Is there a non-blocking version of MessageBox.Show (or something like it)?
You need to use multi threading to perform this task in which one thread (the main thread) will do the processing and the other thread will be used to show the messagebox.

When does a UDP sendto() block?
This can happen if you filled up your socket buffer, but it is highly operating system dependent. Since UDP does not provide any guarantee your operating system can decide to do whatever it wants when your socket buffer is full: block or drop. You can try to increase SO_SNDBUF for temporary relief. This can even … Read more
Is the UNLINK command always better than DEL command?
Before discussing which one is better, let’s take a look at the difference between these commands. Both DEL and UNLINK free the key part in blocking mode. And the difference is the way they free the value part. DEL always frees the value part in blocking mode. However, if the value is too large, e.g. … Read more
Does a thread waiting on IO also block a core?
A CPU core is normally not dedicated to one particular thread of execution. The kernel is constantly switching processes being executed in and out of the CPU. The process currently being executed by the CPU is in the “running” state. The list of processes waiting for their turn are in a “ready” state. The kernel … Read more
What is meaning of ‘Blocking’ in Firebug Net Panel?

As far as I know number of persistent connections by default is limited in last versions of Firefox to 6, IE8 also 6. Earlier it was only 2. It can be changed by … Read more

Click the vertical ellipsis icon (or the gear icon on older versions) in the upper right and go to settings. See if the “Disable JavaScript” … Read more
In Go, does it make sense to write non-blocking code?
Blocking and non-blocking aren’t really about performance, they are about an interface. If you have a single thread of execution then a blocking call prevents your program from doing any useful work while it’s waiting. But if you have multiple threads of execution a blocking call doesn’t really matter because you can just leave that … Read more
Wrapping an asynchronous computation into a synchronous (blocking) computation
Using your own Future implemenation: public class BazComputationFuture implements Future<Baz>, BazComputationSink { private volatile Baz result = null; private volatile boolean cancelled = false; private final CountDownLatch countDownLatch; public BazComputationFuture() { countDownLatch = new CountDownLatch(1); } @Override public boolean cancel(final boolean mayInterruptIfRunning) { if (isDone()) { return false; } else { countDownLatch.countDown(); cancelled = true; … Read more
How to prevent downloading images and video files from my website?
No, it’s not possible. If you can see it, you can get it.
Java InputStream blocking read
The underlying data source for some implementations of InputStream can signal that the end of the stream has been reached, and no more data will be sent. Until this signal is received, read operations on such a stream can block. For example, an InputStream from a Socket socket will block, rather than returning EOF, until … Read more
