  • Use of "setTimeout()" in my jQuery Expression

    - by Aaron Salazar
    I'm trying to add the JavaScript function setTimeout() to my jQuery expression. Without the setTimeout() my function loads a partial view with updated information when I enter text into my textbox. But, it loads the information with every keystroke. My logic is that if I can put in a timer then when the user stops typing, a second later the data is updated. As you can see I tried to put a setTimer() in but it doesn't seem to be working. $(function() { $('#DocId').live('keyup', function() { setTimeout(var styleValue = $(this).val(); $('#tableContent').load( '/CurReport/TableResults', { style: $(this).val()}), 1000); }), }); Thank you, Aaron

  • Setting image DPI in relation to height/width C#

    - by Aaron
    Hi, I'm writing an application to send some images to a third party, and the images must be 200x200 DPI. The image is a Bitmap and is sized at 500 width and 250 height. The first time I tested the images with the third party, my resolution was incorrect. I merely used image.SetResolution(200,200) to correctly set it to 200x200. This, however, only changed the resolution tag for the image and did not properly, according to my third party technical contact, adjust the image height and width. Is there a ratio that I can use so that for each X units I increment the resolution, I merely increment the corresponding height or width Y units? I thought that I could just increment resolution without having to increment height or width. Thank you, Aaron.

  • Groovy 1.7 changes "final"?

    - by Aaron L. Carlow
    Just started learning Groovy, got the PragProg book "Programming Groovy" and had a problem compiling one of the sample scripts: class GCar2 { final miles = 0 def getMiles() { println "getMiles called" miles } def drive(dist) { if (dist > 0) { miles += dist } } } def car = new GCar2() println "Miles: $car.miles" println 'Driving' car.drive(10) println "Miles: $car.miles" try { print 'Can I see the miles? ' car.miles = 12 } catch (groovy.lang.ReadOnlyPropertyException ex) { println ex.message GroovyCar2.groovy: 20: cannnot access final field or property outside of constructor. @ line 20, column 35. def drive(dist) { if (dist > 0) miles += dist } ^ Groovy versions prior to 1.7 do not give an error. I looked through whatever documentation I could find and did not see the issue discussed. What is going on here? Aaron

  • ldapsearch and vcard creation

    - by Aaron Hoffman
    I'm using openldap on Mac OS X Server 10.6 and need to generate a vcard for all the users in a given group. By using the ldapsearch I can list all the memberUid's for all users in that group. I found a perl script (Advanced LDAP Search or ALS) that was written by someone that will generate the vcard easily. ALS can be found here http://www.ldapman.org/tools/als.gz So what I need to do is create a wrapper script (in python or perl) that will effectively loop through the memberUid's and run the ALS command to create the vcard and append it to the file. This command provides the memberUid's: ldapsearch -x -b 'dc=ldap,dc=server,dc=com' '(cn=testgroup)' Then running ALS gives the vcard: als -b dc=ldap,dc=server,dc=com -V uid=aaronh > vcardlist.vcf If it's easier to do this using Perl since ALS is already using it that would be fine. I've done more work in python but I'm open to suggestions. Thanks in advance, Aaron

  • Issue with mysql backup in cron

    - by Aaron
    I'm just trying to perform a mysqldump and have it scheduled. I'm using RHEL 5 and have added it to the crontab as shown below: 22 13 * * * root mysqldump --user=root --password=12345 mysqldb /var/backups/mysqldbdate +%d%m.sql The .sql file never ended up in the backups folder. I even attempted to run this command line and it worked fine which tells me its something to do with the cron. Furthermore, I added a simple comand like "ls" and the output to the same directory and it worked fine. Any ideas? Thanks, Aaron

