  • NTLM Authentication fails when behind Proxy server

    - by Jan Petersen
    Hi All, I've seen a number of post about consuming Web Services from behind a proxy server, but none that seams to address this problem. I'm building a desktop application, using Java, JAX-WS in NetBeans. I have a working prototype, that can query the server for authentication mode, successfully authenticate and retrieve a list of web site. However, if I run the same app from a network that is behind a proxy server (the proxy does not require authentication), then I'm running into trouble. I have sniffed the traffic, and noticed the following: Behind Proxy # Result Protocol Host URL 1 200 HTTP host.domain.com /_vti_bin/Authentication.asmx 2 401 HTTP host.domain.com /_vti_bin/Webs.asmx 3 401 HTTP host.domain.com /_vti_bin/Webs.asmx 4 401 HTTP host.domain.com /_vti_bin/Webs.asmx 5 401 HTTP host.domain.com /_vti_bin/Webs.asmx Without Proxy # Result Protocol Host URL 1 200 HTTP host.domain.com /_vti_bin/Authentication.asmx 2 401 HTTP host.domain.com /_vti_bin/Webs.asmx 3 401 HTTP host.domain.com /_vti_bin/Webs.asmx 4 401 HTTP host.domain.com /_vti_bin/Webs.asmx 5 401 HTTP host.domain.com /_vti_bin/Webs.asmx 6 200 HTTP host.domain.com /_vti_bin/Webs.asmx When running the code from a network without a proxy server, I successfully Authentication with the server, but when I'm behind the proxy server, the traffic is cut-off at the 5th message, and thus don't succeed. I know from the Java docs that On Microsoft Windows platforms, NTLM authentication attempts to acquire the user credentials from the system without prompting the user's authenticator object. If these credentials are not accepted by the server then the user's authenticator will be called. Given that my Authentication code is called only ones, and only as the 5th attempt, it appears as if the connection is dropped when behind the proxy server before my Authentication object is used. Is there any way I can control the behavior of Authentication module, to not have it use the system credentials? I have put the source text java class files of a demo app up, showing the issue at the following urls (it's a bit to long even in the short demo form to post here). link text Br Jan

  • Why is Lua considered a game language?

    - by Hoffmann
    I have been learning about Lua in the past month and I'm absolutely in love with the language, but all I see around that is built with lua are games. I mean, the syntax is very simple, there is no fuss, no special meaning characters that makes code look like regex, has all the good things about a script language and integrates so painlessly with other languages like C, Java, etc. The only down-side I saw so far is the prototype based object orientation that some people do not like (or lack of OO built-in). I do not see how ruby or python are better, surely not in performance ( http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=lua&lang2=python ). I was planning on writting a web app using lua with the Kepler framework and Javascript, but the lack of other projects that use lua as a web language makes me feel a bit uneasy since this is my first try with web development. Lua is considered a kids language, most of you on stackoverflow probably only know the language because of the WoW addons. I can't really see why that is... http://lua-users.org/wiki/LuaVersusPython this link provides some insights on Lua against Python, but this is clearly biased.

  • searching for a programming platform with hot code swap

    - by Andreas
    I'm currently brainstorming over the idea how to upgrade a program while it is running. (Not while debugging, a "production" system.) But one thing that is required for it, is to actually submit the changed source code or compiled byte code into the running process. Pseudo Code var method = typeof(MyClass).GetMethod("Method1"); var content = //get it from a database (bytecode or source code) SELECT content FROM methods WHERE id=? AND version=? method.SetContent(content); At first, I want to achieve the system to work without the complexity of object-orientation. That leads to the following requirements: change source code or byte code of function drop functions add new functions change the signature of a function With .NET (and others) I could inject a class via an IoC and could thus change the source code. But the loading would be cumbersome, because everything has to be in an Assembly or created via Emit. Maybe with Java this would be easier? The whole ClassLoader is replacable, I think. With JavaScript I could achieve many of the goals. Simply eval a new function (MyMethod_V25) and assign it to MyClass.prototype.MyMethod. I think one can also drop functions somehow with "del" Which general-purpose platform can handle such things?

