• telerik mvc grid access cell data to enable columns.Command

  - by AZee

  Hi! I can't seem to find a way to reference the value in a column in the grid, in my case it is the StatusId. Based on the cell value in this row, for the StatusId, I need to return a true or false to the method ".Visible(???)". It would be nice to find the answer in the documentation online but I haven't been able to. I find it hard to believe that I would be the first person who ever needed this functionality. I would be most appreciative of any assistance since no one in the telerik forums know. .Columns(columns => { columns.Command(commands => { commands.Edit().ButtonType(ButtonType); commands.Delete().ButtonType(ButtonType); }).Width(90).Visible(???); Thanks!

• How to get users to read error messages?

  - by FX

  If you program for a nontechnical audience, you find yourself at a high risk that users will not read your carefully worded and enlightening error messages, but just click on the first button available with a shrug of frustration. So, I'm wondering what good practices you can recommend to help users actually read your error message, instead of simply waiving it aside. Ideas I can think of would fall along the lines of: Formatting of course help; maybe a simple, short message, with a "learn more" button that leads to the longer, more detailed error message Have all error messages link to some section of the user guide (somewhat difficult to achieve) Just don't issue error messages, simply refuse to perform the task (a somewhat "Apple" way of handling user input) Edit: the audience I have in mind is a rather broad user base that doesn't use the software too often and is not captive (i.e., not an in-house software or narrow community). A more generic form of this question was asked on slashdot, so you may want to check there for some of the answers.

• Trying to extend ActionView::Helpers::FormBuilder

  - by nibbo

  Hello I am trying to DRY up some code by moving some logic into the FormBuilder. After reading the documentation about how to select and alternative form builder the logical solution for me seemed to be something like this. In the view <% form_for @event, :builder => TestFormBuilder do |f| %> <%= f.test %> <%= f.submit 'Update' %> <% end %> and then in app/helpers/application_helper.rb module ApplicationHelper class TestFormBuilder < ActionView::Helpers::FormBuilder def test puts 'apa' end end end This, however, gives me an error at the "form_for" uninitialized constant ActionView::Base::CompiledTemplates::TestFormBuilder Where am I doing it wrong?

• Ruby on Rails 2.3.5: update_all failing on ActiveRecord

  - by randombits

  I'm trying to update a collection of records in my database using ActiveRecord's update_all. Enter script/console. MyModel.update_all("reserved = 1", :order => 'rand()', :limit => 1000) ActiveRecord thinks order is a column, says it's unknown and throws an exception. According to the documentation though, my syntax looks sane. This is RoR 2.3.5. When doing MyModel.update_all("reserved = 1") alone, it works just fine. Also if I do MyModel.update_all("reserved = 1", "reserve_type = 2", :order = "rand()", :limit = 1000) = 0 0 rows affected. I'm simply trying to do: UPDATE MyModel SET reserved=1, reserve_type=2 ORDER BY RAND() LIMIT 1000

  I need help creating a LINQ SQL with subsonic.

• Get Contact Profile Information from Office Communicator (OCS) SDK in C#?

  - by Andrew

  Hi, My company uses MS Office Communicator Server (OCS) 2007 R2, and I am accessing with C# with the SDK. If I right click on a contact in OCS, I get the option to 'View Contact Card'. I want access to this via the API! Unfortunately I can find nothing in the SDK documentation to get at this. There is a method called 'ViewProfile' which is unsupported, and I can find nothing out there about it. I could of course go directly to the Active Directory account of the contact, but that would require my machine to connect to the organization via VPN. Since most of us work 'offline' I would prefer not to do this. (The data I need is anyway in OCS!) Thanks in advance, Andrew

• What is the worst C#/.NET gotcha?

  - by MusiGenesis

  This question is similar to this one, but focused on C# and .NET. I was recently working with a DateTime object, and wrote something like this: DateTime dt = DateTime.Now; dt.AddDays(1); return dt; // still today's date! WTF? The intellisense documentation for AddDays says it adds a day to the date, which it doesn't - it actually returns a date with a day added to it, so you have to write it like: DateTime dt = DateTime.Now; dt = dt.AddDays(1); return dt; // tomorrow's date This one has bitten me a number of times before, so I thought it would be useful to catalog the worst C# gotchas.