  • Find&Replace using Python - Binary file

    - by Aaron Hoffman
    Hello, I'm attempting to do a "find and replace" in a file on a Mac OS X computer. Although it appears to work correctly. It seems that the file is somehow altered. The text editor that I use (Text Wrangler) is unable to even open the file once this is completed. Here is the code as I have it: import fileinput for line in fileinput.FileInput("testfile.txt",inplace=1): line = line.replace("newhost",host) print line, When I view the file from the terminal, it does say "testfile" may be a binary file. See it anyway? Is there a chance that this replace is corrupting the file? Do I have another option for this to work? I really appreciate the help. Thank you, Aaron UPDATE: the actual file is NOT a .txt file it is a .plist file which is preference file in Mac OS X if that makes any difference

  • After .load() Reset Textbox with User Entered Value using JavaScript and jQuery

    - by Aaron Salazar
    My function below calls a partial view after a user enters a filter-by string into the text box '#DocId'. When the user is done typing, the partial view is displayed with filtered data. Since my textbox needs to be in the partial view, when user is done entering a filter-by string and is shown the filtered data, the textbox is reset and the user entered data is lost. How can I set the value of the textbox back to the user entered string after the partial view is displayed? I'm pretty sure I need to use .val() but I can't seem to get this to work. $(function() { $('#DocId').live('keyup', function() { clearTimeout($.data(this, 'timer')); var val = $(this).val(); var wait = setTimeout(function() { $('#tableContent').load('/CurReport/TableResults', { filter: val }, 500) }, 500); $(this).data('timer', wait); }); }); Thank you, Aaron

  • Jquery Fancybox not working after postback

    - by Lee Englestone
    I have a Fancybox (or more accurately) a number of fancy boxes on an asp.net page. My Fancybox (jquery plugin) works fine until a postback occurs on the page then it refuses to work. Any thoughts? Anyone experienced similar behaviour? UPDATE : Some Code.. I have a databound repeater with a fancybox on each repeating item. They are instanciated by (outside the repeater) $(document).ready(function() { $("a.watchvideo").fancybox({ 'overlayShow': false, 'frameWidth' : 480, 'frameHeight' : 400 }); }); The anchor tag is repeated.. href="#watchvideo_<%#Eval("VideoId")%" As is a div with id="watchvideo_<%#Eval("VideoId") %> As is a script element that instanciates the flash movies Yes the VideoIds are being output the the page. UPDATE : It's not a problem with the flash.. It is not a problem with the flash as i've tried it without the flash, it wont even pop a window with a simple message in. UPDATE : I wonder if it is the updatepanel. http://stackoverflow.com/questions/301473/rebinding-events-in-jquery-after-ajax-update-updatepanel -- lee

  • In Reporting Services how to filter drop down parameter list in based on other selected parameter?

    - by Lee Englestone
    Question In a Reporting Services Report, How do I filter a second drop down list of cars to only show cars whose ManufacturerId is equal the selected Manufacturer (from the first drop down list)? Report Datasets I have 2 datasets. Dataset 1. A list of Manufacturers. From a stored procedure Report_Manufacturers_P Dataset 2. A list of Cars, including a column called Manufacturers id. From a stored procedure Report_Cars_P Report Parameters On the Report I have 2 Parameters. Parameter 1. ManufacturerId. Set from A drop down list of Manufacturers (DataSet 1). Parameter 2. CarId. Set from A drop down list of Cars (DataSet 2). I've tried.. Creating another sproc called Report_Manufacturer_Cars_P that takes the ManufacturerId as an integer and returns a list of cars made by that manufacturer. Any Ideas. As selecting a Manufacturer doesn't seem to want to kick off anything that filters the Car list? Thanks in advance, -- Lee

