• How to manage the default Java SwingWorker thread pool?

  - by Guy Lancaster

  I've got an application that uses 2 long-running SwingWorker tasks and I've just encountered a couple of Windows computers with updated JVMs that only start one of the them. There are no errors indicated so I have to assume that the default thread pool has only a single thread and therefore the second SwingWorker object is getting queued when I try to execute it. So, (1) how do I check check how many threads are available in the default SwingWorker thread pool, and (2) how do I add threads if I'm going to need more? Anything else that I should know? This apparent single-thread thread-pool situation goes against all of my expectations. I'm setting up a ThreadPoolExecutor but this seems so wrong...

• VS 2010 MVC Formatting

  - by Brian

  Hello, MVC is formatting my code horribly, and I was wondering if you can turn it off? I feel the answer is no, but I was hoping VS 2010 had built in a setting... Here's what its formatting as: <% if (org.UserKey.HasValue) { %> <%= org.Reference(i => i.UserReference).Email%> <% } else { %> <%= org.UserEmail%> <% } %> I want the beginning brackets on the same line as the if and the else... Thanks.

• Default Values in XForms Input

  - by Josh

  I have an XForm that has certain fields that may often be left blank (optional street address). Is there is technique to set a default value for that field, preferably a space (I am running into weird formatting issues with CSS). The html form way of value="" doesn't work, neither does setting a default value in the XML schema. EXAMPLE: <xforms:input ref="clientaddress/streetaddress2" model="model_inventory" > <xforms:label>Street Address (Line 2)</xforms:label> Leaving this field blank results in <streetaddress2/> in the resulting xml document I want <streetaddress> </streetaddress>

• Using glassfish gem with SSL

  - by Wolfgang

  My goal is to deploy a simple rails application on a windows server using the glassfish gem. I have no trouble getting the glassfish gem to work with regular http, however I now need to add SSL security and I cannot find any links on how to enable https in the glassfish gem. Has anyone succeeded in setting up the glassfish gem to support SSL? Are there any other ways to serve a rails application over SSL on windows without any additional software installation (e.g. IIS, Glassfish, jBoss)?

• Why is ContextConfiguration location different in idea and eclipse

  - by jakob

  Hello experts. In my team we work both in Eclipse and Idea. That works pretty good, except for one minor issue that I can't figure out how to solve. When setting the ContextConfiguration location in our tests and running them inside Eclipse everything works like a charm: @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:src/main/webapp/WEB-INF/applicationContext.xml" }) But in my Idea env I get "could not find applicationContext" error. I need to set the location like this(project name is services): @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:services/src/main/webapp/WEB-INF/applicationContext.xml" }) The project structure is like this: parent.pom with two child poms: services.pom and other.pom. When running the test in the terminal from the service project like this: mvn -Dtest=com.mytest.service.somepackage.TheTest test there are no issues. I guess that since my project structure is parent-with-two-children the need of /service is necessary(The project is created by pointing out the parent pom). Is there a way to fix this? Could you please help me with a solution. thx

• How do I get an unexpanded REG_EXPAND_SZ string from a remote registry?

  - by dalehhirt

  I am currently using RegistryKey.GetValue(string name, object defaultValue, RegistryValueOptions options) with RegistryValueOptions.DoNotExpandEnvironmentNames for the options value. However, this is only valid when run on the local machine. Digging down via Reflector, I find it expands the strings locally. Which means that irrespective of the setting, the strings come down remotely already expanded. Has anyone come across a solution to this that does not require running a process directly on the remote machine to get a REG_EXPAND_SZ value? Update: I attempted to use WMI's StdRegProv provider to gain access, but it still expands the strings before sending them back.

• Modern way to handle and validate POST-data in MVC 2

  - by zerkms

  There are a lot of articles devoted to working with data in MVC, and nothing about MVC 2. So my question is: what is the proper way to handle POST-query and validate it. Assume we have 2 actions. Both of them operates over the same entity, but each action has its own separated set of object properties that should be bound in automatic manner. For example: Action "A" should bind only "Name" property of object, taken from POST-request Action "B" should bind only "Date" property of object, taken from POST-request As far as I understand - we cannot use Bind attribute in this case. So - what are the best practices in MVC2 to handle POST-data and probably validate it. UPD: After Actions performed - additional logic will be applied to the objects so they become valid and ready to store in persistent layer. For action "A" - it will be setting up Date to current date.

• Do you have a development IDE hotkey set in AutoHotkey?

  - by blesh

  I've recently rejoined the AutoHotkey band wagon, and I've been setting up a master script for myself. Generally, I have a few global hotkeys, for doing things like popping open the calculator, and frequently used solutions. I even have a hotkey to restart certain local windows services, I've also got several contextual hotkeys that are only available when certain programs are active, but I don't have anything so far for my common IDE's. I generally develop in VS2008/2010 these days and they have a pretty robust shortcut and code snippet system. Still, I can't help but wonder if anyone out there has come up with a useful set of hotkeys/hotstrings in AutoHotKey for their favorite development environments? I haven't seen much out there, but I'm always interested in ways to cut back my mundane tasks with automation. Does anyone have any AutoHotkey scripts they use primarily for development?

