if any ? I could see some similar posts but they are for python.

  • bad_application error starting erlang gen_server application

    - by user313475
    I have written a simple erlang app using gen_server. When starting it with application:start(myapp), I get the following tuple... {error,{bad_application,{application,myapp ... (rest of my application config). There are no other error or warning messages. I have also tried to google examples of how to configure gen_server and also the error itself. I am surprised at how little information there is out there. I could start trying to debug OTP?? Any pointers would be appreciated.

  • How to share a variable between two classes?

    - by Altefquatre
    How would you share the same object between two other objects? For instance, I'd like something in that flavor: class A { private string foo_; // It could be any other class/struct too (Vector3, Matrix...) public A (string shared) { this.foo_ = shared; } public void Bar() { this.foo_ = "changed"; } } ... // inside main string str = "test"; A a = new A(str); Console.WriteLine(str); // "test" a.Bar(); Console.WriteLine(str); // I get "test" instead of "changed"... :( I read there is some ref/out stuff, but I couldn't get what I'm asking here. I could only apply some changes in the methods scope where I was using ref/out arguments... I also read we could use pointers, but is there no other way to do it?

  • Recommended way to support backward/forward compatibility in iPhone app?

    - by MrAleGuy
    I'm in the early stages of an iPhone app and I have a question. I did some searching but did not find what I was looking for. There are features in iPhone OS4 that I would like to take advantage of, but I would like for my app to also run on 3.X. It looks like I want to develop against the 4.0 SDK and do the following: Create a "weak link" to any new (4.0) frameworks Call respondsToSelector: for any new method in an existing framework or any method in a new framework before making that call Am I close? What's recommended? Pointers to similar questions welcome.

  • maya "export all" window blocks my plugins script UI

    - by Hinchy
    I'm writing a custom File Translator for Maya which can export only (I have only declared the writer function). Currently having a problem with the MEL script which defines the plugin's options as a GUI. Currently I have a blank Maya scene, go to "file-export all". This creates the "File Export All" dialog, I then select my plugin exporter which runs my MEL script to create the bespoke options window. This new window is created behind the "File Export All" dialog and is not selectable! Do I have to place my export plugin specific options within the export all dialog rather than placing them in a separate window? Thanks for any links, tips or pointers you can provide.

  • Storing a reference to an object in C#

    - by Jack
    I was wondering how one could store a reference to an object in .net. That is, I would like something like the following code (note, of course, that the following code may be way off from how to actually do it): class Test { private /*reference to*/ Object a; public Test(ref int a) { this.a = a; this.a = ((int)this.a) + 1; } public Object getA() { return this.a; } } /* * ... */ static void Main(string[] args) { int a; a=3; Test t = new Test(ref a); Console.WriteLine(a); Console.WriteLine(t.getA()); Console.ReadKey(); } To produce the following output: 4 4 Ideally, I would like to do this without writing a wrapper class around the integer. In other words, I think I want pointers in .Net.

  • Injecting a response value into a textarea to subsequently post

    - by Ashbyrich
    I have multiple notes with class=.note and unique id each inside a div. On click of edit I grab the id, show hidden form #noteditor and hide all notes. I am using the load function to get the response (using codeigniter so url does work) and input result in the editorfrorm Textarea id = upnote... Firebug response looks ok and I have tried to inject into a div and this works fine, BUT getting this injto the text area is causing me some headaches. There is also the chance that i am going around this a convoluted way due to my limited knowledge... Any help or pointers v much appreciated... $(document).ready(function() { $('.edit').click(function(e){ var v=$(this).attr("id"); $(".note").slideUp(); $("#noteditor").slideDown('1000'); $("#upnote" ).load('/notes/my_note/'+v); e.preventDefault(); });

  • WebSphere MQ Low Latency Messaging - Does it have a JMS (or JMS like) API?

    - by Chris Kimpton
    We are currently using IBM MQ via JMS, but seem to be pushing through more messages than it can handle - strangely, the problem seems to be intermittent. The messages are prices and thus dont need to be guaranteed, just need to be sent quickly. As IBM have a Low Latency product, I am wondering if that is perhaps the better solution - but it does not seem to have a JMS api, or at least not easily visible. Anyone know if there is a JMS api into the Low Latency product, or if the "unique" API it does have is JMS-like... Alternatively, pointers for MQ tuning would also be appreciated... :)

  • starting 64 Bit Windows Application Development

    - by user173438
    I intend to start writing a 64 Bit Scientific Computing Application (signal processing) for Windows using Microsoft Visual Studio 2008. What should I have ready as far as a development platform is concerned? How would it be different from 32 Bit development? What could be the porting issues for a 32 Bit version that I already have (ok - this might too early to ask.. even before I start compiling)? As you might have guessed, I am looking for general directions. All pointers would be much appreciated! :) Thanks in advance..

  • Email notifications of exceptions happening in a Python app?

    - by ming yeow
    Hi folks, I want to set up email notifications when there is an error happening in my application. In ruby, there is a very elegant solution called ExceptionNotifier, which wraps around the exception handler and uses the built-in mailer to send an email. What is the best way of doing this in Python? I know that this is a very common issue, so would love for any tips that you folks can share! PS: Code samples, pointers to modules would be AWESOME! Thanks!

