Corona Shake Event Sensitivity - events

I created an app that shows images in an array in order when the user shakes the phone. However, the sensitivity is too bad, I really need to try hard to shake that and sometimes when I try hard, it just pass images too fast, so I can't see the first one thoroughly. Do you have any suggestion about that?

Will this honey pot work?

I just made my first super simple honey pot and am wondering if it will even work:
An input field floated -9999 left won't be visible to most humans. And there's a note saying "Don't write here" if they do see it.
An "onChange" event listens for change to that field and when it changes, it alerts ('You're spamming me!') and then redirects to Google.
I am wondering if this is too designed with a human in mind. Do bots fill the entire form out at one instant? Would a bot still be able to fill the form out if there's an alert on the page? Can I force the entity that's using the page to click the "OK" on the alert, effectively causing the bot to wait forever?
I am sure there are hugely robust systems that are out there but I'm looking for something very simple. I don't get so much spam that I can't handle it...just am frustrated winnowing through 300 spams each month trying to find the one or two new users who actually signed up.
Thank you for any help/suggestions!
Well, yes and no. Some bots will maybe fall for it and fill out everything, but others won't.
Redirecting with JavaScript doesn't sound like a very good idea, because most bots haven't got a JavaScript engine. You could use this fact to filter them - although you could also filter legitimate users.
You may also check how long it takes to get the user fill out the form - if it's too short, it's probably a bot.
Don't expect a 100% success rate, but a combination of techniques may already help a lot.

What could possibily slow down my flex mobile application?

I am working with flex for the last two years on some desktop apps. Until now I never had any performance related issues but today as we completed a mobile application for the iPad, I'm facing a challenge, the application is incredibly slow on the iPad.
http://i.stack.imgur.com/qkbWn.png
Slow, means that when I press a button in the menu to change the splitview I must wait something like 5s. Then scrolling is really slow two, with less than one fps and my TextInput starts to bug (the text is not in his box anymore).
I started to read a lot of blog post and presentation about optimisation for the mobile platform and then I rewrite some of the components I use. I removed the SkinnableContainer for instance and replaced it by a VGroup including some actionScript based drawing.
Now what you see is a VGroup (the dark grey one) containing some others VGroup (the group with title here) and then each widget is an HGroup with a label and a Widget. I only use Label and TextInput for the text.
Creation time is slow even (several seconds to create the view) for another page where there is only 4 text widget on it, or another one with only a list with a custom item renderer where each row is a set of 4 labels.
The whole things is cabled with RobotLegs, with nothing fancy, one models is injected in the view and at the beginning I set a member variable on the view with this object to bind my variables.
Frankly my thinking right now is : it smells fishy because if I've done everything right it is impossible to have such low performance and thinks that flex is competitive on the mobile platform. So right now I'm trying to disable the application piece by piece to try to locate what could slow it like that. I've got a couple suspects to check, for instance I've got some binding warning to check, and then see if robotlegs has got its share of the problem.
So my main question here is what do you think, and could you have some ideas about "is there a problem" and "how do we solve it".
Thanks
Run profiler for startup and separatelly for each operation that takes longed that it needs. Then prioritize the problems and try to solve them with basic optimization techniques.
Some problems you will not be able to solve fast - e.g. time for creating big components. The only option there is to rewrite those components with AS3 without MXML, styles and anything. I'm sure that flash.text.TextField is created many times faster than mx.controls.Label. The same for other components.
When component is created, it can be reused at a very low price. In your app there must be a lot of places where you recreate while you can reuse old components. It will save you memory and time.
Layouts tend to redraw even when it's not needed. If you have a lot of nested layouts, find the most critical places and replace a series of layouts with one custom layout or even component.
This all is very developer time consuming. At the end you will not get a smooth app anyway, but I believe that it can become usable.

pivot with in Panorma ....swipe both together

when i use pivot with in the panorama .pivot are used as a gallery view. i want to move pivot when i swipe it .but the problem is this because of both panorama and pivot are the same gesture event so both are they move .
i want swipe only my pivot view .
I would like some sample code or any other suggestion to do this.
so please give me a solution for doing this and
also give me a link where i easily understand this. Thanx in advance
You shouldn't have a Pivot in a Panorama control. End of discussion.
I believe it is achievable, because I've already solved similar issues with having WebBrowser control inside a custom horizontal-scrollable overview container like Pivot/Panorama, but believe me, it is NOT worth it. I've had to dig very deep into the visualstructure of the controls and attach my own manipulation-handlers to their viscera, manually choose which horiz/verti events to pass and which to cancel, and so on. This is not so easy, takes a lot of time, and doesn't guarantee that on the end you will have something behaving in a way you wanted to achieve in the first place. If you are not bound by some contract to preserve the shape of the UI, please, drop the idea and redesign your UI, just to save on your sanity and nerves.
But, if you are already insane or really want to dig where noone should, start on analysing your UI as a two rectangles: large pano and small pivo, and think which part should behave how on different possible touches/h-v swipes/h-v pans/pinches/so on. Write it down just to for reference, or soon you will probably start making small mistakes that will interfere with your understaning of the flow of the events.
I've checked the version I have, and "my" Panorama uses internally the UIElement.ManipulationXXXX events. In that case:
Display visualtrees of your UI and try attaching manipulation-events to every control. In those events, write/log which control's which handler was invoked. Then make some swipe/scroll on your APP and observe events. Analyze how they were bubbling and try cancelling (e.Handled=true) the manipulation-completed and/or manipulation-delta events somewhere between pivot and panorama. Your goal is to have the panorama see that e.Handled=true, while your pivot must see e.Handled=false. Your Pivot will probably see the event sooner than the Pano, so that point should be relatively easy.
If it fails to work, then you should check your version of the Pano, and check how it detects movements. If, for example, it uses the GestureListener - try the same trick with it. Etc.
And remember, you can always make your own horizontal-overwiew-container that will look like Pano, behave like Pano, and that will work with Pivo better - because it will be your code and you will tell it what and when to move. if you want to go this way, start on google and check all the preliminary Panorama previews that random people have published before that control was published by MS.

