• ASP.NET 1.0 site error after upgrade to VS.NET 2010

  - by Keith

  Help. I installed VS.NET 2010 and now my existing ASP.NET MVC application won't run. I checked that the 1.0 version of System.Web.Mvc is still referenced but when I browse my application, I get an error like this: "Compiler Error Message: CS1579: foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'". My partial view has this declaration: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<ProductModel" %> //various import statements <div <% foreach (var category in Model.Categories) { % <span<%= category.Name %</span <span<%= category.Market%</span <% } % </div For what it's worth, the source view shows ViewUserControl in red and gives a tool tip reading "Cannot resolve symbol 'ViewUserControl'". My working code didn't change, the only delta is that I upgraded to VS.NET 2010 (which includes MVC 2.0); I'm sure something is not referenced correctly but I cannot figure out what's going on.

• Visual Studio bug ~ 1 verified repro, 1 verified non-repro, any others?

  - by drachenstern

  In Visual Studio 2010 Pro (Version 10.0.30319.1 RTMRel), I noticed tonight that for some reason I kept getting a wider window for quick find, but thought I was losing my mind. So I exited, restarted, etc to verify. Here's my repro steps Open existing project (I don't think it matters which one) Press ctrlf and give it something to search for (?) in "current document" Press enter Press ctrlf Press enter goto 4 Can you reproduce a slowly expanding quick find window? Do I have some sort of wacky bugged out system? I'ld obviously like to submit a bug report to MS if this is indeed a viable repro.

• Storage servers architectural solution for backup. What is the best way? (pics inside)

  - by Kirzilla

  Hello, What is the best architecture for storage servers array? Needs... a) easy way to add one more server to array b) we don't have single backup server c) we need to have one backup for each "web" part of each server Group #1 : is cross-server-backuping scheme; the main disadvantage that we can't add one more server, we should add 2 servers in one time. Group #2 : is a Group #1, but with three and more servers. It also have a disadvantage - to add one more server we should move existing backup to it. Any suggestions? Thank you. Thank you.

• How should I move my code from dev to production?

  - by Teddy

  I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

• Do Ruby/Rails state machines exist that execute event transitions when a state change occurs?

  - by Bryan

  Hello All, Hopefully this isn't a silly question and I'm just not overlooking something in Ruby/Rails state machines (AASM, Transitions, AlterEgo, etc). From what I can tell, these state machine implementations operate on the preface that an event will get fired and the appropriate transition for that event will be triggered based on the old and new state. However, they don't seem to work the other way; say a user wants to change state from 'created' to 'assigned' and have the correct transition occur (rather than firing the event that causes the current state to be transitioned to the new state). Essentially, I want the user to be able to select a new state from a select box of available states and have the appropriate transition, guards, success callbacks, etc executed. Does anyone know if the existing state machine implementations support this?

• How Do I Programmatically Check if a WordPress Plugin Is Already Activated?

  - by Volomike

  I know I can use activate_plugin() from inside a given, active plugin in WordPress, to activate another plugin. But what I want to know is how do I programmatically check if that plugin is already active? For instance, this snippet of code can be temporarily added to an existing plugin's initial file to activate a partner plugin: add_action('wp','activatePlugins'); function activatePlugins() { if( is_single() || is_page() || is_home() || is_archive() || is_category() || is_tag()) { @ activate_plugin('../mypartnerplugin/thepluginsmainfile.php'); } } Then, use a Linux command line tool to spider all your sites that have this code, and it will force a page view. That page view will cause the above code to fire and activate that other plugin. That's how to programmatically activate another plugin from a given plugin as far as I can tell. But the problem is that it gets activated over and over and over again. What would be great is if I had an if/then condition and some function I could call in WordPress to see if that plugin is already activated, and only activate it once if not active.

• Importing Sqlite data into Google App Engine

  - by Keck

  I have a relatively extensive sqlite database that I'd like to import into my Google App Engine python app. I've created my models using the appengine API which are close, but not quite identical to the existing schema. I've written an import script to load the data from sqlite and create/save new appengine objects, but the appengine environment blocks me from accessing the sqlite library. This script is only to be run on my local app engine instance, and from there I hope to push the data to google. Am I approaching this problem the wrong way, or is there a way to import the sqlite library while running in the local instance's environment?

• Is it faster to do the pages first and CSS second, or should I do them at the same time?