  • Finding usage of jQuery UI in a big ugly codebase

    - by Daniel Magliola
    I've recently inherited the maintenance of a big, ugly codebase for a production website. Poke your eyes out ugly. And though it's big, it's mostly PHP code, it doesn't have much JS, besides a few "ajaxy" things in the UI. Our main current problem is that the site is just too heavy. Homepage weighs in at 1.6 Mb currently, so I'm trying to clean some stuff out. One of the main wasters is that every single page includes the jQuery UI library, but I don't think it's used at all. It's definitely not being used in the homepage and in most pages, so I want to only include the where necessary. I'm not really experienced with jQuery, i'm more of a Prototype guy, so I'm wondering. Is there anything I could search for that'd let me know where jQuery UI is being used? What i'm looking for is "common strings", component names, etc For example, if this was scriptaculous, i'd look for things like "Draggable", "Effect", etc. Any suggestions for jQuery UI? (Of course, if you can think of a more robust way of removing the tag from pages that don't use it without breaking everything, I'd love to hear about it) Thanks!! Daniel

  • Better way to call superclass method in ExtJS

    - by Rene Saarsoo
    All the ExtJS documentation and examples I have read suggest calling superclass methods like this: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here... MyApp.MyPanel.superclass.initComponent.call(this); } }); I have been using this pattern for quite some time and the main problem is, that when you rename your class then you also have to change all the calls to superclass methods. That's quite inconvenient, often I will forget and then I have to track down strange errors. But reading the source of Ext.extend() I discovered, that instead I could use the superclass() or super() methods that Ext.extend() adds to the prototype: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here... this.superclass().initComponent.call(this); } }); In this code renaming MyPanel to something else is simple - I just have to change the one line. But I have doubts... I haven't seen this documented anywhere and the old wisdom says, I shouldn't rely on undocumented behaviour. I didn't found a single use of these superclass() and supr() methods in ExtJS source code. Why create them when you aren't going to use them? Maybe these methods were used in some older version of ExtJS but are deprecated now? But it seems such a useful feature, why would you deprecate it? So, should I use these methods or not?

  • UICollectionView with one static cell and N dynamic ones from a fetchresultscontroller exception

    - by nflacco
    I'm trying to make a UITableView that shows a blog post and comments for that post. My setup is a tableview in storyboard with two dynamic prototype cells. The first cell is for the post and should never change. The second cell represents the 0 to N comments. My cellForRowAtIndexPath method shows the post cell properly, but fails to get the comment at the given index path (though if I comment out the fetch I get the appropriate number of comment cells with a green background that I set as a visual debug thing). let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment I get the following exception on this line: 2014-08-24 15:06:40.712 MessagePosting[21767:3266409] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x0000000101aa43e5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001037f9967 objc_exception_throw + 45 2 CoreFoundation 0x000000010198f4c3 -[__NSArrayM objectAtIndex:] + 227 3 CoreData 0x00000001016e4792 -[NSFetchedResultsController objectAtIndexPath:] + 162 Section and cell setup: override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete method implementation. // Return the number of rows in the section. switch section { case 0: return 1 default: if let realPost:Post = post { return fetchedResultController.sections[0].numberOfObjects } else { return 0 } } } override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { switch indexPath.section { case 0: let cell = tableView.dequeueReusableCellWithIdentifier(postViewCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = lightGrey if let realPost:Post = self.post { cell.textLabel.text = realPost.text } return cell default: let cell = tableView.dequeueReusableCellWithIdentifier(commentCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = UIColor.greenColor() let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment // <---------------------------- :( cell.textLabel.text = comment.text return cell } } FRC: func controllerDidChangeContent(controller: NSFetchedResultsController!) { tableView.reloadData() } func getFetchedResultController() -> NSFetchedResultsController { fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: nil, cacheName: nil) return fetchedResultController } func taskFetchRequest() -> NSFetchRequest { if let realPost:Post = self.post { let fetchRequest = NSFetchRequest(entityName: "Comment") let sortDescriptor = NSSortDescriptor(key: "date", ascending: false) fetchRequest.predicate = NSPredicate(format: "post = %@", realPost) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } else { return NSFetchRequest(entityName: "") } }