What will prevent LVN_ITEMACTIVATE from firing?

I am writing an app with raw windows API (opensource Win32++) where I have a ListView.
The problem I have now is that whenever an item in the ListView is clicked, the system/app will generate a warning tone/sound "ding". Furthermore, I noticed I cannot get the LVN_ITEMACTIVATE through item-dbl-click or item-keypress-enter, which would normally work if this problem had not occur.
Would anyone have any idea how this might be happening?
I believe there is nothing wrong with Win32++, it just could be one of the things I do is causing this. But my program has become quite big to dissect plus I have no idea where to start looking.
Thanks.
PS: I had my computer muted for the longest time, hence, I don't know when this started eventhough I had the listview since a long time ago. T_T
Start looking with a tool that can show you the Windows messages that the control generates and receives. Like Microsoft's Spy++. Compare it with a working list view to have an idea what might be amiss. Also check the parent window. I haven't otherwise heard of listviews that dingaling, the LVN_ACTIVATEITEM should fire the first WM_LBUTTONDOWN, no double-click necessary.

User interface paradigms that need changing?

Often times convention is one of the most important design consideration for user interface. Usually the advice goes to do it like Microsoft does.
This is for three reasons:
If it ain't broke, don't fix it.
If your users expect to click on a floppy disk icon to save, don't change the icon (even though some of them may have never seen an actual floppy disk).
Users don't want to re-learn the interface (and hot keys, etc.) with each different application they use.
At the same time Emmerson said "*A foolish consistency is the hobgoblin of little minds.*" So when does maintaining a consistent user interface cross the line from a good idea to stagnated innovation?
Microsoft shook up the good old WIMP GUI with the introduction of the tool bar, and then again with the Ribbon control (which is the natural evolution of the tool bar, like it or not.) Now we are seeing ribbons everywhere.
So my question is, what are some user interface paradigms that are accepted and consistent across multiple applications, but have stayed past their prime and are starting to reek? Are there some important changes that would benefit from a grass roots push by developers to innovate and improve the user interface experience for our users?
One thought that came to mind for me is the modal pop-up dialog. You know the ones that say: "Are you sure you want to . . .. - [Yes] [No] [Cancel] [Maybe]" and its evil twin "Successfully completed what you wanted to do! [OK]." We are seeing a movement away from these with the "info panel" in browsers. I think they need to be adopted in windows application development as well.
If possible please list a solution for each stale UI item.
And please don't list clippy. We all know he was a bad idea.
NOTE: This is specifically Windows client user interface paradigms, but I am certainly open to drawing inspiration from the web, the Mac, etc.
You mentioned popup modal dialogs , and I'd argue that non-modal ones are just as bad. Any dialog box remove focus from the program, they could end up behind the program and make it hard to find it, they might not even appear on the same virtual screen.
I'd like to see an end to all dialog boxes. If you need to stop someone from using the UI because of some non-normal circumstance, then remove the relevant parts of the UI from the window, and replace it with what the dialog would contain. Bring back the UI once the problem has been handled.
Clicking things on touch interfaces
It's incredibly difficult to click on things on a touch interface, because you don't know when you have pressed the screen hard enough. And if you add an animation to the button you are clicking, you most likely wont see it, because your finger is in the way. Adding other reactions, like vibrating the phone or painting waves on the screen might work, but there is usually a delay which is too large, much larger than the tactile sense of a button being pressed. So until they invent a screen with buttons that can be pressed, all touch devices should move towards dragging user interfaces (DUIs) instead.
Counter intuitively it is easier to press an object on the screen, drag it, and then release it than it is to just press and release it. It's probably because you can see the object moving when you start dragging, and you can adjust the pressure while dragging it. Dragging also has a lot more options, because you now have a direction, not just a point that you clicked. You can do different things if the user drags the object in different directions. Speed might also be used, as well as the point where the user releases the object. The release point is the real strength of DUIs, because it is very easy to release something, even with pixel precession.
Some designs have started to use DUIs, like (here we go) the iPhone, palm pre and android phones. But only part of their design is DUI, the rest is clicking. One area they all have in common is the keyboard. Instead of clicking on a key the user presses any key, then drags their finger towards the key they really wanted to click. Unlocking these phones also uses dragging.