• Review Board workflow for Mercurial repository

  - by pachanga

  At my company we are trying to add code reviewing practices into our development process and for that purpose we decided to use Review Board. While Review Board should work out of the box for Subversion the workflow for Mercurial looks a little bit involved. Firstly it seems that only post reviewing(via post-review script) is supported for this type of repo. Secondly documentation is unclear whether post-review actually supports Mercurial(it only mentions git). Could you folks describe your workflow in detail please? Am I right in my thinking it should be something like this: Developer: clone master repo clone feature repo from local master repo hack-hack in feature repo commit into feature repo somehow run post-review from feature repo against parent master repo Reviewer: review diff if OK then pull to the master repo from the feature repo

• Spring security annotations with EL -- requires debug information compiled in?

  - by HDave

  I am considering using Spring Security annotations for my application, with the EL (expression language) feature. For example: @PreAuthorize("hasPermission(#contact, 'admin')") public void deletePermission(Contact contact, Sid recipient, Permission permission); I need the EL capability because I have built my own ACL implementation. However, to use this capability with the "#contact" type arguments, the Spring documentation says this: You can access any of the method arguments by name as expression variables, provided your code has debug information compiled in. This begs two questions: It is acceptable to have a production application commercially distributed with debug info in it? If not, is there any way around this? Thanks for any guidance on this!

  The Document class have a getDoctype method but doesn't have a setDoctype. The documentation says: The DOM Level 2 does not support editing the Document Type Declaration. docType cannot be altered in any way, including through the use of methods inherited from the Node interface, such as insertNode or removeNode. and in my project I need to generate xml files with my specified doctypes. I've tryied to create my own DefaultNode, but it throws "DOMException: Method not supported" for the setters. Any idea?

• Invalid Argument IE 8 jQuery

  - by Deshiknaves

  Hi, I have this particular script that runs so that the flash elements don't show up on top of my slide out navigation. This redraws that flash element with wmode as opaque and so it shows up under the navigation. Works perfectly with Chrome and FireFox but not with IE. In IE I get an Invalid Argument in jquery.min.js code 0 Line 103 char 460. Can anyone help me as to why? If I comment out the second line of code inside the function then there is no error, but then doesn't work in FireFox. Any help is appriciated. $(window).load(function(){ $('embed').attr('wmode','opaque'); $('object').append('<param name="wmode" value="opaque">'); $('object').wrap('<div>'); });

• Exporting tasks to 'C using DPI

  I have an verilog based test-bench, interfaced to 'C source using DPI. Now using DPI I am planning to write my whole firmware. To do this I need 3 things Register Read Register Write Interrupt handler As I understand, register reads and writes are tasks that I need to export from the RTL test-bench. And Interrupt handler (I implemented by importing a function from 'C). I checked most the cadence documentation and found no useful hints. I have also registered with cadence users community but it seems that I cannot ask question till they approve my registration. Just in case someone is aware of this, would appreciate their help.

Things like better authentication for example and making better logins. You can post any suggestion, but just for your information, I mainly code my web apps with Javascript and PHP. Also, I transfer my data using JSON or XML. Thanks a lot

• How to read in text from the visual studio debug output window

  - by Jeremy Bell

  I've read several articles that tell you how to add text to the output window in visual studio from within an Add-On (specifically, a visual studio 2008 integration package, via the visual studio 2008 SDK 1.1), but no examples of how to read text from the output window. My goal is to parse text from the debug output window while debugging a certain application (TRACE output and possibly stdin/stdout). The IVsOutputWindowPane interface has no methods for reading in text from the output window. The documentation seems to imply that it is possible, but it doesn't provide an example: http://msdn.microsoft.com/en-us/library/bb166236(VS.80).aspx Quote: In addition, the OutputWindow and OutputWindowPane objects add some higher-level functionality to make it easier to enumerate the Output window panes and to retrieve text from the panes. Preferably I'd like to be able to subscribe to an event that fires when a new line of text arrives, similar to a StreamReader's asynchronous reads.

• How do I setup FitNesse for use with .NET?