  • Troubles Iterating Over A HashMap with JSF, MyFaces & Facelets

    - by Lee Theobald
    Hi all, I'm having some trouble looping over a HashMap to print out it's values to the screen. Could someone double check my code to see what I'm doing wrong. I can't seem to find anything wrong but there must be something. In a servlet, I am adding the following to the request: Map<String, String> facetValues = new HashMap<String, String>(); // Filling the map req.setAttribute(facetField.getName(), facetValues); In one case "facetField.getName()" evaluates to "discipline". So in my page I have the following: <ui:repeat value="${requestScope.discipline}" var="item"> <li>Item: <c:out value="${item}"/>, Key: <c:out value="${item.key}"/>, Value: <c:out value="${item.item}"/></li> </ui:repeat> The loop is ran once but all the outputs are blank?!? I would have at least expected something in item if it's gone over the loop once. Checking the debug popup for Facelets, discipline is there and on the loop. Printing it to the screen results in something that looks like a map to me (I've shortened the output) : {300=0, 1600=0, 200=0, ... , 2200=0} I've also tried with a c:forEach but I'm getting the same results. So does anyone have any ideas where I'm going wrong? Thanks for any input, Lee

  • MSBuild file for deployment process

    - by Lee Englestone
    I could do with some pointers, code examples or references that may help me do the following in an msbuild file to help speed up the deployment process.. This scenario involves getting a developers 'local' version onto a 'development' server.. Increment a developers local Web Applications Assembly version number Publish a developers local Web Application files somewhere .rar the publsihed files or folder into the format v[IncrementedAssemblyNumber].rar Copy the .rar to somewhere Backup (.rar) the existing live website folder (located elsewhere) in the format Pre_v[IncrementedAssemblyNumber].rar Move the backed up .rar to a /Backup folder. Overwrite the development web files with the published local web files Should be simple for all those MSBUILD Gurus out there. Like I said, answers or 'Good and applicable' links would be much appreciated. Also i'm thinking of getting one of the MSbuild books. From what I can tell there are 2, possibly 3 contenders. I am not using TFS. Can anyone recommend a book for beginning MSBUILD? Ideally from people that have read more than one book on the subject. Cheers, -- Lee

  • Distribute budget over for ranked components in SQL

    - by Lee
    Assume I have a budget of $10 (any integer) and I want to distribute it over records which have rank field with varying needs. Example: rank Req. Fulfilled? 1 $3 Y 2 $4 Y 3 $2 Y 4 $3 N Those ranks from 1 to 3 should be fulfilled because they are within budget. whereas, the one ranked 4 should not. I want an SQL query to solve that. Below is my initial script: CREATE TABLE budget ( id VARCHAR (32), budget INTEGER, PRIMARY KEY (id)); CREATE TABLE component ( id VARCHAR (32), rank INTEGER, req INTEGER, satisfied BOOLEAN, PRIMARY KEY (id)); INSERT INTO budget (id,budget) VALUES ('1',10); INSERT INTO component (id,rank,req) VALUES ('1',1,3); INSERT INTO component (id,rank,req) VALUES ('2',2,4); INSERT INTO component (id,rank,req) VALUES ('3',3,2); INSERT INTO component (id,rank,req) VALUES ('4',4,3); Thanks in advance for your help.

  • Really Need a Facebook App to post to Facebook Page Wall?

    - by Lee Englestone
    Hi, I'm using the Facebook API Graph (C# & ASP.NET) to try to dynamically post to a Facebook page I created. Looking at the code samples floating around.. they suggest creating a Facebook App first (which I have done).. However.. I have 3 different pages I want to post to.. Do I need to create an app for each? (I want to post different things to the 3 pages, not the same posts to each) I just want messages & links to appear as Wall posts. I'm not bothered about having an 'app' that has 'canvas' that is placed in an IFrame. Question : So do I still need to write one or more Facebook Apps to post to my 3 different Facebook pages?? Where I am so far.. I can pass in my apps credentials and get back the access_token. But my posts don't appear to be going anywhere. I'd rather drop the 'facebook application /canvas' approach if possible If I can post directly to a wall (For the above reasons). Oh, and before you ask. I don't want to post to my Apps Wall page, I want to post to my other pages (Unless I have to post to my Apps Wall page first?). I'm sure loads of people have the same questions.. Thanks in advance. -- Lee

