  • The String source is unknown while using the parse methode!

    - by kawtousse
    Hi everyone, to parse a string to a date sql valid: SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd"); java.util.Date date = null; try { date = df.parse(dateimput); } catch (ParseException e2) { // TODO Auto-generated catch block e2.printStackTrace(); } with dateimput is what i get from my form like that: String dateimput=request.getParameter("datepicker"); but when running see the error: java.text.ParseException: Format.parseObject(String) failed at java.text.Format.parseObject(Unknown Source) at ServletEdition.doPost(ServletEdition.java:70) so it mean that dateimput is not known + I note that it is correctly dislayed when: System.out.println("datepicker:" +dateimput); Thanks.

  • How to prevent Debug.Assert(...) to show a modal dialog

    - by Martin
    I have a couple of libraries which use Debug.Assert(...). I think that the Debug.Assert(...) are fine and I still want them to execute, but I don't want them to block the execution of my application. Ideally, I would only like them to be logged somewhere. Given that I can't change the code of the libraries (and that I still want to compile in debug and run the assertion), how do I prevent Debug.Assert(...) to show a modal dialog? Thanks!

    - by Nikesh Yadav
    Hi Forum, I am new to Blackberry development (I am using Eclipse with Blackberry plug-in), I am trying to read a text file, which I placed in the "src" folder of my Blackberry project and this text file just contain a word "Test". when I run the program, I gets "UncaughtException: java.lang.outofmemoryerror". Here is the code I am using, where "speech.txt" is the file I am trying to read and is placed in the "src" folder - public class SpeechMain extends MainScreen { public SpeechMain() { try { Class myClass = this.getClass(); InputStream is = null; is = myClass.getResourceAsStream("speech.txt"); InputStreamReader isr = new InputStreamReader(is); char c; while ((c = (char)isr.read()) != -1) { add(new LabelField("" + c)); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); add(new LabelField(e.getMessage())); } } } Thanks in advance. Thanks, Nikesh

  • Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

    - by ?????
    My catalina logs are filling up with gobs of statements like: /logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4] [0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb] [0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8] on and on forever. I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here: http://hc.apache.org/httpclient-3.x/logging.html And I don't see where this logging as been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it. Any ideas? I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

  • Handling Exceptions that happen in a asp.net MVC Controller Constructor

    - by Jason
    What's the best way to handle exceptions that happen from within a controller's constructor? All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory. Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky. If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve. Am I missing something here, or has anyone else dealt with this?

  • How can I capture a multiline pattern using a regular expressions in java?

    - by lampShade
    I have a text file that I need to parse using regular expressions. The text that I need to capture is in multiline groups like this: truck zDoug Doug's house (123) 456-7890 [email protected] 30 61234.56 8/10/2003 vehicle eRob Rob's house (987) 654-3210 [email protected] For this example I need to capture truck followed by the next seven lines.In other words, in this "block" I have 8 groups. This is what I've tried but it will not capture the next line: (truck)\n(\w). NOTE: I'm using the program RegExr to test my regex before I port it to Java.

  • Trying to create scrolling horizontal thumbnail navigation that hides on left side when not in use

