• Silverlight, Grids, MVC, HTTP Post

  - by bplus

  I'm trying to create an editable grid using Asp.Net MVC 2 and Silverlight (specifically a grid that displays info from a db and allows users to update that info). So far I've managed to put a silverlight grid on an a view, using this technique However I have no way of getting the updated data from the silver light grid. Is there anyway to get these values posted back to my controller? I'm pretty new to Asp.Net MVC and I'm really only getting started using silverlight. Thanks for any help!

• Implement a WebDAV server in C#?

  - by HaukurHaf

  We've got a CMS system written in .NET C#. This system has editing facilities for templates (essentially HTML files) and various other support files such as CSS and javascript files. These "files" are not really files, but database records and they are edited using plain old textareas within the CMS system. To make editing these "files" easier, on idea was to implement WebDAV support in the CMS system for these files, so users could use some WebDAV client software to connect to the CMS and then open these in VS 2008 for example. Firstly, is this a feasible idea? Secondly, if so ... where do start? Any good articles out there about implementing a WebDAV server in C# to provide access to either physical documents or "pseudo" documents which are in reality just records in a database? Any input appreciated ....

• What is the maximum number of controls that a VBA form can hold?

  - by Lunatik

  I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

• Zend Framework Custom Validation Class Error Message

  - by remlabm

  The validation fails as it should but does not return the error message. $form->addElement('text', 'phone_number', array( 'required' => true, 'validators' => array( array('NotEmpty', true, array('messages' => 'Enter a valid Phone Number')), array('regex', false, array('pattern' => '/\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}/', 'messages' => 'Enter a valid Phone Number' )), 'CheckPhoneNumber'), ), )); Custom Class: class Custom_Validators_CheckPhoneNumber extends Zend_Validate_Abstract{ const IN_USE = 'inUse'; protected $_messageTemplates = array( self::IN_USE => "'%value%' is currently in use" ); public function isValid($value) { $this->_setValue($value); $user_check = Users::getActive(preg_replace("/[^0-9]/", "", $value)); if($user_check->id){ $this->_error(self::IN_USE); return false; } return true; } } Just fails does not give the "IN_USE" error.

• What's the correct way to stop a background process on Mac OS X?

  - by mcsheffrey

  I have an application with 2 components: a desktop application that users interact with, and a background process that can be enabled from the desktop application. Once the background process is enabled, it will run as a user launch agent independently of the desktop app. However, what I'm wondering is what to do when the user disables the background process. At this point I want to stop the background process but I'm not sure what the best approach is. The 3 options that I see are: Use the 'kill' command. Direct, but not reliable and just seems somewhat "wrong". Use an NSMachPort to send an exit request from the desktop app to the background process. This is the best approach I've thought of but I've run into an implementation problem (I'll be posting this in a separate query) and I'd like to be sure that the approach is right before going much further. Something else??? Thank you in advance for any help/insight that you can offer.

• How to make a secure login using UDID or device token?

  - by Erik B

  So I'm making an app where I want the users to be able add, edit and rate content, but I do not want to force them to register. Instead I was planning on just using their device id or device token to identify them. I'm planning on making both an iPhone and Android version, so I'm looking for a general solution, but the iPhone version has higher priority, so an iPhone specific solution would also be welcome. The problem is that I don't want just anyone to be able to use my web service by sending a phony device id or someone else's device id. How would the client prove to the server that it is providing the correct device id?

• How to do concurrent modification testing for grails application

  - by werner5471

  I'd like to run tests that simulate users modifying certain data at the same time for a grails application. Are there any plug-ins / tools / mechanisms I can use to do this efficiently? They don't have to be grails specific. It should be possible to fire multiple actions in parallel. I'd prefer to run the tests on functional level (so far I'm using Selenium for other tests) to see the results from the user perspective. Of course this can be done in addition to integration testing if you'd recommend to run concurrent modification tests on integration level as well.

