问题 Is there a way to open one app from another app in Air? Example: I open app A which contains a button that opens app B when clicked.

问题 My code to do this uses reflection and strings that I give it, instead of user input. Ultimately I would like the user to be able to say "float" "2.0" and have the computer say, yeah, that's a float, or "bool" "abc" to which the computer would say, that's no boolean it's heard of. It would be simple enough to take the user input and convert it to a primitive type name, like "string" to "System.String", "float" to "System.Single", etc. (although if you know of a function to do that, that would

问题 This question already has answers here : Starting JavaFX from Main method of class which doesn't extend Application (3 answers) Closed 4 years ago .

问题 Im using the ExecutorService in Java to invoke Threads with invokeAll() . After, I get the result set with future.get() . Its really important that I receive the results in the same order I created the threads.

问题 I have a server application that receives information over a network and processes it. The server is multi-threaded and handles multiple sockets at time, and threads are created without my control through BeginInvoke and EndInvoke style methods, which are chained by corresponding callback functions. I'm trying to create a form, in addition to the main GUI, that displays a ListBox item populated by items describing the currently connected sockets. So, what I'm basically trying to do is add an
