  • Presentation Plugin for NetBeans IDE 7.2

    - by Geertjan
    I got some excellent help from Mark Stephens, who is from IDR Solutions, which produces JPedal. Using the LGPL version of JPedal, and code provided by Mark, it's now possible to right-click the node that appears in the Presentation Window: ...after which, using a file browser (to locate a file on disk) or a URL (a very simple check is done, the URL must start with "http" and end with "pdf"), you can now open PDF files as images (thanks to conversion from PDF to images done by JPedal) into NetBeans IDE, typically (I imagine) for presentation purposes: Note that you should consider the plugin in "alpha" state. But, despite that, I've had good results. Try it and use the URL below, as a control test (since it works fine for me), which produces the result shown above: http://edu.netbeans.org/contrib/slides/netbeans-platform/presentation-4-actions.pdf  However, for some PDFs, the plugin doesn't work, and I don't know why yet (trying to figure it out with Mark), resulting in this stack trace: java.lang.ArrayIndexOutOfBoundsException: 8 at org.jpedal.objects.acroforms.formData.SwingData.completeField(Unknown Source) at org.jpedal.objects.acroforms.rendering.DefaultAcroRenderer.createField(Unknown Source) at org.jpedal.objects.acroforms.rendering.DefaultAcroRenderer.createDisplayComponentsForPage(Unknown Source) at org.jpedal.PDFtoImageConvertor.convert(Unknown Source) at org.jpedal.PdfDecoder.getPageAsImage(Unknown Source) at org.jpedal.PdfDecoder.getPageAsImage(Unknown Source) Here's the location of the plugin, install it into NetBeans IDE 7.2; feedback is very welcome: http://plugins.netbeans.org/plugin/44525

  • Marking Discussions as Answered

    As a contributor to a number of projects on CodePlex I really like the fact that the discussions feature exists but also I need ways to help me sort the discussions threads so I can make sure no-one is getting forgotten about. Seems like a lot of you agreed as the feature request Provide feature to allow Coordinators to mark Discussions threads as 'Answered' is our number 2 voted feature right now with 178 votes.  Today we rolled out the first iteration of “answer” support to discussions. In this first iteration we wanted to keep it simple and lightweight. The original poster of the thread along with project owners, developers or editors can mark any post to the thread as an answer. You can have any number of answers marked in a thread and it’s very quick to mark or unmark a post as an answer.  We deliberately keep the answers in the originally posted order so that you can see them in context with the discussion thread. When viewing discussions the default view is still to see everything, but you can easily filter by “Unanswered”.  You can even save that as a bookmark so as someone interested in the project can quickly jump to the unanswered discussion threads to go help out on. As I mention, we kept this first pass of the answering feature as simple and as lightweight as possible so that we can get some feedback on it. Head on over to the issue tracking this feature if you have any thoughts once you have used it for a bit or feel free to respond in the comments. I already have a couple of things I think we want to do such as a refresh of the look and feel of discussions in general along, make it easier to navigate to posts that are marked an answered and surface posts that you do that were marked as answered in your profile page - but if you have ideas then please let us know.