  • Which event handler to use to record leaving page - onunload or onbeforeunload?

    - by symcbean
    Hi all, Having not any answers to my previous questions about using javascript to measure page turn times, I'm going to start writing my own code (!). To measure the length of tie it takes, I'm proposing dropping a cookie containing a timestamp when the user browses away from a page, then in a subsequent page, comparing that time with 'now' and sending back a request to a URL which will log the interval. It seems that there are 2 possible handlers I could associate the first block of code with - the onunload() handler or the onbeforeunload()? It's more important that it fail silently on browsers with no/broken support for the handler, than it be portable across every possible browser. Any pointers? Gotchas? TIA C.

  • How to call memcmp() on two parts of byte[] (with offset)?

    - by brickner
    Hi, I want to compare parts of byte[] efficiently - so I understand memcmp() should be used. I know I can using PInvoke to call memcmp() - http://stackoverflow.com/questions/43289/comparing-two-byte-arrays-in-net But, I want to compare only parts of the byte[] - using offset, and there is no memcmp() with offset since it uses pointers. int CompareBuffers(byte[] buffer1, int offset1, byte[] buffer2, int offset2, int count) { // Somehow call memcmp(&buffer1+offset1, &buffer2+offset2, count) } Should I use C++/CLI to do that? Should I use PInvoke with IntPtr? How? Thank you.

  • Shell Script - comparing lines of text, deleting matches

    - by SirRatty
    Hi all, I've done some searching for this but cannot find what I'm after, specifically. I have two files: "a.txt", "b.txt". Each contains a list of email addresses, separated by newlines. For all lines in "a.txt", I need to check for a match anywhere in "b.txt". If so, the email address in "a.txt" needs to be removed. (Alternatively, a new file "c.txt" could be created with the output if that is easier.) I'm using Mac OS X, so am looking for a shell script that could help, or pointers to how I'd go about constructing the script. Thanks for any help.

  • Is there any self-improving compiler around?

    - by JohnIdol
    I am not aware of any self-improving compiler, but then again I am not much of a compiler-guy. Is there ANY self-improving compiler out there? Please note that I am talking about a compiler that improves itself - not a compiler that improves the code it compiles. Any pointers appreciated! Side-note: in case you're wondering why I am asking have a look at this post. Even if I agree with most of the arguments I am not too sure about the following: We have programs that can improve their code without human input now — they’re called compilers. ... hence my question.

  • How to open a pdf on the iPad from an AIR for iOS app

    - by Dennis Flood
    I am making an AIR for iOS app that can download pdfs. I do not want to display the pdf in the app itself but want the default pdf-viewer (iBooks) to launch and show the pdf. How can this be done. I am aware that navigateToURL can be used to open a file with the uri scheme of iBooks. But i dont know how to tell iBooks to look in the app-directory of my app. (Or is there some secret directory to place the file in from within the app - where iBooks can find it) Any pointers or help would be greatly appreciated as this is somewhat of a show stopper.

  • can QuickGraph support these requirements? (includes database persistence support)

    - by Greg
    Hi, Would QuickGraph be able to help me out with my requirements below? (a) want to model a graph of nodes and directional relationships between nodes - for example to model web pages/files linked under a URL, or modeling IT infrastructure and dependencies between hardware/software. The library would include methods such as * Node.GetDirectParents() //i.e. there could be more than one direct parent for a node * Node.GetRootParents() //i.e. traverse the tree to the top root parent(s) for the given node * Node.GetDirectChildren() * Node.GetAllChildren() (b) have to persist the data to a database - so it should support SQL Server and ideally SQLite as well. If it does support these requirement then I'd love to hear: any pointers to any parts of QuickGraph to dig into? what is the best concept re it's usage in terms of how to use database persistence - is it a simpler design to assume every search/method works directly on the database, or does QuickGraph support smarts to be able to work in memory and the "save" to database all changes at an appropriate point in time (e.g. like ADO.net does with DataTable etc) Thanks in advance

  • Silverlight Close/Cancel button

    - by Fizz
    This is for Silverlight 4, I want to create a new button class for a close/cancel button to use on dataentry screens. The aim is to move the "confirm cancel" interaction to the control rather than having it in the ViewModel. Functional outline: 1) Have a property IsDirty, needs to support binding 2) Has two "states", controled by IsDirty IsDirty = false - Content is "Close" IsDirty = true - Content is "Cancel" 3) When clicked if it is Dirty show a message box to confirm cancel, before calling the command 4) Both states will call the command Usage would be <i:CancelButton Command="{Binding Path=CloseCommand}" IsDirty="{Binding Path=IsDirty}"/> I am looking for pointers, I think a Templated Control would be the best option, but need some guidance on how to do this

  • Consuming WCF from BizTalk 2006r1

    - by Rob Bowman
    Hi I need to create an Orchestration in BizTalk 2006r1 that will consume a WCF basicHTTP web service. Does anyone have a pointers on how to do this please? The WCF service has been created by another team but I am able to request that they create an additional endpoint with binding configuration set to make calling from BizTalk SOAP adapter possible. I just created a simple test basicHTTP service that runs fine when tested from a command line client. When I got to BizTalk add web reference I am able to browse to the service but then get a message "Failed to add web reference" and it bombs out! Any help gratefully received. Thanks Rob.