• Subclassing UIScrollView for drawing w/o views

  - by David Dunham

  I'm contemplating subclassing UIScrollView (the way UITextView does) to draw a fairly large amount of text (formatted in ways that NSTextView can't). So far the view won't actually scroll. I'm setting contentSize, and when I drag, I see the scroll indicator. But nothing changes (and I don't get a drawRect: message). An alternate approach is to use a child view, and I've done this. The view can be over 5000 pixels high, however, and I'm a bit concerned about performance on an actual device. (The other approach, be like UITableView, would be a huge pain -- I'm "porting" Mac Cocoa code, and a collection of views would be a huge architecture change.) I've done some searching, but haven't found anyone who is using UIScrollView to do the drawing. Has anyone done this and know of any pitfalls?

• Rails, REST Architecture and HTML 5: Cross domain requests with pre-flight requests

  - by Orion

  While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request using the HTTP verb OPTIONS. In addition during testing we discovered that Firefox 3.5.8 pre-flight POST requests as well. My question is this. Is anyone aware of any project for the Rails framework working to address the issue? If not, any opinions about the best strategy to support the OPTIONS method, since it has to support the routes for all the POST, PUT, DELETE methods?

• .htaccess add hidden php get variable for language selection

  - by Eric Di Bari

  I have a multiple language website, and I use a php get variable to set the cookie for the language setting. I have multiple subfolders (http://www.site.com/es and http://www.site.com/de) that each have a respective .htaccess file. When accessing these folders, the .htaccess file does this to "silently" redirect the user and add the appropriate php variable: ------- Options +FollowSymlinks RewriteEngine on RewriteOptions MaxRedirects=10 rewriterule ^http://www.site.com/es/$ http://www.site.com/?l=es [P,R=301] rewriterule ^(.*)$ http://www.site.com/$1?l=es [P,R=301] ------- When someone accesses the root directory: http://www.site.com, I want to add a ?l=en suffix "silently" to the url. How do I do that? Thanks.

• jQuery pre document ready event

  - by Luke Duddridge

  Hi, I have a list of 179 thumbnail images that I am trying to apply a jQuery lightbox tool to an unorder list of hyper-links. The problem I have is, the jQuery isnt firing until the images have finished downloading, each image is around 23K so on their own, not so big, but as a group this equates to around 4MB. There is a delay on IE (main browser used by clients) of a good 5 seconds before the page has completely downloaded every thumbnail and then allows the jQuery to fire. I have tried putting the jQuery document ready event in various places with no success, and only been able to put a bandaid on by setting the css on the ul to hide using display:none before applying .show() after the lightbox has applied. I was hoping there is a way to make the jQuery scripts fire before all the content has downloaded? Cheers

• OpenGL Diffuse Lighting Shader Bug?

  - by anon

  The Orange book, section 16.2, lists implementing diffuse lighting as: void main() { vec3 N = normalize(gl_NormalMatrix * gl_Normal); vec4 V = gl_ModelViewMatrix * gl_vertex; vec3 L = normalize(lightPos - V.xyz); gl_FrontColor = gl_Color * vec4(max(0.0, dot(N, L)); } However, when I run this, the lighting changes when I move my camera. On the other hand, when I change vec3 N = normalize(gl_NormalMatrix * gl_Normal); to vec3 N = normalize(gl_Normal); I get diffuse lighting that works like the fixed pipeline. What is this gl_NormalMatrix, what did removing it do, ... and is this a bug in the orange book ... or am I setting up my OpenGl code improperly?

• Where to get MSDN Help Viewer for 2010 like earlier MSDN with Index, Tree and one window?

  - by Akash Kava

  I upgraded to Visual Studio 2010 RC, and I remember filling one big form for MSDN help improvement campaign and I was wondering I will get to see a Help Viewer like MSDN included in Visual Studio 2008, which included One Program (Not IE), Index and the way to view preferred language setting. Google results shows that there were headlines that Microsoft Help Viewer released for 2010 RC, but where is it? is it the same one which opens in IE and has absolute difficult way to view it? Current MSDN opening in IE is so inconvenient, there is no index, there is no grouping of content, like I typed search for TextBox and it showed up for ASP.NET, WinForms and I got lost to find out the reference in multiple pages for search results.

• Workflow foundation 4.0 message correlation and error reporting

  - by Lygpt

  I have a workflow service that runs and performs a number of different operations (such as web service calls). If one of these operations fails I call an error reporting web service to notify a seperate system that one of my workflow operations has failed. As the error could be something like the web service being down, I loop and retry this operation until it works. There can be times though when the data I'm passing to this web service is faulty and it needs changing. So I need to be able to hook into this running (but delayed) workflow and change local workflow variables and then re-run the operation. I've looked at message correlation in workflow 4.0 to achieve this but because the delay activity is active in my running workflow instance, any second service call doesn't do anything (it's like the delay activity is blocking any other requests). I've tried setting 'CanCreateInstance' to both true and false but it doesn't help. Thanks!