  • DataGridView CheckBox events

    - by Kevin
    I'm making a DataGridView with a series of Checkboxes in it with the same labels horizontally and vertically. Any labels that are the same, the checkboxes will be inactive, and I only want one of the two "checks" for each combination to be valid. The following screenshot shows what I have: Anything that's checked on the lower half, I want UN-checked on the upper. So if [quux, spam] (or [7, 8] for zero-based co-ordinates) is checked, I want [spam, quux] ([8, 7]) un-checked. What I have so far is the following: dgvSysGrid.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders; dgvSysGrid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells; string[] allsysNames = { "heya", "there", "lots", "of", "names", "foo", "bar", "quux", "spam", "eggs", "bacon" }; // Add a column for each entry, and a row for each entry, and mark the "diagonals" as readonly for (int i = 0; i < allsysNames.Length; i++) { dgvSysGrid.Columns.Add(new DataGridViewCheckBoxColumn(false)); dgvSysGrid.Columns[i].HeaderText = allsysNames[i]; dgvSysGrid.Rows.Add(); dgvSysGrid.Rows[i].HeaderCell.Value = allsysNames[i]; // Mark all of the "diagonals" as unable to change DataGridViewCell curDiagonal = dgvSysGrid[i, i]; curDiagonal.ReadOnly = true; curDiagonal.Style.BackColor = Color.Black; curDiagonal.Style.ForeColor = Color.Black; } // Hook up the event handler so that we can change the "corresponding" checkboxes as needed //dgvSysGrid.CurrentCellDirtyStateChanged += new EventHandler(dgvSysGrid_CurrentCellDirtyStateChanged); dgvSysGrid.CellValueChanged += new DataGridViewCellEventHandler(dgvSysGrid_CellValueChanged); } void dgvSysGrid_CellValueChanged(object sender, DataGridViewCellEventArgs e) { Point cur = new Point(e.ColumnIndex, e.RowIndex); // Change the diagonal checkbox to the opposite state DataGridViewCheckBoxCell curCell = (DataGridViewCheckBoxCell)dgvSysGrid[cur.X, cur.Y]; DataGridViewCheckBoxCell diagCell = (DataGridViewCheckBoxCell)dgvSysGrid[cur.Y, cur.X]; if ((bool)(curCell.Value) == true) { diagCell.Value = false; } else { diagCell.Value = true; } } /// <summary> /// Change the corresponding checkbox to the opposite state of the current one /// </summary> /// <param name="sender"></param> /// <param name="e"></param> void dgvSysGrid_CurrentCellDirtyStateChanged(object sender, EventArgs e) { Point cur = dgvSysGrid.CurrentCellAddress; // Change the diagonal checkbox to the opposite state DataGridViewCheckBoxCell curCell = (DataGridViewCheckBoxCell)dgvSysGrid[cur.X, cur.Y]; DataGridViewCheckBoxCell diagCell = (DataGridViewCheckBoxCell)dgvSysGrid[cur.Y, cur.X]; if ((bool)(curCell.Value) == true) { diagCell.Value = false; } else { diagCell.Value = true; } } The problem comes is that the cell value changed always seems to be "one behind" where you actually click if I use the CellValueChanged event, and I'm not sure how to get the current cell if I'm in the "dirty" state as curCell comes in as a null (suggesting the current cell address is wrong somehow, but I didn't try and get that value out) meaning that path isn't working at all. Basically, how do I get the "right" address with the right boolean value so that my flipping algorithm will work?