  • Vertical crosshair reposition on Google Map after map resize Issue

    - by joe
    I use the following function to add a crosshair to my Google Map. It works great for horizontal resizing. I can not figure out how to make it work for vertical. After resizing the map it requires the user to either zoom in or out 1 layer, upon which the crosshair snaps to center. var crosshairsSize=17; GMap2.prototype.addCrosshairs=function(){ var container=this.getContainer(); if(this.crosshairs){$(this.crosshairs).remove();} var crosshairs=document.createElement("img"); crosshairs.src='../images/crosshair2.gif'; crosshairs.style.width=crosshairsSize+'px'; crosshairs.style.height=crosshairsSize+'px'; crosshairs.style.border='0'; crosshairs.style.position='relative'; crosshairs.style.top=((parseInt(container.clientHeight)-crosshairsSize)/2)+'px'; crosshairs.style.left="0px"; // The map is centered so 0 will do crosshairs.style.zIndex='500'; container.appendChild(crosshairs); this.crosshairs=crosshairs; return crosshairs;}; I use map.checkResize(); and the map is correct, it's just the crosshair that is off. I've tried firing a javascript zoom in one level but it doesn't work like zooming in with the mouse. It's only zooming in/out with the mouse scroll wheel too... clicking and dragging the zoom slider doesn't work so somehow it's liking the mouse scroll wheel. Firing addCrosshairs(); after resize makes no difference. It places the new crosshair in old spot and still requires a mouse scroll zoom.

  • How do I tell gcc to relax its restrictions on typecasting when calling a C function from C++?

    - by Daryl Spitzer
    I'm trying to use Cmockery to mock C functions called from C++ code. Because the SUT is in C++, my tests need to be in C++. When I use the Cmockery expect_string() macro like this: expect_string(mock_function, url, "Foo"); I get: my_tests.cpp: In function ‘void test_some_stuff(void**)’: my_tests.cpp:72: error: invalid conversion from ‘void*’ to ‘const char*’ my_tests.cpp:72: error: initializing argument 5 of ‘void _expect_string(const char*, const char*, const char*, int, const char*, int)’ I see in cmockery.h that expect_string is defined: #define expect_string(function, parameter, string) \ expect_string_count(function, parameter, string, 1) #define expect_string_count(function, parameter, string, count) \ _expect_string(#function, #parameter, __FILE__, __LINE__, (void*)string, \ count) And here's the prototype for _expect_string (from cmockery.h): void _expect_string( const char* const function, const char* const parameter, const char* const file, const int line, const char* string, const int count); I believe the problem is that I'm compiling C code as C++, so the C++ compiler is objecting to (void*)string in the expect_string_count macro being passed as the const char* string parameter to the _expect_string() function. I've already used extern "C" around the cmockery.h include in my_tests.cpp like this: extern "C" { #include <cmockery.h> } ...in order to get around name-mangling problems. (See "How do I compile and link C++ code with compiled C code?") Is there a command-line option or some other means of telling g++ how to relax its restrictions on typecasting from my test's C++ code to the C function in cmockery.c? This is the command I'm currently using to build my_tests.cpp: g++ -m32 -I ../cmockery-0.1.2 -c my_tests.cpp -o $(obj_dir)/my_tests.o

  • 1k of Program Space, 64 bytes of RAM. Is assembly an absolute must?

    - by Earlz
    (If your lazy see bottom for TL;DR) Hello, I am planning to build a new (prototype) project dealing with physical computing. Basically, I have wires. These wires all need to have their voltage read at the same time. More than a few hundred microseconds difference between the readings of each wire will completely screw it up. The Arduino takes about 114 microseconds. So the most I could read is 2 or 3 wires before the latency would skew the accuracy of the readings. So my plan is to have an Arduino as the "master" of an array of ATTinys. The arduino is pretty cramped for space, but it's a massive playground compared to the tinys. An ATTiny13A has 1k of flash ROM(program space), 64 bytes of RAM, and 64 bytes of (not-durable and slow) EEPROM. (I'm choosing this for price as well as size) The ATTinys in my system will not do much. Basically, all they will do is wait for a signal from the Master, and then read the voltage of 1 or 2 wires and store it in RAM(or possibly EEPROM if it's that cramped). And then send it to the Master using only 1 wire for data.(no room for more than that!). So far then, all I should have to do is implement trivial voltage reading code (using built in ADC). But this communication bit I'm worried about. Do you think a communication protocol(using just 1 wire!) could even be implemented in such constraints? TL;DR: In less than 1k of program space and 64 bytes of RAM(and 64 bytes of EEPROM) do you think it is possible to implement a 1 wire communication protocol? Would I need to drop to assembly to make it fit? I know that currently my Arduino programs linking to the Wiring library are over 8k, so I'm a bit concerned.