  • How to design app to be modular / support plugins

    - by Lee
    I'm currently in the process of refactoring my webplayer so that we'll be more easily able to run it on our other internet radio stations. Much of the setup between these players will be very similar, however, some will need to have different UI plugins / other plugins. Currently in the webplayer I do something like this in it's init(): _this.ui = new UI(); _this.ui.playlist = new Playlist(); _this.ui.channelDropdown = new ChannelDropdown(); _this.ui.timecode = ne Timecode(); etc etc This works fine but that blocks me into requiring those objects at run time. What I'd like to do is be able to add those based on the stations needs. Basically my question is, do I need to add some kind of "addPlugin()" functionality here? And if I do that, do I need to constantly check from my WebPlayer object if that plugin exists before it attempts to use it? Like... if (_hasPlugin('playlist')) this.plugins.playlist.add(track); I apologize if some of this might not be clear... really trying to get my head wrapped around all of this. I feel I'm closer but I'm still stuck. Any advice on how I should proceed with this would be greatly appreciated. Thanks in advance, Lee

The “Jack Dawson” developer clings on to any new technology as the ‘next big thing’, and will find ways to shoe-horn it in to places where it is not a fit. He is very appealing to the other developers because they want to try the newest techniques and tools too, He will only stay until the new technology either bores him or becomes problematic. Jack will also be hard to find once the technology has been implemented, because he will be on to the next shiny thing. However, having a Jack Dawson on your team can be beneficial. Jack can be a great ally when attempting to convince a stodgy, corporate entity to upgrade. Jack usually has an encyclopedic recall of all the new features of the technology upgrade and is more than happy to interject them in any conversation. Tom Smykowski Tom is the neurotic employee in Office Space, and is deathly afraid of being fired. He will do only what is necessary to keep the status quo. He believes as long as nothing changes, his job is safe. He will scoff at anything new and be the naysayer during any change initiative. Tom can be useful in off-setting Jack Dawson. Jack will constantly be pushing for change and Tom will constantly be fighting it. When you see that Jack is getting kind of bored with a new technology and Tom has finally stopped wetting himself at the mere mention of it, then it is probably the sweet spot of beginning to implement that new technology (providing it is the right tool for the job). Ray Consella Ray is the guy who built the Field of Dreams. He took a risk. Sometimes he screwed it up, but he knew he didn’t want to end up regretting not attempting it. He constantly doubted himself, but he knew he had to keep going. Granted, he was doing what the voices in his head were telling him to do, but my point is he was driven to do something that most people considered crazy. Even when his friends, his wife and even he told himself he was crazy, somewhere inside himself, he knew it was the right thing to do. These are the innovators. These are the Bill Gates and Steve Jobs of the world. The take risks, they fail, they learn and the get better. Obviously, this kind of person thrives in start-ups and smaller companies, but that is due to their natural aversion to bureaucracy. They want to see their ideas put into motion quickly, and withdrawn quickly if it doesn’t work. Short feedback cycles are essential to Ray. He wants to know if his idea is working or not. He wants to modify or reverse his idea if it is not working or makes things worse. These are the agilistas. May I always be one.

  • Where I&rsquo;ve Been

    - by Lee Brandt
    Hey all. I am still here. Still kickin’. I’ve been swamped with work and community stuff. But I wanted to post about some of the things going on. Just finished up Twin Cities Code Camp 8, and had a blast! Always good to see these guys. First of all, up-coming speaking engagements: Iowa Code Camp – May 1st in Iowa City, IA [more info] DevLink – August 5-7 in Nashville, TN [more info]   Plus I am organizing a second developer’s conference in Kansas City. Kansas City Developer’s Conference (KCDC) – June 19th in Kansas City [more info]   I will also be doing Lunch & Learns for my company in April and May at JCCC: April 29th, May 12th and May 27th at Johnson County Community College in Kansas City.   So May, June and August are covered. I may just take July off, I could use a break after KCDC is over.