  • Building The Right SharePoint Team For Your Organization

    - by Mark Rackley
    I see the question posted fairly often asking what kind SharePoint team an organization should have. How many people do I need? What roles do I need to fill? What is best for my organization? Well, just like every other answer in SharePoint, the correct answer is “it depends”. Do you ever get sick of hearing that??? I know I do… So, let me give you my thoughts and opinions based upon my experience and what I’ve seen and let you come to your own conclusions. What are the possible SharePoint roles? I guess the first thing you need to understand are the different roles that exist in SharePoint (and their are LOTS). Remember, SharePoint is a massive beast and you will NOT find one person who can do it all. If you are hoping to find that person you will be sorely disappointed. For the most part this is true in SharePoint 2007 and 2010. However, generally things are improved in 2010 and easier for junior individuals to grasp. SharePoint Administrator The absolutely positively only role that you should not be without no matter the size of your organization or SharePoint deployment is a SharePoint administrator. These guys are essential to keeping things running and figuring out what’s wrong when things aren’t running well. These unsung heroes do more before 10 am than I do all day. The bad thing is, when these guys are awesome, you don’t even know they exist because everything is running so smoothly. You should definitely invest some time and money here to make sure you have some competent if not rockstar help. You need an admin who truly loves SharePoint and will go that extra mile when necessary. Let me give you a real world example of what I’m talking about: We have a rockstar admin… and I’m sure she’s sick of my throwing her name around so she’ll just have to live with remaining anonymous in this post… sorry Lori… Anyway! A couple of weeks ago our Server teams came to us and said Hi Lori, I’m finalizing the MOSS servers and doing updates that require a restart; can I restart them? Seems like a harmless request from your server team does it not? Sure, go ahead and apply the patches and reboot during our scheduled maintenance window. No problem? right? Sounded fair to me… but no…. not to our fearless SharePoint admin… I need a complete list of patches that will be applied. There is an update that is out there that will break SharePoint… KB973917 is the patch that has been shown to cause issues. What? You mean Microsoft released a patch that would actually adversely affect SharePoint? If we did NOT have a rockstar admin, our server team would have applied these patches and then when some problem occurred in SharePoint we’d have to go through the fun task of tracking down exactly what caused the issue and resolve it. How much time would that have taken? If you have a junior SharePoint admin or an admin who’s not out there staying on top of what’s going on you could have spent days tracking down something so simple as applying a patch you should not have applied. I will even go as far to say the only SharePoint rockstar you NEED in your organization is a SharePoint admin. You can always outsource really complicated development projects or bring in a rockstar contractor every now and then to make sure you aren’t way off track in other areas. For your day-to-day sanity and to keep SharePoint running smoothly, you need an awesome Admin. Some rockstars in this category are: Ben Curry, Mike Watson, Joel Oleson, Todd Klindt, Shane Young, John Ferringer, Sean McDonough, and of course Lori Gowin. SharePoint Developer Another essential role for your SharePoint deployment is a SharePoint developer. Things do start to get a little hazy here and there are many flavors of “developers”. Are you writing custom code? using SharePoint Designer? What about SharePoint Branding?  Are all of these considered developers? I would say yes. Are they interchangeable? I’d say no. Development in SharePoint is such a large beast in itself. I would say that it’s not so large that you can’t know it all well, but it is so large that there are many people who specialize in one particular category. If you are lucky enough to have someone on staff who knows it all well, you better make sure they are well taken care of because those guys are ready-made to move over to a consulting role and charge you 3 times what you are probably paying them. :) Some of the all-around rockstars are Eric Shupps, Andrew Connell (go Razorbacks), Rob Foster, Paul Schaeflein, and Todd Bleeker SharePoint Power User/No-Code Solutions Developer These SharePoint Swiss Army Knives are essential for quick wins in your organization. These people can twist the out-of-the-box functionality to make it do things you would not even imagine. Give these guys SharePoint Designer, jQuery, InfoPath, and a little time and they will create views, dashboards, and KPI’s that will blow your mind away and give your execs the “wow” they are looking for. Not only can they deliver that wow factor, but they can mashup, merge, and really help make your SharePoint application usable and deliver an overall better user experience. Before you hand off a project to your SharePoint Custom Code developer, let one of these rockstars look at it and show you what they can do (in probably less time). I would say the second most important role you can fill in your organization is one of these guys. Rockstars in this category are Christina Wheeler, Laura Rogers, Jennifer Mason, and Mark Miller SharePoint Developer – Custom Code If you want to really integrate SharePoint into your legacy systems, or really twist it and make it bend to your will, you are going to have to open up Visual Studio and write some custom code.  