I just want to know, is it possible to open camera instance and take a picture online.
in other words, if i have an app has an access to the internet can i create a button to open the camera and take a picture while i'm being online?
Why not instead just use the toImage() function of all views (including a WebView) that Titanium provides. This will give you a screenshot.

I've been playing with a generic usb camera to take snapshots every few seconds. With the help of this SO question, I was able to get the camera working; however, when you click the button to connect to the camera, a dialog box appears.
The difference between the other question and my question is that I have two video sources: a built in webcam and a usb camera. I also intend to have multiple cameras connected, all taking pictures. It appears that when you have multiple devices, you always get the dialog box where you have to choose the device. I'm trying to automatically choose the camera (and eventually cameras, plural) without this dialog box.
There are other pieces of sample code that I have played with - samples that have a device listbox that is populated; I thought this was what I needed (and I'd just remove the listbox control and process the list and what to connect to in code), but every one of these samples populates the listbox with "Microsoft WDM Image Capture (Win32)" instead of the devices listed in the dialog after attempting to connect to this "device."
Surely there's a way to automate the webcam(s) I'm connecting to instead of having to choose it from a dropdown in a Windows dialog, right? How would I go about doing this?
The solution ultimately was to use EMGU to access the camera; this also allows for connecting to multiple cameras at the same time.
Ocean2013.1 provides a sample(WheelerViewer) for using cameras(OpenInventor features) for 3D Windows, but is it possible to synchronize(equivalent of clicking the camera link toolbar option) multiple intersection windows in Ocean/Petrel programmatically?
Camera linking is available as a Petrel feature but not as a Ocean API for developer to access programmatically
You need to be mode specific on what you are trying to synchronize and why.
The Window3D exposes enough camera API that one can write his own camera view synchronization.
If all you want is to be able to click the "Synchronize camera" button via API, it's a different issue. Why do you need this? Often users ask to be able to link all windows with one mouse button click. This, I believe, might be coming in 2015 as a user feature.
I'm trying to find a way to get a live view of a specific window. In the same way that Mission Control and Exposé will show you live views of windows that are currently obscured by other windows (this is also done by Hyperdock, so I'm pretty certain that its not a private API).
What is the functionality called? And so where is the documentation on it?
You want the Quartz Window Services API. Basically, you want to create a window list with the windows you're interested in and use CGWindowListCreateImage to get a picture of the window's contents.
Is there away to copy a screenshot directly into an Adobe Air (2) application?
Kinda like this: User presses the "print screen" button and the screenshot shows up in the app.
Also I'ld like to know if pasting via keyboard or right-click work for that?
I'm new too AIR.
Best, John
Yes, it can be done.
But no, not directly from Air, unless you wish to capture parts of your own AIR UI (which should be no problem as these are within the scope of the AIR Application)
To capture the whole screen you would need to use an ANE (Adobe Native Extension) which can be written
both for iOS and Android devices and used from within AIR via an API.
Introduction to ANE Development:http://help.adobe.com/en_US/air/extensions/air_extensions.pdf
The following post discusses on the way by which an Air ANE can capture a screenshot (which is technical and relevant for developing such an ANE for Android)
How Native Extension take screenshot on Android device?
Other then this you might try a workaround, that is, instructing the user to capture using his own device's capture combination, then simply ask them to select the file from the Gallery, if indeed this is your intention...?
I am looking for a way, to check if my user is connected to the internet / cellular data when they navigate to a certain view of my application. I want this to occur pretty much when they press the button to take them to that view so the following occurs;
If they do have internet connectivity, it loads up a UIWebView which a coded in URL.
If they do not have internet connectivity, then it displays a static image instead.
First of all I guess i want to know if this is possible, and secondly the most efficient way of handling it.
Thanks
The way most of us deal with this is by using the Apple-written piece of code called Reachability. It can both pro-actively test for network connectivity, and set up a watcher to notify you when network connections status changes.
In the sample project behind that link, you want to bring the Reachability.m and .h into your project, then use the AppDelegate as a demonstration of how to use it.