Other easily implemented DUI features would be things like mouse gestures, where dragging in different directions, or drawing different shapes does different things. There are also alternate keyboards being researched which puts a bigger emphasis on dragging. All buttons can be changed into switches, so have to drag them down a bit to click them. With a well designed graphics, this should be intuitive to the user as well.
The Apple Human Interface Guidelines are a good read on this topic. They discuss this from a very broad point of view and the guidelines apply to any platform, not only Mac.
The file system. I want to save a file.. >OOOPs I need to think of a file name first. Well.... how about ... blah.doc.
6 months later...
Where the %#*(%& * did I save that %()#*()*ing file?
The solution is build a versioning system into the application, or better, the OS. Make files findable by their content, with a search engine, instead of forcing the user to come up with a memorable name, when all they want is for their file to not get lost.
Eliminate the save step. Type something in to the application, and it's just there, and there's no risk of losing it by some misstep, like forgetting to save. If you want an older version, you can just pick a date and see what the document looked like back then.
To build on the search engine idea: It's a pain having to navigate some arbitrary tree structure to find your stuff. Searching is much easier. However, you might still want to have something like a "folder" to group multiple files together. Well, you can build a richer metadata system, and have a "category" or "project" field, and setup the search engine to show items by project, or by category. Or group by those, or whatever new UI discovery we make next.
This question is a bit too open-ended, IMHO.
However, my main approach when designing anything is:
Fits in to wherever it is. If it's a windows app, I copy MS as much as a possible
It's simple.
It provides options
Buttons have a nice description of what the result of clicking will be, as opposed to 'yes or 'no'
Harder to answer the rest of your post without spending hours typing out an arguably useless (and repeated) set of guidelines.
In my mind, the one thing that really stands out is that USERS need more and easier control over the application's user interface appearance and organization.
So many interfaces can not be modified by the user so that the most used/favorite functions can be grouped together. This ability would make your favorite software even easier for you to get things done.
Error messages need a "Just do it!" button.
Seriously, I really don't care about your stupid error message, just DO WHAT I TOLD YOU TO DO!!!
I think the entire Document model of the web needs to change. It's not a user interface, but it leads to many, many bad user interfaces.
The document model was a good idea to connect a bunch of documents, but now the web is also a collection of applications. Today, I think the Page/document model corrupts our thinking. We end up lumping things together that aren't related, modularizing our code wrong, and in the end confusing users with our monolithic control board type websites.
Find dialogs that sit over the widget in which you are doing the search are terrible. Loads of apps do that. The find bar in Firefox works much better.
Many applications have multiple panes within the UI - eg in Outlook there's the preview pane and the inbox pane (amongst others). In these applications typically cursor key presses apply to the currently focussed pane. But there's very poor hinting to show the user which pane has focus and there are seldom keyboard shortcuts to move the focus between panes.
The focussed pane should be highlighted somehow.
Something like alt+cursor keys should move the focus around.
Ctrl-Tab and Ctrl-Shift-Tab cycle left and right through tabs instead of MRU behavior, even though in most cases the same behavior is duplicated with Ctrl-PageUp and Ctrl-PageDown.
There are a lot but here's an idea for a couple of them:
Remove some clicks like in "add another" or "search item" and the like.
This is well done with interfaces like ajax which have autocompletes ( and auto search ) but is slowly being adopted for platform UI's ( and in some cases they were originated in platform UI's. )
This is how StackOverflow does it for some scenarios.
But of course, we all know that already don't we? No need for "Seach tag" or "Add another tag" buttons, they just happen
Dialogs as you described.
Guys at Humanized proposed Transparent messages which actually are used in their product Enso and some other places.
Mac uses them for notifications ( like in Growl ) use them very well, or Ubuntu new notification system.
alt text http://blogs.sun.com/plamere/resource/NowPlayingGrowl.png
Firefox replaces the traditional "Search" dialog box with a search bar at the bottom.
Although not everyone likes the placement for next/previous as in this screenshot
And even SO ( again ) :) replace the notification with the yellow bar.
Finally:
File managers
I really like ( sometimes ) the simplicity of regular file managers, but some times I would like to work faster/better with them.
If you compare IE 4 with IE 8 you can tell the advance ( even better compare IE 4 with Google Chrome )
But if you compare Windows 95 Explorer with Win XP they are almost the same!! ( Win Vista/7 is a step forward )
But I wonder: Why haven't file managers improved as much as webbrowsers?
That's one reason I like stuff like QuickSilver but it is just a step. Much work is needed to create something like a "Perfect program launcher" or (FileManager/DesktopSearcher etc as you wish )
QuickSilver featuring "move to" action
