I recently got small action camera called sq23. I used it few times outdoors, found that I never take picture instead of video. But from stand-by state to video-ready state is tough, so I want to change the function of buttons in this camera.
I know how to program, but I don't know to access the code that original functionality is implemented. Can you provide some procedure or tools for accessing the original code?

I want to add a button to my flash game (AS3) and on click it saves a picture of the current users whole screen and saves it to pictures/disk automatically, but I don't know how to do that, I know how to add the button to the UI and add a click event and all that, just need to know how to make it save a picture of the current screen to disk (doesn't have to be just the flash screen, can be the WHOLE screen of the users pc, either way works!)
I was on my way writing you the answer but I found this post have a better explaination: Is it possible to capture the screen and save the image in actionscript 3?
"Yes, it's possible.
Draw some display object to a BitmapData (the stage, for example) and crop it if neccesary (the second param of BitmapData::draw will help you out here).
Then, convert the raw pixel data to JPEG or PNG using some encoder. I'm sure up to this point, this is what those tutorials will explain you how to do.
Now, the third step is different but simple enough. Instead of sending the image data to a server side script, use a FileReference object. Since Flash Player 10, it has a method called save, that prompts the user to save a file locally.
Since this is a desktop app, you could also make it an AIR app. This will give more direct access to the file system and other features, in case you need them."
So, I'm pretty much a beginner in Flash and Actionscript (using AS3, as I said in the title), and I'm trying to make a basic escape the room game. I haven't gotten far, and right now that's because every time I test my game (or publish preview it) the graphics get this annoying outline. Here it is when tested: http://i305.photobucket.com/albums/nn228/chokingondrama/flash.png
Every outline corresponds to some object present in the game, most of which have an alpha component of 0 since they're on different sides of the room. This didn't happen before, but once I added the code that allowed the player to change their view with the arrow (each viewpoint/wall is a different frame) these appeared.
It's a little different when published to HTML, basically it just gives each image a white background: http://i305.photobucket.com/albums/nn228/chokingondrama/html.png
Also, it would be nice if somebody could give me advice on how to make sure importing to flash won't result in lower quality.
Thanks in advance. If needed, I'll post any part of the code.
Some tips:
Don't set alpha to 0, instead use the visible property, setting movieclip.visible = false will make it a lot more efficient.
As for the importing and quality, after you import to stage or library, bring up the library (ctrl + l), and right click on the file you imported, go to properties. If it's an image, set compression to lossless, and allow smoothing.
For audio, go to file-> publish settings, and change audio stream and audio event (whichever you might use) to 128kbps.
As for your main question, I need more info, if you want you can post your source. It might be because of how you are placing your graphics on the stage.
For each of your MovieClips in question:
Try disabling button mode and see if the rectangles go away.
movieClipName.buttonMode = false;
If that doesn't help, or you really want button mode, try setting
movieClipName.tabEnabled = false;
There's a chance that since you added keyboard interaction each of your MovieClips are now expecting to be selected by the user when they press the tab key, much like any normal web form.
tabEnabled in the docs
You could also try
movieClipName.focusRect = false;

I am using the Map control in Windows Phone 8.
I need to implement a page where user can select his location using the map control.
I am trying to know when the app was first manipulated by the user.
Some background info:
I saw that when the control is shown, it automatically centers the world map, and CenterChanged event is raised.
I am not able to understand how ManipulationStarted, ManipulationDelta and ManipulationCompleted work.
the first time I drag, ManipulationStarted is not called, only ManipulationCompleted.
I could consider the first manipulation by user as being the 2nd time the CenterChanged is fired.
But this is a hack or a guess, I am not happy not having a good understanding how it works.
The Map control intercepts and handles Manipulation events and as such you don't get all of them. Remember, once routed events are marked at e.Handled=true they no longer bubble up.
Depending on your Scenario WP8 exposes the UseOptimizedManipulationRouting property which might prove useful. Setting UseOptimizedManipulationRouting=false causes Map, Pivot and other controls to not swallow events for nested controls.
If that doesn't help, have a look at the following Nokia Wiki article where the author ran into the same problem as you did and used Touch.FrameReported to get out of it # http://www.developer.nokia.com/Community/Wiki/Real-time_rotation_of_the_Windows_Phone_8_Map_Control
I just started to study the Model View Controller pattern. I now understand the basic usage of MVC, but when i tried to implement MVC in a simple test, i ran into a problem. Ofcoarse I could easily adjust the code so it works, but I wish to learn how to correctly implement the MVC pattern.
