• Cocoa Key event problem

  - by Oscar

  I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?

• Problem with keyPress in Mozilla

  - by sudhansu

  I am usingtextarea to get some inputs. A label shows the updated chars left. It works fine in IE, but in FF 3.0, after reaching the max limit, it doesn't allow to delete or backspace key. I am using a javascript function on keypress event of the textarea. the javascript code is function checkLength() { var opinion = document.getElementById('opinion').value; if(opinion.length > 50) alert("You have reached the mas limit."); else document.getElementById('limit').innerHTML = 50 - opinion.length; } while on the page, i am using this <label id="limit">50 </label> <textarea id="opTxtArea" onkeypress="javascript:checkLength();"></textarea> Everything is working fine. The problem arises in FF, when the inputs reach the max limit, the message is displayed, but it doesn't allow to delete or backspace.

• table cell background color change problem

  - by Mellon

  I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

• Record locking problem between linux and Windows

  - by PabloG

  I need to run a bunch of old DOS FoxPro / Clipper applications in linux under DOSEMU. The programs access their "databases" located on a network server (could be a Windows or Linux server) Actually, the programs ran fine, but I cannot manage to make the record locking work as supposed: I can run a program in two terminals (or the server and any terminal for instance) and lock the same record in both. Now, I'm using Tiny Core Linux as terminal and Windows XP as server, accesing the shared files via CIFS and the latest DOSEMU (1.4.0), but I tried with various combinations of server (Ubuntu 7 to 9, Damn Small Linux, XP) <- protocol (CIFS, samba, various versions of smbclient) <- client (same as server) with no luck I tried to configure the server part to work without oplocks in samba (after reading the entire O'Reilly Samba book locking chapter in http://oreilly.com/catalog/samba/chapter/book/ch05_05.html ) and in XP (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\UseOpportunisticLocking = 0) but the problem persist. Any ideas? TIA, Pablo

• Stringbuilder problem creating dynamic links

  - by wali

  Hi all, I'm having an issue creating a link like "<a href="javascript:window.open('www.microsoft.com');">Visit Microsoft</a> using stringbuilder. I am adding html to a panel dynamically and I am trying to create a popup link. The problem is that for some reason the link gets "mixed up". For example: Dim s As String sb.Append("<A HREF='javascript:void(0)' onclick='window.open(") sb.Append("'") sb.Append("Match.aspx?MatchID=") sb.Append(mt.MatchID) sb.Append("&batchid=") sb.Append(mb.batchID) sb.Append("')>") sb.Append("Match</A>") gives an output of : <a match.aspx?matchid="28840&amp;batchid=26596')" onclick="window.open(" href="javascript:void(0)">Match</a> I have no clue what I'm doing wrong, it even does this kind of crap for a regular string! Please help!

• Problem understanding treesort in Haskell

  - by Jerry

  I am trying to figure out how exactly does treesort from here work (I understand flatten, insert and foldr). I suppose what's being done in treesort is applying insert for each element on the list thus generating a tree and then flattening it. The only problem I can't overcome here is where the list (that is the argument of the function) is hiding (because it is not written anywhere as an argument except for the function type declaration). One more thing: since dot operator is function composition, why is it an error when I change: treesort = flatten . foldr insert Leaf to treesort = flatten( foldr insert Leaf )?

• How to solve JavaScript origin problem with an application and static file server

  - by recipriversexclusion

  In a system that I'm building I want to serve Static files (static HTML pages and a lot of images), and Dynamic XML generated by my servlet. The dynamic XML is generated from my database (through Hibernate) and I use Restlets to serve it in response to API calls. I want to create a static file server (e.g. Apache) so that this does not interfere with the dynamic server traffic. Currently both servers need to run on the same machine. I've never done something like this before and this is where I'm stuck: The static HTML pages contain JavaScript that makes API calls to the dynamic server. However, since the two servers operate on different ports, I get stuck with the same origin problem. How can this be solved? As a bonus, if you can point me to any resources that explain how to create such a static/dynamic content serving system, I'll be happy. Thanks!