  • Twin Cities Code Camp 8 Retrospective

    - by Lee Brandt
    I just got back (a few hours ago) from Minneapolis, where I was speaking at the Twin Cities Code Camp 8. I’d never been to a Twin Cities Code Camp, and I have always heard such great things, so I submitted and got accepted to speak. The conference (what I got to see) was great. My talk was pretty short on people, but there are many reasons for that. First, I spoke opposite Donn Felker (speaking about developing for Android) and Keith Dahlby (speaking about Dynamic .NET). So of course, my talk is going to be empty. How could I compete with that? Plus, my talk was about software process improvement, specifically about how our process has evolved. Maybe not the smartest idea to submit to talk about software process at a developer’s conference. The people who DID attend however, seemed to really enjoy the talk. There was good interaction and good, thoughtful questions. So the attendees seemed engaged. I actually did get a chance to go to one session. I went and saw Javier Lozano talk about Open source tools for ASP.NET MVC. I am hip-deep in MVC stuff right now and getting up to speed on MVC 2 as well. I learned about MVC Turbine, Javier’s Open Source project. I will definitely be adding it to my MVC arsenal. Thanks Javier! I did forget my AC adapter for my laptop and got a little lost in Minneapolis on my way to get one from MicroCenter Saturday morning, but other than that, it was a great trip. It’s a long drive, but seeing all the guys and getting two Nut & Honey rolls from Roly Poly in Eden Prarie for lunch on Saturday made the trip totally worth it. I look forward to seeing what Jason & Chris come up with for next year! Thanks for having me guys!

  • Do NOT remove the reference to System.Core from your VS2010 Project

    - by Lee Brandt
    One of the things I routinely do when adding a new class library project, is remove all references and just add them back in as I need them. That is NOT a good idea for Visual Studio 2010. When I DID need System.Core, and went to add it back, this is what I got: "A reference to 'System.Core' could not be added. This component is automatically referenced..." After some Googling I found this article: http://connect.microsoft.com/VisualStudio/feedback/details/525663/cannot-remove-system-core-dll-reference-from-a-vs2010-project It tells you to add it back manually. Here is the part that needs back in the project file. After the last PropertyGroup node, add this node:   <ItemGroup>     <Reference Include="System.Core" />   </ItemGroup> You should be good to go again. Hope this helps.

  • WCF and Service Registry

    - by TK Lee
    I am about to build some WCF Services. Those services need to communicate to each others too, in some scenarios. I've done some "Google-ing" about Service Registry but can't figure out how to implement service registry with WCF; is there any other alternate? Is there any Microsoft technology available for Service Registry? I'm new to SOA and I will really appreciate any help or guidance (what and where should I exactly look for registry services).

  • google-chrome video application association

    - by Ben Lee
    Is there any way to tell google-chrome to launch video files of particular types in an external application (or even just to bring up the download box as if the type was un-handled), instead of showing the video inside the browser? Searching online, it seems that chrome is supposed to use xdg-mime for file associations, but apparently is ignoring this for video. For example, when I do: xdg-mime query default video/mpeg It returns dragonplayer.desktop. But when I click on a mpeg video link, chrome displays it internally instead of launching Dragon Player (if I double click on a mpeg file in my file manager, on the other hand, it does open Dragon Player). So is there a way to tell chrome to respect this setting, or another way to coax chrome into opening the file externally? If it matters, I'm running the latest version of google-chrome stable (not chromium) at the time of writing, v. 18.0.1025.151, on kubuntu 11.10.