  • tips for fixing bad coding/dev habits ?

    - by dfafa
    i want to become a better coder....so i have decided to sign up for computing science program...maybe a formal education can assist me. i started working on smaller projects to learn but currently i have really bad coding/dev habits which is hindering my productivity as the codebase increases.... i have highlighted them and perhaps someone could make suggestions (or redirect to resources) or a more efficient method. most stuff that i made in the past were web apps. i usually develop with putty + nano...i just love the minimalist feel i use winscp and develop directly on my private web server...too lazy to do it on localhost and upload it later. i dont use subversion control...which one do i need ? sometimes ctrl +z doesn't work well. when i run out of ideas for naming variable, i use swear words instead. i swear a lot when i get stuck....how to deal with anger issue ? my codes look ugly with comments everywhere. would rather use procedural coding finds "thinking" in OO difficult and time consuming i "write first think later". refactors code only if i am getting paid for it. dislikes configuring linux distro, Apache, MySQL, scaling, designing graphics and layouts. does not like writing tests likes working alone. does not like sharing codes. has an econ degree dislikes reading other people's code would rather write it on my own it seems my only true desire is to translate my ideas to a working prototype as fast as possible....it seems like i am very uninterested in the other details...could it be that i am not cut out to be a coder after all ? is going back to study comp sci a bad idea ?

  • Prevent Rails link_to_remote multiple submits w Javascript

    - by Chris
    In a Rails project I need to keep a link_to_remote from getting double-clicked. It looks like :before and :after are my only choices - they get prepended/appended to the onclick Ajax call, respectively. But if I try something like: :before => "self.stopObserving()" t,he Ajax is never run. If I try it for :after the Ajax is run but the link never stops observing. The solutions I've seen rely on creating a variable and blocking the whole form, but there are multiple link_to_remote rows on this page and it is valid to click more than one of them at a time - just not the same one twice. One variable per row declared outside of link_to_remote seems very kludgey... Instead of using Prototype I originally tried plain Javascript first for this proof of concept - but it fails too: <a href="#" onclick="self.onclick = function(){alert('foo');};"click</a just puts up an alert when clicked - the lambda here does nothing? This next one is more like the desired goal and should only alert the first time. But instead it alerts every time: <a href="#" onclick="alert('bar'); self.onclick = function(){return false;};"click</a All ideas appreciated!

  • Show progress during a long Ajax call

    - by kousen
    I have a simple web site (http://www.kousenit.com/twitterfollowervalue) that computes a quantity based on a person's Twitter followers. Since the Twitter API only returns followers 100 at a time, a complete process may involve lots of calls. At the moment, I have an Ajax call to a method that runs the Twitter loop. The method looks like (Groovy): def updateFollowers() { def slurper = new XmlSlurper() followers = [] def next = -1 while (next) { def url = "http://api.twitter.com/1/statuses/followers.xml?id=$id&cursor=$next" def response = slurper.parse(url) response.users.user.each { u -> followers << new TwitterUser(... process data ...) } next = response.next_cursor.toBigInteger() } return followers } This is invoked from a controller called renderTTFV.groovy. I call the controller via an Ajax call using the prototype library: On my web page, in the header section (JavaScript): function displayTTFV() { new Ajax.Updater('ttfv','renderTTFV.groovy', {}); } and there's a div in the body of the page that updates when the call is complete. Everything is working, but the updateFollowers method can take a fair amount of time. Is there some way I could return a progress value? For example, I'd like to update the web page on every iteration. I know ahead of time how many iterations there will be. I just can't figure out a way to update the page in the middle of that loop. Any suggestions would be appreciated.

  • Javascript Reference Outer Object From Inner Object

    - by Akidi
    Okay, I see a few references given for Java, but not javascript ( which hopefully you know is completely different ). So here's the code specific : function Sandbox() { var args = Array.prototype.slice.call(arguments) , callback = args.pop() , modules = (args[0] && typeof args[0] === 'string' ? args : args[0]) , i; if (!(this instanceof Sandbox)) { return new Sandbox(modules, callback); } if (!modules || modules[0] === '*') { modules = []; for (i in Sandbox.modules) { if (Sandbox.modules.hasOwnProperty(i)) { modules.push(i); } } } for (i = 0; i < modules.length; i++) { Sandbox.modules[modules[i]](this); } this.core = { 'exp': { 'classParser': function (name) { return (new RegExp("(^| )" + name + "( |$)")); }, 'getParser': /^(#|\.)?([\w\-]+)$/ }, 'typeOf': typeOf, 'hasOwnProperty': function (obj, prop) { return obj.hasOwnProperty(prop); }, 'forEach': function (arr, fn, scope) { scope = scope || config.win; for (var i = 0, j = arr.length; i < j; i++) { fn.call(scope, arr[i], i, arr); } } }; this.config = { 'win' : win, 'doc' : doc }; callback(this); } How do I access this.config.win from within this.core.forEach? Or is this not possible?