  - by Fred Haslam

  I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

• Mac-native text editor that can syntax-highlight diff files?

  - by strawtarget

  I do something like "svn diff /mystuff/current.diff". I want to view this .diff file with syntax highlighting. jEdit does it, but it's a huge beast and it takes a while to start up. I want something lightweight/native. Smultron/Fraise, TextWrangler, TextEdit, Dashcode don't seem to highlight .diff files. FileMerge seems to want to generate diff files, not show you existing ones. TextMate does the trick, but it's not free. I'd feel happier dropping $50 US if I was going to take advantage of it for anything more than a diff viewer. Are there any alternatives to jEdit or TextMate that I should consider?

• Update specific rows in LINQ to SQL result set.

  - by davemackey

  I have a page with a form on it and needs a range of dates. Thus I've placed a number of textboxes on the page into which users can type dates. When the user clicks the save button I want to trigger a LINQ update to the SQL Server...all the rows already exist, so I'm just updating existing data. How can I do this? For example, lets say my table looks like this: Column Names: Description dateValue Column Values: Birthdate 1/1/1990 Anniversary 1/10/1992 Death 1/1/1993 I want to do something like this: hupdate.Description("Birthdate").dateValue = TextBox1.Text hupdate.Description("Anniversary").dateValue = TextBox2.Text hupdate.Description("Death").dateValue = TextBox3.Text hconfig.SubmitChanges() Is there a way to do this with LINQ?

• Xaml not WPF

  - by xan

  I am interested in using Xaml with expression blend for creating user interfaces in an application. However, because of the limitations of the target architecture, I cannot use WPF or C#. So, what I am interested in is in any examples / existing projects or advice from anyone who has experiance of this technology on the use of Xaml in it's "Pure" form as a specification language not tied to WPF. Specific questions: 1) Is it possible to use Blend + Xaml without the WPF elements, or without C# backing classes? 2) Are there any other implementations of Xaml parsers etc. which use different architectures, and can they work with blend or similar tools. 3) Are there alternative editor / designer tools which can help in this situation? I am aware of the MyXaml and MycroXaml projects, and have found a lot of resources on the web about Xaml, but 99% of it relates directly to WPF. This is fine for understanding the concepts of Xaml, but doesn't help with the implimentation I need. Many thanks!

• codemirror fails when adding </textarea> tag inside it

  - by Jorre

  I'm using codemirror http://marijn.haverbeke.nl/codemirror/ to let users create their own web templates inside a web application. Codemirror works great, except for the time that users have put a tag inside their source code. When I load that up inside code mirror, it breaks everything in the source code that follows after because it thinks my codemirror text area is closed. I'm using the following way to launch codemirror: CodeMirror.fromTextArea('code') It works great on my existing textarea "code" except when users add inside their templates (in the codemirror textarea). Any help is much appreciated!

• Customizing Hibernate Criteria - Adding conditions to a left join

  - by Douglas Ferguson

  I need to be able to do the following: Select * from Table1 left join Table2 on id1 = id2 AND i1 = ? Hibernate criteria doesn't allow be to specify the i1 = ? part. The existing code is using hibernate criteria and it would be a huge refactor to swap out for HQL Does anybody have any tips how I could implement this differently or any way to override the Hibernate Criteria? I'm not opposed to cracking open hibernate and modifying, but when I began to dig it, there seems to be layers upon layers of abstractions. I never found the the point where SQL is actually generated...

• Why does my app crash when I add an row to the table view?

  - by mystify

  I'm adding a row like this, when a button is pressed. It must be the very first row in the first section: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; I don't call anything else here. No -reloadData. I keep getting this: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (6) must be equal to the number of rows contained in that section before the update (6), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).'

• How to implement blocking request-reply using Java concurrency primitives?

  - by Uri

  My system consists of a "proxy" class that receives "request" packets, marshals them and sends them over the network to a server, which unmarshals them, processes, and returns some "response packet". My "submit" method on the proxy side should block until a reply is received to the request (packets have ids for identification and referencing purposes) or until a timeout is reached. If I was building this in early versions of Java, I would likely implement in my proxy a collection of "pending messages ids", where I would submit a message, and wait() on the corresponding id (with a timeout). When a reply was received, the handling thread would notify() on the corresponding id. Is there a better way to achieve this using an existing library class, perhaps in java.util.concurrency? If I went with the solution described above, what is the correct way to deal with the potential race condition where a reply arrives before wait() is invoked?