  - by Fredrik

  I'm trying to get started with FitNesse for .NET on Windows Vista. In all tutorials I find on the web I'm told to execute the run.bat file, but all i get when downloading the latest release is a .jar-file. When i run this, the filestructure is unpacked and I can reach the fitnesse server by browsing to http://localhost. Now, when I'm trying to set up a test project, according to all documentation I find I'm supposed define the path to fitsharp.dll but I can't find this file anywhere in the filestructure that was set up from the .jar-file. What am I doing wrong? Sincerely, Fredrik

• Specific checkboxes checked in symfony 1.4

  - by Tom

  Hi, I'm able to do the following for all checkboxes in a set (in an action): $this->form->getWidget('some_form_field')->setAttribute('checked', 'checked'); ... but I'm unable to set specific checkboxes to ticked on the basis of data returned from the db. I'm after something like: $this->form->getWidget('some_form_field')->setAttributes(array(....)); ... where I can refer to the specific checkboxes to be ticked somehow, or pass an array to it. There's nothing in the symfony documentation on this specifically and I've had enough of trying a dozen combinations to get it work. Any help would be appreciated. Thanks.

• Jruby embedded modules and classes.

  - by James Moore

  Hey, I have a ruby file as follows: module Example class Myclass def t_st "Hello World!" end end end now if this was just a class I would be able to use the following java code: ScriptEngine jruby = new ScriptEngineManager().getEngineByName("jruby"); jruby.eval(new BufferedReader(new FileReader("example.rb"))); Object example = jruby.eval("myclass.new"); However, this class rests inside a module. Calling the same code as above produces the error: Exception in thread "main" org.jruby.embed.EvalFailedException: uninitialized constant myclass In addition, calling: Object example = jruby.eval("Example"); The module returns no error. So one would assume this follows the format for Ruby. Object example = jruby.eval("Example::myclass.new"); Again however, I get the same error as before. Can anyone help? As there is little documentation on JRuby? Thanks

• wowza vs Flash Media Server (FMS / FMIS) - ease of integration with ASP.Net

  - by alchemical

  We're creating a web site offering one to many video chat and trying to decide on which of these streaming servers to go with. Looking at around 256kbps live streams, hoping to achieve at least 1000 simultaneous streams on one 8-core server. Wowza is cheaper (1k vs 5k for FMS), and appears to be used successfully by many sites (StreamLive, Justin.TV, etc.). However, some people have expressed that it may be more difficult to work with. I.e. fine-tuning it, less documentation, integration with ASP.Net code, etc. Wondering if anyone with real-world experience with either of these servers can advise regarding how easy or difficult to use and integrate they are for a site like this. Also wondering if there is any performance difference (lag, etc.).

• Problem reading from the StandarOutput from ftp.exe. Possible System.Diagnostics.Process Framework b

  - by SoMoS

  Hello, I was trying some stuff executing console applications when I found this problem handling the I/O of the ftp.exe command that everybody has into the computer. Just try this code: m_process = New Diagnostics.Process() m_process.StartInfo.FileName = "ftp.exe" m_process.StartInfo.CreateNoWindow = True m_process.StartInfo.RedirectStandardInput = True m_process.StartInfo.RedirectStandardOutput = True m_process.StartInfo.UseShellExecute = False m_process.Start() m_process.StandardInput.AutoFlush = True m_process.StandardInput.WriteLine("help") MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) This should show you the text that ftp sends you when you do that from the command line: Los comandos se pueden abreviar. Comandos: ! delete literal prompt send ? debug ls put status append dir mdelete pwd trace ascii disconnect mdir quit type bell get mget quote user binary glob mkdir recv verbose bye hash mls remotehelp cd help mput rename close lcd open rmdir Instead of that I'm getting the first line and 3 more with garbage, after that the call to ReadLine block like if there was no data available. Any hints about that?

• PLT Scheme Extracting field ids from structures

  - by Steve Knight

  I want to see if I can map PLT Scheme structure fields to columns in a DB. I've figured out how to extract accessor functions from structures in PLT scheme using the fourth return value of: (struct-type-info) However the returned procedure indexes into the struct using an integer. Is there some way that I can find out what the field names were at point of definition? Looking at the documentation it seems like this information is "forgotten" after the structure is defined and exists only via the generated-accessor functions: (<id>-<field-id> s). So I can think of two possible solutions: Search the namespace symbols for ones that start with my struct name (yuk); Define a custom define-struct macro that captures the ordered sequence of field-names inside some hash that is keyed by struct name (eek).