  • Fake It Easy On Yourself

    - by Lee Brandt
    I have been using Rhino.Mocks pretty much since I started being a mockist-type tester. I have been very happy with it for the most part, but a year or so ago, I got a glimpse of some tests using Moq. I thought the little bit I saw was very compelling. For a long time, I had been using: 1: var _repository = MockRepository.GenerateMock<IRepository>(); 2: _repository.Expect(repo=>repo.SomeCall()).Return(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4:  5: ... some exercising code 6: _repository.AssertWasCalled(repo => repo.SomeCall()); I was happy with that syntax. I didn’t go looking for something else, but what I saw was: 1: var _repository = new Mock(); And I thought, “That looks really nice!” The code was very expressive and easier to read that the Rhino.Mocks syntax. I have gotten so used to the Rhino.Mocks syntax that it made complete sense to me, but to developers I was mentoring in mocking, it was sometimes to obtuse. SO I thought I would write some tests using Moq as my mocking tool. But I discovered something ugly once I got into it. The way Mocks are created makes Moq very easy to read, but that only gives you a Mock not the object itself, which is what you’ll need to pass to the exercising code. So this is what it ends up looking like: 1: var _repository = new Mock<IRepository>(); 2: _repository.SetUp(repo=>repo.SomeCall).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository.Object); 4: .. some exercizing code 5: _repository.Verify(repo => repo.SomeCall()); Two things jump out at me: 1) when I set up my mocked calls, do I set it on the Mock or the Mock’s “object”? and 2) What am I verifying on SomeCall? Just that it was called? that it is available to call? Dealing with 2 objects, a “Mock” and an “Object” made me have to consider naming conventions. Should I always call the mock _repositoryMock and the object _repository? So I went back to Rhino.Mocks. It is the most widely used framework, and show other how to use it is easier because there is one natural object to use, the _repository. Then I came across a blog post from Patrik Hägne, and that led me to a post about FakeItEasy. I went to the Google Code site and when I saw the syntax, I got very excited. Then I read the wiki page where Patrik stated why he wrote FakeItEasy, and it mirrored my own experience. So I began to play with it a bit. So far, I am sold. the syntax is VERY easy to read and the fluent interface is super discoverable. It basically looks like this: 1: var _repository = A.Fake<IRepository>(); 2: a.CallTo(repo=>repo.SomeMethod()).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4: ... some exercising code 5: A.CallTo(() => _repository.SOmeMethod()).MustHaveHappened(); Very nice. But is it mature? It’s only been around a couple of years, so will I be giving up some thing that I use a lot because it hasn’t been implemented yet? I doesn’t seem so. As I read more examples and posts from Patrik, he has some pretty complex scenarios. He even has support for VB.NET! So if you are looking for a mocking framework that looks and feels very natural, try out FakeItEasy!

  • Amazon SOA: database as a Service

    - by Martin Lee
    There is an interesting interview with Werner Vogels which is partly about how Amazon does Service Oriented Architecture: For us service orientation means encapsulating the data with the business logic that operates on the data, with the only access through a published service interface. No direct database access is allowed from outside the service, and there’s no data sharing among the services. I do not understand that. Why do they need to 'wrap' a database into some layer if it already can be consumed as a service by other service through database adaptors? Does Amazon do that just because they need to expose the database to third parties or because of anything else? Why "no direct database access is allowed"? What are the advantages of such an architectural decision?

  • WPF or WinForms for Game Development and learning resources?

    - by Stephen Lee Parker
    I'm looking to create a game framework for my own personal use... I want to use WPF, but I'm unsure if that is a wise choice... The games I will be writing should not require high performance graphics, so I am hoping to build on native classes... I do not want to rely on external DLL's unless I generate them myself. The games will be for young children, say 4 to 8. Most will be learning puzzles or simple shooters. The most advanced will be a platform game (non-scrolling screen like the old Atari Miner 2049er game). I think I know how to write something like the old Atari Chopper Command (partially written and my 4 year old loves it, but I used WinForms and GDI), Pac-Man, Tetris, Astroids, Space Invaders, Slider Puzzle, but I do not really know how to write the platform game... In my mind, I'm getting caught in collision detection and how to make a character jump and how to make a character walk up a slope or steps... Can anyone point me to information on developing a platform game in C#? Would you suggest WinForms or WPF for game development? I'm not looking for great graphics and speed, just entertaining game play...