Remember, SharePoint is essentially just a big, huge, ginormous .NET application, so you CAN write code to make it do ANYTHING, but do you really want to spend the time and effort to do so? At some point with every other form of SharePoint development you are going to run into SOME limitation (SPD Workflows is the big one that comes to mind). If you truly want to knock down all the walls then custom development is the way to go. PLEASE keep in mind when you are looking for a custom code developer that a .NET developer does NOT equal a SharePoint developer. Just SOME of the things these guys write are: Custom Workflows Custom Web Parts Web Service functionality Import data from legacy systems Export data to legacy systems Custom Actions Event Receivers Service Applications (2010) These guys are also the ones generally responsible for packaging everything up into solution packages (you are doing that, right?). Rockstars in this category are Phil Wicklund, Christina Wheeler, Geoff Varosky, and Brian Jackett. SharePoint Branding “But it LOOKS like SharePoint!” Somebody call the WAAAAAAAAAAAAHMbulance…   Themes, Master Pages, Page Layouts, Zones, and over 2000 styles in CSS.. these guys not only have to be comfortable with all of SharePoint’s quirks and pain points when branding, but they have to know it TWICE for publishing and non-publishing sites.  Not only that, but these guys really need to have an eye for graphic design and be able to translate the ramblings of business into something visually stunning. They also have to be comfortable with XSLT, XML, and be able to hand off what they do to your custom developers for them to package as solutions (which you are doing, right?). These rockstars include Heater Waterman, Cathy Dew, and Marcy Kellar SharePoint Architect SharePoint Architects are generally SharePoint Admins or Developers who have moved into more of a BA role? Is that fair to say? These guys really have a grasp and understanding for what SharePoint IS and what it can do. These guys help you structure your farms to meet your needs and help you design your applications the correct way. It’s always a good idea to bring in a rockstar SharePoint Architect to do a sanity check and make sure you aren’t doing anything stupid.  Most organizations probably do not have a rockstar architect on staff. These guys are generally brought in at the deployment of a farm, upgrade of a farm, or for large development projects. I personally also find architects very useful for sitting down with the business to translate their needs into what SharePoint can do. A good architect will be able to pick out what can be done out-of-the-box and what has to be custom built and hand those requirements to the development Staff. Architects can generally fill in as an admin or a developer when needed. Some rockstar architects are Rick Taylor, Dan Usher, Bill English, Spence Harbar, Neil Hodgkins, Eric Harlan, and Bjørn Furuknap. Other Roles / Specialties On top of all these other roles you also get these people who specialize in things like Reporting, BDC (BCS in 2010), Search, Performance, Security, Project Management, etc... etc... etc... Again, most organizations will not have one of these gurus on staff, they’ll just pay out the nose for them when they need them. :) SharePoint End User Everyone else in your organization that touches SharePoint falls into this category. What they actually DO in SharePoint is determined by your governance and what permissions you give these guys. Hopefully you have these guys on a fairly short leash and are NOT giving them access to tools like SharePoint Designer. Sadly end users are the ones who truly make your deployment a success by using it, but are also your biggest enemy in breaking it.  :)  We love you guys… really!!! Okay, all that’s fine and dandy, but what should MY SharePoint team look like? It depends! Okay… Are you just doing out of the box team sites with no custom development? Then you are probably fine with a great Admin team and a great No-Code Solution Development team. How many people do you need? Depends on how busy you can keep them. Sorry, can’t answer the question about numbers without knowing your specific needs. I can just tell you who you MIGHT need and what they will do for you. I’ll leave you with what my ideal SharePoint Team would look like for a particular scenario: Farm / Organization Structure Dev, QA, and 2 Production Farms. 5000 – 10000 Users Custom Development and Integration with legacy systems Team Sites, My Sites, Intranet, Document libraries and overall company collaboration Team Rockstar SharePoint Administrator 2-3 junior SharePoint Administrators SharePoint Architect / Lead Developer 2 Power User / No-Code Solution Developers 2-3 Custom Code developers Branding expert With a team of that size and skill set, they should be able to keep a substantial SharePoint deployment running smoothly and meet your business needs. This does NOT mean that you would not need to bring in contract help from time to time when you need an uber specialist in one area. Also, this team assumes there will be ongoing development for the life of your SharePoint farm. If you are just going to be doing sporadic custom development, it might make sense to partner with an awesome firm that specializes in that sort of work (I can give you the name of a couple if you are interested).  Again though, the size of your team depends on the number of requests you are receiving and how much active deployment you are doing. So, don’t bring in a team that looks like this and then yell at me because they are sitting around with nothing to do or are so overwhelmed that nothing is getting done. I do URGE you to take the proper time to asses your needs and determine what team is BEST for your organization. Also, PLEASE PLEASE PLEASE do not skimp on the talent. When it comes to SharePoint you really do get what you pay for when it comes to employees, contractors, and software.  SharePoint can become absolutely critical to your business and because you skimped on hiring a developer he created a web part that brings down the farm because he doesn’t know what he’s doing, or you hire an admin who thinks it’s fine to stick everything in the same Content Database and then can’t figure out why people are complaining. SharePoint can be an enormous blessing to an organization or it’s biggest curse. Spend the time and money to do it right, or be prepared to spending even more time and money later to fix it.