  • Moving inserted container element if possible

    - by doublep
    I'm trying to achieve the following optimization in my container library: when inserting an lvalue-referenced element, copy it to internal storage; but when inserting rvalue-referenced element, move it if supported. The optimization is supposed to be useful e.g. if contained element type is something like std::vector, where moving if possible would give substantial speedup. However, so far I was unable to devise any working scheme for this. My container is quite complicated, so I can't just duplicate insert() code several times: it is large. I want to keep all "real" code in some inner helper, say do_insert() (may be templated) and various insert()-like functions would just call that with different arguments. My best bet code for this (a prototype, of course, without doing anything real): #include <iostream> #include <utility> struct element { element () { }; element (element&&) { std::cerr << "moving\n"; } }; struct container { void insert (const element& value) { do_insert (value); } void insert (element&& value) { do_insert (std::move (value)); } private: template <typename Arg> void do_insert (Arg arg) { element x (arg); } }; int main () { { // Shouldn't move. container c; element x; c.insert (x); } { // Should move. container c; c.insert (element ()); } } However, this doesn't work at least with GCC 4.4 and 4.5: it never prints "moving" on stderr. Or is what I want impossible to achieve and that's why emplace()-like functions exist in the first place?

  • Javascript onclick stops working, multiple dynamically created divs.

    - by Patrick
    I have run into a strange problem, i am creating a lot of dynamically divs. And i recently found out that some of my divs doesn't fire the onclick event? All the divs are created using the same template, so why are some not working? Most of the time, its the 4-5 from the bottom. If you click on one of the others and then try again, you might get one of those to trigger. But only sporadically. Code to create the divs: GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; var instance = this; if (fieldNumber == 6 || fieldNumber == 7 || fieldNumber == 17) { } else newField.onclick = function() { instance.DivClick(fieldNumber); return false; } this.fields[fieldNumber] = newField; this.score[fieldNumber] = 0; return newField; } I added the return false to the click function, but it still behaves strangely. Why are some not triggering? I create around 18 divs / player. But it happens even if i just create one player. Do i perhaps need to cancel the event once i am done with it? (Like the return false; is trying to do)

  • Assigning console.log to another object (Safari issue)

    - by Trevor Burnham
    I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. (Haven't tested in other browsers yet.) If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's part. (I get the same results in both browsers if I bind the console function to a prototype and then instantiate, rather than binding it directly to the object.) I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

  • Please recommend a CMS framework in Java good for making a monitoring system

    - by TiansHUo
    I already have Java code to display and process data from a database. I would now like to implement the code as modules, and incorporate as a whole into a CMS system. The CMS MUST support Spring, Hibernate, etc. The CMS MUST not be GPL, and preferably open source (lGPL, BSD,etc). The CMS MUST have good documentation and support The CMS MUST be secure (safe from XSS and injection) and support different levels of authorizations, (built-in or module) The CMS MUST have good navigation and tab, (built-in or module) +1, for having a good ajax paginated table module to display data +1, for using ajax to change pages with support for bookmarks and history.back() +1, for using jquery or prototype +1, for being easy to deploy, and easy to add modules +1, for supporting dynamically add/remove and drag-dropping of modules Please recommend a CMS best for the job. Thank you! EDIT: I don't need blogs or wikis or etc. I just want a framework where I can display paginated lists and time series graphs and log files. I will also host some pages for configuration. All of these code are already implemented.