    - by user346602
    Hi, I am trying recreate the following type of scrolling thumbnail navigation as described in the following tutorial: http://tympanus.net/codrops/2010/05/10/scrollable-thumbs-menu/ I require my thumbs to slide out horizontally from the left. I have amended the code to the best of my abilities, but I can't get it to work. (Think the problem is in the top third of the jquery). Here is what I have to date: HTML <ul class="menu" id="menu"> <li> <a href="#"></a> <div class="sc_menu_wrapper"> <div class="sc_menu"> <a href="#"><img src="images/gallery/1.jpg" alt=""/></a> <a href="#"><img src="images/gallery/2.jpg" alt=""/></a> <a href="#"><img src="images/gallery/3.jpg" alt=""/></a> <a href="#"><img src="images/gallery/4.jpg" alt=""/></a> <a href="#"><img src="images/gallery/5.jpg" alt=""/></a> </div> </div> </li> </ul> CSS /* Navigation Style */ ul.menu{ position: fixed; top: 0px; left:0px; width: 100%; } ul.menu li{ position:relative; width: 100% } ul.menu li > a{ position:absolute; top:300px; left:0px; width:40px; height:200px; background-color:#e7e7e8; } /* Thumb Scrolling Style */ div.sc_menu_wrapper { position: absolute; right: 0px; height: 220px; overflow: hidden; top: 300px; left:0px; visibility:hidden; } div.sc_menu { height: 200px; visibility:hidden; } .sc_menu a { display: block; background-color:#e7e7e8; } .sc_menu img { display: block; border: none; opacity:0.3; filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30); } JQUERY $(function(){ // function to make the thumbs menu scrollable function buildThumbs($elem){ var $wrapper = $elem.next(); var $menu = $wrapper.find('.sc_menu'); var inactiveMargin = 220; // move the scroll down to the beggining (move as much as the height of the menu) $wrapper.scrollRight($menu.outerHeight()); //when moving the mouse up or down, the wrapper moves (scrolls) up or down $wrapper.bind('mousemove',function(e){ var wrapperWidth = $wrapper.width(); var menuWidth = $menu.outerWidth() + 2 * inactiveMargin; var top = (e.pageX - $wrapper.offset().right) * (menuWidth - wrapperWidth) / wrapperWidth - inactiveMargin; $wrapper.scrollRight(right+10); }); } var stacktime; $('#menu li > a').bind('mouseover',function () { var $this = $(this); buildThumbs($this); var pos = $this.next().find('a').size(); var f = function(){ if(pos==0) clearTimeout(stacktime); $this.next().find('a:nth-child('+pos+')').css('visibility','visible'); --pos; }; // each thumb will appear with a delay stacktime = setInterval(f , 50); }); /// on mouseleave of the whole <li> the scrollable area is hidden $('#menu li').bind('mouseleave',function () { var $this = $(this); clearTimeout(stacktime); $this.find('.sc_menu').css('visibility','hidden').find('a').css('visibility','hidden'); $this.find('.sc_menu_wrapper').css('visibility','hidden'); }); // when hovering a thumb, change its opacity $('.sc_menu a').hover( function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'1.0'},400); }, function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'0.3'},400); } ); }); Wondering if some eagle eye might be able to point out where I am going wrong. As my knowledge of JQuery is limited, I'm guessing it is in there. I really appreciate anyone taking the time to look this over. Thank you!

  • Why won't my span do a JQuery event click when I click it?

  • IE not blocking javascript

    - by Corey Hart
    It seems that IE8 defers javascript, but also doesn't block. I've setup a test environment to prove this. Here's the html page(replace 192.168.1.xxx with your server): <html> <head> <title>IE Pains</title> <script type='text/javascript' src='http://192.168.1.xxx/ietest/js.js'></script> <script type='text/javascript'> scream('hello world'); </script> </head> <body> </body> </html> And the js File: function scream( str ) { alert( str ); } Am I seeing this wrong, or does IE not recognize the scream function because it hasn't finished loading js.js?

  • Which event handler to use to record leaving page - onunload or onbeforeunload?

    - by symcbean
    Hi all, Having not any answers to my previous questions about using javascript to measure page turn times, I'm going to start writing my own code (!). To measure the length of tie it takes, I'm proposing dropping a cookie containing a timestamp when the user browses away from a page, then in a subsequent page, comparing that time with 'now' and sending back a request to a URL which will log the interval. It seems that there are 2 possible handlers I could associate the first block of code with - the onunload() handler or the onbeforeunload()? It's more important that it fail silently on browsers with no/broken support for the handler, than it be portable across every possible browser. Any pointers? Gotchas? TIA C.

  • How do I visualize a complex graph in .Net?

    - by Ivan
    I need to visualize a graph (technically being a set of Entity Framework objects, but I can translate it to another representation if needed) of this kind. I don't know how to name it (by the way, if you know - I'll appreciate if you tell me). It would be ideal for graph elements to be clickable (so that when user clicks on a block, I can handle an event with the element id specified) but I can survive even without any interactivity. Are there any components available good for this task? If no, what should I look for to help me to develop an algorithm for drawing such a graph with visually-comfortable layout?

  • Can you explain what's going on in this Ruby code?

    - by samoz
    I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code. I generally do work in C, C++, or Java, so Ruby is a pretty big change for me. I'm currently stumped with the following block of code for a database migrator: def self.up create_table :entries do |t| t.string :name t.timestamps end end Where is the t variable coming from? What does it actually represent? Is it sort of like the 'i' in a for(i=0;i<5;i++) statement? Also, where is the :entries being defined at? (entries is the name of my controller, but how does this function know about that?)

  • How to distinguish properties from constants if they both use PascalCasing for naming?