  • How should I plan the inheritance structure for my game?

    - by Eric Thoma
    I am trying to write a platform shooter in C++ with a really good class structure for robustness. The game itself is secondary; it is the learning process of writing it that is primary. I am implementing an inheritance tree for all of the objects in my game, but I find myself unsure on some decisions. One specific issue that it bugging me is this: I have an Actor that is simply defined as anything in the game world. Under Actor is Character. Both of these classes are abstract. Under Character is the Philosopher, who is the main character that the user commands. Also under Character is NPC, which uses an AI module with stock routines for friendly, enemy and (maybe) neutral alignments. So under NPC I want to have three subclasses: FriendlyNPC, EnemyNPC and NeutralNPC. These classes are not abstract, and will often be subclassed in order to make different types of NPC's, like Engineer, Scientist and the most evil Programmer. Still, if I want to implement a generic NPC named Kevin, it would nice to be able to put him in without making a new class for him. I could just instantiate a FriendlyNPC and pass some values for the AI machine and for the dialogue; that would be ideal. But what if Kevin is the one benevolent Programmer in the whole world? Now we must make a class for him (but what should it be called?). Now we have a character that should inherit from Programmer (as Kevin has all the same abilities but just uses the friendly AI functions) but also should inherit from FriendlyNPC. Programmer and FriendlyNPC branched away from each other on the inheritance tree, so inheriting from both of them would have conflicts, because some of the same functions have been implemented in different ways on the two of them. 1) Is there a better way to order these classes to avoid these conflicts? Having three subclasses; Friendly, Enemy and Neutral; from each type of NPC; Engineer, Scientist, and Programmer; would amount to a huge number of classes. I would share specific implementation details, but I am writing the game slowly, piece by piece, and so I haven't implemented past Character yet. 2) Is there a place where I can learn these programming paradigms? I am already trying to take advantage of some good design patterns, like MVC architecture and Mediator objects. The whole point of this project is to write something in good style. It is difficult to tell what should become a subclass and what should become a state (i.e. Friendly boolean v. Friendly class). Having many states slows down code with if statements and makes classes long and unwieldy. On the other hand, having a class for everything isn't practical. 3) Are there good rules of thumb or resources to learn more about this? 4) Finally, where does templating come in to this? How should I coordinate templates into my class structure? I have never actually taken advantage of templating honestly, but I hear that it increases modularity, which means good code.

  • How to use Sprockets Rails plugin on Heroku?

    - by Kevin
    Hi, I just deployed my Rails app to Heroku, but the Javascripts that were using Sprockets plugin don't work. I understood that, because my Heroku app is read-only, Sprockets won't work. I've found this sprockets_on_heroku plugin that should do the work, but I don't really get how to use it : I added config.gem sprockets in config/environment.rb I added sprockets in my .gems file I pushed these on Heroku and Sprockets was successfully installed I locally ran script/plugin install git://github.com/jeffrydegrande/sprockets_on_heroku.git and the plugin was successfully installed Nothing changed on Heroku, so I tried to install the plugin on Heroku with heroku plugins:install git://github.com/jeffrydegrande/sprockets_on_heroku.git, which returned sprockets_on_heroku installedbut then, a heroku restartor a heroku pluginscommand would return this: ~/.heroku/plugins/sprockets_on_heroku/init.rb:1: uninitialized constant ActionController (NameError) from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/../lib/heroku/plugin.rb:25:in `load' from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/../lib/heroku/plugin.rb:25:in `load!' from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/../lib/heroku/plugin.rb:22:in `each' from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/../lib/heroku/plugin.rb:22:in `load!' from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/../lib/heroku/command.rb:14:in `run' from /opt/local/lib/ruby/gems/1.8/gems/heroku-1.8.3/bin/heroku:14 from /opt/local/bin/heroku:19:in `load' from /opt/local/bin/heroku:19 What should I do?