• EXT JS toLayout on Viewport doesnt show anything...

  - by Nazariy

  After reading many example about adding new components in to existing container without reloading whole page I run in to small problem while combining tree and tabs inside Viewport component. What I'm trying to do is to register on click event to tree node and load in to content container new component, depending on node type it can be tabpanel, gridpanel or any other available component. here is short example of tree object: { xtype: 'treepanel', id: 'tree-panel', listeners: { click: function(n) { var content = Ext.getCmp('content-panel'); content.setTitle(n.attributes.qtip); //remove all components from content-panel content.removeAll(); content.add(dummy_tabs2); content.doLayout(); return; } }} All DOM manipulation went fine, everything registered properly, new Title shown, but dummy_tabs2 are not shown. I did try to set various properties for doLayout(true|false, true|false) but nothing happens. Am I doing something wrong?

• Accessing PostGIS spatial data from Rails

  - by Lakitu

  I need to use an existing PostGIS database from my Rails application. So far I am able to access the DB just fine, GeoRuby nicely converts the 'geom' column into a Point object. What I am looking for is an easy way to execute ActiveRecord-like queries on those tables, e.g. Poi.find_within_radius(...) or similar spatial queries like distance calculations et. al. I tried several combinations of geokit, accompanying rails plugins but I'm quite sure there must be something better out there in the ruby/rails universe. Any hints?

• Make a Linq-to-SQL Generated User Class Inherit from MembershipUser

  - by Adam Albrecht

  I am currently building a custom Membership Provider for my Asp.net MVC website. I have an existing database with a Users table and I'm using Linq-to-Sql to automatically generates this class for me. What I would like to do is have this generated User class inherit from the MembershipUser class so I can more easily use it in my custom Membership Provider in methods such as GetUser. I already have all the necessary columns in the table. Is there any way to do this? Or am I going about this the completely wrong way? Thanks!

• Upgrading a SharePoint list instance that was deployed via feature

  - by Goldmember

  I'm curious how others address this issue. Using VSEWSS 1.3, I have created a site content type, a list definition (w event receivers), and a list instance. All of them are in the same WSP solution and each is activated individually via features. Now let's assume that all the features have been activated for some time, and the list instance contains a number of items (that can't be deleted). Now suppose I need to make a change to the schema.xml (inject some javascript, modify views, whatever) of the list. Is it even possible to "upgrade" the schema of the existing list instance? Otherwise I would think I'm stuck creating a new instance and copying items over.

• Track each request to the website using HttpModule

  - by stacker

  I want to save each request to the website. In general I want to include the following information: User IP, The web site url, user-if-exist, date-time. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.

• After Trigger execute before constraint check in oracle

  - by satakare

  Hi, I have After Insert/Update trigger on Table T1 which get the referential data for Col1 from T2 and does some work and insert it into another table. The col1 is FK to Table T2. When user insert the incorrect or non existing value into the Col1 and if trigger is disabled I am getting constraint error that is fine. But when trigger is enabled and user insert the wrong value in Col1 trigger is getting fired and shows the 'no data found' error message. Actually I am expecting the table to throw constraint error, but trigger is throwing it. Please let me know your comments about this trigger behaviour.

• Query DNSBL or other block lists using PHP

  - by 55skidoo

  Is there any way to use PHP code to query a DNSBL (block list) provider and find out if the IP address submitted is a bad actor? I would like to take an existing IP address out of a registration database, then check whether it's a known block-listed IP address by performing a lookup on it, then if it's a blacklisted, do an action on it (such as, delete entry from registration database). Most of the instructions I have seen assume you are trying to query the blocklist via a mail server, which I can't do. I tried querying via web browser by typing in queries such as "58.64.xx.xxx.dnsbl.sorbs.net" but that didn't work.

• Preview result of update/insert query whithout comitting changes to database in MySQL?

  - by Camsoft

  I am writing a script to import CSV files into existing tables within my database. I decided to do the insert/update operations myself using PHP and INSERT/UPDATE statements, and not use MySQL's LOAD INFILE command, I have good reasons for this. What I would like to do is emulate the insert/update operations and display the results to the user, and then give them the option of confirming that this is OK, and then committing the changes to the database. I'm using InnoDB database engine with support for transactions. Not sure if this helps but was thinking down the line of insert/update, query data, display to user, then either commit or rollback transaction? Any advise would be appreciated.