• How to test the XML sent to a web service in Ruby/Rails

  - by Jason Langenauer

  I'm looking for the best way to write unit test for code that POSTs to an external web service. The body of the POST request is an XML document which describes the actions and data for the web service to perform. Now, I've wrapped the webservice in its own class (similar to ActiveResource), and I can't see any way to test the exact XML being generated by the class without breaking encapsulation by exposing some of the internal XML generation as public methods on the class. This seems to be a code smell - from the point-of-view of the users of the class, they should not know, nor care, how the class actually implements the web service call, be it with XML, JSON or carrier pigeons. For an example of the class: class Resource def new #initialize the class end def save! Http.post("http://webservice.com", self.to_xml) end private def to_xml # returns an XML representation of self end end I want to be able to test the XML generated to ensure it conforms to what the specs for the web service are expecting. So can I best do this, without making to_xml a public method?

• Display Computer Info on an ASP.NET Page

  - by Gene

  I want to build a page for end users to visit (in our MPLS Network) and it show the following information in regards to them: Computer Name OS Disk Space Memory IP Address Active Directory User Name Password Expiration Time (As defined by Global Policy) Maybe a few other things such as Trend Micro Office current version vs. their version, # of MS Updates needed (we utilize WSUS), and a few other things in the future. My question is how would I pull this information from the user when they visit the page? What is the proper function for this? Anyone have examples they wish to share for me to learn by if possible?

• Whats the best solution for a database used in conjunction with Maps in Android?

  - by Andrew

  Could someone please point me in the right direction. My project involves a database where users enter their address and other info from my website. This database is then referenced in my android application to show the locations of these addresses in my database. I have yet to start and just came up with this idea. My question is, what would be the best method to create a database easily modified through my website (mySQL, php, etc), and also easily referenced easily through Android and the Google Maps API? I need some ideas on the languages I will need to use to create this database and website so I can go buy the necessary books to start reading up. Thanks so much

• url rewriting + Asp.Net Login Form = Death

  - by xor88

  Hi, on our site we do url rewriting to generate massive amounts of database generated pages. on every page, there is a Login control for users. like this: Internal aspx page: /DB.aspx?id=123 User visible url: /ABC/123.aspx, /ABC/456.aspx ... (url rewritten) unfortunately, the tag on each page has an action attribute of "DB.aspx?id=123". when the user clicks the button the browser is posting to /ABC/DB.aspx?id=123 which of course does not exist. solutions i tried: 1. change the action attribute by subclassing HtmlForm. this destroys the all other forms on the site. 2. remove the action attribute (so that the browser is always posting to the same url). this works on the rewritten pages but on "/" (the default.aspx in the root dir) i get a message that the verb post is not allowed on "/" (iis 6 and i have no control over mappings) anybody?

• (Pathinfo vs fnmatch part 2) Speed benchmark reversed on Windows and Mac

  - by zaf

  On a previous question the pathinfo and fnmatch functions were benchmarked and the answers all came out opposite to my benchmark results. You can read the different results with the benchmark code here: http://stackoverflow.com/questions/2693428/pathinfo-vs-fnmatch I couldn't work it out until I ran the same code on a machine running vista. The results then matched the other users. My main machine is a mac. So, my questions are: Why do we get these two different results? Could this apply to other functions?

• How can I have a Visual Studio Report(.rdlc) with account information and also a chart in the same r

  - by Paul Mendoza

  I'm working on a report in Visual Studio 2008 with their Report tooling and I'm not sure how to approach this conceptually. I have a report I want to generate. At the top of the report will be a bunch of information about a customer of our site (Name, Address, Phone). Then below will be a chart of the purchases that customer has each month. My problem is that I want the content at the top of the page to use a query that selects from my Users table in my database. But then I need another query that gets all of the purchases grouped by month. I've thought one way to approach this would be to place a subreport on the parent report that only contained the chart. The parent report would have the details of the account. Is this the correct approach?

• JXTreeTable and BorderHighlighter Drawing Border on All Rows

  - by Kevin Rubin

  I'm using a BorderHighlighter on my JXTreeTable to put a border above each of the table cells on non-leaf rows to give a more clear visual separator for users. The problem is that when I expand the hierarchical column, all cells in the hierarchical column, for all rows, include the Border from the Highlighter. The other columns are displaying just fine. My BorderHighlighter is defined like this: Highlighter topHighlighter = new BorderHighlighter(new HighlightPredicate() { @Override public boolean isHighlighted(Component component, ComponentAdapter adapter) { TreePath path = treeTable.getPathForRow(adapter.row); TreeTableModel model = treeTable.getTreeTableModel(); Boolean isParent = !model.isLeaf(path.getLastPathComponent()); return isParent; } }, BorderFactory.createMatteBorder(2, 0, 0, 0, Color.RED)); I'm using SwingX 1.6.5.