  • .NET COM Interop on Windows 7 64Bit gives me a headache

    - by Kevin Stumpf
    Hey guys, .NET COM interop so far always has been working quite nicely. Since I upgraded to Windows 7 I don't get my .NET COM objects to work anymore. My COM object is as easy as: namespace Crap { [ComVisible(true)] [Guid("2134685b-6e22-49ef-a046-74e187ed0d21")] [ClassInterface(ClassInterfaceType.None)] public class MyClass : IMyClass { public MyClass() {} public void Test() { MessageBox.Show("Finally got in here."); } } } namespace Crap { [Guid("1234685b-6e22-49ef-a046-74e187ed0d21")] public interface IMyClass { } } assembly is marked ComVisible as well. I register the assembly using regasm /codebase /tlb "path" registers successfully (admin mode). I tried regasm 32 and 64bit. Both time I get the error "ActiveX component cant create object Crap.MyClass" using this vbscript: dim objReg Set objReg = CreateObject("Crap.MyClass") MsgBox typename(objReg) fuslogvw doesn't give me any hints either. That COM object works perfectly on my Vista 32 Bit machine. I don't understand why I haven't been able to google a solution for that problem.. am I really the only person that ever got into that problem? Looking at OleView I see my object is registered successfully. I am able to create other COM objects as well.. it only does not work with my own ones. Thank you, Kevin

  • Intern working for Indian NGO - Help with PHP 4, advising staff

    - by Kevin Burke
    Hello, For the past three months I've been working for an Indian NGO (http://sevamandir.org), doing some volunteer work in the field but also trying to improve their website, which needs a ton of work. Recently I've been trying to fix the "subscribe to newsletter" button, which is broken. I used filter_var to filter the email input, but when I tried to test this out I got an error. Then I learned that the web host is still using php version 4.3.2 and register_globals is turned on. I've mentioned that they should upgrade their web host before (they are paying around $50 per year for Rediff Web Hosting, complete with 100MB storage and 1 MySQL database). That would add a lot of complexity for the IT staff of 3, who would have to update everyone's email information (I assume? this is a 250-person organization), and have me find a new web host and teach them about it. The staff isn't that sophisticated about web usage - the head guy still uses IE6, and the website's laid out in tables (they use Dreamweaver WYSIWYG to lay out pages). So I've got two options - use regular expressions to filter the email, which I'm not that skilled at doing (and would be more vulnerable to exploitation after I leave), turn off register globals and then try to teach the staff what I'm doing, or try to get them to upgrade their versions of PHP and MySQL and/or change web host. I'd appreciate some advice. Thanks for your help, Kevin

  • BackgroundWorker From ASP.Net Application

    - by Kevin
    We have an ASP.Net application that provides administrators to work with and perform operations on large sets of records. For example, we have a "Polish Data" task that an administrator can perform to clean up data for a record (e.g. reformat phone numbers, social security numbers, etc.) When performed on a small number of records, the task completes relatively quickly. However, when a user performs the task on a larger set of records, the task may take several minutes or longer to complete. So, we want to implement these kinds of tasks using some kind of asynchronous pattern. For example, we want to be able to launch the task, and then use AJAX polling to provide a progress bar and status information. I have been looking into using the BackgroundWorker class, but I have read some things online that make me pause. I would love to get some additional advice on this. For example, I understand that the BackgroundWorker will actually use the thread pool from the current application. In my case, the application is an ASP.Net web site. I have read that this can be a problem because when the application recycles, the background workers will be terminated. Some of the jobs I mentioned above may take 3 minutes, but others may take a few hours. Also, we may have several hundred administrators all performing similar operations during the day. Will the ASP.Net application thread pool be able to handle all of these background jobs efficiently while still performing it's normal request processing? So, I am trying to determine if using the BackgroundWorker class and approach is right for our needs. Should I be looking at an alternative approach? Thanks and sorry for such a long post! Kevin