The test:
I used actionscript 3 to make a simple program. It consist of a turret, and a mouseclick. The turret is in the middle of the screen. When I click anywhere the turret rotates towards the point where I clicked. Both the mouse and the turret have their own model,view and controller. When I click, the MouseModel changes correctly. But for the actual TurretView to respond, the TurretModel must change its rotation variable and send out an event.
The question is who responds to the MouseModel event?
/------->MouseControl------\
/ \
MouseView ?<---MouseModel
TurretView <------------------TurretModel
TurretControl
I figured its best not to have MouseModel directly influence TurretModel or TurretControl, because this would require them to be an eventListener. Making TurretView listen to the MouseModel, and then tell TurretControl to adjust TurretModel, after wich TurretView can update trough a TurretModel event looks like a lot of extra code for a simple task. Also I'd rather not have MouseControl affect TurretModel, this would break the flexibility of the mouse as input for future classes.
Ow, also in which class do I put the code for the angle calculation?
Thanks in advance
Remember that the goal with MVC is primarily the separation of Model and View, and the Controller can serve as the communicator between the two.
Unless you are planning on storing each action that occurs (clicking, rotating, etc.), there is no real need for an action (in this situation) to send data to the Model. Everything you'd like to do should be easily handled with the Controller. So the flow would be:
Mouse click
Event is fired to trigger a command (in the Controller), passing along the mouse location
The command calculates the turret's rotation
The command tells the View to rotate the turret
This is, of course, my suggestion based off of your example. In truth, depending on the project, the above flow could easily change (for instance, in this situation it seems good to do rotation calculation in the command, but in other situations that may not make as much sense). Look at MVC as a goal - you're trying to separate these elements as much as possible, but there is no 100% "works-every-time" way to do it.
Robotlegs, a popular MVC framework, has a great diagram on their site showing how they tackled MVC:
http://www.robotlegs.org/diagram/
I'm not advertising that you NEED to use Robotlegs (it's good, but there's plenty of other alternatives), but they definitely made a pretty diagram :)
You should have one model, which then has pieces in it that you are currently calling MouseModel and TurretModel. You can either keep those names and breakdowns, or do something else once you have a better "handle" on what needs to be done.
The View that is tracking the mouse clicks should dispatch an event that your Controller component catches to update the TurretModel (at this point, there's probably no need for a MouseModel). Your TurretView can then update itself based on the TurretModel, or the Controller can update the TurretView based on the new value. This will depend on how you have it wired.
Usin a Framework such as Robotlegs can help you figure out all the ins and outs of this process, and I've heard that this book http://shop.oreilly.com/product/0636920021216.do provides a great explanation of MVC, even if you don't choose to use Robotlegs after you read it.
I am making a Flash puzzle game. When the user loads the game, it needs to ask whether to resume the game from the last state (if it exists). I have a serialization system in place, but I need to ensure that the loaded state is definitely the last state.
One solution is to save the state to a SharedObject every time the state changes (when the player makes a move). However, the game state sometimes includes a countdown, so I'd have to be constantly (or periodically) saving the state in order to retain it. I guess this is acceptable, but it seems kludgey.
Is there any event which is fired when the swf is closed? Or anyone else have another elegant solution to this?
(I'm not using AIR, but solutions requiring AIR are appreciated.)
Edit: Another important point is that I may not have control over the embedding HTML for the game, as it may be syndicated to many sites. So solutions involving javascript aren't ideal.
If your Flash is hosted on a HTML page, you can use the 'Window is closing' event notification to fire a message into your Flash object either using old-skool GetVariable() or new-stylee FlashCall() mechanisms.
Whether you'll actually be able to persist state before your Flash object is destroyed is another question... you could always do the (evil) 'Are you sure you want to close/navigate away from this window?' alert that some sites use.
Handling DOM Events in Flex
HTML 5 events
The on-close event sounds the right solution, but I wonder if you could 'split' your serialisation? i.e. save the full puzzle state on each move, but also have a secondary 'lightweight' state for your countdown (or anything similar) which could be updated each time the countdown changes.
That may be easier than trying to catch the close event and save before the page is destroyed (especially as browsers are not consistent in this area).
this one should help you