• cron job for updating user profile data imported via facebook connect

  - by Abidoon Nadeem

  I want to write a cron job for updating user profile data on my website that I pull for users that register via facebook connect on my website. The objective is to keep their profile data on my website in sync with their profile data on facebook. So if a user updates their profile picture on facebook. I want to update his profile picture on my website as well via a cron job which will run every 24 hours. I wanted to know if this is possible and secondly if this is in violation of facebook privacy policy. Based on my research it seems doable but I wanted to know if anyone has already done something like this before. It would really help.

• Script Speed vs Memory Usage

  - by Doug Neiner

  I am working on an image generation script in PHP and have gotten it working two ways. One way is slow but uses a limited amount of memory, the second is much faster, but uses 6x the memory . There is no leakage in either script (as far as I can tell). In a limited benchmark, here is how they performed: -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 65.626 | 540,036 | 200 Two | 20.207 | 3,269,600 | 200 -------------------------------------------- And here is the average of the previous numbers (if you don't want to do your own math): -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 0.328 | 540,036 | 1 Two | 0.101 | 3,269,600 | 1 -------------------------------------------- Which method should I use and why? I anticipate this being used by a high volume of users, with each user making 10-20 requests to this script during a normal visit. I am leaning toward the faster method because though it uses more memory, it is for a 1/3 of the time and would reduce the number of concurrent requests.

• Google App Engine - Document Editor Creation/Tap Into Google Docs?

  - by Josh Patton

  What is the best way to create a custom document editor in GAE? I'm making a website meant for a School Robotics Club (With support for any other organization - DRY). We currently use Google services for online collaboration, I'm wondering if there is a way to tap into Google Docs and allow users to edit a Google Document without using Google Accounts or the Google Doc interface. If that is not possible (I've researched and I don't think it is), what is the best way to make a document editor? I want it completely on the website I'm creating, so I'm assuming just some javascript editor like TinyMCE + Ajax + Datastore. Is their anything that replicates Google Doc's/Microsoft Offices's/OpenOffice.org's feature set as far as fonts, spacing, alignment, justification, etc.?

• How to implement multi relationship in SQL Server?

  - by Ethan

  I’m trying to design a database to use with ASP.net MVC application. Here is the scenario: There are three entities and users can post their comments for each of these different entities. I just wonder how just put one table for Comments and link all other entities to it. Obviously, Comments table needs 3 references (foreign key) to those tables but as you know these foreign keys can’t be null and just one of them can be filled for each row. Is there any better way than implementing three different tables for each entity’s comments?

• JPA DAO integration test not throwing exception when duplicate object saved?

  - by HDave

  I am in the process of unit testing a DAO built with Spring/JPA and Hibernate as the provider. Prior to running the test, DBUnit inserted a User record with username "poweruser" -- username is the primary key in the users table. Here is the integration test method: @Test @ExpectedException(EntityExistsException.class) public void save_UserTestDataSaveUserWithPreExistingId_EntityExistsException() { User newUser = new UserImpl("poweruser"); newUser.setEmail("[email protected]"); newUser.setFirstName("New"); newUser.setLastName("User"); newUser.setPassword("secret"); dao.persist(newUser); } I have verified that the record is in the database at the start of this method. Not sure if this is relevant, but if I do a dao.flush() at the end of this method I get the following exception: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

• Evenly distribute items on the screen

  - by abolotnov

  I am trying to solve this little puzzle (the algorithm): I have N image icons and I want to distribute them evenly on users screen. Say, I put them in a table. If there is one image, there will be one cell in a table. If two - one row with two columns, if three - one row and three columns, if four - two rows, two columns... and so on until row space is gone and since then the table should only grow in columns without adding extra rows. I'm trying to figure an algorithm for this and perhaps this is something that has a solution already somewhere? My attempt is so far something like this: obtain_max_rows() obtain_visible_columns() if (number_of_pictures > max_rows*max_columns) { columns = roundup(number_of_pictures/max_rows) for(max_rows){generate row;for columns{generate column}} } else { **here comes to trouble...** } This logic is bit silly though - it somehow needs to think cases where there are 12 pictures on first screen and 2 on the other trying to balance it say 8/6 or somehow like that.