    - by Gishu
    As stated in the framework design guidelines and the WWW in general, the current guideline is to name your constants like this LastTemplateIndex as opposed to LAST_TEMPLATE_INDEX With the PascalCasing approach, how do you differentiate between a Property and a Constant. ErrorCodes.ServerDown is fine. But what about private constants within your class ? I use quite a lot of them for naming magic numbers.. or for expected values in my unit tests and so on. The ALL_CAPS style helps me know that it is a constant . _testApp.SelectTemplate(LAST_TEMPLATE_INDEX); *Disclosure: I have been using the SCREAMING_CAPS style for a while for constants + I find it more readable than squishedTogetherPascalCasedName. It actually STANDS_OUT in a block of text*

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

  • Determine cluster size of file system in Python

    - by Philip Fourie
    I would like to calculate the "size on disk" of a file in Python. Therefore I would like to determine the cluster size of the file system where the file is stored. How do I determine the cluster size in Python? Or another built-in method that calculates the "size on disk" will also work. I looked at os.path.getsize but it returns the file size in bytes, not taking the FS's block size into consideration. I am hoping that this can be done in an OS independent way...

  • How should I re-raise a Delphi exception after logging it?

    - by Nik
    Do you know a way to trap, log, and re-raise exception in Delphi code? A simple example: procedure TForm3.Button1Click(Sender: TObject); begin try raise Exception.Create('Bum'); except on E: Exception do begin MyHandleException(E); end; end; end; procedure TForm3.MyHandleException(AException: Exception); begin ShowMessage(AException.Message); LogThis(AException.Message); // raise AException; - this will access violate end; So I need to re-raise it in the except block but I was wondering if there is a better way to write my own method to handle and (on specific conditions) to re-raise exceptions.

  • Optional attribute values in MappedField

    - by David Brooks
    I'm new to Scala and Lift, coming from a slightly odd background in PLT Scheme. I've done a quick search on this topic and found lots of questions but no answers. I'm probably looking in the wrong place. I've been working my way through tutorials on using Mapper to create database-backed objects, and I've hit a stumbling block: what types should be used to stored optional attribute values. For example, a simple ToDo object might comprise a title and an optional deadline (e.g. http://rememberthemilk.com). The former would be a MappedString, but the latter could not be a MappedDateTime since the type constraints on the field require, say, defaultValue to return a Date (rather than a Date or null/false/???). Is an underlying NULL handled by the MappedField subclasses? Or are there optional equivalents to things like MappedInt, MappedString, MappedDateTime that allow the value to be NULL in the database? Or am I approaching this in the wrong way?

  • How do I handle TODO comments in VisualStudio 2010?

    - by Ivan
    I'd like Visual Studio to list all lines having "TODO: " in their beginning (usually after a comment sign which may vary depending on the file type) that can be found in any textual file in solution (may it be C#, VB, F#, T-SQL, ASPX, XAML or just TXT) in a special panel showing what's written in the line right to "TODO: ", project name (I use to contain many projects in one solution), file name, line number, code block name (like class and method) if possible. Do you know of such an extension or maybe VisualStudio has this feature built-in somewhere? For example NetBeans has a sort of out-of-the-box.

  • Using SHIFT_JIS text in PHP

    - by Joe Corkery
    I am building a form that needs to accept characters encoded in SHIFT_JIS and then send those results via email to a recipient. I've tried to simply capture the results from the $_POST variable and then to insert them into a block of text like this: $contents = <<<TEST Name: $NameJp ... TEST but that doesn't appear to work (which doesn't really surprise me). This is my first attempt at dealing with non-ASCII characters in PHP and I am hoping that people might have some suggestions. Perhaps I am missing a simple function to encode the text. Also, are there any other potential pitfalls that I might encounter? Thanks.

  • Why doesn't this list comprehension do what I expect it to do?

    - by Az
    The original list project_keys = sorted(projects.keys()) is [101, 102, 103, 104, 105, 106, 107, 108, 109, 110] where the following projects were deemed invalid this year: 108, 109, 110. Thus: for project in projects.itervalues(): # The projects dictionary is mapped to the Project class if project.invalid: # Where invalid is a Bool parameter in the Project class project_keys.remove(project.proj_id) print project_keys This will return a list of integers (which are project id's) as such: [101, 102, 103, 104, 105, 106, 107] Sweet. Now, I wanted it try the same thing using a list comprehension. project_keys = [project_keys.remove(project.proj_id) for project in projects.itervalues() if project.invalid print project_keys This returns: [None, None, None] So I'm populating a list with the same number as the removed elements but they're Nones? Can someone point out what I'm doing wrong? Additionally, why would I use a list comprehension over the for-if block at the top? Conciseness? Looks nicer?

  • Is it a solvable problem to generate a regular expression that matches some input set?

    - by Roman
    I provide some input set which contains known separated number of text blocks. I want to make a program that automatically generate 1 or more regular expressions each of which matches every text block in the input set. I see some relatively easy ways to implement a brute-force search. But I'm not an expert in compilers theory. That's why I'm curious: 1) is this problem solvable? or there are some principle impossibility to make such algorithm? 2) is it possible to achieve polynomial complexity for this algorithm and avoid brute forcing?