  • Flex 4 front end connecting to Java Jersey Web Service

    - by user305801
    I created a Java REST service using Jersey. I use three of the HTTP "verbs" GET, POST and DELETE. I want to create several prototype front ends for the service. After much research, a lot dating to 2008 and 2009, I have been unable to find anything remotely simple. My three options are: 1) resthttpservice. This project hasn't been updated in a year. The only activity are one off suggestions that individual users have implemented. http://code.google.com/p/resthttpservice/ 2) Create an AIR application. This isn't unfeasible. 3) Writing my own socket level code but there is a security restriction with flash players and I need to implement a policy server. I have already read the question posted about asking whether using Flex for REST services were worth it. That information is old as well. I want to introduce REST services to my company but Flex's limited support for HTTP PUT and DELETE are discouraging. My service also uses the Accept header to determine if JSON or XML will be returned to the client. I can't seem to change HTTP headers without doing socket programming. I'm fine with that but the security policy thing is annoying. Is there an easy way to use Flex 4 with RESTful services that uses PUT/DELETE and the Accept HTTP header? Please help. I'm very frustrated.

  • A monkey could do this better - Access to and availability of private member functions in C++

I'm trying to write something like the following: class MyClass { // Peripherally Related Stuff public: void TakeAnAction(int oneThing, int anotherThing) { switch(oneThing){ case THING_A: TakeThisActionWith(anotherThing); break; //cases THINGS_NOT_A: }; private: void TakeThisActionWith(int thing) { string outcome = new string; outcome = LookUpOutcome(thing); // Do some stuff based on outcome return; } string LookUpOutcome(int key) { string oc = new string; oc = MyPrivateMap[key]; return oc; } map<int, string> MyPrivateMap; Then in the .cc file where I am actually using these things, while compiling the TakeAnAction section, it [CC, the solaris compiler] throws an an error: 'The function LookUpOutcome must have a prototype' and bombs out. In my header file, I have declared 'string LookUpOutcome(int key);' in the private section of the class. I have tried all sorts of variations. I tried to use 'this' for a little while, and it gave me 'Can only use this in non-static member function.' Sadly, I haven't declared anything static and these are all, putatively, member functions. I tried it [on TakeAnAction and LookUp] when I got the error, but I got something like, 'Can't access MyPrivateMap from LookUp'. MyPrivateMap could be made public and I could refer to it directly, I guess, but my sensibility says that is not the right way to go about this [that means that namespace scoped helper functions are out, I think]. I also guess I could just inline the lookup and subsequent other stuff, but my line-o-meter goes on tilt. I'm trying desperately not to kludge it.

  • Confused about UIView frame property

    - by slowfungus
    I'm building a prototype iPad app that draws diagrams. I have the following view hierarchy: UIView UIScrollView DiagramView : UIView TabBar NavigationBar And a UIViewController subclass holding all that together. Before drawing the diagram the first time I calculate the dimensions of the diagram, and set the DiagramView frame to that size, and the content size of the scrollview as well. -(void)recalculateBounds { [renderer diagram:diagram shouldDraw:NO]; SQXRect diagramRect = SQXMakeRect(0.0,0.0,[diagram bounds].size.width,[diagram bounds].size.height); self.frame = diagramRect; [(UIScrollView*)[self superview] setContentSize:diagramRect.size]; } I should disclose that the frame is being set to about 1500 x 3500 which i know is ridiculous. I just want to focus on some other parts of the app before I get into optimizing the render code. This works beautifully, except that the rect being passed to drawRect is not the size that I set, and my drawing is getting clipped at the bottom. Its close the size i set, but bigger in width, and shorter in height. Also of note, is the fact that if I force the frame to be much bigger than what I know the diagram needs, then the drawRect:rect is big enough, and no clipping occurs. Of course this has me wondering if the frame size needs to take into account some other screen real estate like the toolbars but my reading of the docs tells me the frame is in superview coordinates, which would be the scrollview so I reckon I need to worry about such things. Any idea what is causing this discrepancy?

  • Flex custom list selection not highlighting

    - by aip.cd.aish
    I want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this. Here is my code so far: <s:List width="400" height="220" dataProvider="{arrColl}" alternatingItemColors="[#EEEEEE, white]"> <s:itemRenderer> <fx:Component> <mx:Canvas height="100"> <mx:Image height="90" width="120" source="{data.imageSource}"></mx:Image> <mx:Label left="125" y="10" text="{data.title}" /> <mx:Label left="125" y="30" text="{data.type}" /> <mx:Label left="125" y="50" text="{data.description}" /> </mx:Canvas> </fx:Component> </s:itemRenderer> </s:List>