• JSF and Ajax4JSF on WebSphere 6.1 --> Problem with Form Submission

  - by Shamik

  Has anyone setup JSF1.1 with Ajax4JSF on websphere 6.1 ? I followed the instructions as mentioned in the developer guide . The problem that I am facing is that once I use a4j:support on any of my h:inputText item, the form values are not getting set in the backing bean on the submission of the form. I do have <h:messages> tag present just above the form so that all the problems should be reported there but I do not see any error message once I submit the form. But I do see that the values are not getting set. I need to find the solution as early as possible otherwise I probably have to throw the ajax4jsf framework and write javascripts instead :(

• Problem setting focus to validationsummary control after validation

  - by Ed

  Hi, I have a validationsummary control which displays the summary of a few validationrequired controls and all of them belong to a validationgroup. My submit button also has the same validationgroup so it validates everything upon it being clicked. The problem i am having is setting the focus to the validationsummary control after validation occurs when my submit button is clicked. The focus goes to the top of my webform. I need the focus to be put at the validationsummary control. How do i achieve this? FYI:SetFocusOnError="true" did not work. Thanks for reading.

• Missing prop-base file problem

  - by Tony

  I am using Eclipse and SVNSubversion as a repository for a Java project. After updating the local repository and starting Eclipse, an error (in the Problems tab) appeared stating that a specific prop-base file was missing from the build path. Being inexperienced, I have accidentally deleted the prop-base file icon from the project build-path library section. Since then the numbers of errors have grown exponentially... What should I do? Updating the local repository and/or starting a new Eclipse project from the same source did not solve the problem, does anyone have an idea?

• ASP.NET Ajax partial postback and jQuery problem

  - by chromaloop

  A control contains some HTML and some jQuery to handle a fancy tooltip to display when you click an image within a div. The control is then used on several different pages, sometimes within an updatePanel, sometimes not. I have the following code to handle loading the jQuery after a partial postback when the control is displayed within an update panel. Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, args) { $('img.ormdShipping').each(function(){ $(this).qtip({ // some qtip options go here }) }); } Problem is, the jQuery doesn't load when the control is used anywhere other than an updatePanel. Do I need a second function that's triggered outside of the EndRequestHandler?

• Recompilation problem with groovlets (Groovy)

  - by BasB

  I'm new to Groovy, really like it, but found a compilation problem. I'm using Jetty as a webserver, which is serving .groovy files (groovlets) Consider two files: Test1.groovy which contains:    println new Test2().property Test2.groovy which contains:   public class Test2 {    String property = "print this"  } When calling /Test1.groovy in a browser it prints "print this". But when I change the property in something else, it still prints "print this", it won't recompile. The only thing I can do is restart jetty. Note that when all the code is in one file, recompilation does work. Is there a workaround for this..? Thanks, Bas.

• Django json serialization problem

  - by codingJoe

  I am having difficulty serializing a django object. The problem is that there are foreign keys. I want the serialization to have data from the referenced object, not just the index. For example, I would like the sponsor data field to say "sponsor.last_name, sponsor.first_name" rather than "13". How can I fix my serialization? json data: {"totalCount":"2","activities":[{"pk": 1, "model": "app.activity", "fields": {"activity_date": "2010-12-20", "description": "my activity", "sponsor": 13, "location": 1, .... model code: class Activity(models.Model): activity_date = models.DateField() description = models.CharField(max_length=200) sponsor = models.ForeignKey(Sponsor) location = models.ForeignKey(Location) class Sponsor(models.Model): last_name = models.CharField(max_length=20) first_name= models.CharField(max_length=20) specialty = models.CharField(max_length=100) class Location(models.Model): location_num = models.IntegerField(primary_key=True) location_name = models.CharField(max_length=100) def activityJSON(request): activities = Activity.objects.all() total = activities.count() activities_json = serializers.serialize("json", activities) data = "{\"totalCount\":\"%s\",\"activities\":%s}" % (total, activities_json) return HttpResponse(data, mimetype="application/json")

• Debugging over-released objects, problem with NSZombie

  - by hyn

  I have a reproduceable EXC_BAD_ACCESS during NSAutoreleasePool -drain, which seems to indicate that I am over-releasing an object. So I enable NSZombie, but then the program does not crash any more. Nor do I get any info logged to the console. If I turn NSZombie off, the crash comes back. What is the meaning of this? I thought NSZombies were used to tackle exactly this kind of problem. If NSZombie won't help, is there another way to interrogate this over-released object? Also the crash is not reproduceable on Simulator, which is why I can't use Instruments with NSZombie.