  • Pass a data.frame column name to a function

    - by Kevin Middleton
    I'm trying to write a function to accept a data.frame (x) and a column from it. The function performs some calculations on x and later returns another data.frame. I'm stuck on the best-practices method to pass the column name to the function. The two minimal examples fun1 and fun2 below produce the desired result, being able to perform operations on x$column, using max() as an example. However, both rely on the seemingly (at least to me) inelegant (1) call to substitute() and possibly eval() and (2) the need to pass the column name as a character vector. fun1 <- function(x, column){ do.call("max", list(substitute(x[a], list(a = column)))) } fun2 <- function(x, column){ max(eval((substitute(x[a], list(a = column))))) } df <- data.frame(A = 1:20, B = rnorm(10)) fun1(df, "B") fun2(df, "B") I would like to be able to call the function as fun(df, B), for example. Other options I have considered but have not tried: Pass column as an integer of the column number. I think this would avoid substitute(). Ideally, the function could accept either. with(x, get(column)), but, even if it works, I think this would still require substitute Make use of formula() and match.call(), neither of which I have much experience with. Subquestion: Is do.call() preferred over eval()? Thanks, Kevin

  • Sanitizing user input that will later be e-mailed - what should I be worried about?

    - by Kevin Burke
    I'm interning for an NGO in India (Seva Mandir, http://sevamandir.org) and trying to fix their broken "subscribe to newsletter" box. Because the staff isn't very sophisticated and our web host isn't great, I decided to send the relevant data to the publications person via mail() instead of storing it in a MySQL database. I know that it's best to treat user input as malicious, and I've searched the SO forums for posts relevant to escaping user data for sending in a mail message. I know the data should be escaped; what should I be worried about and what's the best way to sanitize the input before emailing it? Form flow: 1. User enters email on homepage and clicks Submit 2. User enters name, address, more information on second page (bad usability, I know, but my boss asked me to) and clicks "Submit" 3. Collect the data via $_POST and email it to the publications editor (and possibly send a confirmation to the subscriber). I am going to sanitize the email in step 2 and the other data in step 3. I appreciate your help, Kevin

  • How to :update after :success with link_to_remote Rails method?

    - by Kevin
    Hi, I'm trying to get two things done after a user clicks on a link: Delete a div Add another element at the bottom of the page I played with Rails link_to_remote and what I get with the code below is that the element is added before the div is deleted: <%= link_to_remote "&#x2713;", :url => { :controller => :movies, :action => :mark_as_seen, :movie => movie, :render => 'movie' }, :success => "Effect.Fade('movie_#{movie.id}_wrapper', { duration: 0.4 })", :update => "movies", :position => "bottom", :failure => "alert('Ooops! An error occurred.')" %> I tried to put :update and :position in a :complete callback, but nothing happened. And when I put both of them in the :success callback (after Effect.Fade), all I get is a parsing error. Any idea? Thanks, Kevin

  • SSH connection times out

    - by mark
    Given: vm - a WinXPsp3 virtual machine hosted by a Win7sp1 physical machine alice is the user on vm srv - a Win2008R2sp1 server bob is the user on srv quake - a linux server mark is the user on quake Both vm and srv have the same new installation of cygwin (1.7.9) and openssh. Firewall service is disabled on vm (and its host) and on srv All the machines can be pinged from all the machines. ssh mark@quake works OK from both vm and srv. ssh bob@srv works OK from both quake and vm. ssh alice@vm works on the vm itself only, but it fails on the other two machines: alice@vm ~ $ ssh alice@vm alice@vm's password: Last login: Tue Oct 25 23:42:09 2011 from vm.shunra.net [mark@Quake ~]$ ssh -vvv alice@vm OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out bob@Srv ~ $ ssh -vvv alice@vm OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out I used ssh-host-config both on vm and srv to configure the ssh to run as a windows service. Besides that I did nothing else. Can anyone help me troubleshoot this issue? Thank you very much. EDIT The virtual machine software is VMWare Workstation 7.1.4. I think the problem is in its settings, but I have no idea where exactly. The Network Adapter is set to Bridged. EDIT2 All the machines are located in the company lab, I think all of them are on the same segment, but I may be wrong. Below is the ipconfig /all output for each machine (skipping the linux server). I have deleted the Tunnel adapters to keep the output minimal. If anyone thinks they matter, do tell so and I will post them as well. In addition ping output is given to show that DNS is correct. Something else, may be relevant, may be not.