• Using Google AppEngine app as a OAuth provider

  - by Alistair

  Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

• Modifing settings in Django

  - by Cato Johnston

  I'm trying to get Django's manage.py to run with modified settings files. I have three settings files settings.py preview.py live.py settings.py contains my base settings but on live & preview sites I point the ['DJANGO_SETTINGS_MODULE'] to live or preview which in turn load the base file and any settings specific to that environment. This works fine, until I try to run migrations using manage.py I updated the manage.py file to import settings.preview but now when I try to run syncdb or migrate I get this error: django.core.exceptions.ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet. My settings file has this in it though: DATABASE_ENGINE = 'mysql' How can I get this to work?

• How do I read live camera data on the iPhone (like Microsoft Tag Reader)?

  - by Bill

  While the user is still in UIImagePickerController, I'd like to be able to get a UIImage representation of the image in the camera, make some changes to the image, and then display the altered image instead of the image coming directly from the camera. How can I do this? I tried setting a timer and calling takePicture, but calling it seemed to have no effect. The documentation says: Calling this method while an image is being captured has no effect. You must wait until the associated delegate object receives an imagePickerController:didFinishPickingMediaWithInfo: message before you can capture another picture. So how can I do this? I know that it's possible, since apps like Tag Reader are able to detect when something specific rolls in front of the camera. Thanks!

• Highlighting effect to text and/or image similar to be synchronized with audio

  - by Irfan Mulic

  I am looking how to approach following problem: We have application that displays text with audio recorded material. We use Browser Control (Internet Explorer) in Delphi App to do this. We respond to events in Delphi code setting innerHTML for elements if we have to update the style ... Now, request is to add option to dynamically move the cursor or dynamically highlight the words spoken from the paragraph. It doesn't need to match absolutely the exact word spoken so we will have to dynamically update the content of position of highlighted word based on some timer or something (because it is not text to speach). What should be the most practical and easy approach to this kind of problem, all answers are greatly appreciated. Thanks.

• PHP Retrieve Cookie which was not set with setcookie

  - by Martin

  I have the following problem - a third party software is setting a cookie with the login credentials and then forward the user to my app. I now need to retrieve the cookie values: The problem is - I can do this easily in the Frontend/AS3 with var ticket : String = CookieUtil.getCookie( 'ticket' ).toString(); but in PHP, the cookie is not within the $_COOKIES array. The cookie values are: Name: ticket Domain: .www.myserver.com Path : / Send for: encrypted connections only Expires: at end of session The one I see, and set before in PHP is: Name: myCookie Host: www.myserver.com Path : / Send for: any type of connection Expires: at end of session Actually, since host/domain are both the same, it should be visible in the PHP script, since it is running on this domain. Any thoughts? Thankx Martin

• Strategy in exporting to Excel with formatting from ASP.NET?

  - by Jiho Han

  So this is another exporting to Excel question. I have a page that has a table with formatting by stylesheet. When I export the page by setting the ContentType to application/excel and Content-Disposition to attachment, I can export the table to Excel (not CSV). However, it loses all formatting. I think it's because Excel does not load CSS and I guess that's reasonable. So, in a scenario where I have to show the table on the web and also export to Excel, both with similar (even if not exact) formatting, what would be the best approach without using something like NPOI? I am trying to minimize the work and keep the single template if possible. Is it necessary for me to create two separate templates: one with stylesheet, the other with embedded style in the table itself for Excel? Having a single template with conditional formatting inside would be very messy. Any ideas?

• Render tooltip on disabled HTML Button.

  - by giulio

  I have a HTML button. I have tried to render a tooltip on it based on the "title" attribute of the button and it doesn't render. Mainly because it's disabled. I then tried wrapping the button in a span and setting the "title" attribute of the span. Hovering over the button that is wrapped in the span still has no effect. The tooltip will render on any other part of the span that is not part of the button tag. Like if i put some text in the span as well as the button, hovering over the text produces the tooltip, but if you hover over the button it will not render. So: how can I display a tooltip for a disabled button?

• Visual Studio 2008 setup looking at wrong drive

• How to imitate focus on a div element?

  - by Alexis Abril

  The scenario involves imitating a drop down list. Instead of the standard input select element, we're using a set of custom images in combination with a few CSS styles and jQuery behaviors. All in all, we have a drop down list that works just fine. The question revolves around a drop down list losing focus. A normal select element losing focus would automatically close the list, however, since we are using a set of divs, it's not possibly to set or lose focus(and subsequently hide the list). We've been able to imitate normal drop down behavior by hiding a text input behind the div and setting the focus to it dynamically. For example: User clicks drop down list - content list is displayed and hidden text input is set as focus. Event is bound to the text input losing focus which hides the content list. I'm curious if the community has a better approach to hiding a div when a user clicks off, presses escape, etc.

• Panel visible=true has no effect

  I have a Panel that I'm setting visible=true explicitly. The debugger passes over that line and visible still evaluates to False on the next line. Obviously as a result, the Panel is not shown.
