You may grab the innerHTML of the page and then process it on the server: document.getElementsByTagName(‘html’)[0].innerHTML; // this would also be interactive (i.e. if you’ve // modified the DOM, that would be included)
Depending on the regular expression implementation you can use so called non-capturing groups with the syntax (?:…): ((?:a|b)c) Here (?:a|b) is a group but you cannot reference its match. So you can only reference the match of ((?:a|b)c) that is either ac or bc.
Have you set the KeyPreview property of the form to true? That will cause the form to get a “first look” at key events. Update: getting this to work properly when a Button has focus seems to be a bit tricky. The Button control intercepts the arrow key presses and moves focus to the next … Read more
As Kenny has noted in his comment, you can get around this with: List<Test<? extends Number>> l = Collections.<Test<? extends Number>>singletonList(t); This immediately tells us that the operation isn’t unsafe, it’s just a victim of limited inference. If it were unsafe, the above wouldn’t compile. Since using explicit type parameters in a generic method as … Read more
There isn’t any need for a third-party DLL. This simple method captures the current screen image into a .NET Bitmap object. private Image CaptureScreen() { Rectangle screenSize = Screen.PrimaryScreen.Bounds; Bitmap target = new Bitmap(screenSize.Width, screenSize.Height); using(Graphics g = Graphics.FromImage(target)) { g.CopyFromScreen(0, 0, 0, 0, new Size(screenSize.Width, screenSize.Height)); } return target; } I am sure you … Read more
Photos taken by the ACTION_IMAGE_CAPTURE are not registered in the MediaStore automatically on all devices. The official Android guide gives that example: http://developer.android.com/guide/topics/media/camera.html#intent-receive But that does not work either on all devices. The only reliable method I am aware of consists in saving the path to the picture in a local variable. Beware that your … Read more
The following works for me: public static Bitmap getVideoFrame(FileDescriptor FD) { MediaMetadataRetriever retriever = new MediaMetadataRetriever(); try { retriever.setDataSource(FD); return retriever.getFrameAtTime(); } catch (IllegalArgumentException ex) { ex.printStackTrace(); } catch (RuntimeException ex) { ex.printStackTrace(); } finally { try { retriever.release(); } catch (RuntimeException ex) { } } return null; } Also works if you use a … Read more

I had a Java based app. that used Java Sound to tap into the sound flowing through the system to make a trace of it. It worked well on my own (Windows based) machine, but failed completely on some others. It was determined that in order to get it working on those machines, would take … Read more
Capture conversion was designed to make wildcards (in generics), ? useful. Suppose we have the following class: public interface Test<T> { public void shout(T whatever); public T repeatPreviousShout(); } and somewhere on our code we have, public static void instantTest(Test<?> test) { System.out.println(test.repeatPreviousShout()); } Because test is not a raw Test and since repeatPreviousShout() in … Read more
