    - by ozlegolas
    Hi, I have two events for two seperate components, but there is a problem. JTabbedPane's stateChanged event is fired before JFormattedField's focusLost event. Is there a way of making stateChange event to be fired after focusLost event. Thanks, Tuna

  • How do I mirror a MySQL database?

    - by user366133
    I'm running two load balanced servers for one website, and I'd like the databases to be synchronized. Queries may be run on either of the two servers because they are both production sites, so the replication can't just work one way. It doesn't have to be in real-time, just fairly accurate so people don't notice a difference when they get switched to a different server.

  • How can I retrieve all the returned variables from a function?

    - by user1447941
    import random def some_function(): example = random.randint(0, 1) if example == 1: other_example = 2 else: return False return example, other_example With this example, there is a chance that either one or two variables will be returned. Usually, for one variable I'd use var = some_function() while for two, var, var2 = some_function(). How can I tell how many variables are being returned by the function?

  • Are there any C++ style and/or standard example files available?

    - by Harvey
    While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

  • Workflow for reading and writing files

    - by AIR_PhillipSenn
    In Workflow for reading and writing files the authors use these two lines of code: var file = air.File.documentsDirectory; file = file.resolvePath("AIR Test/testFile.txt"); But I think that it's using one variable for two different meanings, isn't it? Wouldn't it be better to write them as: var myDocumentsDirectory = air.File.documentsDirectory; var myTestFile = myDocumentsDirectory.resolvePath("AIR Test/testFile.txt");

  • A better javascript to string function?

    - by Jeff
    Before I go and create this myself, I thought I'd see if anyone knows a library that does this. I'm looking for a function that will take something in Javascript, be it an array, an associative array, a number, or even a string, and convert it to something that looks like it. For example: toString([1,2,3]) === '[1, 2, 3]' toString([[1,2], [2,4], [3,6]]) === '[[1,2], [2,4], [3,6]]' toString(23) === '23' toString('hello world') === 'hello world' toString({'one': 1, 'two': 2, 'three': 3}) === "{'one': 1, 'two': 2, 'three': 3}"

  • Getting screen height before first display?

    - by Mark
    Hi, I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided. How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows, Thanks
