  • Getting data from JFrame AFTER the form is filled

    - by mary jane
    I'm trying to get data for my application from a form set in an external window (getDataWindow extends javax.swing.JFrame). The problem is that functions are executed before form is filled in. getDataWindow dataW=new getDataWindow(); dataW.setVisible(true); size=dataW.returnSize(); I've tried also adding additional boolean variable to getDataWindow getDataWindow dataW=new getDataWindow(); dataW.setVisible(true); while(!dataW.checkIfReady()){wait();} size=dataW.returnSize(); But it makes also the window wait (it appears but it's black inside and nothing happens). I think i should create some threads for that - I've tried to call a window making function getDataWindow in java.awt.EventQueue.invokeLater(new Runnable()) but I had to initialize dataW earlier so dataW.checkIfReady() could be called, so it is a catch 22.

  • Ruby Methods: return an usage string when insufficient arguments are given

    - by Shyam
    Hi, After creating a serious bunch of classes, with initialize methods, loading them in IRb requires to look back at the code. However, I think it should be easy enough to return a usage message, instead of: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

  • How to allow certain HTML tags in a form field in Symfony 1.2

    - by camomileCase
    I'm playing around with Symfony and have encountered a road block. I created a model "CmsPage" which has a field called "content" which is stored as a clob (this is specific to doctrine I believe). When I created the app I set "--escaping-strategy=on" so if I enter any html when editing a CmsPage that gets encoded with html entities or something along those lines. I would like to allow html in this field and a quick googling hasn't helped much. Maybe I'm searching for the wrong terms. Anywho I would like to disable character escaping for this field and possibly only allow a small selection of html tags. What is the correct way to do this in Symfony?

  • Why isn't it possible to update an ObservableCollection from a different thread?

    - by MainMa
    In a multi-threaded WPF application, it is not possible to update an ObservableCollection from a thread other than WPF window thread. I know there are workarounds, so my question is not how to avoid the "This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread" exception. My question is, why there is such an exception? Why wasn't it possible to allow collection updates from any thread? Personally, I don't see any reason to block UI update when ObservableCollection is changed from other threads. If two threads (including parallel ones) are accessing the same object, one listening for changes of object properties through events, the other one doing changes, it will always work, at least if locks are used properly. So, what are the reasons?

  • Implementing traceback on i386

    - by markelliott2000
    Hi, I am currently porting our code from an alpha (Tru64) to an i386 processor (Linux) in C. Everything has gone pretty smoothly up until I looked into porting our exception handling routine. Currently we have a parent process which spawns lots of sub processes, and when one of these sub-processes fatal's (unfielded) I have routines to catch the process. I am currently struggling to find the best method of implementing a traceback routine which can list the function addresses in the error log, currently my routine just prints the the signal which caused the exception and the exception qualifier code. Any help would be greatly received, ideally I would write error handling for all processors, however at this stage I only really care about i386, and x86_64. Thanks Mark

  • What is the difference between Invoking and BeginInvoking a MessageBox?

    - by mafutrct
    In a form, compare BeginInvoke (new Action (() => { MessageBox.Show ()); })); with Invoke (new Action (() => { MessageBox.Show ()); })); What is the difference, and when should I use one over the other? How is the behavior affected by the message pump of the MessageBox? I did some testing and found that both methods block the UI. The only difference is that Invoke is actually called instantly while BeginInvoke takes a (very short) time until the code is run. This is to be expected.

  • Does it mean JVM Suspended?

    - by Joe.wang
    When my application run . I got a message says : Ping: Timed out waiting for signal from JVM. The JVM was launched with debug options so this may be because the JVM is currently suspended by a debugger. Any future timeouts during this JVM invocation will be silently ignored. What does that mean? It seems it will block any web request from outside? because when I upload a file to it, it failed. help me .

  • C#: Searching through arrays

    - by Jonathan Oberhaus
    I have a dvd app that stores dvds and blu-rays, I want to search the arrays by director. Below is the code for the inventory class I have seen many different ways to do this. There seems to be some debate as the best/most efficient way to accomplish this, any suggestions?

  • Small line-height cross-browser difference

    - by AESM
    So basicly my problem is that the line-heights in Firefox are a little bittle "larger" than in other browsers even though they're all fixed line-heights. For example, you have a block element which has a height from 100px and the line-height is set to 102px. Now, in Firefox the vertical alignment of text is perfect. But in the latest Chrome and Safari 4, the text stands 2px or so higher. Isn't there any way to fix this? Thanks.

  • Ignoring "Content is not allowed in trailing section" SAXException

    - by Paul J. Lucas
    I'm using Java's DocumentBuilder.parse(InputStream) to parse an XML document. Occasionally, I get malformed XML documents in that there is extra junk after the final > that causes a SAXException: Content is not allowed in trailing section. (In the cases I've seen, the junk is simply one or more null bytes.) I don't care what's after the final >. Is there an easy way to parse an entire XML document in Java and have it ignore any trailing junk? Note that by "ignore" I don't simply mean to catch and ignore the exception: I mean to ignore the trailing junk, throw no exception, and to return the Document object since the XML up to an including the final > is valid.

  • How to delay user login until RunOnce is completed? [Win XP]

    - by Shaitan00
    Currently I have an application that runs at startup when a user log's in to the account (administrative), as well as something under HKLM...\Run which is also executed - but I need to run something once and BEFORE both these things are executed. My solution was to use HKLM...\RunOnce which is executed before the HKLM...\Run but the task can take 30-45 seconds which gives enough time for the user Startup to be executed and launch the application prematurely. I thought of maybe including a SLEEP but RunOnce doesn't block the user account load... Then I considered the group policies but they do not have a RunOnce equivalent that I can use... Also I am not sure if Group Policy is run at the right time (never used it before). Is there anyway to make my RunOnce delay the account startup of my application, or a better place where I can execute it before both HKLM...\Run and user Startup? Or any recommended alternatives? Any ideas or help would be much appreciated... Thanks,

  • Maintaining Logging and/or stdout/stderr in Python Daemon

    - by dave mankoff
    Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

  • How can I tell that a NetTcp-based WCF connection was interrupted?

    - by mafutrct
    A WCF service is based on NetTcpBinding. It may happen that the client silently vanishes, leaving the server thinking that it is still connected. I'm currently using a thread that pings all connected client to see if they are still alive, and removes disconnected clients. Is a ping thread the correct way to solve the issue, or is there a better, possibly event-based way? Do I have to surround every code that communicates with the client by try/catch and remove it from the list of connected clients additionally?

  • Isolating read and write in multithreaded

    - by the_lotus
    Hi In a multithreaded application. I have a bunch of function that loop through a collection to read the information. I also have a bunch of function that modifies that same collection. I’m looking for a way to isolate all the read and the write together. I don’t want a write to be done while a read is in progress. I was thinking of using SyncLock on the collection object but this will block multiple read trying to work in parallel.