  • Silverlight 4 Default Button Service

    - by Mark Cooper
    For a few months I have been successfully using David Justices Default Button example in my SL 3 app. This approach is based on an attached property. After upgrading to SL4, the approach no longer works, and I get a XAML exception: "Unknown parser error: Scanner 2148474880" Has anyone succesfully used this (or any other) default button attached behaviours in SL4? Is there any other way to achieve default button behaviour in SL4 with the new classes that are available? Thanks, Mark

  • Julian day of the year in Java

    - by Mark
    I have seen the "solution" at http://www.rgagnon.com/javadetails/java-0506.html, but it doesn't work correctly. E.g. yesterday (June 8) should have been 159, but it said it was 245. So, does someone have a solution in Java for getting the current date's three digit Julian day (not Julian date - I need the day this year)? Thanks! Mark

  • Convert UTC DateTime to another Time Zone

    - by Mark Richman
    I have a UTC DateTime value coming from a database record. I also have a user-specified time zone (an instance of TimeZoneInfo). How do I convert that UTC DateTime to the user's local time zone? Also, how do I determine if the user-specified time zone is currently observing DST? I'm using .NET 3.5. Thanks, Mark

  • Can I have a macro run whenever I save a file in Visual Studio 2005?

    - by Mark
    When I save a file in Visual Studio 2005, I'd like to have a macro also run that updates a copyright (through a regular expression search and replace). I'm not new to regular expressions, but I am new to VB/VBA and Visual Studio macros, so what I need help with specifically is: getting a macro to run upon save, preferably after I press CTRL-S but before it actually writes the file so that the results of the search and replace are actually saved without having to save twice calling search and replace for a regular expression from inside the VB/VBA macro Thanks, Mark

  • How to calculate next Friday at 3am?

    - by Mark
    How can you calculate the following Friday at 3am as a datetime object? Clarification: i.e., the calculated date should always be greater than 7 days away, and less than or equal to 14. Going with a slightly modified version of Mark's solution: def next_weekday(dt=datetime.datetime.now(), time_of_day=datetime.time(hour=3), day_of_week=4): dt += datetime.timedelta(days=7) if dt.time() < time_of_day: dt = dt.combine(dt.date(), time_of_day) else: dt = dt.combine(dt.date(), time_of_day) + datetime.timedelta(days=1) return dt + datetime.timedelta((day_of_week - dt.weekday()) % 7)

  • Can I have a macro in Visual Studio 2005 call a DOS command and redirect the output to a file?

    - by Mark
    I'd like to have a macro in Visual Studio 2005 that calls a DOS command and redirects the output (stdout and stderr) to a file. Just calling the command and "" redirecting it will not capture stderr, so there are two parts to this: calling a DOS command capturing both stderr and stdout to a file during that call I'd then like to open this file in Visual Studio after the command completes. I'm new to Visual Studio 2005 macro writing, and VB/VBA, so that's the kind of help that I'm looking for. Thanks, Mark

    Hi I've recently installed VS2010 and I'm trying to upgrade a project that I created using VS2008 and WSSF (Web Service Software Factory). I've installed the 2010 version of WSSF and it's prerequisites. After upgrading, when I try to load the solution I get "blah.ssfproduct cannot be opened because its project type (.ssfproduct) is not supported by this version of the application". Absolutely no idea what to do :( Cheers Mark

  • Define a varbinary(max) column using sqlalchemy on MS SQL Server

    Hi, I'm querying an SQL Server database using SQLAlchemy and need to cast a column to varbinary(max). The thing I am struggling with is the "max" part. I can get the cast to work for any actual number (say varbinary(20)), but I cannot find how to get it to work for the "max" size of the varbinary column. Any pointers? Links? Solutions?

  • Silverlight DataGrid Updating SelectedItem from code

    When I update a datagrid SelectedItem from code (via a bound object in a ViewModel), how to I get the visual grid to highlight the newly selected item? Thanks, Mark UPDATE: This is still an issue for me. My SelectedItem property already implements change notification, but the datagrid is not VISUALLY displaying which row has been selected - i.e. it is not getting highlighted.
